NAD 122-126 P53 Homo sapiens 252-255 31932645-2 2020 Although previous studies have revealed that some sophoridine derivatives could induce DNA breakage, the underlying mechanisms of inhibition of DNA damage repair (ATR inactivation) and the apoptosis independent of p53, have not been elucidated. matrine 50-61 P53 Homo sapiens 214-217 32371497-3 2020 Here, using human breast cancer cell models, we identified a pathway in which changes in the extramitochondrial-free NADH:NAD+ ratio signaled through the CtBP family of NADH-sensitive transcriptional regulators to control the abundance and activity of p53. NAD 169-173 P53 Homo sapiens 252-255 32371497-4 2020 NADH-free forms of CtBPs cooperated with the p53-binding partner HDM2 to suppress p53 function, and loss of these forms in highly glycolytic cells resulted in p53 accumulation. NAD 0-4 P53 Homo sapiens 82-85 32371497-4 2020 NADH-free forms of CtBPs cooperated with the p53-binding partner HDM2 to suppress p53 function, and loss of these forms in highly glycolytic cells resulted in p53 accumulation.

CHEMBL2152433 0-3 P53 Homo sapiens 27-30 30613833-6 2018 Results: Significant resistance to 5-FU resulted from p53-loss or from gain-of-function (GOF) mutation (R248W) and was greatest when GOF mutation was coupled with loss of wild-type p53. Fluorouracil 35-39 P53 Homo sapiens 181-184 30488759-4 2018 Here we mathematically modeled the recently dual-phase p53 dynamics under doxorubicin treatment.

Fluorouracil 29-33 P53 Homo sapiens 61-65 30488759-5 2018 We found that p53 could perform sequential pulses followed by a high-amplitude terminal pulse at relatively low doxorubicin treatment, whereas p53 became steadily accumulated when damage level was high. Doxorubicin 112-123 P53 Homo sapiens 14-17 30488759-8 2018 Furthermore, lower binding affinity and degradation rate of p53 target genes could favorably discriminate high and low dose doxorubicin treatment.

Doxorubicin 83-94 P53 Homo sapiens 48-51 26967060-6 2016 This appears to be related to reduced phosphorylation of serine residues in both N-terminal and C-terminal regions of the p53 molecule.

Cisplatin 100-104 P53 Homo sapiens 61-64 27077811-6 2016 We have found that a treatment with a low dose (75 nM) of MK-1775, a recently described specific chemical inhibitor of Wee1, decreases CDDP-induced H2AX phosphorylation in p53-negative cells and enhances the Wip1-sensitization of p53-negative tumors. Cisplatin 135-139 P53 Homo sapiens 172-175 27077811-6 2016 We have found that a treatment with a low dose (75 nM) of MK-1775, a recently described specific chemical inhibitor of Wee1, decreases CDDP-induced H2AX phosphorylation in p53-negative cells and enhances the Wip1-sensitization of p53-negative tumors. Cisplatin 135-139 P53 Homo sapiens 230-233 32263194-12 2016 In conclusion, GNP-(PHA-E)-GEM could induce growth inhibition and cytotoxicity, which was mediated through inhibition of EGFR phosphorylation and the switching on of p53 that causes cell apoptosis of NSCLC cells A-549 and H292. gnp-(pha-e)-gem 15-30 P53 Homo sapiens 166-169 26840531-5 2016 Moreover, Tf-NGO@HPIP effectively induced cancer-cell apoptosis through activation of superoxide-mediated p53 and MAPK pathways along with inactivation of ERK and AKT. Superoxides 86-96 P53 Homo sapiens 106-109 26967561-1 2016 We have previously shown that melatonin exerts tumor suppressor activities by inducing the p38-p53 axis.

Oligonucleotides 7-22 P53 Homo sapiens 165-169 26148235-3 2016 Interestingly, RNF31 decreased p53 stability, whereas depletion of RNF31 in breast cancer cells caused cell cycle arrest and cisplatin-induced apoptosis in a p53-dependent manner. Cisplatin 125-134 P53 Homo sapiens 158-161 26148237-7 2016 Comparative X-ray crystallographic analyses of MDMX and of pTyr99 MDMX in complex with PMI as well as modeling studies reveal that the phosphate group of pTyr99 imposes extensive steric clashes with the C-terminus of PMI or p53 peptide and induces a significant lateral shift of the peptide ligand, contributing to the dramatic decrease in the binding affinity of MDMX for p53.

Sirolimus 45-54 P53 Homo sapiens 122-125 27044825-14 2016 sCD40L in combination with cisplatin decreased the expression levels of GST-pi, LRP, Survivin, p53 and Bcl-2 in both epithelial ovarian cancer cell lines. Cisplatin 27-36 P53 Homo sapiens 95-98 26842845-5 2016 This inhibition was due to the Profilin mediated attenuation of IkappaBalpha degradation, thereby preventing p65 nuclear translocation and low NF-kappaB DNA binding activity.Moreover, Profilin increases level of p53 in the presence of known inducers, such as doxorubicin, vinblastine, and benzofuran. Doxorubicin 259-270 P53 Homo sapiens 212-215 26704388-11 2016 A role for p53 appears important as GCS-100 induces p53 expression and shRNA knockdown of p53 protected OCI-AML3 cells from the cytotoxic effects of the GCS-100/ABT-737 treatment combination. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 161-164 P53 Homo sapiens 11-14 26704388-11 2016 A role for p53 appears important as GCS-100 induces p53 expression and shRNA knockdown of p53 protected OCI-AML3 cells from the cytotoxic effects of the GCS-100/ABT-737 treatment combination. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 161-164 P53 Homo sapiens 52-55 26704388-11 2016 A role for p53 appears important as GCS-100 induces p53 expression and shRNA knockdown of p53 protected OCI-AML3 cells from the cytotoxic effects of the GCS-100/ABT-737 treatment combination. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 161-164 P53 Homo sapiens 52-55 27044842-0 2016 The novel anthraquinone derivative IMP1338 induces death of human cancer cells by p53-independent S and G2/M cell cycle arrest.

Cisplatin 111-120 P53 Homo sapiens 48-51 27044842-7 2016 In addition, IMP1338 markedly induced the phosphorylation of histone H2AX and Chk1 in both cell lines while the combination of 5-fluorouracil (5-FU) and radiation inhibited the viability of HCT116, HCT116 p53(-/-), and HT29 cells compared to 5-FU or radiation alone. Fluorouracil 127-141 P53 Homo sapiens 205-208 26851235-2 2016 Although gene association network analysis demonstrated gene expression profile changes in the liver of human TP53 knock-in mice after acute AAI exposure, to date, whether AAI causes hepatic tumorigenesis is still not confirmed. aristolochic acid I 141-144 P53 Homo sapiens 110-114 27044842-7 2016 In addition, IMP1338 markedly induced the phosphorylation of histone H2AX and Chk1 in both cell lines while the combination of 5-fluorouracil (5-FU) and radiation inhibited the viability of HCT116, HCT116 p53(-/-), and HT29 cells compared to 5-FU or radiation alone.

Lysine 30-36 P53 Homo sapiens 15-18 26851285-3 2016 Here we demonstrate that acetylation of p53 at Lys-120 up-regulates its transcriptional activity toward Apaf-1, a core component in the mitochondrial apoptotic pathway, and thus sensitizes caspase activation and apoptosis. Lysine 47-50 P53 Homo sapiens 40-43 26851285-7 2016 Therefore, HDAC inhibitors can induce p53 acetylation at lysine 120, which in turn enhances mitochondrion-mediated apoptosis through transcriptional up-regulation of Apaf-1.

Estradiol 0-9 P53 Homo sapiens 60-63 26493598-6 2015 We then show that U87- p53 inactivity can be rescued by zinc (Zn). Zinc 62-64 P53 Homo sapiens 23-26 26492315-4 2015 Our results suggest that combined treatment with rosiglitazone and LA-12 might be promising anticancer strategy in colon-derived tumours regardless of their p53 status, and also favourable in those defective in PTEN function. Rosiglitazone 49-62 P53 Homo sapiens 157-160 25619836-0 2015 Three-dimensional microenvironment confers enhanced sensitivity to doxorubicin by reducing p53-dependent induction of autophagy. Doxorubicin 67-78 P53 Homo sapiens 91-94 25619836-6 2015 Moreover, in the monolayer-cultured cells, DOXO treatment led to increases in p53 and DRAM-1 expression, which is a p53-dependent activator of autophagy that functions in response to DNA damage.

Platinum 88-96 P53 Homo sapiens 55-58 26505347-7 2015 Interestingly, in the kidney, cisplatin treatment can activate AMP-activated protein kinase (AMPK), a signaling molecule that is also critical for p53-mediated inactivation of mammalian target of rapamycin (mTOR) pathways. Cisplatin 30-39 P53 Homo sapiens 147-150 26540407-5 2015 Surprisingly, the genetic or chemical silencing of p53 significantly enhanced the cytotoxic effects of both VMY and the DNA damaging drug, doxorubicin. Doxorubicin 139-150 P53 Homo sapiens 51-54 26505347-10 2015 Given the fact that p53 can regulate autophagy by inactivating mTOR via AMPK, our results suggest that the p53 pathway may also play a critical role in the pathogenesis of cisplatin-induced renal damage.

Reactive Oxygen Species 198-201 P53 Homo sapiens 184-187 26264138-7 2015 The growth inhibitory effect of P53 was partially reversed by the antioxidant N-acetylcysteine. Acetylcysteine 78-94 P53 Homo sapiens 32-35 26264138-8 2015 Our data strengthen the idea that overexpression of a single gene (trx2) decreases the p53-mediated cell death by decreasing ROS accumulation. Reactive Oxygen Species 125-128 P53 Homo sapiens 87-90 26408691-4 2015 Treatment of tumor cells with the antioxidant N-acetylcysteine was able to prevent Zn(2+)-induced apoptosis, as well as the increase of p53 and FAS ligand protein induced by zinc. Acetylcysteine 46-62 P53 Homo sapiens 136-139 26408691-5 2015 Zinc induces apoptosis in melanoma cells by increasing ROS and this effect may be mediated by the ROS-dependent induction of p53 and FAS/FAS ligand.

Resveratrol 27-38 P53 Homo sapiens 126-129 26250568-4 2015 Magnolol also blocked cell cycle progression at G0 /G1 phase and induced mitochondrial-related apoptosis by upregulating p53 and p21 protein levels and by downregulating cyclin D1, CDC25A, and Cdk2 protein levels. magnolol 0-8 P53 Homo sapiens 121-124 26231140-7 2015 These compounds appeared the most effective inducers of p53 in the TPA-challenged neutrophils, what may suggest that pro-apoptotic activity of these stilbenes might be related to p53 activation. Tetradecanoylphorbol Acetate 67-70 P53 Homo sapiens 56-59 26231140-7 2015 These compounds appeared the most effective inducers of p53 in the TPA-challenged neutrophils, what may suggest that pro-apoptotic activity of these stilbenes might be related to p53 activation. Tetradecanoylphorbol Acetate 67-70 P53 Homo sapiens 179-182 26205069-5 2015 The typical mechanism of cisplatin action involves DNA damage, activation of p53 protein and induction of cell death, as previously described for titanium ions.

Fluorouracil 86-100 P53 Homo sapiens 109-112 25971460-9 2015 Finally, we showed that the induction of Sestrin-2 by Sevoflurane was mediated by p53. Sevoflurane 54-65 P53 Homo sapiens 82-85 26314369-0 2015 Zn(II)-curc targets p53 in thyroid cancer cells. Zinc 0-6 P53 Homo sapiens 20-23 26314369-5 2015 Here, we investigated whether Zn(II)-curc could affect p53 in thyroid cancer cells with both p53 mutation (R273H) and wild-type p53. Zinc 30-36 P53 Homo sapiens 55-58 26314369-8 2015 In addition, Zn(II)-curc triggered p53 target gene expression in wild-type p53-carrying cells. Zinc 13-19 P53 Homo sapiens 35-38 26314369-8 2015 In addition, Zn(II)-curc triggered p53 target gene expression in wild-type p53-carrying cells. Zinc 13-19 P53 Homo sapiens 75-78 26314369-10 2015 Taken together, our data indicate that Zn(II)-curc promotes the reactivation of p53 in thyroid cancer cells, providing in vitro evidence for a potential therapeutic approach in thyroid cancers. Zinc 39-45 P53 Homo sapiens 80-83 26315556-0 2015 Myricetin inhibits proliferation of cisplatin-resistant cancer cells through a p53-dependent apoptotic pathway. myricetin 0-9 P53 Homo sapiens 79-82 26315556-0 2015 Myricetin inhibits proliferation of cisplatin-resistant cancer cells through a p53-dependent apoptotic pathway.

Metformin 15-24 P53 Homo sapiens 153-156 25762091-5 2015 RESULTS: Here, we show that expression of Rap2B was induced by nocodazole in a p53-dependent manner. Nocodazole 63-73 P53 Homo sapiens 79-82 25929783-5 2015 Cell death was accompanied by a significant increase in phosphorylated p53 at serine 15 and accumulation of PTEN. Serine 78-84 P53 Homo sapiens 71-74 25659586-6 2015 We report here the ability of p73 to upregulate the expression of the A2B receptor, a recently characterized p53 target that effectively promotes cell death in response to extracellular adenosine--a metabolite that accumulates during various forms of cellular stress. Adenosine 186-195 P53 Homo sapiens 109-112 24798859-5 2015 Here, we report that the environmental carcinogen benzo[a]pyrene (BaP) upregulated the expression of seven p53-targeting miRNAs (miR-25, miR-15a, miR-16, miR-92, miR-125b, miR-141, and miR-200a), while 2,3,7,8-tetrachlorodibenzo-rho-dioxin (TCDD) upregulated two of them (miR-25 and miR-92) in MM cells. Polychlorinated Dibenzodioxins 241-245 P53 Homo sapiens 107-110 26208523-11 2015 These data indicate that the DACH carrier ligand in oxaliplatin triggers signaling via the p53-miR-34a-E2F axis, leading to transcriptional regulation that ultimately results in accumulation of dUTP and reduced dTTP biosynthesis, potentially enhancing 5-FU cytotoxicity. Fluorouracil 252-256 P53 Homo sapiens 91-94 25959925-4 2015 Cisplatin-resistant A549R cells treated with Ru@L-SeNPs-siRNA demonstrated significant downregulation of P-glycoprotein (P-gp) expression, resulting in unprecedented enhanced cytotoxicity through the induction of apoptosis with the involvement of phosphorylation of p53, MAPK and PI3K/Akt signaling pathways. Cisplatin 0-9 P53 Homo sapiens 266-269 26004085-10 2015 Our findings strongly indicate that concomitant inactivation of the p53- and pRB- pathways predict resistance towards anthracyclines and mitomycin in breast cancer in vivo. Anthracyclines 118-132 P53 Homo sapiens 68-71 25659586-9 2015 Moreover, treatment of p53-null cancer cells with the chemotherapeutic drug adriamycin (doxorubicin) induces A2B in a p73-dependent manner and, in combination with an A2B agonist, substantially enhances apoptotic death. Doxorubicin 76-86 P53 Homo sapiens 23-26 25659586-9 2015 Moreover, treatment of p53-null cancer cells with the chemotherapeutic drug adriamycin (doxorubicin) induces A2B in a p73-dependent manner and, in combination with an A2B agonist, substantially enhances apoptotic death. Doxorubicin 88-99 P53 Homo sapiens 23-26 25659586-10 2015 We therefore propose an alternate and distinct p53-independent pathway to stimulate programmed cell death involving p73-mediated engagement of adenosine signalling. Adenosine 143-152 P53 Homo sapiens 47-50 26317157-0 2015 Depletion of the cisplatin targeted HMGB-box factor UBF selectively induces p53-independent apoptotic death in transformed cells. Cisplatin 17-26 P53 Homo sapiens 76-79 26313152-8 2015 Expression of anti-apoptotic proteins Bcl-2 and Mcl-1 and DNA repair associated molecules ATM, CHK1, TP73, p53, and ERCC1 were significantly up regulated in cisplatin-treated A549sc and H157sc cells, but no increase was detected in A549IL-6si and H157IL-6si cells. Cisplatin 157-166 P53 Homo sapiens 107-110 26302161-7 2015 This study shows that p53 is activated in astrocytes during ischemia and that inhibition of the activity of this molecule prevents not only OGD-induced neuronal and astrocytic death but also astrocyte activation and impaired glutamate uptake.

Cyclosporine 123-136 P53 Homo sapiens 154-157 26342198-9 2015 Furthermore, blockage of the beta1-integrin/FAK/PI3K/AKT/mTOR pathway by siRNA or specific chemical inhibitors, or rescue of p53 activation can partially reverse the switch of glucose metabolism and inhibit the migration of Twist-overexpressing MCF10A cells and Twist-positive breast cancer cells. Glucose 176-183 P53 Homo sapiens 125-128 26342198-10 2015 Thus, our data suggest that Twist promotes reprogramming of glucose metabolism in MCF10A-Twist cells and Twist-positive breast cancer cells via activation of the beta1-integrin/FAK/PI3K/AKT/mTOR pathway and inhibition of the p53 pathway.

Superoxides 66-76 P53 Homo sapiens 52-55 26337205-12 2015 Specifically, the findings indicate 1) that glycolysis plays an essential role in autophagy by limiting superoxide levels and maintaining expression of ATG genes required for autophagic vesicle maturation, 2) that p53 can promote or inhibit autophagy depending on the status of glycolysis, and 3) that inhibiting protective autophagy can expand the breadth of cells susceptible to Nutlin-3a induced apoptosis. Superoxides 104-114 P53 Homo sapiens 214-217 26815194-0 2015 [p14ARF enhances cisplatin-induced apoptosis in human osteosarcoma cells in p53-independent pathway].

Arginine 133-136 P53 Homo sapiens 50-53 24858040-6 2015 We identified the uric acid transporter SLC2A9 (also known as GLUT9) as a direct p53 target gene and a key downstream effector in the reduction of reactive oxygen species (ROS) through transporting uric acid as a source of antioxidant. Reactive Oxygen Species 147-170 P53 Homo sapiens 81-84 24858040-9 2015 The increased production of ROS because of p53 loss was rescued by SLC2A9 expression.

Serine 27-30 P53 Homo sapiens 46-49 25605022-0 2015 p53 activates G1 checkpoint following DNA damage by doxorubicin during transient mitotic arrest. Doxorubicin 52-63 P53 Homo sapiens 0-3 25774791-4 2015 RESULTS: The pooled data by a fixed-effects model suggested an increased risk of CM associated with p53 Arg72Pro polymorphism under the genetic model of Arg/Pro vs. Pro/Pro without heterogeneity (ORArg/Pro vs. Pro/Pro = 1.76, 95% CI = 1.55-1.99, Pheterogeneity = 0.075). Arginine 104-107 P53 Homo sapiens 100-103 26064201-1 2015 BACKGROUND: The polymorphism of TP53 codon 72, a transversion of G to C (Arg to Pro), has been demonstrated to be associated with the risk for lung cancer. Arginine 73-76 P53 Homo sapiens 32-36 26064201-3 2015 Thus, we performed a meta-analysis by pooling all currently available case-control studies to estimate the effect of TP53 codon 72 Arg/Pro polymorphism on the development of lung cancer in the Chinese population.

Hydrogen Peroxide 79-96 P53 Homo sapiens 182-186 25766317-7 2015 We conclude that the level of ROS is crucial in initiating p53"s transcription of p21 leading to senescence. Reactive Oxygen Species 30-33 P53 Homo sapiens 59-62 25766317-8 2015 It is p21"s ability to sustain elevated levels of ROS, in turn, that allows for a long-term oxidative stress, and ensures an active p53-p21-ROS signaling loop.

Arginine 46-54 P53 Homo sapiens 70-73 25750340-1 2015 BACKGROUND/AIM: We undertook a case-control and a case-case study to examine the possible association of p53 codon72 polymorphism with the breast cancer risk and resistance to anthracycline-based chemotherapy. Anthracyclines 176-189 P53 Homo sapiens 105-108 25776512-11 2015 CONCLUSIONS: Taken together, the results of our study clearly suggested that the cell death induced by the combination of RSV-GNPs would involve alteration in expression of p53, p21, caspase-3, Bax, Bcl-2 and NF-kappaB, indicating oxidative mechanism in NCI-H460 cells.

Fluorouracil 109-113 P53 Homo sapiens 61-64 25776512-9 2015 Moreover, Western blotting analysis showed that apoptosis induced by RSV-GNPs is associated with the increased Bax, p53, p21, caspase-3 protein levels, and decreased Bcl-2 and NF-kappaB proteins expression, which indicates the involvement of mitochondria-dependent apoptosis in the anticancer efficacy of RSV-GNPs in NCI-H460 cells. Resveratrol 69-72 P53 Homo sapiens 116-119 25582697-5 2015 Molecular analysis of lymphomas revealed that arginine methylation of p53 selectively suppresses expression of crucial proapoptotic and antiproliferative target genes, thereby sustaining tumor cell self-renewal and proliferation and bypassing the need for the acquisition of inactivating p53 mutations. Arginine 46-54 P53 Homo sapiens 288-291 25667616-10 2015 Furthermore, in the naringenin-treated K562 cells, the labeling index of proliferating cell nuclear antigen was observed to be increased by immunochemical staining, the mRNA and protein expression levels of p21/WAF1 were strongly upregulated in reverse transcription-polymerase chain reaction and western blot analyses, whereas p53 gene expression was not significantly changed. naringenin 20-30 P53 Homo sapiens 328-331 25595558-7 2015 Consistent with this observation in SK-MEL28 cells, Sp1 was necessary for the tamoxifen-regulated Raf-1:ER to induce p21(CIP1) transcription in U251 cells, in which TP53 is mutated.

Curcumin 97-105 P53 Homo sapiens 149-152 25658320-7 2015 To a different extent, either the antioxidant N-acetyl-cysteine or the p53 inhibitor, Pifithrin-alpha, recover cell viability and decrease ROS formation. Reactive Oxygen Species 139-142 P53 Homo sapiens 71-74 25658463-9 2015 Treatment of wild-type TP53 neuroblastoma cell lines with both GSK2830371 and either doxorubicin or carboplatin resulted in enhanced cell death, mediated through caspase 3/7 induction, as compared to either agent alone. Doxorubicin 85-96 P53 Homo sapiens 23-27 25567764-1 2015 We report in this work that the Abeta peptide directly interacts with tubulin close to the vinblastine and GTP/GDP binding site, inhibits the tubulin polymerization rate, induces tubulin aggregation, causes cell shrinking, enhances Mad2, BubR1, p53, and p21 activation in MCF7 cells and induces the apoptotic death of A549, HeLa and MCF7 cells.

Fluorouracil 198-202 P53 Homo sapiens 92-95 25444916-0 2015 Curcumin promotes apoptosis by activating the p53-miR-192-5p/215-XIAP pathway in non-small cell lung cancer. Curcumin 0-8 P53 Homo sapiens 46-49 25444916-7 2015 Curcumin also promoted miR-192-5p/215 expressions in A549 cells (p53 wild type) but not in H1299 cells (p53-null). Curcumin 0-8 P53 Homo sapiens 65-68 25444916-8 2015 Conditional knockdown of p53 by tetracycline inducible expression system significantly abrogated curcumin-induced miR-192-5p/215 upregulation in the p53 wild-type H460, A427 and A549 cells. Curcumin 97-105 P53 Homo sapiens 25-28 25444916-9 2015 Conversely, ectopic expression of exogenous wild-type but not R273H mutant p53 in the p53-null H1299 cells enabled miR-192-5p/215 response to curcumin treatment.

Curcumin 142-150 P53 Homo sapiens 86-89 25444916-12 2015 Taken together, this study highlights that the proapoptotic effects of curcumin depend on miR-192-5p/215 induction and the p53-miR-192-5p/215-XIAP pathway is an important therapeutic target for non-small cell lung cancer. Curcumin 71-79 P53 Homo sapiens 123-126 25445786-6 2015 SIRT7 overexpressing cells when treated with low dose of doxorubicin (0.25 microM) showed delayed onset of senescence, lesser accumulation of DNA damage marker gammaH2AX and lowered levels of growth arrest markers viz., p53 and p21 when compared to doxorubicin treated control GFP expressing cells.

Serine 62-68 P53 Homo sapiens 55-58 25445786-8 2015 When treated with higher dose of doxorubicin (>1 microM), SIRT7 conferred resistance to apoptosis by attenuating stress activated kinases (SAPK viz., p38 and JNK) and p53 response thereby shifting the cellular fate towards senescence. Doxorubicin 33-44 P53 Homo sapiens 170-173 25445786-10 2015 SIRT7 mediated resistance to doxorubicin induced apoptosis and senescence was lost when p53 level was restored by nutlin treatment.

Cisplatin 137-146 P53 Homo sapiens 75-79 25504633-6 2015 Consistent with its ability to chemosensitize, MK-1775 abrogated the cisplatin-induced G2 block in p53-defective cells leading to mitotic arrest associated with a senescence-like phenotype. Cisplatin 69-78 P53 Homo sapiens 99-102 25504633-7 2015 Furthermore, MK-1775 enhanced the efficacy of cisplatin in vivo in tumors harboring TP53 mutations.

Phosphatidylinositol Phosphates 100-103 P53 Homo sapiens 205-208 25404730-0 2015 p53 Protein-mediated regulation of phosphoglycerate dehydrogenase (PHGDH) is crucial for the apoptotic response upon serine starvation. Serine 117-123 P53 Homo sapiens 0-3 25404730-2 2015 Here we report that PHGDH, the key metabolic enzyme that catalyzes the rate-limiting step of the serine biosynthesis pathway, is a target of p53 in human melanoma cells. Serine 97-103 P53 Homo sapiens 141-144 25404730-3 2015 p53 suppresses PHGDH expression and inhibits de novo serine biosynthesis. Serine 53-59 P53 Homo sapiens 0-3 25446071-3 2015 Here we report for the first time that cadmium, nickel and cobalt, which have already been shown to disturb various DNA repair mechanisms, can also influence p63 and p73 sequence-specific DNA binding activity and transactivation of p53 family target genes. Cadmium 39-46 P53 Homo sapiens 232-235 25446071-4 2015 Based on results of electrophoretic mobility shift assay and luciferase reporter assay, we conclude that cadmium inhibits sequence-specific binding of all three core domains to p53 consensus sequences and abolishes transactivation of several promoters (e.g. BAX and MDM2) by 50muM concentrations. Cadmium 105-112 P53 Homo sapiens 177-180 25446071-5 2015 In the presence of specific DNA, all p53 family core domains were partially protected against loss of DNA binding activity due to cadmium treatment.

Serine 145-151 P53 Homo sapiens 197-200 25446071-7 2015 Furthermore, we detected partial reversibility of cadmium inhibition for all p53 family members by EDTA. Cadmium 50-57 P53 Homo sapiens 77-80 26745097-4 2015 DOX and 2DG treatments resulted in altered radiation-induced expression levels of p53 and PTEN genes in T47D as well as SKBR3 cells. Doxorubicin 0-3 P53 Homo sapiens 82-85 25446071-8 2015 DTT was able to reverse cadmium inhibition only for p53 and p73. Cadmium 24-31 P53 Homo sapiens 52-55 25446071-10 2015 In summary, cadmium strongly inhibits p53, p63 and p73 DNA binding in vitro and in cells in comparison to nickel and cobalt.

Silybin 41-50 P53 Homo sapiens 139-142 26320467-0 2015 Treatment with a Small Synthetic Compound, KMU-193, induces Apoptosis in A549 Human Lung Carcinoma Cells through p53 Up-Regulation. kmu 43-46 P53 Homo sapiens 113-116 25921167-1 2015 OBJECTIVE: To assess associations between codon 72 polymorphisms (Pro or B and Arg or b alleles) of the TP53 gene and lung cancer risk among Bangladeshis. Arginine 79-82 P53 Homo sapiens 104-108 26434906-3 2015 The aim of the study was to elucidate the role of p53 in the induction of apoptosis by eugenol and capsaicin in a human gastric cancer cell line, AGS. Capsaicin 99-108 P53 Homo sapiens 50-53 26320467-9 2015 Collectively, these results for the first time demonstrate that KMU-193 has strong apoptotic effects on A549 cells and these are largely mediated through caspase-3- and p53-dependent pathways. kmu 64-67 P53 Homo sapiens 169-172 26434906-6 2015 RESULTS: In the presence of p53, capsaicin was a more potent pro-apoptotic agent than eugenol. Capsaicin 33-42 P53 Homo sapiens 28-31 26320432-1 2015 BACKGROUND: Earlier studies on the association between p53 codon 72 Arg>Pro polymorphism and cancer risk were inconclusive and conflicting for the Saudi population. Arginine 68-71 P53 Homo sapiens 55-58 26434906-7 2015 However, silencing of p53 significantly abrogated apoptosis induced by capsaicin but not that by eugenol. Capsaicin 71-80 P53 Homo sapiens 22-25 26700591-3 2015 Here, we show that a branched-chain C-20 polyunsaturated fatty acid, geranylgeranoic acid (GGA), induces upregulation of the cellular protein levels of TP53-induced glycolysis and apoptosis regulator (TIGAR) and synthesis of cytochrome c oxidase 2 (SCO2) in human hepatoma-derived HuH-7cells harboring the mutant TP53 gene, suggesting that GGA may shift an energetic state of the tumor cells from aerobic glycolysis to mitochondrial respiration. Carbon 36-37 P53 Homo sapiens 152-156 26320432-9 2015 CONCLUSIONS: The current meta-analysis suggests that the codon 72 Arg>Pro polymorphism of the p53 gene might not contribute to cancer susceptibility in Saudi population.

Doxorubicin 136-147 P53 Homo sapiens 65-68 26252178-4 2015 We show that the serine 20 phosphorylated form of p53 is present at the mitochondria and that the decrease of p53 mitochondrial level during late apoptosis correlates with a decrease of Ser-20 phosphorylation. Serine 17-23 P53 Homo sapiens 50-53 26252178-4 2015 We show that the serine 20 phosphorylated form of p53 is present at the mitochondria and that the decrease of p53 mitochondrial level during late apoptosis correlates with a decrease of Ser-20 phosphorylation. Serine 17-23 P53 Homo sapiens 110-113 26252178-4 2015 We show that the serine 20 phosphorylated form of p53 is present at the mitochondria and that the decrease of p53 mitochondrial level during late apoptosis correlates with a decrease of Ser-20 phosphorylation. Serine 186-189 P53 Homo sapiens 50-53 26252178-4 2015 We show that the serine 20 phosphorylated form of p53 is present at the mitochondria and that the decrease of p53 mitochondrial level during late apoptosis correlates with a decrease of Ser-20 phosphorylation. Serine 186-189 P53 Homo sapiens 110-113 26252178-7 2015 We propose here that the level of serine 20 phosphorylation is influential on p53 mitochondrial localization during late apoptosis.

Ibuprofen 67-76 P53 Homo sapiens 262-265 25789565-7 2015 Here, we show that p53 phosphorylation at Ser 33 contributes to H2O2-induced miR-200s transcription. Serine 42-45 P53 Homo sapiens 19-22 25789565-7 2015 Here, we show that p53 phosphorylation at Ser 33 contributes to H2O2-induced miR-200s transcription. Hydrogen Peroxide 64-68 P53 Homo sapiens 19-22 25789565-8 2015 In addition, we show that p38alpha can directly phosphorylate p53 at serine 33 upon H2O2 exposure.

Cisplatin 17-26 P53 Homo sapiens 69-72 26089934-11 2015 Taken together, these results suggest that apigenin ameliorates cisplatin-induced apoptosis through reduction of p53 activation and promotion of PI3K/Akt pathway in HK-2 cells. Cisplatin 64-73 P53 Homo sapiens 113-116 26333122-6 2015 The p53 protein was activated and phosphorylated at serines 15 and 392 and accumulated in the nucleus after 24 and 48 h.

Increased levels of phosphorylated Chk2 at threonine 68 were observed in the cytoplasmic fraction after 24 and 48 h of mitoxantrone treatment. Threonine 314-323 P53 Homo sapiens 4-7 26441204-6 2015 The changes in the levels of key proteins show that benfluron provoked activation of p53 and induced phosphorylation of p53 on serine 15 and serine 392.

Metformin 0-9 P53 Homo sapiens 71-74 25252686-4 2015 In this study, we show that virus-mediated ROS upregulation activates the protein kinase, ataxia telangiectasia mutated, which in turn phosphorylates serine 15 on p53. Serine 150-156 P53 Homo sapiens 163-166 25252686-6 2015 Rather p53 appears to be involved in suppressing intracellular ROS levels in astrocytes under oxidative stress.

Superoxides 94-104 P53 Homo sapiens 14-17 25262359-11 2015 Curcumin treatment also altered the expressions of apoptosis associated proteins NF-kappaB, p38 and p53. Curcumin 0-8 P53 Homo sapiens 100-103 25143433-4 2015 Cisplatin treatment elicited apoptosis, ATM phosphorylation, upregulation of p53, Noxa (PMAIP1), and PUMA (BBC3), and cleavage of caspase-9, -7, fodrin, and PARP-1 in MCF-7 cells. Cisplatin 0-9 P53 Homo sapiens 77-80 24975171-3 2015 Accumulation of Cu causes necrosis that looks to be facilitated by DNA damage, followed by activation of P53.

Fluorouracil 91-95 P53 Homo sapiens 228-231 25815376-1 2015 SIRT1 regulates p53 transcriptional activation in response to genotoxic insult by deacetylating key lysine residues. Lysine 100-106 P53 Homo sapiens 16-19 25384972-6 2015 The blockade of basal (adenosine-free) signaling from A2a inhibits protein kinase A (PKA) activity, thereby recruiting cytosolic p53, which opens the mitochondrial permeability transition pore and impairs mitochondrial respiration, resulting in apoptosis. Adenosine 23-32 P53 Homo sapiens 129-132 25738310-12 2015 Sorafenib suppressed p53 expression at both mRNA and protein levels, which might contribute to cell cycle arrest and sensitize tumor cells to irinotecan.

Paclitaxel 24-29 P53 Homo sapiens 283-286 25164962-4 2015 Sequential treatment of Taxol or cisplatin, followed by MK-2206, induced a synergistic inhibition of cell proliferation and effectively promoted cell death, either by inhibiting the phosphorylation of Akt and its downstream effectors 4E-BP1 and p70S6K in SKOV3 cells or by restoring p53 levels, which were downregulated after Taxol or cisplatin treatment, in ES2 cells. Cisplatin 33-42 P53 Homo sapiens 283-286 24986024-7 2015 The less effectiveness could be due to the induction of ROS and p53 by UVB because removing ROS by L-NAC (10 mm) in p53 null cells could lead to alternative splicing of hdm2 upon UVB irradiation. ros 56-59 P53 Homo sapiens 116-119 25436001-10 2015 The PDCD5 transfected cells showed higher sensitivity to cisplatin treatment than the HepG2-Neo cells, with a higher p53 protein expression level. Cisplatin 57-66 P53 Homo sapiens 117-120 26180584-6 2015 This decrease seemed to be the main signal responsible for maintaining the intracellular redox homeostasis hindering the activation of p53 induced by ROS, p38MAPK, and PKCdelta. ros 150-153 P53 Homo sapiens 135-138 25289524-8 2015 Parthenolide-treated cells showed up-regulation of p53, Bax, caspase-3, -6, and -3 genes and down-regulation of Bcl-2 gene (p <= 0.008). parthenolide 0-12 P53 Homo sapiens 51-54 25833236-2 2015 The present study investigated the anticancer effect of irinotecan on p53-negative Caco-2 and p53-positive CW2 human colorectal cancer cell lines.

Reactive Oxygen Species 144-147 P53 Homo sapiens 223-226 27012093-1 2015 Human endometrium-derived mesenchymal stem cells (hMESC) under the sublethal oxidative stress induced by H2O2 activate both p53/p21/Rb and p38MAPK/MAPKAPK-2 pathways that are responsible for the induction of hMESC premature senescence (Borodkina et al., 2014). Hydrogen Peroxide 105-109 P53 Homo sapiens 124-127 26021170-3 2015 We compared the effect of the NaBu treatment on the human cell line with different TP53 mutation profile, including: wild-type TP53, single nucleotide substitutions, and the complete absence of TP53 gene. sethoxydim 30-34 P53 Homo sapiens 83-87 26021170-3 2015 We compared the effect of the NaBu treatment on the human cell line with different TP53 mutation profile, including: wild-type TP53, single nucleotide substitutions, and the complete absence of TP53 gene. sethoxydim 30-34 P53 Homo sapiens 127-131 26021170-3 2015 We compared the effect of the NaBu treatment on the human cell line with different TP53 mutation profile, including: wild-type TP53, single nucleotide substitutions, and the complete absence of TP53 gene. sethoxydim 30-34 P53 Homo sapiens 127-131 26021170-4 2015 NaBu activated the TP53 protein via hyper acetylation at lysine residue K382, without significant changes in the level of protein expression. sethoxydim 0-4 P53 Homo sapiens 19-23 26021170-4 2015 NaBu activated the TP53 protein via hyper acetylation at lysine residue K382, without significant changes in the level of protein expression. Lysine 57-63 P53 Homo sapiens 19-23 26021170-5 2015 Western blotting demonstrated that the addition of NaBu triggers a significant increase in the p21/Waf1 protein level in both the TP53 wild-type cells and in the cells with single nucleotide substitutions in the domain responsible for the binding of TP53 protein to DNA. sethoxydim 51-55 P53 Homo sapiens 130-134 26021170-5 2015 Western blotting demonstrated that the addition of NaBu triggers a significant increase in the p21/Waf1 protein level in both the TP53 wild-type cells and in the cells with single nucleotide substitutions in the domain responsible for the binding of TP53 protein to DNA. sethoxydim 51-55 P53 Homo sapiens 250-254 26021170-8 2015 Overall, our results suggest that the NaBu-dependent induction of p21/Waf1 does require the presence of TP53 protein but unexpectedly it can occur regardless of mutational changes in the domain responsible for the TP53 binding to DNA. sethoxydim 38-42 P53 Homo sapiens 104-108 26021170-8 2015 Overall, our results suggest that the NaBu-dependent induction of p21/Waf1 does require the presence of TP53 protein but unexpectedly it can occur regardless of mutational changes in the domain responsible for the TP53 binding to DNA. sethoxydim 38-42 P53 Homo sapiens 214-218 26349243-3 2015 It has been suggested that DOX induces death of cancer cells via p53-dependent apoptosis, however, the information regarding the role of p73 protein, a member of p53 tumor suppressor family, is scanty. Doxorubicin 27-30 P53 Homo sapiens 65-68 25436977-6 2014 Resveratrol-induced gene expression, including transcription of the most up-regulated genes and pro-apoptotic p53-dependent genes, was not affected by culture pH changes. Resveratrol 0-11 P53 Homo sapiens 110-113 26021170-9 2015 One of the hypothetical explanations is that NaBu increases the level of TP53 acetylation, and the modified protein is able to establish a new network of protein-protein interactions or trigger some conformational changes affecting the TP53-dependent transcriptional machinery even when its DNA binding ability is impaired. sethoxydim 45-49 P53 Homo sapiens 73-77 26021170-9 2015 One of the hypothetical explanations is that NaBu increases the level of TP53 acetylation, and the modified protein is able to establish a new network of protein-protein interactions or trigger some conformational changes affecting the TP53-dependent transcriptional machinery even when its DNA binding ability is impaired. sethoxydim 45-49 P53 Homo sapiens 236-240 25179905-5 2014 Following 2-MeO-E2 treatment, only HCT116 (p53(+/+)) cells exhibited an enhancement in the levels of p53, p-p53 (Ser-15), p21(WAF1/CIP1), and Bax; however, the Bak level remained relatively constant in both cell types, and the Bcl-2 level decreased only in HCT116 (p53(+/+)) cells. Serine 113-116 P53 Homo sapiens 43-46 25521755-7 2014 Rg3 also decreased the expression of HDAC3 and increased the acetylation of p53 on lysine (k373/k382). Lysine 83-89 P53 Homo sapiens 76-79 25526208-6 2014 The p53 codon 72 Pro/Pro genotype was associated with a longer median PFS time of 30.3 months compared with 18.2 months for patients with Arg/Arg variants.

Carbon 94-100 P53 Homo sapiens 143-147 25531293-4 2014 X-ray and carbon-ion beam irradiations predominantly induced apoptosis of the p53+/+ cells but not the p53-/- cells. Carbon 10-16 P53 Homo sapiens 78-81 25531293-5 2014 In the p53-/- cells, carbon-ion beam irradiation, but not X-ray irradiation, markedly induced mitotic catastrophe that was associated with premature mitotic entry with harboring long-retained DSBs at 24 h post-irradiation. Carbon 21-27 P53 Homo sapiens 7-10 25531293-6 2014 CONCLUSIONS: Efficient induction of mitotic catastrophe in apoptosis-resistant p53-deficient cells implies a strong cancer cell-killing effect of carbon-ion beam irradiation that is independent of the p53 status, suggesting its biological advantage over X-ray treatment.

Cisplatin 102-111 P53 Homo sapiens 13-16 25311616-6 2014 Under these same conditions, we also found that resveratrol altered the phosphorylation of several proteins involved in various biological processes, most notably transcriptional modulators, represented by p53, FOXA1, and AATF. Resveratrol 48-59 P53 Homo sapiens 206-209 24313628-4 2014 We observed that p53 protein residue at Ser 15 was phosphorylated after cryopreservation. Serine 40-43 P53 Homo sapiens 17-20 25220870-13 2014 Combinational treatment with zerumbone and cisplatin significantly accelerated apoptosis and promoted p53 expression and ROS production in NSCLC cells, compared with each alone.

Reactive Oxygen Species 0-3 P53 Homo sapiens 80-83 25469035-10 2014 Our results showed that treatment with 17beta-estradiol and/or ER agonists in human LoVo colorectal cancer cells activated p53 and then up-regulated p21 and p27 protein levels, subsequently inhibiting the downstream target gene, cyclin D1, which regulates cell proliferation. Estradiol 39-55 P53 Homo sapiens 123-126 25469035-12 2014 These results demonstrate that 17beta-estradiol and/or ER agonists downregulate migration-related proteins through the p53 signaling pathway in human LoVo colorectal cancer cells.

Dexamethasone 118-131 P53 Homo sapiens 31-34 23727633-8 2014 Levels of the p53 deacetylase sirtuin 1 were lower in dexamethasone-treated cells compared with controls.

Glucose 38-45 P53 Homo sapiens 27-30 25221641-8 2014 Genetic silencing of either wild-type PTEN or p53 in WRO cells resulted in increased uptake of glucose, whereas the ectopic expression of PTEN in FTC133 cells resulted in diminished glucose uptake. Glucose 95-102 P53 Homo sapiens 46-49 25221641-11 2014 We propose that concurrent PTEN deficiency and mutant p53 leads to a glucose-addiction state that renders the cancer cell more sensitive to glucose restriction.

Curcumin 173-181 P53 Homo sapiens 97-100 24806432-4 2014 To further explore the potential mechanism, we showed that curcumin increased the phosphorylation of ERK1/2 but not p38 MAPK in a time-dependent manner, and induced protein expression of the tumor suppressors FOXO3a and p53 in a dose-dependent manner, which were not observed in the presence of PD98059, an inhibitor of ERK1/2. Curcumin 59-67 P53 Homo sapiens 220-223 24806432-5 2014 Furthermore, silencing of FOXO3a and p53 genes by siRNAs overcame the inhibitory effect of curcumin on cell proliferation.

Curcumin 87-95 P53 Homo sapiens 25-28 24806432-8 2014 Together, our studies show that curcumin inhibits growth and induces apoptosis of NPC cells through ERK1/2-mediated increase in the protein expression and interaction of p53 and FOXO3a.

Doxorubicin 107-110 P53 Homo sapiens 151-154 24525822-7 2014 Conversely, C33A cervical cancer cells containing mutant p53 co-treated with VOR and DOX did not exhibit Bad upregulation, acetylated p53 induction or consequent synergistic growth inhibition. Doxorubicin 85-88 P53 Homo sapiens 57-60 24525822-8 2014 Together, the synergistic growth inhibition of cervical cancer cell lines induced by co-treatment with VOR and DOX can be attributed to the upregulation of Bad, which is induced by acetylated p53. Doxorubicin 111-114 P53 Homo sapiens 192-195 24525822-9 2014 These results show for the first time that the acetylation of p53, rather than histones, is a mechanism for the synergistic growth inhibition induced by VOR and DOX co-treatments.

Acetylcarnitine 0-18 P53 Homo sapiens 121-124 24445528-9 2014 Phosphorylation of p53 at serine-15 and of Sp1 at serines appears to be involved. Serine 26-32 P53 Homo sapiens 19-22 24012657-5 2014 The beneficial effects of acetyl-L-carnitine may occur through amelioration of oxidative stress because it effectively decreases the levels of oxidative products and increases the activity of superoxide dismutase; this leads to a recovery in the suppressed activity of p53 caused oxidative stimuli, which in turn restores levels of insulin-like growth factor II, an important hormone for learning and memory. Acetylcarnitine 26-44 P53 Homo sapiens 269-272 24121312-0 2014 Correlation of (18)F-fluoromisonidazole PET findings with HIF-1alpha and p53 expressions in head and neck cancer: comparison with (18)F-FDG PET. fluoromisonidazole 21-39 P53 Homo sapiens 73-76 24173110-4 2014 Three SNPs in the p53 pathway were identified using the Sanger sequencing method from retrospectively collected paraffin-embedded biopsy specimens.

Doxorubicin 35-46 P53 Homo sapiens 28-31 24099794-1 2013 The successful clinical management of lung cancer is limited by frequent loss-of-function mutations in p53 which cooperates with chronic oxidant-stress induced adaptations in mercapturic acid pathway (MAP) which in turn regulates critical intracellular signaling cascades that determine therapeutic refractoriness.

Cisplatin 178-187 P53 Homo sapiens 154-158 23839309-4 2013 We also show that senescence is the major cellular response to cisplatin in wtp53 HNSCC cells and that cisplatin resistance in p53-null or -mutant TP53 cells is due to their lack of senescence. Cisplatin 63-72 P53 Homo sapiens 78-81 23839309-4 2013 We also show that senescence is the major cellular response to cisplatin in wtp53 HNSCC cells and that cisplatin resistance in p53-null or -mutant TP53 cells is due to their lack of senescence.

Cisplatin 99-108 P53 Homo sapiens 27-30 23891087-8 2013 Loss of AMPK sensitized cells to the anti-proliferative effects of metformin, while loss of p53 promoted both the growth inhibitory and toxic effects of metformin. Metformin 153-162 P53 Homo sapiens 92-95 24228232-3 2013 The aim of the present study was to evaluate whether zinc dichloride (ZnCl2), which was known to re-establish the chemosensitivity of cancer cells by reactivating p53, promotes immunogenic instances of cell death. zinc chloride 53-68 P53 Homo sapiens 163-166 24228232-3 2013 The aim of the present study was to evaluate whether zinc dichloride (ZnCl2), which was known to re-establish the chemosensitivity of cancer cells by reactivating p53, promotes immunogenic instances of cell death. zinc chloride 70-75 P53 Homo sapiens 163-166 23670255-2 2013 Previously, we identified GADD153 as a target of BRCA1 protein, which increases doxorubicin sensitivity in human p53 -/- PCa cells (PC3).

Resveratrol 17-28 P53 Homo sapiens 231-234 23891087-0 2013 Contributions of AMPK and p53 dependent signaling to radiation response in the presence of metformin. Metformin 91-100 P53 Homo sapiens 26-29 23891087-10 2013 CONCLUSIONS: The anti-proliferative activity of metformin may confer benefit in combination with radiotherapy, and this benefit is intensified upon loss of AMPK or p53 signaling. Metformin 48-57 P53 Homo sapiens 164-167 23891087-2 2013 Metformin activates AMPK that in turn can launch a p53-dependent metabolic checkpoint. Metformin 0-9 P53 Homo sapiens 51-54 23891087-4 2013 Since radiation-induced signaling also involves AMPK and p53, we investigated their importance in mediating responses to metformin and radiation. Metformin 121-130 P53 Homo sapiens 57-60 23843462-7 2013 The activated AKT phosphorylated MDM2 at Ser(166) and promoted degradation of the tumor suppressor p53. Serine 41-44 P53 Homo sapiens 99-102 23976973-3 2013 Here we have shown that in cancer cells treated with anti-neoplastic drug GaQ3, p53, there is an increase in intracellular calcium levels by transcriptional regulation of a novel calcium channel gene TRPC6.

Cisplatin 0-9 P53 Homo sapiens 51-54 23680455-3 2013 In normal conditions, ROS have an important role in signal transduction and gene transcription, nevertheless, ROS may act as a trigger for carcinogenesis via persistent DNA injuries as well as mutations in p53 such as conditions observed in skin, hepatocellular, and colon cancers. Reactive Oxygen Species 22-25 P53 Homo sapiens 206-209 23845906-3 2013 Here, we found that cisplatin mainly induced non-apoptotic death of the pancreatic cancer cells (AsPC-1 and Capan-2), which was associated with a significant p53 activation (phosphorylation and accumulation). Cisplatin 20-29 P53 Homo sapiens 158-161 23845906-11 2013 Together, these data suggested that cisplatin-induced non-apoptotic death requires mitochondria Cyp-D-p53 signaling in pancreatic cancer cells. Cisplatin 36-45 P53 Homo sapiens 102-105 23845906-5 2013 We provided evidences to support that mitochondrial Cyp-D/p53 complexation might be critical for cisplatin-induced non-apoptotic death of pancreatic cancer cells. Cisplatin 97-106 P53 Homo sapiens 58-61 23845906-7 2013 Both CsA and Cyp-D knockdown also disrupted the Cyp-D/p53 complex formation in mitochondria. Cyclosporine 5-8 P53 Homo sapiens 54-57 23845906-8 2013 Meanwhile, the pancreatic cancer cells with p53 knockdown were resistant to cisplatin.

Cyclotides 14-23 P53 Homo sapiens 169-172 23848581-6 2013 The resulting cyclotide MCo-PMI was able to bind with low nanomolar affinity to both Hdm2 and HdmX, showed high stability in human serum, and was cytotoxic to wild-type p53 cancer cell lines by activating the p53 tumor suppressor pathway both in vitro and in vivo. Cyclotides 14-23 P53 Homo sapiens 209-212 23950944-6 2013 Moreover, p53 activator doxorubicin significantly enhanced GR 1-9/10 promoter activity in HepG2 cells at 100 nM, which was associated with significantly higher protein content of p53 and GR.

Alanine 84-91 P53 Homo sapiens 45-50 23652278-10 2013 Ser-15 of p53 was phosphorylated after 24 h of treatment of the cancer cells with OSU-03012. Serine 0-3 P53 Homo sapiens 10-13 23898080-9 2013 Parthenolide markedly reduced the constitutive and doxorubicin-induced NF-kappaB activity measured as the nuclear NF-kappaB, and expression of matrix metalloproteinase-9 (MMP9) and it had no effect on p53. parthenolide 0-12 P53 Homo sapiens 201-204 23898080-9 2013 Parthenolide markedly reduced the constitutive and doxorubicin-induced NF-kappaB activity measured as the nuclear NF-kappaB, and expression of matrix metalloproteinase-9 (MMP9) and it had no effect on p53. Doxorubicin 51-62 P53 Homo sapiens 201-204 23859017-4 2013 Cytotoxic concentrations of the nitric oxide donor sodium nitroprusside activated several proapoptotic mechanisms, including stimulation of the stress kinase pathways mediated by c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK), inhibition of the translation initiation factor eIF2alpha, induction and phosphorylation of the p53 protein, and inhibited Akt-mediated antiapoptotic signaling, independent of Ras function. Nitric Oxide 32-44 P53 Homo sapiens 354-357 24074787-8 2013 We reported that TP53 mutated non inflammatory locally advanced breast carcinomas had a high rate of complete pathological response to dose-dense doxorubicin-cyclophosphamide chemotherapy, while TP53 wild-type (WT) tumors never achieved complete response. Doxorubicin 146-157 P53 Homo sapiens 17-21 23725219-7 2013 Additionally, functional silencing of MIR21 and MIR30D in L428 cells showed increased sensitivity to doxorubicin-induced apoptosis, pointing towards abnormalities of mitochondrial intrinsic and TP53-CDKN1A pathways as related to miRNA deregulation in cHL. Doxorubicin 101-112 P53 Homo sapiens 194-198 24074787-10 2013 A recent work confirmed these findings in MMTV-Wnt1 mammary tumors, showing that growth arrest and senescent phenotype, not apoptosis, were induced in TP53 WT tumors following doxorubicin treatment, while lack of arrest in mutant tumors resulted in aberrant mitoses, cell death and a superior clinical response. Doxorubicin 176-187 P53 Homo sapiens 151-155 24074787-12 2013 Taken together, these data can help to better understand p53-mediated response to doxorubicin-based chemotherapy in breast cancer: in ER(+) TP53 WT breast cancers, ER-induced inhibition of p53 apoptotic response would lead preferentially to tumor cell senescence and subsequent resistance to treatment. Doxorubicin 82-93 P53 Homo sapiens 57-60 24074787-12 2013 Taken together, these data can help to better understand p53-mediated response to doxorubicin-based chemotherapy in breast cancer: in ER(+) TP53 WT breast cancers, ER-induced inhibition of p53 apoptotic response would lead preferentially to tumor cell senescence and subsequent resistance to treatment. Doxorubicin 82-93 P53 Homo sapiens 140-144 24074787-12 2013 Taken together, these data can help to better understand p53-mediated response to doxorubicin-based chemotherapy in breast cancer: in ER(+) TP53 WT breast cancers, ER-induced inhibition of p53 apoptotic response would lead preferentially to tumor cell senescence and subsequent resistance to treatment.

Doxorubicin 17-28 P53 Homo sapiens 67-70 23495037-4 2013 Blockade of cyclooxygenase-2 (COX-2) activity by siRNA or NS398 correspondingly inhibited ceramide-induced p53 Ser-15 phosphorylation and apoptosis; thus COX-2 appears at the apex of the p38 kinase-mediated signaling cascade induced by ceramide. Serine 111-114 P53 Homo sapiens 107-110 23495037-8 2013 In summary, resveratrol and ceramide converge on an endocytosis-requiring, ERK1/2-dependent signal transduction pathway and induction of COX-expression as an essential molecular antecedent for subsequent p53-dependent apoptosis. Resveratrol 12-23 P53 Homo sapiens 204-207 24009628-1 2013 BACKGROUND: Silent mating type information regulation 2 homolog 1 (SIRT1), an NAD+-dependent deacetylase, might act as a tumor promoter by inhibiting p53, but may also as a tumor suppressor by inhibiting several oncogenes such as beta-catenin and survivin. NAD 78-81 P53 Homo sapiens 150-153 23677787-4 2013 We observed that TGEV infection decreased p300/CBP, downregulated MDM2 and promoted p53 phosphorylation at serines 15, 20 and 46, resulting in accumulation and activation of p53 in PK-15 cells. Serine 107-114 P53 Homo sapiens 84-87 23946688-0 2013 Mutant p53-Notch1 Signaling Axis Is Involved in Curcumin-Induced Apoptosis of Breast Cancer Cells. Curcumin 48-56 P53 Homo sapiens 7-10 23946688-3 2013 The present study aimed to determine whether the mutant p53 can be a potent transcriptional activator of the Notch1 in MDA-MB-231 cells, and explore the role of this mutant p53-Notch1 axis in curcumin-induced apoptosis.

Resveratrol 142-153 P53 Homo sapiens 34-37 23946688-8 2013 Moreover, curcumin-induced apoptosis was further enhanced by the knockdown of Notch1 or mutant p53, but it was decreased by the overexpression of active Notch1. Curcumin 10-18 P53 Homo sapiens 95-98 23946688-9 2013 Taken together, our results demonstrate, for the first time, that Notch1 is a transcriptional target of mutant p53 in breast cancer cells and suggest that the targeting of mutant p53 and/or Notch1 may be combined with a chemotherapeutic strategy to improve the response of breast cancer cells to curcumin. Curcumin 296-304 P53 Homo sapiens 111-114 23946688-9 2013 Taken together, our results demonstrate, for the first time, that Notch1 is a transcriptional target of mutant p53 in breast cancer cells and suggest that the targeting of mutant p53 and/or Notch1 may be combined with a chemotherapeutic strategy to improve the response of breast cancer cells to curcumin.

Arginine 85-88 P53 Homo sapiens 53-57 23649769-1 2013 The close relationship between aflatoxins and 249ser TP53 gene mutation (AGG to AGT, Arg to Ser) in hepatocellular carcinoma (HCC) makes this mutation an indirect indicator of dietary contamination with this toxin. Serine 92-95 P53 Homo sapiens 53-57 23649769-9 2013 TP53 exon 7 mutations, which are related to aflatoxins exposure, were found at 14.6% (249ser), 7.3% (250leu) and 2.4% (250ser) in 41 cases of HCC and 1.4% in 74 liver cirrhosis (without HCC) cases, suggesting a moderate dietary exposure to aflatoxins in the Espirito Santo State, Brazil. 249ser 86-92 P53 Homo sapiens 0-4 23666059-10 2013 Thus, the hyperactivation of p53 by nutlin-3a helps to preserve the replicative potential of cells exposed to resveratrol. Resveratrol 110-121 P53 Homo sapiens 29-32 23683469-5 2013 The p53 gene contains a single nucleotide polymorphism at codon 72 of exon 4 which encodes either proline (Pro) or arginine (Arg).

Cisplatin 110-119 P53 Homo sapiens 49-52 23612976-6 2013 Most of the effects of Wip1 may be attributed to its ability to dephosphorylate p53 at Ser(15) and to inhibit DNA damage response. Serine 87-90 P53 Homo sapiens 80-83 23612976-7 2013 However, we also uncover a regulatory pathway whereby suppression of p53 Ser(15) phosphorylation is associated with enhanced phosphorylation at Ser(46), increased p53 protein levels, and induction of Noxa expression.

Lysine 48-54 P53 Homo sapiens 110-113 23603988-2 2013 We recently demonstrated that through their physical interaction, cdk9 phosphorylates p53 on Ser-392, leading to p53 stability and accumulation. Serine 93-96 P53 Homo sapiens 86-89 23603988-2 2013 We recently demonstrated that through their physical interaction, cdk9 phosphorylates p53 on Ser-392, leading to p53 stability and accumulation.

Copper 8-14 P53 Homo sapiens 102-105 23354308-5 2013 DSF and copper-chelated DSF at concentrations of 50-200 microM induced the disappearance of wild-type p53, mutant p53, NF-kappaB subunit p50 and the ubiquitin-activating enzyme E1 (UBE1) in tumor cell lines. Copper 8-14 P53 Homo sapiens 114-117 23354312-2 2013 We have recently shown that melatonin induces p38-dependent phosphorylation of both p53 and histone H2AX. Melatonin 28-37 P53 Homo sapiens 84-87 23354312-4 2013 In addition, the inhibition of p38 activities impairs melatonin"s capability to induce a p53-dependent DNA damage response and thus its ability to maintain genome integrity. Melatonin 54-63 P53 Homo sapiens 89-92 23354312-5 2013 Since melatonin-induced p53 phosphorylation requires an intact p38 phosphorylation cascade and p38 can be activated by G proteins, we supposed that melatonin"s activities could be mediated by its G-protein-coupled membrane receptors, MT1 and MT2. Melatonin 6-15 P53 Homo sapiens 24-27 23354312-5 2013 Since melatonin-induced p53 phosphorylation requires an intact p38 phosphorylation cascade and p38 can be activated by G proteins, we supposed that melatonin"s activities could be mediated by its G-protein-coupled membrane receptors, MT1 and MT2.

Melatonin 78-87 P53 Homo sapiens 41-44 23483263-4 2013 The combined inhibition of the HDAC and SIRT1 deacetylases abolished the cAMP-mediated deacetylation of p53, implying that cAMP-mediated deacetylation of p53 is dependent on the activity of these two classes of histone deacetylases.

Cyclic AMP 104-108 P53 Homo sapiens 159-162 23299313-5 2013 We did not find evidence for a selection process involving generation of increased basal cAMP levels in BCP-ALL cells, but we demonstrate that paracrine signaling involving prostaglandin E2-induced cAMP generation has the potential to suppress p53 activation and cell death induction. Dinoprostone 173-189 P53 Homo sapiens 244-247 23299313-5 2013 We did not find evidence for a selection process involving generation of increased basal cAMP levels in BCP-ALL cells, but we demonstrate that paracrine signaling involving prostaglandin E2-induced cAMP generation has the potential to suppress p53 activation and cell death induction.

Arginine 72-75 P53 Homo sapiens 34-38 23808158-7 2013 Moreover, EGCG suppressed the high glucose-induced expression of c-fos, c-myc and p53. Glucose 35-42 P53 Homo sapiens 82-85 23360948-2 2013 The high dose of calcium in the system activates the nitric oxide synthase, synthesizing nitric oxide which then downregulates Mdm2 and influences drastically the p53-Mdm2 network regulation, lifting the system from a normal to a stressed state. Calcium 17-24 P53 Homo sapiens 163-166 23360948-2 2013 The high dose of calcium in the system activates the nitric oxide synthase, synthesizing nitric oxide which then downregulates Mdm2 and influences drastically the p53-Mdm2 network regulation, lifting the system from a normal to a stressed state. Nitric Oxide 53-65 P53 Homo sapiens 163-166 23360948-3 2013 The increase in calcium level switches the system to different states, as identified by the different behaviours of the p53 temporal dynamics, i.e. oscillation death to sustain the oscillation state via a mixed state of dampened and oscillation death states. Calcium 16-23 P53 Homo sapiens 120-123 22619007-6 2013 In addition, Silibinin caused an increase in p53 and p21 protein level as well as mRNA levels.

Folic Acid 50-60 P53 Homo sapiens 220-223 24280180-4 2013 A gene expression microarray screen followed by constraint-based modeling (CBM) predicting metabolic changes imposed by the transcriptomic changes suggested a role for p53 in enhancing gluconeogenesis (de novo synthesis of glucose). Glucose 223-230 P53 Homo sapiens 168-171 24280180-7 2013 CONCLUSIONS: These findings portray p53 as a novel regulator of glucose production. Glucose 64-71 P53 Homo sapiens 36-39 24280180-8 2013 By facilitating glucose export, p53 may prevent it from being shunted to pro-cancerous pathways such as glycolysis and the PPP.

Fatty Acids 205-215 P53 Homo sapiens 0-3 22861165-4 2013 RESULTS: We found that upon GSH shortage, induced either by its chemical depletion or by metabolic stress (i.e., fasting), p53 binds to the PPARGC1A promoter of both human and mouse genes, and this event is positively related to increased PGC-1alpha expression. Glutathione 28-31 P53 Homo sapiens 123-126 23201008-5 2013 Upon treatment with 5-Aza-CdR, ATM activation was clearly associated with P53 phosphorylation at Ser(15), which was directly responsible for 5-Aza-CdR modified P21(Waf1/Cip1) expression. Serine 97-100 P53 Homo sapiens 74-77 23448605-3 2013 The aim of our study was to detect the level of apoptosis, expression bcl-2 and p53, associated with the different doses of CsA.

Serine 80-83 P53 Homo sapiens 91-94 23201157-11 2013 Finally, co-immunoprecipitation studies suggested that Ser-106 phosphorylation of p53 decreases its interaction with MDM2 and prolongs the half-life of p53. Serine 55-58 P53 Homo sapiens 82-85 23201157-11 2013 Finally, co-immunoprecipitation studies suggested that Ser-106 phosphorylation of p53 decreases its interaction with MDM2 and prolongs the half-life of p53. Serine 55-58 P53 Homo sapiens 152-155 22955948-6 2013 IKK-beta and p85 S6K1 contributed to H(2)O(2)-induced phosphorylation of Mdm2 (S166) and p53 accumulation. Hydrogen Peroxide 37-45 P53 Homo sapiens 89-92 23036084-4 2013 Using quantitative RT-PCR analysis, we found that miR-34a was highly upregulated in the p53 wild-type A549 human lung cancer cell line when treated with the DNA damaging agent adriamycin (ADR), but not in the SBC-5 cells harboring mutated p53. Doxorubicin 176-186 P53 Homo sapiens 88-91 23306062-3 2013 Here, we show that E2F1 overexpression, due to p53 or p21 inactivation, promotes expression of human oncoprotein CIP2A, which in turn, by inhibiting PP2A activity, increases stabilizing serine 364 phosphorylation of E2F1. Serine 186-192 P53 Homo sapiens 47-50 22855178-3 2013 It has been shown that methylation of CpG dinucleotides located in the promoter region of p53 is associated with low expression levels of this gene. cytidylyl-3'-5'-guanosine 38-55 P53 Homo sapiens 90-93 23076534-6 2013 Periostin-overexpressing cells treated with cisplatin or 5-FU showed significantly (p < 0.05) decreased expression of Bax and p53 proteins and increased expression of Bcl-2 protein, when compared to drug-treated mock counterparts.

Glucose 48-55 P53 Homo sapiens 33-36 23151455-3 2012 We report here that glucose restriction (GR) induces p53 mutant deacetylation, routing it for degradation via autophagy. Glucose 20-27 P53 Homo sapiens 53-56 23151455-5 2012 Furthermore, we found that a carbohydrate-free dietetic regimen that lowers the fasting glucose levels blunts p53 mutant expression and oncogenic activity relative to a normal diet in several animal model systems.

Galactose 54-65 P53 Homo sapiens 144-147 23192191-6 2012 Besides, the binding of pyrene derivatives to p53 DNA is stronger than that for C-myc DNA. pyrene 24-30 P53 Homo sapiens 46-49 23203124-8 2012 This impairment of p53 suppressed the hydrogen peroxide-induced apoptotic response in hepatocytes.

Calcium 297-304 P53 Homo sapiens 97-101 22583696-9 2012 Since H4 and p53 both contain the target lysine in an unstructured part of the protein, we conclude that the long recognition sequence of SET8 makes it difficult to methylate a lysine in a folded region of a protein, because amino acid side chains essential for recognition will be buried.

Doxorubicin 113-123 P53 Homo sapiens 231-234 22951418-7 2012 Inactivation of p53 impairs aerobic mitochondrial functions and causes greater dependence on anaerobic glycolysis, elevates lactate levels, reduces mitochondrial density in skeletal muscle and reduces endurance during physical exercise. Lactic Acid 124-131 P53 Homo sapiens 16-19 23146670-5 2012 Whereas doxorubicin treatment in early-passaged cells results in nucleosome density changes near the p53 binding sites of the p21 promoter, our studies show that senescent cells with a high p21 transcription activity had a comparable nucleosome distribution as unstressed young cells.

Cadmium 48-55 P53 Homo sapiens 143-146 21605570-8 2012 Here, a direct involvement of p53 was only observed with respect to APE1 gene expression contributing to an altered APE activity, while OGG activity was presumably affected indirectly due to a stronger accumulation of cadmium in HCT116 p53(+/+) cells. Cadmium 218-225 P53 Homo sapiens 236-239 21605570-5 2012 Therefore, this study was accomplished to investigate whether p53 is involved in the cadmium-induced inhibition of BER activity.

Cisplatin 23-27 P53 Homo sapiens 44-47 22223356-7 2012 MCF-10A cells morphologically transformed by long-term exposure to AlCl(3) display strong upregulation of the p53/p21(Waf1) pathway, a key mediator of growth arrest and senescence. Aluminum Chloride 67-74 P53 Homo sapiens 110-113 22223356-8 2012 These results suggest that aluminium is not generically mutagenic, but similar to an activated oncogene, it induces proliferation stress, DSBs and senescence in normal mammary epithelial cells; and that long-term exposure to AlCl(3) generates and selects for cells able to bypass p53/p21(Waf1) -mediated cellular senescence. Aluminum Chloride 225-232 P53 Homo sapiens 280-283 22357201-2 2012 Among TP53 gene polymorphisms, the most studied is the G to C transversion in exon 4 at codon 72, which results in three distinct genotypes, Arg/Arg, Pro/Pro and Arg/Pro, each one encoding different p53 isoforms.

RITA 10-14 P53 Homo sapiens 48-51 22037227-1 2012 BACKGROUND & AIMS: In this study we aimed at characterizing the regulation of hepatic metabolic pathways by the p53 transcription factor. Adenosine Monophosphate 12-15 P53 Homo sapiens 116-119 22071594-3 2012 Following metabolic activation, aristolochic acid reacts with genomic DNA to form aristolactam-DNA adducts that generate a unique TP53 mutational spectrum in the urothelium. aristolochic acid I 32-49 P53 Homo sapiens 130-134 22265823-5 2012 We further demonstrated that puerarin protected against MPP(+)-induced p53 nuclear accumulation, Puma (p53-upregulated mediator of apoptosis) and Bax expression and caspase-3-dependent programmed cell death (PCD). puerarin 29-37 P53 Homo sapiens 71-74 22265823-5 2012 We further demonstrated that puerarin protected against MPP(+)-induced p53 nuclear accumulation, Puma (p53-upregulated mediator of apoptosis) and Bax expression and caspase-3-dependent programmed cell death (PCD). puerarin 29-37 P53 Homo sapiens 103-106 22265823-8 2012 Collectively, these data suggest that the activation of PI3K/Akt pathway is involved in the protective effect of puerarin against MPP(+)-induced neuroblastoma SH-SY5Y cell death through inhibiting nuclear p53 accumulation and subsequently caspase-3-dependent PCD. puerarin 113-121 P53 Homo sapiens 205-208 22301190-2 2012 Moreover, p53 regulates glucose metabolism and its mutation results in the metabolic switch to the Warburg effect found in cancer cells. Glucose 24-31 P53 Homo sapiens 10-13 22172427-5 2012 Furthermore, PGG suppressed PARP cleavage and caspase-3 activation, cytochrome c release, up-regulation of bax and p53 in cisplatin-treated HRCs. Cisplatin 122-131 P53 Homo sapiens 115-118 22301190-5 2012 Here we demonstrated that p53-inducible microRNA-34a (miR-34a) repressed inosine 5"-monophosphate dehydrogenase (IMPDH), a rate-limiting enzyme of de novo GTP biosynthesis. Guanosine Triphosphate 155-158 P53 Homo sapiens 26-29 22290291-6 2012 Through endoplasmic reticulum (ER) stress, DIM stimulated the activation of p53 via Ser-15 phosphorylation, leading to increased expression of the BH3-only proapoptotic Bcl-2 members Puma and Noxa. Serine 84-87 P53 Homo sapiens 76-79 22250642-6 2012 Further studies performed in the cells with wt p53 status show differences between cisplatin and C1 at the level of cell cycle regulation. Cisplatin 83-92 P53 Homo sapiens 47-50 22184616-0 2012 Regulation of monocarboxylate transporter MCT1 expression by p53 mediates inward and outward lactate fluxes in tumors. Lactic Acid 93-100 P53 Homo sapiens 61-64 22184616-4 2012 Under hypoxic conditions, p53 loss promoted MCT1 expression and lactate export produced by elevated glycolytic flux, both in vitro and in vivo. Lactic Acid 64-71 P53 Homo sapiens 26-29 22184616-7 2012 Following glucose deprivation, upregulated MCT1 in p53(-/-) cells promoted lactate import and favored cell proliferation by fuelling mitochondrial respiration. Lactic Acid 75-82 P53 Homo sapiens 51-54 22184616-9 2012 Together, our findings identify MCT1 as a target for p53 repression and they suggest that MCT1 elevation in p53-deficient tumors allows them to adapt to metabolic needs by facilitating lactate export or import depending on the glucose availability. Lactic Acid 185-192 P53 Homo sapiens 53-56 22184616-9 2012 Together, our findings identify MCT1 as a target for p53 repression and they suggest that MCT1 elevation in p53-deficient tumors allows them to adapt to metabolic needs by facilitating lactate export or import depending on the glucose availability. Lactic Acid 185-192 P53 Homo sapiens 108-111 22184616-9 2012 Together, our findings identify MCT1 as a target for p53 repression and they suggest that MCT1 elevation in p53-deficient tumors allows them to adapt to metabolic needs by facilitating lactate export or import depending on the glucose availability. Glucose 227-234 P53 Homo sapiens 53-56 22184616-9 2012 Together, our findings identify MCT1 as a target for p53 repression and they suggest that MCT1 elevation in p53-deficient tumors allows them to adapt to metabolic needs by facilitating lactate export or import depending on the glucose availability. Glucose 227-234 P53 Homo sapiens 108-111 22117079-11 2012 The data presented here implicate the regulation of p53 subcellular localization and apoptosis by PARC as a contributing factor in CDDP resistance in OVCA cells and Ca(2+)/calpain in PARC post-translational processing and chemosensitivity. Cisplatin 131-135 P53 Homo sapiens 52-55 22117079-1 2012 Resistance to cisplatin (CDDP)-based therapy is a major hurdle to the successful treatment of human ovarian cancer (OVCA), and the chemoresistant phenotype in OVCA cells is associated with Akt-attenuated p53-mediated apoptosis. Cisplatin 14-23 P53 Homo sapiens 204-207 22305266-11 2012 More, we present evidence that over-expression of p53 or p53/p65 in the PANC1 cells were more sensitive to DOX treatment, correlated with activation of caspase-3 and clear elevation of nuclear p21 level. Doxorubicin 107-110 P53 Homo sapiens 50-53 22117079-1 2012 Resistance to cisplatin (CDDP)-based therapy is a major hurdle to the successful treatment of human ovarian cancer (OVCA), and the chemoresistant phenotype in OVCA cells is associated with Akt-attenuated p53-mediated apoptosis. Cisplatin 25-29 P53 Homo sapiens 204-207 22117079-6 2012 Here, we present evidence that CDDP promotes calpain-mediated PARC down-regulation, mitochondrial and nuclear p53 accumulation, and apoptosis in chemosensitive but not resistant OVCA cells. Cisplatin 31-35 P53 Homo sapiens 110-113 22117079-7 2012 Inhibition of Akt is required to sensitize chemoresistant cells to CDDP in a p53-dependent manner, an effect enhanced by PARC down-regulation. Cisplatin 67-71 P53 Homo sapiens 77-80 22305266-11 2012 More, we present evidence that over-expression of p53 or p53/p65 in the PANC1 cells were more sensitive to DOX treatment, correlated with activation of caspase-3 and clear elevation of nuclear p21 level. Doxorubicin 107-110 P53 Homo sapiens 57-60 22305266-13 2012 The present findings here reinforced this idea by showing p21"s ability of potentiality of DOX-induced cell death correlated with its inhibition of cell cycle progression after over-expression of p53 or p53/p65. Doxorubicin 91-94 P53 Homo sapiens 196-199 22305266-13 2012 The present findings here reinforced this idea by showing p21"s ability of potentiality of DOX-induced cell death correlated with its inhibition of cell cycle progression after over-expression of p53 or p53/p65. Doxorubicin 91-94 P53 Homo sapiens 203-206 22305266-14 2012 CONCLUSION: Our data suggested p65 could increase p53-mediated cell death in response to DOX in PANC1 cells. Doxorubicin 89-92 P53 Homo sapiens 50-53 21983885-0 2012 Role and interaction of p53, BAX and the stress-activated protein kinases p38 and JNK in benzo(a)pyrene-diolepoxide induced apoptosis in human colon carcinoma cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 89-115 P53 Homo sapiens 24-27 22002102-6 2012 Wild type p53 function inhibits the efficacy of a combined IR and ABT-737 treatment via a p21-dependent G1 cell cycle arrest. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 66-69 P53 Homo sapiens 10-13 22002102-7 2012 Moreover, mutant as well as wild type p53 counteract the pro-apoptotic activity of ABT-737 by maintaining the expression levels of the Mcl-1 protein. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 83-86 P53 Homo sapiens 38-41 22002102-8 2012 Thus, p53 regulates the sensitivity to ABT-737 of glioblastoma cells. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid 39-42 P53 Homo sapiens 6-9 22179573-3 2012 The resulting pyr-dba functioned as the enone analogs of curcumin and efficiently inhibited the activation of NF-kappaB and the growth of colorectal carcinoma HCT116 p53+/+ cells as well as the HIV-1 IN-LEDGF/p75 interaction. pyr-dba 14-21 P53 Homo sapiens 166-169 22179573-3 2012 The resulting pyr-dba functioned as the enone analogs of curcumin and efficiently inhibited the activation of NF-kappaB and the growth of colorectal carcinoma HCT116 p53+/+ cells as well as the HIV-1 IN-LEDGF/p75 interaction. enone 40-45 P53 Homo sapiens 166-169 22179573-3 2012 The resulting pyr-dba functioned as the enone analogs of curcumin and efficiently inhibited the activation of NF-kappaB and the growth of colorectal carcinoma HCT116 p53+/+ cells as well as the HIV-1 IN-LEDGF/p75 interaction. Curcumin 57-65 P53 Homo sapiens 166-169 21983885-11 2012 As reported previously, we could reconfirm a critical role of p53 in BPDE-induced apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 69-73 P53 Homo sapiens 62-65 21983885-12 2012 Furthermore, induced levels of total p53 and its transcriptional target p21 declined at higher BPDE concentrations correlating with reduced rates of apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 95-99 P53 Homo sapiens 37-40 21983885-13 2012 Interestingly, increased phosphorylation of p53 at serine 15 remained elevated at higher BPDE concentrations thus disconnecting p53 phosphorylation from downstream apoptosis. Serine 51-57 P53 Homo sapiens 44-47 21983885-13 2012 Interestingly, increased phosphorylation of p53 at serine 15 remained elevated at higher BPDE concentrations thus disconnecting p53 phosphorylation from downstream apoptosis. Serine 51-57 P53 Homo sapiens 128-131 21983885-13 2012 Interestingly, increased phosphorylation of p53 at serine 15 remained elevated at higher BPDE concentrations thus disconnecting p53 phosphorylation from downstream apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 89-93 P53 Homo sapiens 44-47 21983885-13 2012 Interestingly, increased phosphorylation of p53 at serine 15 remained elevated at higher BPDE concentrations thus disconnecting p53 phosphorylation from downstream apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 89-93 P53 Homo sapiens 128-131 21983885-14 2012 Hence, phosphorylation of p53 seems not only to be a more sensitive biomarker of BPDE exposure but might serve other functions unrelated to apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 81-85 P53 Homo sapiens 26-29 22114073-3 2012 Exposure of human prostate cancer LNCaP cells (harboring wild-type p53) and PC-3 cells (lacking p53) with 10-80 mug/ml of GTP for 24 h resulted in dose-dependent inhibition of class I HDAC enzyme activity and its protein expression. Guanosine Triphosphate 122-125 P53 Homo sapiens 67-70 22114073-3 2012 Exposure of human prostate cancer LNCaP cells (harboring wild-type p53) and PC-3 cells (lacking p53) with 10-80 mug/ml of GTP for 24 h resulted in dose-dependent inhibition of class I HDAC enzyme activity and its protein expression. Guanosine Triphosphate 122-125 P53 Homo sapiens 96-99 22085531-8 2012 Importantly, the ROS scavenger N-acetylcysteine (NAC) could inhibited LPS-induced autophagy and knockdown of p8 by RNA interference inhibited the autophagy, p53 protein level increase, the translocation of p53 into nuclei and the ROS level increase induced by LPS in HUVECs. Acetylcysteine 49-52 P53 Homo sapiens 157-160 22593641-10 2012 Upregulation of proline dehydrogenase by the tumor suppressor, p53, leads to enhanced mitochondrial reactive oxygen species that induce the intrinsic apoptotic pathway. Reactive Oxygen Species 100-123 P53 Homo sapiens 63-66 22112863-6 2012 Upon treatment with depsipeptide, p53 phosphorylation at threonine 18 (Thr18) was specifically induced. Threonine 57-66 P53 Homo sapiens 34-37 22112863-6 2012 Upon treatment with depsipeptide, p53 phosphorylation at threonine 18 (Thr18) was specifically induced. UNII-PYZ33YLR8A 71-76 P53 Homo sapiens 34-37 22112863-7 2012 Furthermore, we also demonstrated that phosphorylation of p53 at Thr18 is required for p53 acetylation at lysine 373/382 and for p21 expression in response to depsipeptide treatment.

Lysine 106-112 P53 Homo sapiens 87-90 22112863-8 2012 Our results demonstrate that depsipeptide plays an anti-neoplastic role by generating ROS to elicit p53/p21 pathway activation. Reactive Oxygen Species 86-89 P53 Homo sapiens 100-103 22093905-5 2012 Interestingly, human p53 induces cell death in recombinant strains Mut(s) with characteristic markers of apoptosis such as DNA fragmentation, exposure of phosphatidylserine, and reactive oxygen species generation.

Cisplatin 16-25 P53 Homo sapiens 70-73 22778941-2 2012 Cisplatin forms inter- and intrastrand crosslinked DNA adducts and its cytotoxicity is mediated by propagation of DNA damage recognition signals to downstream pathways involving ATR, p53, p73, and mitogen-activated protein kinases, ultimately resulting in apoptosis. Cisplatin 0-9 P53 Homo sapiens 183-186 23113120-8 2012 A positive correlation was found between survivin level and total human p53 level in children with ALL (r=0.501 & P<0.0001). Adenosine Monophosphate 113-116 P53 Homo sapiens 72-75 22583615-5 2012 Ataxia telangiectasia mutated protein kinase (ATM) was activated by GL331 through its autophosphorylation at Ser1981, which led to the activation of DNA damage signaling pathways including p53/p21 and Chk2/Cdc25A cascades. GL 331 68-73 P53 Homo sapiens 189-192 22466960-8 2012 Interruption of ERK and p53 activities decreased SU11274-induced autophagy, and blocking of ERK by the specific inhibitor PD98059 suppressed SU11274-induced p53 activation. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 122-129 P53 Homo sapiens 157-160 23038158-10 2012 The risk of p53 mutation was also higher in participants with APE1 Asp/Asp plus hOGG1-Cys than in those with APE1-Glu plus hOGG1 Ser/Ser (OR, 3.72; 95% CI, 1.33-10.40; P = 0.012). Serine 133-136 P53 Homo sapiens 12-15 23038158-11 2012 CONCLUSIONS: These results suggest that the APE1 Asp/Asp genotype and the combination of the APE1 Asp/Asp and hOGG1-Cys variants are associated with increased risk of p53 mutation in non-small cell lung cancer. Cysteine 116-119 P53 Homo sapiens 167-170 22124122-6 2012 Wnt5a and calcium ionophore activate NFATc1, NFATc2, NF-kappaB, and B cell lymphoma 6 (BCL-6) promptly and upregulate CD40 expression in GC B and Ramos cells, whereas p53 and JNK are not upregulated or activated. Calcium 10-17 P53 Homo sapiens 167-170 23216635-0 2012 Reactive oxygen species mediate Cr(VI)-induced S phase arrest through p53 in human colon cancer cells. Reactive Oxygen Species 0-23 P53 Homo sapiens 70-73 23038158-0 2012 The APE1 Asp/Asp genotype and the combination of APE1 Asp/Asp and hOGG1-Cys variants are associated with increased p53 mutation in non-small cell lung cancer. Cysteine 72-75 P53 Homo sapiens 115-118 23038158-9 2012 However, a higher risk of p53 mutation was found in participants with the APE1 Asp/Asp genotype than in those with the APE1-Glu allele (OR, 2.15; 95% CI, 1.19-3.87; P = 0.011). Glutamic Acid 124-127 P53 Homo sapiens 26-29 23038158-10 2012 The risk of p53 mutation was also higher in participants with APE1 Asp/Asp plus hOGG1-Cys than in those with APE1-Glu plus hOGG1 Ser/Ser (OR, 3.72; 95% CI, 1.33-10.40; P = 0.012). Cysteine 86-89 P53 Homo sapiens 12-15 23038158-10 2012 The risk of p53 mutation was also higher in participants with APE1 Asp/Asp plus hOGG1-Cys than in those with APE1-Glu plus hOGG1 Ser/Ser (OR, 3.72; 95% CI, 1.33-10.40; P = 0.012). Glutamic Acid 114-117 P53 Homo sapiens 12-15 23038158-10 2012 The risk of p53 mutation was also higher in participants with APE1 Asp/Asp plus hOGG1-Cys than in those with APE1-Glu plus hOGG1 Ser/Ser (OR, 3.72; 95% CI, 1.33-10.40; P = 0.012). Serine 129-132 P53 Homo sapiens 12-15 21964832-12 2012 Taken together, we suggest that BBR may be used as an effective ingredient for anticancer products, which trigger the transcriptional activity and the inhibition of the degradation of p53, a tumor suppressor gene, in human breast cancer. Berberine 32-35 P53 Homo sapiens 208-211 22613405-1 2012 OBJECTIVE: The association between codon 72 polymorphism of the tumour protein p53 (TP53) gene - which results in a missense mutation of arginine (R) to proline (P) - and susceptibility to hepatocellular carcinoma (HCC) is controversial. Arginine 137-145 P53 Homo sapiens 79-82 22613405-1 2012 OBJECTIVE: The association between codon 72 polymorphism of the tumour protein p53 (TP53) gene - which results in a missense mutation of arginine (R) to proline (P) - and susceptibility to hepatocellular carcinoma (HCC) is controversial. Arginine 137-145 P53 Homo sapiens 84-88 23936624-1 2012 A texaphyrin-oxaliplatin conjugate, oxaliTEX, was designed to test the concept that a platinum analog can overcome defects in drug accumulation and p53-dependent DNA damage response in a tumor model expressing multifactorial mechanisms of cisplatin resistance. Platinum 86-94 P53 Homo sapiens 148-151 23936624-3 2012 Unlike cisplatin, oxaliTEX accumulated and formed DNA adducts, stabilized and activated p53 at similar levels in both sensitive and resistant cells, and induced apoptosis in both models. oxalitex 18-26 P53 Homo sapiens 88-91 22876131-0 2012 Involvement of Smac, p53, and caspase pathways in induction of apoptosis by gossypol in human retinoblastoma cells. Gossypol 76-84 P53 Homo sapiens 21-24 21964832-0 2012 Effect of berberine on p53 expression by TPA in breast cancer cells. Berberine 10-19 P53 Homo sapiens 23-26 22760199-8 2012 Phospho-p53 and phospho-H2Ax Western blot indicate subsequent DNA damage as an important effector of doxorubicin-induced death. Doxorubicin 101-112 P53 Homo sapiens 8-11 22389628-4 2012 In response to retinoic acid, CBP/p300 acetylates p53 at lysine 373, which leads to dissociation from E3-ubiquitin ligases HDM2 and TRIM24. Tretinoin 15-28 P53 Homo sapiens 50-53 22589701-4 2012 The upregulation of NOX is also consistently observed in cancer cells with compromised mitochondria due to the activation of oncogenic Ras or loss of p53, and in primary pancreatic cancer tissues. nicotine 1-N-oxide 20-23 P53 Homo sapiens 150-153 22737085-5 2012 Foxa1-only sites are enriched for p53 binding sites and are frequently found near genes important to cell cycle regulation, while Foxa2-restricted sites show only a limited match to the forkhead consensus and are found in genes involved in steroid and lipid metabolism. Steroids 240-247 P53 Homo sapiens 34-37 23285001-6 2012 Furthermore, patients with high p53 expression in tumors acquired remarkable survival benefit from adjuvant first-line platinum-based-chemotherapy. Platinum 119-127 P53 Homo sapiens 32-35 23285001-8 2012 Thus, p53 expression is a potent prognostic and predictive factor for resectable gastric cancer with adjuvant platinum-based chemotherapy. Platinum 110-118 P53 Homo sapiens 6-9 23285096-4 2012 Here we investigated the mechanisms of GTP-induced apoptosis in human prostate cancer LNCaP cells stably-transfected with short hairpin-RNA against p53 (LNCaPshp53) and control vector (LNCaPshV). Guanosine Triphosphate 39-42 P53 Homo sapiens 148-151 23285096-5 2012 GTP treatment induced p53 stabilization and activation of downstream targets p21/waf1 and Bax in a dose-dependent manner specifically in LNCaPshV cells. Guanosine Triphosphate 0-3 P53 Homo sapiens 22-25 23259030-7 2012 Furthermore, EGCG was found to prevent serial passage- and H(2)O(2)-induced senescence in HDFs by suppressing p53 acetylation, but the Sirt1 activity was unaffected. Hydrogen Peroxide 59-67 P53 Homo sapiens 110-113 23300887-11 2012 Ser-15 of p53 was phosphorylated after 15 min treatment of the cancer cells with SDGE. Serine 0-3 P53 Homo sapiens 10-13 23300887-11 2012 Ser-15 of p53 was phosphorylated after 15 min treatment of the cancer cells with SDGE. sdge 81-85 P53 Homo sapiens 10-13 23300887-13 2012 Inhibitor of p53, pifithrin-alpha, attenuated the anti-cancer effects of SDGE and apoptosis was also not observed in the p53(neg) SKOV-3 cells. sdge 73-77 P53 Homo sapiens 13-16 23272171-0 2012 Dexamethasone reduces sensitivity to cisplatin by blunting p53-dependent cellular senescence in non-small cell lung cancer. Dexamethasone 0-13 P53 Homo sapiens 59-62 23272171-0 2012 Dexamethasone reduces sensitivity to cisplatin by blunting p53-dependent cellular senescence in non-small cell lung cancer. Cisplatin 37-46 P53 Homo sapiens 59-62 23272171-6 2012 DEX co-treatment cells exhibited the decrease of DNA damage signaling pathway proteins, the lower expression of p53 and p21(CIP1), the lower cellular secretory program and down-regulation of NF-kappaB and its signaling cascade. Dexamethasone 0-3 P53 Homo sapiens 112-115 23272171-8 2012 CONCLUSIONS: Our results underscore that DEX reduces chemotherapy sensitivity by blunting therapy induced cellular senescence after chemotherapy in NSCLC, which may, at least in part, in a p53-dependent manner. Dexamethasone 41-44 P53 Homo sapiens 189-192 22389628-4 2012 In response to retinoic acid, CBP/p300 acetylates p53 at lysine 373, which leads to dissociation from E3-ubiquitin ligases HDM2 and TRIM24. Lysine 57-63 P53 Homo sapiens 50-53 22389628-7 2012 Induction of p53 levels is a key step: RNA-interference-mediated knockdown of p53 delays differentiation, whereas depletion of negative regulators of p53 or ectopic expression of p53 yields spontaneous differentiation of hESCs, independently of retinoic acid. Tretinoin 245-258 P53 Homo sapiens 13-16 23152782-11 2012 Western blot analysis suggested that pretreatment with Ki-67-7 sensitized bladder cancer cells to curcumin-mediated apoptosis and cell cycle arrest by p53- and p21-independent mechanisms. Curcumin 98-106 P53 Homo sapiens 151-154 23152798-0 2012 Transient transfection of a wild-type p53 gene triggers resveratrol-induced apoptosis in cancer cells. Resveratrol 56-67 P53 Homo sapiens 38-41 23133614-8 2012 Moreover, the enhanced doxorubicin resistance is independent of DNA damage related p53 pathway, but at least partially through the ERK1/2 pathway. Doxorubicin 23-34 P53 Homo sapiens 83-86 23152798-2 2012 p53 has been suggested to play a role in the anticancer properties of resveratrol. Resveratrol 70-81 P53 Homo sapiens 0-3 23152798-3 2012 We investigated resveratrol-induced cytotoxicity in H1299 cells, which are non-small lung cancer cells that have a partial deletion of the gene that encodes the p53 protein. Resveratrol 16-27 P53 Homo sapiens 161-164 23152798-7 2012 Resveratrol also increased the p53 protein levels in MCF-7 cells without altering the p53 mRNA levels, suggesting a post-translational modulation of the protein. Resveratrol 0-11 P53 Homo sapiens 31-34 23152798-8 2012 The resveratrol-induced cytotoxicity in these cells was partially mediated by p53 and involved the activation of caspases 9 and 7 and the cleavage of PARP. Resveratrol 4-15 P53 Homo sapiens 78-81 23152798-11 2012 The transient transfection of a wild-type p53-GFP gene caused H1299 cells to become more responsive to the pro-apoptotic properties of resveratrol, similarly to findings in the p53-positive MCF-7 cells. Resveratrol 135-146 P53 Homo sapiens 42-45 23152798-12 2012 Our results suggest a possible therapeutic strategy based on the use of resveratrol for the treatment of tumors that are typically unresponsive to conventional therapies because of the loss of normal p53 function. Resveratrol 72-83 P53 Homo sapiens 200-203 23133524-0 2012 Gatifloxacin induces S and G2-phase cell cycle arrest in pancreatic cancer cells via p21/p27/p53. Gatifloxacin 0-12 P53 Homo sapiens 93-96 23133524-5 2012 However, Gatifloxacin mediated G(2)-phase cell cycle arrest was found to be p53 dependent in both the cell lines. Gatifloxacin 9-21 P53 Homo sapiens 76-79 23071787-6 2012 The frequency of somatic TP53 inactivation was 25.4% in Arg/Arg, 20.9% in Arg/Pro, and 16.7% in Pro/Pro patients, which may reflect a higher selective pressure to mutate the Arg-allele. Arginine 56-59 P53 Homo sapiens 25-29 23071787-6 2012 The frequency of somatic TP53 inactivation was 25.4% in Arg/Arg, 20.9% in Arg/Pro, and 16.7% in Pro/Pro patients, which may reflect a higher selective pressure to mutate the Arg-allele. Arginine 60-63 P53 Homo sapiens 25-29 23071787-6 2012 The frequency of somatic TP53 inactivation was 25.4% in Arg/Arg, 20.9% in Arg/Pro, and 16.7% in Pro/Pro patients, which may reflect a higher selective pressure to mutate the Arg-allele. Arginine 60-63 P53 Homo sapiens 25-29 23071787-6 2012 The frequency of somatic TP53 inactivation was 25.4% in Arg/Arg, 20.9% in Arg/Pro, and 16.7% in Pro/Pro patients, which may reflect a higher selective pressure to mutate the Arg-allele. Arginine 60-63 P53 Homo sapiens 25-29 23049825-3 2012 In this study we evaluate the association between a p53 variant functionally known to influence apoptosis (codon 72 Pro/Arg) and the subset of primary open angle glaucoma (POAG) patients with early loss of central visual field. Arginine 120-123 P53 Homo sapiens 52-55 23049825-4 2012 METHODS: Genotypes for the p53 codon 72 polymorphism (Pro/Arg) were obtained for 264 POAG patients and 400 controls from the U.S. and in replication studies for 308 POAG patients and 178 controls from Australia (GIST). Arginine 58-61 P53 Homo sapiens 27-30 23056530-1 2012 Current evidence suggests that ghrelin, a stomach derived peptide, exerts its orexigenic action through specific modulation of Sirtuin1 (SIRT1)/p53 and AMP-activated protein kinase (AMPK) pathways, which ultimately increase the expression of agouti-related protein (AgRP) and neuropeptide Y (NPY) in the arcuate nucleus of the hypothalamus (ARC). Ghrelin 31-38 P53 Homo sapiens 144-147 22911849-9 2012 Over-expression of the dominant negative p53 mutant DeltaTAp53, which inhibits p53 activity, prevented the TPA-induced K14 down-regulation in C9 cells. Tetradecanoylphorbol Acetate 107-110 P53 Homo sapiens 41-44 22905229-10 2012 Pharmacologic inhibition of the p53 E3 ligase MDM2 resulted in increased p53 levels and improved response to doxorubicin in vitro. Doxorubicin 109-120 P53 Homo sapiens 32-35 22911849-9 2012 Over-expression of the dominant negative p53 mutant DeltaTAp53, which inhibits p53 activity, prevented the TPA-induced K14 down-regulation in C9 cells. Tetradecanoylphorbol Acetate 107-110 P53 Homo sapiens 59-62 22911849-11 2012 Finally, we found that TPA induces the phosphorylation of p53 at residue 378, which enhances the affinity of p53 to bind to Sp1 and repress K14 expression. Tetradecanoylphorbol Acetate 23-26 P53 Homo sapiens 58-61 22911849-11 2012 Finally, we found that TPA induces the phosphorylation of p53 at residue 378, which enhances the affinity of p53 to bind to Sp1 and repress K14 expression. Tetradecanoylphorbol Acetate 23-26 P53 Homo sapiens 109-112 22859938-7 2012 We found p53 nuclear localization, activity, and phosphorylation at serine 15 on p53 increased during ER stress. Serine 68-74 P53 Homo sapiens 9-12 22848731-0 2012 An NQO1-initiated and p53-independent apoptotic pathway determines the anti-tumor effect of tanshinone IIA against non-small cell lung cancer. tanshinone 92-106 P53 Homo sapiens 22-25 22859938-7 2012 We found p53 nuclear localization, activity, and phosphorylation at serine 15 on p53 increased during ER stress. Serine 68-74 P53 Homo sapiens 81-84 22848731-8 2012 TSA activated a ROS triggered, p53 independent and caspase dependent mitochondria apoptotic cell death pathway that is characterized with increased ratio of Bax to Bcl-xl, mitochondrial membrane potential disruption, cytochrome c release, and subsequent caspase activation and PARP-1 cleavage. tanshinone 0-3 P53 Homo sapiens 31-34 22590594-2 2012 Deregulation of p53 and/or p73-associated apoptotic pathways contribute to the platinum-based resistance in ovarian cancer. Platinum 79-87 P53 Homo sapiens 16-19 22574148-5 2012 These results show an up-regulation of p53 phosphorylation at several serine sites after RVFV MP-12 infection that is highly dependent on the viral protein NSs. Serine 70-76 P53 Homo sapiens 39-42 22662219-9 2012 RITA induced p53 in GIST48B, followed by antiproliferative effects and a strong induction of apoptosis. RITA 0-4 P53 Homo sapiens 13-16 22590594-4 2012 In this study, we found that genetic variants of Bcl-2 proteins exist among cisplatin-sensitive and -resistant ovarian cancer cells, and the responses of NOXA and Bax to cisplatin are regulated mainly by p53. Cisplatin 170-179 P53 Homo sapiens 204-207 22514710-3 2012 The increase in SA-gal staining was preceded by increases in both p53 phosphorylation (S15) (1 h) and transactivation (6 h) and the abundance of the cyclin inhibitor p21(CIP1) (16 h). sa-gal 16-22 P53 Homo sapiens 66-69 22606351-6 2012 Since p53 and p16 are homozygously deleted in the K562 cells, the DOX-induced senescence in K562 cells ought to be independent of p53 and p16-pRb pathways. Doxorubicin 66-69 P53 Homo sapiens 6-9 22606351-6 2012 Since p53 and p16 are homozygously deleted in the K562 cells, the DOX-induced senescence in K562 cells ought to be independent of p53 and p16-pRb pathways. Doxorubicin 66-69 P53 Homo sapiens 130-133 22514710-9 2012 In conclusion, the results indicate that H(2)O(2) at low concentrations causes premature senescence in human keratinocytes by activating p53-p21(CIP1) signaling and that these effects can be prevented by acute AMPK activation and enhanced by AMPK downregulation. Hydrogen Peroxide 41-49 P53 Homo sapiens 137-140 22448262-0 2012 Cadmium induces p53-dependent apoptosis in human prostate epithelial cells. Cadmium 0-7 P53 Homo sapiens 16-19 22448262-6 2012 Subsequently, cellular response to cadmium was evaluated after siRNA-mediated p53 silencing in wild type p53-expressing RWPE-1 and LNCaP cells, and after adenoviral p53 overexpression in p53-deficient DU145 and PC-3 cell lines. Cadmium 35-42 P53 Homo sapiens 78-81 22448262-6 2012 Subsequently, cellular response to cadmium was evaluated after siRNA-mediated p53 silencing in wild type p53-expressing RWPE-1 and LNCaP cells, and after adenoviral p53 overexpression in p53-deficient DU145 and PC-3 cell lines.

Cadmium 35-42 P53 Homo sapiens 105-108 22448262-6 2012 Subsequently, cellular response to cadmium was evaluated after siRNA-mediated p53 silencing in wild type p53-expressing RWPE-1 and LNCaP cells, and after adenoviral p53 overexpression in p53-deficient DU145 and PC-3 cell lines. Cadmium 35-42 P53 Homo sapiens 105-108 22448262-8 2012 On the other hand, p53 silencing was able to suppress cadmium-induced apoptosis. Cadmium 54-61 P53 Homo sapiens 19-22 22448262-9 2012 Our results demonstrate that cadmium can induce p53-dependent apoptosis in human prostate epithelial cells and suggest p53 mutation as a possible contributing factor for the acquisition of apoptotic resistance in cadmium prostatic carcinogenesis. Cadmium 29-36 P53 Homo sapiens 48-51 22448262-9 2012 Our results demonstrate that cadmium can induce p53-dependent apoptosis in human prostate epithelial cells and suggest p53 mutation as a possible contributing factor for the acquisition of apoptotic resistance in cadmium prostatic carcinogenesis. Cadmium 213-220 P53 Homo sapiens 119-122 22242180-9 2012 Thus this study suggests that ROS/RNS contributed to change of p53 tertiary structure and that unfolded p53 can be considered as an early marker of oxidative imbalance in these patients. ros 30-33 P53 Homo sapiens 63-66 22412944-7 2012 In comparison with control groups, the levels of p53, phospho-p53 (ser15), and p21 proteins were significantly increased while phospho-p53 (Thr55) and survivin were significantly decreased after treatments of pre-DOX and LMB (P<0.05).

Doxorubicin 213-216 P53 Homo sapiens 62-65 22412944-9 2012 In conclusion, our results suggest that drug-resistant lung cancer cells with p53 wild type could be sensitized to cell death by scheduled combination treatment of DOX and LMB through activating and restoring p53 as well as potentially other signaling pathway(s) involving sequestosome 1. Doxorubicin 164-167 P53 Homo sapiens 78-81 22412944-9 2012 In conclusion, our results suggest that drug-resistant lung cancer cells with p53 wild type could be sensitized to cell death by scheduled combination treatment of DOX and LMB through activating and restoring p53 as well as potentially other signaling pathway(s) involving sequestosome 1. Doxorubicin 164-167 P53 Homo sapiens 209-212 22299029-1 2012 We have previously shown that TPA activates HTLV-1 LTR in Jurkat T-cells by inducing the binding of Sp1-p53 complex to the Sp1 site residing within the Ets responsive region 1 (ERR-1) of the LTR and that this activation is inhibited by PKCalpha and PKCepsilon. Tetradecanoylphorbol Acetate 30-33 P53 Homo sapiens 104-107 23139858-6 2012 This phenotypic change was completely reversed by p53 reactivation via treatment with proteasome inhibitor MG132 or co-knockdown of E3 ligase HDM2 and partially suppressed by ATP treatment. Adenosine Triphosphate 175-178 P53 Homo sapiens 50-53 22395499-10 2012 Frequency of Arg/Arg genotype of p53 gene was higher among cases (43%) compared with controls (33.3%), but the difference was not statistically significant (p=0.75). Arginine 13-16 P53 Homo sapiens 33-36 22395499-10 2012 Frequency of Arg/Arg genotype of p53 gene was higher among cases (43%) compared with controls (33.3%), but the difference was not statistically significant (p=0.75). Arginine 17-20 P53 Homo sapiens 33-36 22160723-7 2011 These cells exhibited a high yield of ROS-induced DNA single- and double-strand breaks and activation of the ATR-Chk1-ATM-Chk2-p53 pathway that led to Fas and caspase-8, -3, and -7 activation, whereas macrophages and DCs derived from them were protected.

Doxorubicin 123-134 P53 Homo sapiens 61-64 21869603-7 2011 In contrast, in the drug resistant cells which expressed activated Akt-1, much lower levels of p53 and p21 (Cip1) were induced upon exposure to doxorubicin. Doxorubicin 144-155 P53 Homo sapiens 95-98 21484135-9 2011 CONCLUSIONS: Although serum 249(serine) p53 mutation is rarely found in Taiwanese patients, HBV carriers have a higher prevalence of codon 72 mutants than patients with much severe liver diseases or HCV infection, which implies that codon 72 mutants may affect at an earlier stage of HBV infection.

Fluorouracil 10-14 P53 Homo sapiens 76-80 21674128-6 2011 TP53-depleted HCT116 cultures also had DSBs after high-dose 5-FU treatment but experienced a (transient) G1/S cell cycle arrest that protected them from apoptosis. Fluorouracil 60-64 P53 Homo sapiens 0-4 21674128-9 2011 DNA repair and cell cycle responses to 5-FU-induced DNA damage were distinctly affected by MMR and TP53 (role in BER/NER) functionalities, but MMR deficiency especially seemed to confer less overall sensitivity to 5-FU. Fluorouracil 39-43 P53 Homo sapiens 99-103 21821009-4 2011 With prolonged exposure to nocodazole, a microtubule-depolymerizing agent, p62-deficient HCT116 cells exhibited an accumulation of a polyploid population with a limited appearance of apoptotic cells, which was attributable to the attenuated stabilization of p53.

Epirubicin 114-124 P53 Homo sapiens 29-33 21514041-1 2011 PURPOSE: The aim of this study was to determine whether TP53 mutation status (MS) can predict response of breast cancer to paclitaxel followed by 5-FU/epirubicin/cyclophosphamide (P-FEC). Paclitaxel 123-133 P53 Homo sapiens 56-60 21660965-7 2011 Overexpression of CITED2 also decreased sensitivity to cisplatin in p53-defective H1299 cells when exogenous p53 expression was re-introduced. Cisplatin 55-64 P53 Homo sapiens 68-71 21660965-7 2011 Overexpression of CITED2 also decreased sensitivity to cisplatin in p53-defective H1299 cells when exogenous p53 expression was re-introduced. Cisplatin 55-64 P53 Homo sapiens 109-112 21660965-9 2011 Notably, the effects of CITED2 knockdown on p53 accumulation and the increase of p53"s target Bax were more pronounced after treatment with cisplatin. Cisplatin 140-149 P53 Homo sapiens 44-47 21660965-9 2011 Notably, the effects of CITED2 knockdown on p53 accumulation and the increase of p53"s target Bax were more pronounced after treatment with cisplatin. Cisplatin 140-149 P53 Homo sapiens 81-84 21660965-10 2011 Based on these results, we propose that a combination of cisplatin and CITED2 shRNA may represent an effective treatment against p53-sensitive cancer cells. Cisplatin 57-66 P53 Homo sapiens 129-132 21616106-1 2011 BACKGROUND & AIMS: Mutations in TP53, a tumor suppressor gene, are associated with prognosis of many cancers. Adenosine Monophosphate 12-15 P53 Homo sapiens 36-40 21316118-4 2011 The frequencies of p53 codon 72 polymorphisms (Arg/Arg, Arg/Pro, and Pro/Pro) in LC were 37.0%, 46.2%, and 16.7%, respectively; frequencies in the controls were 43.2%, 45.6%, and 11.2%, respectively (p<0.01). Arginine 47-50 P53 Homo sapiens 19-22 21316118-4 2011 The frequencies of p53 codon 72 polymorphisms (Arg/Arg, Arg/Pro, and Pro/Pro) in LC were 37.0%, 46.2%, and 16.7%, respectively; frequencies in the controls were 43.2%, 45.6%, and 11.2%, respectively (p<0.01). Arginine 51-54 P53 Homo sapiens 19-22 21316118-4 2011 The frequencies of p53 codon 72 polymorphisms (Arg/Arg, Arg/Pro, and Pro/Pro) in LC were 37.0%, 46.2%, and 16.7%, respectively; frequencies in the controls were 43.2%, 45.6%, and 11.2%, respectively (p<0.01). Arginine 51-54 P53 Homo sapiens 19-22 21441950-4 2011 We show here that the anthracyclines doxorubicin, daunorubicin and epirubicin further increase the amounts of mutant p53 mRNA and protein in cancer cells. Anthracyclines 22-36 P53 Homo sapiens 117-120 21705328-6 2011 Our data indicate that TPA-induced MnSOD expression was independent of p53 and most likely mediated by PKC-alpha-, and -epsilon-dependent signaling pathways. Tetradecanoylphorbol Acetate 23-26 P53 Homo sapiens 71-74 21441950-0 2011 Anthracyclines induce the accumulation of mutant p53 through E2F1-dependent and -independent mechanisms. Anthracyclines 0-14 P53 Homo sapiens 49-52 21441950-4 2011 We show here that the anthracyclines doxorubicin, daunorubicin and epirubicin further increase the amounts of mutant p53 mRNA and protein in cancer cells. Doxorubicin 37-48 P53 Homo sapiens 117-120 21441950-4 2011 We show here that the anthracyclines doxorubicin, daunorubicin and epirubicin further increase the amounts of mutant p53 mRNA and protein in cancer cells. Epirubicin 67-77 P53 Homo sapiens 117-120 21441950-8 2011 Instead, a natural antisense transcript of TP53, WRAP53, was strongly augmented by idarubicin and etoposide, but only less so by the other anthracyclines under study. Anthracyclines 139-153 P53 Homo sapiens 43-47 21441950-11 2011 Reducing the levels of mutant p53 by small-interfering RNA increased chemosensitivity, and idarubicin prevented cell survival more efficiently than the mutant p53-inducing doxorubicin. Doxorubicin 172-183 P53 Homo sapiens 159-162 21441950-12 2011 We conclude that even closely related anthracyclines induce the synthesis of different, opposing transcripts from the TP53 locus. Anthracyclines 38-52 P53 Homo sapiens 118-122 21712378-0 2011 Resveratrol induces p53-independent, X-linked inhibitor of apoptosis protein (XIAP)-mediated Bax protein oligomerization on mitochondria to initiate cytochrome c release and caspase activation.

Resveratrol 19-30 P53 Homo sapiens 39-42 21855805-2 2011 In particular, Set7/9 (KMT7)-mediated monomethylation of human p53 at lysine 372 (p53K372me1) was suggested to be essential for p53 activation in human cell lines.

Lysine 70-76 P53 Homo sapiens 82-85 21855806-3 2011 Originally defined as a critical layer of p53 regulation in human cell lines, p53 lysine methylation by Set7/9 (also called Setd7) was proposed to fulfill a similar function in vivo in the mouse, promoting p53 acetylation, stabilization, and activation upon DNA damage (Kurash et al., 2008). Lysine 82-88 P53 Homo sapiens 42-45 21855806-3 2011 Originally defined as a critical layer of p53 regulation in human cell lines, p53 lysine methylation by Set7/9 (also called Setd7) was proposed to fulfill a similar function in vivo in the mouse, promoting p53 acetylation, stabilization, and activation upon DNA damage (Kurash et al., 2008). Lysine 82-88 P53 Homo sapiens 78-81 21609781-10 2011 The noteworthy finding of this study is the activation of the sensor proteins, ATM and ATR by oxygen irradiation and the significant activation of Chk1, Chk2 and p53 only in the oxygen beam irradiated cells.

Arginine 106-114 P53 Homo sapiens 51-55 21832239-6 2011 This FACT inaccessibility leads to phosphorylation of the p53 Ser(392) by casein kinase 2 and inhibition of NF-kappaB-dependent transcription, which requires FACT activity at the elongation stage. Serine 62-65 P53 Homo sapiens 58-61 21548882-6 2011 Co-administration of 3BrPA (3-bromopyruvate), a well-known inhibitor of glycolysis, and succinate dehydrogenase, enhanced apoptosis and AMPK/p38(MAPK)/p53 signalling pathway activation. bromopyruvate 28-43 P53 Homo sapiens 151-154 21482024-7 2011 Ki23057 increased the p53 expression level in OCUM-2M/SN38 and OCUM-2M/PTX, but not in OCUM-2M/VP16. Paclitaxel 71-74 P53 Homo sapiens 22-25 21440619-6 2011 Furthermore, we found that interaction of PKCdelta and c-Abl played a crucial role in p53 accumulation in the nucleus, which was linked to the apoptosis of NPCs in response to high glucose. Glucose 181-188 P53 Homo sapiens 86-89 21655990-11 2011 Messenger RNA expression was significantly downregulated by metformin for PDE3B (phosphodiesterase 3B, cGMP-inhibited; a critical regulator of cAMP levels that affect activation of AMP-activated protein kinase, AMPK), confirmed by immunohistochemistry, SSR3, TP53 and CCDC14. Metformin 60-69 P53 Homo sapiens 259-263 21655990-11 2011 Messenger RNA expression was significantly downregulated by metformin for PDE3B (phosphodiesterase 3B, cGMP-inhibited; a critical regulator of cAMP levels that affect activation of AMP-activated protein kinase, AMPK), confirmed by immunohistochemistry, SSR3, TP53 and CCDC14. Cyclic AMP 143-147 P53 Homo sapiens 259-263 21655990-13 2011 Gene set analysis additionally revealed that p53, BRCA1 and cell cycle pathways also had reduced expression following metformin. Metformin 118-127 P53 Homo sapiens 45-48 21514377-5 2011 VRK1 (Vaccinia-related kinase 1) is an early response gene required for cyclin D1 expression, regulates p53 by a specific Thr18 phosphorylation, controls chromatin condensation by histone phosphorylation, nuclear envelope assembly by phosphorylation of BANF1, and participates in signalling required for Golgi fragmentation late in the G2 phase. UNII-PYZ33YLR8A 122-127 P53 Homo sapiens 104-107 21933600-5 2011 METHODS: The expression of P53 protein and MDM-2 protein was immunohistochemically detected using monoclonal antibodies in 242 paraffin embedded tissues, including 30 normal brain tissues from patients with craniocerebral injury and 212 tissues from patients with primary glioma (grade I - II group: 5 cases of grade I, 119 cases of grade II; and grade III--IV group: 53 cases of grade III, and 35 cases of grade IV). Paraffin 127-135 P53 Homo sapiens 27-30 21701263-1 2011 DNA damage, stalled replication forks, errors in mRNA splicing, and availability of nutrients activate specific phosphatidylinositiol-3 kinase-like kinases (PIKKs) that in turn phosphorylate downstream targets such as p53 on serine 15.

Cyclic AMP 51-55 P53 Homo sapiens 97-100 21750659-5 2011 In the present article, we provide a mechanistic insight into the regulation of p53 levels by cAMP. Cyclic AMP 94-98 P53 Homo sapiens 80-83 21750659-6 2011 We show that increased levels of cAMP augment the binding of p53 to its negative regulator HDM2, overriding the DNA damage-induced dissociation of p53 from HDM2. Cyclic AMP 33-37 P53 Homo sapiens 61-64 21750659-6 2011 We show that increased levels of cAMP augment the binding of p53 to its negative regulator HDM2, overriding the DNA damage-induced dissociation of p53 from HDM2. Cyclic AMP 33-37 P53 Homo sapiens 147-150 21750659-8 2011 The apoptosis inhibitory effect of cAMP is further shown to depend on this effect on p53 levels. Cyclic AMP 35-39 P53 Homo sapiens 85-88 21750659-9 2011 These findings potentially implicate deregulation of cAMP signaling as a candidate mechanism used by transformed cells to quench the p53 response while retaining wild-type p53. Cyclic AMP 53-57 P53 Homo sapiens 133-136 21750659-9 2011 These findings potentially implicate deregulation of cAMP signaling as a candidate mechanism used by transformed cells to quench the p53 response while retaining wild-type p53.

Doxorubicin 46-57 P53 Homo sapiens 124-127 21406194-4 2011 Here, we examined whether S-nitrosylation of the NF-kappaB, p53, and Wnt signaling proteins by NO-ASA might explain, in part, its mechanism of action in colon cancer. Aspirin 98-101 P53 Homo sapiens 60-63 21339736-14 2011 Although p53-pathway-dependent apoptotic agents could upregulate endogenous hOTAG-12b and p53 in UCI-101/107 OC cells, hOTAG-12b could also induce apoptosis in p53-null and platinum-resistant SKOV3 OC cells and Doxycycline-induced hOTAG-12b did not alter p53. hotag-12b 76-85 P53 Homo sapiens 9-12 21339736-15 2011 Further study showed that hOTAG-12b increases mRNAs of pro-apoptotic genes such as BAD, GADD45alpha and CIEDB, while inhibiting anti-apoptotic NAIP and Akt1 expression, suggesting that hOTAG-12b-induced apoptosis might be p53-independent. hotag-12b 26-35 P53 Homo sapiens 222-225 21353507-1 2011 The function of p53 induced by ganoderic acids (GAs) in anti-invasion was unknown, although our previous work reported the inhibition of tumor invasion and metastasis by Ganoderic acid T (GA-T). ganoderic acid S 31-46 P53 Homo sapiens 16-19 21406194-6 2011 Using a modified biotin switch assay we demonstrated that NO-ASA S-nitrosylates the signaling proteins p53, beta-catenin, and NF-kappaB, in colon cancer cells in a time- and concentration-dependent manner. Aspirin 61-64 P53 Homo sapiens 103-106 21480648-8 2011 In addition, the distinct p53 activation profile of 1 compared with cisplatin provides an explanation for the activity of this ruthenium drug against cisplatin-resistant cells. Cisplatin 150-159 P53 Homo sapiens 26-29 21737649-3 2011 We prepared H1299 cells (p53-null) with various mutations of p53 at three sites (serine 15, 20 and 46) and examined the radiosensitivity of the cells. Serine 81-87 P53 Homo sapiens 61-64 21539808-4 2011 We show that in the absence of PABP, the glycolytic enzyme GAPDH translocated to the cell nucleus and activated the GAPDH mediated apoptotic pathway by enhancing acetylation and serine 46 phosphorylation of p53.

Cisplatin 65-74 P53 Homo sapiens 56-59 21737649-4 2011 In three mutant forms of p53--S15A, S20A and S46A--serine was converted to alanine at these sites to prevent phosphorylation, and in two other mutant forms, S15D and S20D, serine was converted to aspartic acid to mimic phosphorylation. Serine 51-57 P53 Homo sapiens 25-28 21737649-4 2011 In three mutant forms of p53--S15A, S20A and S46A--serine was converted to alanine at these sites to prevent phosphorylation, and in two other mutant forms, S15D and S20D, serine was converted to aspartic acid to mimic phosphorylation.

Taxoids 40-47 P53 Homo sapiens 129-133 21518729-9 2011 In summary, our data show that ATM and p53 coordinately regulate FOXM1 via E2F to modulate epirubicin response and resistance in breast cancer.

Epirubicin 63-73 P53 Homo sapiens 8-11 21518729-3 2011 We also established that there is a loss of p53 function in MCF-7-EPI(R) cells and that epirubicin represses FOXM1 expression at transcription and gene promoter levels through activation of p53 and repression of E2F activity in MCF-7 cells. Epirubicin 88-98 P53 Homo sapiens 190-193 21479363-3 2011 Here, we used MCF-7 and MDA-MB231 breast cancer cells as a model to demonstrate that resveratrol induced the expression of ASPP1, a new member of the ASPP (apoptosis stimulation protein of p53) family, which plays an important role in the regulation of apoptosis. Resveratrol 85-96 P53 Homo sapiens 189-192 21518729-5 2011 Moreover, transient promoter transfection assays showed that epirubicin and its cellular effectors p53 and E2F1 modulate FOXM1 transcription through an E2F-binding site located within the proximal promoter region. Epirubicin 61-71 P53 Homo sapiens 99-102 21626334-6 2011 This mutation causes a nonsense mutation (Arg-to-Stop codon) that has been shown to attenuate p53 function.

Serine 86-89 P53 Homo sapiens 7-10 21576488-6 2011 If the damage cannot be fixed after a critical number of p53 pulses, then p53 is fully activated by further modifications such as phosphorylation at Ser-46 to trigger apoptosis, with its concentration switching to rather high levels. Serine 149-152 P53 Homo sapiens 74-77 21624110-6 2011 RESULTS: Clear synergism was observed when Doxorubicin and Nutlin-3a were combined in cell lines with wild-type TP53 and amplified MDM2, or with Methotrexate in both MDM2 normal and amplified sarcoma cell lines, allowing for up to tenfold reduction of cytotoxic drug dose.

Lysine 32-38 P53 Homo sapiens 25-28 21087144-5 2011 The current study demonstrates that DC cells signal a DNA damage response through p53 and its downstream mediator, p21(WAF/CIP), which is accompanied by an elevation in steady-state levels of superoxide and percent glutathione disulfide, both indicators of oxidative stress. Superoxides 192-202 P53 Homo sapiens 82-85 21087144-7 2011 Further, restoring telomerase activity or inhibiting p53 or p21(WAF/CIP) significantly mitigated growth inhibition as well as caused a significant decrease in steady-state levels of superoxide. Superoxides 182-192 P53 Homo sapiens 53-56 21087144-8 2011 Our results support a model in which telomerase insufficiency in DC leads to p21(WAF/CIP) signaling, via p53, to cause increased steady-state levels of superoxide, metabolic oxidative stress, and senescence. Superoxides 152-162 P53 Homo sapiens 105-108 21248071-1 2011 HIPK2 activates the apoptotic arm of the DNA damage response by phosphorylating tumor suppressor p53 at serine 46.

Doxorubicin 0-11 P53 Homo sapiens 75-78 21156795-6 2011 Surprisingly, in p53-negative cells, doxorubicin-mediated cell death was more aggressive (faster and intense). Doxorubicin 37-48 P53 Homo sapiens 17-20 21156795-7 2011 Doxorubicin increased the amount of Fas ligand (FasL) by enhancing activator protein (AP) 1 DNA binding in both p53-positive and p53-negative cells, but the basal expression of Fas was higher in p53-negative cells. Doxorubicin 0-11 P53 Homo sapiens 112-115 21156795-7 2011 Doxorubicin increased the amount of Fas ligand (FasL) by enhancing activator protein (AP) 1 DNA binding in both p53-positive and p53-negative cells, but the basal expression of Fas was higher in p53-negative cells. Doxorubicin 0-11 P53 Homo sapiens 129-132 21156795-7 2011 Doxorubicin increased the amount of Fas ligand (FasL) by enhancing activator protein (AP) 1 DNA binding in both p53-positive and p53-negative cells, but the basal expression of Fas was higher in p53-negative cells. Doxorubicin 0-11 P53 Homo sapiens 129-132 21156795-9 2011 Activation of caspases was faster in p53-negative cells upon doxorubicin treatment.

Doxorubicin 72-83 P53 Homo sapiens 50-53 21366897-5 2011 RESULTS: We found that sensitivity to cisplatin correlates significantly with levels of EGR-1 expression in tumors with wild-type p53/INK4a/p16 status. Cisplatin 38-47 P53 Homo sapiens 130-133 21107702-7 2011 However, Complex I and II activities in the mitochondria were compromised only in wt p53-bearing cells after doxorubicin treatment, but not in mutant p53-bearing cells. Doxorubicin 109-120 P53 Homo sapiens 85-88 21107702-8 2011 Similarly, doxorubicin treatment caused greater cell death only in wt p53-bearing cells, but not in mutant p53-bearing cells.

Gefitinib 18-27 P53 Homo sapiens 76-79 21216229-12 2011 Our findings also suggest that p53 not only stimulates apoptosis-related event but also inhibits the drug-resistance ability of Aurora-A, and consequently promotes the gefitinib-induced cellular apoptotic process. Gefitinib 168-177 P53 Homo sapiens 31-34 21148320-7 2011 Specifically, acetylation of p53 at lysine 120, a DNA-binding domain residue mutated in human cancer, is essential for triggering apoptosis.

Curcumin 0-10 P53 Homo sapiens 123-126 21167259-9 2011 Taken together, these findings indicate that curcumin I protects dopaminergic neurons from 6-OHDA-induced toxicity via the reduction of ROS production, and subsequent attenuation of p53 phosphorylation and reduction of the Bax/Bcl-2 ratio. Curcumin 45-55 P53 Homo sapiens 182-185 21378327-5 2011 The effect of zeranol-serum on mRNA expression of cell cycle regulating gene (cyclin D1) and tumor suppressor genes (p53, and p21) was evaluated using real-time RT-PCR.

Nitric Oxide 40-52 P53 Homo sapiens 271-274 21118815-10 2011 However, other DNA damage response markers such as up-regulation and serine 15 phosphorylation of p53 or serine 1524 phosphorylation of BRCA1 were not triggered by LACV infection.

Fluorouracil 66-70 P53 Homo sapiens 207-210 20425122-4 2011 RESULTS: In the urothelial bladder cancer cell lines RT4 and T24, 5-FU-induced TS inhibition proved to be associated with cell type-dependent (a) sensitivity to the drug, (b) Caspase-mediated apoptosis, (c) p53 stabilization and activation, as well as Rb phosphorylation and E2F1 expression and (d) transcriptional regulation of p53 target genes and their cognate proteins, while an E2F-dependent transcriptional network did not seem to be critically engaged in such type of responses. Fluorouracil 66-70 P53 Homo sapiens 329-332 20425122-5 2011 CONCLUSIONS: We have shown that in the wild-type p53 context of RT4 cells, 5-FU-triggered apoptosis was prominently efficient and mainly regulated by p53-dependent mechanisms, whereas the mutant p53 environment of T24 cells was able to provide notable levels of resistance to apoptosis, basically ascribed to E2F-independent, and still unidentified, pathways. Fluorouracil 75-79 P53 Homo sapiens 49-52 20425122-5 2011 CONCLUSIONS: We have shown that in the wild-type p53 context of RT4 cells, 5-FU-triggered apoptosis was prominently efficient and mainly regulated by p53-dependent mechanisms, whereas the mutant p53 environment of T24 cells was able to provide notable levels of resistance to apoptosis, basically ascribed to E2F-independent, and still unidentified, pathways.

Morphine 0-8 P53 Homo sapiens 36-39 21194611-1 2011 The p53 tumor suppressor protein is one of the key checkpoints in cellular response to a variety of stress mechanisms, including exposure to various toxic metal complexes. Metals 155-160 P53 Homo sapiens 4-7 21194611-4 2011 Previous studies have shown that uranyl acetate and uranyl nitrate are capable of inducing DNA strand breaks and potentially of inducing oxidative stress through free radical generation, two potential mechanisms for activation of p53. Uranyl Nitrate 52-66 P53 Homo sapiens 230-233 21194611-5 2011 Based on these studies, we hypothesized that either uranyl acetate or uranyl nitrate could act as an activator of p53. Uranyl Nitrate 70-84 P53 Homo sapiens 114-117 21194611-7 2011 All of our results demonstrate that there is not a p53-mediated response to either uranyl acetate or uranyl nitrate, demonstrating that any cellular response to uranium exposure likely occurs in a p53-independent fashion under the conditions studied. Uranium 161-168 P53 Homo sapiens 197-200 21051157-9 2011 Therefore we hypothesized that due to reduction in the testosterone levels, elevation in the DHT levels, and over-expression of p53 gene, morphine could prevent neural stem cell proliferation.

Arginine 199-202 P53 Homo sapiens 175-178 20346999-7 2010 Additionally, bolus (3h) doxorubicin incubation led to phosphorylation of p53 at serine 392, induction of p21, G2 arrest and increase of proapoptotic protein Bax. Tritium 21-23 P53 Homo sapiens 74-77 20512840-3 2010 Actually, polymorphic variants Arg and Pro were found to have different properties of regulation of TP53-dependent DNA repair target genes, that can effect various levels of chromosome aberrations in cancer patients with these genotypes. Arginine 31-34 P53 Homo sapiens 100-104 20512840-5 2010 It was shown that the Arg variant of TP53 gene is associated with high frequency of AC and chromatid breaks. Arginine 22-25 P53 Homo sapiens 37-41 20428827-7 2010 The study demonstrated that cisplatin induces K562 cells to apoptosis by reducing miR-106 which up-regulates RB1 or by inhibiting miR-150 which increases P53 expression. Cisplatin 28-37 P53 Homo sapiens 154-157 20299546-0 2010 2,3,7,8-tetrachlorodibenzo-p-dioxin counteracts the p53 response to a genotoxicant by upregulating expression of the metastasis marker agr2 in the hepatocarcinoma cell line HepG2. Polychlorinated Dibenzodioxins 0-35 P53 Homo sapiens 52-55 20299546-2 2010 In this study, we show that TCDD treatment counteracts the p53 activation (phosphorylation and acetylation) elicited by a genotoxic compound, etoposide, in the human hepatocarcinoma cell line HepG2 and we delineated the mechanisms of this interaction. Polychlorinated Dibenzodioxins 28-32 P53 Homo sapiens 59-62 20299546-9 2010 These results suggest that AhR ligands such as TCDD might contribute to tumor progression by inhibiting p53 regulation (phosphorylation and acetylation) triggered by genotoxicants via the increased expression of the metastasis marker AGR2. Polychlorinated Dibenzodioxins 47-51 P53 Homo sapiens 104-107 20504344-8 2010 Importantly, inhibition of miR-21 and miR-222 by anti-miRNA oligonucleotides induced a significant increase in caspase activity in fludarabine-treated p53-mutant MEG-01 cells, suggesting that miR-21 and miR-222 up-regulation may be involved in the establishment of fludarabine resistance. Oligonucleotides 60-76 P53 Homo sapiens 151-154 20504360-0 2010 Resveratrol suppresses IGF-1 induced human colon cancer cell proliferation and elevates apoptosis via suppression of IGF-1R/Wnt and activation of p53 signaling pathways. Resveratrol 0-11 P53 Homo sapiens 146-149 20504360-8 2010 Resveratrol treatment induced apoptosis by activating tumor suppressor p53 protein, whereas IGF-1R siRNA treatment did not affect apoptosis. Resveratrol 0-11 P53 Homo sapiens 71-74 20504360-9 2010 Our data suggests that resveratrol not only suppresses cell proliferation by inhibiting IGF-1R and its downstream signaling pathways similar to that of IGF-1R siRNA but also enhances apoptosis via activation of the p53 pathway. Resveratrol 23-34 P53 Homo sapiens 215-218 20428768-7 2010 The phosphorylations of both p38 MAP kinase and p53 induced by doxorubicin were suppressed by low doses of ionizing radiation. Doxorubicin 63-74 P53 Homo sapiens 48-51 20428768-10 2010 The results thus suggest that low doses of radiation suppress doxorubicin-induced replicative senescence through the inhibition of p38-dependent phosphorylation of p53 and by activation of ERK1/2, without genomic damage. Doxorubicin 62-73 P53 Homo sapiens 164-167 20483782-6 2010 We also demonstrate that IFN-gamma treatment, which is used to induce IgG2a switching, increases intracellular ROS levels, and activates p53 in switching B cells, and show that p53 inhibits IgG2a class switching through its antioxidant-regulating function. Reactive Oxygen Species 111-114 P53 Homo sapiens 177-180 20351180-3 2010 p400, an SWI2/SNF2-related ATPase that serves as an ATP-dependent chromatin remodeling enzyme, exists as an integral subunit of a TIP60 complex but also resides within a distinct complex that presumably lacks TIP60 and appears to be involved in the transcriptional repression of basal p53 target gene expression. Adenosine Triphosphate 27-30 P53 Homo sapiens 285-288 20368352-7 2010 Mechanistically, ATDC binds p53, and this interaction is potentially fine-tuned by posttranslational acetylation of lysine 116 on ATDC. Lysine 116-122 P53 Homo sapiens 28-31 20428827-3 2010 We also showed that miR-106 and miR-150 were down-regulated while their target genes (RB1 and P53, respectively) were up-regulated after cisplatin treatment. Cisplatin 137-146 P53 Homo sapiens 94-97 20058240-1 2010 BACKGROUND: We previously described the identification of a transcriptional inhibitor ARC and FoxM1 inhibitors, thiazole antibiotics, Siomycin A and thiostrepton that were able to induce potent p53-independent apoptosis in cancer cell lines of different origin. siomycin A 134-144 P53 Homo sapiens 194-197 20058240-1 2010 BACKGROUND: We previously described the identification of a transcriptional inhibitor ARC and FoxM1 inhibitors, thiazole antibiotics, Siomycin A and thiostrepton that were able to induce potent p53-independent apoptosis in cancer cell lines of different origin. Thiostrepton 149-161 P53 Homo sapiens 194-197 20353948-0 2010 RUNX3 modulates DNA damage-mediated phosphorylation of tumor suppressor p53 at Ser-15 and acts as a co-activator for p53. Serine 79-82 P53 Homo sapiens 72-75 20353948-2 2010 In this study, we found that RUNX3 is closely involved in DNA damage-dependent phosphorylation of tumor suppressor p53 at Ser-15 and acts as a co-activator for p53. Serine 122-125 P53 Homo sapiens 115-118 20353948-2 2010 In this study, we found that RUNX3 is closely involved in DNA damage-dependent phosphorylation of tumor suppressor p53 at Ser-15 and acts as a co-activator for p53. Serine 122-125 P53 Homo sapiens 160-163 20353948-3 2010 The small interference RNA-mediated knockdown of RUNX3 inhibited adriamycin (ADR)-dependent apoptosis in p53-proficient cells but not in p53-deficient cells in association with a significant reduction of p53-target gene expression as well as phosphorylation of p53 at Ser-15. Doxorubicin 65-75 P53 Homo sapiens 105-108 20353948-8 2010 Additionally, RUNX3 had an ability to induce the phosphorylation of p53 at Ser-15, thereby promoting p53-dependent apoptosis. Serine 75-78 P53 Homo sapiens 68-71 20353948-8 2010 Additionally, RUNX3 had an ability to induce the phosphorylation of p53 at Ser-15, thereby promoting p53-dependent apoptosis. Serine 75-78 P53 Homo sapiens 101-104 20353948-11 2010 Thus, our present results strongly suggest that RUNX3 acts as a novel co-activator for p53 through regulating its DNA damage-induced phosphorylation at Ser-15 and also provide a clue to understanding the molecular mechanisms underlying RUNX3-mediated tumor suppression. Serine 152-155 P53 Homo sapiens 87-90 20504360-10 2010 CONCLUSIONS: For the first time, we report that resveratrol suppresses colon cancer cell proliferation and elevates apoptosis even in the presence of IGF-1 via suppression of IGF-1R/Akt/Wnt signaling pathways and activation of p53, suggesting its potential role as a chemotherapeutic agent. Resveratrol 48-59 P53 Homo sapiens 227-230 20346999-7 2010 Additionally, bolus (3h) doxorubicin incubation led to phosphorylation of p53 at serine 392, induction of p21, G2 arrest and increase of proapoptotic protein Bax. Doxorubicin 25-36 P53 Homo sapiens 74-77 20346999-7 2010 Additionally, bolus (3h) doxorubicin incubation led to phosphorylation of p53 at serine 392, induction of p21, G2 arrest and increase of proapoptotic protein Bax. Serine 81-87 P53 Homo sapiens 74-77 20346999-9 2010 Continuous (24h) treatment with 5 microM doxorubicin resulted in cell cycle arrest in G0/G1 phase that was neither accompanied by phosphorylation and activation of p53 nor enhanced expression of p21. Doxorubicin 41-52 P53 Homo sapiens 164-167 20225330-8 2010 Furthermore, stratification analyses showed that the risk of SPM associated with p53 variant genotypes (Arg/Pro + Pro/Pro) was more pronounced in several subgroups.

Lysine 299-305 P53 Homo sapiens 260-263 20470425-3 2010 Cisplatin resistance is multi-factorial but can be associated with increased DNA repair capacity, mutations in p53 or loss of DNA mismatch repair capacity. Cisplatin 0-9 P53 Homo sapiens 111-114 20470425-7 2010 Decreased TC-NER capacity was associated with an increase in the sensitivity of tumour cells to cisplatin-induced apoptosis, even in p53 null and DNA mismatch repair-deficient cell lines. Cisplatin 96-105 P53 Homo sapiens 133-136 20406839-7 2010 RESULTS: TRAIL/doxorubicin combination induced marked STS local and metastatic growth inhibition in a p53-independent manner. Doxorubicin 15-26 P53 Homo sapiens 102-105 20356045-9 2010 Taken together, these data suggested that in addition to the mitochondrial- and Fas receptor-mediated apoptotic pathways involved, ROS-dependent and p53-regulated DR5 expression was also demonstrated to play a pivotal role in the synergistic enhancement of TRAIL-induced apoptosis instigated by 6-DG in Hep G2 cells. Reactive Oxygen Species 131-134 P53 Homo sapiens 149-152 20646592-5 2010 And the expressions of cell cycle protein P53, P21, CDK2 were detected by Western blot after the treatment of capsaicin. Capsaicin 110-119 P53 Homo sapiens 42-45 20646592-11 2010 After a 48-hour treatment with capsaicin, the expressions of P53 and P21 were up-regulated in contrary to the expression of CDK2. Capsaicin 31-40 P53 Homo sapiens 61-64 20646592-12 2010 CONCLUSION: Capsaicin induces the cell cycle arrest of bladder cancer RT4 cells G(0)/G(1) phase and growth inhibition via TRPV1 receptor by modulating the expression of P53, P21 and CDK2. Capsaicin 12-21 P53 Homo sapiens 169-172 20459745-0 2010 NSC109268 potentiates cisplatin-induced cell death in a p53-independent manner. Cisplatin 22-31 P53 Homo sapiens 56-59 20459745-7 2010 The objective of the present study is to determine if p53 is responsible for cisplatin sensitization by NSC109268. Cisplatin 77-86 P53 Homo sapiens 54-57 20459745-10 2010 Cisplatin caused a concentration-dependent increase in p53 in 2008 and 2008/C13* cells, and the induction of p53 correlated with cisplatin-induced apoptosis as determined by the cleavage of PARP. Cisplatin 0-9 P53 Homo sapiens 55-58 20459745-10 2010 Cisplatin caused a concentration-dependent increase in p53 in 2008 and 2008/C13* cells, and the induction of p53 correlated with cisplatin-induced apoptosis as determined by the cleavage of PARP. Cisplatin 0-9 P53 Homo sapiens 109-112 20459745-10 2010 Cisplatin caused a concentration-dependent increase in p53 in 2008 and 2008/C13* cells, and the induction of p53 correlated with cisplatin-induced apoptosis as determined by the cleavage of PARP. Cisplatin 129-138 P53 Homo sapiens 109-112 20459745-11 2010 NSC109268 alone had no effect on p53 but it enhanced p53 level in response to cisplatin. Cisplatin 78-87 P53 Homo sapiens 53-56 20459757-5 2010 Oxygen tension also affects many mammalian transactivators including AP-1, NFkB, and p53 by affecting the reduced state of critical cysteines in these proteins. Oxygen 0-6 P53 Homo sapiens 85-88 20459757-5 2010 Oxygen tension also affects many mammalian transactivators including AP-1, NFkB, and p53 by affecting the reduced state of critical cysteines in these proteins. Cysteine 132-141 P53 Homo sapiens 85-88 20190805-6 2010 Delta133p53 expression is increased in response to DNA damage by doxorubicin in p53 wild-type cell lines, but not in p53-mutated cells.

Doxorubicin 65-76 P53 Homo sapiens 80-83 20219657-6 2010 This HY253-induced G(1) phase arrest is associated with decreased expression of cyclin D and up-regulation of p21(CIP1), via p53 phosphorylation at Ser-15, which resulted in increased hypophosphorylated pRb in A549 cells. Serine 148-151 P53 Homo sapiens 125-128 20658010-1 2010 UNLABELLED: p53 tumoral suppressor gene harbors a functional polymorphism which codes either arginine (Arg) or proline (Pro) in the protein p53 of codon 72.

Fatty Acids 177-187 P53 Homo sapiens 111-114 20421506-3 2010 We found that the transactivation domain of p53 made specific interactions with the C-terminal oligonucleotide/oligosaccharide-binding-fold domains of BRCA2 (BRCA2(CTD)). Oligonucleotides 95-110 P53 Homo sapiens 44-47 20459648-3 2010 The expressions of IDH1 and p53 in formalin-fixed paraffin-embedded tissue sections from 44 osteosarcoma patients were determined by immunohistochemistry, and the correlation between them and clinicopagthological features were analyzed.

Arginine 35-43 P53 Homo sapiens 31-34 20407015-7 2010 At high levels of galactose-induced p53 expression, 12 of 21 mutants that retain transactivation seemed similar to wild-type. Galactose 18-27 P53 Homo sapiens 36-39 20395957-6 2010 Our findings demonstrate that (i) PKR, Ser/Thr kinase, phosphorylates its new substrate Cdc2 at the Tyr 4 residue, (ii) PKR-mediated Tyr 4-phosphorylation facilitates Cdc2 ubiquitination and proteosomal degradation, (iii) unphosphorylated Tyr 4 prevents Cdc2 ubiquitination, and (iv) downstream from p53, PKR has a crucial role in G2 arrest and triggers Cdc2 downregulation under genotoxic conditions. Tyrosine 100-103 P53 Homo sapiens 300-303 20395957-6 2010 Our findings demonstrate that (i) PKR, Ser/Thr kinase, phosphorylates its new substrate Cdc2 at the Tyr 4 residue, (ii) PKR-mediated Tyr 4-phosphorylation facilitates Cdc2 ubiquitination and proteosomal degradation, (iii) unphosphorylated Tyr 4 prevents Cdc2 ubiquitination, and (iv) downstream from p53, PKR has a crucial role in G2 arrest and triggers Cdc2 downregulation under genotoxic conditions.

Tyrosine 133-136 P53 Homo sapiens 300-303 20406950-3 2010 It is known that the interaction of the vitamin D metabolite 1,25-dihydroxyvitamin D(3) (1,25D) with its functional vitamin D receptor leads to differentiation, G(1) arrest, and increased cell survival in p53-null AML cells. Vitamin D 40-49 P53 Homo sapiens 205-208 20406950-6 2010 We find that 1,25D alone induces monocytic differentiation in these cell lines similar to that seen in p53-null AML cells, suggesting that the presence of wild-type p53 is compatible with activation of vitamin D signaling. Vitamin D 202-211 P53 Homo sapiens 165-168 20372852-12 2010 Our findings indicate the possible association of the Glu allele of the TP53BP1 Asp353Glu polymorphism with lower risk of lung cancer especially among the Pro allele carriers of the TP53 Arg72Pro polymorphism. Glutamic Acid 54-57 P53 Homo sapiens 72-76 20338640-4 2010 Analysis of the expression pattern of a key set of cell cycle regulators revealed that the expression of Zta and Rta substantially interfered with the cell cycle regulatory machinery in Raji cells, strongly inhibiting the expression of Rb and p53 and inducing the expression of E2F1. zta 105-108 P53 Homo sapiens 243-246 20372863-7 2010 Cisplatin treatment induced caspase-3, -9, p53, Bax, NF-kappaB and MAPK expression, and suppressed Bcl-2 and Bcl-xl expression, whereas cells transfected with pcDNA3.1-ARL6IP1 showed lower levels of cisplatin-induced caspase-3, -9, p53, Bax, NF-kappaB and MAPK up-regulation and higher levels of cisplatin-suppressed Bcl-2 and Bcl-xl down-regulation. Cisplatin 0-9 P53 Homo sapiens 43-46 20372863-7 2010 Cisplatin treatment induced caspase-3, -9, p53, Bax, NF-kappaB and MAPK expression, and suppressed Bcl-2 and Bcl-xl expression, whereas cells transfected with pcDNA3.1-ARL6IP1 showed lower levels of cisplatin-induced caspase-3, -9, p53, Bax, NF-kappaB and MAPK up-regulation and higher levels of cisplatin-suppressed Bcl-2 and Bcl-xl down-regulation. Cisplatin 0-9 P53 Homo sapiens 232-235 20228054-3 2010 Here, we show that p53-dependent apoptosis in response to different DNA-damaging agents was reduced when normal and cancer cells were cultured at physiological oxygen tensions instead of the usual atmospheric levels. Oxygen 160-166 P53 Homo sapiens 19-22 20372863-8 2010 These novel findings collectively suggest that ARL6IP1 may play a key role in cisplatin-induced apoptosis in CaSki cervical cancer cells by regulating the expression of apoptosis-associated proteins such as caspase-3, -9, p53, NF-kappaB, MAPK, Bcl-2, Bcl-xl, and Bax. Cisplatin 78-87 P53 Homo sapiens 222-225 20422012-4 2010 Surprisingly, unlike the case for other p53 target promoters, p53-mediated transactivation of FLT1-T constructs or expression of the endogenous FLT1 gene, as well as binding of p53 and ER at the promoter constructs, was inducible by doxorubicin but not by 5-fluorouracil. Doxorubicin 233-244 P53 Homo sapiens 62-65 20167603-5 2010 DYRK1A and DYRK3 directly phosphorylate SIRT1 at Thr(522), promoting deacetylation of p53. Threonine 49-52 P53 Homo sapiens 86-89 20208557-0 2010 15-Deoxy-Delta(12,14)-prostaglandin J(2) stabilizes, but functionally inactivates p53 by binding to the cysteine 277 residue. Cysteine 104-112 P53 Homo sapiens 82-85 20208557-6 2010 Moreover, by conducting an in vitro [(35)S]-labeled p53 translation assay, we identified cysteine 277 as a putative site of p53 modification by 15d-PGJ(2).

Cysteine 89-97 P53 Homo sapiens 124-127 20208557-10 2010 In conclusion, 15d-PGJ(2) can undergo nucleophilic addition to p53, presumably at the cysteine 277 residue, rendering this tumor suppressor less susceptible to proteasomal degradation. Cysteine 86-94 P53 Homo sapiens 63-66 20140020-6 2010 Furthermore, treatment with the non-genotoxic agent Nutlin-3 sensitizes cells for doxorubicin, showing that activation of p53 by targeting its regulators is an efficient strategy to decrease cell viability of breast cancer cells. Doxorubicin 82-93 P53 Homo sapiens 122-125 20422012-4 2010 Surprisingly, unlike the case for other p53 target promoters, p53-mediated transactivation of FLT1-T constructs or expression of the endogenous FLT1 gene, as well as binding of p53 and ER at the promoter constructs, was inducible by doxorubicin but not by 5-fluorouracil. Doxorubicin 233-244 P53 Homo sapiens 62-65 20351271-0 2010 Phosphate-activated glutaminase (GLS2), a p53-inducible regulator of glutamine metabolism and reactive oxygen species. Reactive Oxygen Species 94-117 P53 Homo sapiens 42-45 20422012-4 2010 Surprisingly, unlike the case for other p53 target promoters, p53-mediated transactivation of FLT1-T constructs or expression of the endogenous FLT1 gene, as well as binding of p53 and ER at the promoter constructs, was inducible by doxorubicin but not by 5-fluorouracil.

Phosphates 33-42 P53 Homo sapiens 16-19 20351271-1 2010 We identified a p53 target gene, phosphate-activated mitochondrial glutaminase (GLS2), a key enzyme in conversion of glutamine to glutamate, and thereby a regulator of glutathione (GSH) synthesis and energy production. Glutamic Acid 130-139 P53 Homo sapiens 16-19 20422012-4 2010 Surprisingly, unlike the case for other p53 target promoters, p53-mediated transactivation of FLT1-T constructs or expression of the endogenous FLT1 gene, as well as binding of p53 and ER at the promoter constructs, was inducible by doxorubicin but not by 5-fluorouracil.

Glutathione 168-179 P53 Homo sapiens 16-19 20227390-0 2010 Rosiglitazone enhances the radiosensitivity of p53-mutant HT-29 human colorectal cancer cells. Rosiglitazone 0-13 P53 Homo sapiens 47-50 20351271-1 2010 We identified a p53 target gene, phosphate-activated mitochondrial glutaminase (GLS2), a key enzyme in conversion of glutamine to glutamate, and thereby a regulator of glutathione (GSH) synthesis and energy production. Glutathione 181-184 P53 Homo sapiens 16-19 20351271-4 2010 Further, siRNA down-regulation of either GLS2 or p53 compromises the GSH-dependent antioxidant system and increases intracellular ROS levels. Glutathione 69-72 P53 Homo sapiens 49-52 20351271-4 2010 Further, siRNA down-regulation of either GLS2 or p53 compromises the GSH-dependent antioxidant system and increases intracellular ROS levels. Reactive Oxygen Species 130-133 P53 Homo sapiens 49-52 20351271-5 2010 High ROS levels following GLS2 knockdown also coincide with stimulation of p53-induced cell death. Reactive Oxygen Species 5-8 P53 Homo sapiens 75-78 20351271-6 2010 We propose that GLS2 control of intracellular ROS levels and the apoptotic response facilitates the ability of p53 to protect cells from accumulation of genomic damage and allows cells to survive after mild and repairable genotoxic stress. Reactive Oxygen Species 46-49 P53 Homo sapiens 111-114 20351271-9 2010 Thus, our results provide evidence for a unique metabolic role for p53, linking glutamine metabolism, energy, and ROS homeostasis, which may contribute to p53 tumor suppressor function. Reactive Oxygen Species 114-117 P53 Homo sapiens 67-70 20351271-9 2010 Thus, our results provide evidence for a unique metabolic role for p53, linking glutamine metabolism, energy, and ROS homeostasis, which may contribute to p53 tumor suppressor function. Reactive Oxygen Species 114-117 P53 Homo sapiens 155-158 19922265-4 2010 Expression of the p53-regulated downstream proteins like p21, and DNA-damage-dependent p53 phosphorylation at serine-15 residue also was not elicited by the CUVA treatment, at a low coralyne concentration. Serine 110-116 P53 Homo sapiens 18-21 19922265-4 2010 Expression of the p53-regulated downstream proteins like p21, and DNA-damage-dependent p53 phosphorylation at serine-15 residue also was not elicited by the CUVA treatment, at a low coralyne concentration. Serine 110-116 P53 Homo sapiens 87-90 20418953-1 2010 BACKGROUND: Homeodomain interacting protein kinase 2 (HIPK2) is an evolutionary conserved serine/threonine kinase whose activity is fundamental in maintaining wild-type p53 function, thereby controlling the destiny of cells when exposed to DNA damaging agents. Serine 90-96 P53 Homo sapiens 169-172 20138829-5 2010 In this study we found that curcumin induces apoptotic cell death in MCF-7 cells, as assessed by MTT assay, DNA ladder formation, PARP cleavage, p53 and Bax induction. Curcumin 28-36 P53 Homo sapiens 145-148 20140014-7 2010 The regulation of the p53 family by S100 is complicated and depends on the target preference of each individual S100 protein, the concentration of the proteins and calcium, as well as the splicing variation of p63 or p73. Calcium 164-171 P53 Homo sapiens 22-25 20378837-7 2010 Consistent with these functions of GLS2, the activation of p53 increases the levels of glutamate and alpha-ketoglutarate, mitochondrial respiration rate, and GSH levels and decreases reactive oxygen species (ROS) levels in cells. Glutamic Acid 87-96 P53 Homo sapiens 59-62 20378837-7 2010 Consistent with these functions of GLS2, the activation of p53 increases the levels of glutamate and alpha-ketoglutarate, mitochondrial respiration rate, and GSH levels and decreases reactive oxygen species (ROS) levels in cells. Glutathione 158-161 P53 Homo sapiens 59-62 20378837-7 2010 Consistent with these functions of GLS2, the activation of p53 increases the levels of glutamate and alpha-ketoglutarate, mitochondrial respiration rate, and GSH levels and decreases reactive oxygen species (ROS) levels in cells. Reactive Oxygen Species 183-206 P53 Homo sapiens 59-62 20378837-7 2010 Consistent with these functions of GLS2, the activation of p53 increases the levels of glutamate and alpha-ketoglutarate, mitochondrial respiration rate, and GSH levels and decreases reactive oxygen species (ROS) levels in cells. Reactive Oxygen Species 208-211 P53 Homo sapiens 59-62 20398418-6 2010 An increased risk was also associated with the TP53 Pro/Pro genotype (OR = 2.22, 95% CI = 1.58-3.10) compared to the Arg/Arg genotype. Arginine 117-120 P53 Homo sapiens 47-51 20398418-6 2010 An increased risk was also associated with the TP53 Pro/Pro genotype (OR = 2.22, 95% CI = 1.58-3.10) compared to the Arg/Arg genotype. Arginine 121-124 P53 Homo sapiens 47-51 20354524-7 2010 RESULTS: Oncogenic KRAS sensitised colorectal tumour cells to oxaliplatin and 5-FU in a p53-dependent manner and promoted p53 phosphorylation at Ser37 and Ser392, without affecting p53 stabilisation, p21 induction, or cell-cycle arrest. Fluorouracil 78-82 P53 Homo sapiens 88-91 20354524-11 2010 CONCLUSION: Oncogenic KRAS determines the cellular response to p53 activation by oxaliplatin or 5-FU, by facilitating apoptosis induction through Noxa. Fluorouracil 96-100 P53 Homo sapiens 63-66 20227390-3 2010 In this study, rosiglitazone treatment significantly reduced the cell viability of p53-wild type HCT116 cells but not p53-mutant HT-29 cells. Rosiglitazone 15-28 P53 Homo sapiens 83-86 20227390-4 2010 Interestingly, rosiglitazone pretreatment enhanced radiosensitivity in p53-mutant HT-29 cells but not HCT116 cells, and prolonged radiation-induced G(2)/M arrest and enhanced radiation-induced cell growth inhibition in HT-29 cells. Rosiglitazone 15-28 P53 Homo sapiens 71-74 19882681-7 2010 In contrast, in breast cancer cells transfected with MT1 exposed to 1.2 microT of the 50 Hz EMF, the expression of p53 and c-myc increased significantly after melatonin treatment but for p21(WAF) the increase was not significant.

Oligonucleotides 68-83 P53 Homo sapiens 117-120 19882681-6 2010 Expression of BRCA-1, p53, p21(WAF), and c-myc was increased by estradiol stimulation and subsequently decreased by melatonin treatment in both cell lines, except for p53 expression in the transfected cell line, thereby proving the antiestrogenic effect of melatonin at molecular level. Estradiol 64-73 P53 Homo sapiens 22-25 19882681-6 2010 Expression of BRCA-1, p53, p21(WAF), and c-myc was increased by estradiol stimulation and subsequently decreased by melatonin treatment in both cell lines, except for p53 expression in the transfected cell line, thereby proving the antiestrogenic effect of melatonin at molecular level.

Fluorouracil 115-119 P53 Homo sapiens 24-27 19810096-8 2010 The combination of the p53 codon 72 polymorphism and p53 mutation status is a potential predictive marker of sensitivity to 5-FU in CRC.

Fluorouracil 124-128 P53 Homo sapiens 53-56 19810096-4 2010 5-FU sensitivity of tumor cells without inactive p53 mutation in the arginine/arginine (Arg/Arg) variant was significantly higher than that of tumor cells with or without inactive p53 mutation in other variants (p = 0.022), whereas the 5-FU sensitivity of tumor cells with inactive p53 mutation in the Arg/Arg variant was significantly lower than that of tumor cells with or without inactive p53 mutation in other variants (p = 0.002).

Serine 52-55 P53 Homo sapiens 29-32 20123963-3 2010 To elucidate the direct phosphorylation of p53 at Ser46 by ATM, an ATM mutant (ATM-AS) sensitive to ATP analogues was engineered. Adenosine Triphosphate 100-103 P53 Homo sapiens 43-46 20123963-4 2010 In vitro kinase assays revealed that p53 was phosphorylated at Ser46 by ATM-AS, even when ATP analogues were used as phosphate donors, although this phosphorylation site is not in an SQ motif, a consensus ATM site. Adenosine Triphosphate 90-93 P53 Homo sapiens 37-40 20123963-4 2010 In vitro kinase assays revealed that p53 was phosphorylated at Ser46 by ATM-AS, even when ATP analogues were used as phosphate donors, although this phosphorylation site is not in an SQ motif, a consensus ATM site. Phosphates 117-126 P53 Homo sapiens 37-40 20123963-7 2010 These results suggest that ATM phosphorylates a noncanonical serine residue on p53 by mechanisms different from those for the phosphorylation of Ser15. Serine 61-67 P53 Homo sapiens 79-82 20034524-11 2010 These results suggest that p53 plays a pivotal role in decreased integrin-mediated extracellular matrix component expression in cisplatin-induced tubule cell apoptosis, and reveal a novel aspect of PACAP-mediated renoprotection.

Arginine 56-64 P53 Homo sapiens 39-43 19521721-5 2009 Similarly, the alleles of rs1042522 in TP53 that encode arginine (G-allele) or proline (C-allele) at codon 72, which cause increased pro-apoptotic (G-allele) or cell-cycle arrest activities (C-allele), respectively, may moderate p53"s ability to prevent DNA damage. Arginine 56-64 P53 Homo sapiens 229-232 19452524-8 2009 This was especially true for TP53 transversion mutations and dietary antioxidants (OR for beta-carotene 0.51 95% CI 0.27, 0.97, p trend 0.03; alpha-tocopherol 0.41 95% CI 0.20, 0.84, p trend 0.02) Beta-carotene and ibuprofen significantly altered risk of KRAS2 tumors. Ibuprofen 215-224 P53 Homo sapiens 29-33 19834285-2 2009 We found that silibinin exhibited a protective effect against chemotherapeutic reagent mitomycin C-induced cell death in A375-S2 cells in a p53-dependent manner, which contradicted the findings of previous studies investigating the anti-neoplastic activity of silibinin and developing silibinin as a potential anti-neoplastic drug in clinical therapy. Silybin 14-23 P53 Homo sapiens 140-143 20157557-4 2009 Addition of nutlin restored doxorubicin-induced p53 protein and transcriptional activity in senescent cells to the levels in early passage cells but only partially restored its apoptotic activity, suggesting that changes in both upstream and downstream p53 signaling during senescence are responsible for attenuated response to genotoxic stress. Doxorubicin 28-39 P53 Homo sapiens 48-51 19596268-5 2009 In fact, most of the lymphoma cell lines expressing high levels of galectin-7 did not express any detectable level of p53, although expressed p21(Waf1/Cip1) gene following doxorubicin treatment, indicating that p53 was functional in these cells.

Fluorouracil 77-81 P53 Homo sapiens 106-109 19605487-6 2009 We examined here whether an association between core and HAX-1 has any functional relevance to p53 modulation in 5-FU-treated cells. Fluorouracil 113-117 P53 Homo sapiens 95-98 19605487-9 2009 Further, 5-FU-mediated p53 expression was reduced with concurrent HAX-1 suppression in core- or polyprotein-expressing cells compared to control HepG2 cells, and caspase-2 and -7 activities were diminished. Fluorouracil 9-13 P53 Homo sapiens 23-26 19605487-11 2009 These observations underscore an association between HCV core and HAX-1, which promotes 5-FU mediated p53-dependent caspase-7 activation and hepatocyte growth inhibition. Fluorouracil 88-92 P53 Homo sapiens 102-105 19681600-0 2009 Effect of thioredoxin deletion and p53 cysteine replacement on human p53 activity in wild-type and thioredoxin reductase null yeast.

Cysteine 33-42 P53 Homo sapiens 75-78 19681600-8 2009 Unexpectedly, substitution at cysteine C275 also inactivated p53, which was the first evidence for a non-zinc-coordinating cysteine being essential for p53 function. Cysteine 30-38 P53 Homo sapiens 61-64 19681600-8 2009 Unexpectedly, substitution at cysteine C275 also inactivated p53, which was the first evidence for a non-zinc-coordinating cysteine being essential for p53 function.

Cysteine 123-131 P53 Homo sapiens 61-64 19681600-8 2009 Unexpectedly, substitution at cysteine C275 also inactivated p53, which was the first evidence for a non-zinc-coordinating cysteine being essential for p53 function. Cysteine 123-131 P53 Homo sapiens 152-155 19681600-9 2009 Cysteine substitutions at six positions (C124, C135, C141, C182, C229, and C277) neither inactivated p53 nor relieved the requirement for thioredoxin reductase. Cysteine 0-8 P53 Homo sapiens 101-104 19681600-11 2009 The results suggested that p53 dependence on thioredoxin reductase either was indirect, perhaps mediated by an upstream activator of p53, or was due to oxidation of one or more of the four essential cysteines. Cysteine 199-208 P53 Homo sapiens 27-30 19705844-6 2009 The specific ATM inhibitor caffeine significantly decreased tricetin-mediated G2/M arrest by inhibiting the phosphorylation of p53 (serine 15) and Chk2.

Doxorubicin 28-39 P53 Homo sapiens 253-256 19805293-6 2009 The N-terminal 616 aa of CBP, which includes the conserved Zn(2+)-binding C/H1-TAZ1 domain, was the minimal domain sufficient to destabilize p53 in vivo, and it included within an intrinsic E3 autoubiquitination activity and, in a two-step E4 assay, exhibited robust E4 activity for p53. Zinc 59-65 P53 Homo sapiens 141-144 19784392-8 2009 CONCLUSIONS: Our preliminary results indicate that the arginine variant of rs1042522 within p53 is associated with increased risk of POAG. Arginine 55-63 P53 Homo sapiens 92-95 19738071-10 2009 Taken together, our results provide new insights on the mechanism of action of pomalidomide and lenalidomide in the regulation of gene transcription, imply possible efficacy in p53 mutated and deleted cancer, and suggest new potential clinical uses as an epigenetic therapy. pomalidomide 79-91 P53 Homo sapiens 177-180 19706948-6 2009 Comparing the cell cycle change, Glu-GNPs induced acceleration in the G0/G1 phase and accumulation of cells in the G2/M phase at 29.8% versus 18.4% for controls at 24 h. G2/M arrest was accompanied by decreased expression of p53 and cyclin A, and increased expression of cyclin B1 and cyclin E. In conclusion, Glu-GNPs trigger activation of the CDK kinases leading to cell cycle acceleration in the G0/G1 phase and accumulation in the G2/M phase. Glutamic Acid 33-36 P53 Homo sapiens 225-228 19581934-2 2009 Drug-resistant KB cells selected with cisplatin or oxaliplatin were found to have increased p53 levels and in oxaliplatin-selected cells, a larger p53 predominantly in the cytoplasm.

Cisplatin 84-93 P53 Homo sapiens 102-105 19796081-0 2009 Oligonucleotide probe array for p53 gene alteration analysis in DNA from formalin-fixed paraffin-embedded breast cancer tissues. Paraffin 88-96 P53 Homo sapiens 32-35 19796081-2 2009 We sequenced the p53 gene in DNA extracted from archival paraffin-embedded BC tissues and compared the results obtained from direct sequencing with those obtained by oligonucleotide probe array (OPA). Paraffin 57-65 P53 Homo sapiens 17-20 19578044-7 2009 Furthermore, p53 promotes cisplatin-induced apoptosis by directly binding and counteracting Bcl-x(L) antiapoptotic function. Cisplatin 26-35 P53 Homo sapiens 13-16 19184017-0 2009 Doxorubicin-induced mitochondrial dysfunction is secondary to nuclear p53 activation in H9c2 cardiomyoblasts. Doxorubicin 0-11 P53 Homo sapiens 70-73 19184017-4 2009 RESULTS: Doxorubicin accumulation in the nucleus was detected after 3 h treatment, followed by an increase in p53 and a decrease in mitochondrial membrane potential. Doxorubicin 9-20 P53 Homo sapiens 110-113 19184017-7 2009 Importantly, pifithrin-alpha, a p53 inhibitor, protected against DOX-induced mitochondrial depolarization, caspase activation and cell death. Doxorubicin 65-68 P53 Homo sapiens 32-35 19184017-8 2009 CONCLUSION: Mitochondrial dysfunction in H9c2 myoblasts treated with DOX is a consequence of nuclear p53 activation rather than a direct effect of the drug on mitochondria. Doxorubicin 69-72 P53 Homo sapiens 101-104 19578044-8 2009 In conclusion, our findings suggest a novel mode of action for cisplatin to overcome Bcl-2-mediated protection against apoptosis, which requires preferential activation of Bak and p53-mediated upregulation of Noxa protein levels and lipid peroxidation. Cisplatin 63-72 P53 Homo sapiens 180-183 19652535-0 2009 Wild-type p53 protects normal cells against apoptosis induced by thiostrepton. Thiostrepton 65-77 P53 Homo sapiens 10-13 19890497-1 2009 Pin1 specifically catalyzes the cis/trans isomerization of phospho-Ser/Thr-Pro bonds and plays an important role in many cellular events through the effects of conformational change on the function of its biological substrates, including cell division cycle 25 C (Cdc25C), c-Jun and p53. Serine 67-70 P53 Homo sapiens 283-286 19652535-4 2009 We found that only normal cells that have wild-type p53 were resistant to the thiazole antibiotic, thiostrepton, suggesting that p53 plays an antiapoptotic role in normal cells. Thiostrepton 99-111 P53 Homo sapiens 52-55 19652535-4 2009 We found that only normal cells that have wild-type p53 were resistant to the thiazole antibiotic, thiostrepton, suggesting that p53 plays an antiapoptotic role in normal cells. Thiostrepton 99-111 P53 Homo sapiens 129-132 19652535-5 2009 In this case p53 status, but not the transformation of cells per se determines their sensitivity to thiostrepton and possibly to other anticancer drugs. Thiostrepton 100-112 P53 Homo sapiens 13-16 19652535-6 2009 Since p53 is mutated in 50% of human cancers, thiostrepton may selectively kill cancer, but not normal cells.

Hydrogen Peroxide 49-57 P53 Homo sapiens 66-69 19633417-8 2009 Interestingly, several of these compounds share the ability to target thiols and affect the redox state of p53, indicating that this is critical for mutant p53 rescue.

Serine 130-133 P53 Homo sapiens 140-143 19397953-5 2009 Furthermore, the results indicate that DNA damage, quantified by apurinic-apyrimidinic site counting assay and phosphorylation of Ser-15 in P53 protein, is induced in CD3+ T cells by morphine in a naloxone-sensitive manner. Morphine 183-191 P53 Homo sapiens 140-143 19397953-6 2009 GENERAL SIGNIFICANCE: Because it was shown that only the kappa opioid receptor gene is expressed in CD3+ T cells in the opioid receptor family, the present study suggests that morphine induces DNA damage through the action on the kappa opioid receptor, which leads to immune suppression by activation of P53-mediated signal transduction.

Cisplatin 104-113 P53 Homo sapiens 61-64 19578756-6 2009 The differential resistance of RT4 and T24 cells to cisplatin-induced apoptosis was associated with an RT4-specific phosphorylation (Ser15; Ser392) pattern of p53, together with structural amputations of the Akt and XIAP anti-apoptotic regulators.

Lysine 70-76 P53 Homo sapiens 44-47 19494119-4 2009 Although initial studies showed that Lys-120 acetylation plays a role in p53 function in the nucleus, we report here a role for Lys-120 acetylation in transcription-independent apoptosis. Lysine 37-40 P53 Homo sapiens 73-76 19494119-5 2009 We demonstrate that the Lys-120-acetylated isoform of p53 is enriched at mitochondria. Lysine 24-27 P53 Homo sapiens 54-57 19494119-9 2009 These data support a model whereby Lys-120 acetylation contributes to both the transcription-dependent and -independent apoptotic pathways induced by p53. Lysine 35-38 P53 Homo sapiens 150-153 19603033-2 2009 In addition, the mismatch repair protein, hMLH1, has been linked to DNA damage-induced apoptosis by cisplatin by both p53-dependent and -independent mechanisms.

Cisplatin 35-39 P53 Homo sapiens 124-127 18391982-4 2008 As the mechanism, triptolide suppressed CDDP-induced p53 transcriptional activity, leading to p21 attenuation, which promoted apoptosis via the activation of c-Jun N-terminal kinase (JNK) and Bax.

Cysteine 110-113 P53 Homo sapiens 175-178 18502749-4 2008 This association also depended on Cys(242) (and, to some extent, on Cys(238)) within the central DNA binding domain of p53. Cysteine 34-37 P53 Homo sapiens 119-122 18502749-4 2008 This association also depended on Cys(242) (and, to some extent, on Cys(238)) within the central DNA binding domain of p53.

Hydrogen Peroxide 174-191 P53 Homo sapiens 102-105 18490454-6 2008 Moreover, Cdk5 (cyclin-dependent kinase 5), a proline-directed Ser/Thr kinase, additionally increases p53 stability via post-translational modification of p53 in response to hydrogen peroxide. Hydrogen Peroxide 174-191 P53 Homo sapiens 155-158 18490454-9 2008 Our results show that c-Abl and Cdk5 cooperatively regulate maximal activation of p53, resulting in neuronal death in response to oxidative stress by hydrogen peroxide.

Anthracyclines 151-165 P53 Homo sapiens 79-82 18325917-2 2008 We analysed the efficacy of a preoperative combination between 5-fluorouracil, anthracyclines and cyclophosphamide according to both p53 status and molecular classification. Fluorouracil 63-77 P53 Homo sapiens 133-136 18325917-9 2008 CONCLUSION: p53 status may have a different predictive value for efficacy of anthracycline/alkylating agents-based regimen in each molecular subclass, a result which may explain the different results reported in literature. Anthracyclines 77-90 P53 Homo sapiens 12-15 18421307-11 2008 In summary, HIF-1 targeted therapy to reverse hypoxia-related cisplatin resistance depends on normal p53 status.

Zinc Sulfate 27-39 P53 Homo sapiens 103-106 18507431-3 2008 We show that resveratrol induces apoptosis in Jeko-1 cells and modulates several key molecules, including cyclin D1 (CCND1), p53 (TP53), p21 (CDKN1A), BCL2, BAX, Bcl XL (BCL2L1), caspase 9 (CASP9) and p27 (CDKN1B). Resveratrol 13-24 P53 Homo sapiens 125-128 18549324-5 2008 RESULTS/CONCLUSION: The p53 gene is mutated in half of all human tumors and such cancers would be predicted to produce lower levels of CDAFs. cdafs 135-140 P53 Homo sapiens 24-27 18549324-6 2008 We therefore believe that p53 function can be partially compensated by therapeutic use of CDAFs, which offers a promising new avenue for cancer treatment. cdafs 90-95 P53 Homo sapiens 26-29 18593873-2 2008 A recent study in Genes & Development by Xue and colleagues (1439-1444) now provides in vivo evidence that DLC1, a negative regulator of Rho, is a tumor suppressor gene deleted almost as frequently as p53 in common cancers such as breast, colon, and lung. Adenosine Monophosphate 25-28 P53 Homo sapiens 205-208 18661375-5 2008 RESULTS: In radio-resistant subclones generated from wt p53-transfected SAOS-2 cells DNA deletions were remarkably reduced and the accumulation of "common" deletion at mtDNA (that may let the persistence of oxidative damage by precluding detoxification from reactive oxygen species [ROS]) completely abrogated.

Arginine 60-63 P53 Homo sapiens 37-40 18249029-13 2008 This study suggests that individuals with keratosis are more susceptible to arsenic-induced health effects and genetic damage and that the arginine variant of p53 can further influence the repair capacity of arsenic-exposed individuals, leading to increased accumulation of chromosomal aberrations.

Reactive Oxygen Species 124-147 P53 Homo sapiens 157-160 18468580-3 2008 Cisplatin (cDDP) yields intra- and inter-strand DNA cross-links and several proteins that recognise cDDP-induced DNA damage, such as p53, are also targets of poly(ADP-ribosyl)ation. Cisplatin 0-9 P53 Homo sapiens 133-136 18468580-3 2008 Cisplatin (cDDP) yields intra- and inter-strand DNA cross-links and several proteins that recognise cDDP-induced DNA damage, such as p53, are also targets of poly(ADP-ribosyl)ation. Cisplatin 11-15 P53 Homo sapiens 133-136 18468580-3 2008 Cisplatin (cDDP) yields intra- and inter-strand DNA cross-links and several proteins that recognise cDDP-induced DNA damage, such as p53, are also targets of poly(ADP-ribosyl)ation. Cisplatin 100-104 P53 Homo sapiens 133-136 18468580-4 2008 We compared the effects of treatments with cDDP and the PARPs inhibitor PJ34 in p53 mutated carcinoma cell lines (HeLa, KB, HT29) that exhibited differential sensitivities to the drugs, in terms of cell growth inhibition and onset of apoptosis. Cisplatin 43-47 P53 Homo sapiens 80-83 18559494-0 2008 Cisplatin induces p53-dependent FLICE-like inhibitory protein ubiquitination in ovarian cancer cells. Cisplatin 0-9 P53 Homo sapiens 18-21 18559494-2 2008 Although p53 and FLICE-like inhibitory protein (FLIP) are determinants of CDDP sensitivity in ovarian cancer, the interaction between p53 and FLIP remains poorly understood. Cisplatin 74-78 P53 Homo sapiens 9-12 18559494-3 2008 Here, using two chemosensitive ovarian cancer cell lines and various molecular and cellular approaches, we show that CDDP induces p53-dependent FLIP ubiquitination and degradation, and apoptosis in vitro. Cisplatin 117-121 P53 Homo sapiens 130-133 18559494-4 2008 Moreover, we showed that Itch (an E3 ligase) forms a complex with FLIP and p53 upon CDDP treatment. Cisplatin 84-88 P53 Homo sapiens 75-78 18559494-5 2008 These results suggest that p53 facilitates FLIP down-regulation by CDDP-induced FLIP ubiquitination and proteasomal degradation. Cisplatin 67-71 P53 Homo sapiens 27-30 18523266-10 2008 Intracellular reactive oxygen species (ROS) generation after MG132 treatment contributed to p53, but not p65 nuclear translocation and DNA-binding activity. Reactive Oxygen Species 14-37 P53 Homo sapiens 92-95 18523266-10 2008 Intracellular reactive oxygen species (ROS) generation after MG132 treatment contributed to p53, but not p65 nuclear translocation and DNA-binding activity. Reactive Oxygen Species 39-42 P53 Homo sapiens 92-95 18523266-13 2008 These findings reveal that proteasome inhibitor-mediated NF-kappaB and ROS-dependent p53 activation are contributed to intronic regulation of DR5 transcription, and resulted in the subsequent enhancement of TRAIL-induced apoptosis in human lung cancer cells. Reactive Oxygen Species 71-74 P53 Homo sapiens 85-88 18523266-7 2008 The protein stability, Ser(392) phosphorylation and Lys(373)/Lys(382) acetylation of p53 were enhanced by MG132. Lysine 52-55 P53 Homo sapiens 85-88 18523266-7 2008 The protein stability, Ser(392) phosphorylation and Lys(373)/Lys(382) acetylation of p53 were enhanced by MG132.

Cisplatin 7-16 P53 Homo sapiens 75-78 18402767-3 2008 During adriamycin (ADR)-mediated apoptosis, UNC5H4 was significantly induced in p53-proficient U2OS cells but not in p53-deficient H1299 cells. Doxorubicin 7-17 P53 Homo sapiens 80-83 18223681-3 2008 During cisplatin (CDDP)-mediated apoptosis in neuroblastoma SH-SY5Y cells, p53 was induced to accumulate in association with an increase in expression levels of NEDL1. Cisplatin 18-22 P53 Homo sapiens 75-78 18367875-4 2008 In the present study, we treated HT-29 (mutant p53) and LoVo (wild type p53) human colorectal cancer cells with different concentrations of GTP, which led to repression of cell proliferation and induction of apoptosis in both cell lines.

Water 22-27 P53 Homo sapiens 137-140 18397889-3 2008 Here, we use RNA interference to reduce p53 expression in CHRF cells and show that reduced p53 activity leads to a greater fraction of polyploid cells, higher mean and maximum ploidy, accelerated DNA synthesis, and delayed apoptosis and cell death upon phorbol 12-myristate 13-acetate-induced Mk differentiation. Tetradecanoylphorbol Acetate 253-284 P53 Homo sapiens 91-94 18400748-4 2008 We found that after prolonged nocodazole exposure, the postmitotic checkpoint was facilitated by p53. Nocodazole 30-40 P53 Homo sapiens 97-100 18506185-0 2008 Cisplatin alters nitric oxide synthase levels in human ovarian cancer cells: involvement in p53 regulation and cisplatin resistance.

Cisplatin 136-145 P53 Homo sapiens 185-188 18506185-5 2008 The NO donor S-nitroso-N-acetylpenicillamine (SNAP) increased p53 protein levels and induced apoptosis in both cell types, and enhanced cisplatin-induced apoptosis in C13(*) cells in a p53-dependent manner (i.e., enhancement blocked by p53 siRNA). Cisplatin 136-145 P53 Homo sapiens 185-188 18454317-7 2008 In melanoma cells, resveratrol inhibits STAT3 and NF-kappaB-dependent transcription, culminating in suppression of cFLIP and Bcl-xL expression, while activating the MAPK- and the ATM-Chk2-p53 pathways. Resveratrol 19-30 P53 Homo sapiens 188-191 18367875-4 2008 In the present study, we treated HT-29 (mutant p53) and LoVo (wild type p53) human colorectal cancer cells with different concentrations of GTP, which led to repression of cell proliferation and induction of apoptosis in both cell lines. Guanosine Triphosphate 140-143 P53 Homo sapiens 72-75 18367875-5 2008 Meanwhile, we also observed increased PUMA expression and decreased ERK (extracellular signal-regulated kinase) activity in both of GTP-treated tumor cell lines carrying different genotypes of p53. Guanosine Triphosphate 132-135 P53 Homo sapiens 193-196 18367875-10 2008 Demonstration of the molecular mechanism involved in the anti-cancer effect of GTP may be useful in the therapeutic target selection for p53 deficient colorectal cancer. Guanosine Triphosphate 79-82 P53 Homo sapiens 137-140 18954551-5 2008 Only three from the eight TP53 polymorphisms described in the analyzed region were polymorphic within our samples: the 11827 base from intron 2, the 16bp duplication in the intron3 and the codon 72 (Arg>Pro) from exon 4. Arginine 199-202 P53 Homo sapiens 26-30 18495657-4 2008 Mesalazine inhibited the growth of HCT-116 and HT-29 cells, two CRC cell lines that express either a wild-type or mutated p53.

Serine 69-72 P53 Homo sapiens 62-65 18519674-11 2008 Inhibition of PP-2A activity enhances p53 phosphorylation at Ser-15 and up-regulates Bak expression to promote EGCG-induced apoptosis. Serine 61-64 P53 Homo sapiens 38-41 18519674-13 2008 In summary, our results show that (a) PP-2A directly dephosphorylates p53 at Ser-15; (b) P53 directly controls Bak expression; and (c) EGCG negatively regulates PP-2A. Serine 77-80 P53 Homo sapiens 70-73 18497992-1 2008 To understand one of the mechanisms of resistance to chemoradiation in colon cancer cells, we investigated whether 5-fluorouracil (5-FU) mediated the expression of epidermal growth factor receptor (EGFR) and modified repair of radiation-induced DNA damage, especially in a p53 independent pathway. Fluorouracil 131-135 P53 Homo sapiens 273-276 18331776-6 2008 It was found that the treatment of OE33 cells with flavones and flavonols caused G2/M arrest through up-regulation of GADD45beta and 14-3-3sigma and down-regulation of cyclin B1 at the mRNA and protein levels, and induced p53-independent mitochondrial-mediated apoptosis through up-regulation of PIG3 and cleavage of caspase-9 and caspase-3. Flavones 51-59 P53 Homo sapiens 222-225 18331776-6 2008 It was found that the treatment of OE33 cells with flavones and flavonols caused G2/M arrest through up-regulation of GADD45beta and 14-3-3sigma and down-regulation of cyclin B1 at the mRNA and protein levels, and induced p53-independent mitochondrial-mediated apoptosis through up-regulation of PIG3 and cleavage of caspase-9 and caspase-3. Flavonols 64-73 P53 Homo sapiens 222-225 18272544-9 2008 Phosphorylation of p53 at site Ser15 and Chk1 at Ser317, as well as accumulation of p21(waf1/cip1), was observed within 8-24 h. Superoxide dismutase and catalase were unable to overcome this G2/M arrest, possibly indicating that neutrophil products other than superoxide or H(2)O(2) are involved in this cellular response. Superoxides 260-270 P53 Homo sapiens 19-22 18395248-2 2008 HIPK2 regulates p53-apoptotic function via serine-46 (Ser46) phosphorylation and activation of p53 is a key determinant in ovarian cancer cell death. Serine 43-49 P53 Homo sapiens 16-19 18395248-9 2008 Thus, 2008C13 cells were resistant to cisplatin but sensitive to adriamycin-induced apoptosis through activation of the HIPK2/p53Ser46 pathway. Doxorubicin 65-75 P53 Homo sapiens 126-129 18410999-0 2008 Hdm2 and nitric oxide radicals contribute to the p53-dependent radioadaptive response. Nitric Oxide 9-21 P53 Homo sapiens 49-52 18497992-9 2008 Interaction of EGFR and ERCC1 might correlate with radiation-induced DNA damage when p53 mutant colon cancer cell lines are exposed to 5-FU followed by radiation.

Ethanol 4-11 P53 Homo sapiens 62-65 18566213-5 2008 Indeed, we found that CDDP treatment induced the up-regulation of p53 in both sensitive and resistant A2780 cell lines. Cisplatin 22-26 P53 Homo sapiens 66-69 18443131-0 2008 Phosphorylation of Thr18 and Ser20 of p53 in Ad-p53-induced apoptosis. UNII-PYZ33YLR8A 19-24 P53 Homo sapiens 48-51 18443131-5 2008 Here we use Ad-p53 constructs to test the hypothesis that simultaneous phosphorylation of p53 at threonine 18 (Thr18) and serine 20 (Ser20) is causally associated with p53-mediated apoptosis. Threonine 97-106 P53 Homo sapiens 90-93 18454141-3 2008 Enhanced autophagy improved the survival of p53-deficient cancer cells under conditions of hypoxia and nutrient depletion, allowing them to maintain high ATP levels. Adenosine Triphosphate 154-157 P53 Homo sapiens 44-47 18443131-5 2008 Here we use Ad-p53 constructs to test the hypothesis that simultaneous phosphorylation of p53 at threonine 18 (Thr18) and serine 20 (Ser20) is causally associated with p53-mediated apoptosis. Threonine 97-106 P53 Homo sapiens 90-93 18443131-5 2008 Here we use Ad-p53 constructs to test the hypothesis that simultaneous phosphorylation of p53 at threonine 18 (Thr18) and serine 20 (Ser20) is causally associated with p53-mediated apoptosis. UNII-PYZ33YLR8A 111-116 P53 Homo sapiens 90-93 18443131-5 2008 Here we use Ad-p53 constructs to test the hypothesis that simultaneous phosphorylation of p53 at threonine 18 (Thr18) and serine 20 (Ser20) is causally associated with p53-mediated apoptosis. UNII-PYZ33YLR8A 111-116 P53 Homo sapiens 90-93 18443131-6 2008 Studies using phosphorylation-specific antibodies demonstrated that p53-induced apoptosis correlates with phosphorylation of p53 at Thr18 and Ser20 but not with carboxy-terminal phosphorylation (Ser392). UNII-PYZ33YLR8A 132-137 P53 Homo sapiens 68-71 18443131-6 2008 Studies using phosphorylation-specific antibodies demonstrated that p53-induced apoptosis correlates with phosphorylation of p53 at Thr18 and Ser20 but not with carboxy-terminal phosphorylation (Ser392). UNII-PYZ33YLR8A 132-137 P53 Homo sapiens 125-128 18516295-2 2008 We have previously shown that mutational inactivation of p53 results in sensitization to paclitaxel. Paclitaxel 89-99 P53 Homo sapiens 57-60 18443131-11 2008 We thus conclude that phosphorylation of Thr18 and Ser20 is sufficient for inducing p53-mediated apoptosis in glioma cells. UNII-PYZ33YLR8A 41-46 P53 Homo sapiens 84-87 18516295-7 2008 Sensitization to paclitaxel-induced apoptosis was also achieved by p53-siRNA transfection in wild type p53 H460 cells. Paclitaxel 17-27 P53 Homo sapiens 67-70 18472002-0 2008 Arginine methylation of hnRNP K enhances p53 transcriptional activity. Arginine 0-8 P53 Homo sapiens 41-44 18516295-7 2008 Sensitization to paclitaxel-induced apoptosis was also achieved by p53-siRNA transfection in wild type p53 H460 cells.

Serine 51-57 P53 Homo sapiens 77-80 18440733-7 2008 Phosphorylation of p53 protein at serines 15, 20, 46 and 392 increased in MCF-7 cells. Serine 34-41 P53 Homo sapiens 19-22 18440733-10 2008 These results suggest that serine 392 phosphorylation is the first stabilizing event of p53 associated with BP exposure and subsequent cell death in MCF-7 cells. Serine 27-33 P53 Homo sapiens 88-91 18600534-0 2008 Functional inactivity and mutations of p53 differentially affect sensitivity to 5-fluorouracil and antifolate inhibitors of thymidylate synthase (TS) by altering TS levels in colorectal cancer cells. Fluorouracil 80-94 P53 Homo sapiens 39-42 18472002-1 2008 Previous studies have illustrated that hnRNP K, which could be methylated at arginine residues, plays a key role in coordinating transcriptional responses to DNA damage as a cofactor for p53. Arginine 77-85 P53 Homo sapiens 187-190 18472002-3 2008 Furthermore, arginine methylation of hnRNP K enhanced its affinity with p53. Arginine 13-21 P53 Homo sapiens 72-75 18472002-5 2008 These data suggested that arginine methylation of hnRNP K is a key element for p53 transcriptional activity. Arginine 26-34 P53 Homo sapiens 79-82 18406507-7 2008 Activation of p53 was evidenced by its phosphorylation at serine 15 (Ser15) and acetylation at lysine 382 (Lys382). Serine 58-64 P53 Homo sapiens 14-17 18406507-7 2008 Activation of p53 was evidenced by its phosphorylation at serine 15 (Ser15) and acetylation at lysine 382 (Lys382). Lysine 95-101 P53 Homo sapiens 14-17 18406507-10 2008 SB203580 and PD98059, specific inhibitors of p38 MAPK and ERK, respectively, suppressed phosphorylation of p53 at Ser15, but the accumulation of p53 was only moderately reduced. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 13-20 P53 Homo sapiens 107-110 18406507-10 2008 SB203580 and PD98059, specific inhibitors of p38 MAPK and ERK, respectively, suppressed phosphorylation of p53 at Ser15, but the accumulation of p53 was only moderately reduced. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 13-20 P53 Homo sapiens 145-148 18261847-0 2008 Cooperation between p53 and p73 in cisplatin-induced apoptosis in ovarian carcinoma cells. Cisplatin 35-44 P53 Homo sapiens 20-23 18406507-11 2008 Acetylation of p53 at Lys 382 was not affected by these inhibitors, suggesting that acetylation stabilizes p53 in response to DNA damage. Lysine 22-25 P53 Homo sapiens 15-18 18342637-1 2008 Apigenin, a plant flavone, potentially activates wild-type p53 and induces apoptosis in cancer cells. flavone 18-25 P53 Homo sapiens 59-62 18342637-3 2008 Exposure of human prostate cancer 22Rv1 cells, harboring wild-type p53, to growth-suppressive concentrations (10-80 microM) of apigenin resulted in the stabilization of p53 by phosphorylation on critical serine sites, p14ARF-mediated downregulation of MDM2 protein, inhibition of NF-kappaB/p65 transcriptional activity, and induction of p21/WAF-1 in a dose- and time-dependent manner. Serine 204-210 P53 Homo sapiens 169-172 18342637-7 2008 Apigenin-mediated p53 activation and apoptosis were further attenuated by p53 antisense oligonucleotide treatment. Oligonucleotides 88-103 P53 Homo sapiens 18-21 18342637-7 2008 Apigenin-mediated p53 activation and apoptosis were further attenuated by p53 antisense oligonucleotide treatment. Oligonucleotides 88-103 P53 Homo sapiens 74-77 18261847-5 2008 Although p73 appears to be implicated mainly in response to high stress conditions, the available results support a cooperation between p53 and p73 in cisplatin-induced apoptosis in sensitive cells. Cisplatin 151-160 P53 Homo sapiens 136-139 18269916-0 2008 Induction of p21 by p65 in p53 null cells treated with Doxorubicin.

Doxorubicin 95-98 P53 Homo sapiens 110-113 18269916-5 2008 In HCT116 (p53-/-) cells, downregulation of p65 expression enhanced the cytotoxic effect of DOX, due to decreased p21 expression levels. Doxorubicin 92-95 P53 Homo sapiens 11-14 18269916-6 2008 We present evidence that in p53-null tumor cells treated with DOX, p65 was involved in induction of p21 expression by directly binding to the p21 promoter. Doxorubicin 62-65 P53 Homo sapiens 28-31 18294283-2 2008 We have previously found that doxorubicin increased the p53 levels in cells containing p53-binding HBx protein and restored the p53-mediated transcriptional activity that was suppressed by HBx.

Doxorubicin 30-41 P53 Homo sapiens 87-90 18376141-1 2008 We showed that tumor cells with wild-type p53 and high levels of Bcl-x(L) are cisplatin resistant but are induced to undergo apoptosis by (-)-gossypol, making this a promising agent for overcoming cisplatin resistance. Cisplatin 78-87 P53 Homo sapiens 42-45 18294283-2 2008 We have previously found that doxorubicin increased the p53 levels in cells containing p53-binding HBx protein and restored the p53-mediated transcriptional activity that was suppressed by HBx. Doxorubicin 30-41 P53 Homo sapiens 87-90 18376141-1 2008 We showed that tumor cells with wild-type p53 and high levels of Bcl-x(L) are cisplatin resistant but are induced to undergo apoptosis by (-)-gossypol, making this a promising agent for overcoming cisplatin resistance. Gossypol 138-150 P53 Homo sapiens 42-45 18376141-1 2008 We showed that tumor cells with wild-type p53 and high levels of Bcl-x(L) are cisplatin resistant but are induced to undergo apoptosis by (-)-gossypol, making this a promising agent for overcoming cisplatin resistance. Cisplatin 197-206 P53 Homo sapiens 42-45 18294283-4 2008 We found that six phosphorylation sites of the Serine residues of p53 were efficiently phosphorylated in HBx-expressing ChangX-34 cells, suggesting that the binding of HBx to the p53 protein does not interfere with the phosphorylation of p53 by signaling kinases. Serine 47-53 P53 Homo sapiens 66-69 18376141-3 2008 Conversely, tumor cells with low Bcl-x(L) expression and either wild type or mutant p53 are relatively cisplatin sensitive and do not exhibit such high levels of apoptosis. Cisplatin 103-112 P53 Homo sapiens 84-87 18294283-4 2008 We found that six phosphorylation sites of the Serine residues of p53 were efficiently phosphorylated in HBx-expressing ChangX-34 cells, suggesting that the binding of HBx to the p53 protein does not interfere with the phosphorylation of p53 by signaling kinases. Serine 47-53 P53 Homo sapiens 179-182 18294283-4 2008 We found that six phosphorylation sites of the Serine residues of p53 were efficiently phosphorylated in HBx-expressing ChangX-34 cells, suggesting that the binding of HBx to the p53 protein does not interfere with the phosphorylation of p53 by signaling kinases. Serine 47-53 P53 Homo sapiens 179-182 18294283-6 2008 Intriguingly, reactivation of p53 was accompanied with a nuclear accumulation of p53 and the phosphorylated p53 at Serine15 was only detected in nuclear fraction, but not in cytosolic fraction of doxorubicin-treated ChangX-34 cells. Doxorubicin 196-207 P53 Homo sapiens 30-33 18294283-6 2008 Intriguingly, reactivation of p53 was accompanied with a nuclear accumulation of p53 and the phosphorylated p53 at Serine15 was only detected in nuclear fraction, but not in cytosolic fraction of doxorubicin-treated ChangX-34 cells.

Hydrogen Peroxide 48-52 P53 Homo sapiens 89-92 18397472-6 2008 Immunoblotting revealed that the levels of p53 and p21(WAF1/CIP1) in TAM-treated cells increased in a time- and dose-dependent manner, whereas those of p27(KIP1) and p16 slightly increased or remained unchanged. Tamoxifen 69-72 P53 Homo sapiens 43-46 18397472-8 2008 These results suggest that the tumorigenic effect of TAM on MCF-7 cells arises through antitumor effects that are due to the expression of cyclin-dependent kinase inhibitors, especially p21(WAF1/CIP1) and these are regulated by the decrease of wild-type p53. Tamoxifen 53-56 P53 Homo sapiens 254-257 18425350-11 2008 Our results suggested that the PTL-induced apoptosis of A549 cells was due to the direct suppression of NF-kappaB activity in a p53- and hsp72-independent manner based on NF-kappaB signaling. parthenolide 31-34 P53 Homo sapiens 128-131 18221322-6 2008 LOH in paraffin-embedded specimens was detected in 22.6% and 12.9% for FHIT and p53 respectively.

Cisplatin 70-79 P53 Homo sapiens 121-124 18079115-6 2008 The inhibition of AMPK in those cells and in xenografts of HCT116 resulted in a remarkable increase in cisplatin-induced apoptosis, which was associated with hyper-induction of the tumor suppressor p53. Cisplatin 103-112 P53 Homo sapiens 198-201 18079115-7 2008 We further showed that ERK, but not ATM (ataxia telangiectasia mutated) and ATR (ATM- and Rad3-related) kinases, was involved in the hyper-induction of p53 by the inhibition of cisplatin-induced AMPK.

Doxorubicin 15-26 P53 Homo sapiens 41-44 18059187-5 2008 Using reporter assays, we showed that the DOX-treated hepatomas became more susceptible to rAAV2 infection in comparison to untreated controls: the permissiveness increased >350-fold and >120-fold for HepG2 (p53 wild-type) and Hep3B (p53 null) hepatomas, respectively. Doxorubicin 42-45 P53 Homo sapiens 214-217 18059187-5 2008 Using reporter assays, we showed that the DOX-treated hepatomas became more susceptible to rAAV2 infection in comparison to untreated controls: the permissiveness increased >350-fold and >120-fold for HepG2 (p53 wild-type) and Hep3B (p53 null) hepatomas, respectively. Doxorubicin 42-45 P53 Homo sapiens 240-243 18059187-7 2008 Compared to rAAV2-p53 transduction alone, rAAV2-p53 transduction with DOX resulted in a >16-fold induction of p53 expression. Doxorubicin 70-73 P53 Homo sapiens 48-51 18059187-7 2008 Compared to rAAV2-p53 transduction alone, rAAV2-p53 transduction with DOX resulted in a >16-fold induction of p53 expression. Doxorubicin 70-73 P53 Homo sapiens 48-51 18059187-11 2008 The 50% reduction in DOX administration--from 1 microM to 0.5 microM--revealed the antitumor property of the rAAV2-p53 transduction as well as the joint cytotoxicity of DOX and rAAV2-p53 against the p53-null hepatomas. Doxorubicin 21-24 P53 Homo sapiens 115-118 18059187-11 2008 The 50% reduction in DOX administration--from 1 microM to 0.5 microM--revealed the antitumor property of the rAAV2-p53 transduction as well as the joint cytotoxicity of DOX and rAAV2-p53 against the p53-null hepatomas.

Doxorubicin 21-24 P53 Homo sapiens 183-186 18059187-13 2008 Combined DOX and rAAV2-p53 administration may facilitate more efficient treatment for the HCC caused by p53 mutations. Doxorubicin 9-12 P53 Homo sapiens 104-107 18056705-2 2008 In this study, we have found that glucose depletion promotes the phosphorylation of AMP-activated protein kinase catalytic subunit alpha (AMPKalpha) in association with a significant up-regulation of p53, thereby inducing p53-dependent apoptosis in vivo and in vitro. Glucose 34-41 P53 Homo sapiens 200-203 18056705-2 2008 In this study, we have found that glucose depletion promotes the phosphorylation of AMP-activated protein kinase catalytic subunit alpha (AMPKalpha) in association with a significant up-regulation of p53, thereby inducing p53-dependent apoptosis in vivo and in vitro. Glucose 34-41 P53 Homo sapiens 222-225 18056705-5 2008 Of note, glucose deprivation led to a significant accumulation of p53 phosphorylated at Ser-46, but not at Ser-15 and Ser-20, and a transcriptional induction of p53 as well as proapoptotic p53 AIP1. Serine 88-91 P53 Homo sapiens 66-69 18056705-6 2008 Small interference RNA-mediated knockdown of p53 caused an inhibition of apoptosis following glucose depletion. Glucose 93-100 P53 Homo sapiens 45-48 18056705-8 2008 Under our experimental conditions, down-regulation of AMPKalpha caused an attenuation of p53 accumulation and its phosphorylation at Ser-46. Serine 133-136 P53 Homo sapiens 89-92 18056705-11 2008 Taken together, our present findings suggest that AMPK-dependent transcriptional induction and phosphorylation of p53 at Ser-46 play a crucial role in the induction of apoptosis under carbon source depletion. Serine 121-124 P53 Homo sapiens 114-117 18056705-11 2008 Taken together, our present findings suggest that AMPK-dependent transcriptional induction and phosphorylation of p53 at Ser-46 play a crucial role in the induction of apoptosis under carbon source depletion. Carbon 184-190 P53 Homo sapiens 114-117 18279610-1 2008 BACKGROUND & OBJECTIVE: Peptide p53(N15)Ant from the amino-terminal of p53 fused with cell penetrating peptide antennapedia (Ant) can induce rapid cell death resembling necrosis in breast cancer and pancreatic cancer, whereas it is low cytotoxic to normal cells.

Cysteine 4-12 P53 Homo sapiens 45-48 17959154-9 2008 Finally, we show that resveratrol induced ubiquitin-independent degradation of tumor suppressor gene protein p53 and inhibited p53-induced apoptosis in chondrocytes in a dose-dependent manner. Resveratrol 22-33 P53 Homo sapiens 109-112 17959154-9 2008 Finally, we show that resveratrol induced ubiquitin-independent degradation of tumor suppressor gene protein p53 and inhibited p53-induced apoptosis in chondrocytes in a dose-dependent manner. Resveratrol 22-33 P53 Homo sapiens 127-130 17959154-10 2008 Our results indicate that resveratrol seems to be an effective in vitro anti-inflammatory agent and has a chondroprotective capacity through suppression of (1) IL-1beta- (2) ROS- and (3) tumor suppressor protein p53-production. Resveratrol 26-37 P53 Homo sapiens 212-215 18281754-4 2008 Glutathione S-transferase-pi and metallo- thionein have been related to the metabolism of platinum drugs, excision repair cross-complementing 1/2 to DNA repair systems, and p53 to apoptosis. Platinum 90-98 P53 Homo sapiens 173-176 18297607-6 2008 The results also showed that the inhibition of p53 led to a resistance of the C6 cells to 20 microm Cd, decreased the apoptosis and increased the metallothioneins in these cells. Cadmium 100-102 P53 Homo sapiens 47-50 18297607-7 2008 p53 restoration increased the sensitivity of HaCaT cells to Cd but did not affect the MT expression. Cadmium 60-62 P53 Homo sapiens 0-3 17846083-5 2008 Apoptosis was prevented by the p53 inhibitor pifithrin and by p53 antisense oligonucleotides, indicating dependency of force-induced apoptosis on p53. Oligonucleotides 76-92 P53 Homo sapiens 62-65 17846083-7 2008 Prevention of calpain activation by calpeptin or antisense oligonucleotides augmented strain-induced p53 expression and transcriptional activity, resulting in a further increase of apoptotic rate. Oligonucleotides 59-75 P53 Homo sapiens 101-104 17628743-5 2008 We conclude that PARP inhibitor INO-1001 has high potential for enhancing the anti-tumor effects of chemotherapy agents such as Doxorubicin against p53 deficient breast cancer. Doxorubicin 128-139 P53 Homo sapiens 148-151 17918180-0 2008 Akt promotes cisplatin resistance in human ovarian cancer cells through inhibition of p53 phosphorylation and nuclear function. Cisplatin 13-22 P53 Homo sapiens 86-89 17918180-5 2008 Cisplatin induced apoptosis in chemosensitive, but not chemoresistant cells, and this was inhibited by downregulation of p53. Cisplatin 0-9 P53 Homo sapiens 121-124 17918180-6 2008 Cisplatin upregulated PUMA in a p53-dependent manner, and the presence of PUMA was necessary, but not sufficient for cisplatin-induced apoptosis. Cisplatin 0-9 P53 Homo sapiens 32-35 17918180-7 2008 p53 was phosphorylated on numerous N-terminal residues, including Ser15, Ser20, in response to cisplatin in chemosensitive, but not chemoresistant cells. Cisplatin 95-104 P53 Homo sapiens 0-3 17918180-8 2008 Furthermore, activation of Akt inhibited the cisplatin-induced upregulation of PUMA, and suppressed cisplatin-induced p53 phosphorylation, while inhibition of Akt increased total and phospho-p53 contents and sensitized p53 wild-type, chemoresistant cells to cisplatin-induced apoptosis. Cisplatin 45-54 P53 Homo sapiens 191-194 17918180-8 2008 Furthermore, activation of Akt inhibited the cisplatin-induced upregulation of PUMA, and suppressed cisplatin-induced p53 phosphorylation, while inhibition of Akt increased total and phospho-p53 contents and sensitized p53 wild-type, chemoresistant cells to cisplatin-induced apoptosis.

Cisplatin 100-109 P53 Homo sapiens 118-121 17918180-8 2008 Furthermore, activation of Akt inhibited the cisplatin-induced upregulation of PUMA, and suppressed cisplatin-induced p53 phosphorylation, while inhibition of Akt increased total and phospho-p53 contents and sensitized p53 wild-type, chemoresistant cells to cisplatin-induced apoptosis. Cisplatin 100-109 P53 Homo sapiens 118-121 17918180-9 2008 Finally, mutation of Ser15 and/or Ser20, but not of Ser37, to alanine significantly attenuated the ability of p53 to facilitate CDDP-induced apoptosis, and this was independent of PUMA expression. Cisplatin 128-132 P53 Homo sapiens 110-113 17918180-10 2008 These results support the hypothesis that p53 is a determinant of CDDP sensitivity, and suggest that Akt contributes to chemoresistance, in part, by attenuating p53-mediated PUMA upregulation and phosphorylation of p53, which are essential, but independent determinants of sensitivity to CDDP-induced apoptosis.

Arginine 27-30 P53 Homo sapiens 19-22 18155142-3 2008 These changes in apoptosis and p53 expression are purported to result from exposure to altered oxygen tension. Oxygen 95-101 P53 Homo sapiens 31-34 18202783-3 2008 The data obtained show that normal human lymphocytes exposed in vitro to known DNA-damaging agents, e.g. H2O2, ionizing radiation and mitomycin C, exhibit an asynchronous replication of the genes TP53 and RB1. Hydrogen Peroxide 105-109 P53 Homo sapiens 196-200 18155142-4 2008 Using a model of villous trophoblast turnover, we examined the effect of 20%, 6% and 1% ambient oxygen (O(2)) on apoptosis, necrosis, proliferation and expression of p53 and related regulators of cell turnover, compared to both fresh tissue.

Oxygen 130-134 P53 Homo sapiens 115-118 17653088-2 2008 We obtained evidence that a type of p53-dependent stress, doxorubicin (Doxo) administration, causes accumulation of p53 in the nucleus of NB cells and phosphorylation of several serine residues in both Doxo-sensitive and -resistant cell lines. Serine 178-184 P53 Homo sapiens 36-39 17637740-2 2008 We found that the cytotoxic drugs methotrexate (MTX) and 5-fluorouracil (5-FU) were both able to sensitize resistant tumor cells for induction of apoptosis by p53-mediated upregulation of caspase-8.

Doxorubicin 78-89 P53 Homo sapiens 11-14 17653088-6 2008 However, in the Doxo-resistant cells, the accumulation in the nucleus and phosphorylation of p53 did not induce p53-downstream p21(Cip1/Waf1) expression and the Noxa upregulation, resulting in the retention of the mitochondrial homeostasis.

Platinum 44-52 P53 Homo sapiens 104-108 18036557-0 2008 p53 is important for the anti-proliferative effect of ibuprofen in colon carcinoma cells. Ibuprofen 54-63 P53 Homo sapiens 0-3 18230133-13 2008 In the group of patients < or =53 yrs and with TP53(-) tumors platinum-based therapy is possibly equally efficient. Platinum 65-73 P53 Homo sapiens 50-54 18205918-8 2008 We further found stronger correlations of bFGF level and paclitaxel sensitivity in four tumor subgroups (high stage, positive p53 staining, negative aFGF staining, containing higher-than-median bFGF level), compared to all other groups. Paclitaxel 57-67 P53 Homo sapiens 126-129 18036557-4 2008 Furthermore, results indicate that induction of apoptosis in HCT-116 p53(wt) cells after ibuprofen treatment is in part dependent on a signalling pathway including the neutrophin receptor p75(NTR), p53 and Bax. Ibuprofen 89-98 P53 Homo sapiens 69-72 18036557-4 2008 Furthermore, results indicate that induction of apoptosis in HCT-116 p53(wt) cells after ibuprofen treatment is in part dependent on a signalling pathway including the neutrophin receptor p75(NTR), p53 and Bax.

Iron 50-54 P53 Homo sapiens 128-131 18042465-7 2008 Based on these results, we conclude that HO activity is involved in the regulation of p53 expression in a ROS-independent mechanism, and also suggest that the expression of p53 in ARPE-19 cells is associated with heme metabolites such as biliverdin/bilirubin, carbon monoxide, and iron produced by the activity of HO. Iron 281-285 P53 Homo sapiens 173-176 18206965-7 2008 Notably, FAK knockdown plus cisplatin triggered p53-dependent cell apoptosis, which was rescued by either full-length FAK or FAK FERM re-expression.

Resveratrol 26-28 P53 Homo sapiens 40-43 17938576-7 2008 However, nuclear localization of (64)Cu-DOTA-cetuximab showed increased uptake in the nuclei of HCT 116 +/+ cells as early as 4 h. These data demonstrate that (64)Cu is delivered to tumor cell nuclei in a p53 positive cell line in significantly greater amounts than in p53 negative cells by both non-specific and receptor-mediated uptake mechanisms. Copper 37-39 P53 Homo sapiens 205-208 17610031-13 2008 In addition, cadmium from 1 to 100 micromol/L induced the expression of p53 and phosphorylation of its Ser15 in IHH and NHH. Cadmium 13-20 P53 Homo sapiens 72-75 17938576-7 2008 However, nuclear localization of (64)Cu-DOTA-cetuximab showed increased uptake in the nuclei of HCT 116 +/+ cells as early as 4 h. These data demonstrate that (64)Cu is delivered to tumor cell nuclei in a p53 positive cell line in significantly greater amounts than in p53 negative cells by both non-specific and receptor-mediated uptake mechanisms. Copper 37-39 P53 Homo sapiens 269-272 17942461-2 2008 Exposure of cells to BPDE for up to 24 h resulted in gene expression profiles more distinguishable by duration of exposure than by p53 status, although a subset of genes were identified that had significantly different expression in p53 wild-type (WT) cells relative to p53-null cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 21-25 P53 Homo sapiens 131-134 17697133-5 2008 This suggests that WNVCp-mediated apoptosis requires p53. wnvcp 19-24 P53 Homo sapiens 53-56 18006273-0 2008 Mechanisms underlying the pro-survival pathway of p53 in suppressing mitotic death induced by adriamycin. Doxorubicin 94-104 P53 Homo sapiens 50-53 18006273-2 2008 Here we examined the pro-survival activity of p53 on the adriamycin-induced stress using H1299 cells stably expressing tsp53 V143A, a temperature-sensitive mutant activating only the subset of p53 target genes related to growth arrest and DNA repair, but not apoptosis. Doxorubicin 57-67 P53 Homo sapiens 46-49 17610031-14 2008 In conclusion, we showed in this study that human hepatocytes were sensitive to cadmium and apoptosis induced at concentrations suggested in the literature to inhibit p53 DNA-binding and DNA repair. Cadmium 80-87 P53 Homo sapiens 167-170 18519232-4 2008 Cisplatin added to the culture medium leads to the significant increase of P53 expression and decrease of BCL-2 expression. Cisplatin 0-9 P53 Homo sapiens 75-78 18791269-6 2008 In DB-1 melanoma cells that overexpress tyrosinase (Tyr(+) cells), the threshold for phosphorylation of ATM and p53 at serine 15 was observed at a low dose of Qct (25 microM) when compared to the mock transfected pcDNA3 cells, which required a higher dose (75 microM). Tyrosine 52-55 P53 Homo sapiens 112-115 18791269-6 2008 In DB-1 melanoma cells that overexpress tyrosinase (Tyr(+) cells), the threshold for phosphorylation of ATM and p53 at serine 15 was observed at a low dose of Qct (25 microM) when compared to the mock transfected pcDNA3 cells, which required a higher dose (75 microM). Serine 119-125 P53 Homo sapiens 112-115 18791269-7 2008 Both pcDNA3 and Tyr(+) DB-1 cells demonstrated similar increases in phosphorylation of p53 at other serine sites, but in the Tyr(+) cells, DNApk expression was found to be reduced compared to control cells, indicating a shift towards an ATM-mediated response. Tyrosine 16-19 P53 Homo sapiens 87-90 18791269-7 2008 Both pcDNA3 and Tyr(+) DB-1 cells demonstrated similar increases in phosphorylation of p53 at other serine sites, but in the Tyr(+) cells, DNApk expression was found to be reduced compared to control cells, indicating a shift towards an ATM-mediated response.

Adenosine Triphosphate 30-33 P53 Homo sapiens 229-232 17848574-5 2007 This reaction is driven by recycling of MDM2 from the p53 complex, triggered by binding of ATP to MDM2.

Threonine 77-80 P53 Homo sapiens 131-134 17957142-6 2007 Molecular dynamics simulations of the p53 transactivation domain suggest that phosphorylation of either Thr18 or Ser20 does not disrupt its helical structure but does result in reduced affinities for MDM2. UNII-PYZ33YLR8A 104-109 P53 Homo sapiens 38-41 17957142-9 2007 These suggest that repulsions will arise because the MDM2 surface will force the p53 to bind in a manner that will place the negatively charged phosphorylated Thr18 near this anionic region.

Fluorouracil 42-46 P53 Homo sapiens 86-89 17275163-10 2007 Because metastatic RCC frequently has p53 mutations, therapy restoring p53 may markedly improve the response rate of immunochemical therapy combining IFN-alpha and 5-FU. Fluorouracil 164-168 P53 Homo sapiens 38-41 17275163-10 2007 Because metastatic RCC frequently has p53 mutations, therapy restoring p53 may markedly improve the response rate of immunochemical therapy combining IFN-alpha and 5-FU.

Tamoxifen 72-81 P53 Homo sapiens 22-25 17646389-2 2007 Recently, we discovered that lysine methylation of p53 at K372 by Set7/9 (also known as SET7 and Set9) is important for transcriptional activation and stabilization of p53. Lysine 29-35 P53 Homo sapiens 51-54 17499351-3 2007 Unlike the tumour suppressor gene encoding p53 that is notoriously prone to inactivating mutations but whose function is essential for induction of apoptosis by DNA-targeting agents (such as doxorubicin or 5-fluorouracil), mitochondria present targets that are not so compromised by genetic mutation and whose targeting overcomes problems with mutations of upstream targets such as p53. Doxorubicin 191-202 P53 Homo sapiens 43-46 17499351-3 2007 Unlike the tumour suppressor gene encoding p53 that is notoriously prone to inactivating mutations but whose function is essential for induction of apoptosis by DNA-targeting agents (such as doxorubicin or 5-fluorouracil), mitochondria present targets that are not so compromised by genetic mutation and whose targeting overcomes problems with mutations of upstream targets such as p53. Fluorouracil 206-220 P53 Homo sapiens 43-46 17646389-2 2007 Recently, we discovered that lysine methylation of p53 at K372 by Set7/9 (also known as SET7 and Set9) is important for transcriptional activation and stabilization of p53. Lysine 29-35 P53 Homo sapiens 168-171 17646389-5 2007 Significantly, we show that lysine methylation of p53 is important for its subsequent acetylation, resulting in stabilization of the p53 protein.

Lysine 28-34 P53 Homo sapiens 133-136 17951408-3 2007 The down-regulated expression of hOGG1 by its small interfering RNA prominently triggers the H(2)O(2)-induced apoptosis in human fibroblasts GM00637 and human lung carcinoma H1299 cells via the p53-mediated apoptotic pathway. Hydrogen Peroxide 93-101 P53 Homo sapiens 194-197 17646389-8 2007 Collectively, these results suggest that the cross talk between lysine methylation and acetylation is critical for p53 activation in response to DNA damage and that Set7/9 may play an important role in tumor suppression. Lysine 64-70 P53 Homo sapiens 115-118 17951408-5 2007 The p53-small interfering RNA transfection into the hOGG1-deficient GM00637 markedly inhibited the H(2)O(2)-induced activation of p53-downstream target proteins such as p21, Noxa, and caspase-3/7, which eventually resulted in the increased cell viability. gm00637 68-75 P53 Homo sapiens 4-7 17951408-5 2007 The p53-small interfering RNA transfection into the hOGG1-deficient GM00637 markedly inhibited the H(2)O(2)-induced activation of p53-downstream target proteins such as p21, Noxa, and caspase-3/7, which eventually resulted in the increased cell viability. gm00637 68-75 P53 Homo sapiens 130-133 17666403-3 2007 CHIP preferentially binds to the p53 mutant phenotype and restored the DNA binding activity of heat-denatured p53 in an ATP-independent manner.

Hydrogen Peroxide 99-107 P53 Homo sapiens 130-133 17951408-8 2007 Therefore, we suggest that although p53 is a major modulator of apoptosis, hOGG1 also plays a pivotal role in protecting cells against the H(2)O(2)-induced apoptosis at the upstream of the p53-dependent pathway to confer a survival advantage to human fibroblasts and human lung carcinomas through maintaining their genomic stability.

Irinotecan 0-5 P53 Homo sapiens 16-19 17666793-10 2007 SN-38-induced P-gp expression was additionally enhanced by p53 decoy oligodeoxynucleotide. Irinotecan 0-5 P53 Homo sapiens 59-62 17585903-4 2007 As a result, methyl 2,5-dihydromethylcinnimate (2,5-MeC), a tyrosine kinase inhibitor, enhanced expression and/or stability of PML proteins and induced PML-NB formation in p53 null H1299 cells established from non-small cell lung cancer (NSCLC) and wild-type p53-expressing U2OS cells derived from osteosarcoma. methyl 2,5-dihydromethylcinnimate 13-46 P53 Homo sapiens 172-175 17585903-4 2007 As a result, methyl 2,5-dihydromethylcinnimate (2,5-MeC), a tyrosine kinase inhibitor, enhanced expression and/or stability of PML proteins and induced PML-NB formation in p53 null H1299 cells established from non-small cell lung cancer (NSCLC) and wild-type p53-expressing U2OS cells derived from osteosarcoma. methyl 2,5-dihydromethylcinnimate 13-46 P53 Homo sapiens 259-262 17392828-6 2007 DeltaNp63alpha also induces apoptosis in HaCaT and SCC-13 cells, which encode inactive p53 genes, suggesting that the response is p53 independent in these cell lines. deltanp63alpha 0-14 P53 Homo sapiens 87-90 17914225-4 2007 By computing the free energies of wild-type and mutant p53c binding to DNA and decomposing them into contributions from individual residues, the DNA-binding loss upon charge/noncharge -conserving mutation of Arg 273 was attributed not only to the loss of DNA phosphate contacts, but also to longer-range structural changes caused by the loss of the Asp 281 salt-bridge. Arginine 208-211 P53 Homo sapiens 55-58 17914225-4 2007 By computing the free energies of wild-type and mutant p53c binding to DNA and decomposing them into contributions from individual residues, the DNA-binding loss upon charge/noncharge -conserving mutation of Arg 273 was attributed not only to the loss of DNA phosphate contacts, but also to longer-range structural changes caused by the loss of the Asp 281 salt-bridge. Phosphates 259-268 P53 Homo sapiens 55-58 17914225-5 2007 The results herein and in previous works suggest that Asp 281 plays a critical role in the sequence-specific DNA-binding function of p53c by (i)orienting Arg 273 and Arg 280 in an optimal position to interact with the phosphate and base groups of the consensus DNA, respectively, and (ii) helping to maintain the proper DNA-binding protein conformation. Arginine 154-157 P53 Homo sapiens 133-136 17914225-5 2007 The results herein and in previous works suggest that Asp 281 plays a critical role in the sequence-specific DNA-binding function of p53c by (i)orienting Arg 273 and Arg 280 in an optimal position to interact with the phosphate and base groups of the consensus DNA, respectively, and (ii) helping to maintain the proper DNA-binding protein conformation. Arginine 166-169 P53 Homo sapiens 133-136 17914225-5 2007 The results herein and in previous works suggest that Asp 281 plays a critical role in the sequence-specific DNA-binding function of p53c by (i)orienting Arg 273 and Arg 280 in an optimal position to interact with the phosphate and base groups of the consensus DNA, respectively, and (ii) helping to maintain the proper DNA-binding protein conformation. Phosphates 218-227 P53 Homo sapiens 133-136 17392828-6 2007 DeltaNp63alpha also induces apoptosis in HaCaT and SCC-13 cells, which encode inactive p53 genes, suggesting that the response is p53 independent in these cell lines. deltanp63alpha 0-14 P53 Homo sapiens 130-133 17070097-6 2007 In addition, cotreatment with the AHR antagonist, 3"-methoxy-4"-nitroflavone (MNF) blocked the effects of TCDD and CSC on p53 and CYP1A1 expression. Polychlorinated Dibenzodioxins 106-110 P53 Homo sapiens 122-125 17616157-4 2007 Using these modified SP microarrays, enhancement factors of 229 and 126 were obtained for prostate-specific antigen (PSA) and p53 oligonucleotide detection, respectively. Oligonucleotides 130-145 P53 Homo sapiens 126-129 17070096-7 2007 Mutational analysis of p53 gene revealed an A-->G transition at the second base of codon 220, resulting in amino acid substitution from tyrosine to cysteine in the protein. Tyrosine 139-147 P53 Homo sapiens 23-26 17070096-7 2007 Mutational analysis of p53 gene revealed an A-->G transition at the second base of codon 220, resulting in amino acid substitution from tyrosine to cysteine in the protein. Cysteine 151-159 P53 Homo sapiens 23-26 17070097-5 2007 A role of the AHR in mediating these events is indicated by the observations that the TCDD and CSC-induced decreases in p15(INK4b), p16(INK4a) and p53 expression was accompanied by a corresponding increase in the expression levels of the AHR target gene, CYP1A1. Polychlorinated Dibenzodioxins 86-90 P53 Homo sapiens 147-150 17668048-1 2007 Tumor suppressor SMAR1 interacts and stabilizes p53 through phosphorylation at its serine-15 residue. Serine 83-89 P53 Homo sapiens 48-51 17668048-3 2007 Upon Doxorubicin induced DNA damage, acetylated p53 is recruited on SMAR1 promoter that allows activation of its transcription. Doxorubicin 5-16 P53 Homo sapiens 48-51 17668048-4 2007 Once SMAR1 is induced, cell cycle arrest is observed that is correlated to increased phospho-ser-15-p53 and decreased p53 acetylation. Serine 46-49 P53 Homo sapiens 100-103 17668048-4 2007 Once SMAR1 is induced, cell cycle arrest is observed that is correlated to increased phospho-ser-15-p53 and decreased p53 acetylation.

Oxygen 49-55 P53 Homo sapiens 142-145 17616578-2 2007 Here we show that transcription-blocking agents can induce phosphorylation of the Ser-15 site of p53 in a replication-independent manner. Serine 82-85 P53 Homo sapiens 97-100 17616578-5 2007 First, accumulation of p53 is linked to diminished nuclear export of mRNA; and second, inhibition specifically of elongating RNA polymerase II complexes results in the phosphorylation of the Ser-15 site of p53 in a replication protein A (RPA)- and ATM and Rad3-related (ATR)-dependent manner. Serine 191-194 P53 Homo sapiens 23-26 17616578-5 2007 First, accumulation of p53 is linked to diminished nuclear export of mRNA; and second, inhibition specifically of elongating RNA polymerase II complexes results in the phosphorylation of the Ser-15 site of p53 in a replication protein A (RPA)- and ATM and Rad3-related (ATR)-dependent manner. Serine 191-194 P53 Homo sapiens 206-209 17512204-6 2007 The activation of DNA damage response as indicated by phosphorylation of H2AX histone, RPA-2 protein, and p53 at serine 15 by the most apoptotic compounds provides additional support to the hypothesis that the genotoxic stress is a critical event mediating apoptosis induction by compounds of this group. Serine 113-119 P53 Homo sapiens 106-109 17297446-4 2007 Although p53 stabilization and phosphorylation at serine 15 increased with dose and time of exposure, Mdm2 and p21(CIP1/WAF1) protein levels displayed a biphasic response, as they accumulated at submicromolar doses and then decreased with increasing AF. Serine 50-56 P53 Homo sapiens 9-12 17498666-7 2007 Cisplatin also inhibited the synthesis of HIF-1alpha protein for which p53 was dispensable. Cisplatin 0-9 P53 Homo sapiens 71-74 17630506-1 2007 p53 ubiquitination at C-terminal lysines by MDM2 and other E3 ligases had been considered a straightforward negative regulation of p53 with only one function, that is marking the protein for proteasomal degradation. Lysine 33-40 P53 Homo sapiens 0-3 17630506-1 2007 p53 ubiquitination at C-terminal lysines by MDM2 and other E3 ligases had been considered a straightforward negative regulation of p53 with only one function, that is marking the protein for proteasomal degradation. Lysine 33-40 P53 Homo sapiens 131-134 17634554-10 2007 Levels of both the acetylated and phosphorylated forms of p53 were markedly increased upon doxorubicin exposure when compared with treatment with 5-FU, resulting in a significantly prolonged half-life of p53 (120 versus 20 min). Doxorubicin 91-102 P53 Homo sapiens 58-61 17634554-10 2007 Levels of both the acetylated and phosphorylated forms of p53 were markedly increased upon doxorubicin exposure when compared with treatment with 5-FU, resulting in a significantly prolonged half-life of p53 (120 versus 20 min).

Fluorouracil 100-114 P53 Homo sapiens 70-73 17634554-10 2007 Levels of both the acetylated and phosphorylated forms of p53 were markedly increased upon doxorubicin exposure when compared with treatment with 5-FU, resulting in a significantly prolonged half-life of p53 (120 versus 20 min). Fluorouracil 146-150 P53 Homo sapiens 204-207 17634554-1 2007 PURPOSE: The purpose of the study is to investigate the regulation of p53 expression in response to 5-fluorouracil (5-FU) in human colon cancer cells. Fluorouracil 116-120 P53 Homo sapiens 70-73 17630511-1 2007 The p53 tumor suppressor is a mutational target of environmental carcinogen anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 81-117 P53 Homo sapiens 4-7 17634554-3 2007 The levels of p53 expression and p53 protein stability in response to 5-FU and doxorubicin were investigated. Fluorouracil 70-74 P53 Homo sapiens 14-17 17634554-13 2007 Studies are under way to define the specific mechanism(s) that control 5-FU-mediated translational regulation of p53. Fluorouracil 71-75 P53 Homo sapiens 113-116 17630511-1 2007 The p53 tumor suppressor is a mutational target of environmental carcinogen anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 119-123 P53 Homo sapiens 4-7 17634554-3 2007 The levels of p53 expression and p53 protein stability in response to 5-FU and doxorubicin were investigated. Doxorubicin 79-90 P53 Homo sapiens 14-17 17634554-4 2007 In addition, the acetylation and phosphorylation status of p53 after 5-FU and doxorubicin treatment was analyzed by Western immunoblot analysis. Fluorouracil 69-73 P53 Homo sapiens 59-62 17634554-4 2007 In addition, the acetylation and phosphorylation status of p53 after 5-FU and doxorubicin treatment was analyzed by Western immunoblot analysis. Doxorubicin 78-89 P53 Homo sapiens 59-62 17634554-5 2007 RESULTS: Treatment of human colon cancer RKO cells with 10 micromol/L 5-FU resulted in significantly increased levels of p53 protein with maximal induction observed at 24 h. The level of acetylated p53 after 5-FU exposure remained unchanged, whereas the phosphorylated form of p53 was expressed only after 24 h drug treatment. Fluorouracil 70-74 P53 Homo sapiens 121-124 17638885-0 2007 Systemic treatment with the antidiabetic drug metformin selectively impairs p53-deficient tumor cell growth. Metformin 46-55 P53 Homo sapiens 76-79 17638885-2 2007 Treatment with metformin selectively suppressed the tumor growth of HCT116 p53(-/-) xenografts. Metformin 15-24 P53 Homo sapiens 75-78 17630511-2 2007 We now demonstrate that p53 plays an important role in regulation of cellular responses to BPDE. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 91-95 P53 Homo sapiens 24-27 17638885-3 2007 Following treatment with metformin, we detected increased apoptosis in p53(-/-) tumor sections and an enhanced susceptibility of p53(-/-) cells to undergo apoptosis in vitro when subject to nutrient deprivation. Metformin 25-34 P53 Homo sapiens 71-74 17638885-3 2007 Following treatment with metformin, we detected increased apoptosis in p53(-/-) tumor sections and an enhanced susceptibility of p53(-/-) cells to undergo apoptosis in vitro when subject to nutrient deprivation. Metformin 25-34 P53 Homo sapiens 129-132 17634554-5 2007 RESULTS: Treatment of human colon cancer RKO cells with 10 micromol/L 5-FU resulted in significantly increased levels of p53 protein with maximal induction observed at 24 h. The level of acetylated p53 after 5-FU exposure remained unchanged, whereas the phosphorylated form of p53 was expressed only after 24 h drug treatment. Fluorouracil 70-74 P53 Homo sapiens 198-201 17634554-5 2007 RESULTS: Treatment of human colon cancer RKO cells with 10 micromol/L 5-FU resulted in significantly increased levels of p53 protein with maximal induction observed at 24 h. The level of acetylated p53 after 5-FU exposure remained unchanged, whereas the phosphorylated form of p53 was expressed only after 24 h drug treatment. Fluorouracil 70-74 P53 Homo sapiens 198-201 17638885-8 2007 Treatment with either metformin or AICAR also led to enhanced fatty acid beta-oxidation in p53(+/+) MEFs, but not in p53(-/-) MEFs. Metformin 22-31 P53 Homo sapiens 91-94 17630511-6 2007 The H460 human lung cancer cell line (wild-type p53) was relatively more sensitive to BPDE-mediated growth inhibition and enrichment of sub-diploid apoptotic fraction compared with H1299 cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 86-90 P53 Homo sapiens 48-51 17638885-8 2007 Treatment with either metformin or AICAR also led to enhanced fatty acid beta-oxidation in p53(+/+) MEFs, but not in p53(-/-) MEFs. Fatty Acids 62-72 P53 Homo sapiens 91-94 17634554-5 2007 RESULTS: Treatment of human colon cancer RKO cells with 10 micromol/L 5-FU resulted in significantly increased levels of p53 protein with maximal induction observed at 24 h. The level of acetylated p53 after 5-FU exposure remained unchanged, whereas the phosphorylated form of p53 was expressed only after 24 h drug treatment. Fluorouracil 208-212 P53 Homo sapiens 198-201 17634554-5 2007 RESULTS: Treatment of human colon cancer RKO cells with 10 micromol/L 5-FU resulted in significantly increased levels of p53 protein with maximal induction observed at 24 h. The level of acetylated p53 after 5-FU exposure remained unchanged, whereas the phosphorylated form of p53 was expressed only after 24 h drug treatment. Fluorouracil 208-212 P53 Homo sapiens 198-201 17638885-10 2007 Metformin-treated cells compensated for this suppression of oxidative phosphorylation by increasing their rate of glycolysis in a p53-dependent manner. Metformin 0-9 P53 Homo sapiens 130-133 17630511-8 2007 Instead, the BPDE-treated H460 cells exhibited a nearly 8-fold increase in sub-diploid apoptotic cells that was accompanied by phosphorylation of p53 at multiple sites. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 13-17 P53 Homo sapiens 146-149 17638885-11 2007 Together, these data suggest that metformin treatment forces a metabolic conversion that p53(-/-) cells are unable to execute. Metformin 34-43 P53 Homo sapiens 89-92 17638885-12 2007 Thus, metformin is selectively toxic to p53-deficient cells and provides a potential mechanism for the reduced incidence of tumors observed in patients being treated with metformin. Metformin 6-15 P53 Homo sapiens 40-43 17630511-9 2007 Knockdown of p53 protein level in H460 cells attenuated BPDE-induced apoptosis but enforced activation of S and G(2) phase checkpoints. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 56-60 P53 Homo sapiens 13-16 17638885-12 2007 Thus, metformin is selectively toxic to p53-deficient cells and provides a potential mechanism for the reduced incidence of tumors observed in patients being treated with metformin. Metformin 171-180 P53 Homo sapiens 40-43 17630511-10 2007 In conclusion, the present study points towards an important role of p53 in regulation of cellular responses to BPDE in human lung cancer cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 112-116 P53 Homo sapiens 69-72 17509529-2 2007 KCG165-induced phosphorylations of p53 at Ser(6), Ser(15), and Ser(20)(,) which are all key residues involved in the activation and stabilization of p53. Serine 42-45 P53 Homo sapiens 35-38 17634554-7 2007 No differences were observed in the half-life of p53 protein in control and 5-FU-treated cells, suggesting that the increase in p53 was the direct result of newly synthesized protein. Fluorouracil 76-80 P53 Homo sapiens 128-131 17634554-8 2007 In contrast, the maximal induction of p53, in response to doxorubicin, occurred at an earlier time point (4 h) when compared with cells treated with 5-FU (24 h). Doxorubicin 58-69 P53 Homo sapiens 38-41 17509529-2 2007 KCG165-induced phosphorylations of p53 at Ser(6), Ser(15), and Ser(20)(,) which are all key residues involved in the activation and stabilization of p53. Serine 50-53 P53 Homo sapiens 35-38 17509529-2 2007 KCG165-induced phosphorylations of p53 at Ser(6), Ser(15), and Ser(20)(,) which are all key residues involved in the activation and stabilization of p53. Serine 50-53 P53 Homo sapiens 35-38 17555331-0 2007 Human p53 is inhibited by glutathionylation of cysteines present in the proximal DNA-binding domain during oxidative stress. Cysteine 47-56 P53 Homo sapiens 6-9 17555331-3 2007 First, a rapid and direct incorporation of biotinylated GSH or GSSG into the purified recombinant p53 protein was observed. Glutathione 56-59 P53 Homo sapiens 98-101 17555331-6 2007 GSH modification coexisted with the serine phophorylations in activated p53, and the thiol-conjugated protein was present in nuclei. Glutathione 0-3 P53 Homo sapiens 72-75 17555331-6 2007 GSH modification coexisted with the serine phophorylations in activated p53, and the thiol-conjugated protein was present in nuclei. Serine 36-42 P53 Homo sapiens 72-75 17555331-7 2007 When tumor cells treated with camptothecin or cisplatin were subsequently exposed to glutathione-enhancing agents, p53 underwent dethiolation accompanied by detectable increases in the level of p21waf1 expression, relative to the DNA-damaging drugs alone. Cisplatin 46-55 P53 Homo sapiens 115-118 17555331-7 2007 When tumor cells treated with camptothecin or cisplatin were subsequently exposed to glutathione-enhancing agents, p53 underwent dethiolation accompanied by detectable increases in the level of p21waf1 expression, relative to the DNA-damaging drugs alone. Glutathione 85-96 P53 Homo sapiens 115-118 17555331-8 2007 Mass spectrometry of GSH-modified p53 protein identified cysteines 124, 141, and 182, all present in the proximal DNA-binding domain, as the sites of glutathionylation. Glutathione 21-24 P53 Homo sapiens 34-37 17555331-8 2007 Mass spectrometry of GSH-modified p53 protein identified cysteines 124, 141, and 182, all present in the proximal DNA-binding domain, as the sites of glutathionylation. Cysteine 57-66 P53 Homo sapiens 34-37 17555331-9 2007 Biotinylated maleimide also reacted rapidly with Cys141, implying that this is the most reactive cysteine on the p53 surface. Cysteine 97-105 P53 Homo sapiens 113-116 17555331-10 2007 The glutathionylatable cysteines were found to exist in a negatively charged microenvironment in cellular p53. Cysteine 23-32 P53 Homo sapiens 106-109 17555331-12 2007 These results show for the first time that shielding of reactive cysteines contributes to a negative regulation for human p53 and imply that such an inactivation of the transcription factor may represent an acute defensive response with significant consequences for oncogenesis. Cysteine 65-74 P53 Homo sapiens 122-125 17413032-7 2007 Increases in p53 phosphorylation on Ser-15 were observed in both SARS-CoV M and 3a transfected cells, suggesting that it might not correlate with the 3a-induced G0/G1 phase arrest. Serine 36-39 P53 Homo sapiens 13-16 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Eflornithine 82-111 P53 Homo sapiens 129-132 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Eflornithine 82-111 P53 Homo sapiens 323-326 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Eflornithine 82-111 P53 Homo sapiens 323-326 17356895-6 2007 However, the RCMF-induced apoptosis was suppressed by transfecting the cells with antisense p53 oligonucleotides but not by treating them with a MAPK or caspase inhibitor.

Doxorubicin 114-124 P53 Homo sapiens 157-160 17630850-13 2007 Translocation of p53 from the cytosol to the nucleus occurred with a maximal increase of 2.9-fold in the nucleus following 1.0 mM GSNO for 24 h. These data indicate that in cardiomyocytes, NO induced marked DNA damage and translocation of p53 to the nucleus, suggesting that p53 is involved in the cellular response to NO, perhaps to modulate the genomic response to NO-induced cellular toxicity.

Serine 41-47 P53 Homo sapiens 19-22 17567683-6 2007 Under mild or severe H2O2-induced stress, p53-deficient SiHa cells exhibited much higher ROS levels than control SiHa cells. ros 89-92 P53 Homo sapiens 42-45 17567683-7 2007 Furthermore, we analyzed cell viability and apoptosis after H2O2 treatment and found that p53 deficiency sensitized SiHa cells to H2O2 damage. Hydrogen Peroxide 60-64 P53 Homo sapiens 90-93 17567683-7 2007 Furthermore, we analyzed cell viability and apoptosis after H2O2 treatment and found that p53 deficiency sensitized SiHa cells to H2O2 damage. Hydrogen Peroxide 130-134 P53 Homo sapiens 90-93 17567683-8 2007 Inhibition of p53 resulted in excessive oxidation of DNA; control SiHa cells exhibited a more rapid removal of 8-oxo-7,8-dihydro-2"-deoxyguanosine from DNA compared with p53-deficient SiHa cells exposed to the same level of H2O2 challenge. Hydrogen Peroxide 224-228 P53 Homo sapiens 14-17 17690521-6 2007 In the medium and high exposure groups, the incidence and/or quantity of mutant p53 protein in the stratum of PG II and/or III were significantly higher than that of PG I (p<0.05). pg ii 110-115 P53 Homo sapiens 80-83 17596214-6 2007 Curcumin reduced cell survival in a p53- and caspase-independent manner, an effect correlated with the inhibition of AP-1 and NFkappaB signaling pathways via prevention of constitutive JNK and Akt activation. Curcumin 0-8 P53 Homo sapiens 36-39 17703463-4 2007 Using a combination of rigid-body protein docking, experimental mutagenesis information, and cluster analysis 10 main p53 DBD-AZ binding modes were generated. dbd-az 122-128 P53 Homo sapiens 118-121 17395767-7 2007 In chromatin immunoprecipitation experiments, BeSO(4) caused p53 protein to associate with its DNA binding site in the promoter region of the p21 gene, indicating that p53 transcriptional activity is responsible for the large increase in p21 mRNA elicited by beryllium. Beryllium 259-268 P53 Homo sapiens 61-64 17703463-6 2007 We found that the highest scored docking conformation for the p53 DBD-AZ complex also yielded the most favorable free energy value. dbd-az 66-72 P53 Homo sapiens 62-65 17609585-6 2007 SN-38 binding motifs were detected in the proximal promoter of p53 (bases -433 to -317 and -814 to -711). Irinotecan 0-5 P53 Homo sapiens 63-66 17609585-0 2007 Irinotecan activates p53 with its active metabolite, resulting in human hepatocellular carcinoma apoptosis. Irinotecan 0-10 P53 Homo sapiens 21-24 17609585-7 2007 These results suggest that the p53-mediated apoptosis pathway is important in the anticancer effects of irinotecan in hepatocellular carcinoma. Irinotecan 104-114 P53 Homo sapiens 31-34 17609585-4 2007 SN-38 significantly increased the expression of p53 protein and its phosphorylation at Ser(15) in the nucleus and apoptosis-inducing proteins Bax, caspase-9, and caspase-3, while it significantly decreased the antiapoptosis protein Bcl-xL of Huh7 cells.

Alanine 13-20 P53 Homo sapiens 50-55 17609585-5 2007 SN-38-induced apoptosis was recovered after p53 antisense oligodeoxynucleotide (AS ODN) pretreatment, while Huh7 cells were precultured with p53 AS ODN, followed by the addition of SN-38 for 24 h. Furthermore, increases in p53 DNA-binding activity were observed in the nuclei of Huh7 cells after SN-38 treatment as shown by electrophoretic mobility shift analysis. Irinotecan 0-5 P53 Homo sapiens 44-47 17609585-5 2007 SN-38-induced apoptosis was recovered after p53 antisense oligodeoxynucleotide (AS ODN) pretreatment, while Huh7 cells were precultured with p53 AS ODN, followed by the addition of SN-38 for 24 h.

Furthermore, increases in p53 DNA-binding activity were observed in the nuclei of Huh7 cells after SN-38 treatment as shown by electrophoretic mobility shift analysis. Irinotecan 0-5 P53 Homo sapiens 141-144 17393435-0 2007 A plant lignan, 3"-O-methyl-nordihydroguaiaretic acid, suppresses papillomavirus E6 protein function, stabilizes p53 protein, and induces apoptosis in cervical tumor cells. Lignans 8-14 P53 Homo sapiens 113-116 17393435-12 2007 These results indicate that the loss of E6 protein in treated cells could be, in part, responsible for the stabilization of p53 within the lignan treated cells. Lignans 139-145 P53 Homo sapiens 124-127 17334779-7 2007 Ser(15) phosphorylation of p53 was increased by anoxia in an NHE- and p38 MAPK-independent manner, while Akt activity was unaffected. Serine 0-3 P53 Homo sapiens 27-30 17913962-8 2007 The effect of ET-1 on apoptosis in 20% oxygen is accompanied by reduced p53 expression and is correlated with enhanced expression of endothelin B receptor, compared to cultures in 8% or 1% oxygen. Oxygen 39-45 P53 Homo sapiens 72-75 17466278-2 2007 Previous study in our laboratory considered p53 mutant cell lines A431 (parental) and A431/Pt (CDDP-resistant counterpart, resistance factor R.F.=2.6). cddp 95-99 P53 Homo sapiens 44-47 17466278-12 2007 The presence of a wild-type p53 exalts either CDDP cytotoxicity (two-fold more active in U2-OS than in A431 cells) and CDDP resistance in comparison to a p53 mutant type. cddp 46-50 P53 Homo sapiens 28-31 17466278-12 2007 The presence of a wild-type p53 exalts either CDDP cytotoxicity (two-fold more active in U2-OS than in A431 cells) and CDDP resistance in comparison to a p53 mutant type. cddp 119-123 P53 Homo sapiens 28-31 17585201-3 2007 p21 knockdown by short hairpin RNA strongly increased p53 upregulation by a DNA-damaging drug doxorubicin in HT1080 fibrosarcoma cells. Doxorubicin 94-105 P53 Homo sapiens 54-57 17530771-4 2007 After treatment with propolin H in H460 cells, the content of the CDK inhibitor p21Waf1/Cip1 protein increased in correlation with the elevation in p53 levels. propolin H 21-31 P53 Homo sapiens 148-151 17530771-7 2007 Additionally, we found that propolin H enhanced the expression of p21Waf1/Cip1 in p53-mutant and p53-null lung carcinoma cell lines, following the induction of G1 arrest. propolin H 28-38 P53 Homo sapiens 82-85 17530771-7 2007 Additionally, we found that propolin H enhanced the expression of p21Waf1/Cip1 in p53-mutant and p53-null lung carcinoma cell lines, following the induction of G1 arrest. propolin H 28-38 P53 Homo sapiens 97-100 17530771-8 2007 Together, these findings suggest that the induction of p21Waf1/Cip1 expression occurred through p53-dependent and -independent pathways in propolin H-treated cells. propolin H 139-149 P53 Homo sapiens 96-99 17452332-8 2007 Thus, our results strongly suggest that the nuclear IKK-alpha-mediated accumulation of p73alpha is one of the novel molecular mechanisms to induce apoptotic cell death in response to CDDP, which may be particularly important in killing tumor cells with p53 mutation. Cisplatin 183-187 P53 Homo sapiens 253-256 17530733-2 2007 DMC was previously shown in our laboratory to exceed the cytotoxicity of MC in a human leukemia cell line that lacks a functional p53 pathway (K562). 10-decarbamoylmitomycin C 0-3 P53 Homo sapiens 130-133 17530733-5 2007 In cell lines lacking wild-type p53, DMC was reproducibly more cytotoxic than MC, but it generated barely detectable signal transduction markers associated with apoptotic death. 10-decarbamoylmitomycin C 37-40 P53 Homo sapiens 32-35 17530733-7 2007 Alkylating agents can induce increased PARP activity associated with programmed necrosis, and the biological activity of DMC in p53-null cell lines fits this paradigm. 10-decarbamoylmitomycin C 121-124 P53 Homo sapiens 128-131 17530733-8 2007 In cell lines with a functional p53 pathway, both MC and DMC induced apoptosis. 10-decarbamoylmitomycin C 57-60 P53 Homo sapiens 32-35 17530733-9 2007 In the presence of p53, both MC and DMC activate procaspases; however, the spectrum of procaspases involved differs for the two drugs, as does induction of p73. 10-decarbamoylmitomycin C 36-39 P53 Homo sapiens 19-22 17492690-2 2007 The TP53 polymorphism, in which an arginine (R) is changed to proline (P) at codon 72, is functionally significant and could therefore be a predisposing genetic defect. Arginine 35-43 P53 Homo sapiens 4-8 17585201-4 2007 A protease inhibitor N-Ac-Leu-Leu-norleucinal (ALLN) drastically increased the amount of p53 in HCT116 colon carcinoma cells, but it had no effect on the already high p53 level in a p21(-/-) derivative of this cell line. 1-AMINO-1-CARBONYL PENTANE 34-45 P53 Homo sapiens 89-92 17535973-5 2007 The overall 12-yr survival was increased in p53 Arg/Pro heterozygotes with 3% (P = 0.003) and in Pro/Pro homozygotes with 6% (P = 0.002) versus Arg/Arg homozygotes, corresponding to an increase in median survival of 3 yr for Pro/Pro versus Arg/Arg homozygotes. Arginine 48-51 P53 Homo sapiens 44-47 17512465-3 2007 However, the results from the present study suggest that busulfan (BU), an alkylating agent that causes DNA damage by cross-linking DNAs and DNA and proteins, induces senescence in normal human diploid WI38 fibroblasts through the extracellular signal-regulated kinase (Erk) and p38 mitogen-activated protein kinase (p38 MAPK) cascade independent of the p53-DNA damage pathway. Busulfan 57-65 P53 Homo sapiens 354-357 17512465-3 2007 However, the results from the present study suggest that busulfan (BU), an alkylating agent that causes DNA damage by cross-linking DNAs and DNA and proteins, induces senescence in normal human diploid WI38 fibroblasts through the extracellular signal-regulated kinase (Erk) and p38 mitogen-activated protein kinase (p38 MAPK) cascade independent of the p53-DNA damage pathway. Busulfan 67-69 P53 Homo sapiens 354-357 16973168-4 2007 The high-arsenic exposure group with GSTP1 variant genotypes of Ile/Val and Val/Val, and with the p53 variant genotypes of Arg/Pro and Pro/Pro had 6.0- and 3.1-fold higher risks of carotid atherosclerosis, respectively. Arginine 123-126 P53 Homo sapiens 98-101 17113707-9 2007 Present findings indicate occurrence of sensitization to cisplatin by zoledronic acid in wild-type p53 osteosarcoma cells but not in p53-null cells nor in cells expressing a dominant-negative form of p53, supporting that wild-type p53 is required for synergistic interaction of cisplatin and zoledronic acid. Cisplatin 57-66 P53 Homo sapiens 99-102 17369602-0 2007 p-53 gene mutations as a predictive marker in a population of advanced breast cancer patients randomly treated with doxorubicin or docetaxel in the context of a phase III clinical trial. Doxorubicin 116-127 P53 Homo sapiens 0-4 17369602-1 2007 BACKGROUND: Preclinical data indicate that p-53 gene mutations predict resistance to doxorubicin (A) but not to docetaxel (Taxotere) (T). Doxorubicin 85-96 P53 Homo sapiens 43-47 17369602-11 2007 Of the 16 patients carrying wild-type p-53- and topo II protein-positive tumors, seven (44%) responded to anthracyclines, while response rate to the same drug was 13% in the remaining cohorts [odds ratio 5.06 (95% confidence interval 1.19-21.41), P = 0.03]. Anthracyclines 106-120 P53 Homo sapiens 38-55 17395471-0 2007 Novel morpholin-3-one derivatives induced apoptosis and elevated the level of P53 and Fas in A549 lung cancer cells. Morpholin-3-one 6-21 P53 Homo sapiens 78-81 17395471-4 2007 The results showed that the morpholin-3-one derivatives partly blocked the cells at G1 phase, induced apoptosis, and elevated the level of P53 and Fas proteins significantly. Morpholin-3-one 28-43 P53 Homo sapiens 139-142 17307334-4 2007 In this study, we found that TAM treatment of MDA-MB-361 breast cancer cells activated p21Waf1/Cip1 gene transcription independently of p53. Tamoxifen 29-32 P53 Homo sapiens 136-139 17514353-5 2007 Buffering of the calcium response attenuated mitochondrial impairment, recovered the cadmium-activated Akt, p53, JNK, ERK and p38, and subsequently blocked the apoptosis. Calcium 17-24 P53 Homo sapiens 108-111 17321721-4 2007 CsA induced p21WAF1/Cip1 expression de novo in human glioblastoma cells with p53 deficiency. Cyclosporine 0-3 P53 Homo sapiens 77-80 17321721-9 2007 It suggests that CsA activates p53-independent, transcriptional activation p21WAF1/Cip1 expression, mediated by ERK/c-Jun/AP-1 signaling pathway. Cyclosporine 17-20 P53 Homo sapiens 31-34 17534149-6 2007 We and others have recently identified a novel modification on p53, acetylation of lysine 120 within the DNA binding domain. Lysine 83-89 P53 Homo sapiens 63-66 17514353-0 2007 Calcium-mediated activation of PI3K and p53 leads to apoptosis in thyroid carcinoma cells. Calcium 0-7 P53 Homo sapiens 40-43 17534149-8 2007 We demonstrate here that both the DNA damage response pathway and the p19ARF/oncogene stress pathway induce the acetylation of p53 at lysine 120. Lysine 134-140 P53 Homo sapiens 127-130 17514353-3 2007 Cadmium caused the rapid elevation of intracellular calcium and induced phosphorylation of Akt, p53, JNK, ERK and p38. Cadmium 0-7 P53 Homo sapiens 96-99 17545634-4 2007 Moreover, in MCF-7 human breast cancer cells, various p53-inducing agents (such as UV irradiation) or treatment with RITA (which inhibits the interaction of p53 with Mdm2) stabilized ERalpha and abolished its 17beta-estradiol-dependent turnover.

Serine 71-74 P53 Homo sapiens 48-51 17180249-10 2007 In addition, the percentage of Ser 392 phosphorylated form of p53 protein was lower in meningiomas and other brain tumor types irrespective of tumor grade. Serine 31-34 P53 Homo sapiens 62-65 17180249-11 2007 These results suggest involvement of Ser 392 phosphorylated form of p53 protein during the later stages of glioma development. Serine 37-40 P53 Homo sapiens 68-71 17371838-5 2007 Levels of binding of p53 to the p21 promoter were comparable following treatment with doxorubicin or Mdm2 siRNA.

Reactive Oxygen Species 24-27 P53 Homo sapiens 109-112 17371868-5 2007 Mutant p53 ubiquitination occurred at lysines in both the DNA-binding domain (DBD) and C terminus. Lysine 38-45 P53 Homo sapiens 7-10 17371868-6 2007 Interestingly, Lys to Arg mutations that inhibited ubiquitination restored nuclear localization to mutant p53 but had no apparent effect on p53 conformation. Lysine 15-18 P53 Homo sapiens 106-109 17371868-6 2007 Interestingly, Lys to Arg mutations that inhibited ubiquitination restored nuclear localization to mutant p53 but had no apparent effect on p53 conformation. Arginine 22-25 P53 Homo sapiens 106-109 17353187-6 2007 HSCO specifically associates with histone deacetylase 1 (HDAC1) independently of Mdm2 and facilitates deacetylation of p53 at Lys-373/382 by HDAC1. Lysine 126-129 P53 Homo sapiens 119-122 17523842-4 2007 Among the signaling molecules examined, levels of p53 phosphorylated at Ser-392 and p38 were higher in UVB-irradiated cells than in UVC-irradiated cells. Serine 72-75 P53 Homo sapiens 50-53 17523842-6 2007 Furthermore, an inhibitor of p38 also blocked the phosphorylation of p53 at Ser-392.

Cisplatin 42-51 P53 Homo sapiens 10-13 17344208-11 2007 This is significant because superoxide production underlies the role of human PRODH in p53-mediated apoptosis, implying commonalities between eukaryotic and bacterial monofunctional PRODHs. Superoxides 28-38 P53 Homo sapiens 87-90 17686239-12 2007 CONCLUSION: Residual tumor, p53, and Pgp expression are predictive factors for the response to platinum/paclitaxel first-line adjuvant chemotherapy in advanced ovarian cancer. Paclitaxel 104-114 P53 Homo sapiens 28-31 17072341-5 2007 These experiments identify p53 as the main pathway producing a large-scale transcriptional response after cisplatin treatment in these cells containing wild-type p53. Cisplatin 106-115 P53 Homo sapiens 27-30 17072341-5 2007 These experiments identify p53 as the main pathway producing a large-scale transcriptional response after cisplatin treatment in these cells containing wild-type p53. Cisplatin 106-115 P53 Homo sapiens 162-165 17072341-6 2007 Consistent with a role for the p53 response in cisplatin sensitivity, knockdown of the p53 protein with small interfering RNA led to a twofold decrease in cell survival in the resistant cells. Cisplatin 47-56 P53 Homo sapiens 31-34 17072341-6 2007 Consistent with a role for the p53 response in cisplatin sensitivity, knockdown of the p53 protein with small interfering RNA led to a twofold decrease in cell survival in the resistant cells.

Copper 0-6 P53 Homo sapiens 66-69 17672938-1 2007 BACKGROUND & OBJECTIVE: p53 gene is the main regulator of 14-3-3sigma. Adenosine Monophosphate 12-15 P53 Homo sapiens 28-31 17595754-8 2007 There was a association between the absence of p53 and high serum progesterone (p = 0.046). Progesterone 66-78 P53 Homo sapiens 47-50 17595776-6 2007 Those who had Arg/Arg at p53 codon 72 showed a 2.68-fold (95% confidence interval = 1.19-6.01) increased risk of oral cancer compared to those with Pro/Pro. Arginine 14-17 P53 Homo sapiens 25-28 17595776-6 2007 Those who had Arg/Arg at p53 codon 72 showed a 2.68-fold (95% confidence interval = 1.19-6.01) increased risk of oral cancer compared to those with Pro/Pro. Arginine 18-21 P53 Homo sapiens 25-28 17595776-9 2007 CONCLUSION: Our findings suggest that the homozygous Arg allele of the p53 codon 72 may be associated with the development of oral cancer and be a useful marker for primary prevention and anticancer intervention. Arginine 53-56 P53 Homo sapiens 71-74 17380529-3 2007 METHODS: P53 expression was determined by immunohistochemistry in paraffin-embedded tissue specimens from 107 consecutive patients (107 primary squamous cell carcinomas of the supraglottic larynx and 46 matched lymph node metastases). Paraffin 66-74 P53 Homo sapiens 9-12 17119966-10 2007 NF-kappaB transfected MCF-7 and p53 knockout HCT116 cells were resistant to 5-FU (4.4- and 2.4-fold, respectively) but not to TDX. Fluorouracil 76-80 P53 Homo sapiens 32-35 17119966-13 2007 Loss of p53 function and NF-kappaB over-expression may be involved in TS-independent 5-FU chemoresistance in some cancer cell lines. Fluorouracil 85-89 P53 Homo sapiens 8-11 17390010-8 2007 Interestingly, this mutant-p53 prevented Saos-2 cells from undergoing apoptosis after treatment with a DNA damaging agent, adriamycin. Doxorubicin 123-133 P53 Homo sapiens 27-30 17631738-2 2007 The wild type p53 protein presents a common polymorphism at position 72 resulting in either a proline or an arginine residue at this position, leading to differences between the two variants in the induction of apoptosis. Arginine 108-116 P53 Homo sapiens 14-17 17631738-7 2007 All of the RA patients and controls were genotyped by the polymerase chain reaction and allele-specific oligonucleotide techniques for p53 gene polymorphism Arg/Pro at codon 72. Arginine 157-160 P53 Homo sapiens 135-138 17289842-8 2007 OxLDL activated p53 through production of mitochondria-derived reactive oxygen species. Reactive Oxygen Species 63-86 P53 Homo sapiens 16-19 17289842-9 2007 In EDCs treated with a recombinant adenovirus expressing superoxide dismutase or N-acetyl-cysteine (but not catalase), the p53-Bax pathway activated by oxLDL was blocked, and apoptosis was prevented. Acetylcysteine 81-98 P53 Homo sapiens 123-126 17289842-11 2007 These findings suggest that exposure of EDCs and endothelial cells to either experimentally prepared or naturally occurring modified LDL results in an increased transfer of mitochondria-derived superoxide anion to p53, which stimulates a conformational change in Bax favoring its translocation to the mitochondria with resultant apoptosis of these cells. Superoxides 194-210 P53 Homo sapiens 214-217 17230520-8 2007 In LNCaP cells, we established superoxide as a primary mediator for selenite-induced DNA SSBs, p53 activation and caspase-mediated apoptosis. Superoxides 31-41 P53 Homo sapiens 95-98 17230520-9 2007 Furthermore a p53-dominant negative mutant attenuated selenite-induced ROS, leading to a proportionate protection against apoptosis. Reactive Oxygen Species 71-74 P53 Homo sapiens 14-17 17230520-10 2007 The results support the p53-mitochondria axis in a feedback loop for sustaining superoxide production to lead to efficient caspase-mediated apoptosis by selenite. Superoxides 80-90 P53 Homo sapiens 24-27 17331670-7 2007 The p53 72 Arg allele showed a borderline association (p = 0.07). Arginine 11-14 P53 Homo sapiens 4-7 17208332-1 2007 The TP53 gene has a polymorphism in exon 4 at codon 72 that presents the arginine or proline genotype. Arginine 73-81 P53 Homo sapiens 4-8 17446929-2 2007 Here we demonstrated that the p53 family member p63 controls a pathway for p73-dependent cisplatin sensitivity specific to these "triple-negative" tumors. Cisplatin 89-98 P53 Homo sapiens 30-33 17599946-1 2007 A TP53 gene polymorphism, resulting in an arginine (R) to proline (P) at codon 72 (TP53 R72P), has been associated with the susceptibility to various cancers. Arginine 42-50 P53 Homo sapiens 2-6 17599946-1 2007 A TP53 gene polymorphism, resulting in an arginine (R) to proline (P) at codon 72 (TP53 R72P), has been associated with the susceptibility to various cancers. Arginine 42-50 P53 Homo sapiens 83-87 17599946-6 2007 We conclude that the TP53 R72P polymorphism may contribute to the etiology of colorectal cancer in the Chinese population, particularly among alcohol consumers. Alcohols 142-149 P53 Homo sapiens 21-25 17130844-5 2007 Consistently, such a protective effect can be at least partially due to the impairment of cisplatin-induced p53 activation, occurring early in committed, preapoptotic cells. Cisplatin 90-99 P53 Homo sapiens 108-111 17339337-1 2007 Genetic and biochemical studies have shown that Ser(20) phosphorylation in the transactivation domain of p53 mediates p300-catalyzed DNA-dependent p53 acetylation and B-cell tumor suppression. Serine 48-51 P53 Homo sapiens 105-108 17339337-1 2007 Genetic and biochemical studies have shown that Ser(20) phosphorylation in the transactivation domain of p53 mediates p300-catalyzed DNA-dependent p53 acetylation and B-cell tumor suppression. Serine 48-51 P53 Homo sapiens 147-150 17339337-4 2007 Phosphorylation of a p53 transactivation domain fragment at Ser(20) by these enzymes in vitro can be mediated in trans by a docking site peptide derived from the BOX-V domain of p53, which also harbors the ubiquitin signal for MDM2. Serine 60-63 P53 Homo sapiens 21-24 17339337-4 2007 Phosphorylation of a p53 transactivation domain fragment at Ser(20) by these enzymes in vitro can be mediated in trans by a docking site peptide derived from the BOX-V domain of p53, which also harbors the ubiquitin signal for MDM2. Serine 60-63 P53 Homo sapiens 178-181 17513613-6 2007 Because we previously showed that reintroduction of wild-type p53 (wtp53) into STS cells harboring a p53 mutation led to increased doxorubicin chemosensitivity, we hypothesized that p53 participates in regulating Rad51 expression in STS. Doxorubicin 131-142 P53 Homo sapiens 62-65 17513613-6 2007 Because we previously showed that reintroduction of wild-type p53 (wtp53) into STS cells harboring a p53 mutation led to increased doxorubicin chemosensitivity, we hypothesized that p53 participates in regulating Rad51 expression in STS. Doxorubicin 131-142 P53 Homo sapiens 69-72 17513613-6 2007 Because we previously showed that reintroduction of wild-type p53 (wtp53) into STS cells harboring a p53 mutation led to increased doxorubicin chemosensitivity, we hypothesized that p53 participates in regulating Rad51 expression in STS. Doxorubicin 131-142 P53 Homo sapiens 69-72 17474797-3 2007 The two non-synonymous single-nucleotide polymorphisms (SNPs) TP53 codon 72 Arg/Pro G>C and CDKN1A codon 31 Ser/Arg C>A were genotyped in 92 normal fibroblast cell strains of different radiosensitivity. Arginine 76-79 P53 Homo sapiens 62-66 17371049-9 2007 After incorporating 6-19F-Trp, it is found that, in the triple mutant, Trp53 shows conformational heterogeneity at low temperature while Trp44, which is close to the P27A mutation, does not. Tryptophan 26-29 P53 Homo sapiens 71-76 17387280-3 2007 This mixed experimental-simulation approach enabled us to decode the dynamics of the cytostatic and cytotoxic responses to cisplatin and doxorubicin treatments in a p53--proficient colon carcinoma cell line (HCT-116) and in its p53-deficient counterpart. Cisplatin 123-132 P53 Homo sapiens 165-168 17387280-3 2007 This mixed experimental-simulation approach enabled us to decode the dynamics of the cytostatic and cytotoxic responses to cisplatin and doxorubicin treatments in a p53--proficient colon carcinoma cell line (HCT-116) and in its p53-deficient counterpart.

Doxorubicin 137-148 P53 Homo sapiens 165-168 17387280-3 2007 This mixed experimental-simulation approach enabled us to decode the dynamics of the cytostatic and cytotoxic responses to cisplatin and doxorubicin treatments in a p53--proficient colon carcinoma cell line (HCT-116) and in its p53-deficient counterpart. Doxorubicin 137-148 P53 Homo sapiens 228-231 17307730-7 2007 Nampt overexpression also reduced the fraction of p53 that was acetylated on lysine 382, a target of SIRT1, suppressed an age-related increase in p53 expression, and increased the rate of p53 degradation. Lysine 77-83 P53 Homo sapiens 50-53 17307730-7 2007 Nampt overexpression also reduced the fraction of p53 that was acetylated on lysine 382, a target of SIRT1, suppressed an age-related increase in p53 expression, and increased the rate of p53 degradation. Lysine 77-83 P53 Homo sapiens 146-149 17307730-7 2007 Nampt overexpression also reduced the fraction of p53 that was acetylated on lysine 382, a target of SIRT1, suppressed an age-related increase in p53 expression, and increased the rate of p53 degradation. Lysine 77-83 P53 Homo sapiens 146-149 17406354-1 2007 The preferential retention of the arginine allele at the p53 codon 72 locus is commonly observed in tumours from arginine/proline heterozygotes. Arginine 34-42 P53 Homo sapiens 57-60 17406354-1 2007 The preferential retention of the arginine allele at the p53 codon 72 locus is commonly observed in tumours from arginine/proline heterozygotes. Arginine 113-121 P53 Homo sapiens 57-60 17406354-3 2007 Here, we show that the transient transfection of the proline allele in p53 null cancer cells exposed to low oxygen tension or to the hypoxia-mimetic drug Desferoxamine induces a higher amount of cell death than the arginine allele. Oxygen 108-114 P53 Homo sapiens 71-74 17406354-3 2007 Here, we show that the transient transfection of the proline allele in p53 null cancer cells exposed to low oxygen tension or to the hypoxia-mimetic drug Desferoxamine induces a higher amount of cell death than the arginine allele. Arginine 215-223 P53 Homo sapiens 71-74 17406354-6 2007 These data indicate that the p53 codon 72 proline allele is less permissive for the growth of cancer cells in a hypoxic environment, and suggest that the preferential retention of the arginine allele in the tumour tissues of arginine/proline heterozygous patients may depend upon its lowered capacity to induce cell death in a hypoxic tumour environment. Arginine 184-192 P53 Homo sapiens 29-32 17406354-6 2007 These data indicate that the p53 codon 72 proline allele is less permissive for the growth of cancer cells in a hypoxic environment, and suggest that the preferential retention of the arginine allele in the tumour tissues of arginine/proline heterozygous patients may depend upon its lowered capacity to induce cell death in a hypoxic tumour environment. Arginine 225-233 P53 Homo sapiens 29-32 17195093-3 2007 Hypoxia-induced cell death was not associated with the activation of p53 while cisplatin-induced apoptosis is p53 dependent. Cisplatin 79-88 P53 Homo sapiens 110-113 17397945-6 2007 p53 siRNA prevented cisplatin-mediated up-regulation of FLJ11259 in NT2/D1 cells. Cisplatin 20-29 P53 Homo sapiens 0-3 17240359-6 2007 We found that curcumin enhanced the expression of tumor cyclin-dependent kinase (CDK) inhibitors p21 and p27 as well as tumor suppressor protein p53 but suppressed the expression of retinoblastoma protein. Curcumin 14-22 P53 Homo sapiens 145-148 17397945-9 2007 In addition, chromatin immunoprecipitation assays indicate that p53 binds directly to this element in vivo and that binding is enhanced following cisplatin treatment. Cisplatin 146-155 P53 Homo sapiens 64-67 17409429-3 2007 We found that PD98059, which itself has minimal apoptogenic activity, acts synergistically with Nutlin-3a to induce apoptosis in wild-type p53 AML cell lines OCI-AML-3 and MOLM-13. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 14-21 P53 Homo sapiens 139-142 17409429-4 2007 Interestingly, PD98059 enhanced nuclear proapototic function of p53 in these cells. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 15-22 P53 Homo sapiens 64-67 17409429-5 2007 In accordance with the activation of transcription-dependent apoptosis, PD98059 treatment promoted the translocation of p53 from the cytoplasm to the nucleus in OCI-AML-3 cells, in which p53 primarily initiates transcription-independent apoptosis when cells are treated with Nutlin-3a alone. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 72-79 P53 Homo sapiens 120-123 17409429-5 2007 In accordance with the activation of transcription-dependent apoptosis, PD98059 treatment promoted the translocation of p53 from the cytoplasm to the nucleus in OCI-AML-3 cells, in which p53 primarily initiates transcription-independent apoptosis when cells are treated with Nutlin-3a alone. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 72-79 P53 Homo sapiens 187-190 17409429-7 2007 PD98059 prevented p53-mediated induction of p21 at the transcriptional level. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 0-7 P53 Homo sapiens 18-21 17409429-8 2007 The repressed expression of antiapototic p21 also seemed to contribute to synergism between PD98059 and Nutlin-3a because (a) the synergistic apoptogenic effect was preserved in G(1) cells, (b) p53-mediated induction of p21 was preferentially seen in G(1) cells, (c) PD98059 strongly antagonized p21 induction by Nutlin-3a, and (d) cells with high p21 levels were resistant to apoptosis. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 92-99 P53 Homo sapiens 194-197 17454128-2 2007 We demonstrated that UVA-irradiated NADH induced damage to (32)P-labeled DNA fragments obtained from the p53 gene in the presence of Cu(II). NAD 36-40 P53 Homo sapiens 105-108 17332930-11 2007 Overexpression of constitutively active AKT inhibited curcumin-induced p53 translocation to mitochondria, and Smac release to cytoplasm, whereas inhibition of AKT by dominant negative AKT enhanced curcumin-induced p53 translocation to mitochondria and Smac release. Curcumin 54-62 P53 Homo sapiens 71-74 17332930-0 2007 Involvement of Bcl-2 family members, phosphatidylinositol 3"-kinase/AKT and mitochondrial p53 in curcumin (diferulolylmethane)-induced apoptosis in prostate cancer. Curcumin 97-105 P53 Homo sapiens 90-93 17332930-11 2007 Overexpression of constitutively active AKT inhibited curcumin-induced p53 translocation to mitochondria, and Smac release to cytoplasm, whereas inhibition of AKT by dominant negative AKT enhanced curcumin-induced p53 translocation to mitochondria and Smac release. Curcumin 54-62 P53 Homo sapiens 214-217 17332930-4 2007 Curcumin downregulated the expression of Bcl-2, and Bcl-XL and upregulated the expression of p53, Bax, Bak, PUMA, Noxa, and Bim. Curcumin 0-8 P53 Homo sapiens 93-96 17575952-0 2007 Time and dose-dependent activation of p53 serine 15 phosphorylation among cell lines with different radiation sensitivity. Serine 42-48 P53 Homo sapiens 38-41 17575952-2 2007 The serine 15 (Ser15) on p53 is crucial for p53 stabilization and a requirement for transient and permanent cell cycle arrest. Serine 4-10 P53 Homo sapiens 25-28 17575952-2 2007 The serine 15 (Ser15) on p53 is crucial for p53 stabilization and a requirement for transient and permanent cell cycle arrest. Serine 4-10 P53 Homo sapiens 44-47 17332930-5 2007 Curcumin upregulated the expression of p53 as well as its phosphorylation at serine 15, and acetylation in a concentration-dependent manner. Curcumin 0-8 P53 Homo sapiens 39-42 17332930-12 2007 Our study establishes a role for AKT in modulating the direct action of p53 on the caspase-dependent mitochondrial death pathway and suggests that these important biological molecules interact at the level of the mitochondria to influence curcumin sensitivity. Curcumin 239-247 P53 Homo sapiens 72-75 17332930-5 2007 Curcumin upregulated the expression of p53 as well as its phosphorylation at serine 15, and acetylation in a concentration-dependent manner. Serine 77-83 P53 Homo sapiens 39-42 17332930-7 2007 Treatment of LNCaP cells with curcumin resulted in translocation of Bax and p53 to mitochondria, production of reactive oxygen species, drop in mitochondrial membrane potential, release of mitochondrial proteins (cytochrome c, Smac/DIABLO and Omi/HtrA2), activation of caspase-3 and induction of apoptosis. Curcumin 30-38 P53 Homo sapiens 76-79 17575952-3 2007 Here, we sought to determine the relationship between p53 serine 15 phosphorylation (p53-p-Ser15) on cellular sensitivity and if this modification is associated with DNA double-strand break (DSB) repair. Serine 58-64 P53 Homo sapiens 54-57 17575952-3 2007 Here, we sought to determine the relationship between p53 serine 15 phosphorylation (p53-p-Ser15) on cellular sensitivity and if this modification is associated with DNA double-strand break (DSB) repair. Serine 58-64 P53 Homo sapiens 85-88 17332940-8 2007 Following silencing of p53 or p21 we observed extensive apoptosis concomitant with extensive depolarization of mitochondrial membrane and depletion of reduced glutathione. Glutathione 159-170 P53 Homo sapiens 23-26 17406801-0 2007 Radiosensitization dependent on p53 function in bronchial carcinoma cells by the isoflavone genistein and estradiol in vitro. Estradiol 106-115 P53 Homo sapiens 32-35 17063488-3 2007 We report that Carb or 5-FU upregulate Gadd45alpha and p53 in both these cells. Fluorouracil 23-27 P53 Homo sapiens 55-58 17449938-7 2007 In addition, minoxidil plus ATRA elevated phosphorylated Erk, phosphorylated Akt and the ratio of Bcl-2/Bax, but decreased the expressions of P53 and P21 more effectively than by minoxidil alone. Tretinoin 28-32 P53 Homo sapiens 142-145 17449938-8 2007 Our results suggest that minoxidil plus ATRA would additively enhance hair growth by mediating dual functions: 1) the prolongation of cell survival by activating the Erk and Akt signaling pathways, and 2) the prevention of apoptosis of DPCs and epithelial cells by increasing the ratio of Bcl-2/Bax and downregulating the expressions of P53 and P21. Tretinoin 40-44 P53 Homo sapiens 337-340 17461764-9 2007 An extremely low concentration of cisplatin in addition to Ps-S-Oligos further up-regulated p53 activity, provoking massive apoptotic induction. Cisplatin 34-43 P53 Homo sapiens 92-95 17515111-6 2007 We have found that apomorphine hydrochloride promotes degradation of intracellular AM and p53 attenuating oxidative stress-induced apoptosis. Apomorphine 19-44 P53 Homo sapiens 90-93 17406801-10 2007 Incubation of nonfunctional TP53 cells with genistein or estradiol increased radiosensitivity in both tested concentrations. Estradiol 57-66 P53 Homo sapiens 28-32 17406801-13 2007 CONCLUSION: NSCLC cells with nonfunctional TP53 might be sensitized against radiation by genistein or estradiol. Estradiol 102-111 P53 Homo sapiens 43-47 17276397-4 2007 p53 accumulated in response to cisplatin (CDDP) and thereby promoting apoptosis in neuroblastoma SH-SY5Y cells bearing wild-type p53, whereas SK-N-AS cells did not undergo apoptosis. Cisplatin 31-40 P53 Homo sapiens 0-3 17292432-0 2007 Phosphorylation of p53 at serine 15 in A549 pulmonary epithelial cells exposed to vanadate: involvement of ATM pathway. Serine 26-32 P53 Homo sapiens 19-22 17292432-1 2007 When A549 cells were exposed to sodium metavanadate (NaVO(3)), the pentavalent species of vanadium (vanadate), phosphorylation of p53 protein at Ser15 was found in a time (8-48 h)- and dose (10-200 microM)-dependent manner. Vanadium 90-98 P53 Homo sapiens 130-133 17292432-3 2007 Among serines in p53 protein immunoprecipitated from A549 cells treated with 100 microM NaVO(3) for 48 h, only Ser15 was markedly phosphorylated. Serine 6-13 P53 Homo sapiens 17-20 17276397-4 2007 p53 accumulated in response to cisplatin (CDDP) and thereby promoting apoptosis in neuroblastoma SH-SY5Y cells bearing wild-type p53, whereas SK-N-AS cells did not undergo apoptosis. Cisplatin 42-46 P53 Homo sapiens 0-3 17381838-10 2007 CONCLUSION: These observations support a role for p53-mediated transcriptional program in mammalian aging and suggest that mechanisms other than reactive oxygen species are involved in the age-related transcriptional activation of p53 targets. Reactive Oxygen Species 145-168 P53 Homo sapiens 231-234 17242401-0 2007 5-fluorouracil activation of p53 involves an MDM2-ribosomal protein interaction. Fluorouracil 0-14 P53 Homo sapiens 29-32 17242401-2 2007 The anti-tumor activity of 5-FU has been attributed in part to its ability to induce p53-dependent cell growth arrest and apoptosis. Fluorouracil 27-31 P53 Homo sapiens 85-88 17242401-3 2007 However, the molecular mechanisms underlying p53 activation by 5-FU remain largely obscure. Fluorouracil 63-67 P53 Homo sapiens 45-48 17242401-4 2007 Here we report that 5-FU treatment leads to p53 stabilization and activation by blocking MDM2 feedback inhibition through ribosomal proteins. Fluorouracil 20-24 P53 Homo sapiens 44-47 17242401-5 2007 5-FU treatment increased the fraction of ribosome-free L5, L11, and L23 ribosomal proteins and their interaction with MDM2, leading to p53 activation and G1/S arrest. Fluorouracil 0-4 P53 Homo sapiens 135-138 17242401-6 2007 Conversely, individual knockdown of these ribosomal proteins by small interfering RNA prevented the 5-FU-induced p53 activation and reversed the 5-FU-induced G1/S arrest. Fluorouracil 100-104 P53 Homo sapiens 113-116 17242401-7 2007 These results demonstrate that 5-FU treatment triggers a ribosomal stress response so that ribosomal proteins L5, L11, and L23 are released from ribosome to activate p53 by ablating the MDM2-p53 feedback circuit. Fluorouracil 31-35 P53 Homo sapiens 166-169 17242401-7 2007 These results demonstrate that 5-FU treatment triggers a ribosomal stress response so that ribosomal proteins L5, L11, and L23 are released from ribosome to activate p53 by ablating the MDM2-p53 feedback circuit. Fluorouracil 31-35 P53 Homo sapiens 191-194 17293044-4 2007 Treatment of the cells with all trans retinoic acid (RA) generates a neuron-like, morphological change of differentiation, and results in the activation of ERK and Akt pathways, an inhibition of the nuclear translocation of p53 induced by GA, and induces higher resistance to the GA-induced apoptosis. Tretinoin 38-51 P53 Homo sapiens 224-227 17297916-9 2007 We, therefore, generated an artificial p53, containing arginine residues N-terminal to the phospho-acceptor site, creating a better DAPK-1 peptide consensus and demonstrated that the Km for p531-66[ET-->RR] and ATP is elevated. Arginine 55-63 P53 Homo sapiens 39-42 17297916-9 2007 We, therefore, generated an artificial p53, containing arginine residues N-terminal to the phospho-acceptor site, creating a better DAPK-1 peptide consensus and demonstrated that the Km for p531-66[ET-->RR] and ATP is elevated. Adenosine Triphosphate 214-217 P53 Homo sapiens 39-42 17297920-0 2007 Zn(2+)-dependent misfolding of the p53 DNA binding domain. Zinc 0-6 P53 Homo sapiens 35-38 17339891-4 2007 Lovo 175X2 cells (transfected with mt p53) were more resistant to 5-fluorouracil (5-FU; 2-fold), nolatrexed (3-fold), raltitrexed (3-fold) and pemetrexed (10-fold) in comparison with the wt p53 parental cells Lovo 92. Fluorouracil 66-80 P53 Homo sapiens 38-41 17339891-4 2007 Lovo 175X2 cells (transfected with mt p53) were more resistant to 5-fluorouracil (5-FU; 2-fold), nolatrexed (3-fold), raltitrexed (3-fold) and pemetrexed (10-fold) in comparison with the wt p53 parental cells Lovo 92. Fluorouracil 82-86 P53 Homo sapiens 38-41 17332358-1 2007 Phosphorylation of p53 at Ser(46) is important to activate the apoptotic program. Serine 26-29 P53 Homo sapiens 19-22 17457979-3 2007 Cell proliferation was measured by CCK-8 assay, and the expression of two cell cycle regulators, p53 and p21, was determined by SDS-PAGE and Western blotting. Sodium Dodecyl Sulfate 128-131 P53 Homo sapiens 97-100 17216584-5 2007 The ER stress-inducing agent thapsigargin also induced p53-independent Noxa expression. Thapsigargin 29-41 P53 Homo sapiens 55-58 17216584-6 2007 Conversely, Noxa transcription in response to the chemotherapeutic agents cisplatin or temozolomide was inhibited by p53 knockdown. Cisplatin 74-83 P53 Homo sapiens 117-120 17216584-7 2007 Apoptosis in response to cisplatin or temozolomide was also inhibited by abrogation of p53 expression yet apoptosis in response to fenretinide or thapsigargin was unaffected. Cisplatin 25-34 P53 Homo sapiens 87-90 19690636-0 2007 BRCA1 Expression is an Important Biomarker for Chemosensitivity: Suppression of BRCA1 Increases the Apoptosis via Up-regulation of p53 and p21 During Cisplatin Treatment in Ovarian Cancer Cells. Cisplatin 150-159 P53 Homo sapiens 131-134 19690636-5 2007 Reduced expression of BRCA1 by transfection of BRCA1-siRNA resulted in a 5.3-fold increase in sensitivity to cisplatin in p53-wild A2780 cells, but not in p53-mutated A2780/CDDP and p53-deleted SKOV3 cells. Cisplatin 109-118 P53 Homo sapiens 122-125 19690636-9 2007 However, cisplatin treatment under suppression of BRCA1 showed a significantly increased apoptosis along with up-regulation of p53 and p21 in A2780 cells. Cisplatin 9-18 P53 Homo sapiens 127-130 17332326-4 2007 In a human prostate cancer cell lines PC3 (p53(null)), curcumin reduced MDM2 protein and mRNA in a dose- and time-dependent manner, and enhanced the expression of the tumor suppressor p21(Waf1/CIP1). Curcumin 55-63 P53 Homo sapiens 43-46 17332358-2 2007 The protein kinase that phosphorylates p53 Ser(46) in response to DNA double-strand breaks is currently unknown. Serine 43-46 P53 Homo sapiens 39-42 17332358-5 2007 IR-induced HIPK2 up-regulation strictly correlates with p53 Ser(46) phosphorylation. Serine 60-63 P53 Homo sapiens 56-59 17332358-6 2007 Down-regulation of HIPK2 by RNA interference specifically inhibits IR-induced phosphorylation of p53 at Ser(46). Serine 104-107 P53 Homo sapiens 97-100 17332358-11 2007 Taken together, our findings indicate that HIPK2 is the IR-activated p53 Ser(46) kinase and is regulated by ATM. Serine 73-76 P53 Homo sapiens 69-72 17050787-10 2007 However, modulator proteins p53, p21, and p27 were increased by resveratrol only in LNCaP cells. Resveratrol 64-75 P53 Homo sapiens 28-31 17133364-4 2007 We now report that 22 oligonucleotides, 9-20 bases in length, with or without a 5" phosphate group and with varying homology (40-100%) to the 3" overhang, inhibit growth and induce apoptosis of human cell lines derived from breast cancers, pancreatic and ovarian carcinomas, and malignant melanoma, lines that lack p53 and/or p16 and harbor a variety of other abnormalities in key regulatory signaling pathways. Oligonucleotides 22-38 P53 Homo sapiens 315-318 17121856-6 2007 Furthermore, the co-activator complexes initiate the recruitment of the components of the basal transcription apparatus to the basal promoter with markedly different outcomes because only Ac-Lys-373 p53 promotes the assembly of the basal transcriptional apparatus on the p21 promoter. Lysine 191-194 P53 Homo sapiens 199-202 17203463-0 2007 Roscovitine-activated HIP2 kinase induces phosphorylation of wt p53 at Ser-46 in human MCF-7 breast cancer cells. Serine 71-74 P53 Homo sapiens 64-67 17203463-4 2007 The p53 level increased despite upregulation of Hdm-2 protein and was attributable to the site-specific phosphorylation at Ser-46. Serine 123-126 P53 Homo sapiens 4-7 17203463-5 2007 The p53 protein phosphorylated at serine 46 causes the up-regulation of the p53AIP1 protein, a component of mitochondria. Serine 34-40 P53 Homo sapiens 4-7 17203463-8 2007 The overexpression of wild-type but not kinase inactive HIPK2 increased the basal and ROSC-induced level of p53 phosphorylation at Ser-46 and strongly enhanced the rate of apoptosis in cells exposed to ROSC. Serine 131-134 P53 Homo sapiens 108-111 17203463-9 2007 We show that HIPK2 is activated by ROSC and mediates ROSC-induced P-Ser-46-p53, thereby stabilizing wt p53 and increasing the efficacy of drug-induced apoptosis in MCF-7 cells. Serine 68-71 P53 Homo sapiens 75-78 17550137-0 2007 Synergic CSE1L/CAS, TNFR-1, and p53 apoptotic pathways in combined interferon-gamma/adriamycin-induced apoptosis of Hep G2 hepatoma cells. Doxorubicin 84-94 P53 Homo sapiens 32-35 17550137-6 2007 Adriamycin increased p53 and Bax, but not TNFR- 1 and CAS levels. Doxorubicin 0-10 P53 Homo sapiens 21-24 17550137-7 2007 Interferon-y did not increase p53 accumulation; nevertheless it enhanced adriamycin-induced p53 accumulation. Doxorubicin 73-83 P53 Homo sapiens 92-95 17550137-8 2007 Overexpression of IRF-1 augmented the combined interferon-gamma/adriamycin-induced p53 accumulation. Doxorubicin 64-74 P53 Homo sapiens 83-86 17550137-9 2007 Interferon-gamma co-treatment increased the stability of p53 protein induced by adriamycin. Doxorubicin 80-90 P53 Homo sapiens 57-60 17218071-3 2007 DNA binding of benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) was analyzed by synchronous fluorescence spectrophotometry and p53 protein by immunoblotting. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 15-51 P53 Homo sapiens 122-125 16924239-8 2007 This suggests that the presence of functional p53 protein may enhance death induction by rimcazole in part through greater induction of HIF-1alpha. rimcazole 89-98 P53 Homo sapiens 46-49 16924240-4 2007 Expression of ubiquitin derivatives with all lysines mutated except K48 or K63 demonstrated that K48-linked p53-ubiquitin conjugates were specifically induced after DNA damage. Lysine 45-52 P53 Homo sapiens 108-111 16870476-6 2007 RESULTS: Verapamil increased the tail moments induced by doxorubicin in all cell types over-expressing p53 mutant protein. Doxorubicin 57-68 P53 Homo sapiens 103-106 17388661-0 2007 Exquisite sensitivity of TP53 mutant and basal breast cancers to a dose-dense epirubicin-cyclophosphamide regimen. Epirubicin 78-88 P53 Homo sapiens 25-29 17388661-16 2007 CONCLUSIONS: This study demonstrates that, in noninflammatory breast cancers, TP53 status is a key predictive factor for response to this dose-dense epirubicin-cyclophosphamide regimen and further suggests that the basal subtype is exquisitely sensitive to this association. Epirubicin 149-159 P53 Homo sapiens 78-82 17190831-8 2007 Furthermore, expression of p21, which correlates with taxane sensitivity, is regulated by CAV1 phosphorylation in a p53-dependent manner. taxane 54-60 P53 Homo sapiens 116-119 17308111-7 2007 This activation, in combination with BaP-induced phosphorylated p53, promoted mitochondrial superoxide anion production, supporting the existence of a common target for NHE1 and p53. Superoxides 92-108 P53 Homo sapiens 64-67 17147953-9 2007 Moreover, MNNG-induced increase in acetylation of p53, a representative target of sirtuin deacetylase activity, was suppressed by resveratrol. Resveratrol 130-141 P53 Homo sapiens 50-53 17308111-7 2007 This activation, in combination with BaP-induced phosphorylated p53, promoted mitochondrial superoxide anion production, supporting the existence of a common target for NHE1 and p53. Superoxides 92-108 P53 Homo sapiens 178-181 17285121-7 2007 MonoHER suppressed DOX-dependent activation of the mitochondrial apoptotic pathway in normal and A2780 cells as illustrated by p53 accumulation and activation of caspase-9 and -3 cleavage. Doxorubicin 19-22 P53 Homo sapiens 127-130 17317843-0 2007 DNA mismatch repair initiates 6-thioguanine--induced autophagy through p53 activation in human tumor cells. Thioguanine 30-43 P53 Homo sapiens 71-74 17317843-1 2007 PURPOSE: We investigate the roles of DNA mismatch repair (MMR) and p53 in mediating the induction of autophagy in human tumor cells after exposure to 6-thioguanine (6-TG), a chemotherapy drug recognized by MMR. Thioguanine 150-163 P53 Homo sapiens 67-70 17317843-1 2007 PURPOSE: We investigate the roles of DNA mismatch repair (MMR) and p53 in mediating the induction of autophagy in human tumor cells after exposure to 6-thioguanine (6-TG), a chemotherapy drug recognized by MMR. Thioguanine 165-169 P53 Homo sapiens 67-70 17236862-0 2007 Methionine inhibits cellular growth dependent on the p53 status of cells. Methionine 0-10 P53 Homo sapiens 53-56 17236862-4 2007 However, the generalizability of this observation and the precise role of p53 in methionine-induced growth suppression needs to be determined. Methionine 81-91 P53 Homo sapiens 74-77 17236862-8 2007 The effects of methionine on p53 expression were assessed by using reverse transcriptase-polymerase chain reaction (RT-PCR), immunohistochemistry, and Western blot analysis. Methionine 15-25 P53 Homo sapiens 29-32 17236862-9 2007 The role of p53 in L-methionine-mediated growth suppression was evaluated using short-interference RNA for p53 (siRNA-p53), immunoprecipitation, and direct DNA sequencing. Methionine 19-31 P53 Homo sapiens 12-15 17236862-9 2007 The role of p53 in L-methionine-mediated growth suppression was evaluated using short-interference RNA for p53 (siRNA-p53), immunoprecipitation, and direct DNA sequencing. Methionine 19-31 P53 Homo sapiens 107-110 17236862-9 2007 The role of p53 in L-methionine-mediated growth suppression was evaluated using short-interference RNA for p53 (siRNA-p53), immunoprecipitation, and direct DNA sequencing. Methionine 19-31 P53 Homo sapiens 107-110 17236862-11 2007 In association with the inhibition of growth, methionine also inhibited native p53 expression at the mRNA and protein levels, respectively. Methionine 46-56 P53 Homo sapiens 79-82 17236862-12 2007 Furthermore, transfection with siRNA-p53, to knock down p53 expression, increased cell growth and proliferation of the LNCaP cells even when they were exposed to methionine. Methionine 162-172 P53 Homo sapiens 37-40 17236862-15 2007 CONCLUSION: Our results extend a prior observation to other cell lines and demonstrate that high concentrations of methionine suppress the expression of native but not mutated p53. Methionine 115-125 P53 Homo sapiens 176-179 17244262-5 2007 Paclitaxel treatment combined with apoptin expression significantly inhibited the survival of p53-positive human osteosarcoma U2OS and non-small lung carcinoma A549 cells, p53-negative human osteosarcoma Saos-2 cells and p53-mutant human prostate cancer Du145 cells, already at low doses of the chemotherapeutic agent. Paclitaxel 0-10 P53 Homo sapiens 94-97 17244262-5 2007 Paclitaxel treatment combined with apoptin expression significantly inhibited the survival of p53-positive human osteosarcoma U2OS and non-small lung carcinoma A549 cells, p53-negative human osteosarcoma Saos-2 cells and p53-mutant human prostate cancer Du145 cells, already at low doses of the chemotherapeutic agent.

Cisplatin 67-76 P53 Homo sapiens 24-27 17848273-7 2007 Expression of both Bcl-xL and wild-type p53 caused tumor cells to become cisplatin resistant. Cisplatin 73-82 P53 Homo sapiens 40-43 17848273-9 2007 Novel agents that inhibit Bcl-xL or activate p53 function may target cisplatin-resistant HNSCC. Cisplatin 69-78 P53 Homo sapiens 45-48 17848273-10 2007 CONCLUSION: Cisplatin resistance in HNSCC is mediated, at least in part, by high Bcl-xL and functional p53. Cisplatin 12-21 P53 Homo sapiens 103-106 17237273-7 2007 Western blot analyses showed that SSAT protein expression was dramatically enhanced when DENSpm was combined with oxaliplatin or 5-FU in HCT116 p53(+/+) cells.

Resveratrol 62-66 P53 Homo sapiens 138-141 17077087-8 2006 Considering that p53-induced apoptosis requires an accumulation of reactive oxygen species, this negative control on the Nrf2 transactivation appears to be aimed to prevent the generation of a strong anti-oxidant intracellular environment that could hinder the induction of apoptosis.

Lysine 0-8 P53 Homo sapiens 22-25 17088865-7 2006 Lovastatin attenuated the doxorubicin-induced increase in p53 as well as activation of checkpoint kinase (Chk-1) and stress-activated protein kinase/c-Jun-N-terminal kinase (SAPK/JNK). Doxorubicin 26-37 P53 Homo sapiens 58-61 16895524-5 2006 This decrease was also observed when HepG2 cells were exposed to UV irradiation or doxorubicin, both of which increased endogenous p53 protein levels. Doxorubicin 83-94 P53 Homo sapiens 131-134 16895524-7 2006 Chromatin immunoprecipitation also showed that endogenous p53 bound the HNF4alpha P1 promoter in vivo after doxorubicin treatment.

Bile Acids and Salts 96-105 P53 Homo sapiens 213-216 16971507-6 2006 Conversely, p53 phosphorylation on Ser-15 did not play any role in apoptosis. Serine 35-38 P53 Homo sapiens 12-15 16767497-10 2006 Folate contribution of intestinal bacteria was found to influence p53 protein levels. Folic Acid 0-6 P53 Homo sapiens 66-69 16751801-5 2006 Expression of green fluorescent protein (GFP)-P1 in different mammalian cell lines activates p53 phosphorylation on serine 15, induces an upregulation of p21 and the release of the Cyt-C and apoptosis-inducing factor proapoptotic proteins triggering caspase-dependent and caspase-independent apoptosis. Serine 116-122 P53 Homo sapiens 93-96 17172431-9 2006 Reexpression of wild-type p53 in PC3 cells resulted in increases in superoxide production, apoptosis, and caspase-9 activity and a decrease in mitochondrial membrane potential following cotreatment with SeMet and METase.

Reactive Oxygen Species 182-205 P53 Homo sapiens 27-30 16872707-2 2006 It plays a crucial role in p53-dependent cellular response to DNA damage and oxidative stress by providing deoxyribonucleotides (dNTPs) to the DNA repair machinery and by scavenging reactive oxygen species (ROS). Reactive Oxygen Species 207-210 P53 Homo sapiens 27-30 17110336-3 2006 E4F1 stimulates oligo-ubiquitylation in the hinge region of p53 on lysine residues distinct from those targeted by Hdm2 and previously described to be acetylated by the acetyltransferase PCAF.

Lysine 98-101 P53 Homo sapiens 110-113 17108971-4 2006 This methylation site, in contrast to the known site Lys 372, is repressing to p53-mediated transcriptional regulation. Lysine 53-56 P53 Homo sapiens 79-82 17108971-8 2006 In addition, we show that the inhibitory effect of Lys 372 methylation on Lys 370 methylation is caused, in part, by blocking the interaction between p53 and Smyd2. Lysine 51-54 P53 Homo sapiens 150-153 17108971-8 2006 In addition, we show that the inhibitory effect of Lys 372 methylation on Lys 370 methylation is caused, in part, by blocking the interaction between p53 and Smyd2. Lysine 74-77 P53 Homo sapiens 150-153 17108971-9 2006 Thus, similar to histones, p53 is subject to both activating and repressing lysine methylation.

Tetradecanoylphorbol Acetate 170-173 P53 Homo sapiens 44-47 17108111-4 2006 We show that high doses of TPA induce ATF3 in a WT p53-independent manner correlating with PKCs depletion and cell death. Tetradecanoylphorbol Acetate 27-30 P53 Homo sapiens 51-54 17108111-5 2006 We show that cells harboring mutant p53 have attenuated ATF3 induction and are less sensitive to TPA-induced death compared with their p53-null counterparts.

Doxorubicin 23-34 P53 Homo sapiens 45-48 16826403-10 2006 CONCLUSION: The AN-7 combined with doxorubicin overcame drug resistance; at least in part by the intracellularly releasable formaldehyde that augmented formation of doxorubicin-DNA adducts and butyric acid that induced histone and p53 acetylation. Doxorubicin 35-46 P53 Homo sapiens 231-234 16964247-2 2006 Here, we show that Ser 149 of p53 is O-GlcNAcylated and that this modification is associated with decreased phosphorylation of p53 at Thr 155, which is a site that is targeted by the COP9 signalosome, resulting in decreased p53 ubiquitination.

Threonine 134-137 P53 Homo sapiens 127-130 16964247-2 2006 Here, we show that Ser 149 of p53 is O-GlcNAcylated and that this modification is associated with decreased phosphorylation of p53 at Thr 155, which is a site that is targeted by the COP9 signalosome, resulting in decreased p53 ubiquitination. Threonine 134-137 P53 Homo sapiens 127-130 16964247-3 2006 Accordingly, O-GlcNAcylation at Ser 149 stabilizes p53 by blocking ubiquitin-dependent proteolysis. Serine 32-35 P53 Homo sapiens 51-54 16964247-4 2006 Our results indicate that the dynamic interplay between O-GlcNAc and O-phosphate modifications coordinately regulate p53 stability and activity.

Superoxides 58-60 P53 Homo sapiens 267-270 16652156-11 2006 As suppression of caspase-2 expression in 5-FU-treated cells also affects the level of the p53 protein, possibilities of a reciprocal interaction between these proteins are discussed. Fluorouracil 42-46 P53 Homo sapiens 91-94 20641411-8 2004 Several research studies have reported that resveratrol has the ability to induce p53-dependent apoptosis in several cancer cell lines, and that the signal transduction pathways implicated in resveratrol action includes those of extracellular-regulated kinases 1 and 2 (ERK1/2), p38 kinase, and Jun N-terminal kinase (JNK) (6, 7).

Arginine 21-24 P53 Homo sapiens 4-7 17094395-1 2006 BACKGROUND: The oncoprotein E6 binds to and degrades the p53 tumor suppressor protein, with different efficacy depending on the p53 codon 72 (arg/pro) polymorphism. Arginine 142-145 P53 Homo sapiens 57-60 16325375-3 2006 Here, we report that overexpression of CKIP-1 in SK-BR-3 breast cancer cells prevents p53 degradation induced by cycloheximide treatment through increase of p53 N-terminal Ser-15 phosphorylation level. Serine 172-175 P53 Homo sapiens 157-160 16989090-6 2006 The specificity of this p53 DNA binding SPA was confirmed using competition by oligonucleotides either from the same gene or from mutated versions of this sequence. Oligonucleotides 79-95 P53 Homo sapiens 24-27 16966622-7 2006 Phosphorylation of p53-serine-15, a marker for activation of p53 via genotoxic mechanisms, was absent. Serine 23-29 P53 Homo sapiens 19-22 16951143-6 2006 In this study, we used chromatin immunoprecipitation to determine that p53 preferentially occupied the promoters of growth arrest genes p21 and GADD45 in senescent normal human diploid fibroblasts but not the promoters of other target genes that recruited p53 following doxorubicin-induced DNA damage, such as apoptosis regulators TNFRSF10b, TNFRSF6, and PUMA. Doxorubicin 270-281 P53 Homo sapiens 71-74 16534616-5 2006 RESULTS: The apoptotic index, the extent of DNA damage and the representation of p53 were much lower in the OSCORT cell cultures if the cells were exposed to ECM after treatment with doxorubicin. Doxorubicin 183-194 P53 Homo sapiens 81-84 16931914-4 2006 In this study we have uncovered a novel positive feedback that involves the transcriptional activation of the anti-apoptotic molecule deltaNp63 by the anti-apoptotic molecules deltaNp73 and mutant p53, and that is put into motion upon treatment with a subset of DNA damaging agents such as Doxorubicin and 5-FU. Doxorubicin 290-301 P53 Homo sapiens 197-200 16931914-4 2006 In this study we have uncovered a novel positive feedback that involves the transcriptional activation of the anti-apoptotic molecule deltaNp63 by the anti-apoptotic molecules deltaNp73 and mutant p53, and that is put into motion upon treatment with a subset of DNA damaging agents such as Doxorubicin and 5-FU. Fluorouracil 306-310 P53 Homo sapiens 197-200 16931914-5 2006 DeltaNp73 and mutant p53 associate with the deltaNp63 promoter inducing its transcription and this is enhanced by doxorubicin treatment. Doxorubicin 114-125 P53 Homo sapiens 21-24 16951143-7 2006 This differential recruitment of p53 in senescent versus doxorubicin-treated fibroblasts was accompanied by differences in post-translational modification of p53. Doxorubicin 57-68 P53 Homo sapiens 33-36 16951143-7 2006 This differential recruitment of p53 in senescent versus doxorubicin-treated fibroblasts was accompanied by differences in post-translational modification of p53.

Serine 27-33 P53 Homo sapiens 20-23 16741955-5 2006 We demonstrate that cdk9 phosphorylates p53 on serine 392 through their direct physical interaction. Serine 47-53 P53 Homo sapiens 40-43 16741955-8 2006 Interestingly, cdk9 phosphorylates serine 392 of p53, which could be also phosphorylated by casein kinase II. Serine 35-41 P53 Homo sapiens 49-52 16865258-7 2006 Interestingly, the doxorubicin- and radiation-induced S-/G2-phase arrests were suppressed by p53 in wt conformation. Doxorubicin 19-30 P53 Homo sapiens 93-96 16954562-11 2006 CONCLUSION: These data suggest that abrogation of p53 in breast cancer is associated with specific changes in glucose metabolism detected by PET. Glucose 110-117 P53 Homo sapiens 50-53 16797759-3 2006 By Western blot, the expression of 14-3-3sigma, p53 and p21 was coordinately upregulated in astrocytes following exposure to hydrogen peroxide, 4-hydroxy-2-nonenal (4-HNE) or etoposide, a topoisomerase II inhibitor.

Doxorubicin 33-44 P53 Homo sapiens 106-109 16925398-1 2006 The most potent inhibitor of the p53-MDM2 interaction reported to date is an 8-mer p53 peptide analogue (Novartis peptide), which contains 6-chlorotryptophane (Cl-Trp) and phosphonomethylphenylalanine (Pmp) as key residues for the enhanced activity. phosphonomethylphenylalanine 172-200 P53 Homo sapiens 33-36 16925398-1 2006 The most potent inhibitor of the p53-MDM2 interaction reported to date is an 8-mer p53 peptide analogue (Novartis peptide), which contains 6-chlorotryptophane (Cl-Trp) and phosphonomethylphenylalanine (Pmp) as key residues for the enhanced activity. phosphonomethylphenylalanine 172-200 P53 Homo sapiens 83-86 16814250-3 2006 In the present study, we have found that p53 family member p73 as well as 14-3-3sigma is down-regulated in response to adriamycin (ADR) in ADR-resistant human breast cancer-derived MBA-MD-436 cells which carry p53 mutation. Doxorubicin 119-129 P53 Homo sapiens 41-44 16568081-5 2006 ATRA-mediated apoptosis in CHP134 and NB-39-nu cells was associated with a significant activation of caspase-9 and caspase-3 as well as cytoplasmic release of cytochrome c from mitochondria in a p53-independent manner. Tretinoin 0-4 P53 Homo sapiens 195-198 16931761-4 2006 Ionizing radiation triggered an ATM-dependent movement of COP1 from the nucleus to the cytoplasm, and ATM-dependent phosphorylation of COP1 on Ser(387) was both necessary and sufficient to disrupt the COP1-p53 complex and subsequently to abrogate the ubiquitination and degradation of p53. Serine 143-146 P53 Homo sapiens 206-209 16931761-4 2006 Ionizing radiation triggered an ATM-dependent movement of COP1 from the nucleus to the cytoplasm, and ATM-dependent phosphorylation of COP1 on Ser(387) was both necessary and sufficient to disrupt the COP1-p53 complex and subsequently to abrogate the ubiquitination and degradation of p53. Serine 143-146 P53 Homo sapiens 285-288 16931761-5 2006 Furthermore, phosphorylation of COP1 on Ser(387) was required to permit p53 to become stabilized and to exert its tumor suppressor properties in response to DNA damage. Serine 40-43 P53 Homo sapiens 72-75 16815295-0 2006 p73 and MDM2 confer the resistance of epidermoid carcinoma to cisplatin by blocking p53. Cisplatin 62-71 P53 Homo sapiens 84-87 16814250-3 2006 In the present study, we have found that p53 family member p73 as well as 14-3-3sigma is down-regulated in response to adriamycin (ADR) in ADR-resistant human breast cancer-derived MBA-MD-436 cells which carry p53 mutation. Doxorubicin 119-129 P53 Homo sapiens 210-213 16815295-4 2006 p73 and MDM2 were kept at low levels in the cisplatin-sensitive KB-3-1 cells, whereas p53 was induced to be phosphorylated at Ser-15 in response to cisplatin. Serine 126-129 P53 Homo sapiens 86-89 16815295-4 2006 p73 and MDM2 were kept at low levels in the cisplatin-sensitive KB-3-1 cells, whereas p53 was induced to be phosphorylated at Ser-15 in response to cisplatin. Cisplatin 148-157 P53 Homo sapiens 86-89 16935784-3 2006 Unquestionable biological data must be taken into account to raise relevant questions, such as the role of topoisomerase II in the response to anthracyclines or the role of p53 in the response to taxanes. Taxoids 196-203 P53 Homo sapiens 173-176 16815295-5 2006 In contrast, p73 and MDM2 were expressed at higher levels, and cisplatin-mediated p53 phosphorylation was undetectable in the cisplatin-resistant KCP-4 cells. Cisplatin 63-72 P53 Homo sapiens 82-85 16815295-7 2006 Collectively, our results suggest that a loss of the cisplatin sensitivity is at least in part due to a lack of cisplatin-induced p53 phosphorylation, and p73 might cooperate with MDM2 to be involved in this process. Cisplatin 112-121 P53 Homo sapiens 130-133 16740634-10 2006 Using ChIP assays and immunoprecipitation, we further demonstrated that p53 interacts with Sp1 to suppress both the constitutive and 12-O-tetradecanoylphorbol-13-acetate-stimulated expression of the MnSOD gene. Tetradecanoylphorbol Acetate 133-169 P53 Homo sapiens 72-75 16965670-1 2006 BACKGROUND & OBJECTIVE: It is important to overcome gene therapy resistance caused by wt-p53 in non-small cell lung cancer (NSCLC) . Adenosine Monophosphate 12-15 P53 Homo sapiens 93-96 16945015-3 2006 Thus, nocodazole-treated cells were fluorescently labeled for different cell cycle-associated properties, including DNA content, retinoblastoma (Rb) and histone H3 phosphorylation, p53 and p21(WAF1) expression, nuclear and cell sizes, and cell morphology, and automatically imaged, analyzed, and correlated using HCA.

Serine 55-58 P53 Homo sapiens 94-98 16872365-5 2006 Because the tumour suppressor p53 (tumour protein p53) is known to induce transcription of genes associated with cell response to oxidative stress, we have compared the intensity of constitutive H2AX phosphorylation, and the effect of N-acetyl-L-cysteine on it, in cells with different tumour protein p53 status. Acetylcysteine 235-254 P53 Homo sapiens 30-33 16790523-3 2006 This receptor is linked to induction by resveratrol of extracellular-regulated kinases 1 and 2 (ERK1/2)- and serine-15-p53-dependent phosphorylation leading to apoptosis. Serine 109-115 P53 Homo sapiens 119-122 16835507-3 2006 We evaluated the linkage of the polymorphic variants (Arg/Pro) on TP53 codon 72 with nasopharyngeal cancer development in a case-control study with 392 individuals from a northern Portuguese population, including 107 patients with nasopharyngeal carcinoma and 285 healthy controls.

Resveratrol 140-151 P53 Homo sapiens 167-170 16790523-9 2006 In conclusion, binding of resveratrol to integrin alphaVbeta3, principally to the beta3 monomer, is essential for transduction of the stilbene signal into p53-dependent apoptosis of breast cancer cells. Resveratrol 26-37 P53 Homo sapiens 155-158 16928824-6 2006 The interaction of COX-2, p53, and p300, as well as resveratrol-induced apoptosis, was inhibited by a MAPK activation inhibitor, PD98059. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 129-136 P53 Homo sapiens 26-29 17133770-3 2006 Environmentally induced alterations in p53 protein have been reported to contribute to pathogenesis of leukemia in soft-shell clam Mya arenaria inhabiting polluted water, suggesting that p53 proteins can also be used as pollution markers. Water 164-169 P53 Homo sapiens 39-42 16788846-6 2006 CONCLUSIONS: We were unable to demonstrate any association between the GST genotypes studied and the risk of ovarian cancer but the inheritance of a heterozygous Arg/Pro genotype of p53 increased the risk of ovarian cancer more than 2.5 times (OR = 2.571; 95% CI = 1.453-4.550).

Disulfides 171-180 P53 Homo sapiens 62-65 16681385-6 2006 Treatment of p53-null Saos-2 cells with reversibly cationized p53 revealed that all events examined as indications of the activation of p53 in cells, such as reduction of disulfide bonds followed by tetramer formation, localization into the nucleus, induction of p53 target genes, and induction of apoptosis of cells, occurred. Disulfides 171-180 P53 Homo sapiens 62-65 16709241-5 2006 RESULTS: 5-FU treatment for 24 hours resulted in S phase arrests, p53 accumulation, up-regulation of p53-target genes on DNA damage response (ATF3, GADD34, GADD45A, PCNA), cell cycle-regulatory (CDKN1A), and apoptosis-regulatory pathways (FAS), and apoptosis induction in the parental and resistant cell lines. Fluorouracil 9-13 P53 Homo sapiens 66-69 16709241-5 2006 RESULTS: 5-FU treatment for 24 hours resulted in S phase arrests, p53 accumulation, up-regulation of p53-target genes on DNA damage response (ATF3, GADD34, GADD45A, PCNA), cell cycle-regulatory (CDKN1A), and apoptosis-regulatory pathways (FAS), and apoptosis induction in the parental and resistant cell lines. Fluorouracil 9-13 P53 Homo sapiens 101-104 16631755-1 2006 Doxorubicin, cis-diamminedichloroplatinum (II) and 5-fluorouracil used in chemotherapy induce apoptosis in Hep3B cells in the absence of p53, p73, and functional Fas. Fluorouracil 51-65 P53 Homo sapiens 137-140 16827107-5 2006 MATERIALS AND METHODS: Immunohistochemistry was employed to analyze the protein expression of p53, deltaNp73 and deltaNp63 in paraffin-embedded tumor samples from 132 well-characterized lung cancer patients. Paraffin 126-134 P53 Homo sapiens 94-97 16686938-2 2006 Here, we address the individual role of p53 and its transcriptional targets, p21CIP/WAF-1 and Bax, on apoptosis induced by individual components of multimodal anticancer therapy, i.e. 5-fluorouracil (5-FU), ionising gamma-radiation (IR) and heat shock/hyperthermia. Fluorouracil 184-198 P53 Homo sapiens 40-43 16686938-2 2006 Here, we address the individual role of p53 and its transcriptional targets, p21CIP/WAF-1 and Bax, on apoptosis induced by individual components of multimodal anticancer therapy, i.e. 5-fluorouracil (5-FU), ionising gamma-radiation (IR) and heat shock/hyperthermia. Fluorouracil 200-204 P53 Homo sapiens 40-43 16686938-10 2006 In contrast, loss of p21CIP/WAF-1 or, to a lesser extent, p53 sensitized predominantly for 5-FU and IR. Fluorouracil 91-95 P53 Homo sapiens 58-61 16601678-1 2006 The serine/threonine kinase HIPK2 phosphorylates the p53 protein at Ser 46, thus promoting p53-dependent gene expression and subsequent apoptosis. Serine 68-71 P53 Homo sapiens 53-56 16601678-1 2006 The serine/threonine kinase HIPK2 phosphorylates the p53 protein at Ser 46, thus promoting p53-dependent gene expression and subsequent apoptosis. Serine 68-71 P53 Homo sapiens 91-94 16544101-3 2006 Apoptosis induced in HeLa cells at 24 h of cisplatin treatment was confirmed by nuclear fragmentation, increase in subdiploid population and the enhanced activation of ERK and upregulation of p53. Cisplatin 43-52 P53 Homo sapiens 192-195 16611376-0 2006 In vitro folate deficiency induces apoptosis by a p53, Fas (Apo-1, CD95) independent, bcl-2 related mechanism in phytohaemagglutinin-stimulated human peripheral blood lymphocytes. Folic Acid 9-15 P53 Homo sapiens 50-53 16687915-4 2006 If a cell stays in mitosis too long, (e.g. mitotic arrest caused by Taxol or nocodazole), then p53 accumulates. Paclitaxel 68-73 P53 Homo sapiens 95-98 16611376-4 2006 The results indicate that p53 expression was downregulated in folate-deficient lymphocytes when compared with the control lymphocytes during the relevant period of S phase accumulation and apoptosis. Folic Acid 62-68 P53 Homo sapiens 26-29 16611376-9 2006 These results suggest that IL-2 depletion by folate deficiency in lymphocytes reduces the bcl-2 level, thereby triggering deoxynucleoside triphosphate pool imbalance and p53-independent apoptosis. Folic Acid 45-51 P53 Homo sapiens 170-173 16651424-4 2006 NIC-1 inhibited p53 by inhibiting its activating phosphorylations at Ser(15), Ser(20), and Ser(392) as well as nuclear localization. Serine 69-72 P53 Homo sapiens 16-19 16651424-4 2006 NIC-1 inhibited p53 by inhibiting its activating phosphorylations at Ser(15), Ser(20), and Ser(392) as well as nuclear localization. Serine 78-81 P53 Homo sapiens 16-19 16651424-4 2006 NIC-1 inhibited p53 by inhibiting its activating phosphorylations at Ser(15), Ser(20), and Ser(392) as well as nuclear localization. Serine 78-81 P53 Homo sapiens 16-19 16651424-5 2006 In addition, we found that inhibition of p53 by NIC-1 mainly occurs through mammalian target of rapamycin (mTOR) using phosphatidylinositol 3-kinase (PI3K)-Akt/protein kinase B (PKB) pathway as the mTOR inhibitor, rapamycin treatment abrogated NIC-1 inhibition of p53 and reversed the chemoresistance. Sirolimus 96-105 P53 Homo sapiens 41-44 16651424-5 2006 In addition, we found that inhibition of p53 by NIC-1 mainly occurs through mammalian target of rapamycin (mTOR) using phosphatidylinositol 3-kinase (PI3K)-Akt/protein kinase B (PKB) pathway as the mTOR inhibitor, rapamycin treatment abrogated NIC-1 inhibition of p53 and reversed the chemoresistance. Sirolimus 96-105 P53 Homo sapiens 264-267 16630142-4 2006 Furthermore, MCS-C2 induced cell cycle arrest in the G1 phase through the upregulated phosphorylation of the p53 protein at Ser-15 and activation of its downstream target gene p21WAF1/CIP1. Serine 124-127 P53 Homo sapiens 109-112 16721047-9 2006 The effect of p53 activation was checked by RT-PCR and transfections in HCT116 wt, E6 and p53-/- cells: most promoters were actively repressed upon Adriamycin treatment or following p53 transfection in p53-/- cells. Doxorubicin 148-158 P53 Homo sapiens 14-17 16721047-9 2006 The effect of p53 activation was checked by RT-PCR and transfections in HCT116 wt, E6 and p53-/- cells: most promoters were actively repressed upon Adriamycin treatment or following p53 transfection in p53-/- cells. Doxorubicin 148-158 P53 Homo sapiens 90-93 16687915-4 2006 If a cell stays in mitosis too long, (e.g. mitotic arrest caused by Taxol or nocodazole), then p53 accumulates. Nocodazole 77-87 P53 Homo sapiens 95-98 16721047-9 2006 The effect of p53 activation was checked by RT-PCR and transfections in HCT116 wt, E6 and p53-/- cells: most promoters were actively repressed upon Adriamycin treatment or following p53 transfection in p53-/- cells. Doxorubicin 148-158 P53 Homo sapiens 90-93 16687923-4 2006 A recent study using RNA interference in human SCC-derived cell lines shows that DeltaNp63alpha mediates an essential survival function in human SCC cells by virtue of its ability to suppress the pro-apoptotic function of the related p53 family member p73. deltanp63alpha 81-95 P53 Homo sapiens 234-237 16721047-9 2006 The effect of p53 activation was checked by RT-PCR and transfections in HCT116 wt, E6 and p53-/- cells: most promoters were actively repressed upon Adriamycin treatment or following p53 transfection in p53-/- cells. Doxorubicin 148-158 P53 Homo sapiens 90-93 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Arginine 66-69 P53 Homo sapiens 47-50 16527552-10 2006 Both Wortmannin and PD98059 elevated the level of p53 expression strikingly, however, only PD98059 suppressed the up-regulation trend of c-Myc expression induced by etoposide. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 20-27 P53 Homo sapiens 50-53 16700663-5 2006 An immunohistochemical method was used to investigate the expression of COX-2 and p53 proteins on formalin-fixed, paraffin-embedded tissue specimens of squamous cell carcinomas (SCC), basal cell carcinomas (BCC), Bowen"s disease (BD), actinic keratosis (AK) and porokeratosis. Paraffin 114-122 P53 Homo sapiens 82-85 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033].

Arginine 88-91 P53 Homo sapiens 47-50 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Arginine 88-91 P53 Homo sapiens 47-50 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Arginine 88-91 P53 Homo sapiens 47-50 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Serine 170-173 P53 Homo sapiens 47-50 16529824-8 2006 Our study thus demonstrates that morphine induces Jurkat cell apoptosis through FADD/p53, anti-apoptotic PI3K/Akt and NF-kappaB pathways. Morphine 33-41 P53 Homo sapiens 85-88 16529824-0 2006 Morphine promotes Jurkat cell apoptosis through pro-apoptotic FADD/P53 and anti-apoptotic PI3K/Akt/NF-kappaB pathways. Morphine 0-8 P53 Homo sapiens 67-70 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Serine 192-195 P53 Homo sapiens 47-50 16529824-5 2006 Furthermore, suppression of endogenous p53 expression by RNA interference technology considerably attenuated the morphine-induced apoptosis. Morphine 113-121 P53 Homo sapiens 39-42 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Serine 192-195 P53 Homo sapiens 47-50 16731756-9 2006 We conclude that separate from effects on sensitivity to the acute cytotoxic effect of cisplatin, loss of MMR, especially when combined with loss of p53, results in rapid evolution of cisplatin resistance during sequential rounds of drug exposure that is likely mediated by enhanced mutagenic translesion synthesis. Cisplatin 184-193 P53 Homo sapiens 149-152 16731756-10 2006 The DNA damage response activated by cisplatin is accompanied by a p53- and MMR-dependent increase in homologous recombination even between adduct-free sequences. Cisplatin 37-46 P53 Homo sapiens 67-70 16731756-0 2006 DNA mismatch repair and p53 function are major determinants of the rate of development of cisplatin resistance. Cisplatin 90-99 P53 Homo sapiens 24-27 16731759-7 2006 Additional studies revealed that GSE causes DNA damage-induced activation of ataxia telangiectasia mutated kinase and Chk2, as well as p53 Ser(15) phosphorylation and its translocation to mitochondria, suggesting this to be an additional mechanism for apoptosis induction. Serine 139-142 P53 Homo sapiens 135-138 16731756-4 2006 Loss of either MMR or p53 alone increased the rate of development of resistance to cisplatin by 1.8- and 2.4-fold, respectively; however, loss of both MMR and p53 increased the rate by 4.8-fold. Cisplatin 83-92 P53 Homo sapiens 22-25 16731756-4 2006 Loss of either MMR or p53 alone increased the rate of development of resistance to cisplatin by 1.8- and 2.4-fold, respectively; however, loss of both MMR and p53 increased the rate by 4.8-fold. Cisplatin 83-92 P53 Homo sapiens 159-162 16518417-4 2006 On the other hand, pretreatment with dicoumarol enhanced cytotoxicity of CDDP in three cell lines with wild type of p53 (RT112, 253J and LNCap), but not in three other cell lines with mutant p53 or in RT112 stable transfectants with a dominant-negative mutant of p53. Cisplatin 73-77 P53 Homo sapiens 116-119 16731756-8 2006 In the p53- and MMR-proficient cells, cisplatin induced a 17-fold increase in homologous recombination even when the recombining sequences that did not contain cisplatin adducts; the magnitude of induction was even greater in cells that had lost either one or both functions. Cisplatin 38-47 P53 Homo sapiens 7-10 16609366-9 2006 CONCLUSION: The present report indicates that the codon 72 polymorphism in the p53 gene may be a predictor of tamoxifen response, suggesting that breast cancer patients lacking the Pro72 allele might be candidates for other therapies. Tamoxifen 110-119 P53 Homo sapiens 79-82 16761419-4 2006 RESULTS: The frequencies of p53 Arg homozygosity in cervical squamous cancer, cervical adenocarcinoma and CIN (II - III) were 58.020%, 55.55% and 59.09% respectively, greater than those of p53 Arg/Pro heterozygosity (30.86%, 27.78%, 21.59%) and those of p53 Pro homozygosity (11.12%, 16.67%, 19.32%). Arginine 32-35 P53 Homo sapiens 28-31 16761419-4 2006 RESULTS: The frequencies of p53 Arg homozygosity in cervical squamous cancer, cervical adenocarcinoma and CIN (II - III) were 58.020%, 55.55% and 59.09% respectively, greater than those of p53 Arg/Pro heterozygosity (30.86%, 27.78%, 21.59%) and those of p53 Pro homozygosity (11.12%, 16.67%, 19.32%). Arginine 193-196 P53 Homo sapiens 28-31 16761419-5 2006 The normal cervical samples also showed less frequency of p53 Arg homozygosity (23.33%) than cervical squamous cancer. Arginine 62-65 P53 Homo sapiens 58-61 16518417-0 2006 Dicoumarol potentiates cisplatin-induced apoptosis mediated by c-Jun N-terminal kinase in p53 wild-type urogenital cancer cell lines. Cisplatin 23-32 P53 Homo sapiens 90-93 16596182-2 2006 While the role of p53 in CDDP-induced cell death has been stressed, evidence exists that CDDP can also kill p53-mutated cells. Cisplatin 89-93 P53 Homo sapiens 108-111 16596182-8 2006 Therefore, the JNK pathway appears to be an ideal target for the modulation of the lethal action of CDDP in multiple types of p53-mutated cells. Cisplatin 100-104 P53 Homo sapiens 126-129 16761419-9 2006 The frequency of p53 Arg homozygosity in HRHPV E6-positive cervical squamous cancers (64.06%) was greater than in HRHPV E6-negative cervical squamous cancers (35.29%) and in HRHPV E6-positive normal samples (33.33%). Arginine 21-24 P53 Homo sapiens 17-20 16518417-4 2006 On the other hand, pretreatment with dicoumarol enhanced cytotoxicity of CDDP in three cell lines with wild type of p53 (RT112, 253J and LNCap), but not in three other cell lines with mutant p53 or in RT112 stable transfectants with a dominant-negative mutant of p53. Cisplatin 73-77 P53 Homo sapiens 191-194 21144291-9 2006 (4)The expression levels of P53, P21, Fas, FasL and Bax were remarkably up-regulated after treatment with MSA. methylselenic acid 106-109 P53 Homo sapiens 28-31 16518417-4 2006 On the other hand, pretreatment with dicoumarol enhanced cytotoxicity of CDDP in three cell lines with wild type of p53 (RT112, 253J and LNCap), but not in three other cell lines with mutant p53 or in RT112 stable transfectants with a dominant-negative mutant of p53. Cisplatin 73-77 P53 Homo sapiens 191-194 21144296-12 2006 Meanwhile the apoptotic rate of A549 cells was 28.99%+-1.07% in Ad-p53+DDP group, which was significantly higher than that in Ad-p53 group (15.35%+-1.31%, P < 0.001) and DDP group (1.74%+-0.77%, P < 0.001). Cisplatin 71-74 P53 Homo sapiens 67-70 21144296-13 2006 The apoptotic rate of GLC-82 cells was 62.98%+-2.43% in Ad-p53+DDP group, which was significantly higher than that in Ad-p53 group (20.88%+-0.71%, P < 0.001) and DDP group (6.91%+-1.52%, P < 0.001). Cisplatin 63-66 P53 Homo sapiens 59-62 16518417-5 2006 In RT112 and LNCap, CDDP induced p53 and p21 expression, while pretreatment of dicoumarol suppressed induction of p53/p21 and resulted in sequential activation of c-Jun N-terminal kinase (JNK) in a time-dependent manner. Cisplatin 20-24 P53 Homo sapiens 33-36 16518417-7 2006 These results suggested that dicoumarol could enhance cytotoxicity of CDDP in urogenital cancer cells with wild-type p53 through the p53/p21/JNK pathways. Cisplatin 70-74 P53 Homo sapiens 117-120 16518417-7 2006 These results suggested that dicoumarol could enhance cytotoxicity of CDDP in urogenital cancer cells with wild-type p53 through the p53/p21/JNK pathways. Cisplatin 70-74 P53 Homo sapiens 133-136 16518418-3 2006 In FaDu xenografts, a poorly differentiated tumor-expressing mutant p53, the cure rate was increased from 30% with irinotecan alone to 100% with the combination of irinotecan and MSC. Irinotecan 115-125 P53 Homo sapiens 68-71 16518418-3 2006 In FaDu xenografts, a poorly differentiated tumor-expressing mutant p53, the cure rate was increased from 30% with irinotecan alone to 100% with the combination of irinotecan and MSC.

Oligonucleotides 137-152 P53 Homo sapiens 170-173 16618762-1 2006 SIRT1 and other NAD-dependent deacetylases have been implicated in control of cellular responses to stress and in tumorigenesis through deacetylation of important regulatory proteins, including p53 and the BCL6 oncoprotein. NAD 16-19 P53 Homo sapiens 194-197 16287077-9 2006 Cells treated with E2 or 4-OHE2 at doses of 0.007 nM and 70 nM and 2-OHE2 only at a higher dose (3.6 microM) exhibited a 5 bp deletion in p53 exon 4. Estradiol 19-21 P53 Homo sapiens 138-141 16625088-12 2006 Expression of p53 was present in 92% of the FS areas and in only 3% of adjacent DFSP areas. phenylalanylserine 44-46 P53 Homo sapiens 14-17 16585172-9 2006 Mitochondrial extracts from p53+/+ cells more efficiently stimulated (32)P-dCTP incorporation into a uracil-oligonucleotide.

Oligonucleotides 97-113 P53 Homo sapiens 12-15 16585172-10 2006 Recombinant p53 complemented p53-/- mitochondrial extract repair of uracil or 8-oxo-G-containing oligonucleotides. Oligonucleotides 97-113 P53 Homo sapiens 29-32 16585172-11 2006 As a measure of DNA glycosylase activity, p53+/+ mitochondrial extracts more efficiently incised uracil or 8-oxo-G oligonucleotides, although recombinant p53 could not stimulate oligonucleotide incision. Oligonucleotides 115-130 P53 Homo sapiens 42-45 16585172-13 2006 p53+/+ mitochondrial extracts had higher DNA polymerase-gamma activity measured by (32)P-dCTP incorporation into a single-nucleotide gap oligonucleotide, and recombinant p53 complemented p53-/- mitochondrial extract DNA polymerase-gamma activity. 2'-deoxycytidine 5'-triphosphate 89-93 P53 Homo sapiens 0-3 16585172-13 2006 p53+/+ mitochondrial extracts had higher DNA polymerase-gamma activity measured by (32)P-dCTP incorporation into a single-nucleotide gap oligonucleotide, and recombinant p53 complemented p53-/- mitochondrial extract DNA polymerase-gamma activity. 2'-deoxycytidine 5'-triphosphate 89-93 P53 Homo sapiens 170-173 16585172-13 2006 p53+/+ mitochondrial extracts had higher DNA polymerase-gamma activity measured by (32)P-dCTP incorporation into a single-nucleotide gap oligonucleotide, and recombinant p53 complemented p53-/- mitochondrial extract DNA polymerase-gamma activity. 2'-deoxycytidine 5'-triphosphate 89-93 P53 Homo sapiens 170-173 16616141-0 2006 Evidence that low doses of Taxol enhance the functional transactivatory properties of p53 on p21 waf promoter in MCF-7 breast cancer cells. Paclitaxel 27-32 P53 Homo sapiens 86-89 16616141-1 2006 In the present study, we evidence how in breast cancer cells low doses of Taxol for 18 h determined the upregulation of p53 and p21 waf expression concomitantly with a decrease of the anti-apoptotic Bcl-2.

Arginine 124-127 P53 Homo sapiens 210-213 16228292-2 2005 We characterized the effects of bcl-2 antisense and cisplatin combination therapy in two human isogenic breast carcinoma cells p53(+)MCF-7 and p53(-)MCF-7/E6. Cisplatin 52-61 P53 Homo sapiens 143-146 16311126-6 2005 A p53 protein immunohistochemical analysis was performed on paraffin-embedded tissues. Paraffin 60-68 P53 Homo sapiens 2-5 16311126-11 2005 Of 10 serous papillary carcinomas, 8 (80%) for which paraffin blocks were available overexpressed the p53 protein. Paraffin 53-61 P53 Homo sapiens 102-105 16099193-7 2005 After cisplatin-induced DNA damage, the increasing levels of p53 lead to the trans-activation of a number of genes but not of p21(Waf1/Cip1), preferentially directing TGCT cells into apoptosis or programmed cell death, both via the mitochondrial and the death receptor apoptosis pathways. Cisplatin 6-15 P53 Homo sapiens 61-64 16375215-4 2005 Immunostaining for p53 protein was performed on formalin-fixed, paraffin-embedded tissue sections, using the alkaline phosphatase antialkaline phosphatase (APAAP) method. Paraffin 64-72 P53 Homo sapiens 19-22 16169939-4 2005 We further analyzed the signaling pathways underlying these effects, and we showed that both RDCs and cisplatin induced p53 and p73 protein levels but with different intensities and kinetics. Cisplatin 102-111 P53 Homo sapiens 120-123 16272802-6 2005 As for the association with environmental factors, p53 mutations occurred with higher frequency in patients with a daily intake of spicy foods and in those who used unboiled well water in the low-incidence area. Water 179-184 P53 Homo sapiens 51-54 16272802-8 2005 Thus, higher frequency of spicy food intake and use of unboiled well water may be risk factors of esophageal cancer via p53 mutations in China. Water 69-74 P53 Homo sapiens 120-123 16226226-10 2005 In contrast, p53 mutated Huh-7 hepatocellular cancer cells proved to be less sensitive towards cetuximab, but when combined with TKIs or fluvastatin or doxorubicin a pronounced reduction of cell growth was observed. Doxorubicin 152-163 P53 Homo sapiens 13-16 16307686-2 2005 Furthermore, the polymorphism at codon 72 (encoding either arginine or proline) of the p53 tumor-suppressor gene is discussed as a possible determinant for cancer risk. Arginine 59-67 P53 Homo sapiens 87-90 16225614-0 2005 Differential effects of 5-aminolaevulinic acid photodynamic therapy and psoralen + ultraviolet A therapy on p53 phosphorylation in normal human skin in vivo. Ficusin 72-80 P53 Homo sapiens 108-111 16552971-1 2005 BACKGROUND & OBJECTIVE: P53 pathway plays a critical role in carcinogenesis of pancreatic carcinoma. Adenosine Monophosphate 12-15 P53 Homo sapiens 28-31 16288013-2 2005 Here, we describe the gene expression profiles associated with four microenvironmental components of the inflammatory response (NO*, H2O2, DNA replication arrest, and hypoxia) that result in p53 stabilization and activation. Hydrogen Peroxide 133-137 P53 Homo sapiens 191-194 16014005-7 2005 We have also shown that FDH elevation results in p53 phosphorylation at Ser-6 and Ser-20 in the p53 transactivation domain, and Ser-392 in the C-terminal domain, but only Ser-6 is strictly required to mediate FDH effects. Serine 72-75 P53 Homo sapiens 49-52 16225614-6 2005 Importantly, PUVA treatment resulted in p53 kinase activation, as defined by p53 modification at AT (serine-15) and CK2/FACT (serine-392) sites within the proliferative compartment. Serine 101-107 P53 Homo sapiens 40-43 16312222-5 2005 All nucleotides in the TP53 gene from exon 2-9 are included on the chip by synthesis and application of sequence-specific oligonucleotides. Oligonucleotides 122-138 P53 Homo sapiens 23-27 16225614-6 2005 Importantly, PUVA treatment resulted in p53 kinase activation, as defined by p53 modification at AT (serine-15) and CK2/FACT (serine-392) sites within the proliferative compartment. Serine 101-107 P53 Homo sapiens 77-80 16120770-9 2005 We also observed a decrease in E7 expression with a concurrent increase in p53 protein levels upon cotreatment with shRNA and cisplatin over that seen with individual treatment alone. Cisplatin 126-135 P53 Homo sapiens 75-78 16271069-12 2005 Noticeably, alcohol consumption could enhance this peculiar spectrum of p53 mutation in ESCC. Alcohols 12-19 P53 Homo sapiens 72-75 16246896-0 2005 Copper alters the conformation and transcriptional activity of the tumor suppressor protein p53 in human Hep G2 cells. Copper 0-6 P53 Homo sapiens 92-95 16246896-2 2005 To test the effect of copper on the transcriptional activity of p53, Hep G2 cells were transiently transfected with a luciferase reporter gene downstream from multiple p53 response elements. Copper 22-28 P53 Homo sapiens 64-67 16246896-5 2005 Oligonucleotide arrays representing 145 known p53-associated genes were hybridized with biotinylated cDNAs from mRNA extracted from control and copper-treated Hep G2 cells. Oligonucleotides 0-15 P53 Homo sapiens 46-49 16246896-7 2005 Although control Hep G2 cells synthesize wild-type p53, immunocytochemistry identified not only wild type, but also mutant p53 in the presence of copper and other agents that induce oxidative damage. Copper 146-152 P53 Homo sapiens 123-126 16246896-8 2005 Thus, this report not only identifies genes that may play a role in copper-mediated apoptosis, but also suggests that copper-induced oxidative processes result in the synthesis of mutant p53 with altered transcriptional properties. Copper 68-74 P53 Homo sapiens 187-190 16246896-8 2005 Thus, this report not only identifies genes that may play a role in copper-mediated apoptosis, but also suggests that copper-induced oxidative processes result in the synthesis of mutant p53 with altered transcriptional properties. Copper 118-124 P53 Homo sapiens 187-190 16096850-7 2005 In OMS, apoptosis increased, cell proliferation decreased, and p53/p21 expression increased more pronounced following CDDP+RT. Cisplatin 118-122 P53 Homo sapiens 63-66 16227609-0 2005 DNA damage-induced phosphorylation of MdmX at serine 367 activates p53 by targeting MdmX for Mdm2-dependent degradation. Serine 46-52 P53 Homo sapiens 67-70 16081268-7 2005 Resveratrol consistently increased by > or =6-fold Mdm2 expression and other downstream p53 effectors, but not p53 itself at 24 h. Subsequent cell cycle analysis indicated a significant accumulation of cells in G2/M, and a decrease in G1/G0 suggesting a G2/M blockade. Resveratrol 0-11 P53 Homo sapiens 91-94 16120770-10 2005 Our results provide strong evidence that loss of E6 and E7 results in increased sensitivity to cisplatin, probably because of increased p53 levels. Cisplatin 95-104 P53 Homo sapiens 136-139 16188274-7 2005 Refolding was commenced from unfolded protein in 8M urea, and both the Trp53 to C25-TNB distance and the Trp53 to C62-TNB distance were found to contract upon dilution of urea. Urea 171-175 P53 Homo sapiens 71-76 16087277-5 2005 CsA induced a senescence-associated growth arrest, in U87-MG glioma cells with functional p53, while in U373 and T98G glioma cells with mutated p53, CsA treatment triggered cell death associated with alterations of cell morphology, cytoplasm vacuolation, and condensation of chromatin. Cyclosporine 0-3 P53 Homo sapiens 90-93 16087277-5 2005 CsA induced a senescence-associated growth arrest, in U87-MG glioma cells with functional p53, while in U373 and T98G glioma cells with mutated p53, CsA treatment triggered cell death associated with alterations of cell morphology, cytoplasm vacuolation, and condensation of chromatin. Cyclosporine 149-152 P53 Homo sapiens 144-147 16188274-7 2005 Refolding was commenced from unfolded protein in 8M urea, and both the Trp53 to C25-TNB distance and the Trp53 to C62-TNB distance were found to contract upon dilution of urea. Urea 171-175 P53 Homo sapiens 105-110 16230611-4 2005 Dizocilpine reduces the phosphorylation of cAMP-responsive element binding protein, suppresses the expression of cyclin D1, up-regulates the cell cycle regulators and tumor suppressor proteins p21 and p53, and increases the number of lung adenocarcinoma cells in the G(2) and S phases of the cell cycle. Dizocilpine Maleate 0-11 P53 Homo sapiens 201-204 16123044-6 2005 In this regard, it has been recently observed that the prolyl isomerase Pin1 can interact with proteins phosphorylated on serine or threonine residues that precede prolines (pS/T-P), such as the transcription factors p53 and c-Jun, thereby controlling their activity by promoting the cis-trans isomerization of these pS/T-P bonds. Serine 122-128 P53 Homo sapiens 217-220 16123044-6 2005 In this regard, it has been recently observed that the prolyl isomerase Pin1 can interact with proteins phosphorylated on serine or threonine residues that precede prolines (pS/T-P), such as the transcription factors p53 and c-Jun, thereby controlling their activity by promoting the cis-trans isomerization of these pS/T-P bonds. Threonine 132-141 P53 Homo sapiens 217-220 16234232-5 2005 The H2 helix of p53 structurally mimics the binding of ssDNA to the oligonucleotide/oligosaccharide-binding fold. Oligonucleotides 68-83 P53 Homo sapiens 16-19 16273653-6 2005 RESULTS: The group transfected with pCMVp53 alone exhibited higher luciferase activity and higher apoptosis rate, otherwise, the p53 expression and reporter activity of PG13-CAT or P21-luc as well as cell apoptosis rate were obviously higher in the group cotransfected of pCMVp53 with pCMVHBVa, but not in the other cotransfected group. pcmvhbva 285-293 P53 Homo sapiens 40-43 16007154-3 2005 In proliferating keratinocytes, the activity of p53 is blunted by its inhibitor DeltaNp63alpha. deltanp63alpha 80-94 P53 Homo sapiens 48-51 15849742-0 2005 P73 functionally replaces p53 in Adriamycin-treated, p53-deficient breast cancer cells. Doxorubicin 33-43 P53 Homo sapiens 26-29 16109433-11 2005 Activation of genes associated with cell cycle arrest, the p53 and TNF-related pathways, and chemokines and chemokine receptors, were particularly evident for the reactive oxygen compounds. reactive oxygen compounds 163-188 P53 Homo sapiens 59-62 16103882-7 2005 Suppression of p53 activation by bFGF was frequently but not always accompanied by upregulation of the p53-inhibitory protein MDM2 and/or phosphorylation of MDM2 at serine 166, and was associated with impaired transcriptional activation of the p53 target gene p21. Serine 165-171 P53 Homo sapiens 15-18 16230424-5 2005 We observed an increased risk of ESCC associated with the P53 Pro/Pro (OR, 1.83; 95% CI, 1.43-2.35; P < 0.001) or MDM2 GG (OR, 1.49; 95% CI, 1.16-1.91; P = 0.002) genotype, compared with the P53 Arg/Arg or MDM2 TT genotype, respectively. Arginine 198-201 P53 Homo sapiens 58-61 16230424-5 2005 We observed an increased risk of ESCC associated with the P53 Pro/Pro (OR, 1.83; 95% CI, 1.43-2.35; P < 0.001) or MDM2 GG (OR, 1.49; 95% CI, 1.16-1.91; P = 0.002) genotype, compared with the P53 Arg/Arg or MDM2 TT genotype, respectively. Arginine 202-205 P53 Homo sapiens 58-61 16243804-9 2005 CONCLUSION: Our study indicates that breast cancer patients with the Pro/Pro variant may be less sensitive to anthracycline-based treatment than those with the Pro/Arg or Arg/Arg variant and suggests that analysis of p53 codon 72 polymorphism may provide a simple predictive marker for selecting the right breast cancer patients to anthracycline-based neoadjuvant chemotherapy in clinical setting. Anthracyclines 110-123 P53 Homo sapiens 217-220 15849742-0 2005 P73 functionally replaces p53 in Adriamycin-treated, p53-deficient breast cancer cells. Doxorubicin 33-43 P53 Homo sapiens 53-56 16204068-2 2005 We found that 5-fluorouracil (5-FU) and oxaliplatin only sensitized p53 wild-type (WT) colorectal cancer cell lines to Fas-mediated apoptosis. Fluorouracil 14-28 P53 Homo sapiens 68-71 16163384-3 2005 Here, we report that the tumor suppressor molecule p53 has a novel role in maintaining mitochondrial genetic stability through its ability to translocate to mitochondria and interact with mtDNA polymerase gamma (pol gamma) in response to mtDNA damage induced by exogenous and endogenous insults including ROS. Reactive Oxygen Species 305-308 P53 Homo sapiens 51-54 16163384-6 2005 This study provides a mechanistic explanation for the accelerating genetic instability and increased ROS stress in cancer cells associated with loss of p53. Reactive Oxygen Species 101-104 P53 Homo sapiens 152-155 16204068-2 2005 We found that 5-fluorouracil (5-FU) and oxaliplatin only sensitized p53 wild-type (WT) colorectal cancer cell lines to Fas-mediated apoptosis. Fluorouracil 30-34 P53 Homo sapiens 68-71 16204068-3 2005 In contrast, irinotecan (CPT-11) and tomudex sensitized p53 WT, mutant, and null cells to Fas-mediated cell death. Irinotecan 13-23 P53 Homo sapiens 56-59 16204068-3 2005 In contrast, irinotecan (CPT-11) and tomudex sensitized p53 WT, mutant, and null cells to Fas-mediated cell death. Irinotecan 25-31 P53 Homo sapiens 56-59 16204068-4 2005 Furthermore, CPT-11 and tomudex, but not 5-FU or oxaliplatin, up-regulated Fas cell surface expression in a p53-independent manner. Irinotecan 13-19 P53 Homo sapiens 108-111 15905205-2 2005 The codon 72 polymorphism has been proposed to alter the phenotype of TP53 mutations, and TP53 mutations have been reported to occur preferentially on the arginine allele. Arginine 155-163 P53 Homo sapiens 90-94 16204068-5 2005 In addition, increased Fas cell surface expression in p53 mutant and null cell lines in response to CPT-11 and tomudex was accompanied by only a slight increase in total Fas mRNA and protein expression, suggesting that these agents trigger p53-independent trafficking of Fas to the plasma membrane. Irinotecan 100-106 P53 Homo sapiens 54-57 16204068-6 2005 Treatment with CPT-11 or tomudex induced STAT1 phosphorylation (Ser727) in the p53-null HCT116 cell line but not the p53 WT cell line. Irinotecan 15-21 P53 Homo sapiens 79-82 16204068-10 2005 We conclude that CPT-11 and tomudex may be more effective than 5-FU and oxaliplatin in the treatment of p53 mutant colorectal cancer tumors by sensitizing them to Fas-mediated apoptosis in a STAT1-dependent manner. Irinotecan 17-23 P53 Homo sapiens 104-107 16054204-8 2005 The p21 arginine allele was significantly associated with CaCx in the p53 proline non-homozygous group of subjects (OR(age-adjusted) = 2.68; 95% CI: 1.21-5.91; P = 0.01), and specifically in the p53 heterozygous group (OR(age-adjusted) = 2.91; 95% CI = 1.12-7.56; P = 0.03).

Cisplatin 0-9 P53 Homo sapiens 21-24 16232203-5 2005 Wt-p53 production in cultured tumor cells and xenografts treated with the combination of AdEgr-p53 and cisplatin were detected by enzyme-linked immunosorbent assays. Cisplatin 103-112 P53 Homo sapiens 3-6 16232203-7 2005 We found that p53 was produced in tumor cells and xenografts treated with a combination of AdEgr-p53 and cisplatin. Cisplatin 105-114 P53 Homo sapiens 14-17 16232203-10 2005 Cisplatin-inducible p53 gene therapy may provide a means to control transgene expression while enhancing the effectiveness of commonly used chemotherapeutic agents. Cisplatin 0-9 P53 Homo sapiens 20-23 16203772-1 2005 PURPOSE: The Arg/Pro polymorphism in codon 72 of p53 was recently associated with age of onset of colorectal cancer in Lynch syndrome. Arginine 13-16 P53 Homo sapiens 49-52 16203773-0 2005 Reduced cisplatin sensitivity of head and neck squamous cell carcinoma cell lines correlates with mutations affecting the COOH-terminal nuclear localization signal of p53. Cisplatin 8-17 P53 Homo sapiens 167-170 16203773-11 2005 Cisplatin sensitivity was highly reduced in the group with loss of nuclear p53 signal compared with those with detectable nuclear signal. Cisplatin 0-9 P53 Homo sapiens 75-78 16203773-13 2005 CONCLUSION: Taken together, these data suggest that "loss of nuclear p53 signal" correlates with cisplatin resistance in HNSCC. Cisplatin 97-106 P53 Homo sapiens 69-72 16018998-8 2005 Furthermore, the survival rate of p53(-/-)/Mdm2(-/-) cells exposed to thapsigargin was increased when cultured at 32 degrees C compared with 37 degrees C. In conclusion, mild hypothermia protects cells from a variety of stress by p53-dependent and p53-independent mechanisms. Thapsigargin 70-82 P53 Homo sapiens 34-37 16018998-8 2005 Furthermore, the survival rate of p53(-/-)/Mdm2(-/-) cells exposed to thapsigargin was increased when cultured at 32 degrees C compared with 37 degrees C. In conclusion, mild hypothermia protects cells from a variety of stress by p53-dependent and p53-independent mechanisms. Thapsigargin 70-82 P53 Homo sapiens 230-233 16018998-8 2005 Furthermore, the survival rate of p53(-/-)/Mdm2(-/-) cells exposed to thapsigargin was increased when cultured at 32 degrees C compared with 37 degrees C. In conclusion, mild hypothermia protects cells from a variety of stress by p53-dependent and p53-independent mechanisms. Thapsigargin 70-82 P53 Homo sapiens 230-233 16054204-8 2005 The p21 arginine allele was significantly associated with CaCx in the p53 proline non-homozygous group of subjects (OR(age-adjusted) = 2.68; 95% CI: 1.21-5.91; P = 0.01), and specifically in the p53 heterozygous group (OR(age-adjusted) = 2.91; 95% CI = 1.12-7.56; P = 0.03). Arginine 8-16 P53 Homo sapiens 195-198 20818013-5 2005 Specifically, we present an improved immobilization method that covalently anchors one end (5" end) of a dual labelled (5"-thiol, 3"-biotin) p53 DNA molecule onto a gold substrate via gold-thiol chemistry, whilst the biotinylated 3" end is available for "pick-up" using a streptavidin modified AFM tip.

Arginine 114-122 P53 Homo sapiens 44-47 16199549-1 2005 The polymorphic variants at codon 72 of the p53 gene were shown to be functionally distinct in vitro, whereby the arginine (arg) variant induces apoptosis more efficiently than the proline (pro) variant. Arginine 114-117 P53 Homo sapiens 44-47 16043423-6 2005 However, following the onset of calcium-induced differentiation, basal levels of p53 were nearly undetectable by 12 days of differentiation when global repair activity was unaffected. Calcium 32-39 P53 Homo sapiens 81-84 16087156-0 2005 Knockdown of p53 by RNAi in ES cells facilitates RA-induced differentiation into muscle cells. Tretinoin 49-51 P53 Homo sapiens 13-16 16087156-5 2005 With RA treatment, silencing of p53 by RNAi in ES cells leads to dominant muscle cell production but lack of neuronal cell, indicating that p53 indeed plays a role during muscle and neuronal fate commitment. Tretinoin 5-7 P53 Homo sapiens 32-35 16087156-5 2005 With RA treatment, silencing of p53 by RNAi in ES cells leads to dominant muscle cell production but lack of neuronal cell, indicating that p53 indeed plays a role during muscle and neuronal fate commitment. Tretinoin 5-7 P53 Homo sapiens 140-143 16043423-7 2005 Following ultraviolet radiation, induction of p53 following ultraviolet radiation was abrogated by 6 days of calcium-induced differentiation. Calcium 109-116 P53 Homo sapiens 46-49 16202244-3 2005 Here we showed that etoposide can induce the similar degree of cell death in p53-deficient HCT 116 cells, whereas 5"-FU-mediated cell death is strongly dependent on the existence of functional p53 in HCT 116 cells. Fluorouracil 114-119 P53 Homo sapiens 193-196 16007197-0 2005 Quantitation of p53 nuclear relocation in response to stress using a yeast functional assay: effects of irradiation and modulation by heavy metal ions. Metals 140-145 P53 Homo sapiens 16-19 16007197-7 2005 Cd2+ and Hg2+, two metal ions inducing DNA damage as well as conformational changes in p53, have opposite effects on p53 relocation in response to DNA damage. Metals 19-24 P53 Homo sapiens 117-120 16166444-11 2005 CONCLUSIONS: p21 expression in colorectal cancer, especially in combination with p53 mutation, is a predictor of resistance to the combination chemotherapy with gefitinib. Gefitinib 161-170 P53 Homo sapiens 81-84 16121349-1 2005 BACKGROUND AND OBJECTIVES: To ascertain the prevalence of deregulating mutations of beta-catenin gene, and to correlate this with the occurrence of 249(serine) p53 gene mutation and hepatitis B virus infection in southern African Blacks with hepatocellular carcinoma. Serine 152-158 P53 Homo sapiens 160-163 15940259-8 2005 Interestingly, in p53 knockdown cells nearly the entire set of identified cisplatin targets fail to respond or have a diminished response to cisplatin, suggesting that many are new direct or indirect targets of p53 including GPR87, STK17A, INPP5D, FLJ11259, and EPS8L2.

Cisplatin 128-137 P53 Homo sapiens 27-30 16082224-1 2005 A common polymorphism at codon 72 in p53 gene leads to an arginine to proline aminoacidic substitution which affects in an age-dependent manner the susceptibility of cells to undergo apoptosis after oxidative stress. Arginine 58-66 P53 Homo sapiens 37-40 15983031-8 2005 Caspase-2 activation was a critical response from p53, which was markedly induced and phosphorylated in cisplatin-treated cells.

Progesterone 0-12 P53 Homo sapiens 99-102 19565011-3 2005 We have recently shown that growth inhibition of MCF-7 human breast cancer cells by progesterone is associated with P53 down-regulation. Progesterone 84-96 P53 Homo sapiens 116-119 19565011-7 2005 The inhibition of MDM2 p90 protein by progesterone was abrogated in MCF-7 cells transfected with a P53 expressing vector. Progesterone 38-50 P53 Homo sapiens 99-102 19565011-10 2005 The data indicate that expression of MDM2 p90 is regulated through a P53-dependent pathway in response to progesterone. Progesterone 106-118 P53 Homo sapiens 69-72 16085052-2 2005 The mechanism underlying this tyrosine phosphorylation is thought to involve the sequential action of two protein tyrosine kinases, Syk (p72syk) and Lyn (p53/56lyn). Tyrosine 30-38 P53 Homo sapiens 154-157 15880691-3 2005 We demonstrated that expression of wild-type p53 induced by copper or zinc significantly reduced phosphorylation of extracellular signal regulated kinase (ERK) in epithelial breast cancer MCF7 cells. Copper 60-66 P53 Homo sapiens 45-48 15880691-6 2005 Furthermore, inhibition of ERK through addition of PD98059 stimulated p53 activation in MCF7 cells and also led to upregulation of p53 downstream targets, p21 and Bax, which is a proapototic member of Bcl-2 family triggering mitochondrial pore opening. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 51-58 P53 Homo sapiens 70-73 15880691-6 2005 Furthermore, inhibition of ERK through addition of PD98059 stimulated p53 activation in MCF7 cells and also led to upregulation of p53 downstream targets, p21 and Bax, which is a proapototic member of Bcl-2 family triggering mitochondrial pore opening. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 51-58 P53 Homo sapiens 131-134 15880691-8 2005 Disruption of p53 expression attenuated the depolarization of the mitochondrial membrane and ROS generation. ros 93-96 P53 Homo sapiens 14-17 15914462-1 2005 Proline oxidase is a p53-induced redox gene that can generate reactive oxygen species (ROS) and mediate apoptosis in tumor cells.

Cyclosporine 102-115 P53 Homo sapiens 26-29 15914462-4 2005 Both proline oxidase- and p53-induced activation of NFAT were sensitive to the calcineurin inhibitors cyclosporin A and FK-506, to scavengers of ROS, and to inhibitors of calcium mobilization. Reactive Oxygen Species 145-148 P53 Homo sapiens 26-29 15914462-4 2005 Both proline oxidase- and p53-induced activation of NFAT were sensitive to the calcineurin inhibitors cyclosporin A and FK-506, to scavengers of ROS, and to inhibitors of calcium mobilization.

Acridines 0-8 P53 Homo sapiens 30-33 16177561-4 2005 We also found that several randomly chosen acridine derivatives, including 9-aminoacridine, amsacrine, quinacrine and acridine orange, induced p53 transcriptional activity. Acridines 43-51 P53 Homo sapiens 143-146 16177561-5 2005 All these acridine derivatives stabilized p53 protein by blocking its ubiquitination, without phosphorylation of ser15 or ser20 on p53. Acridines 10-18 P53 Homo sapiens 42-45 16177561-6 2005 Furthermore, acridine derivatives induced p53-dependent cell death. Acridines 13-21 P53 Homo sapiens 42-45 16177561-7 2005 Knockout of Bax, a p53 target and a key cell death inducer in both intrinsic and extrinsic apoptotic pathways, blocked acridine derivatives from inducing cell death. Acridines 119-127 P53 Homo sapiens 19-22 16177561-9 2005 Our results reveal that DNA-intercalating acridine derivatives can induce p53 stabilization by a manner similar to CP-31398.

Curcumin 87-95 P53 Homo sapiens 141-144 16082197-4 2005 Recent findings suggest that p53 also undergoes ubiquitin-independent degradation by the 20S proteasomes and that this process is regulated by NAD(P)H quinone oxidoreductase 1 (NQO1) together with NADH.

Serine 61-67 P53 Homo sapiens 54-57 15843377-6 2005 These observations show that phosphorylation of serine 46 in p53 is sufficient for it to induce the PTEN (phosphatase and tensin homolog deleted on chromosome ten) tumor suppressor protein in preference to MDM2.

Glutathione 33-44 P53 Homo sapiens 24-27 15854392-8 2005 It was found that P53 protein translocated from nuclear to cytoplasm and could not phosphorate after the stimulation of cisplatin. Cisplatin 120-129 P53 Homo sapiens 18-21 15946545-2 2005 METHODS: Plasmid containing mutant p53-GFP was constructed by site-directed mutagenesis by which 5 amino scid residues in the nuclear localization signal (NLS) were replaced by alanine to produce mutant p53KRKKK-GFP. Alanine 177-184 P53 Homo sapiens 35-38 15854392-12 2005 CONCLUSIONS: p53 mutation induced by cisplatin/carboplatin might play an important role in the development of acquired multi-drug resistance of lung cancer chemotherapy. Cisplatin 37-46 P53 Homo sapiens 13-16 15583690-7 2005 Thus, the present study revealed that (a) the Arg allele is associated with p53 mutations, (b) the Pro allele is preferentially lost in OSCCs associated with cigarette smoking and AQ chewing, while the frequency of Arg allele loss is increased with alcohol drinking, and (c) haploinsufficiency of p53 is in itself likely to contribute to tumour progression in Taiwanese OSCCs. Arginine 46-49 P53 Homo sapiens 76-79 15580302-4 2005 Treatment of p53-positive cell lines U2OS and MCF-7 with the DNA damaging drug, doxorubicin, which increases p53 protein level, induced expression of Ipaf mRNA but similar treatment of MCF-7-mp53 (a clone of MCF-7 cells expressing mutant p53) and p53-negative K562 cells showed much less induction of Ipaf gene expression. Doxorubicin 80-91 P53 Homo sapiens 13-16 15580302-4 2005 Treatment of p53-positive cell lines U2OS and MCF-7 with the DNA damaging drug, doxorubicin, which increases p53 protein level, induced expression of Ipaf mRNA but similar treatment of MCF-7-mp53 (a clone of MCF-7 cells expressing mutant p53) and p53-negative K562 cells showed much less induction of Ipaf gene expression.

Doxorubicin 80-91 P53 Homo sapiens 109-112 15592521-10 2005 Strikingly, CYR61 overexpression impaired the accumulation of wild-type p53 following Taxol exposure, while inhibition of alphavbeta3 or ERK1/ERK2 MAPK signalings completely restored Taxol-induced upregulation of p53. Paclitaxel 86-91 P53 Homo sapiens 72-75 15592521-10 2005 Strikingly, CYR61 overexpression impaired the accumulation of wild-type p53 following Taxol exposure, while inhibition of alphavbeta3 or ERK1/ERK2 MAPK signalings completely restored Taxol-induced upregulation of p53. Paclitaxel 183-188 P53 Homo sapiens 213-216 15580302-5 2005 Expression analysis for Ipaf mRNA in doxorubicin-treated human tumor cell lines suggests that p53-dependent as well as p53-independent mechanisms are involved in the regulation of Ipaf gene expression in a cell-type-specific manner. Doxorubicin 37-48 P53 Homo sapiens 94-97 15580302-5 2005 Expression analysis for Ipaf mRNA in doxorubicin-treated human tumor cell lines suggests that p53-dependent as well as p53-independent mechanisms are involved in the regulation of Ipaf gene expression in a cell-type-specific manner. Doxorubicin 37-48 P53 Homo sapiens 119-122 15580310-4 2005 Here, we determined that 17beta-estradiol (E(2)) activated WOX1, p53 and ERK in COS7 fibroblasts, primary lung epithelial cells, and androgen receptor (AR)-negative prostate DU145 cells, but not in estrogen receptor (ER)-positive breast MCF7 cells. Estradiol 25-41 P53 Homo sapiens 65-68 15642743-1 2005 The proapoptotic activity of the transcription factor p53 critically depends on the phosphorylation of serine 46 (p53S46P). Serine 103-109 P53 Homo sapiens 54-57 15642743-3 2005 In this latter model, cell death was the result of a sequential process involving cell fusion, nuclear fusion (karyogamy), phosphorylation of serine 15 (p53S15P), later on serine 46 (p53S46P), and transcription of p53 target genes. Serine 142-148 P53 Homo sapiens 153-156 15583690-7 2005 Thus, the present study revealed that (a) the Arg allele is associated with p53 mutations, (b) the Pro allele is preferentially lost in OSCCs associated with cigarette smoking and AQ chewing, while the frequency of Arg allele loss is increased with alcohol drinking, and (c) haploinsufficiency of p53 is in itself likely to contribute to tumour progression in Taiwanese OSCCs.

Serine 50-56 P53 Homo sapiens 43-46 15574463-8 2005 After exposure to ionizing radiation, a dose-dependent defect in ataxia telangiectasia mutated (ATM)-serine 1981, p53-serine 15 and Chk2 phosphorylation, and p53 stabilization were noted, together with a failure to form Mre11 foci and enhanced radiation sensitivity. Serine 118-124 P53 Homo sapiens 114-117 15607904-4 2005 SK-N-BE human neuroblastoma cells express the three p53 family proteins and can be used for the study of their induction. Beryllium 5-7 P53 Homo sapiens 52-55 15533933-4 2005 Phosphorylation on Chk1(Ser-345), Chk2(Thr-68), and p53(Ser-15) following oxidative damage by IR involved both ATM and ATR. Serine 56-59 P53 Homo sapiens 52-55 15616590-0 2005 5-Lipoxygenase regulates senescence-like growth arrest by promoting ROS-dependent p53 activation. Reactive Oxygen Species 68-71 P53 Homo sapiens 82-85 15543231-8 2005 At the opposite, upon treatment with topoisomerase II inhibitors (doxorubicin or etoposide), the expression of TAp63 isoforms was clearly induced, independently of the TP53 status of cells. Doxorubicin 66-77 P53 Homo sapiens 168-172 15571721-5 2005 Electrophoretic mobility shift assay and intrinsic tryptophan fluorescence experiments also demonstrate that, although intrinsically disordered, polypeptides from the central region are able to mediate interactions with DNA and p53 with affinities in the low micromolar range. Tryptophan 51-61 P53 Homo sapiens 228-231 15711927-0 2005 Role of p53 and reactive oxygen species in apoptotic response to copper and zinc in epithelial breast cancer cells. Copper 65-71 P53 Homo sapiens 8-11 15603752-11 2005 Nevertheless, other regular participants in the DNA damage response, such as Gadd45a, Gadd153, p53, Hsp70, and ATM are still upregulated by high NaCl. Sodium Chloride 145-149 P53 Homo sapiens 95-98 16400524-8 2005 NAC treatment also restored cell cycle progression inhibited by rk-2 and down-regulated p53 and nuclear p21(Waf1/Cip1) expression induced by rk-2.These data suggest that rk-2 induces the BCE cell cycle arrest at G(0)-G(1) phase through inhibition of the cyclin D1/CDK4 complex caused by increase of ROS generation and nuclear cyclin-dependent kinase inhibitors. Acetylcysteine 0-3 P53 Homo sapiens 88-91 15711927-9 2005 Copper treatment did not result in accumulation of ROS in these cell lines with an inactive p53 even after exposure to 50 microM of copper for 6 h, indicating a key role for p53 in the ROS generation. Reactive Oxygen Species 185-188 P53 Homo sapiens 174-177 16082409-12 2005 Using specific phospho-serine antibodies, we identified phosphorylation of baculovirally expressed p53 protein at five distinct sites.

Cisplatin 99-108 P53 Homo sapiens 0-3 15608418-2 2005 Unlike the p53 gene, both encode for several isoforms which vary in their NH2 and COOH termini with variable and, in part, opposed biological functions. Carbonic Acid 82-86 P53 Homo sapiens 11-14 15608418-3 2005 The objective of the present study was to analyse the expression profiles of p53 family members in squamous cell carcinomas of the head and neck (HNSCC) and their alterations caused by exposure to the clinically active drug cisplatin. Cisplatin 224-233 P53 Homo sapiens 77-80 15711927-1 2005 Previous studies revealed that cells may differ in their response to metal stress depending on their p53 status; however, the sequence of events leading to copper-induced apoptosis is still unclear. Metals 69-74 P53 Homo sapiens 101-104 15816541-9 2005 In our analysis, the constitutive dephosphorylation at Ser 376 correlated with the nuclear accumulation of p53, but not with the transcriptional activity of the protein. Serine 55-58 P53 Homo sapiens 107-110 15711927-10 2005 Pretreatment of MCF7 cells with p53 inhibitor, pifithrin-alpha, resulted in decrease of copper and zinc induced ROS production to the control level, suppression of both Bax expression and AIF release. Copper 88-94 P53 Homo sapiens 32-35 15711927-2 2005 Exposure of copper (10 and 25 microM) and zinc (10 and 25 microM) caused activation of p53 in ER+/p53+ human epithelial breast cancer MCF7 cells and resulted in up-regulation of p21. Copper 12-18 P53 Homo sapiens 87-90 15711927-10 2005 Pretreatment of MCF7 cells with p53 inhibitor, pifithrin-alpha, resulted in decrease of copper and zinc induced ROS production to the control level, suppression of both Bax expression and AIF release. Reactive Oxygen Species 112-115 P53 Homo sapiens 32-35 15711927-2 2005 Exposure of copper (10 and 25 microM) and zinc (10 and 25 microM) caused activation of p53 in ER+/p53+ human epithelial breast cancer MCF7 cells and resulted in up-regulation of p21. Copper 12-18 P53 Homo sapiens 98-101 15711927-3 2005 Transactivation of p53 in MCF7 cells also led to increase in expression of Bax, proapototic Bcl-2 family member, triggering mitochondrial pore opening, and PIG3 (p53-induced gene 3 product), and also generation of intracellular reactive oxygen species (ROS). Reactive Oxygen Species 228-251 P53 Homo sapiens 19-22 15711927-11 2005 Therefore, the activation of p53 seems to play a crucial role in copper and zinc induced generation of ROS in epithelial breast cancer cells, and expression of downstream targets of p53, such as PIG3 and Bax, responsible for increased generation of the intracellular ROS, as well as disruption of mitochondrial integrity. Copper 65-71 P53 Homo sapiens 29-32 15711927-11 2005 Therefore, the activation of p53 seems to play a crucial role in copper and zinc induced generation of ROS in epithelial breast cancer cells, and expression of downstream targets of p53, such as PIG3 and Bax, responsible for increased generation of the intracellular ROS, as well as disruption of mitochondrial integrity. Reactive Oxygen Species 103-106 P53 Homo sapiens 29-32 15711927-11 2005 Therefore, the activation of p53 seems to play a crucial role in copper and zinc induced generation of ROS in epithelial breast cancer cells, and expression of downstream targets of p53, such as PIG3 and Bax, responsible for increased generation of the intracellular ROS, as well as disruption of mitochondrial integrity. Reactive Oxygen Species 267-270 P53 Homo sapiens 29-32 15711927-11 2005 Therefore, the activation of p53 seems to play a crucial role in copper and zinc induced generation of ROS in epithelial breast cancer cells, and expression of downstream targets of p53, such as PIG3 and Bax, responsible for increased generation of the intracellular ROS, as well as disruption of mitochondrial integrity. Reactive Oxygen Species 267-270 P53 Homo sapiens 182-185 15711927-3 2005 Transactivation of p53 in MCF7 cells also led to increase in expression of Bax, proapototic Bcl-2 family member, triggering mitochondrial pore opening, and PIG3 (p53-induced gene 3 product), and also generation of intracellular reactive oxygen species (ROS). Reactive Oxygen Species 253-256 P53 Homo sapiens 19-22 15711927-4 2005 The treatment of MCF7 cells with either copper or zinc for 4 h also caused decrease in mitochondrial membrane potential (Delta psi(m)), accompanied by an elevation in the ROS production and redistribution of p53 into mitochondria. Copper 40-46 P53 Homo sapiens 208-211 15365767-3 2005 In the work reported here we investigated the ability of docosahexaenoic acid (DHA) to potentiate the antineoplastic activity of 5-fluorouracil (5-FU) in p53-wildtype (LS-174 and Colo 320) and p53-mutant (HT-29 and Colo 205) human colon cancer cells. Fluorouracil 129-143 P53 Homo sapiens 154-157 16168113-9 2005 The sequence Dox-->Pacl-->48-h washout-->5-FU produced a synergistic and highly schedule-dependent interaction (combination index < 1), resulting in an induction of apoptosis in both experimental models regardless of hormonal, p53, bcl-2 or bax status. Doxorubicin 13-16 P53 Homo sapiens 239-242 16168113-9 2005 The sequence Dox-->Pacl-->48-h washout-->5-FU produced a synergistic and highly schedule-dependent interaction (combination index < 1), resulting in an induction of apoptosis in both experimental models regardless of hormonal, p53, bcl-2 or bax status.

Calcium 48-55 P53 Homo sapiens 0-3 15339849-3 2005 p53 deletions were associated with higher serum calcium (P = .0062) and creatinine (P = .013) levels, but there were no association with patient age, gender, beta2-microglobulin, C-reactive protein, hemoglobin, albumin or bone lytic lesions, or immunoglobulin isotype.

Fluorouracil 145-149 P53 Homo sapiens 154-157 15662138-0 2005 The tumor suppressor p33ING1b enhances taxol-induced apoptosis by p53-dependent pathway in human osteosarcoma U2OS cells. Paclitaxel 39-44 P53 Homo sapiens 66-69 16289503-5 2005 The TP53 Arg/Arg codon 72 genotype was detected in 21.9% of ICSCC and in 18.2% of CIN3 but only in 6% of CIN1-2 and in 5.2% of controls (P<0.05). Arginine 9-12 P53 Homo sapiens 4-8 15662138-4 2005 The results showed that p33ING1b markedly increased taxol-induced growth inhibition and apoptosis in p53+/+ U2OS cells, but not in p53-mutant MG63 cells. Paclitaxel 52-57 P53 Homo sapiens 101-104 15662138-6 2005 Taken together, our data demonstrate that p33ING1b enhances taxol-induced apoptosis through p53-dependent pathway in human osteosarcoma cells. Paclitaxel 60-65 P53 Homo sapiens 92-95 16122882-1 2005 BACKGROUND: The Arg/Arg genotype versus Arg/Pro or Pro/Pro at codon 72 of the p53 gene has been implicated in increasing susceptibility of the cervix to human papillomavirus (HPV) infection and thus altering cancer risk. Arginine 16-19 P53 Homo sapiens 78-81 16122882-1 2005 BACKGROUND: The Arg/Arg genotype versus Arg/Pro or Pro/Pro at codon 72 of the p53 gene has been implicated in increasing susceptibility of the cervix to human papillomavirus (HPV) infection and thus altering cancer risk. Arginine 20-23 P53 Homo sapiens 78-81 16122882-1 2005 BACKGROUND: The Arg/Arg genotype versus Arg/Pro or Pro/Pro at codon 72 of the p53 gene has been implicated in increasing susceptibility of the cervix to human papillomavirus (HPV) infection and thus altering cancer risk. Arginine 20-23 P53 Homo sapiens 78-81 16289503-5 2005 The TP53 Arg/Arg codon 72 genotype was detected in 21.9% of ICSCC and in 18.2% of CIN3 but only in 6% of CIN1-2 and in 5.2% of controls (P<0.05). Arginine 13-16 P53 Homo sapiens 4-8 16289503-8 2005 We conclude that TP53 Arg/Arg codon 72 genotype is a relevant risk factor for invasive squamous cell carcinoma of the conjunctiva and for CIN3 in the Ugandan population. Arginine 22-25 P53 Homo sapiens 17-21 16289503-8 2005 We conclude that TP53 Arg/Arg codon 72 genotype is a relevant risk factor for invasive squamous cell carcinoma of the conjunctiva and for CIN3 in the Ugandan population. Arginine 26-29 P53 Homo sapiens 17-21 15671536-6 2005 After treatment of Adriamycin with serial dose for 24 hours, we measured the uptake of 125I and did Western blot analysis to evaluate expression of p53 protein. Doxorubicin 19-29 P53 Homo sapiens 148-151 15619007-2 2005 Isogenic and isophenotypic human thyroid papillary carcinoma cell line variants for p53 differently expressed cycle genes after cisplatin treatment. Cisplatin 128-137 P53 Homo sapiens 84-87 15619007-4 2005 While cisplatin treatment increased their expression in p53 wild-type cells it decreased it in cells with inactivated p53 and had no or less effect on cells with mutated p53. Cisplatin 6-15 P53 Homo sapiens 56-59 15619007-4 2005 While cisplatin treatment increased their expression in p53 wild-type cells it decreased it in cells with inactivated p53 and had no or less effect on cells with mutated p53. Cisplatin 6-15 P53 Homo sapiens 118-121 15619007-4 2005 While cisplatin treatment increased their expression in p53 wild-type cells it decreased it in cells with inactivated p53 and had no or less effect on cells with mutated p53. Cisplatin 6-15 P53 Homo sapiens 118-121 15619007-5 2005 These results show that in a well-defined system, different alterations of p53 can lead to a different regulation of genes and hence to either resistance or sensitivity to cisplatin. Cisplatin 172-181 P53 Homo sapiens 75-78 15671536-11 2005 As Adriamycin dose increased, radioiodide uptake was significantly correlated with activated p53 as well as total p53 protein level. Doxorubicin 3-13 P53 Homo sapiens 93-96 15671536-11 2005 As Adriamycin dose increased, radioiodide uptake was significantly correlated with activated p53 as well as total p53 protein level. Doxorubicin 3-13 P53 Homo sapiens 114-117 15720258-5 2005 It is known that the tumor-suppressor proteins p53 and p73, and the oncoprotein c-Myc, which function as transcription factors, influence cellular sensitivity to cisplatin. Cisplatin 162-171 P53 Homo sapiens 47-50 16248785-1 2005 S100B interacts with the p53 protein in a calcium-dependent manner and down-regulates its function as a tumor suppressor.

Arginine 25-28 P53 Homo sapiens 71-74 15732191-14 2005 Using a formal meta-analysis of the published literature we show that carriers of the TP53 codon 72 Pro/Pro genotype have an increased cancer risk compared to Arg/Arg carriers (p<0.05). Arginine 159-162 P53 Homo sapiens 86-90 15732191-14 2005 Using a formal meta-analysis of the published literature we show that carriers of the TP53 codon 72 Pro/Pro genotype have an increased cancer risk compared to Arg/Arg carriers (p<0.05). Arginine 163-166 P53 Homo sapiens 86-90 15827887-6 2005 Hippocampal cultures pretreated with ZnCl2 before anoxia showed decreased immunoreactivity for p53 and BAX, connected with BCL-2 overexpression, whereas the cultures exposed to zinc chelating agent - TPEN or TPEN connected with anoxia showed significant increase of immunorectivity for p53 and BAX. zinc chloride 37-42 P53 Homo sapiens 286-289 15827887-7 2005 This strong immunoreactivity of proapototic proteins (p53 and BAX) in hippocampal cultures exposed to anoxia or/and TPEN correlated with previous ultrastructural evidences of anoxia- and TPEN-induced apoptosis, while the overexpression of anti-apoptotic protein (BCL-2 and BCL-X) in zinc-pretreated cultures evidenced the protective ability of this metal against apoptosis in model of anoxia in vitro. Metals 349-354 P53 Homo sapiens 54-57 15583825-15 2005 These findings strongly suggest that: a) TP53 is a novel molecular sensor of energy imbalance after the perturbation of endogenous fatty acid metabolism in breast cancer cells; b) TP53 function closely influences the decision between apoptosis and growth arrest following FAS blockade; and c) pharmacological inhibitors of FAS activity may be clinically useful against breast carcinomas exhibiting mutation or aberrant expression of TP53.

Tyrosine 144-152 P53 Homo sapiens 4-7 15583825-15 2005 These findings strongly suggest that: a) TP53 is a novel molecular sensor of energy imbalance after the perturbation of endogenous fatty acid metabolism in breast cancer cells; b) TP53 function closely influences the decision between apoptosis and growth arrest following FAS blockade; and c) pharmacological inhibitors of FAS activity may be clinically useful against breast carcinomas exhibiting mutation or aberrant expression of TP53. Fatty Acids 131-141 P53 Homo sapiens 41-45 15583825-15 2005 These findings strongly suggest that: a) TP53 is a novel molecular sensor of energy imbalance after the perturbation of endogenous fatty acid metabolism in breast cancer cells; b) TP53 function closely influences the decision between apoptosis and growth arrest following FAS blockade; and c) pharmacological inhibitors of FAS activity may be clinically useful against breast carcinomas exhibiting mutation or aberrant expression of TP53. Fatty Acids 131-141 P53 Homo sapiens 180-184 16302680-7 2005 In conclusion, our finding suggests the functional p53 codon 72 polymorphism may be associated with SLE susceptibility, suggesting individuals who carry the Pro allele may have a higher risk to SLE susceptibility than those with the Arg allele. Arginine 233-236 P53 Homo sapiens 51-54 15623478-1 2005 BACKGROUND: The predictive value of codon 72 arginine homozygosity at the p53 gene for human papilloma virus associated cervical cancer risk remains inconclusive. Arginine 45-53 P53 Homo sapiens 74-77 15623478-7 2005 The p53 codon 72 arginine homozygous genotype was significantly over represented in patients compared with controls. Arginine 17-25 P53 Homo sapiens 4-7 15623478-10 2005 CONCLUSION: p53 codon 72 arginine homozygotes appear to be at greater risk of developing squamous cell carcinoma of the uterine cervix. Arginine 25-33 P53 Homo sapiens 12-15 15657356-5 2005 Induction of apoptosis by EGCG could be corroborated to the increased expression of tumor suppressor protein p53 and its phosphorylation at Ser 15 residue. Serine 140-143 P53 Homo sapiens 109-112 15860933-0 2005 Overexpression of protein kinase Cdelta enhances cisplatin-induced cytotoxicity correlated with p53 in gastric cancer cell line. Cisplatin 49-58 P53 Homo sapiens 96-99 16127286-7 2005 This outcome is consistent with the clinical observation that the efficacy of topotecan in the treatment of relapsed ovarian carcinoma patients is dependent on platinum sensitivity, because platinum-sensitive tumors are expected to carry wild-type p53. Platinum 160-168 P53 Homo sapiens 248-251 16127286-7 2005 This outcome is consistent with the clinical observation that the efficacy of topotecan in the treatment of relapsed ovarian carcinoma patients is dependent on platinum sensitivity, because platinum-sensitive tumors are expected to carry wild-type p53. Platinum 190-198 P53 Homo sapiens 248-251 16127286-8 2005 Although untreated mutant p53 tumors may be responsive to first-line paclitaxel-containing therapy, it is likely that loss of p53 leads to genomic instability resulting in rapid progression to drug resistance. Paclitaxel 69-79 P53 Homo sapiens 26-29 16391388-0 2005 Expression profiling of p53-target genes in copper-mediated neuronal apoptosis. Copper 44-50 P53 Homo sapiens 24-27 16391388-2 2005 Our previous work in cultured human NTERA-2-N neurons showed that copper-induced neuronal apoptosis is dependent on the induction and nuclear translocation of the tumor suppressor protein, p53. Copper 66-72 P53 Homo sapiens 189-192 16391388-3 2005 Because p53 acts as a DNA-binding transcription factor, this work used an oligonucleotide array to identify p53 target genes that are differentially regulated in copper-loaded neurons. Copper 162-168 P53 Homo sapiens 8-11 16391388-3 2005 Because p53 acts as a DNA-binding transcription factor, this work used an oligonucleotide array to identify p53 target genes that are differentially regulated in copper-loaded neurons. Copper 162-168 P53 Homo sapiens 108-111 16391388-4 2005 Arrays representing 145 human genes expressed downstream of p53 were hybridized with labeled mRNA from control and copper-treated neurons. Copper 115-121 P53 Homo sapiens 60-63 15860933-8 2005 Moreover, overexpression of both wild-type p53 and exogenous PKCdelta in MKN28 increased cisplatin-induced cell death in MKN28. Cisplatin 89-98 P53 Homo sapiens 43-46 15860933-9 2005 CONCLUSION: These results suggest that PKCdelta, in cooperation with p53, possibly regulates cisplatin-induced caspase-3-mediated cell death in gastric cancer. Cisplatin 93-102 P53 Homo sapiens 69-72 15860933-2 2005 Cisplatin is one of the DNA-damaging agents and several factors including p53 are related to the sensitivity to cisplatin in cancer. Cisplatin 0-9 P53 Homo sapiens 74-77 15860933-2 2005 Cisplatin is one of the DNA-damaging agents and several factors including p53 are related to the sensitivity to cisplatin in cancer. Cisplatin 112-121 P53 Homo sapiens 74-77 15860933-4 2005 In our present study, we examined whether overexpression of PKCdelta and p53 increases the sensitivity of the human gastric cancer cell line, MKN28, which has a mutation of p53 gene, to cisplatin. Cisplatin 186-195 P53 Homo sapiens 73-76 15844595-1 2005 OBJECTIVE: To investigate the codon-72 polymorphism of the tumor suppressor gene p53, codon-72 encodes arginine (Arg) or proline (Pro) for a genetic predisposition,to keloid or hypertrophic scar. Arginine 103-111 P53 Homo sapiens 81-84 15389812-3 2005 RESULTS: CDDP and DACH-Ac-Pt were equiactive against mutant p53 and androgen-independent DU-145 or PC-3 tumor cells. cddp 9-13 P53 Homo sapiens 60-63 15389812-4 2005 In wild-type p53 cells, CDDP was threefold more potent against androgen-dependent LNCaP than isogenic androgen-independent LNCaP-LN3 cells. cddp 24-28 P53 Homo sapiens 13-16 15389812-6 2005 The greater potency of DACH-Ac-Pt than CDDP in wild-type p53 cells was not due to increased cellular drug uptake or increased adduct levels, but correlated with a lower tolerance to DNA damage. cddp 39-43 P53 Homo sapiens 57-60 15456759-9 2004 Small interfering RNA was used to show that hPTIP is required for ATM-mediated phosphorylation of p53 at Ser(15) and for IR-induced up-regulation of the cyclin-dependent kinase inhibitor p21. Serine 105-108 P53 Homo sapiens 98-101 15844595-1 2005 OBJECTIVE: To investigate the codon-72 polymorphism of the tumor suppressor gene p53, codon-72 encodes arginine (Arg) or proline (Pro) for a genetic predisposition,to keloid or hypertrophic scar. Arginine 113-116 P53 Homo sapiens 81-84 15665582-3 2004 UV-damage and the damage caused by certain chemotherapeutics including cisplatin and nitrogen mustards are known to be repaired by the nucleotide excision repair (NER) pathway which is reportedly regulated by p53 and its downstream genes. Cisplatin 71-80 P53 Homo sapiens 209-212 15665582-3 2004 UV-damage and the damage caused by certain chemotherapeutics including cisplatin and nitrogen mustards are known to be repaired by the nucleotide excision repair (NER) pathway which is reportedly regulated by p53 and its downstream genes. Nitrogen 85-93 P53 Homo sapiens 209-212 15531296-9 2004 Western blotting showed that the synthesis of intracellular p53 and bax protein was gradually up-regulated in the virus-loading period of 72 h. Naloxone had an apparent additive rather than antagonistic effect on the morphine-associated enhancement of bax expression. Morphine 217-225 P53 Homo sapiens 60-63 15471885-7 2004 We conclude that p53 phosphorylation on six major serine sites is not required for activation of p53 target genes or biological responses in vivo. Serine 50-56 P53 Homo sapiens 17-20 15595848-9 2004 Thus, the mutational "hot spot" at codon 273 in P53 may reflect either sequence-specific reactivity of BPDE and/or inefficient repair of BPDE-DNA adducts positioned at this site. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 137-141 P53 Homo sapiens 48-51 15595848-0 2004 Mutagenic potential of benzo[a]pyrene-derived DNA adducts positioned in codon 273 of the human P53 gene. pyrene 31-37 P53 Homo sapiens 95-98 15595848-2 2004 We incorporated a single (+)- or (-)-trans-anti-benzo[a]pyrene diol epoxide (BPDE) DNA adduct at the second position of codon 273 of the human P53 gene and explored the mutagenic potential of this lesion in mammalian cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 77-81 P53 Homo sapiens 143-146 15595848-9 2004 Thus, the mutational "hot spot" at codon 273 in P53 may reflect either sequence-specific reactivity of BPDE and/or inefficient repair of BPDE-DNA adducts positioned at this site. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 103-107 P53 Homo sapiens 48-51 15489221-4 2004 Using several ATM-proficient and ATM-deficient cell lines, we have observed ATM-dependent nuclear accumulation of p53 and ATM-dependent phosphorylation of p53 on seven serine residues. Serine 168-174 P53 Homo sapiens 155-158 15471885-0 2004 Phosphorylation of p53 on key serines is dispensable for transcriptional activation and apoptosis. Serine 30-37 P53 Homo sapiens 19-22 15471885-4 2004 We therefore investigated the role of p53 phosphorylation on six key serine residues (Ser(6), Ser(15), Ser(20), Ser(37), Ser(46), and Ser(392)) for p53 activation using nutlin-3, a recently developed small molecule MDM2 antagonist.

Doxorubicin 101-112 P53 Homo sapiens 66-69 15489221-10 2004 In contrast, preincubation of cells with the hydroxyl radical scavenger, N-acetylcysteine, significantly attenuated the doxorubicin-mediated phosphorylation and accumulation of p53, p53-DNA binding, and the phosphorylation of H2AX, Nbs1, SMC1, Chk1, and Chk2, suggesting that hydroxyl radicals contribute to the doxorubicin-induced activation of ATM-dependent pathways.

Doxorubicin 147-158 P53 Homo sapiens 241-244 15601469-12 2004 CONCLUSIONS: p21 induction may significantly contribute to the response of colon adenocarcinomas cells to DOX treatment; and small molecules that can exploit p53-independent pathways for p21 induction, such as TPL, may find a place in chemotherapeutic protocols for the clinical management of colorectal cancer, where p53 function is often lost, due to genetic or epigenetic defects or to post-transcriptional inactivating mechanisms.

Doxorubicin 89-92 P53 Homo sapiens 34-37 15601469-5 2004 METHODS: The relationship between p53 and p21 protein levels and the cytotoxic effect of DOX was investigated, by MTT assay and western blot analysis, in HCT116 (p53-positive) and HT29 (p53-negative) colon cancer cells. Doxorubicin 89-92 P53 Homo sapiens 162-165 15534883-3 2004 p53 is a tumor suppressor gene, and X-ray cross-complementing group 1 (XRCC1) is involved in the base-excision repair of ROS-induced DNA damage.

Doxorubicin 89-92 P53 Homo sapiens 162-165 15469940-8 2004 Downstream target genes of p53, such as p21Cip/WAF1 and PTEN, were inhibited by Aurora-A in a Ser-215 phosphorylation-dependent manner (i.e. phosphomimic p53-S215D lost and non-phosphorylatable p53-S215A retained normal p53 function). Serine 94-97 P53 Homo sapiens 27-30 15604280-3 2004 Whereas irinotecan-induced up-regulation of the proapoptotic proteins PUMA and Noxa requires p53, we find that irinotecan inhibits Janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 and 5 (STAT3/5) signaling in both p53-proficient and p53-deficient tumor cells. Irinotecan 111-121 P53 Homo sapiens 238-241 15604280-4 2004 We show that irinotecan inhibits JAK2-STAT3/5-dependent expression of survival proteins (Bcl-x(L) and XIAP) and cooperates with Apo2 ligand/tumor necrosis factor-related apoptosis-inducing ligand (Apo2L/TRAIL) to facilitate p53-independent apoptosis of colon cancer cells. Irinotecan 13-23 P53 Homo sapiens 224-227 15604280-5 2004 Whereas xenografts of p53-deficient colon cancer cells are relatively resistant to irinotecan compared with their p53-proficient counterparts, combined treatment with irinotecan and Apo2L/TRAIL eliminates hepatic metastases of both p53-proficient and p53-deficient cancer cells in vivo and significantly improves the survival of animals relative to treatment with either agent alone.

Irinotecan 167-177 P53 Homo sapiens 114-117 15604280-6 2004 Although the synergy between chemotherapy and Apo2L/TRAIL has been ascribed to p53, our data demonstrate that irinotecan enhances Apo2L/TRAIL-induced apoptosis of tumor cells via a distinct p53-independent mechanism involving inhibition of JAK2-STAT3/5 signaling. Irinotecan 110-120 P53 Homo sapiens 190-193 15604280-7 2004 These findings identify a novel p53-independent channel of cross-talk between topoisomerase I inhibitors and Apo2L/TRAIL and suggest that the addition of Apo2L/TRAIL can improve the therapeutic index of irinotecan against both p53-proficient and p53-deficient colorectal cancers, including those that have metastasized to the liver.

Cisplatin 203-212 P53 Homo sapiens 297-300 15573749-5 2004 Both TK6 and WTK1 cells showed effective post-damage repair capacity in incubation time of 0.5 h to 1 h. The background level of P53 protein in WTK1 was higher than that in TK6, but the level of P53 protein in H2O2-treated TK6 increased significantly higher than that in H2O2-treated WTK1. Hydrogen Peroxide 271-275 P53 Homo sapiens 129-132 15509798-7 2004 Small-molecule manipulation of p53 DNA binding activity has been an elusive goal, but here we show that NAD(+) binds to p53 tetramers, induces a conformational change, and modulates p53 DNA binding specificity in vitro. NAD 104-110 P53 Homo sapiens 120-123 15509798-9 2004 These effects are likely due to a direct effect of NAD(+) on p53, as a molecule structurally related to part of NAD(+), TDP, also inhibits p53 DNA binding, and the TDP precursor, thiamine (vitamin B(1)), inhibits intracellular p53 activity. NAD 51-57 P53 Homo sapiens 61-64 15509798-9 2004 These effects are likely due to a direct effect of NAD(+) on p53, as a molecule structurally related to part of NAD(+), TDP, also inhibits p53 DNA binding, and the TDP precursor, thiamine (vitamin B(1)), inhibits intracellular p53 activity.

UNII-PYZ33YLR8A 59-64 P53 Homo sapiens 37-40 15381086-1 2004 Phosphorylation of p53 at Ser15, Thr18, and Ser20 has been thought to be important for p53 stabilization in response to ionizing radiation. UNII-PYZ33YLR8A 33-38 P53 Homo sapiens 19-22 15381086-1 2004 Phosphorylation of p53 at Ser15, Thr18, and Ser20 has been thought to be important for p53 stabilization in response to ionizing radiation. UNII-PYZ33YLR8A 33-38 P53 Homo sapiens 87-90 15381086-2 2004 In the present study, we examined the X-ray-induced stabilization of Ala-substituted p53 protein at Ser15, Thr18, and Ser20, whose gene expression was controlled under an ecdyson-inducible promoter.

UNII-PYZ33YLR8A 107-112 P53 Homo sapiens 85-88 15381086-3 2004 We found that all single-, double-, or triple-Ala-substituted p53 at Ser15, Yhr18, and Ser20 were accumulated in the nucleus similarly to wild-type p53 after X-irradiation. Alanine 46-49 P53 Homo sapiens 62-65 15381086-4 2004 These results indicate that the phosphorylation of p53 at Ser15, Thr18, and Ser20 is not necessarily needed for p53 stabilization in response to ionizing radiation. UNII-PYZ33YLR8A 65-70 P53 Homo sapiens 51-54 15464845-4 2004 B1R is able to hyperphosphorylate p53 in several residues in the N-terminal transactivation domain, including Ser15 and Thr18. UNII-PYZ33YLR8A 120-125 P53 Homo sapiens 34-37 15464845-7 2004 The over-expressed B1R protein induces the degradation of p53 in a concentration-dependent manner and is lost when Ser15 and Th18 are changed to alanine or when the B1R kinase is inactivated by introducing the K149Q substitution. Alanine 145-152 P53 Homo sapiens 58-61 15361831-5 2004 In BaF3 cells and transiently transfected MCF7 breast cancer cells, elevation of total and phospho-Ser15-p53 in response to Adriamycin is blocked by Survivin and enhanced by Survivin disruption. Doxorubicin 124-134 P53 Homo sapiens 105-108 15361831-6 2004 Furthermore, in Adriamycin-treated MCF7 cells, ectopic Survivin decreased p53 mRNA and increased mRNA and protein of the p53 homologues DeltaNp63 and TAp73 and mRNA for DeltaNp73, suggesting that Survivin may differentially regulate p53 family transcription. Doxorubicin 16-26 P53 Homo sapiens 74-77 15361831-6 2004 Furthermore, in Adriamycin-treated MCF7 cells, ectopic Survivin decreased p53 mRNA and increased mRNA and protein of the p53 homologues DeltaNp63 and TAp73 and mRNA for DeltaNp73, suggesting that Survivin may differentially regulate p53 family transcription. Doxorubicin 16-26 P53 Homo sapiens 121-124 15361831-6 2004 Furthermore, in Adriamycin-treated MCF7 cells, ectopic Survivin decreased p53 mRNA and increased mRNA and protein of the p53 homologues DeltaNp63 and TAp73 and mRNA for DeltaNp73, suggesting that Survivin may differentially regulate p53 family transcription.

Cisplatin 145-154 P53 Homo sapiens 46-49 15452549-11 2004 Our observations show that a marked in vivo response to cisplatin can occur via p53-dependent apoptosis or independently of p53 status in human ovarian xenografts. Cisplatin 56-65 P53 Homo sapiens 80-83 15452549-11 2004 Our observations show that a marked in vivo response to cisplatin can occur via p53-dependent apoptosis or independently of p53 status in human ovarian xenografts. Cisplatin 56-65 P53 Homo sapiens 124-127 15486204-0 2004 Differential recognition by the tumor suppressor protein p53 of DNA modified by the novel antitumor trinuclear platinum drug BBR3464 and cisplatin.

Cisplatin 137-146 P53 Homo sapiens 57-60 15486204-3 2004 In contrast, on average, cells with mutant p53 are more resistant to the effect of cisplatin. Cisplatin 83-92 P53 Homo sapiens 43-46 15486204-4 2004 It has been hypothesized that the sensitivity or resistance of tumor cells to cisplatin might be also associated with cell cycle control and repair processes that involve p53. Cisplatin 78-87 P53 Homo sapiens 171-174 15486204-5 2004 DNA is a major pharmacological target of platinum compounds and DNA binding activity of the p53 protein is crucial for its tumor suppressor function. Platinum 41-49 P53 Homo sapiens 92-95 15486204-6 2004 This study, using gel-mobility-shift assays, was undertaken to examine the interactions of active and latent p53 protein with DNA fragments and oligodeoxyribonucleotide duplexes modified by BBR3464 in a cell free medium and to compare these results with those describing the interactions of these proteins with DNA modified by cisplatin. Cisplatin 327-336 P53 Homo sapiens 109-112 15486204-7 2004 The results indicate that structurally different DNA adducts of BBR3464 and cisplatin exhibit a different efficiency to affect the binding affinity of the modified DNA to p53 protein. Cisplatin 76-85 P53 Homo sapiens 171-174 15486204-8 2004 It has been suggested that different structural perturbations induced in DNA by the adducts of BBR3464 and cisplatin produce a differential response to p53 protein activation and recognition and that a "molecular approach" to control of downstream effects such as protein recognition and pathways of apoptosis induction may consist in design of structurally unique DNA adducts as cell signals. Cisplatin 107-116 P53 Homo sapiens 152-155 15280358-6 2004 We mapped the TBP-interacting region in the C terminus of ZNF76 to a glutamic acid-rich domain, which acts in a dominant negative manner to enhance p53-mediated transactivation in reporter assays. Glutamic Acid 69-82 P53 Homo sapiens 148-151 15456252-0 2004 Identification and characterization of small molecule inhibitors of the calcium-dependent S100B-p53 tumor suppressor interaction. Calcium 72-79 P53 Homo sapiens 96-99 15467449-6 2004 Together, these findings suggest that p21(Cip1/WAF1) partially protects p53-null human leukemia cells from paclitaxel-mediated lethality, and raise the possibility that p21(Cip1/WAF1)-associated perturbations in signal transduction pathways as well as Bcl-2 phosphorylation status may play a role in this phenomenon. Paclitaxel 107-117 P53 Homo sapiens 72-75 15361841-1 2004 A mutant version of p53 (p53-121F), in which phenylalanine replaces the 121st serine residue, can induce apoptosis more effectively than wild-type p53 (wt-p53).

Serine 78-84 P53 Homo sapiens 25-28 15473923-1 2004 BACKGROUND & OBJECTIVE: P53 gene is a tumor suppressor gene,and its mutation in human tumor cells is frequently observed. Adenosine Monophosphate 12-15 P53 Homo sapiens 28-31 15492278-8 2004 Western blot analysis confirmed that methionine stress caused the following: (a) a marked increase of GADD45alpha and gamma in the wt-p53 cell lines SWB61 and 40; (b) an increase in GADD34 and p21 protein in all of the methionine-dependent lines; and (c) the induction of MDA7 and phospho-p38 in DAOY and SWB39, consistent with marked transcriptional activation of the former under methionine stress. Methionine 37-47 P53 Homo sapiens 134-137 15373832-4 2004 In the absence of antibody, reduced p53 preferentially bound scDNA lacking p53CON in the presence of 3 kb linear plasmid DNAs or 20 mer oligonucleotides, both containing and lacking the p53CON. Oligonucleotides 136-152 P53 Homo sapiens 36-39 15390206-0 2004 Mutation of p53 in head and neck squamous cell carcinoma correlates with Bcl-2 expression and increased susceptibility to cisplatin-induced apoptosis. Cisplatin 122-131 P53 Homo sapiens 12-15 15390206-11 2004 Further investigation showed that SCCHN cells expressing predominantly mutant p53 and decreased Bcl-2 were more susceptible to cisplatin-induced apoptosis than vector-transfected controls (p < .0001). Cisplatin 127-136 P53 Homo sapiens 78-81 15472230-0 2004 Wild-type p53 protein is up-regulated upon cyclic adenosine monophosphate-induced differentiation of human endometrial stromal cells. Cyclic AMP 43-73 P53 Homo sapiens 10-13 15310764-6 2004 Moreover, NPM inhibits hypoxia-induced p53 phosphorylation at Ser-15 and interacts with p53 in hypoxic cells. Serine 62-65 P53 Homo sapiens 39-42 15472230-3 2004 We now report a massive and sustained up-regulation of p53 tumor suppressor protein during cAMP-induced decidualization of cultured endometrial stromal cells. Cyclic AMP 91-95 P53 Homo sapiens 55-58 15475475-6 2004 Paclitaxel activated p53 protein at low concentrations but exhibited G2/M cell cycle blocking activity at higher concentrations where microtubules were stabilized. Paclitaxel 0-10 P53 Homo sapiens 21-24 15472230-7 2004 In cAMP-treated decidualized cells, p53 accumulation was associated with decreased nuclear Mdm2 and cytoplasmic PKB/Akt levels. Cyclic AMP 3-7 P53 Homo sapiens 36-39 15258567-3 2004 We report here that forced expression of p14ARF enhances phosphorylation of p53 serine 15 (p53S15) in NIH3T3, IMR90 and MCF7 cells. Serine 80-86 P53 Homo sapiens 76-79 15364135-2 2004 p53 Overexpression has been associated with resistance to cisplatin-based chemotherapy in patients (pts) with NSCLC. Cisplatin 58-67 P53 Homo sapiens 0-3 15258255-11 2004 Taken together, our results show that exposure to C-1305 is accompanied by the formation of low levels of potent cleavable complexes that are selectively toxic toward tumor cells with defective p53 function. Carbon 50-51 P53 Homo sapiens 194-197 15486197-7 2004 In addition, paclitaxel, at cytostatic concentrations, early initiates an apoptotic signaling pathway associated with increases in the mitochondrial reducing potential, mitochondrial membrane potential, p53 expression, and Bax/Bcl-2 ratio. Paclitaxel 13-23 P53 Homo sapiens 203-206 15375518-0 2004 Radiosensitization of a human soft tissue sarcoma cell line US8-93 (mt-p53) with the oxidizer sodium peroxodisulfate. sodium persulfate 94-116 P53 Homo sapiens 71-74 15371598-5 2004 Assays with phage-displayed Nef from HIV(NL4-3) were used to identify a series of guanidine alkaloid-based inhibitors of Nef interactions with p53, actin, and p56(lck). guanidine alkaloid 82-100 P53 Homo sapiens 143-146 15802048-5 2004 Here we have used (1)H MRS to characterize the choline phospholipid metabolite levels of p53(+/ +) and p53(-/-) cells, and demonstrated that loss of p53 function results in increased phosphocholine and total choline. Phospholipids 55-67 P53 Homo sapiens 89-92 15802048-5 2004 Here we have used (1)H MRS to characterize the choline phospholipid metabolite levels of p53(+/ +) and p53(-/-) cells, and demonstrated that loss of p53 function results in increased phosphocholine and total choline. Phospholipids 55-67 P53 Homo sapiens 103-106 15802048-5 2004 Here we have used (1)H MRS to characterize the choline phospholipid metabolite levels of p53(+/ +) and p53(-/-) cells, and demonstrated that loss of p53 function results in increased phosphocholine and total choline. Phospholipids 55-67 P53 Homo sapiens 103-106 15802048-6 2004 These data suggest that the increased malignancy of cancer cells resulting from loss of p53 may be mediated, in part, through the choline phospholipid pathway. Phospholipids 138-150 P53 Homo sapiens 88-91 15334064-4 2004 Doxorubicin treatment activated p53, downregulated survivin and survivin-DeltaEx3 but upregulated survivin-2B in EU-3, an acute lymphocytic leukemia (ALL) cell line with wild-type (wt)-p53 phenotype. Doxorubicin 0-11 P53 Homo sapiens 32-35 15334064-4 2004 Doxorubicin treatment activated p53, downregulated survivin and survivin-DeltaEx3 but upregulated survivin-2B in EU-3, an acute lymphocytic leukemia (ALL) cell line with wild-type (wt)-p53 phenotype. Doxorubicin 0-11 P53 Homo sapiens 185-188 15269203-10 2004 In addition, it was shown that NBS1, SMC1, and p53 were phosphorylated in an ATM-dependent manner, and p53 phosphorylation on serine 20 is dependent on CHK2 after irofulven treatment. Serine 126-132 P53 Homo sapiens 47-50 15269203-10 2004 In addition, it was shown that NBS1, SMC1, and p53 were phosphorylated in an ATM-dependent manner, and p53 phosphorylation on serine 20 is dependent on CHK2 after irofulven treatment. Serine 126-132 P53 Homo sapiens 103-106 15374966-0 2004 Retinoic acid increases the expression of p53 and proapoptotic caspases and sensitizes keratinocytes to apoptosis: a possible explanation for tumor preventive action of retinoids. Tretinoin 0-13 P53 Homo sapiens 42-45 15374966-8 2004 Inhibition of p53 and caspases with alpha-pifithrin and z-Val-Ala-Asp-fluoromethyl ketone, respectively, blocked UVB- and doxorubicin-induced apoptosis in ATRA-treated KCs. Tretinoin 155-159 P53 Homo sapiens 14-17 15374966-9 2004 Analogous to the observed ATRA effects in monolayer cultures, in vitro-generated organotypic skin cultures reacted with up-regulation of p53 and proapoptotic caspases and displayed increased sensitivity to UVB-induced apoptosis. Tretinoin 26-30 P53 Homo sapiens 137-140 15374966-6 2004 Analysis by real-time PCR and Western blot revealed that ATRA treatment strongly increased the mRNA and protein expression of p53 and caspase-3, -6, -7, and -9, which are key regulators of apoptosis. Tretinoin 57-61 P53 Homo sapiens 126-129 15374966-7 2004 UVB irradiation of ATRA-treated cells but not of control cells led to the accumulation of p53 protein and of its target gene Noxa. Tretinoin 19-23 P53 Homo sapiens 90-93 15374978-8 2004 Conversely, concurrent treatment with SN-38 and UCN-01 resulted in S-phase checkpoint override, an amplified DNA damage response including increased phosphorylation of the DNA double-strand breakage marker H2AX and augmentation of clonogenic inhibition, which was independent of p53. Irinotecan 38-43 P53 Homo sapiens 279-282 15374966-8 2004 Inhibition of p53 and caspases with alpha-pifithrin and z-Val-Ala-Asp-fluoromethyl ketone, respectively, blocked UVB- and doxorubicin-induced apoptosis in ATRA-treated KCs. Doxorubicin 122-133 P53 Homo sapiens 14-17 15155458-7 2004 Phosphorylation of p53 at serines 15 and 392 is critical for complex formation. Serine 26-33 P53 Homo sapiens 19-22 15312749-5 2004 We observed two peaks of p53 activity during continuous treatment of 17-[beta]-estradiol (E2) for 72h. Estradiol 69-88 P53 Homo sapiens 25-28 15363194-1 2004 BACKGROUND & OBJECTIVE: Tumor suppressor gene p53 and oncogene C-erbB-2 are confirmed to have close relation with endometrioid adenocarcinoma (EC), few documents have been reported about their correlation. Adenosine Monophosphate 12-15 P53 Homo sapiens 50-53 15517885-3 2004 The growth-inhibitory effects of resveratrol are mediated through cell-cycle arrest; upregulation of p21Cip1/WAF1, p53 and Bax; down-regulation of survivin, cyclin D1, cyclin E, Bcl-2, Bcl-xL and clAPs; and activation of caspases. Resveratrol 33-44 P53 Homo sapiens 115-118 15131588-1 2004 A common arginine to proline polymorphism is harboured at codon 72 of the human p53 gene. Arginine 9-17 P53 Homo sapiens 80-83 15131591-3 2004 Restoration of functional p53 sensitized glioma cells expressing mutant p53 to TNF-alpha by accumulation of O2-*. Superoxides 108-110 P53 Homo sapiens 26-29 15326376-4 2004 We here show that inhibition of Chk1 but not of Chk2 in p21(-/-) and p53(-/-) cells caused a greater abrogation of G(2) block induced by ionizing radiation and cis-diamine-dichloroplatinum treatments and a greater sensitization to the same treatments than in the parental cell line with p53 and p21 wild type proteins. cis-diamine 160-171 P53 Homo sapiens 69-72 15131591-3 2004 Restoration of functional p53 sensitized glioma cells expressing mutant p53 to TNF-alpha by accumulation of O2-*. Superoxides 108-110 P53 Homo sapiens 72-75 15131591-6 2004 Two separate signaling cascades, p53-mediated ROS-dependent and -independent pathways, both of which are initiated by caspase-8 activation, thus contribute to ceramide formation in TNF-alpha-induced apoptosis of human glioma cells. Reactive Oxygen Species 46-49 P53 Homo sapiens 33-36 15254427-0 2004 p53-Dependent activation of a molecular beacon in tumor cells following exposure to doxorubicin chemotherapy. Doxorubicin 84-95 P53 Homo sapiens 0-3 15254427-3 2004 Strong nuclear signal was observed following treatment of wild-type p53-expressing human H460 lung cancer cells for 8 hours with the chemotherapeutic agent doxorubicin (adriamycin). Doxorubicin 156-167 P53 Homo sapiens 68-71 15254427-3 2004 Strong nuclear signal was observed following treatment of wild-type p53-expressing human H460 lung cancer cells for 8 hours with the chemotherapeutic agent doxorubicin (adriamycin). Doxorubicin 169-179 P53 Homo sapiens 68-71 15254427-6 2004 Increased signal from the phosphorothioate-modified p21-beacon in doxorubicin-treated cells likely resulted from sequence-specific hybridization as well as sequence-independent cleavage that may occur due to p53-dependent activation of endonucleases during apoptosis. Doxorubicin 66-77 P53 Homo sapiens 208-211 15342409-7 2004 HCT116 p53+/+ cells exhibit a more rapid removal of 8-oxoG from DNA than p53-/- cells exposed to the same levels of reactive oxygen species (ROS) stress. Reactive Oxygen Species 116-139 P53 Homo sapiens 7-10 15342409-0 2004 Role of p53 in sensing oxidative DNA damage in response to reactive oxygen species-generating agents. Reactive Oxygen Species 59-82 P53 Homo sapiens 8-11 15342409-7 2004 HCT116 p53+/+ cells exhibit a more rapid removal of 8-oxoG from DNA than p53-/- cells exposed to the same levels of reactive oxygen species (ROS) stress. Reactive Oxygen Species 141-144 P53 Homo sapiens 7-10 15342409-8 2004 Together, these results suggest that p53 participates in sensing oxidative DNA damage and modulates BER function in response to persistent ROS stress. Reactive Oxygen Species 139-142 P53 Homo sapiens 37-40 15342418-1 2004 We have demonstrated previously that interferon (IFN)-gamma sensitizes human colon carcinoma cell lines to the cytotoxic effects of 5-fluorouracil combined with leucovorin and to the thymidylate synthase inhibitor, ZD9331, dependent on thymineless stress-induced DNA damage, independent of p53. Fluorouracil 132-146 P53 Homo sapiens 290-293 15355354-0 2004 Structured DNA promotes phosphorylation of p53 by DNA-dependent protein kinase at serine 9 and threonine 18. Serine 82-88 P53 Homo sapiens 43-46 15467443-6 2004 This may be explained by the status of p53 serine 20 phosphorylation.

Serine 27-33 P53 Homo sapiens 40-43 15763944-7 2004 Moreover, Ang-1 inhibits DOX-induced up-regulation of p53 through PI3K/Akt. Doxorubicin 25-28 P53 Homo sapiens 54-57 15763945-10 2004 Doxil minimally affected the expression levels of p53, whereas other anthracyclines induced p53 protein levels to a significant level, resulting in endothelial cell apoptosis.

Curcumin 0-8 P53 Homo sapiens 34-37 15090465-5 2004 In compounds other than curcumin this same electrophilic moiety is associated with inactivation of the tumor suppressor, p53. Curcumin 24-32 P53 Homo sapiens 121-124 15090465-7 2004 It disrupts the conformation of the p53 protein required for its serine phosphorylation, its binding to DNA, its transactivation of p53-responsive genes and p53-mediated cell cycle arrest.

Serine 65-71 P53 Homo sapiens 132-135 15489061-9 2004 Our results indicate that similar mechanisms involving p21(WAF-1) and probably p53 are at work in BJ and hTERT-BJ1 HDFs under H2O2-induced SIPS, suggesting that generalized DNA damage rather than telomere length/telomerase plays a crucial role in H2O2induced SIPS. Hydrogen Peroxide 126-130 P53 Homo sapiens 79-82 15289875-4 2004 CDDP treatment caused steady induction of p53 protein in both cancer cell types, although it was more dramatic in CDDP-resistant HEp-2 cells, which was correlated well with p53 Ser15 phosphorylation, but not with the expression level of HPV type 18 E6 oncoprotein in these cells. Cisplatin 0-4 P53 Homo sapiens 42-45 15289867-10 2004 Additionally, flavone induced apoptosis in primary colon carcinoma cells COLO205-X with appearance of DNA ladders, caspase 3 protein procession, PARP protein cleavage, and an increase in p21 (not p53) protein. flavone 14-21 P53 Homo sapiens 196-199 15523893-6 2004 In this study, p53 protein immunoreactivity was investigated in paraffin sections of primary nasopharyngeal tumors and metastatic cervical lymph nodes and association with clinical and histopathological characteristics was evaluated.

Cisplatin 0-4 P53 Homo sapiens 173-176 15289875-4 2004 CDDP treatment caused steady induction of p53 protein in both cancer cell types, although it was more dramatic in CDDP-resistant HEp-2 cells, which was correlated well with p53 Ser15 phosphorylation, but not with the expression level of HPV type 18 E6 oncoprotein in these cells. Cisplatin 114-118 P53 Homo sapiens 173-176 21241554-1 2004 BACKGROUND: To assess the effects of exogenous p73 gene on chemosensitivity of wild-type p53 human lung adenocarcinoma cell A549 to cisplatin (DDP) and adriamycin (ADM). Cisplatin 132-141 P53 Homo sapiens 89-92 15548361-1 2004 According to recent reports, some cancer types exhibit nonrandom allele loss at codon 72 in exon 4 of the p53 gene [coding for proline (72Pro) or arginine (72Arg)]. Arginine 146-154 P53 Homo sapiens 106-109 15548364-2 2004 Besides, p73 was shown to be activated by only a subset of signals that activate p53, such as gamma-irradiation and cisplatin, but not by other common genotoxic stress-inducing agents such as ultraviolet (UV) irradiation, although many of these signals are also capable of inducing p53-independent cell death. Cisplatin 116-125 P53 Homo sapiens 81-84 15613785-0 2004 Hypergravity induces phosphorylation of p53 at serine 15, but not an expression of p53-downstream genes. Serine 47-53 P53 Homo sapiens 40-43 15613785-2 2004 Hypergravity (20 x g) induced the accumulation of p53 and the phosphorylation of p53 at Ser-15. Serine 88-91 P53 Homo sapiens 81-84 15322241-5 2004 Reporter gene assays revealed the presence of several Ah receptor response-element motifs in the promoter and first intron of the p21(WAF1/CIP1) gene that respond to TCDD-mediated Ah receptor activation independently of p53. Polychlorinated Dibenzodioxins 166-170 P53 Homo sapiens 220-223 15603542-6 2004 Functional assays confirming cell dysfunction and increased apoptosis revealed the rat kidney to be more sensitive to the effects of cisplatin than human kidney as demonstrated by significant decreases in slice ATP and GSH levels, significant increases in caspase 9 and 3 activity, p53 protein levels, and increased DNA laddering. Cisplatin 133-142 P53 Homo sapiens 282-285 15218033-1 2004 Under serum-free conditions, rapamycin, an inhibitor of mammalian target of rapamycin (mTOR), induces a cellular stress response characterized by rapid and sustained activation of the apoptosis signal-regulating kinase 1 (ASK1) signaling pathway and selective apoptosis of cells lacking functional p53. Sirolimus 29-38 P53 Homo sapiens 298-301 15246568-0 2004 Analysis of p53 mutations in cells taken from paraffin-embedded tissue sections of ductal carcinoma in situ and atypical ductal hyperplasia of the breast. Paraffin 46-54 P53 Homo sapiens 12-15 15358195-5 2004 Expression of wt p53, but not that of p53-175 mutant, diminished JAK2 tyrosine phosphorylation in MDAH2774 and Caov-3 cell lines. Tyrosine 70-78 P53 Homo sapiens 17-20 15358195-9 2004 These findings present a possible p53-dependent cellular process of modulating JAK2 tyrosine phosphorylation in ovarian cancer cell lines.

Fluorouracil 106-109 P53 Homo sapiens 178-181 15197326-2 2004 The p53-family members, p63 and p73, are highly similar to p53, yet are differentially activated by IR, UV and cis-platinum via ATM and c-abl/ATR signaling pathways. Cisplatin 111-123 P53 Homo sapiens 4-7 15288541-4 2004 The FACIM assay was used to evaluate the mutagenesis of the flounder TP53 exposed in vitro to benzo[a]pyrene diol epoxide (BPDE). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 94-121 P53 Homo sapiens 69-73 15288541-4 2004 The FACIM assay was used to evaluate the mutagenesis of the flounder TP53 exposed in vitro to benzo[a]pyrene diol epoxide (BPDE). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 123-127 P53 Homo sapiens 69-73 15154850-1 2004 The transcriptional co-activator CBP [CREB (cAMP-response-element-binding protein)-binding protein] and its paralogue p300 play a key role in the regulation of both activity and stability of the tumour suppressor p53. Cyclic AMP 44-48 P53 Homo sapiens 213-216 15154850-3 2004 Direct protein-protein interaction between a central domain of MDM2 and the TAZ1 (transcriptional adaptor zinc-binding domain) [C/H1 (cysteine/histidine-rich region 1)] domain of p300 and subsequent formation of a ternary complex including p53 have been reported previously. Cysteine 134-142 P53 Homo sapiens 240-243 15167899-0 2004 Sensitizing glioma cells to cisplatin by abrogating the p53 response with antisense oligonucleotides. Cisplatin 28-37 P53 Homo sapiens 56-59 15167899-0 2004 Sensitizing glioma cells to cisplatin by abrogating the p53 response with antisense oligonucleotides. Oligonucleotides 84-100 P53 Homo sapiens 56-59 15167899-2 2004 However, as there is also some evidence to the contrary, we studied the relationship of the p53 status to the cellular response of glioma cells that were exposed to cisplatin. Cisplatin 165-174 P53 Homo sapiens 92-95 15167899-5 2004 In U87MG cells, blocking the p53 response by antisense oligonucleotides also sensitized the cells to 2.5 microg/ml cisplatin, and shifted the cellular response from arrest to caspase 3-mediated apoptosis. Oligonucleotides 55-71 P53 Homo sapiens 29-32 15167899-5 2004 In U87MG cells, blocking the p53 response by antisense oligonucleotides also sensitized the cells to 2.5 microg/ml cisplatin, and shifted the cellular response from arrest to caspase 3-mediated apoptosis. Cisplatin 115-124 P53 Homo sapiens 29-32 15302922-6 2004 Multiple p53 sequence alignments with 41 additional species confirmed that Arg-174 is highly conserved. Arginine 75-78 P53 Homo sapiens 9-12 15302922-10 2004 A DNA-free p53 structure model predicts that Arg-174 is important for dimerization, whereas Spalax Lys-174 prevents such interactions. Arginine 45-48 P53 Homo sapiens 11-14 15302922-10 2004 A DNA-free p53 structure model predicts that Arg-174 is important for dimerization, whereas Spalax Lys-174 prevents such interactions. Lysine 99-102 P53 Homo sapiens 11-14 15358233-5 2004 Furthermore, His-p53 and FLAG-XPG, but not PCNA, stimulated the Tg DNA glycosylase/AP lyase activity of GST-NTH1 or NTH1. Histidine 13-16 P53 Homo sapiens 17-20 15266324-4 2004 In vitro experiments on neoplastic germ cell lines showed that their exquisite sensitivity to CDDP could be attributed to p53-dependent and -independent pathways. Cisplatin 94-98 P53 Homo sapiens 122-125 15266324-5 2004 Applying cDNA macroarray, semiquantitative RT-PCR and Western blot analyses, blocking experiments, caspase activity assays, and morphological methods, we sought here to define the p53-independent pathway(s) involved in the CDDP-induced apoptosis. Cisplatin 223-227 P53 Homo sapiens 180-183 15266324-6 2004 For this purpose, we used the human TGCT cell line NCCIT, the mutated p53 of which is known to remain inactive during the course of CDDP-induced apoptosis. Cisplatin 132-136 P53 Homo sapiens 70-73 15266324-10 2004 Thus, our data suggest that CDDP mediates its p53-independent apoptosis-inducing effect on the malignant human testicular germ cells--at least partially--through activation of the MEK-ERK signalling pathway. Cisplatin 28-32 P53 Homo sapiens 46-49 15197326-2 2004 The p53-family members, p63 and p73, are highly similar to p53, yet are differentially activated by IR, UV and cis-platinum via ATM and c-abl/ATR signaling pathways. Cisplatin 111-123 P53 Homo sapiens 59-62 15181149-0 2004 p53 localization at centrosomes during mitosis and postmitotic checkpoint are ATM-dependent and require serine 15 phosphorylation. Serine 104-110 P53 Homo sapiens 0-3 15297111-7 2004 The mechanism of cell death induced by these fatty acids seem to involve with mitochondrial depolarization, lipid accumulation and the levels of C-MYC and P53 mRNA expression. Fatty Acids 45-56 P53 Homo sapiens 155-158 15554555-8 2004 Our results suggest that homozygous arginine at codon 72 of p53 may represent a risk factor for developing ovarian malignancies and may affect the differentiation of endometrial cancer. Arginine 36-44 P53 Homo sapiens 60-63 15254726-5 2004 Expression of p53, p21 and bax was increased, and bcl-2 was decreased in melanoma cells after exposure to atRA at different concentrations for various periods of time. Tretinoin 106-110 P53 Homo sapiens 14-17 15254726-8 2004 These data indicate that p53, p21, bax and bcl-2 proteins were involved in atRA-induced apoptosis in melanoma cells. Tretinoin 75-79 P53 Homo sapiens 25-28 15253698-6 2004 We also showed that p53 is the mediator of apoptosis in the setting of GTP depletion and ischemic injury. Guanosine Triphosphate 71-74 P53 Homo sapiens 20-23 15253698-7 2004 Indeed, salvage of GTP with guanosine prevented the ischemia-induced increase in p53 protein. Guanosine Triphosphate 19-22 P53 Homo sapiens 81-84 15353127-12 2004 The XPC defect reduces the cisplatin treatment-mediated p53 response. Cisplatin 27-36 P53 Homo sapiens 56-59 15254726-0 2004 Expression profiles of p53, p21, bax and bcl-2 proteins in all-trans-retinoic acid treated primary and metastatic melanoma cells. Tretinoin 69-82 P53 Homo sapiens 23-26 15254726-3 2004 In this study, we used a similar cell culture model system of matched primary and metastatic melanoma cells from the same patient to investigate whether p53 and bcl-2 family proteins were involved in atRA-induced apoptosis. Tretinoin 200-204 P53 Homo sapiens 153-156 15254702-6 2004 In this study, we examined induced apoptosis in colon cancer cell lines and the status of p53 expression in response to treatment of HCT116, COLO320, SW480 and DLD1 with 5-FU alone, CDDP alone and FP treatment under flow cytometric analysis. Fluorouracil 170-174 P53 Homo sapiens 90-93 15260130-3 2004 H2O2 increased both the ratio of bax/bcl-2 and the p53 mRNA expression. Hydrogen Peroxide 0-4 P53 Homo sapiens 51-54 15159397-6 2004 Moreover, prior ATM/ATR-dependent phosphorylation of BRCA1 at Ser-1423 or Ser-1524 regulates the ability of ATM/ATR to phosphorylate p53(Ser-15) efficiently. Serine 62-65 P53 Homo sapiens 133-136 15259070-3 2004 Lipofectin mediated p53 or HCV NS5A expression vectors were used to transfect hepatoma cell lines to observe whether HCV NS5A could abrogate the binding ability of p53 to its specific DNA sequence and p53 transactivation on p21 promoter. 1,2-dielaidoylphosphatidylethanolamine 0-10 P53 Homo sapiens 20-23 15363320-0 2004 [Application of immunohistochemistry-laser microdissection-PCR technique in detecting p53 gene mutation in paraffin sections of gastric cancer]. Paraffin 107-115 P53 Homo sapiens 86-89 15363320-2 2004 METHODS: The expression of p53 protein in 41 paraffin-embedded advanced gastric cancer samples was assessed by immunohistochemistry. Paraffin 45-53 P53 Homo sapiens 27-30 15363320-12 2004 CONCLUSIONS: IHC-LMD-PCR technique can be successfully applied in paraffin sections of gastric cancers for the detection of p53 gene mutations. Paraffin 66-74 P53 Homo sapiens 124-127 15159397-6 2004 Moreover, prior ATM/ATR-dependent phosphorylation of BRCA1 at Ser-1423 or Ser-1524 regulates the ability of ATM/ATR to phosphorylate p53(Ser-15) efficiently. Serine 74-77 P53 Homo sapiens 133-136 15159397-6 2004 Moreover, prior ATM/ATR-dependent phosphorylation of BRCA1 at Ser-1423 or Ser-1524 regulates the ability of ATM/ATR to phosphorylate p53(Ser-15) efficiently. Serine 74-77 P53 Homo sapiens 133-136 15159397-7 2004 Phosphorylation of p53(Ser-15) is necessary for an IR-induced G(1)/S arrest via transcriptional induction of the cyclin-dependent kinase inhibitor p21. Serine 23-26 P53 Homo sapiens 19-22 15159397-8 2004 Consistent with these data, repressing p53(Ser-15) phosphorylation by BRCA1-BARD1 depletion compromises p21 induction and the G(1)/S checkpoint arrest in response to IR but not UV radia-tion. Serine 43-46 P53 Homo sapiens 39-42 15251465-0 2004 Thymidylate synthase inhibition triggers glucose-dependent apoptosis in p53-negative leukemic cells. Glucose 41-48 P53 Homo sapiens 72-75 15183530-1 2004 A common germline polymorphism of p53 gene produces an Arginine to Proline change at aminoacid position 72.

Dichlororibofuranosylbenzimidazole 70-73 P53 Homo sapiens 158-161 15094782-3 2004 We have previously found that the kinase and mRNA synthesis inhibitor DRB (5,6-dichloro-1-b-D-ribofuranosylbenzimidazole) induces the nuclear accumulation of p53 without concomitant phosphorylation of the ser15 site of p53, which is thought to be a modification important for the attenuation of p53-MDM2 interaction. Dichlororibofuranosylbenzimidazole 70-73 P53 Homo sapiens 219-222 15256442-8 2004 Ser(392) nonphosphorylated p53 was present in human breast tumors expressing mutant p53 including p53H175.

Resveratrol 15-26 P53 Homo sapiens 83-86 15188005-4 2004 E(2) inhibited resveratrol-stimulated phosphorylation of serines 15, 20 and 392 of p53 and acetylation of p53 in a concentration- and time-dependent manner.

Fluorouracil 98-102 P53 Homo sapiens 50-53 15222051-2 2004 METHODS: After treatment with Ad-p53, LOVO/5-FU sensitivity to 5-Fu was investigated using tetrazolium dye assay. Fluorouracil 63-67 P53 Homo sapiens 33-36 15096505-3 2004 We have demonstrated that DNA damage by doxorubicin and cisplatin caused a steady elevation of the R2 protein in p53(-/-) HCT-116 human colon carcinoma cells but induced degradation of the protein in p53(+/+) cells. Doxorubicin 40-51 P53 Homo sapiens 113-116 15096505-3 2004 We have demonstrated that DNA damage by doxorubicin and cisplatin caused a steady elevation of the R2 protein in p53(-/-) HCT-116 human colon carcinoma cells but induced degradation of the protein in p53(+/+) cells. Doxorubicin 40-51 P53 Homo sapiens 200-203 15096505-3 2004 We have demonstrated that DNA damage by doxorubicin and cisplatin caused a steady elevation of the R2 protein in p53(-/-) HCT-116 human colon carcinoma cells but induced degradation of the protein in p53(+/+) cells. Cisplatin 56-65 P53 Homo sapiens 113-116 15096505-3 2004 We have demonstrated that DNA damage by doxorubicin and cisplatin caused a steady elevation of the R2 protein in p53(-/-) HCT-116 human colon carcinoma cells but induced degradation of the protein in p53(+/+) cells.

Serine 94-100 P53 Homo sapiens 27-30 15226429-3 2004 CDK2 inhibition triggers a p53-p21 response via ATM- and ATR-dependent p53 phosphorylation at serine 15. Serine 94-100 P53 Homo sapiens 71-74 15226436-5 2004 However, IR-activated, ATM-mediated phosphorylation of p53 at serine 15 (human) or 18 (mouse) [Ser15(h)/18(m)], and apoptosis occurred in myoblasts but was impaired in myotubes. Serine 62-68 P53 Homo sapiens 55-58 15242600-4 2004 However, three loops, involved in DNA and Zn binding in human p53, contain small alpha helices in Cep-1. Zinc 42-44 P53 Homo sapiens 62-65 15242600-5 2004 The alpha helix in loop L3 of Cep-1 orients the side chains of two conserved arginines toward DNA; in human p53, both arginines are mutation hotspots, but only one contacts DNA. Arginine 118-127 P53 Homo sapiens 108-111 15102862-3 2004 In this report, we show that doxycycline increased superoxide generation and subsequently activated NF-kappaB, which in turn up-regulated p53 expression and increased the stability and DNA binding activity of p53. Superoxides 51-61 P53 Homo sapiens 138-141 15102862-3 2004 In this report, we show that doxycycline increased superoxide generation and subsequently activated NF-kappaB, which in turn up-regulated p53 expression and increased the stability and DNA binding activity of p53. Superoxides 51-61 P53 Homo sapiens 209-212 15140517-1 2004 OBJECTIVE: To test the hypothesis that p53 homozygous Arg/Arg genotype at codon 72 is a significant risk factor for the development of HPV induced cervical cancer. Arginine 54-57 P53 Homo sapiens 39-42 15159015-4 2004 Furthermore, combined administrations of insulin and paclitaxel affected MAPK pathway, Raf-1 activation and p53 expression levels. Paclitaxel 53-63 P53 Homo sapiens 108-111 15095302-0 2004 Ser-249TP53 mutation in tumour and plasma DNA of hepatocellular carcinoma patients from a high incidence area in the Gambia, West Africa. Serine 0-3 P53 Homo sapiens 7-11 15095302-2 2004 A selective mutation in TP53 (AGG-->AGT at codon 249, Arg-->Ser) has been identified as a hotspot in HCCs from such areas, reflecting DNA damage caused by aflatoxin metabolites. Arginine 57-60 P53 Homo sapiens 24-28 15095302-2 2004 A selective mutation in TP53 (AGG-->AGT at codon 249, Arg-->Ser) has been identified as a hotspot in HCCs from such areas, reflecting DNA damage caused by aflatoxin metabolites. Serine 66-69 P53 Homo sapiens 24-28 15140517-1 2004 OBJECTIVE: To test the hypothesis that p53 homozygous Arg/Arg genotype at codon 72 is a significant risk factor for the development of HPV induced cervical cancer. Arginine 58-61 P53 Homo sapiens 39-42 15178317-0 2004 Protein phosphatase 1, but not protein phosphatase 2A, dephosphorylates DNA-damaging stress-induced phospho-serine 15 of p53. Serine 108-114 P53 Homo sapiens 121-124 15178764-0 2004 Hypoxic inducible factor 1alpha, extracellular signal-regulated kinase, and p53 are regulated by distinct threshold concentrations of nitric oxide. Nitric Oxide 134-146 P53 Homo sapiens 76-79 15178764-5 2004 Hypoxic inducible factor 1alpha (HIF-1alpha) accumulation was associated with an intermediate amount of NO (>100 nM), whereas p53 serine 15 phosphorylation occurred at considerably higher levels (>300 nM). Serine 133-139 P53 Homo sapiens 129-132 15178764-7 2004 HIF-1alpha stabilization paralleled the presence of NO, whereas p53 serine 15 phosphorylation was detected during, and persisted after, NO exposure. Serine 68-74 P53 Homo sapiens 64-67 15054096-3 2004 DOX-mediated cardiomyopathy is linked to its ability to induce apoptosis in endothelial cells and cardiomyocytes by activation of p53 protein and reactive oxygen species. Doxorubicin 0-3 P53 Homo sapiens 130-133 15054096-4 2004 We evaluated the potential roles of H(2)O(2) and p53 in DOX-induced apoptosis in normal bovine aortic endothelial cells and adult rat cardiomyocytes and in tumor cell lines PA-1 (human ovarian teratocarcinoma) and MCF-7 (human breast adenocarcinoma). Doxorubicin 56-59 P53 Homo sapiens 49-52 15054096-6 2004 In contrast, DOX caused early activation of p53 in tumor cells that was followed by caspase-3 activation and DNA fragmentation. Doxorubicin 13-16 P53 Homo sapiens 44-47 15054096-7 2004 These findings suggest that the transcriptional activation of p53 in DOX-induced apoptosis in endothelial cells may not be as crucial as it is in tumor cells. Doxorubicin 69-72 P53 Homo sapiens 62-65 15054096-9 2004 Pifithrin-alpha completely suppressed DOX-induced activation of p53 in both normal and tumor cell lines and prevented apoptosis in tumor cell lines but not in endothelial cells and cardiomyocytes. Doxorubicin 38-41 P53 Homo sapiens 64-67 15175154-3 2004 Both ATM and hSMG-1 phosphorylate Ser/Thr-Gln-containing target sequences in the checkpoint protein p53 and the nonsense-mediated mRNA decay (NMD) protein hUpf1. Serine 34-37 P53 Homo sapiens 100-103 15175154-3 2004 Both ATM and hSMG-1 phosphorylate Ser/Thr-Gln-containing target sequences in the checkpoint protein p53 and the nonsense-mediated mRNA decay (NMD) protein hUpf1. Threonine 38-41 P53 Homo sapiens 100-103 15150572-6 2004 In particular, we found that CA-Akt-expressing cells displayed increased expression of the antiapoptotic Bcl-2 family member protein Bcl-x(l), and a delayed onset of the p53 pathway after treatment with cisplatin or Mitoxantrone. Cisplatin 203-212 P53 Homo sapiens 170-173 15024021-4 2004 During the cisplatin-induced apoptosis in human neuroblastoma SH-SY5Y cells, the expression level of Plk1 was significantly decreased both at mRNA and protein levels, whereas cisplatin treatment caused a remarkable stabilization of p53. Cisplatin 11-20 P53 Homo sapiens 232-235 15024021-4 2004 During the cisplatin-induced apoptosis in human neuroblastoma SH-SY5Y cells, the expression level of Plk1 was significantly decreased both at mRNA and protein levels, whereas cisplatin treatment caused a remarkable stabilization of p53. Cisplatin 175-184 P53 Homo sapiens 232-235 15145520-1 2004 We have previously shown that oligonucleotides designed to bind in triplex fashion to a specific p53 binding site homology inhibit the proliferation of colon cancer cells in vitro. Oligonucleotides 30-46 P53 Homo sapiens 97-100 15135642-0 2004 Mutational biases associated with potential iron-binding DNA motifs in rodent lacI and human p53 mutational databases. Iron 44-48 P53 Homo sapiens 93-96 15178317-2 2004 We investigated whether the inhibition of PP1 by OA promotes the phosphorylation of the serine 15 of p53. Serine 88-94 P53 Homo sapiens 101-104 15178317-5 2004 This report provides the first evidence that PP1, but not PP2A, dephosphorylates phospho-serine 15 of p53. Serine 89-95 P53 Homo sapiens 102-105 14742318-8 2004 Our data were consistent with increased likelihood of tumors with p53 mutations for premenopausal breast cancer with increased alcohol intake 10 or 20 years previous; for intake of 16 or more drinks per month in the period 20 years before the interview compared with non-drinkers, the OR was 5.25, 95% CI 1.48-18.58. Alcohols 127-134 P53 Homo sapiens 66-69 14742318-0 2004 Diet and alcohol consumption in relation to p53 mutations in breast tumors. Alcohols 9-16 P53 Homo sapiens 44-47 15191663-1 2004 BACKGROUND & OBJECTIVE: Recent studies have shown that wild-type p53 gene can enhance the chemosensitivity of the majority of non-small cell lung cancers. Adenosine Monophosphate 12-15 P53 Homo sapiens 69-72 14742318-9 2004 For postmenopausal women, there was increased likelihood of tumors with p53 mutations among women with higher folate. Folic Acid 110-116 P53 Homo sapiens 72-75 14742318-12 2004 For premenopausal women, alcohol consumption in the past was associated with p53 mutations. Alcohols 25-32 P53 Homo sapiens 77-80 15179184-4 2004 Curcumin induced melanoma cell apoptosis and cell cycle arrest, which is associated with the downregulation of NFkappaB activation, iNOS and DNA-dependent protein kinase catalytic subunit expression, and upregulation of p53, p21(Cip1), p27(Kip1) and checkpoint kinase 2. Curcumin 0-8 P53 Homo sapiens 220-223 15145278-1 2004 OBJECTIVES: Although some studies have reported that the arginine isoform on codon 72 of p53 increases the susceptibility to invasive cervical cancer, such data remain controversial. Arginine 57-65 P53 Homo sapiens 89-92 15179185-4 2004 The effect on p53 was not a direct result of inhibition of extracellular signal-regulated kinase-1/2 (ERK1/2) activation by TSA, as treatment of the cells with the mitogen-activated protein kinase/extracellular signal-regulated kinase kinase-1 (MEK1) inhibitor PD98059 did not result in decreased p53 protein level. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 261-268 P53 Homo sapiens 14-17 15138567-13 2004 In this pilot study with a limited number of patients to evaluate the predictive value of p53 mutations for an anthracycline/taxane combination therapy in the neoadjuvant setting, stable disease was observed more often in patients with wild-type p53 but statistical significance was not quite reached for this clear trend. Anthracyclines 111-124 P53 Homo sapiens 90-93 15269478-6 2004 MATERIALS AND METHODS: p53 protein expression was evaluated on formalin-fixed paraffin-embedded sections using streptavidin biotin immunoperoxidase technique after high temperature antigen retrieval. Paraffin 78-86 P53 Homo sapiens 23-26 14967811-9 2004 However, cells overexpressing anterior gradient-2 attenuate p53 phosphorylation at both Ser(15) and Ser(392) and silence p53 transactivation function in ultraviolet (UV)-damaged cells. Serine 88-91 P53 Homo sapiens 60-63 14967811-9 2004 However, cells overexpressing anterior gradient-2 attenuate p53 phosphorylation at both Ser(15) and Ser(392) and silence p53 transactivation function in ultraviolet (UV)-damaged cells. Serine 100-103 P53 Homo sapiens 60-63 15138567-13 2004 In this pilot study with a limited number of patients to evaluate the predictive value of p53 mutations for an anthracycline/taxane combination therapy in the neoadjuvant setting, stable disease was observed more often in patients with wild-type p53 but statistical significance was not quite reached for this clear trend. taxane 125-131 P53 Homo sapiens 90-93 15064747-6 2004 By using cDNA arrays to examine global p53-dependent gene expression in response to adriamycin or p14ARF, we found that most genes were regulated similarly by the two treatments. Doxorubicin 84-94 P53 Homo sapiens 39-42 15161352-1 2004 The accumulation of the cell cycle regulators TP53 and CDKN1A (p21/CIP1/WAF1) was investigated after exposure to X rays and carbon ions (170 keV microm(-1)) and xenon, bismuth and uranium ions (8900-15,000 keV microm(-1)) in normal human fibroblasts. Carbon 124-130 P53 Homo sapiens 46-50 15161352-1 2004 The accumulation of the cell cycle regulators TP53 and CDKN1A (p21/CIP1/WAF1) was investigated after exposure to X rays and carbon ions (170 keV microm(-1)) and xenon, bismuth and uranium ions (8900-15,000 keV microm(-1)) in normal human fibroblasts. Uranium 180-187 P53 Homo sapiens 46-50 15142674-8 2004 A decrease in expression of p53, bcl-2, and bcl-X(L) was observed after 12 h exposure of 40 microM curcumin. Curcumin 99-107 P53 Homo sapiens 28-31 15064747-7 2004 However, a subset of p53-regulated genes whose products have proliferative roles or regulate VEGF activity, newly described here, are repressed by p14ARF much more than by adriamycin. Doxorubicin 172-182 P53 Homo sapiens 21-24 15064747-2 2004 In human U2OS cells, treatment with adriamycin causes p53 to be phosphorylated on all six serine residues tested, leading to the dissociation of p53 from MDM2 and transcription of the p21 and mdm2 genes. Doxorubicin 36-46 P53 Homo sapiens 54-57 15064747-2 2004 In human U2OS cells, treatment with adriamycin causes p53 to be phosphorylated on all six serine residues tested, leading to the dissociation of p53 from MDM2 and transcription of the p21 and mdm2 genes. Doxorubicin 36-46 P53 Homo sapiens 145-148 15064747-8 2004 We conclude that the phosphorylation of p53 on N-terminal serine residues is not required for increased transcription of the great majority of p53-responsive genes and that the induction of p53 by p14ARF, with little phosphorylation, leads to substantial repression of genes whose products have roles in proliferation. Serine 58-64 P53 Homo sapiens 40-43 15064747-2 2004 In human U2OS cells, treatment with adriamycin causes p53 to be phosphorylated on all six serine residues tested, leading to the dissociation of p53 from MDM2 and transcription of the p21 and mdm2 genes. Serine 90-96 P53 Homo sapiens 54-57 15138488-9 2004 TPA (10(-12)-10(-8) mol l(-1)) treatment of LNCaP cells caused their growth inhibition, cell cycle arrest, upregulation of p53 and p21waf1, and induction of apoptosis. Tetradecanoylphorbol Acetate 0-3 P53 Homo sapiens 123-126 15161716-8 2004 Inactivation of p53 in MCF-7 and HCT116 cell lines blocked 5-FU- and antifolate-mediated up-regulation of Fas. Fluorouracil 59-63 P53 Homo sapiens 16-19 15161716-10 2004 Lack of Fas up-regulation in the p53-null and -mutant lines abolished the synergistic interaction between 5-FU and CH-11. Fluorouracil 106-110 P53 Homo sapiens 33-36 15140256-14 2004 In addition, curcumin affected expression of metallothionein genes, tubulin genes, p53 and other genes involved in colon carcinogenesis. Curcumin 13-21 P53 Homo sapiens 83-86 15161705-0 2004 Rapid and sensitive p53 alteration analysis in biopsies from lung cancer patients using a functional assay and a universal oligonucleotide array: a prospective study.

Arginine 81-89 P53 Homo sapiens 0-3 15041222-4 2004 The TP53 gene has a single polymorphism at codon 72 of exon 4 that encodes either arginine (Arg) or proline (Pro). Arginine 82-90 P53 Homo sapiens 4-8 15041222-4 2004 The TP53 gene has a single polymorphism at codon 72 of exon 4 that encodes either arginine (Arg) or proline (Pro). Arginine 92-95 P53 Homo sapiens 4-8 15059920-10 2004 Mutations within the DNA-binding domain of p53, which are usually associated with malignancy, were found to impair the repressive effect of p53 on transcriptional activity of the GLUT1 and GLUT4 gene promoters, thereby resulting in increased glucose metabolism and cell energy supply. Glucose 242-249 P53 Homo sapiens 140-143 14977881-5 2004 VSMC exposed to serum-free medium conditioned by apoptotic EC showed increased ERK 1/2 phosphorylation, enhanced Bcl-xl expression, and inhibition of p53 expression. vsmc 0-4 P53 Homo sapiens 150-153 15037523-0 2004 Role of p53 and p38 MAP kinase in nitric oxide-induced G2/M arrest and apoptosis in the human lung carcinoma cells. Nitric Oxide 34-46 P53 Homo sapiens 8-11 15059885-1 2004 p53-mediated apoptosis may involve the induction of redox-controlling genes, resulting in the production of reactive oxygen species. Reactive Oxygen Species 108-131 P53 Homo sapiens 0-3 15059885-10 2004 We observed both the release of cytochrome C and Ca(2+) from the mitochondria into the cytoplasm and an increased frequency of apoptotic cells after p53 induction in the TR9-7 cells that coincided with an increased expression of MnSOD and GPx, and the level of reactive oxygen species. Reactive Oxygen Species 261-284 P53 Homo sapiens 149-152 15041112-4 2004 p53 immunostaining was performed on paraffin-embedded tissues using monoclonal antibody DO7 and an automated immunostainer. Paraffin 36-44 P53 Homo sapiens 0-3 15034933-3 2004 Prior reports have demonstrated that BRCA1 can exist in cells in a complex with the BRG1-based SWI/SNF ATP-dependent chromatin remodeling enzymes and that SWI/SNF components contribute to p53-mediated gene activation.

Cisplatin 79-88 P53 Homo sapiens 14-17 15165403-0 2004 Identification of a p53-dependent pathway in the induction of apoptosis of human breast cancer cells by the natural product, resveratrol. Resveratrol 125-136 P53 Homo sapiens 20-23 15165403-5 2004 RESULTS: Apoptosis induced by resveratrol was found to occur only in breast cancer cells expressing wild-type p53 but not in mutant p53-expressing cells. Resveratrol 30-41 P53 Homo sapiens 110-113 15165403-6 2004 CONCLUSIONS: We therefore conclude that the natural product, resveratrol, induces apoptosis in breast cancer cells via p53-dependent pathways. Resveratrol 61-72 P53 Homo sapiens 119-122 14968111-5 2004 In both cases, however, HCV core protein increased the p53 DNA-binding affinity in gel retardation analyses, likely due to the hyperacetylation of p53 Lys(373) and Lys(382) residues. Lysine 151-154 P53 Homo sapiens 55-58 14968111-5 2004 In both cases, however, HCV core protein increased the p53 DNA-binding affinity in gel retardation analyses, likely due to the hyperacetylation of p53 Lys(373) and Lys(382) residues. Lysine 151-154 P53 Homo sapiens 147-150 14968111-5 2004 In both cases, however, HCV core protein increased the p53 DNA-binding affinity in gel retardation analyses, likely due to the hyperacetylation of p53 Lys(373) and Lys(382) residues. Lysine 164-167 P53 Homo sapiens 55-58 14968111-6 2004 Additionally, HCV core protein, depending on its expression level, had differential effects on the Ser(15) phosphorylation of p53. Serine 99-102 P53 Homo sapiens 126-129 15010881-7 2004 In addition, the extent to which harringtonine altered the expression of select DNA damage response genes (p53, P16, ERCC1 and XPB) was determined using RT-PCR and Southern hybridization in A2780 and A2780/CP70 cells. harringtonin 33-46 P53 Homo sapiens 107-110 15010881-9 2004 However, harringtonine altered expression of p53 and P16 RNAs in both cell lines, although the down-regulation of p53 and P16 RNAs by harringtonine were more pronounced in A2780 cells. harringtonin 9-22 P53 Homo sapiens 45-48 15010881-9 2004 However, harringtonine altered expression of p53 and P16 RNAs in both cell lines, although the down-regulation of p53 and P16 RNAs by harringtonine were more pronounced in A2780 cells. harringtonin 134-147 P53 Homo sapiens 114-117 15010889-4 2004 To further investigate the molecular mechanisms underlying bladder carcinogenesis with this specific etiology, mutation analysis of p53 gene (exon 5-8) was performed for 11 and 18 paraffin-embedded bladder cancers in Ukrainians, respectively collected before and after the Chernobyl disaster. Paraffin 180-188 P53 Homo sapiens 132-135 15026814-10 2004 Gene transfer of p53 14/19 in combination with the administration of doxorubicin or cisplatin is a potential therapeutic approach for cancers expressing high levels of Mdm2. Doxorubicin 69-80 P53 Homo sapiens 17-20 15053879-0 2004 Phosphorylation on Thr-55 by TAF1 mediates degradation of p53: a role for TAF1 in cell G1 progression. Threonine 19-22 P53 Homo sapiens 58-61 15053879-4 2004 TAF1 interacts with and phosphorylates p53 at Thr-55 in vivo. Threonine 46-49 P53 Homo sapiens 39-42 15084981-11 2004 These results strongly suggest that AxdAdB-3 possesses a wider therapeutic potential than previously believed, given that most pancreatic cancers have abnormalities in both the TP53 and RB pathways. axdadb-3 36-44 P53 Homo sapiens 177-181 15053879-8 2004 Significantly, the Thr-55 phosphorylation was reduced following DNA damage, suggesting that this phosphorylation contributes to the stabilization of p53 in response to DNA damage. Threonine 19-22 P53 Homo sapiens 149-152 15026814-0 2004 A modified p53 enhances apoptosis in sarcoma cell lines mediated by doxorubicin. Doxorubicin 68-79 P53 Homo sapiens 11-14 15026814-6 2004 We demonstrate that doxorubicin induces phosphorylation of both wt p53 and p53 14/19 protein at multiple sites. Doxorubicin 20-31 P53 Homo sapiens 67-70 15026814-6 2004 We demonstrate that doxorubicin induces phosphorylation of both wt p53 and p53 14/19 protein at multiple sites. Doxorubicin 20-31 P53 Homo sapiens 75-78 15026814-10 2004 Gene transfer of p53 14/19 in combination with the administration of doxorubicin or cisplatin is a potential therapeutic approach for cancers expressing high levels of Mdm2. Cisplatin 84-93 P53 Homo sapiens 17-20 14755247-5 2004 The p53 protein remains short-lived in confluent cultures regardless of the extent of DNA damage, even though it undergoes efficient phosphorylation on the mouse equivalent of human p53 serine 15. Serine 186-192 P53 Homo sapiens 182-185 15041737-9 2004 Using semiquantitative reverse transcription-PCR, we have demonstrated down-regulation of thymidine phosphorylase mRNA in both p53(+/+) and p53(-/-) 5-FU-resistant cells, suggesting that decreased production of 5-FU active metabolites may be an important resistance mechanism in these lines. Fluorouracil 149-153 P53 Homo sapiens 140-143 15041737-0 2004 Characterization of p53 wild-type and null isogenic colorectal cancer cell lines resistant to 5-fluorouracil, oxaliplatin, and irinotecan. Fluorouracil 94-108 P53 Homo sapiens 20-23 15041737-0 2004 Characterization of p53 wild-type and null isogenic colorectal cancer cell lines resistant to 5-fluorouracil, oxaliplatin, and irinotecan. Irinotecan 127-137 P53 Homo sapiens 20-23 15041737-5 2004 In addition, we found that resistance to 5-FU and oxaliplatin was higher in parental p53(-/-) cells compared with parental p53(+/+) cells, with an approximately 5-fold increase in IC(50 (72 h)) for each drug. Fluorouracil 41-45 P53 Homo sapiens 85-88 15001399-0 2004 Differential regulation of signal transduction pathways in wild type and mutated p53 breast cancer epithelial cells by copper and zinc. Copper 119-125 P53 Homo sapiens 81-84 15001399-2 2004 This study was undertaken to investigate the role of PI3K/Akt signaling pathway in metal resistance in human breast cancer epithelial cells with different p53 and estrogen receptor status. Metals 83-88 P53 Homo sapiens 155-158 15001399-3 2004 Exposure to copper and zinc increased Akt phosphorylation with its nuclear localization only in MDA-MB-231 cells with no estrogen receptor and mutated p53. Copper 12-18 P53 Homo sapiens 151-154 15001399-6 2004 In contrast, in MCF-7 cells with wild type p53 and estrogen receptor, there was no change in Akt activation, while suppression of p53 activity by pifithrin-alpha increased phosphorylation of Akt after the treatment with copper. Copper 220-226 P53 Homo sapiens 130-133 15001399-7 2004 In MCF-7 cells, the metal treatment increased the phosphorylation of p53 at serine 15, up-regulated p21 expression, and resulted in cell-cycle arrest in G1 phase with apoptosis. Metals 20-25 P53 Homo sapiens 69-72 15001399-7 2004 In MCF-7 cells, the metal treatment increased the phosphorylation of p53 at serine 15, up-regulated p21 expression, and resulted in cell-cycle arrest in G1 phase with apoptosis. Serine 76-82 P53 Homo sapiens 69-72 15001399-8 2004 These results demonstrate that copper-induced apoptosis in MCF-7 cells is p53 dependent, whereas the metal resistance in MDA-MB-231 cells may be due to activation of Akt in the absence of a functional p53. Copper 31-37 P53 Homo sapiens 74-77 15041737-8 2004 These data suggest that p53 may be an important determinant of sensitivity to 5-FU and oxaliplatin but not CPT-11. Fluorouracil 78-82 P53 Homo sapiens 24-27 15041737-5 2004 In addition, we found that resistance to 5-FU and oxaliplatin was higher in parental p53(-/-) cells compared with parental p53(+/+) cells, with an approximately 5-fold increase in IC(50 (72 h)) for each drug. Fluorouracil 41-45 P53 Homo sapiens 123-126 15041737-7 2004 Furthermore, apoptosis after treatment with 5-FU and oxaliplatin, but not CPT-11, was significantly reduced in parental p53(-/-) cells compared with parental p53(+/+) cells. Fluorouracil 44-48 P53 Homo sapiens 120-123 15041737-7 2004 Furthermore, apoptosis after treatment with 5-FU and oxaliplatin, but not CPT-11, was significantly reduced in parental p53(-/-) cells compared with parental p53(+/+) cells. Fluorouracil 44-48 P53 Homo sapiens 158-161 15041737-9 2004 Using semiquantitative reverse transcription-PCR, we have demonstrated down-regulation of thymidine phosphorylase mRNA in both p53(+/+) and p53(-/-) 5-FU-resistant cells, suggesting that decreased production of 5-FU active metabolites may be an important resistance mechanism in these lines. Fluorouracil 211-215 P53 Homo sapiens 127-130 14701864-1 2004 C-terminal truncation of ADAMTS-4 from the p68 form to the p53 form is required for activation of its capacity to cleave the Glu(373)-Ala(374) interglobular domain bond of aggrecan. Glutamic Acid 125-128 P53 Homo sapiens 59-62 14699137-3 2004 We report here that the tumor-promoting phorbol ester 12-O-tetradecanoylphorbol-13-acetate prevents DNA damage-induced up-regulation of p53 by down-regulating PKC delta. Tetradecanoylphorbol Acetate 54-90 P53 Homo sapiens 136-139 14701864-1 2004 C-terminal truncation of ADAMTS-4 from the p68 form to the p53 form is required for activation of its capacity to cleave the Glu(373)-Ala(374) interglobular domain bond of aggrecan. Alanine 134-137 P53 Homo sapiens 59-62 14701864-5 2004 Specific glycosaminoglycan lyase digestions, followed by product analyses using fluorescence-assisted carbohydrate electrophoresis and immunoprecipitation experiments, showed that the p53 form is associated with syndecan-1 through both chondroitin sulfate and heparan sulfate. Carbohydrates 102-114 P53 Homo sapiens 184-187 15177039-3 2004 We previously showed that genistein, a naturally occurring isoflavonoid, induced increased ATM protein kinase activity, ATM-dependent phosphorylation of p53 on serine 15 and activation of the DNA-binding properties of p53. Serine 160-166 P53 Homo sapiens 153-156 15177039-4 2004 Here, we show that genistein also induces phosphorylation of p53 at serines 6, 9, 20, 46, and 392, and that genistein-induced accumulation and phosphorylation of p53 is reduced in two ATM-deficient human cell lines. Serine 68-75 P53 Homo sapiens 61-64 15001986-6 2004 Activated wt-p53 increased apoptosis and enhanced sensitivity to CPT-11. Irinotecan 65-71 P53 Homo sapiens 13-16 15001986-0 2004 Enhanced sensitivity to irinotecan by Cdk1 inhibition in the p53-deficient HT29 human colon cancer cell line.

Alcohols 55-62 P53 Homo sapiens 20-23 15001986-3 2004 Since the DNA-damage checkpoint depends on p53 activation, the status of p53 might critically influence the response to CPT-11. Irinotecan 120-126 P53 Homo sapiens 43-46 15001986-3 2004 Since the DNA-damage checkpoint depends on p53 activation, the status of p53 might critically influence the response to CPT-11. Irinotecan 120-126 P53 Homo sapiens 73-76 15001986-10 2004 We demonstrate a gain of sensitivity to CPT-11 in a p53-mutated colon cancer model either by restoring wild-type p53 function or by sequential treatment with cdk-Is. Irinotecan 40-46 P53 Homo sapiens 52-55 15001986-10 2004 We demonstrate a gain of sensitivity to CPT-11 in a p53-mutated colon cancer model either by restoring wild-type p53 function or by sequential treatment with cdk-Is. Irinotecan 40-46 P53 Homo sapiens 113-116 15023836-1 2004 OBJECTIVES: To analyze the relationship between p53 gene mutations, tobacco smoke, and alcohol consumption in patients with laryngeal squamous cell carcinoma. Alcohols 87-94 P53 Homo sapiens 48-51 15161054-7 2004 CONCLUSION: Observations suggest that the cytotoxicity, cell cycle arrest and apoptosis induced by curcumin and resveratrol in NB cells may be mediated via functionally activated p53 and merit further study. Curcumin 99-107 P53 Homo sapiens 179-182 15161054-0 2004 Curcumin and resveratrol induce apoptosis and nuclear translocation and activation of p53 in human neuroblastoma. Curcumin 0-8 P53 Homo sapiens 86-89 15161054-0 2004 Curcumin and resveratrol induce apoptosis and nuclear translocation and activation of p53 in human neuroblastoma. Resveratrol 13-24 P53 Homo sapiens 86-89 15161054-7 2004 CONCLUSION: Observations suggest that the cytotoxicity, cell cycle arrest and apoptosis induced by curcumin and resveratrol in NB cells may be mediated via functionally activated p53 and merit further study. Resveratrol 112-123 P53 Homo sapiens 179-182 15152939-6 2004 Inactivation of wild-type p53 abrogated the 5-FU-mediated induction of SSAT and annexin II. Fluorouracil 44-48 P53 Homo sapiens 26-29 14757188-1 2004 It has been recently shown that ionizing radiation (IR) and the mRNA synthesis inhibitor 5,6-dichloro-1-b-D-ribofuranosylbenzimidazole (DRB) act in synergy to induce p53-mediated transactivation of reporter plasmids in human cells [Oncogene 19 (2000) 3829]. Dichlororibofuranosylbenzimidazole 136-139 P53 Homo sapiens 166-169 15025498-3 2004 Our studies of the effects of noncytotoxic concentrations of Cd2+ on the levels of p53 and p21 in (+/-)-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE)-treated human fibroblasts showed that Cd2+ decreased BPDE-induced p21 levels in a dose-dependent manner whereas p53 accumulation is attenuated only at higher noncytotoxic concentrations of cadmium. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 147-151 P53 Homo sapiens 83-86 15025498-3 2004 Our studies of the effects of noncytotoxic concentrations of Cd2+ on the levels of p53 and p21 in (+/-)-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE)-treated human fibroblasts showed that Cd2+ decreased BPDE-induced p21 levels in a dose-dependent manner whereas p53 accumulation is attenuated only at higher noncytotoxic concentrations of cadmium. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 206-210 P53 Homo sapiens 83-86 15025498-3 2004 Our studies of the effects of noncytotoxic concentrations of Cd2+ on the levels of p53 and p21 in (+/-)-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE)-treated human fibroblasts showed that Cd2+ decreased BPDE-induced p21 levels in a dose-dependent manner whereas p53 accumulation is attenuated only at higher noncytotoxic concentrations of cadmium. Cadmium 342-349 P53 Homo sapiens 83-86 15025498-4 2004 These findings suggest that both the activity and the accumulation of p53 in response of BPDE treatment are inhibited by Cd2+ although the possibility of p53-independent p21 transactivation cannot be ruled out. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 89-93 P53 Homo sapiens 70-73 15025498-8 2004 Our findings indicate that cadmium not only inhibits NER pathway-dependent repair of BPDE-damaged DNA but also impairs p53 and p21 responses and overrides BPDE-induced G1-S cell cycle arrest. Cadmium 27-34 P53 Homo sapiens 119-122 14991767-0 2004 Cisplatin restores p53 function and enhances the radiosensitivity in HPV16 E6 containing SiHa cells. Cisplatin 0-9 P53 Homo sapiens 19-22 14991767-2 2004 Treatment with 0-20 microM cisplatin for 24 h in HPV16 E6 containing SiHa cells suppressed E6 mRNA, reduced E6 protein, and restored p53 expression in dose-dependent manners. Cisplatin 27-36 P53 Homo sapiens 133-136 14991767-4 2004 After 0-10 microM cisplatin treatment, slightly more apoptotic cells appeared from SiHa cells than those from dominant negative p53-transfected SiHa cells. Cisplatin 18-27 P53 Homo sapiens 128-131 14991767-7 2004 These accompanied with prolonged p53 restoration in irradiated-SiHa cells after 24 h cisplatin treatment and thereafter. Cisplatin 85-94 P53 Homo sapiens 33-36 14991767-10 2004 Therefore, cisplatin restored p53 expression and prolonged IR-induced p53 restoration would be possible candidates to response more sub-G(1) apoptosis in irradiated SiHa cells. Cisplatin 11-20 P53 Homo sapiens 30-33 15012603-5 2004 Evidence is presented that the effects of taxol on ER alpha gene transcription may be mediated through the induction of p53.

Paraffin 96-104 P53 Homo sapiens 59-62 14726466-2 2004 The purpose of this study was to determine whether a p53 microarray could be used to sequence the p53 gene in DNA extracted from formalin-fixed, paraffin-embedded (FFPE) tissues. Paraffin 145-153 P53 Homo sapiens 98-101 14993250-3 2004 The nuclear factor kappaB (NF-kappaB) super repressor had an antimitotic and antiapoptotic effect and prevented the Env-elicited phosphorylation of p53 on serine 15 and 46, as well as the activation of AP1. Serine 155-161 P53 Homo sapiens 148-151 15009673-5 2004 Testosterone treatment induced all gene targets of p53, and amplified the induction of these genes induced by kainate.

Cisplatin 67-76 P53 Homo sapiens 45-48 14576150-10 2004 Together, these data strongly suggest that endogenously produced nitric oxide is required for cisplatin-induced p53 activation and p21(Waf1/Cip1/Sdi1) expression, which can regulate melanoma sensitivity to cisplatin.

Fluorouracil 175-179 P53 Homo sapiens 48-51 14704126-10 2004 CONCLUSION: These results indicated that the wt p53 gene transfection not only induced suppression of cell growth, but also increased the sensitivity of Bel7402/5-FU cells to 5-FU, vincristine, and doxorubicin.

Arginine 14-17 P53 Homo sapiens 0-4 14734461-5 2004 However, the age-related increase in the percentage of codon 72 arginine p53 was not correlated to the prognosis for gastric cancer patients. Arginine 64-72 P53 Homo sapiens 73-76 14734461-8 2004 CONCLUSIONS: These findings indicate that codon 72 arginine p53 may not be associated with a prolonged survival in patients with advanced gastric adenocarcinoma, but further study is needed to assess whether this polymorphism is associated with a late onset or slow progress of early gastric adenocarcinoma.

Serine 35-38 P53 Homo sapiens 28-31 14513366-5 2003 Although phosphorylation of p53 at Ser-392 was also observed in CDDP-treated sensitive and resistant cells, it was weak or absent in response to DACH-Ac-Pt. cddp 64-68 P53 Homo sapiens 28-31 14675203-6 2003 The frequency of the p53 Arg allele was 78.2% in cases and 73.2% in controls (p=0.045), and the genotype frequencies of p53 Arg/Arg, Arg/Pro, and Pro/Pro were 62.6%, 31.1%, and 6.3%, respectively, in the cases, and 53.9%, 38.6%, and 7.5%, respectively, in the controls (p=0.096). Arginine 25-28 P53 Homo sapiens 21-24 14675203-7 2003 Logistic regression analysis revealed that the p53 Arg/Arg genotype was associated with a significantly increased risk of melanoma (adjusted odds ratio (OR)=1.43; 95% confidence interval (CI)=1.02-2.02) compared with other genotypes, and this association was more evident in subgroups of older subjects (OR=2.32; 95% CI=1.39-388), and subjects with Fitzpatrick"s skin type III or IV (OR=1.69; 95% CI=1.11-2.59).

Oxygen 59-65 P53 Homo sapiens 177-180 14617104-5 2003 The effect of AGI-1140 and UVB on phosphorylation of p53 serine 15 in human keratinocytes was examined by Western blotting, while the release of tumor necrosis factor-alpha (TNF-alpha) and prostaglandin E2 (PGE2) was determined by enzyme-linked immunosorbent assay. Dinoprostone 207-211 P53 Homo sapiens 53-56 14674700-4 2003 In both cell types, treatment of hypoxic cells with a reversible selective iNOs inhibitor, Now-nitro-L-arginine (LNNA), blocked iNOs, Bcl-2, and HSP-70 mRNA, but increased p53. now-nitro-l-arginine 91-111 P53 Homo sapiens 172-175 14617104-5 2003 The effect of AGI-1140 and UVB on phosphorylation of p53 serine 15 in human keratinocytes was examined by Western blotting, while the release of tumor necrosis factor-alpha (TNF-alpha) and prostaglandin E2 (PGE2) was determined by enzyme-linked immunosorbent assay. Serine 57-63 P53 Homo sapiens 53-56 14617104-9 2003 However, whereas UVB induced G2 cell cycle arrest with phosphorylation of p53 at serine 15, AGI-1140 induced G1 cell cycle arrest without this phosphorylation. Serine 81-87 P53 Homo sapiens 74-77 14506283-5 2003 Tryptophan fluorescence assays showed that an EBNA1 peptide mapping to residues 395-450 was sufficient to bind the USP7 N-terminal domain and did so with a dissociation constant of 0.9-2 microM, whereas p53 peptides spanning the USP7-binding region gave dissociation constants of 9-17 microM in the same assay. Tryptophan 0-10 P53 Homo sapiens 203-206 14703431-1 2003 OBJECTIVE: To investigate the relationship between apoptosis induced by CD3epsilon and 5-fluorouracil (5-FU), and study the P53 expression in the apoptosis process provide a novel insight and useful information of the apoptosis signaling pathway induced by CD3epsilon and/or 5-FU, and an important implication for the treatment of T-lymphocyte leukemia. Fluorouracil 275-279 P53 Homo sapiens 124-127 14703431-5 2003 RESULTS: CD3epsilon or 5-FU induced apoptosis of TJK with increase of P53 expression. Fluorouracil 23-27 P53 Homo sapiens 70-73 14703431-6 2003 Co-treatment with CD3epsilon specific antibody and 5-FU elevated the apoptotic rates and P53 expression in TJK cells remarkably. Fluorouracil 51-55 P53 Homo sapiens 89-92 14703431-7 2003 The cells transfected with wild-type p53 exhibited more sensitivity to 5-FU than that transfected with mutant p53. Fluorouracil 71-75 P53 Homo sapiens 37-40 14703431-8 2003 CONCLUSION: Co-treatment of CD3epsilon and 5-FU increases the apoptosis and p53 expression, suggesting that there is a synergetic role of CD3epsilon and 5-FU on T lymphocytes. Fluorouracil 43-47 P53 Homo sapiens 76-79 14703431-8 2003 CONCLUSION: Co-treatment of CD3epsilon and 5-FU increases the apoptosis and p53 expression, suggesting that there is a synergetic role of CD3epsilon and 5-FU on T lymphocytes.

Fluorouracil 71-85 P53 Homo sapiens 0-4 14633737-9 2003 Treatment with Let, Tam, or E2W resulted in a dose- and time-dependent increase in active caspase-7 and up-regulation of p53 and p21 protein. Tamoxifen 20-23 P53 Homo sapiens 121-124 14654539-1 2003 PURPOSE: Recent studies have found an association between certain TP53 mutations and resistance to anthracycline-based primary medical therapy in breast cancer. Anthracyclines 99-112 P53 Homo sapiens 66-70 14654539-2 2003 The purpose of this study was to investigate whether TP53 mutational status also might influence the response to a non-anthracycline-containing regimen in primary breast cancer. Anthracyclines 119-132 P53 Homo sapiens 53-57 14654539-6 2003 CONCLUSION: This study revealed a significant association between lack of response to 5-fluorouracil and mitomycin and mutations affecting the L2/L3 domains of the p53 protein. Fluorouracil 86-100 P53 Homo sapiens 164-167 14654539-7 2003 Together with our previous finding that such mutations predict resistance to weekly doxorubicin, our data suggest that mutations affecting this particular domain of the p53 protein may cause resistance to several different cytotoxic compounds applied in breast cancer treatment. Doxorubicin 84-95 P53 Homo sapiens 169-172 14595027-4 2003 Fl-CDB3 was taken up into the cytoplasm and nucleus and induced a substantial up-regulation of wild-type p53 protein and representative mutants. fl-cdb3 0-7 P53 Homo sapiens 105-108 14592451-0 2003 Profound negative regulatory effects by resveratrol on vascular smooth muscle cells: a role of p53-p21(WAF1/CIP1) pathway. Resveratrol 40-51 P53 Homo sapiens 95-98 14592451-5 2003 Resveratrol caused a dose-dependent increase in intracellular p53 and p21(WAF1/CIP1) levels.

Histidine 25-28 P53 Homo sapiens 33-36 14595027-7 2003 Fl-CDB3 sensitized cancer cells that carried wild-type p53 to p53-dependent gamma-radiation-induced apoptosis. fl-cdb3 0-7 P53 Homo sapiens 55-58 14595027-7 2003 Fl-CDB3 sensitized cancer cells that carried wild-type p53 to p53-dependent gamma-radiation-induced apoptosis. fl-cdb3 0-7 P53 Homo sapiens 62-65 14595027-8 2003 Although Fl-CDB3 did not elicit a full biological response, it did bind to and rescue p53 in cells and so can serve as a lead for the development of novel drugs for anticancer therapy. fl-cdb3 9-16 P53 Homo sapiens 86-89 14598320-7 2003 Conversely, DNA damage-induced reactive oxygen species generation was inhibited significantly by gene disruption of p53, Apaf-1, or caspase-9, and combined deficiency of Bax and Bak, but not by caspase-3 or caspase-6 deficiency. Reactive Oxygen Species 31-54 P53 Homo sapiens 116-119 14603254-4 2003 To further evaluate the link between IkBm and sensitivity to Dox and VCR, we demonstrated that both endogenous IkBalpha and ectopic IkBm bind to p53. Doxorubicin 61-64 P53 Homo sapiens 145-148 14603254-5 2003 In response to Dox, the cytosolic p53.IkBalpha complex rapidly dissociated due to downregulation of IkBalpha. Doxorubicin 15-18 P53 Homo sapiens 34-37 14603254-7 2003 Although treatment of EU-1/IkBm cells with Dox increased the expression of p53, the nondissociating p53.IkBm complex resulted in decreased p53 function, as demonstrated by absence of cell-cycle arrest and induction of p53 target genes. Doxorubicin 43-46 P53 Homo sapiens 75-78 14603254-7 2003 Although treatment of EU-1/IkBm cells with Dox increased the expression of p53, the nondissociating p53.IkBm complex resulted in decreased p53 function, as demonstrated by absence of cell-cycle arrest and induction of p53 target genes. Doxorubicin 43-46 P53 Homo sapiens 100-103 14603254-7 2003 Although treatment of EU-1/IkBm cells with Dox increased the expression of p53, the nondissociating p53.IkBm complex resulted in decreased p53 function, as demonstrated by absence of cell-cycle arrest and induction of p53 target genes. Doxorubicin 43-46 P53 Homo sapiens 100-103 14603254-7 2003 Although treatment of EU-1/IkBm cells with Dox increased the expression of p53, the nondissociating p53.IkBm complex resulted in decreased p53 function, as demonstrated by absence of cell-cycle arrest and induction of p53 target genes. Doxorubicin 43-46 P53 Homo sapiens 100-103 14981901-6 2003 Only one tumour, which previously had shown expression and mutation in the p53, had a point mutation at codon 117 of exon 2 of the p21 gene with a resulting Cys-->Tyr amino acid substitution. Cysteine 157-160 P53 Homo sapiens 75-78 14612499-1 2003 We established previously that X-linked inhibitor of apoptosis protein (Xiap) is a determinant of cisplatin (CDDP) resistance in human ovarian cancer cells and that down-regulation of Xiap sensitizes cells to CDDP in the presence of wild-type p53. Cisplatin 98-107 P53 Homo sapiens 243-246 14612499-1 2003 We established previously that X-linked inhibitor of apoptosis protein (Xiap) is a determinant of cisplatin (CDDP) resistance in human ovarian cancer cells and that down-regulation of Xiap sensitizes cells to CDDP in the presence of wild-type p53. Cisplatin 109-113 P53 Homo sapiens 243-246 14612499-1 2003 We established previously that X-linked inhibitor of apoptosis protein (Xiap) is a determinant of cisplatin (CDDP) resistance in human ovarian cancer cells and that down-regulation of Xiap sensitizes cells to CDDP in the presence of wild-type p53. Cisplatin 209-213 P53 Homo sapiens 243-246 14612499-5 2003 Furthermore, dominant-negative Akt sensitizes ovarian cancer cells to CDDP (10 micro M), an effect that is absent in cells expressing mutant p53 or treated with the p53 inhibitor pifithrin-alpha-hydrobromide (30 micro M) but restored by exogenous wild-type p53. Cisplatin 70-74 P53 Homo sapiens 165-168 14612499-5 2003 Furthermore, dominant-negative Akt sensitizes ovarian cancer cells to CDDP (10 micro M), an effect that is absent in cells expressing mutant p53 or treated with the p53 inhibitor pifithrin-alpha-hydrobromide (30 micro M) but restored by exogenous wild-type p53. Cisplatin 70-74 P53 Homo sapiens 165-168 14612499-5 2003 Furthermore, dominant-negative Akt sensitizes ovarian cancer cells to CDDP (10 micro M), an effect that is absent in cells expressing mutant p53 or treated with the p53 inhibitor pifithrin-alpha-hydrobromide (30 micro M) but restored by exogenous wild-type p53. pifithrin-alpha-hydrobromide 179-207 P53 Homo sapiens 165-168 14612499-5 2003 Furthermore, dominant-negative Akt sensitizes ovarian cancer cells to CDDP (10 micro M), an effect that is absent in cells expressing mutant p53 or treated with the p53 inhibitor pifithrin-alpha-hydrobromide (30 micro M) but restored by exogenous wild-type p53. pifithrin-alpha-hydrobromide 179-207 P53 Homo sapiens 165-168 14612499-6 2003 CDDP increased p53, decreased Xiap content, and induced apoptosis in OV2008 cells but not in the resistant counterpart (C13*). Cisplatin 0-4 P53 Homo sapiens 15-18 14612499-10 2003 These results suggest that whereas Xiap, Akt2, and p53 are important mediators of chemoresistance in ovarian cancer cells, Akt2 may be an important regulator of both Xiap and p53 contents after CDDP challenge. Cisplatin 194-198 P53 Homo sapiens 175-178 14675321-2 2003 Studies have suggested that steroid hormones may enhance the expression of these genes leading to loss of p53 gene-mediated cell apoptosis.

Cisplatin 22-31 P53 Homo sapiens 307-310 14534679-9 2003 A number of experimental strategies to overcome cisplatin resistance are at the preclinical or clinical level such as introduction of the bax gene, inhibition of the JNK pathway, introduction of a functional p53 gene, treatment of tumors with aldose reductase inhibitors and others. Cisplatin 48-57 P53 Homo sapiens 208-211 14693272-7 2003 To determine whether cisplatin increases sensitivity of J82 cells to Ad5CMV-p53, we performed median effect analysis for cisplatin combined with Ad5CMV-p53 or DL312. Cisplatin 21-30 P53 Homo sapiens 76-79 14572637-8 2003 In adriamycin-treated cells, p53 was stabilized and induced the expression of p21(CIP1/WAF1), but the expression of ING1b was not affected.

Hydrocortisone 29-43 P53 Homo sapiens 203-206 14562046-4 2003 In cells responding to cisplatin, although p53 is stabilized and activated, EBV latent gene expression appears to inhibit the accumulation of newly synthesized p21(WAF1/CIP1) and the downregulation of cyclin D2 that occur in the normal cells. Cisplatin 23-32 P53 Homo sapiens 43-46 14555213-1 2003 Glucocorticoids (GC) such as hydrocortisone and dexamethasone (DEX) protect steroidogenic granulosa cells against apoptosis induced by serum deprivation, cAMP, tumor necrosis factor alpha stimulation or p53 activation.

Arginine 117-125 P53 Homo sapiens 17-20 14581358-5 2003 RESULTS: We found that the retention of the p53 codon 72 arginine allele in the tumor tissue of proline/arginine heterozygous breast cancer patients is associated with statistically significant reduced disease-free and overall survivals. Arginine 57-65 P53 Homo sapiens 44-47 14581358-5 2003 RESULTS: We found that the retention of the p53 codon 72 arginine allele in the tumor tissue of proline/arginine heterozygous breast cancer patients is associated with statistically significant reduced disease-free and overall survivals. Arginine 104-112 P53 Homo sapiens 44-47 14581358-6 2003 CONCLUSIONS: Our findings suggest that the genotyping for p53 codon 72 locus in both the tumor tissue and in the lymph node of breast cancer patients could contribute to identify a subset of arginine/proline heterozygous patients who have a reduced survival that is associated with the specific retention of the arginine allele in the tumor tissue. Arginine 191-199 P53 Homo sapiens 58-61 14581358-6 2003 CONCLUSIONS: Our findings suggest that the genotyping for p53 codon 72 locus in both the tumor tissue and in the lymph node of breast cancer patients could contribute to identify a subset of arginine/proline heterozygous patients who have a reduced survival that is associated with the specific retention of the arginine allele in the tumor tissue. Arginine 312-320 P53 Homo sapiens 58-61 14583461-11 2003 Abnormal S10P in p53-/- cells was also observed under completely different experimental conditions where cells were treated with nocodazole to induce G(2)-M arrest and elevation of S10P (which is linked with G(2)-M of the cell cycle). Nocodazole 129-139 P53 Homo sapiens 17-20 14583461-0 2003 Loss of p53 has site-specific effects on histone H3 modification, including serine 10 phosphorylation important for maintenance of ploidy. Serine 76-82 P53 Homo sapiens 8-11 14583461-12 2003 On removal of nocodazole, the p53+/+ cells exhibited rapid reduction in S10P levels and cell cycle recovery. Nocodazole 14-24 P53 Homo sapiens 30-33 14583461-7 2003 We provide evidence that p53 influences histone H3 acetylation at lysine 9 (K9) and K14, whereas acetylation of K18 appears to be p53 independent. Lysine 66-72 P53 Homo sapiens 25-28 12890678-6 2003 Similarly, p53 activation by H2O2 was inhibited by kinase-inactive forms of the PDGF beta receptor or ATM. Hydrogen Peroxide 29-33 P53 Homo sapiens 11-14 12890678-9 2003 Thus, these data link PDGF beta receptor transactivation to H2O2-induced p53 phosphorylation and suggest a functional role for growth factor receptors in modulation of p53 function. Hydrogen Peroxide 60-64 P53 Homo sapiens 73-76 12890678-3 2003 In response to H2O2, we observed phosphorylation of p53 specifically at serine 15, but not serine 9, 20, or 392. Hydrogen Peroxide 15-19 P53 Homo sapiens 52-55 12844488-8 2003 However, the p53 mutation frequency increased with the increased number of the combined genotypes among XPD 312WT (Asp/Asp), XPD 751VT (Lys/Gln or Gln/Gln) or XRCC1 399VT (Arg/Gln or Gln/Gln) (P = 0.01, trend test). Lysine 136-139 P53 Homo sapiens 13-16 12890678-3 2003 In response to H2O2, we observed phosphorylation of p53 specifically at serine 15, but not serine 9, 20, or 392.

Serine 19-22 P53 Homo sapiens 94-97 12890678-4 2003 Phosphorylation of Ser-15 was correlated with enhanced induction and functional activation of p53 manifest as transcription of the p53 target p21CIP/WAF. Serine 19-22 P53 Homo sapiens 131-134 12890678-5 2003 We found that H2O2 induced phosphorylation of the PDGF beta receptor and increased ATM kinase activity, two events integral to p53 activation as either AG1433 (a PDGF beta receptor inhibitor) or caffeine (an ATM kinase inhibitor) inhibited Ser-15 phosphorylation.

Sulfhydryl Compounds 105-110 P53 Homo sapiens 12-15 14580323-4 2003 In the absence of DTT, p53 contains only four thiol groups, indicating that an average of one surface thiol group is readily susceptible to oxidation. Sulfhydryl Compounds 46-51 P53 Homo sapiens 23-26 14580323-4 2003 In the absence of DTT, p53 contains only four thiol groups, indicating that an average of one surface thiol group is readily susceptible to oxidation. Sulfhydryl Compounds 102-107 P53 Homo sapiens 23-26 14580323-5 2003 Sulfite-mediated disulfide bond cleavage followed by reaction with 2-nitro-5-thiosulfobenzoate showed that oxidized p53 contains a single disulfide bond per monomer. Sulfites 0-7 P53 Homo sapiens 116-119 14580323-5 2003 Sulfite-mediated disulfide bond cleavage followed by reaction with 2-nitro-5-thiosulfobenzoate showed that oxidized p53 contains a single disulfide bond per monomer. Disulfides 17-26 P53 Homo sapiens 116-119 14580323-5 2003 Sulfite-mediated disulfide bond cleavage followed by reaction with 2-nitro-5-thiosulfobenzoate showed that oxidized p53 contains a single disulfide bond per monomer. Disulfides 138-147 P53 Homo sapiens 116-119 14580323-10 2003 The possibility that oxidized p53 contained significant amounts of sulfenic (-SOH), sulfinic (-SO2H), or sulfonic acid (-SO3H) was ruled out. sulfinic 84-92 P53 Homo sapiens 30-33 12869419-0 2003 The effect of potent iron chelators on the regulation of p53: examination of the expression, localization and DNA-binding activity of p53 and the transactivation of WAF1. Iron 21-25 P53 Homo sapiens 134-137 12869419-10 2003 Our experiments demonstrated: (i) that the elevated WAF1 mRNA expression after Fe chelation was due to increased transcription and also to a post-transcriptional mechanism that was sensitive to cycloheximide; and (ii) that Fe-chelation increased WAF1 expression through a p53-independent pathway. Iron 79-81 P53 Homo sapiens 272-275 12844488-8 2003 However, the p53 mutation frequency increased with the increased number of the combined genotypes among XPD 312WT (Asp/Asp), XPD 751VT (Lys/Gln or Gln/Gln) or XRCC1 399VT (Arg/Gln or Gln/Gln) (P = 0.01, trend test).

Aspirin 159-162 P53 Homo sapiens 37-40 14511359-10 2003 In the meanwhile, phosphorylation of p53 at serine 15, accumulation of p53 and increased the expression of its downstream target genes, p21 and Bax induced by ASA. Aspirin 159-162 P53 Homo sapiens 71-74 14511359-13 2003 Inhibited the activation of p42/p44 mitogen-activated protein kinase (MAPK) by PD98059, a specific inhibitor of extracellular regulatory kinase (ERK), significantly decreased cell viability and enhanced the expression of p53 induced by ASA. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 79-86 P53 Homo sapiens 221-224 14511359-13 2003 Inhibited the activation of p42/p44 mitogen-activated protein kinase (MAPK) by PD98059, a specific inhibitor of extracellular regulatory kinase (ERK), significantly decreased cell viability and enhanced the expression of p53 induced by ASA. Aspirin 236-239 P53 Homo sapiens 221-224 14511359-16 2003 Our study presents evidences that activation of p53 signalling involved in apoptosis induced by ASA. Aspirin 96-99 P53 Homo sapiens 48-51 14619538-5 2003 These results indicate that the type of p53 expression might play an important role in the determination of response to low-dose CDDP + 5-FU therapy in colon cancer patients. Cisplatin 129-133 P53 Homo sapiens 40-43 14619538-5 2003 These results indicate that the type of p53 expression might play an important role in the determination of response to low-dose CDDP + 5-FU therapy in colon cancer patients.

Vitamin D 0-9 P53 Homo sapiens 29-32 14507860-12 2003 There was an increase in staining for p53 and p21 in areas associated with cell death in specimens treated with vitamin D analogues. Vitamin D 112-121 P53 Homo sapiens 38-41 14529565-0 2003 Overexpression of wild-type p53 gene renders MCF-7 breast cancer cells more sensitive to the antiproliferative effect of progesterone. Progesterone 121-133 P53 Homo sapiens 28-31 14529565-2 2003 Because the tumor suppressor protein p53 plays a central role in normal cell growth and in tumor suppression, we have examined the effect of progesterone on the levels of this protein in MCF-7 cells. Progesterone 141-153 P53 Homo sapiens 37-40 14529565-7 2003 We show here that progesterone significantly enhances growth inhibition and apoptosis in MCF-7 cells overexpressing p53, but not in cells transfected with the control vector. Progesterone 18-30 P53 Homo sapiens 116-119 14529565-8 2003 These data suggest that re-establishing p53 function in MCF-7 breast cancer cells renders them more sensitive to the growth inhibitory effect of progesterone. Progesterone 145-157 P53 Homo sapiens 40-43 14517281-7 2003 We found that 14-3-3 sigma interacted with p53 in response to the DNA-damaging agent adriamycin. Doxorubicin 85-95 P53 Homo sapiens 43-46 12963997-4 2003 This anti-proliferative effect of resveratrol was associated with a marked inhibition of the phosphorylation of the retinoblastoma protein (pRB) and concomitant induction of cyclin-dependent kinase (Cdk) inhibitor p21WAF1/CIP, which appears to be transcriptionally upregulated and is p53- dependent. Resveratrol 34-45 P53 Homo sapiens 284-287 14502645-2 2003 Accordingly, HDAC inhibitors such as trichostatin A (TSA) have potential utility in pancreatic cancer, as most of these tumors possess mutations in p53, which in fact is the main cause of chemoresistance to 5-fluorouracil. Fluorouracil 207-221 P53 Homo sapiens 148-151 14577584-3 2003 This degradation is controlled by a common polymorphism of the p53 gene encoding either a proline or an arginine at its codon 72 in exon 4. Arginine 104-112 P53 Homo sapiens 63-66 14578467-4 2003 Using doxorubicin treatment in the HCT116 colon cancer cell line, we have shown that MIC-1 secretion into culture media is correlated with p53 pathway activation as measured by the up-regulation of its downstream transcriptional target p21. Doxorubicin 6-17 P53 Homo sapiens 139-142 14578467-6 2003 Treatment of these animals with a single dose of doxorubicin led to activation of the p53 pathway and a nearly 4-fold elevation of the plasma MIC-1 level, which was paralleled by p21 induction in the tumor xenografts. Doxorubicin 49-60 P53 Homo sapiens 86-89 14577584-4 2003 Recently, it has been demonstrated that the presence of homozygous arginine at codon 72 renders p53 about seven times more susceptible to E6-mediated proteolytic degradation as well as to cervical cancer than those with proline homozygotes or proline/arginine heterozygotes. Arginine 67-75 P53 Homo sapiens 96-99 14577584-4 2003 Recently, it has been demonstrated that the presence of homozygous arginine at codon 72 renders p53 about seven times more susceptible to E6-mediated proteolytic degradation as well as to cervical cancer than those with proline homozygotes or proline/arginine heterozygotes. Arginine 251-259 P53 Homo sapiens 96-99 14577584-12 2003 Thus the interaction between HPV oncoproteins and the p53 gene polymorphism specifically, homozygous arginine at codon 72 appears to play no role in the development of either cervical or oral cancer and also it can not serve as a biomarker for early identification of cervical, oral or breast cancer. Arginine 101-109 P53 Homo sapiens 54-57 12857758-4 2003 Presently, we show that p53 is phosphorylated on Ser-15 following DNA damage and this occurs independently of the CDK pathway. Serine 49-52 P53 Homo sapiens 24-27 12860987-1 2003 Modification-specific antibodies were used to characterize the phosphorylation and acetylation of human p53 in response to genotoxic (UV, IR, and adriamycin) and non-genotoxic (PALA, taxol, nocodazole) stress in cultured human cells at 14 known modification sites. Doxorubicin 146-156 P53 Homo sapiens 104-107 12860987-1 2003 Modification-specific antibodies were used to characterize the phosphorylation and acetylation of human p53 in response to genotoxic (UV, IR, and adriamycin) and non-genotoxic (PALA, taxol, nocodazole) stress in cultured human cells at 14 known modification sites. Paclitaxel 183-188 P53 Homo sapiens 104-107 12860987-1 2003 Modification-specific antibodies were used to characterize the phosphorylation and acetylation of human p53 in response to genotoxic (UV, IR, and adriamycin) and non-genotoxic (PALA, taxol, nocodazole) stress in cultured human cells at 14 known modification sites. Nocodazole 190-200 P53 Homo sapiens 104-107 12860987-3 2003 IR-induced phosphorylation reached a maximum 2 h after treatment and returned to near pretreatment levels by 72 h; UV light and adriamycin induced a less rapid but more robust and prolonged p53 phosphorylation, which reached a maximum between 8 and 24 h, but persisted (UV) even 96 h after treatment. Doxorubicin 128-138 P53 Homo sapiens 190-193 12860987-5 2003 The non-genotoxic agents PALA, taxol and nocodazole induced p53 accumulation and phosphorylation at Ser6, Ser33, Ser46, and Ser392. Paclitaxel 31-36 P53 Homo sapiens 60-63 12860987-5 2003 The non-genotoxic agents PALA, taxol and nocodazole induced p53 accumulation and phosphorylation at Ser6, Ser33, Ser46, and Ser392. Nocodazole 41-51 P53 Homo sapiens 60-63 12860987-8 2003 Analysis of single site mutant p53s indicated clear interdependences between N-terminal phosphorylation sites, which could be classified in four clusters: Ser6 and Ser9; Ser9, Ser15, Thr18 and Ser20; Ser33 and Ser37; and Ser46. UNII-PYZ33YLR8A 183-188 P53 Homo sapiens 31-34 12969788-6 2003 Furthermore, the synthetic bile acids increased the levels of Cdk inhibitor, p21WAF1/CIP1, expression and activated the reporter construct of p21WAF1/CIP1 promoter in p53-independent manner, and p21WAF1/CIP1 proteins induced by the synthetic bile acid derivatives were associated with Cdk2 and proliferating cell nuclear antigen. Bile Acids and Salts 27-37 P53 Homo sapiens 167-170 13130078-10 2003 MDM2 inhibitors such as second-generation antisense oligonucleotides have a broad spectrum of antitumor activities in human cancers regardless of p53 status, providing novel approaches to therapy of human prostate cancer. Oligonucleotides 52-68 P53 Homo sapiens 146-149 12969788-6 2003 Furthermore, the synthetic bile acids increased the levels of Cdk inhibitor, p21WAF1/CIP1, expression and activated the reporter construct of p21WAF1/CIP1 promoter in p53-independent manner, and p21WAF1/CIP1 proteins induced by the synthetic bile acid derivatives were associated with Cdk2 and proliferating cell nuclear antigen. Bile Acids and Salts 27-36 P53 Homo sapiens 167-170 14522900-11 2003 In addition, we found that p33(ING1b) physically interacts with hSIR2, reverses its ability to induce the AFP promoter, and induces acetylation of p53 residues at Lys(373) and/or Lys(382). Lysine 163-166 P53 Homo sapiens 147-150 12866025-1 2003 In cells lacking a functional p53 tumor suppressor protein, the endogenous free radical nitric oxide (NO) appears to inhibit apoptosis, and thereby promotes growth of cancer cells. Nitric Oxide 88-100 P53 Homo sapiens 30-33 12866025-8 2003 In conclusion, NO effectively inhibits apoptosis by scavenging superoxide anions generated in the mitochondria of p53 mutant cells and thereby prevents the downregulation of the antiapoptotic factor bcl-X(L), which controls the mitochondrial apoptosis pathway. Superoxides 63-80 P53 Homo sapiens 114-117 12968928-5 2003 X-ray-induced phosphorylation of Ser 15 of p53/TP53, accumulation of both p53/TP53 and p21/WAF1/CDKN1A, and phosphorylation of XRCC4 were all suppressed. Serine 33-36 P53 Homo sapiens 43-46 12968928-5 2003 X-ray-induced phosphorylation of Ser 15 of p53/TP53, accumulation of both p53/TP53 and p21/WAF1/CDKN1A, and phosphorylation of XRCC4 were all suppressed. Serine 33-36 P53 Homo sapiens 47-51 12927789-0 2003 Morphine suppresses lymphocyte apoptosis by blocking p53-mediated death signaling. Morphine 0-8 P53 Homo sapiens 53-56 12919725-1 2003 The p53 gene has a polymorphism at codon 72 that presents the arginine or proline genotype, although this polymorphism has been associated with genetically determined susceptibility to lung cancers, the literature has not been consistent with this association. Arginine 62-70 P53 Homo sapiens 4-7 12939617-6 2003 We show that the potent activator resveratrol, a polyphenol found in red wine, lowers the Michaelis constant of SIRT1 for both the acetylated substrate and NAD(+), and increases cell survival by stimulating SIRT1-dependent deacetylation of p53. Resveratrol 34-45 P53 Homo sapiens 240-243 12927789-5 2003 Pretreatment of the cells with 10nM morphine caused a transient, naloxone-reversible suppression of the appearance of activated p53 and the generation of DNA laddering.

Reactive Oxygen Species 0-23 P53 Homo sapiens 52-55 14500353-3 2003 Electrophilic prostaglandins (PGs) are known to sequester and inactivate p53 in the cytoplasm, an effect that is likely to occur when cyclooxygenase (COX)-2 levels become elevated during colon carcinogenesis. Prostaglandins 14-28 P53 Homo sapiens 73-76 12899928-0 2003 Reactive oxygen species mediate doxorubicin induced p53-independent apoptosis. Doxorubicin 32-43 P53 Homo sapiens 52-55 12927814-0 2003 Nitric oxide prevents UV-induced phosphorylation of the p53 tumor-suppressor protein at serine 46: a possible role in inhibition of apoptosis. Nitric Oxide 0-12 P53 Homo sapiens 56-59 12927814-0 2003 Nitric oxide prevents UV-induced phosphorylation of the p53 tumor-suppressor protein at serine 46: a possible role in inhibition of apoptosis. Serine 88-94 P53 Homo sapiens 56-59 12927814-1 2003 Ser-46 of p53 is phosphorylated in response to DNA-damage in vivo, and it plays a pivotal role for apoptotic signaling by p53 through regulating the transcriptional activation of genes involved in apoptosis. Serine 0-3 P53 Homo sapiens 10-13 12927814-1 2003 Ser-46 of p53 is phosphorylated in response to DNA-damage in vivo, and it plays a pivotal role for apoptotic signaling by p53 through regulating the transcriptional activation of genes involved in apoptosis. Serine 0-3 P53 Homo sapiens 122-125 12927814-5 2003 Our results suggest that NO-mediated protection of apoptosis is p53-dependent, occurring at least partly through NO-inhibition of phosphorylation of p53 on Ser-46. Serine 156-159 P53 Homo sapiens 64-67 12927814-5 2003 Our results suggest that NO-mediated protection of apoptosis is p53-dependent, occurring at least partly through NO-inhibition of phosphorylation of p53 on Ser-46. Serine 156-159 P53 Homo sapiens 149-152 14500353-14 2003 Inhibition of COX-2 by celecoxib appears to alleviate this effect on p53 by reducing electrophilic PG synthesis. Prostaglandins 99-101 P53 Homo sapiens 69-72 14500353-15 2003 Thus, COX-2 inhibition of electrophilic PG formation appears to protect p53 tumor suppressor function. Prostaglandins 40-42 P53 Homo sapiens 72-75 14500353-3 2003 Electrophilic prostaglandins (PGs) are known to sequester and inactivate p53 in the cytoplasm, an effect that is likely to occur when cyclooxygenase (COX)-2 levels become elevated during colon carcinogenesis.

Amiodarone 16-19 P53 Homo sapiens 152-156 14562283-6 2003 An immunohistochemical study of p53 expression was performed on paraffin-embedded tissue. Paraffin 64-72 P53 Homo sapiens 32-35 12871082-8 2003 Since a high amount of tumors have lost TP53 function during tumor development, the clinical application of BBI to protect normal tissue from radiation damage would effectively improve the therapeutic outcome of radiation therapy. Amiodarone 108-111 P53 Homo sapiens 40-44 12871082-11 2003 Taken together, BBI is recommended as a radioprotector for normal tissue expressing wild type TP53 during treatment of tumors characterized by a mutant TP53.

Tretinoin 18-27 P53 Homo sapiens 66-69 14693485-6 2003 Topical tretinoin therapy was found to induce a significant decrease in the expression of p53 up to 6 months of therapy followed by a significant increase after 10 months of therapy. Tretinoin 8-17 P53 Homo sapiens 90-93 12935767-8 2003 The induction and nuclear translocation of p53 by H2O2 was blocked by pyruvate and appeared to be somewhat enhanced by L-lactate or aminooxyacetate in association with oxidant generation. Hydrogen Peroxide 50-54 P53 Homo sapiens 43-46 12891704-4 2003 Ninety-seven kiloDaltons eEF2 was found to coimmunoprecipitate in a salt-stable complex with p53. Salts 68-72 P53 Homo sapiens 93-96 12935767-8 2003 The induction and nuclear translocation of p53 by H2O2 was blocked by pyruvate and appeared to be somewhat enhanced by L-lactate or aminooxyacetate in association with oxidant generation. L-lactate 119-128 P53 Homo sapiens 43-46 14555710-3 2003 Total glutathione (GSH) was significantly up-regulated (1.8- to 2.8-fold) after eGFP (but not CD80) transduction in cell lines with, but not in those lacking, functional p53. Glutathione 6-17 P53 Homo sapiens 170-173 12935767-10 2003 The pyruvate-related redox manipulation inhibited the H2O2-induced p53 activation, restored the downregulated bcl-2 and the upregulated bax, and hence enhanced the bcl-2/bax expression ratio. Hydrogen Peroxide 54-58 P53 Homo sapiens 67-70 12944468-4 2003 Here we show that the two basic amino acid groups in the p53 bipartite NLS function collaboratively to import p53. Amino Acids, Basic 26-42 P53 Homo sapiens 57-60 12944468-4 2003 Here we show that the two basic amino acid groups in the p53 bipartite NLS function collaboratively to import p53. Amino Acids, Basic 26-42 P53 Homo sapiens 110-113 14555710-3 2003 Total glutathione (GSH) was significantly up-regulated (1.8- to 2.8-fold) after eGFP (but not CD80) transduction in cell lines with, but not in those lacking, functional p53. Glutathione 19-22 P53 Homo sapiens 170-173 14555710-5 2003 Thus, oxidative stress produced by GFP selects for cells with up-regulated GSH in a p53-dependent manner, and also enhanced the cytotoxicity of anticancer drugs in neuroblastoma cell lines. Glutathione 75-78 P53 Homo sapiens 84-87 12898523-10 2003 Using specific phospho-serine antibodies, we identified phosphorylation of baculovirally expressed p53 protein at five distinct sites.

Tritium 0-7 P53 Homo sapiens 53-56 12944903-3 2003 Tritium labeling also led to nuclear accumulation of p53 and induction of the p53-regulated gene p21(WAF1) and its encoded protein (p21). Tritium 0-7 P53 Homo sapiens 78-81 12805649-12 2003 These results demonstrate that, in this cell lineage, sensitivity to oxidative DNA damage by H2O2 decreases with tumorigenicity (i.e., MCF-10A vs. MCF-10ATG3B), and show that DNA repair, altered Ras, and p53 expression, or compensatory mechanisms involving elevated antioxidant enzymes are involved in mediating these effects. Hydrogen Peroxide 93-97 P53 Homo sapiens 204-207 12810724-8 2003 PML neutralizes the inhibitory effects of Mdm2 by prolonging the stress-induced phosphorylation of p53 on serine 20, a site of the checkpoint kinase 2 (Chk2). Serine 106-112 P53 Homo sapiens 99-102 12788915-5 2003 Analysis of the transcriptional activity of the two most common p53 mutants found in human breast tumors that are associated with resistance to doxorubicin reveals that these mutations completely eliminate the ability of p53 protein to transactivate CD95 gene expression. Doxorubicin 144-155 P53 Homo sapiens 64-67 12788915-5 2003 Analysis of the transcriptional activity of the two most common p53 mutants found in human breast tumors that are associated with resistance to doxorubicin reveals that these mutations completely eliminate the ability of p53 protein to transactivate CD95 gene expression. Doxorubicin 144-155 P53 Homo sapiens 221-224 12871714-1 2003 We examined ultraviolet (UV) irradiation and cisplatin treatment damage formation and repair efficiency in the p53 tumor suppressor gene of various cultured cell lines and lymphocytes using a nonradioactive multiplex long quantitative polymerase chain reaction (QPCR) assay, which amplified a 7-kb fragment of the target gene and a 500-bp fragment of the template control to successfully increase the sensitivity and reliability of the assay. Cisplatin 45-54 P53 Homo sapiens 111-114 12871714-5 2003 The data indicated that the lesion frequency in the p53 gene was 1.27-1.75 times higher in the H23 cisplatin-sensitive cell than in the H1435 cisplatin-resistant cell at the IC(70) dose.

Tyrosine 53-56 P53 Homo sapiens 232-238 21266112-1 2003 BACKGROUND: To isolate and clone the cisplatin genes in 801-D cell line, a kind of lung cancer cell line, with the emphasis of the objective genes regulated by wild type p53 (wtp53). Cisplatin 37-46 P53 Homo sapiens 170-173 21266112-10 2003 It is possible for p53 to regulate the sensitization of lung cancer cells to cisplatin through its downstream target genes. Cisplatin 77-86 P53 Homo sapiens 19-22 12802279-5 2003 Here, we show that 2-AP suppresses p53 phosphorylation in response to gamma radiation, adriamycin, or ultraviolet treatment. Doxorubicin 87-97 P53 Homo sapiens 35-38 12810654-11 2003 The ansamycins inhibited DDP-induced activation of caspases 8 and 3 in HT29 and HCTp5.2 but not in HCT116 cells, which we postulate to be the basis for higher survival of p53-deficient cells when treated with combinations of the two drugs. Lactams, Macrocyclic 4-14 P53 Homo sapiens 171-174 12810654-11 2003 The ansamycins inhibited DDP-induced activation of caspases 8 and 3 in HT29 and HCTp5.2 but not in HCT116 cells, which we postulate to be the basis for higher survival of p53-deficient cells when treated with combinations of the two drugs. Cisplatin 25-28 P53 Homo sapiens 171-174 12802279-8 2003 Biologically, the 2-AP-mediated inhibition of p53 stabilization enables wild-type p53-containing cells to bypass adriamycin-induced G(2)/M arrest. Doxorubicin 113-123 P53 Homo sapiens 46-49 12802279-8 2003 Biologically, the 2-AP-mediated inhibition of p53 stabilization enables wild-type p53-containing cells to bypass adriamycin-induced G(2)/M arrest. Doxorubicin 113-123 P53 Homo sapiens 82-85 12771997-2 2003 Mut-p53 cells were significantly resistant to the cytotoxicity of the microtubule-targeted drugs (vinca alkaloids and taxanes), as compared with wt-p53 cells. Taxoids 118-125 P53 Homo sapiens 4-7 12654917-5 2003 Phosphorylation of p53 at serine 20, accumulation of p53 protein, transcriptional activation of p53 target genes, and cell cycle arrest and apoptotic death phenotypes were completely intact regardless of CHK2 status. Serine 26-32 P53 Homo sapiens 19-22 12782576-4 2003 In these cells, only ectopically expressed p73 activates the proapoptotic p53 target P53AIP1, whereas phosphorylation of p53 at Ser-46, shown to regulate transcriptional activation of P53AIP1, is missing. Serine 128-131 P53 Homo sapiens 121-124 12734658-4 2003 In the present study, we screened paraffin-embedded brain tissue from different areas of 18 cases (8 autopsy cases and 10 biopsies) for alterations in the TP53 and PTEN genes. Paraffin 34-42 P53 Homo sapiens 155-159 12734658-8 2003 In the second case, in tumor samples from one hemisphere, nuclear accumulation of p53 was caused by a G-->A transition in codon 244 (Gly-->Asp). Glycine 136-139 P53 Homo sapiens 82-85 12796380-0 2003 Age-associated increase of codon 72 Arginine p53 frequency in gastric cardia and non-cardia adenocarcinoma. Arginine 36-44 P53 Homo sapiens 45-48 12796380-6 2003 A significant stepwise increased frequency of codon 72 Arg p53 with age was observed in patients with gastric cancer, but not in noncancer patients (P = 0.01). Arginine 55-58 P53 Homo sapiens 59-62 12796380-8 2003 After adjustment for age and gender, a logistic regression analysis suggested that the risk for a p53 Arg homozygous patient to develop cardia cancer is 3.1 95% confidence interval, 1.4-7.3) times greater than for p53 Pro homozygous and p53 Arg/Pro heterozygous patients. Arginine 102-105 P53 Homo sapiens 98-101 12796380-8 2003 After adjustment for age and gender, a logistic regression analysis suggested that the risk for a p53 Arg homozygous patient to develop cardia cancer is 3.1 95% confidence interval, 1.4-7.3) times greater than for p53 Pro homozygous and p53 Arg/Pro heterozygous patients. Arginine 102-105 P53 Homo sapiens 214-217 12796380-8 2003 After adjustment for age and gender, a logistic regression analysis suggested that the risk for a p53 Arg homozygous patient to develop cardia cancer is 3.1 95% confidence interval, 1.4-7.3) times greater than for p53 Pro homozygous and p53 Arg/Pro heterozygous patients. Arginine 102-105 P53 Homo sapiens 214-217 12796380-8 2003 After adjustment for age and gender, a logistic regression analysis suggested that the risk for a p53 Arg homozygous patient to develop cardia cancer is 3.1 95% confidence interval, 1.4-7.3) times greater than for p53 Pro homozygous and p53 Arg/Pro heterozygous patients. Arginine 241-244 P53 Homo sapiens 98-101 12796380-10 2003 CONCLUSIONS: These findings indicate that codon 72 Arg p53 may be associated with a prolonged survival for patients who have had gastric adenocarcinoma, especially non-cardia adenocarcinoma. Arginine 51-54 P53 Homo sapiens 55-58 12796400-0 2003 Chromosomal instability rather than p53 mutation is associated with response to neoadjuvant cisplatin-based chemotherapy in gastric carcinoma. Cisplatin 92-101 P53 Homo sapiens 36-39 12743373-1 2003 Using DNA microarray and clustering of expressed genes we have analyzed the mechanism of inhibition of wild-type p53-induced apoptosis by the cytokine interleukin 6 (IL-6) and the calcium mobilizer thapsigargin (TG). Thapsigargin 198-210 P53 Homo sapiens 113-116 13678348-5 2003 Western blot analysis revealed that the time required to reach the highest level of wild-type p53 protein in B3 was longer than the time in MOLT-4 and that the p53 may be stabilized by the phosphorylation at Ser-15. Serine 208-211 P53 Homo sapiens 94-97 13678348-5 2003 Western blot analysis revealed that the time required to reach the highest level of wild-type p53 protein in B3 was longer than the time in MOLT-4 and that the p53 may be stabilized by the phosphorylation at Ser-15. Serine 208-211 P53 Homo sapiens 160-163 12776195-3 2003 By contrast, isogenic p53-null cells exposed to hypoxic conditions exhibited a 6-10-fold higher level of apoptosis, suggesting that p53 acts as a survival factor under limiting oxygen concentrations. Oxygen 177-183 P53 Homo sapiens 22-25 12776195-3 2003 By contrast, isogenic p53-null cells exposed to hypoxic conditions exhibited a 6-10-fold higher level of apoptosis, suggesting that p53 acts as a survival factor under limiting oxygen concentrations. Oxygen 177-183 P53 Homo sapiens 132-135 12776195-4 2003 Surprisingly, hypoxia-dependent growth arrest in p53(+/+) cells did not result in either p21(WAF1) or HIF-1 protein stabilization, but rather promoted a significant decrease in Ser(392)-site phosphorylation at the CK2/FACT site. Serine 177-180 P53 Homo sapiens 49-52 12776195-6 2003 In contrast to hypoxia, 5-flourouracil (5-FU)-induced p53-dependent cell death correlated with enhanced Ser(392) phosphorylation of p53 and elevated p21(WAF1) protein levels. Fluorouracil 40-44 P53 Homo sapiens 54-57 12776195-6 2003 In contrast to hypoxia, 5-flourouracil (5-FU)-induced p53-dependent cell death correlated with enhanced Ser(392) phosphorylation of p53 and elevated p21(WAF1) protein levels. Fluorouracil 40-44 P53 Homo sapiens 132-135 12776195-6 2003 In contrast to hypoxia, 5-flourouracil (5-FU)-induced p53-dependent cell death correlated with enhanced Ser(392) phosphorylation of p53 and elevated p21(WAF1) protein levels. Serine 104-107 P53 Homo sapiens 54-57 12776195-6 2003 In contrast to hypoxia, 5-flourouracil (5-FU)-induced p53-dependent cell death correlated with enhanced Ser(392) phosphorylation of p53 and elevated p21(WAF1) protein levels. Serine 104-107 P53 Homo sapiens 132-135 12776195-7 2003 Hypoxia inhibited 5-FU-induced p53-dependent cell death and attenuated p53 phosphorylation at the ATM and CK2/FACT phosphorylation sites. Fluorouracil 18-22 P53 Homo sapiens 31-34 12820963-1 2003 Under serum-free conditions, rapamycin, an inhibitor of mammalian target of rapamycin (mTOR), induces apoptosis of cells lacking functional p53. Sirolimus 29-38 P53 Homo sapiens 140-143 12743373-1 2003 Using DNA microarray and clustering of expressed genes we have analyzed the mechanism of inhibition of wild-type p53-induced apoptosis by the cytokine interleukin 6 (IL-6) and the calcium mobilizer thapsigargin (TG). Thapsigargin 212-214 P53 Homo sapiens 113-116 12753897-0 2003 Identification of two serine residues important for p53 DNA binding and protein stability. Serine 22-28 P53 Homo sapiens 52-55 12753897-3 2003 However, the substitution of the serine residues with the aspartic acid (S116/127D) abolished p53 DNA binding and led to protein stabilization. Serine 33-39 P53 Homo sapiens 94-97 12637545-8 2003 We also show that physiological targets of ATM, p53 Ser-15 and Chk2 Thr-68, were phosphorylated by Cr(VI) exposure in an ATM-dependent fashion. Serine 52-55 P53 Homo sapiens 48-51 12761496-3 2003 We demonstrated here that low doses of PTX that are unable to activate the spindle assembly checkpoint, upregulate p21 by a p53-dependent pathway and induce its translocation to the cytoplasm. Paclitaxel 39-42 P53 Homo sapiens 124-127 12771935-3 2003 Following 8 h of exposure to taxol, the cell line DoHH2 (p53 wild type) exhibited mitotic arrest and engagement of apoptosis, whereas the cell line SU-DHL-4 (p53 mutant) breached cell-cycle arrest with progression to an abnormal cycle and a 24 h delay in the engagement of apoptosis. Paclitaxel 29-34 P53 Homo sapiens 57-60 12771935-3 2003 Following 8 h of exposure to taxol, the cell line DoHH2 (p53 wild type) exhibited mitotic arrest and engagement of apoptosis, whereas the cell line SU-DHL-4 (p53 mutant) breached cell-cycle arrest with progression to an abnormal cycle and a 24 h delay in the engagement of apoptosis.

Methamphetamine 38-53 P53 Homo sapiens 77-80 12926120-4 2003 The objective response rate by cisplatin (CDDP)-based chemotherapy was significantly lower in patients with p53-positive tumors compared to those with p53-negative tumors (22% versus 59%, p = 0.0143). Cisplatin 31-40 P53 Homo sapiens 108-111 12750254-5 2003 p29ING4 and p28ING5 enhance p53 acetylation at Lys-382 residues, and physically interact with p300, a member of histone acetyl transferase complexes, and p53 in vivo. Lysine 47-50 P53 Homo sapiens 28-31 12750254-5 2003 p29ING4 and p28ING5 enhance p53 acetylation at Lys-382 residues, and physically interact with p300, a member of histone acetyl transferase complexes, and p53 in vivo. Lysine 47-50 P53 Homo sapiens 154-157 12894503-3 2003 Caffeine, a nonspecific inhibitor of ATR, enhanced the cytotoxic effect of cisplatin, modestly decreased the p53 and p21WAF-1 response to cisplatin, and affected the cdc2-p34/cyclin B1 complex by decreasing both cyclin B1 protein accumulation and cdc2-p34 tyrosine 15 phosphorylation. Cisplatin 138-147 P53 Homo sapiens 109-112 12926120-4 2003 The objective response rate by cisplatin (CDDP)-based chemotherapy was significantly lower in patients with p53-positive tumors compared to those with p53-negative tumors (22% versus 59%, p = 0.0143). Cisplatin 31-40 P53 Homo sapiens 151-154 12926120-4 2003 The objective response rate by cisplatin (CDDP)-based chemotherapy was significantly lower in patients with p53-positive tumors compared to those with p53-negative tumors (22% versus 59%, p = 0.0143). Cisplatin 42-46 P53 Homo sapiens 108-111 12926120-4 2003 The objective response rate by cisplatin (CDDP)-based chemotherapy was significantly lower in patients with p53-positive tumors compared to those with p53-negative tumors (22% versus 59%, p = 0.0143). Cisplatin 42-46 P53 Homo sapiens 151-154 12534344-6 2003 In cultured cortical neurons, we found that A beta increased p53 protein expression and phosphorylation of p53 at Ser(15). Serine 114-117 P53 Homo sapiens 107-110 12750239-10 2003 After adjustment for age, cigarette smoking, areca quid chewing, and alcohol drinking, the Gln/Gln genotype still showed an independent association with the frequency of p53 mutation (odd ratio, 4.50; 95% confidence interval, 1.52-13.36). Alcohols 69-76 P53 Homo sapiens 170-173 12944180-1 2003 Aberrant p53 protein accumulation was measured immunohistologically in 342 colorectal paraffin-embedded tissue sections from 115 patients (24 with adenocarcinoma, 59 with adenoma and 32 "hospital controls"). Paraffin 86-94 P53 Homo sapiens 9-12 12706118-5 2003 We have found up-regulated levels of the cyclin-dependent kinase 2 (cdk2) protein in HDF expressing 143(ala) mutant p53 as compared to senescent controls, together with an increase in p21-free cdk2 which, in conjunction with cyclin E, is able to form an active kinase which can phosphorylate the retinoblastoma protein. Alanine 104-107 P53 Homo sapiens 116-119 12772781-5 2003 The incidence of p53 mutation in hepatocellular cancer patients with chronic liver disease due to hepatitis B virus infection was significantly higher than in those with chronic liver disease due to alcohol, indicating that not alcohol but hepatitis B virus, in fact induces the mutations in p53 gene. Alcohols 228-235 P53 Homo sapiens 17-20 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel. Doxorubicin 180-191 P53 Homo sapiens 35-38 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel. Platinum 232-240 P53 Homo sapiens 35-38 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel. Fluorouracil 311-325 P53 Homo sapiens 35-38 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel. Taxoids 350-357 P53 Homo sapiens 35-38 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel.

Paclitaxel 38-48 P53 Homo sapiens 0-3 12715164-13 2003 CONCLUSION: The immunohistochemical detection of p53 characterizes patients with metastatic breast cancer unlikely to respond to paclitaxel. Paclitaxel 129-139 P53 Homo sapiens 49-52 12694871-0 2003 Recognition of DNA modified by antitumor cisplatin by "latent" and "active" protein p53. Cisplatin 41-50 P53 Homo sapiens 84-87 12802925-2 2003 The cell line, designated TMBL-1, carried a His-175 mutant p53. Histidine 44-47 P53 Homo sapiens 59-62 12802925-9 2003 Moreover, TMBL-1 cells are sensitive to paclitaxel, which could induce p53-independent apoptosis. Paclitaxel 40-50 P53 Homo sapiens 71-74 12698197-0 2003 Doxorubicin and vinorelbine act independently via p53 expression and p38 activation respectively in breast cancer cell lines. Doxorubicin 0-11 P53 Homo sapiens 50-53 12698197-4 2003 The aim of this study was to establish the effects of doxorubicin and vinorelbine, as single agents, in combination, and as sequential treatments, on signal transduction and p53 in the breast cancer cell lines MCF-7 and MDA-MB-468. Doxorubicin 54-65 P53 Homo sapiens 174-177 12698197-7 2003 Doxorubicin treatment resulted in increased p53 expression, without changes in MAPK or p38 activity. Doxorubicin 0-11 P53 Homo sapiens 44-47 12698197-9 2003 This additivism, where doxorubicin acts via p53 expression and vinorelbine through p38 activation, may contribute to the high clinical response rate when the two drugs are used together in the treatment of breast cancer. Doxorubicin 23-34 P53 Homo sapiens 44-47 12694301-5 2003 Radical (i.e., superoxide) (O2-) formation in response to oxLDL is associated with p53, as well as HIF-1 alpha accumulation in human macrophages, a process that is antagonized by NO. Superoxides 15-25 P53 Homo sapiens 83-86 12694301-5 2003 Radical (i.e., superoxide) (O2-) formation in response to oxLDL is associated with p53, as well as HIF-1 alpha accumulation in human macrophages, a process that is antagonized by NO. Superoxides 28-30 P53 Homo sapiens 83-86 12684648-2 2003 A sequence polymorphism at codon 72 of the p53 gene results in either a proline or an arginine and may induce different functional activities. Arginine 86-94 P53 Homo sapiens 43-46 12684648-4 2003 It has been reported that the p53 Arg homozygous genotype could be a potential genetic risk factor for cancer. Arginine 34-37 P53 Homo sapiens 30-33 12684648-8 2003 A significantly higher prevalence of homozygosity for the p53 Arg allele was observed in the patients as compared to the controls. Arginine 62-65 P53 Homo sapiens 58-61 12534345-9 2003 These results provide novel information on the functional interplay between CTF2 and p53/p73 as important determinants of their function in cell proliferation, apoptosis, DNA repair and cisplatin resistance. Cisplatin 186-195 P53 Homo sapiens 85-88 12702563-7 2003 Both microPET imaging and biodistribution studies showed time- and dose-dependent increases in accumulation of the reporter substrate 9-(4-[(18)F]-fluoro-3-hydroxymethylbutyl)guanine only in p53-TAg tumors. 9-(4-fluoro-3-hydroxymethylbutyl)guanine 134-182 P53 Homo sapiens 191-194 12702572-8 2003 Instead, morphine caused an NH(2)-terminal phosphorylation of p53 at Ser(9) and/or Ser(15) and a stabilization of p53 in MCF-7 cells that express wild-type p53. Morphine 9-17 P53 Homo sapiens 62-65 12702572-8 2003 Instead, morphine caused an NH(2)-terminal phosphorylation of p53 at Ser(9) and/or Ser(15) and a stabilization of p53 in MCF-7 cells that express wild-type p53. Morphine 9-17 P53 Homo sapiens 114-117 12702572-8 2003 Instead, morphine caused an NH(2)-terminal phosphorylation of p53 at Ser(9) and/or Ser(15) and a stabilization of p53 in MCF-7 cells that express wild-type p53. Morphine 9-17 P53 Homo sapiens 114-117 12702572-8 2003 Instead, morphine caused an NH(2)-terminal phosphorylation of p53 at Ser(9) and/or Ser(15) and a stabilization of p53 in MCF-7 cells that express wild-type p53. Serine 69-72 P53 Homo sapiens 62-65 12702572-14 2003 Our results suggest that morphine, alone or in combination with Nx, may reduce the growth of certain tumors, apparently in part through activation of p53. Morphine 25-33 P53 Homo sapiens 150-153 12694871-4 2003 Binding of active, latent, and in vitro-activated p53 protein to DNA fragments modified by antitumor cisplatin was studied using electrophoretic mobility shift assay in agarose gels and immunoblotting analysis. Cisplatin 101-110 P53 Homo sapiens 50-53 12694871-5 2003 We found that both latent and active p53 forms bound to random sequences of DNA globally modified by cisplatin with a higher affinity than to unmodified DNA. Cisplatin 101-110 P53 Homo sapiens 37-40 12694871-8 2003 Competition experiments involving a 20-bp consensus sequence of p53 suggested that the p53 core domain was a primary binding site of the active p53 when it bound to DNA fragments lacking consensus sequence, but modified by cisplatin. Cisplatin 223-232 P53 Homo sapiens 64-67 12694871-8 2003 Competition experiments involving a 20-bp consensus sequence of p53 suggested that the p53 core domain was a primary binding site of the active p53 when it bound to DNA fragments lacking consensus sequence, but modified by cisplatin. Cisplatin 223-232 P53 Homo sapiens 87-90 12694871-8 2003 Competition experiments involving a 20-bp consensus sequence of p53 suggested that the p53 core domain was a primary binding site of the active p53 when it bound to DNA fragments lacking consensus sequence, but modified by cisplatin. Cisplatin 223-232 P53 Homo sapiens 87-90 12659830-1 2003 PRPK (p53-related protein kinase) has been reported as a novel protein kinase which binds to the tumor suppressor protein p53 and induces phosphorylation of p53 at Ser 15. Serine 164-167 P53 Homo sapiens 6-9 12687016-2 2003 Our previous study showed that the antitumor activity of resveratrol occurs through mitogen-activated protein kinases-mediated p53 activation and induction of apoptosis. Resveratrol 57-68 P53 Homo sapiens 127-130 12499368-2 2003 Phosphorylation at the CHK2 site (Ser(20)) in the N-terminal activation domain of p53 stabilized p300 binding. Serine 34-37 P53 Homo sapiens 82-85 12499368-8 2003 The phosphopeptide binding activity of p300 is critical for DNA-dependent acetylation, as p53 acetylation was inhibited by phospho-Ser(20) peptides. Serine 131-134 P53 Homo sapiens 90-93 12659830-1 2003 PRPK (p53-related protein kinase) has been reported as a novel protein kinase which binds to the tumor suppressor protein p53 and induces phosphorylation of p53 at Ser 15. Serine 164-167 P53 Homo sapiens 122-125 12628744-3 2003 Here we show that, in neuronal cells, divergent cellular insults, i.e. the exposure to glutamate, beta-amyloid (Abeta) or H(2)O(2), may converge to a common pathway that initiate with elevation of p53 protein levels. Glutamic Acid 87-96 P53 Homo sapiens 197-200 12501250-3 2003 Because Tat has been shown to interact with histone acetyltransferase domains of p300/cAMP-responsive element-binding protein (CREB)-binding protein and p300/CREB-binding protein-associated factor, we have investigated whether Tat might alter p53 acetylation and tumor suppressor-responsive transcription. Cyclic AMP 86-90 P53 Homo sapiens 243-246 12501250-5 2003 Further, p53 trans-activation of the 14-3-3varsigma promoter was markedly repressed by Tat-histone acetyltransferase interactions, and p53 acetylation by p300/CREB-binding protein-associated factor on residue Lys(320) was diminished as a result of Tat-histone acetyltransferase binding in vivo and in vitro.

Threonine 149-152 P53 Homo sapiens 142-145 12606123-3 2003 Furthermore, p53 phosphorylation at serine 15 is delayed or diminished in Msh2-deficient cells, suggesting that Msh2 may act upstream of p53 in a post-UVB apoptosis or growth arrest response pathway. Serine 36-42 P53 Homo sapiens 13-16 12606123-3 2003 Furthermore, p53 phosphorylation at serine 15 is delayed or diminished in Msh2-deficient cells, suggesting that Msh2 may act upstream of p53 in a post-UVB apoptosis or growth arrest response pathway.

Aminothiol 40-50 P53 Homo sapiens 14-17 12663048-4 2003 Here, we demonstrated that p53 accumulation by WR1065 in MCF-7 cells did not result from the formation of DNA-damage as measured by DNA fragmentation and Comet assay, nor from oxidative stress as detected by measurement of glutathione levels, lipid peroxidation and reactive oxygen species production. Glutathione 223-234 P53 Homo sapiens 27-30 12663048-4 2003 Here, we demonstrated that p53 accumulation by WR1065 in MCF-7 cells did not result from the formation of DNA-damage as measured by DNA fragmentation and Comet assay, nor from oxidative stress as detected by measurement of glutathione levels, lipid peroxidation and reactive oxygen species production.

Paclitaxel 106-111 P53 Homo sapiens 54-57 26680929-2 2003 In this study, to further demonstrate the differential effect of the tumor suppressor gene, p53, on the Taxol-induced apoptosis in osteogenic sarcoma cell lines, we used p53-defected SaOS2 cells and wild type p53-expressed U2OS cells. Paclitaxel 104-109 P53 Homo sapiens 92-95 26680929-4 2003 To examine whether the differential expressions of p53, in U2OS and SaOS2 cells, were associated with Taxol-induced apoptosis, DNA fragmentation assays were performed on both cytosolic and genomic DNA.

Serine 6-13 P53 Homo sapiens 17-20 26680929-6 2003 RESULTS: The cell viability of the p53-defected SaOS2 cells was markedly decreased with Taxol treatment. Paclitaxel 88-93 P53 Homo sapiens 35-38 26680929-10 2003 The Taxol-induced apoptosis in p53 defected-osteogenic sarcoma cells was associated with the PARP cleavage as a result of the increased activity of caspase 3, and the high expressions of cyclin B1 and PLK. Paclitaxel 4-9 P53 Homo sapiens 31-34 12684432-0 2003 Low-dose fractionated radiation potentiates the effects of Paclitaxel in wild-type and mutant p53 head and neck tumor cell lines.

Tamoxifen 86-95 P53 Homo sapiens 48-52 12684392-5 2003 RESULTS: In univariate analysis, both TP53 gene mutation (28% of the tumors) and a VEGF level above the median value were significantly associated with a short progression-free survival, post-relapse overall survival, and a poor rate of response to tamoxifen. Tamoxifen 249-258 P53 Homo sapiens 38-42 12684392-6 2003 In Cox multivariate regression analysis including the traditional predictive factors, the addition of TP53 gene mutation and VEGF status, alone or in combination, significantly predicted a poor efficacy of tamoxifen treatment. Tamoxifen 206-215 P53 Homo sapiens 102-106 12684392-9 2003 CONCLUSIONS: Combined TP53 gene mutation status and high VEGF levels of ER-positive primary breast tumors independently predict a poor course of the disease of patients with advanced breast cancer treated with tamoxifen. Tamoxifen 210-219 P53 Homo sapiens 22-26 12841678-7 2003 p53 protein accumulation was determined by immunohistochemistry on paraffin-embedded tumor specimens from 58/71 samples available for this study. Paraffin 67-75 P53 Homo sapiens 0-3 12640128-8 2003 We found that centrosomal p53 is poly(ADP-ribosyl)ated in vivo and centrosomal PARP-1 directly catalyzes poly(ADP-ribosyl)ation of p53 in vitro.

Cisplatin 144-153 P53 Homo sapiens 46-49 12668287-13 2003 Therefore, detection of p53 overexpression using the DO7 antibody may be considered as a predictive marker of chemoresistance for cisplatin in patients with ovarian carcinoma.

Doxorubicin 88-99 P53 Homo sapiens 15-18 12615724-5 2003 However, in contrast to p53 wild-type epithelium, estrogen and progesterone, singly or in combination, strongly enhance tumorigenesis in p53-null mammary epithelium. Progesterone 63-75 P53 Homo sapiens 137-140 12695658-0 2003 There"s NO business like p53 business: nitric oxide regulates phosphorylation of p53 in chronic inflammatory disease.

Paclitaxel 190-200 P53 Homo sapiens 12-15 12214265-2 2002 However, DOX still protects a subset of tumor cell lines lacking wt p53 (HL60 and Jurkat leukemia cells), thus limiting the utility of protection of cells with wt p53 (e.g., normal cells). Doxorubicin 9-12 P53 Homo sapiens 68-71 12101184-0 2002 Adriamycin-induced senescence in breast tumor cells involves functional p53 and telomere dysfunction.

Doxorubicin 25-35 P53 Homo sapiens 61-64 12101184-4 2002 Inactivation of wild-type p53 resulted in a transition of the cellular response to adriamycin treatment from replicative senescence to delayed apoptosis, demonstrating that p53 plays an integral role in the fate of breast tumor cells treated with DNA-damaging agents. Doxorubicin 83-93 P53 Homo sapiens 26-29 12101184-4 2002 Inactivation of wild-type p53 resulted in a transition of the cellular response to adriamycin treatment from replicative senescence to delayed apoptosis, demonstrating that p53 plays an integral role in the fate of breast tumor cells treated with DNA-damaging agents. Doxorubicin 83-93 P53 Homo sapiens 173-176 12101184-8 2002 To our knowledge, these data are the first to demonstrate that the mechanism of adriamycin-induced senescence is dependent on both functional p53 and telomere dysfunction rather than overall shortening.

Doxorubicin 107-118 P53 Homo sapiens 12-15 12214265-3 2002 The present work overcomes this obstacle by adding an abrogator of p53-independent checkpoint (e.g., UCN-01) to the DOX-PTX sequence. Doxorubicin 116-119 P53 Homo sapiens 67-70 12214265-4 2002 By inhibiting a p53-independent pathway, UCN-01 overrode DOX-induced G2 arrest and instead induced G1 arrest in HL60 and Jurkat, thus propelling these p53-deficient cells from G2 to G1.

Adenosine Monophosphate 12-15 P53 Homo sapiens 79-82 12203114-4 2002 Whereas induction of Hi95 by prolonged hypoxia or by oxidative stress is most likely p53-independent, its induction in response to DNA damaging treatments (gamma- or UV-irradiation, or doxorubicin) occurs in a p53-dependent manner. Doxorubicin 185-196 P53 Homo sapiens 210-213 12500660-3 2002 DNA breaks in p53 gene produced by restriction endonuclease AfaI were detected by using this new method followed by Southern hybridization with DIG-labeled probe. digitoxose 144-147 P53 Homo sapiens 14-17 12175696-1 2002 The correlation between inactivation of the TP53 gene through mutation or the presence of high-risk human papillomavirus (HPV) DNA and intrinsic paclitaxel sensitivity was studied in 27 gynaecological cancer cell lines.

Estradiol 83-92 P53 Homo sapiens 13-16 12459315-3 2002 The aim of this study was to evaluate the effect of low and high doses of estradiol in p53 gene expression in epithelial cancer-derived cell lines from the reproductive tract. Estradiol 74-83 P53 Homo sapiens 87-90 12459315-4 2002 METHODS: p53 gene expression was assessed by Northern and Western blot methods in three human epithelial cancer-derived cell lines after estradiol treatment. Estradiol 137-146 P53 Homo sapiens 9-12 12459315-6 2002 p53 protein content was nearly constant in HeLa and C-33 cell lines at administration of 10 nM of estradiol. Estradiol 98-107 P53 Homo sapiens 0-3 12459315-7 2002 However, when estradiol was administered at a higher dose (1 micro M), an increase in p53 protein was observed over time in HeLa and CaLo cell lines. Estradiol 14-23 P53 Homo sapiens 86-89 12459315-9 2002 CONCLUSIONS: Overall results indicate that estradiol induces variations of p53 protein levels in epithelial cancer-derived cell lines from the reproductive tract in vitro and that this effect may be related with status p53 and/or presence of E6/E7 from human papillomavirus.

Glutathione 93-96 P53 Homo sapiens 42-45 21329584-6 2002 The expression of p53, Fas and Bax genes in Tanshinone group was up-regulated markedly, but Bcl-2 was obviously down-regulated. tanshinone 44-54 P53 Homo sapiens 18-21 12160929-10 2002 These data suggest that, in human lung cancer cells, GSH plays a vital role in the protection of TCE- and PERC-induced oxidative stress and apoptosis, which may be mediated through a p53-dependent pathway. Glutathione 53-56 P53 Homo sapiens 183-186 12387362-0 2002 Abeta[25-35] peptide and iron promote apoptosis in lymphocytes by an oxidative stress mechanism: involvement of H2O2, caspase-3, NF-kappaB, p53 and c-Jun. Iron 25-29 P53 Homo sapiens 140-143 12080066-5 2002 Moreover, full-length p53 and a C-terminal polypeptide (residues 373-383) inhibit the BLM and WRN helicase activities, but phosphorylation at Ser(376) or Ser(378) completely abolishes this inhibition. Serine 142-145 P53 Homo sapiens 22-25 12080066-6 2002 Following blockage of DNA replication, Ser(15) phospho-p53, BLM, and RAD51 colocalize in nuclear foci at sites likely to contain DNA replication intermediates in cells. Serine 39-42 P53 Homo sapiens 55-58 12175902-3 2002 The results show that the removal of anti-BPDE DNA adducts from the genome overall and NTS by GGR was significantly reduced in HPV-16E6 protein expressing cells as compared to that in normal and HPV-16E7 protein expressing cells, indicating the role of p53 and not pRb in nucleotide excision repair (NER). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 42-46 P53 Homo sapiens 253-256 12160929-4 2002 The results showed that exposure to vapor TCE and PERC produced a dose-dependent and more pronounced accumulation of H(2)O(2) in p53-WT H460 than p53-null H1299 cells. Hydrogen Peroxide 117-125 P53 Homo sapiens 129-132 12160929-5 2002 The accumulation of H(2)O(2) was accompanied by severe cellular damage, as indicated by the significant increase of lipid peroxidation and apoptosis in p53-WT H460 cells, but not p53-null H1299 cells. Hydrogen Peroxide 20-28 P53 Homo sapiens 152-155 12160929-7 2002 In contrast, depletion of GSH in p53-null H1299 cells enhanced TCE- or PERC-induced lipid peroxidation.

Serine 51-54 P53 Homo sapiens 207-210 11925449-7 2002 Introducing an Ala(19) mutation into the p53(F270A) protein abolished both RNA.MDM2 complex binding and hyper-ubiquitination in vivo, thus indicating that p53(F270A) protein hyper-ubiquitination depends upon MDM2 binding to its primary site in the BOX-I domain. Alanine 15-18 P53 Homo sapiens 41-46 11925449-7 2002 Introducing an Ala(19) mutation into the p53(F270A) protein abolished both RNA.MDM2 complex binding and hyper-ubiquitination in vivo, thus indicating that p53(F270A) protein hyper-ubiquitination depends upon MDM2 binding to its primary site in the BOX-I domain.

Zinc 10-16 P53 Homo sapiens 111-114 12107071-6 2002 Reducing [Zn(2+)](i), using N,N,N",N"-tetrakis(2-pyridylmethyl)ethylenediamine, caused rapid apoptosis in both p53(wt) and p53(mut) cells, although cotreatment with VP-16 exacerbated apoptosis only in p53(wt) cells. Zinc 10-16 P53 Homo sapiens 123-126 12107071-6 2002 Reducing [Zn(2+)](i), using N,N,N",N"-tetrakis(2-pyridylmethyl)ethylenediamine, caused rapid apoptosis in both p53(wt) and p53(mut) cells, although cotreatment with VP-16 exacerbated apoptosis only in p53(wt) cells. Zinc 10-16 P53 Homo sapiens 123-126 12107071-8 2002 We conclude that the DNA damage-induced transient is p53-independent up to a damage threshold, beyond which competent cells reduce [Zn(2+)](i) before apoptosis. Zinc 132-138 P53 Homo sapiens 53-56 12107071-9 2002 Early stress responses in p53(wt) cells take place in an environment of enhanced Zn(2+) availability.

Copper 0-6 P53 Homo sapiens 107-110 11964141-8 2002 Our results show that a low level of copper accumulation in the range of 25-40 microg/g of cellular protein increases the steady-state levels of p53. Copper 37-43 P53 Homo sapiens 145-148 11964141-9 2002 At copper accumulation levels higher than 60 microg/g of cellular protein, p53 is oxidized. Copper 3-9 P53 Homo sapiens 75-78 11964141-10 2002 These results suggest that p53 is vulnerable to free radical-mediated oxidation at cysteine residues. Cysteine 83-91 P53 Homo sapiens 27-30 12067581-9 2002 Similarly, the disruption of correct p53 folding and DNA binding by Cd(II), Ni(II) and Co(II) has been shown by other authors.

Resveratrol 0-11 P53 Homo sapiens 75-78 12390773-4 2002 RESULT: NADH not only inhibited the apoptosis induced by UVB irradiation, but also up-regulated the expression of Bcl-2 protein and down-regulated expressions of p53 and Bax proteins (P<0.01). NAD 8-12 P53 Homo sapiens 162-165 12390773-6 2002 CONCLUSION: NADH significantly inhibits apoptosis induced by UVB irradiation possibly by the mechanism of up-regulating Bcl-2 expression and down-regulating p53 and Bax expressions. NAD 12-16 P53 Homo sapiens 157-160 11914922-2 2002 This study describes the induction of ELCS in p53 mutated Burkitt"s lymphoma cell lines after treatment with irradiation or the microtubule inhibitor, SK&F 96365.

Arginine 150-153 P53 Homo sapiens 166-169 11857392-7 2002 TP53 mutations, mainly transversions, were more frequently found in heavy smokers (p = 0.03), with the same tendency after chronic alcohol consumption. Alcohols 131-138 P53 Homo sapiens 0-4 11857452-13 2002 Heat shock causes phosphorylation of p53 at Serine-15, but there is no correlation between phosphorylation at this site and activation of the protein. Serine 44-50 P53 Homo sapiens 37-40 11935300-6 2002 RESULTS: Ex vivo chemosensitivity testing showed that tumors with p53 mutations were significantly more resistant to the cyclophosphamide/etoposide/epirubicin regimen than with normal p53 gene ( P = 0.012).

Oligonucleotides 91-107 P53 Homo sapiens 77-80 11889192-4 2002 Addition of pifithrin-alpha, a specific inhibitor of p53, or transfection of p53 antisense oligonucleotides caused decreased RV-induced p53 and p21 expression in PTC and FTC cells. Oligonucleotides 91-107 P53 Homo sapiens 77-80 11865061-1 2002 Previous studies have demonstrated that phosphorylation of human p53 on serine 15 contributes to protein stabilization after DNA damage and that this is mediated by the ATM family of kinases. Serine 72-78 P53 Homo sapiens 65-68 12071473-7 2002 The expression of p53 and p21WAF1 proteins significantly increased after 24 or 48 hr of incubation with either melatonin or D3. Melatonin 111-120 P53 Homo sapiens 18-21 12071473-9 2002 These data support the hypothesis that melatonin reduces MCF-7 cell proliferation by modulating cell-cycle length through the control of the p53-p21 pathway, but without clearly inducing apoptosis. Melatonin 39-48 P53 Homo sapiens 141-144 11870884-0 2002 Restoration of wild-type conformation and activity of a temperature-sensitive mutant of p53 (p53(V272M)) by the cytoprotective aminothiol WR1065 in the esophageal cancer cell line TE-1. Aminothiol 127-137 P53 Homo sapiens 88-91 11865061-2 2002 However, cellular exposure to hypoxia does not induce any detectable level of DNA lesions compared to ionizing radiation, and the oxygen dependency of p53 protein accumulation differs from that of HIF-1, the hypoxia-inducible transcription factor. Oxygen 130-136 P53 Homo sapiens 151-154 11870884-0 2002 Restoration of wild-type conformation and activity of a temperature-sensitive mutant of p53 (p53(V272M)) by the cytoprotective aminothiol WR1065 in the esophageal cancer cell line TE-1.

Serine 61-67 P53 Homo sapiens 54-57 11896587-2 2002 Serine 20 phosphorylation of p53 has been shown to be required for the activation of p53 following UV radiation, but the signaling pathway mediating UV-induced phosphorylation is unknown. Serine 0-6 P53 Homo sapiens 29-32 11896587-2 2002 Serine 20 phosphorylation of p53 has been shown to be required for the activation of p53 following UV radiation, but the signaling pathway mediating UV-induced phosphorylation is unknown. Serine 0-6 P53 Homo sapiens 85-88 11896587-3 2002 Here, we determined the role of MAP kinases in UVB-induced phosphorylation and found that JNKs are directly involved in the phosphorylation of p53 at serine 20. Serine 150-156 P53 Homo sapiens 143-146 11896587-4 2002 In a mouse JB6 epidermal cell line, dominant negative JNK1 abrogated UVB-induced phosphorylation of p53 at serine 20, whereas dominant negative p38 kinase or its inhibitor, SB202190, partially attenuated the phosphorylation. Serine 107-113 P53 Homo sapiens 100-103 11880544-3 2002 Moreover, p53 also participates in base excision repair of hydrogen peroxide-induced damage, still at an early stage of investigation. Hydrogen Peroxide 59-76 P53 Homo sapiens 10-13 11896587-6 2002 Importantly, UVB-activated or active recombinant JNK1/2, or the p38 kinase downstream target, MAPKAPK-2, but not ERKs or p38 kinase, phosphorylated p53 at serine 20 in vitro. Serine 155-161 P53 Homo sapiens 148-151 11896587-7 2002 Furthermore, phosphorylation of p53 at serine 20 by UVB-activated JNKs and UVB-induced p53-dependent transcriptional activity were suppressed in Jnk1 or Jnk2 knockout (Jnk1(-/-) or Jnk2(-/-)) cells. Serine 39-45 P53 Homo sapiens 32-35 11896587-9 2002 These findings strongly suggest that JNKs are the major direct signaling mediators of UVB-induced p53 phosphorylation at serine 20. Serine 121-127 P53 Homo sapiens 98-101 11991255-3 2002 In Hep3B cells, apoptosis induced by cisplatin was p53-independent, and was associated with up-regulation of cell cycle regulators, pro-apoptotic genes, growth receptors, and genes involved in signal transduction. Cisplatin 37-46 P53 Homo sapiens 51-54 21315017-1 2002 BACKGROUND: To study the effects of extraneous p53 antisense RNA on malignant growth and sensitivity to cisplatin of human lung cancer cell line. Cisplatin 104-113 P53 Homo sapiens 47-50 21315017-13 2002 The sensitivity of PEGFP-p53(AS)-801D cells to cisplatin was increased. Cisplatin 47-56 P53 Homo sapiens 25-28 21315017-15 2002 CONCLUSIONS: p53 mutation at 248 code plays an important role on malignant growth and resistance to cisplatin of human lung cancer cell line 801D. Cisplatin 100-109 P53 Homo sapiens 13-16 21315017-16 2002 Malignant growth of cells with p53 deletion and mutation at 248 codon can be inhibited by extraneous p53 antisense RNA, and simultaneously the sensitivity to cisplatin is also increased. Cisplatin 158-167 P53 Homo sapiens 31-34 11850850-5 2002 On the other hand upon serum stimulation, when Akt becomes active and enhances cell survival, phosphorylation occurs at an Akt consensus site (serine 166) within the Mdm2 protein, a key regulator of p53 function. Serine 143-149 P53 Homo sapiens 199-202 11822871-5 2002 Moreover, expression of functional p53 protein using a temperature-sensitive human p53val(138) induced ceramide generation by activation of neutral SMase but not acid SMase through ROS formation.

Serine 67-73 P53 Homo sapiens 116-119 11861384-5 2002 Because phosphorylation of p53 at serines 15, 20, and 392 may play a role in regulating p53-mediated apoptotic activity, we determined the phosphorylation status of exogenous p53 in mutant and wild-type gliomas after Ad-p53 transfer. Serine 34-41 P53 Homo sapiens 27-30 11861384-10 2002 When wild-type p53 glioma cells were exposed to radiation after Ad-p53 infection, phospho-Ser15-p53 and phospho-Ser20-p53 were detected at high levels, and the cells subsequently underwent apoptosis; no change in serine 392 was detected. Serine 213-219 P53 Homo sapiens 15-18 11861384-11 2002 The induction of apoptosis and the expression of phospho-Ser15 and phospho-Ser20 in these cells were also enhanced by the combination of Ad-p53 and other DNA-damaging agents such as cisplatin and bichloroethyl nitrosourea. Cisplatin 182-191 P53 Homo sapiens 140-143 11852106-0 2002 Curcumin induces apoptosis in human breast cancer cells through p53-dependent Bax induction. Curcumin 0-8 P53 Homo sapiens 64-67 11852106-2 2002 From quantitative image analysis data showing an increase in the percentage of cells with a sub-G0/G1 DNA content, we demonstrated curcumin-induced apoptosis in the breast cancer cell line MCF-7, in which expression of wild-type p53 could be induced. Curcumin 131-139 P53 Homo sapiens 229-232 11852106-4 2002 Further experiments using p53-null MDAH041 cell as well as low and high p53-expressing TR9-7 cell, in which p53 expression is under tight control of tetracycline, established that curcumin induced apoptosis in tumor cells via a p53-dependent pathway in which Bax is the downstream effector of p53.

Glycine 58-61 P53 Homo sapiens 11-14 11711532-3 2002 ATR has been shown to phosphorylate p53 at Ser(15), and this damage-induced phosphorylation is diminished by expression of a catalytically inactive (ATR-kd) mutant. Serine 43-46 P53 Homo sapiens 36-39 11711532-6 2002 Indeed, ATR-kd expression sensitized these cells to DNA damage and caused a transient decrease in damage-induced serine 15 phosphorylation of p53.

Heparin 12-19 P53 Homo sapiens 119-122 11866879-11 2002 CONCLUSION: Heparin and ADM appear to interact in a synergistic manner, which may be related to the over-expression of p53 and p21 mRNA and the elevated ratio of Bax/Bcl-2 mRNA. Doxorubicin 24-27 P53 Homo sapiens 119-122 11885700-3 2002 We showed that VCA induced apoptosis in both SK-Hep-1 (p53-positive) and Hep 3B (p53-negative) cells through p53- and p21-independent pathways. cis-vaccenic acid 15-18 P53 Homo sapiens 81-84 11885700-3 2002 We showed that VCA induced apoptosis in both SK-Hep-1 (p53-positive) and Hep 3B (p53-negative) cells through p53- and p21-independent pathways. cis-vaccenic acid 15-18 P53 Homo sapiens 81-84 11841447-7 2002 We found that the expression of the cell cycle checkpoint protein Chk1 was reduced in the etoposide-treated p53-transfected cells by 24 h, and this correlated with a reduction in the extent of etoposide-induced phosphorylation of CDK1 at tyrosine 15 (Y15). Tyrosine 238-246 P53 Homo sapiens 108-111 11841447-5 2002 p53-transfected and control cells were treated with etoposide and trapped at mitosis with nocodazole. Nocodazole 90-100 P53 Homo sapiens 0-3 11862428-5 2002 Functionality of the p53 pathway was evaluated by incubating cells with carboplatin or doxorubicin and monitoring the effects on the levels of the p53, p21(WAF1/CIP1), and MDM 2 proteins by Western blot analyses.

Paraffin 62-70 P53 Homo sapiens 0-3 11864911-1 2002 We have investigated the mechanism of S-phase arrest elicited by the carcinogen benzo(a)pyrene dihydrodiol epoxide (BPDE) in p53-deficient cells. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 116-120 P53 Homo sapiens 125-128 11802206-0 2002 P53 overexpression predicts poor chemosensitivity to high-dose 5-fluorouracil plus leucovorin chemotherapy for stage IV colorectal cancers after palliative bowel resection. Fluorouracil 63-77 P53 Homo sapiens 0-3 11812076-10 2002 The present in vitro study showed that wild-type p53 gene transduction significantly enhanced sensitivity to CDDP and the apoptotic index in HRA cells. Cisplatin 109-113 P53 Homo sapiens 49-52 11809417-0 2002 p53 dependent apoptosis in glioma cell lines in response to hydrogen peroxide induced oxidative stress. Hydrogen Peroxide 60-77 P53 Homo sapiens 0-3 11809417-3 2002 The role of p53 in ROS induced cell death has not been consistent and has been shown to be cell type dependent. Reactive Oxygen Species 19-22 P53 Homo sapiens 12-15 11809417-8 2002 H(2)O(2) induced cell death was significantly reduced by antisense p53 oligonucleotide.

Hydrogen Peroxide 73-81 P53 Homo sapiens 37-40 11836677-4 2002 Subjects homozygous for the p53 Pro allele had a more than 2-fold increased risk of developing ESCC (OR=2.18; 95%CI=1.10-4.35, adjusted for age, sex, and smoking), whereas the Arg/Pro genotype was not associated with elevated risk of the cancer (adjusted OR=0.84; 95%CI=0.42-1.68). Arginine 176-179 P53 Homo sapiens 28-31 11850804-2 2002 We have previously shown that estradiol (E(2)) treatment of T47D cells causes an increase in the level of p53 and a concomitant phosphorylation of retinoblastoma protein (pRb). Estradiol 30-39 P53 Homo sapiens 106-109 11798189-0 2002 p53 inhibits adriamycin-induced down-regulation of cyclin D1 expression in human cancer cells. Doxorubicin 13-23 P53 Homo sapiens 0-3 11798189-4 2002 Here we show that infection with an adenovirus vector expressing the wild-type p53 gene (Ad-p53) caused an increase in cyclin D1 protein levels in human colorectal cancer cell lines DLD-1 and SW620; treatment with the anti-cancer drug adriamycin, however, down-regulated their cyclin D1 protein expression in a dose-dependent manner. Doxorubicin 235-245 P53 Homo sapiens 79-82 11798189-4 2002 Here we show that infection with an adenovirus vector expressing the wild-type p53 gene (Ad-p53) caused an increase in cyclin D1 protein levels in human colorectal cancer cell lines DLD-1 and SW620; treatment with the anti-cancer drug adriamycin, however, down-regulated their cyclin D1 protein expression in a dose-dependent manner. Doxorubicin 235-245 P53 Homo sapiens 92-95 11798189-5 2002 The suppression of cyclin D1 expression following adriamycin treatment could be blocked by simultaneous Ad-p53 infection. Doxorubicin 50-60 P53 Homo sapiens 107-110 11706017-6 2002 MC also activated p38 mitogen-activated protein kinase (MAPK) at 16-24 h. Accumulation of p53 and p53 phosphorylated at serine 15 was not changed by SB203580, a specific inhibitor of p38 MAPK or overexpression of a dominant negative mutant of p38 MAPK at 8 h after MC treatment, whereas the accumulation was suppressed at 24 h. These results suggest that MC induces accumulation and phosphorylation of p53 via a p38 MAPK-independent (early) and p38 MAPK-dependent (late) pathway.

Serine 34-37 P53 Homo sapiens 56-59 11707453-6 2002 Analysis of p53-dependent transcription following UV revealed that the phosphorylation of threonine 18 is required for transactivation of the p21, Hdm2 (the human ortholog of Mdm2), and GADD45 genes. Threonine 90-99 P53 Homo sapiens 12-15 12197224-4 2002 We hypothesized that tumors staining for p53 would be resistant to cisplatin. Cisplatin 67-76 P53 Homo sapiens 41-44 11734332-4 2002 Antiproliferative activity of betulinic acid was related to a cytotoxic effect on two p53 wild-type and on one p53 mutant cell lines and to a cytostatic effect on one p53 mutant melanoma clone. betulinic acid 30-44 P53 Homo sapiens 86-89 11734332-4 2002 Antiproliferative activity of betulinic acid was related to a cytotoxic effect on two p53 wild-type and on one p53 mutant cell lines and to a cytostatic effect on one p53 mutant melanoma clone. betulinic acid 30-44 P53 Homo sapiens 111-114 11734332-4 2002 Antiproliferative activity of betulinic acid was related to a cytotoxic effect on two p53 wild-type and on one p53 mutant cell lines and to a cytostatic effect on one p53 mutant melanoma clone. betulinic acid 30-44 P53 Homo sapiens 111-114 11734333-5 2002 Low-dose cisplatin induced a transient G(1) arrest, S phase block and upregulation of p53 and p21(WAF1/CIP1) expression in HepG2, but not in Hep3B cells. Cisplatin 9-18 P53 Homo sapiens 86-89 11734333-7 2002 In HepG2, upregulation of p53 and p21(WAF1/CIP1) was observed before apoptosis occurred, suggesting that cisplatin-induced apoptosis in HepG2 might be p53-dependent. Cisplatin 105-114 P53 Homo sapiens 26-29 11734333-7 2002 In HepG2, upregulation of p53 and p21(WAF1/CIP1) was observed before apoptosis occurred, suggesting that cisplatin-induced apoptosis in HepG2 might be p53-dependent. Cisplatin 105-114 P53 Homo sapiens 151-154 11734333-10 2002 In conclusion, cisplatin induced apoptosis in hepatoma cells via both p53-dependent and -independent pathways. Cisplatin 15-24 P53 Homo sapiens 70-73 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Doxorubicin 142-152 P53 Homo sapiens 32-35 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Doxorubicin 142-152 P53 Homo sapiens 237-240 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Doxorubicin 142-152 P53 Homo sapiens 237-240 11791172-6 2002 Our results with 5-FU thus show that genetically separable functions of p53 are involved in its ability to respond to DNA-damaging agents to induce apoptosis. Fluorouracil 17-21 P53 Homo sapiens 72-75 12017271-4 2002 Synergistic effects on p53 and p21 levels between the oligonucleotide and chemotherapeutic agents were also observed in vitro. Oligonucleotides 54-69 P53 Homo sapiens 23-26 11782367-6 2002 Conversely, treatment with the B[a]P metabolite 7r,8t-dihydroxy-9t,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE) repressed BRCA-1 promoter activity and protein, while increasing p53 and p21 protein levels. 7r,8t-dihydroxy-9t,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene 48-109 P53 Homo sapiens 182-185 11782367-7 2002 Transient expression of dominant-negative p53 ((175)Arg-->His) counteracted the detrimental effects of BPDE on BRCA-1 promoter activity and protein levels. Arginine 52-55 P53 Homo sapiens 42-45 11782367-7 2002 Transient expression of dominant-negative p53 ((175)Arg-->His) counteracted the detrimental effects of BPDE on BRCA-1 promoter activity and protein levels. Histidine 61-64 P53 Homo sapiens 42-45 11782367-7 2002 Transient expression of dominant-negative p53 ((175)Arg-->His) counteracted the detrimental effects of BPDE on BRCA-1 promoter activity and protein levels. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 106-110 P53 Homo sapiens 42-45 11782367-9 2002 We conclude that activation of the aromatic hydrocarbon receptor is not sufficient for down-regulation of BRCA-1 transcription, which is, however, inhibited by the B[a]P metabolite BPDE through a p53-dependent pathway. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 181-185 P53 Homo sapiens 196-199 11774260-0 2002 Apoptosis induced by low-dose paclitaxel is associated with p53 upregulation in nasopharyngeal carcinoma cells. Paclitaxel 30-40 P53 Homo sapiens 60-63 11774260-6 2002 We showed that paclitaxel inhibited growth and induced apoptosis in both cell lines but that the p53 mutant line (CNE-2) was less sensitive to treatment with low-dose paclitaxel. Paclitaxel 167-177 P53 Homo sapiens 97-100 11774260-8 2002 We observed a striking increase of p53 protein levels in NPC cells exposed to 1 and 10 nM paclitaxel but a marked inhibition at 100 nM paclitaxel treatment. Paclitaxel 90-100 P53 Homo sapiens 35-38 11774260-8 2002 We observed a striking increase of p53 protein levels in NPC cells exposed to 1 and 10 nM paclitaxel but a marked inhibition at 100 nM paclitaxel treatment. Paclitaxel 135-145 P53 Homo sapiens 35-38 11774260-10 2002 In summary, low-dose paclitaxel inhibited cell growth in NPC cells and induced apoptosis possibly by upregulation of p53. Paclitaxel 21-31 P53 Homo sapiens 117-120 11855756-9 2002 In Huh-7 cells (mutated p53), which were most sensitive to DOX, there was neither G1 nor G2 arrest, and the level of p53 mutated protein was downregulated after DOX treatment. Doxorubicin 59-62 P53 Homo sapiens 24-27 11855756-9 2002 In Huh-7 cells (mutated p53), which were most sensitive to DOX, there was neither G1 nor G2 arrest, and the level of p53 mutated protein was downregulated after DOX treatment. Doxorubicin 161-164 P53 Homo sapiens 24-27 11855756-9 2002 In Huh-7 cells (mutated p53), which were most sensitive to DOX, there was neither G1 nor G2 arrest, and the level of p53 mutated protein was downregulated after DOX treatment. Doxorubicin 161-164 P53 Homo sapiens 117-120 11855756-11 2002 p21 was upregulated following p53 activation at low doses of DOX in HepG2 cells, but at higher doses, p21 was downregulated in Huh-7 and HepG2 cells. Doxorubicin 61-64 P53 Homo sapiens 30-33 11855756-12 2002 CONCLUSION: DOX confers different chemosensitivity on different hepatoma cell lines with different p53 status. Doxorubicin 12-15 P53 Homo sapiens 99-102 11855756-13 2002 The contrasting relationships between chemosensitivity and p53 status and expression suggest that DOX-induced apoptosis and cell death involve pathways that are independent of p53. Doxorubicin 98-101 P53 Homo sapiens 59-62 11991084-0 2002 Cadmium-induced apoptosis of primary epithelial lung cells: involvement of Bax and p53, but not of oxidative stress. Cadmium 0-7 P53 Homo sapiens 83-86 11991084-4 2002 On exposure to 10 micromol/L CdAc, the levels of the apoptosis-modulating proteins p53 and Bax were increased at 2 h and 5-12 h, respectively. cadmium acetate 29-33 P53 Homo sapiens 83-86 11750847-14 2002 Treatment of Caki-1 cells with 5-FU enhanced the expression of p53 and bax, but had no effect on the expression of bcl-2. Fluorouracil 31-35 P53 Homo sapiens 63-66 11801552-10 2002 In skin biopsies from the same study, we demonstrate that topical DFMO significantly reduces the percentage of p53-positive cells (22%; P = 0.04); however, there were no significant changes in proliferating cell nuclear antigen or apoptotic indices, or in the frequency of p53 mutations (25% at baseline, 21% after placebo, and 26% after DFMO). Eflornithine 66-70 P53 Homo sapiens 111-114 11801552-10 2002 In skin biopsies from the same study, we demonstrate that topical DFMO significantly reduces the percentage of p53-positive cells (22%; P = 0.04); however, there were no significant changes in proliferating cell nuclear antigen or apoptotic indices, or in the frequency of p53 mutations (25% at baseline, 21% after placebo, and 26% after DFMO). Eflornithine 66-70 P53 Homo sapiens 273-276 11801552-11 2002 We conclude that inhibition of the premalignant AK lesions as well as a reduction in the expression of p53 and in spermidine concentrations may serve as surrogate endpoint biomarkers of DFMO and possibly other topically administered skin cancer chemopreventive agents. Eflornithine 186-190 P53 Homo sapiens 103-106 11801555-8 2002 The p53 oligonucleotide array detected 65 point mutations and four splice site mutations in different exons but missed all five frameshift mutations.

Arginine 4-12 P53 Homo sapiens 0-3 12056646-5 2002 A series of 129 oral squamous cell cancers was investgated retrospectively for expression of P53 protein by immunohistochemistry of paraffin-embedded tissue sections. Paraffin 132-140 P53 Homo sapiens 93-96 12599424-7 2002 Wild-type p53-positive HeLa was more sensitive to cisplatin, compared with the control cell lines. Cisplatin 50-59 P53 Homo sapiens 10-13 12658781-6 2002 When combined treatment of wild-type p53 gene transfection and cisplatin was used, that was significantly increased [IR (91.64 +/- 1.00)%, (94.98 +/- 1.67)%, (95.32 +/- 2.01)%, (95.65 +/- 1.00)%]. Cisplatin 63-72 P53 Homo sapiens 37-40 12440809-5 2002 In ovarian cancer p53 status is a strong predictor of response to platinum-based chemotherapy. Platinum 66-74 P53 Homo sapiens 18-21 12440809-6 2002 Patients whose tumors have p53 mutations experience a lower chance of achieving a complete response following platinum-based regimens when compared to patients without p53 mutations. Platinum 110-118 P53 Homo sapiens 27-30 12440809-7 2002 Conversely, experimental and clinical data seem to show that paclitaxel enhances apoptosis through a p53-independent pathway, that probably involves the Bax gene. Paclitaxel 61-71 P53 Homo sapiens 101-104 12440809-8 2002 Whereas patients with wild-type p53 tumors have a good chance to respond to platinum, patients with mutant p53 tumors may have a clinical benefit from the addition of paclitaxel to platinum-based chemotherapy. Platinum 76-84 P53 Homo sapiens 32-35 12440809-8 2002 Whereas patients with wild-type p53 tumors have a good chance to respond to platinum, patients with mutant p53 tumors may have a clinical benefit from the addition of paclitaxel to platinum-based chemotherapy.

Tamoxifen 100-109 P53 Homo sapiens 38-41 11995810-9 2002 They inhibited CEP-induced apoptosis in U251MG cells (a p53-mutant cell line), but not in U87MG cells (a p53 wild-type cell line), suggesting that in CEP-induced apoptosis two possible cascades are in play. cepharanthine 15-18 P53 Homo sapiens 56-59 11995810-9 2002 They inhibited CEP-induced apoptosis in U251MG cells (a p53-mutant cell line), but not in U87MG cells (a p53 wild-type cell line), suggesting that in CEP-induced apoptosis two possible cascades are in play. cepharanthine 150-153 P53 Homo sapiens 56-59 11862326-0 2002 Proliferation-dependent induction of apoptosis by the retinoid CD437 in p53-mutated keratinocytes. CD 437 63-68 P53 Homo sapiens 72-75 11862326-3 2002 We demonstrate that CD437 is also capable of inducing apoptosis in the non-tumorigenic keratinocyte cell line HaCaT that carries UV-type mutations on both alleles of the p53 gene. CD 437 20-25 P53 Homo sapiens 170-173 11862326-7 2002 The potent, selective, and p53-independent apoptosis-inducing efficacy of CD437 is of utmost importance for the prophylaxis and treatment of skin cancer caused by mutational inactivation of the p53 gene. CD 437 74-79 P53 Homo sapiens 27-30 11862326-7 2002 The potent, selective, and p53-independent apoptosis-inducing efficacy of CD437 is of utmost importance for the prophylaxis and treatment of skin cancer caused by mutational inactivation of the p53 gene. CD 437 74-79 P53 Homo sapiens 194-197 11752120-3 2002 We found that, relative to control transfectants, there was a slight tendency for the p53 inactivated cells to be less sensitive to 5-FU after 6 days of continuous treatment. Fluorouracil 132-136 P53 Homo sapiens 86-89 11780126-2 2002 Here we demonstrate that homeodomain-interacting protein kinase-2 (HIPK2), a member of a novel family of nuclear serine/threonine kinases, binds to and activates p53 by directly phosphorylating it at Ser 46. Serine 200-203 P53 Homo sapiens 162-165 11740489-3 2002 HIPK2 is activated by ultraviolet (UV) radiation and selectively phosphorylates p53 at Ser 46, thus facilitating the CBP-mediated acetylation of p53 at Lys 382, and promoting p53-dependent gene expression.

Lysine 152-155 P53 Homo sapiens 80-83 12095159-3 2002 Thus, this work explored the ability of Zn to protect human neurons in culture (NT2-N) from Cu-mediated death and tested the hypotheses that the tumor-suppressor protein p53 plays a role in Cu-induced neuronal death and is part of the mechanism of Zn protection. Copper 190-192 P53 Homo sapiens 170-173 11740489-3 2002 HIPK2 is activated by ultraviolet (UV) radiation and selectively phosphorylates p53 at Ser 46, thus facilitating the CBP-mediated acetylation of p53 at Lys 382, and promoting p53-dependent gene expression.

Serine 63-66 P53 Homo sapiens 56-59 11780126-1 2002 Phosphorylation of p53 at Ser 46 was shown to regulate p53 apoptotic activity. Serine 26-29 P53 Homo sapiens 19-22 11780126-1 2002 Phosphorylation of p53 at Ser 46 was shown to regulate p53 apoptotic activity. Serine 26-29 P53 Homo sapiens 55-58 12088100-2 2002 Following tamoxifen treatment expression of HER-2 and p53 decreased but Bcl2 remained unchanged. Tamoxifen 10-19 P53 Homo sapiens 54-57 12095159-3 2002 Thus, this work explored the ability of Zn to protect human neurons in culture (NT2-N) from Cu-mediated death and tested the hypotheses that the tumor-suppressor protein p53 plays a role in Cu-induced neuronal death and is part of the mechanism of Zn protection.

Arginine 41-44 P53 Homo sapiens 48-51 11741290-7 2001 The p53 induced by both drugs was able to bind to DNA; however, only the p53 induced by camptothecin was phosphorylated at serine-392. Serine 123-129 P53 Homo sapiens 4-7 11741290-7 2001 The p53 induced by both drugs was able to bind to DNA; however, only the p53 induced by camptothecin was phosphorylated at serine-392. Serine 123-129 P53 Homo sapiens 73-76 11716543-2 2001 We found that curcumin caused cell death in eight melanoma cell lines, four with wild-type and four with mutant p53. Curcumin 14-22 P53 Homo sapiens 112-115 11716543-10 2001 Since melanoma cells with mutant p53 are strongly resistant to conventional chemotherapy, curcumin may overcome the chemoresistance of these cells and provide potential new avenues for treatment. Curcumin 90-98 P53 Homo sapiens 33-36 11744405-13 2001 However, permanent H(2)O(2) levels induce the tumour suppressor p53 which in turn downregulates cytosolic TR. Hydrogen Peroxide 19-27 P53 Homo sapiens 64-67 12030785-6 2001 In addition, the status of ATM, p53, PTEN/Akt and 14-3-3 are also associated with rapamycin sensitivity. Sirolimus 82-91 P53 Homo sapiens 32-35 11753676-4 2001 However, RA sensitive CA-OV3 cells expressed higher levels of p53, p27, p21, and p16 compared to RA resistant SK-OV3 cells. Tretinoin 9-11 P53 Homo sapiens 62-65 11813984-10 2001 MAL-PEG conjugation coupled to western analysis detected a minimum of 0.23 pmol of oxidized p53. Polyethylene Glycols 4-7 P53 Homo sapiens 92-95 11728383-6 2001 We also observed that a paclitaxel-resistant cell line expressed Bax at a much lower level than the sensitive parental line [A2780(1A9)], consistent with its mutant p53 status. Paclitaxel 24-34 P53 Homo sapiens 165-168 11745454-3 2001 Using the human wild-type p53-expressing HCT116 colon carcinoma cell line and HCT116 cells with both p53 alleles inactivated by homologous recombination, we show in the current study that resveratrol at concentrations comparable to those found in some foods can induce apoptosis independently of p53. Resveratrol 188-199 P53 Homo sapiens 26-29 11745454-3 2001 Using the human wild-type p53-expressing HCT116 colon carcinoma cell line and HCT116 cells with both p53 alleles inactivated by homologous recombination, we show in the current study that resveratrol at concentrations comparable to those found in some foods can induce apoptosis independently of p53. Resveratrol 188-199 P53 Homo sapiens 101-104 11745454-3 2001 Using the human wild-type p53-expressing HCT116 colon carcinoma cell line and HCT116 cells with both p53 alleles inactivated by homologous recombination, we show in the current study that resveratrol at concentrations comparable to those found in some foods can induce apoptosis independently of p53. Resveratrol 188-199 P53 Homo sapiens 101-104 11745454-6 2001 When compared with 5-FU, resveratrol stimulated p53 accumulation and activity only weakly and with delayed kinetics and neither the increased levels nor the activity affected apoptosis detectably. Resveratrol 25-36 P53 Homo sapiens 48-51 11745454-9 2001 Thus, resveratrol triggers a p53-independent apoptotic pathway in HCT116 cells that may be linked to differentiation. Resveratrol 6-17 P53 Homo sapiens 29-32 11720736-7 2001 Although several different exogenous carcinogens have been shown to selectively target p53, evidence supporting the endogenous insult of p53 from oxyradical and nitrogen-oxyradicals is accumulating.

Alanine 319-327 P53 Homo sapiens 126-129 11713288-7 2001 Finally, the region between the DBD and the oligomerization domain of p53, specifically lysine 305, also plays a critical role in fully revealing p53NES. Lysine 88-94 P53 Homo sapiens 70-73 11753684-7 2001 To examine the role of p53 in these functions, we showed that suppression of p53 level with antisense oligonucleotide abrogated triptolide-induced apoptosis and over-expression of dominant negative p53 abolished the inhibitory effect on NF-kappaB activation. Oligonucleotides 102-117 P53 Homo sapiens 77-80 11753684-7 2001 To examine the role of p53 in these functions, we showed that suppression of p53 level with antisense oligonucleotide abrogated triptolide-induced apoptosis and over-expression of dominant negative p53 abolished the inhibitory effect on NF-kappaB activation. Oligonucleotides 102-117 P53 Homo sapiens 77-80 11551930-10 2001 In vitro kinase assays followed by immunoblotting showed that serine 20 of p53 was a target of Plk3. Serine 62-68 P53 Homo sapiens 75-78 11551930-11 2001 Furthermore, expression of a kinase-defective Plk3 mutant (Plk3(K52R)) resulted in significant reduction of p53 phosphorylation on serine 20, which was correlated with a decrease in the expression of p21 and with a concomitant increase in cell proliferation. Serine 131-137 P53 Homo sapiens 108-111 11719428-2 2001 In a kindred with LFS without an inherited TP53 mutation, we have previously reported a truncating mutation (1100delC) in CHK2, encoding a kinase that phosphorylates p53 on Ser(20). Serine 173-176 P53 Homo sapiens 166-169 11709716-8 2001 Moreover, upregulation of p53 through serine 20 phosphorylation, does not occur in G2. Serine 38-44 P53 Homo sapiens 26-29 11709055-7 2001 These observations suggest a model in which the NF-kappaB switch from an anti-apoptotic to a pro-apoptotic role within the cell results from modulation of its ability to stimulate gene expression, possibly as a result of the ability of p53 to sequester transcriptional co-activator proteins such as p300/CREB (cAMP-response-element-binding protein)-binding protein.

Cisplatin 44-53 P53 Homo sapiens 14-17 11761456-7 2001 These results provide evidence that ERK activity during the cisplatin DNA damage response, regulates in part, these cell cycle control (p21WAF1, Gadd45), DNA repair (Gadd45) and p53-regulatory (Mdm2) proteins. Cisplatin 60-69 P53 Homo sapiens 178-181 11761456-3 2001 Furthermore, we have demonstrated that cisplatin-induced ERK activation is required for optimal p53 protein accumulation following cisplatin-induced DNA damage. Cisplatin 39-48 P53 Homo sapiens 96-99 11761456-3 2001 Furthermore, we have demonstrated that cisplatin-induced ERK activation is required for optimal p53 protein accumulation following cisplatin-induced DNA damage. Cisplatin 131-140 P53 Homo sapiens 96-99 11761456-4 2001 In the present study, we expanded our investigations to examine the effect of cisplatin-induced ERK activation on the expression of p53-targeted genes that have been shown to be important in the cellular response to DNA damage including Bax, Bcl-2, Bcl-x1, Cyclin G, Gadd45, p21WAF1, and Mdm2. Cisplatin 78-87 P53 Homo sapiens 132-135 11710828-10 2001 The results indicate that women homozygotic for arg/arg in codon 72 of the p53 gene are at an increased risk for the development of cervical adenocarcinomas.

Fatty Acids, Volatile 0-23 P53 Homo sapiens 102-105 11673474-9 2001 Our results indicate that suppression of p53 expression in HMECs by HPV-16 E6 and ODNs may sensitize cells to rECM-induced apoptosis and suggest a role for the alpha3/beta1-heterodimer in mediating apoptosis in HMECs grown in contact with rECM. recm 110-114 P53 Homo sapiens 41-44 11673474-9 2001 Our results indicate that suppression of p53 expression in HMECs by HPV-16 E6 and ODNs may sensitize cells to rECM-induced apoptosis and suggest a role for the alpha3/beta1-heterodimer in mediating apoptosis in HMECs grown in contact with rECM. recm 239-243 P53 Homo sapiens 41-44 11672522-3 2001 Nicotinamide (Vitamin B3) inhibits an NAD-dependent p53 deacetylation induced by Sir2alpha, and also enhances the p53 acetylation levels in vivo. NAD 38-41 P53 Homo sapiens 52-55 11672523-0 2001 hSIR2(SIRT1) functions as an NAD-dependent p53 deacetylase.

Cadmium 26-28 P53 Homo sapiens 0-3 11594760-1 2001 Full-length human p53 protein was examined using tryptophan fluorescence and circular dichroism spectroscopy (CD) to monitor unfolding. Tryptophan 49-59 P53 Homo sapiens 18-21 11594760-9 2001 Examination of X-ray structures containing two of the four tryptophan residues of a p53 monomer suggested local environments consistent with quenched fluorophores. Tryptophan 59-69 P53 Homo sapiens 84-87 11489880-3 2001 Restoration of p53 triggered a G(2)/M cell cycle arrest and enhanced BAX protein expression, without inducing apoptosis or potentiating the cytotoxic effect of etoposide, vincristine, and cis-platinum. Cisplatin 188-200 P53 Homo sapiens 15-18 11495913-3 2001 Among the postulated phosphorylation sites involved in p53 stabilization or activation (Ser(15), Ser(20), Ser(33), and Ser(46)), only Ser(33) was phosphorylated. Serine 88-91 P53 Homo sapiens 55-58 11710828-10 2001 The results indicate that women homozygotic for arg/arg in codon 72 of the p53 gene are at an increased risk for the development of cervical adenocarcinomas. Arginine 52-55 P53 Homo sapiens 75-78 11495913-4 2001 Furthermore, interaction of p53 with the transcriptional coactivator p300 was induced, and Lys(382) of p53 was acetylated.

Lysine 91-94 P53 Homo sapiens 103-106 11518699-4 2001 Phosphorylation of p300 at serine 89 by AMP-kinase dramatically reduced its interaction, in vitro and in vivo, with the nuclear receptors peroxisome proliferator-activated receptor gamma, thyroid receptor, retinoic acid receptor, and retinoid X receptor, but did not affect its interaction with the non-nuclear receptor transcription factors E1a, p53, or GATA4. Serine 27-33 P53 Homo sapiens 347-350 11495913-7 2001 Activated p38(MAPK) phosphorylated endogenous p53 at Ser(33) in living cells. Serine 53-56 P53 Homo sapiens 46-49 11495913-9 2001 These results suggest that phosphorylation at Ser(33) by p38(MAPK) is critical for activation of p53 following osmotic shock. Serine 46-49 P53 Homo sapiens 97-100 11594730-4 2001 Experiments in vitro demonstrate that peroxynitrite treatment of recombinant wild-type p53 at physiological concentrations results in formation of higher molecular weight aggregates, tyrosine nitration, and loss of specific DNA binding. Tyrosine 183-191 P53 Homo sapiens 87-90 11687964-0 2001 Difference in the centrosome duplication regulatory activity among p53 "hot spot" mutants: potential role of Ser 315 phosphorylation-dependent centrosome binding of p53. Serine 109-112 P53 Homo sapiens 165-168 11687964-9 2001 Since cyclin-dependent kinase 2 (CDK2) triggers initiation of centrosome duplication, and p53 is phosphorylated on Ser 315 by CDK2, we examined the p53 mutants with a replacement of Ser 315 to Ala (A) and Asp (D), both of which retain the transactivation function. Serine 115-118 P53 Homo sapiens 90-93 11687964-12 2001 Thus, p53 controls the centrosome duplication cycle both in transactivation-dependent and transactivation-independent manners, and the ability to bind to unduplicated centrosomes, which is controlled by phosphorylation on Ser 315, may be important for the overall p53-mediated regulation of centrosome duplication. Serine 222-225 P53 Homo sapiens 6-9 11687964-12 2001 Thus, p53 controls the centrosome duplication cycle both in transactivation-dependent and transactivation-independent manners, and the ability to bind to unduplicated centrosomes, which is controlled by phosphorylation on Ser 315, may be important for the overall p53-mediated regulation of centrosome duplication. Serine 222-225 P53 Homo sapiens 264-267 11583595-3 2001 Previous studies have suggested that DNA-damage-induced phosphorylation of p53 at key N-terminal sites has a pivotal role in regulating the interaction with Mdm2 but the precise role of phosphorylation of serines 15 and 20 is still unclear. Serine 205-212 P53 Homo sapiens 75-78 11583595-5 2001 In contrast, replacement of serine 20 makes p53 highly sensitive to Mdm2-mediated turnover. Serine 28-34 P53 Homo sapiens 44-47 11602639-2 2001 In syncytial apoptosis, phosphorylation of p53 on serine 15 (p53S15) precedes Bax upregulation, the apoptosis-linked conformational change of Bax, the insertion of Bax in mitochondrial membranes, subsequent release of cytochrome c, caspase activation, and apoptosis. Serine 50-56 P53 Homo sapiens 43-46 11594730-5 2001 Peroxynitrite treatment of human glioma cell lysates similarly resulted in selective tyrosine nitration of p53 and was also associated with loss of p53 DNA binding ability.

Cisplatin 44-53 P53 Homo sapiens 0-3 11576999-0 2001 p53-independent apoptosis mediated by tachpyridine, an anti-cancer iron chelator. Iron 67-71 P53 Homo sapiens 0-3 11477076-5 2001 However, glutathione S-transferase-fused and thus dimerized p63 and p53 core domains had similar affinity and specificity for the p53 consensus sites p21, gadd45, cyclin G, and bax. Glutathione 9-20 P53 Homo sapiens 68-71 11477076-5 2001 However, glutathione S-transferase-fused and thus dimerized p63 and p53 core domains had similar affinity and specificity for the p53 consensus sites p21, gadd45, cyclin G, and bax. Glutathione 9-20 P53 Homo sapiens 130-133 11686576-3 2001 Previously, we demonstrated that the demise of human hepatoma Hep G2 cells mediated by folate deficiency proceeded via a p53-independent apoptosis, and the perturbation of intracellular calcium homeostasis was also shown to be involved. Folic Acid 87-93 P53 Homo sapiens 121-124 11709715-5 2001 We found that TCR-deficient (XP-A, XP-B and CS-B) fibroblasts were more sensitive than TCR-proficient cells (XP-C and normal) to both UV light and cisplatin treatment and this increase in sensitivity was not p53 dependent. Cisplatin 147-156 P53 Homo sapiens 208-211 11709715-8 2001 Therefore, we propose that p53 protects against UV- and cisplatin-induced apoptosis in a TCR-dependent manner and that p53 does not contribute strongly to the induction of apoptosis in TCR-deficient fibroblasts. Cisplatin 56-65 P53 Homo sapiens 27-30 11576999-13 2001 Since over 50% of human tumors contain a functionally defective p53 that reduces sensitivity to commonly used chemotherapeutic agents, such as etoposide and cisplatin, the ability of tachpyridine to induce apoptosis independently of p53 may offer an advantage in anti-tumor therapy. Cisplatin 157-166 P53 Homo sapiens 64-67 11585742-0 2001 Methylated CpG dinucleotides are the preferential targets for G-to-T transversion mutations induced by benzo[a]pyrene diol epoxide in mammalian cells: similarities with the p53 mutation spectrum in smoking-associated lung cancers. cytidylyl-3'-5'-guanosine 11-28 P53 Homo sapiens 173-176 11585742-0 2001 Methylated CpG dinucleotides are the preferential targets for G-to-T transversion mutations induced by benzo[a]pyrene diol epoxide in mammalian cells: similarities with the p53 mutation spectrum in smoking-associated lung cancers. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 103-130 P53 Homo sapiens 173-176 11585742-3 2001 p53 codons containing methylated CpG sequences are preferential targets for formation of adducts by (+/-) anti-7beta,8alpha-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE). 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 190-194 P53 Homo sapiens 0-3 11585729-3 2001 One of these modifications is dephosphorylation of Ser(376), which leads to association of p53 with 14-3-3 proteins.

Serine 57-64 P53 Homo sapiens 114-117 11526498-10 2001 In addition, activation of p53 by ATM requires multiple serine residues in p53"s transactivation domain. Serine 56-62 P53 Homo sapiens 27-30 11526498-10 2001 In addition, activation of p53 by ATM requires multiple serine residues in p53"s transactivation domain. Serine 56-62 P53 Homo sapiens 75-78 11493433-4 2001 These pathways are themselves influenced by a number of lipid products (diacylglycerol, sphingosine-1 phosphate, and glucosyl ceramide), reactive oxygen species, oncogenes (such as the tumor suppressor gene p53), protein kinases (protein kinase C and phosphoinositide-3 kinase), and external stimuli (hematopoietic growth factors and the extracellular matrix). Reactive Oxygen Species 137-160 P53 Homo sapiens 207-210 11481424-7 2001 Furthermore, p33ING2 expression increases the acetylation of p53 at Lys-382.

Prostaglandins 193-207 P53 Homo sapiens 164-167 11498783-7 2001 Although the basal mRNA levels of these genes did not depend on the presence of p53, we observed a p53-dependent induction of all these targets in response to gamma-irradiation and a p53-independent regulation for p21 and KILLER/DR5 in response to dexamethasone. Dexamethasone 248-261 P53 Homo sapiens 99-102 11390388-2 2001 Like the prostaglandins of the A series, prostaglandins of the J series have a structural determinant (endocyclic cyclopentenone) that confers the ability to impair the conformation, the phosphorylation, and the transcriptional activity of the p53 tumor suppressor with equivalent potency and efficacy. Prostaglandins 41-55 P53 Homo sapiens 244-247 11390388-4 2001 In seeking to understand how J series prostaglandins cause apoptosis despite their inactivation of p53, we discovered that they inhibit the ubiquitin isopeptidase activity of the proteasome pathway. Prostaglandins 38-52 P53 Homo sapiens 99-102 11521201-4 2001 We observed that an unmodified C-terminus was required for the suppression of apoptosis by the p53 135(Ala to Val) oncogenic p53 mutant. Alanine 103-106 P53 Homo sapiens 95-98 11521201-4 2001 We observed that an unmodified C-terminus was required for the suppression of apoptosis by the p53 135(Ala to Val) oncogenic p53 mutant. Alanine 103-106 P53 Homo sapiens 125-128 11498783-7 2001 Although the basal mRNA levels of these genes did not depend on the presence of p53, we observed a p53-dependent induction of all these targets in response to gamma-irradiation and a p53-independent regulation for p21 and KILLER/DR5 in response to dexamethasone. Dexamethasone 248-261 P53 Homo sapiens 99-102 11771346-6 2001 Moreover, there was also an interesting correlation between the degree of positivity to p53 and exposure to smoke, and to a lesser extent to alcohol, in the oncological patients. Alcohols 141-148 P53 Homo sapiens 88-91 11505395-2 2001 This combination also enhanced sensitivity to paclitaxel in a bcl-2 and mutant p53 expressing renal carcinoma cell line.

Serine 37-43 P53 Homo sapiens 15-18 11554448-3 2001 p53 is a zinc-binding protein containing several reactive cysteines, and its key biochemical property, sequence-specific DNA binding, is dependent upon metal and redox regulation in vitro. Cysteine 58-67 P53 Homo sapiens 0-3 11554448-3 2001 p53 is a zinc-binding protein containing several reactive cysteines, and its key biochemical property, sequence-specific DNA binding, is dependent upon metal and redox regulation in vitro. Metals 152-157 P53 Homo sapiens 0-3 11554448-4 2001 In this review, we describe the main features of p53 as a metalloprotein and we discuss how metal binding and oxidation-reduction may affect p53 activity in vivo. Metals 58-63 P53 Homo sapiens 49-52 11554448-8 2001 In this network, p53 can control the timely production of reactive oxygen intermediates (e.g., to initiate apoptosis), but this activity is itself under the control of changes in metal levels and in cellular redox status. Metals 179-184 P53 Homo sapiens 17-20 11483405-0 2001 Transcription factors p53 and HIF-1alpha as targets of nitric oxide.

Thioguanine 86-99 P53 Homo sapiens 186-189 11445851-3 2001 To characterize the involvement of the p53 gene abnormality in this disease, we analyzed expression and sequence alteration of p53 by immunohistochemical analysis of the protein expression and quantitative DNA/PCR and PCR-SSCP assays of the gene in 28 paraffin-embedded tissue specimens. Paraffin 252-260 P53 Homo sapiens 127-130 11483519-2 2001 A core domain mutant p53 (143 Val to Ala), in which two N-terminal residues (22 and 23) essential for transactivation were also mutated (Leu to Glu and Trp to Ser, respectively), was examined. Serine 159-162 P53 Homo sapiens 21-24 11445854-2 2001 Apoptotic inductions in MKN-45 and MKN-74 were stronger than those in MKN-28 and KATO-III, suggesting that wild-type p53 may contribute to the induction of apoptosis. MKN 24-27 P53 Homo sapiens 117-120 11445854-9 2001 In conclusion, our observations suggested that p53 mutation may be associated with apoptotic induction by 5-FU; however, p53 status may not strongly affect TS induction by 5-FU.

Paclitaxel 51-61 P53 Homo sapiens 34-37 11458051-5 2001 RESULTS: Significant paclitaxel dose dependent cytotoxicity was observed in J82 TCC cells lacking normal p53 and tsp53 transfected cells at 37C, which was the mutant p53 temperature in transfectants between maximal and minimal kill concentrations for either (p <0.001). Paclitaxel 21-31 P53 Homo sapiens 105-108 11458051-5 2001 RESULTS: Significant paclitaxel dose dependent cytotoxicity was observed in J82 TCC cells lacking normal p53 and tsp53 transfected cells at 37C, which was the mutant p53 temperature in transfectants between maximal and minimal kill concentrations for either (p <0.001). Paclitaxel 21-31 P53 Homo sapiens 115-118 11458051-8 2001 CONCLUSIONS: Paclitaxel requires functionally mutated p53 to induce cell death in human bladder cells, indicating that it may be more effective against TCC with p53 mutations than against TCC, which lacks p53 abnormalities, while gemcitabine is effective regardless of p53 function. Paclitaxel 13-23 P53 Homo sapiens 54-57 11458051-8 2001 CONCLUSIONS: Paclitaxel requires functionally mutated p53 to induce cell death in human bladder cells, indicating that it may be more effective against TCC with p53 mutations than against TCC, which lacks p53 abnormalities, while gemcitabine is effective regardless of p53 function. Paclitaxel 13-23 P53 Homo sapiens 161-164 11458051-8 2001 CONCLUSIONS: Paclitaxel requires functionally mutated p53 to induce cell death in human bladder cells, indicating that it may be more effective against TCC with p53 mutations than against TCC, which lacks p53 abnormalities, while gemcitabine is effective regardless of p53 function.

Doxorubicin 82-93 P53 Homo sapiens 41-44 11602059-8 2001 Flow cytometry showed that the accumulation of doxorubicin in wt-p53 transfectants was as 13 times as that of the pNeo transformants.

Tamoxifen 102-111 P53 Homo sapiens 51-54 11331294-4 2001 Here we show that the expression of PP5, an evolutionarily conserved Ser/Thr phosphatase that functions as an inhibitor of glucocorticoid- and p53-induced signaling cascades leading to growth suppression, is responsive to 17beta-estradiol (E(2)) in ER-positive human breast carcinoma cells (MCF-7). Estradiol 222-238 P53 Homo sapiens 143-146 11454885-3 2001 The aim of this study was to investigate interactions between adjuvant treatment with tamoxifen and the content of EGFR, HER2, and p53 in steroid receptor-positive patients.

Resveratrol 205-216 P53 Homo sapiens 38-41 11431734-6 2001 Ectopic expression of transcriptionally active p53 alone was not sufficient for the activation of apoptosis in p53-null Hep3B cells, but apoptosis was induced when endogenous Bcl-xL was simultaneously inhibited by antisense oligonucleotide in these cells. Oligonucleotides 224-239 P53 Homo sapiens 47-50 11395250-0 2001 High linear energy transfer carbon radiation effectively kills cultured glioma cells with either mutant or wild-type p53. Carbon 28-34 P53 Homo sapiens 117-120 11395250-8 2001 The effects of the carbon beams were not dependent on the p53 gene status but were reduced by G(1) arrest, which was independent of p21 expression. Carbon 19-25 P53 Homo sapiens 58-61 11471984-1 2001 The objective was to test the hypothesis that wild-type p53-function is required for the enhancement of the cytotoxicity of cis-diammine-dichloroplatinum(II) (cDDP) cytotoxicity by hyperthermia (HT).

Doxorubicin 67-77 P53 Homo sapiens 44-47 11439344-3 2001 At these low concentrations that are insufficient to inhibit mitotic progression, PTX induced both p53 and p21 causing G1 and G2 arrest in A549. Paclitaxel 82-85 P53 Homo sapiens 99-102 11439344-5 2001 Furthermore, we observed that the levels of p53 and p21 induced by adriamycin and by low concentrations of PTX in A549 cells were comparable. Paclitaxel 107-110 P53 Homo sapiens 44-47 11439344-6 2001 This observation led us to conclude that low concentrations of PTX can induce p53 and p21 sufficiently to cause G1 and G2.

We analysed the gene expression profile at different time points after p53 activation using oligonucleotide microarray capable of detecting approximately 11,000 mRNA species. Oligonucleotides 327-342 P53 Homo sapiens 150-153 11484952-6 2001 RESULTS: Expression of both p53 and Rb correlated with survival benefit after 5-FU treatment. Fluorouracil 78-82 P53 Homo sapiens 28-31 11384107-4 2001 IC(50)to cisplatin (CDDP) was 12.9 microM for SK-OV-3 cells and 9.2 microM for p53 gene-transducted SK-OV-3 cells. Cisplatin 9-18 P53 Homo sapiens 79-82 11384107-4 2001 IC(50)to cisplatin (CDDP) was 12.9 microM for SK-OV-3 cells and 9.2 microM for p53 gene-transducted SK-OV-3 cells. Cisplatin 20-24 P53 Homo sapiens 79-82 11384107-6 2001 Additionally, p53 gene transduction significantly enhanced CDDP-induced apoptosis. Cisplatin 59-63 P53 Homo sapiens 14-17 11384107-8 2001 In SK-OV-3 cells with transduction of the p53 gene, the expression of p53 and Bax proteins increased after exposure to CDDP. Cisplatin 119-123 P53 Homo sapiens 42-45 11384107-8 2001 In SK-OV-3 cells with transduction of the p53 gene, the expression of p53 and Bax proteins increased after exposure to CDDP. Cisplatin 119-123 P53 Homo sapiens 70-73 11401911-3 2001 A G to T transversion at codon 249 of the p53 gene (249(ser)) is commonly found in HCCs from patients in regions with dietary aflatoxin exposure. Serine 56-59 P53 Homo sapiens 42-45 11401911-4 2001 Because HBV infection is often endemic in high aflatoxin exposure areas, it is still unclear whether HBV acts as a confounder or as a synergistic partner in the development of the 249(ser) p53 mutation. Serine 184-187 P53 Homo sapiens 189-192 11697035-1 2001 The mechanism of metal-mediated DNA damage by carcinogenic danthron (1,8-dihydroxyanthraquinone) and anthraquinone was investigated by the DNA sequencing technique using 32P-labeled human DNA fragments obtained from the human c-Ha-ras-1 protooncogene and the p53 tumor suppressor gene. Metals 17-22 P53 Homo sapiens 259-262 26680792-9 2001 CONCLUSION: These findings suggest that Arg/Arg homozygocity of the p53 codon 72 would be a protective factor against the development of cervical adenocarcinoma. Arginine 40-43 P53 Homo sapiens 68-71 26680792-9 2001 CONCLUSION: These findings suggest that Arg/Arg homozygocity of the p53 codon 72 would be a protective factor against the development of cervical adenocarcinoma. Arginine 44-47 P53 Homo sapiens 68-71 11484935-2 2001 We found that four anticancer agents: etoposide, doxorubicin, bleomycin and paclitaxel induced apoptosis in human umbilical vein endothelial cells (HUVECs) (as judged by DNA fragmentation) with a time- and concentration-dependent decrease in bcl-2 protein but without the involvement of p53. Doxorubicin 49-60 P53 Homo sapiens 287-290 11484935-2 2001 We found that four anticancer agents: etoposide, doxorubicin, bleomycin and paclitaxel induced apoptosis in human umbilical vein endothelial cells (HUVECs) (as judged by DNA fragmentation) with a time- and concentration-dependent decrease in bcl-2 protein but without the involvement of p53. Paclitaxel 76-86 P53 Homo sapiens 287-290 11465510-3 2001 In order to determine if the genotype of the p53 donor or the genotype of the sp donor determined the binding efficiency, p53 expression was induced by retinoic acid and sp synthesis by bleomycin. Tretinoin 152-165 P53 Homo sapiens 122-125 11358908-10 2001 All tumour regions showed a point mutation in p53 gene at exon 7 (GGC (glycine)-->GTC (valine) at codon 245). Glycine 71-78 P53 Homo sapiens 46-49 11376010-2 2001 Here we report that a transient inhibition of spindle assembly induced by nocodazole, a tubulin-depolymerizing drug, triggers a stable activation of p53, which can transduce a cell cycle inhibitory signal even when the spindle-damaging agent is removed and the spindle is allowed to reassemble. Nocodazole 74-84 P53 Homo sapiens 149-152 11358908-11 2001 The distal portion of the duodenal tumour showed an additional point mutation in p53 gene at exon 5 (GCC (alanine)-->GTC (valine) at codon 129). Alanine 106-113 P53 Homo sapiens 81-84 11340581-12 2001 However, in other p53-deficient cells (osteosarcoma SAOS), taxane treatment was associated with hyperploid progression and the introduction of wild-type p53 resulted in a reduced sensivity. taxane 59-65 P53 Homo sapiens 18-21 11340581-13 2001 Although our approach does not allow definitive conclusions, these results suggest that loss of p53-dependent post-mitotic checkpoint results in a different time-course of taxane-induced cell death following DNA reduplication. taxane 172-178 P53 Homo sapiens 96-99 11340581-0 2001 A role for loss of p53 function in sensitivity of ovarian carcinoma cells to taxanes. Taxoids 77-84 P53 Homo sapiens 19-22 11340581-1 2001 Loss of p53 function has been linked to increased responsiveness to taxane treatment of ovarian carcinoma in clinical studies. taxane 68-74 P53 Homo sapiens 8-11 11340581-2 2001 We recently reported that the acquisition of cisplatin resistance in an ovarian carcinoma cell line (IGROV-1) was associated with mutation of p53 and collateral sensitivity to paclitaxel. Cisplatin 45-54 P53 Homo sapiens 142-145 11376010-3 2001 Cells transiently exposed to nocodazole continue to express high levels of p53 and p21 in the cell cycle that follows the transient exposure to nocodazole and become arrested in G(1), regardless of whether they carry a diploid or polyploid genome after mitotic exit. Nocodazole 29-39 P53 Homo sapiens 75-78 11376010-3 2001 Cells transiently exposed to nocodazole continue to express high levels of p53 and p21 in the cell cycle that follows the transient exposure to nocodazole and become arrested in G(1), regardless of whether they carry a diploid or polyploid genome after mitotic exit. Nocodazole 144-154 P53 Homo sapiens 75-78 11356930-5 2001 In nontransformed cells, WR-1065 protected cells from the cytotoxic effects of paclitaxel in a p53-dependent manner. Paclitaxel 79-89 P53 Homo sapiens 95-98 11484788-3 2001 In transformed TP53-mutated cell lines, however, the BBI-mediated radioprotection was absent. Amiodarone 53-56 P53 Homo sapiens 15-19 11484788-4 2001 At the molecular level, the radioprotective effect of BBI can be correlated with BBI-mediated stabilisation of TP53 protein prior to irradiation. Amiodarone 54-57 P53 Homo sapiens 111-115 11484788-4 2001 At the molecular level, the radioprotective effect of BBI can be correlated with BBI-mediated stabilisation of TP53 protein prior to irradiation. Amiodarone 81-84 P53 Homo sapiens 111-115 11484788-6 2001 Thus, the cell and molecular biological data presented suggest that BBI is able to protect cells with functional TP53 from UVB-induced DNA damage. Amiodarone 68-71 P53 Homo sapiens 113-117 11423970-3 2001 We found that treatment with roscovitine and olomoucin, which were originally developed as cyclin-dependent kinase (CDK) inhibitors, can efficiently stabilize and activate nuclear p53 in tumor cells with MDM2 amplification or cytoplasmic p53. butyrolactone I 45-54 P53 Homo sapiens 180-183 11482451-8 2001 In the TP53 mutant cell lines, DU145 and BM1604, dose enhancement factors (EFs) were found to be in the region of 4.20 for cisplatin, 3.70 for vinblastine, and 3.20 for etoposide. Cisplatin 123-132 P53 Homo sapiens 7-11 11482451-9 2001 In the TP53 wild-type cell line, LNCaP, the enhancement factors were low and in the region of 1.20 for cisplatin, vinblastine and etoposide. Cisplatin 103-112 P53 Homo sapiens 7-11 11423970-3 2001 We found that treatment with roscovitine and olomoucin, which were originally developed as cyclin-dependent kinase (CDK) inhibitors, can efficiently stabilize and activate nuclear p53 in tumor cells with MDM2 amplification or cytoplasmic p53. butyrolactone I 45-54 P53 Homo sapiens 238-241 11279110-5 2001 Second, we examined the relationship between p53 and HDM2 in the adriamycin-mediated stabilization of p53 in NB. Doxorubicin 65-75 P53 Homo sapiens 45-48 11311495-4 2001 5-fluorouracil (5FU) treatment resulted in a substantial increase in the p53-positive signet-ring cell population (from 17% to 45%) and in an increased Mdm2 immunoreactivity. Fluorouracil 0-14 P53 Homo sapiens 73-76 11311495-4 2001 5-fluorouracil (5FU) treatment resulted in a substantial increase in the p53-positive signet-ring cell population (from 17% to 45%) and in an increased Mdm2 immunoreactivity. Fluorouracil 16-19 P53 Homo sapiens 73-76 11279192-5 2001 Results of electrophoretic mobility shift assay showed specific interactions of p53 protein with p53-binding site oligonucleotides. Oligonucleotides 114-130 P53 Homo sapiens 80-83 11279110-5 2001 Second, we examined the relationship between p53 and HDM2 in the adriamycin-mediated stabilization of p53 in NB. Doxorubicin 65-75 P53 Homo sapiens 102-105 11279192-5 2001 Results of electrophoretic mobility shift assay showed specific interactions of p53 protein with p53-binding site oligonucleotides. Oligonucleotides 114-130 P53 Homo sapiens 97-100 11279192-6 2001 The DNA-protein complex formed in electrophoretic mobility shift assay was competed with unlabeled excess of p53-binding site oligonucleotide, unaffected with p53-binding site mutant or Sp1-binding site oligonucleotides, and supershifted with anti-p53 antibodies. Oligonucleotides 126-141 P53 Homo sapiens 109-112 11279110-7 2001 In support of this notion, p53 stabilization following adriamycin resulted in an inhibition of both p53 ubiquitination and HDM2 ligase activity. Doxorubicin 55-65 P53 Homo sapiens 27-30 11279192-9 2001 However, the treatment of cells with DNA alkylating agents methylmethane sulfonate and N-methyl-N"-nitro-N-nitrosoguanidine, which cause phosphorylation of p53 at Ser(15) and Ser(392), induced pAPCP promoter activity in HCT-116(p53(+/+)) cells. Serine 163-166 P53 Homo sapiens 156-159 11279110-7 2001 In support of this notion, p53 stabilization following adriamycin resulted in an inhibition of both p53 ubiquitination and HDM2 ligase activity. Doxorubicin 55-65 P53 Homo sapiens 100-103 11279192-9 2001 However, the treatment of cells with DNA alkylating agents methylmethane sulfonate and N-methyl-N"-nitro-N-nitrosoguanidine, which cause phosphorylation of p53 at Ser(15) and Ser(392), induced pAPCP promoter activity in HCT-116(p53(+/+)) cells. Serine 163-166 P53 Homo sapiens 228-231 11279192-9 2001 However, the treatment of cells with DNA alkylating agents methylmethane sulfonate and N-methyl-N"-nitro-N-nitrosoguanidine, which cause phosphorylation of p53 at Ser(15) and Ser(392), induced pAPCP promoter activity in HCT-116(p53(+/+)) cells. Serine 175-178 P53 Homo sapiens 156-159 11279186-7 2001 In addition, only major 1,2-GG intrastrand cross-links of cisplatin are responsible for this enhanced binding affinity of p53. Cisplatin 58-67 P53 Homo sapiens 122-125 11279192-9 2001 However, the treatment of cells with DNA alkylating agents methylmethane sulfonate and N-methyl-N"-nitro-N-nitrosoguanidine, which cause phosphorylation of p53 at Ser(15) and Ser(392), induced pAPCP promoter activity in HCT-116(p53(+/+)) cells. Serine 175-178 P53 Homo sapiens 228-231 11350044-3 2001 In this study we compared the cisplatin-induced response of p53 protein and its downstream targets p21WAF-1 and Mdm2 in the cisplatin-sensitive ovarian carcinoma cell line A2780 and its cisplatin-resistant derivative CP70. Cisplatin 30-39 P53 Homo sapiens 60-63 11350044-3 2001 In this study we compared the cisplatin-induced response of p53 protein and its downstream targets p21WAF-1 and Mdm2 in the cisplatin-sensitive ovarian carcinoma cell line A2780 and its cisplatin-resistant derivative CP70. Cisplatin 124-133 P53 Homo sapiens 60-63 11350044-3 2001 In this study we compared the cisplatin-induced response of p53 protein and its downstream targets p21WAF-1 and Mdm2 in the cisplatin-sensitive ovarian carcinoma cell line A2780 and its cisplatin-resistant derivative CP70. Cisplatin 124-133 P53 Homo sapiens 60-63 11350044-4 2001 A higher dose of cisplatin and a longer exposure time was required to achieve the same level of p53, p21WAF-1, and Mdm2 protein accumulation in the cisplatin-resistant CP70 cells versus cisplatin-sensitive A2780 cells. Cisplatin 17-26 P53 Homo sapiens 96-99 11350044-5 2001 A significant difference between the two cell lines was observed in cisplatin-induced stabilization of p53 protein. Cisplatin 68-77 P53 Homo sapiens 103-106 11350044-8 2001 These results demonstrate that in A2780 and CP70 cells resistance to cisplatin correlates with prolonged p53 protein stabilization and accumulation. Cisplatin 69-78 P53 Homo sapiens 105-108 11358811-3 2001 We identified mutations in exons 5-8 of p53 using DNA extracted from formalin-fixed paraffin-embedded tissue blocks from 146 whites and 26 non-whites with astrocytic glioma by PCR-single-strand conformation polymorphism and direct sequencing. Paraffin 84-92 P53 Homo sapiens 40-43 11279079-9 2001 Latent full-length p53 dissociated DNA aggregates via its core and CTD, and this effect was potentiated by GTP. Guanosine Triphosphate 107-110 P53 Homo sapiens 19-22 11279186-0 2001 Different recognition of DNA modified by aatitumor cisplatin and its clinically ineffective trans isomer by tumor suppressor protein p53. Cisplatin 51-60 P53 Homo sapiens 133-136 11279186-1 2001 The p53 gene encodes a nuclear phosphoprotein that is biologically activated in response to genotoxic stresses including treatment with anticancer platinum drugs. Platinum 147-155 P53 Homo sapiens 4-7 11279186-3 2001 DNA interactions of active wild-type human p53 protein with DNA fragments and oligodeoxyribonucleotide duplexes modified by antitumor cisplatin and its clinically ineffective trans isomer (transplatin) were investigated by using a gel mobility shift assay. Cisplatin 134-143 P53 Homo sapiens 43-46 11279186-4 2001 It was found that DNA adducts of cisplatin reduced binding affinity of the consensus DNA sequence to p53, whereas transplatin adducts did not. Cisplatin 33-42 P53 Homo sapiens 101-104 11279186-5 2001 This result was interpreted to mean that the precise steric fit required for the formation and stability of the tetrameric complex of p53 with the consensus sequence cannot be attained, as a consequence of severe conformational perturbations induced in DNA by cisplatin adducts. Cisplatin 260-269 P53 Homo sapiens 134-137 11279186-6 2001 The results also demonstrate an increase of the binding affinity of p53 to DNA lacking the consensus sequence and modified by cisplatin but not by transplatin. Cisplatin 126-135 P53 Homo sapiens 68-71 11279186-8 2001 The data base on structures of various DNA adducts of cisplatin and transplatin reveals distinctive structural features of 1,2-intrastrand cross-links of cisplatin, suggesting a unique role for this adduct in the binding of p53 to DNA lacking the consensus sequence. Cisplatin 54-63 P53 Homo sapiens 224-227 11279186-8 2001 The data base on structures of various DNA adducts of cisplatin and transplatin reveals distinctive structural features of 1,2-intrastrand cross-links of cisplatin, suggesting a unique role for this adduct in the binding of p53 to DNA lacking the consensus sequence. Cisplatin 154-163 P53 Homo sapiens 224-227 11279186-9 2001 The results support the hypothesis that the mechanism of antitumor activity of cisplatin may also be associated with its efficiency to affect the binding affinity of platinated DNA to active p53 protein. Cisplatin 79-88 P53 Homo sapiens 191-194 11497278-2 2001 We studied the mechanism of the growth-inhibitory effect of cisplatin (CDDP) on human pancreatic cancer cells in connection with the status of the p53 gene and expression of the bcl-2 family. Cisplatin 60-69 P53 Homo sapiens 147-150 11497278-2 2001 We studied the mechanism of the growth-inhibitory effect of cisplatin (CDDP) on human pancreatic cancer cells in connection with the status of the p53 gene and expression of the bcl-2 family. Cisplatin 71-75 P53 Homo sapiens 147-150 11497278-7 2001 Increased expression of bax and reduced expression of bcl-2 are involved in the growth-inhibitory effect of CDDP on pancreatic cancer cells with wild-type p53 gene. Cisplatin 108-112 P53 Homo sapiens 155-158 11350911-7 2001 The negative regulation of MGMT expression by wt p53 was confirmed in two other human isogenic cell lines, namely, the GM47.23 glioblastoma, which contains a dexamethasone-inducible wt p53, and the H460 lung cancer cell line, in which wt p53 had been inactivated by the human papillomavirus E6 protein. Dexamethasone 158-171 P53 Homo sapiens 49-52 11350904-12 2001 CONCLUSIONS: Our findings suggest that p53 alteration and MSI could be clinically useful molecular predictive markers for the identification of CRC patients who might benefit from 5-fluorouracil-based chemotherapy. Fluorouracil 180-194 P53 Homo sapiens 39-42 11477455-6 2001 The combination of Ad5CMV-p53 and cisplatin resulted in approximately 25% greater cytotoxicity compared to that observed with cisplatin alone in either cell line. Cisplatin 126-135 P53 Homo sapiens 26-29 11350911-7 2001 The negative regulation of MGMT expression by wt p53 was confirmed in two other human isogenic cell lines, namely, the GM47.23 glioblastoma, which contains a dexamethasone-inducible wt p53, and the H460 lung cancer cell line, in which wt p53 had been inactivated by the human papillomavirus E6 protein. Dexamethasone 158-171 P53 Homo sapiens 185-188 11350916-4 2001 Loss of cell viability, bcl-2 down-regulation, and poly(ADP-ribose) polymerase cleavage, indicative of apoptosis, also occurred in wt p53 C8161 cells on treatment with oligonucleotide 4625. Oligonucleotides 168-183 P53 Homo sapiens 134-137 11350911-7 2001 The negative regulation of MGMT expression by wt p53 was confirmed in two other human isogenic cell lines, namely, the GM47.23 glioblastoma, which contains a dexamethasone-inducible wt p53, and the H460 lung cancer cell line, in which wt p53 had been inactivated by the human papillomavirus E6 protein. Dexamethasone 158-171 P53 Homo sapiens 185-188 11350916-6 2001 In contrast to many other anticancer agents to which the apoptotic response is decreased because of p53 mutations, our data suggest that the bcl-2/bcl-xL bispecific antisense oligonucleotide 4625 effectively induces p53-independent apoptosis in human C8161 melanoma cells. Oligonucleotides 175-190 P53 Homo sapiens 216-219 11350916-0 2001 p53-Independent induction of apoptosis in human melanoma cells by a bcl-2/bcl-xL bispecific antisense oligonucleotide. Oligonucleotides 102-117 P53 Homo sapiens 0-3 11350916-3 2001 Upon treatment with oligonucleotide 4625, p53-mut C8161 cells showed earlier DNA damage, which occurred concomitantly with the reduction of bcl-2 and bcl-xL expression and the increase in the expression of proapoptotic bax. Oligonucleotides 20-35 P53 Homo sapiens 42-45 11295047-2 2001 A block of cell cycle checkpoint by dexamethasone and genistein correlates with a selective induction of cyclin-dependent kinase (Cdk) inhibitor p21WAF1/CIP1 in a tumor suppressor p53-independent manner and abolishment of Cdk2 phosphorylation.

Serine 41-47 P53 Homo sapiens 61-64 11313183-7 2001 In astrocytoma cells, cisplatin treatment resulted in the upregulation of p53, p21 and bax, while only p21 induction was observed after BBR3464 treatment. Cisplatin 22-31 P53 Homo sapiens 74-77 11313183-8 2001 In cisplatin-resistant cells, the reduced sensitivity to cisplatin paralleled a resistance to the induction of p53/p21 pathway by cisplatin, while the same doses of BBR3464 induced p21 to a similar extent in the resistant cells as in the parental cells. Cisplatin 3-12 P53 Homo sapiens 111-114 11313183-8 2001 In cisplatin-resistant cells, the reduced sensitivity to cisplatin paralleled a resistance to the induction of p53/p21 pathway by cisplatin, while the same doses of BBR3464 induced p21 to a similar extent in the resistant cells as in the parental cells. Cisplatin 57-66 P53 Homo sapiens 111-114 11313183-8 2001 In cisplatin-resistant cells, the reduced sensitivity to cisplatin paralleled a resistance to the induction of p53/p21 pathway by cisplatin, while the same doses of BBR3464 induced p21 to a similar extent in the resistant cells as in the parental cells. Cisplatin 57-66 P53 Homo sapiens 111-114 11316543-4 2001 METHODS AND MATERIALS: The nuclear expression of HAP1 and p53 proteins was studied by immunohistochemistry in paraffin-embedded material from 95 patients with locally advanced squamous cell head-and-neck cancer (HNC) treated with radical radiotherapy (38 cases with induction platinum-based chemotherapy and 57 with concurrent platinum chemoradiotherapy). Paraffin 110-118 P53 Homo sapiens 58-61 11783085-5 2001 Induction of p53 expression could be blocked by phosphorothiate analogs of antisense oligonucleotides to NF-kappa B p65 and LMP1, but not by NF-kappa B p50. Oligonucleotides 85-101 P53 Homo sapiens 13-16 11340094-0 2001 Tumor suppressor protein p53 mRNA and subcellular localization are altered by changes in cellular copper in human Hep G2 cells. Copper 98-104 P53 Homo sapiens 25-28 11340094-4 2001 Using Northern analysis, Western analysis, immunocytochemistry and the human hepatoma cell line Hep G2, this work showed that elevations in hepatocyte copper consistent with Wilson"s disease (5.7-fold increase) induced p53 mRNA and confirmed that copper toxicity is correlated with apoptotic cell death. Copper 151-157 P53 Homo sapiens 219-222 11340094-4 2001 Using Northern analysis, Western analysis, immunocytochemistry and the human hepatoma cell line Hep G2, this work showed that elevations in hepatocyte copper consistent with Wilson"s disease (5.7-fold increase) induced p53 mRNA and confirmed that copper toxicity is correlated with apoptotic cell death. Copper 247-253 P53 Homo sapiens 219-222 11340094-5 2001 However, Western analysis and immunocytochemistry showed that post-transcriptional mechanisms are a significant part of the process, with p53 translocation from the cytosol into the nucleus of copper-treated cells. Copper 193-199 P53 Homo sapiens 138-141 11340094-6 2001 Treatment of Hep G2 cells with increasing concentrations of the copper chelator tetraethylenepentamine (TEPA, 0-50 micromol/L, 48 h) reduced cellular copper and increased mean p53 mRNA abundance by over fourfold with nuclear translocation of the wild-type protein. Copper 64-70 P53 Homo sapiens 176-179 11295094-6 2001 Pre-treatment with cis-diamminedichloroplatinum (II) (CDDP) at 0.1 microg/ml significantly suppressed tumor cell viability in NY and HuO-3N1 (mutated), but not in the other three lines including HT-1080 carrying the wild-type p53 gene, implying the existence of different mechanisms for the tumor suppressive effect of p53 gene transfection and CDDP. Cisplatin 19-52 P53 Homo sapiens 226-229 11295094-6 2001 Pre-treatment with cis-diamminedichloroplatinum (II) (CDDP) at 0.1 microg/ml significantly suppressed tumor cell viability in NY and HuO-3N1 (mutated), but not in the other three lines including HT-1080 carrying the wild-type p53 gene, implying the existence of different mechanisms for the tumor suppressive effect of p53 gene transfection and CDDP. Cisplatin 19-52 P53 Homo sapiens 319-322 11295094-6 2001 Pre-treatment with cis-diamminedichloroplatinum (II) (CDDP) at 0.1 microg/ml significantly suppressed tumor cell viability in NY and HuO-3N1 (mutated), but not in the other three lines including HT-1080 carrying the wild-type p53 gene, implying the existence of different mechanisms for the tumor suppressive effect of p53 gene transfection and CDDP.

Eflornithine 39-71 P53 Homo sapiens 0-3 11284622-5 2001 Because p53 status influences the expression of microtubule-associated proteins and hence the sensitivity of a tumor to taxanes, it is possible that molecular markers could be used to customize chemotherapy to individual patients. Taxoids 120-127 P53 Homo sapiens 8-11 11239457-1 2001 Phosphorylation of the human p53 protein at Ser-392 has been shown to be responsive to UV but not gamma irradiation.

Expression of p21 and phosphorylation of Stat1 were significantly induced by DFMO at 24 h. Luciferase assay and gel shift assay showed specific binding of Stat1 to the p21 promoter, and promoter activity was activated at 24 h. In dominant negative p53 expressing cells, DFMO significantly induced p21 expression, arrested cells at G(1) phase, and suppressed cell growth effectively. Eflornithine 0-4 P53 Homo sapiens 376-379 11162600-5 2001 DFMO induced MKN45 cell G(1) phase arrest after 48 h, and the percentage of G(1) arrest cells continued to increase until 72 h. Expression of p21 and phosphorylation of Stat1 were significantly induced by DFMO at 24 h. Luciferase assay and gel shift assay showed specific binding of Stat1 to the p21 promoter, and promoter activity was activated at 24 h. In dominant negative p53 expressing cells, DFMO significantly induced p21 expression, arrested cells at G(1) phase, and suppressed cell growth effectively.

Eflornithine 205-209 P53 Homo sapiens 376-379 11162600-6 2001 These results suggest that DFMO induced MKN45 cell arrest at G(1) phase in a p53 independent manner, and Stat1 is, at least in part, involved in G(1) arrest. Eflornithine 27-31 P53 Homo sapiens 77-80 11162602-6 2001 However, cisplatin neither reduced cyclin B1 expression nor induced G2 phase arrest, while it induced a comparable amount of p53 protein. Cisplatin 9-18 P53 Homo sapiens 125-128 11313973-4 2001 By prolonged nocodazole treatment, U251MG human glioma cell, which has a p53 mutation, underwent transient arrest at mitosis, and subsequently exited from mitotic arrest (termed "mitotic slippage") followed by DNA replication without cytokinesis, resulting in hyperploid formation. Nocodazole 13-23 P53 Homo sapiens 73-76 11139340-5 2001 In contrast, betulinic acid, a novel chemotherapeutic compound, induced apoptosis and KILLER/DR5 mRNA in melanoma and glioblastoma cells through a p53-independent mechanism. betulinic acid 13-27 P53 Homo sapiens 147-150 11313973-6 2001 By employing LN382 glioma cell that has a temperature-sensitive p53 mutation, we found that the activation of p53 prevents hyperploid formation after the prolonged nocodazole treatment. Nocodazole 164-174 P53 Homo sapiens 64-67 11313973-6 2001 By employing LN382 glioma cell that has a temperature-sensitive p53 mutation, we found that the activation of p53 prevents hyperploid formation after the prolonged nocodazole treatment.

Oligonucleotides 34-50 P53 Homo sapiens 19-22 11146441-10 2001 Co-incubation with p53 anti-sense oligo-nucleotide suppressed As(2)O(3)-induced intracellular p53 over-expression and apoptosis. Oligonucleotides 34-50 P53 Homo sapiens 94-97 11149936-6 2001 These changes in p21(Waf1) expression correlated with both the induction of DNA damage (as measured by micronucleus formation) as well as increased Ser-15 phosphorylation of p53. Serine 148-151 P53 Homo sapiens 174-177 11212257-2 2001 It was suggested that HPV 16 E6 variants and the p53 codon 72 arginine polymorphism could be progression markers. Arginine 62-70 P53 Homo sapiens 49-52 11212257-3 2001 Indeed, it has been demonstrated that specific E6 variants and p53 arginine were both enriched in cancer. Arginine 67-75 P53 Homo sapiens 63-66 11212257-5 2001 Our aim was thus to investigate whether p53 arginine is important for cervical carcinogenesis by scaling up samples of the two European cohorts, the initial results of which were reported previously. Arginine 44-52 P53 Homo sapiens 40-43 11212257-7 2001 We found p53 arginine to be increased in cancer of both cohorts, consistent with our previous concept. Arginine 13-21 P53 Homo sapiens 9-12 11212257-8 2001 Although specific E6 genotypes increased gradually with the severity of the lesion, p53 arginine was enriched in cancer only. Arginine 88-96 P53 Homo sapiens 84-87 11212257-10 2001 It is concluded that p53 arginine is a risk factor for cervical cancer but probably acts independently of E6 variants. Arginine 25-33 P53 Homo sapiens 21-24 11212259-0 2001 Human papillomavirus type 16 E6 inactivation of p53 in normal human mammary epithelial cells promotes tamoxifen-mediated apoptosis.

Tamoxifen 70-79 P53 Homo sapiens 14-17 11212259-5 2001 In contrast, early passage p53(+) HMEC-LXSN vector controls treated with 1.0 microM tamoxifen underwent G1-G0-phase arrest but did not undergo apoptosis. Tamoxifen 84-93 P53 Homo sapiens 27-30 11212259-6 2001 p53(-) HMEC-E6 cells rapidly acquired resistance to tamoxifen-mediated apoptosis after 10 passages in culture (in the absence of tamoxifen). Tamoxifen 52-61 P53 Homo sapiens 0-3 11212259-8 2001 Tamoxifen-mediated apoptosis in p53(-) HMEC-E6 cells was not blocked by inhibitors of transcription and protein synthesis. Tamoxifen 0-9 P53 Homo sapiens 32-35 11212259-9 2001 These data suggest that the acute loss of p53 function in HMECs by expression of HPV-16 E6 results in marked sensitivity to tamoxifen-mediated apoptosis but that resistance to apoptosis rapidly develops within 10 passages in vitro. Tamoxifen 124-133 P53 Homo sapiens 42-45 11212244-8 2001 p53 expression was significantly elevated in the cells treated with CV787 and taxane. taxane 78-84 P53 Homo sapiens 0-3 11313944-0 2001 Taxol-induced apoptosis depends on MAP kinase pathways (ERK and p38) and is independent of p53. Paclitaxel 0-5 P53 Homo sapiens 91-94 11313944-4 2001 We found that Taxol treatment strongly activated ERK, p38 MAP kinase and p53 in MAP kinase MCF7 cells prior to apoptosis. Paclitaxel 14-19 P53 Homo sapiens 73-76 11313944-8 2001 However, cells with inactivated p53, unlike cells harboring wild type p53, failed to arrest in G2/M after treatment with Taxol and continued to divide or go into apoptosis. Paclitaxel 121-126 P53 Homo sapiens 32-35 11313944-9 2001 Our data show that both ERK and p38 MAP kinase cascades are essential for apoptotic response to Taxol-induced cellular killing and are independent of p53 activity. Paclitaxel 96-101 P53 Homo sapiens 150-153 11313944-10 2001 However, p53 may serve as a survival factor in breast carcinoma cells treated with Taxol by blocking cells in G2/M phase of the cell cycle.

Iron 44-46 P53 Homo sapiens 232-235 11197251-2 2001 This study investigated the effect of folate supplementation on genomic DNA methylation and DNA strand breaks in exons 5-8 of the p53 gene of the colonic mucosa, two provisional biomarkers of colon cancer. Folic Acid 38-44 P53 Homo sapiens 130-133 11174479-1 2001 OBJECTIVE: It has recently been suggested that white women who are homozygous for the allele of the gene for wild-type p53 protein (TP53) that encodes arginine at position 72 are more susceptible to human papillomavirus-associated cervical carcinoma than are women who are heterozygous for this polymorphism and women who are homozygous for the allele that encodes proline at that position.

Fluorouracil 98-102 P53 Homo sapiens 17-20 11129289-4 2000 Paclitaxel was chosen for combination therapy in the preclinical study reported here due to its extensive use as a first-line therapy in ovarian cancer, its synergy with SCH58500 in preclinical cancer models, and its activation of p53-independent apoptosis, which might result in a "lowered threshold" for tumor cell death. Paclitaxel 0-10 P53 Homo sapiens 231-234 11205289-0 2000 Restoration of wild-type p53 activity enhances the sensitivity of pleural metastasis to cisplatin through an apoptotic mechanism. Cisplatin 88-97 P53 Homo sapiens 25-28 11205289-9 2000 In conclusion our results suggested that DOTAP is an efficient vector for mediating gene transfer in pleural metastatic cells offering advantages compared to viral vectors, while tumor suppressor genes such as p53 may be good candidates in combination with conventional therapy with CDDP that could be further developed for their use in local cancer gene therapy. Cisplatin 283-287 P53 Homo sapiens 210-213 11050000-5 2000 Expression of wt p53 also leads to cell cycle arrest and protection from doxorubicin (Dox)- and melphalan (Mel)-induced apoptosis.

Fluorouracil 16-20 P53 Homo sapiens 75-78 11064345-1 2000 BACKGROUND: The current study was undertaken to investigate the influence of wild-type or mutant p53 status on the radiosensitizing effect of paclitaxel in colorectal tumor cell lines. Paclitaxel 142-152 P53 Homo sapiens 97-100 11053243-0 2000 Progesterone facilitates chromosome instability (aneuploidy) in p53 null normal mammary epithelial cells.

Fluorouracil 214-218 P53 Homo sapiens 107-110 11106256-15 2000 In conclusion, we have shown that tamoxifen-stimulated T47D p53 mutant tumors can be developed rapidly with high-dose therapy (1.5 mg daily). Tamoxifen 34-43 P53 Homo sapiens 60-63 11106256-16 2000 The results from this model provide new opportunities to investigate the rapid development of drug resistance to adjuvant tamoxifen in patients with mutant p53 breast tumors. Tamoxifen 122-131 P53 Homo sapiens 156-159 12214088-5 2000 H2O2-treatment resulted in dose-dependent increases in cell death due to genomic and mitochondrial DNA damage associated with increased levels of 8-OHdG and the p53 and CD95 pro-apoptosis genes, reduced levels of the Bcl-2 survival gene, activation of JNK and p38 stress kinases, and inhibition of PI3 kinase survival signaling. Hydrogen Peroxide 0-4 P53 Homo sapiens 161-164 10922372-0 2000 Vanadate induces p53 transactivation through hydrogen peroxide and causes apoptosis. Hydrogen Peroxide 45-62 P53 Homo sapiens 17-20 11095436-7 2000 Furthermore, wt-p53 expression renders two out of four carcinoma cell lines (FRO and NPA) more sensitive to doxorubicin and one (FRO) to 5-fluorouracil, independent of treatment schedule. Doxorubicin 108-119 P53 Homo sapiens 16-19 11095436-7 2000 Furthermore, wt-p53 expression renders two out of four carcinoma cell lines (FRO and NPA) more sensitive to doxorubicin and one (FRO) to 5-fluorouracil, independent of treatment schedule. Fluorouracil 137-151 P53 Homo sapiens 16-19 11032919-0 2000 Increased expression levels of p53 correlate with good response to cisplatin-based chemotherapy in non-small cell lung cancer. Cisplatin 67-76 P53 Homo sapiens 31-34 11032919-8 2000 It is suggested that high p53 expression levels in tumors correlate with both good response to cisplatin-based chemotherapy and good survival of patients with advanced NSCLC.

Serine 38-41 P53 Homo sapiens 16-19 10922372-9 2000 These results demonstrate that vanadate induces p53 activation mainly through H(2)O(2) generation, and this activation is required for vanadate-induced apoptosis.

Arginine 77-85 P53 Homo sapiens 124-127 11046142-8 2000 Those differences are also manifest in HeLa cells which express the human papillomavirus E6 protein, suggesting that p53 C-terminal lysine residues are also implicated in E6-AP-mediated ubiquitination. Lysine 132-138 P53 Homo sapiens 117-120 11046142-9 2000 These data suggest that p53 C-terminal lysine residues are the main sites of ubiquitin ligation, which target p53 for proteasome-mediated degradation.

Alanine 186-193 P53 Homo sapiens 68-71 11033015-4 2000 For each of these mAbs we localized the epitope recognized on human p53 by the Spot method of multiple peptide synthesis, defined critical residues on p53 involved in the interaction by alanine scanning replacement experiments and determined kinetic parameters using real-time interaction analysis. Alanine 186-193 P53 Homo sapiens 151-154 10884389-2 2000 In this study, we show that BRCA1 is initially up-regulated, followed by a reduction to below basal levels in response to treatment with the DNA-damaging agents adriamycin and mitomycin C, and that the reduction of BRCA1 expression is dependent on the presence of wild-type p53. Doxorubicin 161-171 P53 Homo sapiens 274-277 11042698-0 2000 A serine 37 mutation associated with two missense mutations at highly conserved regions of p53 affect pro-apoptotic genes expression in a T-lymphoblastoid drug resistant cell line.

Oligonucleotides 163-179 P53 Homo sapiens 123-126 11042688-2 2000 Although all cell lines contain the same p53 mutations at codons 175 (Arg-->His) and 248 (Arg-->Gln), the constitutive levels of p53 were progressively increased with the resistance of the cells to teniposide. Histidine 79-82 P53 Homo sapiens 135-138 11042688-2 2000 Although all cell lines contain the same p53 mutations at codons 175 (Arg-->His) and 248 (Arg-->Gln), the constitutive levels of p53 were progressively increased with the resistance of the cells to teniposide.

Fluorouracil 154-158 P53 Homo sapiens 56-59 11023973-4 2000 This mode of regulation may serve as a paradigm for redox-sensing by eukaryotic transcription factors as most-including NF-kappaB, AP-1, and p53-contain reactive thiols in their DNA binding regions, the modification of which alters binding in vitro.

Paraffin 118-126 P53 Homo sapiens 56-59 10938392-0 2000 CDDP induces p53-dependent apoptosis in tongue cancer cells. cddp 0-4 P53 Homo sapiens 13-16 10938392-3 2000 On the other hand, overexpression of p53 in HSC-4 was observed without CDDP treatment and no elevation of Bax could be detected. cddp 71-75 P53 Homo sapiens 37-40 10938392-6 2000 It is suggested that p53 status may have predictive potential with regard to response to CDDP therapy. cddp 89-93 P53 Homo sapiens 21-24 10974634-6 2000 (c) Treatment of tumour cells by either gamma radiation or by cisplatin resulted in the induction of p53 independent of the origin of the tumour. Cisplatin 62-71 P53 Homo sapiens 101-104 10974634-7 2000 (d) Susceptibility of two cell lines, one with and one without constitutive expression of p53 showed that the expressing cells were more sensitive to gamma radiation (the percentage inhibition at 250 cGy was 57% versus -15%, P<0.01), and also cisplatin (the percentage inhibition at 1 microgram/ml was 71.0+/-6.0 versus 2.6+/-7.0, P<0.001). Cisplatin 246-255 P53 Homo sapiens 90-93 10974634-13 2000 Alternatively, if TP53 is wild-type, then the increased levels of p53 expression would enable the cells to become more susceptible to DNA damaging treatments such as cisplatin or gamma radiation. Cisplatin 166-175 P53 Homo sapiens 18-22 10974634-13 2000 Alternatively, if TP53 is wild-type, then the increased levels of p53 expression would enable the cells to become more susceptible to DNA damaging treatments such as cisplatin or gamma radiation. Cisplatin 166-175 P53 Homo sapiens 66-69 10974635-1 2000 We conducted this study to determine whether the sensitivity of ovarian cancer cells to paclitaxel (PTX) relates to cells undergoing p53-dependent apoptosis. Paclitaxel 88-98 P53 Homo sapiens 133-136 10974635-1 2000 We conducted this study to determine whether the sensitivity of ovarian cancer cells to paclitaxel (PTX) relates to cells undergoing p53-dependent apoptosis. Paclitaxel 100-103 P53 Homo sapiens 133-136 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Cisplatin 146-155 P53 Homo sapiens 65-69 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Cisplatin 146-155 P53 Homo sapiens 86-90 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Cisplatin 157-161 P53 Homo sapiens 65-69 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Cisplatin 157-161 P53 Homo sapiens 86-90 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Paclitaxel 203-206 P53 Homo sapiens 65-69 10974635-3 2000 In SK-OV-3 and KP cells, which have a homozygous deletion of the TP53 gene, wild-type TP53 gene-transduction markedly enhanced the sensitivity to cisplatin (CDDP), but did not enhance the sensitivity to PTX. Paclitaxel 203-206 P53 Homo sapiens 86-90 10974635-5 2000 After exposure to CDDP, p53 and Bax protein expression increased and Bcl-xL expression decreased in the KF cells and TP53 gene-transducted SK-OV-3 cells. Cisplatin 18-22 P53 Homo sapiens 24-27 10974635-5 2000 After exposure to CDDP, p53 and Bax protein expression increased and Bcl-xL expression decreased in the KF cells and TP53 gene-transducted SK-OV-3 cells. Cisplatin 18-22 P53 Homo sapiens 117-121 10974635-7 2000 Therefore, the role of p53 in CDDP-induced apoptosis depends upon the cell type. Cisplatin 30-34 P53 Homo sapiens 23-26 10974636-1 2000 To clarify the effect of a combination treatment consisting of a recombinant adenovirus carrying a wild-type TP53 gene (AxCATP53) and cisplatin (CDDP), we examined p53-dependent apoptosis in ovarian cancer xenografts with and without the wild-type TP53 gene. Cisplatin 145-149 P53 Homo sapiens 164-167 11070791-4 2000 Restoration of p53 protein function in LN382 cells at 34 degrees C reduced the cytotoxicity of etoposide and paclitaxel, whereas that of cisplatin and ACNU was not affected. Paclitaxel 109-119 P53 Homo sapiens 15-18 11070791-8 2000 These results indicate that cell cycle arrest induced by wild-type p53 function may abrogate the cytotoxic effects of etoposide and paclitaxel, which are dependent on G2M-associated apoptosis. Paclitaxel 132-142 P53 Homo sapiens 67-70 11240705-1 2000 Recent analysis of the codon-72 polymorphism of the p53 gene, the allele encoding proline or arginine, suggested that the homozygous Arg/Arg genotype is a significant risk factor for cervical cancer associated with human papillomavirus (HPV). Arginine 93-101 P53 Homo sapiens 52-55 11240705-1 2000 Recent analysis of the codon-72 polymorphism of the p53 gene, the allele encoding proline or arginine, suggested that the homozygous Arg/Arg genotype is a significant risk factor for cervical cancer associated with human papillomavirus (HPV). Arginine 133-136 P53 Homo sapiens 52-55 11240705-1 2000 Recent analysis of the codon-72 polymorphism of the p53 gene, the allele encoding proline or arginine, suggested that the homozygous Arg/Arg genotype is a significant risk factor for cervical cancer associated with human papillomavirus (HPV). Arginine 137-140 P53 Homo sapiens 52-55 10948336-3 2000 To characterize the involvement of the p53 gene abnormality in this disease, we analyzed expression and sequence alteration of p53 by immunohistochemical analysis of the protein expression and quantitative DNA/PCR and PCR-SSCP assays of the gene in 33 paraffin-embedded tissue specimens. Paraffin 252-260 P53 Homo sapiens 127-130 11191113-7 2000 These findings suggest that the AhR mediated the inverse expression patterns of BRCA-1 and p53 upon exposure to B[a]P. The treatment with BPDE induced S-phase arrest and reduced BRCA-1 mRNA levels. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 138-142 P53 Homo sapiens 91-94 10948341-5 2000 Immunostaining for p53 protein with 4 different antibodies was performed on paraffin-embedded specimens from 69 patients with adenocarcinoma and squamous cell carcinoma of the oesophagus. Paraffin 76-84 P53 Homo sapiens 19-22 11798837-2 2000 METHODS: Human lung adenocarcinoma cell line GLC-82 was transfected with adenovirus-mediated p53 gene (Ad-p53) combining with administration of either kind of chemotherapeutic agents-cisplatin (CDDP) and arsenic trioxide (As(2)O(3)). Cisplatin 183-192 P53 Homo sapiens 106-109 11126384-4 2000 Aflatoxin B1 exposure leads to mutations in the p53 tumor suppressor gene, most commonly a transversion in codon 249 that leads to a substitution of serine for arginine in the p53 protein. Serine 149-155 P53 Homo sapiens 48-51 11126384-4 2000 Aflatoxin B1 exposure leads to mutations in the p53 tumor suppressor gene, most commonly a transversion in codon 249 that leads to a substitution of serine for arginine in the p53 protein. Serine 149-155 P53 Homo sapiens 176-179 11126384-4 2000 Aflatoxin B1 exposure leads to mutations in the p53 tumor suppressor gene, most commonly a transversion in codon 249 that leads to a substitution of serine for arginine in the p53 protein. Arginine 160-168 P53 Homo sapiens 48-51 11126384-4 2000 Aflatoxin B1 exposure leads to mutations in the p53 tumor suppressor gene, most commonly a transversion in codon 249 that leads to a substitution of serine for arginine in the p53 protein. Arginine 160-168 P53 Homo sapiens 176-179 10944184-2 2000 A series of hydrophilic mutations at Met-340 and Leu-344 of human p53 were designed to disrupt the hydrophobic dimer-dimer interface of the tetrameric oligomerization domain of p53 (residues 325-355). Methionine 37-40 P53 Homo sapiens 177-180 11798837-2 2000 METHODS: Human lung adenocarcinoma cell line GLC-82 was transfected with adenovirus-mediated p53 gene (Ad-p53) combining with administration of either kind of chemotherapeutic agents-cisplatin (CDDP) and arsenic trioxide (As(2)O(3)). Cisplatin 183-192 P53 Homo sapiens 93-96 11798837-2 2000 METHODS: Human lung adenocarcinoma cell line GLC-82 was transfected with adenovirus-mediated p53 gene (Ad-p53) combining with administration of either kind of chemotherapeutic agents-cisplatin (CDDP) and arsenic trioxide (As(2)O(3)). Cisplatin 194-198 P53 Homo sapiens 93-96 10944184-2 2000 A series of hydrophilic mutations at Met-340 and Leu-344 of human p53 were designed to disrupt the hydrophobic dimer-dimer interface of the tetrameric oligomerization domain of p53 (residues 325-355). Methionine 37-40 P53 Homo sapiens 66-69 11798837-9 2000 CONCLUSION: After introduced into GLC-82 cells, Ad-p53 shows enhanced therapeutic efficiency for GLC-82 cells when combined with CDDP or As(2)O(3). Cisplatin 129-133 P53 Homo sapiens 51-54 10993958-5 2000 Additional cell loss occurred in 40-16 and HCT116 p53-/- cells following administration of Taxol before IR and 5-FU. Paclitaxel 91-96 P53 Homo sapiens 50-53 10962580-3 2000 We identified genomic DNA fragments to which mut p53 (Gly245-->Ser) could be cross-linked in vivo. Serine 66-69 P53 Homo sapiens 49-52 10962580-4 2000 Purified recombinant mut p53 (Gly245-->Ser) was able to bind specifically to such elements in PCR-EMSA in vitro, supporting the idea that this mut p53 protein interacts with genomic DNA in vivo. Serine 42-45 P53 Homo sapiens 25-28 10962580-4 2000 Purified recombinant mut p53 (Gly245-->Ser) was able to bind specifically to such elements in PCR-EMSA in vitro, supporting the idea that this mut p53 protein interacts with genomic DNA in vivo. Serine 42-45 P53 Homo sapiens 150-153 10962580-6 2000 Therefore we propose that structural determinants within these DNA elements are important for their interaction with mut p53 (Gly245-->Ser) in vivo. Serine 138-141 P53 Homo sapiens 121-124 10962580-0 2000 Identification of genomic DNA sequences bound by mutant p53 protein (Gly245-->Ser) in vivo. Serine 81-84 P53 Homo sapiens 56-59 10962580-2 2000 Therefore we analysed the binding of mutant (mut) p53 (Gly245-->Ser) in Onda 11 glioma cells to cellular DNA in vivo, using p53-specific chromatin immunoprecipitation (CHIP) after in vivo cross-linking of mut p53 to genomic DNA with cisplatin. Serine 67-70 P53 Homo sapiens 50-53 20955676-2 2000 METHODS: Expression of p53 protein , ER and PR in 147 NSCLC specimen was detected by SP immunohistochemistry method. TFF2 protein, human 85-87 P53 Homo sapiens 23-26 10993958-6 2000 Radiation sensitivity was unaffected by combined treatments, except for Taxol, irradiation, and 5-FU sequence in the HCT116 p53-/- and 40-16 cell lines, where radiation sensitivity determined by clonogenic survival curve slopes was doubled or quadrupled, respectively. Fluorouracil 96-100 P53 Homo sapiens 124-127 10951339-9 2000 The 1-year survival rates for patients with and without p53 mutation after treatment with weekly paclitaxel were 63% (95% confidence interval [CI], 31-100%) and 53% (95% CI, 33-86%), respectively. Paclitaxel 97-107 P53 Homo sapiens 56-59 10962554-9 2000 The p53-dependent expression of GIPs was confirmed by dependence of expression upon induction of wt p53 expression in the EB-1 cellular model and by up-regulation following activation of an endogenous wt p53 by treatment with adriamycin. Doxorubicin 226-236 P53 Homo sapiens 4-7 10933801-0 2000 Phosphorylation of human p53 on Thr-55. Threonine 32-35 P53 Homo sapiens 25-28 10933801-4 2000 Phosphoamino acid analysis and manual Edman degradation of the isolated phosphopeptides enabled us to unequivocally identify Thr-55 as the major phosphorylation site on p53. Threonine 125-128 P53 Homo sapiens 169-172 10933801-7 2000 These data define Thr-55 as a novel phosphorylation site and for the first time show threonine phosphorylation of human p53. Threonine 18-21 P53 Homo sapiens 120-123 10933801-7 2000 These data define Thr-55 as a novel phosphorylation site and for the first time show threonine phosphorylation of human p53. Threonine 85-94 P53 Homo sapiens 120-123 10951339-11 2000 These results provide clinical support for in vitro observations that paclitaxel can bypass mutant p53 and lead to tumor cell death by alternate pathway(s). Paclitaxel 70-80 P53 Homo sapiens 99-102 10951339-12 2000 Paclitaxel should be considered as a component of treatment for patients with metastatic NSCLC with tumors that have p53 mutations. Paclitaxel 0-10 P53 Homo sapiens 117-120 10918193-12 2000 Homozygous codon-72 p53-Arg apparently confers a higher susceptibility to HPV-associated cervical tumorigenesis. Arginine 24-27 P53 Homo sapiens 20-23 10969820-3 2000 Reactive oxygen species are known to be powerful inducers of p53 activity; moreover, they play a role in the execution of p53-dependent apoptosis. Reactive Oxygen Species 0-23 P53 Homo sapiens 61-64 10969820-3 2000 Reactive oxygen species are known to be powerful inducers of p53 activity; moreover, they play a role in the execution of p53-dependent apoptosis. Reactive Oxygen Species 0-23 P53 Homo sapiens 122-125 10951577-4 2000 The present study tested the hypothesis that reactive oxygen species (ROS) released from mitochondria regulate the cytosolic redox state and are required for the stabilization of p53 protein levels in response to hypoxia. Reactive Oxygen Species 45-68 P53 Homo sapiens 179-182 10951577-4 2000 The present study tested the hypothesis that reactive oxygen species (ROS) released from mitochondria regulate the cytosolic redox state and are required for the stabilization of p53 protein levels in response to hypoxia. Reactive Oxygen Species 70-73 P53 Homo sapiens 179-182 10951577-5 2000 Our results indicate that hypoxia (1.5% O2) increases mitochondrial ROS generation and increases p53 protein levels in human breast carcinoma MCF-7 cells and in normal human diploid fibroblast IMR-90 cells. Oxygen 40-42 P53 Homo sapiens 97-100 10951577-7 2000 The antioxidant N-acetylcysteine and the Cu/Zn superoxide dismutase inhibitor diethyldithiocarbamic acid abolished the hypoxia-induced increases in ROS and p53 levels. Acetylcysteine 16-32 P53 Homo sapiens 156-159 10951577-8 2000 Rotenone, an inhibitor of mitochondrial complex I, and 4,4"-diisothiocyanato-stilbene-2,2"-disulfonate, a mitochondrial anion channel inhibitor, also abolished the increase in ROS signal and p53 levels during hypoxia. 4,4"-diisothiocyanato-stilbene-2,2"-disulfonate 55-102 P53 Homo sapiens 191-194 10951577-8 2000 Rotenone, an inhibitor of mitochondrial complex I, and 4,4"-diisothiocyanato-stilbene-2,2"-disulfonate, a mitochondrial anion channel inhibitor, also abolished the increase in ROS signal and p53 levels during hypoxia. Reactive Oxygen Species 176-179 P53 Homo sapiens 191-194 10951577-12 2000 These results indicate that mitochondria regulate p53 protein levels during hypoxia through a redox-dependent mechanism involving ROS. Reactive Oxygen Species 130-133 P53 Homo sapiens 50-53 10945628-4 2000 Because poly(ADP-ribose) polymerase (PARP)-mediated NAD+/ATP depletion has been implicated in the nucleoside-induced killing of normal resting lymphocytes, we postulated that this mechanism might account for the p53-independent component of nucleoside cytotoxicity in CLL. NAD 52-56 P53 Homo sapiens 212-215 11038045-1 2000 BACKGROUND: We assessed the hypothesis that a compromised p53 function could account for the non response of colon cancer patients with low thymidylate synthase (TS) expression receiving a bolus 5-fluorouracil (5-FU) leucovorin (LV) combination. Fluorouracil 195-209 P53 Homo sapiens 58-61 11038045-1 2000 BACKGROUND: We assessed the hypothesis that a compromised p53 function could account for the non response of colon cancer patients with low thymidylate synthase (TS) expression receiving a bolus 5-fluorouracil (5-FU) leucovorin (LV) combination. Fluorouracil 211-215 P53 Homo sapiens 58-61 10945628-4 2000 Because poly(ADP-ribose) polymerase (PARP)-mediated NAD+/ATP depletion has been implicated in the nucleoside-induced killing of normal resting lymphocytes, we postulated that this mechanism might account for the p53-independent component of nucleoside cytotoxicity in CLL. Adenosine Triphosphate 57-60 P53 Homo sapiens 212-215 10945617-9 2000 Analysis of the p53 cDNA from several focus-derived strains lacking p53 activity revealed that each contained the same mutation, an A to G transition at codon 215, resulting in a change from serine to glycine. Serine 191-197 P53 Homo sapiens 16-19 10945617-9 2000 Analysis of the p53 cDNA from several focus-derived strains lacking p53 activity revealed that each contained the same mutation, an A to G transition at codon 215, resulting in a change from serine to glycine. Serine 191-197 P53 Homo sapiens 68-71 10945617-9 2000 Analysis of the p53 cDNA from several focus-derived strains lacking p53 activity revealed that each contained the same mutation, an A to G transition at codon 215, resulting in a change from serine to glycine. Glycine 201-208 P53 Homo sapiens 16-19 10945617-9 2000 Analysis of the p53 cDNA from several focus-derived strains lacking p53 activity revealed that each contained the same mutation, an A to G transition at codon 215, resulting in a change from serine to glycine. Glycine 201-208 P53 Homo sapiens 68-71 10897038-7 2000 In A2780 cells, glutathione exposure was followed by p21 and Bax induction and p53 up-regulation, as expected for genotoxic stress. Glutathione 16-27 P53 Homo sapiens 79-82 10955812-0 2000 Evidence for a dose-response effect between p53 (but not p21WAF1/Cip1) protein concentrations, survival, and responsiveness in patients with epithelial ovarian cancer treated with platinum-based chemotherapy. Platinum 180-188 P53 Homo sapiens 44-47 10897038-9 2000 Taken together, these results indicate that the cytotoxic effect of extracellular glutathione, related to membrane metabolism, is mediated by production of H(2)O(2) leading to DNA damage and a cellular response involving p53. Glutathione 82-93 P53 Homo sapiens 221-224 10891529-0 2000 Theophylline and cisplatin synergize in down regulation of BCL-2 induction of apoptosis in human granulosa cells transformed by a mutated p53 (p53 val135) and Ha-ras oncogene.

Cisplatin 17-26 P53 Homo sapiens 143-146 10893182-3 2000 As hydrogen peroxide and other oxidants can affect signal transduction pathways at several levels, the present study was aimed to verify: (i) the occurrence of GGT-dependent production of hydrogen peroxide in melanoma cells; (ii) the effects of GGT-dependent prooxidant reactions on known redox-sensitive cellular targets, i.e. protein thiols, the nuclear transcription factor NF-kappa B and p53. Hydrogen Peroxide 188-205 P53 Homo sapiens 392-395 10908664-0 2000 Inactivation of wild-type p53 tumor suppressor by electrophilic prostaglandins. Prostaglandins 64-78 P53 Homo sapiens 26-29 10942242-7 2000 Treatment with Me-Lex and 3-aminobenzamide results in augmented expression of p53 protein and of the X-ray repair cross-complementing 1 transcript (a component of base excision repair). 3-aminobenzamide 26-42 P53 Homo sapiens 78-81 11055588-9 2000 p53 antisense oligonucleotides not only reduced the level of p53 proteins but correspondingly also blocked the expression of p21(waf1/cip1) in FTS-treated colon cancer cells. Oligonucleotides 14-30 P53 Homo sapiens 0-3 11055588-9 2000 p53 antisense oligonucleotides not only reduced the level of p53 proteins but correspondingly also blocked the expression of p21(waf1/cip1) in FTS-treated colon cancer cells. Oligonucleotides 14-30 P53 Homo sapiens 61-64 10899928-5 2000 Untreated cells from both lines expressed negligible p53 levels; on the other hand, whereas p53 and p21(Cip1/Waf1) were rapidly up-regulated in doxorubicin-treated SH-SY5Y cells, such a response was not observed in CHP-100 cells. Doxorubicin 144-155 P53 Homo sapiens 53-56 10899928-5 2000 Untreated cells from both lines expressed negligible p53 levels; on the other hand, whereas p53 and p21(Cip1/Waf1) were rapidly up-regulated in doxorubicin-treated SH-SY5Y cells, such a response was not observed in CHP-100 cells. Doxorubicin 144-155 P53 Homo sapiens 92-95 10891493-6 2000 PCAF binds to the E1B 55-kDa protein and to a region near the C terminus of p53 encompassing Lys-320, the specific PCAF acetylation site.

Eicosanoids 18-29 P53 Homo sapiens 67-70 10908664-1 2000 The electrophilic eicosanoids prostaglandins A(1) or A(2) impaired p53-dependent transcription of endogenous genes and exogenous p53-luciferase reporter plasmids in RKO and HCT 116 colon cancer cells. Eicosanoids 18-29 P53 Homo sapiens 129-132 10908664-1 2000 The electrophilic eicosanoids prostaglandins A(1) or A(2) impaired p53-dependent transcription of endogenous genes and exogenous p53-luciferase reporter plasmids in RKO and HCT 116 colon cancer cells. Prostaglandins A 30-46 P53 Homo sapiens 67-70 10908664-1 2000 The electrophilic eicosanoids prostaglandins A(1) or A(2) impaired p53-dependent transcription of endogenous genes and exogenous p53-luciferase reporter plasmids in RKO and HCT 116 colon cancer cells.

Prostaglandins A 140-156 P53 Homo sapiens 77-80 10908664-3 2000 Prostaglandins A(1) and A(2) induced a conformational change in wild-type p53 that corresponded with its inactivation and its aberrant redistribution from the cytosol to the nucleus. Prostaglandins A 0-16 P53 Homo sapiens 74-77 10908664-5 2000 We conclude that electrophilic eicosanoids impair the role of wild-type p53 as a guardian of genomic integrity by a process distinct from somatic mutation or viral oncoprotein binding. Eicosanoids 31-42 P53 Homo sapiens 72-75 10951572-0 2000 The human vaccinia-related kinase 1 (VRK1) phosphorylates threonine-18 within the mdm-2 binding site of the p53 tumour suppressor protein.

Tamoxifen 273-282 P53 Homo sapiens 0-3 10914720-13 2000 The role of mutated p53 in preventing response is more evident in patients submitted to epirubicin, and this may be caused by the up-regulation of multidrug resistance gene expression by p53 inactivation.

Glutamic Acid 41-50 P53 Homo sapiens 30-33 10817929-2 2000 Among the intracellular events triggered by glutamate, we identified two transcriptional factors: the p50 member of the NF-kappaB family and the tumor suppressor phosphoprotein p53. Glutamic Acid 44-53 P53 Homo sapiens 177-180 10817929-3 2000 Pretreatment of the cultures with aspirin, which inhibits NF-kappaB activation, or with specific p53 antisense oligonucleotide, which inhibits p53 transcription, resulted in a complete prevention of glutamate-induced p53 induction and apoptosis.

Glutamic Acid 199-208 P53 Homo sapiens 97-100 10825467-1 2000 The dietary isothiocyanates and cancer chemopreventive agents phenethyl isothiocyanate and allyl isothiocyanate and their cysteine conjugates inhibited the growth and induced apoptosis of human leukaemia HL60 (p53-) and human myeloblastic leukaemia-1 cells (p53+) in vitro. Cysteine 122-130 P53 Homo sapiens 210-213 10825467-1 2000 The dietary isothiocyanates and cancer chemopreventive agents phenethyl isothiocyanate and allyl isothiocyanate and their cysteine conjugates inhibited the growth and induced apoptosis of human leukaemia HL60 (p53-) and human myeloblastic leukaemia-1 cells (p53+) in vitro. Cysteine 122-130 P53 Homo sapiens 258-261 10825467-10 2000 This suggests that caspase-8 has a critical role, and caspase-3 a supporting role, in isothiocyanate-induced apoptosis in which p53 is not an obligatory participant. isothiocyanic acid 86-100 P53 Homo sapiens 128-131 10910364-6 2000 p53 is acetylated at lysine 382 upon Ras expression, an event that is essential for its biological function. Lysine 21-27 P53 Homo sapiens 0-3 10893263-5 2000 A mutant defective in GTP binding does not trigger apoptosis, indicating that increased levels of dyn2.GTP, rather than protein levels per se, are required to transduce signals that activate p53.

Glutamic Acid 199-208 P53 Homo sapiens 143-146 10817929-5 2000 Then, we studied the expression of two p53 downstream genes that could participate in the glutamate-induced pro-apoptotic pathway: p21, which codes for an inhibitor of different cyclin dependent kinases, and MSH2, which codes for a protein involved in the recognition and repair of DNA mismatches. Glutamic Acid 90-99 P53 Homo sapiens 39-42 10817929-7 2000 However, very soon after a brief exposure of the cells to glutamate, the expression of both proteins was dramatically enhanced.On these bases, we propose NF-kappaB, p53, p21 and MSH2 as relevant contributors of the glutamate-induced pro-apoptotic pathway. Glutamic Acid 58-67 P53 Homo sapiens 165-168 10817929-7 2000 However, very soon after a brief exposure of the cells to glutamate, the expression of both proteins was dramatically enhanced.On these bases, we propose NF-kappaB, p53, p21 and MSH2 as relevant contributors of the glutamate-induced pro-apoptotic pathway.

Tretinoin 35-37 P53 Homo sapiens 152-155 10749849-9 2000 The physiological relevance of GKLF in mediating p53-dependent induction of p21(WAF1/Cip1) is demonstrated by the ability of antisense Gklf oligonucleotides to block the production of p21(WAF1/Cip1) in response to p53 activation. Oligonucleotides 140-156 P53 Homo sapiens 49-52 10848610-7 2000 Consistent with our biochemical observations, we show that stimulation of the intracellular cyclic AMP (cAMP) pathway, which leads to CREB phosphorylation, strongly enhances both the transcriptional activation and apoptotic properties of p53. Cyclic AMP 92-102 P53 Homo sapiens 238-241 10848610-7 2000 Consistent with our biochemical observations, we show that stimulation of the intracellular cyclic AMP (cAMP) pathway, which leads to CREB phosphorylation, strongly enhances both the transcriptional activation and apoptotic properties of p53. Cyclic AMP 104-108 P53 Homo sapiens 238-241 10854551-0 2000 Raf-1 kinase activity predicts for paclitaxel resistance in TP53mut, but not TP53wt human ovarian cancer cells. Paclitaxel 35-45 P53 Homo sapiens 60-67 10854551-0 2000 Raf-1 kinase activity predicts for paclitaxel resistance in TP53mut, but not TP53wt human ovarian cancer cells. Paclitaxel 35-45 P53 Homo sapiens 60-64 10854551-7 2000 However, in the ovarian cancer cell lines (CA-OV3, SK-OV3, 2780/CP and OAW42/CP) that have a mutant TP53 (TP53mut), the cytotoxicity induced by 60 nM paclitaxel exhibited the same relationship to Raf-1 kinase activity as previously observed in cervical tumor cell lines. Paclitaxel 150-160 P53 Homo sapiens 100-104 10854551-7 2000 However, in the ovarian cancer cell lines (CA-OV3, SK-OV3, 2780/CP and OAW42/CP) that have a mutant TP53 (TP53mut), the cytotoxicity induced by 60 nM paclitaxel exhibited the same relationship to Raf-1 kinase activity as previously observed in cervical tumor cell lines. Paclitaxel 150-160 P53 Homo sapiens 106-113 10854551-8 2000 These data suggest that the therapeutic efficacy of paclitaxel in ovarian cancer patient whose tumors have TP53mut might be increased if it is administered in combination with Raf-1 kinase inhibitors, e.g., ISIS 5132. Paclitaxel 52-62 P53 Homo sapiens 107-111 10876230-0 2000 Where cancer meets calcium--p53 crosstalk with EF-hands. Calcium 19-26 P53 Homo sapiens 28-31 10918568-0 2000 Spontaneous development of drug resistance: mismatch repair and p53 defects in resistance to cisplatin in human tumor cells. Cisplatin 93-102 P53 Homo sapiens 64-67 10918568-1 2000 The contributions of defective mismatch repair and mutated p53 to cisplatin resistance of human tumor cells were analysed. Cisplatin 66-75 P53 Homo sapiens 59-62 10918568-7 2000 Firstly, separate introduction of a p53 defect into A2780 cells significantly increased their cisplatin resistance; defective hMLH1 provided less extensive protection. Cisplatin 94-103 P53 Homo sapiens 36-39 10918568-9 2000 Both approaches indicate that defective p53 status is a major determinant of cisplatin resistance and defective mismatch repair is a minor, and independent, contributor. Cisplatin 77-86 P53 Homo sapiens 40-43 10871860-0 2000 Paclitaxel selects for mutant or pseudo-null p53 in drug resistance associated with tubulin mutations in human cancer. Paclitaxel 0-10 P53 Homo sapiens 45-48 10871860-2 2000 While the role of p53 in the intrinsic sensitivity of human cancer cells to paclitaxel (PTX) remains controversial, its role in acquired paclitaxel resistance has never been addressed. Paclitaxel 76-86 P53 Homo sapiens 18-21 10871860-3 2000 In this study we examined the p53 status of three paclitaxel selected human ovarian carcinoma sublines, resistant to paclitaxel due to acquired beta-tubulin mutations which impair paclitaxel"s interaction with tubulin. Paclitaxel 50-60 P53 Homo sapiens 30-33 10871860-4 2000 In contrast to parental cells which have wt p53, in all PTX-resistant sublines p53 was functionally inactive. Paclitaxel 56-59 P53 Homo sapiens 44-47 10871860-4 2000 In contrast to parental cells which have wt p53, in all PTX-resistant sublines p53 was functionally inactive. Paclitaxel 56-59 P53 Homo sapiens 79-82 10871860-8 2000 While PTX resistance is primarily conferred by the tubulin mutations, the loss of functional p53 observed in all clones, suggests that this loss may facilitate the development of resistance potentially by providing a clonal advantage which promotes the isolation of paclitaxel resistant cells. Paclitaxel 266-276 P53 Homo sapiens 93-96 10764786-0 2000 The p53 tumor suppressor stimulates the catalytic activity of human topoisomerase IIalpha by enhancing the rate of ATP hydrolysis. Adenosine Triphosphate 115-118 P53 Homo sapiens 4-7 10764786-7 2000 ATP hydrolysis assays revealed that the ATPase activity of topoisomerase IIalpha was specifically enhanced by p53. Adenosine Triphosphate 0-3 P53 Homo sapiens 110-113 10749849-9 2000 The physiological relevance of GKLF in mediating p53-dependent induction of p21(WAF1/Cip1) is demonstrated by the ability of antisense Gklf oligonucleotides to block the production of p21(WAF1/Cip1) in response to p53 activation. Oligonucleotides 140-156 P53 Homo sapiens 214-217 10747897-4 2000 Furthermore, we demonstrate that anisomycin- and tumor necrosis factor-alpha-induced phosphorylation of p53 at Ser-392, which is important for the transcriptional activity of this growth suppressor protein, requires p38 MAP kinase and CK2 activities. Anisomycin 33-43 P53 Homo sapiens 104-107 10866304-0 2000 Alcohol consumption and cigarette smoking increase the frequency of p53 mutations in non-small cell lung cancer. Alcohols 0-7 P53 Homo sapiens 68-71 10866304-6 2000 p53 mutations were more common in patients who used alcohol than in patients who consumed less than one drink per day (72 versus 39%; P = 0.003), and were detected more often smokers than nonsmokers (58% versus 10%, P = 0.02). Alcohols 52-59 P53 Homo sapiens 0-3 10866304-7 2000 Mutations in the p53 gene were present more often (P = 0.01) in alcohol drinkers who smoked cigarettes [76% (31 of 41)], than in nondrinkers (<1 drink per day) who smoked cigarettes [42% (20 of 48)] or in nondrinkers who did not smoke [14% (1 of 7)]. Alcohols 64-71 P53 Homo sapiens 17-20 10866304-8 2000 In conclusion, alcohol consumption and tobacco use are both associated with p53 mutations in non-small cell lung cancer. Alcohols 15-22 P53 Homo sapiens 76-79 10866304-9 2000 The link between exposure to both alcohol and tobacco and p53 mutations raises the possibility that alcohol may enhance the mutagenic effects of cigarette smoke in the lung. Alcohols 34-41 P53 Homo sapiens 58-61 10866304-9 2000 The link between exposure to both alcohol and tobacco and p53 mutations raises the possibility that alcohol may enhance the mutagenic effects of cigarette smoke in the lung. Alcohols 100-107 P53 Homo sapiens 58-61 10828488-9 2000 However, high concentrations of exogenous ROS can also stimulate smooth muscle cell apoptosis as shown for other cell types probably via activation of p53. Reactive Oxygen Species 42-45 P53 Homo sapiens 151-154 10747897-4 2000 Furthermore, we demonstrate that anisomycin- and tumor necrosis factor-alpha-induced phosphorylation of p53 at Ser-392, which is important for the transcriptional activity of this growth suppressor protein, requires p38 MAP kinase and CK2 activities. Serine 111-114 P53 Homo sapiens 104-107 10911952-9 2000 By inducing premature senescence with a pulse treatment of H2O2, we can study the role of the cell cycle checkpoint proteins p53, p21, p16 and Rb in gaining each feature of senescence.

Alcohols 0-7 P53 Homo sapiens 75-78 10864201-0 2000 ATM protein and p53-serine 15 phosphorylation in ataxia-telangiectasia (AT) patients and at heterozygotes. Serine 20-26 P53 Homo sapiens 16-19 10839309-2 2000 A significantly larger proportion of heavy alcohol drinkers and cigarette smokers was evident in the p53-positive group. Alcohols 43-50 P53 Homo sapiens 101-104 10864201-6 2000 The radiation-induced phosphorylation of p53 protein at serine 15, largely mediated by ATM kinase, was defective in AT, A(-T) and in 2/4 heterozygous carriers, while the G1 cell cycle checkpoint was disrupted in all AT and A(-T) cases, and in 3/10 AT heterozygotes.

Cisplatin 10-19 P53 Homo sapiens 155-158 10850407-2 2000 The arginine allele at codon 72 of p53 was found to be more susceptible to degradation by HPV E6 protein than is the proline allele in vivo, thus resulting in a high frequency of cervical SCC in individuals homozygous for arginine at the codon. Arginine 4-12 P53 Homo sapiens 35-38 10850407-2 2000 The arginine allele at codon 72 of p53 was found to be more susceptible to degradation by HPV E6 protein than is the proline allele in vivo, thus resulting in a high frequency of cervical SCC in individuals homozygous for arginine at the codon. Arginine 222-230 P53 Homo sapiens 35-38 10941537-8 2000 Pre-exposure to cisPt based chemotherapy appears to result in the emergence of cisPt resistance, elevated intracellular GSH levels as well as p53 positivity. Cisplatin 16-21 P53 Homo sapiens 142-145 10897215-7 2000 Furthermore, significant statistical differences in chemosensitivity to 5-FU and CDDP were revealed depending on the presence of serum p53 antibodies. Fluorouracil 72-76 P53 Homo sapiens 135-138 10850547-2 2000 A novel polymerase chain reaction (PCR) approach for the analysis of the entire p53 coding and splice site regions from microdissected, formalin-fixed, paraffin-embedded tumor tissues has been developed which allows multiple genetic analyses to be performed from one primary amplification reaction. Paraffin 152-160 P53 Homo sapiens 80-83 10897215-7 2000 Furthermore, significant statistical differences in chemosensitivity to 5-FU and CDDP were revealed depending on the presence of serum p53 antibodies. cddp 81-85 P53 Homo sapiens 135-138 10842159-10 2000 CONCLUSION: Nitric oxide inhibits VSMC proliferation in association with the upregulation of p21; both occur independent of p53 and cGMP while being partially mediated through the p42/44 MAPK signaling cascade. Nitric Oxide 12-24 P53 Homo sapiens 124-127 10838140-4 2000 A disproportionally high number of mutations in p53 (and other genes) are found at methylated CpG dinucleotides. cytidylyl-3'-5'-guanosine 94-111 P53 Homo sapiens 48-51 10874665-6 2000 Mdm2 and p53 were demonstrated by immunohistology on formalin-fixed and paraffin-embedded tumor tissue. Paraffin 72-80 P53 Homo sapiens 9-12 10897337-3 2000 This is a highly selective approach, whereby immunostained sections of formalin fixed, paraffin wax embedded tissue are exposed to ultraviolet irradiation to damage the DNA in p53 negative cells. Paraffin 87-99 P53 Homo sapiens 176-179 10825186-2 2000 Using three cell model systems, each isogenic, we showed that either ectopic or endogenous p53 sustained a G(2) arrest activated by ionizing radiation or adriamycin. Doxorubicin 154-164 P53 Homo sapiens 91-94 11032762-3 2000 The purpose of this study was to examine whether p53 Arg at the polymorphic position 72 could represent a risk factor for women with breast lesions. Arginine 53-56 P53 Homo sapiens 49-52 11032762-7 2000 The allele frequency of p53 Arg/Arg was much higher than that of the normal samples (61% versus 20%). Arginine 28-31 P53 Homo sapiens 24-27 11032762-7 2000 The allele frequency of p53 Arg/Arg was much higher than that of the normal samples (61% versus 20%). Arginine 32-35 P53 Homo sapiens 24-27 11032762-8 2000 Based on the findings of this study, it is suggested that p53 Arg homozygosity could represent a risk factor for the tumorigenesis of the breast.

Tamoxifen 153-162 P53 Homo sapiens 14-18 10786695-9 2000 Furthermore, p53-Mut and p53-Null cells were more sensitive than p53-WT cells and displayed increased levels of anti-BPDE-induced apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 117-121 P53 Homo sapiens 13-16 10786695-9 2000 Furthermore, p53-Mut and p53-Null cells were more sensitive than p53-WT cells and displayed increased levels of anti-BPDE-induced apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 117-121 P53 Homo sapiens 25-28 10786679-8 2000 In multivariate analysis for response including the classical parameters age and menopausal status, disease-free interval, dominant site of relapse, and levels of estrogen receptor and progesterone receptor, TP53 mutation was a significant predictor of poor response in the tamoxifen-treated group (OR, 0.29; 95% CI, 0.13-0.63; P = 0.0014). Tamoxifen 274-283 P53 Homo sapiens 208-212 10786695-9 2000 Furthermore, p53-Mut and p53-Null cells were more sensitive than p53-WT cells and displayed increased levels of anti-BPDE-induced apoptosis. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 117-121 P53 Homo sapiens 25-28 10786679-10 2000 Interestingly, the response of patients with TP53 mutations to chemotherapy after tamoxifen was not worse than that of patients without these mutations (50% versus 42%; OR, 1.35, nonsignificant). Tamoxifen 82-91 P53 Homo sapiens 45-49 10786695-10 2000 Thus, wild-type p53 is required for the efficient global genomic repair of anti-BPDE-induced DNA adducts from the overall genome, but not for transcription-coupled repair of actively transcribed genes. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 80-84 P53 Homo sapiens 16-19 10786679-11 2000 The median progression-free survival after systemic treatment was shorter for patients with a TP53 mutation than for patients with wild-type TP53 (6.6 and 0.6 months less for tamoxifen and up-front chemotherapy, respectively). Tamoxifen 175-184 P53 Homo sapiens 94-98 10786679-12 2000 In conclusion, TP53 gene mutation of the primary tumor is helpful in predicting the response of patients with metastatic breast disease to tamoxifen therapy. Tamoxifen 139-148 P53 Homo sapiens 15-19 10753954-7 2000 Rapamycin blocked p70(S6k) phosphorylation induced by NO and also inhibited p53 phosphorylation and p21 expression whereas PD98059 only prevented the NO-induced increase in p21 protein without influencing either p53 activation or p21 mRNA expression.

Paraffin 201-209 P53 Homo sapiens 103-106 10647890-2 1999 A common p53 polymorphism at codon-72 of exon 4 results in translation to either arginine or proline. Arginine 81-89 P53 Homo sapiens 9-12 10629550-1 1999 In breast cancer, mutations located in the zinc-binding functional domains of the p53 gene have been reported to predict a worse prognosis and a worse response to treatment with doxorubicin, compared with mutations in other parts within exons 5-8 of the gene. Doxorubicin 178-189 P53 Homo sapiens 82-85 10567656-12 1999 There was no difference in the distribution of p53 proline and arginine alleles between HPV-16-positive cervical carcinoma patients and local controls, and no influence on clinical outcome; however, there was a trend for an increased frequency of p53 arginine homozygotes among the 350T carcinoma patients. Arginine 251-259 P53 Homo sapiens 247-250 10568814-0 1999 Cisplatin-induced p53-independent growth arrest and cell death in cancer cells. Cisplatin 0-9 P53 Homo sapiens 18-21 10568814-5 1999 These findings provide further evidence that cells carrying mutations resulting in loss of function in the p53 gene can be killed by cisplatin via a p53-independent route with some similarities to replicative senescence, but not apoptosis. Cisplatin 133-142 P53 Homo sapiens 107-110 10568814-5 1999 These findings provide further evidence that cells carrying mutations resulting in loss of function in the p53 gene can be killed by cisplatin via a p53-independent route with some similarities to replicative senescence, but not apoptosis. Cisplatin 133-142 P53 Homo sapiens 149-152 10569615-0 1999 Synergistic enhancement of resistance to cisplatin in human bladder cancer cells by overexpression of mutant-type p53 and Bcl-2. Cisplatin 41-50 P53 Homo sapiens 114-117 10569615-1 1999 PURPOSE: The objective of this study was to characterize the effect of mutant-type p53 and Bcl-2 expression on the sensitivity to cisplatin in a human bladder cancer cell line both in vitro and in vivo. Cisplatin 130-139 P53 Homo sapiens 83-86 10569615-3 1999 The effects of the overexpression of mutant-type p53, Bcl-2, or both on the sensitivity to cisplatin and the apoptotic features in vitro were evaluated by the MTT assay, staining with Hoechst 33258 and a DNA fragmentation assay. Cisplatin 91-100 P53 Homo sapiens 49-52 10569615-5 1999 RESULTS: The introduction of mutant-type p53 or Bcl-2 conferred resistance to cisplatin on KoTCC-1 cells through the inhibition of apoptosis. Cisplatin 78-87 P53 Homo sapiens 41-44 10569615-7 1999 Furthermore, the KoTCC-1 cells transfected with both mutant-type p53 and Bcl-2 exhibited significantly higher resistance to cisplatin treatment than cells transfected with mutant-type p53 or Bcl-2 alone in experimental models in vivo. Cisplatin 124-133 P53 Homo sapiens 65-68 10569615-7 1999 Furthermore, the KoTCC-1 cells transfected with both mutant-type p53 and Bcl-2 exhibited significantly higher resistance to cisplatin treatment than cells transfected with mutant-type p53 or Bcl-2 alone in experimental models in vivo. Cisplatin 124-133 P53 Homo sapiens 184-187 10665656-0 1999 Cisplatin-resistant HeLa cells are resistant to apoptosis via p53-dependent and -independent pathways. Cisplatin 0-9 P53 Homo sapiens 62-65 10569615-8 1999 CONCLUSIONS: These findings suggest that the overexpression of both mutant-type p53 and Bcl-2 in bladder cancer cells synergistically interferes with the therapeutic effect of cisplatin through the inhibition of the apoptotic pathway. Cisplatin 176-185 P53 Homo sapiens 80-83 10665656-7 1999 Transfection of wild-type p53 gene enhanced the cytotoxicity of cisplatin and cisplatin-induced apoptosis in HeLa cells but not in HeLa/CDDP cells, although it caused p53 overexpression in both cell lines. Cisplatin 64-73 P53 Homo sapiens 26-29 10544021-3 1999 In the present study, we showed that the topoisomerase II inhibitor of widely used anticancer drugs etoposide and doxorubicin activated wt p53 in BL2, a Burkitt"s lymphoma cell line which overexpressed MDM2. Doxorubicin 114-125 P53 Homo sapiens 139-142 10665656-7 1999 Transfection of wild-type p53 gene enhanced the cytotoxicity of cisplatin and cisplatin-induced apoptosis in HeLa cells but not in HeLa/CDDP cells, although it caused p53 overexpression in both cell lines. Cisplatin 78-87 P53 Homo sapiens 26-29 10665656-10 1999 p53 gene transfection did not affect the extent of DNA fragmentation in either cell line, suggesting that paclitaxel may induce p53-independent apoptosis. Paclitaxel 106-116 P53 Homo sapiens 128-131 10628802-1 1999 TP53 and MDM2 genes and their protein expression were evaluated in frozen and paraffin-embedded tissue from 27 patients with malignant fibrous histiocytoma to elucidate the relationship between them, their implication in tumor progression mechanisms and their possible diagnostic-prognostic value in malignant fibrous histiocytoma. Paraffin 78-86 P53 Homo sapiens 0-4 10551826-4 1999 To characterize further the function of these two domains, we demonstrate in this report that the previously described major nuclear localization signal works together with Lys(305)-Arg(306) to form a bipartite and functional nuclear localization sequence (NLS) for p53 nuclear import. Lysine 173-176 P53 Homo sapiens 266-269 10551826-4 1999 To characterize further the function of these two domains, we demonstrate in this report that the previously described major nuclear localization signal works together with Lys(305)-Arg(306) to form a bipartite and functional nuclear localization sequence (NLS) for p53 nuclear import. Arginine 182-185 P53 Homo sapiens 266-269 10661763-4 1999 In this model, TAM resistance resulted in an increase in the detectable basal levels of cyclin E, GADD 153, p16, BAX, Bcl-XL, and wild-type and mutant p53, an increase in TAM induction of p16, and a decrease in the detectable basal levels of cyclin D1, p21 and p27. Tamoxifen 15-18 P53 Homo sapiens 151-154 10935502-0 1999 p53-independent inhibition of proliferation and p21(WAF1/Cip1)-modulated induction of cell death by the antioxidants N-acetylcysteine and vitamin E. Acetylcysteine 117-133 P53 Homo sapiens 0-3 10935502-5 1999 The antioxidants, N-acetylcysteine (NAC) and vitamin E either inhibited proliferation in a p53-independent manner without affecting cell viability or induced cell death. Acetylcysteine 18-34 P53 Homo sapiens 91-94 10935502-5 1999 The antioxidants, N-acetylcysteine (NAC) and vitamin E either inhibited proliferation in a p53-independent manner without affecting cell viability or induced cell death. Acetylcysteine 36-39 P53 Homo sapiens 91-94 10570149-0 1999 Phosphorylation of Ser-20 mediates stabilization of human p53 in response to DNA damage. Serine 19-22 P53 Homo sapiens 58-61 10570149-3 1999 The ATM and ATR kinases, whose activation in response to ionizing radiation (IR) and UV light, respectively, is required for p53 stabilization, directly phosphorylate p53 on Ser-15. Serine 174-177 P53 Homo sapiens 125-128 10570149-3 1999 The ATM and ATR kinases, whose activation in response to ionizing radiation (IR) and UV light, respectively, is required for p53 stabilization, directly phosphorylate p53 on Ser-15. Serine 174-177 P53 Homo sapiens 167-170 10570149-4 1999 However, phosphorylation of Ser-15 is critical for the apoptotic activity of p53 and not for p53 stabilization. Serine 28-31 P53 Homo sapiens 77-80 10570149-6 1999 We analyzed the IR- and UV light-induced stabilization of p53 proteins with substitutions of Ser known to be posttranslationally modified after DNA damage. Serine 93-96 P53 Homo sapiens 58-61 10570149-8 1999 Furthermore, both IR and UV light induced phosphorylation of p53 on Ser-20, which involved the majority of nuclear p53 protein and weakened the interaction of p53 with Mdm2 in vitro. Serine 68-71 P53 Homo sapiens 61-64 10570149-8 1999 Furthermore, both IR and UV light induced phosphorylation of p53 on Ser-20, which involved the majority of nuclear p53 protein and weakened the interaction of p53 with Mdm2 in vitro. Serine 68-71 P53 Homo sapiens 115-118 10570149-8 1999 Furthermore, both IR and UV light induced phosphorylation of p53 on Ser-20, which involved the majority of nuclear p53 protein and weakened the interaction of p53 with Mdm2 in vitro. Serine 68-71 P53 Homo sapiens 115-118 10570149-10 1999 We therefore propose that ATM and ATR activate an, as yet unidentified, kinase that stabilizes p53 by phosphorylating it on Ser-20. Serine 124-127 P53 Homo sapiens 95-98 10597277-8 1999 We show directly that, like ATM and DNA-PK, ATR phosphorylates the genome surveillance protein p53 on serine 15, a site which is up-regulated in response to DNA damage. Serine 102-108 P53 Homo sapiens 95-98 10562558-3 1999 A lysine residue at amino acid position 386 of p53 is required for this previously undescribed modification, strongly suggesting that this lysine residue serves as the major attachment site for SUMO-1. Lysine 2-8 P53 Homo sapiens 47-50 10562558-3 1999 A lysine residue at amino acid position 386 of p53 is required for this previously undescribed modification, strongly suggesting that this lysine residue serves as the major attachment site for SUMO-1. Lysine 139-145 P53 Homo sapiens 47-50 10597241-0 1999 p53 accumulation in apoptotic macrophages is an energy demanding process that precedes cytochrome c release in response to nitric oxide. Nitric Oxide 123-135 P53 Homo sapiens 0-3 10597241-4 1999 S-nitrosoglutathione and spermine-NO caused a fast p53 accumulation, followed by Bcl-xL downregulation, Cyt c release, and caspase activation. S-Nitrosoglutathione 0-20 P53 Homo sapiens 51-54 10597241-4 1999 S-nitrosoglutathione and spermine-NO caused a fast p53 accumulation, followed by Bcl-xL downregulation, Cyt c release, and caspase activation. spermine-no 25-36 P53 Homo sapiens 51-54 10597241-11 1999 Moreover, pulse-chase-experiments in combination with the ATP-depletion protocol identified p53 accumulation and stabilization as an energy requiring process. Adenosine Triphosphate 58-61 P53 Homo sapiens 92-95 10597241-12 1999 This allowed to dissect two ATP-dependent steps, one is in association with Apaf-1 formation, while the other resides in p53 accumulation. Adenosine Triphosphate 28-31 P53 Homo sapiens 121-124 10597242-3 1999 Thus GM glioblastoma cells carrying an inducible MMTV-driven p53 gene undergo cell cycle arrest and upregulate p21 but not KILLER/DR5 expression upon dexamethasone exposure. Dexamethasone 150-163 P53 Homo sapiens 61-64 10619896-6 1999 A correlation was found between alcohol intake and p53 expression. Alcohols 32-39 P53 Homo sapiens 51-54 10544021-5 1999 Activation of p53 was accompanied by phosphorylation of p53 at Ser-15 and elevated p21 and MDM2, both of which were at least partly blocked by wortmannin, a kinase inhibitor against proteins with a PI3 kinase domain. Serine 63-66 P53 Homo sapiens 14-17 10544021-5 1999 Activation of p53 was accompanied by phosphorylation of p53 at Ser-15 and elevated p21 and MDM2, both of which were at least partly blocked by wortmannin, a kinase inhibitor against proteins with a PI3 kinase domain. Serine 63-66 P53 Homo sapiens 56-59 10544021-8 1999 This p53 was co-immunoprecipitated with MDM2, but p53 activated by etoposide or doxorubicin barely complexed with MDM2. Doxorubicin 80-91 P53 Homo sapiens 50-53 10697561-5 1999 The identification of DNA-fragmentation and p53 and Ki-67 genes expression suggest that the mechanism of NADH action is different from disregulation of genes considered as check-points in cell cycle. NAD 105-109 P53 Homo sapiens 44-47 10697517-0 1999 Effect of paclitaxel pretreatment on radiation-induced p53-dependent apoptosis. Paclitaxel 10-20 P53 Homo sapiens 55-58 10697517-1 1999 The aim of this study was to investigate the effect of paclitaxel on radiation-induced p53-dependent apoptosis. Paclitaxel 55-65 P53 Homo sapiens 87-90 10527691-0 1999 Curcumin causes the growth arrest and apoptosis of B cell lymphoma by downregulation of egr-1, c-myc, bcl-XL, NF-kappa B, and p53. Curcumin 0-8 P53 Homo sapiens 126-129 10697517-9 1999 The present study indicates that p53-dependent apoptosis was frequently induced in the human tumor in vivo by irradiation, but not by paclitaxel alone. Paclitaxel 134-144 P53 Homo sapiens 33-36 10697522-0 1999 De novo deletions of p53 gene and wild-type p53 correlate with acquired cisplatin-resistance in human osteosarcoma OST cell line. Cisplatin 72-81 P53 Homo sapiens 21-24 10697522-0 1999 De novo deletions of p53 gene and wild-type p53 correlate with acquired cisplatin-resistance in human osteosarcoma OST cell line. Cisplatin 72-81 P53 Homo sapiens 44-47 10697522-2 1999 We investigated the relationship between p53 status and the development of resistance to cisplatin in osteosarcoma cell lines. Cisplatin 89-98 P53 Homo sapiens 41-44 10697522-9 1999 Furthermore, p53 induction was lost in OST/R cells after cisplatin exposure. Cisplatin 57-66 P53 Homo sapiens 13-16 10697522-10 1999 CONCLUSIONS: De novo deletions of the p53 gene and wild-type p53 were associated with the acquisition of cisplatin-resistance in osteosarcoma. Cisplatin 105-114 P53 Homo sapiens 38-41 10697522-10 1999 CONCLUSIONS: De novo deletions of the p53 gene and wild-type p53 were associated with the acquisition of cisplatin-resistance in osteosarcoma. Cisplatin 105-114 P53 Homo sapiens 61-64 10674873-3 1999 Repair of cisplatin-induced DNA damage was reduced in MCF7 cells overexpressing Mdm2, compared to MCF7 cells in which wild-type p53 function was intact. Cisplatin 10-19 P53 Homo sapiens 128-131 10674873-6 1999 MCF7 cells with intact wild-type p53, on the other hand, arrested primarily in G2/M phase after cisplatin treatment. Cisplatin 96-105 P53 Homo sapiens 33-36 10674873-7 1999 These findings indicate that Mdm2 overexpression can recapitulate the effect of p53 mutations on DNA repair of cisplatin lesions. Cisplatin 111-120 P53 Homo sapiens 80-83 10527691-5 1999 Furthermore, curcumin downregulated the expression of survival genes egr-1, c-myc, and bcl-X(L) as well as the tumor suppressor gene p53 in B cells. Curcumin 13-21 P53 Homo sapiens 133-136 10545114-0 1999 p53 regulates mitochondrial membrane potential through reactive oxygen species and induces cytochrome c-independent apoptosis blocked by Bcl-2. Reactive Oxygen Species 55-78 P53 Homo sapiens 0-3 10589764-0 1999 TP53 accumulation predicts improved survival in patients resistant to systemic cisplatin-based chemotherapy for muscle-invasive bladder cancer. Cisplatin 79-88 P53 Homo sapiens 0-4 10545114-8 1999 p53 induced ROS generation, which then caused a transient increase of Deltapsi followed by a decrease. Reactive Oxygen Species 12-15 P53 Homo sapiens 0-3 10545114-12 1999 Thus, the ROS-mediated disruption of Deltapsi constitutes a pivotal step in the apoptotic pathway of p53, and this pathway does not involve cytochrome c release. Reactive Oxygen Species 10-13 P53 Homo sapiens 101-104 10626170-4 1999 METHODOLOGY: In a retrospective case-series p53 expression was assessed using standard immunohistochemical methods in the paraffin-embedded specimens of 45 liver resections for colorectal metastases, performed in 43 patients in a single institution between "86 and "96. Paraffin 122-130 P53 Homo sapiens 44-47 10527623-2 1999 We examined the in vitro effects of CD437 and found that CD437 induces S phase arrest within 24 to 48 h, followed by cell death, in the p53-negative Hep3B and the p53-positive HepG2 human hepatoma cell lines. CD 437 57-62 P53 Homo sapiens 136-139 10527623-2 1999 We examined the in vitro effects of CD437 and found that CD437 induces S phase arrest within 24 to 48 h, followed by cell death, in the p53-negative Hep3B and the p53-positive HepG2 human hepatoma cell lines. CD 437 57-62 P53 Homo sapiens 163-166 10518116-8 1999 The expression of the proteins of the protooncogene Bcl-2 and the tumor suppressor gene p53 following staurosporine or retinoic acid treatment was assessed by Western blot and immunocytochemistry. Tretinoin 119-132 P53 Homo sapiens 88-91 10534572-11 1999 Moreover, up-regulation of p53 and down-regulation of Bcl-2 was observed only in HPAC cells treated with Taxol. Paclitaxel 105-110 P53 Homo sapiens 27-30 10502297-2 1999 The stable expression of wild-type p53 resulted in a significant increase in sensitivity to the topoisomerase II poisons etoposide and doxorubicin, but not to the topoisomerase II inhibitors razoxane and ADR-529. Doxorubicin 135-146 P53 Homo sapiens 35-38 10518116-10 1999 The opposite alteration of Bcl-2 (anti-apoptotic) and p53 (apoptotic) contents in SH-SY5Y cells with retinoic acid and staurosporine are attributed to the changes in cell vulnerability. Tretinoin 101-114 P53 Homo sapiens 54-57 10518116-9 1999 Retinoic acid increased Bcl-2 and decreased p53 levels, whereas staurosporine decreased Bcl-2 and increased p53 levels. Tretinoin 0-13 P53 Homo sapiens 44-47 10523638-0 1999 An ATP/ADP-dependent molecular switch regulates the stability of p53-DNA complexes. Adenosine Triphosphate 3-6 P53 Homo sapiens 65-68 10516009-3 1999 Previous studies showed that the EBV-encoded immediate-early transcription factor, Zta, can induce expression of the cyclin-dependent kinase inhibitors, p21 and p27, the tumor suppressor, p53, and cell growth arrest. zta 83-86 P53 Homo sapiens 188-191 10516009-5 1999 Here we show that substitution of Zta"s basic DNA binding domain with the analogous region of the Zta homologue, c-Fos, abrogates Zta"s ability to induce growth arrest and to induce p21, p27, or p53 expression, suggesting that protein-protein interactions between this region of Zta and key cell cycle control proteins are involved in signaling cell cycle arrest. zta 34-37 P53 Homo sapiens 195-198 10516009-5 1999 Here we show that substitution of Zta"s basic DNA binding domain with the analogous region of the Zta homologue, c-Fos, abrogates Zta"s ability to induce growth arrest and to induce p21, p27, or p53 expression, suggesting that protein-protein interactions between this region of Zta and key cell cycle control proteins are involved in signaling cell cycle arrest. zta 98-101 P53 Homo sapiens 195-198 10516009-5 1999 Here we show that substitution of Zta"s basic DNA binding domain with the analogous region of the Zta homologue, c-Fos, abrogates Zta"s ability to induce growth arrest and to induce p21, p27, or p53 expression, suggesting that protein-protein interactions between this region of Zta and key cell cycle control proteins are involved in signaling cell cycle arrest. zta 98-101 P53 Homo sapiens 195-198 10516009-5 1999 Here we show that substitution of Zta"s basic DNA binding domain with the analogous region of the Zta homologue, c-Fos, abrogates Zta"s ability to induce growth arrest and to induce p21, p27, or p53 expression, suggesting that protein-protein interactions between this region of Zta and key cell cycle control proteins are involved in signaling cell cycle arrest. zta 98-101 P53 Homo sapiens 195-198 10516009-7 1999 Last, we provide evidence that Zta-mediated inductions of p21, p27, and p53 occur, at least in part, through distinct pathways. zta 31-34 P53 Homo sapiens 72-75 10523638-0 1999 An ATP/ADP-dependent molecular switch regulates the stability of p53-DNA complexes. Adenosine Diphosphate 7-10 P53 Homo sapiens 65-68 10531402-0 1999 Modulation of cisplatinum cytotoxicity by p53: effect of p53-mediated apoptosis and DNA repair. Cisplatin 14-25 P53 Homo sapiens 42-45 10531402-0 1999 Modulation of cisplatinum cytotoxicity by p53: effect of p53-mediated apoptosis and DNA repair. Cisplatin 14-25 P53 Homo sapiens 57-60 10523638-2 1999 We now show, for the first time, that the interaction of p53 with DNA can be stabilized by small molecules, such as ADP and dADP. Adenosine Diphosphate 116-119 P53 Homo sapiens 57-60 10523638-3 1999 Our results also indicate an ATP/ADP molecular switch mechanism which determines the off-on states for p53-DNA binding. Adenosine Triphosphate 29-32 P53 Homo sapiens 103-106 10523638-3 1999 Our results also indicate an ATP/ADP molecular switch mechanism which determines the off-on states for p53-DNA binding. Adenosine Diphosphate 33-36 P53 Homo sapiens 103-106 10523638-4 1999 This ATP/ADP molecular switch requires dimer-dimer interaction of the p53 tetramer. Adenosine Triphosphate 5-8 P53 Homo sapiens 70-73 10523638-4 1999 This ATP/ADP molecular switch requires dimer-dimer interaction of the p53 tetramer. Adenosine Diphosphate 9-12 P53 Homo sapiens 70-73 10523638-5 1999 Dissociation of p53-DNA complexes by ATP is independent of ATP hydrolysis. Adenosine Triphosphate 37-40 P53 Homo sapiens 16-19 10523638-6 1999 Low-level ATPase activity is nonetheless associated with ATP-p53 interaction and may serve to regenerate ADP-p53, thus recycling the high-affinity DNA binding form of p53. Adenosine Diphosphate 105-108 P53 Homo sapiens 61-64 10523638-6 1999 Low-level ATPase activity is nonetheless associated with ATP-p53 interaction and may serve to regenerate ADP-p53, thus recycling the high-affinity DNA binding form of p53. Adenosine Diphosphate 105-108 P53 Homo sapiens 109-112 10523638-6 1999 Low-level ATPase activity is nonetheless associated with ATP-p53 interaction and may serve to regenerate ADP-p53, thus recycling the high-affinity DNA binding form of p53. Adenosine Diphosphate 105-108 P53 Homo sapiens 109-112 10523638-7 1999 The ATP/ADP regulatory mechanism applies to two distinct types of p53 interaction with DNA, namely, sequence-specific DNA binding (via the core domain of the p53 protein) and binding to sites of DNA damage (via the C-terminal domain). Adenosine Triphosphate 4-7 P53 Homo sapiens 66-69 10523638-7 1999 The ATP/ADP regulatory mechanism applies to two distinct types of p53 interaction with DNA, namely, sequence-specific DNA binding (via the core domain of the p53 protein) and binding to sites of DNA damage (via the C-terminal domain). Adenosine Triphosphate 4-7 P53 Homo sapiens 158-161 10523638-7 1999 The ATP/ADP regulatory mechanism applies to two distinct types of p53 interaction with DNA, namely, sequence-specific DNA binding (via the core domain of the p53 protein) and binding to sites of DNA damage (via the C-terminal domain). Adenosine Diphosphate 8-11 P53 Homo sapiens 66-69 10523638-7 1999 The ATP/ADP regulatory mechanism applies to two distinct types of p53 interaction with DNA, namely, sequence-specific DNA binding (via the core domain of the p53 protein) and binding to sites of DNA damage (via the C-terminal domain). Adenosine Diphosphate 8-11 P53 Homo sapiens 158-161 10523638-8 1999 Further studies indicate that ADP not only stabilizes p53-DNA complexes but also renders the complexes susceptible to dissociation by specific p53 binding proteins. Adenosine Diphosphate 30-33 P53 Homo sapiens 54-57 10523638-8 1999 Further studies indicate that ADP not only stabilizes p53-DNA complexes but also renders the complexes susceptible to dissociation by specific p53 binding proteins.

Cisplatin 62-71 P53 Homo sapiens 111-114 10471039-8 1999 The results showed that the transfer of functional p53 resulted in a marked (tenfold) reduction of cellular chemosensitivity to the multinuclear platinum complex but in a moderate sensitization to cisplatin. Platinum 145-153 P53 Homo sapiens 51-54 10471039-8 1999 The results showed that the transfer of functional p53 resulted in a marked (tenfold) reduction of cellular chemosensitivity to the multinuclear platinum complex but in a moderate sensitization to cisplatin. Cisplatin 197-206 P53 Homo sapiens 51-54 10441517-6 1999 Our results suggest a possible connection between p53-dependent apoptosis and the production of reactive oxygen species.

Taxoids 81-88 P53 Homo sapiens 97-100 10446957-8 1999 As a result, we detected enhanced phosphorylation of p53 Ser-18, which corresponds to Ser-15 of human p53, and significant expression of p21 and mdm2 following ionizing radiation.

Serine 57-60 P53 Homo sapiens 102-105 10446979-6 1999 Increased expression of MAP4, which occurs when p53 is transcriptionally inactive, increases microtubule polymerization, paclitaxel binding, and sensitivity to paclitaxel, a drug that stabilizes polymerized microtubules. Paclitaxel 160-170 P53 Homo sapiens 48-51 10446957-8 1999 As a result, we detected enhanced phosphorylation of p53 Ser-18, which corresponds to Ser-15 of human p53, and significant expression of p21 and mdm2 following ionizing radiation.

Doxorubicin 31-42 P53 Homo sapiens 63-66 10615232-1 1999 This retrospective study of ovarian cancer aimed to elucidate whether expression of apoptosis-related proteins, bcl-2, p53 or MDM-2, is associated with resistance to chemotherapy, especially cisplatin (CDDP) based chemotherapy. Cisplatin 191-200 P53 Homo sapiens 119-122 10446993-2 1999 Moderate doses of doxorubicin induced this senescence-like phenotype (SLP) in 11 of 14 tested cell lines derived from different types of human solid tumors, including all of the lines with wild-type p53 and half of p53-mutated cell lines. Doxorubicin 18-29 P53 Homo sapiens 199-202 10446993-2 1999 Moderate doses of doxorubicin induced this senescence-like phenotype (SLP) in 11 of 14 tested cell lines derived from different types of human solid tumors, including all of the lines with wild-type p53 and half of p53-mutated cell lines.

Arginine 89-92 P53 Homo sapiens 141-144 10604188-3 1999 The p53 protein is a metal-binding transcription factor that is inactivated by metal chelation and by oxidation in vitro. Metals 21-26 P53 Homo sapiens 4-7 10604188-3 1999 The p53 protein is a metal-binding transcription factor that is inactivated by metal chelation and by oxidation in vitro. Metals 79-84 P53 Homo sapiens 4-7 10604188-4 1999 In intact cells, p53 protein activity is crucially dependent on the availability of Zn ions and is impaired by exposure to Cd, a metal which readily substitutes for Zn in a number of transcription factors. Zinc 84-86 P53 Homo sapiens 17-20 10604188-4 1999 In intact cells, p53 protein activity is crucially dependent on the availability of Zn ions and is impaired by exposure to Cd, a metal which readily substitutes for Zn in a number of transcription factors. Cadmium 123-125 P53 Homo sapiens 17-20 10604188-4 1999 In intact cells, p53 protein activity is crucially dependent on the availability of Zn ions and is impaired by exposure to Cd, a metal which readily substitutes for Zn in a number of transcription factors. Metals 129-134 P53 Homo sapiens 17-20 10604188-4 1999 In intact cells, p53 protein activity is crucially dependent on the availability of Zn ions and is impaired by exposure to Cd, a metal which readily substitutes for Zn in a number of transcription factors. Zinc 165-167 P53 Homo sapiens 17-20 10604188-5 1999 Inactivation by Cd suppresses the p53-dependent responses to DNA damage. Cadmium 16-18 P53 Homo sapiens 34-37 10604188-6 1999 Overall, these findings indicate that regulation by metals plays an important role in the control of p53, and that perturbation of this control may explain the carcinogenic potential of several metal compounds. Metals 52-57 P53 Homo sapiens 101-104 10421546-0 1999 Paclitaxel sensitivity correlates with p53 status and DNA fragmentation, but not G2/M accumulation. Paclitaxel 0-10 P53 Homo sapiens 39-42 10421546-3 1999 Although initial studies demonstrated that various DNA-damaging agents can induce p53, more recent studies have also shown p53 induction following nonDNA-damaging agents, including paclitaxel. Paclitaxel 181-191 P53 Homo sapiens 123-126 10421546-10 1999 RESULTS: A 4-fold increase in paclitaxel sensitivity was observed among RKO cells deficient in p53 function compared with wild-type RKO cells (IC 50: 4 nM, 1 nM, 1nM for RKO, RKO.p53.13, RC 10.3, respectively). Paclitaxel 30-40 P53 Homo sapiens 95-98 10421546-10 1999 RESULTS: A 4-fold increase in paclitaxel sensitivity was observed among RKO cells deficient in p53 function compared with wild-type RKO cells (IC 50: 4 nM, 1 nM, 1nM for RKO, RKO.p53.13, RC 10.3, respectively). Paclitaxel 30-40 P53 Homo sapiens 179-182 10517975-8 1999 For example, exposure to ultraviolet light is correlated with transition mutations at dipyrimidine sites; aflatoxin B(1) exposure is correlated with a G:C to T:A transversion that leads to a serine substitution at residue 249 of p53 in hepatocellular carcinoma; and exposure to cigarette smoke is correlated with G:C to T:A transversions in lung carcinoma. Serine 191-197 P53 Homo sapiens 229-232 10421546-11 1999 The increased cytotoxic effect in RKO cells with inactive p53 correlated with an increased propensity towards micronucleation and DNA fragmentation following paclitaxel treatment. Paclitaxel 158-168 P53 Homo sapiens 58-61 10421546-13 1999 CONCLUSIONS: RKO cells lacking functional p53 demonstrate significantly enhanced sensitivity to paclitaxel compared with that of wild-type RKO cells. Paclitaxel 96-106 P53 Homo sapiens 42-45 10413457-4 1999 PP5 has no apparent effect on the binding of hormone to the GR, and dexamethasone-mediated growth arrest correlates with an increase in p53 phosphorylation. Dexamethasone 68-81 P53 Homo sapiens 136-139 10421546-15 1999 Although previous published reports of enhanced paclitaxel sensitivity in p53-deficient cells correlated this finding with increased G2/M arrest, we did not observe any significant correlation between paclitaxel-induced cell kill and the degree of mitotic arrest. Paclitaxel 48-58 P53 Homo sapiens 74-77 10393722-14 1999 IMPLICATIONS: 4-HPR may form the basis for a novel, p53-independent chemotherapy that operates through increased intracellular levels of ceramide and that retains cytotoxicity under reduced oxygen conditions. Oxygen 190-196 P53 Homo sapiens 52-55 10391892-2 1999 Accumulation of p53 and induction of apoptosis in RAW 264.7 macrophages in response to nitric oxide are well established. Nitric Oxide 87-99 P53 Homo sapiens 16-19 10391892-3 1999 However, the molecular mechanisms involved in nitric oxide-induced p53 accumulation are unknown. Nitric Oxide 46-58 P53 Homo sapiens 67-70 10391892-6 1999 Moreover, chemically diverse nitric oxide donors interfere with proteasome-mediated degradation of polyubiquitinated p53 in vitro. Nitric Oxide 29-41 P53 Homo sapiens 117-120 10391892-7 1999 These data imply that nitric oxide-induced apoptosis and accumulation of p53 are, at least in part, mediated by inhibition of the proteasome.

Serine 26-32 P53 Homo sapiens 144-147 10435622-5 1999 Here, we report the identification of a novel DNA-activated protein kinase that phosphorylates p53 on serine-15. Serine 102-108 P53 Homo sapiens 95-98 10435622-7 1999 Immunoprecipitation studies of recombinant ATR reveal that catalytic activity of this polypeptide is required for DNA-stimulated phosphorylation of p53 on serine-15.

Nitric Oxide 0-12 P53 Homo sapiens 115-118 10397271-2 1999 Recently, it was suggested that nitric oxide is involved in p53-dependent response to many kinds of stress, such as heat shock and changes in cellular metabolism.

Cisplatin 24-33 P53 Homo sapiens 13-16 10397271-7 1999 In addition, the accumulation of hsp72 and p53 in the wtp53 cells was induced by the administration of an nitric oxide-generating agent, S-nitroso-N-acetylpenicillamine, to the medium. Nitric Oxide 106-118 P53 Homo sapiens 43-46 10437915-1 1999 We have previously shown that p53 mutations are associated with cisplatin resistance in ovarian carcinoma IGROV-1/Pt 1 cells. Cisplatin 64-73 P53 Homo sapiens 30-33 10397271-9 1999 Our finding of the accumulation of hsp72 and p53 in nitric oxide-recipient cells cocultivated with heated nitric oxide-donor cells provides the first evidence for an intercellular signal transduction pathway via nitric oxide as intermediate without cell-to-cell interactions such as gap junctions. Nitric Oxide 52-64 P53 Homo sapiens 45-48 10437915-10 1999 This is the first observation that indicates that a subpopulation of p53 mutant cells can occasionally be selected by cisplatin treatment. Cisplatin 118-127 P53 Homo sapiens 69-72 10483067-2 1999 MATERIALS AND METHODS: The expression of p53 and MDM2 proteins was determined immunohistochemically in 51 formalin-fixed, paraffin embedded specimens of odontogenic cysts and tumours.

Fluorouracil 72-86 P53 Homo sapiens 145-148 10377423-3 1999 p53 mutations were either detected by using both techniques or, if only detected by one technique, were confirmed by using mutation-specific oligonucleotide hybridization. Oligonucleotides 141-156 P53 Homo sapiens 0-3 10383145-7 1999 Mitogen activation further suppressed cisplatin-induced p53 expression, and the inhibition was mainly dependent on the Ca2+ pathway. Cisplatin 38-47 P53 Homo sapiens 56-59 10383157-5 1999 In addition, Hsp90 family chaperone-associated proteins, such as p185erbB2, Raf-1, cyclin-dependent kinase 4, and mutant p53, were depleted by KF25706 at a dose comparable to that required for antiproliferative activity.

Tretinoin 113-115 P53 Homo sapiens 49-52 10364268-4 1999 Upon treatment with RA (1-10 microM) for 4 days, the human NB cells, SH-SY5Y, developed resistance selectively to p53-dependent apoptotic stimuli including gamma-irradiation, etoposide, and 1-(5-isoquinolinyl sulfonyl)-2-methylpiperazine (H-7). Tretinoin 20-22 P53 Homo sapiens 114-117 10364268-5 1999 Interestingly, RA affected the ability of H-7 to induce nuclear accumulation of the p53 protein without altering its effect on elevating the steady-state level of p53, suggesting that drug-induced up-regulation and nuclear accumulation of the wild-type p53 protein are separable processes. Tretinoin 15-17 P53 Homo sapiens 84-87 10364268-6 1999 The modulation of nuclear import of p53 protein by RA may thus represent a potential mechanism by which certain tumor cells with the wild-type p53 gene develop resistance to chemotherapeutic agents. Tretinoin 51-53 P53 Homo sapiens 36-39 10364268-6 1999 The modulation of nuclear import of p53 protein by RA may thus represent a potential mechanism by which certain tumor cells with the wild-type p53 gene develop resistance to chemotherapeutic agents.

Hydrogen Peroxide 28-45 P53 Homo sapiens 70-73 10403664-5 1999 At non-lethal doses, both H2O2 and MMS induced high level of p53 protein accumulation. Hydrogen Peroxide 26-30 P53 Homo sapiens 61-64 10403664-6 1999 Nevertheless, while the amount of p53 protein increased with the dose of MMS and the occurrence of apoptotic cell death events, H2O2 doses that induce cell apoptosis attenuated the p53 protein accumulation level. Hydrogen Peroxide 128-132 P53 Homo sapiens 181-184 12548778-4 1999 In RA-sensitive cell lines, ATRA-induced G0/G1 arrest is associated with down regulaton of c-myc and hyperphosphorylated Rb expression, and up regulation of p21WAF1/CIP1 and p53 expression.

Doxorubicin 32-35 P53 Homo sapiens 217-220 10223459-11 1999 CONCLUSIONS: The present study indicates that clotrimazole inhibits cell proliferation accompanied by morphological changes toward differentiation of glioblastoma cells and that this drug synergistically enhances the antitumor effect of cisplatin by inducing wild-type p53-mediated apoptosis.

Serine 105-111 P53 Homo sapiens 78-81 10212189-8 1999 Incubation of active p38 kinase with p53 protein caused the phosphorylation of p53 protein at serine 389 in vitro, while no phosphorylation of p53 at serine 389 was observed when p53 was incubated with activated JNK2 or ERK2. Serine 94-100 P53 Homo sapiens 79-82 10212189-4 1999 Here, we report that the UV-induced phosphorylation of p53 at serine 389 is mediated by p38 kinase. Serine 62-68 P53 Homo sapiens 55-58 10212189-10 1999 These results strongly suggest that the p38 kinase is at least one of the most important mediators of p53 phosphorylation at serine 389 induced by UVC radiation. Serine 125-131 P53 Homo sapiens 102-105 10212189-5 1999 UVC-induced phosphorylation of p53 at serine 389 was markedly impaired by either pretreatment of cells with p38 kinase inhibitor, SB202190, or stable expression of a dominant negative mutant of p38 kinase.

Serine 145-151 P53 Homo sapiens 138-141 10348347-6 1999 The cooperative nature of transcriptional activation by these factors was documented by repression of c-fos or NF-kappaB1 translation: Pretreatment of the cells with a c-fos or p50(NF-kappaB1) antisense oligonucleotide suppresses transcription from the human p53 promoter completely. Oligonucleotides 203-218 P53 Homo sapiens 259-262 10348347-7 1999 In addition, we show that (a) the level of endogenous p53 mRNA and (b) transcription from the strictly p53-dependent human mdm2 promoter are reduced in the presence of c-fos, c-jun, p50(NF-kappaB1), p65RelA or c-myc antisense oligonucleotides, underscoring the importance of these transcription factors for the expression of functional p53. Oligonucleotides 226-242 P53 Homo sapiens 54-57 10348347-7 1999 In addition, we show that (a) the level of endogenous p53 mRNA and (b) transcription from the strictly p53-dependent human mdm2 promoter are reduced in the presence of c-fos, c-jun, p50(NF-kappaB1), p65RelA or c-myc antisense oligonucleotides, underscoring the importance of these transcription factors for the expression of functional p53. Oligonucleotides 226-242 P53 Homo sapiens 103-106 10348347-7 1999 In addition, we show that (a) the level of endogenous p53 mRNA and (b) transcription from the strictly p53-dependent human mdm2 promoter are reduced in the presence of c-fos, c-jun, p50(NF-kappaB1), p65RelA or c-myc antisense oligonucleotides, underscoring the importance of these transcription factors for the expression of functional p53. Oligonucleotides 226-242 P53 Homo sapiens 103-106 10094816-3 1999 This RA-induced apoptosis was accompanied by p53-independent up-regulation of endogenous p21(CIPI/Waf1) and Bax proteins, as well as activation of p34(cdc2) kinase, and increase of Rb2 protein level and phosphorylation pattern. Tretinoin 5-7 P53 Homo sapiens 45-48 10187847-4 1999 We have confirmed a calcium-dependent interaction of the S100B with a synthetic peptide corresponding to the C-terminal region of p53 (residues 319-393 in human p53) using plasmon resonance experiments on a BIAcore system. Calcium 20-27 P53 Homo sapiens 130-133 10187847-4 1999 We have confirmed a calcium-dependent interaction of the S100B with a synthetic peptide corresponding to the C-terminal region of p53 (residues 319-393 in human p53) using plasmon resonance experiments on a BIAcore system. Calcium 20-27 P53 Homo sapiens 161-164 10327055-0 1999 Wild-type p53 protein shows calcium-dependent binding to F-actin.

Calcium 43-50 P53 Homo sapiens 57-60 10327055-9 1999 Thus, part of the regulatory machinery in normal cell cycling may involve p53-actin interactions regulated by calcium fluxes and the dynamic turnover of F-actin. Calcium 110-117 P53 Homo sapiens 74-77 10327056-3 1999 In the present study, we analysed the mechanisms by which CD437 induces apoptosis in two human NSCLC cell lines: H460 with wild-type p53 and H1792 with mutant p53. CD 437 58-63 P53 Homo sapiens 133-136 10327056-3 1999 In the present study, we analysed the mechanisms by which CD437 induces apoptosis in two human NSCLC cell lines: H460 with wild-type p53 and H1792 with mutant p53. CD 437 58-63 P53 Homo sapiens 159-162 10327056-8 1999 These results suggest that CD437-induced apoptosis is more extensive in NSCLC cells that express wild-type p53, possibly due to the involvement of the p53 regulated genes Killer/DR5, and Bax although CD437 can also induce apoptosis by means of a p53-independent mechanism. CD 437 27-32 P53 Homo sapiens 107-110 10327056-8 1999 These results suggest that CD437-induced apoptosis is more extensive in NSCLC cells that express wild-type p53, possibly due to the involvement of the p53 regulated genes Killer/DR5, and Bax although CD437 can also induce apoptosis by means of a p53-independent mechanism.

Serine 133-139 P53 Homo sapiens 100-103 10082548-8 1999 These results indicate the significance of serine 15 phosphorylation for p53 stabilization after DNA double-strand breaks and an absolute requirement for ATM in this phosphorylation process.

Paclitaxel 75-85 P53 Homo sapiens 8-11 10210535-8 1999 Recent evidence suggests that paclitaxel is unique in its ability to activate apoptosis in tumor cells with p53 mutations in vitro and in vivo. Paclitaxel 30-40 P53 Homo sapiens 108-111 10210536-12 1999 On a molecular level, taxanes activate a number of genes, but it appears that their effects are mainly p53-independent and primarily involve phosphorylation of the Bcl-2 gene. Taxoids 22-29 P53 Homo sapiens 103-106 10210540-5 1999 This finding suggested that paclitaxel/RT was a rational treatment approach for other malignancies that frequently harbor p53 mutations, such as upper gastrointestinal malignancies. Paclitaxel 28-38 P53 Homo sapiens 122-125 10037682-5 1999 Exposure of cerebellar granule cells to glutamate induces a rapid increase in p53 and Bax mRNA and protein levels with no apparent effect on Bcl-2 expression.

S-Nitrosoglutathione 89-93 P53 Homo sapiens 134-137 10029520-9 1999 However, with higher GSNO concentrations apoptotic transducing pathways, including p53 accumulation, were JNK1/2 unrelated.

Resveratrol 0-11 P53 Homo sapiens 117-120 10069459-4 1999 Resveratrol suppresses tumor promoter-induced cell transformation and markedly induces apoptosis, transactivation of p53 activity and expression of p53 protein in the same cell line and at the same dosage. Resveratrol 0-11 P53 Homo sapiens 148-151 10069459-5 1999 Also, resveratrol-induced apoptosis occurs only in cells expressing wild-type p53 (p53+/+), but not in p53-deficient (p53-/-) cells, while there is no difference in apoptosis induction between normal lymphoblasts and sphingomyelinase-deficient cell lines. Resveratrol 6-17 P53 Homo sapiens 78-81 10069459-5 1999 Also, resveratrol-induced apoptosis occurs only in cells expressing wild-type p53 (p53+/+), but not in p53-deficient (p53-/-) cells, while there is no difference in apoptosis induction between normal lymphoblasts and sphingomyelinase-deficient cell lines.

Resveratrol 6-17 P53 Homo sapiens 83-86 10069459-6 1999 These results demonstrate for the first time that resveratrol induces apoptosis through activation of p53 activity, suggesting that its anti-tumor activity may occur through the induction of apoptosis. Resveratrol 50-61 P53 Homo sapiens 102-105 9882333-6 1999 The p53 gene of the parental PGE cells was found to be overexpressed, perhaps thereby conferring the basal potential for long-term survival in vitro. phenylglycidyl ether 29-32 P53 Homo sapiens 4-7 10022646-7 1999 Folic acid supplementation had a small, significant protective effect for p53 mutations (RR 0.97, CI 0.94-1.00). Folic Acid 0-10 P53 Homo sapiens 74-77 10022646-8 1999 CONCLUSION: p53 Mutations 1) are associated with, and likely precede, dysplasia and cancer, 2) are associated with cancer-related mortality, and 3) may possibly be prevented by folic acid supplementation. Folic Acid 177-187 P53 Homo sapiens 12-15 10023783-2 1999 Most recently, p53 protein containing an arginine residue in codon 72 was shown to be more effectively degraded by the E6 oncoprotein of human papillomavirus (HPV) than the corresponding proline isoform in cervical carcinoma cells. Arginine 41-49 P53 Homo sapiens 15-18 9989808-3 1999 Here we report on the correlation between inhibition of mRNA synthesis and the induction of p53, p21WAF1 and apoptosis in diploid human fibroblasts treated with either UV light, cisplatin or the RNA synthesis inhibitors actinomycin D, DRB, H7 and alpha-amanitin. Cisplatin 178-187 P53 Homo sapiens 92-95 9891044-1 1999 The wild-type p53 protein exhibits a common polymorphism at amino acid 72, resulting in either a proline residue (p53Pro) or an arginine residue (p53Arg) at this position.

Oligonucleotides 162-177 P53 Homo sapiens 13-16 9927633-3 1999 PKCalpha antisense oligonucleotide treatment was accompanied by reduction in PKCalpha levels and the induction of wild-type p53 and insulin-like growth factor-binding protein-3 (IGFBP3) 24-72 h after treatment, a period that coincided with the appearance of apoptotic cell death as detected by DNA fragmentation. Oligonucleotides 19-34 P53 Homo sapiens 124-127 9931282-5 1999 Cisplatin caused an 11-fold increase of recombination frequency in yeast and induced transcriptional activation of the DNA damage-associated promoters such as the minimum promoter containing p53 response elements and the GADD45 promoter in addition to activating the promoters for c-fos, heat shock protein 70, metallothionine IIa, and the minimum promoter containing nuclear factor kappa(kappa)B response elements. Cisplatin 0-9 P53 Homo sapiens 191-194 10190571-10 1999 Moreover, the p53 protein accumulates early in glioma cells as a result of Pt(IV)-bis (monoglutarate) treatment. bis (monoglutarate) 82-101 P53 Homo sapiens 14-17 10190571-11 1999 These data indicate that the Pt(IV)-bis (monoglutarate) complex induces apoptosis in glioma cells through a p53-dependent pathway. bis (monoglutarate) 36-55 P53 Homo sapiens 108-111 9989825-9 1999 This detrimental effect of NF-kappaB mediating hydrogen peroxide-induced cell death presumably relies on the induced expression of death effector genes such as p53, which was NF-kappaB-dependently upregulated in the presence of H2O2. Hydrogen Peroxide 47-64 P53 Homo sapiens 160-163 9989825-9 1999 This detrimental effect of NF-kappaB mediating hydrogen peroxide-induced cell death presumably relies on the induced expression of death effector genes such as p53, which was NF-kappaB-dependently upregulated in the presence of H2O2. Hydrogen Peroxide 228-232 P53 Homo sapiens 160-163 9891054-5 1999 In this study, we demonstrate that PCAF also acetylates p53 in vitro at a lysine residue distinct from that acetylated by p300 and thereby increases p53"s ability to bind to its cognate DNA site. Lysine 74-80 P53 Homo sapiens 56-59 9891054-5 1999 In this study, we demonstrate that PCAF also acetylates p53 in vitro at a lysine residue distinct from that acetylated by p300 and thereby increases p53"s ability to bind to its cognate DNA site.

Hydrogen Peroxide 0-17 P53 Homo sapiens 48-51 9890630-5 1999 After treatment with H2O2, p53 protein was highly expressed and protein levels of Bak, p21WAF1/CIP1 and GADD45 were also enhanced. Hydrogen Peroxide 21-25 P53 Homo sapiens 27-30 9890630-8 1999 In addition, p53-deficient astrocytes were more resistant to H2O2-induced apoptosis than wild-type and heterozygous astrocytes. Hydrogen Peroxide 61-65 P53 Homo sapiens 13-16 9925639-5 1999 ATR phosphorylated p53 at Ser-15 and Ser-37 in vitro, suggesting that p53 is a target for phosphorylation by ATR in DNA-damaged cells.

Tritium 13-15 P53 Homo sapiens 75-78 10226587-7 1999 We also propose that apoptosis induced by G-Rs3 is related to the elevations of p53 and p21WAF1 in the cells. g-rs3 42-47 P53 Homo sapiens 80-83 9927204-7 1999 In contrast, p53His175 and p53His273 exerted very similar effects on the cellular response to cisplatin; both conferred increased resistance to low concentrations of the drug (2.5 microg/ml), but did not protect at all against high concentrations (10 microg/ml). Cisplatin 94-103 P53 Homo sapiens 13-16 9926927-7 1999 Our results suggest that the PA26 gene is a novel p53 target gene with properties common to the GADD family of growth arrest and DNA damage-inducible stress-response genes, and, thus, a potential novel regulator of cellular growth. gadd 96-100 P53 Homo sapiens 50-53 10025726-9 1999 In addition, growth in normal calcium medium lowered the UVB-induced stimulation of the p53 protein and altered the normal subcellular localization pattern of p53. Calcium 30-37 P53 Homo sapiens 88-91 10025726-9 1999 In addition, growth in normal calcium medium lowered the UVB-induced stimulation of the p53 protein and altered the normal subcellular localization pattern of p53.

Doxorubicin 41-52 P53 Homo sapiens 9-12 10412949-9 1999 RESULTS: p53 Ad combined with cisplatin, doxorubicin, 5-fluorouracil, methotrexate, or etoposide inhibited cell proliferation more effectively than chemotherapy alone in SCC-9 head and neck, SCC-15 head and neck, SCC-25 head and neck, SK-OV-3 ovarian, DU-145 prostate, MDA-MB-468 breast, and MDA-MB-231 breast tumor cells. Fluorouracil 54-68 P53 Homo sapiens 9-12 10453723-6 1999 Interestingly, wild-type p53val135 abrogated the taxol-imposed G2/M arrest in both cell lines. Paclitaxel 49-54 P53 Homo sapiens 25-28 9950218-6 1999 Increased expression of p53 protein is observed in ATRA-treated HMECs at 72 h; however, initiation of G1-S-phase arrest starts at 24 h, suggesting that this observed induction of p53 is a secondary event. Tretinoin 51-55 P53 Homo sapiens 24-27 10690631-3 1999 The positive clones selected by ELISA were found to exhibit strong staining of nuclear p53 in both fresh and archival paraffin embedded breast tumour tissue sections.

Cisplatin 149-158 P53 Homo sapiens 73-76 9840938-4 1998 To learn if transcriptional activation of downstream genes by p53 plays a role in this putative checkpoint, three cell lines were exposed to nocodazole. Nocodazole 141-151 P53 Homo sapiens 62-65 9840938-7 1998 Incubation with nocodazole of cells containing wild-type p53 results in accumulation of both 2N and 4N populations of cells.

NAD 147-151 P53 Homo sapiens 9-12 9769393-6 1998 On the other hand, an A to G substitution at codon 170 in exon 5 of p53 gene resulting in glutamic acid (ACG) to glycine (GCG) was detected in the DNA of her tongue cancer. Glutamic Acid 90-103 P53 Homo sapiens 68-71 9811465-0 1998 Human lymphoblastoid cell lines expressing mutant p53 exhibit decreased sensitivity to cisplatin-induced cytotoxicity. Cisplatin 87-96 P53 Homo sapiens 50-53 9811465-3 1998 We found that compared to the parental cell line, cells overexpressing mutant p53 (either 246val or 135ser) exhibited decreased apoptosis in response to gamma-radiation or cisplatin as measured by: propidium iodide (PI) staining of the cellular DNA (cell cycle analysis) and decrease in PARP (poly ADP-ribose polymerase) cleavage as detected by Western blotting. Cisplatin 172-181 P53 Homo sapiens 78-81 9811465-4 1998 Interestingly the cells expressing mutant p53(135ser) protein were less resistant to cisplatin-induced apoptosis than the p53(246val)-bearing cell line. Cisplatin 85-94 P53 Homo sapiens 42-45 9811465-5 1998 A significant decrease in the G1/S arrest assayed by bromodeoxyuridine and PI staining (cell cycle/proliferation assay) was also observed in response to irradiation and cisplatin in cell lines expressing either of the mutant p53 constructs. Cisplatin 169-178 P53 Homo sapiens 225-228 9811465-6 1998 A lower basal level and reduced magnitude of protein induction of the cell cycle inhibitor p21/Waf1 was seen both after cisplatin and gamma-radiation treatment in the mutant p53 expressing lymphoblastoid variant when compared to the wild type p53 parental cell line but induction of the p53 regulator MDM2 was comparable in both. Cisplatin 120-129 P53 Homo sapiens 174-177 9811465-8 1998 Unexpectedly, following cisplatin treatment we observed an increase in mutant and wild type p53 RNA steady state levels in addition to increased levels of p53 protein. Cisplatin 24-33 P53 Homo sapiens 92-95 9811465-8 1998 Unexpectedly, following cisplatin treatment we observed an increase in mutant and wild type p53 RNA steady state levels in addition to increased levels of p53 protein. Cisplatin 24-33 P53 Homo sapiens 155-158 9811465-9 1998 These results suggest that irradiation or cisplatin treatment may not only stabilize wild type p53 protein but also may increase the steady state p53 RNA levels. Cisplatin 42-51 P53 Homo sapiens 95-98 9811465-9 1998 These results suggest that irradiation or cisplatin treatment may not only stabilize wild type p53 protein but also may increase the steady state p53 RNA levels. Cisplatin 42-51 P53 Homo sapiens 146-149 9811465-10 1998 Finally these results indicate that both irradiation and cisplatin should be used with caution in the treatment of lymphoid tumors bearing mutations of p53.

Tamoxifen 32-41 P53 Homo sapiens 0-3 9891537-10 1998 CONCLUSIONS: In this small study, tamoxifen associated tumors expressed p53 more frequently than non-users, while the opposite was observed with p21WAF1/CIP1. Tamoxifen 34-43 P53 Homo sapiens 72-75 9891537-11 1998 This suggests that p53 mutations might play a role in development of tamoxifen associated tumors.

Fluorouracil 79-93 P53 Homo sapiens 0-3 9930367-12 1998 These findings indicate that 5-FU and gamma-rays induce apoptosis of squamous cell carcinoma cells in p53- and p21-independent manners, in the S and G2/M phases, respectively. Fluorouracil 29-33 P53 Homo sapiens 102-105 9769393-6 1998 On the other hand, an A to G substitution at codon 170 in exon 5 of p53 gene resulting in glutamic acid (ACG) to glycine (GCG) was detected in the DNA of her tongue cancer.

Steroids 67-74 P53 Homo sapiens 5-8 11825490-6 1998 Both p53 mutation protein and p53 gene mutations were prevalent in steroid and progesterone receptors negative tumors (P < 0.05). Steroids 67-74 P53 Homo sapiens 30-33 9804172-8 1998 These results suggest that the G1 phase arrest by flavone is due to p53-independent transcriptional induction of the p21/WAF1 gene and the subsequent dephosphorylation of RB protein. flavone 50-57 P53 Homo sapiens 68-71 9774464-5 1998 In this way, profound effects of protein kinase A were identified and corroborated in vivo by the protection conferred by cAMP against diverse triggers of p53-dependent apoptosis. Cyclic AMP 122-126 P53 Homo sapiens 155-158 9788435-4 1998 Whereas p21waf1 overexpression conferred increased resistance to killing by either drug, p53 overexpression enhanced the cytotoxic effect of cisplatin but protected against etoposide cytotoxicity.

Fluorouracil 99-103 P53 Homo sapiens 47-50 9792140-6 1998 Using five human colon cancer cell lines, we found that equitoxic (IC50) doses of 5-FU induced apoptosis in both wild-type p53 and mutant p53 cells. Fluorouracil 82-86 P53 Homo sapiens 123-126 9792140-6 1998 Using five human colon cancer cell lines, we found that equitoxic (IC50) doses of 5-FU induced apoptosis in both wild-type p53 and mutant p53 cells.

Alcohols 149-156 P53 Homo sapiens 105-108 9801791-4 1998 The replacement of Trp53 by alanine resulted in a complete loss of the haemagglutinating activity, suggesting that the tryptophan residue in the heptapeptide sequence is essential for carbohydrate binding. Tryptophan 119-129 P53 Homo sapiens 19-24 9766444-6 1998 The differentiation response to transfected p53 with or without INF-gamma was inhibited by cyclic adenosine monophosphate (cAMP)-inducing agents (dibutyryl cyclic adenosine 3":5"-monophosphate, forskolin, and 3-isobutyl-1-methylxanthine) in a dose-dependent manner. Cyclic AMP 91-121 P53 Homo sapiens 44-47 9796984-4 1998 The inhibition of cell growth in FUdR-treated cells by PB was more sustained in U4 than U9 cells and was associated with an increased and sustained expression of p21waf1 protein, secretion of transforming growth factor beta1, mediators of p53-dependent or -independent G1 cell cycle arrest, and an increase in the alkaline phosphatase activity as well, considered a marker of differentiation in colon carcinoma cells.

Cisplatin 96-124 P53 Homo sapiens 133-136 9893672-3 1998 It was found that the sensitivity of the cells to CDDP correlated with the amount of infectious units of virus per cell of AxCAp53 which correlated with p53 protein expression. Cisplatin 50-54 P53 Homo sapiens 127-130 9766444-6 1998 The differentiation response to transfected p53 with or without INF-gamma was inhibited by cyclic adenosine monophosphate (cAMP)-inducing agents (dibutyryl cyclic adenosine 3":5"-monophosphate, forskolin, and 3-isobutyl-1-methylxanthine) in a dose-dependent manner.

Tyrosine 99-107 P53 Homo sapiens 81-84 9764849-0 1998 Curcumin induces a p53-dependent apoptosis in human basal cell carcinoma cells. Curcumin 0-8 P53 Homo sapiens 19-22 9764849-3 1998 In our study, consistent with the occurrence of DNA fragmentation, nuclear p53 protein initially increased at 12 h and peaked at 48 h after curcumin treatment.

Curcumin 113-121 P53 Homo sapiens 75-78 9764849-4 1998 Prior treatment of cells with cycloheximide or actinomycin D abolished the p53 increase and apoptosis induced by curcumin, suggesting that either de novo p53 protein synthesis or some proteins synthesis for stabilization of p53 is required for apoptosis. Curcumin 113-121 P53 Homo sapiens 154-157 9764849-4 1998 Prior treatment of cells with cycloheximide or actinomycin D abolished the p53 increase and apoptosis induced by curcumin, suggesting that either de novo p53 protein synthesis or some proteins synthesis for stabilization of p53 is required for apoptosis.

Curcumin 138-146 P53 Homo sapiens 160-163 9764849-10 1998 Finally, treatment of cells with p53 antisense oligonucleotide could effectively prevent curcumin-induced intracellular p53 protein increase and apoptosis, but sense p53 oligonucleotide could not.

Curcumin 89-97 P53 Homo sapiens 120-123 9764849-10 1998 Finally, treatment of cells with p53 antisense oligonucleotide could effectively prevent curcumin-induced intracellular p53 protein increase and apoptosis, but sense p53 oligonucleotide could not. Oligonucleotides 170-185 P53 Homo sapiens 33-36 9764849-11 1998 Thus, our data suggest that the p53-associated signaling pathway is critically involved in curcumin-mediated apoptotic cell death. Curcumin 91-99 P53 Homo sapiens 32-35 9714063-11 1998 Our results suggest an overall association between wild type P53 and radiation and platinum drug sensitivity in these ovarian cancer cell lines. Platinum 83-91 P53 Homo sapiens 61-64 11245004-1 1998 OBJECTIVE: To establish a tetracycline-regulated expression model and to determine and verify whether a specific point mutant type p53 minigene, containing an Arg-->Leu substitution at amino acid 172, possesses a suppressing effect on human lung cancer. Arginine 159-162 P53 Homo sapiens 131-134 9794234-1 1998 Dexamethasone (DEX)-mediated inhibition of drug-induced, but not CD95 ligand-induced, apoptosis in malignant glioma cells correlates with wild-type p53 status. Dexamethasone 0-13 P53 Homo sapiens 148-151 9794234-1 1998 Dexamethasone (DEX)-mediated inhibition of drug-induced, but not CD95 ligand-induced, apoptosis in malignant glioma cells correlates with wild-type p53 status. Dexamethasone 15-18 P53 Homo sapiens 148-151 9794234-5 1998 p53val135-transfected cells retained responsiveness to DEX at restrictive temperature, suggesting that p53 activity is not required for cytoprotection. Dexamethasone 55-58 P53 Homo sapiens 0-3 9794234-6 1998 Forced expression of wild-type p53val135 abrogated the protective effect of DEX, suggesting redundant cytoprotective effects of DEX and p53.

Dexamethasone 128-131 P53 Homo sapiens 31-34 9794234-7 1998 Indeed, DEX induced moderate accumulation of p21WAF1/CIP1 in U87MG, LN-229 and p53 mutant LN-18 cells, but not in p53 mutant LN-308 or T98G cells. Dexamethasone 8-11 P53 Homo sapiens 79-82 9794234-8 1998 LN-18 is also the p53 mutant cell line with the best cytoprotective response to DEX. Dexamethasone 80-83 P53 Homo sapiens 18-21 9794234-10 1998 Wild-type p53 was not required for this DEX effect since DEX induced p21WAF1/CIP1 accumulation in p53val135-transfected LN-229 cells, too. Dexamethasone 57-60 P53 Homo sapiens 98-101 9794234-14 1998 The present study links DEX-mediated protection from cancer chemotherapy to a p53-independent pathway of regulating p21WAF1/CIP1 expression in glioma cells but this effect appears to cell type-specific. Dexamethasone 24-27 P53 Homo sapiens 78-81 9744860-4 1998 p300 acetylates Lys-382 in the carboxy-terminal region of p53, whereas PCAF acetylates Lys-320 in the nuclear localization signal. Lysine 16-19 P53 Homo sapiens 58-61 9744860-6 1998 Using a polyclonal antisera specific for p53 that is phosphorylated or acetylated at specific residues, we show that Lys-382 of human p53 becomes acetylated and Ser-33 and Ser-37 become phosphorylated in vivo after exposing cells to UV light or ionizing radiation.

Serine 73-76 P53 Homo sapiens 25-28 9744860-7 1998 In vitro, amino-terminal p53 peptides phosphorylated at Ser-33 and/or at Ser-37 differentially inhibited p53 acetylation by each HAT. Serine 73-76 P53 Homo sapiens 105-108 9742979-1 1998 BACKGROUND: A polymorphism at codon 72 of the human tumour-suppressor gene, p53, results in translation to either arginine or proline. Arginine 114-122 P53 Homo sapiens 76-79 9733514-5 1998 ATM phosphorylated p53 in vitro on a single residue, serine-15, which is phosphorylated in vivo in response to DNA damage. Serine 53-59 P53 Homo sapiens 19-22 9733515-1 1998 The p53 tumor suppressor protein is activated and phosphorylated on serine-15 in response to various DNA damaging agents. Serine 68-74 P53 Homo sapiens 4-7 9733515-3 1998 Immunoprecipitated ATM had intrinsic protein kinase activity and phosphorylated p53 on serine-15 in a manganese-dependent manner. Serine 87-93 P53 Homo sapiens 80-83 9733515-5 1998 These observations, along with the fact that phosphorylation of p53 on serine-15 in response to ionizing radiation is reduced in ataxia telangiectasia cells, suggest that ATM is a protein kinase that phosphorylates p53 in vivo. Serine 71-77 P53 Homo sapiens 64-67 9742979-8 1998 INTERPRETATION: In the population studied, individuals homozygous for the arginine variant of codon 72 of the p53 gene were not at increased risk of cervical cancer. Arginine 74-82 P53 Homo sapiens 110-113 9731490-7 1998 Given the role of p53 in the response of cells to irradiation, we evaluated whether p53 function affects the observed radiation-induced resistance to cisplatin. Cisplatin 150-159 P53 Homo sapiens 84-87 14646487-6 1998 One model indicates that p53 induces redox-related genes that generate reactive oxygen species and promote the oxidative degradation of mitochondrial components. Reactive Oxygen Species 71-94 P53 Homo sapiens 25-28 9743293-8 1998 Thus, although p53-dependent apoptosis is induced by camptothecin, topotecan and SN-38 in this human ovarian carcinoma cell line, these drugs induce p53-independent death, as measured by clonogenic assay. Irinotecan 81-86 P53 Homo sapiens 15-18 9731490-8 1998 By examining isogenic cell lines differing only in p53 function, we demonstrated that radiation conferred resistance to cisplatin independently of p53. Cisplatin 120-129 P53 Homo sapiens 51-54 10921032-2 1998 METHODS: The expression of p53 protein and PCNA was examined by means of SP immunohistochemical technique in 32 cases of peripheral lung cancer proved by pathology; the relationship between the results and preoperative CT features was analyzed retrospectively. TFF2 protein, human 73-75 P53 Homo sapiens 27-30 9713990-6 1998 Under conditions of cellular stress (ultraviolet irradiation or exposure to bleomycin or cisplatin), expression of TP53TG1 was induced in a wild-type TP53-dependent manner, indicating that this gene is likely to play an important role in the signaling pathway of TP53 and may function in response to cellular damage. Cisplatin 89-98 P53 Homo sapiens 115-119 9713990-6 1998 Under conditions of cellular stress (ultraviolet irradiation or exposure to bleomycin or cisplatin), expression of TP53TG1 was induced in a wild-type TP53-dependent manner, indicating that this gene is likely to play an important role in the signaling pathway of TP53 and may function in response to cellular damage. Cisplatin 89-98 P53 Homo sapiens 150-154 9712657-5 1998 The activation of alpha-Bgt-AChRs by nicotine results in the induction of the tumor suppressor protein p53 and the cdk inhibitor p21. Nicotine 37-45 P53 Homo sapiens 103-106 9796399-8 1998 Analysis of the p53 gene by the polymerase chain reaction-single strand conformation polymorphism method showed one base transposition, from TAT to TGT (Tyr to Cys), at codon 220 of exon 6. Tyrosine 153-156 P53 Homo sapiens 16-19 9796399-8 1998 Analysis of the p53 gene by the polymerase chain reaction-single strand conformation polymorphism method showed one base transposition, from TAT to TGT (Tyr to Cys), at codon 220 of exon 6. Cysteine 160-163 P53 Homo sapiens 16-19 9771923-12 1998 However, the basal level of p53 was higher in resistant clones and addition of 2- or 4-hydroxyestrone increased p53 to levels equivalent to those observed following UVB irradiation. 2- or 4-hydroxyestrone 79-101 P53 Homo sapiens 112-115 9790785-8 1998 Exons 2 through 11 of the p53 gene were analyzed by direct DNA sequencing, revealing a homozygous mutation at codon 281 in exon 8, GAC to CAC (Asp-->His). Histidine 152-155 P53 Homo sapiens 26-29 9729267-8 1998 Linear regression analysis detected a significant increase in the number of 6-TG-resistant clones in both AHH-1 tk+/- (p53+/-) and L3 (p53+/+). Thioguanine 76-80 P53 Homo sapiens 119-122 9729267-8 1998 Linear regression analysis detected a significant increase in the number of 6-TG-resistant clones in both AHH-1 tk+/- (p53+/-) and L3 (p53+/+).

Tamoxifen 80-89 P53 Homo sapiens 0-3 9747884-4 1998 Using antibodies that can detect serine 392-phosphorylation of p53, we demonstrate that UV radiation can trigger extensive phosphorylation at the CK2 site. Serine 33-39 P53 Homo sapiens 63-66 9747884-6 1998 However, a striking increase in UV-induced serine 392 phosphorylation and p53 transactivation function at higher levels of DRB suggests that a DRB-resistant/stress-activated pathway may target serine 392 in vivo. Dichlororibofuranosylbenzimidazole 123-126 P53 Homo sapiens 74-77 9747884-6 1998 However, a striking increase in UV-induced serine 392 phosphorylation and p53 transactivation function at higher levels of DRB suggests that a DRB-resistant/stress-activated pathway may target serine 392 in vivo. Serine 193-199 P53 Homo sapiens 74-77 9747884-7 1998 These data demonstrate that radiation-induced phosphorylation of p53 can occur in vivo at serine 392 and implicate a CK2-independent signal cascade that can function to modulate serine 392 phosphorylation in cells. Serine 90-96 P53 Homo sapiens 65-68 9747884-7 1998 These data demonstrate that radiation-induced phosphorylation of p53 can occur in vivo at serine 392 and implicate a CK2-independent signal cascade that can function to modulate serine 392 phosphorylation in cells. Serine 178-184 P53 Homo sapiens 65-68 9751262-2 1998 We show that the treatment of either MCF-7 (containing wild-type p53) or MDA-MB-231 cells (containing mutant p53) with tamoxifen resulted in apoptotic nuclear changes and an increase in the pre-G1 apoptotic population. Tamoxifen 119-128 P53 Homo sapiens 65-68 9685342-2 1998 E1A expression caused accumulation of wild type p53 more than 10-fold within 24 h after dexamethasone treatment. Dexamethasone 88-101 P53 Homo sapiens 48-51 9751262-2 1998 We show that the treatment of either MCF-7 (containing wild-type p53) or MDA-MB-231 cells (containing mutant p53) with tamoxifen resulted in apoptotic nuclear changes and an increase in the pre-G1 apoptotic population. Tamoxifen 119-128 P53 Homo sapiens 109-112 9685342-4 1998 p53 accumulated was degraded efficiently in vitro in the S10-0 extract (S10-0) prepared from MA1 cells in an ATP and ubiquitin-dependent manner, but not in S10-24 prepared after treatment with dexamethasone for 24 h. The p53 polyubiquitination activity in S100-0 was calcium-dependent and reduced greatly in S100-24. Adenosine Triphosphate 109-112 P53 Homo sapiens 0-3 9685342-4 1998 p53 accumulated was degraded efficiently in vitro in the S10-0 extract (S10-0) prepared from MA1 cells in an ATP and ubiquitin-dependent manner, but not in S10-24 prepared after treatment with dexamethasone for 24 h. The p53 polyubiquitination activity in S100-0 was calcium-dependent and reduced greatly in S100-24. Dexamethasone 193-206 P53 Homo sapiens 0-3 9773808-0 1998 Mitoguazone induces apoptosis via a p53-independent mechanism. Mitoguazone 0-11 P53 Homo sapiens 36-39 9685342-4 1998 p53 accumulated was degraded efficiently in vitro in the S10-0 extract (S10-0) prepared from MA1 cells in an ATP and ubiquitin-dependent manner, but not in S10-24 prepared after treatment with dexamethasone for 24 h. The p53 polyubiquitination activity in S100-0 was calcium-dependent and reduced greatly in S100-24. Calcium 267-274 P53 Homo sapiens 0-3 9773808-8 1998 The present study demonstrated that mitoguazone induces apoptosis in all the different human cancer cell lines tested in a concentration- and time-dependent way, and triggers a p53-independent programmed cell death in the human breast cancer MCF7 cell line.

Paclitaxel 25-35 P53 Homo sapiens 137-141 9703286-3 1998 The TP53 status has been analysed at the DNA level in tumours from 45 ovarian cancer patients randomized to treatment with paclitaxel and cisplatin or cyclophosphamide and cisplatin. Cisplatin 138-147 P53 Homo sapiens 4-8 9703286-3 1998 The TP53 status has been analysed at the DNA level in tumours from 45 ovarian cancer patients randomized to treatment with paclitaxel and cisplatin or cyclophosphamide and cisplatin. Cisplatin 172-181 P53 Homo sapiens 4-8 9703286-8 1998 When relapse-free survival was estimated for all patients with TP53 alterations in their tumours, a significant better outcome for the paclitaxel/cisplatin group was found compared with the patient group receiving cyclophosphamide and cisplatin therapy (P = 0.002). Paclitaxel 135-145 P53 Homo sapiens 63-67 9694807-2 1998 The ability of E1A to induce p53 and its transcriptional targets is severely compromised in ARF-null cells, which remain resistant to apoptosis following serum depletion or adriamycin treatment. Doxorubicin 173-183 P53 Homo sapiens 29-32 9664116-6 1998 Butyrolactone I inhibited proliferation of all colon carcinoma cell lines at 100 microM and it induced apoptosis in LoVo cell line with induction of p53. butyrolactone I 0-15 P53 Homo sapiens 149-152 9664115-3 1998 Treatment with cisplatin and carboplatin also provoked an increase in the level of p53 and p21, and a lowering in Bcl-2. Cisplatin 15-24 P53 Homo sapiens 83-86 9677415-0 1998 Cooperation of a single lysine mutation and a C-terminal domain in the cytoplasmic sequestration of the p53 protein. Lysine 24-30 P53 Homo sapiens 104-107 9712551-2 1998 MATERIAL AND METHODS: The effect of BBI pre-treatment on p53 protein level and on mRNA levels of downstream genes (ERCC3, Gadd45 and p53) was investigated. Amiodarone 36-39 P53 Homo sapiens 57-60 9712551-4 1998 In non-irradiated cells, pre-incubation with BBI resulted in an increased level of p53 protein. Amiodarone 45-48 P53 Homo sapiens 83-86 9664139-11 1998 Major differences between DEX and MEL were also observed with respect to their effects on the levels of bcl-2 and p53. Dexamethasone 26-29 P53 Homo sapiens 114-117 9677415-6 1998 Mutagenesis analysis demonstrated that a single amino acid mutation of Lys-305 (mt p53) caused cytoplasmic sequestration of the p53 protein in the MCF-7 and RKO cells, whereas the fusion protein was distributed in both the cytoplasm and the nucleus of SAOS-2 cells. Lysine 71-74 P53 Homo sapiens 83-86 9697772-4 1998 We find that hypoxia/hypoglycaemia-regulated genes involved in controlling the cell cycle are either HIF-1alpha-dependent (those encoding the proteins p53, p21, Bcl-2) or HIF-1alpha-independent (p27, GADD153), suggesting that there are at least two different adaptive responses to being deprived of oxygen and nutrients. Oxygen 299-305 P53 Homo sapiens 151-154 9677415-6 1998 Mutagenesis analysis demonstrated that a single amino acid mutation of Lys-305 (mt p53) caused cytoplasmic sequestration of the p53 protein in the MCF-7 and RKO cells, whereas the fusion protein was distributed in both the cytoplasm and the nucleus of SAOS-2 cells. Lysine 71-74 P53 Homo sapiens 128-131 9677415-10 1998 Lys-305 is needed for nuclear import of p53 protein, and amino acid residues 326-355 can sequester mt p53 in the cytoplasm. Lysine 0-3 P53 Homo sapiens 40-43 9677415-10 1998 Lys-305 is needed for nuclear import of p53 protein, and amino acid residues 326-355 can sequester mt p53 in the cytoplasm. Lysine 0-3 P53 Homo sapiens 102-105 9692554-3 1998 Using mimosine, a p21Waf1/Cip1 inducer that bypasses the requirement for transcriptional transactivation by p53, we demonstrated that a G1 cell cycle arrest can prevent apoptosis following UV-irradiation or treatment with an RNA polymerase 11 inhibitor. Mimosine 6-14 P53 Homo sapiens 108-111 9710241-1 1998 We examined the mechanism of DNA damage induced by a mutagenic tyrosine metabolite, homogentisic acid (HGA), using 32P-5"-end-labeled DNA fragments obtained from the human p53 tumor suppressor gene. Homogentisic Acid 84-101 P53 Homo sapiens 172-175 9690520-3 1998 Here we report that exposure of macrophages to lipopolysaccharide/interferon-gamma or lipophilic cAMP analogs such as dibutyryl-cAMP or 8-bromo-cAMP for 15 h attenuated DNA fragmentation and accumulation of the tumor suppressor p53 in response to the chemotherapeutic agents cisplatin and etoposide, compared to cells that received chemotherapeutic agents only. Cyclic AMP 97-101 P53 Homo sapiens 228-231 9690520-8 1998 Incubating macrophages with decoy, but not with control oligonucleotides, reduced cAMP evoked protection and simultaneously restored p53 accumulation in response to chemotherapeutic agents. Cyclic AMP 82-86 P53 Homo sapiens 133-136 9690520-9 1998 Our studies demonstrate that cAMP-initiated gene activation regulates the sensitivity towards DNA damaging agents via inhibition of a p53 dependent pathway. Cyclic AMP 29-33 P53 Homo sapiens 134-137 9651310-6 1998 The cyclic AMP-response element in the PCNA core promoter, besides being crucial for basal transcription, synergizes with p53 to activate transcription. Cyclic AMP 4-14 P53 Homo sapiens 122-125 9668066-0 1998 Pyrrolidine dithiocarbamate prevents p53 activation and promotes p53 cysteine residue oxidation. Cysteine 69-77 P53 Homo sapiens 65-68 9668066-9 1998 We found that PDTC increased p53 cysteine residue oxidation in vivo. Cysteine 33-41 P53 Homo sapiens 29-32 9665463-2 1998 In this study we investigated by immunohistochemistry and Western blotting whether calcium and the phorbol ester 12-O-tetradecanoylphorbol-13-acetate, well characterized differentiation signals, induce p21WAF1 in cultured normal human keratinocytes and whether induction of p21WAF1 in this system depends on protein kinase C activation or functional p53. Calcium 83-90 P53 Homo sapiens 350-353 9713515-5 1998 RESULTS: The introduction of wild-type p53 gene into HT1376 markedly enhanced the sensitivity to cisplatin in vitro. Cisplatin 97-106 P53 Homo sapiens 39-42 9688948-4 1998 We found that three mesothelioma cell lines (1 with wild-type p53) were highly resistant to apoptosis induced by oxidant stimuli (asbestos, H2O2) or nonoxidant stimuli (calcium ionophore) compared with primary cultured mesothelial cells. Hydrogen Peroxide 140-144 P53 Homo sapiens 62-65 9655287-4 1998 Histopathologic/genetic analysis of p53 was performed on formalin fixed, paraffin embedded tissues. Paraffin 73-81 P53 Homo sapiens 36-39 9703910-0 1998 An exogenous cdk inhibitor, butyrolactone-I, induces apoptosis with increased Bax/Bcl-2 ratio in p53-mutated pancreatic cancer cells. butyrolactone I 28-43 P53 Homo sapiens 97-100 9703910-5 1998 In butyrolactone-I-treated PANC-1 cells, expression of p53 protein was unchanged, but Bax expression was slightly upregulated and Bcl-2 expression was predominantly down-regulated. butyrolactone I 3-18 P53 Homo sapiens 55-58 9661907-5 1998 cAMP intracellular levels were higher in thyroid cells transfected with the p53 gene mutated at the 392 site than in the untransfected thyroid cells, but lower in the cells transfected with the other mutated p53 genes. Cyclic AMP 0-4 P53 Homo sapiens 76-79 9649454-1 1998 BACKGROUND & AIMS: We previously discovered anti-p53 antibodies predating a cancer diagnosis in subjects at increased risk for liver, lung, breast, and prostate cancer.

Cyclic AMP 0-4 P53 Homo sapiens 208-211 9661907-7 1998 The results of this study suggest that p53 exerts effects on cAMP transduction pathway in thyroid cells, which are exquisitely sensitive to cAMP. Cyclic AMP 61-65 P53 Homo sapiens 39-42 9661907-7 1998 The results of this study suggest that p53 exerts effects on cAMP transduction pathway in thyroid cells, which are exquisitely sensitive to cAMP. Cyclic AMP 140-144 P53 Homo sapiens 39-42 9703382-7 1998 Serum ionized calcium tended to be higher in p53-positive glands in all histopathological groups; however, the difference was only significant in nodular hyperplasias (P = 0.018). Calcium 14-21 P53 Homo sapiens 45-48 9698467-0 1998 Lisofylline sensitizes p53 mutant human ovarian carcinoma cells to the cytotoxic effects of cis-diamminedichloroplatinum (II). Cisplatin 92-120 P53 Homo sapiens 23-26 9698467-5 1998 Restoration of wild-type p53 phenotype by transfection of SKOV3 cells with a p53 cDNA expression vector showed reversal of sensitization by Lisofylline to CDDP cytotoxicity. Cisplatin 155-159 P53 Homo sapiens 25-28 9698467-5 1998 Restoration of wild-type p53 phenotype by transfection of SKOV3 cells with a p53 cDNA expression vector showed reversal of sensitization by Lisofylline to CDDP cytotoxicity. Cisplatin 155-159 P53 Homo sapiens 77-80 9698467-8 1998 Our results show that the combination of CDDP and Lisofylline preferentially sensitizes p53-defective cancer cells to the cytotoxic effect of CDDP by a yet undetermined mechanism.

Carbon 61-67 P53 Homo sapiens 100-103 9687977-11 1998 CONCLUSION: Accelerated carbon beams can yield higher RBE in gamma-resistant glioblastoma cell lines with p53 mutations. Carbon 24-30 P53 Homo sapiens 106-109 9661637-11 1998 All three cell lines became more sensitive to adriamycin after wt p53 expression, with a 10-fold decrease in IC50 values. Doxorubicin 46-56 P53 Homo sapiens 66-69 9636999-1 1998 We tested the hypothesis that the instability of the trinucleotide CTG at the myotonic dystrophy (DM) locus could be an intrinsic DNA damage recognisable by the p53 cell-cycle checkpoint system. trinucleotide 53-66 P53 Homo sapiens 161-164 9666152-8 1998 Antisense oligonucleotides for p53 significantly increased the number of surviving neurons during hypoxic exposure.

Serine 304-307 P53 Homo sapiens 171-174 9605749-3 1998 A carboxyl-terminal fragment containing the last 92 amino acids of p53 (GST-299-390) was sufficient for binding to topoisomerase I.

Purified wild-type human p53 and point mutants Ser-239, Ser-245, and His-273 were equivalent in their enhancement of human topoisomerase I activity. Histidine 326-329 P53 Homo sapiens 67-70 9605749-3 1998 A carboxyl-terminal fragment containing the last 92 amino acids of p53 (GST-299-390) was sufficient for binding to topoisomerase I. Nanomolar concentrations of either GST-p53 or GST-299-390 enhanced the catalytic activity of purified human topoisomerase I. Purified wild-type human p53 and point mutants Ser-239, Ser-245, and His-273 were equivalent in their enhancement of human topoisomerase I activity. Histidine 326-329 P53 Homo sapiens 171-174 9605749-3 1998 A carboxyl-terminal fragment containing the last 92 amino acids of p53 (GST-299-390) was sufficient for binding to topoisomerase I.

Purified wild-type human p53 and point mutants Ser-239, Ser-245, and His-273 were equivalent in their enhancement of human topoisomerase I activity. Histidine 326-329 P53 Homo sapiens 171-174 9627114-3 1998 Gel shift assays demonstrated that p53 specifically binds to an oligonucleotide derived from the p53 binding site of the p22/PRG1 promoter. Oligonucleotides 64-79 P53 Homo sapiens 97-100 9627114-8 1998 Gamma-irradiation of rat splenocytes or doxorubicin-treatment of Hela cells increased p53 levels followed by transcriptional activation of p22/PRG1 and p21/Waf1 in parallel. Doxorubicin 40-51 P53 Homo sapiens 86-89 9620551-0 1998 Human male germ cell tumor resistance to cisplatin is linked to TP53 gene mutation. Cisplatin 41-50 P53 Homo sapiens 64-68 9607583-9 1998 In this study, we also present data linking specific p53 point mutations to TS expression levels and resistance to 5-FU. Fluorouracil 115-119 P53 Homo sapiens 53-56 9620551-8 1998 The simplest explanation for the resistance of this subset of GCTs that are resistant to cisplatin-based chemotherapy, is the inability of the cells to mount an apoptotic response following exposure due to a functionally inactivating mutation in the TP53 gene. Cisplatin 89-98 P53 Homo sapiens 250-254 9620557-4 1998 Moreover, a HeLa clone stably transfected with a temperature sensitive (ts) 143 Ala p53 mutant exhibited temperature-dependent regulation of H19 expression. Alanine 80-83 P53 Homo sapiens 84-87 9635829-0 1998 Expression of p53, Bcl-2 and Bax in cisplatin-induced apoptosis in testicular germ cell tumour cell lines. Cisplatin 36-45 P53 Homo sapiens 14-17 9635829-5 1998 We next analysed the relationship between p53 status and cisplatin-induced up-regulation of p53, and the susceptibility to cisplatin-induced apoptosis. Cisplatin 57-66 P53 Homo sapiens 42-45 9635829-5 1998 We next analysed the relationship between p53 status and cisplatin-induced up-regulation of p53, and the susceptibility to cisplatin-induced apoptosis. Cisplatin 57-66 P53 Homo sapiens 92-95 9635829-11 1998 The present study suggests that, at least in our panel of TGCT cell lines, hypersensitivity for cisplatin-induced apoptosis might not be necessarily correlated with the presence of wild-type p53 and is probably not associated with Bcl-2 and Bax expression. Cisplatin 96-105 P53 Homo sapiens 191-194 9595036-8 1998 Strong positive nuclear staining of the p53 protein was detected in both normal and tumor paraffin-embedded tissues. Paraffin 90-98 P53 Homo sapiens 40-43 9652752-5 1998 In fact, in A2780 cells, TX (with or without CDDP) treatment markedly increased p53 as well as p21waf1 protein expression. Cisplatin 45-49 P53 Homo sapiens 80-83 9602097-9 1998 Given that both p53 and Myc have been implicated in gene signalling pathways which mediate programmed cell death, our findings which demonstrate that 4-VO produces persistent elevations of p53- and Myc-like immunoreactivities in vulnerable neurons suggest that these proteins may also contribute to delayed neuronal death following an episode of transient forebrain ischemia. 4-vo 150-154 P53 Homo sapiens 16-19 9602097-9 1998 Given that both p53 and Myc have been implicated in gene signalling pathways which mediate programmed cell death, our findings which demonstrate that 4-VO produces persistent elevations of p53- and Myc-like immunoreactivities in vulnerable neurons suggest that these proteins may also contribute to delayed neuronal death following an episode of transient forebrain ischemia. 4-vo 150-154 P53 Homo sapiens 189-192 9607592-3 1998 The sensitization ratio due to the transfected wt p53 varied from about 2-fold for cisplatin to over 50-fold for thymidine. Cisplatin 83-92 P53 Homo sapiens 50-53 9797696-10 1998 There was a statistically significant dose-response effect of platinum-based chemotherapy in patients with p53 negative tumours, which could not be seen in patients with p53 positive tumours (P = 0.01 versus P = 0.553). Platinum 62-70 P53 Homo sapiens 107-110 9628583-0 1998 Induction of p53 without increase in p21WAF1 in betulinic acid-mediated cell death is preferential for human metastatic melanoma. betulinic acid 48-62 P53 Homo sapiens 13-16 9628583-4 1998 Our data suggest that betulinic acid exerts its inhibitory effect partly by increasing p53 without a comparable effect on p21WAF1. betulinic acid 22-36 P53 Homo sapiens 87-90 9797697-4 1998 Immunohistochemical expression of p53 protein was evaluated in formalin-fixed paraffin-embedded sections of CRC liver metastases using the monoclonal antibodies (MAbs) D01 and Pab 1801. Paraffin 78-86 P53 Homo sapiens 34-37 9620358-4 1998 After stimulation with anti-CD3 monoclonal antibody (mAb) OKT3 and phorbol myristate acetate (PMA), T cells from young humans exhibited severalfold increases in p53 protein expression compared with resting T cells. Tetradecanoylphorbol Acetate 67-92 P53 Homo sapiens 161-164 9579543-3 1998 p53 protein immunohistochemistry was performed on 37 paraffin embedded biopsies from 27 patients with CTCL; LCT was present in 15 biopsies. Paraffin 53-61 P53 Homo sapiens 0-3 9620358-4 1998 After stimulation with anti-CD3 monoclonal antibody (mAb) OKT3 and phorbol myristate acetate (PMA), T cells from young humans exhibited severalfold increases in p53 protein expression compared with resting T cells. Tetradecanoylphorbol Acetate 94-97 P53 Homo sapiens 161-164 9610658-7 1998 CONCLUSIONS: Immunohistochemically detected p53 protein status in NSCLC patients may be a promising indicator in determining in vitro chemosensitivity to some anticancer drugs, especially 5-Fu and ADM. Fluorouracil 188-192 P53 Homo sapiens 44-47 9584207-8 1998 These data suggest that apoptosis in A2780 and A2780/cp70 is associated with an increased level of Bak and 21 kDa Bax after drug-induced damage and that functional p53 may be required for this effect after cisplatin but not after paclitaxel. Cisplatin 206-215 P53 Homo sapiens 164-167 9584207-8 1998 These data suggest that apoptosis in A2780 and A2780/cp70 is associated with an increased level of Bak and 21 kDa Bax after drug-induced damage and that functional p53 may be required for this effect after cisplatin but not after paclitaxel. Paclitaxel 230-240 P53 Homo sapiens 164-167 9584207-0 1998 Cisplatin- and paclitaxel-induced apoptosis of ovarian carcinoma cells and the relationship between bax and bak up-regulation and the functional status of p53. Cisplatin 0-9 P53 Homo sapiens 155-158 9584207-0 1998 Cisplatin- and paclitaxel-induced apoptosis of ovarian carcinoma cells and the relationship between bax and bak up-regulation and the functional status of p53. Paclitaxel 15-25 P53 Homo sapiens 155-158 9588214-6 1998 As expected, PD98059 inhibited induction of p53 mRNA and p21WAF1/CIP1 promoter by IGF I. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 13-20 P53 Homo sapiens 44-47 9584207-1 1998 We investigated the roles of p53 and Bcl-2 homologues in the induction of apoptosis by cisplatin and paclitaxel in wild-type p53-expressing human ovarian carcinoma cells and cisplatin-resistant derivatives that have lost p53 function. Cisplatin 87-96 P53 Homo sapiens 29-32 9584207-1 1998 We investigated the roles of p53 and Bcl-2 homologues in the induction of apoptosis by cisplatin and paclitaxel in wild-type p53-expressing human ovarian carcinoma cells and cisplatin-resistant derivatives that have lost p53 function. Paclitaxel 101-111 P53 Homo sapiens 125-128 9584207-1 1998 We investigated the roles of p53 and Bcl-2 homologues in the induction of apoptosis by cisplatin and paclitaxel in wild-type p53-expressing human ovarian carcinoma cells and cisplatin-resistant derivatives that have lost p53 function. Paclitaxel 101-111 P53 Homo sapiens 125-128 9531612-2 1998 We examined the role of the p53 tumor suppressor gene in hematopoietic recovery in vivo after treatment with the cytotoxic drug 5-fluorouracil (5-FU). Fluorouracil 128-142 P53 Homo sapiens 28-31 9619832-11 1998 However, the adriamycin-induced reduction in BRCA1 and BRCA2 mRNA levels was correlated with p53 functional status. Doxorubicin 13-23 P53 Homo sapiens 93-96 9619832-12 1998 MCF-7 cells transfected with a dominant negative mutant p53 (143 val-->ala) required at least tenfold higher doses of adriamycin to down-regulate BRCA1 and BRCA2 mRNAs than did parental MCF-7 cells or control-transfected MCF-7 clones. Doxorubicin 121-131 P53 Homo sapiens 56-59 9619834-8 1998 The p53 gene was found to be wild-type in all cases where mdm2-P2 levels were induced by cisplatin. Cisplatin 89-98 P53 Homo sapiens 4-7 9531612-2 1998 We examined the role of the p53 tumor suppressor gene in hematopoietic recovery in vivo after treatment with the cytotoxic drug 5-fluorouracil (5-FU). Fluorouracil 144-148 P53 Homo sapiens 28-31 9531612-4 1998 Analysis of the repopulation ability and clonogenic activity of hematopoietic stem cells (HSCs) and their lineage-committed descendants showed a greater number of HSCs responsible for reconstitution of lethally irradiated recipients in p53-/- bone marrow cells (BMCs) recovering after 5-FU treatment than in the corresponding p53+/+ BMCs. Fluorouracil 285-289 P53 Homo sapiens 236-239 9531612-7 1998 The pool of HSCs from 5-FU-treated p53-/- BMCs was exhausted more slowly than that from the p53+/+ population as shown in vivo using pre-spleen colony-forming unit (CFU-S) assay and in vitro using long-term culture-initiating cells (LTC-ICs) and methylcellulose replating assays. Fluorouracil 22-26 P53 Homo sapiens 35-38 9531612-9 1998 Despite all these changes and the dramatic difference in sensitivity of p53-/- and p53+/+ BMCs to 5-FU-induced apoptosis, lineage commitment and differentiation of hematopoietic progenitors appeared to be independent of p53 status. Fluorouracil 98-102 P53 Homo sapiens 72-75 9531612-9 1998 Despite all these changes and the dramatic difference in sensitivity of p53-/- and p53+/+ BMCs to 5-FU-induced apoptosis, lineage commitment and differentiation of hematopoietic progenitors appeared to be independent of p53 status. Fluorouracil 98-102 P53 Homo sapiens 83-86 9563466-1 1998 The death receptor (DR) KILLER/DR5 gene has recently been identified as a doxorubicin-regulated transcript that was also induced by exogenous wild-type p53 in p53-negative cells. Doxorubicin 74-85 P53 Homo sapiens 152-155 9531612-9 1998 Despite all these changes and the dramatic difference in sensitivity of p53-/- and p53+/+ BMCs to 5-FU-induced apoptosis, lineage commitment and differentiation of hematopoietic progenitors appeared to be independent of p53 status. Fluorouracil 98-102 P53 Homo sapiens 83-86 9563466-1 1998 The death receptor (DR) KILLER/DR5 gene has recently been identified as a doxorubicin-regulated transcript that was also induced by exogenous wild-type p53 in p53-negative cells. Doxorubicin 74-85 P53 Homo sapiens 159-162 9563490-7 1998 N-Acetylcysteine elevated p53 expression posttranscriptionally by increasing the rate of p53 mRNA translation rather than by altering the protein stability. Acetylcysteine 0-16 P53 Homo sapiens 26-29 9563490-7 1998 N-Acetylcysteine elevated p53 expression posttranscriptionally by increasing the rate of p53 mRNA translation rather than by altering the protein stability. Acetylcysteine 0-16 P53 Homo sapiens 89-92 9607618-9 1998 p53 mutant status was assessed immunohistochemically from sections of the formalin-fixed, paraffin-embedded pretreatment biopsy and the resected specimen. Paraffin 90-98 P53 Homo sapiens 0-3 9636834-1 1998 BACKGROUND: Alteration in apoptosis pathways (in particular mutations of p53 gene) may result in resistance of ovarian carcinoma to cisplatin. Cisplatin 132-141 P53 Homo sapiens 73-76 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 26-31 P53 Homo sapiens 100-103 9548807-9 1998 Inhibition of ROS production by the antioxidant enzyme catalase reduced AZQ- and DZQ-mediated p53 induction by about 45%. Reactive Oxygen Species 14-17 P53 Homo sapiens 94-97 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 26-31 P53 Homo sapiens 150-153 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 26-31 P53 Homo sapiens 150-153 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 232-237 P53 Homo sapiens 100-103 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 232-237 P53 Homo sapiens 150-153 9636834-18 1998 Finally, the finding that Taxol was very effective in inducing apoptosis in resistant sublines with p53 mutation supports the expression of an intact p53-independent pathway of apoptosis and suggests the pharmacological interest of Taxol in the treatment of p53-mutated tumors. Paclitaxel 232-237 P53 Homo sapiens 150-153 9548807-5 1998 In this study, we investigated the ability of diaziridinylbenzoquinones to increase p53 levels in the human breast cancer cell line MCF-7. diaziridinylbenzoquinones 46-71 P53 Homo sapiens 84-87 9546285-10 1998 Only one PCNSL showed a mutation of the TP53 gene, i.e., a missense mutation at codon 248 (CGG to TGG:Arg to Trp). Arginine 102-105 P53 Homo sapiens 40-44 9546285-10 1998 Only one PCNSL showed a mutation of the TP53 gene, i.e., a missense mutation at codon 248 (CGG to TGG:Arg to Trp). Tryptophan 109-112 P53 Homo sapiens 40-44 9529014-5 1998 Immunohistochemical staining of the paraffin sections was performed using monoclonal antibodies to cyclin E and p53. Paraffin 36-44 P53 Homo sapiens 112-115 9548807-11 1998 The nonalkylator oxygen-radical-generating agent menadione (MD) caused p53 induction only when MCF-7 cells were allowed to recover in drug-free media. Reactive Oxygen Species 17-31 P53 Homo sapiens 71-74 9553810-0 1998 Random nuclear p53 overexpression pattern in tamoxifen-mediated endometrial carcinoma. Tamoxifen 45-54 P53 Homo sapiens 15-18 9609668-0 1998 Simultaneous detection of p53 nuclear protein and chromosome aberrations on sections from formalin-fixed, paraffin-embedded breast cancer tissue. Paraffin 106-114 P53 Homo sapiens 26-29 9499438-0 1998 Upregulation of p21WAF1/CIP1 in human breast cancer cell lines MCF-7 and MDA-MB-468 undergoing apoptosis induced by natural product anticancer drugs 10-hydroxycamptothecin and camptothecin through p53-dependent and independent pathways. 10-hydroxycamptothecin 149-171 P53 Homo sapiens 197-200 9499438-6 1998 The levels of p53 and p21WAF1/CIP1 protein increased in MCF-7 cells treated with HCPT or CPT in a dose- and time-dependent manner. 10-hydroxycamptothecin 81-85 P53 Homo sapiens 14-17 9563876-15 1998 In the p53null SK-OV-3 xenograft model of ovarian cancer, a dosing schedule of p53 Ad that, by itself, had a relatively minimal effect on tumor burden (16%) caused a much greater decrease in tumor burden (55%) when combined with paclitaxel. Paclitaxel 229-239 P53 Homo sapiens 7-10 9563876-15 1998 In the p53null SK-OV-3 xenograft model of ovarian cancer, a dosing schedule of p53 Ad that, by itself, had a relatively minimal effect on tumor burden (16%) caused a much greater decrease in tumor burden (55%) when combined with paclitaxel. Paclitaxel 229-239 P53 Homo sapiens 79-82 9563876-17 1998 In summary, p53 Ad for cancer shows enhanced efficacy when combined with paclitaxel. Paclitaxel 73-83 P53 Homo sapiens 12-15 9563901-1 1998 In the present study, we report our findings on the impact of p53 disruption on the sensitivity of human cell lines to the antimitotic agents Taxol and vincristine. Paclitaxel 142-147 P53 Homo sapiens 62-65 9563901-5 1998 We also found that contrary to gamma-irradiation, Taxol and vincristine could induce apoptosis in lymphoma cell lines harboring p53 mutations. Paclitaxel 50-55 P53 Homo sapiens 128-131 9563901-9 1998 The effect of p53 disruption on Taxol sensitivity was explored further in the breast carcinoma MCF-7 and colon carcinoma HCT-116 cell lines that had been stably transfected with either the human papillomavirus type-16 E6 gene or a dominant-negative mutant p53 gene. Paclitaxel 32-37 P53 Homo sapiens 14-17 9535218-2 1998 We found that induction of apoptosis in Mphi by oxLDL, C2-ceramide, tumor necrosis factor alpha (TNF-alpha), and hydrogen peroxide (H2O2) was associated with enhanced expression of manganese superoxide dismutase (MnSOD) and p53. Hydrogen Peroxide 132-136 P53 Homo sapiens 224-227 9535218-3 1998 Treatment of cells with p53 or MnSOD antisense oligonucleotides prior to stimulation with oxLDL, C2-ceramide, TNF-alpha, or H2O2 caused an inhibition of the expression of the respective protein together with a marked reduction of apoptosis. Hydrogen Peroxide 124-128 P53 Homo sapiens 24-27 9535218-4 1998 Exposure to N-acetylcysteine before treatment with oxLDL, C2-ceramide, TNF-alpha, or H2O2 reversed a decrease in cellular glutathione concentrations as well as the enhanced production of p53 and MnSOD mRNA and protein. Acetylcysteine 12-28 P53 Homo sapiens 187-190 9535218-4 1998 Exposure to N-acetylcysteine before treatment with oxLDL, C2-ceramide, TNF-alpha, or H2O2 reversed a decrease in cellular glutathione concentrations as well as the enhanced production of p53 and MnSOD mRNA and protein. Hydrogen Peroxide 85-89 P53 Homo sapiens 187-190 9499438-11 1998 These results suggest that treatment with HCPT and CPT results in increased levels of p21WAF1/CIP1 protein and mRNA, and that they induce apoptosis in human breast cancer cells through both p53-dependent and -independent pathways. 10-hydroxycamptothecin 42-46 P53 Homo sapiens 190-193 9553810-6 1998 Diffuse and intense nuclear reactivity for p53 protein was present in only one TAM-related case. Tamoxifen 79-82 P53 Homo sapiens 43-46 10923485-2 1998 METHODS: The expression of HCV NS3 and P53 protein was detected by immuno-histochemical technique (SP method) in specimens of HCC and their surrounding liver tissues from 47 patients with negative HBV. TFF2 protein, human 99-101 P53 Homo sapiens 39-42 9515788-3 1998 We analyzed p53 mutations on paraffin-embedded specimens from 21 patients with PAL by PCR-single-strand conformational polymorphism followed by direct sequencing. Paraffin 29-37 P53 Homo sapiens 12-15 9506540-3 1998 When p53 was expressed at sublethal levels, it sensitized cells to the DNA-damaging drugs Adriamycin, mitomycin C, actinomycin D, etoposide (VP16), cisplatin and CPT11. Doxorubicin 90-100 P53 Homo sapiens 5-8 9506540-3 1998 When p53 was expressed at sublethal levels, it sensitized cells to the DNA-damaging drugs Adriamycin, mitomycin C, actinomycin D, etoposide (VP16), cisplatin and CPT11. Cisplatin 148-157 P53 Homo sapiens 5-8 9506540-3 1998 When p53 was expressed at sublethal levels, it sensitized cells to the DNA-damaging drugs Adriamycin, mitomycin C, actinomycin D, etoposide (VP16), cisplatin and CPT11. Irinotecan 162-167 P53 Homo sapiens 5-8 9515799-12 1998 In stage III, adjuvant therapy with 5FU plus levamisole improved 7-year survival in patients with wild-type Ki-ras (76 versus 44%; HR, 0.4; 95% CI, 0.2-0.8) and in those without p53 overexpression (64 versus 26%; HR, 0.3; 95% CI, 0.1-0.7). Fluorouracil 36-39 P53 Homo sapiens 178-181 9546425-1 1998 Using UvrABC incision in combination with ligation-mediated PCR (LMPCR) we have previously shown that benzo(a)pyrene diol epoxide (BPDE) adduct formation along the nontranscribed strand of the human p53 gene is highly selective; the preferential binding sites coincide with the major mutation hotspots found in human lung cancers. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 102-129 P53 Homo sapiens 199-202 9546425-1 1998 Using UvrABC incision in combination with ligation-mediated PCR (LMPCR) we have previously shown that benzo(a)pyrene diol epoxide (BPDE) adduct formation along the nontranscribed strand of the human p53 gene is highly selective; the preferential binding sites coincide with the major mutation hotspots found in human lung cancers. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 131-135 P53 Homo sapiens 199-202 9519827-6 1998 However, p53 is only degraded early in the infectious cycle due to a lack of ATP at later times. Adenosine Triphosphate 77-80 P53 Homo sapiens 9-12 9528861-2 1998 In the HCT116 colon carcinoma cell line, which retains a wild-type inducible p53 gene, we show that the anthracycline daunomycin is a potent inducer of p53 and NF-kappaB transcription factors. Anthracyclines 104-117 P53 Homo sapiens 77-80 9528861-2 1998 In the HCT116 colon carcinoma cell line, which retains a wild-type inducible p53 gene, we show that the anthracycline daunomycin is a potent inducer of p53 and NF-kappaB transcription factors. Anthracyclines 104-117 P53 Homo sapiens 152-155 9492043-5 1998 Similarly, wild-type p53 decreased IGF-I-induced tyrosine phosphorylation of IRS-1. Tyrosine 49-57 P53 Homo sapiens 21-24 9492043-10 1998 In conclusion, p53 regulates IGF-IR expression, as reflected by a reduction in IGF-IR protein and a parallel reduction in IGF-I-induced tyrosine phosphorylation of the IGF-IR and IRS-1 in an osteosarcoma cell line. Tyrosine 136-144 P53 Homo sapiens 15-18 9488661-7 1998 The results suggest that p53 can form disulfides and that these disulfides must be reduced in order for the protein to function as a transcription factor. Disulfides 38-48 P53 Homo sapiens 25-28 9488661-7 1998 The results suggest that p53 can form disulfides and that these disulfides must be reduced in order for the protein to function as a transcription factor. Disulfides 64-74 P53 Homo sapiens 25-28 9578140-6 1998 Upon treatment with epidermal growth factor (EGF) and dibutyrylcyclic AMP, overall cytoplasmic GFAP and GS levels were increased while nuclear p53 was suppressed but a mutually exclusive expression pattern between these proteins was maintained. Adenosine Monophosphate 70-73 P53 Homo sapiens 143-146 9492043-0 1998 p53 regulates insulin-like growth factor-I (IGF-I) receptor expression and IGF-I-induced tyrosine phosphorylation in an osteosarcoma cell line: interaction between p53 and Sp1. Tyrosine 89-97 P53 Homo sapiens 0-3 9472095-1 1998 The polymorphism of p53 gene at codon 72 consisting of either arginine (Arg)- or proline (Pro)-encoded allele is suggested to be associated with the susceptibility of tobacco-related lung cancer. Arginine 62-70 P53 Homo sapiens 20-23 9472095-1 1998 The polymorphism of p53 gene at codon 72 consisting of either arginine (Arg)- or proline (Pro)-encoded allele is suggested to be associated with the susceptibility of tobacco-related lung cancer. Arginine 72-75 P53 Homo sapiens 20-23 9472102-9 1998 In a cell clone derived from line VMCub1 by stable transfection with wild-type p53 under the control of a metallothionein promotor, p21 was induced along with p53 upon activation of the promoter with zinc chloride. zinc chloride 200-213 P53 Homo sapiens 79-82 9472102-9 1998 In a cell clone derived from line VMCub1 by stable transfection with wild-type p53 under the control of a metallothionein promotor, p21 was induced along with p53 upon activation of the promoter with zinc chloride. zinc chloride 200-213 P53 Homo sapiens 159-162 9488455-5 1998 Unexpectedly, UVC treatment was also found to block the induction of p21Waf1 by various stress-inducing agents such as mimosine in the p53-deficient cells. Mimosine 119-127 P53 Homo sapiens 135-138 9740272-3 1998 One case harbored a p53 gene mutation in codon 282 in exon 8, CGG (arginine) to TGG (tryptophan), but the mutation was not found in other patient"s tissues with similar histological features. Arginine 67-75 P53 Homo sapiens 20-23 9682769-6 1998 p53 protein expression was evaluated by immunohistochemistry (IHC) on paraffin-embedded sections. Paraffin 70-78 P53 Homo sapiens 0-3 9499782-15 1998 This mutation, characteristic of bulky carcinogens, substituted phenylalanine for cysteine 277, a residue that participates in hydrogen bonding to the p53 DNA binding consensus sequence. Hydrogen 127-135 P53 Homo sapiens 151-154 9740272-3 1998 One case harbored a p53 gene mutation in codon 282 in exon 8, CGG (arginine) to TGG (tryptophan), but the mutation was not found in other patient"s tissues with similar histological features. Tryptophan 85-95 P53 Homo sapiens 20-23 9485322-8 1998 In this paper, we report that S100B(beta beta) binds to the p53 peptide (CaK3 < or = 23.5 +/- 6.6 microM) in a Ca(2+)-dependent manner, and that the presence of the p53 peptide was found to increase the binding affinity of Ca2+ to S100B(beta beta) by 3-fold using EPR and PRR methods, whereas the peptide had no effect on Zn2+ binding to S100B(beta beta). Zinc 325-329 P53 Homo sapiens 60-63 10920952-3 1998 RESULTS: p53 gene mutation was detected in 60.1% of cancer, 31.3% of Dys and 11.8% of IM. dys 69-72 P53 Homo sapiens 9-12 9479003-4 1998 Moreover, we established that 3-methyladenine, a relatively minor DNA lesion produced by most methylating agents (which form mainly 7-methylguanine), can specifically induce sister chromatid exchange, chromatid and chromosome gaps and breaks, S phase arrest, the accumulation of p53, and apoptosis. 3-methyladenine 30-45 P53 Homo sapiens 279-282 9454845-9 1998 The glutamate-induced increase in Bax protein was dependent on the presence of the p53 gene. Glutamic Acid 4-13 P53 Homo sapiens 83-86 9485023-0 1998 Independent pathways of p53 induction by cisplatin and X-rays in a cisplatin-resistant ovarian tumor cell line. Cisplatin 41-50 P53 Homo sapiens 24-27 9485023-0 1998 Independent pathways of p53 induction by cisplatin and X-rays in a cisplatin-resistant ovarian tumor cell line. Cisplatin 67-76 P53 Homo sapiens 24-27 9485023-2 1998 Our studies were initiated by asking whether the translational product of the p53 gene is associated with cisplatin resistance in the 2780CP human ovarian tumor model. Cisplatin 106-115 P53 Homo sapiens 78-81 9485023-3 1998 We have demonstrated by single-strand conformation polymorphism analysis and sequencing that p53 in parental cisplatin-sensitive A2780 cells was wild type. Cisplatin 109-118 P53 Homo sapiens 93-96 9485023-9 1998 In parallel investigations using the Western technique, exposure of A2780 cells to clinically relevant concentrations of cisplatin (1-20 microM) resulted in time- and dose-dependent increases in p53, together with coordinate increases in p21Waf1/Cip1. Cisplatin 121-130 P53 Homo sapiens 195-198 9485023-11 1998 The results indicate that a defect exists in the signal transduction pathway for p53 induction following cisplatin-induced DNA damage in 2780CP cells, and this may represent a significant mechanism of cisplatin resistance. Cisplatin 105-114 P53 Homo sapiens 81-84 9485023-11 1998 The results indicate that a defect exists in the signal transduction pathway for p53 induction following cisplatin-induced DNA damage in 2780CP cells, and this may represent a significant mechanism of cisplatin resistance. Cisplatin 201-210 P53 Homo sapiens 81-84 9472015-5 1998 We demonstrate that recombinant His-tagged HMG-1 enhances p53 DNA binding in vitro and also that HMG-1 and p53 can interact directly in vitro. Histidine 32-35 P53 Homo sapiens 58-61 9472015-5 1998 We demonstrate that recombinant His-tagged HMG-1 enhances p53 DNA binding in vitro and also that HMG-1 and p53 can interact directly in vitro.

Morphine 0-8 P53 Homo sapiens 43-46 9453486-1 1998 BACKGROUND & AIMS: The p53 and BAX genes have been linked to apoptosis. Adenosine Monophosphate 12-15 P53 Homo sapiens 27-30 9469450-13 1998 These studies suggest that morphine activates the induction phase of the apoptotic pathway through accumulation of p53. Morphine 27-35 P53 Homo sapiens 115-118 9490416-4 1998 Using a chimaeric p53 fusion protein with the oestrogen receptor (p53ER) to supply p53 (p53 is induced upon binding of p53ER to oestradiol) in a p53-deficient cell line, we found that p85 is upregulated by p53 and that its involvement in p53-mediated apoptosis is independent of PI(3)K. We propose that p85 acts as a signal transducer in the cellular response to oxidative stress, mediating cell death regulated by p53.

Estradiol 128-138 P53 Homo sapiens 66-69 9461094-7 1998 Morphine at concentrations of 10(-8) to 10(-4) M promoted apoptosis of kidney fibroblasts and also enhanced the synthesis of p53 by kidney fibroblasts. Morphine 0-8 P53 Homo sapiens 125-128 9461094-8 1998 We speculate that morphine-induced kidney fibroblast proliferation may be mediated through the activation of early growth related genes, whereas morphine induced kidney fibroblast apoptosis may be mediated through the generation of p53. Morphine 145-153 P53 Homo sapiens 232-235 9468185-8 1998 Cell death of p53-transduced VSMCs was induced only by additional treatment with an apoptosis-stimulating reagent, doxorubicin. Doxorubicin 115-126 P53 Homo sapiens 14-17 9530523-8 1998 The results of these experiments demonstrate that: (1) there were mutations in p53 exon 5 and 8 in 35% (14 out of 40 samples) of human renal cancer tissues as revealed by PCR-SSCP analysis; (2) DNA sequencing of samples showing frame-shift have hot spot of p53 mutation on exon 8 at codon 244 (GGC-->TGC) and exon 5 at codon 132 [AAG (Lys)-->AGG (Arg)]. Lysine 338-341 P53 Homo sapiens 79-82 9530523-8 1998 The results of these experiments demonstrate that: (1) there were mutations in p53 exon 5 and 8 in 35% (14 out of 40 samples) of human renal cancer tissues as revealed by PCR-SSCP analysis; (2) DNA sequencing of samples showing frame-shift have hot spot of p53 mutation on exon 8 at codon 244 (GGC-->TGC) and exon 5 at codon 132 [AAG (Lys)-->AGG (Arg)]. Arginine 353-356 P53 Homo sapiens 79-82 9458352-0 1998 Role of p53 and apoptosis in sensitization of cis-diamminedichloroplatinum antitumor activity by interleukin-1 in ovarian carcinoma cells. Cisplatin 46-74 P53 Homo sapiens 8-11 9458352-4 1998 IL-1 and CDDP treatment induced p53 protein in NIH:OVCAR-3 tumor cells. Cisplatin 9-13 P53 Homo sapiens 32-35 9458352-7 1998 The synergistic interactions of IL-1 with CDDP may involve the enhancement of p53-dependent apoptosis. Cisplatin 42-46 P53 Homo sapiens 78-81 9548450-1 1998 It has been controversial whether cancer cells harboring loss or inactivation of the tumor suppressor p53 are resistant or sensitive to DNA-damaging agents including cisplatin and doxorubicin. Cisplatin 166-175 P53 Homo sapiens 102-105 9548450-1 1998 It has been controversial whether cancer cells harboring loss or inactivation of the tumor suppressor p53 are resistant or sensitive to DNA-damaging agents including cisplatin and doxorubicin. Doxorubicin 180-191 P53 Homo sapiens 102-105 9548451-3 1998 Immunocytochemical analysis demonstrated that MDM2-positive tumors, even with p53-negative phenotype, were significantly more resistant to doxorubicin treatment compared to MDM2-negative tumors. Doxorubicin 139-150 P53 Homo sapiens 78-81 9508372-3 1998 Cisplatin, at 10 microM, virtually killed all the cells in the wild-type p53 cell lines, while 57-95% of the cells in the mutant p53 cell lines survived (P = 0.005). Cisplatin 0-9 P53 Homo sapiens 73-76 9508372-8 1998 Cisplatin, camptothecin and vincristine all induced apoptosis in wild-type p53 melanoma cells, but not in mutant p53 cells. Cisplatin 0-9 P53 Homo sapiens 75-78 9510045-3 1998 MATERIALS AND METHODS: Immunostaining for p53 protein was performed on paraffin-embedded specimens from 69 patients with adeno- and squamous cell carcinoma of the oesophagus. Paraffin 71-79 P53 Homo sapiens 42-45 9455805-3 1998 Here, using normal human fibroblasts (NHFs), we show that cisplatin and UV radiation induce G2/M arrest which is temporally linked to p53-protein induction. Cisplatin 58-67 P53 Homo sapiens 134-137 9455805-4 1998 To study the contribution of p53 to this G2/M arrest, we inhibited p53 induction in NHFs using p53 anti-sense oligonucleotides. Oligonucleotides 110-126 P53 Homo sapiens 67-70 9464250-2 1998 We used doxorubicin (DOX) and sodium butyrate (NaB) to accumulate p53 protein. Doxorubicin 8-19 P53 Homo sapiens 66-69 9464250-2 1998 We used doxorubicin (DOX) and sodium butyrate (NaB) to accumulate p53 protein. Doxorubicin 21-24 P53 Homo sapiens 66-69 9464250-4 1998 P53 protein induction in response to DOX accompanied up-regulation of p21/waf-1 and cyclinG expression. Doxorubicin 37-40 P53 Homo sapiens 0-3 9455805-4 1998 To study the contribution of p53 to this G2/M arrest, we inhibited p53 induction in NHFs using p53 anti-sense oligonucleotides. Oligonucleotides 110-126 P53 Homo sapiens 67-70 9445187-12 1998 CONCLUSIONS: In this study, p53p overexpression was infrequent in paraffin embedded melanoma specimens and independent of the primary melanoma"s anatomic site. Paraffin 66-74 P53 Homo sapiens 28-32 9467949-4 1998 The p34cdc2 binding site on human p53 maps to one distinct C-terminal site LQIRGRERFE (aa 330-339) close to the corresponding phosphorylation site at serine 315. Serine 150-156 P53 Homo sapiens 34-37 10069444-5 1998 In one case, p53 codon 282 mutation (CGG-->TGG; arg-->trp) were observed in initial diagnosis. Arginine 51-54 P53 Homo sapiens 13-16 9580543-4 1998 Expression of mutant p53 was evaluated in 655 human breast carcinomas (349 node-positive and 306 node-negative patients) with long-term clinical follow-up by immunohistochemistry in sections from paraffin embedded tumors. Paraffin 196-204 P53 Homo sapiens 21-24 9472635-6 1998 Similarly, high concentrations of taxol were required to induce p53 activity in the p53 wild-type cell line LN-229. Paclitaxel 34-39 P53 Homo sapiens 64-67 9472635-6 1998 Similarly, high concentrations of taxol were required to induce p53 activity in the p53 wild-type cell line LN-229. Paclitaxel 34-39 P53 Homo sapiens 84-87 9516963-3 1998 A wtp53 cDNA was subcloned into the pGRE5-2/EBV vector with dexamethasone-inducible overexpression and transfected into Rh30 ARMS cells that express Pax3/FKHR and a mutant p53 phenotype. Dexamethasone 60-73 P53 Homo sapiens 4-7 9516963-6 1998 Data demonstrated p53-dependent sensitization (> or = 4-fold) to bleomycin, actinomycin D, and 5-fluorouracil and considerably less p53-dependence (< or = 2-fold) for doxorubicin, topotecan, etoposide, and cisplatin in Cl.#27 compared to an equivalent clone containing the pGRE5-EBV vector alone (VC#3). Fluorouracil 98-112 P53 Homo sapiens 18-21 9773296-1 1998 Immunohistochemical detection of p53 in paraffin-embedded biopsy specimens has important diagnostic, prognostic and therapeutic applications. Paraffin 40-48 P53 Homo sapiens 33-36 9773296-8 1998 The most suitable fixatives for immunohistochemical detection of p53 are 70% ethanol and Carnoy solution. Ethanol 77-84 P53 Homo sapiens 65-68 9618042-3 1998 We set out to determine whether p53 overexpression of the colorectum was associated with a patient"s history of aspirin use. Aspirin 112-119 P53 Homo sapiens 32-35 9618042-9 1998 An inverse association of regular aspirin use (two times per week or more) was found both for cases with p53 overexpression (OR: 0.79; 95% CI: 0.39-1.59), and for cases without p53 overexpression (OR: 0.56; 95% CI: 0.25-1.22). Aspirin 34-41 P53 Homo sapiens 105-108 9618042-9 1998 An inverse association of regular aspirin use (two times per week or more) was found both for cases with p53 overexpression (OR: 0.79; 95% CI: 0.39-1.59), and for cases without p53 overexpression (OR: 0.56; 95% CI: 0.25-1.22). Aspirin 34-41 P53 Homo sapiens 177-180 9464331-10 1998 Accordingly, consolidation chemotherapy is necessary for patients with stage I a who are positive p53 and highly PA. Platinum-based chemotherapy for patients who had minimal residual tumor was effective, but 5 patients who had > or = 2 cm tumor burden were not effective at all. Platinum 117-125 P53 Homo sapiens 98-101 9464331-11 1998 The response rate for platinum-based chemotherapy was 20% (1/5) among p53 positive, in contrast to 66.7% (4/6) among p53 negative patients. Platinum 22-30 P53 Homo sapiens 70-73 9474928-5 1998 Restoration of wild-type p53 function markedly enhanced the antitumor effect of a common chemotherapeutic agent, cisplatin, in human non-small cell lung cancer cells as well as human colon cancer cells. Cisplatin 113-122 P53 Homo sapiens 25-28 10069444-5 1998 In one case, p53 codon 282 mutation (CGG-->TGG; arg-->trp) were observed in initial diagnosis. Tryptophan 60-63 P53 Homo sapiens 13-16 9719502-4 1998 In addition, p53 protein overexpression was assessed by immunohistochemistry using the monoclonal antibody DO-7 on paraffin-embedded tissue sections. Paraffin 115-123 P53 Homo sapiens 13-16 9498829-7 1998 Interestingly, apoptosis occurred in mt-p53 tumors although only at high doses of cisplatin and not at the magnitude detected in wt-p53 tumors. Cisplatin 82-91 P53 Homo sapiens 40-43 9718082-8 1998 An increase in the level of immunophenotypic expression of wild type p53 was also noted after treatment with all trans retinoic acid and 9-cis retinoic acid. Tretinoin 119-132 P53 Homo sapiens 69-72 9440732-0 1998 p53 protein accumulation predicts poor response to tamoxifen therapy of patients with recurrent breast cancer. Tamoxifen 51-60 P53 Homo sapiens 0-3 9440732-3 1998 We studied whether p53 protein accumulation is a predictive factor for response to tamoxifen treatment in patients with recurrent breast cancer. Tamoxifen 83-92 P53 Homo sapiens 19-22 9440732-8 1998 In a test for trend, we observed an association of p53 protein levels with response to tamoxifen therapy. Tamoxifen 87-96 P53 Homo sapiens 51-54 9440732-11 1998 Also in multivariate analysis, reduced survival after the start of tamoxifen therapy was observed in the p53-high group (relative hazards rate [RHR], 1.56, 95% CI, 1.17 to 2.10; P = .002). Tamoxifen 67-76 P53 Homo sapiens 105-108 9440732-12 1998 A statistically significant association between p53 levels and decreased tamoxifen response was seen only in the subset of patients whose tumors expressed low levels of ER or PgR (<75 fmol/mg protein). Tamoxifen 73-82 P53 Homo sapiens 48-51 9440732-13 1998 CONCLUSION: Measurement of primary tumor p53 levels may be effective in predicting response to tamoxifen therapy in recurrent breast disease. Tamoxifen 95-104 P53 Homo sapiens 41-44 9436988-6 1998 Because of the role of IMPD in the production and balance of GTP and ATP, essential nucleotides for signal transduction, these results suggest that p53 controls cell division signals by regulating purine ribonucleotide metabolism. Guanosine Triphosphate 61-64 P53 Homo sapiens 148-151 9436988-6 1998 Because of the role of IMPD in the production and balance of GTP and ATP, essential nucleotides for signal transduction, these results suggest that p53 controls cell division signals by regulating purine ribonucleotide metabolism. Adenosine Triphosphate 69-72 P53 Homo sapiens 148-151 9482165-11 1998 These results coupled with the observation that various fatty acids can alter the activity of cell membrane bound enzymes such as sodium-potassium-ATPase and 5"-nucleotidase, levels of various anti-oxidants, p53 expression and the concentrations of protein kinase C suggest that essential fatty acids and their metabolites can reverse tumour cell drug-resistance at least in vitro. Fatty Acids 56-67 P53 Homo sapiens 208-211 9460707-0 1998 Nitric oxide donor-induced p53-sensitive cell death is enhanced by Bcl-2 reduction in human neuroblastoma cells. Nitric Oxide 0-12 P53 Homo sapiens 27-30 9700726-0 1998 DNA binding activities of p53 protein following cisplatin damage of ovarian cells. Cisplatin 48-57 P53 Homo sapiens 26-29 9700726-1 1998 In this study the transactivation potential and DNA binding activities of p53 protein were examined following exposure of A2780 cells, a human ovarian carcinoma cell line, to the DNA damaging agent, cis-diamminedichloroplatinum II (cisplatin). Cisplatin 199-230 P53 Homo sapiens 74-77 9700726-1 1998 In this study the transactivation potential and DNA binding activities of p53 protein were examined following exposure of A2780 cells, a human ovarian carcinoma cell line, to the DNA damaging agent, cis-diamminedichloroplatinum II (cisplatin). Cisplatin 232-241 P53 Homo sapiens 74-77 9700726-7 1998 At low doses of cisplatin, these latent pools of p53 increased in parallel with mdm-2 gene activation and were detectable as early as 4 h following cisplatin treatment. Cisplatin 16-25 P53 Homo sapiens 49-52 9700726-7 1998 At low doses of cisplatin, these latent pools of p53 increased in parallel with mdm-2 gene activation and were detectable as early as 4 h following cisplatin treatment. Cisplatin 148-157 P53 Homo sapiens 49-52 9700726-9 1998 Even though cisplatin-induced p53 lacked sequence-specific DNA binding activity, it does possess an increased affinity for cisplatin-damaged duplex DNA molecules. Cisplatin 12-21 P53 Homo sapiens 30-33 9700726-9 1998 Even though cisplatin-induced p53 lacked sequence-specific DNA binding activity, it does possess an increased affinity for cisplatin-damaged duplex DNA molecules. Cisplatin 123-132 P53 Homo sapiens 30-33 9700726-10 1998 This represents the first identification where cisplatin treatment induces a p53 protein, lacking sequence-specific DNA binding but with an increased affinity for platinated DNA molecules. Cisplatin 47-56 P53 Homo sapiens 77-80 9405613-6 1997 One Zn2+ ion remains tightly bound in the holo-form of p53 throughout the denaturation curve. Zinc 4-8 P53 Homo sapiens 55-58 15678851-4 1998 In this study we analyzed the expression of p53 protein in a variety of salivary gland malignant tumors fixed in formalin and included in paraffin, using the method of immunohistochemical coloring with the anti-p53 DO-7 antibody. Paraffin 138-146 P53 Homo sapiens 44-47 9405685-6 1997 Like p53, p53CP also binds both double- and single-stranded DNA oligonucleotides. Oligonucleotides 64-80 P53 Homo sapiens 5-8 15678854-6 1998 Immunohistochemical determination of p53 protein was performed on tissular samples formalin fixed and paraffin embedded, using mouse monoclonal antibody DAKO--p53 DO 7 p53 human antiprotein. Paraffin 102-110 P53 Homo sapiens 37-40 9776848-10 1998 Neither neonatal nor normal adult skin fibroblasts expressed either antigen but could be induced to express p53 by exposure to adriamycin. Doxorubicin 127-137 P53 Homo sapiens 108-111 9461043-16 1997 Our results suggest that CAP induces apoptotic cell death in human gastric cancer cells (SNU-1) in vitro which may be possibly mediated by the overexpression of p53 and/or c-myc genes. Capsaicin 25-28 P53 Homo sapiens 161-164 9459175-0 1997 Relationship between nitrogen mustard drug resistance in B-cell chronic lymphocytic leukemia (B-CLL) and protein expression of Bcl-2, Bax, Bcl-X and p53. Nitrogen 21-29 P53 Homo sapiens 149-152 9407038-3 1997 This peptide represents the first 24 amino acids of p53 and contains three phosphorylated serine residues. Serine 90-96 P53 Homo sapiens 52-55 9407038-4 1997 A specific p53 phosphopeptide antibody identified serine-15 as one of the two serines in p53 that becomes phosphorylated following DNA damage induced by either ionizing irradiation (IR) or ultraviolet (UV) irradiation in multiple cell types. Serine 50-56 P53 Homo sapiens 11-14 9407038-4 1997 A specific p53 phosphopeptide antibody identified serine-15 as one of the two serines in p53 that becomes phosphorylated following DNA damage induced by either ionizing irradiation (IR) or ultraviolet (UV) irradiation in multiple cell types. Serine 50-56 P53 Homo sapiens 89-92 9407038-4 1997 A specific p53 phosphopeptide antibody identified serine-15 as one of the two serines in p53 that becomes phosphorylated following DNA damage induced by either ionizing irradiation (IR) or ultraviolet (UV) irradiation in multiple cell types. Serine 78-85 P53 Homo sapiens 11-14 9407038-4 1997 A specific p53 phosphopeptide antibody identified serine-15 as one of the two serines in p53 that becomes phosphorylated following DNA damage induced by either ionizing irradiation (IR) or ultraviolet (UV) irradiation in multiple cell types. Serine 78-85 P53 Homo sapiens 89-92 9407038-8 1997 In contrast, phosphorylation of p53 on serine-15 is similar in normal and AT cells after UV irradiation. Serine 39-45 P53 Homo sapiens 32-35 9407038-9 1997 Our results indicate that p53 is phosphorylated in response to DNA damage, that this de novo phosphorylation may be involved in the subsequent induction and activation of p53, and that although ATM affects the kinetics of p53 phosphorylation after IR, it is not absolutely required for phosphorylation of p53 on serine-15. Serine 312-318 P53 Homo sapiens 26-29 9407038-9 1997 Our results indicate that p53 is phosphorylated in response to DNA damage, that this de novo phosphorylation may be involved in the subsequent induction and activation of p53, and that although ATM affects the kinetics of p53 phosphorylation after IR, it is not absolutely required for phosphorylation of p53 on serine-15. Serine 312-318 P53 Homo sapiens 171-174 9407038-9 1997 Our results indicate that p53 is phosphorylated in response to DNA damage, that this de novo phosphorylation may be involved in the subsequent induction and activation of p53, and that although ATM affects the kinetics of p53 phosphorylation after IR, it is not absolutely required for phosphorylation of p53 on serine-15. Serine 312-318 P53 Homo sapiens 171-174 9407038-9 1997 Our results indicate that p53 is phosphorylated in response to DNA damage, that this de novo phosphorylation may be involved in the subsequent induction and activation of p53, and that although ATM affects the kinetics of p53 phosphorylation after IR, it is not absolutely required for phosphorylation of p53 on serine-15. Serine 312-318 P53 Homo sapiens 171-174 9416838-4 1997 In this study we addressed the possible prognostic value of the molecular alterations identified in exons 5-8 of the TP53 gene in DNAs from 151 paraffin-embedded NSCLC sections corresponding to 59 Spanish and 92 Polish stage I-IIIA resected patients. Paraffin 144-152 P53 Homo sapiens 117-121 9415415-5 1997 MCF-7 cells showed a block in the G1 phase after treatment with 50 nM epirubicin for 24 hours, in agreement with the actions of p53 at the G1 checkpoint. Epirubicin 70-80 P53 Homo sapiens 128-131 9373250-10 1997 p53-specific antisense oligonucleotide treatment recapitulated the effects of Tpo treatment on the levels of Bax, Mdm-2, and Bcl-2. Oligonucleotides 23-38 P53 Homo sapiens 0-3 9409811-7 1997 Moreover, addition of glutathione monoethylester to the culture restored the level of reduced glutathione in VSM cells, and prevented the NO-induced increase in p53 expression and programmed cell death. S-ethyl glutathione 22-48 P53 Homo sapiens 161-164 9372954-7 1997 We have mapped a major site of phosphorylation by CAK to Ser-33 of p53 and have demonstrated as well that p53 is phosphorylated at this site in vivo. Serine 57-60 P53 Homo sapiens 67-70 9372954-7 1997 We have mapped a major site of phosphorylation by CAK to Ser-33 of p53 and have demonstrated as well that p53 is phosphorylated at this site in vivo. Serine 57-60 P53 Homo sapiens 106-109 9392545-0 1997 Original p53 status predicts for pathological response in locally advanced breast cancer patients treated preoperatively with continuous infusion 5-fluorouracil and radiation therapy. Fluorouracil 146-160 P53 Homo sapiens 9-12 10374328-2 1997 METHODS: The expression of p53 protein was determined in the paraffin embedded tissues of 171 cases of cervical carcinoma, 68 cases of SIL and 29 cases of chronic cervicitis, using ABC immunohistochemical method. Paraffin 61-69 P53 Homo sapiens 27-30 9409811-7 1997 Moreover, addition of glutathione monoethylester to the culture restored the level of reduced glutathione in VSM cells, and prevented the NO-induced increase in p53 expression and programmed cell death. Glutathione 22-33 P53 Homo sapiens 161-164 9403032-7 1997 Since HeLa cells lost most of their p53 protein due to a specific E6-dependent degradation, cisplatin could be inhibiting this degradation, since the p53 total levels were not increased during the exposure to the drug. Cisplatin 92-101 P53 Homo sapiens 150-153 9389577-6 1997 We further demonstrated that the p53-independent differential cisplatin sensitivity among the testicular germ cell tumour (TGCT) cell lines was not due to differences in cellular cisplatin accumulation or DNA platination. Cisplatin 62-71 P53 Homo sapiens 33-36 9389577-9 1997 We conclude that the cisplatin-induced apoptotic pathway in TGCT cell lines might be p53-independent and is probably not associated with differences in the Bcl-2/Bax rheostat. Cisplatin 21-30 P53 Homo sapiens 85-88 9570369-4 1997 In wt-p53 transfected cells, the expression of MDRI gene was significantly increased, accumulation of adriamycin (ADM) was decreased, and the sensitivity to vincristine (VCR), ADM and 5-fluorouracil (5-FU) was increased compared with the parent KBv200 cells. Doxorubicin 102-112 P53 Homo sapiens 6-9 9395239-8 1997 Introduction of functional p53 into CEM cells enhanced their sensitivity to the DNA-damaging agent doxorubicin, but not to the tubulin-active compound vincristine. Doxorubicin 99-110 P53 Homo sapiens 27-30 9570369-4 1997 In wt-p53 transfected cells, the expression of MDRI gene was significantly increased, accumulation of adriamycin (ADM) was decreased, and the sensitivity to vincristine (VCR), ADM and 5-fluorouracil (5-FU) was increased compared with the parent KBv200 cells. Fluorouracil 184-198 P53 Homo sapiens 6-9 9570369-4 1997 In wt-p53 transfected cells, the expression of MDRI gene was significantly increased, accumulation of adriamycin (ADM) was decreased, and the sensitivity to vincristine (VCR), ADM and 5-fluorouracil (5-FU) was increased compared with the parent KBv200 cells. Fluorouracil 200-204 P53 Homo sapiens 6-9 9467850-3 1997 The first of these TPA states is senescence, and several recent studies have shown that abrogation of p53 function permits temporary escape from senescence that ends in a poorly characterized form of arrest (referred to as p53-minus TPA) in which the pRB and p16INK4 genes appear to be involved. Tetradecanoylphorbol Acetate 19-22 P53 Homo sapiens 102-105 9359484-4 1997 Treatment with the chemotherapeutic drug cisplatin following infection with a replication-deficient, recombinant adenoviral vector expressing wt-p53 (termed AdCMVp53) significantly suppressed the growth of WiDr cells compared to single treatments alone. Cisplatin 41-50 P53 Homo sapiens 145-148 9366703-12 1997 A significant correlation existed with both p53 gene mutation status and HPV status with respect to alcohol and tobacco use. Alcohols 100-107 P53 Homo sapiens 44-47 9366703-13 1997 The presence of the p53 gene mutation positively correlated with increased tobacco and alcohol use, whereas infection with HPV predicted a significantly lower rate of alcohol and tobacco consumption. Alcohols 87-94 P53 Homo sapiens 20-23 9366703-15 1997 Conversely, there is a strong association between heavy alcohol and tobacco use and mutation of the p53 gene. Alcohols 56-63 P53 Homo sapiens 100-103 9494587-2 1997 We investigated the localization of p53 protein in association with HPV in paraffin sections of 10 dysplastic and 12 malignant laryngeal squamous epithelium specimens by using immunohistochemical and in situ hybridization techniques. Paraffin 75-83 P53 Homo sapiens 36-39 9467850-3 1997 The first of these TPA states is senescence, and several recent studies have shown that abrogation of p53 function permits temporary escape from senescence that ends in a poorly characterized form of arrest (referred to as p53-minus TPA) in which the pRB and p16INK4 genes appear to be involved. Tetradecanoylphorbol Acetate 233-236 P53 Homo sapiens 102-105 9815592-6 1997 The SKOV3ip1 cells do not express p53 protein; hence, the induction of apoptosis by paclitaxel is through a p53-independent pathway. Paclitaxel 84-94 P53 Homo sapiens 108-111 9354463-0 1997 Betulinic acid triggers CD95 (APO-1/Fas)- and p53-independent apoptosis via activation of caspases in neuroectodermal tumors. betulinic acid 0-14 P53 Homo sapiens 46-49 9449526-8 1997 EMSA of an oligonucleotide sequence derived from the HIV-LTR sequence demonstrated a slight decrease in Sp1 DNA binding activity with nuclear extract derived from the cell line expressing a high level of wild-type p53. Oligonucleotides 11-26 P53 Homo sapiens 214-217 9354463-3 1997 BA-induced apoptosis was independent of CD95-ligand/receptor interaction and accumulation of wild-type p53 protein, but it critically depended on activation of caspases (interleukin 1beta-converting enzyme/Ced-3-like proteases). betulinic acid 0-2 P53 Homo sapiens 103-106 9536982-3 1997 In this study, we have analysed the relationships between p53 protein induction, cell cycle arrest and cell survival following exposure of normal human fibroblasts (NHFs) to various genotoxic agents such as cisplatin, UV radiation and gamma radiation. Cisplatin 207-216 P53 Homo sapiens 58-61 9536982-5 1997 However, following inhibition of p53 induction by an antisense oligonucleotide, this G2/M arrest is even more important and correlates with an enhanced sensitivity of NHFs to UV radiation. Oligonucleotides 63-78 P53 Homo sapiens 33-36 9815601-11 1997 p53 wild-type cells seem to be more sensitive to the cytotoxic effects of the combination of UCN-01 + CDDP than the p53 mutant cells. Cisplatin 102-106 P53 Homo sapiens 0-3 9815601-12 1997 This was confirmed in cells in which p53 wild-type function was restored by transfection of p53 cDNA, but these cells are also significantly more sensitive to CDDP alone. Cisplatin 159-163 P53 Homo sapiens 37-40 9815601-10 1997 The degree of sensitization to CDDP conferred by UCN-01, however, was found to correlate with p53 gene status. Cisplatin 31-35 P53 Homo sapiens 94-97 9397628-4 1997 Paraffin-embedded tissue blocks of surgical margins from 24 patients with oral cavity and oropharyngeal squamous cell carcinoma were immunostained for p53 protein. Paraffin 0-8 P53 Homo sapiens 151-154 9470815-0 1997 Short- and long-term oestradiol treatment inhibits growth and alters expression of p21WAF1/Cip1 in an endometrial adenocarcinoma cell line lacking functional p53. Estradiol 21-31 P53 Homo sapiens 158-161 9470815-2 1997 To examine this, a mutant p53-expressing human endometrial adenocarcinoma cell line of the oestradiol-inhibited growth phenotype was treated with oestradiol for 2 weeks (short-term) and 6 months (long-term). Estradiol 91-101 P53 Homo sapiens 26-29 9470815-2 1997 To examine this, a mutant p53-expressing human endometrial adenocarcinoma cell line of the oestradiol-inhibited growth phenotype was treated with oestradiol for 2 weeks (short-term) and 6 months (long-term). Estradiol 146-156 P53 Homo sapiens 26-29 9470815-10 1997 Our results suggest the existence of a p53-independent pathway of oestradiol regulation of growth and proliferation in this human endometrial adenocarcinoma, resulting in accumulation of cells in G0/G1 through p21WAF1/Cip1 induction and, after prolonged treatment, downregulation of bcl-2 protein. Estradiol 66-76 P53 Homo sapiens 39-42 21528311-0 1997 Rapamycin-induced apoptosis is p53-independent in human prostate carcinoma PC-3 cells. Sirolimus 0-9 P53 Homo sapiens 31-34 9368590-1 1997 We investigated the expression of p53 in 82 formalin-fixed, paraffin-embedded archival tissue specimens of lip and intraoral squamous cell carcinomas (SCCs) from the period 1930-1995, by immunohistochemistry using three monoclonal antibodies (MAbs DO-7, DO-1 and 1801). Paraffin 60-68 P53 Homo sapiens 34-37 9363941-2 1997 Here we show that phosphorylation of human p53 at serine 15 occurs after DNA damage and that this leads to reduced interaction of p53 with its negative regulator, the oncoprotein MDM2, in vivo and in vitro. Serine 50-56 P53 Homo sapiens 43-46 9363941-2 1997 Here we show that phosphorylation of human p53 at serine 15 occurs after DNA damage and that this leads to reduced interaction of p53 with its negative regulator, the oncoprotein MDM2, in vivo and in vitro. Serine 50-56 P53 Homo sapiens 130-133 9363941-3 1997 Furthermore, using purified DNA-dependent protein kinase (DNA-PK), we demonstrate that phosphorylation of p53 at serines 15 and 37 impairs the ability of MDM2 to inhibit p53-dependent transactivation. Serine 113-120 P53 Homo sapiens 106-109 9363941-3 1997 Furthermore, using purified DNA-dependent protein kinase (DNA-PK), we demonstrate that phosphorylation of p53 at serines 15 and 37 impairs the ability of MDM2 to inhibit p53-dependent transactivation. Serine 113-120 P53 Homo sapiens 170-173 9332764-2 1997 We used a case-case analysis, comparing tumors with and without overexpression of the p53 gene product to evaluate the association of putative p53 mutations with tamoxifen use and other risk factors for endometrial cancer. Tamoxifen 162-171 P53 Homo sapiens 143-146 9332764-5 1997 There was a small association between p53 overexpression and treatment with tamoxifen for breast cancer (OR = 2.6; 95% CI, 0.69-9.8). Tamoxifen 76-85 P53 Homo sapiens 38-41 9332764-8 1997 The results suggest that use of tamoxifen may be associated with an increase in tumors that overexpress p53, although the results could be due to chance. Tamoxifen 32-41 P53 Homo sapiens 104-107 9312058-7 1997 In vivo generation of a C-terminal cleavage product of endogenous p53 similar in size to p50(DeltaC) correlated with up-regulation of p21 expression in ML-1 cells exposed to either adriamycin or cisplatin. Doxorubicin 181-191 P53 Homo sapiens 66-69 9312058-7 1997 In vivo generation of a C-terminal cleavage product of endogenous p53 similar in size to p50(DeltaC) correlated with up-regulation of p21 expression in ML-1 cells exposed to either adriamycin or cisplatin. Cisplatin 195-204 P53 Homo sapiens 66-69 9315628-10 1997 The data reported here indicate that intracellular levels and redox activity of copper are critical for p53 protein conformation and DNA-binding activity and suggest that copper ions may participate in the physiological control of p53 function. Copper 80-86 P53 Homo sapiens 104-107 9315628-10 1997 The data reported here indicate that intracellular levels and redox activity of copper are critical for p53 protein conformation and DNA-binding activity and suggest that copper ions may participate in the physiological control of p53 function. Copper 80-86 P53 Homo sapiens 231-234 9315628-0 1997 Regulation of p53 by metal ions and by antioxidants: dithiocarbamate down-regulates p53 DNA-binding activity by increasing the intracellular level of copper. Metals 21-26 P53 Homo sapiens 14-17 9315628-0 1997 Regulation of p53 by metal ions and by antioxidants: dithiocarbamate down-regulates p53 DNA-binding activity by increasing the intracellular level of copper. Copper 150-156 P53 Homo sapiens 14-17 9315628-10 1997 The data reported here indicate that intracellular levels and redox activity of copper are critical for p53 protein conformation and DNA-binding activity and suggest that copper ions may participate in the physiological control of p53 function. Copper 171-177 P53 Homo sapiens 104-107 9315628-10 1997 The data reported here indicate that intracellular levels and redox activity of copper are critical for p53 protein conformation and DNA-binding activity and suggest that copper ions may participate in the physiological control of p53 function. Copper 171-177 P53 Homo sapiens 231-234 9290950-4 1997 The expression of p53 was determined by immunohistochemistry in 19 pheochromocytomas and in 17 MTCs using two antibodies (D01 and D07) on frozen and paraffin-embedded tissues. Paraffin 149-157 P53 Homo sapiens 18-21 9275165-7 1997 Using this approach it has been possible to simplify the production of site-specifically modified oligonucleotides containing AFB1 adducts in the sequence context of a p53 mutational hotspot. Oligonucleotides 98-114 P53 Homo sapiens 168-171 9421067-13 1997 The single strong and diffuse p53 immunopositive tumor was negative for WAF-1 and was shown to contain a missense p53 point mutation (exon 7-codon 248 tryptophan). Tryptophan 151-161 P53 Homo sapiens 30-33 9421067-13 1997 The single strong and diffuse p53 immunopositive tumor was negative for WAF-1 and was shown to contain a missense p53 point mutation (exon 7-codon 248 tryptophan). Tryptophan 151-161 P53 Homo sapiens 114-117 9305847-7 1997 These observations stimulated additional biochemical and pharmacological experiments suggesting that p53 results in apoptosis through a three-step process: (1) the transcriptional induction of redox-related genes; (2) the formation of reactive oxygen species; and (3) the oxidative degradation of mitochondrial components, culminating in cell death. Reactive Oxygen Species 235-258 P53 Homo sapiens 101-104 9294607-0 1997 Ethanol upregulates the expression of p21 WAF1/CIP1 and prolongs G1 transition via a p53-independent pathway in human epithelial cells. Ethanol 0-7 P53 Homo sapiens 85-88 9294607-6 1997 The results also indicate that, at these non-cytotoxic concentrations, ethanol exhibits its effects through a p53-independent mechanism. Ethanol 71-78 P53 Homo sapiens 110-113 9413185-6 1997 The results suggested that in Panc-1 cells cisplatin and VP-16 induced apoptotic cell death which was mediated through the interaction of Bax expression in the presence of mutated p53. Cisplatin 43-52 P53 Homo sapiens 180-183 9436034-6 1997 ATRA also arrested the cell cycle in G1 and reduced the percentage of the S phase cell in terms of wild type p53, leading to apoptosis in part. Tretinoin 0-4 P53 Homo sapiens 109-112 10325638-1 1997 To explore the carcinogenic effect of asbestos at molecular level, we directly analyzed the mutations of exon 5, 7 and 8 of anti-oncogene p53 in paraffin-embedded human lung tissue affected by asbestos for the first time. Paraffin 145-153 P53 Homo sapiens 138-141 9446323-5 1997 The p53 Arg/Pro polymorphism study revealed the elevated frequency of Arg allele in lung and stomach cancer groups. Arginine 8-11 P53 Homo sapiens 4-7 10920912-2 1997 METHODS: Levels of c-erbB-2 and p53 protein were detected by immunohistochemistry in 184 paraffin-embeded blocks. Paraffin 89-97 P53 Homo sapiens 32-35 9446323-5 1997 The p53 Arg/Pro polymorphism study revealed the elevated frequency of Arg allele in lung and stomach cancer groups. Arginine 70-73 P53 Homo sapiens 4-7 9266962-6 1997 Because MG-132 and lactacycstin are highly specific inhibitors of the proteasome protease, our results suggest that the proteasome influences post-translational processes involved in proper folding and cytoplasmic clearing of E2F-1 and p53. lactacycstin 19-31 P53 Homo sapiens 236-239 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair. Cisplatin 107-116 P53 Homo sapiens 58-61 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair. Cisplatin 107-116 P53 Homo sapiens 161-164 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair. Cisplatin 107-116 P53 Homo sapiens 161-164 9269997-0 1997 Nitric oxide induces conformational and functional modifications of wild-type p53 tumor suppressor protein. Nitric Oxide 0-12 P53 Homo sapiens 78-81 9254608-0 1997 Phosphorylation of serine 392 stabilizes the tetramer formation of tumor suppressor protein p53. Serine 19-25 P53 Homo sapiens 92-95 9285694-5 1997 Comparatively, a treatment of the cells with 100 nM 4OH-tamoxifen (OHT) decreased cell number to 40% of the control without a concomitant decrease in the p53 levels suggesting a differential ability of these antiestrogens to regulate p53 levels in cells cultured in whole serum. Tamoxifen 67-70 P53 Homo sapiens 154-157 9285694-5 1997 Comparatively, a treatment of the cells with 100 nM 4OH-tamoxifen (OHT) decreased cell number to 40% of the control without a concomitant decrease in the p53 levels suggesting a differential ability of these antiestrogens to regulate p53 levels in cells cultured in whole serum. Tamoxifen 67-70 P53 Homo sapiens 234-237 9285694-6 1997 When cells were cultured in medium containing serum depleted of endogenous steroids (charcoal stripped serum), cell number and p53 levels declined. Steroids 75-83 P53 Homo sapiens 127-130 9293894-9 1997 TMC revealed the highest incidence of intense p53 positivity, and the highest mean MIB-1 index, and absence of the apoptosis-inhibitor protein bcl-2. tmc 0-3 P53 Homo sapiens 46-49 9299183-4 1997 In the colon, the "toxicology" of 5 fluorouracil (5FU) is entirely dependent on p53, since p53 knockouts lose the pathology of 5FU damage. Fluorouracil 36-48 P53 Homo sapiens 80-83 9299183-4 1997 In the colon, the "toxicology" of 5 fluorouracil (5FU) is entirely dependent on p53, since p53 knockouts lose the pathology of 5FU damage. Fluorouracil 36-48 P53 Homo sapiens 91-94 9242502-6 1997 Down-regulation of p53 with an anti-sense oligonucleotide did not affect apoptosis in glass-plated keratinocytes but effectively suppressed apoptosis in keratinocytes adhering via beta1 integrin. Oligonucleotides 42-57 P53 Homo sapiens 19-22 9263993-0 1997 Nitric oxide and superoxide induced p53 and Bax accumulation during mesangial cell apoptosis. Nitric Oxide 0-12 P53 Homo sapiens 36-39 9263993-0 1997 Nitric oxide and superoxide induced p53 and Bax accumulation during mesangial cell apoptosis. Superoxides 17-27 P53 Homo sapiens 36-39 9257692-0 1997 Active oxygen species mediate the solar ultraviolet radiation-dependent increase in the tumour suppressor protein p53 in human skin fibroblasts. Oxygen 7-13 P53 Homo sapiens 114-117 11596302-1 1997 Recent studies indicate that wild-type p53 can trigger cell apoptosis induced by many chemotherapeutic agents which induce DNA damage or cause disruptions of DNA metabolism, such as ADM, 5-FU, VP-16 and radiation. Fluorouracil 187-191 P53 Homo sapiens 39-42 9257692-4 1997 Here I show that p53 in cultured human skin fibroblasts is elevated after treatment with hydrogen peroxide, an oxidant produced in cells during exposure to solar UV radiation. Hydrogen Peroxide 89-106 P53 Homo sapiens 17-20 9257692-5 1997 Simulated solar UV radiation increased p53, and agents that scavenge active oxygen species, N-acetylcysteine, ascorbate and alpha-tocopherol, inhibited the increase. Oxygen 76-82 P53 Homo sapiens 39-42 9214306-3 1997 Fluorescence energy transfer between the tryptophans as well as quenching by their local structural environments complicates the analysis of the contributions of the individual tryptophans to the fluorescence of the wt protein, but it is demonstrated that Trp53, which is completely buried within the hydrophobic core, makes the dominant contribution to the fluorescence, while the fluorescence of Trp38 is largely quenched in the fully folded protein. Tryptophan 41-52 P53 Homo sapiens 256-261 9257692-5 1997 Simulated solar UV radiation increased p53, and agents that scavenge active oxygen species, N-acetylcysteine, ascorbate and alpha-tocopherol, inhibited the increase. Acetylcysteine 92-108 P53 Homo sapiens 39-42 9233778-3 1997 Stable Hep 3B cell lines were generated in which inducible p53 was introduced using either a temperature-sensitive mutant (p53val135) or a tamoxifen-regulated p53-estrogen receptor chimera (p53-mERtm-pBabepuro). Tamoxifen 139-148 P53 Homo sapiens 59-62 9212237-7 1997 At the same time, we found strong induction of p53, waf-1 and bax protein levels after CDDP treatment in the A2780, but not in the A2780-DX3, cell line. Cisplatin 87-91 P53 Homo sapiens 47-50 9212237-10 1997 A significant proportion of p53 in A2780-DX3 cells was found in the cytoplasmic compartment, and CDDP treatment induced a functional p53 protein in the nucleus of A2780 much more strongly than in A2780-DX3, which coincides with an increase of transcriptional activity of p53 in treated A2780 cells. Cisplatin 97-101 P53 Homo sapiens 133-136 9212237-10 1997 A significant proportion of p53 in A2780-DX3 cells was found in the cytoplasmic compartment, and CDDP treatment induced a functional p53 protein in the nucleus of A2780 much more strongly than in A2780-DX3, which coincides with an increase of transcriptional activity of p53 in treated A2780 cells. Cisplatin 97-101 P53 Homo sapiens 133-136 9212237-11 1997 We propose that the cross-resistance to CDDP in the A2780-DX3 cell line may be due to inactivation of a CDDP-dependent p53-accumulation pathway. Cisplatin 40-44 P53 Homo sapiens 119-122 9214672-7 1997 Mutation of the p53 gene was indicated by overexpression of p53 protein (i.e., cellular accumulation of mutant p53 protein) in paraffin-embedded ovarian cancer tissue blocks; the mutant protein was detected by means of standard immunohistochemical techniques. Paraffin 127-135 P53 Homo sapiens 16-19 9214672-7 1997 Mutation of the p53 gene was indicated by overexpression of p53 protein (i.e., cellular accumulation of mutant p53 protein) in paraffin-embedded ovarian cancer tissue blocks; the mutant protein was detected by means of standard immunohistochemical techniques. Paraffin 127-135 P53 Homo sapiens 60-63 9214672-7 1997 Mutation of the p53 gene was indicated by overexpression of p53 protein (i.e., cellular accumulation of mutant p53 protein) in paraffin-embedded ovarian cancer tissue blocks; the mutant protein was detected by means of standard immunohistochemical techniques. Paraffin 127-135 P53 Homo sapiens 60-63 9212237-11 1997 We propose that the cross-resistance to CDDP in the A2780-DX3 cell line may be due to inactivation of a CDDP-dependent p53-accumulation pathway. Cisplatin 104-108 P53 Homo sapiens 119-122 9301456-1 1997 This short report describes the detection of mutations of the TP53 tumour suppressor gene in sporadic ovarian carcinomas using archival paraffin-embedded tissues and automated fluorescent DNA sequencing. Paraffin 136-144 P53 Homo sapiens 62-66 9253509-2 1997 Codon 72 of the p53 gene is highly polymorphic with a reported arginine/proline allelotype frequency of 0.65/0.35 for Caucasians and a reversal of this ratio in African-Americans. Arginine 63-71 P53 Homo sapiens 16-19 9236923-7 1997 METHODS: Expression of p53 and PCNA were detected by immunocytochemistry in paraffin-embedded sections of infiltrating duct carcinoma and control breast tissue (normal tissue and adenoma). Paraffin 76-84 P53 Homo sapiens 23-26 9226370-5 1997 The Mdmx protein, which, based on SDS-PAGE, has a MW of 80 kDa, can bind p53 in vitro. Sodium Dodecyl Sulfate 34-37 P53 Homo sapiens 73-76 9234928-3 1997 We examined the growth effects of oligonucleotides designed to interfere with p53 expression and/or activity in p53-mutant/overexpressing endometrial cancer cell lines. Oligonucleotides 34-50 P53 Homo sapiens 78-81 9234928-3 1997 We examined the growth effects of oligonucleotides designed to interfere with p53 expression and/or activity in p53-mutant/overexpressing endometrial cancer cell lines. Oligonucleotides 34-50 P53 Homo sapiens 112-115 9215525-6 1997 Despite Dox ability to activate the DNA-damage dependent p53/p21 pathway, when induced in the absence of MyoD or other MRFs, p21 fails to maintain the postmitotic state in Dox-treated myocytes induced to differentiate. Doxorubicin 8-11 P53 Homo sapiens 57-60 9246643-3 1997 This region is phosphorylated at several evolutionarily conserved serines, suggesting that phosphorylation may be an important regulator of p53 function. Serine 66-73 P53 Homo sapiens 140-143 9246643-4 1997 In order to determine the effect of phosphorylation on tetramer formation, we synthesized phosphopeptides corresponding to p53(Ser303-Asp393) with phosphate incorporated at Ser315, Ser378, or Ser392, and at both Ser315 and Ser392. Phosphates 147-156 P53 Homo sapiens 123-126 9256014-4 1997 The primers used were oligonucleotides corresponding to the sequence of exon 5 on p53. Oligonucleotides 22-38 P53 Homo sapiens 82-85 21590120-2 1997 Pentoxifylline has recently been shown to sensitize breast cancer cells in which the wild-type p53 function was abrogated to cisplatin-induced apoptosis. Cisplatin 125-134 P53 Homo sapiens 95-98 9216855-4 1997 To assess the relationship between the LOH status of the p53 gene in the liver cirrhosis stage and that in HCC, we analyzed the samples microdissected from paraffin-embedded tissues using the polymerase-chain-reaction-based assay. Paraffin 156-164 P53 Homo sapiens 57-60 9192825-11 1997 Treatment of cells with 5-FU increased p53 protein levels, whereas sulindac metabolites did not induce expression. Fluorouracil 24-28 P53 Homo sapiens 39-42 9772449-2 1997 METHODS: p53 gene mutations were detected by a-32P-dCTP labelled radiative PCR-SSCP and the biochemical analyses of lipids in serum and AS tissues. 2'-deoxycytidine 5'-triphosphate 51-55 P53 Homo sapiens 9-12 9812577-0 1997 [Detection of p53 gene mutation in paraffin-embedded asbestos-related lung cancer tissue]. Paraffin 35-43 P53 Homo sapiens 14-17 9812585-1 1997 Expression of P53 protein was determined in the process and the end of induction of malignant transformation in human fetal lung cells, with organic extract from tap water in a river of City G, to study its molecular mechanism.

Paraffin 100-108 P53 Homo sapiens 75-78 9248088-4 1997 More recently, the prognostic role of biological parameters such as p53 gene or enzymes implicated in 5-fluorouracil metabolisms has been identified. Fluorouracil 102-116 P53 Homo sapiens 68-71 9178766-4 1997 Full length p53, but also a peptide representing a C-terminal fragment of the tumor suppressor gene product p53 (amino acids 264-393 which also harbors the CK2beta interaction site at amino acids 287-340) mimicked the polylysine effect in all respects, ie. Polylysine 218-228 P53 Homo sapiens 12-15 9185695-3 1997 We analyzed p53 mutations on paraffin-embedded specimens from 33 patients with AS by polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) followed by direct sequencing. Paraffin 29-37 P53 Homo sapiens 12-15 9178766-4 1997 Full length p53, but also a peptide representing a C-terminal fragment of the tumor suppressor gene product p53 (amino acids 264-393 which also harbors the CK2beta interaction site at amino acids 287-340) mimicked the polylysine effect in all respects, ie. Polylysine 218-228 P53 Homo sapiens 108-111 9178766-0 1997 The carboxy terminus of p53 mimics the polylysine effect of protein kinase CK2-catalyzed MDM2 phosphorylation. Polylysine 39-49 P53 Homo sapiens 24-27 9215611-9 1997 Curcumin-induced cell death was neither due to apoptosis nor to any significant change in the expression of apoptosis-related genes, including Bcl-2, p53, cyclin B and transglutaminase. Curcumin 0-8 P53 Homo sapiens 150-153 9189093-4 1997 METHODS: Expression of p53 protein was assayed in ten benign melanocytic naevi (BMN) and 50 surgically excised ethanol-fixed melanomas. Ethanol 111-118 P53 Homo sapiens 23-26 9179065-7 1997 p53 immunostaining was performed on paraffin embedded tissue. Paraffin 36-44 P53 Homo sapiens 0-3 9815771-4 1997 In IGROV-1/Pt1 cells, cisplatin resistance has been ascribed to a reduced susceptibility to apoptosis as a consequence of p53 mutation and inactivation of its function. Cisplatin 22-31 P53 Homo sapiens 122-125 9815771-5 1997 In the A2780 cisplatin-resistant subline, which retained the wild-type p53 gene status, the development of resistance has been possibly related to increased cell ability to repair drug-induced DNA damage. Cisplatin 13-22 P53 Homo sapiens 71-74 9205870-0 1997 Detectability of retinoblastoma (Rb) gene product and p53 antigen expression decreases in stored paraffin sections. Paraffin 97-105 P53 Homo sapiens 54-57 9264325-5 1997 Transcription from a p53 binding response element was inhibited in MM96L by a 24 hr ABHA treatment but enhanced in HeLa. azelaic bishydroxamic acid 84-88 P53 Homo sapiens 21-24 9186003-3 1997 Cisplatin-treated cells arrest in the G1 phase of the cell cycle, most likely due to a signal generated by the stabilization of p53 and the subsequent induction of p21WAF-1/Cip1. Cisplatin 0-9 P53 Homo sapiens 128-131 9187098-5 1997 Among p53 mutations at various sites, mutation at codon 242 (C TGC --> C CGC; Cys --> Arg) was specifically observed in both skin cancers and actinic keratoses. Cysteine 81-84 P53 Homo sapiens 6-9 9187098-5 1997 Among p53 mutations at various sites, mutation at codon 242 (C TGC --> C CGC; Cys --> Arg) was specifically observed in both skin cancers and actinic keratoses. Arginine 92-95 P53 Homo sapiens 6-9 11324502-0 1997 p53 independent G1 arrest and apoptosis induced by adriamycin. Doxorubicin 51-61 P53 Homo sapiens 0-3 11324502-2 1997 In MCF-7 cells that harbor wild-type p53, adriamycin-induced G1 arrest and apoptosis was accompanied by p53-independent regulation of WAF1/CIP1 as well as bax mRNA levels. Doxorubicin 42-52 P53 Homo sapiens 37-40 11324502-2 1997 In MCF-7 cells that harbor wild-type p53, adriamycin-induced G1 arrest and apoptosis was accompanied by p53-independent regulation of WAF1/CIP1 as well as bax mRNA levels. Doxorubicin 42-52 P53 Homo sapiens 104-107 11324502-3 1997 In MDA-MB-231 cells which possess a mutant p53, adriamycin-induced G1 arrest and apoptosis was also associated with a concomitant up-regulation of WAF1/CIP1 mRNA while these cells did not express bax or bcl-2 messages. Doxorubicin 48-58 P53 Homo sapiens 43-46 11324502-4 1997 Thus, adriamycin induces G1 arrest and apoptosis via a unique pathway which appears to involve activation of downstream effectors of p53-independent manner. Doxorubicin 6-16 P53 Homo sapiens 133-136 9191791-4 1997 However, the cytoprotective effects of DEX appeared to be more prominent in cell lines with wild-type p53 status (n = 2) than in p53 mutant cell lines (n = 3). Dexamethasone 39-42 P53 Homo sapiens 102-105 9213246-1 1997 The human hepatocellular carcinoma (HCC) cell line, HLF, expresses only mutant-type p53 (mt-p53), which has an amino acid substitution at the 244th residue from glycine to alanine. Glycine 161-168 P53 Homo sapiens 84-87 9213246-1 1997 The human hepatocellular carcinoma (HCC) cell line, HLF, expresses only mutant-type p53 (mt-p53), which has an amino acid substitution at the 244th residue from glycine to alanine. Glycine 161-168 P53 Homo sapiens 92-95 9213246-1 1997 The human hepatocellular carcinoma (HCC) cell line, HLF, expresses only mutant-type p53 (mt-p53), which has an amino acid substitution at the 244th residue from glycine to alanine. Alanine 172-179 P53 Homo sapiens 84-87 9213246-1 1997 The human hepatocellular carcinoma (HCC) cell line, HLF, expresses only mutant-type p53 (mt-p53), which has an amino acid substitution at the 244th residue from glycine to alanine. Alanine 172-179 P53 Homo sapiens 92-95 9154813-4 1997 Treatment of cytoplasmic extracts with RNase or puromycin in the presence of high salt, both of which are known to disrupt ribosomal function, dissociated p53 polypeptide from the ribosomes. Salts 82-86 P53 Homo sapiens 155-158 9154814-6 1997 We have directly tested for cooperativity between neu and mutant p53 in mammary tumorigenesis by creating bitransgenic mice carrying MMTV-neu and 172Arg-to-His p53 mutant (p53-172H). Histidine 156-159 P53 Homo sapiens 160-163 9154814-6 1997 We have directly tested for cooperativity between neu and mutant p53 in mammary tumorigenesis by creating bitransgenic mice carrying MMTV-neu and 172Arg-to-His p53 mutant (p53-172H). Histidine 156-159 P53 Homo sapiens 160-163 9174048-1 1997 We have previously shown that p53 disruption sensitizes certain cancer cell types to cisplatin (CDDP) (Fan et al., 1995). Cisplatin 85-94 P53 Homo sapiens 30-33 9149021-0 1997 Progesterone induces apoptosis and up-regulation of p53 expression in human ovarian carcinoma cell lines. Progesterone 0-12 P53 Homo sapiens 52-55 9174048-1 1997 We have previously shown that p53 disruption sensitizes certain cancer cell types to cisplatin (CDDP) (Fan et al., 1995). Cisplatin 96-100 P53 Homo sapiens 30-33 9174048-9 1997 Investigations into a possible cause of this enhanced sensitivity revealed that HCT-116 cells lacking p53 or p21 function exhibited a reduced ability to repair cisplatin-damaged CAT-reporter plasmids transfected into the cells. Cisplatin 160-169 P53 Homo sapiens 102-105 9158397-18 1997 Paucity of p53 mutations may be explained by the absence of exposure to tobacco smoke or alcohol. Alcohols 89-96 P53 Homo sapiens 11-14 9111352-8 1997 Conversely, activation of calpains by calcium ionophore led to a reduction of p53 in mammalian cells, and the effect was blocked by cell-permeant calpain inhibitors. Calcium 38-45 P53 Homo sapiens 78-81 9158397-17 1997 CONCLUSIONS: Our results suggest that p53 gene mutations are less frequent in squamous carcinomas occurring in nonsmoking young patients who do not drink alcohol than in young smokers or in the general population. Alcohols 154-161 P53 Homo sapiens 38-41 9206986-9 1997 This suggested that paclitaxel/RT would be a rational treatment approach for other malignancies with a high frequency of p53 mutations, such as gastric and pancreatic cancers. Paclitaxel 20-30 P53 Homo sapiens 121-124 9164202-1 1997 PURPOSE: To test the hypothesis that high bcl-2 expression and accumulation of p53 protein, both of which should inhibit apoptosis, are associated with a poorer tamoxifen response and a more aggressive clinical course in estrogen receptor (ER)-positive metastatic breast cancer. Tamoxifen 161-170 P53 Homo sapiens 79-82 9225073-0 1997 Modulation of p53, WAF1/p21 and BCL-2 expression during retinoic acid-induced differentiation of NB4 promyelocytic cells. Tretinoin 56-69 P53 Homo sapiens 14-17 21590081-0 1997 Induction of p53 protein by carbon-ion and proton beam irradiation in two close human lymphoblastoid cell lines with different p53 status. Carbon 28-34 P53 Homo sapiens 13-16 21590081-1 1997 In this study, we compared the kinetics of the postirradiation p53 protein expression for carbon ion beam (290 MeV/n, LET 75 keV/mu m) and proton beam (65 MeV) with that of (13)7Cs-gamma ray. Carbon 90-96 P53 Homo sapiens 63-66 9129144-5 1997 Positive staining of p53 protein was observed in three of the paraffin embedded tissues that were available: brain tumor, rhabdomyosarcoma, and lymphocytes from a normal lymph node from the rhabdomyosarcoma patient. Paraffin 62-70 P53 Homo sapiens 21-24 9108094-3 1997 Taxol (paclitaxel) is more effective in the presence of mutant p53. Paclitaxel 0-5 P53 Homo sapiens 63-66 9108094-3 1997 Taxol (paclitaxel) is more effective in the presence of mutant p53. Paclitaxel 7-17 P53 Homo sapiens 63-66 9108094-13 1997 The synergistic therapeutic effect of Taxol with (90)Y-ChL6 may relate to the p53 mutant status and BCL2 expression in HBT 3477 cells, observations that increase the likelihood that the results of this study are relevant to therapy for breast cancer in patients. Paclitaxel 38-43 P53 Homo sapiens 78-81 9083038-6 1997 We show that cross-linking of ICAM-1 on the B lymphoma line A20 induces an increase in tyrosine phosphorylation of several cellular proteins, including the Src family kinase p53/p56(lyn). Tyrosine 87-95 P53 Homo sapiens 174-177 9108075-1 1997 In the P53 tumor suppressor gene, a remarkably large number of somatic mutations are found at methylated CpG dinucleotides. cytidylyl-3'-5'-guanosine 105-122 P53 Homo sapiens 7-27 9108075-5 1997 To investigate other possible mechanisms underlying the selectivity of BPDE binding, we have mapped the adducts in plasmid DNA containing genomic P53 sequences. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 71-75 P53 Homo sapiens 146-149 9074626-0 1997 The induction of apoptosis in proliferating human fibroblasts by oxygen radicals is associated with a p53- and p21WAF1CIP1 induction. Reactive Oxygen Species 65-80 P53 Homo sapiens 102-105 9149846-0 1997 Antisense oligonucleotides to p53 tumor suppressor suppress the induction of apoptosis by epidermal growth factor in NCI-H 596 human lung cancer cells. Oligonucleotides 10-26 P53 Homo sapiens 30-33 9149846-5 1997 Results showed that EGF plus p53 sense oligonucleotides induced EGF-dependent and p53-dependent apoptosis in NCI-H 596 cells within 8 hours. Oligonucleotides 39-55 P53 Homo sapiens 29-32 9149846-5 1997 Results showed that EGF plus p53 sense oligonucleotides induced EGF-dependent and p53-dependent apoptosis in NCI-H 596 cells within 8 hours. Oligonucleotides 39-55 P53 Homo sapiens 82-85 9149846-6 1997 On the other hand, antisense gene therapy using antisense oligonucleotides to p53 tumor suppressor suppressed the induction of EGF-dependent and p53-dependent apoptosis. Oligonucleotides 58-74 P53 Homo sapiens 78-81 9149846-6 1997 On the other hand, antisense gene therapy using antisense oligonucleotides to p53 tumor suppressor suppressed the induction of EGF-dependent and p53-dependent apoptosis. Oligonucleotides 58-74 P53 Homo sapiens 145-148 9149846-7 1997 Mutated p53 antisense-containing mutated CG dinucleotides had the same effect as that of p53 antisense on suppression of apoptosis in NCI-H 596 cells. cytidylyl-3'-5'-guanosine 41-57 P53 Homo sapiens 8-11 9149846-8 1997 We found that a new nucleic acid drug, another mutated p53 antisense-containing mutation at three bases immediately 5" and 3" from the CG dinucleotides, potentiated the induction of apoptosis and failed to suppress the induction of EGF-dependent apoptosis. cytidylyl-3'-5'-guanosine 135-151 P53 Homo sapiens 55-58 9149846-9 1997 These results suggest that gene therapy using antisense oligonucleotides to the p53 tumor suppressor is effective on EGF-dependent apoptosis of NCI-H 596 human non-small cell lung cancer.

Dexamethasone 108-121 P53 Homo sapiens 67-70 9058378-7 1997 The p53-mediated repression of dexamethasone-induced sgkGRE activity required both the DNA binding and transactivation functions of the p53 protein. Dexamethasone 31-44 P53 Homo sapiens 4-7 9058378-7 1997 The p53-mediated repression of dexamethasone-induced sgkGRE activity required both the DNA binding and transactivation functions of the p53 protein.

Cysteine 138-146 P53 Homo sapiens 256-259 18726304-2 1997 It was confirmed that the mt-p53 cDNA contained the complete coding sequence of p53 gene but mutated at codon 245 (G-->T) and resulted in glycine to cysteine by sequencing analysis.

Cisplatin 77-86 P53 Homo sapiens 18-21 9010231-4 1997 As a preliminary study, we demonstrated in breast adenocarcinoma cell lines that the nuclear accumulation of the inhibitor of cyclin dependent kinase p21(WAFl/CIP1), in response to adriamycin treatment, specifically reflected the activity of a functional wild-type p53 protein. Doxorubicin 181-191 P53 Homo sapiens 265-268 9010220-1 1997 Loss of p53 function is associated with the acquisition of cisplatin resistance in the human ovarian adenocarcinoma A2780 cell line. Cisplatin 59-68 P53 Homo sapiens 8-11 9010220-7 1997 A synthetic peptide, representing the predicted amino acid sequence of this GSE, conferred resistance to cisplatin when introduced into A2780 cells and inhibited the sequence specific DNA binding activity of p53 protein in vitro.

Cisplatin 126-135 P53 Homo sapiens 54-57 9013707-8 1997 Overexpression of another p53-regulated gene, GADD45, by contrast, protected cells from cisplatin killing. Cisplatin 88-97 P53 Homo sapiens 26-29 9013707-9 1997 These findings suggest that different downstream effectors of the p53 pathway may exert different effects on cellular survival after treatment with cancer chemotherapy drugs such as cisplatin.

Paraffin 46-54 P53 Homo sapiens 4-7 9323493-0 1997 Changes in levels of expression of p53 and the product of the bcl-2 in lines of gastric cancer cells during cisplatin-induced apoptosis. Cisplatin 108-117 P53 Homo sapiens 35-38 9323493-2 1997 After incubation with cisplatin, apoptotic cells were detected more frequently among MKN-45 and MKN-74 cells with a wild-type gene for p53 and without expression of the bcl-2 protein than among HSC-39, MKN-28, and KATO-III cells with a mutation or complete deletion of the gene for p53 and with overexpression of the bcl-2 protein. Cisplatin 22-31 P53 Homo sapiens 135-138 9323493-2 1997 After incubation with cisplatin, apoptotic cells were detected more frequently among MKN-45 and MKN-74 cells with a wild-type gene for p53 and without expression of the bcl-2 protein than among HSC-39, MKN-28, and KATO-III cells with a mutation or complete deletion of the gene for p53 and with overexpression of the bcl-2 protein.

Doxorubicin 16-26 P53 Homo sapiens 105-108 14646556-3 1997 Here we studied Adriamycin (ADM)-induced apoptosis in four human bladder cancer cell lines in respect of p53, p21WAF1/CIP1 and Bcl-2 family proteins.

Fluorouracil 48-52 P53 Homo sapiens 126-129 14646558-4 1997 On the other hand, 50 microM 5-FU had little effect on the induction of apoptosis in MKN-74 cells, the value being approximately 2% after 72 h. Induction of P53 expression was noted 3 h after initiating the treatment, followed by the induction of P21/Waf1 after 6 h in both MKN-74 and MKN-45 cells. Fluorouracil 29-33 P53 Homo sapiens 157-160 14646558-8 1997 These results might indicate that (1) 1mM 5-FU induces apoptosis in cultured gastric cancer cells carrying the wild-type p53 gene, but not those carrying the mutated type or a gene deletion, and (2) the elevated Bax/Bcl-2 expression ratio plays a more crucial role than the higher expression of P21/Waf1 in the induction of p53- gene dependent apoptosis. Fluorouracil 42-46 P53 Homo sapiens 121-124 14646558-8 1997 These results might indicate that (1) 1mM 5-FU induces apoptosis in cultured gastric cancer cells carrying the wild-type p53 gene, but not those carrying the mutated type or a gene deletion, and (2) the elevated Bax/Bcl-2 expression ratio plays a more crucial role than the higher expression of P21/Waf1 in the induction of p53- gene dependent apoptosis. Fluorouracil 42-46 P53 Homo sapiens 324-327 9374378-4 1997 Drug resistance was associated with considerably enhanced expression of the p53 suppressor protein in HeLa-C3 cells after cisplatin exposure but seemed not to be regulated by the bcl-2-dependent pathway.

Cisplatin 186-195 P53 Homo sapiens 58-61 8942496-3 1996 STUDY DESIGN: Immunohistochemical evaluation was used to examine p53 expression in paraffin blocks from 179 endometrial adenocarcinomas. Paraffin 83-91 P53 Homo sapiens 65-68 9038605-4 1996 In 4 cases, the mutations lead to distinct changes in the primary or secondary structure of the protein (cysteine-->tyrosine, proline-->leucine) and were associated with marked accumulation of p53 protein. Cysteine 105-113 P53 Homo sapiens 199-202 9038605-4 1996 In 4 cases, the mutations lead to distinct changes in the primary or secondary structure of the protein (cysteine-->tyrosine, proline-->leucine) and were associated with marked accumulation of p53 protein. Tyrosine 119-127 P53 Homo sapiens 199-202 8918047-6 1996 seropositive IHAT (1/64) and low LTT (20 & 40%) gave positive P53 antibody and moderate (1) and marked (1) degrees Cathepsin D. Adenosine Monophosphate 42-45 P53 Homo sapiens 66-69 8989916-0 1996 Induction of HSP70 gene expression by modulation of Ca(+2) ion and cellular p53 protein by curcumin in colorectal carcinoma cells. Curcumin 91-99 P53 Homo sapiens 76-79 8989916-5 1996 The reduction of p53 gene expression was accompanied by the induction of HSP70 gene expression in the curcumin-treated cells. Curcumin 102-110 P53 Homo sapiens 17-20 8989916-6 1996 These findings suggest that curcumin may induce the expression of the HSP70 gene through the initial depletion of intracellular Ca(+2), followed by the suppression of p53 gene function in the target cells. Curcumin 28-36 P53 Homo sapiens 167-170 9182295-5 1996 Single strand conformation polymorphism analysis (SSCP-PCR) from DNA obtained by microdissection demonstrated the presence of a mutation (TAT-->TGT; Tyr-->Cys) in codon 220, exon six of the p53 gene in the anaplastic component, that was absent in the well-differentiated follicular areas. Tyrosine 152-155 P53 Homo sapiens 196-199 9182295-5 1996 Single strand conformation polymorphism analysis (SSCP-PCR) from DNA obtained by microdissection demonstrated the presence of a mutation (TAT-->TGT; Tyr-->Cys) in codon 220, exon six of the p53 gene in the anaplastic component, that was absent in the well-differentiated follicular areas. Cysteine 161-164 P53 Homo sapiens 196-199 8943066-0 1996 BAX enhances paclitaxel-induced apoptosis through a p53-independent pathway. Paclitaxel 13-23 P53 Homo sapiens 52-55 8955620-0 1996 Detection of p53 gene abnormality by sequence analysis of archival paraffin tissue. Paraffin 67-75 P53 Homo sapiens 13-16 21541641-4 1996 Increased p53 protein levels have previously been shown to correlate with disease progression in a series of colorectal carcinoma patients treated with 5-FU/folinic acid biomodulated chemotherapy. Fluorouracil 152-156 P53 Homo sapiens 10-13 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Alanine 188-195 P53 Homo sapiens 67-70 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Alanine 188-195 P53 Homo sapiens 157-160 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Cisplatin 246-255 P53 Homo sapiens 67-70 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Cisplatin 246-255 P53 Homo sapiens 157-160 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Doxorubicin 257-268 P53 Homo sapiens 67-70 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Doxorubicin 257-268 P53 Homo sapiens 157-160 8945622-4 1996 When exposed to DNA-damaging agents, cisplatin or mitomycin C, apoptosis was induced in RT4 with the wild-type (wt) p53/wt p21, whereas T24 with the p53 non-sense mutation/wt p21 was resistant. Cisplatin 37-46 P53 Homo sapiens 116-119 8945622-4 1996 When exposed to DNA-damaging agents, cisplatin or mitomycin C, apoptosis was induced in RT4 with the wild-type (wt) p53/wt p21, whereas T24 with the p53 non-sense mutation/wt p21 was resistant. Cisplatin 37-46 P53 Homo sapiens 149-152 8950204-4 1996 Northern blot analyses showed that p53 and p21Waf1/Cip1 mRNA were detectable in all untreated cells, and increasing amounts of these transcripts were identified in all cell lines treated with cisplatin. Cisplatin 192-201 P53 Homo sapiens 35-38 8950204-7 1996 Our results show that there were differences in sensitivity to cisplatin among four types of high risk HPV-positive cells, possibly due to different levels of p21Waf1/Cip1 up-regulation by functional p53. Cisplatin 63-72 P53 Homo sapiens 200-203 8942499-3 1996 Overexpression of p53 protein was determined with the use of immunohistochemistry on fixed and paraffin-embedded tissue. Paraffin 95-103 P53 Homo sapiens 18-21 9042268-3 1996 The cytotoxic effects of DNA-crosslinking chemotherapeutica such as cisplatin could be enhanced by mutated p53 which is no longer able to repair drug-induced DNA damage. Cisplatin 68-77 P53 Homo sapiens 107-110 9042268-4 1996 In contrast, DNA synthesis blockers such as fluorouracil can induce apoptosis through p53-dependent mechanisms. Fluorouracil 44-56 P53 Homo sapiens 86-89 9042215-4 1996 Among the 21 patients with stage III-IV disease, a complete clinical response to front-line platinum-based chemotherapy was obtained by 46.2% of the 13 patients without anti-p53 antibodies and 25.0% of the 8 patients with anti-p53 antibodies. Platinum 92-100 P53 Homo sapiens 174-177 8895764-3 1996 In this report, we describe the mechanism by which the retinoid 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid (CD437) induces p21WAF1/CIP1 in breast carcinoma cells possessing either a wild-type (MCF-7 cells) or mutated (MDA-MB-468 cells) p53. CD 437 64-129 P53 Homo sapiens 259-262 9042215-4 1996 Among the 21 patients with stage III-IV disease, a complete clinical response to front-line platinum-based chemotherapy was obtained by 46.2% of the 13 patients without anti-p53 antibodies and 25.0% of the 8 patients with anti-p53 antibodies. Platinum 92-100 P53 Homo sapiens 227-230 9042218-3 1996 The regulatory and controlling influence of Tamoxifen on numerous genes involved in apoptosis (p53, Bcl 2, c-myc, erb-B2 and others) will be discussed in this review. Tamoxifen 44-53 P53 Homo sapiens 95-98 8895764-10 1996 Thus, CD437 is a novel retinoid which enhances p21WAF1/CIP1 mRNA levels through stabilization of the message regardless of the p53 status of the cell. CD 437 6-11 P53 Homo sapiens 127-130 8895764-3 1996 In this report, we describe the mechanism by which the retinoid 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid (CD437) induces p21WAF1/CIP1 in breast carcinoma cells possessing either a wild-type (MCF-7 cells) or mutated (MDA-MB-468 cells) p53. CD 437 131-136 P53 Homo sapiens 259-262 8903408-5 1996 Introduction of WT-p53 into AFP-positive HCC cells by retroviral infection markedly inhibited their clonal growth in monolayer and soft agar cultures, and increased the sensitivity of these cells to the chemotherapeutic drug, cisplatin. Cisplatin 226-235 P53 Homo sapiens 19-22 8960021-8 1996 The association we found between alcohol intake and mutant p53 expression may deserve further investigation. Alcohols 33-40 P53 Homo sapiens 59-62 8875976-4 1996 Three peaks of p53NK activity were observed following fractionation of HeLa cell lysates; these activities were each able to catalyse phosphorylation of up to three residues (serines 4, 6 and 9 in murine p53) within the N-terminus of the p53 protein. Serine 175-182 P53 Homo sapiens 15-18 8956076-4 1996 The C-terminal segment p53(361-393) (3) and its derivative phosphorylated at serine 392 (3P392) were synthesized as partially protected peptides in the solid phase using Fmoc chemistry. Serine 77-83 P53 Homo sapiens 23-26 8956076-5 1996 Phosphoamino acid was incorporated into the N-terminal segment (1P315) at the residue corresponding to p53 serine 315 as Boc-Ser(PO3(Bzl)2)-OH during synthesis. Serine 107-113 P53 Homo sapiens 103-106 8956076-7 1996 A derivative phosphorylated at serine 378 was synthesized in a one-step condensation of the unphosphorylated N-terminal segment (1) and the phosphorylated long C-terminal segment p53(335-393) (2-3P378). Serine 31-37 P53 Homo sapiens 179-182 8911337-1 1996 A more effective gene therapy strategy for lung cancer using sequential cisplatin administration and adenovirus-mediated p53 gene transfer was developed on the basis of our previous observation of enhanced expression of a reporter gene in malignant cells exposed to cisplatin before gene transfer. Cisplatin 266-275 P53 Homo sapiens 121-124 8911337-2 1996 Transfer of the normal (wildtype) p53 gene into cisplatin-treated H1299 cells, in which p53 is homozygously deleted, resulted in up to a 60% further inhibition of cell proliferation in vitro than p53 transfer into untreated H1299 cells. Cisplatin 48-57 P53 Homo sapiens 34-37 8911337-2 1996 Transfer of the normal (wildtype) p53 gene into cisplatin-treated H1299 cells, in which p53 is homozygously deleted, resulted in up to a 60% further inhibition of cell proliferation in vitro than p53 transfer into untreated H1299 cells. Cisplatin 48-57 P53 Homo sapiens 88-91 8911337-2 1996 Transfer of the normal (wildtype) p53 gene into cisplatin-treated H1299 cells, in which p53 is homozygously deleted, resulted in up to a 60% further inhibition of cell proliferation in vitro than p53 transfer into untreated H1299 cells. Cisplatin 48-57 P53 Homo sapiens 88-91 8911337-3 1996 The cisplatin plus p53 gene transfer strategy yielded significantly greater apoptosis and tumor growth suppression in an animal model of subcutaneous H1299 tumor nodules than wildtype p53 gene transfer alone. Cisplatin 4-13 P53 Homo sapiens 184-187 8911337-4 1996 The timing of cisplatin administration and p53 gene transfer was shown to be critical: cisplatin administration simultaneous with or subsequent to p53 gene transfer was less effective than cisplatin-first sequential treatment. Cisplatin 14-23 P53 Homo sapiens 147-150 8911337-4 1996 The timing of cisplatin administration and p53 gene transfer was shown to be critical: cisplatin administration simultaneous with or subsequent to p53 gene transfer was less effective than cisplatin-first sequential treatment. Cisplatin 87-96 P53 Homo sapiens 43-46 8911337-4 1996 The timing of cisplatin administration and p53 gene transfer was shown to be critical: cisplatin administration simultaneous with or subsequent to p53 gene transfer was less effective than cisplatin-first sequential treatment. Cisplatin 87-96 P53 Homo sapiens 43-46 8876226-0 1996 Reactive oxygen species are downstream mediators of p53-dependent apoptosis. Reactive Oxygen Species 0-23 P53 Homo sapiens 52-55 8876226-3 1996 We sought to determine whether a central modulator of apoptosis, p53, regulates the levels of intracellular ROS and whether a rise in ROS levels is required for the induction of p53-dependent apoptosis. Reactive Oxygen Species 108-111 P53 Homo sapiens 65-68 8876226-3 1996 We sought to determine whether a central modulator of apoptosis, p53, regulates the levels of intracellular ROS and whether a rise in ROS levels is required for the induction of p53-dependent apoptosis. Reactive Oxygen Species 134-137 P53 Homo sapiens 178-181 8876226-5 1996 Cells sensitive to p53-mediated apoptosis produced ROS concomitantly with p53 overexpression, whereas cells resistant to p53 failed to produce ROS. Reactive Oxygen Species 51-54 P53 Homo sapiens 19-22 8876226-7 1996 These results suggest that p53 acts to regulate the intracellular redox state and induces apoptosis by a pathway that is dependent on ROS production. Reactive Oxygen Species 134-137 P53 Homo sapiens 27-30 8832894-2 1996 The distribution of benzo[a]pyrene diol epoxide (BPDE) adducts along exons of the P53 gene in BPDE-treated HeLa cells and bronchial epithelial cells was mapped at nucleotide resolution. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 20-47 P53 Homo sapiens 82-85 8832894-2 1996 The distribution of benzo[a]pyrene diol epoxide (BPDE) adducts along exons of the P53 gene in BPDE-treated HeLa cells and bronchial epithelial cells was mapped at nucleotide resolution. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 49-53 P53 Homo sapiens 82-85 8832894-2 1996 The distribution of benzo[a]pyrene diol epoxide (BPDE) adducts along exons of the P53 gene in BPDE-treated HeLa cells and bronchial epithelial cells was mapped at nucleotide resolution. 7,8-Dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide 94-98 P53 Homo sapiens 82-85 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Alanine 130-133 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Arginine 135-138 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Histidine 150-153 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Arginine 155-158 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Tryptophan 170-173 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Arginine 155-158 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Serine 190-193 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Arginine 155-158 P53 Homo sapiens 101-104 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Histidine 214-217 P53 Homo sapiens 101-104 8892753-3 1996 In contrast, the gadd gene stress response to base-damaging agents, such as methylmethane sulfonate (MMS) or UV radiation, or medium depletion (starvation) occurs in all mammalian cells examined to date regardless of p53 status for both GADD45 and also GADD153, which is not IR-responsive in many lines with functional p53. gadd 17-21 P53 Homo sapiens 319-322 8870682-0 1996 Nitric oxide-induced apoptosis: p53-dependent and p53-independent signalling pathways. Nitric Oxide 0-12 P53 Homo sapiens 32-35 8870682-0 1996 Nitric oxide-induced apoptosis: p53-dependent and p53-independent signalling pathways. Nitric Oxide 0-12 P53 Homo sapiens 50-53 8870682-4 1996 With the use of S-nitroglutathione (GSNO) we correlated a dose-dependent p53 up-regulation to DNA fragmentation measured after 4 h and 8 h, respectively. S-Nitrosoglutathione 36-40 P53 Homo sapiens 73-76 8870682-7 1996 Clones with down-regulated p53 levels in response to GSNO exhibited a marked reduction in DNA fragmentation. S-Nitrosoglutathione 53-57 P53 Homo sapiens 27-30 17180111-0 1996 Bile acid activation of the gadd153 promoter and of p53-independent apoptosis: relevance to colon cancer. Bile Acids and Salts 0-9 P53 Homo sapiens 52-55 17180111-5 1996 We also show that bile acid induction of apoptosis is p53-independent. Bile Acids and Salts 18-27 P53 Homo sapiens 54-57 9816112-6 1996 However, we find that the induction of wild-type p53 powerfully potentiates the cytotoxicity of both irradiation and 5-fluorouracil, two agents that are used clinically in the treatment of colorectal cancer. Fluorouracil 117-131 P53 Homo sapiens 49-52 8910043-6 1996 In invasive ductal adenocarcinoma of the pancrease (7 cases), ras, c-erbB-2, p53 and Rb gene products were expressed in 3/7 (43%), 6/7 (86%), 2/7 (29%) and 3/& (43%) cases respectively. Adenosine Monophosphate 159-162 P53 Homo sapiens 77-80 8931502-2 1996 METHOD: A dexamethazone-inducible wt-p53 cDNA was introduced into two cervical carcinoma cell lines (TMCC-1 and ME180) and morphological changes were examined under a phase contrast microscope and following Papanicolaou staining. Dexamethasone 10-23 P53 Homo sapiens 37-40 8931502-3 1996 RESULTS: TMCC-1 clones obtained by transfection with wt-p53 gene had an altered morphology especially after induction of p53 expression by treatment with dexamethazone. Dexamethasone 154-167 P53 Homo sapiens 56-59 8931502-3 1996 RESULTS: TMCC-1 clones obtained by transfection with wt-p53 gene had an altered morphology especially after induction of p53 expression by treatment with dexamethazone. Dexamethasone 154-167 P53 Homo sapiens 121-124 21541584-12 1996 The mean TPA percentage was significantly higher in the p53-positive tumors or tumor components (EC and YST) when compared with the mean TPA percentage in those neoplasms that were focally positive or negative for p53 protein (Ki-67, P=0.003; PCNA, P=0.046). Tetradecanoylphorbol Acetate 9-12 P53 Homo sapiens 56-59 21541584-13 1996 p53 expression was also associated with histologically aggressive tumors (ECs and YSTs) that also exhibit high TPA. Tetradecanoylphorbol Acetate 111-114 P53 Homo sapiens 0-3 8808919-3 1996 MATERIALS AND METHODS: The expression of p53 and bcl-2 was evaluated in archival paraffin-embedded RP specimens from 175 patients followed from 1 to 9 years (mean = 4.6 years) and correlated with stage, grade, race and serologic (PSA) recurrence following surgery. Paraffin 81-89 P53 Homo sapiens 41-44 8910896-0 1996 A nonsense mutation (Arg-196-Term) in exon 6 of the human TP53 gene identified in small cell lung carcinoma. Arginine 21-24 P53 Homo sapiens 58-62 8837616-5 1996 To determine whether tumor-derived p53 mutants are irreversibly inactivated, we introduced basic residues in their DNA binding domains, aiming to establish novel contacts between p53 and the DNA phosphate backbone. Phosphates 195-204 P53 Homo sapiens 35-38 8837616-5 1996 To determine whether tumor-derived p53 mutants are irreversibly inactivated, we introduced basic residues in their DNA binding domains, aiming to establish novel contacts between p53 and the DNA phosphate backbone. Phosphates 195-204 P53 Homo sapiens 179-182 8921985-12 1996 Recent studies have provided additional evidence that reactive oxygen species (ROS) and oxidative DNA damage may be involved in AFB1-induced p53 and ras mutations. Reactive Oxygen Species 54-77 P53 Homo sapiens 141-144 8808702-6 1996 In this study, we show that WAF1/CIP1 was induced in p53-dependent apoptosis of U87-MG glioma cells by cis-diamminedichloroplatinum (cisplatin), and overexpression of WAF1/CIP1 induced apoptosis in U87-MG cells without cisplatin treatment. Cisplatin 133-142 P53 Homo sapiens 53-56 8921985-12 1996 Recent studies have provided additional evidence that reactive oxygen species (ROS) and oxidative DNA damage may be involved in AFB1-induced p53 and ras mutations. Reactive Oxygen Species 79-82 P53 Homo sapiens 141-144 8895543-0 1996 Cisplatin-induced apoptosis and p53 gene status in a cisplatin-resistant human ovarian carcinoma cell line. Cisplatin 53-62 P53 Homo sapiens 32-35 8895543-16 1996 Therefore, the presence of non-functional p53 in resistant cells might be involved in the relative failure of cisplatin-induced apoptosis in these cells. Cisplatin 110-119 P53 Homo sapiens 42-45 8798554-9 1996 Exogenously added H2O2 increased p58(c-fgr) and p53/56(lyn) activities in nonadherent neutrophils. Hydrogen Peroxide 18-22 P53 Homo sapiens 48-51 8798554-11 1996 Tyrosine phosphorylation of proteins in adherent, CGD neutrophils was only partially inhibited, suggesting that the full activation of p58(c-fgr) and p53/56(lyn), which depends on endogenously produced ROI, does not represent an absolute requirement for protein tyrosine phosphorylation. Tyrosine 0-8 P53 Homo sapiens 150-153 8927716-8 1996 Phorbol 12-myristate 13-acetate (PMA) induced phosphorylation of p53 and pRb1O5 in MCF-7 cells, but EMF exposure had no effect. Tetradecanoylphorbol Acetate 0-31 P53 Homo sapiens 65-68 8927716-8 1996 Phorbol 12-myristate 13-acetate (PMA) induced phosphorylation of p53 and pRb1O5 in MCF-7 cells, but EMF exposure had no effect. Tetradecanoylphorbol Acetate 33-36 P53 Homo sapiens 65-68 8808702-0 1996 WAF1/CIP1 increases the susceptibility of p53 non-functional malignant glioma cells to cisplatin-induced apoptosis. Cisplatin 87-96 P53 Homo sapiens 42-45 8808702-6 1996 In this study, we show that WAF1/CIP1 was induced in p53-dependent apoptosis of U87-MG glioma cells by cis-diamminedichloroplatinum (cisplatin), and overexpression of WAF1/CIP1 induced apoptosis in U87-MG cells without cisplatin treatment. Cisplatin 103-131 P53 Homo sapiens 53-56 8808702-6 1996 In this study, we show that WAF1/CIP1 was induced in p53-dependent apoptosis of U87-MG glioma cells by cis-diamminedichloroplatinum (cisplatin), and overexpression of WAF1/CIP1 induced apoptosis in U87-MG cells without cisplatin treatment. Cisplatin 219-228 P53 Homo sapiens 53-56 8808702-7 1996 In contrast, the p53-independent apoptosis of GB-1 glioma cells by cisplatin did not express WAF1/CIP1. Cisplatin 67-76 P53 Homo sapiens 17-20 8836183-3 1996 We previously demonstrated that ssDNA oligonucleotides interact with the C-terminal domain of p53 and stimulate binding to internal segments of long ssDNA by the p53 core domain. Oligonucleotides 38-54 P53 Homo sapiens 94-97 8826941-3 1996 In vitro data and animal studies suggest that paclitaxel may have a unique ability to activate tumor cell apoptosis in the absence of wild-type p53 function. Paclitaxel 46-56 P53 Homo sapiens 144-147 8826941-4 1996 The authors sought to determine whether p53 mutations affect response to paclitaxel/RT in patients with locally advanced NSCLC. Paclitaxel 73-83 P53 Homo sapiens 40-43 8826941-13 1996 These results suggest that paclitaxel/RT may be an active regimen for patients with other locally advanced neoplasms with high rates of p53 gene mutations. Paclitaxel 27-37 P53 Homo sapiens 136-139 8836183-3 1996 We previously demonstrated that ssDNA oligonucleotides interact with the C-terminal domain of p53 and stimulate binding to internal segments of long ssDNA by the p53 core domain.

Cisplatin 205-214 P53 Homo sapiens 228-231 8896794-7 1996 The dehydrating (coagulant) fixatives (e.g., ethanol and methanol) preserved immunorecognition of p53 and broad spectrum keratins best while the slow cross-linking fixatives (e.g., unbuffered zinc formalin) were best for demonstrating TGF alpha and p185erbB-2. Ethanol 45-52 P53 Homo sapiens 98-101 8824527-12 1996 At this passage, mutation of the p53 gene was detected at codon 273 of exon 8, with G to T conversion (Arg to Leu). Arginine 103-106 P53 Homo sapiens 33-36 8841466-7 1996 Further separation of the patient-derived fats indicated that the amplification of p53 gene expression in HT-29 cells could be achieved primarily by addition of the diacylglycerides fraction. diacylglycerides 165-181 P53 Homo sapiens 83-86 8841466-8 1996 Addition of the purified fatty acids, comprising the diglyceride fraction, indicated that the fatty acids, 16:1, 18:0, and 18:1, induced the most significant increases in p53 expression by HT-29 cells. Fatty Acids 25-36 P53 Homo sapiens 171-174 8841466-8 1996 Addition of the purified fatty acids, comprising the diglyceride fraction, indicated that the fatty acids, 16:1, 18:0, and 18:1, induced the most significant increases in p53 expression by HT-29 cells. Fatty Acids 94-105 P53 Homo sapiens 171-174 8756655-1 1996 Human wild-type (wt) p53 can induce apoptosis in transiently transfected H1299 cells maintained at 37 degrees C, whereas tumor-derived mutant forms of p53 (with the mutation Ala-143, His-175, or Trp-248) fail to do so.

Alanine 40-43 P53 Homo sapiens 17-20 8683636-1 1996 BACKGROUND: We previously observed decreased p53 immunostaining over time in paraffin-embedded sections of ductal carcinoma in situ of the breast of women; these sections had been stored on slides at room temperature. Paraffin 77-85 P53 Homo sapiens 45-48 9387269-1 1996 Paraffin-embedded hepatocellular carcinoma (HCC) samples were used to study point mutation of p53 gene at 249 codon in the exon 7 by polymerase chain reaction and gel electrophoresis under Hae III enzyme digestion. Paraffin 0-8 P53 Homo sapiens 94-97 8879300-2 1996 The accumulation of p53 protein was studied immunohistochemically using monoclonal antibody BP53-12 on formalin-fixed paraffin-embedded sections of 36 KS lesions, of which 14 were classified histologically as early type and 22 as spindle-cell or mixed type. Paraffin 118-126 P53 Homo sapiens 20-23 21541525-3 1996 We have recently studied the steady-state levels of mRNA transcripts for bcl-2, bar and P53 in 8 MM cell lines and found inverse correlation between the levels of bcl-2 mRNA transcripts and sensitivity to dexamethasone (DEX) induced apoptosis.

Oligonucleotides 10-25 P53 Homo sapiens 56-59 8761369-0 1996 TP53 mutation analyses on breast carcinomas: a study of paraffin-embedded archival material. Paraffin 56-64 P53 Homo sapiens 0-4 8761369-1 1996 The aim of this investigation was to examine the possibility of analysing TP53 mutations in archival paraffin-embedded material with the constant denaturant gel electrophoresis (CDGE) method. Paraffin 101-109 P53 Homo sapiens 74-78 21541525-5 1996 In this study, we determined the steady-state levels of bcl-2, P53 and bar proteins in 4 myeloma cell lines, and the levels were correlated with sensitivity to DEX induced apoptosis. Dexamethasone 160-163 P53 Homo sapiens 63-66 21541525-10 1996 Induction of apoptosis in the DEX sensitive cells resulted in an early down-regulation of bcl-2 and P53 protein, whereas the levels of bar protein were only slightly decreased. Dexamethasone 30-33 P53 Homo sapiens 100-103 21541525-11 1996 In contrast to the DEX sensitive cell lines, the levels of bcl-2, bar and P53 proteins in the DEX resistant cell lines were unchanged during 72 h of treatment with DEX. Dexamethasone 94-97 P53 Homo sapiens 74-77 21541525-11 1996 In contrast to the DEX sensitive cell lines, the levels of bcl-2, bar and P53 proteins in the DEX resistant cell lines were unchanged during 72 h of treatment with DEX. Dexamethasone 94-97 P53 Homo sapiens 74-77 8881915-2 1996 METHODS: Expression of p53 was evaluated immunocytochemically in a retrospective study of formalin fixed, paraffin wax embedded tissue. Paraffin 106-118 P53 Homo sapiens 23-26 8797205-1 1996 Evaluation of the p53 gene protein expression and proliferative potential with MIB-1 monoclonal antibody (MBL Co.), a new marker of cellular proliferation that binds Ki67 in paraffin sections, by immunohistochemical studies were made in 10 cases of the non-recurrent meningiomas and the 8 cases (17 samples) of the recurrent meningiomas. Paraffin 174-182 P53 Homo sapiens 18-21 8760308-4 1996 We show here that A-T cells are more sensitive than normal lymphoblastoid cells to cisplatin treatment but the rate of induction of p53 by cisplatin is similar in both cell types. Cisplatin 139-148 P53 Homo sapiens 132-135 8707413-5 1996 Ad-p53, but not Ad-LacZ, infection of cancer cells was followed by nuclear accumulation of the CDK inhibitor p21WAFI/CIPI, cell cycle arrest and loss of viability. cipi 117-121 P53 Homo sapiens 3-6 8760308-6 1996 The use of a reporter assay to determine the functional status of p53 confirmed the results obtained in the induction experiments with cisplatin. Cisplatin 135-144 P53 Homo sapiens 66-69 8912347-3 1996 In this study we examined both benign and borderline malignant/malignant mucinous neoplasms for p53 protein accumulation by the means of an anti-human p53 protein monoclonal antibody on paraffin sections. Paraffin 186-194 P53 Homo sapiens 96-99 8707413-8 1996 Ad-p53-infected SKBr3 breast cancer cells were more sensitive to cytotoxicity of the DNA damaging drugs mitomycin C or Adriamycin, but not the M-phase specific drug vincristine. Doxorubicin 119-129 P53 Homo sapiens 3-6 8707413-9 1996 Our results suggest that Ad-p53 is capable of infecting and killing cancer cells of diverse tissue origins (including multi-drug resistant cancer cells), that p21WAFI/CIPI may be a useful marker of p53 infectivity and that there may be synergy between Ad-p53 and either mitomycin C or Adriamycin induced cell death in tumors with p53 mutations. Doxorubicin 285-295 P53 Homo sapiens 28-31 8667426-15 1996 UCN-01 markedly enhanced the cell-killing activity of cisplatin in MCF-7 cells defective for p53 function.

Paclitaxel 19-24 P53 Homo sapiens 69-72 8763853-4 1996 We examined the induction of p53 and its downstream target, p21WAF1/CIP1, by the microtubule active agents taxol and vinblastine with radiation. Paclitaxel 107-112 P53 Homo sapiens 29-32 8763853-5 1996 An increase in induction of both p53 and p21 WAF1/CIP1 was demonstrated when radiation was added to either taxol or vinblastine treatment. Paclitaxel 107-112 P53 Homo sapiens 33-36 8706243-4 1996 Methotrexate-resistant MCF-7 cells were unusual heterozygotes that expressed a wild-type and dominant, in-frame p53 deletion mutant and the doxorubicin-resistant cells expressed only mutant p53. Doxorubicin 140-151 P53 Homo sapiens 190-193 8809407-4 1996 In this study, we showed that mimosine can increase both p21 mRNA and protein levels, indirectly inhibit cyclin E-associated kinase activity without affecting the cyclin E protein level, block human breast cancer cells (21PT) in the late G1 phase of the cell cycle, and induce a p53-independent p21 pathway in these cells.

Oligonucleotides 14-29 P53 Homo sapiens 0-3 8903423-7 1996 The effects of the vitamin D compounds on the expression of two oncoproteins which may regulate apoptosis, bcl-2 and p53 were examined by Western analysis. Vitamin D 19-28 P53 Homo sapiens 117-120 8903423-9 1996 In addition, the p21 protein, whose gene WAF-1 is induced by wild type p53, was also increased by both vitamin D compounds.

Oligonucleotides 48-63 P53 Homo sapiens 34-37 8698624-3 1996 Treatment of DLD-1 cells with the p53 antisense oligonucleotide caused a decrease in the level of p53 mutant protein. Oligonucleotides 48-63 P53 Homo sapiens 98-101 8674115-3 1996 This exonuclease activity is intrinsic to the wild-type p53 protein: it copurified with p53 during p53 preparation; only purified wild-type p53, but not identically purified mutant p53 proteins displayed exonuclease activity; the exonuclease activity could be reconstituted from SDS gel-purified and urea-renatured p53 protein and mapped to the core domain of the p53 molecule; and finally, purified p53 protein could be UV-cross-linked to GMP.

Acetylcysteine 27-43 P53 Homo sapiens 116-119 8743957-6 1996 Pretreatment of cells with N-acetylcysteine, an agent known to counteract oxidative stress, attenuates the cellular p53 response to ultraviolet light by reducing the number of cells with high p53 levels but does not affect the response to ionizing radiation. Acetylcysteine 27-43 P53 Homo sapiens 192-195 8819013-3 1996 These mutations result in an Arg-->Trp amino acid substitution at residue 249 and an Ile-->Phe amino acid substitution at residue 255 in a highly conserved region in the DNA-binding core domain of the p53 protein. Arginine 29-32 P53 Homo sapiens 207-210 8819013-3 1996 These mutations result in an Arg-->Trp amino acid substitution at residue 249 and an Ile-->Phe amino acid substitution at residue 255 in a highly conserved region in the DNA-binding core domain of the p53 protein. Tryptophan 38-41 P53 Homo sapiens 207-210 8819013-4 1996 To determine the effects of these substitutions on the three-dimensional structure of the p53 protein, we have performed molecular dynamics calculations on this core domain of the wild-type and the Trp-249 and Phe-255 mutants to compute the average structures of each of the three forms.

Linoleic Acid 32-45 P53 Homo sapiens 77-80 8603385-1 1996 The effects of two food-related chemicals (sodium saccharin and linoleic acid) on the levels of Her2/neu and p53 mRNA in a non-cancerous human breast epithelial cell line (HBL-100) were tested in comparison with the effects of the known tumor promoter phorbol 12-myristate 13-acetate (TPA). Linoleic Acid 64-77 P53 Homo sapiens 109-112 8612815-2 1996 With the use of NO donors such as S-nitrosoglutathione or spermine-NO we established that PARP digestion occurs in parallel with DNA fragmentation, and is preceded by accumulation of the tumor suppressor gene product p53. S-Nitrosoglutathione 34-54 P53 Homo sapiens 217-220 8606380-5 1996 METHODS: Immunohistochemical analysis with a monoclonal antibody (DO7) specific for p53 protein was used to detect expression of the protein in formalin-fixed, paraffin-embedded tumor samples from 69 head and neck cancer patients treated with definitive local therapy (surgery and/or radiotherapy) between January 1980 and October 1983 at The University of Texas M.

Paraffin 53-61 P53 Homo sapiens 26-29 21544419-0 1996 The role of p53, bcl-2 and bax network in dexamethasone induced apoptosis in multiple myeloma cell lines. Dexamethasone 42-55 P53 Homo sapiens 12-15 21544419-3 1996 We, therefore, decided to conduct a detailed study of the role of the bcl-2/bax/p53 network in dexamethasone (DEX) induced apoptosis in MM cells. Dexamethasone 95-108 P53 Homo sapiens 80-83 21544419-3 1996 We, therefore, decided to conduct a detailed study of the role of the bcl-2/bax/p53 network in dexamethasone (DEX) induced apoptosis in MM cells. Dexamethasone 110-113 P53 Homo sapiens 80-83 21544419-9 1996 Induction of apoptosis in 8226 and ARP-1 cells (DEX sensitive) resulted, within 24 h, in a transient but marked down-regulation of mRNA transcripts for bcl-2 and p53, whereas the level of expression of bax mRNA transcripts were unchanged, except for ARP-1 cells (lacking p53), where slight down-regulation of mRNA transcripts for bax, was observed. Dexamethasone 48-51 P53 Homo sapiens 162-165 21544419-9 1996 Induction of apoptosis in 8226 and ARP-1 cells (DEX sensitive) resulted, within 24 h, in a transient but marked down-regulation of mRNA transcripts for bcl-2 and p53, whereas the level of expression of bax mRNA transcripts were unchanged, except for ARP-1 cells (lacking p53), where slight down-regulation of mRNA transcripts for bax, was observed. Dexamethasone 48-51 P53 Homo sapiens 271-274 21544419-10 1996 In contrast to the DEX sensitive cell lines, the level of expression of bcl-2, bax and p53 mRNA transcripts in the DEX resistant cell lines, were unchanged during 72 h of treatment with DEX (up to 10 mu M).

Oligonucleotides 91-106 P53 Homo sapiens 60-63 21544419-11 1996 We, therefore, conclude that bcl-2 and perhaps p53 are involved in resistance to DEX in myeloma cell lines. Dexamethasone 81-84 P53 Homo sapiens 47-50 8599213-5 1996 Mutation of lysine residues within the C-terminus of p53 resulted in resistance to E6-mediated degradation in vitro, although the ability of the two proteins to form a complex was not affected. Lysine 12-18 P53 Homo sapiens 53-56 8733010-6 1996 Apoptosis can also be induced in immortalized steroidogenic granulosa cells, transformed by SV40 DNA and Ha-ras oncogene, by overexpression of the wild-type p53 tumor suppressor gene in cAMP-stimulated cells. Cyclic AMP 186-190 P53 Homo sapiens 157-160 8733010-7 1996 Omitting the cAMP stimulus prevents the p53-induced apoptosis in these cells, suggesting cross-talk between p53 and c-AMP-generated signals in the induction of apoptosis. Cyclic AMP 13-17 P53 Homo sapiens 40-43 8733010-7 1996 Omitting the cAMP stimulus prevents the p53-induced apoptosis in these cells, suggesting cross-talk between p53 and c-AMP-generated signals in the induction of apoptosis.

Nitric Oxide 0-12 P53 Homo sapiens 112-115 8637893-2 1996 Therefore, we hypothesized that p53 performs a similar role in response to putative endogenous mutagens, such as nitric oxide (NO). Nitric Oxide 113-125 P53 Homo sapiens 32-35 8649799-3 1996 Here we address this question in an intact cell system using normal human diploid fibroblasts in which p53 function is manipulated by expression of a dominant-negative mutant (ala(143)) introduced by a retroviral vector. Alanine 176-179 P53 Homo sapiens 103-106 8615678-8 1996 The level of the tumor suppressor p53 increases in response to NO donors like GSNO and effectively senses NO intoxication in macrophages. S-Nitrosoglutathione 78-82 P53 Homo sapiens 34-37 8615678-9 1996 GSNO removal concomitantly allows p53 to decline with only a small percentage of cells showing DNA fragmentation.

Paraffin 50-58 P53 Homo sapiens 83-86 8631030-8 1996 The delay in S phase progression was coincident with the induction of p53 protein levels in LXSN-containing HFFs, suggesting a role for p53 in DNA repair of cisplatin-induced damage.

Cisplatin 204-213 P53 Homo sapiens 144-147 8630996-11 1996 A significant correlation has been found between p53 accumulation, type of mutation (i.e., missense mutations), and pathological response to cisplatin-based therapy. Cisplatin 141-150 P53 Homo sapiens 49-52 8603737-3 1996 We found that phorbol myristate acetate (PMA) activates the src family tyrosine kinases p58c-fgr and p53/56lyn in suspended PMNs. Tetradecanoylphorbol Acetate 41-44 P53 Homo sapiens 101-104 8603737-4 1996 Moreover, we found that up to about 20% of p58c-fgr and p53/56lyn redistribute to a Triton X-100-insoluble fraction after PMA stimulation, and it is this fraction of the two kinases which diplays an increased activity. Tetradecanoylphorbol Acetate 122-125 P53 Homo sapiens 56-59 8603737-5 1996 These changes of p58c-fgr and p53/56lyn distribution and activity correlate with tyrosine phosphorylation of endogenous substrates.

Paraffin 118-126 P53 Homo sapiens 37-40 9081399-20 1996 Several genes are involved in control of this process; these include the p53 gene, mutations of which have been linked to cisplatin resistance in our laboratory studies, as well as in clinical trials with carboplatin. Cisplatin 122-131 P53 Homo sapiens 73-76 8954175-1 1996 The polymerase chain reaction and HaeIII enzymatic digestion were used to study the seventh exon of the p53 gene in 29 primary and recurrent hepatomas in paraffin-embedded samples from 11 patients.

Paclitaxel 186-196 P53 Homo sapiens 120-123 8564846-3 1996 Reduced levels of p53 correlated with increased G2/M phase arrest, micronucleation, and p53-independent paclitaxel-induced apoptosis. Paclitaxel 104-114 P53 Homo sapiens 18-21 8564846-3 1996 Reduced levels of p53 correlated with increased G2/M phase arrest, micronucleation, and p53-independent paclitaxel-induced apoptosis. Paclitaxel 104-114 P53 Homo sapiens 88-91 8979269-6 1996 A253-p53 cells could be distinguished from native A253 cells by prolonged doubling times (2-5 fold) and by a marked reduction of [3H]-thymidine uptake. Tritium 130-132 P53 Homo sapiens 5-8 8549741-3 1995 The p53BP2-PP1 complex was stable to NaCl at concentrations which dissociate the p53-p53BP2 complex, and the binding of PP1 and p53 to p53BP2 was mutually exclusive. Sodium Chloride 37-41 P53 Homo sapiens 4-7 8533007-2 1996 The latter are exemplified by protein thiol modification followed by subsequent NAD(+)-dependent automodification of the glycolytic enzyme GAPDH, or by mechanisms inducing accumulation of the tumor suppressor gene p53 and causing apoptotic cell death.

Paraffin 72-80 P53 Homo sapiens 32-35 8732103-1 1996 Silver staining PCR-SSCP method was used to detect point mutation of p53 gene in paraffin-embedded malignant fibrous histiocytoma (MFH) tissues. Paraffin 81-89 P53 Homo sapiens 69-72 8549741-3 1995 The p53BP2-PP1 complex was stable to NaCl at concentrations which dissociate the p53-p53BP2 complex, and the binding of PP1 and p53 to p53BP2 was mutually exclusive. Sodium Chloride 37-41 P53 Homo sapiens 81-84 8521385-0 1995 Microtubule-active drugs taxol, vinblastine, and nocodazole increase the levels of transcriptionally active p53. Nocodazole 49-59 P53 Homo sapiens 108-111 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes.

Paclitaxel 25-30 P53 Homo sapiens 108-111 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes. Paclitaxel 60-65 P53 Homo sapiens 132-135 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes. Nocodazole 84-94 P53 Homo sapiens 108-111 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes. Nocodazole 84-94 P53 Homo sapiens 132-135 8521409-4 1995 We show here that cis-diamminedichloroplatinum (cisplatin) induces the expression of interleukin-1 beta-converting enzyme (ICE), a mammalian homologue of the Caenorhabditis elegans cell death gene ced-3, in murine and human malignant glioma cells during apoptosis regardless of their p53 status. Cisplatin 18-46 P53 Homo sapiens 284-287 8521409-4 1995 We show here that cis-diamminedichloroplatinum (cisplatin) induces the expression of interleukin-1 beta-converting enzyme (ICE), a mammalian homologue of the Caenorhabditis elegans cell death gene ced-3, in murine and human malignant glioma cells during apoptosis regardless of their p53 status. Cisplatin 48-57 P53 Homo sapiens 284-287 8924223-9 1995 These findings indicate altered expression of p53 protein occurs in H&N lymphomas, especially in late event lymphoma progression and appears to play a role in the development of EBER positive T cell lymphomas. Adenosine Monophosphate 70-73 P53 Homo sapiens 46-49 8599466-1 1995 The accumulation of p53 protein was studied immunohistochemically on paraffin-embedded sections of 26 Spitz nevi (SNs), 26 primary invasive cutaneous malignant melanomas (MMs), 20 metastases of MM, and 17 ordinary compound nevi (CNs), using monoclonal antibody BP53-12. Paraffin 69-77 P53 Homo sapiens 20-23 8599466-4 1995 We believe that the immunohistochemical detection of p53 protein with the use of monoclonal antibodies such as BP53-12 on paraffin sections, especially when strong nuclear reactivity is demonstrated, may prove to be an adjunctive tool in the histopathologic differentiation of MM from SN.

Paraffin 120-128 P53 Homo sapiens 60-63 7499360-5 1995 Supplementation of culture medium containing charcoal-treated calf serum with 0.1-1 nM 17 beta-estradiol restored p53 to its normal levels. Estradiol 90-104 P53 Homo sapiens 114-117 7499360-9 1995 Since estradiol is known to promote cell proliferation, the induction of p53 observed in this study leads us to propose that estradiol stimulates p53 to regulate proliferation of T47D cells in culture. Estradiol 6-15 P53 Homo sapiens 73-76 7499360-9 1995 Since estradiol is known to promote cell proliferation, the induction of p53 observed in this study leads us to propose that estradiol stimulates p53 to regulate proliferation of T47D cells in culture. Estradiol 6-15 P53 Homo sapiens 146-149 7499360-9 1995 Since estradiol is known to promote cell proliferation, the induction of p53 observed in this study leads us to propose that estradiol stimulates p53 to regulate proliferation of T47D cells in culture. Estradiol 125-134 P53 Homo sapiens 73-76 7499360-9 1995 Since estradiol is known to promote cell proliferation, the induction of p53 observed in this study leads us to propose that estradiol stimulates p53 to regulate proliferation of T47D cells in culture. Estradiol 125-134 P53 Homo sapiens 146-149 8519417-5 1995 Transient wild-type p53 expression after high-efficiency gene transfer by a p53 adenovirus also sensitized the cells to cisplatin and correlated with the induction of apoptosis. Cisplatin 120-129 P53 Homo sapiens 20-23 8640471-0 1995 Immunohistochemical detection of p53 overexpression in formalin-fixed, paraffin-embedded sections of endometrial carcinoma. Paraffin 71-79 P53 Homo sapiens 33-36 8640471-2 1995 However using CM1 and an enhanced method based on microwave heating and protease digestion enabled the immunohistochemical detection of p53 overexpression in formalin-fixed, paraffin-embedded sections of endometrial carcinoma, although very few positive stainings were obtained without such an enhanced treatment. Paraffin 174-182 P53 Homo sapiens 136-139 8640471-7 1995 CONCLUSION: Enhanced immunodetection of p53 in paraffin-embedded tissues will provide a useful alternative to the usual fresh-tissue assay. Paraffin 47-55 P53 Homo sapiens 40-43 8519417-4 1995 Stable transfectants that co-expressed mutant and wild-type p53 had enhanced sensitivity to cisplatin and gamma radiation, compared with parental cells, control vector-transduced cells, and transduced cells that had lost expression of wild-type p53. Cisplatin 92-101 P53 Homo sapiens 60-63 8519417-5 1995 Transient wild-type p53 expression after high-efficiency gene transfer by a p53 adenovirus also sensitized the cells to cisplatin and correlated with the induction of apoptosis. Cisplatin 120-129 P53 Homo sapiens 76-79 7477163-0 1995 More on p53 antigen loss in stored paraffin slides. Paraffin 35-43 P53 Homo sapiens 8-11 8751332-4 1995 To explore the differences in the expression of p53 protein in these two tumor types, we performed immunohistochemistry on 10 conventional pulmonary adenocarcinomas and 12 bronchioalveolar carcinomas on formalin-fixed and paraffin-embedded material, using the commercially available monoclonal antibody against the mutant p53 protein. Paraffin 222-230 P53 Homo sapiens 48-51 7578083-5 1995 In many cancers, the most frequent class of mutations is C to T changes within CG dinucleotides of the tumor suppressor gene p53. cytidylyl-3'-5'-guanosine 79-95 P53 Homo sapiens 125-128 7478539-0 1995 UREB1, a tyrosine phosphorylated nuclear protein, inhibits p53 transactivation. Tyrosine 9-17 P53 Homo sapiens 59-62 7478539-7 1995 These data suggest that optimal suppression of p53 transactivation requires tyrosine phosphorylated UREB1 and that tyrosine phosphorylation and dephosphorylation processes may be involved in the regulation of p53 transactivation. Tyrosine 76-84 P53 Homo sapiens 47-50 7478539-7 1995 These data suggest that optimal suppression of p53 transactivation requires tyrosine phosphorylated UREB1 and that tyrosine phosphorylation and dephosphorylation processes may be involved in the regulation of p53 transactivation. Tyrosine 115-123 P53 Homo sapiens 209-212 7585548-0 1995 Aberrant p53 expression predicts clinical resistance to cisplatin-based chemotherapy in locally advanced non-small cell lung cancer. Cisplatin 56-65 P53 Homo sapiens 9-12 7479838-3 1995 We show that alanine substitution mutations in a single loop of TBP can disrupt its association in vitro with the activation domains of the herpes simplex virus activator VP16 and of the human tumor suppressor protein p53; these mutations do not, however, disrupt the transcriptional response of TBP to either activation domain in vivo. Alanine 13-20 P53 Homo sapiens 218-221 7585548-2 1995 In vitro studies indicate that p53 can modulate cisplatin-induced cytotoxicity, but the molecular genetic features determining response or resistance to cisplatin in vivo must be defined. Cisplatin 48-57 P53 Homo sapiens 31-34 7585548-8 1995 Only 7 of 52 cases examined before and after chemotherapy treatment exhibited a change in the level of p53 expression after cisplatin-based chemotherapy. Cisplatin 124-133 P53 Homo sapiens 103-106 7585548-9 1995 These results indicate that cisplatin alters p53 expression infrequently and suggest a direct link between aberrant p53 expression and resistance to cisplatin-based chemotherapy in NSCLC. Cisplatin 28-37 P53 Homo sapiens 45-48 7585548-9 1995 These results indicate that cisplatin alters p53 expression infrequently and suggest a direct link between aberrant p53 expression and resistance to cisplatin-based chemotherapy in NSCLC. Cisplatin 149-158 P53 Homo sapiens 116-119 8697990-7 1995 Immunohistochemistry (ABC method) on section of paraffin embedded tissue is a reliable method for detecting c-myc and p53 gene expression in HCC.

Paraffin 96-104 P53 Homo sapiens 39-42 8822113-1 1995 The expression of p53 and bcl-2 was immunohistochemically investigated in 61 formalin-fixed, paraffin-embedded invasive breast carcinomas. Paraffin 93-101 P53 Homo sapiens 18-21 8745486-2 1995 METHODS: Expression of p53 was studied by immunohistochemistry in paraffin sections from 23 normal endometrium, 44 endometrial hyperplasia and 103 endometrial carcinoma. Paraffin 66-74 P53 Homo sapiens 23-26 7553639-0 1995 Taxol induction of p21WAF1 and p53 requires c-raf-1. Paclitaxel 0-5 P53 Homo sapiens 31-34 7559631-6 1995 An in vitro glutathione S-transferase pull-down assay establishes a linear correlation between p53 TAD-mediated transactivation in vivo and the binding activity of p53 TAD to TATA-binding protein (TBP) in vitro. Glutathione 12-23 P53 Homo sapiens 95-98 7559631-6 1995 An in vitro glutathione S-transferase pull-down assay establishes a linear correlation between p53 TAD-mediated transactivation in vivo and the binding activity of p53 TAD to TATA-binding protein (TBP) in vitro. Glutathione 12-23 P53 Homo sapiens 164-167 7579380-6 1995 The results of immunohistochemistry analysis using a monoclonal anti-p53 antibody on paraffin-embedded specimens were compared with the SSCP data, the tumor karyotypes, and clinical course of each patient. Paraffin 85-93 P53 Homo sapiens 69-72 7588628-1 1995 Cisplatin treatment of Epstein-Barr virus-immortalized human B lymphoblastoid cell lines (LCLs) results in p53-mediated apoptosis which occurs largely in a population of cells at the G1/S boundary of the cell cycle. Cisplatin 0-9 P53 Homo sapiens 107-110 7553639-8 1995 Previous depletion of c-raf-1 inhibited both the p21WAF1- and p53-inducing properties of taxol, as well as the activation of MAP kinase. Paclitaxel 89-94 P53 Homo sapiens 62-65 7553639-10 1995 Furthermore, the ability of taxol to both induce wild-type p53 in MCF7 cells and activate MAP kinase is also dependent on c-raf-1 expression. Paclitaxel 28-33 P53 Homo sapiens 59-62 7553639-3 1995 Herein, we show that taxol induced dose- and time-dependent accumulation of the cyclin inhibitor p21WAF1 in both p53 wild-type and p53-null cells, although the degree of induction was greater in cells expressing wild-type p53. Paclitaxel 21-26 P53 Homo sapiens 113-116 7553639-3 1995 Herein, we show that taxol induced dose- and time-dependent accumulation of the cyclin inhibitor p21WAF1 in both p53 wild-type and p53-null cells, although the degree of induction was greater in cells expressing wild-type p53. Paclitaxel 21-26 P53 Homo sapiens 131-134 7553639-3 1995 Herein, we show that taxol induced dose- and time-dependent accumulation of the cyclin inhibitor p21WAF1 in both p53 wild-type and p53-null cells, although the degree of induction was greater in cells expressing wild-type p53. Paclitaxel 21-26 P53 Homo sapiens 131-134 7553639-4 1995 In MCF7 cells, wild-type p53 protein was also induced after taxol treatment, and this induction was mediated primarily by increased protein stability. Paclitaxel 60-65 P53 Homo sapiens 25-28 7553639-5 1995 Taxol induced both p21WAF1 and wild-type p53 optimally in MCF7 cells after 20-24-h exposure with an EC50(3) of 5 nM. Paclitaxel 0-5 P53 Homo sapiens 41-44 7553639-6 1995 In p53-null PC3M cells, p21WAF1 was similarly induced after 24-h exposure to taxol. Paclitaxel 77-82 P53 Homo sapiens 3-6 8590632-0 1995 Iron deprivation results in an increase in p53 expression. Iron 0-4 P53 Homo sapiens 43-46 7478541-4 1995 Examination of Bcl-2 and p53 protein levels in pairs of cis-platin sensitive and resistant ovarian cell lines demonstrated that the resistant variants over-express Bcl-2 and/or p53, apparently due to progressive expansion of Bcl-2 and/or p53 positive subpopulations during the in vitro development of resistance. Cisplatin 56-66 P53 Homo sapiens 25-28 7488003-0 1995 Phorbol esters attenuate the expression of p53 in cells treated with doxorubicin and protect TS-P53/K562 from apoptosis. Doxorubicin 69-80 P53 Homo sapiens 43-46 7488003-1 1995 The induction of p53 by doxorubicin in normal human fibroblasts was completely reverted by TPA, a phorbol ester. Doxorubicin 24-35 P53 Homo sapiens 17-20 8590632-1 1995 Deferoxamine (DFO)-induced iron deprivation caused an increase in p53 expression in ML-1 and Raji cells. Iron 27-31 P53 Homo sapiens 66-69 8590632-5 1995 Although increases in wild type p53 protein in ML-1 cells resulted in increases in a p53 target gene, p21cipl/wafl/sdil, this effect was not observed in Raji cells which express a mutant p53 protein. sdil 115-119 P53 Homo sapiens 32-35 8590632-5 1995 Although increases in wild type p53 protein in ML-1 cells resulted in increases in a p53 target gene, p21cipl/wafl/sdil, this effect was not observed in Raji cells which express a mutant p53 protein. sdil 115-119 P53 Homo sapiens 85-88 8590632-5 1995 Although increases in wild type p53 protein in ML-1 cells resulted in increases in a p53 target gene, p21cipl/wafl/sdil, this effect was not observed in Raji cells which express a mutant p53 protein. sdil 115-119 P53 Homo sapiens 85-88 9815913-3 1995 To test the hypothesis that a p53 mutation could result in tamoxifen resistance and estrogen-independent growth, the MCF-7 cell line was transfected with p53 cDNA which was mutated at codon 179 (histidine to glutamine). Tamoxifen 59-68 P53 Homo sapiens 30-33 8630898-2 1995 METHODS: p53 protein expression was studied by immunohistochemistry from paraffin embedded tissue in a series of 136 patients with malignant ovarian epithelial tumors. Paraffin 73-81 P53 Homo sapiens 9-12 9815913-4 1995 MCF-7 is an estrogen receptor-positive, estrogen-dependent, tamoxifen-sensitive cell line with only wild-type p53. Tamoxifen 60-69 P53 Homo sapiens 110-113 7560079-6 1995 While p53 was detected in MCF-7 cells, evidence for TPA-induced stimulation of p53 transcriptional activity was not evident. Tetradecanoylphorbol Acetate 52-55 P53 Homo sapiens 79-82 8575459-2 1995 Differences in the p53 content in extracts from the p53 antisense transfected HeLa clones compared to the parental HeLa cells were demonstrated by protein binding to the p53 consensus oligonucleotide and in transactivation assays.

Paraffin 57-65 P53 Homo sapiens 13-16 7560890-3 1995 In breast cancer, we observed a poor correlation (rs = 0.17) between P53 expression and proliferative activity evaluated as [3H]-thymidine ([3H]-dT) labeling index and an independent prognostic relevance of the two variables. Tritium 125-127 P53 Homo sapiens 69-72 7560890-3 1995 In breast cancer, we observed a poor correlation (rs = 0.17) between P53 expression and proliferative activity evaluated as [3H]-thymidine ([3H]-dT) labeling index and an independent prognostic relevance of the two variables. Tritium 125-128 P53 Homo sapiens 69-72 7560890-7 1995 A weak direct relation between P53 positivity and [3H]-dT incorporation (rs = 0.4) was observed on the overall series of P53+ tumors and was maintained in subgroups defined by several biological and pathological features, except for estrogen receptor-negative tumors.

Nitric Oxide 0-12 P53 Homo sapiens 64-67 8519683-1 1995 We have earlier shown that wild-type (wt) p53 expressed from a temperature-sensitive construct (ts p53) triggers apoptosis in the v-myc retrovirus-induced, p53-negative T-cell lymphoma line J3D (Y. Wang et al., Cell Growth & Differ., 4: 467-473, 1993). Adenosine Monophosphate 224-227 P53 Homo sapiens 42-45 7667317-4 1995 Cells released from a mimosine block early in S phase stopped predominantly in G2/M in the presence of p53, confirming that p53 can mediate arrest at this stage, as well as in G1. Mimosine 22-30 P53 Homo sapiens 103-106 8575232-2 1995 Quantitative analysis of P53 protein expression was performed on paraffin-embedded tissues from 55 smooth muscle tumors of the gastrointestinal tract, using immunofluorescence and flow cytometry.

Arginine 56-64 P53 Homo sapiens 34-37 7594817-2 1995 A-7 was found to contain a mutant p53 gene in which the arginine codon at position 175 was substituted by a histidine codon. Histidine 108-117 P53 Homo sapiens 34-37 7472782-3 1995 p53 expression was evaluated by immunohistochemistry in formalin-fixed, paraffin-embedded tissue from 23 leiomyosarcomas, 10 tumours of uncertain malignant potential (TUMPs), and 18 leiomyomas.

Fluorouracil 138-150 P53 Homo sapiens 16-19 7657383-0 1995 Detection of TP53 gene mutation in human meningiomas: a study using immunohistochemistry, polymerase chain reaction/single-strand conformation polymorphism and DNA sequencing techniques on paraffin-embedded samples. Paraffin 189-197 P53 Homo sapiens 13-17 7657383-7 1995 In this case, we identified a mutation in the TP53 gene at codon 161 changing GCC to ACC and resulting in an alteration of alanine to threonine in this position. Alanine 123-130 P53 Homo sapiens 46-50 7657383-7 1995 In this case, we identified a mutation in the TP53 gene at codon 161 changing GCC to ACC and resulting in an alteration of alanine to threonine in this position. Threonine 134-143 P53 Homo sapiens 46-50 7627952-4 1995 Here we show that mAb PAb421 when microinjected into human SW480 colorectal carcinoma cells restores the transcription activation function to the resident mutant p53 (arg to his 273, pro to ser 309). Arginine 167-170 P53 Homo sapiens 162-165 7627952-4 1995 Here we show that mAb PAb421 when microinjected into human SW480 colorectal carcinoma cells restores the transcription activation function to the resident mutant p53 (arg to his 273, pro to ser 309). Histidine 174-177 P53 Homo sapiens 162-165 7627952-4 1995 Here we show that mAb PAb421 when microinjected into human SW480 colorectal carcinoma cells restores the transcription activation function to the resident mutant p53 (arg to his 273, pro to ser 309). Serine 190-193 P53 Homo sapiens 162-165 7614454-6 1995 This is the first report where germline transmission of replication-damaged p53 trinucleotide repeats is associated with the Li-Fraumeni syndrome. trinucleotide 80-93 P53 Homo sapiens 76-79 7559095-2 1995 The wild-type p53 gene has a polymorphism at codon 72 that presents the arginine (CGC) or proline (CCC) genotype, which recently has been reported to be associated with genetically determined susceptibility to smoking-related lung cancers. Arginine 72-80 P53 Homo sapiens 14-17 9816057-0 1995 Induction of apoptosis and cell cycle-specific change in expression of p53 in normal lymphocytes and MOLT-4 leukemic cells by nitrogen mustard. Nitrogen 126-134 P53 Homo sapiens 71-74 9816057-5 1995 Exposure of normal lymphocytes to 5 microM nitrogen mustard caused their arrest in G1, an increase in p53 expression which was maximal in such cells, and significant apoptosis in cells located beyond the arrest point (S and G2 + M cells). Nitrogen 43-51 P53 Homo sapiens 102-105 9816057-7 1995 Expression of p53 was highest for S and G2 + M MOLT-4 cells in response to the nitrogen mustard. Nitrogen 79-87 P53 Homo sapiens 14-17 9816057-9 1995 These data suggest that DNA damage caused by nitrogen mustard provides a signal that results in stabilization of wild-type p53, preferentially in G1 cells, causes cell arrest in G1, and induces apoptosis of the cells that either were in the S-phase at the time of drug administration and/or escaped G1 arrest. Nitrogen 45-53 P53 Homo sapiens 123-126 16696005-1 1995 Aim-To investigate the expression of p53 protein in invasive squamous cell carcinoma (SCC) of the larynx and dysplasia in relation to histological grade and tobacco smoking.Method-Paraffin wax embedded tissue sections from 41 cases of invasive SCC of the larynx, 28 cases of dysplasia and 14 control laryngeal biopsy specimens were studied immunohistochemically using two anti-p53 monoclonal antibodies (DO7 and 1801).

Chlormequat 99-102 P53 Homo sapiens 14-17 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Fluorouracil 109-123 P53 Homo sapiens 151-154 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Fluorouracil 109-123 P53 Homo sapiens 174-177 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Fluorouracil 109-123 P53 Homo sapiens 174-177 8625105-5 1995 Immunohistochemical staining for p53 was performed on paraffin embedded tissue of each case. Paraffin 54-62 P53 Homo sapiens 33-36 7624152-9 1995 In the present study, the wild type p53 protein in human fibrosarcoma HT1080 cells were targeted with HPV-18 E6 and the viability of these cells in response to treatment with adriamycin, u.v.-irradiation and gamma-irradiation was examined. Doxorubicin 175-185 P53 Homo sapiens 36-39 7624116-1 1995 A human p53 mutant, p53Val-138 (amino acid 138, Alanine-->Valine), generated by in vitro mutagenesis was introduced into Saos-2 human osteosarcoma and Jurkat acute T-lymphoblastic leukemia cell lines, both lacking p53 protein expression. Alanine 48-55 P53 Homo sapiens 8-11 7624116-1 1995 A human p53 mutant, p53Val-138 (amino acid 138, Alanine-->Valine), generated by in vitro mutagenesis was introduced into Saos-2 human osteosarcoma and Jurkat acute T-lymphoblastic leukemia cell lines, both lacking p53 protein expression. Alanine 48-55 P53 Homo sapiens 20-23 7624134-0 1995 Cdk2 kinase phosphorylates serine 315 of human p53 in vitro. Serine 27-33 P53 Homo sapiens 47-50 7624134-8 1995 Mutation of serine 315 of p53 to alanine (p53-S315A) abolished phosphorylation by cdk2 kinase.

Alanine 33-40 P53 Homo sapiens 26-29 7624134-8 1995 Mutation of serine 315 of p53 to alanine (p53-S315A) abolished phosphorylation by cdk2 kinase. Alanine 33-40 P53 Homo sapiens 42-45 7624134-10 1995 The results demonstrate that ser 315 of p53 is phosphorylated by cdk2 in vitro. Serine 29-32 P53 Homo sapiens 40-43 7624134-11 1995 However, ser 315 of wtp53 is not required for transcriptional activity in vivo, suggesting that cdk2 phosphorylation of p53 may be involved in regulating other cellular functions of wtp53. Serine 9-12 P53 Homo sapiens 22-25 7784087-2 1995 It has recently been shown (Lin et al., 1994b) that the transcriptional activator domain of the p53 protein contains two amino acids, leu-22 and trp-23, which are required by the wild-type p53 protein for transcriptional activity. Tryptophan 145-148 P53 Homo sapiens 96-99 21597798-6 1995 Western immunoblotting with commercial monoclonal antibodies and SDS-PAGE identified the isolated antigens as the p53 protein. Sodium Dodecyl Sulfate 65-68 P53 Homo sapiens 114-117 7784087-2 1995 It has recently been shown (Lin et al., 1994b) that the transcriptional activator domain of the p53 protein contains two amino acids, leu-22 and trp-23, which are required by the wild-type p53 protein for transcriptional activity. Tryptophan 145-148 P53 Homo sapiens 189-192 7611786-3 1995 All the cell lines expressing very low or undetectable level of sdil mRNA contains p53 gene abnormalities, while the cell lines expressing high level of sdil shares wild type p53 gene. sdil 64-68 P53 Homo sapiens 83-86 7546049-2 1995 Quantitation of DNA ploidy was determined on Feulgen-stained touch imprints with an image analyzer, whereas localization of the immunohistochemical reaction of Erb-B2 and p53 protein was evaluated in paraffin-embedded tumor specimens with microscopy. Paraffin 200-208 P53 Homo sapiens 171-174 7605578-3 1995 This p53 mutation resulted in the same change, an Arg-->Ser substitution, as in the human p53 gene at position 249. Arginine 50-53 P53 Homo sapiens 93-96 7539102-5 1995 Similarly, K562, cells stably transfected with a plasmid vector containing the temperature-sensitive human p53 mutant Ala-143 demonstrated a four- to sixfold upregulation of Fas/APO-1 by flow-cytometric analysis at the permissive temperature of 32.5 degrees C. Temperature-sensitive upregulation of Fas/APO-1 in K562 Ala-143 cells was verified by immunoprecipitation and demonstrated to result from enhanced mRNA production by nuclear run-on and Northern (RNA) analyses. Alanine 118-121 P53 Homo sapiens 107-110 7539102-6 1995 Stably transfected K562 cells expressing temperature-insensitive, transcriptionally inactive p53 mutants (His-175, Trp-248, His-273, or Gly-281) failed to upregulate Fas/APO-1 at either 32.5 degrees or 37.5 degrees C. The temperature-sensitive transcription of Fas/APO-1 occurred in the presence of cycloheximide, indicating that de novo protein synthesis was not required and suggested a direct involvement of p53. Tryptophan 115-118 P53 Homo sapiens 93-96 7761574-5 1995 We discovered p53 loss of heterozygosity and a point mutation in the remaining allele of the p53 gene in adriamycin-resistant cells.

Doxorubicin 105-115 P53 Homo sapiens 93-96 7761100-4 1995 In this study, we show that the expression of both wild-type p53 and MDM2 (murine double minute 2) proteins was induced when cis-diamminedichloroplatinum (cisplatin) caused apoptosis in human glioblastoma U87-MG cells, which expressed neither wild-type p53 nor MDM2 protein prior to treatment. Cisplatin 125-153 P53 Homo sapiens 253-256 7761100-4 1995 In this study, we show that the expression of both wild-type p53 and MDM2 (murine double minute 2) proteins was induced when cis-diamminedichloroplatinum (cisplatin) caused apoptosis in human glioblastoma U87-MG cells, which expressed neither wild-type p53 nor MDM2 protein prior to treatment. Cisplatin 155-164 P53 Homo sapiens 253-256 7743505-8 1995 This increase in the WAF1/Cip1 mRNA level was observed 30 min after irradiation and continued for at least 48 h. A mobility shift assay performed using the sequence of the putative p53 DNA binding site on the WAF1/Cip1 and GADD45 genes as a probe showed that nuclear protein extracted from primary thyroid cells, anti-p53 antibody, and probe oligonucleotide-bound complex was clearly shifted. Oligonucleotides 342-357 P53 Homo sapiens 181-184 7750085-4 1995 In contrast, thapsigargin antagonized only drug-induced nuclear accumulation of p53 protein.

Doxorubicin 13-24 P53 Homo sapiens 74-77 7729953-2 1995 In contrast, Doxorubicin was less cytotoxic in cells expressing wild-type p53 than in cells expressing no p53 or mutated p53.

Tetradecanoylphorbol Acetate 67-70 P53 Homo sapiens 170-173 7737366-0 1995 Involvement of p53 expression in cAMP-mediated apoptosis in immortalized granulosa cells. Cyclic AMP 33-37 P53 Homo sapiens 15-18 7737366-2 1995 In the present work, we examined the effect of overexpression of either wild-type or mutant p53 on cAMP-mediated apoptosis in steroidogenic granulosa cell lines transfected with SV40 DNA together with the Ha-ras oncogene and a temperature-sensitive variant of p53, p53val135. Cyclic AMP 99-103 P53 Homo sapiens 92-95 7737366-5 1995 Progesterone production in such cells treated with cAMP was significantly higher at 32 degrees C than at 37.5 degrees C, suggesting that wild-type p53 can also enhance granulosa cell differentiation. Progesterone 0-12 P53 Homo sapiens 147-150 7737366-5 1995 Progesterone production in such cells treated with cAMP was significantly higher at 32 degrees C than at 37.5 degrees C, suggesting that wild-type p53 can also enhance granulosa cell differentiation.

Cisplatin 0-4 P53 Homo sapiens 56-59 7712469-6 1995 CDDP sensitization was not limited to MCF-7 cells since p53 disruption in human colon carcinoma RKO cells also enhanced sensitivity to CDDP. Cisplatin 135-139 P53 Homo sapiens 56-59 7712469-7 1995 Contrary to the other DNA-damaging agents tested, CDDP-induced DNA lesions are repaired extensively by nucleotide excision, and in agreement with a defect in this process, MCF-7/E6 and MCF-7/mu-p53 cells exhibited a reduced ability to repair a CDDP-damaged chloramphenicol acetyltransferase-reporter plasmid transfected into the cells. Cisplatin 50-54 P53 Homo sapiens 194-197 7712469-8 1995 Therefore, we attributed the increased CDDP sensitivity of MCF-7 cells with disrupted p53 to defects in G1 checkpoint control, nucleotide excision repair, or both.

Histidine 90-93 P53 Homo sapiens 36-39 8082749-0 1994 Transient stabilization of p53 in non-small cell lung carcinoma cultures arrested for growth by retinoic acid. Tretinoin 96-109 P53 Homo sapiens 27-30 8082749-3 1994 Levels of p53 transcripts remained unchanged during the time of increases in protein expression in retinoic acid-treated H460a cells, suggesting that a post-translational mechanism was involved in the increased expression of the protein. Tretinoin 99-112 P53 Homo sapiens 10-13 8082749-4 1994 Pulse-chase analysis demonstrated that wild-type p53 was significantly more stabile in H460a cells treated with retinoic acid, exhibiting a half-life greater than 6 h, in contrast to 3 h for the protein in untreated control cells. Tretinoin 112-125 P53 Homo sapiens 49-52 8082749-5 1994 The retinoic acid-mediated effect was specific for wild-type p53, since expression of mutant p53 in the H596b and H322j cell lines remained relatively unchanged even after 72 h exposure to retinoic acid. Tretinoin 4-17 P53 Homo sapiens 61-64 8082749-5 1994 The retinoic acid-mediated effect was specific for wild-type p53, since expression of mutant p53 in the H596b and H322j cell lines remained relatively unchanged even after 72 h exposure to retinoic acid. Tretinoin 4-17 P53 Homo sapiens 93-96 8082749-5 1994 The retinoic acid-mediated effect was specific for wild-type p53, since expression of mutant p53 in the H596b and H322j cell lines remained relatively unchanged even after 72 h exposure to retinoic acid. Tretinoin 189-202 P53 Homo sapiens 61-64 8082749-5 1994 The retinoic acid-mediated effect was specific for wild-type p53, since expression of mutant p53 in the H596b and H322j cell lines remained relatively unchanged even after 72 h exposure to retinoic acid. Tretinoin 189-202 P53 Homo sapiens 93-96 8082749-6 1994 We conclude that retinoic acid induces stabilization of wild-type p53 in NSCLC cells by a post-translational mechanism. Tretinoin 17-30 P53 Homo sapiens 66-69 8082749-7 1994 Furthermore, increases in expression of p53 were not responsible for the retinoic acid-induced transient inhibition of growth of NSCLC cells, since the growth of H358 p53-null cells also was inhibited by retinoic acid. Tretinoin 204-217 P53 Homo sapiens 167-170 8036011-3 1994 We have studied the capacity of hydrogen peroxide plus ferric chloride (FeCl3) to induce base pair changes in the hotspot codons 248 and 249 of the p53 tumor suppressor gene in human fibroblasts. Hydrogen Peroxide 32-49 P53 Homo sapiens 148-151 8036011-7 1994 It is evident that H2O2/FeCl3 possesses essentially the same mutagenic specificity for codons 249 and 250 of p53 as bulky carcinogens such as aflatoxin B1, benzo(a)pyrene or heterocyclic amines. Hydrogen Peroxide 19-23 P53 Homo sapiens 109-112 7882774-1 1994 Quantitative analysis of p53 protein expression was performed on paraffin-embedded tissues from 55 smooth muscle tumors of the gastrointestinal tract by using immunofluorescence and flow cytometry. Paraffin 65-73 P53 Homo sapiens 25-28 8037710-6 1994 Nevertheless nuclear p53 accumulation is at much higher extent, whereas 32P-orthophosphate labelling, followed by immunoprecipitation, demonstrates a decrease of phosphorylation of both cytoplasmic and nuclear p53. Phosphates 76-90 P53 Homo sapiens 210-213 8034027-11 1994 In this study, we demonstrate that conjugates of p53 generated in the presence of purified, E1, E2, E6-AP, E6, ubiquitin and ATP, are specifically recognized by the 26S protease complex and degraded. Adenosine Triphosphate 125-128 P53 Homo sapiens 49-52 7937752-3 1994 Using conformational energy analysis based on ECEPP (Empirical Conformational Energy for Peptides Program), we have determined the low-energy three-dimensional structures for this dodecapeptide sequence for the human wild-type p53 protein and three environmentally induced, cancer-related mutant p53 proteins with His-151, Ser-152, and Val-154, respectively. Histidine 314-317 P53 Homo sapiens 227-230 7937752-3 1994 Using conformational energy analysis based on ECEPP (Empirical Conformational Energy for Peptides Program), we have determined the low-energy three-dimensional structures for this dodecapeptide sequence for the human wild-type p53 protein and three environmentally induced, cancer-related mutant p53 proteins with His-151, Ser-152, and Val-154, respectively. Serine 323-326 P53 Homo sapiens 227-230 7833367-5 1994 [3H]Thymidine incorporation assays showed that the recombinant adenoviruses were capable of inhibiting DNA synthesis in a p53-specific, dose-dependent fashion. Tritium 1-3 P53 Homo sapiens 122-125 21559604-2 1994 Positive staining for p53 protein was detected in 44 of 71 (62%) of these tumors on paraffin-embedded tissue, even in dysplastic areas. Paraffin 84-92 P53 Homo sapiens 22-25 8065358-4 1994 Here we show that hypoxia and heat, agents that induce cellular stress primarily by inhibiting oxygen-dependent metabolism and denaturing proteins, respectively, also cause an increase in p53 protein levels. Oxygen 95-101 P53 Homo sapiens 188-191 8062826-1 1994 In an effort to correlate the biological activity of the p53 protein with its conformation, we analysed 14 p53 mutants representative of the most frequently observed protein alterations in human cancers, at codons 175, 248 and 273 (22% of all mutations thus far reported), all three of which contained a CpG dinucleotide. cytidylyl-3'-5'-guanosine 304-320 P53 Homo sapiens 57-60 8062826-7 1994 All these results suggest that the occurrence of a mutation is dependent on two criteria: (i) the mutability of a given codon, such as those containing a CpG dinucleotide; (ii) the resulting amino acids, eventually leading to synthesis of a p53 conferring a growth advantage on the cell. cytidylyl-3'-5'-guanosine 154-170 P53 Homo sapiens 241-244 7928628-0 1994 Nuclear accumulation of p53 protein correlates with mutations in the p53 gene on archival paraffin-embedded tissues of human breast cancer. Paraffin 90-98 P53 Homo sapiens 24-27 7928628-0 1994 Nuclear accumulation of p53 protein correlates with mutations in the p53 gene on archival paraffin-embedded tissues of human breast cancer. Paraffin 90-98 P53 Homo sapiens 69-72 7928628-8 1994 We conclude that the immunohistochemical detection of nuclear p53 protein accumulation is highly associated with p53 gene mutations in archival paraffin-embedded tissues, and that this method is useful for rapid screening of p53 abnormalities. Paraffin 144-152 P53 Homo sapiens 62-65 8033090-6 1994 Expression of a dominant-negative mutant of p53 (codon 143, Val to Ala) in transfectants of the radiosensitive human ovarian cell line A2780 abrogates the radiation-induced G1 arrest. Alanine 67-70 P53 Homo sapiens 44-47 8055938-1 1994 Dimerization of p53 is required for high-affinity DNA binding and cysteine oxidation inhibits p53 DNA binding. Cysteine 66-74 P53 Homo sapiens 94-97 8055938-8 1994 Further characterization of the purified p53 revealed that the protein possesses highly reactive cysteine residues. Cysteine 97-105 P53 Homo sapiens 41-44 8055938-9 1994 We show that intrachain disulfide bonds form within the purified p53 molecules during storage in the absence of reducing agent. Disulfides 24-33 P53 Homo sapiens 65-68 8055938-10 1994 Zn2+ binding to p53 protect sulfhydryl groups from oxidation. Zinc 0-4 P53 Homo sapiens 16-19 8055938-12 1994 The oxidation of the p53 cysteine residues was also observed for nuclear p53 in baculovirus-infected insect cells. Cysteine 25-33 P53 Homo sapiens 21-24 8055938-12 1994 The oxidation of the p53 cysteine residues was also observed for nuclear p53 in baculovirus-infected insect cells. Cysteine 25-33 P53 Homo sapiens 73-76 8055938-13 1994 The redox status of the nuclear p53 regulates its DNA-binding activity in vitro confirming the essential role of the reduced state of cysteine residues in p53 for detectable DNA-binding activity. Cysteine 134-142 P53 Homo sapiens 32-35 8055938-13 1994 The redox status of the nuclear p53 regulates its DNA-binding activity in vitro confirming the essential role of the reduced state of cysteine residues in p53 for detectable DNA-binding activity. Cysteine 134-142 P53 Homo sapiens 155-158 8207805-9 1994 In the ACH-2 cell line, which is now demonstrated to contain an endogenous mutant form of p53 (amino acid 248, Arg to Gln), additional mutant p53 proteins did not alter HIV-1 replication. Arginine 111-114 P53 Homo sapiens 90-93 7913577-10 1994 Both p53 protein and p185 antibodies work well on routine, formalin-fixed, paraffin-embedded tissue and are easily used in routine diagnostic procedures. Paraffin 75-83 P53 Homo sapiens 5-8 8021299-10 1994 We show that a portion of both hsp70 and p53 indeed are present within the centrosome in Hela, COS, and 3T3 cells. carbonyl sulfide 95-98 P53 Homo sapiens 41-44 7931842-4 1994 We examined 62 endoscopic oesophageal biopsies and 36 oesophageal resections for p53 overexpression using the monoclonal antibody DO-7 on paraffin-embedded tissue. Paraffin 138-146 P53 Homo sapiens 81-84 7805554-1 1994 The monoclonal antibody to p53 and a rapid immunohistochemical method were used in this study to detect p53 expression in 50 paraffin-embedded breast cancers and 7 benign hyperplastic diseases of breast. Paraffin 125-133 P53 Homo sapiens 104-107 8208536-13 1994 In contrast, the p53 in cell lines with either homozygous 175His or 248His p53 mutations, were unable either to transactivate or bind to the p53 response element. 175his 58-64 P53 Homo sapiens 17-20 8012775-2 1994 PATIENTS AND METHODS: The immunohistochemical status of the p53 protein in 28 pT1 primary bladder cancers was determined on frozen tissue and archival paraffin block sections using three primary antibodies (CM-1, PAB1801 and D07). Paraffin 151-159 P53 Homo sapiens 60-63 8200229-3 1994 METHODS: IgG1 monoclonal antibody to human p53 protein (PAb 1801) was used to detect p53 in formalin-fixed, paraffin-embedded archival tumors resected from 84 patients with tumor limited to the bowel wall. Paraffin 108-116 P53 Homo sapiens 85-88 8183576-4 1994 Here we report the novel observation that human p53 protein can bind ATP and exhibits an intrinsic ATP stimulated DNA strand reassociation activity. Adenosine Triphosphate 69-72 P53 Homo sapiens 48-51 8183576-4 1994 Here we report the novel observation that human p53 protein can bind ATP and exhibits an intrinsic ATP stimulated DNA strand reassociation activity. Adenosine Triphosphate 99-102 P53 Homo sapiens 48-51 7926727-5 1994 Rather, the hydrophobic amino acid residues Leu-22 and Trp-23 of human p53 are both required for trans-activation activity, binding to the adenovirus E1B 55-kD protein and the human mdm-2-p53 protein in vitro. Tryptophan 55-58 P53 Homo sapiens 71-74 7926727-5 1994 Rather, the hydrophobic amino acid residues Leu-22 and Trp-23 of human p53 are both required for trans-activation activity, binding to the adenovirus E1B 55-kD protein and the human mdm-2-p53 protein in vitro. Tryptophan 55-58 P53 Homo sapiens 188-191 8187062-0 1994 Up-regulation of a mutant form of p53 by doxorubicin in human squamous carcinoma cells. Doxorubicin 41-52 P53 Homo sapiens 34-37 8187062-2 1994 The cells carry only a mutated form of the p53 gene, the G-->A mutation at codon 273 which results in an arginine to histidine substitution (mp53). Arginine 108-116 P53 Homo sapiens 43-46 8187062-2 1994 The cells carry only a mutated form of the p53 gene, the G-->A mutation at codon 273 which results in an arginine to histidine substitution (mp53). Histidine 120-129 P53 Homo sapiens 43-46 8196660-2 1994 We investigated the methylation status of the CpG dinucleotide at codon 248 in exon 7 of the p53 gene because this codon is a hot spot for inactivating mutations in the germ line and in most human somatic tissues examined. cytidylyl-3'-5'-guanosine 46-62 P53 Homo sapiens 93-96 7808790-3 1994 At present, our aim was, firstly, to see which were the best technical conditions for detection of p53 in the available paraffin-embedded tumor specimens, using several antibodies, specific for various epitopes; secondly, to investigate if some relation might exist between this expression and the histological features of these tumors. Paraffin 120-128 P53 Homo sapiens 99-102 8012776-4 1994 p53 expression was determined by immuno-histochemistry on paraffin embedded sections and flow cytometry was performed on cell suspensions derived from the same blocks. Paraffin 58-66 P53 Homo sapiens 0-3 8151752-9 1994 Consistent with this hypothesis, we detected a significant increase in p53 levels upon dexamethasone-induced repression of papillomavirus E6-E7 oncogene expression. Dexamethasone 87-100 P53 Homo sapiens 71-74 8133533-4 1994 METHODS: The expression of Bcl-2 and p53 was detected by immunohistochemistry on paraffin-embedded sections from 283 node-negative resectable breast cancers treated with local-regional therapy alone until relapse. Paraffin 81-89 P53 Homo sapiens 37-40 8174105-4 1994 We report here that p53-deficient hepatoma cells (Hep3B) transfected with mutant p53-249ser (codon 249 Arg-->Ser) acquire a new phenotype with an increased in vitro survival and mitotic activity. Arginine 103-106 P53 Homo sapiens 20-23 8152811-4 1994 We therefore introduced the pC53-SCX3 143 (Val-Ala) p53 mutation into a non tumorigenic adenoma derived cell line, AA/C1, which contained a truncating APC mutation, activating K-ras mutation but was wild-type for the p53 protein. Alanine 47-50 P53 Homo sapiens 52-55 8174105-4 1994 We report here that p53-deficient hepatoma cells (Hep3B) transfected with mutant p53-249ser (codon 249 Arg-->Ser) acquire a new phenotype with an increased in vitro survival and mitotic activity. Arginine 103-106 P53 Homo sapiens 81-84 8174105-4 1994 We report here that p53-deficient hepatoma cells (Hep3B) transfected with mutant p53-249ser (codon 249 Arg-->Ser) acquire a new phenotype with an increased in vitro survival and mitotic activity. Serine 112-115 P53 Homo sapiens 20-23 8174105-4 1994 We report here that p53-deficient hepatoma cells (Hep3B) transfected with mutant p53-249ser (codon 249 Arg-->Ser) acquire a new phenotype with an increased in vitro survival and mitotic activity. Serine 112-115 P53 Homo sapiens 81-84 7909221-5 1994 Positive staining for both p53 and HER-2/neu in paraffin-embedded tissues indicates an underlying genetic abnormality: point mutations in the p53 gene and amplification of the HER-2/neu gene. Paraffin 48-56 P53 Homo sapiens 27-30 8043159-9 1994 Since p53 (PAb 1801) expression can withstand formalin fixation and pepsin treatment of paraffin-embedded tissues, flow cytometric analysis of archival specimens is feasible, and clinical correlations such as these may be carried out in retrospective studies of other tumors. Paraffin 88-96 P53 Homo sapiens 6-9 8178805-5 1994 In addition, single-strand conformation polymorphism analysis and PCR-direct sequencing of BC cells revealed a point mutation at codon 203 of the p53 gene, GTG to GAG (Val to Glu), and loss of the normal allele. Glutamic Acid 175-178 P53 Homo sapiens 146-149 7909221-5 1994 Positive staining for both p53 and HER-2/neu in paraffin-embedded tissues indicates an underlying genetic abnormality: point mutations in the p53 gene and amplification of the HER-2/neu gene. Paraffin 48-56 P53 Homo sapiens 142-145 8027368-8 1994 Fragments of the p53 gene were successfully amplified up to 408 base pairs in water boiled extracts, up to 647 in Chelex boiled preparates, and up to 984 in proteinase K digested and proteinase K digested-Chelex boiled samples, although with decreased sensitivity in the last case. Water 78-83 P53 Homo sapiens 17-20 8168507-7 1994 Using metal affinity chromatography, we have established that pure p53 binds the immobilised divalent ions Zn2+, Ni2+ and Co2+ with high affinity. Metals 6-11 P53 Homo sapiens 67-70 8168507-7 1994 Using metal affinity chromatography, we have established that pure p53 binds the immobilised divalent ions Zn2+, Ni2+ and Co2+ with high affinity. Zinc 107-111 P53 Homo sapiens 67-70 8168507-7 1994 Using metal affinity chromatography, we have established that pure p53 binds the immobilised divalent ions Zn2+, Ni2+ and Co2+ with high affinity. Nickel(2+) 113-117 P53 Homo sapiens 67-70 7908608-10 1994 The p53 arginine allele was found to be more common in Caucasians (0.71) than African-Americans (0.50). Arginine 8-16 P53 Homo sapiens 4-7 8027368-8 1994 Fragments of the p53 gene were successfully amplified up to 408 base pairs in water boiled extracts, up to 647 in Chelex boiled preparates, and up to 984 in proteinase K digested and proteinase K digested-Chelex boiled samples, although with decreased sensitivity in the last case. chelex 114-120 P53 Homo sapiens 17-20 8141761-0 1994 Increased salt concentration reversibly destabilizes p53 quaternary structure and sequence-specific DNA binding. Salts 10-14 P53 Homo sapiens 53-56 8051396-6 1994 Sequencing of polymerase chain reaction products showed that all mutations in exon 5 were clustered at codon 166 and were T/A transversions resulting in an amino acid change from serine to threonine, identifying a new hot-spot for point mutations in the p53 gene. Serine 179-185 P53 Homo sapiens 254-257 8051396-6 1994 Sequencing of polymerase chain reaction products showed that all mutations in exon 5 were clustered at codon 166 and were T/A transversions resulting in an amino acid change from serine to threonine, identifying a new hot-spot for point mutations in the p53 gene. Threonine 189-198 P53 Homo sapiens 254-257 8141761-4 1994 We conclude that high salt can reversibly destabilize the quaternary structure of p53 that is most efficient for sequence-specific DNA binding. Salts 22-26 P53 Homo sapiens 82-85 8119988-6 1994 Moreover, an oligonucleotide containing Rb promoter sequences between -63 and -88 was sufficient to confer stimulation by p53 when inserted upstream from a minimal heterologous promoter. Oligonucleotides 13-28 P53 Homo sapiens 122-125 8119773-5 1994 The growth kinetics of wt-p53 transfectants were suppressed compared with those of parental cells, vector transfectants, or mut-p53 transfectants, as assayed by growth-curve measurements and 3H-thymidine incorporation; however, RNA dot blot and Western blot analyses demonstrated that wt-p53 and mut-p53 transfectants expressed higher amounts of TGF-beta 1 and TGF-beta 2 mRNA and intracellular TGF-beta isoform proteins, respectively, than parental cells. Tritium 191-193 P53 Homo sapiens 26-29 8156496-3 1994 METHODS: The status of the p53 gene was studied by immunohistochemistry of formalin-fixed paraffin-embedded biopsy samples from 72 patients with atypical endometrial hyperplasia or endometrioid carcinoma who underwent hysterectomy immediately after biopsy and from 5 patients with benign endometria. Paraffin 90-98 P53 Homo sapiens 27-30 8119988-7 1994 Gel mobility shift analysis was used to demonstrate that p53 can bind to a sequence within the -63 to -88 oligonucleotide with homology to a p53 binding site. Oligonucleotides 106-121 P53 Homo sapiens 57-60 8119988-7 1994 Gel mobility shift analysis was used to demonstrate that p53 can bind to a sequence within the -63 to -88 oligonucleotide with homology to a p53 binding site.

Paraffin 38-46 P53 Homo sapiens 34-37 8123475-7 1994 Antisense oligonucleotides to p53 were used to suppress p53 protein expression in blasts with non-autocrine growth and also the factor-dependent human erythroleukaemia cell line TF-1. Oligonucleotides 10-26 P53 Homo sapiens 30-33 8123475-7 1994 Antisense oligonucleotides to p53 were used to suppress p53 protein expression in blasts with non-autocrine growth and also the factor-dependent human erythroleukaemia cell line TF-1. Oligonucleotides 10-26 P53 Homo sapiens 56-59 8018565-1 1994 Activation of the protein kinase C signaling pathway by tumor-promoting phorbol esters, such as 4 beta-phorbol 12-myristate 13-acetate (PMA), induced a decrease in the level of p53 mRNA in several serum-starved human cell lines. Tetradecanoylphorbol Acetate 96-134 P53 Homo sapiens 177-180 8018565-1 1994 Activation of the protein kinase C signaling pathway by tumor-promoting phorbol esters, such as 4 beta-phorbol 12-myristate 13-acetate (PMA), induced a decrease in the level of p53 mRNA in several serum-starved human cell lines. Tetradecanoylphorbol Acetate 136-139 P53 Homo sapiens 177-180 8018565-7 1994 PMA induced a similar transient decrease in the level of p53 protein in the A549 cell line. Tetradecanoylphorbol Acetate 0-3 P53 Homo sapiens 57-60 8162251-3 1994 We have developed a method utilizing polymerase chain reaction (PCR) for the direct analysis of p53 mutation by single-strand conformation polymorphism (SSCP) and by direct DNA sequencing of the p53 gene using a single 10-microns paraffin-embedded tissue section. Paraffin 230-238 P53 Homo sapiens 195-198 8162251-4 1994 We applied this method to screen for p53 gene mutations in exons 5-8 in human gliomas utilizing paraffin-embedded tissues. Paraffin 96-104 P53 Homo sapiens 37-40 8108142-5 1994 Mutant p53 specifically increases TPA induction of VEGF without affecting the expression of other TPA inducible genes. Tetradecanoylphorbol Acetate 34-37 P53 Homo sapiens 7-10 8108142-6 1994 TPA dependent VEGF expression is also enhanced by human p53 mutated at amino acid 175. Tetradecanoylphorbol Acetate 0-3 P53 Homo sapiens 56-59 21607363-2 1994 We examined the immunohistochemical expression of p53 in 40 paraffin-embedded samples obtained from colon carcinomas using the two new MAbs DO-1 and DO-7. Paraffin 60-68 P53 Homo sapiens 50-53 8305445-0 1994 DNA recognition by alternate strand triple helix formation: affinities of oligonucleotides for a site in the human p53 gene. Oligonucleotides 74-90 P53 Homo sapiens 115-118 8116572-1 1994 The authors had previously reported that the accumulation of p53 is clearly demonstrable in microwave-fixed, paraffin-embedded sections of colorectal carcinomas. Paraffin 109-117 P53 Homo sapiens 61-64 8311654-4 1994 Positive nuclear p53 immunoreactivity was detected in 37% of paraffin-embedded primary tumors (21.8% in the Japanese group, 52.6% in the American group) and in 50% of xenotransplanted carcinoma cell lines. Paraffin 61-69 P53 Homo sapiens 17-20 8311654-8 1994 The fact that more than half of the ethanol-fixed fine-needle aspirates were positive for p53 suggests that this type of immunostain may be of potential diagnostic significance.

Paraffin 34-42 P53 Homo sapiens 0-3 8106638-13 1994 As p53 protein is a regulator of guanine nucleotide synthesis, the loss of normal inhibitory regulation by the p53 mutation would serve to increase the availability of GTP for the transduction of signals essential for increased cell growth and hormone expression in the adrenal tumors. Guanosine Triphosphate 168-171 P53 Homo sapiens 3-6 8106638-13 1994 As p53 protein is a regulator of guanine nucleotide synthesis, the loss of normal inhibitory regulation by the p53 mutation would serve to increase the availability of GTP for the transduction of signals essential for increased cell growth and hormone expression in the adrenal tumors. Guanosine Triphosphate 168-171 P53 Homo sapiens 111-114 8008749-4 1994 We investigated expression of p53 in formalin-fixed, paraffin-embedded archival specimens of 40 CCs (22 autopsy cases and 18 surgical cases) by immunohistochemistry using four antibodies (PAb1801, DO-7, BP53-12, CM1). Paraffin 53-61 P53 Homo sapiens 30-33 8008749-10 1994 These results shows that a pretreatment of tissue sections by microwave oven heating is a very good method for demonstrating p53 protein in formalin-fixed, paraffin-embedded archival materials and that DO-7, BP53-12, and CM1 are useful antibodies for detection of p53 in formalin-fixed, paraffin-embedded archival materials.

Paraffin 35-43 P53 Homo sapiens 72-75 7894617-5 1994 The mutation in another case was a nonsense G:C-A:T transition at codon 52 (TGG-TGA; Trp-stop codon) leading to a truncated p53 peptide. Tryptophan 85-88 P53 Homo sapiens 124-127 8247533-6 1993 Agents that produced double-strand breaks in DNA and/or inhibition of transcription caused an induction of p53 in the absence of radiation in control cells but not in ataxia-telangiectasia, but inhibitors of cell cycle progression such as mimosine and aphidicolin led to an increase in p53 in both cell types in the absence of radiation. Mimosine 239-247 P53 Homo sapiens 107-110 7787250-9 1994 The T24 cell line was found to contain a novel p53 mutant having an in-frame deletion of tyrosine 126.

Paraffin 0-8 P53 Homo sapiens 17-20 8252480-5 1993 METHODS: Tumor tissues of 156 patients with primary invasive breast cancer were analyzed immunohistochemically for the presence of p53 protein in paraffin-embedded material. Paraffin 146-154 P53 Homo sapiens 131-134 8117626-1 1993 In order to clarify the role of the p53 tumor suppressor gene in controlling growth and differentiation of human epithelial cells, we transfected a wild-type p53 complementary DNA, driven by a dexamethasone-inducible mouse mammary tumor virus promoter, into SqCC/Y1 human head-and-neck squamous carcinoma cells. Dexamethasone 193-206 P53 Homo sapiens 36-39 8117626-2 1993 When treated with dexamethasone, 2 of 8 independent clones that contained integrated vector sequences expressed wild-type p53-specific mRNA as well as nuclear p53 protein.

Dexamethasone 18-31 P53 Homo sapiens 159-162 8276239-5 1993 Because the fragment does not contain the cdc2 phosphorylation site at Ser-315, we conclude that the the site-specific DNA-binding domain of p53 spans the central region of the protein.

Tamoxifen 38-47 P53 Homo sapiens 173-176 7901994-13 1993 We conclude that the immunohistochemical detection of p53 nuclear accumulation in formalin-fixed, paraffin-embedded tissue is highly associated with mutations in the p53 gene; this association has now been demonstrated in a large number of tumors.

Metals 78-83 P53 Homo sapiens 38-41 8221671-7 1993 Furthermore, metal ions may regulate binding of p53 to DNA by modulating its conformation. Metals 13-18 P53 Homo sapiens 48-51 8221663-2 1993 Mutations of the p53 gene were found in six of seven ES cell lines: a missense mutation of TGC (Cys)-->TAC (Try) at codon 141 in one, a missense mutation of CGT (Arg)-->TGT (Cys) at codon 273 in one, a missense mutation of TGC (Cys)-->TTC (Phe) at codon 176 in three, and one base deletion of CGC-->CG at codon 283 in one. Cysteine 96-99 P53 Homo sapiens 17-20 8221663-3 1993 Further analysis of 14 ES and related primary tumors showed mutations of the p53 gene in only two: one base insertion of CCG-->CCCG at codon 152 in one and a missense mutation of GGC (Gly)-->GTC (Val) at codon 154 in the other. Glycine 187-190 P53 Homo sapiens 77-80 7692889-1 1993 OBJECTIVES: To improve the detection of p53 protein in formalin-fixed, paraffin-embedded head and neck tumor tissues.

Cysteine 180-183 P53 Homo sapiens 17-20 8221663-2 1993 Mutations of the p53 gene were found in six of seven ES cell lines: a missense mutation of TGC (Cys)-->TAC (Try) at codon 141 in one, a missense mutation of CGT (Arg)-->TGT (Cys) at codon 273 in one, a missense mutation of TGC (Cys)-->TTC (Phe) at codon 176 in three, and one base deletion of CGC-->CG at codon 283 in one. Cysteine 180-183 P53 Homo sapiens 17-20 8414520-4 1993 We show that p53 binds to a target oligonucleotide as a protein homodimer and that p53 dimerisation is required for detectable DNA binding. Oligonucleotides 35-50 P53 Homo sapiens 13-16 21573436-4 1993 Expression of p53 protein and P-170 glycoprotein was detected by immunohistochemistry using the PAb1801 and C219 monoclonal antibody respectively, on sections from paraffin-embedded tumor biopsies.

Arginine 105-108 P53 Homo sapiens 22-25 21573446-8 1993 The point mutation of p53 gene was found at codon 181 contained C to T transversions (Amino acid switch: Arg --> Cys) in ES-4 esophageal cancer. Cysteine 116-119 P53 Homo sapiens 22-25 21573446-9 1993 The accumulations of p53 proteins were also associated with the down regulated intra-cellular-cAMP induced by high concentrations of EGF.

Oligonucleotides 48-64 P53 Homo sapiens 34-37 8231251-5 1993 We found that the introduction of p53 antisense oligonucleotides can specifically inhibit the translation of the p53 mRNA. Oligonucleotides 48-64 P53 Homo sapiens 113-116 8402615-2 1993 Here we show that both conformation and sequence-specific DNA binding of p53 translated in vitro can be modulated by metal chelators and oxidizing agents.

Histidine 41-44 P53 Homo sapiens 37-40 8415687-1 1993 We report that p53her, a chimeric protein consisting of the complete human wild-type p53 and the human estrogen receptor hormone-binding domain, strongly suppresses proliferation and induces characteristic morphological changes in Saos-2 human osteosarcoma cells when induced by 17 beta-estradiol. Estradiol 282-296 P53 Homo sapiens 15-18 8415687-3 1993 However, coexpression of p53her and oncoprotein MDM-2, which associates with and presumably inactivates p53, results in suppression of p53her-mediated transactivation in the absence, but not the presence, of estradiol. Estradiol 208-217 P53 Homo sapiens 25-28 8415687-4 1993 Similarly, p53her induces expression of an endogenous MDM-2 transcript only in the presence of estradiol.

Cisplatin 138-147 P53 Homo sapiens 17-20 8406999-2 1993 The majority of the independent cisplatin-resistant clones isolated by a single selection with cisplatin from the ovarian tumour cell line A2780 showed increased levels of p53 protein compared to the parental cell line. Cisplatin 32-41 P53 Homo sapiens 172-175 8406999-2 1993 The majority of the independent cisplatin-resistant clones isolated by a single selection with cisplatin from the ovarian tumour cell line A2780 showed increased levels of p53 protein compared to the parental cell line. Cisplatin 95-104 P53 Homo sapiens 172-175 8406999-3 1993 Elevated p53 protein levels were also observed in cisplatin-resistant ovarian human tumour lines isolated after multiple exposures to cisplatin (A2780/cp70 and OVIP/DDP). Cisplatin 50-59 P53 Homo sapiens 9-12 8406999-3 1993 Elevated p53 protein levels were also observed in cisplatin-resistant ovarian human tumour lines isolated after multiple exposures to cisplatin (A2780/cp70 and OVIP/DDP). Cisplatin 134-143 P53 Homo sapiens 9-12 8406999-8 1993 Transfection of a mutant p53 gene construct (containing a mutation at codon 143, val to ala) into the A2780/cp70 resistant cells conferred a significantly increased sensitivity to cisplatin, suggesting that p53 is a direct determinant of cisplatin resistance in these cells.

Cisplatin 238-247 P53 Homo sapiens 207-210 15335855-6 1993 Furthermore, crosslinking of the chimeras resulted in tyrosine phosphorylation of the Ig-alpha and Tg-beta tails and their association with the tyrosine kinases PTK72, p53/56(lyn) and p59(fyn). Tyrosine 54-62 P53 Homo sapiens 168-171 7508232-3 1993 Using streptavidin-biotin complex method, p53 was identified in 33% of dysplastic squamous lesions, 50% of squamous cell carcinomas (SCCs) and 36% of basal cell carcinomas (BCCs) on frozen section, whereas 25% of dysplastic squamous lesions, 40% of SCCs, and 32% of BCCs showed p53 positivity on paraffin-embedded sections.

Alcohols 133-140 P53 Homo sapiens 14-17 11706422-4 1993 25% (3/12) of p53-positive neoplasms and 71.4% (20/28) of p53-negative neoplasms were found in patients who had been exposed to both alcohol and tobacco. Alcohols 133-140 P53 Homo sapiens 58-61 11706422-5 1993 A similar negative association with p53 reactivity was also found when either tobacco or alcohol were used in isolation. Alcohols 89-96 P53 Homo sapiens 36-39 11706422-6 1993 The results contrast with previous observations in head/neck and oral carcinomas and indicate that the association of alcohol/tobacco and p53 expression remains open to question. Alcohols 118-125 P53 Homo sapiens 138-141 8375929-4 1993 The IGF-I-induced DNA synthesis coincided with an elevated level of phosphorylation of p53 on tyrosine and an alteration in the subcellular distribution of the protein from the nucleus to the cytoplasm. Tyrosine 94-102 P53 Homo sapiens 87-90 8221631-4 1993 The p53-hsc73 protein complexes dissociate with the addition of ATP, indicating that the dissociation is dependent upon the ATP-hydrolysis. Adenosine Triphosphate 64-67 P53 Homo sapiens 4-7 8221631-4 1993 The p53-hsc73 protein complexes dissociate with the addition of ATP, indicating that the dissociation is dependent upon the ATP-hydrolysis. Adenosine Triphosphate 124-127 P53 Homo sapiens 4-7 8283348-6 1993 Overexpression of the p53 protein was found by immunostaining of sections from formalin-fixed, paraffin-embedded material in 55 per cent (51/92) of the tumours.

Serine 102-108 P53 Homo sapiens 49-52 8397412-6 1993 Since the latter mutations are not observed in HCC it follows that both mutability on the DNA level and altered function of the mutant serine 249 p53 protein are responsible for the observed mutational hot spot in p53 in HCC from AFB1-contaminated areas. Serine 135-141 P53 Homo sapiens 146-149 8397412-6 1993 Since the latter mutations are not observed in HCC it follows that both mutability on the DNA level and altered function of the mutant serine 249 p53 protein are responsible for the observed mutational hot spot in p53 in HCC from AFB1-contaminated areas. Serine 135-141 P53 Homo sapiens 214-217 8352280-8 1993 These findings indicate that the p53 variant with a serine at codon 47 should be considered as a rare germ-line polymorphism that does not alter the growth-suppression activity of p53.

Dexmedetomidine 30-33 P53 Homo sapiens 123-126 33275947-9 2021 To eliminate the pro-apoptotic effect of Dex while retaining its anti-apoptosis action, we screened miRNA-151-3p to target DAPK-1 and p53. Dexmedetomidine 41-44 P53 Homo sapiens 134-137 33075425-2 2021 However, 2"-fluoro-4"-seleno-ara-C (F-Se-Ara-C), a new generation of cytarabine (Ara-C) analogs, exhibited potent antitumor activity against the p53-deficient prostate cancer cell line PC-3. 2'-Fluoro-4'-seleno-ara-C 9-34 P53 Homo sapiens 145-148 33275947-10 2021 Transfection with miRNA-151-3p mimics suppressed DAPK-1 and TP53 expression induced by Dex and increased Nrf-2 and SOD expression.

Hydroxyurea 41-52 P53 Homo sapiens 195-198 33137455-1 2021 The manner in which p53 maintains redox homeostasis and the means by which two key metabolic elements, glucose and glutamine, contribute to p53-dependent redox stability remain unclear. Glutamine 115-124 P53 Homo sapiens 140-143 33137455-5 2021 However, in glucose-deprived and ROS-prone conditions, HN3R-B, the subclone with the original p53 increased the utilization of glutamine by GLS2, thereby maintaining redox homeostasis and ATP.

Sodium orthovanadate 0-20 P53 Homo sapiens 30-33 20048077-1 2010 Sodium orthovanadate (vanadate) inhibits the DNA-binding activity of p53, but its precise effects on p53 function have not been examined. Sodium orthovanadate 0-20 P53 Homo sapiens 69-72 21460857-4 2011 In addition, ABT737 treatment dephosphorylates (and hence likewise inhibits) p53, glycogen synthase kinase-3 and Akt. ABT-737 13-19 P53 Homo sapiens 77-80 20122668-0 2010 Influence of chemoresistance and p53 status on fluoro-2-deoxy-D-glucose incorporation in cancer. fluoro-2-deoxy-d-glucose 47-71 P53 Homo sapiens 33-36 21892957-8 2011 An amino acid polymorphism in the ZANK region is identified in ZEBRA from tumor cell lines including Akata that could alter binding of Akata ZEBRA to the p53 tumor suppressor and other ankyrin binding protein, and a novel model of antagonistic binding interactions between ZANK and the DNA binding regions of ZEBRA is suggested that may be explored in further biochemical and molecular biological models of viral replication. akata 101-106 P53 Homo sapiens 154-157 20023923-1 2009 Octahedral ruthenium complexes, capable of photodynamic singlet oxygen production at near 100% efficiency, were shown to cause light-dependent covalent crosslinking of p53 and PCNA subunits in mammalian cells and cell lysates. Singlet Oxygen 56-70 P53 Homo sapiens 168-171 20023923-2 2009 Azide, a singlet oxygen quencher, greatly reduced the p53 photocrosslinking, consistent with the idea that singlet oxygen is the reactive oxygen species involved in p53 photocrosslinking. Singlet Oxygen 9-23 P53 Homo sapiens 54-57 20023923-2 2009 Azide, a singlet oxygen quencher, greatly reduced the p53 photocrosslinking, consistent with the idea that singlet oxygen is the reactive oxygen species involved in p53 photocrosslinking. Singlet Oxygen 107-121 P53 Homo sapiens 54-57 20023923-2 2009 Azide, a singlet oxygen quencher, greatly reduced the p53 photocrosslinking, consistent with the idea that singlet oxygen is the reactive oxygen species involved in p53 photocrosslinking. Singlet Oxygen 107-121 P53 Homo sapiens 165-168 21708241-9 2011 Subamolide A increased Bax/Bcl-2 ratios, the amount of cytochrome c released from the mitochondria, caspase-3 and PARP cleavage, activated p53 and ERK1/2 and ultimately led to apoptosis in NTUB1 cells. subamolide A 0-12 P53 Homo sapiens 139-142 19766654-6 2009 In fact, substitution of this Asn to Ala of CHC diminished its ability to interact with p53, leading to reduced activity to transactivate p53. Asparagine 30-33 P53 Homo sapiens 88-91 21708241-11 2011 CONCLUSIONS: The current study demonstrated that subamolide A triggered the mitochondria-dependent apoptotic pathways and p53 and ERK1/2 activation in the human urothelial carcinoma cell line NTUB1. subamolide A 49-61 P53 Homo sapiens 122-125 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 115-119 P53 Homo sapiens 64-67 19715480-5 2009 The H322J cells, with mutant (Arg248Gln) p53, showed NF-kappaB activation and IkappaB-alpha degradation after adeno-p53 expression + 2-ME treatment; however, these conditions separately did not activate NF-kappaB, rather caused accumulation of IkappaB-alpha. 2-Methoxyestradiol 133-137 P53 Homo sapiens 41-44 19715480-6 2009 In contrast, either adeno-p53 expression or 2-ME treatment induced NF-kappaB activation in the p53-deleted H1299 cells, but H460 cells, containing wt-p53, did not show NF-kappaB activation under any of these conditions. 2-Methoxyestradiol 44-48 P53 Homo sapiens 95-98 19715480-6 2009 In contrast, either adeno-p53 expression or 2-ME treatment induced NF-kappaB activation in the p53-deleted H1299 cells, but H460 cells, containing wt-p53, did not show NF-kappaB activation under any of these conditions. 2-Methoxyestradiol 44-48 P53 Homo sapiens 95-98 19715480-7 2009 This shows p53-dependent differential signaling to NF-kappaB by 2-ME. 2-Methoxyestradiol 64-68 P53 Homo sapiens 11-14 19715480-8 2009 Since NF-kappaB activation inhibits apoptosis and causes resistance to chemotherapy, our study suggests the need to distinguish p53 phenotypes of tumors for p53 gene and 2-ME therapy. 2-Methoxyestradiol 170-174 P53 Homo sapiens 128-131 19917243-2 2009 (2009) have identified the enzyme guanidinoacetate methyltransferase (GAMT) that regulates creatine metabolism as a p53 target involved in apoptosis, reactive oxygen species (ROS), and fatty acid metabolism. Creatine 91-99 P53 Homo sapiens 116-119 19917247-3 2009 Here we identify guanidinoacetate methyltransferase (GAMT), an enzyme involved in creatine synthesis, as a p53 target gene and a key downstream effector of adaptive response to nutrient stress. Creatine 82-90 P53 Homo sapiens 107-110 19917247-7 2009 The p53-->GAMT pathway represents a new link between cellular stress responses and processes of creatine synthesis and FAO, demonstrating a further role of p53 in cellular metabolism. Creatine 99-107 P53 Homo sapiens 4-7 19917247-7 2009 The p53-->GAMT pathway represents a new link between cellular stress responses and processes of creatine synthesis and FAO, demonstrating a further role of p53 in cellular metabolism. Creatine 99-107 P53 Homo sapiens 159-162 19838062-6 2009 Similarly, the gold-based TrxR inhibitor auranofin induced apoptosis related to oxidative stress, but independently of p53 and without apparent induction of the approximately 130 kDa form of TrxR1. Auranofin 41-50 P53 Homo sapiens 119-122 19656744-7 2009 DNA pull-down assays using a 7,8-dihydro-8-oxoguanine duplex oligonucleotide as a substrate found that RPS3 acted as a scaffold for the additional binding of MDM2 and p53, suggesting that RPS3 interacts with important proteins involved in maintaining genomic integrity. 7,8-dihydro-8-oxoguanine duplex oligonucleotide 29-76 P53 Homo sapiens 167-170 19646415-0 2009 NF-kappab facilitates oridonin-induced apoptosis and autophagy in HT1080 cells through a p53-mediated pathway. oridonin 22-30 P53 Homo sapiens 89-92 19646415-3 2009 In addition, treatment with oridonin caused an increase in NF-kappaB and p53 activities in a time-dependent manner. oridonin 28-36 P53 Homo sapiens 73-76 19646415-4 2009 Inhibition of NF-kappaB or p53 activation by its specific inhibitor PDTC or pifithrin-alpha respectively, significantly reduced both oridonin-induced apoptosis and autophagy accompanied by the decrease in Beclin 1 and LC3 levels. oridonin 133-141 P53 Homo sapiens 27-30 19646415-5 2009 Further experiments confirmed that oridonin-induced p53 activation was reduced by the NF-kappaB inhibitor whereas the activation of NF-kappaB was not affected by p53 inhibition. oridonin 35-43 P53 Homo sapiens 52-55 19646415-6 2009 Taken together, these results demonstrate that NF-kappaB promotes oridonin-induced apoptotic and autophagic cell death through regulating p53 activation in HT1080 cells. oridonin 66-74 P53 Homo sapiens 138-141 19706754-5 2009 We also found that the enhanced activation of JNK by 2-ME is partially regulated by p53, highlighting the relationship of JNK and autophagy to p53 signaling pathway. 2-Methoxyestradiol 53-57 P53 Homo sapiens 84-87 19706754-5 2009 We also found that the enhanced activation of JNK by 2-ME is partially regulated by p53, highlighting the relationship of JNK and autophagy to p53 signaling pathway. 2-Methoxyestradiol 53-57 P53 Homo sapiens 143-146 19706754-6 2009 Furthermore, we showed that 2-ME up-regulates damage-regulated autophagy modulator (DRAM), a p53 target gene, in Ewing sarcoma cells through a mechanism that involves JNK activation. 2-Methoxyestradiol 28-32 P53 Homo sapiens 93-96 19458022-5 2009 Clinical importance of the polymorphic variants was evaluated in multivariate models on 69 patients treated with taxane-platinum chemotherapy, with respect to TP53 status. taxane-platinum 113-128 P53 Homo sapiens 159-163 19524575-0 2009 In vitro recapitulating of TP53 mutagenesis in hepatocellular carcinoma associated with dietary aflatoxin B1 exposure. Aflatoxin B1 96-108 P53 Homo sapiens 27-31 19524575-9 2009 CONCLUSIONS: In this model system, AFB(1)-induced DNA adduction and mutagenesis recapitulate the unique mutational features of TP53 in AFB(1)-associated human HCC. Aflatoxin B1 35-41 P53 Homo sapiens 127-131 19421231-9 2009 Most BL patients with wild-type p53 tumors could therefore benefit from treatment with nutlin-3, after a careful determination of the latency pattern of EBV in infected patients. nutlin 3 87-95 P53 Homo sapiens 32-35 19597154-4 2009 Functional assays revealed a specific dinucleotide core combination within the CWWG motif of the p53RE to be the key factor that determines whether p53 transcriptionally activates or represses a target gene. Dinucleoside Phosphates 38-50 P53 Homo sapiens 97-100 19597154-4 2009 Functional assays revealed a specific dinucleotide core combination within the CWWG motif of the p53RE to be the key factor that determines whether p53 transcriptionally activates or represses a target gene. Dinucleoside Phosphates 38-50 P53 Homo sapiens 148-151 19723057-0 2009 Effects of 15-deoxy-delta 12, 14-prostaglandin J2 on the expression of p53 in MCF-7 cells. 15-deoxy-delta 12 11-28 P53 Homo sapiens 71-74 19558638-0 2009 Effect of hydroxyurea on the promoter occupancy profiles of tumor suppressor p53 and p73. Hydroxyurea 10-21 P53 Homo sapiens 77-80 19558638-4 2009 The goal of this study was to compare the promoter-binding activity of p53 and p73 at steady state and after genotoxic stress induced by hydroxyurea. Hydroxyurea 137-148 P53 Homo sapiens 71-74 19558638-7 2009 We also found that after hydroxyurea treatment, the p53-bound promoters were still bound by p73, but p73 became associated with additional promoters that that did not bind p53. Hydroxyurea 25-36 P53 Homo sapiens 52-55 19509161-0 2009 Restoration of p53 pathway by nutlin-3 induces cell cycle arrest and apoptosis in human rhabdomyosarcoma cells. nutlin 3 30-38 P53 Homo sapiens 15-18 19411846-10 2009 Surprisingly, blocking the transcriptional arm of p53, either via alpha-Amanitin or the p53-specific transcriptional inhibitor Pifithrin alpha, not only fails to inhibit, but greatly potentiates Nutlin-induced apoptosis. Alpha-Amanitin 66-80 P53 Homo sapiens 50-53 19411857-9 2009 Incubation with the phosphatase inhibitor okadaic acid produced more phosphorylation of CHK1 in UV-treated HPV16E6-expressing cells than in p53-H179Q-expressing cells suggesting that HPV16E6 may interfere with the recovery of coupled DNA replication at replication forks that are stalled at [6-4]pyrimidine-pyrimidone photoproducts and BPDE-DNA adducts. Okadaic Acid 42-54 P53 Homo sapiens 140-143 19567200-6 2009 The up-regulations of Bcl-xL and IAP by CpG DNA were not inhibited when blocking PI3K by specific inhibitor Ly294002, while the inhibition of p53 by CpG DNA could be blocked by Ly294002. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 177-185 P53 Homo sapiens 142-145 19475715-5 2009 However, pifithrin alfa (PFT-alpha), an inhibitor of p53, fails to rescue the cells from the cadmium-induced cell cycle arrest but prevents Bcl-xl down-regulation and loss of Deltapsi(m), which indicates that there is an involvement of p53 in apoptosis. pifithrin alfa 9-23 P53 Homo sapiens 53-56 19475715-5 2009 However, pifithrin alfa (PFT-alpha), an inhibitor of p53, fails to rescue the cells from the cadmium-induced cell cycle arrest but prevents Bcl-xl down-regulation and loss of Deltapsi(m), which indicates that there is an involvement of p53 in apoptosis. pifithrin alfa 9-23 P53 Homo sapiens 236-239 19323449-2 2009 Here we study the effect of modifications of a p53 N-terminal fragment on its binding to MDM2, using implicit-solvent MD and MM-GB/SA calculations. 2-chloro-10-(4'(N-beta-hydroxyethyl)piperazinyl-1')acetylphenothiazine 131-133 P53 Homo sapiens 47-50 19010591-4 2009 Subsequently, we found that PCL treatment abrogated glutathione antioxidant system and induced mitochondria to generate ROS accumulation, resulting in p38-p53 activation. pcl 28-31 P53 Homo sapiens 155-158 19010591-6 2009 In conclusion, these results indicate that PCL induces apoptosis and autophagy via a mitochondrial-mediated ROS-p38-p53 pathway. pcl 43-46 P53 Homo sapiens 116-119 19305157-0 2009 Diversity of DNA damage response of astrocytes and glioblastoma cell lines with various p53 status to treatment with etoposide and temozolomide.

Camptothecin 69-81 P53 Homo sapiens 36-39 19155291-0 2009 Limits to thymidylate synthase and TP53 genes as predictive determinants for fluoropyrimidine sensitivity and further evidence for RNA-based toxicity as a major influence. 2-fluoropyrimidine 77-93 P53 Homo sapiens 35-39 19208740-0 2009 p53 mutant human glioma cells are sensitive to UV-C-induced apoptosis due to impaired cyclobutane pyrimidine dimer removal. Cyclobutanes 86-97 P53 Homo sapiens 0-3 18765419-0 2009 The carcinogenic air pollutant 3-nitrobenzanthrone induces GC to TA transversion mutations in human p53 sequences. 3-nitrobenzanthrone 31-50 P53 Homo sapiens 100-103 19152081-3 2009 For the genetic changes closely related to etiology of liver cancer, the well-known cases include insertion and integration of the hepatitis B virus (HBV) DNA after infection, and mutations at site 249 of the tumor suppressor gene p53 induced by exposure to aflatoxin B1. Aflatoxin B1 258-270 P53 Homo sapiens 231-234 20371709-7 2010 Consistently, Sirtinol and Salermide, but not EX527, treatment resulted in the in vivo acetylation of the SIRT1/2 target p53 and SIRT2 target tubulin in MCF-7 cells, suggesting that EX527 is ineffective in inhibiting SIRT2 and that p53 mediates the cytotoxic function of Sirtinol and Salermide. sirtinol 14-22 P53 Homo sapiens 121-124 20371709-7 2010 Consistently, Sirtinol and Salermide, but not EX527, treatment resulted in the in vivo acetylation of the SIRT1/2 target p53 and SIRT2 target tubulin in MCF-7 cells, suggesting that EX527 is ineffective in inhibiting SIRT2 and that p53 mediates the cytotoxic function of Sirtinol and Salermide. sirtinol 14-22 P53 Homo sapiens 232-235 20075077-4 2010 Treatment with the genotoxic agents, doxorubicin or etoposide, induced Foxp3 expression in p53-positive carcinoma cells, but not in cells lacking p53 function. Etoposide 52-61 P53 Homo sapiens 91-94 20231502-3 2010 More recently, hydroxyurea-associated squamous dysplasia has been characterized as a premalignant precursor to hydroxyurea-associated nonmelanoma skin cancers and shown to manifest abnormal p53 expression. Hydroxyurea 15-26 P53 Homo sapiens 190-193 20231502-7 2010 CONCLUSIONS: We suggest that dermatomyositis-like eruption and hydroxyurea-associated squamous dysplasia represent similar clinical manifestations of a common underlying chronic phototoxic process involving aberrant keratinocyte p53 expression mediated by hydroxyurea"s antimetabolite properties and UV radiation exposure. Hydroxyurea 63-74 P53 Homo sapiens 229-232 19788889-7 2010 Although the HCT116 colon cancer cells did not mount a significant DNA damage response following Nutlin-3 treatment, Nutlin-3 enhanced the DNA damage response to the nucleotide synthesis inhibitor hydroxyurea in a p53-dependent manner. nutlin 3 117-125 P53 Homo sapiens 214-217 19788889-7 2010 Although the HCT116 colon cancer cells did not mount a significant DNA damage response following Nutlin-3 treatment, Nutlin-3 enhanced the DNA damage response to the nucleotide synthesis inhibitor hydroxyurea in a p53-dependent manner. Hydroxyurea 197-208 P53 Homo sapiens 214-217 19954744-5 2010 However, the role of SNP309 in hepatocarcinogenesis with respect to TP53 mutations is unknown. snp309 21-27 P53 Homo sapiens 68-72 19880522-13 2010 Staurosporine stress of ID8 cells promoted endogenous Pyk2 nuclear accumulation and enhanced Pyk2 binding to p53. Staurosporine 0-13 P53 Homo sapiens 109-112 19949306-3 2010 We showed that 2-methoxyestradiol (2-ME), an antitumoral compound, enhances autophagy and apoptosis in Ewing sarcoma cells through the activation of both p53 and JNK pathways. 2-Methoxyestradiol 15-33 P53 Homo sapiens 154-157 19949306-3 2010 We showed that 2-methoxyestradiol (2-ME), an antitumoral compound, enhances autophagy and apoptosis in Ewing sarcoma cells through the activation of both p53 and JNK pathways. 2-Methoxyestradiol 35-39 P53 Homo sapiens 154-157 19853978-0 2010 The role of p53 in the cellular toxicity by active trans-platinum complexes containing isopropylamine and hydroxymethylpyridine. 2-propylamine 87-101 P53 Homo sapiens 12-15 20185936-6 2010 PenA also protected against a CS-induced increase in carbonyls (oxidized proteins) and decrease in p53 levels (in the presence of saliva) and mitochondrial membrane potential (a hallmark of CS-induced apoptotic cell death). Cesium 30-32 P53 Homo sapiens 99-102 20185936-7 2010 Malfunctioning p53 often characterizes carcinogenesis of CS-induced cancers. Cesium 57-59 P53 Homo sapiens 15-18 20185936-8 2010 CONCLUSIONS: Redox-active iron and copper in pleural fluid and saliva, upon encounter with CS, may be responsible for this carcinogenesis, mediated via alteration of p53 function. Cesium 91-93 P53 Homo sapiens 166-169 20681406-13 2010 The data suggest that ING1 contributes to TSA-induced apoptosis in GBM cells with deficient p53 and p14(ARF)/p16(INK4a) functions, possibly by regulating FADD/caspase 3 signaling. trichostatin A 42-45 P53 Homo sapiens 92-95 19858204-6 2009 Additionally, cells treated with anti-cancer drug etoposide underwent apoptosis in association with the transcriptional enhancement of TAp63 in a p53-independent manner, and the knockdown of the endogenous TLP reduced etoposide-induced apoptosis through repression of TAp63 expression. Etoposide 50-59 P53 Homo sapiens 146-149 19766654-6 2009 In fact, substitution of this Asn to Ala of CHC diminished its ability to interact with p53, leading to reduced activity to transactivate p53. Asparagine 30-33 P53 Homo sapiens 138-141 19732843-7 2009 Moreover, genistein enhances the phosphorylation and activation of p53, while decreases the ratio of Bcl-2/Bax and Bcl-xL/Bax and the level of phosphorylated Akt, which result in cells undergoing apoptosis. Genistein 10-19 P53 Homo sapiens 67-70 19857493-3 2009 In contrast to the wt p53 cell lines, the mt p53-R175H cell line was resistant to staurosporine (STS)-mediated detachment and caspase-3 activation. Staurosporine 82-95 P53 Homo sapiens 45-48 19857493-3 2009 In contrast to the wt p53 cell lines, the mt p53-R175H cell line was resistant to staurosporine (STS)-mediated detachment and caspase-3 activation. Staurosporine 97-100 P53 Homo sapiens 45-48 19457607-7 2009 The PI3K/Akt inhibitor LY294002 significantly increased the amount of p53 protein and ATO-induced apoptosis in both cell lines and decreased G2/M phase arrest of MGC803 cells. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 23-31 P53 Homo sapiens 70-73 19996705-11 2009 Moreover, both CS and PS induced expression of the p53 tumor suppressor gene and the Cdk inhibitor p21. Cesium 15-17 P53 Homo sapiens 51-54 19459175-8 2009 Even though DATS treatment resulted in stabilization and Ser15 phosphorylation of p53, the knockdown of p53 protein failed to rescue DATS-induced mitotic arrest. diallyl trisulfide 12-16 P53 Homo sapiens 82-85 21160963-5 2009 Interestingly, p53 expression was upregulated at the invasive stage of BilIN, but was low in noninvasive BilIN, while p53 expression was upregulated in IPN-B1 and reached a plateau in IPN-B2 and invasive ICC. Bile Pigments 105-110 P53 Homo sapiens 15-18 19699254-4 2009 Capsaicin also induced degradation of tumor suppressor p53; this effect was enhanced by the ER stressor tunicamycin. Tunicamycin 104-115 P53 Homo sapiens 55-58 19658174-6 2009 The CS-dose-dependent induction and increase in the extent of phosphorylation of ATM, Chk2, H2AX, and p53 were seen in both cell types. Cesium 4-6 P53 Homo sapiens 102-105 18716605-4 2008 Genistein also decreased cisplatin-induced apoptosis by regulating p53 induction in kidney. Genistein 0-9 P53 Homo sapiens 67-70 19010883-2 2008 We report here that treatment of cells with sodium arsenite at the concentrations close to environmental exposure is associated with the up-regulation of Hdm2 and the accumulation of p53 in the cytoplasm. sodium arsenite 44-59 P53 Homo sapiens 183-186 18779328-5 2008 In addition, STX6 can be induced by DNA damage and Mdm2 inhibitor Nutlin-3 in a p53-dependent manner. nutlin 3 66-74 P53 Homo sapiens 80-83 21739974-0 2011 4-acetylantroquinonol B isolated from Antrodia cinnamomea arrests proliferation of human hepatocellular carcinoma HepG2 cell by affecting p53, p21 and p27 levels. 4-acetylantroquinonol B 0-23 P53 Homo sapiens 138-141 18850315-6 2008 Transfection of HUVEC with dominant negative p53 cDNA prevented the progesterone-induced increases in p21 and p27 promoter activity and protein level, decreases in thymidine incorporation, and capillary-like tube formation. Thymidine 164-173 P53 Homo sapiens 45-48 19794957-0 2009 Hypoxia-induced decrease in p53 protein level and increase in c-jun DNA binding activity results in cancer cell resistance to etoposide. Etoposide 126-135 P53 Homo sapiens 28-31 19794957-4 2009 Whereas the profile of c-Myc and NF-kappaB activity did not fit the effect of hypoxia on caspase 3 activity, hypoxia decreased basal p53 abundance and DNA binding activity as well as p53 etoposide-induced activation. Etoposide 187-196 P53 Homo sapiens 183-186 18822454-8 2008 Nevirapine treated cells strongly accumulated SA-b-Gal activity and also expressed increased levels of p53 and p21 when analyzed via RT-PCR. Nevirapine 0-10 P53 Homo sapiens 103-106 21739974-4 2011 The protein levels of p53 and p21 proteins were also increased when the cells were treated with low dosage (0.1 mug/mL) of 4-acetylantroquinonol B. 4-acetylantroquinonol 123-144 P53 Homo sapiens 22-25 19794957-5 2009 Short interfering RNA (siRNA) silencing evidenced that p53 was required for etoposide-induced apoptosis under normoxia. Etoposide 76-85 P53 Homo sapiens 55-58 19794957-12 2009 These data evidenced that hypoxia decreased the responsiveness of HepG2 cells to etoposide at least by two independent pathways involving p53 inhibition and c-jun activation. Etoposide 81-90 P53 Homo sapiens 138-141 21739974-10 2011 Our finding suggested that the 4-acetylantroquinonol B inhibits proliferation of HepG2 cells via affecting p53, p21 and p27 proteins, and can be considered as a potential cancer drug. 4-acetylantroquinonol B 31-54 P53 Homo sapiens 107-110 18697203-3 2008 However, gradual induction of p53 in tet-onSAOS2 cells resulted in a transient increase of the PDGFRB-promoter activity and its expression. tetramethylenedisulfotetramine 37-40 P53 Homo sapiens 30-33 18681908-8 2009 Activation of SIRT1 negatively regulates UV- and H(2)O(2)-induced p53 acetylation, because nicotinamide and sirtinol as well as SIRT1 siRNA enhance UV- and H(2)O(2)-induced p53 acetylation, whereas SIRT1 activator resveratrol inhibits it. sirtinol 108-116 P53 Homo sapiens 66-69 18697203-9 2008 Mitomycin treatment of MEF induced similar epigenetic modification of p53 and its binding to the promoter chromatin. Mitomycin 0-9 P53 Homo sapiens 70-73 21441950-8 2011 Instead, a natural antisense transcript of TP53, WRAP53, was strongly augmented by idarubicin and etoposide, but only less so by the other anthracyclines under study. Etoposide 98-107 P53 Homo sapiens 43-47 18697203-10 2008 Addition of a PDGFR tyrosine-kinase inhibitor to p53-inducing tet-onSAOS2 increased the number of apoptotic cells. tetramethylenedisulfotetramine 62-65 P53 Homo sapiens 49-52 18681908-8 2009 Activation of SIRT1 negatively regulates UV- and H(2)O(2)-induced p53 acetylation, because nicotinamide and sirtinol as well as SIRT1 siRNA enhance UV- and H(2)O(2)-induced p53 acetylation, whereas SIRT1 activator resveratrol inhibits it. sirtinol 108-116 P53 Homo sapiens 173-176 19421231-4 2009 We show here that nutlin-3, a potent antagonist of MDM2, activates the p53 pathway in all BL cell lines harboring wild-type p53, regardless of EBV status. nutlin 3 18-26 P53 Homo sapiens 71-74 19421231-4 2009 We show here that nutlin-3, a potent antagonist of MDM2, activates the p53 pathway in all BL cell lines harboring wild-type p53, regardless of EBV status. nutlin 3 18-26 P53 Homo sapiens 124-127 21519790-0 2011 Histone deacetylase inhibitors, valproic acid and trichostatin-A induce apoptosis and affect acetylation status of p53 in ERG-positive prostate cancer cells. trichostatin A 50-64 P53 Homo sapiens 115-118 19662644-0 2009 EGCG inhibits protein synthesis, lipogenesis, and cell cycle progression through activation of AMPK in p53 positive and negative human hepatoma cells. epigallocatechin gallate 0-4 P53 Homo sapiens 103-106 19662644-1 2009 In the previous studies, (-)-epigallocatechin-3-gallate (EGCG) has been shown to have anticarcinogenic effects via modulation in protein expression of p53. epigallocatechin gallate 25-55 P53 Homo sapiens 151-154 19662644-1 2009 In the previous studies, (-)-epigallocatechin-3-gallate (EGCG) has been shown to have anticarcinogenic effects via modulation in protein expression of p53. epigallocatechin gallate 57-61 P53 Homo sapiens 151-154 18647660-0 2008 Differential expression of TP53 associated genes in Fanconi anemia cells after mitomycin C and hydroxyurea treatment.

Hydroxyurea 95-106 P53 Homo sapiens 27-31 18647660-8 2008 The MMC induced damage was correlated with a general increase in expression of TP53-modulated DNA damage stress response genes involved in processes such as DNA repair, cell cycle progression, and apoptosis. Mitomycin 4-7 P53 Homo sapiens 79-83 19662644-2 2009 Using p53 positive Hep G2 and p53 negative Hep 3B cells, we found that treatment of EGCG resulted in dose-dependent inhibition of cellular proliferation, which suggests that the interaction of EGCG with p53 may not fully explain its inhibitory effect on proliferation. epigallocatechin gallate 84-88 P53 Homo sapiens 6-9 21519790-11 2011 We found that VPA and TSA induce apoptosis, upregulate p21/Waf1/CIP1, repress TMPRSS2-ERG expression and affect acetylation status of p53 in VCaP cells. trichostatin A 22-25 P53 Homo sapiens 134-137 19662644-2 2009 Using p53 positive Hep G2 and p53 negative Hep 3B cells, we found that treatment of EGCG resulted in dose-dependent inhibition of cellular proliferation, which suggests that the interaction of EGCG with p53 may not fully explain its inhibitory effect on proliferation. epigallocatechin gallate 84-88 P53 Homo sapiens 30-33 19662644-2 2009 Using p53 positive Hep G2 and p53 negative Hep 3B cells, we found that treatment of EGCG resulted in dose-dependent inhibition of cellular proliferation, which suggests that the interaction of EGCG with p53 may not fully explain its inhibitory effect on proliferation. epigallocatechin gallate 84-88 P53 Homo sapiens 30-33 18847459-11 2008 Furthermore, genistein induced the expression of apoptotic and anti-migratory proteins p53 and p38 in all cell lines.

Etoposide 68-77 P53 Homo sapiens 81-84 18838865-3 2008 Here, we show by epistatic analysis that p53 inhibition results in a maximum level of autophagy that cannot be further enhanced by a variety of different autophagy inducers including lithium, tunicamycin-induced stress of the endoplasmic reticulum (ER) or inhibition of Bcl-2 and Bcl-X(L) with the BH3 mimetic ABT737. Tunicamycin 192-203 P53 Homo sapiens 41-44 18838865-4 2008 Chemical inducers of autophagy (including rapamycin, lithium, tunicamycin and ABT737) induced rapid depletion of the p53 protein. Tunicamycin 62-73 P53 Homo sapiens 117-120 18838865-4 2008 Chemical inducers of autophagy (including rapamycin, lithium, tunicamycin and ABT737) induced rapid depletion of the p53 protein. ABT-737 78-84 P53 Homo sapiens 117-120 19662644-6 2009 Here, we showed that EGCG activated AMPK in both p53 positive and negative human hepatoma cells. epigallocatechin gallate 21-25 P53 Homo sapiens 49-52 19662644-10 2009 In p53 positive Hep G2 cells, EGCG blocked the progression of cell cycle at G1 phase by inducing p53 expression and further up-regulating p21 expression. epigallocatechin gallate 30-34 P53 Homo sapiens 3-6 19662644-10 2009 In p53 positive Hep G2 cells, EGCG blocked the progression of cell cycle at G1 phase by inducing p53 expression and further up-regulating p21 expression. epigallocatechin gallate 30-34 P53 Homo sapiens 97-100 19662644-11 2009 However, EGCG inducted apoptosis in p53 negative Hep 3B cells. epigallocatechin gallate 9-13 P53 Homo sapiens 36-39 19546226-3 2009 XCT790 induces, in a p53-independent manner, the expression of the cell cycle inhibitor p21(waf/cip)(1) at the protein, mRNA, and promoter level, leading to an accumulation of hypophosphorylated Rb. XCT790 0-6 P53 Homo sapiens 21-24 20734047-9 2011 Satraplatin treatment induces p53-related genes and its direct microRNA target of miR-34a independently. satraplatin 0-11 P53 Homo sapiens 30-33 19714248-5 2009 METHODOLOGY/PRINCIPAL FINDINGS: Upon exposure of colon and lung cancer cells to hypoxia, by either low oxygen or cobalt, HIPK2 function was impaired allowing for increased HIF-1alpha expression and inhibiting the p53-apoptotic response to drug. Cobalt 113-119 P53 Homo sapiens 213-216 19723076-7 2009 Omega-3 fatty acids inhibited oxidative stress-induced cell death, DNA fragmentation, and induction of p53 and Bax of the cells. Fatty Acids, Omega-3 0-19 P53 Homo sapiens 103-106 18571879-6 2008 We also analyzed the splice patterns of apoptosis-related genes in p53-deficient U2OS cells following treatment with the genotoxic drug mitomycin C. Mitomycin 136-147 P53 Homo sapiens 67-70 18618574-10 2008 The p53 overexpression was associated with MDM2 SNP309. snp309 48-54 P53 Homo sapiens 4-7 21120637-6 2011 Remarkably, the synergistic effect of 8-Br-cAMP and VPA on cellular reprogramming may be due to the transient decrease of p53 protein during the early stages of reprogramming. 8-Bromo Cyclic Adenosine Monophosphate 38-47 P53 Homo sapiens 122-125 18604159-6 2008 Several distinct autophagy inducers (e.g., starvation, rapamycin, lithium, tunicamycin and thapsigargin) stimulate the rapid degradation of p53. Tunicamycin 75-86 P53 Homo sapiens 140-143 19638586-4 2009 We show that, along with p53 reactivation, the proapoptotic p53-activator HIPK2 is degraded by MDM2 in Nutlin-3-treated cells, but activated by transiently reduced MDM2 levels in RITA-treated ones. nutlin 3 103-111 P53 Homo sapiens 25-28 19638586-4 2009 We show that, along with p53 reactivation, the proapoptotic p53-activator HIPK2 is degraded by MDM2 in Nutlin-3-treated cells, but activated by transiently reduced MDM2 levels in RITA-treated ones. nutlin 3 103-111 P53 Homo sapiens 60-63 21120637-10 2011 In addition, 8-Br-cAMP and VPA have a synergistic effect on cellular reprogramming, which may be in part due to the transient down-regulation of the p53 signaling pathway during the early stages of reprogramming. 8-Bromo Cyclic Adenosine Monophosphate 13-22 P53 Homo sapiens 149-152 21508668-7 2011 Biochemical studies showed that zinc partly induced the transition of mutant p53 protein (reactive to conformation-sensitive PAb240 antibody for mutant conformation) into a functional conformation (reactive to conformation-sensitive PAb1620 antibody for wild-type conformation). pab240 125-131 P53 Homo sapiens 77-80 19637078-6 2009 Other genes regulated by the transformation-related protein 53 (Trp53/p53) such as Bcl2-associated X protein (Bax) or etoposide-induced-2.4 (Ei24/PIG8) were not upregulated. Etoposide 118-127 P53 Homo sapiens 29-62 18677110-1 2008 The cellular response to Nutlin-3, a small-molecule inhibitor of the p53 repressor MDM2, varies widely among human cancer-derived cell types. nutlin 3 25-33 P53 Homo sapiens 69-72 19477925-3 2009 We find that in estrogen receptor (ER)-positive breast cancer cells, UV or ionizing radiation and hydroxyurea rapidly activate ATR-dependent phosphorylation of endogenous p53 and Chk1. Hydroxyurea 98-109 P53 Homo sapiens 171-174 21454715-7 2011 A citrulline-mimicking Arg-NLS-Gln ING4 mutant, which has all Arg residues in the NLS mutated to Gln, loses its affinity for p53, can no longer promote p53 acetylation, and results in repression of downstream p21 expression. Glutamine 31-34 P53 Homo sapiens 125-128 19536869-6 2009 The specific ATM inhibitor caffeine significantly decreased ISL-mediated G2/M arrest by inhibiting the phosphorylation of p53 (Serine15) and Chk2. serine15 127-135 P53 Homo sapiens 122-125 18644983-7 2008 In addition, our data suggest that trichostatin A-induced p21(WAF1/Cip1) protein expression might be mediated through a p53-independent and HDAC deacetylase-independent pathway. trichostatin A 35-49 P53 Homo sapiens 120-123 18645003-1 2008 Previous studies comparing the effects of two histone deacetylase (HDAC) inhibitors, trichostatin A (TSA) and CG-1521, have shown that these compounds selectively inhibit HDAC and induce differentially acetylated p53 isoforms and assembly of mutually exclusive transcriptional complexes on the p21 promoter. trichostatin A 85-99 P53 Homo sapiens 213-216 18645003-1 2008 Previous studies comparing the effects of two histone deacetylase (HDAC) inhibitors, trichostatin A (TSA) and CG-1521, have shown that these compounds selectively inhibit HDAC and induce differentially acetylated p53 isoforms and assembly of mutually exclusive transcriptional complexes on the p21 promoter. trichostatin A 101-104 P53 Homo sapiens 213-216 19558638-9 2009 CONCLUSION: These results suggest that hydroxyurea exerts differential effects on the promoter-binding functions of p53 and p73 and illustrate the power of model-based algorithm for promoter array in the analyses of promoter occupancy profiles of highly homologous transcription factors. Hydroxyurea 39-50 P53 Homo sapiens 116-119 21454715-7 2011 A citrulline-mimicking Arg-NLS-Gln ING4 mutant, which has all Arg residues in the NLS mutated to Gln, loses its affinity for p53, can no longer promote p53 acetylation, and results in repression of downstream p21 expression. Glutamine 31-34 P53 Homo sapiens 152-155 21292642-4 2011 We found that prolonged exposure of immortalized p53-knocked down human bronchial epithelial cells (p53(low)HBECs) to low levels of arsenite (NaAsO2, 2.5 muM) caused malignant transformation that was accompanied by epithelial to mesenchymal transition (EMT) and reduction in the levels of miR-200 family members. sodium arsenite 142-148 P53 Homo sapiens 49-52 19216720-8 2009 Meanwhile, the use of 3-aminobenzamide, a PARP-1 inhibitor known to prevent AIF (apoptosis-inducing factor) release, significantly decreases staurosporine-induced death in these p53mt carcinoma cells, suggesting a preferential implication of caspase-independent apoptosis. Staurosporine 141-154 P53 Homo sapiens 178-181 19216720-9 2009 On the other hand, we show that p53, whose activity is modulated by pifithrin-alpha, isolated as a suppressor of p53-mediated transactivation, or by PRIMA-1 (p53 reactivation and induction of massive apoptosis), that reactivates mutant p53, causes cytochrome c release as well as mitochondrio-nuclear AIF translocation in staurosporine-induced apoptosis of cervical carcinoma cells. Staurosporine 322-335 P53 Homo sapiens 32-35 19216720-10 2009 CONCLUSIONS: The present paper highlights that staurosporine engages the intrinsic mitochondrial apoptotic pathway via caspase-8 or caspase-9 signalling cascades and via caspase-independent cell death, as well as through p53 activity. Staurosporine 47-60 P53 Homo sapiens 221-224 19771878-7 2009 CONCLUSION: Oxymatrine could notably inhibit the HepG2 cells proliferation probably via upregulating the expression of the Bax and downregulating the expression of Bcl-2 and P53. oxymatrine 12-22 P53 Homo sapiens 174-177 18492823-7 2008 Moreover, oxidized LDL increased luciferase activity of p53 in endothelial cells transfected with a p53 promoter construct, the increase of which was strikingly downregulated by EGCG and hesperetin. epigallocatechin gallate 178-182 P53 Homo sapiens 56-59 18492823-7 2008 Moreover, oxidized LDL increased luciferase activity of p53 in endothelial cells transfected with a p53 promoter construct, the increase of which was strikingly downregulated by EGCG and hesperetin. epigallocatechin gallate 178-182 P53 Homo sapiens 100-103 21972525-0 2011 [The roles of Ku80/p53 pathway in silica-induced cell cycle changes in human embryo lung fibroblasts].

Alpha-Amanitin 28-42 P53 Homo sapiens 92-95 18289623-7 2008 The RNA synthesis inhibitor alpha-amanitin induced similar to mafosfamide more apoptosis in p53(wt) than in p53(mt) cells. Alpha-Amanitin 28-42 P53 Homo sapiens 108-111 21972525-7 2011 CONCLUSION: Ku80/p53 pathway plays a role in the cell cycle charges induced by silica in human embryo lung fibroblasts.

Dinucleoside Phosphates 36-48 P53 Homo sapiens 150-153 21510868-2 2011 We have recently shown that p53 is critical for the inhibitory effect of cAMP on genotoxic agents-mediated apoptosis in BCP-ALLs. bcp-alls 120-128 P53 Homo sapiens 28-31 19188164-12 2009 CONCLUSION: These findings suggest that the MDM2 antagonist Nutlin-3 may be an effective agent in the treatment of MCL with or without wt-TP53. nutlin 3 60-68 P53 Homo sapiens 138-142 21274505-6 2011 Furthermore, activation of p53 and AMPK was detected in etoposide-treated cells and inhibition of AMPK triggered apoptosis through suppression of autophagy. Etoposide 56-65 P53 Homo sapiens 27-30 19091346-18 2009 CONCLUSIONS: Finasteride administered 30 days before surgery appears to decrease the apoptotic factors caspase-7 and IGFBP-3 in cancer cells, while having little to no effect on caspase-3, insulin growth factor-1, bcl-2, p53 and p21. Finasteride 13-24 P53 Homo sapiens 221-224 21212274-2 2011 However, little is known about the regulation of the two other p53-family members, p63 and p73, by nitrogen oxides. Nitrogen Oxides 99-114 P53 Homo sapiens 63-66 20077225-0 2009 The role of p53 in silica-induced cellular and molecular responses associated with carcinogenesis. Silicon Dioxide 19-25 P53 Homo sapiens 12-15 21394211-3 2011 Here, we have analyzed the p53-regulated pathways induced by Actinomycin D and Etoposide treatment resulting in more growth arrested versus apoptotic cells respectively. Etoposide 79-88 P53 Homo sapiens 27-30 20077225-3 2009 The goal of this study was to compare freshly fractured and aged silica-induced molecular alterations in human immortalized/transformed bronchial epithelial cells (BEAS-IIB) and lung cancer cells with altered (H460) or deficient (H1299) p53 expression. Silicon Dioxide 65-71 P53 Homo sapiens 237-240 20077225-7 2009 p53 protein was present in the BEAS-IIB and was absent in cancer cell lines after silica exposure. Silicon Dioxide 82-88 P53 Homo sapiens 0-3 20077225-8 2009 Exposure to freshly fractured silica also resulted in a rise in aneuploidy in cancer cells with a significantly greater increase in p53-deficient cells. Silicon Dioxide 30-36 P53 Homo sapiens 132-135 21145583-7 2011 The expression of p53 increased in HeLa cell cultures treated with camptothecin (positive control) for 24h, and the formation of p53Ser15 and p53Ser46 was detected in cell nuclei by Western blotting. Camptothecin 67-79 P53 Homo sapiens 18-21 20077225-10 2009 These results suggest that altered and deficient p53 affects the cellular response to freshly fractured silica exposure, and thereby enhances susceptibility and augments cell proliferation and lung cancer development. Silicon Dioxide 104-110 P53 Homo sapiens 49-52 21145583-7 2011 The expression of p53 increased in HeLa cell cultures treated with camptothecin (positive control) for 24h, and the formation of p53Ser15 and p53Ser46 was detected in cell nuclei by Western blotting. Camptothecin 67-79 P53 Homo sapiens 129-132 21145583-9 2011 Both camptothecin and TEGDMA increased p53 expression to some extent in the nuclear fraction in human transformed pulp-derived cells (tHPC), and similar effects were detected in RAW264.7 macrophages. Camptothecin 5-17 P53 Homo sapiens 39-42 19373614-2 2009 Here we report two chemopreventive agents, selenite and genistein, that have synergistic effects on apoptosis, cell cycle arrest, and associated signaling pathways in p53-expressing LNCaP and p53-null PC3 prostate cancer cells. Genistein 56-65 P53 Homo sapiens 167-170 21217086-2 2011 METHODS: We investigated associations between serum polyunsaturated fatty acid concentrations and p53 expression in normal skin, as a biomarker of early UV-induced carcinogenesis, in an unselected sample of Australian adults.

Genistein 56-65 P53 Homo sapiens 192-195 19047160-9 2008 In contrast, dasatinib, a dual Bcr-Abl and Src kinase inhibitor, inhibited the phosphorylation of both BCR-ABL and Lyn, and induced apoptosis of the Bcr-Abl cell line overexpressing p53/56 Lyn. Dasatinib 13-22 P53 Homo sapiens 182-185 21217086-5 2011 RESULTS: There was an inverse association, showing a dose-response relationship, between total n-3 fatty acid serum concentrations and p53 immunoreactivity in the whole epidermis and the basal layer.

Pifithrin-Beta 0-22 P53 Homo sapiens 40-43 19383329-3 2008 Here we show that STIMA-1, a low molecular weight compound with some structural similarities to the previously identified molecule CP-31398, can stimulate mutant p53 DNA binding in vitro and induce expression of p53 target proteins and trigger apoptosis in mutant p53-expressing human tumor cells.

Aflatoxin B1 118-130 P53 Homo sapiens 72-75 17849423-5 2008 The HCC patients with XRCC1 genotypes with 399 Gln (namely: XRCC1-AG/GG) exhibited a significantly higher frequency of the p53 hotspot mutations in codon 249 than those with the wild-type homozygote of XRCC1 [namely: XRCC1-AA, adjusted odds ratio (OR) = 6.77, 95% confidence interval (CI) = 4.34-10.57]. Glutamine 47-50 P53 Homo sapiens 123-126 18413792-10 2008 In human cancer xenograft models, FK228 significantly increased the therapeutic effectiveness of p53 as well as p63 gene therapy. romidepsin 34-39 P53 Homo sapiens 97-100 18358501-7 2008 Interestingly, 9 out of 14 (64.3%) tumors carrying p53 mutations displayed substitution of serine by arginine at codon 249, a characteristic change believed to be induced by aflatoxin-B1.

Silicon Dioxide 41-47 P53 Homo sapiens 95-98 18373075-5 2008 However, at a low dose of etoposide (repairable damage), Bid activated the S phase checkpoint through the up-regulation of p21 and p27, which are both p53-independent. Etoposide 26-35 P53 Homo sapiens 151-154 18366759-6 2008 Of note is the inhibition of the etoposide-induced activation of p53 under hypoxia. Etoposide 33-42 P53 Homo sapiens 65-68 20727582-7 2010 Silica nanoparticles also activated c-Jun N-terminal kinase (JNK), c-Jun, p53, caspase-3 and NF-kappaB, increased Bax expression and suppressed Bcl-2 protein. Silicon Dioxide 0-6 P53 Homo sapiens 74-77 20727582-9 2010 In summary, our findings demonstrated that silica nanoparticles could induce dysfunction of endothelial cells through oxidative stress via JNK, p53 and NF-kappaB pathways, suggesting that exposure to silica nanoparticles may be a significant risk for the development of cardiovascular diseases such as atherosclerosis and thrombus. Silicon Dioxide 43-49 P53 Homo sapiens 144-147 18366759-8 2008 Cluster analysis of data unravels several possible pathways involved in the hypoxia-induced protection against etoposide-induced apoptosis: one of them could be the inhibition of p53 activity under hypoxia since caspase 3 activity parallels Bax and Bak expression profile. Etoposide 111-120 P53 Homo sapiens 179-182 20713149-11 2010 Furthermore, pretreatment with curculigoside decreased the activity of caspase-3 and p53 mRNA expression, which was known to play a key role in H(2)O(2)-induced cell apoptosis. curculigoside 31-44 P53 Homo sapiens 85-88 18279445-6 2008 Leptin and fAd dose-dependently potentiated p53 expression in PC3 cells (P < 0.001); leptin and gAd also increased p53 expression (P < 0.05 and P < 0.001). Flavin-Adenine Dinucleotide 11-14 P53 Homo sapiens 44-47 20811720-5 2010 In this study, we investigated the effect of trichostatin A or TSA (an HDAC inhibitor), and epoxomycin (a proteasome inhibitor) on MYCN and p53 expression in MYCN-amplified neuroblastoma cells. trichostatin A 45-59 P53 Homo sapiens 140-143 18409045-0 2008 A new triterpenoid from Panax ginseng exhibits cytotoxicity through p53 and the caspase signaling pathway in the HepG2 cell line. triterpenoid TP-222 6-18 P53 Homo sapiens 68-71 21163061-8 2010 The bufalin-induced apoptosis was confirmed by increased expression of tumor suppressor protein p53, bax and decreased expression of bcl-2. bufalin 4-11 P53 Homo sapiens 96-99 18206427-8 2008 Etoposide-induced phosphorylation of p53 relied mainly on RIP, whereas activation of Chk1, Chk2 depended largely on TIP. Etoposide 0-9 P53 Homo sapiens 37-40 18206427-9 2008 Both RIP and TIP played roles in activating non-homologous end joining pathway, while only RIP modulated etoposide-induced cell killing in a p53-dependent manner. Etoposide 105-114 P53 Homo sapiens 141-144 18418047-8 2008 However, HAUSP downregulation causes resistance to Camptothecin- and irradiation-induced apoptosis, which correlates with suppressed mitochondrial translocation of p53. Camptothecin 51-63 P53 Homo sapiens 164-167 18026140-8 2008 p53 levels comparable to those found in induced mammalian cells confer synthetic sickness or lethality in combination with deletions in genes encoding transcription elongation factors; p53 likewise confers hypersensitivity to the anti-elongation drug 6-azauracil. azauracil 251-262 P53 Homo sapiens 0-3 20622893-7 2010 BRCA1-IRIS abrogation of the homeostatic balance maintained by the p38MAPK-p53-WIP1 pathway suppressed cell death induced by a lethal dose of short-wavelength UV light, and high dosage of etoposide or H(2)O(2), and allowed cells to survive and proliferate post geno-/cell-toxic stresses. Etoposide 188-197 P53 Homo sapiens 75-78 18026140-8 2008 p53 levels comparable to those found in induced mammalian cells confer synthetic sickness or lethality in combination with deletions in genes encoding transcription elongation factors; p53 likewise confers hypersensitivity to the anti-elongation drug 6-azauracil. azauracil 251-262 P53 Homo sapiens 185-188 18296683-7 2008 We have applied this method to a mixed set of mutation spectra observed in exons 5, 7 and 8 of TP53 from cancers of brain, breast, skin, colon, oesophagus, liver, head and neck, stomach and lung (smokers and non-smokers) and spectra induced by benzo[a]pyrene diol epoxide, ultraviolet (UV) B, UVC, simulated sunlight and hydroxyl radicals in the cII, supF and yeast p53 model systems. Hydroxyl Radical 321-338 P53 Homo sapiens 95-99 18292936-8 2008 Western blot analysis of apoptosis-related proteins demonstrated that treatment with MZ-5-156 (10(-6) M) for 48 h significantly increased the protein levels of Fas, phospho-p53 (Ser46), p53AIP1 (p53-regulated Apoptosis-Inducing Protein 1), and caspase-8, -9, and -3, and decreased the protein level of Bcl-2. mz-5 85-89 P53 Homo sapiens 173-176 20664969-0 2010 Oridonin induces G2/M cell cycle arrest and apoptosis through MAPK and p53 signaling pathways in HepG2 cells. oridonin 0-8 P53 Homo sapiens 71-74 18208837-4 2008 Time-dependent decrease was observed in APE1 mRNA and protein levels in the human colorectal cancer line HCT116 p53(+/+), but not in the isogenic p53 null mutant after treatment with camptothecin, a DNA topoisomerase I inhibitor. Camptothecin 183-195 P53 Homo sapiens 112-115 17932621-11 2008 Under basal growth conditions and in response to the chemotherapeutic agent, etoposide, WIP1 antagonized p53-mediated apoptosis in medulloblastoma cell lines. Etoposide 77-86 P53 Homo sapiens 105-108 18324703-2 2008 Using analysis of proteins related to cell cycle and apoptotic pathways, we confirmed an elevated level of p53 accompanying p21 Waf1/Cip1 protein in genistein-treated or genistin-treated A549 and WI-38 cells, but not in HeLa cells. Genistein 149-158 P53 Homo sapiens 107-110 18324703-3 2008 In addition, a p53-upregulated modulator of apoptosis (Puma) protein accumulated significantly in genistein-treated A549 and WI-38 cells, but not in genistin-treated or beta-estradiol-treated cells, though the growth of any ingredient-treated cells was severely inhibited. Genistein 98-107 P53 Homo sapiens 15-18 18324703-4 2008 Intriguingly, the caspase-3 activity of genistein-treated A549 cells, in which Puma or p53 expression was knocked-down by RNA interference (RNAi), remained unaltered compared to that in cells transfected with irrelevant RNAi. Genistein 40-49 P53 Homo sapiens 87-90 20664969-7 2010 Immunoblot analysis demonstrated that oridonin treatment increased expression levels of p-JNK, p-p38, p-p53 and p21, elevated the level of cyclin B1/p-Cdc2 (Tyr15) complex, and inhibited the expression of p-ERK. oridonin 38-46 P53 Homo sapiens 104-107 18357397-9 2008 There was an increase in the p53 and p21 levels in response to genistein. Genistein 63-72 P53 Homo sapiens 29-32 18357397-13 2008 Moreover, the ectopic expression of temperature-sensitive p53V135A, which acts as a dominant-negative p53 mutant at 38.5 degrees C but assumes p53 wild-type properties at 32.5 degrees C, in LN-18 or LNT-229 cells, had no effect on genistein cytotoxicity at either temperature. Genistein 231-240 P53 Homo sapiens 58-61 20664969-9 2010 In conclusion, oridonin induced G2/M cell cycle arrest and apoptosis in HepG2 cells through MAPK and p53 pathways, which advances our understanding on the molecular mechanisms of oridonin in hepatocarcinoma management. oridonin 15-23 P53 Homo sapiens 101-104 18202783-3 2008 The data obtained show that normal human lymphocytes exposed in vitro to known DNA-damaging agents, e.g. H2O2, ionizing radiation and mitomycin C, exhibit an asynchronous replication of the genes TP53 and RB1.

Etoposide 71-80 P53 Homo sapiens 215-218 20662736-7 2010 Anthracycline (topoisomerase II inhibitors such as mitoxantrone and ellipticine) and camptothecin (topoisomerase I inhibitor) derivatives including topotecan induce DNA double strand breaks, which activate the p53 pathway through the ataxia telangiectasia mutated-checkpoint kinase 2 (ATM-CHK2) DNA damage response pathway. Camptothecin 85-97 P53 Homo sapiens 210-213 18330473-4 2008 LY294002 activated autophagy by activating p53 and caspase-3, and induced apoptosis by up-regulating p53 and p53-up-regulated modulator of apoptosis (PUMA). 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 0-8 P53 Homo sapiens 43-46 18330473-4 2008 LY294002 activated autophagy by activating p53 and caspase-3, and induced apoptosis by up-regulating p53 and p53-up-regulated modulator of apoptosis (PUMA). 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 0-8 P53 Homo sapiens 101-104 18330473-4 2008 LY294002 activated autophagy by activating p53 and caspase-3, and induced apoptosis by up-regulating p53 and p53-up-regulated modulator of apoptosis (PUMA). 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 0-8 P53 Homo sapiens 101-104 18330473-5 2008 Therefore, LY294002 might induce cytotoxicity in SGC7901 cells through activation of p53 and the downstream point PUMA. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 11-19 P53 Homo sapiens 85-88 19002263-8 2008 Mucinous feature, signet ring cells, and p53-negativity were associated with CIMP-high in only univariate analysis. cimp-high 77-86 P53 Homo sapiens 41-44 17897804-2 2007 The imidazoline compound (Nutlin-3) is a promising small molecule antagonist of the MDM2-p53 interaction. nutlin 3 26-34 P53 Homo sapiens 89-92 18060027-3 2007 report on their study of a nonimmunodeficient mouse model of UVB-induced skin cancer and human skin carcinoma cells and show that the mutant p53 conformation-modifying drug CP-31398 not only treats these tumors but also prevents them (see the related article beginning on page 3753).

We also find that oxymatrine down-regulate expression of bcl-2 gene while up-regulate expression of p53 gene. oxymatrine 0-10 P53 Homo sapiens 238-241 16458489-6 2006 Oxymatrine induce apoptosis of SMMC-7721 cells and apoptotic rate amount to about 60% after treatment with 1.0 mg/ml oxymatrine for 48 h. We also find that oxymatrine down-regulate expression of bcl-2 gene while up-regulate expression of p53 gene. oxymatrine 117-127 P53 Homo sapiens 238-241 16458489-6 2006 Oxymatrine induce apoptosis of SMMC-7721 cells and apoptotic rate amount to about 60% after treatment with 1.0 mg/ml oxymatrine for 48 h. We also find that oxymatrine down-regulate expression of bcl-2 gene while up-regulate expression of p53 gene. oxymatrine 156-166 P53 Homo sapiens 238-241 20429622-2 2010 A combination of camptothecin and etoposide (1 microg/ml + 10 microg/ml) proved to be efficient in both types of cell lines, although mutant p53 cells exhibited a higher resistance. Camptothecin 17-29 P53 Homo sapiens 141-144 16458489-7 2006 These results demonstrate that oxymatrine inhibit the proliferation and induce apoptosis of human hepatoma SMMC-7721 cells, and suggest that this effect was mediated probably by a significant cell cycle blockage in G2/M and S phase, down-regulation of bcl-2 and up-regulation of p53. oxymatrine 31-41 P53 Homo sapiens 279-282 16325212-0 2006 The p33ING1b tumor suppressor cooperates with p53 to induce apoptosis in response to etoposide in human osteosarcoma cells. Etoposide 85-94 P53 Homo sapiens 46-49 16325212-4 2006 p33ING1b increased etoposide-induced growth inhibition and apoptosis to a much greater degree in p53+/+ U2OS cells than in p53-mutant MG63 cells. Etoposide 19-28 P53 Homo sapiens 97-100 16410370-7 2006 Aflatoxin B1, hepatitis B virus, hepatitis C virus, and vinyl chloride all caused TP53 mutations in human liver tumors, but the mutation spectrum for each agent differed. Aflatoxin B1 0-12 P53 Homo sapiens 82-86 20661829-0 2010 Protection of p53 wild type cells from taxol by genistein in the combined treatment of lung cancer. Genistein 48-57 P53 Homo sapiens 14-17 16344270-9 2006 Violacein causes cell cycle block at G(1), upregulates p53, p27 and p21 levels and decreases the expression of cyclin D1. violacein 0-9 P53 Homo sapiens 55-58 19996219-10 2009 SNP309 was significantly associated with increased sensitivity to alkylating agents and topoisomerase I inhibitors in the cells with wild-type TP53. snp309 0-6 P53 Homo sapiens 143-147 16302260-3 2006 We recently identified a synthetic thiazolidin compound, 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidione (DBPT), that induces apoptosis in human colon cancer cells, independent of p53 and P-glycoprotein status. 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidione 57-119 P53 Homo sapiens 195-198 16325212-6 2006 Together, our data indicate that p33ING1b prominently enhances etoposide-induced apoptosis through p53-dependent pathways in human osteosarcoma cells. Etoposide 63-72 P53 Homo sapiens 99-102 16378598-3 2006 Although a PI3 kinase inhibitor, LY294002, by itself does not induce apoptotic cell death, LY294002 selectively and markedly enhances the apoptosis-inducing efficacy of doxorubicin: such an enhanced cell death is only detected in tumor cells in which the PI3 kinase/Akt pathway is constitutively activated, and it is totally dependent on the functional p53 pathway. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 91-99 P53 Homo sapiens 353-356 16478747-2 2006 SNP309 induces an increase in the level of Mdm2 protein, which causes attenuation of the p53 pathway. snp309 0-6 P53 Homo sapiens 89-92 16319068-4 2006 We had found that treatment of cells with camptothecin, a topoisomerase 1 inhibitor, led to the export of prohibitin and p53 from the nucleus to the mitochondria. Camptothecin 42-54 P53 Homo sapiens 121-124 19751709-8 2009 This effect correlated with lowered basal levels of p53, as well as with an attenuated p53 response induced by etoposide and leptomycin B. Etoposide 111-120 P53 Homo sapiens 87-90 16271357-0 2006 Erybraedin C and bitucarpin A, two structurally related pterocarpans purified from Bituminaria bituminosa, induced apoptosis in human colon adenocarcinoma cell lines MMR- and p53-proficient and -deficient in a dose-, time-, and structure-dependent fashion. erybraedin C 0-12 P53 Homo sapiens 175-178 16271357-8 2006 Erybraedin C similarly affects the survival of HT29 (MMR +/+, p53 -/- and Bcl-2 +/+) and LoVo (MMR -/-, p53 +/+ and Bcl-2 -/-) cells (LD(50): 1.94 and 1.73 microg/ml, respectively). erybraedin C 0-12 P53 Homo sapiens 62-65 16271357-8 2006 Erybraedin C similarly affects the survival of HT29 (MMR +/+, p53 -/- and Bcl-2 +/+) and LoVo (MMR -/-, p53 +/+ and Bcl-2 -/-) cells (LD(50): 1.94 and 1.73 microg/ml, respectively). erybraedin C 0-12 P53 Homo sapiens 104-107 16513842-11 2006 The synergistic effect of simultaneous treatment with trichostatin A and doxorubicin is mediated via inhibition of AR expression, induction of protease activity, increased expression of p53, and proteolysis of p21. trichostatin A 54-68 P53 Homo sapiens 186-189 16434701-1 2006 The main regulator of the human tumor suppresser gene p21(waf1/cip1) is the transcription factor p53, but more recently it has been suggested to be a primary anti-proliferative target for the nuclear receptor VDR in the presence of its ligand 1alpha,25-dihydroxyvitamin D3 (1alpha,25(OH)2D3). 25-dihydroxyvitamin d3 250-272 P53 Homo sapiens 97-100 19345001-3 2009 Aflatoxin B1, the most commonly occurring and potent of the aflatoxins is associated with a specific AGG to AGT transversion mutation at codon 249 of the p53 gene in human HCC, providing mechanistic support to a causal link between exposure and disease. Aflatoxin B1 0-12 P53 Homo sapiens 154-157 16341031-0 2006 The p53 family inhibitor DeltaNp73 interferes with multiple developmental programs. deltanp73 25-34 P53 Homo sapiens 4-7 16580789-3 2006 Moreover, oxidative stress by reactive oxygen species (ROS) such as the hydroxyl radical (*OH) produced by ionizing radiation (carcinogenic) triggers p53 activation in response to the damage of DNA (followed by initiation of DNA-repair mechanisms). Hydroxyl Radical 72-88 P53 Homo sapiens 150-153 16432175-0 2006 Benzodiazepinedione inhibitors of the Hdm2:p53 complex suppress human tumor cell proliferation in vitro and sensitize tumors to doxorubicin in vivo. benzodiazepinedione 0-19 P53 Homo sapiens 43-46 16219768-4 2005 Here, we determined that UV light, anisomycin, etoposide, and hypoxic stress rapidly induced phosphorylation of p53 at Ser46 and WOX1 at Tyr33 (phospho-WOX1) and their binding interactions in several tested cancer cells. Etoposide 47-56 P53 Homo sapiens 112-115 16413759-2 2006 In order to identify new p53 downstream genes, we established a new system of p53 gene inducible expression, U251-pTet-p53 cell line, with the Tet-On Gene Expression System, in which exogenous p53 gene could overexpress in doxycycline (Dox) medium but not in the medium without Dox. tetramethylenedisulfotetramine 115-118 P53 Homo sapiens 78-81 16467109-6 2006 Interestingly, radiosensitization by TSA in cell lines expressing p53 was more pronounced than in isogenic lines lacking p53. trichostatin A 37-40 P53 Homo sapiens 66-69 16467109-7 2006 Radiosensitization of cells expressing p53 by TSA was reduced by pifithrin-alpha, a small-molecule inhibitor of p53. trichostatin A 46-49 P53 Homo sapiens 39-42 16467109-7 2006 Radiosensitization of cells expressing p53 by TSA was reduced by pifithrin-alpha, a small-molecule inhibitor of p53. trichostatin A 46-49 P53 Homo sapiens 112-115 19715480-0 2009 p53 gene expression and 2-methoxyestradiol treatment differentially induce nuclear factor kappa B activation in human lung cancer cells with different p53 phenotypes. 2-Methoxyestradiol 24-42 P53 Homo sapiens 151-154 16467399-5 2006 In JAR cells, etoposide increased expression of the proteins including IFNgammaR, p53 and pro-caspase 3 as well as IRF-1 mRNA and IFNgamma-pretreatment apparently promoted up-regulation of these molecules expression. Etoposide 14-23 P53 Homo sapiens 82-85 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 95-113 P53 Homo sapiens 30-33 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 95-113 P53 Homo sapiens 64-67 15933740-0 2005 The PI3K inhibitor LY294002 prevents p53 induction by DNA damage and attenuates chemotherapy-induced apoptosis. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 19-27 P53 Homo sapiens 37-40 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 95-113 P53 Homo sapiens 64-67 15933740-5 2005 We report here that exposure to LY294002, a potent PI3K inhibitor, aborts the activation of p53 by several drugs commonly used in cancer chemotherapy. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 32-40 P53 Homo sapiens 92-95 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 115-119 P53 Homo sapiens 30-33 15933740-6 2005 Concomitantly, LY294002 attenuates p53-dependent, chemotherapy-induced apoptosis of cancer cells. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 15-23 P53 Homo sapiens 35-38 16280384-0 2006 Aflatoxin B1 alters the expression of p53 in cytochrome P450-expressing human lung cells. Aflatoxin B1 0-12 P53 Homo sapiens 38-41 16280384-2 2006 Mutations (and altered expression) of the tumor suppresser gene p53 have been observed in liver tumors from patients exposed to high dietary AFB1. Aflatoxin B1 141-145 P53 Homo sapiens 64-67 16280384-4 2006 We examined the effects of low concentrations of AFB1 on the expression of p53 and MDM2 in human bronchial epithelial cells (BEAS-2B) transfected with cDNA for either cytochrome P450 (CYP) 1A2 (B-CMV1A2) or CYP 3A4 (B3A4), two isozymes that are responsible for AFB1 activation in human liver and possibly the lung. Aflatoxin B1 49-53 P53 Homo sapiens 75-78 19715480-4 2009 We show that expression of wt-p53 from a recombinant adenovirus-p53 followed by treatment with 2-methoxyestradiol (2-ME), an endogenous, nontoxic, estrogenic metabolite, resulted in differential NF-kappaB activation and inhibitor kappaB alpha (IkappaB-alpha) degradation in three different human lung cancer cell lines with different p53 phenotypes. 2-Methoxyestradiol 115-119 P53 Homo sapiens 64-67 16430208-7 2006 Flow cytometry results and transfection assays indicated that tetravalent decaarginyl peptides (10R-p53(tet) and NLS-10R-p53(tet)) were the peptides most efficiently routed into cells. tetramethylenedisulfotetramine 62-65 P53 Homo sapiens 100-103 20025574-0 2009 Association of p53 with Bid induces cell death in response to etoposide treatment in hepatocellular carcinoma. Etoposide 62-71 P53 Homo sapiens 15-18 16430208-7 2006 Flow cytometry results and transfection assays indicated that tetravalent decaarginyl peptides (10R-p53(tet) and NLS-10R-p53(tet)) were the peptides most efficiently routed into cells. tetramethylenedisulfotetramine 62-65 P53 Homo sapiens 121-124 16298862-8 2005 PBN pre-treated cells showed significant inhibition of apoptotic features such as activation of caspase-3, up-regulation of Bax and p53, and down-regulation of Bcl-2 compared to control cells upon exposure to ionizing radiation. phenyl-N-tert-butylnitrone 0-3 P53 Homo sapiens 132-135 20025574-6 2009 Here, we showed that etoposide-induced DNA damage could significantly induce p53 and Bid nuclear export. Etoposide 21-30 P53 Homo sapiens 77-80 20025574-7 2009 When cells were stimulated by etoposide, p53 could, through the association with Bid, cause translocation of Bid from the nucleus to the cytoplasm and on to its ultimate location in the mitochondria. Etoposide 30-39 P53 Homo sapiens 41-44 17080554-7 2006 These results suggest that EGCG may have an inhibitory effect on UVB-induced photo-damage and apoptosis by blocking the cytokine secretion and the mRNA expressions of p53, p21 and c-fos genes. epigallocatechin gallate 27-31 P53 Homo sapiens 167-170 16170329-6 2005 Methyl jasmonate induced mostly apoptotic death in the wt p53-expressing cells, while no signs of early apoptosis were detected in mutant p53-expressing cells. methyl jasmonate 0-16 P53 Homo sapiens 58-61 20025574-8 2009 p53 was physically associated with Bid, and both p53 and Bid cooperatively promoted cell death induced by etoposide. Etoposide 106-115 P53 Homo sapiens 0-3 20025574-8 2009 p53 was physically associated with Bid, and both p53 and Bid cooperatively promoted cell death induced by etoposide. Etoposide 106-115 P53 Homo sapiens 49-52 20025574-10 2009 These findings reveal a novel mechanism by which p53 is associated with Bid in the nucleus to facilitate exportation of Bid to the mitochondria and induce apoptosis in response to etoposide-induced DNA damage in HCC. Etoposide 180-189 P53 Homo sapiens 49-52 16374552-2 2006 We have now investigated whether these parameters influence susceptibility to okadaic acid induced cell death in EGF-receptor overexpressing mutant p53 A431 human carcinoma. Okadaic Acid 78-90 P53 Homo sapiens 148-151 16374552-3 2006 Exposure of these cells to 20 nM okadaic acid induced apoptosis-associated caspase 3 activation, DNA fragmentation, cleavage of Poly ADP-Ribose Polymerase (PARP), p53-independent expression of pro-apoptotic bax, and loss of proliferation-promoting cyclin D1. Okadaic Acid 33-45 P53 Homo sapiens 163-166 16007163-4 2005 Blocking AKT with the PI3K/AKT inhibitor LY294002 or AKT SiRNA prevented NF-kappaB activation and inhibition of p53. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 41-49 P53 Homo sapiens 112-115 19641144-3 2009 Here we demonstrate for the first time increased DNA damage via 8-oxoguanine in the skin and plasma in association with epidermal up-regulated phosphorylated/acetylated p53 and high levels of the p53 antagonist p76(MDM2). 8-hydroxyguanine 64-76 P53 Homo sapiens 169-172 16007163-5 2005 Treatment of C81 cells with LY294002 resulted in an increase in the p53-responsive gene MDM2, suggesting a role for AKT in the Tax-mediated regulation of p53 transcriptional activity. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 28-36 P53 Homo sapiens 68-71 16007163-5 2005 Treatment of C81 cells with LY294002 resulted in an increase in the p53-responsive gene MDM2, suggesting a role for AKT in the Tax-mediated regulation of p53 transcriptional activity. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 28-36 P53 Homo sapiens 154-157 16007163-6 2005 Further, we show that LY294002 treatment of C81 cells abrogates in vitro IKKbeta phosphorylation of p65 and causes a reduction of p65 Ser-536 phosphorylation in vivo, steps critical to p53 inhibition. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 22-30 P53 Homo sapiens 185-188 17113242-1 2006 INTRODUCTION: The most frequent mutation in human hepatocellular carcinoma (HCC) in populations exposed to a high dietary intake of aflatoxin B1 (AFB1) is a mutation in codon 249 of the p53 gene. Aflatoxin B1 132-144 P53 Homo sapiens 186-189 17113242-1 2006 INTRODUCTION: The most frequent mutation in human hepatocellular carcinoma (HCC) in populations exposed to a high dietary intake of aflatoxin B1 (AFB1) is a mutation in codon 249 of the p53 gene. Aflatoxin B1 146-150 P53 Homo sapiens 186-189 17113242-3 2006 We hypothesized that the combination of schistosomiasis and aflatoxin B1 increases the incidence of p53 gene mutation. Aflatoxin B1 60-72 P53 Homo sapiens 100-103 19641144-3 2009 Here we demonstrate for the first time increased DNA damage via 8-oxoguanine in the skin and plasma in association with epidermal up-regulated phosphorylated/acetylated p53 and high levels of the p53 antagonist p76(MDM2). 8-hydroxyguanine 64-76 P53 Homo sapiens 196-199 17113242-8 2006 CONCLUSION: These data suggest that schistosomiasis and exposure to aflatoxin B1 act synergistically to increase the incidence of p53 gene mutation. Aflatoxin B1 68-80 P53 Homo sapiens 130-133 16227412-8 2005 The recruitment of the p53-dependent apoptosis pathway was suggested by the up-regulation of p53, p21, Bax, DR-4, DR-5, and p53 phosphorylated on Ser15; down-regulation of Bcl-2; and activation of caspase-8, -9, -7, and -3 in cells treated with 100 nmol/L WMC-79. wmc 256-259 P53 Homo sapiens 23-26 21160963-4 2009 In both the BilIN and IPNB series, the expression of p21, p53, and cyclin D1 was upregulated with histological progression. Bile Pigments 12-17 P53 Homo sapiens 58-61 21160963-5 2009 Interestingly, p53 expression was upregulated at the invasive stage of BilIN, but was low in noninvasive BilIN, while p53 expression was upregulated in IPN-B1 and reached a plateau in IPN-B2 and invasive ICC. Bile Pigments 71-76 P53 Homo sapiens 15-18 20157557-0 2009 Reduced transcriptional activity in the p53 pathway of senescent cells revealed by the MDM2 antagonist nutlin-3. nutlin 3 103-111 P53 Homo sapiens 40-43 16200332-6 2005 The expression of p53 was demonstrated using the avidin-biotin complex immunoperoxidase method and the monoclonal antibody DO7. avidin-biotin 49-62 P53 Homo sapiens 18-21 16141004-3 2005 SNP309 was shown to result, via Sp1, in higher levels of MDM2 RNA and protein, and subsequent attenuation of the p53 pathway. snp309 0-6 P53 Homo sapiens 113-116 16403018-7 2006 DNA adducts of trans-PtHMP also reduce the affinity of the p53 protein to its consensus DNA sequence. trans-PtCl(2)NH(3)(4-hydroxymethylpyridine) 15-26 P53 Homo sapiens 59-62 16354677-5 2006 Acetyl-p53 was also increased by the histone deacetylase (HDAC) class I/II inhibitor trichostatin A (TSA). trichostatin A 85-99 P53 Homo sapiens 7-10 16354677-5 2006 Acetyl-p53 was also increased by the histone deacetylase (HDAC) class I/II inhibitor trichostatin A (TSA). trichostatin A 101-104 P53 Homo sapiens 7-10 16354677-6 2006 EX-527 and TSA acted synergistically to increase acetyl-p53 levels, confirming that p53 acetylation is regulated by both SIRT1 and HDACs. trichostatin A 11-14 P53 Homo sapiens 56-59 16260623-3 2005 Compared to vector-transfected cells, H1299 cells expressing mutant p53 showed a survival advantage when treated with etoposide, a common chemotherapeutic agent; however, cells expressing the transactivation-deficient triple mutant p53-D281G (L22Q/W23S) had significantly lower resistance to etoposide. Etoposide 118-127 P53 Homo sapiens 68-71 16177561-1 2005 CP-31398 activates wild-type p53 by a novel mechanism that does not involve phosphorylation of the amino-terminus of p53 and disassociation of MDM2. CP 31398 0-8 P53 Homo sapiens 29-32 16177561-2 2005 To identify more potent CP-31398-like p53 activators, we synthesized 4 acridine derivatives with a similar structure to CP-31398. CP 31398 24-32 P53 Homo sapiens 38-41 16177561-2 2005 To identify more potent CP-31398-like p53 activators, we synthesized 4 acridine derivatives with a similar structure to CP-31398. CP 31398 120-128 P53 Homo sapiens 38-41 16260623-3 2005 Compared to vector-transfected cells, H1299 cells expressing mutant p53 showed a survival advantage when treated with etoposide, a common chemotherapeutic agent; however, cells expressing the transactivation-deficient triple mutant p53-D281G (L22Q/W23S) had significantly lower resistance to etoposide. Etoposide 292-301 P53 Homo sapiens 68-71 16260623-6 2005 Treatment of H1299 cells expressing p53-R175H with small interfering RNA specific for NF-kappaB2 made these cells more sensitive to etoposide. Etoposide 132-141 P53 Homo sapiens 36-39 16048565-1 2005 BACKGROUND AND AIMS: A specific mutation at codon 249 of the p53 tumor suppressor gene (guanine to thymine; arginine to serine [249(serine)p53]) is present in the cell-free plasma of 30-47% of patients with hepatocellular carcinoma (HCC) in regions with uniformly high levels of dietary exposure to the fungal toxin, aflatoxin B(1). Aflatoxin B1 317-328 P53 Homo sapiens 61-64 19584398-9 2009 However, in p53-null K562 cells, phorbol esters induce miR-34a expression independently of p53 by activating an alternative phorbol ester-responsive promoter to produce a longer pri-miR-34a transcript. Phorbol Esters 33-47 P53 Homo sapiens 12-15 16048565-1 2005 BACKGROUND AND AIMS: A specific mutation at codon 249 of the p53 tumor suppressor gene (guanine to thymine; arginine to serine [249(serine)p53]) is present in the cell-free plasma of 30-47% of patients with hepatocellular carcinoma (HCC) in regions with uniformly high levels of dietary exposure to the fungal toxin, aflatoxin B(1). Aflatoxin B1 317-328 P53 Homo sapiens 139-142 16048565-9 2005 CONCLUSIONS: The 249(serine)p53 mutation is found less often in the serum of patients with HCC in a region with variable levels of exposure to aflatoxin B(1) than in those with uniformly high levels of exposure, but the mutation does occur in black Africans with presumed lower levels of exposure to the fungal toxin. Aflatoxin B1 143-154 P53 Homo sapiens 28-31 15833387-0 2005 Liriodenine inhibits the proliferation of human hepatoma cell lines by blocking cell cycle progression and nitric oxide-mediated activation of p53 expression. liriodenine 0-11 P53 Homo sapiens 143-146 19584398-9 2009 However, in p53-null K562 cells, phorbol esters induce miR-34a expression independently of p53 by activating an alternative phorbol ester-responsive promoter to produce a longer pri-miR-34a transcript. Phorbol Esters 33-46 P53 Homo sapiens 12-15 15833387-2 2005 This study was designed to assess cell cycle arrest, the production of nitric oxide (NO) and p53 expression in liriodenine-treated human hepatoma cell lines, including wild-type p53 (Hep G2 and SK-Hep-1). liriodenine 111-122 P53 Homo sapiens 93-96 15970518-6 2005 Interestingly, we have found that DTX reduces the expression of mutated p53 in HT-29 and increases the expression of wild type in KB and HCC1937 cells. Digitoxigenin 34-37 P53 Homo sapiens 72-75 15970518-7 2005 Moreover, DTX reduces ubiquitination of the wild type p53 in KB and HCC1937 cells and increases the ubiquitin-conjugated form of mutated p53 in HT-29 cells.

Etoposide 123-132 P53 Homo sapiens 14-17 15970518-7 2005 Moreover, DTX reduces ubiquitination of the wild type p53 in KB and HCC1937 cells and increases the ubiquitin-conjugated form of mutated p53 in HT-29 cells. Digitoxigenin 10-13 P53 Homo sapiens 137-140 19541822-0 2009 Forodesine has high antitumor activity in chronic lymphocytic leukemia and activates p53-independent mitochondrial apoptosis by induction of p73 and BIM. forodesine 0-10 P53 Homo sapiens 85-88 16093994-0 2005 Differential regulation of p21waf-1/cip-1 and Mdm2 by etoposide: etoposide inhibits the p53-Mdm2 autoregulatory feedback loop. Etoposide 54-63 P53 Homo sapiens 88-91 15958570-4 2005 Sublethal concentrations of camptothecin reduced the IC50 of agonistic anti-Fas antibody (CH-11) 10-fold, from 500 to 50 ng/mL, in human U87 glioblastoma cells (p53 wild-type). Camptothecin 28-40 P53 Homo sapiens 161-164 15958570-4 2005 Sublethal concentrations of camptothecin reduced the IC50 of agonistic anti-Fas antibody (CH-11) 10-fold, from 500 to 50 ng/mL, in human U87 glioblastoma cells (p53 wild-type). 4-dimethylamino-3',4'-dimethoxychalcone 90-95 P53 Homo sapiens 161-164 19541822-7 2009 Forodesine induces transcriptional up-regulation of p73, a p53-related protein able to overcome the resistance to apoptosis of CLL cells lacking functional p53. forodesine 0-10 P53 Homo sapiens 59-62 19541822-9 2009 In conclusion, forodesine induces apoptosis of CLL cells bypassing the DNA-damage/ATM/p53 pathway and might represent a novel chemotherapeutic approach that deserves clinical investigation. forodesine 15-25 P53 Homo sapiens 86-89 19488905-2 2009 Etoposide initiated DNA-damage signaling via ATM kinase and activated p53 pathway and caspase-2. Etoposide 0-9 P53 Homo sapiens 70-73 15896459-0 2005 Etoposide (VP-16) elicits apoptosis following prolonged G2-M cell arrest in p53-mutated human non-small cell lung cancer cells. Etoposide 0-9 P53 Homo sapiens 76-79 15896459-1 2005 In this work, we described the proliferation of human non-small-cell-lung-cancer (NSCLC) cells H1437 harboring p53 alleles (proline-267) can be inhibited by low-dosage topoisomerase II inhibitor etoposide (VP-16) in vitro and in vivo. Etoposide 195-204 P53 Homo sapiens 111-114 16120219-7 2005 Both etoposide and CLP induced an accumulation of p53 protein and upregulation of p53 transcriptional target genes. Etoposide 5-14 P53 Homo sapiens 50-53 16120219-7 2005 Both etoposide and CLP induced an accumulation of p53 protein and upregulation of p53 transcriptional target genes. Etoposide 5-14 P53 Homo sapiens 82-85 19406223-0 2009 Identification of epigallocatechin-3-gallate in green tea polyphenols as a potent inducer of p53-dependent apoptosis in the human lung cancer cell line A549. epigallocatechin gallate 18-44 P53 Homo sapiens 93-96 16157026-6 2005 RT-PCR method was employed to detect the influence of EGCG on the expressions of hTERT, c-myc, p53 and mad1 genes in sensitive cancer cell line. epigallocatechin gallate 54-58 P53 Homo sapiens 95-98 16157026-11 2005 After EGCG administration, the expression of hTERT and c-myc genes in MKN45 cells was decreased, that of the mad1 gene increased, and that of the p53 gene unchanged. epigallocatechin gallate 6-10 P53 Homo sapiens 146-149 15941720-4 2005 Here, we report for the first time that during recovery from hydroxyurea treatment, the S100A2 protein translocated from the cytoplasm to the nucleus and co-localized with the tumor suppressor p53 in two different oral carcinoma cells (FADU and SCC-25). Hydroxyurea 61-72 P53 Homo sapiens 193-196 15856030-6 2005 Using isogenic colon cancer cell lines that differ only by the presence of the mutant Ras allele, HCT116 and Hke-3 cells, we demonstrated that signaling by oncogenic Ras promotes both accumulation of p53 and its phosphorylation on serine15 in response to 5-FU, a situation that favors apoptosis over growth arrest. serine15 231-239 P53 Homo sapiens 200-203 15892716-4 2005 We have studied the cellular effects of trichostatin A (TSA), a HDAC inhibitor, in a panel of melanoma cell lines and its mechanism of action in relation to p53. trichostatin A 40-54 P53 Homo sapiens 157-160 15892716-5 2005 TSA stabilized wild-type p53, but p53 protein accumulation was overridden by simultaneous downregulation of p53 mRNA leading to a decrease in p53 protein. trichostatin A 0-3 P53 Homo sapiens 25-28 19406223-6 2009 EGCg was a more potent inducer of p53-dependent transcription, and this induction was further supported by the induced level of p53 protein. epigallocatechin gallate 0-4 P53 Homo sapiens 34-37 19406223-6 2009 EGCg was a more potent inducer of p53-dependent transcription, and this induction was further supported by the induced level of p53 protein. epigallocatechin gallate 0-4 P53 Homo sapiens 128-131 15688418-2 2005 Sodium butyrate (NaB), a histone deacetylase inhibitor, has been shown to cause a G(1) cell cycle arrest by inducing p21(WAF1/CIP1) in a p53-independent manner. nab 17-20 P53 Homo sapiens 137-140 19406223-7 2009 RNA interference (RNAi)-mediated p53 knockdown completely abolished EGCg-induced apoptosis. epigallocatechin gallate 68-72 P53 Homo sapiens 33-36 15688418-3 2005 In this report, we present evidence for activation of p53 pathway by NaB and its role in the NaB-mediated growth suppression. nab 69-72 P53 Homo sapiens 54-57 15905168-4 2005 Cellular levels of the p21(waf1/cip1) protein and p21(waf1/cip1) mRNA were increased through a p53-independent pathway, possibly because of the stabilization of p21(waf1/cip1) mRNA in chloramphenicol-treated cells. Chloramphenicol 184-199 P53 Homo sapiens 95-98 15688418-3 2005 In this report, we present evidence for activation of p53 pathway by NaB and its role in the NaB-mediated growth suppression. nab 93-96 P53 Homo sapiens 54-57 19406223-9 2009 Taken together, these results indicate that EGCg, among several green tea polyphenols, is a potent apoptosis inducer that functions exclusively through a p53-dependent pathway in A549 cells. epigallocatechin gallate 44-48 P53 Homo sapiens 154-157 15688418-4 2005 Addition of NaB increased the levels of p53 involving a p14(ARF)-dependent post-transcriptional mechanism. nab 12-15 P53 Homo sapiens 40-43 19398128-4 2009 RESULTS: p53 AAbs are associated with high grade, but not low grade ovarian carcinoma. p-Aminoazobenzene 13-17 P53 Homo sapiens 9-12 15688418-5 2005 NaB induced p53 is functional as it activated p53-specific reporter, induced the level of p21(WAF1/CIP1), inhibited cellular DNA synthesis and induced apoptosis. nab 0-3 P53 Homo sapiens 12-15 15688418-5 2005 NaB induced p53 is functional as it activated p53-specific reporter, induced the level of p21(WAF1/CIP1), inhibited cellular DNA synthesis and induced apoptosis. nab 0-3 P53 Homo sapiens 46-49 15688418-6 2005 By using HPV 16 E6 stable transfectants as well as p53 null cancer cells, we show that NaB suppresses the growth of WT p53 containing cells more efficiently. nab 87-90 P53 Homo sapiens 51-54 15688418-6 2005 By using HPV 16 E6 stable transfectants as well as p53 null cancer cells, we show that NaB suppresses the growth of WT p53 containing cells more efficiently. nab 87-90 P53 Homo sapiens 119-122 15688418-7 2005 NaB inhibited DNA synthesis to similar extent both in the presence and absence of p53. nab 0-3 P53 Homo sapiens 82-85 15688418-8 2005 However, NaB treatment lead to a major G(2)/M arrest of cells in the presence of p53, while cells without wild-type p53 accumulated mainly in G(1) phase of the cell cycle. nab 9-12 P53 Homo sapiens 81-84 16024610-8 2005 NO treatment also induced the phosphorylation of p53 at Ser15; pretreatment with phosphoinositide-3 kinase (PI3K) family inhibitors, wortmannin, LY294002, and caffeine, blocked such phosphorylation, but the p38 mitogen-activated protein kinase inhibitor, SB203580, did not. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 145-153 P53 Homo sapiens 49-52 15896711-7 2005 These appear to be followed by the specific activation of AMPK and the up-regulation of p53, p21, and Bax by genistein. Genistein 109-118 P53 Homo sapiens 88-91 19242657-0 2009 Tunicamycin suppresses cisplatin-induced HepG2 cell apoptosis via enhancing p53 protein nuclear export. Tunicamycin 0-11 P53 Homo sapiens 76-79 15833387-4 2005 The p53, iNOS expression and intracellular NO level were markedly increased in Hep G2 cells after liriodenine treatment. liriodenine 98-109 P53 Homo sapiens 4-7 15833387-5 2005 A NO inhibitor, carboxy-PTIO inhibited the p53 expression induced by liriodenine. liriodenine 69-80 P53 Homo sapiens 43-46 15688418-10 2005 These results suggest that p53 pathway mediates in part growth suppression by NaB and the p53 status may be an important determinant of chemosensitivity in HDI based cancer chemotherapy. nab 78-81 P53 Homo sapiens 27-30 19242657-4 2009 In order to further explore the mechanism underlying tumor resistance to cisplatin, we observed that increased nuclear export of endogenous p53 protein by pharmacological inducers of ER stress, such as tunicamycin, was associated with the suppression of cisplatin-induced apoptosis. Tunicamycin 202-213 P53 Homo sapiens 140-143 15833387-7 2005 These results demonstrate that NO production and p53 expression are critical factors in liriodenine-induced growth inhibition in human wild-type p53 hepatoma cells. liriodenine 88-99 P53 Homo sapiens 49-52 15833387-7 2005 These results demonstrate that NO production and p53 expression are critical factors in liriodenine-induced growth inhibition in human wild-type p53 hepatoma cells. liriodenine 88-99 P53 Homo sapiens 145-148 19513516-0 2009 Trichostatin A with adenovirus-mediated p53 gene transfer synergistically induces apoptosis in breast cancer cell line MDA-MB-231. trichostatin A 0-14 P53 Homo sapiens 40-43 15942663-3 2005 Here, we examined the molecular mechanisms whereby the PI3K inhibitor LY294002 sensitized p53- and Fas-deficient hepatoma cells to etoposide and camptothecin. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 70-78 P53 Homo sapiens 90-93 19216720-0 2009 Spatiotemporal activation of caspase-dependent and -independent pathways in staurosporine-induced apoptosis of p53wt and p53mt human cervical carcinoma cells. Staurosporine 76-89 P53 Homo sapiens 111-114 19216720-0 2009 Spatiotemporal activation of caspase-dependent and -independent pathways in staurosporine-induced apoptosis of p53wt and p53mt human cervical carcinoma cells. Staurosporine 76-89 P53 Homo sapiens 121-124 19216720-2 2009 Our laboratory has reported that p53 is a key contributor of mitochondrial apoptosis in cervical carcinoma cells after staurosporine exposure. Staurosporine 119-132 P53 Homo sapiens 33-36 19519319-1 2009 By analyzing the cDNA obtained from 16 B-cell chronic lymphocytic leukemia (B-CLL) patient samples, we found that Nutlin-3, a small molecule inhibitor of MDM2/p53 interaction, induced a characteristic gene expression profile (GEP) signature in 13 out of 16 B-CLL samples. nutlin 3 114-122 P53 Homo sapiens 159-162 15930285-7 2005 The DNA methyltransferase inhibitor zebularine reverses the methylation of the p53 promoter, allowing the resumption of its expression. pyrimidin-2-one beta-ribofuranoside 36-46 P53 Homo sapiens 79-82 15930285-8 2005 However, when zebularine is withdrawn from the cells, the reestablishment of the original CpG island methylation within the p53 promoter does not occur in the absence of IL-6, and cells which do not receive IL-6 eventually die, as p53 expression continues unchecked by remethylation. pyrimidin-2-one beta-ribofuranoside 14-24 P53 Homo sapiens 124-127 15930285-8 2005 However, when zebularine is withdrawn from the cells, the reestablishment of the original CpG island methylation within the p53 promoter does not occur in the absence of IL-6, and cells which do not receive IL-6 eventually die, as p53 expression continues unchecked by remethylation. pyrimidin-2-one beta-ribofuranoside 14-24 P53 Homo sapiens 231-234 15930285-10 2005 Consistent with this model, when cells that express IL-6 in an autocrine fashion are subjected to identical treatment, p53 expression is reduced shortly after withdrawal of zebularine. pyrimidin-2-one beta-ribofuranoside 173-183 P53 Homo sapiens 119-122 15870916-10 2005 Retinol significantly decreased (p<0.05) invasive capabilities of cells across matrigel coated invasion chambers and significantly reduced (p<0.05) PCNA, Fra-1, mutant p53 and increased Rb protein expression levels in comparison to non-retinol-treated ones when assayed using immunofluorescent staining coupled with confocal microscopy. Vitamin A 0-7 P53 Homo sapiens 174-177 15892716-7 2005 Inhibiting p53 function by a dominant negative p53 (p53(175His)) confirmed that the HDAC inhibitor induced apoptosis was independent of wild-type p53, even though TSA slightly activated p53 in a reporter assay. trichostatin A 163-166 P53 Homo sapiens 11-14 19445707-0 2009 Increased susceptibility of spinal muscular atrophy fibroblasts to camptothecin is p53-independent. Camptothecin 67-79 P53 Homo sapiens 83-86 15753076-9 2005 Senescence induction, tested as staining for SA-beta-gal, in reoxygenated progenitor cells was closely correlated with extent of DNA damage and phosphorylation of ATM at Ser-1981 and p53 at Ser-15. 2-(2-quinolinyl)-1H-indene--1,3(2H)-dione-6'-sulfonic acid 45-56 P53 Homo sapiens 183-186 15909125-0 2005 Etoposide (VP-16) sensitizes p53-deficient human non-small cell lung cancer cells to caspase-7-mediated apoptosis. Etoposide 0-9 P53 Homo sapiens 29-32 19445707-8 2009 Upon camptothecin treatment, levels of p53 were markedly increased. Camptothecin 5-17 P53 Homo sapiens 39-42 19445707-9 2009 To determine if p53 plays a role in the increased sensitivity of SMA fibroblasts to camptothecin, we analyzed the sensitivity of SMA fibroblasts to another DNA topoisomerase I inhibitor, beta-lapachone. Camptothecin 84-96 P53 Homo sapiens 16-19 19070402-2 2009 The thiosemicarbazones were cytotoxic against malignant RT2 glioblastoma cells (expressing p53 protein) with IC(50) values in the 7.3-360 microM range, and against malignant T98 glioblastoma cells (expressing mutant p53 protein) with IC(50) values in the 3.6-143 microM range. Thiosemicarbazones 4-22 P53 Homo sapiens 91-94 15746940-4 2005 TSA stabilizes the acetylation of p53 at Lys382, elevating p21 levels and inducing cell cycle arrest, but does not induce Bax translocation or apoptosis. trichostatin A 0-3 P53 Homo sapiens 34-37 19070402-2 2009 The thiosemicarbazones were cytotoxic against malignant RT2 glioblastoma cells (expressing p53 protein) with IC(50) values in the 7.3-360 microM range, and against malignant T98 glioblastoma cells (expressing mutant p53 protein) with IC(50) values in the 3.6-143 microM range. Thiosemicarbazones 4-22 P53 Homo sapiens 216-219 15846088-5 2005 The cell line that showed greatest reduction (85-90%) of p53 expression showed decreased p21 promoter activation after DNA damage with camptothecin, etoposide and MMS. Camptothecin 135-147 P53 Homo sapiens 57-60 15846088-5 2005 The cell line that showed greatest reduction (85-90%) of p53 expression showed decreased p21 promoter activation after DNA damage with camptothecin, etoposide and MMS. Etoposide 149-158 P53 Homo sapiens 57-60 19123473-4 2009 Cantharidin and norcantharidin, a derivative with reduced toxicity, decreased HLF protein levels and induced apoptosis in the AML cell line MV4-11 by modulating the expression of several molecules that govern survival pathway, including HLF, SLUG, NFIL3 and c-myc, thereby inducing p53 and the mitochondrial caspase cascade. norcantharidin 16-30 P53 Homo sapiens 282-285 19190243-8 2009 Therefore, therapeutic combinations of Nutlin-3 + gamma-secretase inhibitors might potentiate the cytotoxicity of Nutlin-3 in p53(wild-type) leukemic cells. nutlin 3 39-47 P53 Homo sapiens 126-129 15764647-1 2005 Treatment with epigallocatechin-3-gallate (EGCG), a polyphenolic compound of green tea, results in activation of p53 and induction of apoptosis in prostate cancer LnCaP cells. epigallocatechin gallate 15-41 P53 Homo sapiens 113-116 15764647-1 2005 Treatment with epigallocatechin-3-gallate (EGCG), a polyphenolic compound of green tea, results in activation of p53 and induction of apoptosis in prostate cancer LnCaP cells. epigallocatechin gallate 43-47 P53 Homo sapiens 113-116 15764647-2 2005 However, no direct evidence has delineated the role of p53 and p53-dependent pathways in EGCG-mediated apoptosis. epigallocatechin gallate 89-93 P53 Homo sapiens 63-66 15764647-4 2005 Treatment of the resultant cells, PC3-p53, with EGCG led to, as reported earlier in LnCaP cells, an increase in p53 protein, which exacerbated both G1 arrest and apoptosis. epigallocatechin gallate 48-52 P53 Homo sapiens 38-41 15764647-4 2005 Treatment of the resultant cells, PC3-p53, with EGCG led to, as reported earlier in LnCaP cells, an increase in p53 protein, which exacerbated both G1 arrest and apoptosis. epigallocatechin gallate 48-52 P53 Homo sapiens 112-115 19049493-8 2009 Reduction of Sp1 binding after activation of p53 with camptothecin was also observed in chromatin immunoprecipitation assays. Camptothecin 54-66 P53 Homo sapiens 45-48 15764647-6 2005 The cells lacking p53 continued to cycle and did not undergo apoptosis upon treatment with similar concentrations of EGCG, thus establishing the action of EGCG in a p53-dependent manner. epigallocatechin gallate 155-159 P53 Homo sapiens 18-21 15764647-6 2005 The cells lacking p53 continued to cycle and did not undergo apoptosis upon treatment with similar concentrations of EGCG, thus establishing the action of EGCG in a p53-dependent manner. epigallocatechin gallate 155-159 P53 Homo sapiens 165-168 15764647-8 2005 Inactivation of p53 using small interfering RNA (siRNA) rendered these cells resistant to EGCG-mediated apoptosis. epigallocatechin gallate 90-94 P53 Homo sapiens 16-19 15764647-13 2005 In summary, using isogenic cell lines and siRNA, we have clearly demonstrated that EGCG activates growth arrest and apoptosis primarily via p53-dependent pathway that involves the function of both p21 and Bax such that down-regulation of either molecule confers a growth advantage to the cells. epigallocatechin gallate 83-87 P53 Homo sapiens 140-143 15833870-0 2005 Phenoxodiol, a novel isoflavone, induces G1 arrest by specific loss in cyclin-dependent kinase 2 activity by p53-independent induction of p21WAF1/CIP1. phenoxodiol 0-11 P53 Homo sapiens 109-112 19261878-4 2009 Despite promoting nuclear p53 accumulation, Class I/II HDAC inhibitors (HDACIs) protected neurons from p53-dependent cell death induced by camptothecin, etoposide, heterologous p53 expression or the MDM2 inhibitor, nutlin-3a. Camptothecin 139-151 P53 Homo sapiens 103-106 15809436-2 2005 NQO1 binds and stabilizes WT p53, whereas NQO1 inhibitors including dicoumarol and various other coumarins and flavones induce ubiquitin-independent proteasomal p53 degradation and thus inhibit p53-induced apoptosis. Coumarins 97-106 P53 Homo sapiens 161-164 15809436-2 2005 NQO1 binds and stabilizes WT p53, whereas NQO1 inhibitors including dicoumarol and various other coumarins and flavones induce ubiquitin-independent proteasomal p53 degradation and thus inhibit p53-induced apoptosis. Coumarins 97-106 P53 Homo sapiens 161-164 15746577-5 2005 Our study reports here for the first time that the induction of p53 and the activity of the Fas/FasL apoptotic system may participate in the antiproliferative activity of casuarinin in A549 cells. casuarinin 171-181 P53 Homo sapiens 64-67 19261878-4 2009 Despite promoting nuclear p53 accumulation, Class I/II HDAC inhibitors (HDACIs) protected neurons from p53-dependent cell death induced by camptothecin, etoposide, heterologous p53 expression or the MDM2 inhibitor, nutlin-3a.

Cerulenin 22-31 P53 Homo sapiens 47-51 15583825-7 2005 To determine whether the up-regulation of TP53 following exposure to cerulenin or C75 was solely due to inhibition of endogenous fatty acid metabolism, we first evaluated the cytotoxic response to chemical FAS blockers on MCF-7 cells in which FAS gene expression was previously silenced by using the highly sequence-specific mechanism of RNA interference.

CP 31398 56-64 P53 Homo sapiens 80-83 14614447-6 2003 These observations point out some of the liabilities of CP-31398 as a prototype p53-based therapeutic and define a rationale for further refinement of small molecules that specifically target the p53 pathway, but lack the p53-independent effects.

Etoposide 37-46 P53 Homo sapiens 85-88 14583449-5 2003 Interestingly, ionizing radiation or etoposide, both of which stabilize and activate p53, diminished p53 binding in chromatin immunoprecipitation assays, concomitant with a 5-fold increase in Dnmt1 levels. Etoposide 37-46 P53 Homo sapiens 101-104 14728868-11 2003 Mifepristone up-regulated significantly the expression of p53 protein, but down-regulated the expression of bcl-2 protein (P < 0.01). Mifepristone 0-12 P53 Homo sapiens 58-61 14728868-12 2003 The expressive rates of p53 and bcl-2 proteins were (54.8 +/- 4.0)% and (10.1 +/- 1.2)%, respectively, when 3AO cells was cultured with mifepristone of 10 micro mol/L for 24 h. Compared with the expression rates of control group (27.1 +/- 3.3)% and (17.6 +/- 1.0)%, the difference was significant (P < 0.01). Mifepristone 136-148 P53 Homo sapiens 24-27 12876282-9 2003 Trichostatin A, a histone deacetylase inhibitor, relieved the p53 transrepression activity on MAD1. trichostatin A 0-14 P53 Homo sapiens 62-65 12954772-8 2003 Treatment with trichostatin A, which is an inhibitor of histone deacetylase, or PML over-expression relieved Daxx-mediated transcriptional repression of p53. trichostatin A 15-29 P53 Homo sapiens 153-156 12883741-0 2003 The alpha1-adrenoceptor antagonist terazosin induces prostate cancer cell death through a p53 and Rb independent pathway.

Oligodeoxyribonucleotides 53-73 P53 Homo sapiens 30-33 12794767-6 2003 Pretreatment of COLO 205 with p53-specific antisense oligodeoxynucleotide decreased the TB-induced elevations of p53 and p21/Cip1 proteins, which in turn led to arrest in the cell cycle at the G0/G1 phase. Oligodeoxyribonucleotides 53-73 P53 Homo sapiens 113-116 12767058-0 2003 Nonsteroidal anti-inflammatory drug-activated gene (NAG-1) is induced by genistein through the expression of p53 in colorectal cancer cells. Genistein 73-82 P53 Homo sapiens 109-112 12767058-5 2003 The induction of p53 (3 hr) precedes the induction of NAG-1 (12 hr), suggesting that genistein-induced NAG-1 expression is mediated by p53. Genistein 85-94 P53 Homo sapiens 17-20 12767058-5 2003 The induction of p53 (3 hr) precedes the induction of NAG-1 (12 hr), suggesting that genistein-induced NAG-1 expression is mediated by p53. Genistein 85-94 P53 Homo sapiens 135-138 12767058-8 2003 The expression of p53 was critical for NAG-1 promoter activity since no promoter activity was observed with genistein treatment in HCT-15 cells. Genistein 108-117 P53 Homo sapiens 18-21 12767058-9 2003 However, genistein-induced promoter activity was restored in HCT-15 cells by transfection with wild-type p53. Genistein 9-18 P53 Homo sapiens 105-108 12874009-2 2003 Here, we investigate the role of p53 in the G(2) arrest that occurs in response to the topoisomerase inhibitors etoposide and merbarone. Etoposide 112-121 P53 Homo sapiens 33-36 12874009-3 2003 In HT1080 cells expressing a dominant-negative form of p53, treatment with etoposide still caused G(2) arrest, but the arrest could be overcome by additional treatment with caffeine, which inhibits the damage-responsive kinases ataxia telangiectasia mutated (ATM) and atm and rad3-related (ATR). Etoposide 75-84 P53 Homo sapiens 55-58 12874009-5 2003 We conclude that etoposide activates two pathways, one of which depends on p53 and the other of which is sensitive to caffeine, and that either pathway is sufficient to activate G(2) arrest. Etoposide 17-26 P53 Homo sapiens 75-78 12807744-6 2003 Furthermore, caffeine also inhibited the accumulation of p53 by a variety of stress-inducing agents in vivo, such as 5-fluorouracil, doxorubicin, mitomycin C, camptothecin and roscovitine. Mitomycin 146-157 P53 Homo sapiens 57-60 12807744-6 2003 Furthermore, caffeine also inhibited the accumulation of p53 by a variety of stress-inducing agents in vivo, such as 5-fluorouracil, doxorubicin, mitomycin C, camptothecin and roscovitine. Camptothecin 159-171 P53 Homo sapiens 57-60 12792782-6 2003 During UA treatment, we also demonstrated that p53 was phosphorylated at serine 392 and translocated to the nucleus. ursolic acid 7-9 P53 Homo sapiens 47-50 12767922-6 2003 These data suggest that both genistein and etoposide induce p21(WAF1/Cip1) expression in a p53-dependent manner. Genistein 29-38 P53 Homo sapiens 91-94 12767922-6 2003 These data suggest that both genistein and etoposide induce p21(WAF1/Cip1) expression in a p53-dependent manner.

Cesium 37-39 P53 Homo sapiens 0-3 12690294-8 2003 Furthermore, examination of the levels of apoptosis regulatory proteins showed that, while levels of p53, Bax and p21 are higher, that of anti-apoptotic Bcl-2 is undetectable in cells treated with 2-ME compared with untreated controls. 2-Methoxyestradiol 197-201 P53 Homo sapiens 101-104 11923280-2 2002 Recent studies have reported that the phosphatidylinositol 3-OH-kinase-Akt pathway inhibits p53-mediated transcription and apoptosis, although the underlying mechanisms have yet to be determined. Phosphatidylinositols 38-58 P53 Homo sapiens 92-95 11923280-8 2002 The serum-induced increase in p53 ubiquitination was blocked by LY294002, a phosphatidylinositol 3-OH-kinase inhibitor. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 64-72 P53 Homo sapiens 30-33 11923280-8 2002 The serum-induced increase in p53 ubiquitination was blocked by LY294002, a phosphatidylinositol 3-OH-kinase inhibitor. Phosphatidylinositols 76-96 P53 Homo sapiens 30-33 12082016-11 2002 A reported clinical association of Tp53 immunopositive colorectal cancers with use of the antihypertensive agents was extended by the demonstration of hydralazine and nifedipine as Tp53-inducers. Hydralazine 151-162 P53 Homo sapiens 35-39 12606585-3 2003 We show that p53 and BLM accumulated after hydroxyurea (HU) treatment, and physically associated and co-localized with each other and with RAD51 at sites of stalled DNA replication forks. Hydroxyurea 43-54 P53 Homo sapiens 13-16 18224251-4 2008 In primary fibroblasts with mutations in the core complex FANCA protein, we discovered that basal expression and phosphorylation of ATM (ataxia telangiectasia mutated) and p53 induced by irradiation (IR) or mitomycin C (MMC) were upregulated. Mitomycin 207-218 P53 Homo sapiens 172-175 12641444-7 2003 Of this group, arsenic trioxide was the strongest inducer of cellular p53, while dimethylarsinic acid, iododimethylarsine, and sodium arsenite also caused p53 induction in a dose- and time-dependent manner. sodium arsenite 127-142 P53 Homo sapiens 155-158 12046074-1 2002 AIM: In hepatocellular carcinoma (HCC) prevalent areas of China, the point mutation of p53 exon7 is highly correlated with Hepatitis B virus(HBV) infection and aflatoxin B intake. Aflatoxin B1 160-171 P53 Homo sapiens 87-90 11864976-0 2002 The course of etoposide-induced apoptosis from damage to DNA and p53 activation to mitochondrial release of cytochrome c. Etoposide 14-23 P53 Homo sapiens 65-68 18224251-4 2008 In primary fibroblasts with mutations in the core complex FANCA protein, we discovered that basal expression and phosphorylation of ATM (ataxia telangiectasia mutated) and p53 induced by irradiation (IR) or mitomycin C (MMC) were upregulated. Mitomycin 220-223 P53 Homo sapiens 172-175 11864976-3 2002 Etoposide caused the phosphorylation of p53 within 6 h, an effect prevented by wortmannin, an inhibitor of DNA-dependent protein kinase (DNA-PK). Etoposide 0-9 P53 Homo sapiens 40-43 18191951-0 2008 Interferonalpha enhances etoposide-induced apoptosis in human osteosarcoma U2OS cells by a p53-dependent pathway. Etoposide 25-34 P53 Homo sapiens 91-94 11864976-4 2002 The activation of p53 by etoposide resulted in the up-regulation of the pro-apoptotic protein Bax, a result that was prevented by the protein synthesis inhibitor cycloheximide. Etoposide 25-34 P53 Homo sapiens 18-21 11980662-9 2002 Both inducible TS expression and the addition of exogenous thymidine (10 microM) blocked p53 and p21 induction by the antifolates but not by 5-FU in the M7TS90 cell line. Thymidine 59-68 P53 Homo sapiens 89-92 12619109-3 2003 In populations exposed to dietary aflatoxin B1 with liver cancer (AFB1) and ultraviolet (UV)-radiation with skin cancer, a single specific-looking TP53 mutation has been described in some of the tumors. Aflatoxin B1 34-46 P53 Homo sapiens 147-151 12609712-4 2003 Up-regulation of p53 coincided with accretion of 8-oxoguanine lesions. 8-hydroxyguanine 49-61 P53 Homo sapiens 17-20 18191951-4 2008 IFNalpha enhanced etoposide-induced growth inhibition and apoptosis in p53-wild U2OS cells but not p53-mutant MG63 cells in a dose- and time-dependent manner. Etoposide 18-27 P53 Homo sapiens 71-74 11934438-0 2002 Role of P53 functionality in the genotoxicity of metronidazole and its hydroxy metabolite. Metronidazole 49-62 P53 Homo sapiens 8-11 11948395-0 2002 Characterization of the p53-rescue drug CP-31398 in vitro and in living cells. CP 31398 40-48 P53 Homo sapiens 24-27 11948395-1 2002 The Pfizer compound CP-31398 has been reported to stabilize the core domain of the tumour suppressor p53 in vitro and be an effective anti-cancer drug by virtue of rescuing destabilized mutants of p53. CP 31398 20-28 P53 Homo sapiens 101-104 12468545-5 2003 After treatment with Vp16 or mitomycin C, control cells underwent apoptosis in a p53-dependent manner; however, overexpression of catalase inhibited this apoptosis. Etoposide 21-25 P53 Homo sapiens 81-84 12468545-5 2003 After treatment with Vp16 or mitomycin C, control cells underwent apoptosis in a p53-dependent manner; however, overexpression of catalase inhibited this apoptosis. Mitomycin 29-40 P53 Homo sapiens 81-84 12468545-6 2003 Basal levels as well as Vp16- or mitomycin C-stimulated levels of p53 and p21 protein were decreased in the catalase-overexpressing cells as compared with control cells; however, p53 mRNA levels were not decreased by catalase. Mitomycin 33-44 P53 Homo sapiens 66-69 11948395-1 2002 The Pfizer compound CP-31398 has been reported to stabilize the core domain of the tumour suppressor p53 in vitro and be an effective anti-cancer drug by virtue of rescuing destabilized mutants of p53. CP 31398 20-28 P53 Homo sapiens 197-200 18191951-9 2008 Thus we conclude that IFNalpha enhances etoposide-induced apoptosis in human osteosarcoma U2OS cells by a p53-dependent and caspase-activation pathway. Etoposide 40-49 P53 Homo sapiens 106-109 11948395-6 2002 CP-31398 also decreased sequence-specific DNA binding of wild-type p53 and His-273 mutant p53. CP 31398 0-8 P53 Homo sapiens 67-70 11948395-6 2002 CP-31398 also decreased sequence-specific DNA binding of wild-type p53 and His-273 mutant p53. CP 31398 0-8 P53 Homo sapiens 90-93 12680200-3 2003 Since many chemotherapeutic drugs induce p53-dependent apoptosis, we sought to investigate if CP-31398 would enhance chemosensitivity in human melanoma cells by stabilizing p53. CP 31398 94-102 P53 Homo sapiens 173-176 18245478-3 2008 In vitro treatment with etoposide only and in vivo treatment with either etoposide or mitoxantrone induces DNA damage, elevates expression (600-fold) and promotes nuclear translocation of p53, and results in apoptosis of leukemic clam hemocytes. Etoposide 24-33 P53 Homo sapiens 188-191 13129816-5 2003 As(2)O(3)-induced apoptosis was associated with upregulation of p53 and caspase 3, whereas NaAsO(2)-induced apoptosis was associated with p53 upregulation. sodium arsenite 91-99 P53 Homo sapiens 138-141 13129817-0 2003 Apoptosis mediated by phosphatidylcholine-specific phospholipase C is associated with cAMP, p53 level, and cell-cycle distribution in vascular endothelial cells. Phosphatidylcholines 22-41 P53 Homo sapiens 92-95 14622914-6 2003 Treatments that modified the alkaloid-induced Ca2+ influx including tetrodotoxin or Ca2+ removal, prevented either veratridine-induced cell death or p53 immunoreactivity. Tetrodotoxin 68-80 P53 Homo sapiens 149-152 11948395-7 2002 CP-31398 had a non-specific toxic effect independent of mutant p53 expression in several cell lines carrying Tet-regulated mutant p53. CP 31398 0-8 P53 Homo sapiens 130-133 11948395-7 2002 CP-31398 had a non-specific toxic effect independent of mutant p53 expression in several cell lines carrying Tet-regulated mutant p53. tetramethylenedisulfotetramine 109-112 P53 Homo sapiens 130-133 11948395-8 2002 CP-31398 caused a small increase in MDM-2 expression and a more pronounced p53-independent increase in Bax expression. CP 31398 0-8 P53 Homo sapiens 75-78 11948395-9 2002 CP-31398 did, however, induce the PAb1620 epitope (characteristic of native p53) in cells expressing His-175 mutant p53. CP 31398 0-8 P53 Homo sapiens 76-79 11948395-9 2002 CP-31398 did, however, induce the PAb1620 epitope (characteristic of native p53) in cells expressing His-175 mutant p53. CP 31398 0-8 P53 Homo sapiens 116-119 11948395-10 2002 This was prevented by cycloheximide, suggesting that any stabilizing action of CP-31398 would have to be on newly synthesized p53. CP 31398 79-87 P53 Homo sapiens 126-129 18245478-3 2008 In vitro treatment with etoposide only and in vivo treatment with either etoposide or mitoxantrone induces DNA damage, elevates expression (600-fold) and promotes nuclear translocation of p53, and results in apoptosis of leukemic clam hemocytes. Etoposide 73-82 P53 Homo sapiens 188-191 11781135-0 2002 Activation of Erk1/Erk2 and transiently increased p53 levels together may account for p21 expression associated with phorbol ester-induced transient growth inhibition in HepG2 cells. Phorbol Esters 117-130 P53 Homo sapiens 50-53 11781135-5 2002 Either the activation of PKC with phorbol ester or the addition of BIM to cells growing in serum induced a rapid but transient increase of p53 levels, which preceded growth inhibition. Phorbol Esters 34-47 P53 Homo sapiens 139-142 18245478-4 2008 Pretreatment with wheat germ agglutinin followed by etoposide treatment induces DNA damage and elevates p53 expression (893-fold) but does not overcome cytoplasmic sequestration of p53 or induce apoptosis. Etoposide 52-61 P53 Homo sapiens 104-107 11809417-9 2002 Pretreatment with pyrrolidine dithiocarbamate (PDTC), an inhibitor of the redox sensitive transcription factor NF-kappa B, abrogated the increased expression of p53 protein in response to H(2)O(2), and enhanced cell survival. pyrrolidine dithiocarbamic acid 18-45 P53 Homo sapiens 161-164 12471108-2 2002 This repression is independent of the intrinsic transcriptional activity of p53 and is mediated by the Tax-responsive CD28RE-3"-12-O-tetradecanoylphorbol-13-acetate response element (AP1) element of the IL-2 promoter. cd28re-3"-12-o-tetradecanoylphorbol-13-acetate 118-164 P53 Homo sapiens 76-79 11809417-9 2002 Pretreatment with pyrrolidine dithiocarbamate (PDTC), an inhibitor of the redox sensitive transcription factor NF-kappa B, abrogated the increased expression of p53 protein in response to H(2)O(2), and enhanced cell survival. pyrrolidine dithiocarbamic acid 47-51 P53 Homo sapiens 161-164 18043262-6 2008 CP-31398 was the first small molecule identified with the ability to restore the wild-type conformation to mutant p53. CP 31398 0-8 P53 Homo sapiens 114-117 12454767-10 2002 In conclusion, tumour stage, node stage, p53 gene status, and bcl-2 expression are independent predictors of tumour response to platin-fluorouracil in patients with squamous-cell carcinomas of the head and neck. platin-fluorouracil 128-147 P53 Homo sapiens 41-44 12507920-8 2002 These results are also consistent with the hypothesis that BP (PAH) induce G:C to T:A transversion mutations in the hotspot codons of the p53 tumor suppressor gene and are thus involved in malignant transformation of the lung tissue of smokers. p-Aminohippuric Acid 63-66 P53 Homo sapiens 138-141 18097557-2 2008 Trichostatin A (TSA), ITF2357 and suberoylanilide hydroxamic acid (SAHA), which were very effective agents, caused apoptotic effects after a lag phase of 12-16 h. In order to elucidate the mechanism of HDACIs action in HepG2 cells we have studied the effects of TSA, ITF2357 and SAHA on acetylation of p53 and histones H2A, H2B, H3 and H4. trichostatin A 0-14 P53 Homo sapiens 302-305 12402298-6 2002 With formamidopyrimidine-DNA glycosylase treatment, N-OH-AF induced cleavage at guanine residues, especially of the ACG sequence complementary to codon 273, a well-known hot spot of the p53 gene. acceleratory factor from growth hormone 116-119 P53 Homo sapiens 186-189 11818510-6 2002 Competition for coactivator CREB binding protein could not entirely account for the repression but trichostatin A, an inhibitor of histone deacetylase activity, could reverse p53-mediated repression of HNF4alpha1. trichostatin A 99-113 P53 Homo sapiens 175-178 11818510-7 2002 In contrast, p53-mediated repression of transcriptional activation of the same promoter by another transcriptional activator, CCAAT/enhancer-binding protein-alpha, could not be reversed by the addition of trichostatin A. trichostatin A 205-219 P53 Homo sapiens 13-16 11821962-5 2002 Mutant p53 stimulates recombination induced by the replication elongation inhibitors (aphidicolin, hydroxyurea and Ara-C) but is without effect on recombination induced by the initiation inhibitors (mimosine and ciclopirox olamine). Hydroxyurea 99-110 P53 Homo sapiens 7-10 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Etoposide 156-165 P53 Homo sapiens 32-35 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Etoposide 156-165 P53 Homo sapiens 237-240 12421475-6 2002 The expression of G1 S checkpoint related proteins, p53, p21/WAF1, and p16/INK4, were up-regulated after MGC 803 cells were treated with isoverbascoside 20 micromol/L for 4-8 h. Contrarily, the expression of C-myc protein was suppressed after 8 h treatment. isoacteoside 137-152 P53 Homo sapiens 52-55 11791171-5 2002 In PA1-neo cells with wild-type p53, the activation of caspases including caspases 9, 8, 7 and 3 and cleavage of PARP were detected following adriamycin or etoposide treatment, whereas no such changes were observed in PA1-E6 cells whose p53 is degraded, suggesting that loss of p53 impairs caspase activation. Etoposide 156-165 P53 Homo sapiens 237-240 18097557-2 2008 Trichostatin A (TSA), ITF2357 and suberoylanilide hydroxamic acid (SAHA), which were very effective agents, caused apoptotic effects after a lag phase of 12-16 h. In order to elucidate the mechanism of HDACIs action in HepG2 cells we have studied the effects of TSA, ITF2357 and SAHA on acetylation of p53 and histones H2A, H2B, H3 and H4. trichostatin A 16-19 P53 Homo sapiens 302-305 18032786-0 2007 The increase of cell-membranous phosphatidylcholines containing polyunsaturated fatty acid residues induces phosphorylation of p53 through activation of ATR.

Fatty Acids, Unsaturated 64-90 P53 Homo sapiens 127-130 12642691-2 2002 Here we demonstrated that treatment of SW-1736 cells with sub-cytotoxic concentrations of FR901228, a histone deacetylase (HDAC) inhibitor, results in marked induction of p53 mRNA and protein. romidepsin 90-98 P53 Homo sapiens 171-174 12642691-3 2002 The p53 induced by FR901228 was functional as evidenced by mdm-2 and p21 transactivation, and its further accumulation following DNA damage by doxorubicin. romidepsin 19-27 P53 Homo sapiens 4-7 18032786-8 2007 The time course of phosphorylation of Ser15 in p53 correlates with increasing levels of PCs containing polyunsaturated fatty acids. Fatty Acids, Unsaturated 103-130 P53 Homo sapiens 47-50 12181752-2 2002 Here we report that cerulenin is an effective inducer of apoptosis in different wild-type p53 and mutant p53 tumor cell lines, whereas normal human keratinocytes and fibroblasts are resistant to the apoptotic effect. Cerulenin 20-29 P53 Homo sapiens 90-93 17669439-6 2007 Elevated expressions of p53 and p21 with a decrease in cyclin-D level supported the observation on cell cycle arrest following TSA treatment. trichostatin A 127-130 P53 Homo sapiens 24-27 12181752-2 2002 Here we report that cerulenin is an effective inducer of apoptosis in different wild-type p53 and mutant p53 tumor cell lines, whereas normal human keratinocytes and fibroblasts are resistant to the apoptotic effect. Cerulenin 20-29 P53 Homo sapiens 105-108 11964141-0 2002 Copper uptake is required for pyrrolidine dithiocarbamate-mediated oxidation and protein level increase of p53 in cells. pyrrolidine dithiocarbamic acid 30-57 P53 Homo sapiens 107-110 11964141-7 2002 Bathocuproinedisulphonic acid as well as the hydroxyl radical scavenger d-mannitol inhibited the PDTC-dependent increase in p53 protein and oxidation. Hydroxyl Radical 45-61 P53 Homo sapiens 124-127 12462448-5 2002 Observations that mutations in gene p53 appear under conditions of occupational and environmental exposures to chemical and physical carcinogens, such as vinyl chloride, radon, or aflatoxin B1, have proved to be of enormous importance for the occupational and environmental health. Aflatoxin B1 180-192 P53 Homo sapiens 36-39 11741290-0 2001 Camptothecin and Zeocin can increase p53 levels during all cell cycle stages. Camptothecin 0-12 P53 Homo sapiens 37-40 11741290-7 2001 The p53 induced by both drugs was able to bind to DNA; however, only the p53 induced by camptothecin was phosphorylated at serine-392. Camptothecin 88-100 P53 Homo sapiens 4-7 11741290-7 2001 The p53 induced by both drugs was able to bind to DNA; however, only the p53 induced by camptothecin was phosphorylated at serine-392. Camptothecin 88-100 P53 Homo sapiens 73-76 12118068-6 2002 Fibroblasts from Alzheimer"s disease patients also have a profound impairment in the H(2)O(2)-activated, p53-dependent pathway, which results in a lack of activation of p53 or p53-target genes, including p21, GADD45 and bax. h(2)o 85-90 P53 Homo sapiens 105-108 18088187-10 2007 Moreover, sustained phosphorylation of Chk1 in the presence of staurosporine and UCN-01 is strongly related to phosphorylation of p53. Staurosporine 63-76 P53 Homo sapiens 130-133 17906315-10 2007 In conclusion, this study demonstrated that sodium arsenite is genotoxic to uroepithelial cells in vitro, and that it will induce expression of mutant p53 and COX-2 proteins, indicating a possible key event in carcinogenesis. sodium arsenite 44-59 P53 Homo sapiens 151-154 12492119-4 2002 Rottlerin, a PKCdelta inhibitor that prevents CP-induced proteolytic activation of PKCdelta, caused an accumulation of p53 in HeLa cells when treated in conjunction with CP, but it had no additional effect in HeLa/CP cells. rottlerin 0-9 P53 Homo sapiens 119-122 11704535-5 2001 The CS-induced apoptosis was associated with increased oxidative stress, Bax protein accumulation, mitochondrial dysfunction, and mitochondrial cytochrome c release but was independent of p53, Fas, and caspase activation. Cesium 4-6 P53 Homo sapiens 188-191 11698292-9 2001 In contrast, in vitro treatment with cytarabine and etoposide induced p53 protein, CD95 receptor expression, CD95 sensitivity, and CD95 receptor-ligand interaction in stimulated cycling lymphocytes, but no such induction was seen in resting cells. Etoposide 52-61 P53 Homo sapiens 70-73 12143201-15 2002 The expression of p53 oncogene and the PCNA were determined by immunohistochemical method, using avidin-biotin method (DAKO). avidin-biotin 97-110 P53 Homo sapiens 18-21 17904593-3 2007 Our results suggest that the protective effects of esculin (10(-7), 10(-6) and 10(-5) M) on DA-induced cytotoxicity may be ascribed to its anti-oxidative properties by reducing ROS level, and its anti-apoptotic effect via protecting mitochondrion membrane potential (DeltaPsim), enhancing superoxide dismutaese (SOD) activity and reduced glutathione (GSH) levels, and regulating P53, Bax and Bcl-2 expression. Esculin 51-58 P53 Homo sapiens 379-382 12187957-5 2002 Immunohistochemical variables differed between various subsets: the number of p53-positive tumors was found to be prevailed among the PGB, whereas the number of tumors with EGFR and mdm2 positivity was significantly greater in SGB. Prostaglandins B 134-137 P53 Homo sapiens 78-81 12048243-3 2002 DNA damage induced by camptothecin, which activates the tumor suppressor p53, was found to activate GSK3beta.

Etoposide 20-29 P53 Homo sapiens 0-3 11593403-3 2001 In contrast, agents that inhibit the elongation phase of transcription, such as UV light, camptothecin or actinomycin D, induced the accumulation of nuclear p53 proteins that were modified at both of these sites. Camptothecin 90-102 P53 Homo sapiens 157-160 19383392-2 2007 Here we investigate the role of p53 in etoposide-induced apoptosis. Etoposide 39-48 P53 Homo sapiens 32-35 12036943-7 2002 Subtoxic concentrations of camptothecin (which stabilizes topoisomerase I cleavage complexes, mediating nonhomologous recombination) produced a dose-dependent increase in PALA(R) colonies, and combining expression of mutant p53 with exposure to camptothecin produced a greater than additive increase in PALA(R) colony formation. Camptothecin 27-39 P53 Homo sapiens 224-227 19383392-4 2007 Etoposide treatment results in a rapid and extensive induction of apoptosis and leads to a further increase in p53 and PUMA expression as well as Bax processing. Etoposide 0-9 P53 Homo sapiens 111-114 11551522-4 2001 Wild-type p53 containing WMN Burkitt"s lymphoma cells and wild type p53-deficient CA46 exhibited similar sensitivities to miltefosine. miltefosine 122-133 P53 Homo sapiens 10-13 19383392-6 2007 hESC stably transduced with p53 shRNA display 80% reduction of endogenous p53 and exhibit an 80% reduction in etoposide-induced apoptosis accompanied by constitutive downregulation of Bax and an attenuated upregulation of PUMA. Etoposide 110-119 P53 Homo sapiens 28-31 19383392-8 2007 Our study demonstrates that p53 is required for etoposide-induced apoptosis of hESC and reveals, at least in part, the molecular mechanism of DNA-damage-induced apoptosis in hESC. Etoposide 48-57 P53 Homo sapiens 28-31 12076704-3 2002 Mutational screening of the coding region of TP53 revealed an A>T transversion in codon 144 of exon 5 (CAG>CTG, Gln>Leu) in the germline of one of the three affected members, with loss of heterozygosity (LOH) in the tumour tissue. Glutamine 112-115 P53 Homo sapiens 45-49 17894897-8 2007 Etoposide increased p53 activity in all cell lines while hypoxia alone decreased it only in HepG2 cells. Etoposide 0-9 P53 Homo sapiens 20-23 12011430-1 2002 A G to T mutation has been observed at the third position of codon 249 of the p53 tumor-suppressor gene in over 50% of the hepatocellular carcinoma cases associated with high exposure to aflatoxin B(1) (AFB(1)). Aflatoxin B1 187-198 P53 Homo sapiens 78-81 11507071-9 2001 Loss of p53 function was selectively achieved by transduction of human papillomavirus 16 E6 (which degrades p53) into two drug-sensitive neuroblastoma cell lines with intact p53, causing high-level drug resistance to L-PAM, carboplatin, and etoposide. Etoposide 241-250 P53 Homo sapiens 8-11 11997093-5 2002 Expression of CDM2 was shown to be transcriptionally upregulated in the primary CEF cells where p53 was activated by either mitomycin C treatment or by the exogenous transfection of the chicken p53 cDNA. Mitomycin 124-135 P53 Homo sapiens 96-99 17894897-10 2007 Using low density DNA arrays to detect the expression of genes involved in the regulation of apoptosis, etoposide and hypoxia were shown to each influence the expression of numerous genes, many of the ones influenced by etoposide being p53 target genes. Etoposide 104-113 P53 Homo sapiens 236-239 11431359-14 2001 hMLH1-dependent responses to fluoropyrimidine treatment, which may involve the action of p53 and the formation of DSBs, clearly have clinical relevance for the use of this class of drugs in the treatment of tumors with MMR deficiencies. 2-fluoropyrimidine 29-45 P53 Homo sapiens 89-92 17894897-10 2007 Using low density DNA arrays to detect the expression of genes involved in the regulation of apoptosis, etoposide and hypoxia were shown to each influence the expression of numerous genes, many of the ones influenced by etoposide being p53 target genes. Etoposide 220-229 P53 Homo sapiens 236-239 17894897-12 2007 CONCLUSION: These results evidenced that there was a striking parallelism between the effect of hypoxia on the etoposide-induced p53 stabilization as well as p53 target gene expression and its effect on the etoposide-induced apoptosis according to the cell type. Etoposide 111-120 P53 Homo sapiens 129-132 11929951-4 2002 METHODS: Proliferation and apoptosis were assessed in a panel of NSCLC cell lines that vary in the expression of the growth-regulating proteins p53, pRb, and K-Ras treated with a clinically relevant dose of FK228 (25 ng/mL). romidepsin 207-212 P53 Homo sapiens 144-147 17894897-12 2007 CONCLUSION: These results evidenced that there was a striking parallelism between the effect of hypoxia on the etoposide-induced p53 stabilization as well as p53 target gene expression and its effect on the etoposide-induced apoptosis according to the cell type. Etoposide 207-216 P53 Homo sapiens 129-132 11929951-6 2002 RESULTS: FK228 treatment inhibited growth and induced apoptosis in NSCLC cells expressing wild-type or mutant p53. romidepsin 9-14 P53 Homo sapiens 110-113 11929951-7 2002 FK228 treatment led to altered expression of cyclin A, cyclin E, and p21, and to reduced expression of mutant, but not wild-type, p53. romidepsin 0-5 P53 Homo sapiens 130-133 11479920-10 2001 Examination of the signaling pathways that mediate 2-ME-induced apoptosis showed reduction in the level of p53 expression and its DNA-binding activity. 2-Methoxyestradiol 51-55 P53 Homo sapiens 107-110 17894897-12 2007 CONCLUSION: These results evidenced that there was a striking parallelism between the effect of hypoxia on the etoposide-induced p53 stabilization as well as p53 target gene expression and its effect on the etoposide-induced apoptosis according to the cell type. Etoposide 207-216 P53 Homo sapiens 158-161 11479920-11 2001 Given the fact that p53 mutations are common in patients with metastatic prostate cancer, our finding that 2-ME-mediated growth inhibition of human prostate cancer cells occurred in a p53-independent manner has considerable clinical significance. 2-Methoxyestradiol 107-111 P53 Homo sapiens 20-23 11929951-9 2002 FK228 treatment also inhibited the binding of mutant p53 and Raf-1 to Hsp90; this inhibition was associated with acetylation of Hsp90. romidepsin 0-5 P53 Homo sapiens 53-56 17767476-9 2007 Unlike PPI alone, rofecoxib + PPI was associated with an increase in the apoptotic cell index, a decrease in p53 cell staining and VEGF expression in mucosal vessels. rofecoxib 18-27 P53 Homo sapiens 109-112 11960380-5 2002 Surprisingly, we found that hydroxyurea-treated BLM-deficient cells exhibit an intact S phase arrest, proper recovery from the S phase arrest, and intact p53 and p21 responses. Hydroxyurea 28-39 P53 Homo sapiens 154-157 11935300-6 2002 RESULTS: Ex vivo chemosensitivity testing showed that tumors with p53 mutations were significantly more resistant to the cyclophosphamide/etoposide/epirubicin regimen than with normal p53 gene ( P = 0.012). Etoposide 138-147 P53 Homo sapiens 66-69 11841447-4 2002 The p53-transfected cells showed a decreased ability to arrest in G2 and an increase in apoptosis in response to etoposide treatment, relative to the control mock-transfected cells. Etoposide 113-122 P53 Homo sapiens 4-7 11841447-5 2002 p53-transfected and control cells were treated with etoposide and trapped at mitosis with nocodazole. Etoposide 52-61 P53 Homo sapiens 0-3 11278647-5 2001 A differential modulation of the p53 target gene (p21/WAF, bax, thrombospondin-1, and mdm-2) transcription was observed upon Mts1 induction in tet-inducible cell lines expressing wild type p53. tetramethylenedisulfotetramine 143-146 P53 Homo sapiens 33-36 11278647-5 2001 A differential modulation of the p53 target gene (p21/WAF, bax, thrombospondin-1, and mdm-2) transcription was observed upon Mts1 induction in tet-inducible cell lines expressing wild type p53. tetramethylenedisulfotetramine 143-146 P53 Homo sapiens 189-192 11406538-10 2001 A more striking association was found in G:C to A:T transitions in non-CpG dinucleotides; 71% (12 of 17) of the total non-CpG transition mutations in p53 were observed in MGMT aberrantly methylated tumors (Fischer"s exact test, two-tailed; P = 0.008). Dinucleoside Phosphates 75-88 P53 Homo sapiens 150-153 11482451-8 2001 In the TP53 mutant cell lines, DU145 and BM1604, dose enhancement factors (EFs) were found to be in the region of 4.20 for cisplatin, 3.70 for vinblastine, and 3.20 for etoposide. Etoposide 169-178 P53 Homo sapiens 7-11 11482451-9 2001 In the TP53 wild-type cell line, LNCaP, the enhancement factors were low and in the region of 1.20 for cisplatin, vinblastine and etoposide. Etoposide 130-139 P53 Homo sapiens 7-11 11841447-6 2002 The mitotic index of p53-transfected cells was higher than that of the control cells, which suggests that p53 abrogates the G2 checkpoint response to etoposide treatment in K562 cells. Etoposide 150-159 P53 Homo sapiens 21-24 11841447-6 2002 The mitotic index of p53-transfected cells was higher than that of the control cells, which suggests that p53 abrogates the G2 checkpoint response to etoposide treatment in K562 cells. Etoposide 150-159 P53 Homo sapiens 106-109 11841447-7 2002 We found that the expression of the cell cycle checkpoint protein Chk1 was reduced in the etoposide-treated p53-transfected cells by 24 h, and this correlated with a reduction in the extent of etoposide-induced phosphorylation of CDK1 at tyrosine 15 (Y15). Etoposide 90-99 P53 Homo sapiens 108-111 17876055-6 2007 Mechanistic studies suggested roles for Akt, GSK-3beta, MDM2, and p53 in enterolactone-dependent apoptosis. 2,3-bis(3'-hydroxybenzyl)butyrolactone 73-86 P53 Homo sapiens 66-69 11791186-5 2002 The inhibitory effect of wild type p53 was undetectable in the presence of trichostatin A, suggesting the involvement of histone deacetylation in negative regulation of PSA promoter activity. trichostatin A 75-89 P53 Homo sapiens 35-38 11279186-3 2001 DNA interactions of active wild-type human p53 protein with DNA fragments and oligodeoxyribonucleotide duplexes modified by antitumor cisplatin and its clinically ineffective trans isomer (transplatin) were investigated by using a gel mobility shift assay. Oligodeoxyribonucleotides 78-102 P53 Homo sapiens 43-46 11316564-6 2001 In terms of changes in expression of p53-related proteins, increase in expression of Bax and decrease in that of Bcl-2 were observed in TE-2 but not in TE-1, suggesting that the main mode of cell death induced by genistein in a cell line with wild type p53 differed from that with mutant p53. Genistein 213-222 P53 Homo sapiens 37-40 11316564-6 2001 In terms of changes in expression of p53-related proteins, increase in expression of Bax and decrease in that of Bcl-2 were observed in TE-2 but not in TE-1, suggesting that the main mode of cell death induced by genistein in a cell line with wild type p53 differed from that with mutant p53. Genistein 213-222 P53 Homo sapiens 253-256 17286201-3 2007 LY294002 potentiated expression of p21WAF1/Cip1 via a p53-independent mechanism and did not affect mitogen activated protein kinase (MAPK) activation. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 0-8 P53 Homo sapiens 54-57 11316564-6 2001 In terms of changes in expression of p53-related proteins, increase in expression of Bax and decrease in that of Bcl-2 were observed in TE-2 but not in TE-1, suggesting that the main mode of cell death induced by genistein in a cell line with wild type p53 differed from that with mutant p53. Genistein 213-222 P53 Homo sapiens 253-256 11300786-2 2001 Wild-type p53 was basally expressed after baculovirus infection while a parallel preparation was treated with the phosphatase inhibitor okadaic acid during the terminal stages of expression to create a hyperphosphorylated form of p53 known for its higher DNA binding and transcriptional activation. Okadaic Acid 136-148 P53 Homo sapiens 230-233 11400161-9 2001 Induction of endogenous p53 expression by etoposide also inhibited promoter activity and minigene inducibility. Etoposide 42-51 P53 Homo sapiens 24-27 11756188-3 2002 CDDO-Me decreased the viability of leukemic cell lines, including multidrug resistant (MDR)-1-overexpressing, p53(null) HL-60-Dox and of primary AML cells, and it was 3- to 5-fold more active than CDDO. bardoxolone methyl 0-7 P53 Homo sapiens 110-113 11756188-10 2002 In conclusion, CDDO-Me is an MDR-1- and a p53-independent compound that exerts strong antiproliferative, apoptotic, and differentiating effects in myeloid leukemic cell lines and in primary AML samples when given in submicromolar concentrations. bardoxolone methyl 15-22 P53 Homo sapiens 42-45 12429914-5 2002 BL also inhibited the p53-dependent increase of p21 protein expression in cells exposed to the DNA damag-ing agent etoposide, and favored a greater G2/M arrest as compared to the non-BL exposed cells. Etoposide 115-124 P53 Homo sapiens 22-25 11400165-6 2001 In elucidating these findings, it was determined that after 2 days of incubation with genistein, MCF-7 but not MDA-MB-231 cells, had significantly higher levels of p53. Genistein 86-95 P53 Homo sapiens 164-167 17515610-5 2007 p21CIP1 was found to be a critical p53 target for arrest induced by hydroxyurea or aphidicolin, but not etoposide, as judged by the ability of p21CIP1 suppression to mimic the effects of p53 disruption. Hydroxyurea 68-79 P53 Homo sapiens 35-38 11400165-8 2001 Levels of p21 increased in both of the genistein-treated cell lines, suggesting that p21 gene expression was activated but in a p53-independent manner, whereas no significant changes in levels of the pro-apoptotic protein, Bax, were found. Genistein 39-48 P53 Homo sapiens 128-131 11862321-4 2002 Cells with different states of p53 expression, either endogenously or ectopically, were exposed to hydroxyurea to induce an imbalance of cellular dNTP pools and cause replication errors. Hydroxyurea 99-110 P53 Homo sapiens 31-34 11862321-6 2002 Incubation of cells with hydroxyurea induced a similar degree of dNTP pool imbalance in each cell line, but caused significantly more mutations in cells lacking p53 protein expression. Hydroxyurea 25-36 P53 Homo sapiens 161-164 11594760-10 2001 Exploration of p53 fluorescence using potassium iodide as a quencher confirmed that these fluorophores are already substantially quenched in the native structure, and this quenching is not relieved during protein unfolding. Potassium Iodide 38-54 P53 Homo sapiens 15-18 17515610-5 2007 p21CIP1 was found to be a critical p53 target for arrest induced by hydroxyurea or aphidicolin, but not etoposide, as judged by the ability of p21CIP1 suppression to mimic the effects of p53 disruption. Hydroxyurea 68-79 P53 Homo sapiens 187-190 11556844-1 2001 The present study was performed to gain insight into the role of p53 on the cytotoxicity of tubulin-binding agents (TBA) on cancer cells. tba 116-119 P53 Homo sapiens 65-68 11556844-9 2001 We conclude that the p53 status of cancer cells influences their sensitivity to TBA cytotoxicity. tba 80-83 P53 Homo sapiens 21-24 11346470-5 2001 Treatment with etoposide increased expression of p53 and decreased expression of Bcl-X(L) in U-373MG cells which harbored mutant p53. Etoposide 15-24 P53 Homo sapiens 49-52 11346470-5 2001 Treatment with etoposide increased expression of p53 and decreased expression of Bcl-X(L) in U-373MG cells which harbored mutant p53. Etoposide 15-24 P53 Homo sapiens 129-132 17515610-6 2007 Suppression of Rad51 expression, required for homologous recombination repair, blocked the ability of mutant p53 to antagonize arrest induced by etoposide, but not aphidicolin. Etoposide 145-154 P53 Homo sapiens 109-112 17515610-8 2007 However, when replication stress is associated with DNA strand breaks (such as with etoposide), up-regulation of homologous recombination repair in response to p53 disruption becomes important. Etoposide 84-93 P53 Homo sapiens 160-163 11283670-4 2001 A specific HDAC inhibitor, trichostatin A (TSA), upregulated p53 and von Hippel-Lindau expression and downregulated hypoxia-inducible factor-1alpha and vascular endothelial growth factor. trichostatin A 27-41 P53 Homo sapiens 61-64 11431470-6 2001 In addition, treatment of cells with the PKC activator phorbol ester stimulated the ubiquitination of p53 and reduced its ability to accumulate after stress. Phorbol Esters 55-68 P53 Homo sapiens 102-105 11283670-4 2001 A specific HDAC inhibitor, trichostatin A (TSA), upregulated p53 and von Hippel-Lindau expression and downregulated hypoxia-inducible factor-1alpha and vascular endothelial growth factor. trichostatin A 43-46 P53 Homo sapiens 61-64 17699715-4 2007 Etoposide-selective cytotoxicity in the Akt-myr-transduced cells was shown to be caused by nonapoptotic cell death and occurred in a p53-independent manner. Etoposide 0-9 P53 Homo sapiens 133-136 11313875-5 2001 Nuclear accumulation of p53 was induced in NB cells using substances which disturb p53"s tertiary structure at its zinc finger motif, or by treatment with mitomycin C. Mitomycin 155-166 P53 Homo sapiens 24-27 11313875-7 2001 Even though p53 showed DNA-binding capability after mitomycin C treatment of NB cells, the target gene products MDM2 and p21(WAF1,CIP1,SDI1) were not synthesized and no p53 transactivating activity measured in a reporter gene assay. Mitomycin 52-63 P53 Homo sapiens 12-15 11313880-2 2001 Treatment of human glioma cells with etoposide caused apoptosis only in cells expressing functional p53. Etoposide 37-46 P53 Homo sapiens 100-103 11313880-3 2001 p53 activation was followed by the formation of reactive oxygen species (ROS), superoxide anion (O2-*) measured by hydroethidium oxidation into ethidium and hydrogen peroxide (H2O2) measured by oxidation of 2",7"-dichlorofluorescin (DCFH) into 2",7"-dichlorofluorescein (DCF), which was accompanied with ceramide generation through the activation of neutral, but not acid, sphingomyelinase. DCFH 233-237 P53 Homo sapiens 0-3 11526514-8 2001 Our data revealed a relationship between chromosome 16q homozygous deletions and R249S p53 mutations in tumors where the patient had been exposed to aflatoxin B1 (P=0.002). Aflatoxin B1 149-161 P53 Homo sapiens 87-90 11375983-3 2001 When ectopic wild-type p53 expression was induced to a physiologically relevant level in "tet-off" cultured cells in which p53 expression was tightly regulated by tetracycline, it was found that POLD1 steady-state mRNA was repressed by about 65%. tetramethylenedisulfotetramine 90-93 P53 Homo sapiens 23-26 11585319-8 2001 We further obtained evidence of the upregulation of the intracellular apoptotic signalling cascade, represented by bcl-2 and bax, the transcription factor p53 and the active form of caspase 3, after pretreatment with mitomycin C. Mitomycin 217-228 P53 Homo sapiens 155-158 17555331-3 2007 First, a rapid and direct incorporation of biotinylated GSH or GSSG into the purified recombinant p53 protein was observed. Glutathione Disulfide 63-67 P53 Homo sapiens 98-101 11462153-11 2001 Western blot analysis of p53 and p21 revealed a gradual increase in the level of these proteins when RPE cells were exposed to increasing concentrations of MMC. Mitomycin 156-159 P53 Homo sapiens 25-28 17555331-7 2007 When tumor cells treated with camptothecin or cisplatin were subsequently exposed to glutathione-enhancing agents, p53 underwent dethiolation accompanied by detectable increases in the level of p21waf1 expression, relative to the DNA-damaging drugs alone. Camptothecin 30-42 P53 Homo sapiens 115-118 17555331-9 2007 Biotinylated maleimide also reacted rapidly with Cys141, implying that this is the most reactive cysteine on the p53 surface. biotinylated maleimide 0-22 P53 Homo sapiens 113-116 11438577-3 2001 Previous evidence has shown that the death of embryonic cortical neurons treated with the DNA-damaging agent camptothecin is dependent on the tumor suppressor p53 and cyclin-dependent kinase (CDK) activity and that the inhibition of either pathway alone leads to enhanced and prolonged survival. Camptothecin 109-121 P53 Homo sapiens 159-162 21603516-1 2007 OBJECTIVE: We have previously reported that oligodeoxyribonucleotides, designed to bind in a triplex fashion to a specific p53 binding site homology, inhibit the proliferation of colon cancer cells in vitro and in vivo. Oligodeoxyribonucleotides 44-69 P53 Homo sapiens 123-126 11457508-4 2001 Here we demonstrate increased expression and co-localization of p53 and Mdm2 in the nuclei of degenerating neurons following treatment with either the excitotoxin, kainic acid, or the topoisomerase I inhibitor, camptothecin. Camptothecin 211-223 P53 Homo sapiens 64-67 11223035-3 2001 In this report, the DNA alkylating agents mitomycin C (MMC) and methylmethane sulfonate (MMS), as well as UV radiation, stabilized p53 in a manner independent of phosphorylation in p53 N-terminus. Mitomycin 42-53 P53 Homo sapiens 131-134 11223035-3 2001 In this report, the DNA alkylating agents mitomycin C (MMC) and methylmethane sulfonate (MMS), as well as UV radiation, stabilized p53 in a manner independent of phosphorylation in p53 N-terminus. Mitomycin 55-58 P53 Homo sapiens 131-134 11159535-5 2001 Results show that the mdm2 antisense oligodeoxynucleotide induces apoptosis of cells that express a high or low level of MDM2 protein, only if they contain wild-type p53. Oligodeoxyribonucleotides 37-57 P53 Homo sapiens 166-169 17258428-6 2007 A screening study on 31 metal compounds, showed that the classified human carcinogens (NaAsO2, CdSO4 .8H2O, Na2CrO4 .4H2O, MnCl2, (NH4)2PtCl6) significantly increased cytotoxicity in p53-expressing cells compared to non-expressing cells, suggesting that their cytotoxicity was p53-mediated. cdso4 .8h2o 95-106 P53 Homo sapiens 183-186 11159535-7 2001 Finally, the p53 antisense oligodeoxynucleotide, which inhibits the expression of wild-type p53, also induces a decrease of the MDM2 level in cells, whether or not they overexpress this protein, and causes apoptosis of these cells. Oligodeoxyribonucleotides 27-47 P53 Homo sapiens 13-16 11159535-7 2001 Finally, the p53 antisense oligodeoxynucleotide, which inhibits the expression of wild-type p53, also induces a decrease of the MDM2 level in cells, whether or not they overexpress this protein, and causes apoptosis of these cells. Oligodeoxyribonucleotides 27-47 P53 Homo sapiens 92-95 11172593-5 2001 Upon DNA damage by treatment with mitomycin C the DNA-binding activity was increased, as known for cells with wild-type p53. Mitomycin 34-45 P53 Homo sapiens 120-123 11433418-8 2001 PEAZ-1 respond to ocadaic acid, a pro-apoptotic agent, by expression of p53. Okadaic Acid 18-30 P53 Homo sapiens 72-75 11418138-1 2001 This paper studies the cytotoxic effect induced by the topoisomerase I inhibitor camptothecin in human osteosarcoma Saos-2 cells, which lack p53 and contain a non-functional form of the product of the retinoblastoma gene, pRb. Camptothecin 81-93 P53 Homo sapiens 141-144 11498763-12 2001 In addition, we determined the effects of DNA damage produced by the DNA topoisomerase II inhibitor etoposide on wild-type p53 transfected lymphoma cells. Etoposide 100-109 P53 Homo sapiens 123-126 11313973-9 2001 Moreover, the enhancement of hyperploid formation by staurosporine was also blocked by p53-dependent G1 checkpoint.

Teniposide 71-81 P53 Homo sapiens 22-25 11042688-2 2000 Although all cell lines contain the same p53 mutations at codons 175 (Arg-->His) and 248 (Arg-->Gln), the constitutive levels of p53 were progressively increased with the resistance of the cells to teniposide. Glutamine 102-105 P53 Homo sapiens 135-138 11042688-2 2000 Although all cell lines contain the same p53 mutations at codons 175 (Arg-->His) and 248 (Arg-->Gln), the constitutive levels of p53 were progressively increased with the resistance of the cells to teniposide. Teniposide 204-214 P53 Homo sapiens 135-138 11042688-8 2000 Specifically, while the mutant p53 was phosphorylated at serine-15 in response to ionizing radiation in all these cell lines, mutant p53 induction in response to teniposide or ionizing radiation and induction of the p53-target genes, p21 and GADD45 only occurred in the drug-sensitive CEM cells. Teniposide 162-172 P53 Homo sapiens 31-34 11042688-8 2000 Specifically, while the mutant p53 was phosphorylated at serine-15 in response to ionizing radiation in all these cell lines, mutant p53 induction in response to teniposide or ionizing radiation and induction of the p53-target genes, p21 and GADD45 only occurred in the drug-sensitive CEM cells.

Etoposide 95-104 P53 Homo sapiens 15-18 11070791-6 2000 Transduction of wild-type p53 in LN382 cells also reduced the sensitivity of the cells to etoposide. Etoposide 90-99 P53 Homo sapiens 26-29 11070791-8 2000 These results indicate that cell cycle arrest induced by wild-type p53 function may abrogate the cytotoxic effects of etoposide and paclitaxel, which are dependent on G2M-associated apoptosis. Etoposide 118-127 P53 Homo sapiens 67-70 10913345-0 2000 Activation of the tumor metastasis suppressor gene, KAI1, by etoposide is mediated by p53 and c-Jun genes.

Camptothecin 132-144 P53 Homo sapiens 150-153 10737899-4 2000 We also demonstrate that treatment with p53/56(lyn) antisense oligodeoxynucleotides reverses the 1,25D(3)-induced G1/S block, and results in an accumulation of cells with S-phase DNA content. Oligodeoxyribonucleotides 62-83 P53 Homo sapiens 40-43 10760566-3 2000 Upregulation of endogenous p53 by mitomycin C treatment in MaTu cells also had a profound effect on MN expression as well as the activity of MN promoter in a reporter construct.

Aflatoxin B1 86-92 P53 Homo sapiens 15-18 10767646-6 2000 This indicates that p53 mutation is associated with progression, rather than early development, of HCC in the low-aflatoxin B(1)-exposed region.

Camptothecin 48-60 P53 Homo sapiens 91-94 10749144-7 2000 Interestingly, after camptothecin treatment, increased DNase I sensitivity was detected at the gadd45 promoter, suggesting that an undetermined DNA damage signal is involved in inducing chromatin remodeling at the gadd45 promoter while cooperating with p53 to activate gadd45 transcription.

Genistein 73-82 P53 Homo sapiens 115-118 10761703-5 2000 The inhibitory effects of genistein on cell growth proliferation were associated with a G2/M arrest in cell cycle progression concomitant with a marked inhibition of cyclin B1 and an induction of Cdk inhibitor p21 (WAF1/CIP1) in a p53-independent manner. Genistein 26-35 P53 Homo sapiens 231-234 10462699-9 1999 EGCG also induced the expression of the Cdk inhibitor p21 protein and this effect correlated with the increase in p53 levels. epigallocatechin gallate 0-4 P53 Homo sapiens 114-117 12212278-1 1999 To investigate the expression of P53 protein in the premalignant lesion and carcinoma of laryngeal epithelium, the authors used DO-7, an antibody to wild and mutant type P53 protein. do-7 128-132 P53 Homo sapiens 33-36 10458704-7 1999 To successfully prepare the site-specific adducts, the p53 oligodeoxyribonucleotide was annealed with either the blocking strand d(CTCCATTTTCCT) or d(CCTCCATTTTCCTC) to form the corresponding partial triplexes which targeted AFB(1) adduction either to G(4) or to G(5).

Etoposide 200-209 P53 Homo sapiens 72-75 10644891-7 2000 The representative cell line NCI-H1437 cells transfected with wild-type p53 gene (H1437/wtp53) showed a dramatic increase in susceptibility to three anticancer agents (7-fold to cisplatin, 21-fold to etoposide, and 20-fold to camptothecin) compared to untransfected or neotransfected H1437 cells. Camptothecin 226-238 P53 Homo sapiens 72-75 10974929-1 2000 The purpose of the study was to assess the expression of p53 in non-small cell lung cancer (NSCLC) before and after treatment with cisplatin and vepeside (PE) and to define a relationship between p53 expression and responsiveness to chemotherapy prior to surgery. pe 155-157 P53 Homo sapiens 57-60 10340389-7 1999 From these results, we conclude that genistein inhibits the growth of MDA-MB-231 breast cancer cells, regulates the expression of apoptosis-related genes, and induces apoptosis through a p53-independent pathway. Genistein 37-46 P53 Homo sapiens 187-190 10223459-11 1999 CONCLUSIONS: The present study indicates that clotrimazole inhibits cell proliferation accompanied by morphological changes toward differentiation of glioblastoma cells and that this drug synergistically enhances the antitumor effect of cisplatin by inducing wild-type p53-mediated apoptosis. Clotrimazole 46-58 P53 Homo sapiens 269-272 10349981-8 1999 All of the eight cases of NS showed diffuse positive membrane staining for Ber-EP4 and negative nuclear staining for p53. ns 26-28 P53 Homo sapiens 117-120 16764954-5 2006 While p14(ARF) had no effect on the anchorage-dependent proliferation of p53(-/-) MEFs and Ras12V-transformed p53(-/-) MEFs, it inhibited the growth of Ras12V-transformed p53(-/-) MEFs in soft agar. ras12v 91-97 P53 Homo sapiens 110-113 10096560-5 1999 Treatment of MALME-3M cells with 10 microM N1,N11-diethylnorspermine caused an increase in hypophosphorylated Rb, which correlated temporally with the onset of G1 arrest at 16-24 h. Rb hypophosphorylation was preceded by an increase in wild-type p53 (approximately 100-fold at maximum) and a concomitant increase in the cyclin-dependent kinase inhibitor, p21WAF1/CIP1 (p21; approximately 5-fold at maximum). N(1),N(11)-diethylnorspermine 50-68 P53 Homo sapiens 246-249 10189126-10 1999 Among those patients whose tumors overexpressed p53, there was a trend toward improved outcome in the arm that received 5-FU and mitomycin-C compared with the arm that received 5-FU only. Mitomycin 129-140 P53 Homo sapiens 48-51 10601022-0 1999 Serine15 phosphorylation stimulates p53 transactivation but does not directly influence interaction with HDM2. serine15 0-8 P53 Homo sapiens 36-39 10502297-2 1999 The stable expression of wild-type p53 resulted in a significant increase in sensitivity to the topoisomerase II poisons etoposide and doxorubicin, but not to the topoisomerase II inhibitors razoxane and ADR-529. Etoposide 121-130 P53 Homo sapiens 35-38 16764954-5 2006 While p14(ARF) had no effect on the anchorage-dependent proliferation of p53(-/-) MEFs and Ras12V-transformed p53(-/-) MEFs, it inhibited the growth of Ras12V-transformed p53(-/-) MEFs in soft agar. ras12v 91-97 P53 Homo sapiens 110-113 10518116-9 1999 Retinoic acid increased Bcl-2 and decreased p53 levels, whereas staurosporine decreased Bcl-2 and increased p53 levels. Staurosporine 64-77 P53 Homo sapiens 108-111 10518116-10 1999 The opposite alteration of Bcl-2 (anti-apoptotic) and p53 (apoptotic) contents in SH-SY5Y cells with retinoic acid and staurosporine are attributed to the changes in cell vulnerability. Staurosporine 119-132 P53 Homo sapiens 54-57 10190556-11 1999 Mutations seen similarly in the human Ki-ras codon 12 or p53 codons 157, 248, and 273 of lung tumor were also found in the rpsL gene, and the mutations were suppressed by the EGCG treatment. epigallocatechin gallate 175-179 P53 Homo sapiens 57-60 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 138-147 P53 Homo sapiens 110-113 10355751-0 1999 p53/p21(WAF1/CIP1) expression and its possible role in G1 arrest and apoptosis in ellagic acid treated cancer cells. Ellagic Acid 82-94 P53 Homo sapiens 0-3 10082308-3 1999 METHODS: We report here a parallel flow cytometric method for semiquantitative detection of p53 protein and apoptosis (percent of apoptotic cells) in a pre-B leukemic cell line (NALM-6) exposed to various antitumor agents (2.35 microg/ml etoposide; 0.175 microg/ml FCE296; 0.4 microg/ml FCE624; and 1.5 microg/ml L-PAM). nalm-6 178-184 P53 Homo sapiens 92-95 10082308-3 1999 METHODS: We report here a parallel flow cytometric method for semiquantitative detection of p53 protein and apoptosis (percent of apoptotic cells) in a pre-B leukemic cell line (NALM-6) exposed to various antitumor agents (2.35 microg/ml etoposide; 0.175 microg/ml FCE296; 0.4 microg/ml FCE624; and 1.5 microg/ml L-PAM). Etoposide 238-247 P53 Homo sapiens 92-95 10502735-6 1999 Intratumour density of TAMs was significantly associated with FIGO stage, histological type, histological grade, DNA index, estradiol receptor concentration, intratumour Ki-67 and p53 protein expression (all p < 0.05). tams 23-27 P53 Homo sapiens 180-183 10523305-8 1999 Finally, we observed that Ref-1 cooperates with a DNA-damaging compound, camptothecin, to stimulate the transcriptional activity of p53. Camptothecin 73-85 P53 Homo sapiens 132-135 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 138-147 P53 Homo sapiens 173-176 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 138-147 P53 Homo sapiens 173-176 10521394-4 1999 We report that trichostatin A (TSA), an inhibitor of histone deacetylases (HDACs), abrogates the ability of p53 to repress the transcription of two genes that it negatively regulates, Map4 and stathmin. trichostatin A 15-29 P53 Homo sapiens 108-111 10521394-4 1999 We report that trichostatin A (TSA), an inhibitor of histone deacetylases (HDACs), abrogates the ability of p53 to repress the transcription of two genes that it negatively regulates, Map4 and stathmin. trichostatin A 31-34 P53 Homo sapiens 108-111 10448308-0 1999 Ginsenoside-Rs4, a new type of ginseng saponin concurrently induces apoptosis and selectively elevates protein levels of p53 and p21WAF1 in human hepatoma SK-HEP-1 cells. ginsenoside-rs4 0-15 P53 Homo sapiens 121-124 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 138-147 P53 Homo sapiens 173-176 10448308-1 1999 In this paper, we present evidence that ginsenoside-Rs4 (G-Rs4; an acetylated analogue of ginsenoside-Rg5), a new ginseng saponin isolated from Panax ginseng C. A. Meyer, elevates protein levels of p53 and p21WAF1, which are associated with the induction of apoptosis in SK-HEP-1 cells. ginsenoside-rs4 40-55 P53 Homo sapiens 198-201 10448308-5 1999 We suggest that G-Rs4 induces apoptosis, the effect of which is closely related to the downregulation of both cyclins E- and A-dependent kinase activity as a consequence of selectively elevating protein levels of p53 and p21WAF1 in SK-HEP-1 cells. g-rs4 16-21 P53 Homo sapiens 213-216 12712688-1 1999 The alteration of p53 and K-ras gene in 36 lung cancers of workers occupationally exposed to silica (LCWS) was studied. Silicon Dioxide 93-99 P53 Homo sapiens 18-21 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 149-151 P53 Homo sapiens 110-113 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 149-151 P53 Homo sapiens 173-176 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 149-151 P53 Homo sapiens 173-176 16847267-4 2006 Here we present evidence indicating that MageA2 protein, belonging to the MAGE-A subfamily, confers wild-type-p53-sensitive resistance to etoposide (ET) by inducing a novel p53 inhibitory loop involving recruitment of histone deacetylase 3 (HDAC3) to MageA2/p53 complex, thus strongly down-regulating p53 transactivation function. Etoposide 149-151 P53 Homo sapiens 173-176 10051487-1 1999 A particular point mutation of the tumor suppressor gene p53, namely a G-->T transversion at the third base of codon 249, is frequently detected in primary hepatocellular carcinomas from patients living in areas where the levels of dietary exposure to aflatoxin B1 and the rates of infection with the hepatitis B virus are very high. Aflatoxin B1 255-267 P53 Homo sapiens 57-60 10051487-5 1999 Thus, these results strongly support the view that the mutation at codon 249 of the p53 gene may serve as a fingerprint for aflatoxin B1-induced hepatocellular carcinomas, but is not, by itself, sufficient to immortalize human liver cells. Aflatoxin B1 124-136 P53 Homo sapiens 84-87 10505853-7 1999 Analysis of cell cycle and apoptosis in etoposide-treated cells corroborated the inability of NP-29 to die by apoptosis, suggesting that this wt p53 cell line lacks p53 downstream functions in the apoptosis pathway. Etoposide 40-49 P53 Homo sapiens 145-148 16847267-7 2006 In addition, combined trichostatin A/ET treatment in melanoma cells expressing high MAGE-A levels reestablishes p53 response and reverts the chemoresistance. trichostatin A 22-36 P53 Homo sapiens 112-115 10427135-3 1999 We have previously shown that genistein inhibits the growth of MDA-MB-231 breast cancer cells, regulates the expression of apoptosis-related genes, and induces apoptosis through a p53-independent pathway. Genistein 30-39 P53 Homo sapiens 180-183 16847267-7 2006 In addition, combined trichostatin A/ET treatment in melanoma cells expressing high MAGE-A levels reestablishes p53 response and reverts the chemoresistance. Etoposide 37-39 P53 Homo sapiens 112-115 10094469-5 1999 Furthermore, endogenous S100A2 mRNA expression is induced by etoposide in p53 positive, but not in p53 negative cells. Etoposide 61-70 P53 Homo sapiens 74-77 16818668-0 2006 p53 expression after treatment with zebularine is not due to demethylation. pyrimidin-2-one beta-ribofuranoside 36-46 P53 Homo sapiens 0-3 10094470-1 1999 DNA chip technology was used in an attempt to identify target genes responsible for apoptosis induced by etoposide, a p53 activating topoisomerase II inhibitor used clinically as an antitumor agent. Etoposide 105-114 P53 Homo sapiens 118-121 10455888-11 1999 CONCLUSIONS: Treatment with CPT effectively inhibited the growth of the human gastric cancer SIIA; the mechanism involved was induction of apoptosis mediated by up-regulation of p53, p21Waf1/Cip1, and p27Kip1 and the down-regulation of Bcl-2 and Bcl-XL. Camptothecin 28-31 P53 Homo sapiens 178-181 16547931-0 2006 The course of etoposide-induced apoptosis in Jurkat cells lacking p53 and Bax. Etoposide 14-23 P53 Homo sapiens 66-69 10517975-8 1999 For example, exposure to ultraviolet light is correlated with transition mutations at dipyrimidine sites; aflatoxin B(1) exposure is correlated with a G:C to T:A transversion that leads to a serine substitution at residue 249 of p53 in hepatocellular carcinoma; and exposure to cigarette smoke is correlated with G:C to T:A transversions in lung carcinoma. Aflatoxin B1 106-117 P53 Homo sapiens 229-232 9950253-1 1999 Expression of p53 protein was examined in oral squamous cell carcinoma (SCC) from patients who were areca quid (AQ) chewers and/or tobacco smokers, using anti-p53 antibodies with an immunoperoxidase technique. aq 112-114 P53 Homo sapiens 14-17 9950253-3 1999 p53 overexpression was found to be higher in patients without AQ chewing and smoking habits than in patients with these two habits (80% vs 52%, P=0.076). aq 62-64 P53 Homo sapiens 0-3 10391558-9 1999 p53 mutations were found in 4 of 16 GCCs (25%) and 8 of 18 TCs (44%). 9-ethyl-N-(3,4,5-trimethoxyphenyl)carbazole-3-sulfonamide 59-62 P53 Homo sapiens 0-3 16778203-8 2006 Furthermore, we provided evidence that inhibition of protein methyltransferases, especially arginine methyltransferases, relieve the repression of ECT2 induced by DNA damage or Nutlin-3 in a p53-dependent manner. nutlin 3 177-185 P53 Homo sapiens 191-194 10391558-11 1999 CONCLUSIONS: p53 mutations appear to play a role in the pathogenesis of some GCCs and in approximately 50% of TCs of the appendix, whereas mutations in the K-ras oncogene do not appear to be important in the development of these tumors. 9-ethyl-N-(3,4,5-trimethoxyphenyl)carbazole-3-sulfonamide 110-113 P53 Homo sapiens 13-16 10381922-2 1999 Aflatoxin B1 causes a specific point mutation in the p53 tumor-suppressor gene in exposed individuals. Aflatoxin B1 0-12 P53 Homo sapiens 53-56 10023685-0 1999 Differential regulation of p21waf-1/cip-1 and Mdm2 by etoposide: etoposide inhibits the p53-Mdm2 autoregulatory feedback loop. Etoposide 54-63 P53 Homo sapiens 88-91 10023685-0 1999 Differential regulation of p21waf-1/cip-1 and Mdm2 by etoposide: etoposide inhibits the p53-Mdm2 autoregulatory feedback loop. Etoposide 65-74 P53 Homo sapiens 88-91 10023685-9 1999 When cells are -treated with a pulse (1 h) of etoposide and reincubated in drug free medium, Mdm2 synthesis commences immediately after damage is repaired (3 h) and the p53 response is attenuated. Etoposide 46-55 P53 Homo sapiens 169-172 9927204-6 1999 Moreover, p53His175 as well as p53His179 reduced substantially the rate of etoposide-induced apoptosis, whereas p53His273 and p53Trp248 had a much milder protective effect. Etoposide 75-84 P53 Homo sapiens 31-34 10383145-5 1999 Either phosphatidylinositol (PI) 3-kinase or mitogen-activated protein kinase kinase (MEK) antagonized p53-induced apoptosis, and an additive preventive effect was observed when both kinases were activated. Phosphatidylinositols 7-27 P53 Homo sapiens 103-106 16799873-11 2006 Cyclin A1 but not cyclin A2 was upregulated in etoposide-treated tumor cells undergoing p53-dependent apoptosis and mitotic catastrophe. Etoposide 47-56 P53 Homo sapiens 88-91 14634277-6 1999 We conclude that high concentrations of L-745,337 and sodium salicylate inhibit colon cancer cell growth by a mechanism unrelated to cyclooxygenase inhibition that may involve p53-independent induction of the tumor suppressor p21WAF-1/cip1. Sodium Salicylate 54-71 P53 Homo sapiens 176-179 10634308-0 1999 Effect of p53 tumor suppressor on nucleotide excision repair in human colon carcinoma cells treated with 4-nitroquinoline 1-oxide. 4-Nitroquinoline-1-oxide 105-129 P53 Homo sapiens 10-13 10634308-1 1999 In probing the mechanism of nucleotide excision repair (NER) in response to 4-nitroquinoline 1-oxide (4NQO)-induced DNA damage, the effect of p53 tumor suppressor was investigated. 4-Nitroquinoline-1-oxide 76-100 P53 Homo sapiens 142-145 10634308-4 1999 Compared to RKO cells having the wild-type p53 gene, increased cytotoxicity by 4NQO was observed in RKOmp53 cells with a mutation in p53 protein. 4-Nitroquinoline-1-oxide 79-83 P53 Homo sapiens 43-46 10634308-4 1999 Compared to RKO cells having the wild-type p53 gene, increased cytotoxicity by 4NQO was observed in RKOmp53 cells with a mutation in p53 protein. 4-Nitroquinoline-1-oxide 79-83 P53 Homo sapiens 104-107 10634308-6 1999 Also, the expression of p53 and p21 proteins was significantly increased in 4NQO-treated RKO cells. 4-Nitroquinoline-1-oxide 76-80 P53 Homo sapiens 24-27 10634308-8 1999 Our findings suggest that 4NQO-induced NER is p53-dependent and involves up-regulation of its downstream regulator, p21(Waf1/Cip1) proteins. 4-Nitroquinoline-1-oxide 26-30 P53 Homo sapiens 46-49 10207030-4 1999 This site bound to purified p53 as well as p53 in nuclear extract activated by etoposide. Etoposide 79-88 P53 Homo sapiens 28-31 10207030-4 1999 This site bound to purified p53 as well as p53 in nuclear extract activated by etoposide. Etoposide 79-88 P53 Homo sapiens 43-46 10207030-7 1999 The p53 binding and transactivation of the GPX promoter were enhanced by etoposide in p53-positive U2-OS cells. Etoposide 73-82 P53 Homo sapiens 4-7 16684540-4 2006 PAF-induced increase in VEGF expression was correlated with decreased p53 activity. Platelet Activating Factor 0-3 P53 Homo sapiens 70-73 10207030-7 1999 The p53 binding and transactivation of the GPX promoter were enhanced by etoposide in p53-positive U2-OS cells. Etoposide 73-82 P53 Homo sapiens 86-89 10207030-8 1999 Etoposide-induced transactivation was blocked by a dominant negative p53 mutant, indicating that endogenous wild type p53, upon activation by etoposide, transactivated the GPX promoter. Etoposide 0-9 P53 Homo sapiens 69-72 10327058-2 1999 We employ a tet-repressible system to show that, under conditions in which the WAF1 mRNA steady-state level is upregulated fourfold by p53, the SCL mRNA level is not altered. tetramethylenedisulfotetramine 12-15 P53 Homo sapiens 135-138 10327058-3 1999 In a previous report, we demonstrated that p53 interactions with the SCL CS can upregulate downstream reporter gene activity 43-fold in transient reporter assays. Cesium 73-75 P53 Homo sapiens 43-46 10327058-4 1999 This disparity prompted us to explore the differences between p53 regulation of SCL CS activity in organized (chromosomally integrated) and disorganized (non-replicating episomal plasmid) chromatin. Cesium 84-86 P53 Homo sapiens 62-65 10022257-8 1998 For example, characteristic p53 mutation spectra have been associated with: dietary aflatoxin B1 exposure and hepatocellular carcinoma; sunlight exposure and skin carcinoma; and cigarette smoking and lung cancer.

CP 31398 122-130 P53 Homo sapiens 95-98 9506540-3 1998 When p53 was expressed at sublethal levels, it sensitized cells to the DNA-damaging drugs Adriamycin, mitomycin C, actinomycin D, etoposide (VP16), cisplatin and CPT11. Etoposide 141-145 P53 Homo sapiens 5-8 16225598-12 2005 More studies are necessary, to further investigate the effect of CP-31398 on mutant p53 and its potential applications as an anticancer agent. CP 31398 65-73 P53 Homo sapiens 84-87 16186332-8 2005 Treatment with mitomycin-C resulted in the increased expression of Fas, FasL, Bad, and phosphorylated p53 and a decreased level of phosphorylated AKT. Mitomycin 15-26 P53 Homo sapiens 102-105 9482877-4 1998 Phorbol ester, a potent activator of PKC, significantly inhibited the accumulation of p53 after DNA damage. Phorbol Esters 0-13 P53 Homo sapiens 86-89 16202244-3 2005 Here we showed that etoposide can induce the similar degree of cell death in p53-deficient HCT 116 cells, whereas 5"-FU-mediated cell death is strongly dependent on the existence of functional p53 in HCT 116 cells. Etoposide 20-29 P53 Homo sapiens 77-80 9568504-1 1998 AIMS: Recent reports suggest that genetic examination of K-ras or p53 mutation is more sensitive for the detection of occult lymph node metastasis in colorectal carcinomas than conventional examination by haematoxylin and eosin (H & E) staining or immunohistochemistry for gene products. Eosine Yellowish-(YS) 222-227 P53 Homo sapiens 66-69 9464250-2 1998 We used doxorubicin (DOX) and sodium butyrate (NaB) to accumulate p53 protein. nab 47-50 P53 Homo sapiens 66-69 16202244-5 2005 These data suggest that etoposide can directly induce the mitochondrial dysfunction irrespective of p53 status, and it may, at least in part, account for the p53-independent pathway in cell death induced by chemotherapeutic agents. Etoposide 24-33 P53 Homo sapiens 158-161 16177181-5 2005 TSA-induced toxicity stimulates apoptosis and cell cycle checkpoint responses independent of p53, but does not increase phosphorylated histone H2AX (-H2AX) as compared with a clastogenic agent, camptothecin, indicating that the quantity of DSBs is not the primary cause of TSA-induced cell death. trichostatin A 0-3 P53 Homo sapiens 93-96 9543255-5 1998 Teniposide enhanced CD95 expression in a glioma cell line with wild-type p53 (LN-229) but not in two p53 mutant cell lines (T98G, LN-308). Teniposide 0-10 P53 Homo sapiens 73-76 9543255-6 1998 Forced expression of a transdominant negative p53 mutant prevented the teniposide induced augmentation of CD95 expression in LN-229 cells but did not prevent the synergy of CD95 ligand and teniposide. Teniposide 71-81 P53 Homo sapiens 46-49 16121349-7 2005 The 249serine p53 gene mutation was detected in 27.2% of the hepatocellular carcinoma tissues but not in non-cancerous tissues. 249serine 4-13 P53 Homo sapiens 14-17 9773296-6 1998 The technique of microwave antigen retrieval gave crisp, clear immunohistochemical staining for p53 in tissues fixed in neutral buffered formalin or Bouin solution. bouin 149-154 P53 Homo sapiens 96-99 15940259-8 2005 Interestingly, in p53 knockdown cells nearly the entire set of identified cisplatin targets fail to respond or have a diminished response to cisplatin, suggesting that many are new direct or indirect targets of p53 including GPR87, STK17A, INPP5D, FLJ11259, and EPS8L2. flj11259 248-256 P53 Homo sapiens 18-21 10921048-11 1998 The close association of the hotspot mutation of p53 gene in Qidong HCC with the presence of HBVx gene sequence suggests that such mutation is the molecular footprint of the combined effect of aflatoxin B1 exposure and HBVx gene product. Aflatoxin B1 193-205 P53 Homo sapiens 49-52 15940259-8 2005 Interestingly, in p53 knockdown cells nearly the entire set of identified cisplatin targets fail to respond or have a diminished response to cisplatin, suggesting that many are new direct or indirect targets of p53 including GPR87, STK17A, INPP5D, FLJ11259, and EPS8L2. flj11259 248-256 P53 Homo sapiens 211-214 16093994-0 2005 Differential regulation of p21waf-1/cip-1 and Mdm2 by etoposide: etoposide inhibits the p53-Mdm2 autoregulatory feedback loop. Etoposide 65-74 P53 Homo sapiens 88-91 9570360-2 1997 The most frequent p53 mutation has been found in HCCs in regions with high hepatitis B virus (HBV) infection and intake of aflatoxin B1 (AFB1). Aflatoxin B1 123-135 P53 Homo sapiens 18-21 16103091-2 2005 We show that histone deacetylase inhibitors such as FR901228 and trichostatin A completely depleted mutant p53 in cancer cell lines. romidepsin 52-60 P53 Homo sapiens 107-110 9405248-7 1997 These findings indicate that TSA induces the WAF1/Cip1 promoter through the typical Sp1 sites, in a p53-independent fashion. trichostatin A 29-32 P53 Homo sapiens 100-103 16103091-2 2005 We show that histone deacetylase inhibitors such as FR901228 and trichostatin A completely depleted mutant p53 in cancer cell lines. trichostatin A 65-79 P53 Homo sapiens 107-110 9434882-0 1997 Induction of p53 protein expression by sodium arsenite. sodium arsenite 39-54 P53 Homo sapiens 13-16 15914462-8 2005 Treatment of colon and ovarian carcinoma cells with the anticancer genotoxic agent etoposide up-regulated both p53 and proline oxidase, activated calcineurin, and induced apoptosis. Etoposide 83-92 P53 Homo sapiens 111-114 9434882-3 1997 Intrigued by these effects and based on the role of p53 on cell proliferation, we tested different concentrations of sodium arsenite for their ability to induce the expression of tumor suppressor gene p53 in different cell lines (HeLa, C-33A. sodium arsenite 117-132 P53 Homo sapiens 52-55 9434882-3 1997 Intrigued by these effects and based on the role of p53 on cell proliferation, we tested different concentrations of sodium arsenite for their ability to induce the expression of tumor suppressor gene p53 in different cell lines (HeLa, C-33A. sodium arsenite 117-132 P53 Homo sapiens 201-204 15908423-4 2005 Nuclear accumulation of p53 protein in mdm2 SNP309 cells results after 6 h of camptothecin, etoposide, or mitomycin C treatment, with the p53 protein phosphorylated at Ser15. Camptothecin 78-90 P53 Homo sapiens 24-27 9434882-6 1997 Immunoblots showed an increased expression of p53 gene with 1 microM sodium arsenite in Jurkat cells and 10 microM sodium arsenite in HeLa and LCL-EBV cells. sodium arsenite 69-84 P53 Homo sapiens 46-49 9434882-6 1997 Immunoblots showed an increased expression of p53 gene with 1 microM sodium arsenite in Jurkat cells and 10 microM sodium arsenite in HeLa and LCL-EBV cells. sodium arsenite 115-130 P53 Homo sapiens 46-49 15908423-4 2005 Nuclear accumulation of p53 protein in mdm2 SNP309 cells results after 6 h of camptothecin, etoposide, or mitomycin C treatment, with the p53 protein phosphorylated at Ser15. Etoposide 92-101 P53 Homo sapiens 24-27 9494534-8 1997 Levels of p53 mRNA decreased with increasing resistance to vindesine, etoposide and fotemustine. Vindesine 59-68 P53 Homo sapiens 10-13 15908423-4 2005 Nuclear accumulation of p53 protein in mdm2 SNP309 cells results after 6 h of camptothecin, etoposide, or mitomycin C treatment, with the p53 protein phosphorylated at Ser15. Mitomycin 106-117 P53 Homo sapiens 24-27 15832344-0 2005 JNK/p53 mediated cell death response in K562 exposed to etoposide-ionizing radiation combined treatment. Etoposide 56-65 P53 Homo sapiens 4-7 9343394-6 1997 Treatment of U2-OS cells, a wild-type p53-containing osteogenic sarcoma line, with a common p53 inducer, etoposide, induced p53 DNA binding and transactivation activities in a time-dependent manner. Etoposide 105-114 P53 Homo sapiens 38-41 11819223-1 1998 AIM:To study the p53 gene mutation and its relationship to aflatoxin B1 exposure in hepatocellular carcinoma (HCC).METHODS: Restriction fragment length polymorphism analysis method was used in 62 HCC samples, and DNA direct sequencing in another 45 HCC samples.RESULTS: In HCC and AFB1 high and low-risk areas, 36/52 (69%) and 2/10 (20%) cases were found losing the HaeIII allele respectively, suggesting one of the base G mutation at the p53 gene codon 249. Aflatoxin B1 59-71 P53 Homo sapiens 17-20 9343394-6 1997 Treatment of U2-OS cells, a wild-type p53-containing osteogenic sarcoma line, with a common p53 inducer, etoposide, induced p53 DNA binding and transactivation activities in a time-dependent manner. Etoposide 105-114 P53 Homo sapiens 92-95 15832344-5 2005 Moreover, p53 is a potential substrate for JNK and may act as a JNK target for etoposide and ionizing radiation. Etoposide 79-88 P53 Homo sapiens 10-13 9343394-6 1997 Treatment of U2-OS cells, a wild-type p53-containing osteogenic sarcoma line, with a common p53 inducer, etoposide, induced p53 DNA binding and transactivation activities in a time-dependent manner. Etoposide 105-114 P53 Homo sapiens 92-95 15833870-13 2005 Finally, induction of p21 by phenoxodiol is p53 independent, as phenoxodiol induced p21 in HCT116 lacking p53. phenoxodiol 29-40 P53 Homo sapiens 44-47 9484835-12 1998 Of the tested inhibitors, only staurosporine, a known inhibitor of protein kinase C (PKC) and various other kinases, inhibited both p53 activation and accumulation, whereas specific PKC inhibitors, tyrosine kinase inhibitors and a serine/threonine kinase inhibitor did not. Staurosporine 31-44 P53 Homo sapiens 132-135 9484835-14 1998 Kinetic studies showed that staurosporine-mediated inhibition of p53 function is an early event in cell damage response. Staurosporine 28-41 P53 Homo sapiens 65-68 9484835-15 1998 Thus dual, kinetically different events, de novo protein synthesis and staurosporine-inhibited protein phosphorylation are required for p53 activation and accumulation in all phases of the cell cycle. Staurosporine 71-84 P53 Homo sapiens 136-139 15833870-14 2005 These data therefore indicate that phenoxodiol promotes G(1)-S arrest by the specific loss in cdk2 activity due to p53-independent p21(WAF1) induction. phenoxodiol 35-46 P53 Homo sapiens 115-118 9307289-0 1997 Abrogation of an S-phase checkpoint and potentiation of camptothecin cytotoxicity by 7-hydroxystaurosporine (UCN-01) in human cancer cell lines, possibly influenced by p53 function. Camptothecin 56-68 P53 Homo sapiens 168-171 15805279-3 2005 We previously showed that infection by human cytomegalovirus (HCMV) induced drug resistance and altered p53- and p73-dependent apoptosis of infected cells through accumulation of DeltaN-p73alpha. deltan-p73alpha 179-194 P53 Homo sapiens 104-107 9307289-2 1997 In this study, we found that nanomolar concentrations of camptothecin (CPT), a topoisomerase I inhibitor, arrest or delay cell cycle progression during the S and G2 phases in p53 mutant human colon carcinoma HT29 cells and that UCN-01 abrogates the S-phase arrest or delay induced by CPT. Camptothecin 57-69 P53 Homo sapiens 175-178 9307289-2 1997 In this study, we found that nanomolar concentrations of camptothecin (CPT), a topoisomerase I inhibitor, arrest or delay cell cycle progression during the S and G2 phases in p53 mutant human colon carcinoma HT29 cells and that UCN-01 abrogates the S-phase arrest or delay induced by CPT. Camptothecin 71-74 P53 Homo sapiens 175-178 10026991-8 1998 For example, characteristic p53 mutation spectra have been associated with: dietary aflatoxin B1 exposure and hepatocellular carcinoma; sunlight exposure and skin carcinoma; and cigarette smoking and lung cancer. Aflatoxin B1 84-96 P53 Homo sapiens 28-31 15814660-0 2005 Tirapazamine cytotoxicity for neuroblastoma is p53 dependent. Tirapazamine 0-12 P53 Homo sapiens 47-50 9815856-0 1997 Inactivation of p53 increases the cytotoxicity of camptothecin in human colon HCT116 and breast MCF-7 cancer cells. Camptothecin 50-62 P53 Homo sapiens 16-19 15814660-5 2005 TPZ exhibited high cytotoxicity, especially in hypoxia (2% O2), for all four p53-functional neuroblastoma cell lines, achieving >3 logs of cell kill (LC99 < or = 0.7 microg/mL). Tirapazamine 0-3 P53 Homo sapiens 77-80 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. epigallocatechin gallate 11-38 P53 Homo sapiens 123-126 9285694-5 1997 Comparatively, a treatment of the cells with 100 nM 4OH-tamoxifen (OHT) decreased cell number to 40% of the control without a concomitant decrease in the p53 levels suggesting a differential ability of these antiestrogens to regulate p53 levels in cells cultured in whole serum. 4oh-tamoxifen 52-65 P53 Homo sapiens 154-157 9285694-5 1997 Comparatively, a treatment of the cells with 100 nM 4OH-tamoxifen (OHT) decreased cell number to 40% of the control without a concomitant decrease in the p53 levels suggesting a differential ability of these antiestrogens to regulate p53 levels in cells cultured in whole serum. 4oh-tamoxifen 52-65 P53 Homo sapiens 234-237 9437796-14 1997 Our studies show that exposure to phenolphthalein combined with a genetic predisposition to cancer can potentiate the carcinogenic process and cause p53 gene alterations, a gene alteration found in many human cancers. Phenolphthalein 34-49 P53 Homo sapiens 149-152 9315628-0 1997 Regulation of p53 by metal ions and by antioxidants: dithiocarbamate down-regulates p53 DNA-binding activity by increasing the intracellular level of copper. Dithiocarbamate 53-68 P53 Homo sapiens 14-17 9315628-0 1997 Regulation of p53 by metal ions and by antioxidants: dithiocarbamate down-regulates p53 DNA-binding activity by increasing the intracellular level of copper. Dithiocarbamate 53-68 P53 Homo sapiens 84-87 9315628-3 1997 To address this question, we have analyzed the effect of pyrrolidine dithiocarbamate (PDTC) on p53 DNA-binding activity in cell lines expressing wild-type p53. pyrrolidine dithiocarbamic acid 57-84 P53 Homo sapiens 95-98 9315628-3 1997 To address this question, we have analyzed the effect of pyrrolidine dithiocarbamate (PDTC) on p53 DNA-binding activity in cell lines expressing wild-type p53. pyrrolidine dithiocarbamic acid 86-90 P53 Homo sapiens 95-98 9285062-7 1997 The results show that MMC treatment inhibited sod1 gene transcription through p53-mediated transcriptional repression. Mitomycin 22-25 P53 Homo sapiens 78-81 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. epigallocatechin gallate 11-38 P53 Homo sapiens 254-257 9212217-5 1997 The p53 mutational spectrum was 50% transitions (3 C-to-T and 1 G-to-A, all occurring at CpG dinucleotide sites) and 50% transversions (one each, C-to-G, G-to-T, T-to-G, and T-to-A). Dinucleoside Phosphates 93-105 P53 Homo sapiens 4-7 9212237-8 1997 Treatment of both cell lines with mitomycin C (MMC), which acts with a mechanism different from CDDP, caused equal accumulation of p53 and induction of bax. Mitomycin 34-45 P53 Homo sapiens 131-134 9212237-8 1997 Treatment of both cell lines with mitomycin C (MMC), which acts with a mechanism different from CDDP, caused equal accumulation of p53 and induction of bax. Mitomycin 47-50 P53 Homo sapiens 131-134 15772596-8 2005 However, the staining rate of p53 in OLP was higher in areca quid (AQ) chewers compared to abstainers (P = .001), and the mean PCNA LI in atrophic cases was higher than that in hypertrophic cases (P = .029). aq 67-69 P53 Homo sapiens 30-33 9812593-0 1997 [A preliminary study on p53 gene in lung cancer tissues of workers exposed to silica and welding fumes]. Silicon Dioxide 78-84 P53 Homo sapiens 24-27 9812593-1 1997 Mutations of suppressor gene p53 was studied in 36 cases of silica related lung cancer and 6 cases of welding fume related lung cancer with immunohistochemical and PCR-SSCP methods.

Verapamil 46-55 P53 Homo sapiens 124-127 9354939-9 1997 Also, apoptosis of HT-29 cells produced by hyperthermia in the presence of verapamil is a p53-independent process. Verapamil 75-84 P53 Homo sapiens 90-93 9006107-0 1996 Absence of mutations in the p53 tumor suppressor gene in woodchuck hepatocellular carcinomas associated with hepadnavirus infection and intake of aflatoxin B1. Aflatoxin B1 146-158 P53 Homo sapiens 28-31 15772596-9 2005 Interestingly, the staining rate of p53 and mean PCNA LI were significantly increased in AQ chewers with atrophic OLP (100%, 36.7% +/- 9.0%, respectively), which were similar to those in ED and SCC (all P > .05). aq 89-91 P53 Homo sapiens 36-39 8945622-4 1996 When exposed to DNA-damaging agents, cisplatin or mitomycin C, apoptosis was induced in RT4 with the wild-type (wt) p53/wt p21, whereas T24 with the p53 non-sense mutation/wt p21 was resistant. Mitomycin 50-61 P53 Homo sapiens 116-119 15755327-0 2005 Activation of p53, inhibition of telomerase activity and induction of estrogen receptor beta are associated with the anti-growth effects of combination of ovarian hormones and retinoids in immortalized human mammary epithelial cells. ovarian hormones 155-171 P53 Homo sapiens 14-17 8945622-4 1996 When exposed to DNA-damaging agents, cisplatin or mitomycin C, apoptosis was induced in RT4 with the wild-type (wt) p53/wt p21, whereas T24 with the p53 non-sense mutation/wt p21 was resistant. Mitomycin 50-61 P53 Homo sapiens 149-152 8950211-4 1996 DDB (10(-4) M) could significantly increase the content of cAMP in Bel-7402 cells, and also enhance the expression of anti-oncogene p53. ddb 0-3 P53 Homo sapiens 132-135 9816112-7 1996 We also find that induction of wild-type p53 potentiates the cytotoxicity of topotecan, a member of the camptothecin family of drugs that also has clinical activity against colon cancer. Camptothecin 104-116 P53 Homo sapiens 41-44 9269997-2 1997 Similarly, upon treatment with S-nitroso-N-acetyl-DL-penicillamine (2-5 mM) or S-nitroso-glutathione (1-2 mM), human breast cancer cells (MCF-7), which express wild-type p53, rapidly accumulated p53 protein in the nuclei. snap 31-66 P53 Homo sapiens 170-173 9269997-2 1997 Similarly, upon treatment with S-nitroso-N-acetyl-DL-penicillamine (2-5 mM) or S-nitroso-glutathione (1-2 mM), human breast cancer cells (MCF-7), which express wild-type p53, rapidly accumulated p53 protein in the nuclei. snap 31-66 P53 Homo sapiens 195-198 9263993-13 1997 In contrast, cytokines in combination with pyrrolidine dithiocarbamate, which blocks endogenous superoxide dismutase, allowed p53 and Bax accumulation as well as DNA fragmentation. pyrrolidine dithiocarbamic acid 43-70 P53 Homo sapiens 126-129 15701509-1 2005 It is well known that CpG dinucleotide steps in DNA, which are highly methylated at the 5-position of cytosine (meC) in human tissues, exhibit a disproportionate number of mutations within certain codons of the p53 gene. Dinucleoside Phosphates 26-38 P53 Homo sapiens 211-214 9230270-1 1997 Epidemiological evidence has been supporting a relationship between dietary aflatoxin B1 (AFB1) exposure, development of human primary hepatocellular carcinoma (HCC) and mutations in the p53 tumor suppressor gene. Aflatoxin B1 76-88 P53 Homo sapiens 187-190 9230270-1 1997 Epidemiological evidence has been supporting a relationship between dietary aflatoxin B1 (AFB1) exposure, development of human primary hepatocellular carcinoma (HCC) and mutations in the p53 tumor suppressor gene. Aflatoxin B1 90-94 P53 Homo sapiens 187-190 9408079-0 1997 The mammalian metabolite, 2-methoxyestradiol, affects P53 levels and apoptosis induction in transformed cells but not in normal cells. 2-Methoxyestradiol 26-44 P53 Homo sapiens 54-57 8886839-7 1996 In vitro studies showed that cell growth, as measured by the thymidine incorporation assay, was inhibited in the C4-2, PC-3, and DU145 cells infected with wild-type p53 adenovirus in comparison to control viruses. Thymidine 61-70 P53 Homo sapiens 165-168 21541495-1 1996 Gel fiberglass (GFG), a new affinity biosensor, was used to isolate human p53 antigen with rabbit anti-rat p53 IgG. guanfu base G 16-19 P53 Homo sapiens 74-77 15557088-7 2005 TUNEL and DNA fragmentation analysis show that silica caused apoptosis in both JB6 cells and wild-type p53 (p53+/+) fibroblasts but not in p53-deficient (p53-/-) fibroblasts. Silicon Dioxide 47-53 P53 Homo sapiens 108-111 21541495-1 1996 Gel fiberglass (GFG), a new affinity biosensor, was used to isolate human p53 antigen with rabbit anti-rat p53 IgG. guanfu base G 16-19 P53 Homo sapiens 107-110 21541495-13 1996 Herein, we report for the first time the capability to isolate human p53 antigen using GFG columns with entrapped anti-rat p53 IgG. guanfu base G 87-90 P53 Homo sapiens 69-72 8673929-4 1996 In vitro investigations have shown intact p53 to play a critical role executing cell death in response to treatment with cytotoxic drugs like 5-fluorouracil, etoposide and doxorubicin. Etoposide 158-167 P53 Homo sapiens 42-45 9219564-3 1997 We found that exposure of human lung adenocarcinoma A549 cells to sodium arsenite (0.08-2 microM) or sodium arsenate (30-300 microM), but not dimethylarsenic acid (2-2000 microM), produced significant dose-responsive hypermethylation within a 341-base pair fragment of the promoter of p53. sodium arsenite 66-81 P53 Homo sapiens 285-288 15868936-6 2005 Ellagic acid also increased p53 and p21 and decreased CDK2 gene expression, that may lead to the G0/G1 arrest of T24 cells.

Thymidine 66-75 P53 Homo sapiens 13-16 7737156-6 1995 However, when we employed the phosphatase inhibitor okadaic acid, overall phosphorylation of p53 was drastically enhanced in a dose-dependent manner and resembled that of p53 from SV40-transformed rat cells. Okadaic Acid 52-64 P53 Homo sapiens 93-96 7737156-6 1995 However, when we employed the phosphatase inhibitor okadaic acid, overall phosphorylation of p53 was drastically enhanced in a dose-dependent manner and resembled that of p53 from SV40-transformed rat cells. Okadaic Acid 52-64 P53 Homo sapiens 171-174 7705850-0 1995 Polymorphism of the pentanucleotide repeat d(AAAAT) within intron 1 of the human tumor suppressor gene p53 (17p13.1). pentanucleotide 20-35 P53 Homo sapiens 103-106 15308639-6 2004 Here we show that mutant p53, isolated from cells treated with CP-31398, is capable of binding to p53 response elements in vitro. CP 31398 63-71 P53 Homo sapiens 25-28 7892276-1 1995 Aflatoxin B1 (AFB1) has been postulated to be a hepatocarcinogen in humans, possibly by causing p53 mutations at codon 249. Aflatoxin B1 0-12 P53 Homo sapiens 96-99 15308639-6 2004 Here we show that mutant p53, isolated from cells treated with CP-31398, is capable of binding to p53 response elements in vitro. CP 31398 63-71 P53 Homo sapiens 98-101 15308639-8 2004 In addition, using purified p53 core domain from two different hotspot mutants (R273H and R249S), we show that CP-31398 can restore DNA-binding activity in a dose-dependent manner. CP 31398 111-119 P53 Homo sapiens 28-31 7889486-6 1995 Intranuclear accumulation of p53 protein was immunostained with the avidin-biotin complex method. avidin-biotin 68-81 P53 Homo sapiens 29-32 15492260-4 2004 In two melanomas with wild-type p53 but with differential expression of APAF-1, treatment with camptothecin, celecoxib, or an nitric oxide synthase inhibitor (1400W) significantly modulated expression of 36 of 96 genes in an apoptosis-specific cDNA macroarray, but APAF-1 mRNA levels were not induced (in APAF-1(-) cells) nor up-regulated (in APAF-1(+) cells), a finding confirmed at the protein level. Camptothecin 95-107 P53 Homo sapiens 32-35 7923176-11 1994 p53 allelic amino acid variation with sequences coding for aspartic acid or asparagine was present in codon 61 in the variable region of exon 4 in both HCCs and nonneoplastic tissues of ground squirrels. Asparagine 76-86 P53 Homo sapiens 0-3 7931472-2 1994 MATERIALS AND METHODS: Paraffin sections from the primary tumors in 107 colorectal cancer patients who had preoperative serum carcinoembryonic antigen (CEA) levels less than five were examined for the expression of p53 nuclear protein by immunohistochemical staining using the monoclonal antibody PAb 1801. 4-Aminobenzoic Acid 297-300 P53 Homo sapiens 215-218 7883998-4 1995 Induced differentiation of the p53-deficient promyelocytic HL-60 cells along the monocytic lineage by phorbol ester or 1a,25 dihydroxyvitamin D3 resulted in a marked increase of both p21WAF1/CIP1/SDI1 mRNA and protein expression due to enhanced mRNA stability. Phorbol Esters 102-115 P53 Homo sapiens 31-34 15492284-4 2004 We found that CDDO-Me not only activated caspase-8 but also induced expression of DRs, particularly DR5, in a p53-independent mechanism. bardoxolone methyl 14-21 P53 Homo sapiens 110-113 7854771-5 1995 Under conditions of both serum deprivation and presence of hydroxyurea, p53 expression was decreased throughout the cell cycle, and the bivariate DNA/p53 distribution pattern during the cell cycle did not change. Hydroxyurea 59-70 P53 Homo sapiens 72-75 7834638-4 1995 We show that p53-independent induction of WAF1/CIP1 occurs in human leukemia cells treated with 12-O-tetradecanoylphorbol-13-acetate, okadaic acid, or IFN-gamma but not with retinoic acid, vitamin D3, or DMSO. Okadaic Acid 134-146 P53 Homo sapiens 13-16 8036011-7 1994 It is evident that H2O2/FeCl3 possesses essentially the same mutagenic specificity for codons 249 and 250 of p53 as bulky carcinogens such as aflatoxin B1, benzo(a)pyrene or heterocyclic amines. Aflatoxin B1 142-154 P53 Homo sapiens 109-112 15486204-6 2004 This study, using gel-mobility-shift assays, was undertaken to examine the interactions of active and latent p53 protein with DNA fragments and oligodeoxyribonucleotide duplexes modified by BBR3464 in a cell free medium and to compare these results with those describing the interactions of these proteins with DNA modified by cisplatin. Oligodeoxyribonucleotides 144-168 P53 Homo sapiens 109-112 15724841-3 2004 Subsequent studies from our laboratory also revealed that the combined use of both UCN-01 and camptothecin induced DNA double strand breaks in p53 mutant tumor cells but not in normal or p53 negative epithelial cells. Camptothecin 94-106 P53 Homo sapiens 143-146 8061893-5 1994 IHC assays revealed nuclear p53 immunostaining in 53% of cases (32 of 60) with PAb1801, 38% (23 of 60) with PAb421, and 32% (19 of 60) with PAb240. pab240 140-146 P53 Homo sapiens 28-31 8061893-10 1994 IHC with PAb240, which is thought to be specific for mutated p53, was positive in 9 cases with demonstrable p53 mutations and in 9 cases with no detectable mutations. pab240 9-15 P53 Homo sapiens 61-64 8061893-10 1994 IHC with PAb240, which is thought to be specific for mutated p53, was positive in 9 cases with demonstrable p53 mutations and in 9 cases with no detectable mutations. pab240 9-15 P53 Homo sapiens 108-111 8018565-0 1994 Tumor-promoting phorbol ester transiently down-modulates the p53 level and blocks the cell cycle. Phorbol Esters 16-29 P53 Homo sapiens 61-64 8018565-1 1994 Activation of the protein kinase C signaling pathway by tumor-promoting phorbol esters, such as 4 beta-phorbol 12-myristate 13-acetate (PMA), induced a decrease in the level of p53 mRNA in several serum-starved human cell lines. Phorbol Esters 72-86 P53 Homo sapiens 177-180 8018565-2 1994 Also, the tumor-promoting phosphatase inhibitor okadaic acid induced a decrease in the p53 mRNA level in the cell lines. Okadaic Acid 48-60 P53 Homo sapiens 87-90 7530828-7 1995 We find that antibodies to two other discrete sites in the core can also, like PAb240, recognize cryptic epitopes and distinguish mutant from wild-type conformations implying that the point mutations found in p53 in human tumours have widespread effects on the folding pattern of the DNA binding domain. pab240 79-85 P53 Homo sapiens 209-212 7970699-4 1994 The DNA damaging agent etoposide induced p53 accumulation only in cells harboring wild-type p53 yet it induced WAF1/Cip1 gene expression in cells carrying wild-type or mutant p53, suggesting the involvement of p53-dependent and independent signaling pathways in the regulation of WAF1/Cip1 gene expression. Etoposide 23-32 P53 Homo sapiens 41-44 7970699-4 1994 The DNA damaging agent etoposide induced p53 accumulation only in cells harboring wild-type p53 yet it induced WAF1/Cip1 gene expression in cells carrying wild-type or mutant p53, suggesting the involvement of p53-dependent and independent signaling pathways in the regulation of WAF1/Cip1 gene expression. Etoposide 23-32 P53 Homo sapiens 92-95 7970699-4 1994 The DNA damaging agent etoposide induced p53 accumulation only in cells harboring wild-type p53 yet it induced WAF1/Cip1 gene expression in cells carrying wild-type or mutant p53, suggesting the involvement of p53-dependent and independent signaling pathways in the regulation of WAF1/Cip1 gene expression. Etoposide 23-32 P53 Homo sapiens 92-95 7970699-4 1994 The DNA damaging agent etoposide induced p53 accumulation only in cells harboring wild-type p53 yet it induced WAF1/Cip1 gene expression in cells carrying wild-type or mutant p53, suggesting the involvement of p53-dependent and independent signaling pathways in the regulation of WAF1/Cip1 gene expression. Etoposide 23-32 P53 Homo sapiens 92-95 15371552-6 2004 Finally, this PNA acted cooperatively with camptothecin treatment both with regard to p53 activity induction as well as cell viability. Camptothecin 43-55 P53 Homo sapiens 86-89 7923116-4 1994 Induction of p53 is also abnormal in AT cells following treatment with methylmethanesulfonate and bleomycin but appears relatively normal following treatment with UV-C irradiation or the topoisomerase inhibitors, etoposide and camptothecin. Etoposide 213-222 P53 Homo sapiens 13-16 7923116-4 1994 Induction of p53 is also abnormal in AT cells following treatment with methylmethanesulfonate and bleomycin but appears relatively normal following treatment with UV-C irradiation or the topoisomerase inhibitors, etoposide and camptothecin. Camptothecin 227-239 P53 Homo sapiens 13-16 7955081-4 1994 These results would indicate that BBN-induced rat urinary bladder carcinomas are similar to human urinary bladder carcinomas with respect to alterations in the p53 and H-ras genes and that p53 gene alterations are relatively early events in rat urinary bladder carcinogenesis induced by BBN treatment. Butylhydroxybutylnitrosamine 34-37 P53 Homo sapiens 160-163 7955081-4 1994 These results would indicate that BBN-induced rat urinary bladder carcinomas are similar to human urinary bladder carcinomas with respect to alterations in the p53 and H-ras genes and that p53 gene alterations are relatively early events in rat urinary bladder carcinogenesis induced by BBN treatment.

Mitomycin 70-81 P53 Homo sapiens 4-7 7903205-1 1994 Aflatoxin B1 has been suggested as a causative agent for a G to T mutation at codon 249 in the p53 gene in human hepatocellular carcinomas (HCC) from southern Africa and Qidong in China. Aflatoxin B1 0-12 P53 Homo sapiens 95-98 15339383-9 2004 The protein level of Cdk4 protein increased at 3 h and then decreased gradually from 6 h, but it was still higher than that in the vehicle cultures at 12 h. The p53 level decreased obviously at 3 h after staurosporine treatment and then seemed to increase at 12 h, but remained lower than that of vehicle cultures. Staurosporine 204-217 P53 Homo sapiens 161-164 8301066-8 1993 Although many HCC patients displaying P53 mutations also suffer from HBV infection, which itself can lead to rearrangements of P53 coding regions or induce the synthesis of viral proteins possibly interacting with p53, the specific G to T transversion within codon 249 of the P53 gene seems to directly reflect the extent of aflatoxin B1 exposure. Aflatoxin B1 325-337 P53 Homo sapiens 38-41 8301066-8 1993 Although many HCC patients displaying P53 mutations also suffer from HBV infection, which itself can lead to rearrangements of P53 coding regions or induce the synthesis of viral proteins possibly interacting with p53, the specific G to T transversion within codon 249 of the P53 gene seems to directly reflect the extent of aflatoxin B1 exposure. Aflatoxin B1 325-337 P53 Homo sapiens 214-217 8089212-10 1994 CONCLUSIONS: Immunostaining of wild type p53 is demonstrable not only in its nuclear form using antibody PAb240 but also in it common cytoplasmic-perinuclear localisation in normal tissues using the PAb248 monoclonal antibody. pab240 105-111 P53 Homo sapiens 41-44 8208536-13 1994 In contrast, the p53 in cell lines with either homozygous 175His or 248His p53 mutations, were unable either to transactivate or bind to the p53 response element. 248his 68-74 P53 Homo sapiens 17-20 15289856-3 2004 Our results demonstrated that diosgenin induced G2/M arrest of cell cycle progression through p21 up-regulation in a p53-independent pathway and strong induction of apoptosis in HEL cells.

Camptothecin 62-74 P53 Homo sapiens 25-28 7907948-6 1994 In particular, we studied the mutability of codons 247-250 of p53 with the mycotoxin aflatoxin B1 (AFB1) in human hepatocytes. Aflatoxin B1 85-97 P53 Homo sapiens 62-65 9419766-11 1994 Treatment of JEG-3 cells with 8-Br-cAMP, which induces genes characteristic of the syncytiotrophoblast, raised BCL-2 protein approximately twofold, whereas p53 mRNA declined. 8-Bromo Cyclic Adenosine Monophosphate 30-39 P53 Homo sapiens 156-159 15208667-4 2004 We have studied here the p53 response to DNA-damaging agents (camptothecin, mitomycin C) in individual cells. Mitomycin 76-87 P53 Homo sapiens 25-28 15265702-2 2004 We have previously demonstrated that an inhibitor of HDAC, sodium butyrate (NaB), induces apoptosis of breast cancer cells in a P53-independent and P21(waf1)-dependent manner. nab 76-79 P53 Homo sapiens 128-131 7905619-0 1994 Mutagenesis of codon 248 of the human p53 tumor suppressor gene by N-ethyl-N-nitrosourea. Ethylnitrosourea 67-88 P53 Homo sapiens 38-41 8302577-2 1994 Cytoplasmic staining of p53 with the monoclonal antibody PAb240 was inhibited by the specific oligopeptide, NTFRHSVVVP, that corresponds to the amino acids between 210 and 219 in p53 and which includes the epitope domain for PAb240. pab240 57-63 P53 Homo sapiens 24-27 15155752-4 2004 We have used the small molecule compound CP-31398 (Pfizer) to restore wild-type p53 function to the codon 248 mutant p53 present in WiT49 cells.

Aflatoxin B1 256-268 P53 Homo sapiens 33-36 15155752-4 2004 We have used the small molecule compound CP-31398 (Pfizer) to restore wild-type p53 function to the codon 248 mutant p53 present in WiT49 cells. CP 31398 41-49 P53 Homo sapiens 117-120 15155752-5 2004 In these cells, CP-31398 activated transcription of p53-regulated promoters and enhanced UV light-induced apoptosis without altering the overall p53 protein level. CP 31398 16-24 P53 Homo sapiens 52-55 15155752-7 2004 Gene expression profiling of CP-31398-treated WiT49 cells revealed subsets of putative p53 target genes that were up- or down-regulated. CP 31398 29-37 P53 Homo sapiens 87-90 15551755-0 2004 2-methoxyestradiol enhances p53 protein transduction therapy-associated inhibition of the proliferation of oral cancer cells through the suppression of NFkappaB activity. 2-Methoxyestradiol 0-18 P53 Homo sapiens 28-31 7690928-5 1993 Mutant p53 proteins were variably resistant to E6-mediated degradation, and this correlated with PAb 1620 reactivity. 4-Aminobenzoic Acid 97-100 P53 Homo sapiens 7-10 8397412-0 1993 Aflatoxin B1 induces the transversion of G-->T in codon 249 of the p53 tumor suppressor gene in human hepatocytes. Aflatoxin B1 0-12 P53 Homo sapiens 70-73 15551755-3 2004 However, the intracellular half-life of the delivered protein was less than 36 h. Previous studies also showed that 2-methoxyestradiol (2-ME), an endogenous non-toxic estrogenic metabolite, induces the stabilization of the wild-type p53 protein in human cancer cells posttranscriptionally. 2-Methoxyestradiol 116-134 P53 Homo sapiens 233-236 15551755-3 2004 However, the intracellular half-life of the delivered protein was less than 36 h. Previous studies also showed that 2-methoxyestradiol (2-ME), an endogenous non-toxic estrogenic metabolite, induces the stabilization of the wild-type p53 protein in human cancer cells posttranscriptionally. 2-Methoxyestradiol 136-140 P53 Homo sapiens 233-236 15551755-4 2004 In the present study, we examined whether 2-ME induced the stabilization of 11R-p53 and had an inhibitory effect on the proliferation of oral cancer cells. 2-Methoxyestradiol 42-46 P53 Homo sapiens 80-83 15551755-5 2004 The application of 2-ME significantly enhanced the inhibitory effect of 11R-p53 on the proliferation of oral cancer cells. 2-Methoxyestradiol 19-23 P53 Homo sapiens 76-79 15551755-8 2004 These results suggest that 2-ME synergistically enhances the 11R-p53-induced inhibition of the proliferation of oral cancer cells through the suppression of NFkB transcription. 2-Methoxyestradiol 27-31 P53 Homo sapiens 65-68 15242777-4 2004 Here, we have found that treatment of pyrrolidine dithiocarbamate (PDTC), a zinc ionophore, resulted in the accumulation of several proteasome substrates including p53 and p21 in HeLa cells. pyrrolidine dithiocarbamic acid 38-65 P53 Homo sapiens 164-167 15242777-4 2004 Here, we have found that treatment of pyrrolidine dithiocarbamate (PDTC), a zinc ionophore, resulted in the accumulation of several proteasome substrates including p53 and p21 in HeLa cells. pyrrolidine dithiocarbamic acid 67-71 P53 Homo sapiens 164-167 15252149-10 2004 Attenuating p53 by a chemical inhibitor pifithrin-alpha decreased the selenite-induced p53 Ser15P and led to concordant reductions of PARP cleavage and apoptosis. ser15p 91-97 P53 Homo sapiens 12-15 15252149-10 2004 Attenuating p53 by a chemical inhibitor pifithrin-alpha decreased the selenite-induced p53 Ser15P and led to concordant reductions of PARP cleavage and apoptosis. ser15p 91-97 P53 Homo sapiens 87-90 15252149-11 2004 In summary, selenite-induced p53 Ser15P appeared to be important for activating the caspase-mediated apoptosis involving both the caspase-8 and the caspase-9 pathways in the LNCaP cells. ser15p 33-39 P53 Homo sapiens 29-32 14988151-6 2004 Furthermore, p53 gene silencing resulted in decreased p21 mRNA levels and reduced the sensitivity of CD34+ cells toward the cytotoxic drug etoposide. Etoposide 139-148 P53 Homo sapiens 13-16 15149862-1 2004 Mutations in the WRN or the TP53 genes lead to spontaneous genetic instability, an elevated risk of tumor formation, and sensitivity to compounds that interfere with DNA replication, such as camptothecin and DNA interstrand cross-linking drugs.

Mitomycin 156-167 P53 Homo sapiens 14-17 8485705-5 1993 The increase in p53 activation in camptothecin treated cells may result, at least in part, from an increased half-life of the protein and consequent increases in intracellular protein concentration.

Aflatoxin B1 168-180 P53 Homo sapiens 30-33 12894226-3 2003 In the present study, we report that EGCG-induced apoptosis in human prostate carcinoma LNCaP cells is mediated via modulation of two related pathways: (a) stabilization of p53 by phosphorylation on critical serine residues and p14ARF-mediated downregulation of murine double minute 2(MDM2) protein, and (b) negative regulation of NF-kappaB activity, thereby decreasing the expression of the proapoptotic protein Bcl-2. epigallocatechin gallate 37-41 P53 Homo sapiens 173-176 1384667-4 1992 We report here the detection of loss of heterozygosity at the TP53 locus in various human cancers by using a highly informative dinucleotide repeat polymorphism. Dinucleoside Phosphates 128-140 P53 Homo sapiens 62-66 12894226-4 2003 EGCG-induced stabilization of p53 caused an upregulation in its transcriptional activity, thereby resulting in activation of its downstream targets p21/WAF1 and Bax. epigallocatechin gallate 0-4 P53 Homo sapiens 30-33 12894226-5 2003 Thus, EGCG had a concurrent effect on two important transcription factors p53 and NF-kappaB, causing a change in the ratio of Bax/Bcl-2 in a manner that favors apoptosis. epigallocatechin gallate 6-10 P53 Homo sapiens 74-77 12750388-9 2003 The effect of p53 and p73alpha on cell migration was mediated through the activity of the phosphatidylinositol 3-kinase/Rac1 pathway.

Aflatoxin B1 0-12 P53 Homo sapiens 95-98 1310637-7 1992 The occurrence of mutation in codon 249 of the p53 gene in selective samples of human hepatocellular cancers may indicate involvement of environmental carcinogens other than aflatoxin B1 or that hepatitis B virus-related hepatitis is a prerequisite for aflatoxin B1 induction of G to T transversion in codon 249. Aflatoxin B1 174-186 P53 Homo sapiens 47-50 12721303-2 2003 Previous evidence has shown that apoptotic death of embryonic cortical neurons treated with the DNA damaging agent camptothecin is dependent upon the tumor suppressor p53, an upstream death mediator, and more distal death effectors such as caspases. Camptothecin 115-127 P53 Homo sapiens 167-170 1565469-1 1992 We investigated the immunocytochemical staining and immunoblotting characteristics of 33 different p53 mutant proteins identified in lung cancer cell lines (18 small-cell lung cancer and 15 non-small-cell lung cancer) using monoclonal antibodies pAbs 240, 421 and 1801. 4-Aminobenzoic Acid 246-250 P53 Homo sapiens 99-102 12839945-4 2003 PTEN and LY294002 induced p53 activity in human brain endothelial cells, suggesting that PTEN and PI3K pathways can suppress the progression of cancer through direct actions on tumor and endothelial cells. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 9-17 P53 Homo sapiens 26-29 1332185-3 1992 Recent reports of a guanine to thymine mutation of the third base of codon 249 of the tumour suppressor gene, p53, in 50% of patients with hepatocellular carcinoma in regions of high aflatoxin exposure, and mutagenic experiments showing that aflatoxin B1 binds particularly to guanine residues in G-C-rich domains and that codon 249 is a preferred target have suggested a mechanism whereby aflatoxin might induce malignant transformation. Aflatoxin B1 242-254 P53 Homo sapiens 110-113 1370482-3 1992 The fidelity of this mimicry by okadaic acid extends to the phosphorylation of the 27 hsp complex, stathmin, eIF-4E, myosin light chain, nucleolin, epidermal growth factor receptor, and other cdc2-kinase substrates (c-abl, RB, and p53). Okadaic Acid 32-44 P53 Homo sapiens 231-234 1873816-7 1991 Immunocytochemical data indicate that prostate carcinoma cells expressing the transfected wild-type p53 gene are growth arrested because they exhibit a reduced level of thymidine incorporation into DNA.

Hesperidin 0-10 P53 Homo sapiens 72-75 35478958-7 2022 Our in vitro results showed that hesperidin partially reversed dexamethasone-induced inhibition of osteogenic differentiation by suppressing the activation of p53, and suggest that hesperidin may be a promising candidate for the treatment against dexamethasone-induced osteoporosis. Hesperidin 33-43 P53 Homo sapiens 159-162 35478958-7 2022 Our in vitro results showed that hesperidin partially reversed dexamethasone-induced inhibition of osteogenic differentiation by suppressing the activation of p53, and suggest that hesperidin may be a promising candidate for the treatment against dexamethasone-induced osteoporosis. Hesperidin 181-191 P53 Homo sapiens 159-162 12067251-5 2002 We employed a yeast reporter system to determine whether PAH o-quinones or the ROS they generate cause change-in-function mutations in p53. pah o-quinones 57-71 P53 Homo sapiens 135-138 35406381-7 2022 Dasatinib treatment also preferentially slowed the growth of gastric and mammary organoids harbouring both Cdh1 and Tp53 mutations. Dasatinib 0-9 P53 Homo sapiens 116-120 12067251-10 2002 p53 mutagenesis by BP-7,8-dione was attenuated by ROS scavengers and completely abrogated by a combination of superoxide dismutase and catalase, indicating that both superoxide anion and hydroxyl radicals were the responsible mutagens. Hydroxyl Radical 187-204 P53 Homo sapiens 0-3 35192728-4 2022 Together with extended tumor exposure to therapeutically effective drug levels via reversible conjugation to Pluronic F-108 (PF108), these features translated into rapid tumor regression and long-term survival in models of both ABCG2-overexpressing and p53-mutant high-risk neuroblastomas, in contrast to a marginal effect of the clinically used camptothecin derivative, irinotecan. Poloxamer 125-130 P53 Homo sapiens 253-256 35192728-4 2022 Together with extended tumor exposure to therapeutically effective drug levels via reversible conjugation to Pluronic F-108 (PF108), these features translated into rapid tumor regression and long-term survival in models of both ABCG2-overexpressing and p53-mutant high-risk neuroblastomas, in contrast to a marginal effect of the clinically used camptothecin derivative, irinotecan. Camptothecin 346-358 P53 Homo sapiens 253-256 35217496-9 2022 CONCLUSIONS: Taken together, we show that DLG2 over expression increases p53 mediated apoptosis in response to etoposide and UVC mediated genotoxicity and reduced DNA replication machinery. Etoposide 111-120 P53 Homo sapiens 73-76 12067251-14 2002 Together these data suggest that PAH o-quinones generate an endogenous mutagen (ROS) which leads to p53 inactivation. pah o-quinones 33-47 P53 Homo sapiens 100-103 12010862-0 2002 XRCC1 and CYP2E1 polymorphisms as susceptibility factors of plasma mutant p53 protein and anti-p53 antibody expression in vinyl chloride monomer-exposed polyvinyl chloride workers.

Glutamine 74-77 P53 Homo sapiens 113-116 12010862-9 2002 Individuals having experienced a high VCM exposure and displaying a XRCC1 Gln-Gln genotype had a highest risk of p53 overexpression among those having different combinations of VCM exposure and XRCC1 genotypes (OR, 6.5; 95% CI, 1.7-24.2). Glutamine 78-81 P53 Homo sapiens 113-116 35007916-16 2022 The protein levels of P53 and Caspase 3 increased with BA, NaB and SPT treatment for 72 h. CONCLUSIONS: BA, NaB and SPT show anti-cancer activity in the DMS-114 cell line without damaging MRC-5 cells, and some of the molecular mechanisms are involved in apoptosis and cell cycle arrest. nab 59-62 P53 Homo sapiens 22-25 11956160-12 2002 These regions contain consensus binding sites for p53 and GATA, respectively, but mutational analyses and gel shift assays suggested that, while the p53 response element is required for NaB responsiveness, neither p53 nor GATA are involved. nab 186-189 P53 Homo sapiens 149-152 35007916-16 2022 The protein levels of P53 and Caspase 3 increased with BA, NaB and SPT treatment for 72 h.

Etoposide 0-9 P53 Homo sapiens 45-48 35178190-4 2022 We assessed the impact of the loss of p53 function on the formation of DNA damage induced by the Top2 poison etoposide. Etoposide 109-118 P53 Homo sapiens 38-41 35178190-5 2022 Using human HCT116 cells, we found resistance to etoposide in cell growth assays upon the functional loss of p53. Etoposide 49-58 P53 Homo sapiens 109-112 35178190-6 2022 Nonetheless, cells lacking fully functional p53 were etoposide hypersensitive in clonogenic survival assays. Etoposide 53-62 P53 Homo sapiens 44-47 35071802-8 2022 PfHz treatment for 24 h significantly altered expression for 14 genes: 12 were down-regulated (ANAPC11, BRCC3, CUL4B, FBXO4, MIB1, SKP2, TP53, UBA2, UBA3, UBE2G1, UBE2G2, and WWP1), while 2 were up-regulated (UBE2J1 and UBE2Z). pfhz 0-4 P53 Homo sapiens 137-141 35178190-9 2022 Employing genome-wide siRNA screens, we identified a set of genes for which reduced expression resulted in enhanced synthetic lethality upon etoposide treatment of p53 defective cells. Etoposide 141-150 P53 Homo sapiens 164-167 11956160-12 2002 These regions contain consensus binding sites for p53 and GATA, respectively, but mutational analyses and gel shift assays suggested that, while the p53 response element is required for NaB responsiveness, neither p53 nor GATA are involved. nab 186-189 P53 Homo sapiens 149-152 35178190-10 2022 We focused on one hit from this screen, ATR, and showed that decreased expression sensitized the p53-defective cells to etoposide in all assays and generated elevated levels of Top2cc in both p53 proficient and deficient cells. Etoposide 120-129 P53 Homo sapiens 97-100 12054599-0 2002 Restoration of p53 tumor suppressor pathway in human cervical carcinoma cells by sodium arsenite. sodium arsenite 81-96 P53 Homo sapiens 15-18 35280362-13 2022 Conclusions: In contrast to most previous studies, we revealed TP53-MUT characteristic in NSCLC patients according to histology-specific differences and the association between TP53-MUT and the mutation landscape, the TMB, and the OS. 1,2,4,5-tetramethoxybenzene 218-221 P53 Homo sapiens 63-67 12054599-5 2002 Two p53-responsive genes, p21(waf1/cip1) and mdm2, were induced after SA treatment. sodium arsenite 70-72 P53 Homo sapiens 4-7 12054599-7 2002 SA-induced apoptosis was greatly reduced by expression of a dominant-negative mutated p53. sodium arsenite 0-2 P53 Homo sapiens 86-89 12054599-8 2002 In this study, we have first demonstrated that SA did repress E6 and E7 oncogenes, restore the p53 tumor suppressor pathway and induce apoptosis in SiHa cells. sodium arsenite 47-49 P53 Homo sapiens 95-98 11896693-2 2002 A disproportionate number of mutations are found in certain codons of the p53 gene, mostly at CpG dinucleotide sequences, which are highly methylated in human tissues. Dinucleoside Phosphates 98-110 P53 Homo sapiens 74-77 35111281-6 2022 TMB was associated with ALK (p = 0.01), EGFR (p < 0.01), and TP53 (p < 0.05) alterations. 1,2,4,5-tetramethoxybenzene 0-3 P53 Homo sapiens 61-65 11827710-0 2002 Pifithrin-alpha, an inhibitor of p53, enhances the genetic instability induced by etoposide (VP16) in human lymphoblastoid cells treated in vitro. Etoposide 82-91 P53 Homo sapiens 33-36 11827710-0 2002 Pifithrin-alpha, an inhibitor of p53, enhances the genetic instability induced by etoposide (VP16) in human lymphoblastoid cells treated in vitro. Etoposide 93-97 P53 Homo sapiens 33-36 11844817-5 2002 Induction of RNA and protein expression of the p53 target gene p21/WAF1 was demonstrated in samples from patients treated with SCH 58500 instillation at higher dose levels. sch 58500 127-136 P53 Homo sapiens 47-50 11841447-7 2002 We found that the expression of the cell cycle checkpoint protein Chk1 was reduced in the etoposide-treated p53-transfected cells by 24 h, and this correlated with a reduction in the extent of etoposide-induced phosphorylation of CDK1 at tyrosine 15 (Y15). Etoposide 193-202 P53 Homo sapiens 108-111 11841447-8 2002 We conclude, therefore, that p53 overrides the strong G2 checkpoint response to etoposide in K562 cells, by directly or indirectly downregulating Chk1 expression, which, in turn, contributes to the proapoptotic effect of p53. Etoposide 80-89 P53 Homo sapiens 29-32 11841447-8 2002 We conclude, therefore, that p53 overrides the strong G2 checkpoint response to etoposide in K562 cells, by directly or indirectly downregulating Chk1 expression, which, in turn, contributes to the proapoptotic effect of p53. Etoposide 80-89 P53 Homo sapiens 221-224 12174820-1 2002 CP-31398, a styrylquinazoline, emerged from a screen for therapeutic agents that restore a wild-type DNA-binding conformation of mutant p53 to suppress tumors in-vivo (Science 286, 2507, 1999). CP 31398 0-8 P53 Homo sapiens 136-139 12174820-6 2002 Interestingly, we found that wild-type p53 protein is stabilized upon CP-31398 exposure. CP 31398 70-78 P53 Homo sapiens 39-42 12174820-7 2002 p53 target genes such as p21WAF1/Cip1, and KILLER/DR5 were upregulated by CP-31398, but their expression did not correlate with arrest or apoptosis induction. CP 31398 74-82 P53 Homo sapiens 0-3 12174820-8 2002 Combination of CP-31398 and TRAIL or chemotherapeutic agents enhanced cancer cell killing effect possibly through upregulation of p53-regulated genes such as KILLER/DR5. CP 31398 15-23 P53 Homo sapiens 130-133 12174820-9 2002 Bax-/-, wild-type p53-expressing cells displayed reduced susceptibility to killing by CP-31398. CP 31398 86-94 P53 Homo sapiens 18-21 12467212-11 2002 In addition, no correlation was found between cell sensitivity to CDDO-Me and p53 status, suggesting that CDDO-Me induce a p53-independent apoptosis. bardoxolone methyl 106-113 P53 Homo sapiens 123-126 11741290-8 2001 This is the first demonstration that camptothecin and Zeocin can differentially signal for increased levels of modified p53 during all stages of the cell cycle.

Etoposide 23-32 P53 Homo sapiens 0-3 11684284-1 2001 We investigated whether p53, being a redox-sensitive protein, has a role in the responsiveness of AML cells to etoposide. Etoposide 111-120 P53 Homo sapiens 24-27 11684284-6 2001 After etoposide exposure for up to 24 hours, some nuclear accumulation of p53 was observed in the ER subclone, as analysed by Western blotting. Etoposide 6-15 P53 Homo sapiens 74-77 11602746-6 2001 We demonstrate that p53 plays an essential role in the MVMp-induced cell cycle arrest in both S and G(2) by using p53 wild-type (+/+) and null (-/-) cells. mvmp 55-59 P53 Homo sapiens 20-23 11602746-6 2001 We demonstrate that p53 plays an essential role in the MVMp-induced cell cycle arrest in both S and G(2) by using p53 wild-type (+/+) and null (-/-) cells. mvmp 55-59 P53 Homo sapiens 114-117 11602746-8 2001 Together these results show that the MVMp-induced cell cycle arrest in S is p53 dependent but p21(cip1) independent, whereas the arrest in G(2) depends on both p53 and its downstream effector p21(cip1). mvmp 37-41 P53 Homo sapiens 76-79 11602746-8 2001 Together these results show that the MVMp-induced cell cycle arrest in S is p53 dependent but p21(cip1) independent, whereas the arrest in G(2) depends on both p53 and its downstream effector p21(cip1). mvmp 37-41 P53 Homo sapiens 160-163 11591730-5 2001 Induction of neuronal cell death by camptothecin, a DNA-damaging agent that functions through a p53-dependent mechanism, resulted in increased Apaf1 mRNA in p53-positive, but not p53-deficient neurons. Camptothecin 36-48 P53 Homo sapiens 96-99 11591730-5 2001 Induction of neuronal cell death by camptothecin, a DNA-damaging agent that functions through a p53-dependent mechanism, resulted in increased Apaf1 mRNA in p53-positive, but not p53-deficient neurons. Camptothecin 36-48 P53 Homo sapiens 157-160 11591730-5 2001 Induction of neuronal cell death by camptothecin, a DNA-damaging agent that functions through a p53-dependent mechanism, resulted in increased Apaf1 mRNA in p53-positive, but not p53-deficient neurons. Camptothecin 36-48 P53 Homo sapiens 157-160 11576999-13 2001 Since over 50% of human tumors contain a functionally defective p53 that reduces sensitivity to commonly used chemotherapeutic agents, such as etoposide and cisplatin, the ability of tachpyridine to induce apoptosis independently of p53 may offer an advantage in anti-tumor therapy. Etoposide 143-152 P53 Homo sapiens 64-67 11562347-3 2001 Dexamethasone (Dex) stimulates the degradation of endogenous GR and p53 by the proteasome pathway in HUVEC under hypoxia and mitomycin C treatments, and also in hepatoma cells (HepG2) under normoxia.

Hydroxyurea 34-45 P53 Homo sapiens 92-95 11522624-3 2001 In the present study, we have used a highly sensitive mutation assay to determine the p53 mutation load in nontumorous human lung and to study the mutability of p53 codons 157, 248, 249, and 250 to benzo(a)pyrene-diol-epoxide (BPDE), an active metabolite of BP in human bronchial epithelial BEAS-2B cells. pyrene-diol-epoxide 206-225 P53 Homo sapiens 161-164 11555596-8 2001 Competition analysis with monoclonal antibodies showed that Fab binding could be inhibited most effectively with DO11 and, to a lesser extent, Pab240, indicating an epitope within or adjacent to residues 181-190 of p53. pab240 143-149 P53 Homo sapiens 215-218 11602059-7 2001 Cytotoxicity assays revealed that the wt-p53 transfectants were more sensitive to doxorubicin and mitomycin compared with the pNeo transformants. Mitomycin 98-107 P53 Homo sapiens 41-44 11479920-11 2001 Given the fact that p53 mutations are common in patients with metastatic prostate cancer, our finding that 2-ME-mediated growth inhibition of human prostate cancer cells occurred in a p53-independent manner has considerable clinical significance. 2-Methoxyestradiol 107-111 P53 Homo sapiens 184-187 11396965-3 2001 In stably transfected DLD-1 colorectal adenocarcinoma cells, cdc25C expression is down-regulated when p53 is induced from a (tet)-off-regulated system. tetramethylenedisulfotetramine 125-128 P53 Homo sapiens 102-105 11423970-8 2001 Low concentrations of roscovitine cooperate with the DNA-damaging agent camptothecin to activate p53 in a synergistic fashion. Camptothecin 72-84 P53 Homo sapiens 97-100 11350911-9 2001 Induction of wt p53 in these models led to a 3- and 2-fold increase in sensitivity to 1,3-bis(2-chloroethyl)-1-nitrosourea and temozolomide, respectively, which generate the MGMT-repairable O(6)-alkyl adducts in DNA. o(6)-alkyl 190-200 P53 Homo sapiens 16-19 11706756-2 2001 The aim of this study was to determine the predictive value of p53 mutation or the expression of GML, a target of p53, for sensitivity to 5-FU and MMC. Mitomycin 147-150 P53 Homo sapiens 63-66 11706756-2 2001 The aim of this study was to determine the predictive value of p53 mutation or the expression of GML, a target of p53, for sensitivity to 5-FU and MMC. Mitomycin 147-150 P53 Homo sapiens 114-117 11706756-9 2001 CONCLUSION: GML expression and p53 mutation in colorectal cancer may be useful predictive genetic markers for sensitivity to MMC and 5-FU, respectively.

Etoposide 46-55 P53 Homo sapiens 18-21 11313880-7 2001 In contrast, human glioma cells lacking functional p53, either due to mutation or the expression of E6 protein of human papillomavirus, were highly resistant to etoposide and exhibited no significant change in the ceramide level. Etoposide 161-170 P53 Homo sapiens 51-54 11267976-5 2001 The results suggest that NaB blocks the growth of both cell lines by induction of cyclin-dependent kinase inhibitors (in particular, p21(waf1) in NCI-H23 and p27(kip1) and p16(ink4) in NCI-H460) through a p53-dependent or p53-independent mechanism, and open up interesting perspectives for the use of NaB as an alternative or additional strategy in the treatment of non-small cell lung carcinoma. nab 25-28 P53 Homo sapiens 205-208 11267976-5 2001 The results suggest that NaB blocks the growth of both cell lines by induction of cyclin-dependent kinase inhibitors (in particular, p21(waf1) in NCI-H23 and p27(kip1) and p16(ink4) in NCI-H460) through a p53-dependent or p53-independent mechanism, and open up interesting perspectives for the use of NaB as an alternative or additional strategy in the treatment of non-small cell lung carcinoma. nab 25-28 P53 Homo sapiens 222-225 11342237-0 2001 SeO(2) induces apoptosis with down-regulation of Bcl-2 and up-regulation of P53 expression in both immortal human hepatic cell line and hepatoma cell line. seo(2) 0-6 P53 Homo sapiens 76-79 11342237-3 2001 SeO(2) could also down-regulate the Bcl-2 level, greatly in HL-7702 and slightly in SMMC-7721 cells, but up-regulate wild type P53 level a little in HL-7702 and significantly in SMMC-7721 cells. seo(2) 0-6 P53 Homo sapiens 127-130 11342237-4 2001 The Bcl-2/P53 value was closely correlated with the apoptotic rate as well as SeO(2) concentrations. seo(2) 78-84 P53 Homo sapiens 10-13 11096068-5 2001 Here we show that genistein induces the up-regulation of p53 protein, phosphorylation of p53 at serine 15, activation of the sequence-specific DNA binding properties of p53, and phosphorylation of the hCds1/Chk2 protein kinase at threonine 68. Genistein 18-27 P53 Homo sapiens 57-60 11096068-5 2001 Here we show that genistein induces the up-regulation of p53 protein, phosphorylation of p53 at serine 15, activation of the sequence-specific DNA binding properties of p53, and phosphorylation of the hCds1/Chk2 protein kinase at threonine 68. Genistein 18-27 P53 Homo sapiens 89-92 11096068-5 2001 Here we show that genistein induces the up-regulation of p53 protein, phosphorylation of p53 at serine 15, activation of the sequence-specific DNA binding properties of p53, and phosphorylation of the hCds1/Chk2 protein kinase at threonine 68. Genistein 18-27 P53 Homo sapiens 89-92 11096068-7 2001 In contrast, the topoisomerase II inhibitor etoposide induced phosphorylation of p53 and Chk2 in ATM-positive and ATM-deficient cells. Etoposide 44-53 P53 Homo sapiens 81-84 11096068-9 2001 Together our data suggest that ATM is required for activation of a DNA damage-induced pathway that activates p53 and Chk2 in response to genistein. Genistein 137-146 P53 Homo sapiens 109-112 11258706-1 2001 The N-terminal BOX-I domain of p53 containing a docking site for the negative regulator MDM2 and the positive effector p300, harbours two recently identified phosphorylation sites at Thr18 or Ser20O whose affect on p300 is undefined. ser20o 192-198 P53 Homo sapiens 31-34 11158590-2 2001 We have examined the response to p53 when DNA synthesis is blocked by hydroxyurea (HU) or aphidicolin or when DNA is damaged by gamma IR. Hydroxyurea 70-81 P53 Homo sapiens 33-36 11148027-0 2001 Chalcone derivatives antagonize interactions between the human oncoprotein MDM2 and p53.

Oligodeoxyribonucleotides 37-58 P53 Homo sapiens 93-96 11299762-5 2001 Collectively, these observations suggest that growth inhibition by ellagic acid is mediated by signaling pathways that mediate DNA damage, triggers p53, which in turn activates p21 and at the same time alters the growth factor expression, resulting in the down regulation of IGF-II. Ellagic Acid 67-79 P53 Homo sapiens 148-151 11196182-2 2001 A specific missense mutation resulting from a guanine to thymine transversion at the third position of codon 249 in the p53 tumor suppressor gene has been reported in 10-70% of HCCs from areas of high dietary exposure to aflatoxin B1. Aflatoxin B1 221-233 P53 Homo sapiens 120-123 11140901-5 2001 A significant correlation was observed between MDM2 protein and p53 expression in 38 cases with an areca quid (AQ) chewing habit (P=0.032). aq 111-113 P53 Homo sapiens 64-67 11125034-0 2001 MDM2 mediated nuclear exclusion of p53 attenuates etoposide-induced apoptosis in neuroblastoma cells. Etoposide 50-59 P53 Homo sapiens 35-38 11125034-3 2001 Data presented here indicate that hyperactive nuclear export of p53 suppresses etoposide-induced apoptosis but does not prevent growth arrest. Etoposide 79-88 P53 Homo sapiens 64-67 11125034-5 2001 Our data show etoposide induces complete trans-location of p53 to the nucleus and activation of apoptosis in the neuroblastic NB cell line SH-SY5Y (N-type), which expresses low levels of MDM2. Etoposide 14-23 P53 Homo sapiens 59-62 11125034-11 2001 These results demonstrate for the first time that hyperactive nuclear export of p53 attenuates chemotherapy-induced apoptosis in NB cells, and our findings suggest that inhibitors of MDM2 may enhance the therapeutic efficacy of etoposide by promoting apoptosis rather than trans-differentiation. Etoposide 228-237 P53 Homo sapiens 80-83 11093826-4 2000 TSA enhanced the protein expression of p21(WAF1), CREB-binding protein, cyclinE, cyclin A, Bak and Bax, while it reduced the expression of E2F-1, E2F-4, HDAC1, p53 and hyperphosphorylated form of Rb. trichostatin A 0-3 P53 Homo sapiens 160-163 11329882-5 2000 These findings suggest that butyrolactone I prevents apoptosis by the direct inhibition of CDK and also, possibly, by CDK-inhibition through p53-independent p21-induction. 4-Butyrolactone 28-41 P53 Homo sapiens 141-144 11102893-8 2000 SDNA was greater in p53-positive and bcl-2-negative cases; SDNP was greater in p53-positive cases; SHF was lower in p53- and c-myc-positive cases. sdnp 59-63 P53 Homo sapiens 79-82 11102893-8 2000 SDNA was greater in p53-positive and bcl-2-negative cases; SDNP was greater in p53-positive cases; SHF was lower in p53- and c-myc-positive cases. sdnp 59-63 P53 Homo sapiens 79-82 11071927-5 2000 In DLD-1 colorectal adenocarcinoma cells (DLD-1-tet-off-p53) cyclin B1 and B2 mRNA levels drop after expression of wild-type p53 but not after induction of a DNA binding-deficient mutant of p53. tetramethylenedisulfotetramine 48-51 P53 Homo sapiens 56-59 10884389-2 2000 In this study, we show that BRCA1 is initially up-regulated, followed by a reduction to below basal levels in response to treatment with the DNA-damaging agents adriamycin and mitomycin C, and that the reduction of BRCA1 expression is dependent on the presence of wild-type p53. Mitomycin 176-187 P53 Homo sapiens 274-277 10996201-8 2000 Our findings suggest that down regulation of topo IIalpha in association with p53 deficiency can confer chromosomal instability in etoposide-resistant K562 cells. Etoposide 131-140 P53 Homo sapiens 78-81 11070152-4 2000 Immunohistochemistry of FGF1, FGF2, FGFR1 and p53 used avidin-biotin detection of the primary antibody. avidin-biotin 55-68 P53 Homo sapiens 46-49 10951577-7 2000 The antioxidant N-acetylcysteine and the Cu/Zn superoxide dismutase inhibitor diethyldithiocarbamic acid abolished the hypoxia-induced increases in ROS and p53 levels.

Etoposide 24-33 P53 Homo sapiens 10-13 10908664-4 2000 Derangement of its transcriptional activity manifested as inhibition of p53-mediated apoptosis by etoposide, a representative antineoplastic agent. Etoposide 98-107 P53 Homo sapiens 72-75 10856831-2 2000 AGG to AGT transversion in codon 249 of exon 7 of the p53 gene occurs in over 50% of HCC from endemic regions, where both chronic infection with the hepatitis B virus (HBV) and exposure to carcinogens such as aflatoxin B1 (AFB1) prevail. Aflatoxin B1 209-221 P53 Homo sapiens 54-57 10866313-7 2000 Perturbation of mitochondrial function mediated accumulation of wild-type p53 protein, since Bcl-2 overexpression, bongkrekic acid, or inhibition of mitochondrial protein synthesis with chloramphenicol strongly reduced TK/GCV-induced accumulation of wild-type p53 protein. Chloramphenicol 186-201 P53 Homo sapiens 74-77 10863098-0 2000 Mutations in the p53 tumor suppressor gene in tree shrew hepatocellular carcinoma associated with hepatitis B virus infection and intake of aflatoxin B1.

Mitomycin 101-104 P53 Homo sapiens 0-3 10757806-5 2000 Although normal cells and wild-type p53-expressing tumor cells showed similar responses to actinomycin D and camptothecin treatment, the transcriptional activity of stabilized p53 induced by deferoxamine mesylate, which mimics hypoxia, in normal cells was lost in all three tumor cell lines tested. Camptothecin 109-121 P53 Homo sapiens 36-39 10738214-1 2000 BACKGROUND: Specific mutations of the p53 tumor suppressor gene in hepatocellular carcinoma (HCC) have been reported from several parts of the world, but to the authors" knowledge to date the status of this gene has not been studied in HCC patients in India, where HCC is one of the major cancers and the frequency of chronic hepatitis B virus (HBV) as well as hepatitis C virus (HCV) infection and exposure to dietary aflatoxin B(1) is very high. Aflatoxin B1 419-430 P53 Homo sapiens 38-41 10699888-1 2000 BACKGROUND: This study examined the effect of tegafur, a depot of 5-fluorouracil, in human colorectal carcinomas in terms of apoptosis, cell proliferation, and expression of p53 gene and angiogenesis-related molecules. Tegafur 46-53 P53 Homo sapiens 174-177 10741907-10 2000 Meanwhile, Ad-p53 gene transfer combined with taxol, cisplatin, doxorubicin or mitomycin C was shown to be even more effective in suppressing growth in the two cell lines. Mitomycin 79-90 P53 Homo sapiens 14-17 10820956-1 2000 BACKGROUND AND PURPOSE: In our previous study, positive p53 staining was observed in 47 of 81 (58%) cases of oral squamous cell carcinoma associated with areca quid (AQ) chewing and cigarette smoking. aq 166-168 P53 Homo sapiens 56-59 10820956-2 2000 This study looked for expression of p53 protein in premalignant oral lesions in patients who chewed AQ or smoked cigarettes, or both. aq 100-102 P53 Homo sapiens 36-39 10820956-9 2000 CONCLUSIONS: These results demonstrate that p53 is often present in precancerous lesions of patients who chew AQ and smoke cigarettes. aq 110-112 P53 Homo sapiens 44-47 10940651-2 2000 Although all the cell lines have a wild-type (wt) p53 gene, the protein is in a mutant conformation detectable by the anti-p53 antibody PAb 240. 4-Aminobenzoic Acid 136-139 P53 Homo sapiens 123-126 10940651-6 2000 The conformation of p53 remained unchanged, being detectable in flow cytometry by PAb 240, but not by PAb 1620 (an antibody which only detects p53 in wt conformation). 4-Aminobenzoic Acid 82-85 P53 Homo sapiens 20-23 10663644-5 2000 RESULTS: UCN-01, a specific inhibitor of protein kinase C (PKC) presently in clinical trials, abrogated CPT-induced activation of S and G(2) checkpoints in human MDA-MB-231 and GI 101A breast carcinoma cells, both of which are mutants for the p53 gene. Camptothecin 104-107 P53 Homo sapiens 243-246 26368609-5 2000 Recent molecular studies of p53 tumor suppressor gene mutations and p53 protein expression in the lungs of patients with lung cancer and occupational exposure to crystalline silica and other dusts have been conducted.

Cobalt 11-17 P53 Homo sapiens 44-47 22607421-6 2000 Nickel and cobalt ions inhibited binding of p53 to scDNA and to p53CON in linear DNA fragments less efficiently than zinc. Cobalt 11-17 P53 Homo sapiens 64-67 11173660-4 2000 Protein p53 accumulation was detected by the streptavidin-biotin method using DO-7 (Dako) antibody. do-7 78-82 P53 Homo sapiens 8-11 10606504-2 1999 As a method for approaching the mechanism of tumor promoter function, the ability of oxidative DNA damage by BzPO was investigated by using (32)P-labeled DNA fragments obtained from the human p53 tumor suppressor gene and c-Ha-ras-1 protooncogene. Benzoyl Peroxide 109-113 P53 Homo sapiens 192-195 10585266-5 1999 p53(V143A) inhibited the camptothecin-induced accumulation of p21(WAF1/CIP1) in cell lines with p53 functional wild-type activity, but not in cell lines lacking p53 activity, consistent with a transdominant-negative effect of p53(V143A). Camptothecin 25-37 P53 Homo sapiens 0-3 10585266-5 1999 p53(V143A) inhibited the camptothecin-induced accumulation of p21(WAF1/CIP1) in cell lines with p53 functional wild-type activity, but not in cell lines lacking p53 activity, consistent with a transdominant-negative effect of p53(V143A). Camptothecin 25-37 P53 Homo sapiens 96-99 10585266-5 1999 p53(V143A) inhibited the camptothecin-induced accumulation of p21(WAF1/CIP1) in cell lines with p53 functional wild-type activity, but not in cell lines lacking p53 activity, consistent with a transdominant-negative effect of p53(V143A). Camptothecin 25-37 P53 Homo sapiens 96-99 10585266-5 1999 p53(V143A) inhibited the camptothecin-induced accumulation of p21(WAF1/CIP1) in cell lines with p53 functional wild-type activity, but not in cell lines lacking p53 activity, consistent with a transdominant-negative effect of p53(V143A). Camptothecin 25-37 P53 Homo sapiens 96-99 10544021-3 1999 In the present study, we showed that the topoisomerase II inhibitor of widely used anticancer drugs etoposide and doxorubicin activated wt p53 in BL2, a Burkitt"s lymphoma cell line which overexpressed MDM2. Etoposide 100-109 P53 Homo sapiens 139-142 10544021-8 1999 This p53 was co-immunoprecipitated with MDM2, but p53 activated by etoposide or doxorubicin barely complexed with MDM2. Etoposide 67-76 P53 Homo sapiens 5-8 10544021-8 1999 This p53 was co-immunoprecipitated with MDM2, but p53 activated by etoposide or doxorubicin barely complexed with MDM2.

Staurosporine 102-115 P53 Homo sapiens 88-91 10529369-1 1999 Overexpression of the tumor suppressor p53 in HeLa cells leads to loss of the estradiol- and genistein-induced human estrogen receptor (ERalpha) transactivity. Genistein 93-102 P53 Homo sapiens 39-42 10486243-4 1999 An in vitro study was carried out to determine whether p53 could be mutated at position 277 so that it binds preferentially to a sequence containing thymine or cytidine. Cytidine 160-168 P53 Homo sapiens 55-58 11776565-4 1999 RESULTS: Genistein could inhibit proliferation of human breast carcinoma cells with different ER status and p53 status. Genistein 9-18 P53 Homo sapiens 108-111 11776565-8 1999 CONCLUSION: The inhibitory effect of genistein on cell proliferation of breast cancer appears to be due to p21WAF1/CIP1 expression and apoptosis through mechanism independent of ER and p53. Genistein 37-46 P53 Homo sapiens 185-188 10458704-0 1999 Site-specific synthesis of aflatoxin B(1) adducts within an oligodeoxyribonucleotide containing the human p53 codon 249 sequence.

Oligodeoxyribonucleotides 60-84 P53 Homo sapiens 106-109 10402229-3 1999 A lower level of p53 was induced in CDK inhibitor-expressing etoposide-exposed cells suggesting that protection may be due to lower levels of DNA damage in the growth arrested cells. Etoposide 61-70 P53 Homo sapiens 17-20 10389750-2 1999 The relation between aflatoxin B1 (AFB1 )-related hepatocellular carcinomas (HCCs) and hot spot at codon 249 of the p53 gene has received a great deal of attention, but its significance is still controversial. Aflatoxin B1 21-33 P53 Homo sapiens 116-119 10389750-2 1999 The relation between aflatoxin B1 (AFB1 )-related hepatocellular carcinomas (HCCs) and hot spot at codon 249 of the p53 gene has received a great deal of attention, but its significance is still controversial. Aflatoxin B1 35-39 P53 Homo sapiens 116-119 10421546-6 1999 The functional status of p53 in cells was assessed by thymidine and BrdU incorporation following exposure to ionizing radiation (4 Gy). Thymidine 54-63 P53 Homo sapiens 25-28 10391688-0 1999 p53-Dependent growth arrest and altered p53-immunoreactivity following metabolic labelling with 32P ortho-phosphate in human fibroblasts. 32p ortho-phosphate 96-115 P53 Homo sapiens 0-3 10391688-0 1999 p53-Dependent growth arrest and altered p53-immunoreactivity following metabolic labelling with 32P ortho-phosphate in human fibroblasts. 32p ortho-phosphate 96-115 P53 Homo sapiens 40-43 10357771-0 1999 Inverse correlation between p53 protein levels and DNA repair efficiency in human fibroblast strains treated with 4-nitroquinoline 1-oxide: evidence that lesions other than DNA strand breaks trigger the p53 response. 4-Nitroquinoline-1-oxide 114-138 P53 Homo sapiens 28-31 10357771-0 1999 Inverse correlation between p53 protein levels and DNA repair efficiency in human fibroblast strains treated with 4-nitroquinoline 1-oxide: evidence that lesions other than DNA strand breaks trigger the p53 response. 4-Nitroquinoline-1-oxide 114-138 P53 Homo sapiens 203-206 10357771-3 1999 The aim of this study was to identify the triggering signal for induction of p53 in diploid human dermal fibroblasts treated with 4-nitroquinoline 1-oxide (4NQO), a model environmental carcinogen that produces both DNA strand breaks (like ionizing radiation) and alkali-stable bulky DNA lesions (like UV light). 4-Nitroquinoline-1-oxide 130-154 P53 Homo sapiens 77-80 10357771-4 1999 4NQO treatment of fibroblasts cultured from normal and AT donors and those from patients with the UV-hypersensitivity disorder xeroderma pigmentosum (XP, complementation groups A, E and G) resulted in up-regulation of p53 protein. 4-Nitroquinoline-1-oxide 0-4 P53 Homo sapiens 218-221 10357771-7 1999 XP cells with a severe deficiency in the nucleotide excision repair pathway showed abnormally high levels of p53 protein in response to 4NQO treatment, indicating that lesions other than incision-associated DNA strand breaks trigger p53 up-regulation. 4-Nitroquinoline-1-oxide 136-140 P53 Homo sapiens 109-112 10357771-7 1999 XP cells with a severe deficiency in the nucleotide excision repair pathway showed abnormally high levels of p53 protein in response to 4NQO treatment, indicating that lesions other than incision-associated DNA strand breaks trigger p53 up-regulation. 4-Nitroquinoline-1-oxide 136-140 P53 Homo sapiens 233-236 10357771-9 1999 Treatment with 0.12 microM 4NQO, for example, caused a >2-fold up-regulation of p53 in excision repair-deficient (AT, XPA and XPG) strains without eliciting any effect on p53 levels in repair-proficient (normal and XPE) strains. 4-Nitroquinoline-1-oxide 27-31 P53 Homo sapiens 83-86 10357771-9 1999 Treatment with 0.12 microM 4NQO, for example, caused a >2-fold up-regulation of p53 in excision repair-deficient (AT, XPA and XPG) strains without eliciting any effect on p53 levels in repair-proficient (normal and XPE) strains. 4-Nitroquinoline-1-oxide 27-31 P53 Homo sapiens 174-177 10341297-6 1999 Western blot analysis showed that auristatin-PE up-regulated the expression of wt-p53, p21WAF1 and Bax, and down-regulated Bcl-2 and cyclin B in HPAC cells, while only up-regulation of p21WAF1 and Bax was observed in PANC-1 cells. pe 45-47 P53 Homo sapiens 82-85 10394883-2 1999 The incidence of p53 gene abnormalities in human hepatocellular carcinoma (HCC) varies in different geographical areas, being higher in regions where hepatitis virus infection and dietary exposure to aflatoxin B1 are the most common aetiological agents. Aflatoxin B1 200-212 P53 Homo sapiens 17-20 10334204-0 1999 The level of DNA modification by (+)-syn-(11S,12R,13S,14R)- and (-)-anti-(11R,12S,13S,14R)-dihydrodiol epoxides of dibenzo[a,l]pyrene determined the effect on the proteins p53 and p21WAF1 in the human mammary carcinoma cell line MCF-7. (-)-anti-(11r,12s,13s,14r)-dihydrodiol epoxides 64-111 P53 Homo sapiens 172-175 10223459-6 1999 Western immunoblot analysis revealed a marked increase in cellular glial fibrillary acidic protein and wild-type p53 and a decrease in c-myc and c-fos oncoproteins in both cell lines treated with clotrimazole. Clotrimazole 196-208 P53 Homo sapiens 113-116 10206959-18 1999 The down-regulation of hMMP-1 gene expression by endogenous wt-p53 was shown by treatment of U2-OS cells, a wt-p53-containing osteogenic sarcoma line, and Saos-2 cells, a p53-negative osteogenic sarcoma line, with etoposide, a potent inducer of p53 expression. Etoposide 214-223 P53 Homo sapiens 63-66 10206959-19 1999 p53, activated by etoposide, appears to block hMMP-1 promoter activity induced by etoposide in U2-OS cells. Etoposide 18-27 P53 Homo sapiens 0-3 10206959-19 1999 p53, activated by etoposide, appears to block hMMP-1 promoter activity induced by etoposide in U2-OS cells. Etoposide 82-91 P53 Homo sapiens 0-3 10207030-8 1999 Etoposide-induced transactivation was blocked by a dominant negative p53 mutant, indicating that endogenous wild type p53, upon activation by etoposide, transactivated the GPX promoter. Etoposide 0-9 P53 Homo sapiens 118-121 10207030-8 1999 Etoposide-induced transactivation was blocked by a dominant negative p53 mutant, indicating that endogenous wild type p53, upon activation by etoposide, transactivated the GPX promoter. Etoposide 142-151 P53 Homo sapiens 69-72 10207030-8 1999 Etoposide-induced transactivation was blocked by a dominant negative p53 mutant, indicating that endogenous wild type p53, upon activation by etoposide, transactivated the GPX promoter. Etoposide 142-151 P53 Homo sapiens 118-121 10197633-5 1999 Thus, early mitochondria-associated events may play a key role in initiating and/or coordinating tributyrin-mediated growth arrest and apoptosis of wild-type p53 MCF-7 cells. tributyrin 97-107 P53 Homo sapiens 158-161 10374839-3 1999 In vitro experiments using human cell line cells and aflatoxin B1 have demonstrated the induction of p53 mutations in codon 249 and adjacent codons. Aflatoxin B1 53-65 P53 Homo sapiens 101-104 10374839-6 1999 In an in vivo rodent model systems using the aflatoxin B1-sensitive male F344 rat, previous studies have shown that hepatocarcinogenesis is accompanied by significant incidences of codon 12 mutations in K-ras and codon 13 mutations in N-ras genes, but in contrast to the human, apparently not by mutations in codon 243 of the p53 gene (which corresponds to codon 249 in the human gene). Aflatoxin B1 45-57 P53 Homo sapiens 326-329 10037186-4 1999 Suppression of c-myc using antisense oligodeoxynucleotides (in the absence of p53) was sufficient to trigger apoptosis in Tu-138 cells, raising the possibility that the reduction of c-myc may be involved in at least one of the cell death pathways mediated by p53. Oligodeoxyribonucleotides 37-58 P53 Homo sapiens 259-262 9880547-8 1999 These findings suggest a role for mitogen-activated protein kinase in the degradation of the DNA binding-impaired form of p53 protein and in the bryostatin-induced differentiation observed in this cell line. Bryostatins 145-155 P53 Homo sapiens 122-125 9927204-5 1999 Clonogenic survival assays revealed that cells overexpressing the p53His175 mutant, but not the p53His273 mutant, recover preferentially from etoposide treatment. Etoposide 142-151 P53 Homo sapiens 66-69 9927204-6 1999 Moreover, p53His175 as well as p53His179 reduced substantially the rate of etoposide-induced apoptosis, whereas p53His273 and p53Trp248 had a much milder protective effect. Etoposide 75-84 P53 Homo sapiens 10-13 10667218-6 1999 This finding indicates that TSA activates the p21/WAF1/Cip1 promoter through the Sp1 sites in a p53-independent manner. trichostatin A 28-31 P53 Homo sapiens 96-99 10368806-9 1999 Furthermore, cells treated with genistein showed an increased expression of endogenous wild-type p53, while the level of the mutant p53 protein remained unchanged. Genistein 32-41 P53 Homo sapiens 97-100 10368806-10 1999 From these results, we conclude that genistein induces apoptosis in NSCLC cells through a p53-independent pathway and, thus, may act as an anticancer agent. Genistein 37-46 P53 Homo sapiens 90-93 9769393-6 1998 On the other hand, an A to G substitution at codon 170 in exon 5 of p53 gene resulting in glutamic acid (ACG) to glycine (GCG) was detected in the DNA of her tongue cancer. acceleratory factor from growth hormone 105-108 P53 Homo sapiens 68-71 9788435-3 1998 The effect of induced p53 and p21waf1 expression on the cytotoxic action of the anti-cancer drugs etoposide and cisplatin was also analysed. Etoposide 98-107 P53 Homo sapiens 22-25 9770348-11 1998 An inhibitor of transcription, alpha-amanitin, dramatically induced wt p53 protein, whereas Mdm-2 protein was downregulated. Alpha-Amanitin 31-45 P53 Homo sapiens 71-74 9766444-6 1998 The differentiation response to transfected p53 with or without INF-gamma was inhibited by cyclic adenosine monophosphate (cAMP)-inducing agents (dibutyryl cyclic adenosine 3":5"-monophosphate, forskolin, and 3-isobutyl-1-methylxanthine) in a dose-dependent manner. 1-Methyl-3-isobutylxanthine 209-236 P53 Homo sapiens 44-47 9690517-5 1998 Here we report that the induction of p21 by DZQ is regulated at the transcriptional level, and requires the activation of p53, a tumor suppressor protein. ethylenimine quinone 44-47 P53 Homo sapiens 122-125 9690517-6 1998 In cells that lack functional p53 protein, DZQ-mediated p21 induction is greatly diminished. ethylenimine quinone 43-46 P53 Homo sapiens 30-33 9690517-7 1998 However, the introduction of a wild type p53 gene into p53-negative cells restores the strong DZQ-inducibility of p21. ethylenimine quinone 94-97 P53 Homo sapiens 41-44 9690517-7 1998 However, the introduction of a wild type p53 gene into p53-negative cells restores the strong DZQ-inducibility of p21. ethylenimine quinone 94-97 P53 Homo sapiens 55-58 9674709-0 1998 Superinduction of wild-type p53 protein after 2-methoxyestradiol treatment of Ad5p53-transduced cells induces tumor cell apoptosis. 2-Methoxyestradiol 46-64 P53 Homo sapiens 28-31 9674709-1 1998 Because 2-methoxyestradiol (2-MeOE2) induces and stabilizes wild-type p53 protein (wt p53) in human lung cancer cell lines posttranscriptionally, we sought to study its effects on Ad5p53-transduced lung cancer cell lines at a low multiplicity of infection (1 MOI). 2-Methoxyestradiol 8-26 P53 Homo sapiens 70-73 9674709-1 1998 Because 2-methoxyestradiol (2-MeOE2) induces and stabilizes wild-type p53 protein (wt p53) in human lung cancer cell lines posttranscriptionally, we sought to study its effects on Ad5p53-transduced lung cancer cell lines at a low multiplicity of infection (1 MOI). 2-Methoxyestradiol 8-26 P53 Homo sapiens 86-89 9674709-1 1998 Because 2-methoxyestradiol (2-MeOE2) induces and stabilizes wild-type p53 protein (wt p53) in human lung cancer cell lines posttranscriptionally, we sought to study its effects on Ad5p53-transduced lung cancer cell lines at a low multiplicity of infection (1 MOI). 2-Methoxyestradiol 28-35 P53 Homo sapiens 70-73 9674709-1 1998 Because 2-methoxyestradiol (2-MeOE2) induces and stabilizes wild-type p53 protein (wt p53) in human lung cancer cell lines posttranscriptionally, we sought to study its effects on Ad5p53-transduced lung cancer cell lines at a low multiplicity of infection (1 MOI). 2-Methoxyestradiol 28-35 P53 Homo sapiens 86-89 9674709-2 1998 Treating these cells with 2-MeOE2 resulted in superinduction of wt p53 protein expression followed by apoptosis, as shown by terminal deoxynucleotidyl transferase (TdT) staining, and upregulation of wt p53 expression, as shown by Western blot analysis. 2-Methoxyestradiol 26-33 P53 Homo sapiens 67-70 9674709-2 1998 Treating these cells with 2-MeOE2 resulted in superinduction of wt p53 protein expression followed by apoptosis, as shown by terminal deoxynucleotidyl transferase (TdT) staining, and upregulation of wt p53 expression, as shown by Western blot analysis. 2-Methoxyestradiol 26-33 P53 Homo sapiens 202-205 9665463-3 1998 Phorbol ester induced p21WAF1 expression, which was maximal at 4 to 8 h with reduction back to baseline by 24 to 48 h. In contrast, increasing the extracellular Ca2+ concentration from 70 micromol/L to 1.5 mmol/L resulted in upregulation of p21WAF1 expression with a slower time course, with peak induction at 18 to 24 h. No parallel increase in p53 expression was observed in normal human keratinocytes. Phorbol Esters 0-13 P53 Homo sapiens 346-349 9665463-4 1998 Up-regulation of p21WAF1 was also observed in response to phorbol ester in HaCaT cells, which carry homozygous and inactivating mutations for p53. Phorbol Esters 58-71 P53 Homo sapiens 142-145 9665463-6 1998 The results demonstrate a differential time course of p21WAF1 protein up-regulation in response to phorbol ester and Ca2+, signals that result in keratinocyte differentiation, and suggest that induction of p21WAF1 in differentiating human keratinocytes occurs through protein kinase C-dependent and p53-independent mechanisms. Phorbol Esters 99-112 P53 Homo sapiens 299-302 9650599-3 1998 The presence of the p53-expressing vector was toxic in both cell lines compared to control cells or to those containing the beta-gal vector. beta-D-galactose 124-132 P53 Homo sapiens 20-23 10076525-0 1998 Effects of perturbations of pools of deoxyribonucleoside triphosphates on expression of ribonucleotide reductase, a G1/S transition state enzyme, in p53-mutated cells. deoxyribonucleoside triphosphates 37-70 P53 Homo sapiens 149-152 10076525-9 1998 This suggests that in the presence of antimetabolite-induced depletion of dNTPs, SW480 cells, which lack a normal p53 gene, will proceed into S phase, and that this is associated with a rise in expression of the G1/S transition state enzyme, RR. dntps 74-79 P53 Homo sapiens 114-117 9607592-3 1998 The sensitization ratio due to the transfected wt p53 varied from about 2-fold for cisplatin to over 50-fold for thymidine. Thymidine 113-122 P53 Homo sapiens 50-53 9548807-10 1998 Thiotepa, a non-quinone aziridine-containing agent, and 1,4-benzoquinone (p-BQ), a redox cycling quinone, increased p53 levels. 1,3,4,6,7,11b-hexahydro-9,10-dimethoxy-2H-benzo(a)quinolizine-2-spiro-3'-(1'-phenyl)succinimide 74-78 P53 Homo sapiens 116-119 9513045-6 1998 The similar effects of genistein on a number of breast carcinoma cell lines with different ER and p53 status suggest that the actions of genistein reported here are mediated through ER and p53 independent mechanisms. Genistein 137-146 P53 Homo sapiens 98-101 9513045-6 1998 The similar effects of genistein on a number of breast carcinoma cell lines with different ER and p53 status suggest that the actions of genistein reported here are mediated through ER and p53 independent mechanisms. Genistein 137-146 P53 Homo sapiens 189-192 9648155-1 1998 Abnormalities of the p53 tumor suppressor gene were investigated in 22 foci from 14 adenoid cystic carcinomas (ACC) by polymerase chain reaction (PCR)-based assays for dinucleotide (CA)n and pentanucleotide (AAAAT)n repeat polymorphisms and by immunohistochemical staining for oncoprotein expression. Dinucleoside Phosphates 168-180 P53 Homo sapiens 21-24 9648155-1 1998 Abnormalities of the p53 tumor suppressor gene were investigated in 22 foci from 14 adenoid cystic carcinomas (ACC) by polymerase chain reaction (PCR)-based assays for dinucleotide (CA)n and pentanucleotide (AAAAT)n repeat polymorphisms and by immunohistochemical staining for oncoprotein expression. pentanucleotide 191-206 P53 Homo sapiens 21-24 9546425-1 1998 Using UvrABC incision in combination with ligation-mediated PCR (LMPCR) we have previously shown that benzo(a)pyrene diol epoxide (BPDE) adduct formation along the nontranscribed strand of the human p53 gene is highly selective; the preferential binding sites coincide with the major mutation hotspots found in human lung cancers. lmpcr 65-70 P53 Homo sapiens 199-202 9719502-4 1998 In addition, p53 protein overexpression was assessed by immunohistochemistry using the monoclonal antibody DO-7 on paraffin-embedded tissue sections. do-7 107-111 P53 Homo sapiens 13-16 9398050-6 1997 LN-229 cells which have partial p53-wild-type activity show enhanced expression of p53, p21 and bax protein, whereas bcl-2 levels decrease, after exposure to camptothecin. Camptothecin 158-170 P53 Homo sapiens 32-35 9494534-8 1997 Levels of p53 mRNA decreased with increasing resistance to vindesine, etoposide and fotemustine. Etoposide 70-79 P53 Homo sapiens 10-13 9264376-0 1997 Camptothecin-induced apoptosis in p53-null human leukemia HL60 cells and their isolated nuclei: effects of the protease inhibitors Z-VAD-fmk and dichloroisocoumarin suggest an involvement of both caspases and serine proteases. Camptothecin 0-12 P53 Homo sapiens 34-37 9257692-7 1997 In this study I show that compounds that allow the accumulation of DNA single strand breaks, ara c and hydroxyurea, enhanced the UVC radiation (254 nm)-dependent increase in p53, but had no effect on the solar UV radiation-dependent increase. Hydroxyurea 103-114 P53 Homo sapiens 174-177 9199206-4 1997 A region of the p53 promoter (from -199 to +142) containing 15 CpG dinucleotides was placed in a pCAT reporter plasmid and reporter activity was assessed in host CV-1 cells. Dinucleoside Phosphates 67-80 P53 Homo sapiens 16-19 9203947-6 1997 Intranuclear p53 protein was immunostained by the avidin-biotin complex method. avidin-biotin 50-63 P53 Homo sapiens 13-16 9168435-7 1997 DTctGMCSF also efficiently killed AML cells deficient in p53 expression, as well as radiation-resistant AML cells and mixed lineage leukemia cells expressing high levels of bcl-2. dtctgmcsf 0-9 P53 Homo sapiens 57-60 21590066-4 1997 Although allelic imbalance in the p53 and DCC genes were observed in ten out of eleven primary tumors and all liver metastases using a dinucleotide repeat polymorphism, mutation was not detected in the DNA polymerase beta mRNA. Dinucleoside Phosphates 135-147 P53 Homo sapiens 34-37 9332498-5 1997 These experiments demonstrated a decreased PAb 240 (mutant-specific) reactivity of nuclear p53(273.His) in EGF-treated cells, while that of PAb 1620 (wild-type specific) was enhanced. 4-Aminobenzoic Acid 43-46 P53 Homo sapiens 91-94 21533392-8 1997 Moreover, in the presence of okadaic acid, a potent inhibitor of protein phosphatase PP2a, phosphorylation of p53 is detectable early in G(1)-phase of the cell cycle. Okadaic Acid 29-41 P53 Homo sapiens 110-113 9018125-1 1997 2-Methoxyestradiol (2-MeOE2) treatment caused significant growth inhibition of H460 and A549 human lung cancer cell lines which contain wild-type p53. 2-Methoxyestradiol 0-18 P53 Homo sapiens 146-149 9018125-1 1997 2-Methoxyestradiol (2-MeOE2) treatment caused significant growth inhibition of H460 and A549 human lung cancer cell lines which contain wild-type p53. 2-Methoxyestradiol 20-27 P53 Homo sapiens 146-149 9018125-3 1997 Western blot analysis indicated that 2-MeOE2 treatment resulted in an eightfold increase in the endogenous wild-type p53 protein, while the level of the mutant p53 protein remained unchanged. 2-Methoxyestradiol 37-44 P53 Homo sapiens 117-120 9018125-4 1997 TdT staining indicated that following 2-MeOE2-mediated increases in wildtype p53 protein, cells bypass the G1-S checkpoint of the cell cycle with 30 to 40% undergoing apoptosis. 2-Methoxyestradiol 38-45 P53 Homo sapiens 77-80 9018125-5 1997 Introduction of anti-sense wt-p53 into wt-p53 cells abrogated the 2-MeOE2 effect. 2-Methoxyestradiol 66-73 P53 Homo sapiens 30-33 9018125-5 1997 Introduction of anti-sense wt-p53 into wt-p53 cells abrogated the 2-MeOE2 effect. 2-Methoxyestradiol 66-73 P53 Homo sapiens 42-45 9018125-6 1997 A significant portion of lung cancer retains the wild-type p53 gene therefore, 2-MeOE2 may have therapeutic application. 2-Methoxyestradiol 79-86 P53 Homo sapiens 59-62 9184169-5 1997 Further support for this observation came from the stable transfection studies in which p53 transfectants expressing high levels of wild-type p53 became resistant to genistein. Genistein 166-175 P53 Homo sapiens 88-91 9184169-5 1997 Further support for this observation came from the stable transfection studies in which p53 transfectants expressing high levels of wild-type p53 became resistant to genistein. Genistein 166-175 P53 Homo sapiens 142-145 9329647-0 1997 Mutations, tissue accumulations, and serum levels of p53 in patients with occupational cancers from asbestos and silica exposure. Silicon Dioxide 113-119 P53 Homo sapiens 53-56 9816160-8 1996 Conversely, the hazard increased with the increase of p53-positive cells only for tumors with a [3H]dT LI lower than 7.5%. Thymidine 100-102 P53 Homo sapiens 54-57 8912651-8 1996 Western blot showed that wild-type p53 protein was unchanged after MCF-7 cells had been exposed to 50 microM 3,3"-diindolylmethane for 8 h. This study provides evidences that 3,3"-diindolylmethane induces apoptosis in human cancer cells and that the induction of apoptosis is independent of p53 pathway. 3,3'-diindolylmethane 109-130 P53 Homo sapiens 35-38 8912651-8 1996 Western blot showed that wild-type p53 protein was unchanged after MCF-7 cells had been exposed to 50 microM 3,3"-diindolylmethane for 8 h. This study provides evidences that 3,3"-diindolylmethane induces apoptosis in human cancer cells and that the induction of apoptosis is independent of p53 pathway. 3,3'-diindolylmethane 109-130 P53 Homo sapiens 291-294 8912651-8 1996 Western blot showed that wild-type p53 protein was unchanged after MCF-7 cells had been exposed to 50 microM 3,3"-diindolylmethane for 8 h. This study provides evidences that 3,3"-diindolylmethane induces apoptosis in human cancer cells and that the induction of apoptosis is independent of p53 pathway. 3,3'-diindolylmethane 175-196 P53 Homo sapiens 35-38 8912651-8 1996 Western blot showed that wild-type p53 protein was unchanged after MCF-7 cells had been exposed to 50 microM 3,3"-diindolylmethane for 8 h. This study provides evidences that 3,3"-diindolylmethane induces apoptosis in human cancer cells and that the induction of apoptosis is independent of p53 pathway. 3,3'-diindolylmethane 175-196 P53 Homo sapiens 291-294 8912537-5 1996 Immunohistochemical expression of p53 was investigated using a monoclonal anti-p53 antibody (DO-7). do-7 93-97 P53 Homo sapiens 34-37 8912537-5 1996 Immunohistochemical expression of p53 was investigated using a monoclonal anti-p53 antibody (DO-7). do-7 93-97 P53 Homo sapiens 79-82 8950479-5 1996 In vitro studies with a bladder carcinoma cell line containing a wild type p53 showed that it underwent a G1 checkpoint after etoposide, potentially allowing DNA damage repair, as well as apoptosis. Etoposide 126-135 P53 Homo sapiens 75-78 8704210-8 1996 To analyze the possible interaction of FAC with the p53 pathway, we analyzed p53 induction in mock and corrected cell lines following exposure to MMC.

Camptothecin 163-175 P53 Homo sapiens 52-55 8806433-2 1996 HL60 cells are p53 null and extremely sensitive to a variety of apoptotic stimuli including DNA damage induced by the topoisomerase I inhibitor, camptothecin. Camptothecin 145-157 P53 Homo sapiens 15-18 8707413-8 1996 Ad-p53-infected SKBr3 breast cancer cells were more sensitive to cytotoxicity of the DNA damaging drugs mitomycin C or Adriamycin, but not the M-phase specific drug vincristine. Mitomycin 104-115 P53 Homo sapiens 3-6 8707413-9 1996 Our results suggest that Ad-p53 is capable of infecting and killing cancer cells of diverse tissue origins (including multi-drug resistant cancer cells), that p21WAFI/CIPI may be a useful marker of p53 infectivity and that there may be synergy between Ad-p53 and either mitomycin C or Adriamycin induced cell death in tumors with p53 mutations. Mitomycin 270-281 P53 Homo sapiens 28-31 8651706-8 1996 Phosphatase digestion of immunoprecipitated p53 effectively removed phosphorous groups from the recombinant protein, reducing the number of isoforms from 11 to 2, demonstrating that phosphorylation is the major posttranslational event in the recombinant protein. Phosphinidene 68-79 P53 Homo sapiens 44-47 8639538-1 1996 The tumor suppressor protein p53 plays a central role in the cellular response to genotoxic lesions and has been shown to be activated by most anticancer agents such as mitomycin C. Mitomycin 169-180 P53 Homo sapiens 29-32 8639538-5 1996 In vitro experiments with purified recombinant proteins show that p53 increases the catalytic activities of topoisomerase I as measured by relaxation of supercoiled DNA, stabilization of the covalent topoisomerase I-DNA complex (in the presence of camptothecin), and phosphorylation of SR protein splicing factor ASF/SF2. Camptothecin 248-260 P53 Homo sapiens 66-69 8640905-2 1996 The most frequent mutation in HCC in populations exposed to a high dietary intake of aflatoxin B1 (AFB1) is an AGGarg-->AGTser missense mutation in codon 249 of the p53 gene. Aflatoxin B1 85-97 P53 Homo sapiens 168-171 8634092-9 1996 The frequency of BPD-induced lesions in the p53 gene was sixfold to sevenfold greater than in the beta-globin gene and 200- to 300-fold greater than in bulk DNA. benzo(a)pyrene 7,8-dihydrodiol 17-20 P53 Homo sapiens 44-47 9387565-2 1996 p53 protein was identified in all 17 cases (100%) of OCL, and 78% in control cases. ocl 53-56 P53 Homo sapiens 0-3 8620501-0 1996 Hypersensitivity of human testicular tumors to etoposide-induced apoptosis is associated with functional p53 and a high Bax:Bcl-2 ratio. Etoposide 47-56 P53 Homo sapiens 105-108 8620501-8 1996 First, they have functional p53: the product of the p53-dependent gene waf-1 was increased after etoposide treatment. Etoposide 97-106 P53 Homo sapiens 28-31 8620501-8 1996 First, they have functional p53: the product of the p53-dependent gene waf-1 was increased after etoposide treatment. Etoposide 97-106 P53 Homo sapiens 52-55 8608941-3 1996 However, we found that certain ribonucleotide biosynthesis inhibitors caused a p53-dependent G0 or early G1 arrest in the absence of replicative DNA synthesis or detectable DNA damage in normal human fibroblasts. Ribonucleotides 31-45 P53 Homo sapiens 79-82 8829621-3 1996 On the other hand, significant induction of p53 message was demonstrated when Hela cells were exposed to genistein, a protein tyrosine kinase inhibitor. Genistein 105-114 P53 Homo sapiens 44-47 8599578-0 1996 Diethylstilbestrol-induced immortalization of human endometrial cells: alterations in p53 and estrogen receptor. Diethylstilbestrol 0-18 P53 Homo sapiens 86-89 8779543-1 1996 Mutations of the p53 tumour-suppressor gene in human hepatocellular carcinomas from certain geographic areas appear to be associated with high dietary exposure to aflatoxin B1 (AFB1). Aflatoxin B1 163-175 P53 Homo sapiens 17-20 8779543-1 1996 Mutations of the p53 tumour-suppressor gene in human hepatocellular carcinomas from certain geographic areas appear to be associated with high dietary exposure to aflatoxin B1 (AFB1).

Camptothecin 115-127 P53 Homo sapiens 161-164 8979269-6 1996 A253-p53 cells could be distinguished from native A253 cells by prolonged doubling times (2-5 fold) and by a marked reduction of [3H]-thymidine uptake. Thymidine 134-143 P53 Homo sapiens 5-8 8562479-3 1995 Flow cytometry, growth, and cytochemical analysis for alpha-napthyl butyrate esterase activity and nitroblue tetrazolium reduction indicated that wild-type p53 but not mutant p53 induced early monocytic differentiation in the transfected HL60 cells without terminal growth arrest. Tetrazolium Salts 109-120 P53 Homo sapiens 156-159 8562479-5 1995 HL60 cells transfected with wild-type p53 were more sensitive to stress, such as growth in serum-depleted medium and exposure to a chemotherapeutic agent, etoposide. Etoposide 155-164 P53 Homo sapiens 38-41 7563393-0 1995 Prognostic value of p53 nuclear overexpression in patients with invasive bladder cancer treated with neoadjuvant MVAC. M-VAC protocol 113-117 P53 Homo sapiens 20-23 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Mitomycin 95-104 P53 Homo sapiens 151-154 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Mitomycin 95-104 P53 Homo sapiens 174-177 7623839-2 1995 We show that exposure of cells to various genotoxic agents, including anticancer drugs such as mitomycin and 5-fluorouracil, results in an increase in p53 mRNA levels and in p53 promoter activation, indicating that the p53 genotoxic stress response is partly regulated at the transcriptional level. Mitomycin 95-104 P53 Homo sapiens 174-177 7750085-1 1995 Anticancer drugs etoposide and mitomycin C increased nuclear p53 protein and decreased proliferating cell nuclear antigen (PCNA) of PLC/PRF/5 human hepatoma cells. Etoposide 17-26 P53 Homo sapiens 61-64 7750085-1 1995 Anticancer drugs etoposide and mitomycin C increased nuclear p53 protein and decreased proliferating cell nuclear antigen (PCNA) of PLC/PRF/5 human hepatoma cells. Mitomycin 31-42 P53 Homo sapiens 61-64 7636632-7 1995 Moreover, mutations are targeted at py-py sequences in over 90% of skin tumors whereas in internal cancers the distribution is proportional to the frequency of bipyrimidine sequences in the p53 gene. 2,2'-Bipyrimidine 160-172 P53 Homo sapiens 190-193 7537340-1 1995 We previously described the use of a phage-displayed library of random hexapeptides to define and localise the epitope on the human tumor suppressor protein p53 recognised by the monoclonal antibody PAb240. pab240 199-205 P53 Homo sapiens 157-160 7627557-2 1995 We have examined potential p53-mediated effects of metabolically labeling cultured mammalian cells with [35S]methionine and [3H]thymidine, methods that are commonly used to study the biochemical properties, synthesis, processing and degradation of proteins and the replication of DNA in proliferating cells. Thymidine 128-137 P53 Homo sapiens 27-30 7790147-0 1995 Effect of orally administered antithyroid thioureylenes on PCNA and P53 expression in psoriatic lesions. thioureylenes 42-55 P53 Homo sapiens 68-71 7854378-8 1995 Furthermore, 100 percent of the mutations in the patients who neither drank nor smoked occurred at sites containing cytidine phosphate guanosine dinucleotides (potentially representing endogenous mutations) within the p53 gene (5 of 5 mutations; 95 percent confidence interval, 48 to 100 percent), whereas only 23 percent of those in cigarette smokers consisted of such changes (12 of 53 mutations; 95 percent confidence interval, 12 to 36 percent; P = 0.001). cytidine phosphate guanosine dinucleotides 116-158 P53 Homo sapiens 218-221 7896881-4 1995 Upon introduction of temperature-sensitive p53 into HC11 cells, which lack wild-type (wt) p53, PCD was observed after mitomycin treatment at 32 degrees, when the ts p53 protein is in wt conformation. Mitomycin 118-127 P53 Homo sapiens 43-46 7896881-5 1995 Thus, wt p53 mediates activation of PCD in response to mitomycin in HC11 cells. Mitomycin 55-64 P53 Homo sapiens 9-12 7835585-6 1995 Intranuclear p53 protein was immunostained by the avidin-biotin complex method. avidin-biotin 50-63 P53 Homo sapiens 13-16 7824283-7 1995 Moreover, the same impairment in p53 induction is observed after exposure to mitomycin C, a chemical agent for which FA cells demonstrate a specific cellular and chromosomal hypersensitivity, as well as after u.v.-B irradiation, an agent known to cause oxidative stress. Mitomycin 77-88 P53 Homo sapiens 33-36 7819056-5 1995 Sequencing analysis of the entire coding region of the p53 gene revealed that both alleles were expressed in the JEG-3 cell line, and one of the alleles contained a point mutation (G to T) in codon 167 (Gln to His). Glutamine 203-206 P53 Homo sapiens 55-58 7718488-3 1995 Expression of p53 protein was characterized by biosynthetic labeling and immunoprecipitation with the monoclonal antibodies pAb 1801 (reacting with wild-type and mutant human p53), pAb 240 (reacting with mutant human p53) and pAb 1620 (reacting with wild-type human p53). 4-Aminobenzoic Acid 124-127 P53 Homo sapiens 14-17 7718488-3 1995 Expression of p53 protein was characterized by biosynthetic labeling and immunoprecipitation with the monoclonal antibodies pAb 1801 (reacting with wild-type and mutant human p53), pAb 240 (reacting with mutant human p53) and pAb 1620 (reacting with wild-type human p53). 4-Aminobenzoic Acid 181-184 P53 Homo sapiens 14-17 7718488-3 1995 Expression of p53 protein was characterized by biosynthetic labeling and immunoprecipitation with the monoclonal antibodies pAb 1801 (reacting with wild-type and mutant human p53), pAb 240 (reacting with mutant human p53) and pAb 1620 (reacting with wild-type human p53). 4-Aminobenzoic Acid 181-184 P53 Homo sapiens 14-17 7655736-6 1995 Additional immunostaining of the positive samples with mutant p53-specific Pab240 monoclonal antibody failed to detect immunopositive material. pab240 75-81 P53 Homo sapiens 62-65 7713039-3 1994 This hypothesis has been supported by genetic evidence in liver tumors which has associated aflatoxin B1 exposure with the detection of inactivating DNA mutations within the human p53 tumor suppressor gene. Aflatoxin B1 92-104 P53 Homo sapiens 180-183 7954409-1 1994 The present study assessed the role of the p53 tumor suppressor gene in cell cycle arrest and apoptosis following treatment of Burkitt"s lymphoma and lymphoblastoid cell lines with gamma-rays, etoposide, nitrogen mustard, and cisplatin. Etoposide 193-202 P53 Homo sapiens 43-46 7954409-3 1994 We found that gamma-rays and etoposide induced a strong G1 arrest in the wild-type p53 lines while nitrogen mustard and cisplatin induced relatively little G1 arrest. Etoposide 29-38 P53 Homo sapiens 83-86 7954409-5 1994 The degree of G1 arrest observed with these agents correlated with the rate of p53 and p21Waf1/Cip1 protein accumulation: gamma-rays and etoposide induced rapid accumulation of both p53 and p21Waf1/Cip1; nitrogen mustard and cisplatin induced slow accumulation of p53 and no major accumulation of the p21Waf1/Cip1 protein. Etoposide 137-146 P53 Homo sapiens 79-82 7954409-5 1994 The degree of G1 arrest observed with these agents correlated with the rate of p53 and p21Waf1/Cip1 protein accumulation: gamma-rays and etoposide induced rapid accumulation of both p53 and p21Waf1/Cip1; nitrogen mustard and cisplatin induced slow accumulation of p53 and no major accumulation of the p21Waf1/Cip1 protein. Etoposide 137-146 P53 Homo sapiens 182-185 7954409-5 1994 The degree of G1 arrest observed with these agents correlated with the rate of p53 and p21Waf1/Cip1 protein accumulation: gamma-rays and etoposide induced rapid accumulation of both p53 and p21Waf1/Cip1; nitrogen mustard and cisplatin induced slow accumulation of p53 and no major accumulation of the p21Waf1/Cip1 protein. Etoposide 137-146 P53 Homo sapiens 182-185 7954409-8 1994 We also observed an inverse sensitivity relationship between nitrogen mustard/cisplatin and etoposide in the mutant p53 lines and this was found to correlate with topoisomerase II mRNA levels in the cells. Etoposide 92-101 P53 Homo sapiens 116-119 7955036-2 1994 Our hypothesis is that lung cancers from MG workers contain mutations (G:C to A:T transitions) as the result of MG-produced DNA promutagenic adducts in the p53 tumor suppressor gene. Mustard Gas 41-43 P53 Homo sapiens 156-159 7955036-9 1994 The p53 mutational frequency in the MG-exposed cases is similar to the non-exposed controls and the usual smoking-related lung cancers reported previously. Mustard Gas 36-38 P53 Homo sapiens 4-7 8084582-9 1994 Inhibition of transcription with alpha-amanitin evokes nuclear accumulation of p53 both in normal cells and in XP cells. Alpha-Amanitin 33-47 P53 Homo sapiens 79-82 8044794-0 1994 Hyperphosphorylation of p53 induced by okadaic acid attenuates its transcriptional activation function. Okadaic Acid 39-51 P53 Homo sapiens 24-27 8044794-4 1994 Incubation of the transfected cells with okadaic acid, an inhibitor of serine phosphatases 2A and 1, induced hyperphosphorylation of p53 protein. Okadaic Acid 41-53 P53 Homo sapiens 133-136 8044794-9 1994 These results suggest that the phosphorylation induced by okadaic acid may selectively modulate the transcription activation function of p53. Okadaic Acid 58-70 P53 Homo sapiens 137-140 8207805-9 1994 In the ACH-2 cell line, which is now demonstrated to contain an endogenous mutant form of p53 (amino acid 248, Arg to Gln), additional mutant p53 proteins did not alter HIV-1 replication. Glutamine 118-121 P53 Homo sapiens 90-93 8275497-1 1994 We investigated the expression of p53 in paraformaldehyde-lysine-periodate fixed normal and chronic myelogenous leukemia (CML) hemopoietic cells with flow cytometry and two monoclonal antibodies, PAb1801 and the mutant-conformation-associated PAb240. paraform 41-57 P53 Homo sapiens 34-37 8275497-1 1994 We investigated the expression of p53 in paraformaldehyde-lysine-periodate fixed normal and chronic myelogenous leukemia (CML) hemopoietic cells with flow cytometry and two monoclonal antibodies, PAb1801 and the mutant-conformation-associated PAb240. metaperiodate 65-74 P53 Homo sapiens 34-37 8275497-1 1994 We investigated the expression of p53 in paraformaldehyde-lysine-periodate fixed normal and chronic myelogenous leukemia (CML) hemopoietic cells with flow cytometry and two monoclonal antibodies, PAb1801 and the mutant-conformation-associated PAb240. pab240 243-249 P53 Homo sapiens 34-37 8275497-3 1994 The expression of a p53 protein reactive with PAb240 was closely associated with CD34+/HLA-DR+ cells and with cells in active cell cycle, while the p53 protein recognized by PAb1801 was mainly found in CD34+/HLA-DR- cells and in cells in the G0/G1 phases of the cell cycle. pab240 46-52 P53 Homo sapiens 20-23 8280176-0 1993 Okadaic acid inhibits dephosphorylation of cytoplasmic p53 during lymphocyte activation. Okadaic Acid 0-12 P53 Homo sapiens 55-58 8280176-3 1993 Treatments of T cells with okadaic acid (1nM) prior to addition of Concanavalin-A/serum inhibited completely the dephosphorylation of cytosolic p53 observed to occur within 10-20min of stimulation. Okadaic Acid 27-39 P53 Homo sapiens 144-147 8217600-6 1993 The remaining 31 samples expressed p53 detected by PAb240 which recognises mutant p53 and is predicted to recognise wild-type p53 in the promoter conformation. pab240 51-57 P53 Homo sapiens 35-38 8217600-6 1993 The remaining 31 samples expressed p53 detected by PAb240 which recognises mutant p53 and is predicted to recognise wild-type p53 in the promoter conformation. pab240 51-57 P53 Homo sapiens 82-85 8217600-6 1993 The remaining 31 samples expressed p53 detected by PAb240 which recognises mutant p53 and is predicted to recognise wild-type p53 in the promoter conformation. pab240 51-57 P53 Homo sapiens 82-85 8096551-2 1993 Most of the mutations were G to T transversions in codon 249 of the p53 gene in HCCs in China and Mozambique, where aflatoxin B1 was a risk factor. Aflatoxin B1 116-128 P53 Homo sapiens 68-71 8418091-14 1993 PAb240 may be a useful tool not only in screening point mutations of the p53 gene in osteosarcomas but also in the differential diagnosis between osteosarcomas and reactive bone-forming lesions. pab240 0-6 P53 Homo sapiens 73-76 8380918-11 1993 Less frequent than the deamination of 5-methyl cytosine in CpG dinucleotides, mutations resulting in loss or gain of nucleotide base pairs may represent the second highest endogenous mutagenic event for p53 gene in human cancers. Dinucleoside Phosphates 63-76 P53 Homo sapiens 203-206 1330291-1 1992 In order to clarify the significance of mutation of the p53 tumor suppressor gene in the genesis and development of human hepatocellular carcinoma (HCC) in an aflatoxin B1 low-exposure area, the spectrum, i.e., incidence, type, and site, of p53 gene mutations was examined in 169 tissue samples resected mainly from Japanese patients using single-strand conformation polymorphism analysis and direct sequencing. Aflatoxin B1 159-171 P53 Homo sapiens 56-59 1358781-3 1992 Immunoreactive p53 was observed in the nuclei of tumor cells in 4% paraformaldehyde-fixed, frozen sections (12 of 15) and paraffin-embedded sections (11 of 15), but not in routinely processed (10% formalin-fixed) specimens. paraform 67-83 P53 Homo sapiens 15-18 1406679-5 1992 Phosphorylation of the conserved serine 15 in human p53 peptides depended on the presence of an adjacent glutamine, and phosphorylation was inhibited by the presence of a nearby lysine. Glutamine 105-114 P53 Homo sapiens 52-55 1644930-6 1992 The other nonhereditary p53 mutation was a transition at codon 248 (CGG to CAG, arginine to glutamine) found in the lymphoblasts of a patient with a preleukemic syndrome and acute lymphoblastic leukemia (ALL) whose brother is a long-term survivor of ALL. Glutamine 92-101 P53 Homo sapiens 24-27 1685017-1 1991 p53 expression was studied in 111 primary breast cancers with a monoclonal antibody (PAb240) that reacts with an epitope in mutant p53. pab240 85-91 P53 Homo sapiens 0-3 1685017-1 1991 p53 expression was studied in 111 primary breast cancers with a monoclonal antibody (PAb240) that reacts with an epitope in mutant p53. pab240 85-91 P53 Homo sapiens 131-134 1958596-3 1991 One sample [human colon cancer (HCC) 278] was found to have a TP53 mutation altering the amino acid glutamine 167 in exon 5. Glutamine 100-109 P53 Homo sapiens 62-66 1691710-5 1990 We have developed a monoclonal antibody to p53 designated PAb240 which does not immunoprecipitate wild type p53. pab240 58-64 P53 Homo sapiens 43-46 1691710-6 1990 A series of different p53 mutants all react more strongly with PAb240 than with PAb246. pab240 63-69 P53 Homo sapiens 22-25 1691710-7 1990 The PAb240 reactive form of p53 cannot bind to SV40 large T antigen but does bind to HSP70. pab240 4-10 P53 Homo sapiens 28-31 1691710-9 1990 PAb240 recognizes all forms of p53 when they are denatured. pab240 0-6 P53 Homo sapiens 31-34 1691710-11 1990 We propose that immunoprecipitation of p53 by PAb240 is diagnostic of mutation in both murine and human systems and suggest that the different point mutations which convert p53 from a recessive to a dominant oncogene exert a common conformational effect on the protein. pab240 46-52 P53 Homo sapiens 173-176 33591325-6 2021 Serial molecular profiling revealed that clearance of TP53 mutations during HMA therapy was associated with superior OS (HR, 0.28; P = .001) and improved outcome in patients proceeding to allogeneic hematopoietic cell transplantation. 5-(N,N-hexamethylene)amiloride 76-79 P53 Homo sapiens 54-58 34785441-7 2022 Toxicity study using overexpression of dominant-negative mutant p53 in MCF-7 cells (which have wild type functional p53) showed that anticancer potential of compound 4h is positively correlated with p53 expression. 4h 166-168 P53 Homo sapiens 64-67 34728570-6 2022 Enzalutamide induced the expression of DNMT3A and DNMT3B in prostate cancer cells with a potential role of p53 and pRB in this process. enzalutamide 0-12 P53 Homo sapiens 107-110 34661718-0 2022 Hydroxyurea-loaded Fe3O4/SiO2/chitosan-g-mPEG2000 nanoparticles; pH-dependent drug release and evaluation of cell cycle arrest and altering p53 and lincRNA-p21 genes expression.

Puromycin 117-126 P53 Homo sapiens 72-75 31022952-4 2019 Puromycin exerted cytotoxic and anti-proliferative effects in p53 wild-type HCT116 more than in p53 null H1299 cells. Puromycin 0-9 P53 Homo sapiens 62-65 31022952-8 2019 Also, puromycin enhanced the antitumor effect with reactivating p53 and inducing tumor apoptosis (RITA) or doxorubicin in HCT116 cells. Puromycin 6-15 P53 Homo sapiens 64-67 31022952-9 2019 These findings suggest that puromycin induces p53-dependent apoptosis via upregulation of RPL5 or RPL11 for binding with MDM2, and so can be used more effectively in p53 wild-type cancers by combination with RITA or doxorubicin. Puromycin 28-37 P53 Homo sapiens 46-49 31022952-9 2019 These findings suggest that puromycin induces p53-dependent apoptosis via upregulation of RPL5 or RPL11 for binding with MDM2, and so can be used more effectively in p53 wild-type cancers by combination with RITA or doxorubicin. Puromycin 28-37 P53 Homo sapiens 166-169 31097990-3 2019 Library screening in assays that measure readthrough at a PTC in the TP53 gene in human HDQ-P1 cells identified six novel 2-aminothiazole-4-carboxamide derivatives that potentiate the PTC readthrough (PTCR) efficiency of G418 when used in combination. 2-aminothiazole-4-carboxamide 122-151 P53 Homo sapiens 69-73 30939155-5 2019 Our data showed that the statins-fluvastatin and lovastatin-induced p21 expression as general histone deacetylase inhibitors in a p53-independent manner, which is mediated through various pathways, such as apoptosis, autophagy, cell cycle progression, and DNA damage, to be involved in the function of p21 in HeLa cells.

Quercetin 26-35 P53 Homo sapiens 127-130 30664221-9 2019 However, quercetin did not alter the expression of the HPV E6 protein in cervical cancer cells; therefore, the increase in p53 occurred in an E6 expression-independent manner. Quercetin 9-18 P53 Homo sapiens 123-126 30664221-11 2019 These data suggest that quercetin increases the nuclear localization of p53 by interrupting E6/E6AP complex formation in cervical cancer cells.

Prostaglandins E 151-154 P53 Homo sapiens 22-25 31495738-6 2019 These observations are the first demonstration of the involvement of p53 in the control of healthy human ovarian cell functions, namely, in the downregulation of proliferation, in the upregulation of apoptosis, and in the alteration of PGF and PGE release, but not of P4, IGF-I, or OT. Prostaglandins E 244-247 P53 Homo sapiens 69-72 30947605-6 2019 Quercetin did not have any influence on the number of granulosa cells containing caspase 3, but at the concentration 10 mumol L-1 it inhibited p53 occurrence.

Niclosamide 0-11 P53 Homo sapiens 61-64 30258081-5 2018 Metabolome profiling reveals that niclosamide induces mitochondrial uncoupling, which renders mutant p53 cells susceptible to mitochondrial-dependent apoptosis through preferential accumulation of arachidonic acid (AA), and represents a first-in-class inhibitor of p53 mutant tumors.

Bortezomib 32-35 P53 Homo sapiens 88-91 27822577-7 2016 Live/dead staining assay for treated H1299 cells exhibited wider distribution, and higher dead staining was prominent in the HMSNs-PEI-BTZ-p53 group when compared to that of the HMSNs-BTZ group with equivalent BTZ concentration, which was consistent with accumulated p53 expression. Bortezomib 135-138 P53 Homo sapiens 139-142 27822577-7 2016 Live/dead staining assay for treated H1299 cells exhibited wider distribution, and higher dead staining was prominent in the HMSNs-PEI-BTZ-p53 group when compared to that of the HMSNs-BTZ group with equivalent BTZ concentration, which was consistent with accumulated p53 expression.

Melphalan 128-137 P53 Homo sapiens 75-78 28231749-8 2017 Moreover, MDM2 and p-MDM2 proteins were decreased, while p53 and p-p53 proteins were increased, both in a dose-dependent manner, after A549 treatment with total flavonoids and total tannins. Flavonoids 161-171 P53 Homo sapiens 67-70 28231749-10 2017 Our results indicated that total flavonoids and total tannins from SCR exerted a remarkable effect in reducing A549 growth through their action on mitochondrial pathway and disruption of MDM2-p53 balance.

Azacitidine 19-22 P53 Homo sapiens 52-55 27029827-7 2017 More efficient binding of the transcription factor p53 to pax5 promoter region is likely because SAHA increased accessibility of the chromatin conformation and Aza-demethylated DNA was more permissive, allowing transcription factors to bind.

Dichloroacetic Acid 100-103 P53 Homo sapiens 225-228 25544776-3 2015 DCA exhibited comparable cytotoxicity in p53wild-type and p53mutated B-CLL patient cell cultures, as well as in p53mutated B leukemic cell lines (MAVER, MEC-1, MEC-2). Dichloroacetic Acid 0-3 P53 Homo sapiens 41-44 24568186-11 2014 When MCF-7 cells were treated with the Fe(2+)-specific chelator phenanthroline, 15d-PGJ2-induced p53 expression was attenuated. ammonium ferrous sulfate 39-45 P53 Homo sapiens 97-100 31747859-2 2020 Our previous study showed that CDK4/Cyclin D1 phosphorylates p53-RS at the cancer-derived Ser249 and promotes its interaction with c-Myc in the nucleus, consequently enhancing c-Myc-dependent ribosomal biogenesis and HCC cell proliferation. seryl-seryl-seryl-arginine 90-93 P53 Homo sapiens 61-64 24308434-3 2014 Sensitivity of HMCLs to both drugs was correlated to p53: the BDM and melphalan median LD50 values of TP53(wild-type) HMCLs were more than two-fold lower than those of TP53(abnormal) HMCLs (p < 0.001), and p53 silencing in TP53(wt) NCI-H929 cells inhibited BDM- and melphalan-induced cell death.

Dichloroacetic Acid 0-3 P53 Homo sapiens 58-61 25544776-8 2015 Taken together, our results emphasize that DCA is a small molecule that merits further evaluation as a therapeutic agent also for p53mutated leukemic cells, by acting through the induction of a p53-independent pathway. Dichloroacetic Acid 43-46 P53 Homo sapiens 130-133 25544776-8 2015 Taken together, our results emphasize that DCA is a small molecule that merits further evaluation as a therapeutic agent also for p53mutated leukemic cells, by acting through the induction of a p53-independent pathway. Dichloroacetic Acid 43-46 P53 Homo sapiens 194-197 24308434-3 2014 Sensitivity of HMCLs to both drugs was correlated to p53: the BDM and melphalan median LD50 values of TP53(wild-type) HMCLs were more than two-fold lower than those of TP53(abnormal) HMCLs (p < 0.001), and p53 silencing in TP53(wt) NCI-H929 cells inhibited BDM- and melphalan-induced cell death. Melphalan 70-79 P53 Homo sapiens 102-106 32907379-6 2020 ADAR1 and cyclin D1 protein levels were dramatically decreased, while p53 and p21 levels were increased after 8-Cl-Ado exposure. 8-chloroadenosine 110-118 P53 Homo sapiens 70-73 25118938-5 2014 Inhibition of p53 activity with pifithrin-alpha or inhibition of PI3K with LY294002 suppressed CdCl2-induced cellular damage and elevation of Notch1-NICD. pifithrin 32-41 P53 Homo sapiens 14-17 25658320-7 2015 To a different extent, either the antioxidant N-acetyl-cysteine or the p53 inhibitor, Pifithrin-alpha, recover cell viability and decrease ROS formation. pifithrin 86-101 P53 Homo sapiens 71-74 32907379-9 2020 Together, 8-Cl-Ado inhibits the cell proliferation, induces G1 phase arrest and apoptosis at least by targeting ADAR1/p53/p21 signaling pathway. 8-chloroadenosine 10-18 P53 Homo sapiens 118-121 25658463-5 2015 We therefore sought to determine whether inhibiting WIP1 with a selective antagonist, GSK2830371, can attenuate neuroblastoma cell growth through reactivation of p53 mediated tumor suppression. GSK2830371 86-96 P53 Homo sapiens 162-165 32749126-6 2020 The effect of EGb761 on the p53 signaling pathway was further confirmed by adding pifithrin (PFT)-alpha, an inhibitor of p53. pifithrin 82-91 P53 Homo sapiens 28-31 25658463-6 2015 Neuroblastoma cell lines with wild-type TP53 alleles were highly sensitive to GSK2830371 treatment, while cell lines with mutant TP53 were resistant to GSK2830371. GSK2830371 78-88 P53 Homo sapiens 40-44 25658463-9 2015 Treatment of wild-type TP53 neuroblastoma cell lines with both GSK2830371 and either doxorubicin or carboplatin resulted in enhanced cell death, mediated through caspase 3/7 induction, as compared to either agent alone. GSK2830371 63-73 P53 Homo sapiens 23-27 25474301-6 2015 In addition, some small molecule drugs, such as rapamycin and its derivatives, rottlerin, PP242 and AZD8055 (targeting PI3K/AKT/mTORC1), spautin-1, and tamoxifen, as well as oridonin and metformin (targeting p53), can modulate autophagic pathways in different types of cancer.

Arsenic Trioxide 0-16 P53 Homo sapiens 72-75 25116336-4 2014 Previously, we found that arsenic trioxide (ATO), a drug for acute promyelocytic leukemia, degrades mutant p53 protein through a proteasome pathway. Arsenic Trioxide 26-42 P53 Homo sapiens 107-110 25116336-4 2014 Previously, we found that arsenic trioxide (ATO), a drug for acute promyelocytic leukemia, degrades mutant p53 protein through a proteasome pathway. Arsenic Trioxide 44-47 P53 Homo sapiens 107-110 25116336-8 2014 We also found that knockdown of Pirh2 inhibits, whereas ectopic expression of Pirh2 enhances, ATO-induced degradation of mutant p53 protein. Arsenic Trioxide 94-97 P53 Homo sapiens 128-131 25116336-10 2014 Interestingly, we found that ATO cooperates with HSP90 or HDAC inhibitor to promote mutant p53 degradation and growth suppression in tumor cells. Arsenic Trioxide 29-32 P53 Homo sapiens 91-94 25116336-11 2014 Together, these data suggest that ATO promotes mutant p53 degradation in part via induction of the Pirh2-dependent proteasome pathway. Arsenic Trioxide 34-37 P53 Homo sapiens 54-57 24374014-5 2015 p53 regulates many different aspects of metabolism, including glycolysis, mitochondrial oxidative phosphorylation, pentose phosphate pathway, fatty acid synthesis and oxidation, to maintain the homeostasis of cellular metabolism, which contributes to the role of p53 in tumor suppression. Pentosephosphates 115-132 P53 Homo sapiens 0-3 32749126-6 2020 The effect of EGb761 on the p53 signaling pathway was further confirmed by adding pifithrin (PFT)-alpha, an inhibitor of p53. pifithrin 82-91 P53 Homo sapiens 121-124 24374014-5 2015 p53 regulates many different aspects of metabolism, including glycolysis, mitochondrial oxidative phosphorylation, pentose phosphate pathway, fatty acid synthesis and oxidation, to maintain the homeostasis of cellular metabolism, which contributes to the role of p53 in tumor suppression.

Bleomycin 22-31 P53 Homo sapiens 58-61 25623255-13 2015 CONCLUSIONS: Our findings support our hypothesis that BM-derived PGE(2), through activation of cAMP-PKA signalling in BCP-ALL blasts, can inhibit the tumour suppressive activity of wild type p53, thereby promoting leukaemogenesis and protecting against therapy-induced leukaemic cell death.

Dichloroacetic Acid 110-113 P53 Homo sapiens 39-42 25019218-6 2014 As to its cytotoxic mechanism, we found that sulforaphane creates an oxidative cellular environment that induces DNA damage and Bax and p53 gene activation, which in turn helps trigger apoptosis. sulforaphane 45-57 P53 Homo sapiens 136-139 31905798-4 2019 Briefly, ent-kaur-15-en-17-al-18-oic acid protected cells from oxidative apoptosis associated with p53 and NF-kappaB pathways. ent-kaur-15-en-17-al-18-oic acid 9-41 P53 Homo sapiens 99-102 24836762-0 2014 Prognostic value of TP53 gene mutations in myelodysplastic syndromes and acute myeloid leukemia treated with azacitidine. Azacitidine 109-120 P53 Homo sapiens 20-24 24836762-2 2014 However, the impact of TP53 mutations in MDS treated with azacitidine (AZA) remains unclear. Azacitidine 58-69 P53 Homo sapiens 23-27 25896587-6 2015 When inhibiting the miR-34a, the sensitivity of the cells to quercetin decreased and the expression of the SIRT1 was up-regulated, but the acetylation of p53 and the expression of some genes related to p53 down-regulated. Quercetin 61-70 P53 Homo sapiens 202-205 25896587-7 2015 CONCLUSION: miR-34a plays an important role in the anti-tumor effects of querctin in HCC, miR-34a may be a tiemolecule between the p53 and SIRT1 and is composed of a p53/miR-34a/SIRT1 signal feedback loop, which could enhance apoptosis signal and significantly promote cell apoptosis. querctin 73-81 P53 Homo sapiens 131-134 25896587-7 2015 CONCLUSION: miR-34a plays an important role in the anti-tumor effects of querctin in HCC, miR-34a may be a tiemolecule between the p53 and SIRT1 and is composed of a p53/miR-34a/SIRT1 signal feedback loop, which could enhance apoptosis signal and significantly promote cell apoptosis. querctin 73-81 P53 Homo sapiens 166-169 25641429-5 2015 Furthermore, the enhancement of p53-dependent apoptosis by flavokawain B could be rescued by pifithrin-alpha, a pharmacological inhibitor of p53 transcriptional activity. pifithrin 93-108 P53 Homo sapiens 32-35 25641429-5 2015 Furthermore, the enhancement of p53-dependent apoptosis by flavokawain B could be rescued by pifithrin-alpha, a pharmacological inhibitor of p53 transcriptional activity. pifithrin 93-108 P53 Homo sapiens 141-144 25474278-9 2014 The post-progression survival (PPS) of p53-positive patients undergoing 2nd and/or 3rd line chemotherapy with irinotecan and/or cetuximab was significantly longer compared to p53-negative patients. pps 31-34 P53 Homo sapiens 39-42 24836762-3 2014 We analyzed TP53 mutations in 62 patients with high risk MDS or AML treated with AZA. Azacitidine 81-84 P53 Homo sapiens 12-16 24836762-9 2014 Thus, TP53 mutations strongly correlated with poorer survival in higher risk MDS and AML treated with AZA.

Sorafenib 0-9 P53 Homo sapiens 140-143 22006587-8 2013 The sorafenib and nutlin-3 co-treatment lead to enhanced levels of p53, p-p53, and increase in the levels of p53 pro-apoptotic effector PUMA, Bax, and decrease in the anti-apoptotic Bcl-2 levels. Sorafenib 4-13 P53 Homo sapiens 67-70 22006587-8 2013 The sorafenib and nutlin-3 co-treatment lead to enhanced levels of p53, p-p53, and increase in the levels of p53 pro-apoptotic effector PUMA, Bax, and decrease in the anti-apoptotic Bcl-2 levels. Sorafenib 4-13 P53 Homo sapiens 74-77 22006587-8 2013 The sorafenib and nutlin-3 co-treatment lead to enhanced levels of p53, p-p53, and increase in the levels of p53 pro-apoptotic effector PUMA, Bax, and decrease in the anti-apoptotic Bcl-2 levels. Sorafenib 4-13 P53 Homo sapiens 74-77 23153533-2 2012 We found that the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1), commonly upregulated in human cancers due to loss of TP53, contributes to biosynthesis regulation in part by controlling intracellular levels of its substrate, 3-phosphoglycerate (3-PG), and product, 2-phosphoglycerate (2-PG). 2-phosphoglycerate 271-289 P53 Homo sapiens 124-128 22006587-9 2013 Importantly, our studies revealed that sorafenib alone can activate p53 in a concentration dependent manner. Sorafenib 39-48 P53 Homo sapiens 68-71 28849235-1 2017 Cellular tumor antigen p53 (p53) functions to maintain genomic stability and regulate cell apoptosis, while G protein-coupled receptor class C group 5 member A (GPCR5A) is a lung cancer suppressor gene whose expression is induced by retinoids. Retinoids 233-242 P53 Homo sapiens 0-26 22006587-10 2013 Thus, co-treatment of nutlin-3 with sorafenib leads to increased half-life of p53, which in turn can be activated by sorafenib, to induce downstream pro-apoptotic and anti-proliferative effects. Sorafenib 36-45 P53 Homo sapiens 78-81 22006587-10 2013 Thus, co-treatment of nutlin-3 with sorafenib leads to increased half-life of p53, which in turn can be activated by sorafenib, to induce downstream pro-apoptotic and anti-proliferative effects.

Methyl Methanesulfonate 0-23 P53 Homo sapiens 95-98 23117069-1 2012 Methyl methanesulfonate (MMS) has been shown to induce apoptosis in various cell types through p53-dependent pathways. Methyl Methanesulfonate 25-28 P53 Homo sapiens 95-98 28901493-0 2017 High pemetrexed sensitivity of docetaxel-resistant A549 cells is mediated by TP53 status and downregulated thymidylate synthase. Pemetrexed 5-15 P53 Homo sapiens 77-81 23117069-2 2012 Nevertheless, pharmacological and genetic blockade of p53 functions results in similar or delayed sensitivity to MMS treatment, suggesting the presence of p53-independent apoptotic mechanisms. Methyl Methanesulfonate 113-116 P53 Homo sapiens 54-57 23117069-3 2012 To understand the p53-independent mechanisms that are engaged during MMS-induced apoptosis, we established MMS-induced apoptotic cell models using p53-deficient H1299 and Hep3B cells. Methyl Methanesulfonate 107-110 P53 Homo sapiens 147-150 23117069-7 2012 These results demonstrated a p53- and p73-independent mechanism for MMS-induced apoptosis that involves the nuclear-cytosolic translocation of active caspase 2 as well as the mitochondria-mediated pathway. Methyl Methanesulfonate 68-71 P53 Homo sapiens 29-32 23368925-11 2013 Our novel findings demonstrate that OL limits the growth and induces apoptosis in HT-29 cells via p53 pathway activation adapting the HIF-1alpha response to hypoxia. oleuropein 36-38 P53 Homo sapiens 98-101 23859040-5 2013 The presence of pifithrin, an inhibitor of p53 function, blocked ECG-induced apoptosis as was manifested by restored cell viability and caspase-3 activity to control values and reestablished the balance among Bcl-2 anti- and proapoptotic protein levels. pifithrin 16-25 P53 Homo sapiens 43-46 22689683-10 2012 CONCLUSIONS: Our data demonstrate that acute myeloid leukemia cells show a variable but overall good susceptibility to the innovative therapeutic combination of sorafenib+nutlin-3, which differentially involves the pro-apoptotic Bcl-2 family members Bax and Bak in p53(wild-type) and p53(deleted) cells. Sorafenib 161-170 P53 Homo sapiens 265-268 28901493-0 2017 High pemetrexed sensitivity of docetaxel-resistant A549 cells is mediated by TP53 status and downregulated thymidylate synthase. Docetaxel 31-40 P53 Homo sapiens 77-81 22689683-10 2012 CONCLUSIONS: Our data demonstrate that acute myeloid leukemia cells show a variable but overall good susceptibility to the innovative therapeutic combination of sorafenib+nutlin-3, which differentially involves the pro-apoptotic Bcl-2 family members Bax and Bak in p53(wild-type) and p53(deleted) cells. Sorafenib 161-170 P53 Homo sapiens 284-287 24379902-2 2013 However, U373MG malignant glioma cells expressing mutant p53 are resistant to a 24 h quercetin treatment. Quercetin 85-94 P53 Homo sapiens 57-60 24379902-5 2013 Furthermore, quercetin activated JNK and increased the expression of p53, which translocated to the mitochondria and simultaneously led to the release of cytochrome c from mitochondria to the cytosol. Quercetin 13-22 P53 Homo sapiens 69-72 28901493-9 2017 The level of TS protein was significantly decreased in wild-type TP53-containing cells with DOC treatment; TS expression levels were not affected in mutant-TP53 and TP53-null cells under the same conditions. Docetaxel 92-95 P53 Homo sapiens 65-69 29110583-10 2017 Meanwhile, at the protein level, beta-mangostin activated the formation of cleaved caspase-3 and caspase-9 and also upregulated the p53. beta-Mangostin 33-47 P53 Homo sapiens 132-135 22893484-7 2012 5-AZA down-regulated MCL-1, known to mediate resistance to ABT-737, in a p53-independent manner. Azacitidine 0-5 P53 Homo sapiens 73-76 23285810-2 2012 For the first time, our study indicated that neohesperidin also induces cell apoptosis in human breast adenocarcinoma MDA-MB-231 cells, which was possibly mediated by regulating the P53/Bcl-2/Bax pathway. neohesperidin 45-58 P53 Homo sapiens 182-185 23091481-0 2012 Induction of p53-inducible microRNA miR-34 by gamma radiation and bleomycin are different. Bleomycin 66-75 P53 Homo sapiens 13-16 29212215-5 2017 We examined the molecular mechanism of this cell death pathway, and found that B2 protein induces the P53/Bax-mediated apoptotic pathway in A549 cells, and that a P53 specific inhibitor (pifithrin-alpha) switches this response to RIP3-mediated necroptosis. pifithrin 187-196 P53 Homo sapiens 102-105 29623239-5 2012 Forskolin treatment for up to 72 h resulted in 80% syncytialization, increased expression of Bcl-2 protein (P < 0.01) and mRNA (P < 0.05), and significantly decreased expression of protein and mRNA for Bax, p53, and caspases 3 and 8. Colforsin 0-9 P53 Homo sapiens 213-216 23068099-6 2012 Although CAF-specific ER-activating abilities varied among individual cases, all CAFs maintained wild-type alleles for TP53 and PTEN. cafs 81-85 P53 Homo sapiens 119-123 29212215-5 2017 We examined the molecular mechanism of this cell death pathway, and found that B2 protein induces the P53/Bax-mediated apoptotic pathway in A549 cells, and that a P53 specific inhibitor (pifithrin-alpha) switches this response to RIP3-mediated necroptosis. pifithrin 187-196 P53 Homo sapiens 163-166 28573904-0 2017 Dichloroacetonitrile induces cytotoxicity through oxidative stress-mediated and p53-dependent apoptosis pathway in LO2 cells. dichloroacetonitrile 0-20 P53 Homo sapiens 80-83 22922338-10 2012 Finally, capsazepine downregulated the expression of various antiapoptotic proteins (e.g., cFLIP and survivin) and increased the expression of proapoptotic proteins (e.g., Bax and p53). capsazepine 9-20 P53 Homo sapiens 180-183 22948151-6 2012 Induction of p53 can be achieved by several means, such as UV radiation and treatment with anti-cancer agents (including doxorubicin, etoposide, roscovitine, flavopiridol, and nutlin-3). Roscovitine 145-156 P53 Homo sapiens 13-16 22765290-3 2012 In this review, we focus on highlighting several representative plant natural compounds such as curcumin, resveratrol, paclitaxel, oridonin, quercetin and plant lectin - that may lead to cancer cell death - for regulation of some core autophagic pathways, involved in Ras-Raf signalling, Beclin-1 interactome, BCR-ABL, PI3KCI/Akt/mTOR, FOXO1 signalling and p53. Quercetin 141-150 P53 Homo sapiens 357-360 22791815-0 2012 Chromium (VI) induces both bulky DNA adducts and oxidative DNA damage at adenines and guanines in the p53 gene of human lung cells.

Guanine 86-94 P53 Homo sapiens 102-105 22213398-8 2012 Finally, we isolated ursolic and oleanolic acids as the bioactive compounds able to upregulate p53 expression and inhibit breast cancer cell growth. Oleanolic Acid 33-48 P53 Homo sapiens 95-98 22593008-3 2012 For this purpose, a amonafide analogue, 7-d (2-(3-(2-(Dimethylamino)ethylamino)propyl)-6-(dodecylamino)-1H-benzo[de]isoquinoline-1,3(2H)-dione) was screened, which exhibited high antitumor activity against p53-deficient human Chronic Myelogenous Leukemia (CML) K562 cells. 2-(3-(2-(dimethylamino)ethylamino)propyl)-6-(dodecylamino)-1H-benzo(de)isoquinoline-1,3(2H)-dione 45-142 P53 Homo sapiens 206-209 22791815-2 2012 However, both adenine (A) and guanine (G) mutations are found in the p53 gene in Cr exposure-related lung cancer. Adenine 14-21 P53 Homo sapiens 69-72 28573904-7 2017 Therefore, we conclude that DCAN may activate apoptotic signals via p53 up-regulation and oxidative stress-mediated apoptosis in LO2 cells. dichloroacetonitrile 28-32 P53 Homo sapiens 68-71 22791815-2 2012 However, both adenine (A) and guanine (G) mutations are found in the p53 gene in Cr exposure-related lung cancer. Guanine 30-37 P53 Homo sapiens 69-72 22791815-5 2012 To understand the causes for these Cr-induced DNA damages, we mapped the distribution of BDA adducts and ODD in the p53 gene DNA fragments induced by Cr(III), Cr(VI) and Cr(V), the three major cellular Cr forms. bda 89-92 P53 Homo sapiens 116-119 23017148-1 2012 BACKGROUND: Nucleoside analogs used in the chemotherapy of solid tumors, such as the capecitabine catabolite 5"-deoxy-5-fluorouridine (5"-DFUR) trigger a transcriptomic response that involves the aquaglyceroporin aquaporin 3 along with other p53-dependent genes. Nucleosides 12-22 P53 Homo sapiens 242-245 22791815-9 2012 We propose that these Cr(VI)-induced BDA and ODD contribute to mutagenesis of the p53 gene that leads to lung carcinogenesis. bda 37-40 P53 Homo sapiens 82-85 22993307-4 2012 Activation of p53 accounted for, at least in part, the growth inhibition by CHO27 in vitro. cho27 76-81 P53 Homo sapiens 14-17 28927457-2 2017 All-trans retinoic acid (ATRA) and isotretinoin (13-cis retinoic acid) enhance p53 expression.

Pentosephosphates 82-99 P53 Homo sapiens 22-25 21336310-4 2011 Here we show that the tumour suppressor p53, the most frequently mutated gene in human tumours, inhibits the pentose phosphate pathway (PPP). Pentosephosphates 109-126 P53 Homo sapiens 40-43 27352049-9 2016 Increased expression of a p53 dimer in 3D-cultured LNCaP cells was correlated with increased resistance to Docetaxel.

Ribavirin 13-22 P53 Homo sapiens 54-57 19619545-5 2009 Furthermore, ribavirin-induced activation of mTOR and p53 enhances IFN-dependent signaling for the IFN-alpha/ribavirin combined treatment. Ribavirin 109-118 P53 Homo sapiens 54-57 19619545-6 2009 We conclude that ribavirin enhances activities of mTOR and p53, which may account for its antiviral and antitumor effects. Ribavirin 17-26 P53 Homo sapiens 59-62 20064791-0 2010 Associations between polycyclic aromatic hydrocarbon-related exposures and p53 mutations in breast tumors. Polycyclic Aromatic Hydrocarbons 21-52 P53 Homo sapiens 75-78 19816711-6 2010 Western blotting also showed that cucurbitacin E treatment can inhibit STAT3 phosphorylation while upregulate p53 expression. cucurbitacin E 34-48 P53 Homo sapiens 110-113 26892186-8 2016 VOA-induced autophagy was mediated through a p53/AMPK/mTOR signaling pathway in A172 cells, while an mTOR-independent signaling pathway in U251 cells. voa 0-3 P53 Homo sapiens 45-48 19646415-4 2009 Inhibition of NF-kappaB or p53 activation by its specific inhibitor PDTC or pifithrin-alpha respectively, significantly reduced both oridonin-induced apoptosis and autophagy accompanied by the decrease in Beclin 1 and LC3 levels. pifithrin 76-91 P53 Homo sapiens 27-30 26865041-5 2016 Furthermore, the perichondral spindle cells and marrow osteoblasts/fibroblasts of BPOP showed stronger immunoreaction of PCNA, p53, beta-catenin, BCL2, pAKT, survivin, 14-3-3, CEA, EMA, pan-K, and S-100 than the tumor cells of osteochondroma. bpop 82-86 P53 Homo sapiens 127-130 19184017-7 2009 Importantly, pifithrin-alpha, a p53 inhibitor, protected against DOX-induced mitochondrial depolarization, caspase activation and cell death. pifithrin 13-22 P53 Homo sapiens 32-35 19524575-2 2009 HCCs from AFB(1)-exposed individuals frequently have distinct TP53 mutations, such as G to T transversions in the second guanine of codon 249 (AGG to AGT), and a characteristic mutational spectrum predominated by G:C to T:A mutations. Guanine 121-128 P53 Homo sapiens 62-66 19465072-4 2009 Effectiveness of the Pas segment in the intracellular delivery of bioactive peptides using arginine-rich CPPs was exemplified through the enhanced growth inhibition activity of the malignant glioma cells by a retro-inverso peptide derived from the p53 C-terminal 22-amino-acid segment (positions 361-382). Aminosalicylic Acid 21-24 P53 Homo sapiens 248-251 20096120-9 2010 CONCLUSIONS: Our findings, for the first time, unify the current inconsistent findings for bortezomib treatment and survivin expression, and linked the effect of bortezomib on survivin expression, apoptosis induction and bortezomib resistance in the relationship with p53 status, which is independent of cancer cell types. Bortezomib 162-172 P53 Homo sapiens 268-271 20096120-9 2010 CONCLUSIONS: Our findings, for the first time, unify the current inconsistent findings for bortezomib treatment and survivin expression, and linked the effect of bortezomib on survivin expression, apoptosis induction and bortezomib resistance in the relationship with p53 status, which is independent of cancer cell types. Bortezomib 162-172 P53 Homo sapiens 268-271 19608275-7 2010 The enhanced cytotoxicity of ATO+bortezomib was associated with augmented STAT3 inhibition and JNK activation, up-regulation of Bim, p21, p27, p53 as well as down-regulation of Bcl-2. Bortezomib 33-43 P53 Homo sapiens 143-146 26865836-11 2015 ICC analysis for bcl2 and p53 also confirmed our results; in treated samples for the dose of LD50 in 24 and 48 h of cisplatin and hypercin, more cells expressed p53 (guardian of cells in front of tumor formation/progression) and less expressed bcl2 (which has anti apoptotic activity) compared to untreated samples. hypercin 130-138 P53 Homo sapiens 26-29 21499441-9 2010 Together this data indicate that the lack of PP1 activation in AT cells result in increased NPM and NCL protein levels which prevents p53 phosphorylation in response to bleomycin and contributes to a defective G2/M checkpoint. Bleomycin 169-178 P53 Homo sapiens 134-137 19625696-5 2009 BCL2-related protein A1, hedgehog interacting protein, and p53 target zinc finger protein genes were downregulated to 26-52% of the control, because of methylselenol exposure. methaneselenol 152-165 P53 Homo sapiens 59-62 19661301-7 2009 Stable down-regulation of p53 expression by siRNA led to attenuation of bortezomib effects, survivin down-regulation and p21 induction, suggesting that cellular effects are p53-dependent. Bortezomib 72-82 P53 Homo sapiens 26-29 19661301-7 2009 Stable down-regulation of p53 expression by siRNA led to attenuation of bortezomib effects, survivin down-regulation and p21 induction, suggesting that cellular effects are p53-dependent.

Bortezomib 76-86 P53 Homo sapiens 161-164 26865836-11 2015 ICC analysis for bcl2 and p53 also confirmed our results; in treated samples for the dose of LD50 in 24 and 48 h of cisplatin and hypercin, more cells expressed p53 (guardian of cells in front of tumor formation/progression) and less expressed bcl2 (which has anti apoptotic activity) compared to untreated samples. hypercin 130-138 P53 Homo sapiens 161-164 19723057-4 2009 In the present study, we examined the effects of 15d-PGJ(2) on activation of p53 tumor suppressor in human breast cancer (MCF-7) cells. 15d-pgj 49-56 P53 Homo sapiens 77-80 19723057-5 2009 MCF-7 cells treated with 15d-PGJ(2) exhibited elevated p53 protein expression in time- and concentration-related manners, whereas prostaglandin A(2) (PGA(2)) and the nonprostaglandin derivative 2-cyclopenten-1-one exerted an effect to a lesser extent than did 15d-PGJ(2). 15d-pgj 25-32 P53 Homo sapiens 55-58 19956882-0 2010 p53 independent radio-sensitization of human lymphoblastoid cell lines by Hsp90 inhibitor 17-allylamino-17-demethoxygeldanamycin. tanespimycin 90-128 P53 Homo sapiens 0-3 26523671-4 2016 We found that the expression level of miR-34a induced by the DNA damage agent adrmycin (ADR) was both p53- and time-dependent. adrmycin 78-86 P53 Homo sapiens 102-105 21071999-0 2010 Pifithrin-alpha, an inhibitor of p53 transactivation, up-regulates COX-2 expression through an MAPK-dependent pathway. pifithrin 0-15 P53 Homo sapiens 33-36 21071999-2 2010 In this study, we investigated the effect of pifithrin (PFT)-alpha, an inhibitor of p53 transactivation, on COX-2 expression in breast and fibrosarcoma cells. pifithrin 45-54 P53 Homo sapiens 84-87 19497413-8 2009 Although both compounds are weakly but equally effective inhibitors of iNOS protein expression and activity, only Se-PBIT significantly enhanced the levels of p53, p38, p27 and p21 protein expression, reduced levels of phospholipase A2 (PLA2) but had no effect on cyclooxygenase-2 (COX-2) protein levels; such molecular targets are involved in cell growth inhibition, induction of apoptosis and cell cycle regulation. se-pbit 114-121 P53 Homo sapiens 159-162 26694952-0 2016 ARTIK-52 induces replication-dependent DNA damage and p53 activation exclusively in cells of prostate and breast cancer origin.

SMIFH2 compound 86-92 P53 Homo sapiens 152-155 17849424-8 2008 The highly significant association between NTS, reflecting chronic NO-induced cellular protein damage, and endogenous p53 mutations at CpG dinucleotides, provides further evidence for a molecular link between chronic inflammation and esophageal malignancy. 3-nitrotyrosine 43-46 P53 Homo sapiens 118-121 18096571-9 2008 Taken together, these data suggest that (1) Mdm2 is a sensitive biomarker for certain types of genotoxicity, and (2) that polycyclic aromatic hydrocarbons-induced Mdm2 binding to chromatin reflects repairable damage, whereas chromatin binding of p53 Ser15 and gammaH2AX indicates more persistent DNA damage. Polycyclic Aromatic Hydrocarbons 122-154 P53 Homo sapiens 246-249 17938270-7 2007 Moreover, epothilone B and D increased the expressions of NF-kappaB-dependent apoptotic cell death regulatory genes, i.e., Bax, p53, and the active form of caspase-3, but reduced Bcl-2 expression, and these actions were partially reversed by salicylic acid. Deuterium 27-28 P53 Homo sapiens 128-131 17914225-4 2007 By computing the free energies of wild-type and mutant p53c binding to DNA and decomposing them into contributions from individual residues, the DNA-binding loss upon charge/noncharge -conserving mutation of Arg 273 was attributed not only to the loss of DNA phosphate contacts, but also to longer-range structural changes caused by the loss of the Asp 281 salt-bridge. Aspartic Acid 349-352 P53 Homo sapiens 55-58 17914225-5 2007 The results herein and in previous works suggest that Asp 281 plays a critical role in the sequence-specific DNA-binding function of p53c by (i)orienting Arg 273 and Arg 280 in an optimal position to interact with the phosphate and base groups of the consensus DNA, respectively, and (ii) helping to maintain the proper DNA-binding protein conformation.

Docetaxel 104-113 P53 Homo sapiens 258-261 17637740-2 2008 We found that the cytotoxic drugs methotrexate (MTX) and 5-fluorouracil (5-FU) were both able to sensitize resistant tumor cells for induction of apoptosis by p53-mediated upregulation of caspase-8. Methotrexate 34-46 P53 Homo sapiens 159-162 26131123-11 2015 CONCLUSIONS: These results confirmed that honokiol could induce apoptosis and cell cycle arrest, the underlying molecular mechanisms, at least partially, through activation p53 signaling and downregulation CDC2/cdc25C expression. honokiol 42-50 P53 Homo sapiens 173-176 17637740-2 2008 We found that the cytotoxic drugs methotrexate (MTX) and 5-fluorouracil (5-FU) were both able to sensitize resistant tumor cells for induction of apoptosis by p53-mediated upregulation of caspase-8. Methotrexate 48-51 P53 Homo sapiens 159-162 25575314-3 2015 While pifithrin-alpha, a specific p53 inhibitor, induced cell cycle arrest in G1 phase. pifithrin 6-21 P53 Homo sapiens 34-37 18160328-0 2008 Clioquinol inhibits peroxide-mediated toxicity through up-regulation of phosphoinositol-3-kinase and inhibition of p53 activity. Clioquinol 0-10 P53 Homo sapiens 115-118 17340621-11 2007 In addition, inhibition of CD95/Fas receptor on the cell surface of MCF-EGFP cells by treatment with Pifithrin-alpha, a p53 specific transactivation inhibitor, partially abrogated the sensitivity of bystander MCF-EGFP cells. pifithrin 101-116 P53 Homo sapiens 120-123 17406354-3 2007 Here, we show that the transient transfection of the proline allele in p53 null cancer cells exposed to low oxygen tension or to the hypoxia-mimetic drug Desferoxamine induces a higher amount of cell death than the arginine allele. desferoxamine 154-167 P53 Homo sapiens 71-74 17276690-8 2007 Thus, our novel naphthoindole based derivative of tryptamine gained new activities important for anticancer therapy, namely, suppression of topoisomerase I and the ability to overcome resistance mediated by P-glycoprotein expression and p53 dysfunction. naphthoindole 16-29 P53 Homo sapiens 237-240 25575314-4 2015 Although 1, 2 and pifithrin-alpha caused serious inhibition on p53, 1 and 2 significantly cause the loss of mitochondrial membrane potential and increase of the reactive oxygen species level, cytochrome c, apaf-1 and caspase-3/9 ratio in BEL-7404 cells. pifithrin 18-27 P53 Homo sapiens 63-75 25767399-2 2015 METHODS: The expression level of p53 protein was detected by immunohistochemistry in primary early-stage ER-positive breast tumor specimens from 293 postmenopausal breast cancer patients who received first-line AI treatment (letrozole, anastrozole, or exemestane) until relapse, and analysis was performed to determine whether expression of p53 protein affected the response to endocrine therapy. exemestane 252-262 P53 Homo sapiens 33-36 17235352-1 2007 In this report, the effects of a combined treatment with the proteasome inhibitor bortezomib and either a recombinant adeno-associated virus type 2 (rAAV-2)-mediated p53 gene transfer or chemotherapeutic agents, docetaxel and pemetrexed, were tested on p53 positive and p53negative non-small cell lung cancer (NSCLC) cell lines.

Vinblastine 26-37 P53 Homo sapiens 70-73 18094076-8 2008 In KB-3 cells, which have compromised p53 function, and in p53-null cells but not in p53 wild-type cells, vinblastine caused down-regulation of p21 expression concomitant with increased c-Jun expression, suggesting a role for c-Jun in negative regulation of the p21 promoter independent of p53. Vinblastine 106-117 P53 Homo sapiens 38-41 18094076-8 2008 In KB-3 cells, which have compromised p53 function, and in p53-null cells but not in p53 wild-type cells, vinblastine caused down-regulation of p21 expression concomitant with increased c-Jun expression, suggesting a role for c-Jun in negative regulation of the p21 promoter independent of p53. Vinblastine 106-117 P53 Homo sapiens 59-62 18094076-8 2008 In KB-3 cells, which have compromised p53 function, and in p53-null cells but not in p53 wild-type cells, vinblastine caused down-regulation of p21 expression concomitant with increased c-Jun expression, suggesting a role for c-Jun in negative regulation of the p21 promoter independent of p53. Vinblastine 106-117 P53 Homo sapiens 59-62 18094076-8 2008 In KB-3 cells, which have compromised p53 function, and in p53-null cells but not in p53 wild-type cells, vinblastine caused down-regulation of p21 expression concomitant with increased c-Jun expression, suggesting a role for c-Jun in negative regulation of the p21 promoter independent of p53. Vinblastine 106-117 P53 Homo sapiens 59-62 25557114-13 2015 CONCLUSION: Sorafenib inhibits HCC proliferation and invasion by inhibiting MMP-2 and Ki-67 expression due to up-regulation of P53 and suppressing FoxM1. Sorafenib 12-21 P53 Homo sapiens 127-130 17855337-6 2007 Furthermore, RNA interference-mediated lowering of the p53 protein in T1 cells or pifithrin-alpha-induced p53-specific inhibition activity significantly decreased CTL-induced target killing mediated by CTL or recombinant GrB. pifithrin 82-91 P53 Homo sapiens 106-109 17855337-9 2007 Treatment of T1 cells with pifithrin-alpha resulted in inhibition of p53 phosphorylation at these residues and in a significant decrease in GrB-induced apoptotic T1 cell death. pifithrin 27-36 P53 Homo sapiens 69-72 16821082-0 2007 Possible involvement of CCT5, RGS3, and YKT6 genes up-regulated in p53-mutated tumors in resistance to docetaxel in human breast cancers. Docetaxel 103-112 P53 Homo sapiens 67-70 16821082-1 2007 BACKGROUND: Present study was aimed to investigate the relationship of p53 mutation status with response to docetaxel in breast cancers. Docetaxel 108-117 P53 Homo sapiens 71-74 25444910-6 2015 By contrast, arsenic trioxide, which by inhibiting wild-type p53-induced phosphatase-1 that serves responses downstream of p53, and by depolymerizing tubulin, synergistically enhanced cisplatin cytotoxicity including loss of SP cells. Arsenic Trioxide 13-29 P53 Homo sapiens 61-64 16821082-2 2007 In addition, attempts were made to identify the genes differentially expressed between p53-wild and p53-mutated breast tumors and to study their relationship with response to docetaxel. Docetaxel 175-184 P53 Homo sapiens 100-103 16821082-3 2007 METHODS: Mutational analysis of p53 was done in 50 breast tumor samples obtained from primary breast cancer patients (n = 33) and locally recurrent breast cancer patients (n = 17) before docetaxel therapy. Docetaxel 187-196 P53 Homo sapiens 32-35 16821082-8 2007 Of these 13 genes, mRNA expression of CCT5, RGS3, and YKT6 was significantly up-regulated in p53-mutated tumors and associated with a low response rate to docetaxel. Docetaxel 155-164 P53 Homo sapiens 93-96 16821082-10 2007 CONCLUSIONS: CCT5, RGS3, and YKT6 mRNA expressions, which are up-regulated in p53-mutated breast tumors, might be implicated in resistance to docetaxel and clinically useful in identifying the subset of breast cancer patients who may or may not benefit from docetaxel treatment. Docetaxel 142-151 P53 Homo sapiens 78-81 17900801-5 2007 Combining the Chk1 inhibitor UCN-01 dramatically enhanced the response to AG490 in p53-mutated or deleted glioma cells. 7-hydroxystaurosporine 29-35 P53 Homo sapiens 83-86 25453767-7 2015 However, the most pronounced anti-epileptic effect was observed in rosuvastatin-treated animals, which was associated with improved blood-brain barrier (BBB) integrity, increased expression of endothelial nitric oxide synthase (eNOS) mRNA and decreased expressions of pro-apoptotic p53, Bax and caspase-3 mRNAs. Rosuvastatin Calcium 67-79 P53 Homo sapiens 282-285 17910628-6 2007 Bortezomib/PXD101 treatment markedly triggered reactive oxygen species (ROS) generation that was accompanied by p53, H2A.X and p38-mitogen-activated protein kinase phosphorylation. Bortezomib 0-10 P53 Homo sapiens 112-115 16821082-10 2007 CONCLUSIONS: CCT5, RGS3, and YKT6 mRNA expressions, which are up-regulated in p53-mutated breast tumors, might be implicated in resistance to docetaxel and clinically useful in identifying the subset of breast cancer patients who may or may not benefit from docetaxel treatment.

Plicamycin 0-3 P53 Homo sapiens 104-107 25453767-10 2015 Here, we provide evidence that among HMG-CoA reductase inhibitors, rosuvastatin was the most effective statin on the reduction of epileptiform activity, which was associated with improved BBB permeability, increased expression of eNOS and decreased expressions of pro-apoptotic p53, Bax and caspase-3. Rosuvastatin Calcium 67-79 P53 Homo sapiens 278-281 17557903-13 2007 As observed in humans, p53 plays a protective role in colitis-associated neoplasia in the DSS model. Dextran Sulfate 90-93 P53 Homo sapiens 23-26 26119958-7 2015 Using p53(-/-) and p53(+/+) HCT-116 cells, we confirmed that p53/p21 was the main pathway that contributed to the G2/M cell cycle arrest by 6-shogaol. shogaol 140-149 P53 Homo sapiens 6-9 17224176-7 2007 Moreover, we compared side-by-side the activity of four prominent human 3"-5" exonucleases (WRN, APE1, TREX1, and p53) on substrates containing 3" phosphates, phosphoglycolates, and tyrosyl residues. cyclo(tyrosyl-tyrosyl) 182-189 P53 Homo sapiens 114-117 26119958-7 2015 Using p53(-/-) and p53(+/+) HCT-116 cells, we confirmed that p53/p21 was the main pathway that contributed to the G2/M cell cycle arrest by 6-shogaol. shogaol 140-149 P53 Homo sapiens 19-22 18024399-2 2007 DESIGN AND METHODS: Melphalan-induced damage formation and repair of monoadducts and interstrand cross-links in the p53 gene were studied in peripheral blood mononuclear cells obtained from 32 patients prior to therapy.

Quercetin 48-57 P53 Homo sapiens 4-7 17487067-12 2007 HepG2 cells exposed to arsenic trioxide and PFT-alpha showed expression of only the P53 and PCNA genes. Arsenic Trioxide 23-39 P53 Homo sapiens 84-87 25896587-5 2015 RESULTS: miR-34a was up-regulated in HepG2 cells treated by quercetin exhibiting wild-type p53. Quercetin 60-69 P53 Homo sapiens 91-94 17938262-5 2007 Exposure of PC-3 and LNCaP cells to honokiol resulted in the induction of p21 (PC-3 and LNCaP) and p53 protein expression (LNCaP). honokiol 36-44 P53 Homo sapiens 99-102 28970873-5 2015 The transformation of the azidophenyl label to nitrophenyltriazole was used for electrochemical detection of DNA-protein interactions (p53 protein) since only those azidophenyl groups in the parts of the DNA not shielded by the bound p53 protein were transformed to nitrophenyltriazoles, whereas those covered by the protein were not. nitrophenyltriazoles 266-286 P53 Homo sapiens 135-138 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. beta-elemene 16-28 P53 Homo sapiens 94-97 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. beta-elemene 16-28 P53 Homo sapiens 119-122 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. beta-elemene 16-28 P53 Homo sapiens 119-122 18001220-7 2007 The increase in apoptosis following quercetin exposure was p53/Bax mediated and correlated with a decrease in GST-driven bioreduction capacity and an increase in ROS. Quercetin 36-45 P53 Homo sapiens 59-62 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. Docetaxel 34-43 P53 Homo sapiens 94-97 25737737-6 2015 Treatment of cells with pifithrin-alpha, a specific inhibitor of p53, suppressed shikonin-induced apoptosis and premature senescence, suggesting the role of p53 in mediating the actions of shikonin on regulation of lung cancer cell proliferation. pifithrin 24-39 P53 Homo sapiens 65-68 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. Docetaxel 34-43 P53 Homo sapiens 119-122 17611679-5 2007 Combinations of beta-elemene with docetaxel induced much stronger synergistic interactions in p53 mutant H23 cells and p53 null H358 cells than in p53 wild-type H460 and A549 cells. Docetaxel 34-43 P53 Homo sapiens 119-122 17611679-8 2007 In H460 and A549 cells, dose-dependent upregulation of p53 protein expression was observed in cultures treated with docetaxel alone and with docetaxel plus beta-elemene, whereas no significant change in p53 expression was observed in any of the treatment groups in H23 cells. Docetaxel 116-125 P53 Homo sapiens 55-58 17611679-8 2007 In H460 and A549 cells, dose-dependent upregulation of p53 protein expression was observed in cultures treated with docetaxel alone and with docetaxel plus beta-elemene, whereas no significant change in p53 expression was observed in any of the treatment groups in H23 cells. Docetaxel 141-150 P53 Homo sapiens 55-58 17611679-8 2007 In H460 and A549 cells, dose-dependent upregulation of p53 protein expression was observed in cultures treated with docetaxel alone and with docetaxel plus beta-elemene, whereas no significant change in p53 expression was observed in any of the treatment groups in H23 cells. beta-elemene 156-168 P53 Homo sapiens 55-58 17611679-11 2007 These results suggest that, although p53 plays an important role in taxane-induced cell death, apoptosis induced by beta-elemene or in combination with docetaxel thereof seems to be initiated through a p53- and Fas-independent pathway via mitochondria in our lung cancer cells. beta-elemene 116-128 P53 Homo sapiens 202-205 16950207-6 2006 Combined sulindac/ATO treatment also activated p53 expression, and inhibition of p53 expression by small interfering RNA (siRNA) prevented sulindac/ATO-induced down-regulation of survivin, suggesting that survivin expression is negatively regulated by p53. Arsenic Trioxide 18-21 P53 Homo sapiens 47-50 25737737-6 2015 Treatment of cells with pifithrin-alpha, a specific inhibitor of p53, suppressed shikonin-induced apoptosis and premature senescence, suggesting the role of p53 in mediating the actions of shikonin on regulation of lung cancer cell proliferation. pifithrin 24-39 P53 Homo sapiens 157-160 17075316-2 2006 Here, we show that p53-defective HT-29 colon cancer cells overcome methotrexate-induced cell death owing to DNA damage checkpoint-mediated cell survival at the adaptive stage that precedes stable resistance acquisition. Methotrexate 67-79 P53 Homo sapiens 19-22 17551498-5 2007 MCF-7 (oestrogen receptor (ER)+/p53 wild-type) was the most sensitive cell line to xanafide. xanafide 83-91 P53 Homo sapiens 32-35 26089934-0 2015 The Flavonoid Apigenin Ameliorates Cisplatin-Induced Nephrotoxicity through Reduction of p53 Activation and Promotion of PI3K/Akt Pathway in Human Renal Proximal Tubular Epithelial Cells. Flavonoids 4-13 P53 Homo sapiens 89-92 17096161-3 2007 We also tested whether bortezomib interactions with cytarabine and anthracyclines are affected by p53, because proteasome inhibition stabilizes p53 and may thus cause cell cycle arrest. Bortezomib 23-33 P53 Homo sapiens 98-101 17630850-5 2007 The p53 inhibitor pifithrin did not block GSNO-induced cell death. pifithrin 18-27 P53 Homo sapiens 4-7 17016641-0 2006 P53-dependent radiosensitizing effects of Hsp90 inhibitor 17-allylamino-17-demethoxygeldanamycin on human oral squamous cell carcinoma cell lines. tanespimycin 58-96 P53 Homo sapiens 0-3 17016641-9 2006 17-AAG enhanced the radiation sensitivity significantly and induced apoptosis in the SAS/neo cell which has a wild-type p53. tanespimycin 0-6 P53 Homo sapiens 120-123 17016641-10 2006 But the radiation sensitizing effect of 17-AAG was limited in the SAS/Trp248 cell which has a mutated p53. tanespimycin 40-46 P53 Homo sapiens 102-105 17030796-2 2006 The p53 binding pattern of carcinogenic polycyclic aromatic hydrocarbons (PAHs) found in CS coincides with the p53 mutational pattern found in lung cancer, and PAHs have thus been considered to be major culprits for lung cancer. Polycyclic Aromatic Hydrocarbons 40-72 P53 Homo sapiens 4-7 17456577-13 2007 Finally, when we added pifithrin-alpha, a specific inhibitor of p53 functions, a significant decrease in irradiation-induced apoptosis in both germ and Sertoli cells was observed, indicating the involvement of the p53 pathway in irradiation-induced apoptosis. pifithrin 23-38 P53 Homo sapiens 64-67 17030796-2 2006 The p53 binding pattern of carcinogenic polycyclic aromatic hydrocarbons (PAHs) found in CS coincides with the p53 mutational pattern found in lung cancer, and PAHs have thus been considered to be major culprits for lung cancer. Polycyclic Aromatic Hydrocarbons 74-78 P53 Homo sapiens 4-7 17456577-13 2007 Finally, when we added pifithrin-alpha, a specific inhibitor of p53 functions, a significant decrease in irradiation-induced apoptosis in both germ and Sertoli cells was observed, indicating the involvement of the p53 pathway in irradiation-induced apoptosis. pifithrin 23-38 P53 Homo sapiens 214-217 26374525-5 2015 However, the activation of a p63/p53-and PCNA-dependent DNA damage checkpoint, plays a major role in eliminating defective oocytes when they reach the diplotene stage. diplotene 151-160 P53 Homo sapiens 33-36 17393435-0 2007 A plant lignan, 3"-O-methyl-nordihydroguaiaretic acid, suppresses papillomavirus E6 protein function, stabilizes p53 protein, and induces apoptosis in cervical tumor cells. heminordihydroguaiaretic acid 16-53 P53 Homo sapiens 113-116 17030796-2 2006 The p53 binding pattern of carcinogenic polycyclic aromatic hydrocarbons (PAHs) found in CS coincides with the p53 mutational pattern found in lung cancer, and PAHs have thus been considered to be major culprits for lung cancer. Polycyclic Aromatic Hydrocarbons 74-78 P53 Homo sapiens 111-114 17030796-2 2006 The p53 binding pattern of carcinogenic polycyclic aromatic hydrocarbons (PAHs) found in CS coincides with the p53 mutational pattern found in lung cancer, and PAHs have thus been considered to be major culprits for lung cancer. Polycyclic Aromatic Hydrocarbons 160-164 P53 Homo sapiens 4-7 25597668-0 2015 Modulation of the DNA repair system and ATR-p53 mediated apoptosis is relevant for tributyltin-induced genotoxic effects in human hepatoma G2 cells. tributyltin 83-94 P53 Homo sapiens 44-47 17035402-7 2006 Among patients with detectable LOH at the TP53 locus (on chromosome 17p), increasing bleomycin sensitivity was associated with increased risk of developing cancer (P(trend) < 0.001) and aneuploidy (P(trend) = 0.005). Bleomycin 85-94 P53 Homo sapiens 42-46 17040108-9 2006 The cytosine residue of the ACG sequence complementary to codon 273, well-known hotspots of the p53 gene, was cleaved with piperidine and Fpg treatments. Cytosine 4-12 P53 Homo sapiens 96-99 17369602-0 2007 p-53 gene mutations as a predictive marker in a population of advanced breast cancer patients randomly treated with doxorubicin or docetaxel in the context of a phase III clinical trial. Docetaxel 131-140 P53 Homo sapiens 0-4 17504512-4 2007 The polymorphism on p53, which encodes either a proline or an arginine amino acid residue at codon 72, has been reported as a possible risk factor for cervical disease. arginine amino acid 62-81 P53 Homo sapiens 20-23 25597668-4 2015 We further demonstrated that TBT induced cell apoptosis via the p53-mediated pathway, which was most likely activated by the ataxia telangiectasia mutated and rad-3 related (ATR) protein kinase. tributyltin 29-32 P53 Homo sapiens 64-67 25597668-7 2015 Then the generated DNA damage induced by TBT initiated ATR-p53-mediated apoptosis. tributyltin 41-44 P53 Homo sapiens 59-62 25738310-12 2015 Sorafenib suppressed p53 expression at both mRNA and protein levels, which might contribute to cell cycle arrest and sensitize tumor cells to irinotecan. Sorafenib 0-9 P53 Homo sapiens 21-24 17157427-8 2007 This damage was detected as an enhanced migration of TP53 signals into the comet tail in both cell types, which indicates a high susceptibility of this tumor relevant gene towards Fe-NTA. ferric nitrilotriacetate 180-186 P53 Homo sapiens 53-57 16891316-9 2006 Based on this, we propose that a pathway composed of ATR, PML, Chk2, and p53 plays a role in ATO-mediated apoptosis, a notion that is consistent with the observation that Chk2 is genetically intact and mutations in the p53 gene are extremely rare in APL. Arsenic Trioxide 93-96 P53 Homo sapiens 73-76 16891316-9 2006 Based on this, we propose that a pathway composed of ATR, PML, Chk2, and p53 plays a role in ATO-mediated apoptosis, a notion that is consistent with the observation that Chk2 is genetically intact and mutations in the p53 gene are extremely rare in APL. Arsenic Trioxide 93-96 P53 Homo sapiens 219-222 17157427-9 2007 In conclusion, Fe-NTA acts genotoxic in non-transformed and in preneoplastic human colon cells, in which it also enhances migration of TP53 at relatively low concentrations. ferric nitrilotriacetate 15-21 P53 Homo sapiens 135-139 25435953-15 2015 Subsequent to the use of Pifithrin-alpha, a specific inhibitor of p53 activation, increased MDM2 expression was observed in the LIRR1-overexpressing cells, suggesting that LIRR1 could mediate the DNA damage response (DDR) signaling in a p53-dependent manner. pifithrin 25-40 P53 Homo sapiens 66-69 17230520-2 2007 Earlier studies have shown that selenite induces DNA single strand breaks (SSBs), reactive oxygen species (ROS), p53 Ser-15 phosphorylation and caspase-dependent and -independent apoptosis, whereas a methylselenol precursor methylseleninic acid (MSeA) induces caspase-mediated apoptosis regardless of p53 status. methaneselenol 200-213 P53 Homo sapiens 301-304 20641411-10 2004 showed that the binding of resveratrol to integrin alphaVss3, principally to the ss3 monomer, was essential for transduction of the stilbene signal into p53-dependent apoptosis of breast cancer cells. Stilbenes 132-140 P53 Homo sapiens 153-156 25435953-15 2015 Subsequent to the use of Pifithrin-alpha, a specific inhibitor of p53 activation, increased MDM2 expression was observed in the LIRR1-overexpressing cells, suggesting that LIRR1 could mediate the DNA damage response (DDR) signaling in a p53-dependent manner. pifithrin 25-40 P53 Homo sapiens 237-240 16720286-9 2006 The three retinoids differentially affected p53, RARs, and JWA. Retinoids 10-19 P53 Homo sapiens 44-47 25510742-8 2015 RESULTS: Anthocyanin treatment of DU-145 cells resulted in 1) significant increase in apoptosis in a dose-dependent manner, 2) significant decrease in p53 and Bcl-2 expressions (with increased Bax expression), and 3) significant decrease in PSA and AR expressions. du 34-36 P53 Homo sapiens 151-154 16720314-7 2006 In all cell lines, quercetin decreased the expression of mutant P53 and Survivin proteins. Quercetin 19-28 P53 Homo sapiens 64-67 16720314-11 2006 Quercetin-induced apoptosis might be associated with a decrease in mutant P53 and Survivin proteins. Quercetin 0-9 P53 Homo sapiens 74-77 25523932-17 2014 CONCLUSIONS: HATi II inhibits proliferation and induces apoptosis via the caspase-dependent pathway in human glioma cell lines, possibly by activating the p53 signaling pathway. hati ii 13-20 P53 Homo sapiens 155-158 16948901-6 2006 Expression of P53 and C-myc protein decreased following quercetin induction in a dose-dependent manner, whereas P16 expression increased significantly compared with that of the control group (P<0.01). Quercetin 56-65 P53 Homo sapiens 14-17 16632641-9 2006 SP600125 (anthra [1,9-cd]pyrazol-6(2H)-one-1,9-pyrazoloanthrone), a specific inhibitor of JNK, significantly decreased apoptosis by inhibiting the phosphorylation of p53 (serine 15) and subsequently increased the interaction of p53 and MDM2. pyrazolanthrone 0-8 P53 Homo sapiens 166-169 25565771-9 2015 Pifithrin-alpha, a p53 inhibitor, blocked the modulation of As4S4 on AGS cells, but not on MGC803 cells. pifithrin 0-15 P53 Homo sapiens 19-22 16632641-9 2006 SP600125 (anthra [1,9-cd]pyrazol-6(2H)-one-1,9-pyrazoloanthrone), a specific inhibitor of JNK, significantly decreased apoptosis by inhibiting the phosphorylation of p53 (serine 15) and subsequently increased the interaction of p53 and MDM2. pyrazolanthrone 0-8 P53 Homo sapiens 228-231 16500682-6 2006 Treatment with sulforaphane (15 microM), PEITC (10 microM), indole-3-carbinol (10 microM) and 3,3"-diindolylmethane (10 microM) induced PARP cleavage after 24 and 48 h in both 40-16 and the 379.2 cell lines, suggestive of a p53-independent mechanism of apoptosis induction. sulforaphane 15-27 P53 Homo sapiens 224-227 16500682-10 2006 Taken together, we demonstrated that the glucosinolate breakdown products investigated in this study have distinct profiles of cell growth inhibition, potential to induce p53-independent apoptosis and to modulate Bcl-2 family protein expression in human colon cancer cell lines. Glucosinolates 41-54 P53 Homo sapiens 171-174 16714289-10 2006 PGE(2), overexpression of p53wt with PGE(2), or p53S15E abolished the MEKK1-induced MMP-1 promoter luciferase activity. Prostaglandins E 37-40 P53 Homo sapiens 26-29 25495224-3 2014 RESULTS: The effect of IL-1beta, but not of TNF-alpha, on glutamate-mediated excitatory postsynaptic currents was blocked by pifithrin-alpha (PFT), inhibitor of p53. pifithrin 125-140 P53 Homo sapiens 161-164 26579413-0 2014 ETME, a novel beta-elemene derivative, synergizes with arsenic trioxide in inducing apoptosis and cell cycle arrest in hepatocarcinoma cells via a p53-dependent pathway. Arsenic Trioxide 55-71 P53 Homo sapiens 147-150 16765943-4 2006 Moreover, Western blot studies showed that (R)-roscovitine increased nutlin-3-mediated p53 stabilization. Roscovitine 43-58 P53 Homo sapiens 87-90 16765943-5 2006 Therefore, we conclude the contribution of (R)-roscovitine to the synergism is basically the sensitization of SH-SY5Y cells to the action of nutlin-3 on p53. Roscovitine 43-58 P53 Homo sapiens 153-156 16533604-3 2006 ET-743, a DNA minor groove binder, which blocks cell cycle progression in G2/M phase through a p53-independent apoptotic process, represents the most promising among novel compounds in STS, since recently completed phase II trials have consistently shown high survival, in spite of the relatively low incidence of major objective responses. Trabectedin 0-6 P53 Homo sapiens 95-98 26579413-5 2014 The combination also decreased the MMP, down-regulated Bcl-2 and pro-proteins of the caspase family, and up-regulated Bax and BID, all of which were reversed by the p53 inhibitor, pifithrin-alpha. pifithrin 180-189 P53 Homo sapiens 165-168 25412312-7 2014 On the other hand, when human colorectal cancer HCT-116 cells with wild-type p53 were treated with BITC, translocation of p65 to the nucleus was inhibited rather than enhanced. benzyl isothiocyanate 99-103 P53 Homo sapiens 77-80 16735036-1 2006 Exposure of Jurkat T lymphocytes containing functional p53 to nanomolar concentrations of bisanthracycline WP631 resulted in arrest at the G2/M checkpoint and transient senescence-like phenotype in the presence of DNA synthesis. bisanthracycline 90-106 P53 Homo sapiens 55-58 25098371-0 2014 L-Leucine improves the anaemia in models of Diamond Blackfan anaemia and the 5q- syndrome in a TP53-independent way. Leucine 0-9 P53 Homo sapiens 95-99 25204604-0 2014 beta-Elemene against human lung cancer via up-regulation of P53 protein expression to promote the release of exosome. beta-elemene 0-12 P53 Homo sapiens 60-63 16574813-8 2006 On the contrary, suppression of PTEN levels by RNA interference restores the enhanced expression of p53-dependent p21(WAF1) and p53-independent p27(kip1) through inactivating the effect of PTEN on PI-3K/AKT signaling modulated by ganglioside GM3. Gangliosides 230-241 P53 Homo sapiens 100-103 16574813-8 2006 On the contrary, suppression of PTEN levels by RNA interference restores the enhanced expression of p53-dependent p21(WAF1) and p53-independent p27(kip1) through inactivating the effect of PTEN on PI-3K/AKT signaling modulated by ganglioside GM3. Gangliosides 230-241 P53 Homo sapiens 128-131 16467208-6 2006 High doses of ATO induced p53 accumulation in 11 of 21 patients. Arsenic Trioxide 14-17 P53 Homo sapiens 26-29 25204604-11 2014 The levels of the anti-apoptotic genes Bcl-2 and Bcl-xl in A549 cells decreased, while expression of P53 and production of exosomes increased after beta-elemene treatment. beta-elemene 148-160 P53 Homo sapiens 101-104 16288207-9 2006 Pretreatment with the specific p53 inhibitor pifithrin or downregulation of p53 using a specific small inhibitory RNA significantly attenuated ODQ-induced apoptosis. pifithrin 45-54 P53 Homo sapiens 31-34 25204604-12 2014 Further siRNA studies suggested that the effect of beta-elemene on A549 cells is dependent on P53 expression. beta-elemene 51-63 P53 Homo sapiens 94-97 25204604-14 2014 The in vivo study demonstrated that beta-elemene inhibited tumor growth, and up-regulated the expression of P53 and the release of exosome. beta-elemene 36-48 P53 Homo sapiens 108-111 16525665-9 2006 DHPLC demonstrated that 37.5% (3/8) of esophageal carcinomas and 44.4% (4/9) of gastric carcinomas have p53 mutations. dhplc 0-5 P53 Homo sapiens 104-107 25204604-15 2014 CONCLUSION: Our results demonstrated beta-elemene acts on lung cancer cells in a P53 dependent manner and exosomes are involved in the regulation of cell proliferation. beta-elemene 37-49 P53 Homo sapiens 81-84 24928376-9 2014 Quercetin also could increase p53 and Caspase-3 expression. Quercetin 0-9 P53 Homo sapiens 30-33 16436374-3 2006 Mammalian cells contain three non-identical subunits of RNR; that is, one homodimeric large subunit, R1, carrying the catalytic site and two variants of the homodimeric small subunit, R2 and the p53-inducible p53R2, each containing a tyrosyl free radical essential for catalysis. tyrosyl free radical 234-254 P53 Homo sapiens 195-198 24786831-4 2014 PELP1 is phosphorylated at Serine1033 by various DDR kinases like ataxia-telangiectasia mutated, ataxia telangiectasia and Rad3-related or DNAPKc and this phosphorylation of PELP1 is important for p53 coactivation functions. serine1033 27-37 P53 Homo sapiens 197-200 16319070-7 2006 Furthermore, troglitazone induced Ser-392 phosphorylation of p53 via a PPARgamma-dependent pathway and up-regulation of Bax in a p53 wild-type glioma. Troglitazone 13-25 P53 Homo sapiens 61-64 16319070-7 2006 Furthermore, troglitazone induced Ser-392 phosphorylation of p53 via a PPARgamma-dependent pathway and up-regulation of Bax in a p53 wild-type glioma.

Bleomycin 125-134 P53 Homo sapiens 73-76 24927258-0 2014 Increased growth-inhibitory and cytotoxic activity of arsenic trioxide in head and neck carcinoma cells with functional p53 deficiency and resistance to EGFR blockade. Arsenic Trioxide 54-70 P53 Homo sapiens 120-123 16139849-11 2006 In conclusion, our data show that loss of MMR and p53 function exerts opposite and independent effects on apoptosis and chromosomal damage induced by bleomycin. Bleomycin 150-159 P53 Homo sapiens 50-53 16170570-0 2006 p53-independent G1 cell cycle arrest of human colon carcinoma cells HT-29 by sulforaphane is associated with induction of p21CIP1 and inhibition of expression of cyclin D1. sulforaphane 77-89 P53 Homo sapiens 0-3 24927258-4 2014 The causal relationship between p53 deficiency and ATO sensitivity was evaluated by reconstitution of wildtype p53 in p53-deficient SCCHN cells.

Arsenic Trioxide 51-54 P53 Homo sapiens 111-114 24927258-6 2014 RESULTS: Functional rather than structural defects in the p53 gene predisposed tumor cells to increased sensitivity to ATO. Arsenic Trioxide 119-122 P53 Homo sapiens 58-61 24927258-7 2014 Reconstitution of wt p53 in p53-deficient SCCHN cells rendered them less sensitive to ATO treatment. Arsenic Trioxide 86-89 P53 Homo sapiens 21-24 24927258-7 2014 Reconstitution of wt p53 in p53-deficient SCCHN cells rendered them less sensitive to ATO treatment. Arsenic Trioxide 86-89 P53 Homo sapiens 28-31 24927258-9 2014 The inhibitory effect of ATO in p53-deficient tumor cells was mainly associated with DNA damage, G2/M arrest, upregulation of TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) receptors and apoptosis. Arsenic Trioxide 25-28 P53 Homo sapiens 32-35 16505115-2 2006 However, it is also known that nucleosides are efficient activators of apoptosis in tumor cells that do not express a functional p53. Nucleosides 31-42 P53 Homo sapiens 129-132 24927258-11 2014 CONCLUSIONS: Addition of ATO to treatment regimens for p53-deficient SCCHN and tumor recurrence after cetuximab-containing regimens might represent an attractive strategy in SCCHN. Arsenic Trioxide 25-28 P53 Homo sapiens 55-58 16505115-11 2006 Together, these studies indicate that c-Abl-independent p73 stabilization pathways could account for the p53-independent mechanisms in nucleoside-induced apoptosis. Nucleosides 135-145 P53 Homo sapiens 105-108 24841907-6 2014 Moreover, the p53 inhibitor pifithrin-alpha and the nuclear factor (NF)-kappaB inhibitor pyrrolidinedithiocarbamic acid (PDTC) clearly suppressed Beclin-1 and LC3-II and increased cytochrome c release, caspase-3 activation, and PARP cleavage. pifithrin 28-37 P53 Homo sapiens 14-17 16582987-2 2006 We studied sequence-specific interaction of the vinyl-chloride metabolite CAA with human p53 gene exons 5-8, using DNA Polymerase Fingerprint Analysis (DPFA), and identified sites of the highest sensitivity. chloroacetaldehyde 74-77 P53 Homo sapiens 89-92 16582987-3 2006 CAA-induced DNA damage was more extensive in p53 regions which revealed secondary structure perturbations, and were localized in regions of mutation hot-spots. chloroacetaldehyde 0-3 P53 Homo sapiens 45-48 16582987-6 2006 A plasmid bearing full length cDNA of human p53 gene was modified in vitro with 360 mM CAA and transformed into E. coli DH5alpha strain, in which the adaptive response system had been induced by MMS treatment before the cells were made competent. chloroacetaldehyde 87-90 P53 Homo sapiens 44-47 24736433-5 2014 The main objective of this study was to determine whether p53 modulated AhR-dependent gene expression and PAH metabolism. Polycyclic Aromatic Hydrocarbons 106-109 P53 Homo sapiens 58-61 24736433-13 2014 Collectively, our results suggest that p53 affects AhR-dependent gene expression, PAH metabolism, and possibly carcinogenesis. Polycyclic Aromatic Hydrocarbons 82-85 P53 Homo sapiens 39-42 24694947-11 2014 Our data show olaparib and veliparib differ in their off-target effects; olaparib, unlike veliparib, mitigates DNA damage repair activity via G(2) cell-cycle arrest-like effect in a p53-dependent manner. veliparib 27-36 P53 Homo sapiens 182-185 24878898-8 2014 Phosphorylation of AMPK, ULK, JNK, c-jun, and p53 was increased significantly in response to KIOM-C treatment. kiom-c 93-99 P53 Homo sapiens 46-49 24089038-4 2014 Following ex vivo treatment with melphalan, a gradual suppression of the apoptotic pathway occurred in samples collected at different stages of myelomagenesis, with the severity and duration of the inhibition of RNA synthesis, p53 phosphorylation at serine15 and induction of apoptosis being higher in MGUS than SMM and lowest in MM patients (all P<0.0103). Melphalan 33-42 P53 Homo sapiens 227-230 24462521-11 2014 Our results collectively demonstrate that TP53-correlated kinase MPS1, is a potential therapeutic target in BC patients with TP53 mutated tumors, and that SP600125 warrant further development in future clinical trials. pyrazolanthrone 155-163 P53 Homo sapiens 42-46 24743574-12 2014 Moreover, Bcl-2 expression was completely reversed by treatment with pifithrin-alpha, a p53-specific inhibitor. pifithrin 69-84 P53 Homo sapiens 88-91 24601644-0 2014 Novel inhibitors of the MDM2-p53 interaction featuring hydrogen bond acceptors as carboxylic acid isosteres. carboxylic acid isosteres 82-107 P53 Homo sapiens 29-32 25237368-0 2014 Effect of boswellia thurifera gum methanol extract on cytotoxicity and p53 gene expression in human breast cancer cell line.

Methanol 133-141 P53 Homo sapiens 223-226 25237368-10 2014 The increase of P53 gene specific mRNA may be a mechanism of gum methanol extract induced cytotoxicity. Methanol 65-73 P53 Homo sapiens 16-19 24736075-3 2014 As dexamethasone strongly regulates many genes including p53 through the glucocorticoid receptor (GR), we hypothesized that dexamethasone influences tumor response to pemetrexed. Pemetrexed 167-177 P53 Homo sapiens 57-60 24405416-4 2014 Herein we report the design, synthesis and optimization of YH239-EE (ethyl ester of the free carboxylic acid compound YH239), a potent p53-MDM2 antagonizing and apoptosis-inducing agent characterized by a number of leukemia cell lines as well as patient-derived AML blast samples. ethyl ester 69-80 P53 Homo sapiens 135-138 24576095-1 2014 TIGAR [TP53 (tumour protein 53)-induced glycolysis and apoptosis regulator] protein is known for its ability to inhibit glycolysis, shifting glucose consumption towards the pentose phosphate pathway to promote antioxidant protection of cancer cells.

Docetaxel 125-134 P53 Homo sapiens 75-78 16170329-4 2005 Jasmonic acid and methyl jasmonate (0.25-3 mM) were each equally cytotoxic to both clones, whereas mutant p53-expressing cells were resistant to treatment with the radiomimetic agent neocarzinostatin and the chemotherapeutic agent bleomycin. Bleomycin 231-240 P53 Homo sapiens 106-109 16582595-5 2006 A similar differential effect of these retinoids was observed for the induction of p53, which has been reported to regulate GDF-15 expression. Retinoids 39-48 P53 Homo sapiens 83-86 16170329-5 2005 Neocarzinostatin and bleomycin induced an elevation in the p53 levels in wt p53-expressing cells, whereas methyl jasmonate did not.

Flavonoids 4-14 P53 Homo sapiens 167-174 16391851-8 2006 While TUNEL-positive cells and p53 immunoreactivity were detected in Docetaxel, Doxorubicin and Docetaxel/Doxorubicin groups, p53 immunoreactivity was not observed in the Docetaxel group. Docetaxel 69-78 P53 Homo sapiens 31-34 16391851-8 2006 While TUNEL-positive cells and p53 immunoreactivity were detected in Docetaxel, Doxorubicin and Docetaxel/Doxorubicin groups, p53 immunoreactivity was not observed in the Docetaxel group. Docetaxel 96-105 P53 Homo sapiens 31-34 16391851-8 2006 While TUNEL-positive cells and p53 immunoreactivity were detected in Docetaxel, Doxorubicin and Docetaxel/Doxorubicin groups, p53 immunoreactivity was not observed in the Docetaxel group. Docetaxel 96-105 P53 Homo sapiens 31-34 16391851-13 2006 These findings suggest that the possible mechanism of cell death in Doxorubicin and Docetaxel/Doxorubicin treatment groups is related to apoptosis through the p53 pathway.

Troglitazone 9-21 P53 Homo sapiens 35-38 16303758-7 2006 Further, troglitazone also induced p53 protein expression in HCT116 cells, which may be the possible mechanism for PPARgamma-independent POX activation, since POX has been shown to be a downstream mediator in p53-induced apoptosis. Troglitazone 9-21 P53 Homo sapiens 209-212 23356739-12 2013 In addition to its effects on histone modifications, garcinol was found to block CBP/p300-mediated acetylation of the C-terminal activation domain of p53, but resulted in enhanced acetylation of p53K120, and accumulation of p53 in the cytoplasmic compartment. garcinol 53-61 P53 Homo sapiens 195-198 23356739-15 2013 Garcinol treatment alters expression of chromatin modifying enzymes in MCF7 cells, resulting in reprogramming of key histone and p53 PTMs and growth arrest, underscoring its potential as a cancer chemopreventive agent. garcinol 0-8 P53 Homo sapiens 129-132 23244159-0 2013 Electrochemical study on the effects of epigenetic cytosine methylation on anti-benzo[a]pyrene diol epoxide damage at TP53 oligomers.

Arsenic Trioxide 33-49 P53 Homo sapiens 61-64 22387547-8 2012 However, the inhibition of P53 by Pifithrin-alpha abolished the above-mentioned effects of XPD. pifithrin 34-43 P53 Homo sapiens 27-30 15637397-5 2005 Retinoid-oral IEN studies (eg, of retinoic acid receptor-beta, p53, genetic instability, loss of heterozygosity, and cyclin D1) have advanced the overall understanding of the biology of intraepithelial carcinogenesis and of preventive agent molecular mechanisms and targets-important advances for monitoring preventive interventions and assessing cancer risk and pharmacogenomics. Retinoids 0-8 P53 Homo sapiens 63-66 22425996-6 2012 Our studies demonstrate that concomitant loss of either p53 (also known as Tp53) or Lkb1 (also known as Stk11), two clinically relevant tumour suppressors, markedly impaired the response of Kras-mutant cancers to docetaxel monotherapy. Docetaxel 213-222 P53 Homo sapiens 56-59 16122187-1 2005 PURPOSE: In this study the relationship between therapy with paclitaxel, cisplatin, vinorelbine and titanocene dichloride and of the expression of proliferation markers (ki67 and S-phase fraction) and tumour suppressor gene p53 was analyzed using a human ovarian cancer xenograft model. Vinorelbine 84-95 P53 Homo sapiens 224-227 16122187-9 2005 The vinorelbine-group had the highest percentage of p53-positive specimens (60%), in both titanocene-groups no specimen showed a positive staining for p53 and in the control group 7.1% of the specimens were positively stained for p53. Vinorelbine 4-15 P53 Homo sapiens 52-55 15869405-4 2005 However, addition of ethidium homodimer-1 and Annexin-V-FITC post-pulse demonstrated greater fluorescence in p53-/- versus p53+/+ cells, suggesting a postpulse p53-dependent biological effect at the plasma membrane. Ethidium 21-29 P53 Homo sapiens 109-112 15869405-4 2005 However, addition of ethidium homodimer-1 and Annexin-V-FITC post-pulse demonstrated greater fluorescence in p53-/- versus p53+/+ cells, suggesting a postpulse p53-dependent biological effect at the plasma membrane. Ethidium 21-29 P53 Homo sapiens 123-126 15869405-4 2005 However, addition of ethidium homodimer-1 and Annexin-V-FITC post-pulse demonstrated greater fluorescence in p53-/- versus p53+/+ cells, suggesting a postpulse p53-dependent biological effect at the plasma membrane.

Nucleosides 12-22 P53 Homo sapiens 43-46 15793143-1 2005 We investigated the ability of p53 in cytoplasm to excise nucleoside analogs (NAs). Nucleosides 58-68 P53 Homo sapiens 31-34 22425996-6 2012 Our studies demonstrate that concomitant loss of either p53 (also known as Tp53) or Lkb1 (also known as Stk11), two clinically relevant tumour suppressors, markedly impaired the response of Kras-mutant cancers to docetaxel monotherapy. Docetaxel 213-222 P53 Homo sapiens 75-79 15793143-2 2005 A decrease in incorporation of NAs by human immunodeficiency virus type 1 reverse transcriptase and their excision from DNA by p53, provided by the cytoplasmic fraction of LCC2 cells, suggest that p53 in cytoplasm may act as an external proofreader for NA incorporation. Nucleosides 31-34 P53 Homo sapiens 197-200 15331571-6 2004 Treatment of nonluteinized macaque granulosa cells with hCG and the p53 inhibitor pifithrin-alpha (PFT) in vitro did not alter markers of the cell cycle, including proliferating cell nuclear antigen, p21, and human double minute (HDM)-2 expression compared with hCG alone. pifithrin 82-97 P53 Homo sapiens 68-71 22200537-0 2012 Liposomal formulations of Etoposide and Docetaxel for p53 mediated enhanced cytotoxicity in lung cancer cell lines. Docetaxel 40-49 P53 Homo sapiens 54-57 15648263-0 2004 Marine alkaloid polycarpine and its synthetic derivative dimethylpolycarpine induce apoptosis in JB6 cells through p53- and caspase 3-dependent pathways. Alkaloids 7-15 P53 Homo sapiens 115-118 22200537-1 2012 The objective of present investigation was to develop and assess comparative enhancement in cytotoxicity of liposomal Etoposide and Docetaxel in non-small cell lung cancer cell lines after pre-treatment and co-administration of p53 tumor suppressor gene and to assess direct lung targeting of optimized formulations by dry powder inhaler technology. Docetaxel 132-141 P53 Homo sapiens 228-231 15648263-0 2004 Marine alkaloid polycarpine and its synthetic derivative dimethylpolycarpine induce apoptosis in JB6 cells through p53- and caspase 3-dependent pathways. dimethylpolycarpine 57-76 P53 Homo sapiens 115-118 15523690-0 2005 DHPLC is superior to SSCP in screening p53 mutations in esophageal cancer tissues. dhplc 0-5 P53 Homo sapiens 39-42 15523690-8 2005 Thus, rates of p53 mutations and polymorphisms in esophageal cancer tissue in Chinese patients were 49% and 41% by DHPLC and SSCP, respectively. dhplc 115-120 P53 Homo sapiens 15-18 16335246-3 2005 An increase in p53 protein expression was found in A549 and MCF7 (WT) cells treated with cisplatin, methotrexate, and doxorubicin, whereas the level of p53 was not statistically significantly changed in the MCF7 DOX/R cells. Methotrexate 100-112 P53 Homo sapiens 15-18 22223137-0 2012 Upregulated p53 expression activates apoptotic pathways in wild-type p53-bearing mesothelioma and enhances cytotoxicity of cisplatin and pemetrexed. Pemetrexed 137-147 P53 Homo sapiens 12-15 15547111-11 2005 Our data demonstrate that 5-aza-CR action in HCT-116 is mediated by p53 and its downstream effectors p21(WAF1) and GADD45. Azacitidine 26-34 P53 Homo sapiens 68-71 15378026-7 2004 Activation of endogenous wt p53 in BLs and lymphoblastoid cell lines led to the induction of SAP and this was inhibited by the specific p53 inhibitor pifithrin-alpha. pifithrin 150-165 P53 Homo sapiens 28-31 15378026-7 2004 Activation of endogenous wt p53 in BLs and lymphoblastoid cell lines led to the induction of SAP and this was inhibited by the specific p53 inhibitor pifithrin-alpha. pifithrin 150-165 P53 Homo sapiens 136-139 22223137-2 2012 We examined whether forced expression of p53 inhibited growth of mesothelioma cells and produced anti-tumor effects by a combination of cisplatin (CDDP) or pemetrexed (PEM), the first-line drugs for mesothelioma treatments. Pemetrexed 156-166 P53 Homo sapiens 41-44 22283740-10 2012 Activation of p53 was suppressed by SP600125 and expression of p-JNK was inhibited by PFT-alpha, therefore silibinin might activate a ROS-JNK-p53 cycle to induce cell death. pyrazolanthrone 36-44 P53 Homo sapiens 14-17 15382061-4 2004 PARP cleavage and a decrease in S+G2 cells were evident after RuCl2(KTZ)2 treatment in genetically matched C8161 melanoma monolayers with unequal p53 functional status. Ketoconazole 68-71 P53 Homo sapiens 146-149 15505427-0 2004 Sensitization by glycerol for CDDP-therapy against human cultured cancer cells and tumors bearing mutated p53 gene. Glycerol 17-25 P53 Homo sapiens 106-109 15607904-4 2005 SK-N-BE human neuroblastoma cells express the three p53 family proteins and can be used for the study of their induction. sk-n 0-4 P53 Homo sapiens 52-55 15607904-11 2005 Our results demonstrated that HNE inhibits SK-N-BE cell proliferation by increasing the expression of p53 family proteins and p53 target proteins which modulate cell cycle progression and apoptosis. sk-n 43-47 P53 Homo sapiens 102-105 15505427-3 2004 When those cultured cells were pre-treated with glycerol, CDDP-induced apoptosis was enhanced by glycerol in SAS/m p53 cells but not in SAS/ neo cells. Glycerol 48-56 P53 Homo sapiens 115-118 15607904-11 2005 Our results demonstrated that HNE inhibits SK-N-BE cell proliferation by increasing the expression of p53 family proteins and p53 target proteins which modulate cell cycle progression and apoptosis. sk-n 43-47 P53 Homo sapiens 126-129 15505427-3 2004 When those cultured cells were pre-treated with glycerol, CDDP-induced apoptosis was enhanced by glycerol in SAS/m p53 cells but not in SAS/ neo cells. Glycerol 97-105 P53 Homo sapiens 115-118 22301190-8 2012 In summary, we suggest that p53 has a novel function in regulating purine biosynthesis, aided by miR-34a-dependent IMPDH repression. purine 67-73 P53 Homo sapiens 28-31 15492510-7 2004 Phosphatidylinositol-3 kinase-like protein kinases (ATR and also ATM) -dependent phosphorylation of p53-Ser15 residue was associated with the accumulation of p53, and stimulation of p21(Waf-1) and GADD45, resulting in G(2)/M delay in BCR/ABL cells after genotoxic treatment. gadd45 197-203 P53 Homo sapiens 100-103 15492510-7 2004 Phosphatidylinositol-3 kinase-like protein kinases (ATR and also ATM) -dependent phosphorylation of p53-Ser15 residue was associated with the accumulation of p53, and stimulation of p21(Waf-1) and GADD45, resulting in G(2)/M delay in BCR/ABL cells after genotoxic treatment. gadd45 197-203 P53 Homo sapiens 158-161 15685439-12 2005 TP53 mutations are significantly more frequent in low-grade astrocytomas with promoter methylation of the O(6)-methylguanine-DNA methyltransferase repair gene, suggesting that, in addition to deamination of 5-methylcytosine, exogenous or endogenous alkylation in the O(6) position of guanine may contribute to the formation of these mutations. 5-Methylcytosine 207-223 P53 Homo sapiens 0-4 15685439-12 2005 TP53 mutations are significantly more frequent in low-grade astrocytomas with promoter methylation of the O(6)-methylguanine-DNA methyltransferase repair gene, suggesting that, in addition to deamination of 5-methylcytosine, exogenous or endogenous alkylation in the O(6) position of guanine may contribute to the formation of these mutations. Guanine 117-124 P53 Homo sapiens 0-4 22399804-8 2012 Consistent with a role for p53 in cell death in interphase, depletion of p53 renders cells less sensitive to vinorelbine, but only in the presence of wild-type APC. Vinorelbine 109-120 P53 Homo sapiens 73-76 15642191-2 2005 This study was to observe the abrogation of radiation-induced G(2) phase arrest of p53 mutated human cancer cell lines by 7-hydroxystaurosporine (UCN-01), and explore the mechanism. 7-hydroxystaurosporine 122-144 P53 Homo sapiens 83-86 15931363-6 2004 Retinoid-oral IEN studies (e.g., retinoid acid receptor-beta, p53, genetic instability, loss of heterozygosity, and cyclin D1) have advanced the overall understanding of the biology of intraepithelial carcinogenesis and preventive agent molecular mechanisms and targets, important advances for monitoring preventive interventions, assessing cancer risk, and pharmacogenomics. Retinoids 0-8 P53 Homo sapiens 62-65 22184125-5 2012 We demonstrate that N1 also lowers toxicity, cell death, and p53 pathway exacerbation triggered by Swedish mutated betaAPP overexpression in human cells. 4-(2-(4-isopropylbenzamido)ethoxy)benzoic acid 20-22 P53 Homo sapiens 61-64 15501776-0 2004 Role of protein tyrosine kinase p53/56lyn in diminished lipopolysaccharide priming of formylmethionylleucyl- phenylalanine-induced superoxide production in human newborn neutrophils.

Bortezomib 21-31 P53 Homo sapiens 132-135 21607615-2 2012 A guanine (G)/cytosine (C) common single nucleotide polymorphism (SNP) at second position of codon 72 in exon 4 of p53 gene determines a arginine (Arg) to proline (Pro) (Arg72Pro) aminoacidic substitution within the proline-rich domain of p53 protein. Cytosine 14-22 P53 Homo sapiens 239-242 22213289-6 2012 In p53-null cells, the combination of low dose 5-FU with up to 6 muM quercetin promoted clonogenic survival. Quercetin 69-78 P53 Homo sapiens 3-6 16190549-8 2005 CONCLUSIONS: Tissue p53 protein expression increase and bcl-2 decrease can be a prognostic marker as far as a positive effect of IFNa2b+RBV treatment and HCV elimination are concerned. Ribavirin 136-139 P53 Homo sapiens 20-23 15308759-8 2004 The level of initially formed DNA adducts needed to cause elevation of p53 from a baseline level of 0.5 ng/mg total protein to 2 ng/mg was 5- to 8-fold higher for monohydroxymelphalan than melphalan. Melphalan 174-183 P53 Homo sapiens 71-74 15361831-9 2004 The caspase inhibitor, Z-VAD-FMK, blocked the decrease in Mdm2 as well as the increase in p53 resulting from Survivin disruption, indicating that Survivin regulates Mdm2 at the post-translational level. benzyloxycarbonylvalyl-alanyl-aspartyl fluoromethyl ketone 23-32 P53 Homo sapiens 90-93 15456784-0 2004 Survivin and p53 modulate quercetin-induced cell growth inhibition and apoptosis in human lung carcinoma cells. Quercetin 26-35 P53 Homo sapiens 13-16 15456784-2 2004 However, the regulation of survivin and p53 on the quercetin-induced cell growth inhibition and apoptosis in cancer cells remains unclear. Quercetin 51-60 P53 Homo sapiens 40-43 22213289-7 2012 Treatment of p53-wild-type cells with 50 muM quercetin reduced drug-induced up-regulation of p53, p21 and BAX. Quercetin 45-54 P53 Homo sapiens 13-16 15456784-3 2004 In this study, we investigated the roles of survivin and p53 in the quercetin-treated human lung carcinoma cells.

Isothiocyanates 74-89 P53 Homo sapiens 109-112 15456784-9 2004 Subsequently, quercetin increased the levels of total p53 (DO-1), phospho-p53 (serine 15), and p21 proteins, which were translocated to the nuclei in A549 cells. Quercetin 14-23 P53 Homo sapiens 54-57 22213289-7 2012 Treatment of p53-wild-type cells with 50 muM quercetin reduced drug-induced up-regulation of p53, p21 and BAX. Quercetin 45-54 P53 Homo sapiens 93-96 15456784-9 2004 Subsequently, quercetin increased the levels of total p53 (DO-1), phospho-p53 (serine 15), and p21 proteins, which were translocated to the nuclei in A549 cells. Quercetin 14-23 P53 Homo sapiens 74-77 15498930-8 2004 Furthermore, the low-dose hypersensitivity and Annexin V binding to irradiated A549 and T98G cells were eliminated by treating the cells with pifithrin, an inhibitor of p53. pifithrin 142-151 P53 Homo sapiens 169-172 15456784-10 2004 Treatment with a specific p53 inhibitor, pifithrin-alpha, or transfection of a p53 antisense oligodeoxynucleotide enhanced the cytotoxicity of the quercetin-treated cells. Quercetin 147-156 P53 Homo sapiens 26-29 22213289-9 2012 CONCLUSION: While high doses of quercetin synergize with DNA-damaging agents, the effect of drug combination with quercetin is influenced by the effective doses and the p53 status of the cells. Quercetin 114-123 P53 Homo sapiens 169-172 15456784-10 2004 Treatment with a specific p53 inhibitor, pifithrin-alpha, or transfection of a p53 antisense oligodeoxynucleotide enhanced the cytotoxicity of the quercetin-treated cells. Quercetin 147-156 P53 Homo sapiens 79-82 22901138-2 2012 METHODS: Stool DNA was isolated and tumor-associated high molecular weight DNA (1.476 kb fragment including exons 6-9 of the p53 gene) was amplified using PCR and visualized on ethidium bromide-stained agarose gels. Ethidium 177-193 P53 Homo sapiens 125-128 15456784-12 2004 Together, our results suggest that survivin can reduce the cell growth inhibition and apoptosis, and p53 elevates the p21 level, which may attenuate the cell death in the quercetin-treated human lung carcinoma cells. Quercetin 171-180 P53 Homo sapiens 101-104 15665582-4 2004 There are evidences to suggest that the base excision repair (BER) induced by the base-damaging agent methyl methanesulfonate (MMS) is partially deficient in cells lacking functional p53. Methyl Methanesulfonate 102-125 P53 Homo sapiens 183-186 15544062-10 2004 HEM 25 microM and 30 microM significantly increased P53 protein expression 2.3-3.6-fold in SMMC-7721 and 3.0-5.7- fold in HO-8910 cells. smmc 91-95 P53 Homo sapiens 52-55 15665582-4 2004 There are evidences to suggest that the base excision repair (BER) induced by the base-damaging agent methyl methanesulfonate (MMS) is partially deficient in cells lacking functional p53. Methyl Methanesulfonate 127-130 P53 Homo sapiens 183-186 22415097-6 2012 The SKLB70359 induced G0/G1 cell cycle arrest was characterized by down-regulation of cyclin-dependent kinase 2 (CDK2), CDK4, CDK6 expression and up-regulation of p53, p21(WAF1). 3-amino-6-(3,4-dichlorophenyl)thieno(2,3-b)pyridine-2-carboxamide 4-13 P53 Homo sapiens 163-166 15638966-3 2004 Bortezomib targets pathways relevant to tumor progression and therapy resistance and can directly modulate expression of cyclins, p27kip1, p53, nuclear factor-kB, Bcl-2, and Bax.

Ketoconazole 207-210 P53 Homo sapiens 138-141 15239130-3 2004 For immunohistochemical analysis of p53 protein expression, we introduced tyramide signal amplification immunohistochemistry (TSA-IHC) on a tissue microarray. tyramide 74-82 P53 Homo sapiens 36-39 15302096-7 2004 Pifithrin-alpha, a chemical inhibitor of wild-type p53, ameliorated the cytotoxicity of Ara-C in NALM-6 and MOLT-4, but not Jurkat, U937 or HL-60. pifithrin 0-15 P53 Homo sapiens 51-54 22678405-3 2012 METHODS: Following our published data from S-adenosylmethionine (SAMe), oxaliplatin and sorafenib were further used to stimulate GADD45beta expression in cultured HepG2 (p53 wild type) and Hep3B (p53 null) hepatoma cells in vitro. Sorafenib 88-97 P53 Homo sapiens 170-173 15460444-5 2004 These results suggest that activation of caspase-1 and -3 and the up-regulation of Bax are required in order for apoptotic death of SK-N-BE(2) cells to be induced by ginsenoside Rh2, and p53 plays an important role in the pathways to promote apoptosis. sk-n-be 132-139 P53 Homo sapiens 187-190 15225615-0 2004 A P53 target gene, PIG11, contributes to chemosensitivity of cells to arsenic trioxide. Arsenic Trioxide 70-86 P53 Homo sapiens 2-5 15308759-7 2004 Levels of p53 were quantified by sensitive fluorogenic enzyme-linked immunosorbent assay at intervals up to 24 h after exposure of cells to various concentrations of melphalan and monohydroxymelphalan. Melphalan 166-175 P53 Homo sapiens 10-13 15375563-2 2004 PAb421 binding restores wild-type functions of some p53 mutants, including those of SW480 human colon cancer cells. pab421 0-6 P53 Homo sapiens 52-55 15375563-6 2004 A single mutation in CDR1 of PAb421 VH eliminated binding of the Bs-scFv to p53 and abrogated cytotoxicity for SW480 cells without altering cellular penetration, further supporting the requirement of PAb421 binding to p53 for cytotoxicity. pab421 29-35 P53 Homo sapiens 76-79 15375563-6 2004 A single mutation in CDR1 of PAb421 VH eliminated binding of the Bs-scFv to p53 and abrogated cytotoxicity for SW480 cells without altering cellular penetration, further supporting the requirement of PAb421 binding to p53 for cytotoxicity. pab421 29-35 P53 Homo sapiens 218-221 15225615-3 2004 Recent data demonstrated that PIG11 was up-regulated markedly in arsenic trioxide induced apoptosis by DDRT-PCR, suggesting a new class of p53 target genes that sensitize cells to the effects of chemotherapeutic agents. Arsenic Trioxide 65-81 P53 Homo sapiens 139-142 22678405-3 2012 METHODS: Following our published data from S-adenosylmethionine (SAMe), oxaliplatin and sorafenib were further used to stimulate GADD45beta expression in cultured HepG2 (p53 wild type) and Hep3B (p53 null) hepatoma cells in vitro. Sorafenib 88-97 P53 Homo sapiens 196-199 15149862-3 2004 Loss of WRN or TP53 function resulted in induction of apoptosis and lesser proliferative survival in response to AraC and bleomycin. Bleomycin 122-131 P53 Homo sapiens 15-19 15284338-3 2004 In cell culturing, the deuterium-labeled (heavy) amino acids were incorporated into the proteome of the induced DLD-1.p53 cells, whereas the DLD-1.vector cells were grown in the unlabeled medium. Deuterium 23-32 P53 Homo sapiens 118-121 22096025-0 2012 Skin tumors induced by sorafenib; paradoxic RAS-RAF pathway activation and oncogenic mutations of HRAS, TP53, and TGFBR1. Sorafenib 23-32 P53 Homo sapiens 104-108 15802048-0 2004 Loss of p53 function in colon cancer cells results in increased phosphocholine and total choline.

Arsenic Trioxide 55-71 P53 Homo sapiens 256-259 15131059-1 2004 PURPOSE: On the basis of clinical studies showing that arsenic trioxide (As(2)O(3)), via an apoptotic mechanism, and with minimal toxicity induces complete remission in patients with refractory acute promyelocytic leukemia and that multidrug-resistant and p53-mutated neuroblastoma cells are sensitive to As(2)O(3) both in vitro and in vivo, we searched for molecular mechanisms involved in the As(2)O(3)-induced neuroblastoma cell death. Arsenic Trioxide 73-82 P53 Homo sapiens 256-259 15054096-9 2004 Pifithrin-alpha completely suppressed DOX-induced activation of p53 in both normal and tumor cell lines and prevented apoptosis in tumor cell lines but not in endothelial cells and cardiomyocytes. pifithrin 0-15 P53 Homo sapiens 64-67 15370294-6 2004 Fluvastatin did not regulate p21 and p27, but down-regulated Id3 and p53 slightly. Fluvastatin 0-11 P53 Homo sapiens 69-72 22945568-9 2012 Depending on the degree of DNA distortion and cell cycle progression, PAH-DNA adducts trigger nucleotide excision repair (NER) and various DNA damage responses that might include TP53-dependent apoptosis in certain cell types. Polycyclic Aromatic Hydrocarbons 70-73 P53 Homo sapiens 179-183 22945568-10 2012 In fact, cellular responses to bulky PAH-DNA damage are complex because distinct signaling branches such as ATM/ATR, NER, TP53, but also MAP kinases, interact and cooperate to determine the overall outcome to cellular injuries initiated by PAH-DNA adducts. Polycyclic Aromatic Hydrocarbons 37-40 P53 Homo sapiens 122-126 22945568-10 2012 In fact, cellular responses to bulky PAH-DNA damage are complex because distinct signaling branches such as ATM/ATR, NER, TP53, but also MAP kinases, interact and cooperate to determine the overall outcome to cellular injuries initiated by PAH-DNA adducts. Polycyclic Aromatic Hydrocarbons 240-243 P53 Homo sapiens 122-126 22862161-0 2012 Roscovitine-induced apoptosis of H1299 cells depends on functional status of p53. Roscovitine 0-11 P53 Homo sapiens 77-80 14715658-0 2004 S-(2-chloroethyl)glutathione-generated p53 mutation spectra are influenced by differential repair rates more than sites of initial dna damage. S-(2-chloroethyl)glutathione 0-28 P53 Homo sapiens 39-42 15007384-6 2004 The apoptosis induction due to As2O3 treatment of LNCaP cell correlated with the activation of JNK and p38 and induction of p53 protein. Arsenic Trioxide 31-36 P53 Homo sapiens 124-127 14715658-4 2004 The synthetic analog S-(2-chloroethyl)glutathione was used to produce DNA damage; the damage to the p53 exons was analyzed using a new fluorescence-based modification of ligation-mediated polymerase chain reaction and an automated sequencer. S-(2-chloroethyl)glutathione 21-49 P53 Homo sapiens 100-103 22862161-4 2012 In the presence of roscovitine, each cell line variant behaved in specific way reflecting activity of the p53 protein. Roscovitine 19-30 P53 Homo sapiens 106-109 22862161-7 2012 The cell expressing partially and conditionally active p53 mutants responded to roscovitine less efficiently. Roscovitine 80-91 P53 Homo sapiens 55-58 15285929-0 2004 Eicosapentaenoic acid induces Fas-mediated apoptosis through a p53-dependent pathway in hepatoma cells. ammonium ferrous sulfate 30-33 P53 Homo sapiens 63-66 22862161-8 2012 The cells expressing p53 mutants A159V and Y234C were very sensitive to roscovitine but their response was clearly temperature-dependent.

Bortezomib 62-72 P53 Homo sapiens 21-24 22862161-10 2012 In principle, each td p53 mutant responded to roscovitine in distinct way. Roscovitine 46-57 P53 Homo sapiens 22-25 14527925-1 2004 Functional regulation of p53 protein, a critical regulator of cell cycle and apoptosis, was investigated in fiberoptic bronchoscopy biopsy samples taken from 23 patients suffering from recurrent squamous cell lung cancer by analyzing the expression and phosphorylation status of the p53 at Ser15 and Ser20 before and after treatment with radiotherapy/cisplatin/vinorelbine. Vinorelbine 361-372 P53 Homo sapiens 25-28 22862161-11 2012 We showed clearly that the impact of roscovitine on H1299 cells depends on functional status of p53 they produce. Roscovitine 37-48 P53 Homo sapiens 96-99 15003520-3 2004 We investigated the ability of nitrotyrosine and nitrotyrosine-containing peptides (nitroY-peptide) to induce DNA damage by the experiments using 32P-labeled DNA fragments obtained from the human p53 tumor suppressor gene and an HPLC-electrochemical detector. 3-nitrotyrosine 31-44 P53 Homo sapiens 196-199 22862161-12 2012 This suggests that patients with tumors exhibiting specific p53 variants can benefit from the roscovitine therapy. Roscovitine 94-105 P53 Homo sapiens 60-63 14739660-6 2004 Our results demonstrated that high concentrations of MTBITC can also induce apoptosis, through an increase of p53 and bax, but not bcl-2, protein expression. 4-methylthiobutyl isothiocyanate 53-59 P53 Homo sapiens 110-113 22962590-0 2012 Ribavirin enhances the action of interferon-alpha against hepatitis C virus by promoting the p53 activity through the ERK1/2 pathway. Ribavirin 0-9 P53 Homo sapiens 93-96 14987952-6 2004 Besides, HepG2/C3A cells were found to be arrested in G(2)/M phase after the cells were treated with 60 microM emodin for 48 h. Moreover, significant increase in the levels of apoptosis-related signals such as p53 (419.3 pg/ml), p21 (437.4 units/ml), Fas (6.6 units/ml), and caspase-3 (35.4 pmol/min) were observed in emodin treated HepG2/C3A cells. ammonium ferrous sulfate 251-254 P53 Homo sapiens 210-213 15001399-6 2004 In contrast, in MCF-7 cells with wild type p53 and estrogen receptor, there was no change in Akt activation, while suppression of p53 activity by pifithrin-alpha increased phosphorylation of Akt after the treatment with copper. pifithrin 146-155 P53 Homo sapiens 130-133 14726646-3 2004 We have previously shown that ATO is a potent inducer of apoptosis in myeloma cells expressing mutant p53 engaging both the intrinsic and extrinsic apoptotic pathways. Arsenic Trioxide 30-33 P53 Homo sapiens 102-105 22962590-3 2012 We, therefore, decided to investigate whether and how ribavirin inhibits the replication of HCV by promoting the activity of p53.

Bortezomib 29-35 P53 Homo sapiens 194-197 22962590-7 2012 By knocking down ERK1/ERK2 and p53 utilizing RNA interference strategy, we further assessed the role of ERK1/2 and p53 in the suppression of HCV replication by ribavirin in a HCV replicon system. Ribavirin 160-169 P53 Homo sapiens 115-118 14975735-4 2004 Our data show that succinyl acetone-induced heme deficiency increases the protein levels of the tumor suppressor gene product p53 and CDK inhibitor p21, and decreases the protein levels of Cdk4, Cdc2, and cyclin D2. succinylacetone 19-35 P53 Homo sapiens 126-129 22962590-8 2012 RESULTS: Using HepG2 and HCV replicons, we demonstrated that ribavirin caused the cell cycle arrest at G1 phase and stabilized and activated p53, which was associated with the antiviral activity of ribavirin. Ribavirin 61-70 P53 Homo sapiens 141-144 22962590-8 2012 RESULTS: Using HepG2 and HCV replicons, we demonstrated that ribavirin caused the cell cycle arrest at G1 phase and stabilized and activated p53, which was associated with the antiviral activity of ribavirin. Ribavirin 198-207 P53 Homo sapiens 141-144 14712481-5 2004 These effects, associated with an up-regulation of p53, p21 and bax, a shuttling of p53 protein into the nucleus and a down-regulation of bcl-2, survivin and p27 protein, were reversed by the simultaneous addition of guanine or guanosine and were more evident using nondialysed serum containing hypoxanthine. Guanine 217-224 P53 Homo sapiens 51-54 14712481-5 2004 These effects, associated with an up-regulation of p53, p21 and bax, a shuttling of p53 protein into the nucleus and a down-regulation of bcl-2, survivin and p27 protein, were reversed by the simultaneous addition of guanine or guanosine and were more evident using nondialysed serum containing hypoxanthine.

Quercetin 46-55 P53 Homo sapiens 94-97 22905155-2 2012 This arrest can be abrogated in p53-defective cells by the Chk1 inhibitor 7-hydroxystaurosporine (UCN-01). 7-hydroxystaurosporine 98-104 P53 Homo sapiens 32-35 14767529-3 2004 The wild-type p53 HK1 was more susceptible to growth inhibition by quercetin than the mutant p53 CNE2. Quercetin 67-76 P53 Homo sapiens 14-17 15043303-15 2004 The 5-year PFS and DSS were significantly worse for carcinomas with a TP53 mutation (22.6% vs. 41.2% progressed [P = 0.04]; 21.7% vs. 24.7% died [P = 0.04]). dss 19-22 P53 Homo sapiens 70-74 22859938-9 2012 ER stress-induced p53 expression was significantly inhibited by coincubation with the NF-kappaB inhibitor, Bay 11-7082 and downregulation of NF-kappaB p65 expression. 3-(4-methylphenylsulfonyl)-2-propenenitrile 107-118 P53 Homo sapiens 18-21 22815878-6 2012 In contrast, administration of pifithrin-alpha (a p53 activity inhibitor) during hypoxia resulted in protein levels that were similar to those of the control groups. pifithrin 31-46 P53 Homo sapiens 50-53 14719107-0 2004 Induction of apoptosis by bleomycin in p53-null HL-60 leukemia cells. Bleomycin 26-35 P53 Homo sapiens 39-42 14719118-7 2004 Subsequently, flow cytometric analysis revealed a 2- to 4-fold increase in surface Fas/CD95 expression following Ad-p53 infection in mutant-p53-containing cell lines. ammonium ferrous sulfate 83-86 P53 Homo sapiens 116-119 14719118-7 2004 Subsequently, flow cytometric analysis revealed a 2- to 4-fold increase in surface Fas/CD95 expression following Ad-p53 infection in mutant-p53-containing cell lines. ammonium ferrous sulfate 83-86 P53 Homo sapiens 140-143 14623946-0 2004 Central role of mitochondria and p53 in Fas-mediated apoptosis of rheumatoid synovial fibroblasts. ammonium ferrous sulfate 40-43 P53 Homo sapiens 33-36 14719118-8 2004 Use of the protein transport inhibitor Brefeldin A significantly inhibited Ad-p53-induced surface Fas/CD95 expression, but only partially inhibited apoptosis in mutant-p53 cell lines. ammonium ferrous sulfate 98-101 P53 Homo sapiens 78-81 22359675-0 2012 Critical role of p53 upregulated modulator of apoptosis in benzyl isothiocyanate-induced apoptotic cell death. benzyl isothiocyanate 59-80 P53 Homo sapiens 17-20 14746616-8 2004 Two of 15 lesions examined presented p53 mutations located at nondipyrimidine sites. nondipyrimidine 62-77 P53 Homo sapiens 37-40 14998682-0 2004 Diepoxybutane induces caspase and p53-mediated apoptosis in human lymphoblasts. diepoxybutane 0-13 P53 Homo sapiens 34-37 22359675-4 2012 Instead, the BITC-treated MCF-7 and MDA-MB-231 cells exhibited upregulation of p53 upregulated modulator of apoptosis (PUMA) protein. benzyl isothiocyanate 13-17 P53 Homo sapiens 79-82 22072715-4 2011 A marked increase in the levels of p53 and p21 induced by Ang II was blunted by the treatment with GW501516. GW 501516 99-107 P53 Homo sapiens 35-38 14997055-10 2004 CONCLUSIONS: Breast-cancer-specific and all-cause mortality are increased in female breast cancer patients with the following p53 mutation characteristics: silent and missense mixed mutations, transitional mutations, mutations in which guanine changed, mutations on exon 7, or multiple mutations occurring within 60 codons. Guanine 236-243 P53 Homo sapiens 126-129 14657672-2 2004 Two distinct synthetic CDK1/2 inhibitors, Roscovitine and NU2058, are pharmacologically distinct in their ability to modify p53-dependent transcription and perturb cell cycle progression. Roscovitine 42-53 P53 Homo sapiens 124-127 14984262-12 2004 Moreover, DODC was found to induce the levels of p53 and an 18-kDa truncated Bax on mitochondria, which in turn potentiated the release of cytochrome c for activation of caspases. 3,3'-diethyloxadicarbocyanine 10-14 P53 Homo sapiens 49-52 14517211-0 2003 A defect in the p53 response pathway induced by de novo purine synthesis inhibition. purine 56-62 P53 Homo sapiens 16-19 14517211-2 2003 We now report that the p53-dependent G1 checkpoint is blocked in human carcinoma cell lines after inhibition of de novo purine synthesis by folate analogs inhibitory to glycinamide ribonucleotide formyltransferase (GART). purine 120-126 P53 Homo sapiens 23-26 22044530-5 2011 TCDD suppressed 1-NP- but not BaP-induced p53 activity, and in contrast, pifithrin-alpha (PFT-alpha), a p53 inhibitor, suppressed both 1-NP- and BaP-induced p53 activity. pifithrin 73-82 P53 Homo sapiens 104-107 17564316-0 2004 Elimination of methyl methanesulfonate (MMS)-induced micronuclei (MNS) under mild hyperthermia via p53-dependent pathway in human lymphoid cells. Methyl Methanesulfonate 15-38 P53 Homo sapiens 99-102 22044530-5 2011 TCDD suppressed 1-NP- but not BaP-induced p53 activity, and in contrast, pifithrin-alpha (PFT-alpha), a p53 inhibitor, suppressed both 1-NP- and BaP-induced p53 activity. pifithrin 73-82 P53 Homo sapiens 104-107 17564316-0 2004 Elimination of methyl methanesulfonate (MMS)-induced micronuclei (MNS) under mild hyperthermia via p53-dependent pathway in human lymphoid cells.

Methyl Methanesulfonate 38-41 P53 Homo sapiens 112-115 21685937-9 2011 Finally, we show that overexpression of SPARC renders cells more resistant to the p53-mediated cytotoxic effects of the DNA-damaging drug actinomycin-D. Deuterium 120-121 P53 Homo sapiens 82-85 15033759-8 2003 Moreover, sulforaphane induced apoptosis (and also necrosis), mediated by an increase in the expression of p53, whereas it exerted little effect on bcl-2 and bax levels. sulforaphane 10-22 P53 Homo sapiens 107-110 12888115-9 2003 However, dG-C8-AAF adducts produced greater p53 induction than dG-C8-AF adducts. N-(deoxyguanosin-8-yl)acetylaminofluorene 9-18 P53 Homo sapiens 44-47 21479885-0 2011 Quercetin enhances 5-fluorouracil-induced apoptosis in MSI colorectal cancer cells through p53 modulation.

Zidovudine 12-15 P53 Homo sapiens 109-112 22101337-7 2011 We also show that the checkpoint kinase inhibitor UCN-01 abolishes the G2 arrest induced by the veliparib and topotecan combination and further increases cell death in both p53-wildtype and -mutant cells. 7-hydroxystaurosporine 50-56 P53 Homo sapiens 173-176 12712406-10 2003 CONCLUSIONS: These results suggest that, in p53-mutated prostate cancer, JNK-initiated Fas-mediated apoptotic signals may play an important role in chemosensitivity. ammonium ferrous sulfate 87-90 P53 Homo sapiens 44-47 22101337-8 2011 Collectively, PARP inhibition by veliparib enhances DDR and cell death in BRCA-proficient cancer cells in a p53-dependent and -independent fashion. veliparib 33-42 P53 Homo sapiens 108-111 14687474-4 2003 RESULTS: The combination of PCNA-ASO and Ad-p53 inhibited cell viability in both the EJ (89.3%) and BIU-87 (78.6%) cell lines. biu 100-103 P53 Homo sapiens 44-47 21994207-0 2011 Enhancement of carboplatin- and quercetin-induced cell death by roscovitine is Akt dependent and p53 independent in hepatoma cells. Quercetin 32-41 P53 Homo sapiens 97-100 14688479-5 2003 In this study, we investigated the role of p53 and its downstream targets in bortezomib-induced apoptosis in HCT116 human colon cancer cells. Bortezomib 77-87 P53 Homo sapiens 43-46 14688479-6 2003 We demonstrated that bortezomib induced p53, and activated its downstream genes p21, PUMA and Bax in a p53-dependent fashion. Bortezomib 21-31 P53 Homo sapiens 40-43 12531793-0 2003 Arsenic trioxide-induced apoptosis in myeloma cells: p53-dependent G1 or G2/M cell cycle arrest, activation of caspase-8 or caspase-9, and synergy with APO2/TRAIL. Arsenic Trioxide 0-16 P53 Homo sapiens 53-56 12531793-4 2003 We tested the effect of ATO on 7 myeloma cell lines with varying p53 status and report that in cells with mutated p53, ATO induced rapid and extensive (more than 90%) apoptosis in a time- and dose-dependent manner concomitant with arrest of cells in G(2)/M phase of the cell cycle. Arsenic Trioxide 119-122 P53 Homo sapiens 65-68 12531793-4 2003 We tested the effect of ATO on 7 myeloma cell lines with varying p53 status and report that in cells with mutated p53, ATO induced rapid and extensive (more than 90%) apoptosis in a time- and dose-dependent manner concomitant with arrest of cells in G(2)/M phase of the cell cycle. Arsenic Trioxide 119-122 P53 Homo sapiens 114-117 12531793-5 2003 Myeloma cells with wild-type (wt) p53 were relatively resistant to ATO with maximal apoptosis of about 40% concomitant with partial arrest of cells in G(1) and up-regulation of p21. Arsenic Trioxide 67-70 P53 Homo sapiens 34-37 14688479-6 2003 We demonstrated that bortezomib induced p53, and activated its downstream genes p21, PUMA and Bax in a p53-dependent fashion. Bortezomib 21-31 P53 Homo sapiens 103-106 12531793-6 2003 The use of caspase blocking peptides, fluorescence-tagged caspase-specific substrate peptides, and Western immunoblotting confirmed the involvement of primarily caspase-8 and -3 in ATO-induced apoptosis in myeloma cells with mutated p53 and primarily caspase-9 and -3 in cells expressing wt p53. Arsenic Trioxide 181-184 P53 Homo sapiens 233-236 14688479-11 2003 These results indicate that p53 downstream targets can collectively modulate apoptotic response to bortezomib and other proteasome inhibitors. Bortezomib 99-109 P53 Homo sapiens 28-31 21438026-6 2011 MutHBx inhibited colony formation in p53-proficient cells (P < 0.01), but not p53-deficient lines. muthbx 0-6 P53 Homo sapiens 37-40 14682389-12 2003 The p53 protein was expressed in arsenic trioxide-treated cells, however, the densitometric analysis did not show any significant differences (p<0.05) between treated and control cells.

Arsenic Trioxide 181-184 P53 Homo sapiens 291-294 12734332-7 2003 Finally, in contrast to clonal deletion, PAH-induced pro/pre-B cell death was not dependent on p27(Kip1) or p21(WAF1) up-regulation but did coincide with p53 induction.

Vinorelbine 69-80 P53 Homo sapiens 109-112 14562033-5 2003 In contrast, p21 expression restored by vinorelbine in AI cells was found to be through both p53-dependent and-independent pathways.

Troglitazone 198-210 P53 Homo sapiens 149-152 12824901-8 2003 In the dominant-negative p53 mutant cells, troglitazone failed to induce apoptosis, strongly supporting the hypothesis that p53 indeed mediates the process of the troglitazone-induced apoptosis. Troglitazone 163-175 P53 Homo sapiens 124-127 12824901-9 2003 In the dominant-negative p53 mutant cells, troglitazone significantly induced cell growth arrest and increased expression of p27(Kip1) protein, which is thought to be the key molecule to evoke growth arrest, suggesting that p53 is not involved in the growth inhibition by troglitazone.

Methyl Methanesulfonate 63-66 P53 Homo sapiens 21-24 21110861-8 2010 The Meq variants L-Meq and S-Meq, but not VS-Meq and Meq, which were expressed in MD tumor cells and MDV-infected cells, exerted an inhibitory effect on p53 transcriptional activity. s-meq 27-32 P53 Homo sapiens 154-157 11375905-7 2001 Both lactacystin, a specific inhibitor of the 26S proteasome, and leptomycin B, a specific inhibitor of the nuclear export protein CRM1, could block the effect that DCA had on p53 protein levels, suggesting that DCA suppressed p53 by stimulating the process of proteasome-mediated degradation of p53. lactacystin 5-16 P53 Homo sapiens 176-179 11375905-7 2001 Both lactacystin, a specific inhibitor of the 26S proteasome, and leptomycin B, a specific inhibitor of the nuclear export protein CRM1, could block the effect that DCA had on p53 protein levels, suggesting that DCA suppressed p53 by stimulating the process of proteasome-mediated degradation of p53. lactacystin 5-16 P53 Homo sapiens 227-230 11375905-7 2001 Both lactacystin, a specific inhibitor of the 26S proteasome, and leptomycin B, a specific inhibitor of the nuclear export protein CRM1, could block the effect that DCA had on p53 protein levels, suggesting that DCA suppressed p53 by stimulating the process of proteasome-mediated degradation of p53. lactacystin 5-16 P53 Homo sapiens 227-230 11387205-2 2001 Here we provide evidence that overexpression of Gas2 efficiently increases cell susceptibility to apoptosis following UV irradiation, etoposide and methyl methanesulfonate treatments, and that these effects are dependent on increased p53 stability and transcription activity. Methyl Methanesulfonate 148-171 P53 Homo sapiens 234-237 11484935-2 2001 We found that four anticancer agents: etoposide, doxorubicin, bleomycin and paclitaxel induced apoptosis in human umbilical vein endothelial cells (HUVECs) (as judged by DNA fragmentation) with a time- and concentration-dependent decrease in bcl-2 protein but without the involvement of p53. Bleomycin 62-71 P53 Homo sapiens 287-290 12538456-7 2003 Quantitative reverse transcription-PCR analysis of the four p53 related genes [p21 (CDKN1A), FAS, BAK, and MDM2] revealed that Bak expression was increased significantly 24 h after Ad-p53 (INGN 201) injection and levels of CDKN1A and MDM2 expression were increased over the course of treatment. ammonium ferrous sulfate 93-96 P53 Homo sapiens 60-63 12488329-7 2003 Moreover, in prostate cancer cells, the synergism between 1,25-(OH)(2)D(3) and 9-cis retinoic acid appears to be dependent on the presence of functional p53; however, 1,25-(OH)(2)D(3)-mediated induction of G(1) cell cycle accumulation and induction of apoptosis is not. Isotretinoin 81-98 P53 Homo sapiens 153-156 12397013-0 2002 Hydrogen peroxide induces upregulation of Fas in human airway epithelial cells via the activation of PARP-p53 pathway. ammonium ferrous sulfate 42-45 P53 Homo sapiens 106-109 12397013-11 2002 These results indicate that H(2)O(2) induces Fas upregulation by promoting cytoplasmic transport of Fas to the cell surface in human airway epithelial cells, and that the activation of the poly(ADP-ribose) polymerase-p53 pathway may be involved in this mechanism. ammonium ferrous sulfate 45-48 P53 Homo sapiens 217-220 12530531-0 2002 Cyclin D3 and p53 mediate sulforaphane-induced cell cycle delay and apoptosis in non-transformed human T lymphocytes. sulforaphane 26-38 P53 Homo sapiens 14-17 12530531-2 2002 Following our previous demonstration that sulforaphane induces cell cycle arrest and apoptosis in human T lymphoblastoid Jurkat leukemia cells and increases p53 and bax protein expression, we tested sulforaphane on non-transformed phytohemagglutinin-stimulated human lymphocytes. sulforaphane 42-54 P53 Homo sapiens 157-160 11599886-0 2001 Fas-independent apoptosis induced by UVC in p53-mutated human epithelial tumor A431 cells through activation of caspase-8 and JNK/SAPK. ammonium ferrous sulfate 0-3 P53 Homo sapiens 44-47 12530531-4 2002 Moreover, sulforaphane induced apoptosis (and also necrosis), mediated by an increase in the expression of p53. sulforaphane 10-22 P53 Homo sapiens 107-110 21187919-8 2010 Furthermore, the combination of MNP-Fe3O4 with adriamycin or daunorubicin increased p53 protein levels and decreased NF-kappaB protein levels more than adriamycin or daunorubicin alone, indicating that MNP-Fe3O4 could enhance the effect of chemotherapeutic drugs on p53 and NF-kappaB. ferryl iron 36-41 P53 Homo sapiens 84-87 12379456-1 2002 The high frequency of G-->T transversions in the p53 gene is a distinctive feature of lung cancer patients with a smoking history and is commonly believed to reflect the direct mutagenic signature of polycyclic aromatic hydrocarbon (PAH) adducts along the gene.

Polycyclic Aromatic Hydrocarbons 64-67 P53 Homo sapiens 90-93 20932552-2 2010 We investigated the noncovalent binding interactions between 11 PAH metabolites and human p53 complementary DNA (p53 cDNA) using the fluorescence displacement method and molecular docking analysis. Polycyclic Aromatic Hydrocarbons 64-67 P53 Homo sapiens 113-116 20850841-3 2010 RESULTS: As expected, roscovitine caused dose and time dependent inhibition of cyclin dependent kinase 2 autophosphorylation, and of cyclin dependent kinase mediated Pol II phosphorylation in the ACHN (p53-wt) and 786-O (p53 inactive) renal cell carcinoma cell lines (ATCC ).

Roscovitine 22-33 P53 Homo sapiens 221-224 12171874-1 2002 Potentiation of 5-fluorouracil/leucovorin (FUra/LV) cytotoxicity by IFN-gamma in colon carcinoma cells is dependent on FUra-induced DNA damage, the Fas death receptor, and independent of p53 and RNA-mediated FUra toxicity, which occurs in normal gastrointestinal tissues. fura 119-123 P53 Homo sapiens 187-190 20850841-8 2010 Partial restoration of roscovitine induced apoptosis in 786-O cells by the Mdm-2 inhibitor nutlin-3 (Sigma-Aldrich) suggests that the inactivating mutation of VHL in these cells and its destabilizing effect on p53 are responsible for the decreased sensitivity to apoptosis. Roscovitine 23-34 P53 Homo sapiens 210-213 12131363-8 2002 The stilbene activated MAPK and caused increased abundance of p53 and serine-15 phosphorylated p53. Stilbenes 4-12 P53 Homo sapiens 62-65 20850841-9 2010 CONCLUSIONS: Our data extend previous studies documenting the pro-apoptotic effect of roscovitine and to our knowledge show for the first time that this activity is restricted to a narrow dose range in renal cell carcinoma cells and partly depends on p53. Roscovitine 86-97 P53 Homo sapiens 251-254 12131363-8 2002 The stilbene activated MAPK and caused increased abundance of p53 and serine-15 phosphorylated p53.

Glycerol 0-8 P53 Homo sapiens 100-103 12131363-13 2002 Pifithrin-alpha (Calbiochem), a p53 inhibitor, blocked resveratrol induced serine-15 phosphorylation of p53 and p53 binding to DNA. pifithrin 0-15 P53 Homo sapiens 104-107 12131363-13 2002 Pifithrin-alpha (Calbiochem), a p53 inhibitor, blocked resveratrol induced serine-15 phosphorylation of p53 and p53 binding to DNA. pifithrin 0-15 P53 Homo sapiens 104-107 12126446-3 2002 Both alkaloids displayed a cytotoxic profile against a panel of HCT-116 colon carcinoma cells indicative of a p53 dependent mechanism. Alkaloids 5-14 P53 Homo sapiens 110-113 11104574-3 2000 We examined the restoration of radiation-induced p53-dependent apoptosis by a chemical chaperone (glycerol) in human head and neck cancer cells (SAS cells, showing wild-type p53 phenotype). Glycerol 98-106 P53 Homo sapiens 49-52 11104574-3 2000 We examined the restoration of radiation-induced p53-dependent apoptosis by a chemical chaperone (glycerol) in human head and neck cancer cells (SAS cells, showing wild-type p53 phenotype). Glycerol 98-106 P53 Homo sapiens 174-177 20718603-2 2010 Pifithrin-alpha (PFT-alpha), a specific inhibitor of p53, has been suggested as a combinatory agent in the treatment of p53-deficient tumors in which inhibition of p53 would not compromise therapeutic efficacy but would decrease p53-mediated side effects in normal tissue. pifithrin 0-10 P53 Homo sapiens 120-123 11104574-4 2000 SAS cells transfected with mutant p53 (SAS/m p53) showed radioresistance compared with SAS cells (SAS/ neo) transfected with neo vector as a control, but became radiosensitive when pre-treated with glycerol before X-ray irradiation. Glycerol 198-206 P53 Homo sapiens 34-37 11104574-4 2000 SAS cells transfected with mutant p53 (SAS/m p53) showed radioresistance compared with SAS cells (SAS/ neo) transfected with neo vector as a control, but became radiosensitive when pre-treated with glycerol before X-ray irradiation. Glycerol 198-206 P53 Homo sapiens 45-48 11953432-6 2002 In the p53 mutant cells, low concentrations of UCN-01 caused S phase cells to progress to G(2) before undergoing mitosis and death, whereas high concentrations caused rapid premature mitosis and death of S phase cells. 7-hydroxystaurosporine 47-53 P53 Homo sapiens 7-10 20718603-2 2010 Pifithrin-alpha (PFT-alpha), a specific inhibitor of p53, has been suggested as a combinatory agent in the treatment of p53-deficient tumors in which inhibition of p53 would not compromise therapeutic efficacy but would decrease p53-mediated side effects in normal tissue. pifithrin 0-10 P53 Homo sapiens 120-123 11104574-5 2000 Apoptosis in the SAS/m p53 cells was induced by X-rays with glycerol pre-treatment, but not without glycerol pre-treatment, whereas apoptosis in the SAS/ neo cells was induced in both cases. Glycerol 60-68 P53 Homo sapiens 23-26 11104574-7 2000 These results suggest that glycerol is effective in inducing a conformational change of p53 and restoring normal function to mp53, leading to enhanced radiosensitivity through the induction of apoptosis. Glycerol 27-35 P53 Homo sapiens 88-91 21713362-6 2010 Activated p50/p65 and p53 forms were studied by ELISA and immunoblotting RESULTS: Pcy-triggered cell death was prevented by specific inhibitors of NF-kappaB and of p53: amino-4-(4-phenoxy-phenylethylamino) quinazoline (QNZ) and pifithrin alpha (Palpha), respectively. amino-4-(4-phenoxy-phenylethylamino) quinazoline 169-217 P53 Homo sapiens 164-167 11072242-0 2000 Induction of apoptosis in head-and-neck squamous carcinoma cells by gamma-irradiation and bleomycin is p53-independent. Bleomycin 90-99 P53 Homo sapiens 103-106 11102960-6 2000 Furthermore, 4H9 partially blocked the apoptosis induced by Ad5CMV-p53 in PC3 cells, but not in LNCaP and DU145 cells. (5-Amino-1h-1,2,4-Triazol-1-Yl)(4-Methoxyphenyl)methanone 13-16 P53 Homo sapiens 67-70 12063549-8 2002 As2O3 induced an increase in p53 level and a decrease in level of cyclin B1 combined with cell arrest at G2/M in both cell lines. Arsenic Trioxide 0-5 P53 Homo sapiens 29-32 12065694-7 2002 Treatment with the p53 inhibitor alpha-2-(2-imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone (PFT) before cisplatin exposure inhibited p53 nuclear expression at 4, 8, and 12 h and inhibited phosphatidylserine externalization and caspase 3 activation at 12 h. Neither DEVD-fmk nor ZVAD-fmk inhibited cisplatin-induced p53 nuclear expression. benzyloxycarbonylvalyl-alanyl-aspartyl fluoromethyl ketone 292-300 P53 Homo sapiens 19-22 12082016-10 2002 Flavonoids are known to have DNA topoisomerase activity, a Tp53-inducing activity that is confirmed in the assay. Flavonoids 0-10 P53 Homo sapiens 59-63 11844800-9 2002 Because inhibition of p53 is a common theme in human cancer, our data strongly support a role of DeltaTA-p73 expression for tumor formation. deltata 97-104 P53 Homo sapiens 22-25 11097865-3 2000 Our results revealed that ketoconazole-induced growth arrest was more profound in COLO 205 and Hep G2 (with wild-type p53) than in HT 29 (p53 His(273) mutant) and Hep 3B (with deleted p53) cells.

Ketoconazole 26-38 P53 Homo sapiens 138-141 11097865-3 2000 Our results revealed that ketoconazole-induced growth arrest was more profound in COLO 205 and Hep G2 (with wild-type p53) than in HT 29 (p53 His(273) mutant) and Hep 3B (with deleted p53) cells. Ketoconazole 26-38 P53 Homo sapiens 138-141 11097865-4 2000 The protein levels of p53, p21/Cip1, and p27/Kip1 were significantly elevated by ketoconazole (10 microM) treatment in COLO 205 but not in HT 29 cells. Ketoconazole 81-93 P53 Homo sapiens 22-25 11097865-5 2000 The ketoconazole-induced G0/G1 phase arrest in COLO 205 cells was attenuated by p53-specific antisense oligodeoxynucleotides (20 microM) treatment. Ketoconazole 4-16 P53 Homo sapiens 80-83 11097865-6 2000 These results suggested that the p53-associated signaling pathway is involved in the regulation of ketoconazole-induced cancer cell growth arrest. Ketoconazole 99-111 P53 Homo sapiens 33-36 11042698-8 2000 The activity of p53 on pro-apoptotic genes expression in response to DNA damage induced by (-irradiation, was affected in the vinblastine (VLB) resistant cell line but not in CCRF-CEM sensitive cell line resulting in a much reduced apoptotic cell death of the multi-drug resistant cells. Vinblastine 126-137 P53 Homo sapiens 16-19 11920959-4 2002 Assays using p53-null Saos2 cells were used to determine whether mammalian cells transfected with mutant p53 could up-regulate the MDR-1 or PCNA promoters, alter IL-6 expression or confer the ability to grow in soft agar. Agar 216-220 P53 Homo sapiens 105-108 11042698-8 2000 The activity of p53 on pro-apoptotic genes expression in response to DNA damage induced by (-irradiation, was affected in the vinblastine (VLB) resistant cell line but not in CCRF-CEM sensitive cell line resulting in a much reduced apoptotic cell death of the multi-drug resistant cells. Vinblastine 139-142 P53 Homo sapiens 16-19 20885891-5 2010 Because p53 plays a central role in the response to cellular stresses by upregulating the transcription of several genes controlling apoptosis, we aimed to study the involvement of p53 on lupulone-triggered apoptosis. lupulon 188-196 P53 Homo sapiens 8-11 10993652-4 2000 The p53(+)/RB(-)cells were susceptible to apoptosis under various experimental conditions: 1) incubation in serum-free culture for 72 h, 2) short-term (6 h) or long-term (48 h) exposure to etoposide, and 3) culturing in soft agar. Agar 225-229 P53 Homo sapiens 4-7 11839095-0 2002 Wild-type TP53 inhibits G(2)-phase checkpoint abrogation and radiosensitization induced by PD0166285, a WEE1 kinase inhibitor. PD 0166285 91-100 P53 Homo sapiens 10-14 11839095-3 2002 To determine the role of TP53 in PD0166285-induced G(2)-phase checkpoint abrogation, human H1299 lung carcinoma cells expressing a temperature-sensitive TP53 were used. PD 0166285 33-42 P53 Homo sapiens 25-29 11839095-5 2002 However, under permissive conditions (TP53 wild-type conformation), PD0166285 greatly inhibited the accumulation of cells in G(2) phase. PD 0166285 68-77 P53 Homo sapiens 38-42 11839095-9 2002 To understand the potential mechanism(s) by which TP53 inhibits PD0166285-induced G(2)-phase checkpoint abrogation, two TP53 target proteins, 14-3-3rho and CDKN1A (also known as p21), that are known to be involved in G(2)-phase checkpoint control in other cell models were examined. PD 0166285 64-73 P53 Homo sapiens 50-54 11839095-9 2002 To understand the potential mechanism(s) by which TP53 inhibits PD0166285-induced G(2)-phase checkpoint abrogation, two TP53 target proteins, 14-3-3rho and CDKN1A (also known as p21), that are known to be involved in G(2)-phase checkpoint control in other cell models were examined. PD 0166285 64-73 P53 Homo sapiens 120-124 11073163-5 2000 Induction of apoptosis by lactacystin or ZLLLal was accompanied by cell cycle arrest at G2/M phase and by accumulation and stabilization of cyclin-dependent kinase inhibitor p21WAF1/Cip and tumor suppressor protein p53. lactacystin 26-37 P53 Homo sapiens 215-218 11839095-12 2002 Thus inhibition of PD0166285-induced G(2)-phase checkpoint abrogation by TP53 was achieved at least in part through partial blockage of CDC2 dephosphorylation of Tyr15 and inhibition of cyclin B1 expression. PD 0166285 19-28 P53 Homo sapiens 73-77 20885891-5 2010 Because p53 plays a central role in the response to cellular stresses by upregulating the transcription of several genes controlling apoptosis, we aimed to study the involvement of p53 on lupulone-triggered apoptosis. lupulon 188-196 P53 Homo sapiens 181-184 11862326-0 2002 Proliferation-dependent induction of apoptosis by the retinoid CD437 in p53-mutated keratinocytes. Retinoids 54-62 P53 Homo sapiens 72-75 11006407-6 2000 Wortmannin significantly increased the BLM-induced aberration frequencies in all but the ATM-/- cells, elevating the sensitivity of p53-/- cells to ATM-/- levels and that of wild-type cells to intermediate levels. Bleomycin 39-42 P53 Homo sapiens 132-135 20885891-6 2010 Our data show that in SW620 cells, lupulone upregulated p53 gene expression and caused a cloistering of p53 in the nucleus, allowing p53 to play a proapoptotic role by activating the TRAIL-death receptor pathway. lupulon 35-43 P53 Homo sapiens 56-59 10942736-13 2000 NADPH, which accelerated the one-electron reduction of Cr(VI) to Cr(V) and increased.OH radical generation, dramatically enhanced p53 activation. NADP 0-5 P53 Homo sapiens 130-133 20885891-6 2010 Our data show that in SW620 cells, lupulone upregulated p53 gene expression and caused a cloistering of p53 in the nucleus, allowing p53 to play a proapoptotic role by activating the TRAIL-death receptor pathway. lupulon 35-43 P53 Homo sapiens 104-107 20885891-6 2010 Our data show that in SW620 cells, lupulone upregulated p53 gene expression and caused a cloistering of p53 in the nucleus, allowing p53 to play a proapoptotic role by activating the TRAIL-death receptor pathway. lupulon 35-43 P53 Homo sapiens 104-107 20885891-7 2010 In contrast, in lupulone-treated SW480 cells, p53 was translocated to the cytoplasm where it initiated a survival response associated with the up-regulation of antiapoptotic Bcl-2 and Mcl-1 proteins in an attempt to preserve mitochondrial integrity. lupulon 16-24 P53 Homo sapiens 46-49 11719452-0 2001 Radiosensitization of p53 mutant cells by PD0166285, a novel G(2) checkpoint abrogator. PD 0166285 42-51 P53 Homo sapiens 22-25 20885891-8 2010 These prosurvival effects of p53 in lupulone-treated SW480 cells were reversed by pifithrin-alpha, an inhibitor of p53 function, which caused a blocking of p53 in the nucleus leading to the down-regulation of Bcl-2 and Mcl-1, the up-regulation of proapoptotic Bax protein and TRAIL-death receptors leading to enhanced cell death. lupulon 36-44 P53 Homo sapiens 29-32 11585742-2 2001 Previous studies have indicated that there is an association between G-to-T transversion hotspots in lung cancers and sites of preferential formation of polycyclic aromatic hydrocarbon adducts along the p53 gene. Polycyclic Aromatic Hydrocarbons 153-184 P53 Homo sapiens 203-206 11068855-1 2000 The objective of the present work was to study the effects of 3"-azido-3"-deoxythymidine (azidothymidine, Zidovudine) on human breast cancer cells by using, as a model, the T47D cell line (typified as oestrogen-dependent and p53-mutated).

Zidovudine 106-116 P53 Homo sapiens 225-228 11585742-3 2001 p53 codons containing methylated CpG sequences are preferential targets for formation of adducts by (+/-) anti-7beta,8alpha-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE). 8alpha-dihydroxy-9alpha 117-140 P53 Homo sapiens 0-3 20885891-8 2010 These prosurvival effects of p53 in lupulone-treated SW480 cells were reversed by pifithrin-alpha, an inhibitor of p53 function, which caused a blocking of p53 in the nucleus leading to the down-regulation of Bcl-2 and Mcl-1, the up-regulation of proapoptotic Bax protein and TRAIL-death receptors leading to enhanced cell death. lupulon 36-44 P53 Homo sapiens 115-118 10933801-4 2000 Phosphoamino acid analysis and manual Edman degradation of the isolated phosphopeptides enabled us to unequivocally identify Thr-55 as the major phosphorylation site on p53. Phosphoamino Acids 0-17 P53 Homo sapiens 169-172 20885891-8 2010 These prosurvival effects of p53 in lupulone-treated SW480 cells were reversed by pifithrin-alpha, an inhibitor of p53 function, which caused a blocking of p53 in the nucleus leading to the down-regulation of Bcl-2 and Mcl-1, the up-regulation of proapoptotic Bax protein and TRAIL-death receptors leading to enhanced cell death. lupulon 36-44 P53 Homo sapiens 115-118 11562441-0 2001 The cyclin-dependent kinase inhibitor roscovitine inhibits RNA synthesis and triggers nuclear accumulation of p53 that is unmodified at Ser15 and Lys382. Roscovitine 38-49 P53 Homo sapiens 110-113 10945628-4 2000 Because poly(ADP-ribose) polymerase (PARP)-mediated NAD+/ATP depletion has been implicated in the nucleoside-induced killing of normal resting lymphocytes, we postulated that this mechanism might account for the p53-independent component of nucleoside cytotoxicity in CLL. Nucleosides 98-108 P53 Homo sapiens 212-215 11562441-1 2001 Roscovitine has been shown to induce the accumulation of the tumor suppressor p53, to arrest cells in the G(1) and G(2)/M phases of the cell cycle, and to induce apoptosis in human cells. Roscovitine 0-11 P53 Homo sapiens 78-81 20885891-9 2010 Our data support different functions of the same mutated p53 in colon adenocarcinoma and derived metastatic cells in response to the chemopreventive agent lupulone. lupulon 155-163 P53 Homo sapiens 57-60 11562441-7 2001 Cells treated with roscovitine at doses that affected transcription were found to accumulate p53 in the nucleus; curiously, however, the nuclear accumulation of p53 was not accompanied by modifications at either the Ser15 or Lys382 sites of p53. Roscovitine 19-30 P53 Homo sapiens 93-96 11562441-7 2001 Cells treated with roscovitine at doses that affected transcription were found to accumulate p53 in the nucleus; curiously, however, the nuclear accumulation of p53 was not accompanied by modifications at either the Ser15 or Lys382 sites of p53.

Roscovitine 19-30 P53 Homo sapiens 161-164 11562441-8 2001 We conclude that roscovitine is a potent inhibitor of RNA synthesis and that this inhibition may be responsible for the accumulation of nuclear p53. Roscovitine 17-28 P53 Homo sapiens 144-147 10945628-4 2000 Because poly(ADP-ribose) polymerase (PARP)-mediated NAD+/ATP depletion has been implicated in the nucleoside-induced killing of normal resting lymphocytes, we postulated that this mechanism might account for the p53-independent component of nucleoside cytotoxicity in CLL. Nucleosides 241-251 P53 Homo sapiens 212-215 10945628-10 2000 This indicates that PARP activity can occasionally be central to nucleoside-induced killing and that such PARP-mediated killing is p53 independent.

Phenylephrine 83-96 P53 Homo sapiens 175-178 11389075-8 2001 We found that vinblastine treatment caused down-regulation of p53 and its target p21 and up-regulation of tumor necrosis factor alpha, Bak, and several other genes in control but not in KB3-TAM67 cells, identifying these genes as putative targets of vinblastine-inducible AP-1. Vinblastine 14-25 P53 Homo sapiens 62-65 11465510-3 2001 In order to determine if the genotype of the p53 donor or the genotype of the sp donor determined the binding efficiency, p53 expression was induced by retinoic acid and sp synthesis by bleomycin.

Roscovitine 122-133 P53 Homo sapiens 162-165 20456495-7 2010 Curcuminoids also promote the phosphorylation of p53 on serine 15 in a dose-dependent and p38-dependent manner, suggesting that these compounds may activate p53. curcuminoids 0-12 P53 Homo sapiens 49-52 10543945-2 1999 Since CpGs are methylated along the p53 gene, these mutations may be derived from solar UV-induced pyrimidine dimers forming at sequences that contain 5-methylcytosine. 5-Methylcytosine 151-167 P53 Homo sapiens 36-39 10543945-9 1999 The data indicate that dipyrimidines that contain 5-methylcytosine are preferential targets for sunlight-induced mutagenesis in cultured mammalian cells, thus explaining the large proportion of p53 mutations at such sites in skin tumors in vivo. 5-Methylcytosine 50-66 P53 Homo sapiens 194-197 11165136-5 2001 ET-743 induced a significant increase in p53 levels in cell lines expressing wild-type (wt) (p53). Trabectedin 0-6 P53 Homo sapiens 41-44 11165136-5 2001 ET-743 induced a significant increase in p53 levels in cell lines expressing wild-type (wt) (p53). Trabectedin 0-6 P53 Homo sapiens 93-96 11146157-7 2000 The effect of Ad-p53 on colony-forming unit granulocyte-macrophage (CFU-GM) and burst-forming unit erythroid (BFU-E) colony formation in methylcellulose was tested on purified CD34(+) and CD34(-) cells to evaluate bone marrow toxicity. Methylcellulose 137-152 P53 Homo sapiens 17-20 20456495-7 2010 Curcuminoids also promote the phosphorylation of p53 on serine 15 in a dose-dependent and p38-dependent manner, suggesting that these compounds may activate p53. curcuminoids 0-12 P53 Homo sapiens 157-160 10488156-5 1999 For this purpose, we applied a recently developed random mutagenesis technique called DNA shuffling and screened for p53 variants that could retain reactivity to the native conformation-specific anti-p53 antibody PAb1620 upon thermal treatment. pab1620 213-220 P53 Homo sapiens 117-120 10488156-5 1999 For this purpose, we applied a recently developed random mutagenesis technique called DNA shuffling and screened for p53 variants that could retain reactivity to the native conformation-specific anti-p53 antibody PAb1620 upon thermal treatment. pab1620 213-220 P53 Homo sapiens 200-203 11096420-0 2000 Abrogation of G(2)/M-phase block enhances the cytotoxicity of daunorubicin, melphalan and cisplatin in TP53 mutant human tumor cells. Melphalan 76-85 P53 Homo sapiens 103-107 11096420-3 2000 In the TP53-mutated cell lines MeWo and 4451, the survival ratio at 7 Gy measured by colony formation was 2.3-2.8, 8.6-85 and 52-74 for daunorubicin, melphalan and cisplatin, respectively. Melphalan 150-159 P53 Homo sapiens 7-11 20456495-11 2010 Curcuminoids also synergize with UVB to enhance p53 phosphorylation. curcuminoids 0-12 P53 Homo sapiens 48-51 11103825-6 2000 CD437 induced Fas expression in three NSCLC cell lines with wild-type p53 but not in six NSCLC cell lines containing mutant p53. ammonium ferrous sulfate 14-17 P53 Homo sapiens 70-73 10520012-0 1999 The effect of p53 dysfunction on purine analogue cytotoxicity in chronic lymphocytic leukaemia. purine 33-39 P53 Homo sapiens 14-17 10520012-1 1999 To clarify the role of p53 in the killing of chronic lymphocytic leukaemia (CLL) cells by purine analogues, we examined the cytotoxic effects of chlorodeoxyadenosine and fludarabine on CLL cells that had been characterized according to their p53 functional status. purine 90-96 P53 Homo sapiens 23-26 20456495-12 2010 The findings provide a rationale for testing curcuminoids in disorders associated with impaired p53 function or in which UVB-treatment is efficacious. curcuminoids 45-57 P53 Homo sapiens 96-99 10520012-2 1999 Cases of CLL with p53 dysfunction (n = 7) displayed slight, but significant, resistance to nucleoside-induced cell killing when compared with cases with functionally intact p53 (n = 12). Nucleosides 91-101 P53 Homo sapiens 18-21 20515947-1 2010 Previously, we reported that the nucleoside analogue/transcriptional inhibitor ARC (4-amino-6-hydrazino-7-beta-D-ribofuranosyl-7H-pyrrolo(2,3-d)-pyrimidine-5-carboxamide) was able to induce p53-independent apoptosis in multiple cancer cell lines of different origins. Nucleosides 33-43 P53 Homo sapiens 190-193 10520012-4 1999 These findings suggest that the poor therapeutic response to purine analogues observed in patients with p53 defects is likely to be caused by the emergence, on a background of genomic instability, of CLL-cell clones that are resistant to nucleoside-induced killing for reasons unrelated to p53. purine 61-67 P53 Homo sapiens 104-107 10520012-4 1999 These findings suggest that the poor therapeutic response to purine analogues observed in patients with p53 defects is likely to be caused by the emergence, on a background of genomic instability, of CLL-cell clones that are resistant to nucleoside-induced killing for reasons unrelated to p53. purine 61-67 P53 Homo sapiens 290-293 10520012-4 1999 These findings suggest that the poor therapeutic response to purine analogues observed in patients with p53 defects is likely to be caused by the emergence, on a background of genomic instability, of CLL-cell clones that are resistant to nucleoside-induced killing for reasons unrelated to p53. Nucleosides 238-248 P53 Homo sapiens 104-107 10487521-0 1999 Induction of apoptosis by the p53-273L (Arg --> Leu) mutant in HSC3 cells without transactivation of p21Waf1/Cip1/Sdi1 and bax. Leucine 51-54 P53 Homo sapiens 30-33 10446979-9 1999 UV irradiation, bleomycin, and doxorubicin increased wild-type p53 expression and decreased MAP4 expression. Bleomycin 16-25 P53 Homo sapiens 63-66 11050000-5 2000 Expression of wt p53 also leads to cell cycle arrest and protection from doxorubicin (Dox)- and melphalan (Mel)-induced apoptosis. Melphalan 96-105 P53 Homo sapiens 17-20 11050000-5 2000 Expression of wt p53 also leads to cell cycle arrest and protection from doxorubicin (Dox)- and melphalan (Mel)-induced apoptosis. Melphalan 107-110 P53 Homo sapiens 17-20 11106264-11 2000 Therefore, in colon carcinomas that express wtp53, the approach to sensitize tumors to Fas-mediated apoptosis may be further enhanced from the effect of FUra-LV in elevating Fas expression in a p53-dependent manner. ammonium ferrous sulfate 87-90 P53 Homo sapiens 46-49 11106264-11 2000 Therefore, in colon carcinomas that express wtp53, the approach to sensitize tumors to Fas-mediated apoptosis may be further enhanced from the effect of FUra-LV in elevating Fas expression in a p53-dependent manner. ammonium ferrous sulfate 174-177 P53 Homo sapiens 46-49 11029511-1 2000 Previous research has shown synergistic growth inhibition between UCN-01 and camptothecin (CPT) in tumor cells with mutant p53 versus tumor cells with wild-type p53. 7-hydroxystaurosporine 66-72 P53 Homo sapiens 123-126 10435597-6 1999 In the current study, we demonstrate that TRID gene expression is also induced by the genotoxic agents ionizing radiation and methyl methanesulfonate (MMS) in predominantly p53 wild-type cells, whereas UV-irradiation does not induce TRID gene expression. Methyl Methanesulfonate 126-149 P53 Homo sapiens 173-176 20067769-10 2010 Finally, based on our studies we propose that NU1025 and possibly other inhibitors of PARP-1 may be used as non-genotoxic agents to activate p53 in tumor cells with non-functional p53 pathways. NU 1025 46-52 P53 Homo sapiens 141-144 10435597-6 1999 In the current study, we demonstrate that TRID gene expression is also induced by the genotoxic agents ionizing radiation and methyl methanesulfonate (MMS) in predominantly p53 wild-type cells, whereas UV-irradiation does not induce TRID gene expression. Methyl Methanesulfonate 151-154 P53 Homo sapiens 173-176 10944184-2 2000 A series of hydrophilic mutations at Met-340 and Leu-344 of human p53 were designed to disrupt the hydrophobic dimer-dimer interface of the tetrameric oligomerization domain of p53 (residues 325-355). Leucine 49-52 P53 Homo sapiens 66-69 10944184-2 2000 A series of hydrophilic mutations at Met-340 and Leu-344 of human p53 were designed to disrupt the hydrophobic dimer-dimer interface of the tetrameric oligomerization domain of p53 (residues 325-355). Leucine 49-52 P53 Homo sapiens 177-180 20067769-10 2010 Finally, based on our studies we propose that NU1025 and possibly other inhibitors of PARP-1 may be used as non-genotoxic agents to activate p53 in tumor cells with non-functional p53 pathways. NU 1025 46-52 P53 Homo sapiens 180-183 20463368-7 2010 DCA therapy also inhibited the hypoxia-inducible factor-1alpha, promoted p53 activation, and suppressed angiogenesis both in vivo and in vitro. Dichloroacetic Acid 0-3 P53 Homo sapiens 73-76 10891529-0 2000 Theophylline and cisplatin synergize in down regulation of BCL-2 induction of apoptosis in human granulosa cells transformed by a mutated p53 (p53 val135) and Ha-ras oncogene. Theophylline 0-12 P53 Homo sapiens 138-141 10891529-0 2000 Theophylline and cisplatin synergize in down regulation of BCL-2 induction of apoptosis in human granulosa cells transformed by a mutated p53 (p53 val135) and Ha-ras oncogene. Theophylline 0-12 P53 Homo sapiens 143-146 10891529-2 2000 We have examined the effect of cisplatin alone and in combination with theophylline, a phoshodiesterase inhibitor, on modulation of Bcl-2/Bax expression and induction of apoptosis in human granulosa cells transformed by stable transfection with mutant p53 plus Ha-ras. Theophylline 71-83 P53 Homo sapiens 252-255 10405003-1 1999 PURPOSE: To investigate the ability of docetaxel (Taxotere) to radiosensitize human cell lines of differing malignant status, intrinsic radiosensitivity and p53 status. Docetaxel 39-48 P53 Homo sapiens 157-160 10405003-1 1999 PURPOSE: To investigate the ability of docetaxel (Taxotere) to radiosensitize human cell lines of differing malignant status, intrinsic radiosensitivity and p53 status. Docetaxel 50-58 P53 Homo sapiens 157-160 10405003-4 1999 RESULTS: The experiments indicate that docetaxel had the greatest cytotoxic and radiosensitizing effect on the SW48 (p53wt) cell line. Docetaxel 39-48 P53 Homo sapiens 117-120 10449043-5 1999 In order to determine whether these conformational changes are consistent for other p53 mutants, we have now used molecular dynamics to determine the structure of the DNA-binding core domain of the Leu 179 p53 mutant. Leucine 198-201 P53 Homo sapiens 84-87 10449043-5 1999 In order to determine whether these conformational changes are consistent for other p53 mutants, we have now used molecular dynamics to determine the structure of the DNA-binding core domain of the Leu 179 p53 mutant. Leucine 198-201 P53 Homo sapiens 206-209 10449043-6 1999 The results indicate that the Leu 179 mutant differs substantially from the wild-type structure in certain discrete regions that are similar to those noted previously in the other p53 mutants. Leucine 30-33 P53 Homo sapiens 180-183 10082548-5 1999 Treatment with lactacystin (an inhibitor of the proteasome) or heat shock leads to similar levels of p53 accumulation in normal and AT fibroblasts, but the p53 protein lacks a phosphorylated serine 15. lactacystin 15-26 P53 Homo sapiens 101-104 10951228-4 2000 Recent evidence has shown that Fas-induced keratinocyte apoptosis in response to ultraviolet light, prevents the accumulation of pro-carcinogenic p53 mutations by deleting ultraviolet-mutated keratinocytes. ammonium ferrous sulfate 31-34 P53 Homo sapiens 146-149 10082548-5 1999 Treatment with lactacystin (an inhibitor of the proteasome) or heat shock leads to similar levels of p53 accumulation in normal and AT fibroblasts, but the p53 protein lacks a phosphorylated serine 15. lactacystin 15-26 P53 Homo sapiens 156-159 20372849-2 2010 Human head and neck squamous cell carcinoma (HNSCC) cells with different p53 status, and HSC4 (p53 wild-type) and CAL27 (p53 mutant type) cells were treated with docetaxel and irradiation using three schedules: i) concurrent treatment, ii) docetaxel pretreatment and iii) pre-radiation. Docetaxel 162-171 P53 Homo sapiens 95-98 10082548-6 1999 Following microinjection of HaeIII into lactacystin-treated normal fibroblasts, lactacystin-induced p53 protein is phosphorylated at serine 15 and stabilized even in the presence of cycloheximide. lactacystin 40-51 P53 Homo sapiens 100-103 10082548-6 1999 Following microinjection of HaeIII into lactacystin-treated normal fibroblasts, lactacystin-induced p53 protein is phosphorylated at serine 15 and stabilized even in the presence of cycloheximide. lactacystin 80-91 P53 Homo sapiens 100-103 10327065-7 1999 In addition, an antagonistic anti-CD95 ligand antibody (4H9) that interfered with the CD95-receptor-ligand interaction partially reduced the apoptosis induced by the wild-type p53 gene transfer in H1299 cells, whereas apoptosis of DLD-1 and SW620 cells occurred in the presence of 4H9. (5-Amino-1h-1,2,4-Triazol-1-Yl)(4-Methoxyphenyl)methanone 56-59 P53 Homo sapiens 176-179 10931684-2 2000 We wished to determine if TP53 function affected the response of cells to fluoropyrimidines and radiation, a combination used for tens of thousands of patients each year. fluoropyrimidines 74-91 P53 Homo sapiens 26-30 10891461-7 2000 Nuclear wild-type p53 accumulated after lactacystin treatment used at the discriminating concentration in malignant, but not in normal, lymphocytes. lactacystin 40-51 P53 Homo sapiens 18-21 10891461-10 2000 This could result in modification of apoptosis control, since in CLL-lymphocytes a highly upregulated ubiquitin-proteasome system, which controls p53 stability among other apoptotic factors, was correlated with an increased propensity of these cells to apoptosis triggered by lactacystin. lactacystin 276-287 P53 Homo sapiens 146-149 10327065-7 1999 In addition, an antagonistic anti-CD95 ligand antibody (4H9) that interfered with the CD95-receptor-ligand interaction partially reduced the apoptosis induced by the wild-type p53 gene transfer in H1299 cells, whereas apoptosis of DLD-1 and SW620 cells occurred in the presence of 4H9. (5-Amino-1h-1,2,4-Triazol-1-Yl)(4-Methoxyphenyl)methanone 281-284 P53 Homo sapiens 176-179 20372849-2 2010 Human head and neck squamous cell carcinoma (HNSCC) cells with different p53 status, and HSC4 (p53 wild-type) and CAL27 (p53 mutant type) cells were treated with docetaxel and irradiation using three schedules: i) concurrent treatment, ii) docetaxel pretreatment and iii) pre-radiation. Docetaxel 162-171 P53 Homo sapiens 95-98 20175992-1 2010 Selective binding of the wild type tumor suppressor protein p53 to negatively and positively supercoiled (sc) DNA was studied using intercalative drugs chloroquine (CQ), ethidium bromide, acridine derivatives and doxorubicin as a modulators of the level of DNA supercoiling. Ethidium 170-186 P53 Homo sapiens 60-63 10408175-3 1999 Quercetin, an inhibitor of heat-shock response, dose dependently suppressed the p53 accumulation induced by X-rays at more than 100 microM. Quercetin 0-9 P53 Homo sapiens 80-83 10845931-10 2000 However, the MDM2 protein could be easily detected after treatment of cells with the specific proteasome inhibitor lactacystin, suggesting a normal regulation of the p53-MDM2 regulating loop. lactacystin 115-126 P53 Homo sapiens 166-169 10747892-2 2000 Gadd45, a p53-regulated stress protein, plays an important role in the cell cycle G(2)-M checkpoint following exposure to certain types of DNA-damaging agents such as UV radiation and methylmethane sulfonate. Methyl Methanesulfonate 184-207 P53 Homo sapiens 10-13 9920742-1 1999 The reactivity of guanines in an oligonucleotide containing mutational hot spots within the p53 gene (codons 248 and 249), 5"-CCG1G2AG3G4CCCA-3", toward dimethyl sulfate (DMS) and aflatoxin B1-8,9-epoxide (AFB1-8,9-epoxide) was investigated by a modified Maxam-Gilbert technique. Guanine 18-26 P53 Homo sapiens 92-95 19739077-10 2010 The effect of MKT-077 on complement-mediated lysis of HCT116 p53(+/+) and p53(-/-) cells was found to be independent on the presence of p53. MKT 077 14-21 P53 Homo sapiens 61-64 10527073-4 1999 Most of C6 cells infected in vitro with rVV-p53 expressing the tumor suppressor p53 protein showed apoptosis specific morphological changes in DAPI-stained nuclei and DNA fragmentation pattern on gel electrophoresis; infection with VV induced low level of cell apoptosis. DAPI 143-147 P53 Homo sapiens 44-47 10527073-4 1999 Most of C6 cells infected in vitro with rVV-p53 expressing the tumor suppressor p53 protein showed apoptosis specific morphological changes in DAPI-stained nuclei and DNA fragmentation pattern on gel electrophoresis; infection with VV induced low level of cell apoptosis. DAPI 143-147 P53 Homo sapiens 80-83 9823314-3 1998 Apoptosis was induced by exposing cells to 50 microM N-methyl-N"-nitro-N-nitrosoguanidine (MNNG) for increasing lengths of time and was confirmed by: (a) oligonucleosomal fragmentation of chromatin; (b) increase in p53 levels; and (c) degradation of PARP into the characteristic M(r) 85,000 (COOH-terminal catalytic domain) and M(r) 29,000 (DNA-binding domain) peptide fragments. Methylnitronitrosoguanidine 53-89 P53 Homo sapiens 215-218 10814675-5 2000 METHODS: Here we have mapped the distribution of adducts induced by diol epoxides of additional PAHs: chrysene (CDE), 5-methylchrysene (5-MCDE), 6-methylchrysene (6-MCDE), benzo[c]phenanthrene (B[c]PDE), and benzo[g]chrysene (B[g]CDE) within exons 5, 7, and 8 of the p53 gene in human bronchial epithelial cells. Polycyclic Aromatic Hydrocarbons 96-100 P53 Homo sapiens 267-270 10811471-5 2000 In contrast, Ad-p53 showed additive effects with the antitubulin agents (paclitaxel and docetaxel) in all four of the cell lines tested. Docetaxel 88-97 P53 Homo sapiens 16-19 10767618-9 2000 With the advent of new techniques of molecular biology, mutations were investigated in the ras and p53 genes of tumors induced by vinyl chloride and urethane. Urethane 149-157 P53 Homo sapiens 99-102 10767625-1 2000 About 23% of mutations in hereditary human diseases and 24% of mutations in p53 in human cancers are G to A transitions at sites of cytosine methylation suggesting that these sites are either foci for DNA damage, or foci for damage that is poorly repaired. Cytosine 132-140 P53 Homo sapiens 76-79 20393600-10 2010 FasL upregulation and caspase-8 activation were decreased by p53 inhibitor pifithrin-alpha and antioxidant polyethylene glycol catalase. pifithrin 75-90 P53 Homo sapiens 61-64 10788533-6 2000 Of the p53 functional mutations, a substitution of Gly at amino acid residue 245 to Asp (G245D) was identified in two patients in three subclones. Aspartic Acid 84-87 P53 Homo sapiens 7-10 9735403-0 1998 Protein synthesis and transcriptional inhibitors control N-methyl-N"-nitro-N-nitrosoguanidine-induced levels of APC mRNA in a p53-dependent manner. Methylnitronitrosoguanidine 57-93 P53 Homo sapiens 126-129 20179216-7 2010 Moreover, tumors with high expression of genes involved in cell adhesion/angiogenesis as well as of wild-type TP53 were more likely to be resistant to Sagopilone therapy. sagopilone 151-161 P53 Homo sapiens 110-114 11245004-1 1998 OBJECTIVE: To establish a tetracycline-regulated expression model and to determine and verify whether a specific point mutant type p53 minigene, containing an Arg-->Leu substitution at amino acid 172, possesses a suppressing effect on human lung cancer. Leucine 168-171 P53 Homo sapiens 131-134 9733515-3 1998 Immunoprecipitated ATM had intrinsic protein kinase activity and phosphorylated p53 on serine-15 in a manganese-dependent manner. Manganese 102-111 P53 Homo sapiens 80-83 9713990-6 1998 Under conditions of cellular stress (ultraviolet irradiation or exposure to bleomycin or cisplatin), expression of TP53TG1 was induced in a wild-type TP53-dependent manner, indicating that this gene is likely to play an important role in the signaling pathway of TP53 and may function in response to cellular damage. Bleomycin 76-85 P53 Homo sapiens 115-119 10774750-4 2000 The alkylation sites observed in exon 9 of the p53 gene revealed that the most high reactivity sites for altromycin B were found to be N7 of guanine in a 5"-AG* sequence. Guanine 141-148 P53 Homo sapiens 47-50 10751606-5 2000 AraC treatment significantly increased the frequency of bleomycin-induced chromatid aberrations in p53+/+ MEF to the levels in p53-/- (no AraC) but had no effect in p53-/- MEF. Bleomycin 56-65 P53 Homo sapiens 127-130 10751606-5 2000 AraC treatment significantly increased the frequency of bleomycin-induced chromatid aberrations in p53+/+ MEF to the levels in p53-/- (no AraC) but had no effect in p53-/- MEF. Bleomycin 56-65 P53 Homo sapiens 127-130 10751606-7 2000 Similar results were observed in p53-mutant WTK1 and wild-type TK6 human lymphoblast cells exposed to 0 to 3 microg/ml bleomycin in G(2). Bleomycin 119-128 P53 Homo sapiens 33-36 9713990-6 1998 Under conditions of cellular stress (ultraviolet irradiation or exposure to bleomycin or cisplatin), expression of TP53TG1 was induced in a wild-type TP53-dependent manner, indicating that this gene is likely to play an important role in the signaling pathway of TP53 and may function in response to cellular damage. Bleomycin 76-85 P53 Homo sapiens 150-154 9687575-10 1998 The results also suggest that p53 induction in response to O6-guanine methylation involves the mismatch repair system. Guanine 62-69 P53 Homo sapiens 30-33 19676051-6 2010 Under conditions where single-agent treatment caused only antiproliferative effects, the combination of the atypical retinoid and HDAC inhibitor resulted in marked apoptotic cell death with a more rapid onset in wild-type p53 ovarian carcinoma cells. Retinoids 117-125 P53 Homo sapiens 222-225 9726816-5 1998 In contrast, PDTC, DDTC, and ammonium dithiocarbamate (ADTC) did not induce apoptosis; rather they led to the induction of p53 and p21 followed by G1/S arrest. AMMONIUM DITHIOCARBAMATE 29-53 P53 Homo sapiens 123-126 9690517-9 1998 Thus, our results indicate that the p53-p21 pathway may play a central role in mediating the gene-regulatory and cytotoxic effects of aziridinylbenzoquinones. diaziquone 134-157 P53 Homo sapiens 36-39 9703875-0 1998 Increased p21/WAF-1 and p53 protein levels following sequential three drug combination regimen of fludarabine, cytarabine and docetaxel induces apoptosis in human leukemia cells. Docetaxel 126-135 P53 Homo sapiens 24-27 9622079-1 1998 17-(Allylamino)-17-demethoxygeldanamycin (17AAG), a compound that is proposed for clinical development, shares the ability of geldanamycin to bind to heat shock protein 90 and GRP94, thereby depleting cells of p185erbB2, mutant p53, and Raf-1. tanespimycin 0-40 P53 Homo sapiens 228-231 9622079-1 1998 17-(Allylamino)-17-demethoxygeldanamycin (17AAG), a compound that is proposed for clinical development, shares the ability of geldanamycin to bind to heat shock protein 90 and GRP94, thereby depleting cells of p185erbB2, mutant p53, and Raf-1. tanespimycin 42-47 P53 Homo sapiens 228-231 9584191-7 1998 By comparison, the DNA-damaging drugs methotrexate and doxorubicin had no effect on Bcl2 hyperphosphorylation but induced p53 expression. Methotrexate 38-50 P53 Homo sapiens 122-125 9619871-5 1998 p53, bax and bcl-xL were expressed at the same level in 4-pp-R and RVC cells. 4-pp 56-60 P53 Homo sapiens 0-3 9566927-3 1998 However, this conclusion derives from studies employing the UMP synthesis inhibitor N-phosphonacetyl-L-aspartate (PALA), which, in addition to selecting for cells containing extra copies of the CAD locus, enables p53-deficient cells to enter S phase and acquire the DNA breaks that initiate the amplification process. sparfosic acid 84-112 P53 Homo sapiens 213-216 9566927-5 1998 The studies reported here assess whether p53 deficiency leads to spontaneous genetic instability by comparing cell cycle responses and amplification frequencies of the human fibrosarcoma cell line HT1080 when treated with PALA or with methotrexate, an antifolate that, under the conditions used, should not generate DNA breaks. Methotrexate 235-247 P53 Homo sapiens 41-44 9591783-4 1998 Based on these results, we propose a mechanism by which PAb1620 can allosterically inhibit p53 binding to DNA through an indirect interaction between the antibody binding site and the L1 loop (amino acids 112-124) of p53, which is a component of the DNA binding region. pab1620 56-63 P53 Homo sapiens 91-94 9548807-0 1998 Induction of p53 by the concerted actions of aziridine and quinone moieties of diaziquone. diaziquone 79-89 P53 Homo sapiens 13-16 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. diaziquone 0-10 P53 Homo sapiens 131-134 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. diaziquone 12-15 P53 Homo sapiens 131-134 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. pycnogenols 80-83 P53 Homo sapiens 131-134 9502788-5 1998 Accordingly, bafilomycin A1-treated myocytes also showed increased accumulation of p53 protein and p53-dependent transactivation of gene expression, including a persistent upregulation of p21/wild-type p53 activated fragment 1/cyclin kinase inhibitor protein-1 mRNA. bafilomycin A1 13-27 P53 Homo sapiens 83-86 9502788-5 1998 Accordingly, bafilomycin A1-treated myocytes also showed increased accumulation of p53 protein and p53-dependent transactivation of gene expression, including a persistent upregulation of p21/wild-type p53 activated fragment 1/cyclin kinase inhibitor protein-1 mRNA. bafilomycin A1 13-27 P53 Homo sapiens 99-102 9502788-5 1998 Accordingly, bafilomycin A1-treated myocytes also showed increased accumulation of p53 protein and p53-dependent transactivation of gene expression, including a persistent upregulation of p21/wild-type p53 activated fragment 1/cyclin kinase inhibitor protein-1 mRNA. bafilomycin A1 13-27 P53 Homo sapiens 99-102 9502788-6 1998 The bafilomycin A1-induced increase in p53 protein levels was accompanied by a marked increase in p53 mRNA accumulation. bafilomycin 4-15 P53 Homo sapiens 39-42 9502788-6 1998 The bafilomycin A1-induced increase in p53 protein levels was accompanied by a marked increase in p53 mRNA accumulation. bafilomycin 4-15 P53 Homo sapiens 98-101 9497376-4 1998 In vitro studies have shown that E6AP can form a high energy thiolester bond with ubiquitin and, in the presence of E6, transfer ubiquitin to p53. Polyurethane Y-290 33-35 P53 Homo sapiens 142-145 9458377-5 1998 These findings suggest that Fas-mediated therapy could be a novel approach to RCC, if interferon- treatment is added according to the p53 gene status. ammonium ferrous sulfate 28-31 P53 Homo sapiens 134-137 9649296-0 1998 Methotrexate resistance in human uroepithelial cells with p53 alterations. Methotrexate 0-12 P53 Homo sapiens 58-61 9649296-3 1998 We tested if the status of p53 and/or pRb affects the development of MTX resistance in bladder epithelial cell lines. Methotrexate 69-72 P53 Homo sapiens 27-30 9649296-7 1998 RESULTS: Two cell lines with both pRb and p53 alterations, alphaE6/E7-HUC and alphaE7-HUCp53mu, acquired the greatest resistance (750 nM) to MTX. Methotrexate 141-144 P53 Homo sapiens 42-45 9649296-11 1998 In addition, two of five MTX resistant cell lines, both with altered p53, showed dihydrofolate reductase (DHFR) amplification. Methotrexate 25-28 P53 Homo sapiens 69-72 9649296-12 1998 CONCLUSIONS: p53 alteration increases the risk for development of drug resistance by both DHFR amplification and altered MTX transport in transformed human bladder epithelial cell lines. Methotrexate 121-124 P53 Homo sapiens 13-16 9463482-7 1998 The ellipticiniums, but not the ellipticines, were more potent on average against p53 mutant cells than against p53 wild-type ones (i.e., they seemed to be "p53-inverse") in this short term assay. ellipticiniums 4-18 P53 Homo sapiens 82-85 9463482-7 1998 The ellipticiniums, but not the ellipticines, were more potent on average against p53 mutant cells than against p53 wild-type ones (i.e., they seemed to be "p53-inverse") in this short term assay. ellipticiniums 4-18 P53 Homo sapiens 112-115 9463482-7 1998 The ellipticiniums, but not the ellipticines, were more potent on average against p53 mutant cells than against p53 wild-type ones (i.e., they seemed to be "p53-inverse") in this short term assay. ellipticiniums 4-18 P53 Homo sapiens 112-115 9438391-2 1998 Using the proteasome-specific inhibitors, MG132 (N-acetyl-L-leucinyl-L-leucinal-L-leucinal) and lactacystin, here we show that the p53-response proteins, bax and mdm2 as well as p21, are degraded by the ubiquitin-proteasome pathway in HeLa cells. lactacystin 96-107 P53 Homo sapiens 131-134 9516963-6 1998 Data demonstrated p53-dependent sensitization (> or = 4-fold) to bleomycin, actinomycin D, and 5-fluorouracil and considerably less p53-dependence (< or = 2-fold) for doxorubicin, topotecan, etoposide, and cisplatin in Cl.#27 compared to an equivalent clone containing the pGRE5-EBV vector alone (VC#3). Bleomycin 68-77 P53 Homo sapiens 18-21 9447384-0 1997 Apoptosis occurs more frequently in intraductal carcinoma than in infiltrating duct carcinoma of human breast cancer and correlates with altered p53 expression: detected by terminal-deoxynucleotidyl-transferase-mediated dUTP-FITC nick end labelling (TUNEL). dutp-fitc 220-229 P53 Homo sapiens 145-148 9307289-0 1997 Abrogation of an S-phase checkpoint and potentiation of camptothecin cytotoxicity by 7-hydroxystaurosporine (UCN-01) in human cancer cell lines, possibly influenced by p53 function. 7-hydroxystaurosporine 85-107 P53 Homo sapiens 168-171 9190897-5 1997 We found that this impairment of p53 turnover can be reversed by treatment of tumor cells with the benzoquinone ansamycin, geldanamycin, leading to a marked reduction in intracellular p53 levels. benzoquinone ansamycin 99-121 P53 Homo sapiens 33-36 9190897-5 1997 We found that this impairment of p53 turnover can be reversed by treatment of tumor cells with the benzoquinone ansamycin, geldanamycin, leading to a marked reduction in intracellular p53 levels. benzoquinone ansamycin 99-121 P53 Homo sapiens 184-187 9815762-0 1997 Accumulation of p53 protein and retinoic acid receptor beta in retinoid chemoprevention. Retinoids 63-71 P53 Homo sapiens 16-19 9815762-8 1997 High p53 protein expression (LI >/= 0.2) was detected in 25% of the lesions at baseline and in 18% of the lesions after isotretinoin therapy. Isotretinoin 123-135 P53 Homo sapiens 5-8 21533491-7 1997 Induction of apoptosis in JCA-1 cells by treatment with the retinoid 4-HPR caused the virtual disappearance of p53, which coincided with specific processing of p53 into lower molecular weight 28 kD fragments. Retinoids 60-68 P53 Homo sapiens 111-114 21533491-7 1997 Induction of apoptosis in JCA-1 cells by treatment with the retinoid 4-HPR caused the virtual disappearance of p53, which coincided with specific processing of p53 into lower molecular weight 28 kD fragments. Retinoids 60-68 P53 Homo sapiens 160-163 9154813-4 1997 Treatment of cytoplasmic extracts with RNase or puromycin in the presence of high salt, both of which are known to disrupt ribosomal function, dissociated p53 polypeptide from the ribosomes. Puromycin 48-57 P53 Homo sapiens 155-158 9136075-8 1997 Droloxifene, but not estrogen, induced p53 expression and apoptosis in MCF-7 cells. droloxifene 0-11 P53 Homo sapiens 39-42 9022073-10 1997 These data suggest that apoptosis induced by bleomycin is mediated, at least in part, by p53-dependent stimulation of the CD95 receptor/ligand system. Bleomycin 45-54 P53 Homo sapiens 89-92 15622746-5 1997 Furthermore, As2O3 effectively down-regulated the expression of bcl-2 gene without changing the mRNA levels of other apoptosis-associated genes (including p53, c-myc, bax and bcl-XL). Arsenic Trioxide 13-18 P53 Homo sapiens 155-158 8956076-5 1996 Phosphoamino acid was incorporated into the N-terminal segment (1P315) at the residue corresponding to p53 serine 315 as Boc-Ser(PO3(Bzl)2)-OH during synthesis. Phosphoamino Acids 0-17 P53 Homo sapiens 103-106 8895505-0 1996 Flavonoids activate wild-type p53. Flavonoids 0-10 P53 Homo sapiens 30-33 8895505-4 1996 To further elucidate this dual role, we investigated the influence of apigenin, luteolin and quercetin on the tumour suppressor protein p53, regarding p53 accumulation, cell cycle arrest, apoptosis, and biological activity. Quercetin 93-102 P53 Homo sapiens 136-139 8895505-5 1996 We found that incubation of the non-tumour cell line C3H10T1/2CL8 with these flavonoids resulted in induction of p53 accumulation and apoptosis. Flavonoids 77-87 P53 Homo sapiens 113-116 8895505-8 1996 Differences between the flavonoids tested concerned p53 accumulation kinetics as well as the biological activity of accumulated p53 and might be due to different modes of flavonoid action. Flavonoids 24-34 P53 Homo sapiens 52-55 8895505-8 1996 Differences between the flavonoids tested concerned p53 accumulation kinetics as well as the biological activity of accumulated p53 and might be due to different modes of flavonoid action. Flavonoids 24-33 P53 Homo sapiens 52-55 8895505-9 1996 These data suggest that both aspects of flavonoid effects, i.e. inhibition of tumour growth through cell cycle arrest and induction of apoptosis, are functionally related to p53. Flavonoids 40-49 P53 Homo sapiens 174-177 9031099-14 1996 Finally, whereas CLB and nucleoside analogs may produce cell death in CLL by a P53 dependent pathway other agents, such as dexamethasone or vincristine, may act through P53-independent pathways. Nucleosides 25-35 P53 Homo sapiens 79-82 8845023-9 1996 Indeed it was found that TEC-induced apoptosis, led to the accumulation of p53 protein that preceded the step of DNA fragmentation in freshly isolated thymocytes as well as in a glucocorticoid resistant thymoma cell line. Turpentine 25-28 P53 Homo sapiens 75-78 8822937-6 1996 For p53 we observed an overexpression in the presence of chlorambucil or both theophylline-chlorambucil and a decrease after theophylline incubation. Theophylline 78-90 P53 Homo sapiens 4-7 8896794-7 1996 The dehydrating (coagulant) fixatives (e.g., ethanol and methanol) preserved immunorecognition of p53 and broad spectrum keratins best while the slow cross-linking fixatives (e.g., unbuffered zinc formalin) were best for demonstrating TGF alpha and p185erbB-2. Methanol 57-65 P53 Homo sapiens 98-101 8787680-6 1996 To determine whether the lonidamine-induced apoptosis is mediated by p53 protein, we used cells lacking endogenous p53 and overexpressing either wild-type p53 or dominant-negative p53 mutant. lonidamine 25-35 P53 Homo sapiens 69-72 8706003-0 1996 Separate pathways for p53 induction by ionizing radiation and N-(phosphonoacetyl)-L-aspartate. sparfosic acid 62-93 P53 Homo sapiens 22-25 8706003-4 1996 Here, we demonstrate the existence of cell types in which the induction of p53 and associated G1 arrest by the antimetabolite, N-(phosphonoacetyl)-L-aspartate (PALA), is defective, whereas p53 induction and G1 arrest induced by ionizing radiation are intact. sparfosic acid 127-158 P53 Homo sapiens 75-78 8761369-1 1996 The aim of this investigation was to examine the possibility of analysing TP53 mutations in archival paraffin-embedded material with the constant denaturant gel electrophoresis (CDGE) method. cdge 178-182 P53 Homo sapiens 74-78 8757686-6 1996 Aberrant expression of p53 protein was documented in 48% of squamous cell carcinomas of skin, 29% of CRC, 22% of CIN and 23% of TCC. Triclocarban 128-131 P53 Homo sapiens 23-26 8783012-7 1996 We suggest that these variants contained a gamma-N, N"-dimethylasparagine residue at position 83 and that one of them was additionally oxidized at Trp53 and Trp85. gamma-n, n"-dimethylasparagine 43-73 P53 Homo sapiens 147-152 8790940-4 1996 Although the mutated p53 is selectively expressed in the immortalized cells, expression of the wild-type p53 was induced by treatment of the cells with a hypomethylating reagent, 5-azacytidine, indicating that the wild-type p53 allele might be inactivated by hypermethylation of DNA. Azacitidine 179-192 P53 Homo sapiens 105-108 8790940-4 1996 Although the mutated p53 is selectively expressed in the immortalized cells, expression of the wild-type p53 was induced by treatment of the cells with a hypomethylating reagent, 5-azacytidine, indicating that the wild-type p53 allele might be inactivated by hypermethylation of DNA. Azacitidine 179-192 P53 Homo sapiens 105-108 7478511-0 1995 Induction of Fas-mediated apoptosis in p53-transfected human colon carcinoma cells. ammonium ferrous sulfate 13-16 P53 Homo sapiens 39-42 7478511-4 1995 The efficiency of colony formation in soft agar, however, was completely suppressed in two wild-type p53+ clones. Agar 43-47 P53 Homo sapiens 101-104 7478511-7 1995 The findings suggest that a Fas-initiated pathway is incidentally linked to a p53-dependent apoptotic pathway through the reconstituted wild-type p53 gene in WiDr cells. ammonium ferrous sulfate 28-31 P53 Homo sapiens 78-81 7478511-7 1995 The findings suggest that a Fas-initiated pathway is incidentally linked to a p53-dependent apoptotic pathway through the reconstituted wild-type p53 gene in WiDr cells. ammonium ferrous sulfate 28-31 P53 Homo sapiens 146-149 7478567-4 1995 In contrast, the increase in p53 protein, WAF1/CIP1(p21) and GADD45 mRNA expression following exposure to the alkylating agent methylmethane sulphonate (25 and 100 micrograms ml-1) was similar in both cell types. Methyl Methanesulfonate 127-151 P53 Homo sapiens 29-32 7586148-4 1995 Two cell lines selected from V79/B7 for their resistance to phosphonacetyl-L-aspartate or methotrexate and previously shown to bear gene amplification, showed p53 expression. Methotrexate 90-102 P53 Homo sapiens 159-162 7605998-0 1995 Amplification of the dihydrofolate reductase gene is a mechanism of acquired resistance to methotrexate in patients with acute lymphoblastic leukemia and is correlated with p53 gene mutations. Methotrexate 91-103 P53 Homo sapiens 173-176 7538902-3 1995 Following DNA strand break damage induced by bleomycin, both SDI1 induction and G1-S cell cycle arrest are p53 dependent, consistent with SDI1 being the key mediator. Bleomycin 45-54 P53 Homo sapiens 107-110 7751883-0 1995 Prognostic value of p53 nuclear overexpression in patients with invasive bladder cancer treated with neoadjuvant MVAC. mvac 113-117 P53 Homo sapiens 20-23 7622024-2 1995 It was shown that injection of a retroviral construction with p53His273 resulted in the accumulation of methotrexate-resistant variants with an increased number of dhfr copies in populations of recipient cells. Methotrexate 104-116 P53 Homo sapiens 62-65 7783370-3 1995 The results of several fixation methods demonstrated that formalin and methanol, formalin and ethanol (1:9) and buffered formalin acetone gave good results for detecting p53 protein. Methanol 71-79 P53 Homo sapiens 170-173 7897229-6 1995 First, the amount of immunoreactive p53-56lyn increased in Triton X-100-insoluble fraction as did zymosan-stimulated tyrosine phosphoproteins. Octoxynol 59-71 P53 Homo sapiens 36-39 7897229-10 1995 Third, p53-56lyn was probably activated after cell stimulation with zymosan, because the phosphorylation levels of a synthetic copolymer of glutamine-tyrosine were increased in Triton X-100-insoluble fraction. Octoxynol 177-189 P53 Homo sapiens 7-10 7567152-2 1995 Two 20-base oligomers complementary to bases 872-891 of human p53 cDNA with a single nucleotide difference in the third position of codon 249 were end-labelled with biotin-conjugated dATP using terminal deoxynucleotidyltransferase (TdT). 2'-deoxyadenosine triphosphate 183-187 P53 Homo sapiens 62-65 7888675-0 1995 p53 gene deletion predicts for poor survival and non-response to therapy with purine analogs in chronic B-cell leukemias. purine 78-84 P53 Homo sapiens 0-3 7888675-12 1995 In conclusion, p53 gene deletion predicts for non-response to therapy with purine analogs and for poor survival in chronic B-cell leukemias. purine 75-81 P53 Homo sapiens 15-18 7534296-5 1995 These effects are reversed by subsequent dephosphorylation of the protein kinase C-reactive site by protein phosphatases 1 (PP1) and 2A (PP2A), which restore the reactivity of p53 to PAb421 and regenerate the latent form of p53 lacking significant DNA binding activity. pab421 183-189 P53 Homo sapiens 176-179 7534296-5 1995 These effects are reversed by subsequent dephosphorylation of the protein kinase C-reactive site by protein phosphatases 1 (PP1) and 2A (PP2A), which restore the reactivity of p53 to PAb421 and regenerate the latent form of p53 lacking significant DNA binding activity. pab421 183-189 P53 Homo sapiens 224-227 7854771-6 1995 The expression of p53 was reduced to 60% for the first 4 h after the addition of cycloheximide, and showed no significant changes at least for 20 h. Treatment with Triton X-100 increased p53 immunoreactivity throughout the cell cycle. Octoxynol 164-176 P53 Homo sapiens 18-21 7854771-6 1995 The expression of p53 was reduced to 60% for the first 4 h after the addition of cycloheximide, and showed no significant changes at least for 20 h. Treatment with Triton X-100 increased p53 immunoreactivity throughout the cell cycle. Octoxynol 164-176 P53 Homo sapiens 187-190 7845670-8 1995 In both assays, complex formation with E6 was mediated through the amino-terminal 345 amino acids of p53 without a specific requirement for its C-terminus. Polyurethane Y-290 39-41 P53 Homo sapiens 101-104 7597296-5 1995 Analysis of p53 gene showed mutation only in one case of mycosis fungoides in tumoral stage, at codon 163 of p53 gene (TAC-->CAC; Tyr--> Asp). Aspartic Acid 143-146 P53 Homo sapiens 12-15 7597296-5 1995 Analysis of p53 gene showed mutation only in one case of mycosis fungoides in tumoral stage, at codon 163 of p53 gene (TAC-->CAC; Tyr--> Asp). Aspartic Acid 143-146 P53 Homo sapiens 109-112 7923116-4 1994 Induction of p53 is also abnormal in AT cells following treatment with methylmethanesulfonate and bleomycin but appears relatively normal following treatment with UV-C irradiation or the topoisomerase inhibitors, etoposide and camptothecin. Methyl Methanesulfonate 71-93 P53 Homo sapiens 13-16 7923116-4 1994 Induction of p53 is also abnormal in AT cells following treatment with methylmethanesulfonate and bleomycin but appears relatively normal following treatment with UV-C irradiation or the topoisomerase inhibitors, etoposide and camptothecin. Bleomycin 98-107 P53 Homo sapiens 13-16 7926727-5 1994 Rather, the hydrophobic amino acid residues Leu-22 and Trp-23 of human p53 are both required for trans-activation activity, binding to the adenovirus E1B 55-kD protein and the human mdm-2-p53 protein in vitro. Leucine 44-47 P53 Homo sapiens 71-74 7926727-5 1994 Rather, the hydrophobic amino acid residues Leu-22 and Trp-23 of human p53 are both required for trans-activation activity, binding to the adenovirus E1B 55-kD protein and the human mdm-2-p53 protein in vitro. Leucine 44-47 P53 Homo sapiens 188-191 7926727-6 1994 In addition, hydrophobic residues Leu-14 and Phe-19 are crucial for the interactions between p53 and human mdm-2 (hdm-2). Leucine 34-37 P53 Homo sapiens 93-96 8014109-6 1994 These data indicate that part of the IQ-induced HCCs in nonhuman primates may involve inactivation of the p53 gene and suggest that IQ and possibly other heterocyclic amines may participate in human carcinogenesis by a similar mechanism. Amines 167-173 P53 Homo sapiens 106-109 8161788-5 1994 Morphological analysis, flow-cytometric determination of granulocytic or monocytic surface markers, and ability to reduce nitroblue tetrazolium (NBT) demonstrated that expression of exogenous wild-type p53 gene in HL-60 cells induces differentiation through the granulocytic pathway. Nitroblue Tetrazolium 122-143 P53 Homo sapiens 202-205 8161788-5 1994 Morphological analysis, flow-cytometric determination of granulocytic or monocytic surface markers, and ability to reduce nitroblue tetrazolium (NBT) demonstrated that expression of exogenous wild-type p53 gene in HL-60 cells induces differentiation through the granulocytic pathway. Nitroblue Tetrazolium 145-148 P53 Homo sapiens 202-205 8246608-2 1993 Sequencing of the p53 gene in the K562 cell line demonstrated a mutation in exon 5 characterized by a single base insertion (cytosine) between codons 135 and 136. Cytosine 125-133 P53 Homo sapiens 18-21 1396069-0 1992 [Overexpression of p53 protein in human spontaneous esophageal carcinoma and fetal esophageal carcinoma induced by N-methyl-N-benzylnitrosamine (NMBzA)]. N-methyl-N-benzylnitrosamine 115-143 P53 Homo sapiens 19-22 1396069-0 1992 [Overexpression of p53 protein in human spontaneous esophageal carcinoma and fetal esophageal carcinoma induced by N-methyl-N-benzylnitrosamine (NMBzA)].

Guanine 54-62 P53 Homo sapiens 3-6 10490506-14 1999 In p53 and ras genes, the frequency of methylation of guanines parallels the frequency of mutations of those same guanines in lung cancer. Guanine 114-122 P53 Homo sapiens 3-6 10487521-2 1999 We have previously reported that a mutation at codon 273, p53-273L (Arg --> Leu), suppresses cell growth despite its having no p53-specific transactivation activity. Leucine 79-82 P53 Homo sapiens 58-61 10446162-2 1999 It has recently been shown that BPDE preferentially modifies the guanine in methylated 5"-CpG-3" sequences in the human p53 gene, providing one explanation for why these sites are mutational hot spots. Guanine 65-72 P53 Homo sapiens 120-123 10470656-8 1999 However, in the p53 negative subgroup (n = 36), AI and BAX scores were higher and BCL-2 scores lower in the 5"-DFUR group than in the control group (P = 0.006, 0.008 and 0.050, respectively). 5"-dfur 108-115 P53 Homo sapiens 16-19 10470656-12 1999 CONCLUSIONS: Preoperative treatment with 5"-DFUR induced apoptosis and changes in BCL-2 and BAX expression in p53 negative breast cancers. 5"-dfur 41-48 P53 Homo sapiens 110-113 10383141-0 1999 Implication of p53 in growth arrest and apoptosis induced by the synthetic retinoid CD437 in human lung cancer cells. Retinoids 75-83 P53 Homo sapiens 15-18 10403664-0 1999 Methyl methanesulfonate and hydrogen peroxide differentially regulate p53 accumulation in hepatoblastoma cells. Methyl Methanesulfonate 0-23 P53 Homo sapiens 70-73 10403664-3 1999 Since the mechanisms by which cellular DNA damaged by different DNA-damaging chemicals may not be the same, we studied the involvement of p53, Bcl-2 and Bax in apoptosis induced by methyl methanesulfonate (MMS) and hydrogen peroxide (H2O2). Methyl Methanesulfonate 206-209 P53 Homo sapiens 138-141 10403664-5 1999 At non-lethal doses, both H2O2 and MMS induced high level of p53 protein accumulation. Methyl Methanesulfonate 35-38 P53 Homo sapiens 61-64 10226945-3 1999 One tumor sample (case 23) showed a mis-sense point mutation at codon 177, changing CCC to CTC, which resulted in a substitution of proline to leucine in the p53 protein. Leucine 143-150 P53 Homo sapiens 158-161 10096970-1 1999 BACKGROUND: The cytotoxic effects of cisplatin and anthracyclins have been attributed to apoptosis induction, which has been recognized as a major function of the TP53 gene. anthracyclins 51-64 P53 Homo sapiens 163-167 10190503-0 1999 Restoration of mutant TP53 to normal TP53 function by glycerol as a chemical chaperone. Glycerol 54-62 P53 Homo sapiens 22-26 10190503-0 1999 Restoration of mutant TP53 to normal TP53 function by glycerol as a chemical chaperone. Glycerol 54-62 P53 Homo sapiens 37-41 10190503-5 1999 We examined whether glycerol can act as a chemical chaperone to correct the mutant TP53 conformation. Glycerol 20-28 P53 Homo sapiens 83-87 10190503-9 1999 These cells showed similar CDKN1A expression when heated in the presence of glycerol at 0.6 or 1.2 M. These results suggest that glycerol is effective in restoring several TP53 mutants to normal TP53 function, leading to normal CDKN1A expression after heat stress. Glycerol 129-137 P53 Homo sapiens 172-176 10190503-9 1999 These cells showed similar CDKN1A expression when heated in the presence of glycerol at 0.6 or 1.2 M. These results suggest that glycerol is effective in restoring several TP53 mutants to normal TP53 function, leading to normal CDKN1A expression after heat stress. Glycerol 129-137 P53 Homo sapiens 195-199 10096571-4 1999 Fas-mediated cell death in these cell lines is p53-independent. ammonium ferrous sulfate 0-3 P53 Homo sapiens 47-50 10082992-4 1999 Northern blot analysis revealed that quercetin induced the increases in c-fos and p21WAF1CIP1 mRNA levels within 2 h. The expression of p21 protein was also enhanced, while p53 mRNA and protein levels were not affected by quercetin. Quercetin 37-46 P53 Homo sapiens 173-176 10082992-5 1999 These results suggest that quercetin-induced apoptosis is associated with the increase in c-fos mRNA level and the upregulation of p21 mRNA and protein expression, probably in a p53-independent pathway. Quercetin 27-36 P53 Homo sapiens 178-181 9927185-3 1999 When treated with N-(phosphonacetyl)-L-aspartate (PALA), which inhibits pyrimidine nucleotide synthesis, leading to synthesis of damaged DNA from highly unbalanced dNTP pools, p53-null cells enter mitosis after they have completed DNA replication, but cells with wild-type p53 do not, revealing that p53 also mediates a checkpoint that monitors the quality of newly replicated DNA. sparfosic acid 18-48 P53 Homo sapiens 176-179 9927185-3 1999 When treated with N-(phosphonacetyl)-L-aspartate (PALA), which inhibits pyrimidine nucleotide synthesis, leading to synthesis of damaged DNA from highly unbalanced dNTP pools, p53-null cells enter mitosis after they have completed DNA replication, but cells with wild-type p53 do not, revealing that p53 also mediates a checkpoint that monitors the quality of newly replicated DNA. sparfosic acid 18-48 P53 Homo sapiens 273-276 9927185-3 1999 When treated with N-(phosphonacetyl)-L-aspartate (PALA), which inhibits pyrimidine nucleotide synthesis, leading to synthesis of damaged DNA from highly unbalanced dNTP pools, p53-null cells enter mitosis after they have completed DNA replication, but cells with wild-type p53 do not, revealing that p53 also mediates a checkpoint that monitors the quality of newly replicated DNA. sparfosic acid 18-48 P53 Homo sapiens 273-276 10412949-9 1999 RESULTS: p53 Ad combined with cisplatin, doxorubicin, 5-fluorouracil, methotrexate, or etoposide inhibited cell proliferation more effectively than chemotherapy alone in SCC-9 head and neck, SCC-15 head and neck, SCC-25 head and neck, SK-OV-3 ovarian, DU-145 prostate, MDA-MB-468 breast, and MDA-MB-231 breast tumor cells. Methotrexate 70-82 P53 Homo sapiens 9-12 10626228-0 1999 Localization of chloroacetaldehyde-induced DNA damage in human p53 gene by DNA polymerase fingerprint analysis. chloroacetaldehyde 16-34 P53 Homo sapiens 63-66 10626228-1 1999 Chloroacetaldehyde (CAA) reacts with DNA bases, forming hydroxyethano derivatives of different stability, which are subsequently converted into etheno (epsilon) adducts: epsilon A, epsilon C, epsilon G. DNA polymerase fingerprint analysis was used to study the distribution of CAA-induced modifications in the p53 sequence. chloroacetaldehyde 0-18 P53 Homo sapiens 310-313 10626228-1 1999 Chloroacetaldehyde (CAA) reacts with DNA bases, forming hydroxyethano derivatives of different stability, which are subsequently converted into etheno (epsilon) adducts: epsilon A, epsilon C, epsilon G. DNA polymerase fingerprint analysis was used to study the distribution of CAA-induced modifications in the p53 sequence. chloroacetaldehyde 20-23 P53 Homo sapiens 310-313 10626228-2 1999 A plasmid bearing cDNA containing the human p53 gene was reacted in vitro with CAA, then dehydrated for conversion of hydroxyethano into etheno adducts, and primer extension by T7 DNA polymerase in the presence of four dNTPs was performed. chloroacetaldehyde 79-82 P53 Homo sapiens 44-47 10626228-9 1999 In exons 5-8 of p53, 143 out of 500 sites appeared to be damaged by CAA, with four particularly densely modified regions between codons 135-147, 218-222, 234-255 and 284-292. chloroacetaldehyde 68-71 P53 Homo sapiens 16-19 11601009-10 1999 CONCLUSION: Codon 172 mutant (Arg-->Leu) p53 genomic DNA exhibited a strong suppressive transfecting effects on carcinoma cell, so it is a possible candidate to be used in cancer gene therapy. Leucine 39-42 P53 Homo sapiens 44-47 9875290-6 1998 We found that DU-86, a duocarmycin derivative which alkylates DNA, bound ssDNA and enhanced the DNA binding activity of the p53 C-terminus. du 14-16 P53 Homo sapiens 124-127 9875290-7 1998 DU-86 weakened p53-mediated catalysis of complementary ssDNA renaturation. du 0-2 P53 Homo sapiens 15-18 9881702-1 1998 Sequence-dependent formation and lack of repair of polycyclic aromatic hydrocarbon-induced DNA adducts correlates well with the positions of p53 mutational hotspots in smoking-related lung cancers (Denissenko et al, 1996, 1998). Polycyclic Aromatic Hydrocarbons 51-82 P53 Homo sapiens 141-144 14646475-8 1998 Two other agents known to induce apoptosis, vinblastine and actinomycin D, induced a similar pattern of acidic p53 species as that observed for 2-MeOE2. Vinblastine 44-55 P53 Homo sapiens 111-114 9823951-15 1998 In contrast, four of five Fas+/Fas-resistant (R) lines were wt-p53+/Bcl-2+; the exception was p53-null/Bcl-2- but expressed a low level of Fas (150 MESF). ammonium ferrous sulfate 26-29 P53 Homo sapiens 63-66 9823951-15 1998 In contrast, four of five Fas+/Fas-resistant (R) lines were wt-p53+/Bcl-2+; the exception was p53-null/Bcl-2- but expressed a low level of Fas (150 MESF). ammonium ferrous sulfate 31-34 P53 Homo sapiens 63-66 9823951-15 1998 In contrast, four of five Fas+/Fas-resistant (R) lines were wt-p53+/Bcl-2+; the exception was p53-null/Bcl-2- but expressed a low level of Fas (150 MESF). ammonium ferrous sulfate 31-34 P53 Homo sapiens 63-66 9823951-18 1998 These results suggest that some pediatric ALL cells expressing mt-p53+ may be sensitive to Fas-mediated apoptosis due to high levels of Fas expression and lack of Bcl-2, and further suggest that molecular methods of activating Fas may be useful for therapy of refractory ALL with the Fas+/mt-p53+ phenotype. ammonium ferrous sulfate 91-94 P53 Homo sapiens 66-69 9823951-18 1998 These results suggest that some pediatric ALL cells expressing mt-p53+ may be sensitive to Fas-mediated apoptosis due to high levels of Fas expression and lack of Bcl-2, and further suggest that molecular methods of activating Fas may be useful for therapy of refractory ALL with the Fas+/mt-p53+ phenotype. ammonium ferrous sulfate 91-94 P53 Homo sapiens 292-295 9765154-5 1998 p53 also induced Fas-FADD binding and transiently sensitized cells to Fas-induced apoptosis. ammonium ferrous sulfate 17-20 P53 Homo sapiens 0-3 9879152-0 1998 13-cis-retinoic acid and interferon-alpha 2a therapy in locally advanced squamous cell carcinoma of the cervix: p53 alteration, proliferating cell nuclear antigen expression and angiogenesis response. Isotretinoin 0-20 P53 Homo sapiens 112-115 9771923-10 1998 The status of the tumor suppressor gene p53 was analyzed in methotrexate sensitive and resistant clones. Methotrexate 60-72 P53 Homo sapiens 40-43 9771923-11 1998 In all the methotrexate resistant clones analyzed, the western blots indicated that the p53 protein was still present and transcriptionally competent, as measured by its capacity to stimulate transcription of the p21waf1/cip1 gene following UVB irradiation. Methotrexate 11-23 P53 Homo sapiens 88-91 9771923-13 1998 However, this induction of p53 accumulation by estrogens failed to stimulate the transcription of p21waf1/cip1, which indicates that a transcriptionally inactive form of p53 accumulated in methotrexate resistant cells. Methotrexate 189-201 P53 Homo sapiens 170-173 9790785-8 1998 Exons 2 through 11 of the p53 gene were analyzed by direct DNA sequencing, revealing a homozygous mutation at codon 281 in exon 8, GAC to CAC (Asp-->His). Aspartic Acid 143-146 P53 Homo sapiens 26-29 9719464-5 1998 This apoptotic cell death with p21 induction was also observed in the Hep 3B cells lacking functional p53 after exposure to C6-ceramide. N-caproylsphingosine 124-135 P53 Homo sapiens 102-105 9610721-5 1998 The initial analysis showed NY-CO-13 to be a mutated version of the p53 tumor suppressor gene. ny-co-13 28-36 P53 Homo sapiens 68-71 9605744-3 1998 Using a UvrABC incision method, we have found that cytosine methylation greatly enhances guanine alkylation at all CpG sites in the p53 gene by a variety of carcinogens, including benzo(a)pyrene diol epoxide, benzo(g)chrysene diol epoxide, aflatoxin B1 8,9-epoxide, and N-acetoxy-2-acetylaminofluorene. Cytosine 51-59 P53 Homo sapiens 132-135 9605744-3 1998 Using a UvrABC incision method, we have found that cytosine methylation greatly enhances guanine alkylation at all CpG sites in the p53 gene by a variety of carcinogens, including benzo(a)pyrene diol epoxide, benzo(g)chrysene diol epoxide, aflatoxin B1 8,9-epoxide, and N-acetoxy-2-acetylaminofluorene. Guanine 89-96 P53 Homo sapiens 132-135 9591783-4 1998 Based on these results, we propose a mechanism by which PAb1620 can allosterically inhibit p53 binding to DNA through an indirect interaction between the antibody binding site and the L1 loop (amino acids 112-124) of p53, which is a component of the DNA binding region. pab1620 56-63 P53 Homo sapiens 217-220 9528853-5 1998 By 8 days after a brief exposure to DNA strand breaking agents, bleomycin or actinomycin D, p53 protein is at baseline levels, while the p53 transactivation level is only slightly above its baseline. Bleomycin 64-73 P53 Homo sapiens 92-95 9448010-4 1998 OA also induced RER accumulation of the IC protein p53/p58 via an IC-RER recycling pathway which was resistant to OA and inhibited by the G protein activator aluminium fluoride. aluminum fluoride 158-176 P53 Homo sapiens 51-54 9388195-0 1997 Activation of adenomatous polyposis coli (APC) gene expression by the DNA-alkylating agent N-methyl-N"-nitro-N-nitrosoguanidine requires p53.

Vinblastine 163-174 P53 Homo sapiens 42-45 9389932-8 1997 Both m-AMCA and amsacrine induced p53 protein expression in proliferating but not in non-proliferating H460 cells, and induced p21WAF1 regardless of proliferation status. methyl-N-(4-(9-acridinylamino)-2-methoxyphenyl)carbamate 5-11 P53 Homo sapiens 34-37 9308722-5 1997 Only 2 of 22 (9%) patients harbored a p53 mutation (which, interestingly, were identical and consisted of a codon 259 Asp --> His exchange), despite diffuse overexpression of high levels of nuclear p53 protein in most cases. Aspartic Acid 118-121 P53 Homo sapiens 38-41 9266962-0 1997 Transcriptional squelching by ectopic expression of E2F-1 and p53 is alleviated by proteasome inhibitors MG-132 and lactacystin. lactacystin 116-127 P53 Homo sapiens 62-65 9266962-3 1997 Although the proteasome inhibitors MG-132 and lactacystin markedly increased the level of expression of E2F-1 and p53, these inhibitors completely alleviated squelching by both proteins. lactacystin 46-57 P53 Homo sapiens 114-117 9244359-9 1997 Activation of p53 by PAb421 also results in enhanced transactivation in vitro. pab421 21-27 P53 Homo sapiens 14-17 9815762-13 1997 Eighty-three percent of patients having low p53 expression had up-regulation of RAR-beta mRNA after isotretinoin therapy, compared with 22% of patients with high p53 expression (P = 0.003). Isotretinoin 100-112 P53 Homo sapiens 44-47 9815762-14 1997 We correlated baseline p53 protein expression with RAR-beta modulation and clinical responses to isotretinoin therapy. Isotretinoin 97-109 P53 Homo sapiens 23-26 9815762-17 1997 The patients with high p53 protein expression and either no change or down-regulation of RAR-beta had a response rate of only 14% to isotretinoin therapy.

Retinoids 186-195 P53 Homo sapiens 61-64 9112432-5 1997 Treatment of these drug-resistant cells with non-toxic doses of the resistance-inducing drug vinblastin induced a strong increase in p53 protein and mRNA but was ineffective on mdm2 protein expression, or mdr1 mRNA expression. Vinblastine 93-103 P53 Homo sapiens 133-136 9008206-4 1997 Using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling, internucleosomal DNA ladders and flow cytometry, we correlated observed changes in p53 expression with the induction of apoptosis at low, intermediate and high doses of UVB radiation. deoxyuridine triphosphate 53-78 P53 Homo sapiens 181-184 9107076-0 1997 Bcl-2 protein expression and p53 gene mutation in chronic lymphocytic leukemia: correlation with in vitro sensitivity to chlorambucil and purine analogs. purine 138-144 P53 Homo sapiens 29-32 9038605-4 1996 In 4 cases, the mutations lead to distinct changes in the primary or secondary structure of the protein (cysteine-->tyrosine, proline-->leucine) and were associated with marked accumulation of p53 protein. Leucine 142-149 P53 Homo sapiens 199-202 9042236-0 1996 Effects of microtubule inhibitors-taxol, vinblastine and estramustine on the growth and p53 gene expression in the hormone independent human prostatic JCA-1 cells. Vinblastine 41-52 P53 Homo sapiens 88-91 19727814-0 2010 P53 and p38 MAPK pathways are involved in MONCPT-induced cell cycle G2/M arrest in human non-small cell lung cancer A549. 10-methoxy-9-nitrocamptothecin 42-48 P53 Homo sapiens 0-3 8900110-7 1996 Cells lacking the c-abl gene also responded to ara-C and MMS with increases in p53 levels and induction of p21. Methyl Methanesulfonate 57-60 P53 Homo sapiens 79-82 19727814-8 2010 Moreover, down-regulation of p-AKT in A549 cells was seen after treated with 100.0 nM MONCPT for 12-48 h. Over-expression of p53 and p21 in A549 cells treated with MONCPT was observed in time-dependent manner. 10-methoxy-9-nitrocamptothecin 86-92 P53 Homo sapiens 125-128 19727814-8 2010 Moreover, down-regulation of p-AKT in A549 cells was seen after treated with 100.0 nM MONCPT for 12-48 h. Over-expression of p53 and p21 in A549 cells treated with MONCPT was observed in time-dependent manner. 10-methoxy-9-nitrocamptothecin 164-170 P53 Homo sapiens 125-128 8824527-12 1996 At this passage, mutation of the p53 gene was detected at codon 273 of exon 8, with G to T conversion (Arg to Leu). Leucine 110-113 P53 Homo sapiens 33-36 19727814-9 2010 When wild type p53 expression was specifically inhibited by RNA-interference, A549 cells treated with MONCPT delayed the onset of G2/M arrest; meanwhile p-ERK and Cdc2 were up-regulated while p21 and CDK7 were down-regulated in A549 cells treated with MONCPT and p53 SiRNA transfection in contrast to cells treated with 100.0 nM MONCPT alone. 10-methoxy-9-nitrocamptothecin 102-108 P53 Homo sapiens 15-18 8763853-0 1996 The interaction of taxol and vinblastine with radiation induction of p53 and p21 WAF1/CIP1. Vinblastine 29-40 P53 Homo sapiens 69-72 19727814-9 2010 When wild type p53 expression was specifically inhibited by RNA-interference, A549 cells treated with MONCPT delayed the onset of G2/M arrest; meanwhile p-ERK and Cdc2 were up-regulated while p21 and CDK7 were down-regulated in A549 cells treated with MONCPT and p53 SiRNA transfection in contrast to cells treated with 100.0 nM MONCPT alone. 10-methoxy-9-nitrocamptothecin 102-108 P53 Homo sapiens 263-266 8763853-4 1996 We examined the induction of p53 and its downstream target, p21WAF1/CIP1, by the microtubule active agents taxol and vinblastine with radiation. Vinblastine 117-128 P53 Homo sapiens 29-32 8763853-5 1996 An increase in induction of both p53 and p21 WAF1/CIP1 was demonstrated when radiation was added to either taxol or vinblastine treatment. Vinblastine 116-127 P53 Homo sapiens 33-36 19727814-9 2010 When wild type p53 expression was specifically inhibited by RNA-interference, A549 cells treated with MONCPT delayed the onset of G2/M arrest; meanwhile p-ERK and Cdc2 were up-regulated while p21 and CDK7 were down-regulated in A549 cells treated with MONCPT and p53 SiRNA transfection in contrast to cells treated with 100.0 nM MONCPT alone. 10-methoxy-9-nitrocamptothecin 252-258 P53 Homo sapiens 15-18 8706243-3 1996 Sublines that were resistant to melphalan, pyrazafurin, mitoxantrone, etoposide and PALA all retained expression of wild-type p53. Melphalan 32-41 P53 Homo sapiens 126-129 19727814-9 2010 When wild type p53 expression was specifically inhibited by RNA-interference, A549 cells treated with MONCPT delayed the onset of G2/M arrest; meanwhile p-ERK and Cdc2 were up-regulated while p21 and CDK7 were down-regulated in A549 cells treated with MONCPT and p53 SiRNA transfection in contrast to cells treated with 100.0 nM MONCPT alone. 10-methoxy-9-nitrocamptothecin 252-258 P53 Homo sapiens 15-18 8706243-4 1996 Methotrexate-resistant MCF-7 cells were unusual heterozygotes that expressed a wild-type and dominant, in-frame p53 deletion mutant and the doxorubicin-resistant cells expressed only mutant p53. Methotrexate 0-12 P53 Homo sapiens 112-115 8706243-4 1996 Methotrexate-resistant MCF-7 cells were unusual heterozygotes that expressed a wild-type and dominant, in-frame p53 deletion mutant and the doxorubicin-resistant cells expressed only mutant p53. Methotrexate 0-12 P53 Homo sapiens 190-193 19727814-11 2010 Treatment with p38 mitogen-activated protein kinase (MAPK) SiRNA obviously inhibited p38 MAPK and delayed the G2/M arrest induced by 50.0 nM MONCPT after 48 h. CONCLUSION: Cell cycle regulators, AKT, p53, and MAPK, as therapeutic targets for MONCPT to induce cell cycle G2/M arrest in the context of anticancer therapy. 10-methoxy-9-nitrocamptothecin 141-147 P53 Homo sapiens 200-203 19892797-7 2010 Cokeoven workers were heavily exposed to PAHs (79% exceeded the urinary 1-pyrenol biological exposure index) and exhibited lower TL (P = 0.038) than controls, as well as higher levels of genetic and chromosomal alterations [i.e. anti-BPDE-DNA adduct and MN (P < 0.0001)] and epigenetic changes [i.e. p53 gene-specific promoter and global methylation (P <or= 0.001)]. Polycyclic Aromatic Hydrocarbons 41-45 P53 Homo sapiens 303-306 8800591-6 1996 Alterations in exons 4, 5 and 7 of the p53 gene in patients with functional adrenal tumours, including aldosterone-producing adenomas, have recently been described. Aldosterone 103-114 P53 Homo sapiens 39-42 8666362-6 1996 Three (50%) BPB and WDFA stained for p53 and five (83%) for MDM2. bpb 12-15 P53 Homo sapiens 37-40 20465648-9 2010 Slight but significant difference between A/B for p53 with major reduction post isotretinoin [0.66+/-0.31 vs. 0.94+/-0.34 respectively (P = 0.04) was observed. Isotretinoin 80-92 P53 Homo sapiens 50-53 8669168-8 1996 RESULTS: Freeze substituted cells that were fixed with methanol/ether and stored for more than six months retained strong p53 positivity, as strong as that of the control cells, which had been fixed and stored in methanol. Methanol 55-63 P53 Homo sapiens 122-125 8669168-8 1996 RESULTS: Freeze substituted cells that were fixed with methanol/ether and stored for more than six months retained strong p53 positivity, as strong as that of the control cells, which had been fixed and stored in methanol. Ether 64-69 P53 Homo sapiens 122-125 20465648-12 2010 The role of ultra-violet induced p53 mutation in skin carcinogenesis reinforces retinoids chemoprevention. Retinoids 80-89 P53 Homo sapiens 33-36 8622881-3 1996 A specific incorporation of the p53 gene with ACN53 reduced 3 (deleted p53 gene) cells was observed. acn53 46-51 P53 Homo sapiens 32-35 19913028-8 2010 Destabilizing mutations cause DBD to misfold when it is part of the p53 tetramer, but not when it is monomeric. dbd 30-33 P53 Homo sapiens 68-71 8622881-3 1996 A specific incorporation of the p53 gene with ACN53 reduced 3 (deleted p53 gene) cells was observed. acn53 46-51 P53 Homo sapiens 71-74 19955567-6 2010 Furthermore, we characterize for the first time the binding behavior of Pifithrin-mu, a specific small molecule inhibitor of the p53-BclxL interaction, and present a structural model of the protein-ligand complex. pifithrin 72-81 P53 Homo sapiens 129-132 8590759-1 1995 The effects of exogenous human p53 and its various mutants (Ala-141, His-175, His-194, Trp-248, His-273) on two key enzymes of purine uptake, adenosine deaminase (AD) and hypoxanthine phosphoribosyl transferase (HPRT), has been studied in Rat 1 immortalized fibroblasts and their sublines transformed by N-RAS or v-mos oncogenes. purine 127-133 P53 Homo sapiens 31-34 20006625-10 2010 Results of FAK promoter activity and ChIP assays in A549 and H1299 cells indicated that bortezomib suppressed FAK activity through a p53-independent pathway. Bortezomib 88-98 P53 Homo sapiens 133-136 7586163-5 1995 The results in Salmonella are consistent with a role for the PAH component of cigarette smoke in the base-substitution specificity found in the p53 gene of smoking-associated lung tumors. Polycyclic Aromatic Hydrocarbons 61-64 P53 Homo sapiens 144-147 20096120-0 2010 Cancer cell sensitivity to bortezomib is associated with survivin expression and p53 status but not cancer cell types. Bortezomib 27-37 P53 Homo sapiens 81-84 8579493-1 1995 The ability of exogenous p53 tumor-suppressor and activated N-PAS oncogene to influence differentiation state of human colon carcinoma LIM 1215 cells and their derivatives with acquired resistance to actinomycin D or methotrexate was analysed Introduction of retroviral construct expressing human wild-type (wt) p53 into LIM 1215 cells induced electron microscopic manifestations of enterocytic differentiation, i.e. caused an increase in the numbers of cells with microvilli, desmosomes and glandular-like lumens. Methotrexate 217-229 P53 Homo sapiens 25-28 20096120-5 2010 RESULTS: We found that cancer cells with wild type p53 show a low level expression of survivin and are sensitive to treatment with bortezomib, while cancer cells with a mutant or null p53 show a high level expression of survivin and are resistant to bortezomib-mediated apoptosis induction. Bortezomib 131-141 P53 Homo sapiens 51-54 8579493-7 1995 Comparison of expression of different electron microscopic features of cell differentiation and CEA expression in cell sublines selected for methotrexate-resistance and/or expressing exogenous constructs allows to suppose that p53 tumor-suppressor, PAS oncogene and dhfr gene amplification may lead to somewhat distinct differentiation states. Methotrexate 141-153 P53 Homo sapiens 227-230 20096120-5 2010 RESULTS: We found that cancer cells with wild type p53 show a low level expression of survivin and are sensitive to treatment with bortezomib, while cancer cells with a mutant or null p53 show a high level expression of survivin and are resistant to bortezomib-mediated apoptosis induction. Bortezomib 250-260 P53 Homo sapiens 51-54 20096120-7 2010 We further noted that modulation of survivin expression by bortezomib is dependent on p53 status but independent of cancer cell types. Bortezomib 59-69 P53 Homo sapiens 86-89 19629643-3 2010 After treatment of cells with methyl methanesulfonate (MMS), Apak is phosphorylated by ATM kinase and dissociates from p53, resulting in p53 activation and induction of apoptosis. Methyl Methanesulfonate 30-53 P53 Homo sapiens 119-122 19629643-3 2010 After treatment of cells with methyl methanesulfonate (MMS), Apak is phosphorylated by ATM kinase and dissociates from p53, resulting in p53 activation and induction of apoptosis. Methyl Methanesulfonate 30-53 P53 Homo sapiens 137-140 7630633-0 1995 p53 independent G0/G1 arrest and apoptosis induced by a novel retinoid in human breast cancer cells. Retinoids 62-70 P53 Homo sapiens 0-3 19629643-3 2010 After treatment of cells with methyl methanesulfonate (MMS), Apak is phosphorylated by ATM kinase and dissociates from p53, resulting in p53 activation and induction of apoptosis. Methyl Methanesulfonate 55-58 P53 Homo sapiens 119-122 7630633-8 1995 Thus AHPN represents a novel retinoid that induces G0/G1 arrest and apoptosis via a unique pathway which appears to involve activation of known downstream effectors of p53 in a p53-independent manner. Retinoids 29-37 P53 Homo sapiens 168-171 19629643-3 2010 After treatment of cells with methyl methanesulfonate (MMS), Apak is phosphorylated by ATM kinase and dissociates from p53, resulting in p53 activation and induction of apoptosis. Methyl Methanesulfonate 55-58 P53 Homo sapiens 137-140 7790313-3 1995 Immunostaining revealed nuclear accumulation of p53 within 6 h after various stresses [heat shock, osmotic shock, heavy metal (Cd), blockers of the cellular respiratory system (NaN3), amino acid analogues (azetidine and canavanine), an inhibitor of protein synthesis (puromycin), and oxygen free radicals (H2O2)]. Puromycin 268-277 P53 Homo sapiens 48-51 21499441-6 2010 Both, NPM and NCL interact with p53 and hinder its phosphorylation at Serine 15 in response to bleomycin. Bleomycin 95-104 P53 Homo sapiens 32-35 19934289-8 2009 CONCLUSIONS: This differential response of MM versus epithelial carcinomas to combination of nutlin-3 with bortezomib sheds new light on the role of p53 in bortezomib-induced apoptosis. Bortezomib 156-166 P53 Homo sapiens 149-152 19548002-0 2009 Adenovirally mediated p53 overexpression diversely influence the cell cycle of HEp-2 and CAL 27 cell lines upon cisplatin and methotrexate treatment. Methotrexate 126-138 P53 Homo sapiens 22-25 7805028-2 1995 These p53 analyses were included in a prospective trial of the retinoid isotretinoin (1.5 mg/kg/day for 3 months) in 40 patients (45 oral premalignant lesions). Retinoids 63-71 P53 Homo sapiens 6-9 7805028-8 1995 An inverse relationship occurred between the levels of accumulated p53 protein and response to isotretinoin (P = 0.006). Isotretinoin 95-107 P53 Homo sapiens 67-70 19548002-7 2009 RESULTS: In CAL 27 cells overexpression of p53 completely abrogated high S phase content observed in methotrexate-treated cells into a G1 and slight G2 arrest, while it sustained G2 arrest of the cells treated with cisplatin, along with the reduction of DNA synthesis and cyclin B1 expression. Methotrexate 101-113 P53 Homo sapiens 43-46 19548002-8 2009 On the other hand, in HEp-2 cell line p53 overexpression slightly slowed down the progression through S phase in cells treated with methotrexate, decreased the cyclin B1 expression only after 24 h, and failed to sustain the G2 arrest after treatment with cisplatin alone. Methotrexate 132-144 P53 Homo sapiens 38-41 7966288-5 1994 Two conformation-specific anti-p53 monoclonal antibodies were used to dissect the phage-p53 interaction, the phage were found to preferentially bind the PAb1620-p53 conformation rather than the PAb240-p53 conformation. pab1620 153-160 P53 Homo sapiens 31-34 7966288-5 1994 Two conformation-specific anti-p53 monoclonal antibodies were used to dissect the phage-p53 interaction, the phage were found to preferentially bind the PAb1620-p53 conformation rather than the PAb240-p53 conformation. pab1620 153-160 P53 Homo sapiens 88-91 7966288-5 1994 Two conformation-specific anti-p53 monoclonal antibodies were used to dissect the phage-p53 interaction, the phage were found to preferentially bind the PAb1620-p53 conformation rather than the PAb240-p53 conformation. pab1620 153-160 P53 Homo sapiens 88-91 7966288-5 1994 Two conformation-specific anti-p53 monoclonal antibodies were used to dissect the phage-p53 interaction, the phage were found to preferentially bind the PAb1620-p53 conformation rather than the PAb240-p53 conformation. pab1620 153-160 P53 Homo sapiens 88-91 19548002-10 2009 CONCLUSIONS: This study demonstrates that adenovirally mediated p53 overexpression at sub-cytotoxic levels enhanced the activity of low doses of cisplatin and methotrexate in HEp-2 and CAL 27 cells through changes in the cell cycle. Methotrexate 159-171 P53 Homo sapiens 64-67 19555669-0 2009 Transcriptional down-regulation of Bcl-2 by vinorelbine: identification of a novel binding site of p53 on Bcl-2 promoter. Vinorelbine 44-55 P53 Homo sapiens 99-102 7923176-11 1994 p53 allelic amino acid variation with sequences coding for aspartic acid or asparagine was present in codon 61 in the variable region of exon 4 in both HCCs and nonneoplastic tissues of ground squirrels. Aspartic Acid 59-72 P53 Homo sapiens 0-3 8036011-0 1994 Oxy-radical induced mutagenesis of hotspot codons 248 and 249 of the human p53 gene. oxy-radical 0-11 P53 Homo sapiens 75-78 19555669-5 2009 We report here that p53 contributes to vinorelbine-induced Bcl-2 down-regulation. Vinorelbine 39-50 P53 Homo sapiens 20-23 19713938-1 2009 The p53-inducible TIGAR protein functions as a fructose-2,6-bisphosphatase, promoting the pentose phosphate pathway and helping to lower intracellular reactive oxygen species (ROS). Pentosephosphates 90-107 P53 Homo sapiens 4-7 7946294-1 1994 A procedure for direct sequencing of the human p53 gene based on micro-dissection of frozen tumor tissue stained with methylene blue without prior fixation is described. Methylene Blue 118-132 P53 Homo sapiens 47-50 8061893-5 1994 IHC assays revealed nuclear p53 immunostaining in 53% of cases (32 of 60) with PAb1801, 38% (23 of 60) with PAb421, and 32% (19 of 60) with PAb240. pab421 108-114 P53 Homo sapiens 28-31 18930193-1 2009 OBJECTIVE: To determine whether the p53 codon 72 single nucleotide polymorphism, a change of the amino acid arginine (Arg) to proline (Pro) resulting from a single nucleotide mutation of guanine (G) to cytosine (C), has a clinically significant effect on implantation rate in fresh IVF cycles. Guanine 187-194 P53 Homo sapiens 36-39 8162591-0 1994 Quercetin mediates the down-regulation of mutant p53 in the human breast cancer cell line MDA-MB468. Quercetin 0-9 P53 Homo sapiens 49-52 8162591-4 1994 We have correlated these effects on cell proliferation with the observation that quercetin strongly inhibited, in a time- and dose-dependent fashion, the expression of the mutated p53 protein, which is the only form present at high levels in this cell line. Quercetin 81-90 P53 Homo sapiens 180-183 8162591-6 1994 Quercetin did not affect the steady-state mRNA levels of p53, but prevented the accumulation of newly synthesized p53 protein. Quercetin 0-9 P53 Homo sapiens 114-117 8162591-7 1994 This quercetin action appeared to be somewhat specific for p53 because the drug did not alter the amount of other proteins present in MDA-MB468 cells such as P-glycoprotein and did not prevent the induction of the synthesis of epidermal growth factor receptor in response to epidermal growth factor. Quercetin 5-14 P53 Homo sapiens 59-62 18930193-1 2009 OBJECTIVE: To determine whether the p53 codon 72 single nucleotide polymorphism, a change of the amino acid arginine (Arg) to proline (Pro) resulting from a single nucleotide mutation of guanine (G) to cytosine (C), has a clinically significant effect on implantation rate in fresh IVF cycles. Cytosine 202-210 P53 Homo sapiens 36-39 19452524-9 2009 The associations between lutein and tocopherol and TP53 and KRAS2 mutations were modified by IL6 genotype. Tocopherols 36-46 P53 Homo sapiens 51-55 8114714-4 1994 We exposed human cell lines containing wild-type p53 alleles to several different DNA-damaging agents and found that agents which rapidly induce DNA strand breaks, such as ionizing radiation, bleomycin, and DNA topoisomerase-targeted drugs, rapidly triggered p53 protein elevations. Bleomycin 192-201 P53 Homo sapiens 49-52 8114714-4 1994 We exposed human cell lines containing wild-type p53 alleles to several different DNA-damaging agents and found that agents which rapidly induce DNA strand breaks, such as ionizing radiation, bleomycin, and DNA topoisomerase-targeted drugs, rapidly triggered p53 protein elevations. Bleomycin 192-201 P53 Homo sapiens 259-262 20448956-0 2009 Oligobenzamide proteomimetic inhibitors of the p53-hDM2 protein-protein interaction. oligobenzamide 0-14 P53 Homo sapiens 47-50 8114714-6 1994 Furthermore, treatment of cells with the antimetabolite N(phosphonoacetyl)-L-aspartate (PALA) did not cause rapid p53 protein increases but resulted in delayed increases in p53 protein levels temporally correlated with the appearance of DNA strand breaks. sparfosic acid 56-86 P53 Homo sapiens 173-176 8108114-5 1994 T402DE-induced NHDF foci senesced at the same time as untransfected cells, but the equivalent LFS foci all had increased proliferative potentials, with the greatest increase being seen in clones that lost the wt p53 allele. t402de 0-6 P53 Homo sapiens 212-215 20448956-1 2009 Oligobenzamide inhibitors of the p53-hDM2 protein-protein interaction are described. oligobenzamide 0-14 P53 Homo sapiens 33-36 19579043-3 2009 At 5-10 muM concentrations, rhizochalin was effective as an inhibitor of the malignant transformation of JB6 P(+) Cl 41 cells or colony formation of human tumor cells, which exerted its action, at least in part, through the induction of p53-dependent apoptosis. rhizochalin 28-39 P53 Homo sapiens 237-240 7849743-4 1994 The high incidence of C-to-T transitions found in the p53 tumor-suppressor gene is attributed to the spontaneous deamination of 5-methylcytosine residues. 5-Methylcytosine 128-144 P53 Homo sapiens 54-57 19531487-2 2009 In the present study, a mass spectrometry-based approach was used to analyze the effects of cytosine methylation on the kinetics of AGT repair of O(6)-methyldeoxyguanosine (O(6)-Me-dG) adducts placed within frequently mutated 5"-CG-3" dinucleotides of the p53 tumor suppressor gene. Cytosine 92-100 P53 Homo sapiens 256-259 8302593-9 1994 The first detected electromobility shift of 32P-labelled DNA and was carried out in the presence of PAb421, which stabilises and supershifts p53-DNA complexes. pab421 100-106 P53 Homo sapiens 141-144 19531487-7 2009 In contrast, cytosine methylation within p53 codon 158 slightly increased the rate of O(6)-Me-dG repair by AGT. Cytosine 13-21 P53 Homo sapiens 41-44 19328766-4 2009 Deneddylase-1 (DEN1/NEDP1/SENP8) features a selective peptidase activity converting the proNEDD8 precursor to its mature form and an isopeptidase activity deconjugating NEDD8 from substrates such as cullins and p53. pronedd8 88-96 P53 Homo sapiens 211-214 8321226-4 1993 IR, UV radiation, and methylmethane sulfonate were found to induce p53 activity when a stably integrated reporter construct containing functional p53-binding sites was used and also in mobility shift assays with a p53-binding site from the GADD45 gene, and IR-inducible gene previously associated with growth arrest. Methyl Methanesulfonate 22-45 P53 Homo sapiens 67-70 8321226-4 1993 IR, UV radiation, and methylmethane sulfonate were found to induce p53 activity when a stably integrated reporter construct containing functional p53-binding sites was used and also in mobility shift assays with a p53-binding site from the GADD45 gene, and IR-inducible gene previously associated with growth arrest.

Quercetin 39-48 P53 Homo sapiens 144-147 17520098-8 2007 From our results it can be concluded that quercetin blocks cell cycle progression at G(1) phase and exerts its growth-inhibitory effect through the increase of Cdk inhibitors p21 and p27 and tumor suppressor p53 in HepG2.

Tantalum 103-106 P53 Homo sapiens 0-3 17662641-3 2007 We show that bleomycin-treated A549 cells exhibit: senescence-like cell morphology; a senescence-associated increase in SA-beta-galactosidase activity; cell cycle arrest; and upregulation of p53 and p21. Bleomycin 13-22 P53 Homo sapiens 191-194 17662641-6 2007 Our results support the hypothesis that downregulation of caveolin-1 expression affects bleomycin-induced cell cycle arrest and subsequent cellular senescence that is driven by p53 and p21.

Zidovudine 51-54 P53 Homo sapiens 83-86 16797627-5 2006 In this study, we show that AZT, cisplatin (CDDP) and docetaxel (DTX) all induce unique molecular responses in OVCAR-3 ovarian carcinoma cells carrying a mutated p53, while in A2780, ovarian carcinoma and MCF-7 breast carcinoma cells with wild type p53, all of these drugs cause similar p53 responses. Zidovudine 28-31 P53 Homo sapiens 162-165 16797627-5 2006 In this study, we show that AZT, cisplatin (CDDP) and docetaxel (DTX) all induce unique molecular responses in OVCAR-3 ovarian carcinoma cells carrying a mutated p53, while in A2780, ovarian carcinoma and MCF-7 breast carcinoma cells with wild type p53, all of these drugs cause similar p53 responses.

Nucleosides 0-10 P53 Homo sapiens 143-146 17065086-1 2006 Previously, we have found that activation of deoxycytidine kinase elicited by various DNA-damaging chemical agents could be prevented by BAPTA-AM, a cell-permeable calcium chelator or by pifithrin-alpha, a pharmacological inhibitor of p53. pifithrin 187-202 P53 Homo sapiens 235-238 15908180-7 2005 This synergistic activation of JNK/SAPK by TNF-alpha/IFN-gamma was also induced in insulin-expressing pancreatic islet cells, and increased ROS production and p53 level, which was significantly inhibited by SP600125. pyrazolanthrone 207-215 P53 Homo sapiens 159-162 16332175-2 2005 In the AD patients the increased levels of oxidized guanine were demonstrated in DNA, accompanied by the elevated expression of p53, Bax, PARP, and of a 85-kDa protein subunit as well as an augmented ratio of Bax:Bcl-2.

Fluvastatin 137-148 P53 Homo sapiens 13-16 16382051-4 2005 Colon cancer cell lines lacking p53 or Bax were sensitized by bortezomib, suggesting that neither p53 nor Bax levels were crucial for sensitization. Bortezomib 62-72 P53 Homo sapiens 32-35 16091363-9 2005 More importantly, small interfering RNA knockdown of ASPP2/(53BP2L) levels attenuated bortezomib-induced apoptosis, and this effect was greater in wild-type p53 cells. Bortezomib 86-96 P53 Homo sapiens 157-160 16204064-7 2005 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. pifithrin 38-53 P53 Homo sapiens 13-16 16204064-7 2005 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. pifithrin 38-53 P53 Homo sapiens 104-107 16204068-3 2005 In contrast, irinotecan (CPT-11) and tomudex sensitized p53 WT, mutant, and null cells to Fas-mediated cell death. ammonium ferrous sulfate 90-93 P53 Homo sapiens 56-59 16051302-7 2005 A proteasome inhibitor, lactacystin, enhances TNFalpha cytotoxicity in p53-positive and -negative cells, suggesting that accumulation of cellular proteins other than p53 might also regulate the cellular response to TNFalpha signaling. lactacystin 24-35 P53 Homo sapiens 71-74 15879012-4 2005 In this study, we report a 23 year old patient with recurrent HCC who was treated with the p53 gene (Gendicine) combining TACE, which resulted in a good clinical prognosis. Chlorotrianisene 122-126 P53 Homo sapiens 91-94 16005638-6 2005 Moreover, gp120 neurotoxicity is markedly reduced by the p53-inhibitor, pifithrin-alpha. pifithrin 72-87 P53 Homo sapiens 57-60 15800902-1 2005 Pifithrin-alpha (PFTalpha) is a small molecule inhibitor of p53. pifithrin 0-15 P53 Homo sapiens 60-63 15800902-1 2005 Pifithrin-alpha (PFTalpha) is a small molecule inhibitor of p53. pifithrin 17-25 P53 Homo sapiens 60-63 15800902-5 2005 We observed that exposure of U87MG cells to PFTalpha before cytotoxic chemotherapy attenuated p53-mediated induction of p21WAF1 protein levels, sensitizing U87MG cells to BCNU and TMZ. pifithrin 44-52 P53 Homo sapiens 94-97 15800902-7 2005 Our findings suggest that in addition to protecting normal cells from the toxic effects of radiation and chemotherapy, small molecule inhibitors of p53, like PFTalpha, might play a role in clinical oncology by sensitizing certain resistant cancers to cytotoxic chemotherapies. pifithrin 158-166 P53 Homo sapiens 148-151 16123139-7 2005 These retinoids were partially dependent on p53 and transforming growth factor beta to exert their radiosensitizing effects. Retinoids 6-15 P53 Homo sapiens 44-47 16123139-9 2005 Taken together, these data suggest that sensitization of the mammary epithelium to p53-dependent apoptosis is a common pathway, which is engaged by retinoids as well as ovarian hormones. Retinoids 148-157 P53 Homo sapiens 83-86 16009942-7 2005 The UVB-induced lesions detected by terminal transferase-PCR were almost exclusively mapped to pyrimidine-rich sequences; however, the UVA1-induced lesions were mapped to purine- and pyrimidine-containing sequences along the p53 gene. purine 171-177 P53 Homo sapiens 225-228 16002925-9 2005 The p53 and phospho-p53 proteins were significantly increased in LCW samples (56,536.8 +/- 4,629 densitometry units [DU] and 58,244.8 +/- 7,492 DU, respectively [+/- SD]), in comparison with the other groups. du 117-119 P53 Homo sapiens 4-7 16002925-9 2005 The p53 and phospho-p53 proteins were significantly increased in LCW samples (56,536.8 +/- 4,629 densitometry units [DU] and 58,244.8 +/- 7,492 DU, respectively [+/- SD]), in comparison with the other groups. du 117-119 P53 Homo sapiens 20-23 16002925-9 2005 The p53 and phospho-p53 proteins were significantly increased in LCW samples (56,536.8 +/- 4,629 densitometry units [DU] and 58,244.8 +/- 7,492 DU, respectively [+/- SD]), in comparison with the other groups. du 144-146 P53 Homo sapiens 4-7 16002925-9 2005 The p53 and phospho-p53 proteins were significantly increased in LCW samples (56,536.8 +/- 4,629 densitometry units [DU] and 58,244.8 +/- 7,492 DU, respectively [+/- SD]), in comparison with the other groups. du 144-146 P53 Homo sapiens 20-23 15905035-5 2005 Treatment with CoQs having shorter isoprenoid chains, especially CoQ2, induced apoptosis in p53-point mutated BALL-1 cells, whereas treatment with longer isoprenoid chains did not. coqs 15-19 P53 Homo sapiens 92-95 15605368-3 2005 Benzyl isothiocyanate (BITC) treatment down-regulates cyclins and CDKs and up-regulates the expression of the CDK inhibitor p21, but up-regulation of p27 or p53 was not detected. benzyl isothiocyanate 23-27 P53 Homo sapiens 157-160 15965099-8 2005 In conclusion, these data suggest that thallium acetate inhibits cell cycle progression at G2/M phase by suppressing CDK activity through the p53-mediated induction of the CDK inhibitor p21(Cip1). thallium acetate 39-55 P53 Homo sapiens 142-145 15916722-2 2005 Our present works show that the expression of E6/E7 oncogenes of human papillomavirus in HeLa cells is inhibited in the presence of anti-tumor reagent tripchlorolide (TC), which results in the up-regulation of p53 in HeLa cells. tripchlorolide 151-165 P53 Homo sapiens 210-213 15916722-2 2005 Our present works show that the expression of E6/E7 oncogenes of human papillomavirus in HeLa cells is inhibited in the presence of anti-tumor reagent tripchlorolide (TC), which results in the up-regulation of p53 in HeLa cells. tripchlorolide 167-169 P53 Homo sapiens 210-213 15916722-3 2005 Interestingly, under the same TC-treatment, the cells at the early S-phase are more susceptible to apoptosis than those at the middle S-phase although p53 protein is stabilized to the same level in both situations. tripchlorolide 30-32 P53 Homo sapiens 151-154 15916722-5 2005 Further analysis demonstrates that anti-apoptotic gene survivin is up-regulated by p53 in the TC-treated middle-S cells, whereas it is down-regulated by p53 in the TC-treated early-S cells. tripchlorolide 94-96 P53 Homo sapiens 83-86 15916722-5 2005 Further analysis demonstrates that anti-apoptotic gene survivin is up-regulated by p53 in the TC-treated middle-S cells, whereas it is down-regulated by p53 in the TC-treated early-S cells. tripchlorolide 164-166 P53 Homo sapiens 153-156 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. Quercetin 43-52 P53 Homo sapiens 123-126 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. Quercetin 43-52 P53 Homo sapiens 254-257 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. Flavonoids 159-169 P53 Homo sapiens 123-126 15795422-6 2005 Micromolar (-)epigallocatechin gallate and quercetin partially eliminated the dichlorodihydrofluorescein (DCF) and phospho-p53 staining, suggesting that these flavonoids inhibited the accumulation of intracellular oxidants and nuclear transactivation of p53 in H2O2-exposed cells. Flavonoids 159-169 P53 Homo sapiens 254-257 15748635-4 2005 Since 5"-CG sequences are methylated along the p53 coding sequence in human cells, these mutations may be derived from sunlight-induced pyrimidine dimers forming at sequences that contain 5-methylcytosine. 5-Methylcytosine 188-204 P53 Homo sapiens 47-50 15755327-0 2005 Activation of p53, inhibition of telomerase activity and induction of estrogen receptor beta are associated with the anti-growth effects of combination of ovarian hormones and retinoids in immortalized human mammary epithelial cells. Retinoids 176-185 P53 Homo sapiens 14-17 15755327-7 2005 In addition, our results showed that both E/P and retinoid treatments resulted in increased RARE and p53 gene activity. Retinoids 50-58 P53 Homo sapiens 101-104 15755327-8 2005 We further demonstrated that p53 and p21 protein expression were induced following the E/P and retinoid treatments. Retinoids 95-103 P53 Homo sapiens 29-32 15701509-1 2005 It is well known that CpG dinucleotide steps in DNA, which are highly methylated at the 5-position of cytosine (meC) in human tissues, exhibit a disproportionate number of mutations within certain codons of the p53 gene. Cytosine 102-110 P53 Homo sapiens 211-214 15735102-0 2005 Ellagic acid potentiates the effect of quercetin on p21waf1/cip1, p53, and MAP-kinases without affecting intracellular generation of reactive oxygen species in vitro. Quercetin 39-48 P53 Homo sapiens 66-69 15735102-4 2005 We found that quercetin and combinations of quercetin and ellagic acid nonsynergistically increased p53 protein levels. Quercetin 14-23 P53 Homo sapiens 100-103 15735102-4 2005 We found that quercetin and combinations of quercetin and ellagic acid nonsynergistically increased p53 protein levels. Quercetin 44-53 P53 Homo sapiens 100-103 15735102-10 2005 In summary, quercetin and ellagic acid combined increase the activation of p53 and p21(cip1/waf1) and the MAP kinases, JNK1,2 and p38, in a more than additive manner, suggesting a mechanism by which quercetin and ellagic acid synergistically induce apoptosis in cancer cells. Quercetin 12-21 P53 Homo sapiens 75-78 15564291-2 2005 Previous studies of lung tumors from both non-smoking women and smoking men in this region showed high frequencies of mutations, consisting mostly of G-->T transversions in the p53 tumor suppressor gene and K-ras oncogene, suggesting that these mutations were caused primarily by polycyclic aromatic hydrocarbons. Polycyclic Aromatic Hydrocarbons 283-315 P53 Homo sapiens 180-183 15474986-0 2005 p53 protein activates the transcription of human proliferating cell nuclear antigen in response to 4-nitroquinoline N-oxide treatment. n-oxide 116-123 P53 Homo sapiens 0-3 15547111-0 2005 5-Aza-cytidine is a potent inhibitor of DNA methyltransferase 3a and induces apoptosis in HCT-116 colon cancer cells via Gadd45- and p53-dependent mechanisms. Azacitidine 0-14 P53 Homo sapiens 133-136 15547111-4 2005 In this study, we investigated the p53 dependence of apoptotic, cell cycle, and growth inhibitory effects of 5-aza-CR, as well as the influence on the expression level of DNMT1, DNMT3a, and DNMT3b in the colon cancer cell line HCT-116. Azacitidine 109-117 P53 Homo sapiens 35-38 15547111-5 2005 Exposure to 5-aza-CR induced the up-regulation of genes promoting cell cycle arrest and DNA repair (p21(WAF1) and GADD45) or apoptosis (p53, RIPK2, Bak1, caspase 5, and caspase 6). Azacitidine 12-20 P53 Homo sapiens 136-139 15547111-7 2005 Co-incubation with pifithrin-alpha (PFT-alpha), a selective p53 inhibitor, restored GADD45, Bcl2, cyclin B1, and p21(WAF1) expression levels and almost completely reversed the growth inhibitory, cell cycle, and apoptotic effects of 5-aza-CR. pifithrin 19-28 P53 Homo sapiens 60-63 15680394-0 2005 Altered trafficking of Fas and subsequent resistance to Fas-mediated apoptosis occurs by a wild-type p53 independent mechanism in esophageal adenocarcinoma. ammonium ferrous sulfate 23-26 P53 Homo sapiens 101-104 15680394-0 2005 Altered trafficking of Fas and subsequent resistance to Fas-mediated apoptosis occurs by a wild-type p53 independent mechanism in esophageal adenocarcinoma. ammonium ferrous sulfate 56-59 P53 Homo sapiens 101-104 15680394-9 2005 CONCLUSIONS: These data suggest that decreased cell-surface expression of Fas and resistance to Fas-mediated apoptosis may occur independently of loss of wt p53 expression. ammonium ferrous sulfate 74-77 P53 Homo sapiens 157-160 15548639-9 2005 Pifithrin-alpha, a synthetic inhibitor of p53 activity, abolished both S-phase arrest and apoptosis induced by genotoxic PAHs, and it potentiated the proliferative effect of BaP. pifithrin 0-15 P53 Homo sapiens 42-45 15830705-0 2005 Intracellular inhibitory effects of Velcade correlate with morphoproteomic expression of phosphorylated-nuclear factor-kappaB and p53 in breast cancer cell lines. Bortezomib 36-43 P53 Homo sapiens 130-133 15830705-1 2005 Velcade, a proteasome inhibitor, has been shown to inhibit DNA binding activity of nuclear factor-kappaB (NF-kappaB) and to stabilize p53 in vitro. Bortezomib 0-7 P53 Homo sapiens 134-137 15830705-9 2005 Velcade treatment resulted in cleaved caspase-3 expression in MDA-231 cells and in the overexpression of p53 and p21WAF1 in all 3 cell lines, as evaluated using Western blotting. Bortezomib 0-7 P53 Homo sapiens 105-108 15830705-10 2005 In summary, morphoproteomic analysis of p-NF-kappaB and p53 can be correlated with the inhibitory effect of Velcade in vitro. Bortezomib 108-115 P53 Homo sapiens 56-59 15642166-15 2005 CONCLUSIONS: The AZ-1-induced cell death of BC-M1 cells mediating the apoptosis pathway might be associated with p53 protein expression, and AZ-1 could have the chance to be a candidate drug for anti-breast cancer following more experimental evidence, such as animal models. 2-aziridin-1-yl-3-((2-((2-(3-aziridin-1-yl-1,4-dioxo-1,4-dihydronaphthalen-2-yl)thio)ethoxy)ethyl)thio)naphthoquinone 17-21 P53 Homo sapiens 113-116 15657359-2 2005 After roscovitine treatment, the level of wild-type p53 protein strongly increased and p53 was accumulated in the nucleus. Roscovitine 6-17 P53 Homo sapiens 52-55 15657359-2 2005 After roscovitine treatment, the level of wild-type p53 protein strongly increased and p53 was accumulated in the nucleus. Roscovitine 6-17 P53 Homo sapiens 87-90 15657359-3 2005 Here, we raised the question of which pathway would be involved in roscovitine-induced apoptosis in MCF-7 cells, which are known to be caspase-3-deficient, and whether roscovitine-mediated activation of p53 protein might positively affect the execution of cell death. Roscovitine 168-179 P53 Homo sapiens 203-206 15657359-5 2005 Interestingly, roscovitine stimulated a site-specific phosphorylation of wild-type p53 protein in a time-dependent manner. Roscovitine 15-26 P53 Homo sapiens 83-86 15657359-9 2005 We compared the kinetics of roscovitine-mediated p53 activation between caspase-3-deficient parental MCF-7 cells and cells reconstituted with caspase-3. Roscovitine 28-39 P53 Homo sapiens 49-52 15589979-0 2005 The monofunctional alkylating agent N-methyl-N"-nitro-N-nitrosoguanidine triggers apoptosis through p53-dependent and -independent pathways. Methylnitronitrosoguanidine 36-72 P53 Homo sapiens 100-103 15589979-5 2005 The S(N)1 DNA alkylating agent N-methyl-N"-nitro-N-nitrosoguanidine (MNNG) triggers apoptosis and the upregulation/phosphorylation of p53; however, the mechanism(s) governing MNNG-induced cell death remain unresolved. Methylnitronitrosoguanidine 31-67 P53 Homo sapiens 134-137 15592306-6 2004 The apoptotic index was reduced by >/=30% ( P <.001), and the expression of p53 was 2-fold lower ( P <.02) in troglitazone-exposed cells under hypoxia for </=16 hours but not different after >24 hours of low oxygen. Troglitazone 119-131 P53 Homo sapiens 82-85 15547693-8 2004 DNA sequencing in FaDu cells showed a G/T point mutation at codon 248 in exon 7 of p53 gene, resulting in an arginine-to-leucine substitution. Leucine 121-128 P53 Homo sapiens 83-86 15450935-0 2004 Influence of p53 and caspase 3 activity on cell death and senescence in response to methotrexate in the breast tumor cell. Methotrexate 84-96 P53 Homo sapiens 13-16 15450935-2 2004 In p53 wild-type, but caspase 3 deficient MCF-7 breast tumor cells, death of approximately 40% of the cell population was observed immediately after acute exposure to 10 microM methotrexate (the IC80 value for a 2 h drug exposure). Methotrexate 177-189 P53 Homo sapiens 3-6 15450935-5 2004 The response to methotrexate in MCF-7/E6 cells with attenuated p53 function was also primarily growth arrest--but lacking characteristics of senescence. Methotrexate 16-28 P53 Homo sapiens 63-66 15450935-7 2004 DNA fragmentation indicative of apoptosis was also detected after exposure to methotrexate in p53 mutant MDA-MB231 breast tumor cells which also express caspase 3. Methotrexate 78-90 P53 Homo sapiens 94-97 15450935-8 2004 Methotrexate-induced both p53 and p21waf1/cip1 in MCF-7 cells within 6 h; however, no significant DNA strand breakage was evident before 18 h, suggesting that the induction of p53 reflects a response to cellular stress other than DNA damage, such as nucleotide depletion. Methotrexate 0-12 P53 Homo sapiens 26-29 15450935-8 2004 Methotrexate-induced both p53 and p21waf1/cip1 in MCF-7 cells within 6 h; however, no significant DNA strand breakage was evident before 18 h, suggesting that the induction of p53 reflects a response to cellular stress other than DNA damage, such as nucleotide depletion. Methotrexate 0-12 P53 Homo sapiens 176-179 15450935-9 2004 Overall, these studies suggest that the nature of the cellular response to methotrexate depends, in large part, on p53 and caspase function. Methotrexate 75-87 P53 Homo sapiens 115-118 15450935-10 2004 p53 appears to be required for methotrexate-induced senescence, but not apoptosis, caspase 3 is required for DNA fragmentation and the morphological changes associated with apoptosis, while neither p53 nor caspase 3 are required for methotrexate-induced growth arrest. Methotrexate 31-43 P53 Homo sapiens 0-3 15450935-10 2004 p53 appears to be required for methotrexate-induced senescence, but not apoptosis, caspase 3 is required for DNA fragmentation and the morphological changes associated with apoptosis, while neither p53 nor caspase 3 are required for methotrexate-induced growth arrest. Methotrexate 233-245 P53 Homo sapiens 0-3 15510008-0 2004 Enhancement of Ad-p53 therapy with docetaxel in head and neck cancer. Docetaxel 35-44 P53 Homo sapiens 18-21 15510008-1 2004 OBJECTIVE: The objective of this project was to determine the mechanisms in which docetaxel enhances Ad-p53 tumor suppressive effects in head and neck cancer. Docetaxel 82-91 P53 Homo sapiens 104-107 15510008-11 2004 Pretreatment with docetaxel enhanced Ad-p53-induced apoptosis through increased expression of exogenous p53. Docetaxel 18-27 P53 Homo sapiens 40-43 15510008-11 2004 Pretreatment with docetaxel enhanced Ad-p53-induced apoptosis through increased expression of exogenous p53. Docetaxel 18-27 P53 Homo sapiens 104-107 15510008-12 2004 Together, the combination of docetaxel and Ad-p53 altered expression of key regulators in the cell cycle, apoptosis and signal transduction pathways with an increase in the expression of p53, bax, cleaved PARP, cleaved caspase-3 and phosphorylation of c-Jun at position at Ser. Docetaxel 29-38 P53 Homo sapiens 187-190 15510008-14 2004 When comparing the docetaxel-resistant to sensitive cell lines, the altered expression of p27 and skp1 by docetaxel and Ad-p53 were dissimilar between these cell lines. Docetaxel 19-28 P53 Homo sapiens 123-126 15510008-15 2004 CONCLUSIONS: Docetaxel enhanced Ad-p53 transduction and increased expression of exogenous p53 gene transfer, apoptosis, and antitumor mechanisms. Docetaxel 13-22 P53 Homo sapiens 35-38 15510008-15 2004 CONCLUSIONS: Docetaxel enhanced Ad-p53 transduction and increased expression of exogenous p53 gene transfer, apoptosis, and antitumor mechanisms. Docetaxel 13-22 P53 Homo sapiens 90-93 15542774-9 2004 The stilbene promoted p53-dependent apoptosis, whereas EGF opposed induction of apoptosis by resveratrol via a PKC-alpha-mediated mechanism. Stilbenes 4-12 P53 Homo sapiens 22-25 15720807-3 2004 In this study, we found that exposure of human lung cancer cell lines A549 (p53-wt) and H1299 (p53-depleted) to 8-Cl-Ado induced cell arrest in the G2/M phase, which was accompanied by accumulation of binucleated and polymorphonucleated cells resulting from aberrant mitosis and failed cytokinesis. 8-chloroadenosine 112-120 P53 Homo sapiens 76-79 15720807-3 2004 In this study, we found that exposure of human lung cancer cell lines A549 (p53-wt) and H1299 (p53-depleted) to 8-Cl-Ado induced cell arrest in the G2/M phase, which was accompanied by accumulation of binucleated and polymorphonucleated cells resulting from aberrant mitosis and failed cytokinesis. 8-chloroadenosine 112-120 P53 Homo sapiens 95-98 15450401-2 2004 By removing alkyl groups from the O6-position in guanine, MGMT can prevent G:C to A:T transition mutations, a type of variation frequently involving TP53 mutations in brain tumors. Guanine 49-56 P53 Homo sapiens 149-153 15450419-0 2004 A mixture of isothiocyanates induces cyclin B1- and p53-mediated cell-cycle arrest and apoptosis of human T lymphoblastoid cells. Isothiocyanates 13-28 P53 Homo sapiens 52-55 15464472-13 2004 Combined gemcitabine and bortezomib enhanced p21 and p53 expression and induced S-phase and G2/M cell-cycle arrests, respectively. Bortezomib 25-35 P53 Homo sapiens 53-56 15466201-5 2004 Sensitization to IR-induced apoptosis by caffeine or UCN-01 was abrogated neither by cycloheximide nor by pifithrin-alpha, an inhibitor of the transcriptional activity of p53. 7-hydroxystaurosporine 53-59 P53 Homo sapiens 171-174 15724841-1 2004 We previously reported (Cancer Chemother Pharmacol 45: 252-258, 2000) that UCN-01 (7-hydroxystaurosporine), a protein kinase inhibitor, which is under clinical trials as an anti-cancer agent in the USA and Japan, enhanced camptothecin-induced cytotoxicity in breast cancer cells that lack p53 function. 7-hydroxystaurosporine 75-81 P53 Homo sapiens 289-292 15724841-1 2004 We previously reported (Cancer Chemother Pharmacol 45: 252-258, 2000) that UCN-01 (7-hydroxystaurosporine), a protein kinase inhibitor, which is under clinical trials as an anti-cancer agent in the USA and Japan, enhanced camptothecin-induced cytotoxicity in breast cancer cells that lack p53 function. 7-hydroxystaurosporine 83-105 P53 Homo sapiens 289-292 15724841-9 2004 Detailed cell-cycle analyses revealed that UCN-01 abrogated S-phase accumulation induced by topotecan treatment in p53 defective MDA231 tumor cells and HMEC/E6 cells. 7-hydroxystaurosporine 43-49 P53 Homo sapiens 115-118 15724841-12 2004 These data indicate that UCN-01 selectively enhances topotecan cytotoxicity in p53 defective cells through the induction of apoptotic signaling pathway(s), although the time course for the induction of cell death is not the same. 7-hydroxystaurosporine 25-31 P53 Homo sapiens 79-82 16200870-6 2004 There was a significant correlation between p53 mutation with simultaneous expression of Pgp and MRP1 and drug-resistance to either vinorelbine or carboplatin. Vinorelbine 132-143 P53 Homo sapiens 44-47 15374966-0 2004 Retinoic acid increases the expression of p53 and proapoptotic caspases and sensitizes keratinocytes to apoptosis: a possible explanation for tumor preventive action of retinoids.

Roscovitine 0-11 P53 Homo sapiens 46-49 11423970-7 2001 Ectopic expression of MDM2 can abrogate the ability of roscovitine to induce p53 stabilization. Roscovitine 55-66 P53 Homo sapiens 77-80 11423970-8 2001 Low concentrations of roscovitine cooperate with the DNA-damaging agent camptothecin to activate p53 in a synergistic fashion. Roscovitine 22-33 P53 Homo sapiens 97-100 11345135-4 2001 Flow cytometric analysis demonstrated that all pancreatic cancer cell lines studied responded with cell surface CD95R and CD95L upregulation to bleomycin treatment, and PANC1 (mt p53) cells demonstrated a dose-dependent response to interferon gamma and bleomycin treatment with CD95R and CD95L up-regulation. Bleomycin 144-153 P53 Homo sapiens 179-182 21044462-9 2001 The different biological effect between 172Leu and 172His shows that some p53 variants such as 172 Arg->Leu may act as wild-type p53. Leucine 43-46 P53 Homo sapiens 74-77 21044462-9 2001 The different biological effect between 172Leu and 172His shows that some p53 variants such as 172 Arg->Leu may act as wild-type p53. Leucine 43-46 P53 Homo sapiens 132-135 11150309-0 2001 Opposite effect of NF-kappa B and c-Jun N-terminal kinase on p53-independent GADD45 induction by arsenite. Arsenic Trioxide 97-105 P53 Homo sapiens 61-64 11150309-2 2001 Using cells derived from human bronchial epithelial cells, we demonstrate that NF-kappaB and c-Jun N-terminal kinase (JNK) reciprocally regulate arsenic trioxide (arsenite)-induced, p53-independent expression of GADD45 protein, a cell cycle checkpoint protein that arrests cells at the G(2)/M phase transition. Arsenic Trioxide 145-161 P53 Homo sapiens 182-185 11150309-2 2001 Using cells derived from human bronchial epithelial cells, we demonstrate that NF-kappaB and c-Jun N-terminal kinase (JNK) reciprocally regulate arsenic trioxide (arsenite)-induced, p53-independent expression of GADD45 protein, a cell cycle checkpoint protein that arrests cells at the G(2)/M phase transition. Arsenic Trioxide 163-171 P53 Homo sapiens 182-185 11306489-3 2001 In this study, we demonstrate that the proteasome inhibitor PS-341 directly inhibits proliferation and induces apoptosis of human MM cell lines and freshly isolated patient MM cells; inhibits mitogen-activated protein kinase growth signaling in MM cells; induces apoptosis despite induction of p21 and p27 in both p53 wild-type and p53 mutant MM cells; overcomes drug resistance; adds to the anti-MM activity of dexamethasone; and overcomes the resistance to apoptosis in MM cells conferred by interleukin-6. Bortezomib 60-66 P53 Homo sapiens 314-317 11306489-3 2001 In this study, we demonstrate that the proteasome inhibitor PS-341 directly inhibits proliferation and induces apoptosis of human MM cell lines and freshly isolated patient MM cells; inhibits mitogen-activated protein kinase growth signaling in MM cells; induces apoptosis despite induction of p21 and p27 in both p53 wild-type and p53 mutant MM cells; overcomes drug resistance; adds to the anti-MM activity of dexamethasone; and overcomes the resistance to apoptosis in MM cells conferred by interleukin-6. Bortezomib 60-66 P53 Homo sapiens 332-335 11277927-7 2001 The results demonstrate that p53 exhibits mispair excision with a specificity of A:A > A:G > A:C opposite the template adenine residue and with a specificity of G:A > G:G > G:T opposite the template guanine residue. Adenine 125-132 P53 Homo sapiens 29-32 11277927-7 2001 The results demonstrate that p53 exhibits mispair excision with a specificity of A:A > A:G > A:C opposite the template adenine residue and with a specificity of G:A > G:G > G:T opposite the template guanine residue. Guanine 211-218 P53 Homo sapiens 29-32 11325644-8 2001 RESULTS: TA was detected in 93% of HG-NHL and tended to be higher in p53+ lymphomas. Tantalum 9-11 P53 Homo sapiens 69-72 11238174-4 2001 Previous studies have indicated that there is a good correlation between G-->T transversion hotspots in lung cancers and sites of preferential formation of polycyclic aromatic hydrocarbon (PAH) adducts along the p53 gene. Polycyclic Aromatic Hydrocarbons 159-190 P53 Homo sapiens 215-218 11238174-4 2001 Previous studies have indicated that there is a good correlation between G-->T transversion hotspots in lung cancers and sites of preferential formation of polycyclic aromatic hydrocarbon (PAH) adducts along the p53 gene. Polycyclic Aromatic Hydrocarbons 192-195 P53 Homo sapiens 215-218 11096068-0 2001 The plant isoflavenoid genistein activates p53 and Chk2 in an ATM-dependent manner. isoflavenoid 10-22 P53 Homo sapiens 43-46 11158615-6 2001 This reduction was prevented by the proteasome inhibitors MG132 and lactacystin, suggesting enhanced p53 degradation in the presence of dicoumarol. lactacystin 68-79 P53 Homo sapiens 101-104 11148027-5 2001 Here, we show by multidimensional NMR spectroscopy that chalcones (1,3-diphenyl-2-propen-1-ones) are MDM2 inhibitors that bind to a subsite of the p53 binding cleft of human MDM2. Chalcones 56-65 P53 Homo sapiens 147-150 11162500-4 2001 However, in an in vitro transcription assay with partially purified basal transcription factors, p53 only partially activated transcription from the same binding site and required PAb421 for full activation. pab421 180-186 P53 Homo sapiens 97-100 11205907-9 2001 By contrast with camptothecin, these lesions persisted for several hours after drug removal and were not formed at 4 degrees C. Et743 treatment induced transient p53 elevation, dose-dependent cell cycle accumulation in G2-M and in G1- and S-phase, and inhibition of DNA synthesis. Trabectedin 128-133 P53 Homo sapiens 162-165 11107118-4 2000 RESULTS: Loss of p53 function (p53-LOF), defined as a failure to induce p21 and/or MDM2 in response to melphalan, was seen in 1/8 drug-sensitive and 6/10 drug-resistant cell lines. Melphalan 103-112 P53 Homo sapiens 17-20 11107118-4 2000 RESULTS: Loss of p53 function (p53-LOF), defined as a failure to induce p21 and/or MDM2 in response to melphalan, was seen in 1/8 drug-sensitive and 6/10 drug-resistant cell lines. Melphalan 103-112 P53 Homo sapiens 31-34 11071927-4 2000 We show that upon treatment of HepG2 cells with 5-fluorouracil or methotrexate, p53 levels increase while concentrations of cyclin B2 mRNA, measured by RT-PCR with the LightCycler system, are reduced. Methotrexate 66-78 P53 Homo sapiens 80-83 11029509-7 2000 Tumor B18 exhibited two novel mutations in the p53 gene, ATGright curved arrow GTG (Metright curved arrow Val) at codon 237 and AATright curved arrow GAT (Asnright curved arrow Asp) at codon 263. Aspartic Acid 177-180 P53 Homo sapiens 47-50 11034086-10 2000 Like other antimicrotubule agents, the sulfamoylated estrone derivatives induced BCL-2 and BCL-XL phosphorylation and increased p53 expression. Estrone 53-60 P53 Homo sapiens 128-131 10994962-3 2000 PCR products of the proline [5"-x(G17)-x(C38)x-3"] and arginine variants [(5"-x(Gl7)-x(G38)x-3"] of the p53 gene are distinguished by an SNP (cytosine or guanine) and were discriminated using both quadrupole and quadrupole ion trap MS analysis. Cytosine 142-150 P53 Homo sapiens 104-107 10994962-3 2000 PCR products of the proline [5"-x(G17)-x(C38)x-3"] and arginine variants [(5"-x(Gl7)-x(G38)x-3"] of the p53 gene are distinguished by an SNP (cytosine or guanine) and were discriminated using both quadrupole and quadrupole ion trap MS analysis. Guanine 154-161 P53 Homo sapiens 104-107 11798837-2 2000 METHODS: Human lung adenocarcinoma cell line GLC-82 was transfected with adenovirus-mediated p53 gene (Ad-p53) combining with administration of either kind of chemotherapeutic agents-cisplatin (CDDP) and arsenic trioxide (As(2)O(3)). Arsenic Trioxide 204-220 P53 Homo sapiens 93-96 10951576-4 2000 The mechanism of ionizing radiation-dependent activation of p53-dependent transcription using DRB is more likely due to inhibition of gene transcription rather than prolonged DNA damage, as the non-genotoxic and general transcription inhibitor Roscovitine also synergistically activates p53 function in ionizing irradiated cells. Roscovitine 244-255 P53 Homo sapiens 60-63 10951576-4 2000 The mechanism of ionizing radiation-dependent activation of p53-dependent transcription using DRB is more likely due to inhibition of gene transcription rather than prolonged DNA damage, as the non-genotoxic and general transcription inhibitor Roscovitine also synergistically activates p53 function in ionizing irradiated cells. Roscovitine 244-255 P53 Homo sapiens 287-290 10945628-3 2000 Whereas p53 can contribute to the nucleoside-induced killing of CLL cells, recent work from this laboratory and elsewhere has shown that such killing can also occur by p53-independent mechanisms. Nucleosides 34-44 P53 Homo sapiens 8-11 10713094-4 2000 Serine 15 of p53 is phosphorylated in vivo in response to ionizing radiation, and antibodies to ATM immunoprecipitate a protein kinase activity that, in the presence of manganese, phosphorylates p53 at serine 15. Manganese 169-178 P53 Homo sapiens 13-16 10713094-4 2000 Serine 15 of p53 is phosphorylated in vivo in response to ionizing radiation, and antibodies to ATM immunoprecipitate a protein kinase activity that, in the presence of manganese, phosphorylates p53 at serine 15. Manganese 169-178 P53 Homo sapiens 195-198 10699891-11 2000 The mutation pattern of p53 with a nearly equal rate of incidence of transitions and transversions and a high rate of incidence of mutations at CpG sites may reflect endogenous mechanisms (e.g., deamination of 5-methylcytosine) rather than exogenous carcinogens. 5-Methylcytosine 210-226 P53 Homo sapiens 24-27 10663644-1 2000 PURPOSE: To determine the ability of UCN-01 to abrogate the cell cycle arrest induced by camptothecin (CPT) in tumor cells that lack p53 function, and therefore enhance the cytotoxicity of CPT in these cells in relation to normal cells with wild-type p53. 7-hydroxystaurosporine 37-43 P53 Homo sapiens 251-254 10663644-14 2000 Our findings suggest potential usefulness of combining UCN-01 in topoisomerase I inhibitor-based drug therapy for the treatment of breast cancer with a dysfunctional p53 gene. 7-hydroxystaurosporine 55-61 P53 Homo sapiens 166-169 22607421-11 2000 p53 with diamide was irreversible and was not reverted by an excess of DTT. Diamide 9-16 P53 Homo sapiens 0-3 10618704-2 1999 Several forms of DNA damage have been shown to activate p53, including those generated by ionising radiation (IR), radio-mimetic drugs, ultraviolet light (UV) and chemicals such as methyl methane sulfonate (MMS). Methyl Methanesulfonate 181-205 P53 Homo sapiens 56-59 10618704-2 1999 Several forms of DNA damage have been shown to activate p53, including those generated by ionising radiation (IR), radio-mimetic drugs, ultraviolet light (UV) and chemicals such as methyl methane sulfonate (MMS). Methyl Methanesulfonate 207-210 P53 Homo sapiens 56-59 10545114-6 1999 Nevertheless, p53-induced apoptosis is still caspase dependent because it could be abolished by z-VAD-fmk. benzyloxycarbonylvalyl-alanyl-aspartyl fluoromethyl ketone 96-105 P53 Homo sapiens 14-17 10531375-4 1999 Cadmium at 10-30 microM impairs the p53 induction in response to DNA-damaging agents such as actinomycin D, methylmethane sulfonate, and hydrogen peroxide. Methyl Methanesulfonate 108-131 P53 Homo sapiens 36-39 10535931-3 1999 Furthermore, treatment of human cells with the S(N)1 DNA methylators N-methyl-N-nitrosourea or N-methyl-N"-nitro-N-nitrosoguanidine results in p53 phosphorylation on serine residues 15 and 392, and these phosphorylation events depend on the presence of functional hMutSalpha and hMutLalpha. Methylnitronitrosoguanidine 95-131 P53 Homo sapiens 143-146 10421649-6 1999 In Fas-positive HCC cases (n = 15), the intrahepatic metastatic foci was less (P =.037), apoptosis of tumor cells was more (P =.004), the disease-free survival rate was higher (P =.004), and p53-positive cases were less (P =.003), compared with Fas-negative cases. ammonium ferrous sulfate 3-6 P53 Homo sapiens 191-194 10360831-1 1999 Lonidamine (LND), a selective inhibitor of the energy metabolism of tumor cells, induces apoptosis, independently of the p53 gene, in the adriamycin(ADR)-resistant MCF7 breast-cancer cell line (MCF7 ADR). lonidamine 0-10 P53 Homo sapiens 121-124 10380883-3 1999 Using immunoblotting with the antibody DO-1, we show that the bands obtained correspond to ethidium-stained DNA, suggesting that each band of the ladder contains a DNA-p53 complex. Ethidium 91-99 P53 Homo sapiens 168-171 10389864-14 1999 We have also shown that Fas levels are significantly increased in response to irradiation in a wt p53 line. ammonium ferrous sulfate 24-27 P53 Homo sapiens 98-101 10408853-8 1999 The mean in vitro bleomycin-induced breaks per cell (a marker of cancer susceptibility) was significantly higher (0.92) for patients who overexpressed p53 in lung tumour tissue than that for patients with no detectable p53 expression in lung tumour tissue (0.65). Bleomycin 18-27 P53 Homo sapiens 151-154 10408853-8 1999 The mean in vitro bleomycin-induced breaks per cell (a marker of cancer susceptibility) was significantly higher (0.92) for patients who overexpressed p53 in lung tumour tissue than that for patients with no detectable p53 expression in lung tumour tissue (0.65). Bleomycin 18-27 P53 Homo sapiens 219-222 10080943-3 1999 Here, we report that although Fas induction is closely linked to the expression of wild type p53, it is not correlated with JNK activation induced by apoptotic stimuli. ammonium ferrous sulfate 30-33 P53 Homo sapiens 93-96 10087941-9 1999 Homozygous deletion in p16INK4A/p15INK4B genes and a codon 259 missense point mutation (GAC-->TAC; Asp-->Tyr) in the TP53 gene were observed in one human papilloma positive scrotal carcinoma case. Aspartic Acid 102-105 P53 Homo sapiens 123-127 11812373-2 1999 METHODS: The p16, p21 and p53 genes mediated by Stearylamine/DOPE (SA liposome) were introduced alone and jointly into the non-small cell lung cancer (NSCLC) cell line A549 and small cell lung cancer (SCLC) SH77. dioleoyl phosphatidylethanolamine 61-65 P53 Homo sapiens 26-29 9989601-1 1999 The proteasome inhibitors lactacystin and AcLLNal induced p53-independent apoptosis in two human glioma cell lines, and the apoptosis was accompanied by up-regulation of immunoreactive wild-type p53, p21Waf1, Mdm2, and p27Kip1. lactacystin 26-37 P53 Homo sapiens 58-61 9989601-1 1999 The proteasome inhibitors lactacystin and AcLLNal induced p53-independent apoptosis in two human glioma cell lines, and the apoptosis was accompanied by up-regulation of immunoreactive wild-type p53, p21Waf1, Mdm2, and p27Kip1. lactacystin 26-37 P53 Homo sapiens 195-198 10369188-2 1999 The accumulation of hsp72 and p53 was observed in A-172 cells cocultivated with heat-shocked T98G cells, which was suppressed by the addition of aminoguanidine to the medium. pimagedine 145-159 P53 Homo sapiens 30-33 9823951-0 1998 Sensitivity to Fas-mediated apoptosis in pediatric acute lymphoblastic leukemia is associated with a mutant p53 phenotype and absence of Bcl-2 expression. ammonium ferrous sulfate 15-18 P53 Homo sapiens 108-111 9823951-3 1998 We therefore investigated the relationship between sensitivity to Fas-mediated apoptosis and (1) Fas expression, (2) p53 status, and (3) Bcl-2 protein levels in pediatric ALL cell lines and primary leukemic cells. ammonium ferrous sulfate 66-69 P53 Homo sapiens 117-120 9823951-13 1998 Sensitivity to Fas-mediated apoptosis was associated with a mt-p53 phenotype and absence of Bcl-2 expression. ammonium ferrous sulfate 15-18 P53 Homo sapiens 63-66 9875298-0 1998 Ketoconazole-induced apoptosis through P53-dependent pathway in human colorectal and hepatocellular carcinoma cell lines. Ketoconazole 0-12 P53 Homo sapiens 39-42 9766444-6 1998 The differentiation response to transfected p53 with or without INF-gamma was inhibited by cyclic adenosine monophosphate (cAMP)-inducing agents (dibutyryl cyclic adenosine 3":5"-monophosphate, forskolin, and 3-isobutyl-1-methylxanthine) in a dose-dependent manner. Colforsin 194-203 P53 Homo sapiens 44-47 9690517-0 1998 Role of p53 in aziridinylbenzoquinone-induced p21waf1 expression. diaziquone 15-37 P53 Homo sapiens 8-11 9647183-9 1998 Transfection with p53 had only a minor effect on the plating efficiency of nonirradiated U87MG cells, reducing the plating efficiency from 0.23 +/- 0.01 in DMEM to 0.22 +/- 0.04 after addition of Ad5CMV-p53. dmem 156-160 P53 Homo sapiens 18-21 9647183-20 1998 Infection of U87MG cells with Ad5CMV-p53 only resulted in an increase in p21 compared with DMEM- and dl312-treated cells. dmem 91-95 P53 Homo sapiens 37-40 9681674-9 1998 Immunohistochemical overexpression of p53 was detected in the basal layer of the cultures treated with methotrexate. Methotrexate 103-115 P53 Homo sapiens 38-41 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. 2,5-dimethyl-3,6-diaziridinyl-1,4-benzoquinone 89-113 P53 Homo sapiens 131-134 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. 2,5-dimethyl-3,6-diaziridinyl-1,4-benzoquinone 115-120 P53 Homo sapiens 131-134 9548807-7 1998 Wild type p53 induction by AZQ was suppressed when DT-diaphorase activity was inhibited by pretreating the cells with dicumarol. diaziquone 27-30 P53 Homo sapiens 10-13 9548807-9 1998 Inhibition of ROS production by the antioxidant enzyme catalase reduced AZQ- and DZQ-mediated p53 induction by about 45%. diaziquone 72-75 P53 Homo sapiens 94-97 9548807-9 1998 Inhibition of ROS production by the antioxidant enzyme catalase reduced AZQ- and DZQ-mediated p53 induction by about 45%. pycnogenols 81-84 P53 Homo sapiens 94-97 9548807-12 1998 On the basis of these data, we propose that the bioreductive activation of AZQ is a prerequisite for p53 induction. diaziquone 75-78 P53 Homo sapiens 101-104 9548807-13 1998 Moreover, the induction of p53 by AZQ requires both the quinone and the aziridine moieties of the AZQ molecule. diaziquone 34-37 P53 Homo sapiens 27-30 9548807-13 1998 Moreover, the induction of p53 by AZQ requires both the quinone and the aziridine moieties of the AZQ molecule. diaziquone 98-101 P53 Homo sapiens 27-30 9548807-14 1998 Although AZQ and its analogues increased p53 levels in MCF-7 cells, p53 induction in these cells may not be responsible for the apoptosis seen upon treatment of MCF-7 cells with these agents. diaziquone 9-12 P53 Homo sapiens 41-44 9579370-8 1998 The known tumor suppressor genes retinoblastoma (RB) and p53 showed loss of expression in GMTT compared with NBT. Nitroblue Tetrazolium 109-112 P53 Homo sapiens 57-60 15281315-8 1998 With new technology for cytological screening techniques using dot ELISA and evidence of differences in TP53 mutations that support the involvement of nitrous oxide, it is clear that there is more to learn from study of this tumour type that may be of general interest in understanding the clonal development of cancer. Nitrous Oxide 151-164 P53 Homo sapiens 104-108 9718082-8 1998 An increase in the level of immunophenotypic expression of wild type p53 was also noted after treatment with all trans retinoic acid and 9-cis retinoic acid. 2-octenal 113-118 P53 Homo sapiens 69-72 9718082-8 1998 An increase in the level of immunophenotypic expression of wild type p53 was also noted after treatment with all trans retinoic acid and 9-cis retinoic acid. Alitretinoin 137-156 P53 Homo sapiens 69-72 9718082-10 1998 In addition, they may be inducing a p53 dependent cell cycle arrest and thus suggests that all-trans and 9-cis retinoic acid may have a cytostatic effect rather than a cytotoxic effect on CaSki cells. Alitretinoin 105-124 P53 Homo sapiens 36-39 9718082-11 1998 The increased expression of p53 positive cells and the inhibition of E6/E7 transcription after treatment with these retinoids may indicate the potential role of all trans and 9-cis retinoic acid as a cell cycle regulator and an antiviral chemoprevention agent. Retinoids 116-125 P53 Homo sapiens 28-31 9395460-1 1997 We previously demonstrated that the anticancer agent and protein kinase C (PKC) inhibitor 7-hydroxystaurosporine (UCN-01) induces apoptosis independently of p53 and protein synthesis in HL60 cells. 7-hydroxystaurosporine 90-112 P53 Homo sapiens 157-160 9395460-1 1997 We previously demonstrated that the anticancer agent and protein kinase C (PKC) inhibitor 7-hydroxystaurosporine (UCN-01) induces apoptosis independently of p53 and protein synthesis in HL60 cells. 7-hydroxystaurosporine 114-120 P53 Homo sapiens 157-160 9388195-2 1997 In this study we treated the HCT-116 colon cancer cell line with alkylating agents including N-methyl-N"-nitro-N-nitrosoguanidine (MNNG),which is known to cause colon cancer in animals, and examined the expression of both APC and p53 genes. Methylnitronitrosoguanidine 131-135 P53 Homo sapiens 230-233 9494534-8 1997 Levels of p53 mRNA decreased with increasing resistance to vindesine, etoposide and fotemustine. fotemustine 84-95 P53 Homo sapiens 10-13 9367071-6 1997 The most common p53 mutations in these tumors were guanine to adenine (G-->A) transitions (10 of 20 tumors; 50%). Guanine 51-58 P53 Homo sapiens 16-19 9367071-6 1997 The most common p53 mutations in these tumors were guanine to adenine (G-->A) transitions (10 of 20 tumors; 50%). Adenine 62-69 P53 Homo sapiens 16-19 9815601-11 1997 p53 wild-type cells seem to be more sensitive to the cytotoxic effects of the combination of UCN-01 + CDDP than the p53 mutant cells. 7-hydroxystaurosporine 93-99 P53 Homo sapiens 0-3 9271379-7 1997 In contrast, exposure to the alkylating agent methyl methanesulfonate results in similar increases of p53 and p21(WAF1/CIP1) mRNA in both cell types. Methyl Methanesulfonate 46-69 P53 Homo sapiens 102-105 9266938-0 1997 Alterations of p53 and Rb genes in a novel human GM-CSF-dependent myeloid cell line (OHN-GM) established from therapy-related leukaemia. ohn-gm 85-91 P53 Homo sapiens 15-18 9595771-4 1997 The reaction with DNA occurs with guanines in the codon 249 of tumor suppressor gene p53. Guanine 34-42 P53 Homo sapiens 85-88 9199206-5 1997 We show for the first time that transcriptional activation of the p53 tumor suppressor gene, as assessed by a reporter plasmid construct, can be down-regulated by cytosine methylation in the basal promoter region. Cytosine 163-171 P53 Homo sapiens 66-69 9135020-5 1997 Using Western blot analysis, we found abundant expression of p53 in the cytoplasm of two Fas-resistant cell lines, DU145 and ND1, and did not find p53 in two Fas-sensitive cell lines, PC3 and ALVA31. ammonium ferrous sulfate 89-92 P53 Homo sapiens 61-64 9139842-4 1997 The results showed that 2% of ACs, 4% of ATL patients and 6% of HAM/TSP patients had anti-p53 antibody. Aminocaproic Acid 30-33 P53 Homo sapiens 90-93 9105409-13 1997 Finally, western analysis revealed that a 24-hr exposure to 5000 IU/mL rIFN-alpha 2a (+/-20 microM AZT) significantly reduced wild-type p53 expression compared with AZT-exposed cells. Zidovudine 99-102 P53 Homo sapiens 136-139 9105409-14 1997 We conclude that rIFN-alpha 2a enhances AZT-induced tumor cell growth inhibition by (i) increasing AZT metabolism, and (ii) inhibiting DNA repair and p53-mediated cell cycle control processes. Zidovudine 40-43 P53 Homo sapiens 150-153 9029132-2 1997 To identify proteins present in complexes with Src family kinases, we subjected p58(c-fgr) or p53/56(lyn) immunoprecipitates from Triton X-100 lysates of PMN incubated on fibrinogen-coated surfaces to in vitro kinase assays.

Bleomycin 66-75 P53 Homo sapiens 133-136 9022073-3 1997 At concentrations present in the sera of patients during therapy, bleomycin induced transient accumulation of nuclear wild-type (wt) p53 and upregulated expression of cell surface CD95 (APO-1/Fas) receptor in hepatoma cells carrying wt p53 (HepG2). Bleomycin 66-75 P53 Homo sapiens 236-239 9137531-1 1997 PURPOSE: Recently, it has been shown that geldanamycin (GA), a benzoquinone ansamycin, is able to deplete mutant p53, p185erbB2 and Raf-1 proteins in cancer cells. benzoquinone ansamycin 63-85 P53 Homo sapiens 113-116 8895764-3 1996 In this report, we describe the mechanism by which the retinoid 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid (CD437) induces p21WAF1/CIP1 in breast carcinoma cells possessing either a wild-type (MCF-7 cells) or mutated (MDA-MB-468 cells) p53. Retinoids 55-63 P53 Homo sapiens 259-262 8878553-2 1996 We found that the proteasome-specific inhibitor lactacystin (LC) induced expression of the cell cycle inhibitor p21WAF1/CIP1 in human cancer cells regardless of their p53 status. lactacystin 48-59 P53 Homo sapiens 167-170 8892753-3 1996 In contrast, the gadd gene stress response to base-damaging agents, such as methylmethane sulfonate (MMS) or UV radiation, or medium depletion (starvation) occurs in all mammalian cells examined to date regardless of p53 status for both GADD45 and also GADD153, which is not IR-responsive in many lines with functional p53. Methyl Methanesulfonate 101-104 P53 Homo sapiens 319-322 8692233-11 1996 We found a weak association between total PAH-DNA adduct levels in lung tissue and TP53 mutations. Polycyclic Aromatic Hydrocarbons 42-45 P53 Homo sapiens 83-87 8676917-0 1996 p53 accumulates in micronuclei after treatment with a DNA breaking chemical, methylnitrosourea, and with the spindle poison, vinblastine. Vinblastine 125-136 P53 Homo sapiens 0-3 8676920-7 1996 The induction pattern of the three p53 effector genes by the alkylating agent methylmethane sulfonate (MMS) was also attenuated in WI-L2-NS cells. Methyl Methanesulfonate 78-101 P53 Homo sapiens 35-38 8676920-7 1996 The induction pattern of the three p53 effector genes by the alkylating agent methylmethane sulfonate (MMS) was also attenuated in WI-L2-NS cells. Methyl Methanesulfonate 103-106 P53 Homo sapiens 35-38 8649776-2 1996 By using recombination PCR in vitro mutagenesis, we introduced point mutations into the codon 273 of wild-type (wt) p53 (pC53-SN3) from Arg to His (pC53-273H [273H]), Asp (273D), Pro (273P), Lys (273K), Leu (273L) or Thr (273T), and compared their biological and biochemical activities with wt p53 and cancer-derived 175H, 248W and 273H/309S. Aspartic Acid 167-170 P53 Homo sapiens 116-119 8649776-2 1996 By using recombination PCR in vitro mutagenesis, we introduced point mutations into the codon 273 of wild-type (wt) p53 (pC53-SN3) from Arg to His (pC53-273H [273H]), Asp (273D), Pro (273P), Lys (273K), Leu (273L) or Thr (273T), and compared their biological and biochemical activities with wt p53 and cancer-derived 175H, 248W and 273H/309S. Leucine 203-206 P53 Homo sapiens 116-119 8603385-0 1996 Effects of sodium saccharin and linoleic acid on mRNA levels of Her2/neu and p53 in a human breast epithelial cell line. Saccharin 11-27 P53 Homo sapiens 77-80 8603385-1 1996 The effects of two food-related chemicals (sodium saccharin and linoleic acid) on the levels of Her2/neu and p53 mRNA in a non-cancerous human breast epithelial cell line (HBL-100) were tested in comparison with the effects of the known tumor promoter phorbol 12-myristate 13-acetate (TPA). Saccharin 43-59 P53 Homo sapiens 109-112 8814703-6 1996 The wild-type TP53+ cells were morphologically flat and enlarged when cultured in vitro, and were less able to form colonies in soft agar. Agar 133-137 P53 Homo sapiens 14-18 8603737-1 1996 Evidence that p58C-FGR and p53/56LYN redistributed to a Triton X-100-insoluble cytoskeletal fraction, also enriched in the caveolar protein caveolin, display an enhanced kinase activity. Octoxynol 56-68 P53 Homo sapiens 27-30 8603737-4 1996 Moreover, we found that up to about 20% of p58c-fgr and p53/56lyn redistribute to a Triton X-100-insoluble fraction after PMA stimulation, and it is this fraction of the two kinases which diplays an increased activity. Octoxynol 84-96 P53 Homo sapiens 56-59 8944328-3 1996 TP53 mutations were identified in four out of 30 (13%) DCIS by constant denaturant gel electrophoresis (CDGE). cdge 104-108 P53 Homo sapiens 0-4 8521385-0 1995 Microtubule-active drugs taxol, vinblastine, and nocodazole increase the levels of transcriptionally active p53. Vinblastine 32-43 P53 Homo sapiens 108-111 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes. Vinblastine 67-78 P53 Homo sapiens 108-111 8521385-2 1995 We examined the ability of three microtubule-active agents, taxol, vinblastine, and nocodazole, to increase p53 levels and activate p53-dependent processes.

N-methyl-N-benzylnitrosamine 218-223 P53 Homo sapiens 91-94 7784087-2 1995 It has recently been shown (Lin et al., 1994b) that the transcriptional activator domain of the p53 protein contains two amino acids, leu-22 and trp-23, which are required by the wild-type p53 protein for transcriptional activity. Leucine 134-137 P53 Homo sapiens 96-99 7784087-2 1995 It has recently been shown (Lin et al., 1994b) that the transcriptional activator domain of the p53 protein contains two amino acids, leu-22 and trp-23, which are required by the wild-type p53 protein for transcriptional activity. Leucine 134-137 P53 Homo sapiens 189-192 7663341-0 1995 Backbone dynamics of the oligomerization domain of p53 determined from 15N NMR relaxation measurements. 15n 71-74 P53 Homo sapiens 51-54 7663341-1 1995 The backbone dynamics of the tetrameric p53 oligomerization domain (residues 319-360) have been investigated by two-dimensional inverse detected heteronuclear 1H-15N NMR spectroscopy at 500 and 600 MHz. 15n 162-165 P53 Homo sapiens 40-43 7537340-5 1995 Finally, we employed all three libraries to reveal the distinct mechanisms by which PAb421 and PAb122, two monoclonal antibodies that allosterically activate sequence-specific DNA binding by p53, react specifically with the same positively-charged C-terminal segment. pab421 84-90 P53 Homo sapiens 191-194 7882284-4 1995 Specimens containing p53 mutations tended to exhibit an increased growth delay in procarbazine-treated xenografts and lower amounts of AT. Procarbazine 82-94 P53 Homo sapiens 21-24 7882284-5 1995 CONCLUSIONS: p53 mutations in brain tumors may contribute to procarbazine sensitivity by failing to induce arrest at the G1/S cell-cycle checkpoint, thereby preventing the repair of procarbazine-induced genetic alterations. Procarbazine 61-73 P53 Homo sapiens 13-16 7882284-5 1995 CONCLUSIONS: p53 mutations in brain tumors may contribute to procarbazine sensitivity by failing to induce arrest at the G1/S cell-cycle checkpoint, thereby preventing the repair of procarbazine-induced genetic alterations. Procarbazine 182-194 P53 Homo sapiens 13-16 7727133-2 1995 A nuclear phosphoprotein, p53, was isolated by immunoprecipitation after biosynthetic labeling with 35S, 32P or 33P in cultured human cells. Phosphorus-33 112-115 P53 Homo sapiens 26-29 7727133-7 1995 The relative phosphorylation of each p53 isoform was estimated by normalizing 33P or 32P isoform volumes with the corresponding 35S volume and showed progressive phosphorylation of acidic isoforms. Phosphorus-33 78-81 P53 Homo sapiens 37-40 7955057-3 1994 Only one case of hydatidiform mole was found to have a missense point mutation (codon 295, CCT-->CTT, i.e. proline to leucine) of the p53 gene. Leucine 121-128 P53 Homo sapiens 137-140 8275462-1 1994 The ability of cloned human O6-methylguanine-DNA methyltransferase to repair a methylated guanine in a CpG-containing sequence, i.e., island, was studied by using a synthetic double-stranded 20-mer oligonucleotide from codon 248 of the p53 gene and another designed sequence. Guanine 37-44 P53 Homo sapiens 236-239 8275462-6 1994 These results suggest that O6-methylation of the guanine moiety at CpG islands may not be efficiently repaired when normal 5mC is present and this may contribute significantly to an increase in mutagenesis of p53 and like molecules. Guanine 49-56 P53 Homo sapiens 209-212 8275462-6 1994 These results suggest that O6-methylation of the guanine moiety at CpG islands may not be efficiently repaired when normal 5mC is present and this may contribute significantly to an increase in mutagenesis of p53 and like molecules. 5-Methylcytosine 123-126 P53 Homo sapiens 209-212 8517643-5 1993 Immunoreactive p53 was observed in the nuclei of the cancer cells in 15/33 (45%) by pAbDO-7, 11/26 (42%) by pAb1801, and 16/33 (48%) by pAbCM-1. pabdo-7 84-91 P53 Homo sapiens 15-18 8380918-11 1993 Less frequent than the deamination of 5-methyl cytosine in CpG dinucleotides, mutations resulting in loss or gain of nucleotide base pairs may represent the second highest endogenous mutagenic event for p53 gene in human cancers. 5-Methylcytosine 38-55 P53 Homo sapiens 203-206 1895390-9 1991 That p53 was stabilized because of association with LPV T antigen and not because of mutation was demonstrated with the p53 conformation-dependent monoclonal antibody PAb246. pab246 167-173 P53 Homo sapiens 5-8 1895390-9 1991 That p53 was stabilized because of association with LPV T antigen and not because of mutation was demonstrated with the p53 conformation-dependent monoclonal antibody PAb246. pab246 167-173 P53 Homo sapiens 120-123 1895390-11 1991 Sequential immunoprecipitation showed all detectable p53 to be of the PAb246+ class in each LPV-transformed cell line, suggesting that the stable p53 was indeed wild type. pab246 70-76 P53 Homo sapiens 53-56 1924299-3 1991 We have developed a modification of denaturing gradient gel electrophoresis termed "constant denaturant gel electrophoresis" (CDGE), which provides a rapid and sensitive method to screen the four conserved regions within the p53 gene where the majority of p53 mutations have been reported. cdge 126-130 P53 Homo sapiens 225-228 1924299-3 1991 We have developed a modification of denaturing gradient gel electrophoresis termed "constant denaturant gel electrophoresis" (CDGE), which provides a rapid and sensitive method to screen the four conserved regions within the p53 gene where the majority of p53 mutations have been reported. cdge 126-130 P53 Homo sapiens 256-259 1924299-10 1991 We conclude that CDGE is a rapid and effective technique to screen for p53 mutations. cdge 17-21 P53 Homo sapiens 71-74 1707233-7 1991 The improved morphologic resolution available in periodate lysine paraformaldehyde dichromate (PLPD)-fixed, paraffin-embedded tissue permitted several conclusions to be made: p53 is confined to neoplastic nuclei; staining in positive tumors is heterogeneous and often more marked at the infiltrative margins; and staining intensity is dramatically reduced in mitotic cells. plpd 95-99 P53 Homo sapiens 175-178 1986144-4 1991 On Northern, Southern, and Western blot analysis, the p53 gene and its product appear to be normal in DU-145. du 102-104 P53 Homo sapiens 54-57 2259385-8 1990 This mutation leads to substitution of aspartic acid for glycine in one of the regions identified as a frequent target of point mutations in p53. Aspartic Acid 39-52 P53 Homo sapiens 141-144 2141685-6 1990 Phosphoamino acid analysis of in vitro phosphorylated p53 revealed a phosphorylation predominantly on serine residues similar to p53 phosphorylated in vivo. Phosphoamino Acids 0-17 P53 Homo sapiens 54-57 1691710-6 1990 A series of different p53 mutants all react more strongly with PAb240 than with PAb246. pab246 80-86 P53 Homo sapiens 22-25 2139577-4 1990 For example, activated mutant p53 fails to react with PAb246 (p53-246 degrees). pab246 54-60 P53 Homo sapiens 30-33 33803928-6 2021 Proteome-based mechanistic analysis revealed that inhibition of ganglioside synthesis downregulated the expression of AURKA, AURKB, TTK, and NDC80 involved in the regulation of kinetochore metaphase signaling, which is essential for chromosome segregation and mitotic progression and probably under the control of activation of TP53-dependent cell cycle arrest. Gangliosides 64-75 P53 Homo sapiens 328-332 11931974-9 2002 Addition of pifithrin-alpha (PFT), a specific inhibitor of p53, reduced the activation of p53 with a concomitant decrease in growth arrest at S phase. pifithrin 12-27 P53 Homo sapiens 59-62 11931974-9 2002 Addition of pifithrin-alpha (PFT), a specific inhibitor of p53, reduced the activation of p53 with a concomitant decrease in growth arrest at S phase. pifithrin 12-27 P53 Homo sapiens 90-93 34947951-7 2021 Puromycin screening revealed that 75.0% (21/28) and 68.7% (22/32) of cell colonies contained a P53 mutation at sgRNA-Exon5 and sgRNA-Exon4, respectively.

Sodium Glutamate 36-39 P53 Homo sapiens 106-110 34880920-15 2021 In the arsenic trioxide-target-pathway-HCC network, targets such as AKT1, RAF1, RELA, TP53, and PTEN had a higher degree. Arsenic Trioxide 7-23 P53 Homo sapiens 86-90 34785649-5 2021 However, recent data suggests that STRA6 may not function merely as a retinoid transporter but also act as a complex signalling hub in its own right, being able to affect cell fate through the integration of retinoid signalling with other key pathways, such as those involving p53, JAK/STAT, Wnt/beta catenin and calcium. Retinoids 208-216 P53 Homo sapiens 277-280 34343634-9 2021 Moreover, RRP15 depletion in p53-mutant PLC5 and p53-deleted Hep3B cells induced metabolic shift from the glycolytic pentose-phosphate to mitochondrial oxidative phosphorylation via regulating a series of key genes such as HK2 and TIGAR, and thus, promoted the generation of ROS and apoptosis. Pentosephosphates 117-134 P53 Homo sapiens 29-32 34343634-9 2021 Moreover, RRP15 depletion in p53-mutant PLC5 and p53-deleted Hep3B cells induced metabolic shift from the glycolytic pentose-phosphate to mitochondrial oxidative phosphorylation via regulating a series of key genes such as HK2 and TIGAR, and thus, promoted the generation of ROS and apoptosis.

Flavonoids 45-55 P53 Homo sapiens 20-23 34768743-8 2021 Flavonoids inhibit B-cell lymphoma 2 (Bcl-2) via the p53 signaling pathway, which is a significant apoptotic target in many cancer types, hence suppressing a major dysregulated pathway in cancer. Flavonoids 0-10 P53 Homo sapiens 53-56 34768743-9 2021 To date, there have been no studies reported which extensively highlight the role of flavonoids and especially the different classes of flavonoids in the modulation of Bcl-2 in the P53 signaling pathway. Flavonoids 85-95 P53 Homo sapiens 181-184 34768743-9 2021 To date, there have been no studies reported which extensively highlight the role of flavonoids and especially the different classes of flavonoids in the modulation of Bcl-2 in the P53 signaling pathway. Flavonoids 136-146 P53 Homo sapiens 181-184 34768743-10 2021 Herein, we discuss the modulation of Bcl-2 in the p53 signaling pathway by different classes of flavonoids and highlight different mechanisms through which this modulation can occur. Flavonoids 96-106 P53 Homo sapiens 50-53 34644781-9 2021 RESULTS: In our results, 6-shogaol not only suppressed proliferation and anchorage-independent cell growth in OSCC cells, but also induced apoptosis by regulating the apoptosis-associated factors such as p53, Bax, Bcl-2, and cleaved caspase-3. shogaol 25-34 P53 Homo sapiens 204-207 34711017-7 2021 RESULTS: CCH caused concentration and time-dependent reduction in the viability of human HepG2 and MCF7 cells, pre-G1 apoptosis and cell cycle arrest at G2/M stage, significantly higher P53 and TNF-alpha mRNA and protein expression levels but significantly lower COX2 mRNA and protein expression levels. 1-acetyl-2-(coumariniminecarboxamide-3-yl)hydrazine 9-12 P53 Homo sapiens 186-189 34638761-3 2021 Previously, we reported that niclosamide targets a metabolic vulnerability in p53-deficient tumours, providing a basis for patient stratification and personalised treatment strategies. Niclosamide 29-40 P53 Homo sapiens 78-81 34638761-8 2021 Notably, quantitative scoring of drug sensitivity suggests that elimination of its nitro group enhanced the target selectivity of niclosamide against p53 deficiency. Niclosamide 130-141 P53 Homo sapiens 150-153 34577642-9 2021 We conclude that the use of HO-3867 as an adjuvant to conventional therapeutics in ovarian cancers harboring TP53 missense mutations could improve patient outcomes.

EBR 54-57 P53 Homo sapiens 109-112 22138446-6 2012 We show that concurrent treatment with GA and TPT is able to reverse TPT induced up-regulation of the anti-apoptotic protein Bcl2 in both p53+/+ and p53-/- HCT116 cells. tpt 46-49 P53 Homo sapiens 138-141 22138446-6 2012 We show that concurrent treatment with GA and TPT is able to reverse TPT induced up-regulation of the anti-apoptotic protein Bcl2 in both p53+/+ and p53-/- HCT116 cells. tpt 46-49 P53 Homo sapiens 149-152 22138446-6 2012 We show that concurrent treatment with GA and TPT is able to reverse TPT induced up-regulation of the anti-apoptotic protein Bcl2 in both p53+/+ and p53-/- HCT116 cells. tpt 69-72 P53 Homo sapiens 138-141 22138446-6 2012 We show that concurrent treatment with GA and TPT is able to reverse TPT induced up-regulation of the anti-apoptotic protein Bcl2 in both p53+/+ and p53-/- HCT116 cells. tpt 69-72 P53 Homo sapiens 149-152 25214240-5 2014 We showed that EBR induced mitochondria-mediated and caspase-dependent apoptosis in wt and p53 stable transfected PC3 cells, which suggesting that EBR-induced apoptosis regardless of p53 expression. EBR 15-18 P53 Homo sapiens 91-94 25214240-5 2014 We showed that EBR induced mitochondria-mediated and caspase-dependent apoptosis in wt and p53 stable transfected PC3 cells, which suggesting that EBR-induced apoptosis regardless of p53 expression. EBR 147-150 P53 Homo sapiens 91-94 25568812-0 2014 Rapid and Sensitive Detection of p53 Based on DNA-Protein Binding Interactions Using Silver Nanoparticle Films and Microwave Heating. Silver 85-91 P53 Homo sapiens 33-36 22256804-2 2012 METHODS: We performed a molecular analysis to identify oncogenic mutations (HRAS, KRAS, NRAS, CDKN2A, and TP53) in the lesions from patients treated with the BRAF inhibitor vemurafenib. Vemurafenib 173-184 P53 Homo sapiens 106-110 25182801-8 2014 These effects were influenced by the p53 activity: cells carrying an active p53 were more sensitive to the combination of PARP inhibitor and RT, while cells carrying an inactive p53 displayed a higher sensitivity to the combination of PARP inhibitor and TPT. Topotecan 254-257 P53 Homo sapiens 37-40 22715313-9 2012 Here, we have identified three drug-like compounds that are ZINC01019934, ZINC00624418 and ZINC00664532 adequate to interrupt stability of p53-mortalin complex that warrant for anticancer agent. zinc01019934 60-72 P53 Homo sapiens 139-142 25182801-8 2014 These effects were influenced by the p53 activity: cells carrying an active p53 were more sensitive to the combination of PARP inhibitor and RT, while cells carrying an inactive p53 displayed a higher sensitivity to the combination of PARP inhibitor and TPT. Topotecan 254-257 P53 Homo sapiens 76-79 25182801-8 2014 These effects were influenced by the p53 activity: cells carrying an active p53 were more sensitive to the combination of PARP inhibitor and RT, while cells carrying an inactive p53 displayed a higher sensitivity to the combination of PARP inhibitor and TPT. Topotecan 254-257 P53 Homo sapiens 76-79 22719783-8 2012 In addition, 6-gingerol treatment elevated intracellular reactive oxygen species (ROS) and phosphorylation level of p53. gingerol 13-23 P53 Homo sapiens 116-119 25182801-9 2014 Our study suggests that p53 activity influences the differential sensitivity of GBM cells to combined treatments of TPT, RT, and PARP inhibitors. Topotecan 116-119 P53 Homo sapiens 24-27 22719783-9 2012 These findings indicate that exposure of 6-gingerol may induce intracellular ROS and upregulate p53, p27(Kip1), and p21(Cip1) levels leading to consequent decrease of CDK1, cyclin A, and cyclin B1 as result of cell cycle arrest in LoVo cells. gingerol 41-51 P53 Homo sapiens 96-99 25263558-7 2014 Furthermore, Blm-s is a direct target gene of p53 and AP1 via the ataxia telangiectasia mutated (ATM)- and c-Jun N-terminal kinase (JNK)-signaling pathways activated by DSBs. dsbs 169-173 P53 Homo sapiens 46-49 23056207-9 2012 Also, decreased androgen receptor, prostate specific antigen, p53 and p21 protein levels were demonstrated in response to treatment with NU9056. 1,2-bis(isothiazol-5-yl)disulfane 137-143 P53 Homo sapiens 62-65 24454781-10 2014 The increased binding of the H-Ras transcriptional regulator p53 to its consensus sequence within the intronic CpG island further confirmed the effect of EPA as demethylating agent. Eicosapentaenoic Acid 154-157 P53 Homo sapiens 61-64 24711049-0 2014 Nickel accumulation in lung tissues is associated with increased risk of p53 mutation in lung cancer patients. Nickel 0-6 P53 Homo sapiens 73-76 24275138-7 2014 However, combining the latter with 100muM CoCl2 was preferentially toxic for mutant p53 C8161 melanoma, and was enhanced by catalase in wt p53 C8161 cells. cobaltous chloride 42-47 P53 Homo sapiens 84-87 24275138-7 2014 However, combining the latter with 100muM CoCl2 was preferentially toxic for mutant p53 C8161 melanoma, and was enhanced by catalase in wt p53 C8161 cells. cobaltous chloride 42-47 P53 Homo sapiens 139-142 23029106-8 2012 Although the survivin promoter-reporter system was used for the identification of FL118, our studies revealed that FL118 not only inhibits survivin expression but also selectively and independently inhibits three additional cancer-associated survival genes (Mcl-1, XIAP and cIAP2) in a p53 status-independent manner, while showing no inhibitory effects on control genes. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione 115-120 P53 Homo sapiens 286-289 24711049-3 2014 This study assessed whether nickel exposure increased the occurrence of p53 mutations due to DNA repair inhibition by nickel. Nickel 28-34 P53 Homo sapiens 72-75 24772329-4 2014 The p53 activation induced in response to the inhibition of the electron transport chain complex III has been shown to be triggered by the impairment of the de novo pyrimidine biosynthesis due to the suppression of DHODH. pyrimidine 165-175 P53 Homo sapiens 4-7 24711049-3 2014 This study assessed whether nickel exposure increased the occurrence of p53 mutations due to DNA repair inhibition by nickel. Nickel 118-124 P53 Homo sapiens 72-75 23024792-2 2012 In this study, sensitising topotecan to colon cancer cells with different P53 status via modulation of autophagy was examined. Topotecan 27-36 P53 Homo sapiens 74-77 24711049-5 2014 Nickel levels in p53 mutant patients were significantly higher than those in p53 wild-type patients. Nickel 0-6 P53 Homo sapiens 17-20 23024792-3 2012 METHODOLOGY/PRINCIPAL FINDINGS: The DNA damage induced by topotecan treatment resulted in cytoprotective autophagy in colon cancer cells with wild-type p53. Topotecan 58-67 P53 Homo sapiens 152-155 24711049-6 2014 When patients were divided into high- and low-nickel subgroups by median nickel level, the high-nickel subgroup of patients had an odds ratio (OR) of 3.25 for p53 mutation risk relative to the low-nickel subgroup patients. Nickel 46-52 P53 Homo sapiens 159-162 23024792-4 2012 However, in cells with mutant p53 or p53 knockout, treatment with topotecan induced autophagy-associated cell death. Topotecan 66-75 P53 Homo sapiens 30-33 23024792-4 2012 However, in cells with mutant p53 or p53 knockout, treatment with topotecan induced autophagy-associated cell death. Topotecan 66-75 P53 Homo sapiens 37-40 23024792-5 2012 In wild-type p53 colon cancer cells, topotecan treatment activated p53, upregulated the expression of sestrin 2, induced the phosphorylation of the AMPKalpha subunit at Thr172, and inhibited the mTORC1 pathway. Topotecan 37-46 P53 Homo sapiens 13-16 24641404-0 2014 D-pinitol promotes apoptosis in MCF-7 cells via induction of p53 and Bax and inhibition of Bcl-2 and NF-kappaB. pinitol 0-9 P53 Homo sapiens 61-64 24641404-9 2014 The results revealed that D-pinitol significantly inhibited the proliferation of MCF-7 cells in a concentration-dependent manner, while upregulating the expression of p53, Bax and down regulating Bcl-2 and NF-kB. pinitol 26-35 P53 Homo sapiens 167-170 24841718-0 2014 Low ATM protein expression and depletion of p53 correlates with olaparib sensitivity in gastric cancer cell lines. olaparib 64-72 P53 Homo sapiens 44-47 24841718-6 2014 Moreover, reducing ATM kinase activity using a small-molecule inhibitor (KU55933) or shRNA-mediated depletion of ATM protein enhanced olaparib sensitivity in gastric cancer cell lines with depletion or inactivation of p53. olaparib 134-142 P53 Homo sapiens 218-221 23024792-5 2012 In wild-type p53 colon cancer cells, topotecan treatment activated p53, upregulated the expression of sestrin 2, induced the phosphorylation of the AMPKalpha subunit at Thr172, and inhibited the mTORC1 pathway. Topotecan 37-46 P53 Homo sapiens 67-70 23024792-6 2012 Furthermore, the inhibition of autophagy enhanced the anti-tumour effect of topotecan treatment in wild-type p53 colon cancer cells but alleviated the anti-tumour effect of topotecan treatment in p53 knockout cells in vivo. Topotecan 76-85 P53 Homo sapiens 109-112 23024792-6 2012 Furthermore, the inhibition of autophagy enhanced the anti-tumour effect of topotecan treatment in wild-type p53 colon cancer cells but alleviated the anti-tumour effect of topotecan treatment in p53 knockout cells in vivo. Topotecan 173-182 P53 Homo sapiens 196-199 23024792-7 2012 CONCLUSIONS/SIGNIFICANCE: These results imply that the wild-type p53-dependent induction of cytoprotective autophagy is one of the cellular responses that determines the cellular sensitivity to the DNA-damaging drug topotecan. Topotecan 216-225 P53 Homo sapiens 65-68 25147862-7 2014 Interestingly, data also revealed the dysregulation of p53 and FOXO3 was dependent on the regulation of SIRT1 rather than Vit C. Ascorbic Acid 122-127 P53 Homo sapiens 55-58 24711049-6 2014 When patients were divided into high- and low-nickel subgroups by median nickel level, the high-nickel subgroup of patients had an odds ratio (OR) of 3.25 for p53 mutation risk relative to the low-nickel subgroup patients. Nickel 73-79 P53 Homo sapiens 159-162 24711049-6 2014 When patients were divided into high- and low-nickel subgroups by median nickel level, the high-nickel subgroup of patients had an odds ratio (OR) of 3.25 for p53 mutation risk relative to the low-nickel subgroup patients. Nickel 73-79 P53 Homo sapiens 159-162 24711049-6 2014 When patients were divided into high- and low-nickel subgroups by median nickel level, the high-nickel subgroup of patients had an odds ratio (OR) of 3.25 for p53 mutation risk relative to the low-nickel subgroup patients. Nickel 73-79 P53 Homo sapiens 159-162 22916232-0 2012 Modeling of arylamide helix mimetics in the p53 peptide binding site of hDM2 suggests parallel and anti-parallel conformations are both stable. arylamide 12-21 P53 Homo sapiens 44-47 24711049-7 2014 The OR for p53 mutation risk of lifetime non-smokers, particularly females, in the high-nickel subgroup was greater than that in the low-nickel subgroup. Nickel 88-94 P53 Homo sapiens 11-14 22916232-4 2012 Results from both docking and molecular dynamics simulations are consistent with the arylamides binding in the p53 peptide binding pocket. arylamides 85-95 P53 Homo sapiens 111-114 24330704-11 2013 Moreover, eugenol up-regulated the versatile cyclin-dependent kinase inhibitor p21WAF1 protein, and inhibited the proliferation of breast cancer cells in a p53-independent manner. Eugenol 10-17 P53 Homo sapiens 156-159 22916232-5 2012 Simulations of arylamides in the p53 binding pocket of hDM2 are consistent with binding, exhibiting similar structural dynamics in the pocket as simulations of known hDM2 binders Nutlin-2 and a benzodiazepinedione compound. arylamides 15-25 P53 Homo sapiens 33-36 24711049-7 2014 The OR for p53 mutation risk of lifetime non-smokers, particularly females, in the high-nickel subgroup was greater than that in the low-nickel subgroup. Nickel 137-143 P53 Homo sapiens 11-14 22916232-8 2012 In the first, the arylamide compound lies parallel to the observed p53 helix. arylamide 18-27 P53 Homo sapiens 67-70 22916232-9 2012 In the second class, not previously identified or proposed, the arylamide compound lies anti-parallel to the p53 helix. arylamide 64-73 P53 Homo sapiens 109-112 24711049-10 2014 Therefore, increased risk of p53 mutation due to defective DNA repair caused by high nickel levels in lung tissues may be one mechanism by which nickel exposure contributes to lung cancer development, especially in lifetime female non-smokers. Nickel 85-91 P53 Homo sapiens 29-32 24711049-10 2014 Therefore, increased risk of p53 mutation due to defective DNA repair caused by high nickel levels in lung tissues may be one mechanism by which nickel exposure contributes to lung cancer development, especially in lifetime female non-smokers. Nickel 145-151 P53 Homo sapiens 29-32 24954032-9 2014 Our data indicate interplay between p53, FoxO3a and 14-3-3 leading to an attenuated BaP induced apoptosis in cells co-exposed to TCDD, PCB 153 or estradiol. 2,2',4,4',5,5'-Hexachlorobiphenyl 135-142 P53 Homo sapiens 36-39 21937165-1 2011 Serdemetan (JNJ-26854165) is a novel tryptamine compound with antiproliferative activity in various p53 wild-type (WT) tumor cell lines. JNJ 26854165 0-10 P53 Homo sapiens 100-103 21937165-5 2011 At 2Gy, surviving fractions were 0.72 and 0.97 for p53-WT HCT116 and p53-null cells exposed to 0.5muM of Serdemetan, respectively (p<0.05). JNJ 26854165 105-115 P53 Homo sapiens 51-54 21937165-5 2011 At 2Gy, surviving fractions were 0.72 and 0.97 for p53-WT HCT116 and p53-null cells exposed to 0.5muM of Serdemetan, respectively (p<0.05). JNJ 26854165 105-115 P53 Homo sapiens 69-72 23911866-0 2013 A ruthenium(II) beta-carboline complex induced p53-mediated apoptosis in cancer cells. ruthenium(ii) beta-carboline 2-30 P53 Homo sapiens 47-50 24802382-0 2014 Ciprofloxacin as a potential radio-sensitizer to tumor cells and a radio-protectant for normal cells: differential effects on gamma-H2AX formation, p53 phosphorylation, Bcl-2 production, and cell death. Ciprofloxacin 0-13 P53 Homo sapiens 148-151 24164297-4 2013 Since p53-Delta30 was efficiently labeled, poly(ADP-ribosyl)ation target site(s) of wt-p53 must reside outside its carboxy-terminal-domain. poly(adp-ribosyl) 43-60 P53 Homo sapiens 87-90 24121233-1 2013 A novel series of 3-methyl-1-benzofuran derivatives were synthesized and screened in vitro for their antiproliferative activity against two human NSCLC cell lines (NSCLC-N6 mutant p53 and A549 wild type p53). 3-Methylbenzofuran 18-39 P53 Homo sapiens 180-183 22134241-3 2011 Thus, we hypothesized that inhibition of HRR (mediated by Chk1 via AZD7762) and PARP1 [via olaparib (AZD2281)] would selectively sensitize p53 mutant pancreatic cancer cells to radiation. olaparib 101-108 P53 Homo sapiens 139-142 22134241-6 2011 We found that the combination of AZD7762 and olaparib produced significant radiosensitization in p53 mutant pancreatic cancer cells and in all of the isogenic cancer cell lines. olaparib 45-53 P53 Homo sapiens 97-100 22134241-7 2011 The magnitude of radiosensitization by AZD7762 and olaparib was greater in p53 mutant cells compared with p53 wild type cells. olaparib 51-59 P53 Homo sapiens 75-78 24121233-1 2013 A novel series of 3-methyl-1-benzofuran derivatives were synthesized and screened in vitro for their antiproliferative activity against two human NSCLC cell lines (NSCLC-N6 mutant p53 and A549 wild type p53). 3-Methylbenzofuran 18-39 P53 Homo sapiens 203-206 22134241-7 2011 The magnitude of radiosensitization by AZD7762 and olaparib was greater in p53 mutant cells compared with p53 wild type cells. olaparib 51-59 P53 Homo sapiens 106-109 24802382-8 2014 CIP pretreatment reduced Bcl-2 production but promoted p53 phosphorylation, caspase-3 activation and cell death. Ciprofloxacin 0-3 P53 Homo sapiens 55-58 22101337-3 2011 Using gene expression microarray analysis, we find that DNA damage response (DDR) pathways elicited by veliparib (ABT-888), a PARP inhibitor, plus topotecan comprise the G1/S checkpoint, ATM, and p53 signaling pathways in p53-wildtype cancer cell lines and BRCA1, BRCA2 and ATR pathway in p53-mutant lines. Topotecan 147-156 P53 Homo sapiens 196-199 22101337-3 2011 Using gene expression microarray analysis, we find that DNA damage response (DDR) pathways elicited by veliparib (ABT-888), a PARP inhibitor, plus topotecan comprise the G1/S checkpoint, ATM, and p53 signaling pathways in p53-wildtype cancer cell lines and BRCA1, BRCA2 and ATR pathway in p53-mutant lines. Topotecan 147-156 P53 Homo sapiens 222-225 22101337-3 2011 Using gene expression microarray analysis, we find that DNA damage response (DDR) pathways elicited by veliparib (ABT-888), a PARP inhibitor, plus topotecan comprise the G1/S checkpoint, ATM, and p53 signaling pathways in p53-wildtype cancer cell lines and BRCA1, BRCA2 and ATR pathway in p53-mutant lines. Topotecan 147-156 P53 Homo sapiens 222-225 22101337-4 2011 In contrast, topotecan alone induces the G1/S checkpoint pathway in p53-wildtype lines and not in p53-mutant cells. Topotecan 13-22 P53 Homo sapiens 68-71 22829208-8 2013 Iodine-negative epithelium presented significantly higher immunoreactions for P53 and GLUT 1 in basal, parabasal, and superficial layers, respectively, whereas the reaction for Ki67 in the superficial layer was higher than that in iodine-positive epithelium (Wilcoxon signed-rank test, P < 0.05). Iodine 0-6 P53 Homo sapiens 78-81 24802382-10 2014 In normal healthy human PBMCs, CIP failed to block the radiation-induced gamma-H2AX increase but effectively increased Bcl-2 production, but blocked the phospho-p53 increase and subsequent cell death. Ciprofloxacin 31-34 P53 Homo sapiens 161-164 24040331-1 2013 Serdemetan (JNJ-26854165), an antagonist to Mdm2, was anticipated to promote the activation of p53. JNJ 26854165 0-10 P53 Homo sapiens 95-98 24889088-5 2014 Flow cytometric analysis and DNA fragmentation revealed that germacrone promoted apoptosis of glioma cells, associated with an increased expression of p53 and bax and decreased expression of bcl-2. germacrone 61-71 P53 Homo sapiens 151-154 24040331-1 2013 Serdemetan (JNJ-26854165), an antagonist to Mdm2, was anticipated to promote the activation of p53. JNJ 26854165 12-24 P53 Homo sapiens 95-98 21963806-3 2011 Sappanchalcone-treated oral cancer cells showed an increased cytosolic level of cytochrome c, downregulated Bcl-2 expression, upregulated Bax and p53 expression, caspase-3 and -9 activation, and poly (ADP-ribose) polymerase cleavage. sappanchalcone 0-14 P53 Homo sapiens 146-149 23583370-0 2013 Simvastatin induced HCT116 colorectal cancer cell apoptosis through p38MAPK-p53-survivin signaling cascade. Simvastatin 0-11 P53 Homo sapiens 76-79 25119920-9 2014 Among 20 patients who received fludarabine therapy, the overall remission rate for those with p53 gene deletion (20%) was lower than those without (75%) (P<0.05). fludarabine 31-42 P53 Homo sapiens 94-97 23583370-9 2013 Simvastatin"s actions on p21(cip/Waf1), survivin and apoptosis were reduced in p53 null HCT116 cells. Simvastatin 0-11 P53 Homo sapiens 79-82 23583370-10 2013 Simvastatin caused an increase in p53 phosphorylation and acetylation. Simvastatin 0-11 P53 Homo sapiens 34-37 23583370-11 2013 In addition, simvastatin activated p38 mitogen-activated protein kinase (p38MAPK), whereas an inhibitor of p38MAPK signaling abrogated simvastatin"s effects of increasing p53 and p21(cip/Waf1) promoter luciferase activity. Simvastatin 135-146 P53 Homo sapiens 171-174 23583370-13 2013 Furthermore, Sp1 binding to the survivin promoter region decreased while p53 and p63 binding to the promoter region increased after simvastatin exposure.

Simvastatin 44-55 P53 Homo sapiens 119-122 23938375-11 2013 The association with dMMR in HGEC with ARID1A/PTEN alterations, TP53 wild type expression pattern and unfavorable outcome suggests that different oncogenetic pathways within HGEC are present. dmmr 21-25 P53 Homo sapiens 64-68 21088491-1 2010 Atomistic simulations of a set of stapled peptides derived from the transactivation domain of p53 (designed by Verdine & colleagues, JACS 2007 129:2456) and complexed to MDM2 reveal that the good binders are uniquely characterized by higher helicity and by extensive interactions between the hydrocarbon staples and the MDM2 surface; in contrast the poor binders have reduced helicity and their staples are mostly solvent exposed. Verdine 111-118 P53 Homo sapiens 94-97 23860250-9 2013 We further hypothesize that the higher binding affinity of the novel Geldanamycin analogue for hsp90 alpha triggers the degradation of nonfunctional mutant p53 by cellular proteasomes. geldanamycin 69-81 P53 Homo sapiens 156-159 20727621-3 2010 For instance, the Ru(II)(p-cymene)(isonicotinate)Cl(2) complex 6a of the known 4-(3,4,5-trimethoxyphenyl)-5-(3-hydroxy-4-methoxyphenyl)-oxazole 4a was far more active than the latter against cells of the p53-competent wild-type form of HCT-116 colon carcinoma at low 0.01 muM concentrations. 4-(3,4,5-trimethoxyphenyl)-5-(3-hydroxy-4-methoxyphenyl)-oxazole 79-143 P53 Homo sapiens 204-207 20727621-5 2010 The Ru(arene) complexes 6a-c were also more efficacious against combretastatin-refractory p53(+) cells of human HT-29 colon carcinoma when compared to their parent 4-(3,4-dimethoxy-5-methoxy/halo-phenyl)-5-(3-hydroxy-4-methoxyphenyl)-oxazoles 4a-c. arene 7-12 P53 Homo sapiens 90-93 23495037-4 2013 Blockade of cyclooxygenase-2 (COX-2) activity by siRNA or NS398 correspondingly inhibited ceramide-induced p53 Ser-15 phosphorylation and apoptosis; thus COX-2 appears at the apex of the p38 kinase-mediated signaling cascade induced by ceramide. N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide 58-63 P53 Homo sapiens 107-110 20686355-3 2010 In the latter case, Ets1 molecules bind to palindromic sequences in which two Ets-binding sites (EBS) are separated by four base pairs, for example in the promoters of stromelysin-1 and p53. ethylbenzene 97-100 P53 Homo sapiens 186-189 20493187-8 2010 Treatment with GA and 17-AAG led to growth arrests in G1 and S phases, increased sub-G1 hypodipoid cell population, induced apoptotic cell death, and upregulated P53 and P21 expression, although the drug-induced Bcl-2 upregulation cannot prevent cell death. geldanamycin 15-17 P53 Homo sapiens 162-165 23514434-0 2013 Silver-based nanoparticles induce apoptosis in human colon cancer cells mediated through p53.

Selenious Acid 81-89 P53 Homo sapiens 63-66 23435014-9 2013 Interestingly, TP53 polymorphisms in intron 7 (rs12947788 and rs12951053) were more frequently identified in asbestos-exposed NSCLC (P = 0.046) and MPM patients than in unexposed patients (P < 0.001 and P = 0.012, respectively). Asbestos 109-117 P53 Homo sapiens 15-19 23406775-13 2013 CONCLUSION: Our study established a novel TP53-associated pediatric ACC xenograft and identified topotecan as a potentially effective agent for treating children with this disease.

Formaldehyde 35-43 P53 Homo sapiens 28-31 23117090-6 2013 In the meantime, the up-regulation of p53 and reactive oxygen species increase were observed, which suggested that germacrone might be a new potent chemopreventive drug candidate for liver cancer via regulating the expression of proteins related to G2/M cell cycle and apoptosis, and p53 and oxidative damage may play important roles in the inhibition of human hepatoma cells growth by germacrone. germacrone 115-125 P53 Homo sapiens 38-41 19941079-7 2010 RESULTS: Transcriptional activity of the MDM2 promoter containing the SNP309 GG genotype was significantly lower than that containing the TT genotype in p53-null lung cancer cells cotransfected with wild-type p53 expression plasmid under mithramycin A treatment. mithramycin A 238-251 P53 Homo sapiens 209-212 23117090-6 2013 In the meantime, the up-regulation of p53 and reactive oxygen species increase were observed, which suggested that germacrone might be a new potent chemopreventive drug candidate for liver cancer via regulating the expression of proteins related to G2/M cell cycle and apoptosis, and p53 and oxidative damage may play important roles in the inhibition of human hepatoma cells growth by germacrone. germacrone 115-125 P53 Homo sapiens 284-287 24175842-4 2013 Menadione treatment increased the expression of pro-apoptotic proteins, Bax and p53, with a concurrent decrease in anti-apoptotic proteins, Bcl-2 and p65. Vitamin K 3 0-9 P53 Homo sapiens 80-83 20450732-0 2010 [Vitexicarpin affects proliferation and apoptosis in mutated p53 breast cancer cell]. casticin 1-13 P53 Homo sapiens 61-64 20450732-1 2010 OBJECTIVE: To elucidate the effect of proliferation and apoptosis induced by vitexicarpin in mutated p53 Hs578T cell line and study the expression of c-Myc, p21 and Bcl-2 protein in Hs578T and wild p53 MCF-7 cell pre-treated with vitexicarpin. casticin 77-89 P53 Homo sapiens 101-104 23803025-3 2013 We recently investigated the genetic status of p53 and H-ras, which are known to be frequently mutated in Indian oral carcinomas in GO tissues and found them to only contain wild type sequences, which suggested a non-neoplastic nature of phenytoin induced GO. Phenytoin 238-247 P53 Homo sapiens 47-50 20036271-10 2010 Our results suggest that arsenite"s interference with activation of P53 via poly(ADP-ribosyl)ation may play a role in the comutagenic and cocarcinogenic effects of arsenite. arsenite 164-172 P53 Homo sapiens 68-71 23150440-2 2013 Here, we describe a detailed protocol to identify small molecules capable of targeting p53-MDM2/MDMX interactions using a fluorescence polarization assay with Rhodamine-labeled p53 peptides. Rhodamines 159-168 P53 Homo sapiens 87-90 23150440-2 2013 Here, we describe a detailed protocol to identify small molecules capable of targeting p53-MDM2/MDMX interactions using a fluorescence polarization assay with Rhodamine-labeled p53 peptides.

Lidocaine 24-33 P53 Homo sapiens 267-270 23441616-1 2013 Nobiletin is a typical polymethoxyl flavone from citrus fruits that has anticancer properties, but the molecular mechanism of its inhibitory effects on the growth of p53-mutated SNU-16 human gastric cancer cells has not been explored. nobiletin 0-9 P53 Homo sapiens 166-169 23441616-7 2013 The results of this study suggest the potential application of nobiletin to the enhancement of 5-FU efficiency in p53 mutant tumors. nobiletin 63-72 P53 Homo sapiens 114-117 25198662-4 2013 Selenite induced phosphorylation of p53 at the vital site Ser15 via p38MAPK and ERK. Selenious Acid 0-8 P53 Homo sapiens 36-39 20043868-0 2010 Stabilization and translocation of p53 to mitochondria is linked to Bax translocation to mitochondria in simvastatin-induced apoptosis. Simvastatin 105-116 P53 Homo sapiens 35-38 25198662-8 2013 Furthermore, in p53 mutant U937 leukemia cells, selenite could not elicit such a switch from autophagy to apoptosis, laying emphasis on the crucial role p53 played in this process. Selenious Acid 48-56 P53 Homo sapiens 16-19 23124131-8 2013 RESULTS: CO(2) incubation was associated with an increase in ROS production (p < 0.01), cell DNA damage mainly after 24 h (12 % increase of tail DNA content and 4-fold increase of tail length) and a significant up-regulation in p53 expression at 24 h with an intense nuclear staining. co(2) 9-14 P53 Homo sapiens 231-234 20043868-4 2010 Interestingly, the simvastatin-induced apoptosis was accompanied by p53 stabilization involving Mdm2 degradation. Simvastatin 19-30 P53 Homo sapiens 68-71 20043868-7 2010 Moreover, knockdown or deficiency of p53 expression reduced both Bax translocation to mitochondria and MMP disruption in simvastatin-induced apoptosis. Simvastatin 121-132 P53 Homo sapiens 37-40 20043868-8 2010 Taken together, these all indicate that stabilization and translocation of p53 to mitochondria is involved in Bax translocation to mitochondria in simvastatin-induced apoptosis. Simvastatin 147-158 P53 Homo sapiens 75-78 23124131-10 2013 CONCLUSIONS: In vitro-simulated pneumoperitoneum environment with CO(2) induces oxidative stress and cell DNA damage, leading to p53 up-regulation involved in cell-cycle arrest of neuroblastoma cells. co(2) 66-71 P53 Homo sapiens 129-132 20085733-3 2010 Vitamin C can alleviate cell senescence by p53 repression and may accelerate reprogramming by synergizing with epigenetic regulators.

Formaldehyde 51-59 P53 Homo sapiens 21-25 22944355-4 2012 Based on this rationale, Cenersen, a phosphorothioate oligonucleotide antisense to p53-mRNA was synthesized and tested in clinical trials for patients with acute myeloid leukemia (AML). Phosphorothioate Oligonucleotides 37-69 P53 Homo sapiens 83-86 23205301-4 2012 We also found compensatory increases in cytosolic deoxycytidine kinase (dCK) and thymidine kinase 1 (TK1) and in mitochondrial deoxyguanosine kinase (dGK), all of the salvage dNTP supply system; in contrast, the remaining mitochondrial salvage enzyme thymidine kinase 2 (TK2) decreased with p53 loss. Parathion 175-179 P53 Homo sapiens 291-294 22705848-8 2012 Besides the topoisomerase inhibitor doxorubicin known for its cardiotoxicity, we show that the mitochondria-specific inhibitor menadione is able to activate p53 and to kill effectively myotubes.

Oxidopamine 36-42 P53 Homo sapiens 145-148 22638860-7 2012 Our study highlighted the role of iNOS in the neurodegeneration of nigrostriatal dopaminergic neurons in the 6-OHDA animal model of PD and suggested that the microglial activation-iNOS-p53-Bax-CC3 apoptotic pathway plays a key role in the neurodegeneration in the 6-OHDA model. Oxidopamine 109-115 P53 Homo sapiens 185-188 22892142-0 2012 Enhanced antitumor activity of vitamin C via p53 in cancer cells. Ascorbic Acid 31-40 P53 Homo sapiens 45-48 22638860-7 2012 Our study highlighted the role of iNOS in the neurodegeneration of nigrostriatal dopaminergic neurons in the 6-OHDA animal model of PD and suggested that the microglial activation-iNOS-p53-Bax-CC3 apoptotic pathway plays a key role in the neurodegeneration in the 6-OHDA model. Oxidopamine 264-270 P53 Homo sapiens 185-188 22797300-7 2012 Our identification of HCLK2 as a substrate of PHD3 reveals the mechanism through which hypoxia inhibits the DDR, suggesting hydroxylation of HCLK2 is a potential therapeutic target for regulating the ATR/CHK1/p53 pathway. hclk2 22-27 P53 Homo sapiens 209-212 22892142-4 2012 Because p53 is activated by DNA-damaging stress and then regulates various cellular conditions, we hypothesized that p53 can sensitize cancer cells to ascorbate. Ascorbic Acid 151-160 P53 Homo sapiens 8-11 22892142-4 2012 Because p53 is activated by DNA-damaging stress and then regulates various cellular conditions, we hypothesized that p53 can sensitize cancer cells to ascorbate. Ascorbic Acid 151-160 P53 Homo sapiens 117-120 22892142-5 2012 Using isogenic cancer cells, we observed that the presence of p53 can affect ascorbate cytotoxicity, and also reactivation of p53 can make cancer cells sensitive to ascorbate. Ascorbic Acid 77-86 P53 Homo sapiens 62-65 22149137-0 2012 The Hsp90 inhibitor SNX-7081 synergizes with and restores sensitivity to fludarabine in chronic lymphocytic leukemia cells with lesions in the TP53 pathway: a potential treatment strategy for fludarabine refractory disease. fludarabine 73-84 P53 Homo sapiens 143-147 22892142-5 2012 Using isogenic cancer cells, we observed that the presence of p53 can affect ascorbate cytotoxicity, and also reactivation of p53 can make cancer cells sensitive to ascorbate. Ascorbic Acid 165-174 P53 Homo sapiens 126-129 22149137-0 2012 The Hsp90 inhibitor SNX-7081 synergizes with and restores sensitivity to fludarabine in chronic lymphocytic leukemia cells with lesions in the TP53 pathway: a potential treatment strategy for fludarabine refractory disease. fludarabine 192-203 P53 Homo sapiens 143-147 22149137-4 2012 In seven cell lines and 23 patient samples synergy between SNX-7081 and fludarabine (2-FaraA) was apparent in the three TP53 mutated cell lines and at significantly lower concentrations in TP53 or ATM dysfunctional patient cells. fludarabine 72-83 P53 Homo sapiens 120-124 22892142-6 2012 p53-dependent enhancement of ascorbate cytotoxicity is caused by increased reactive oxygen species generation via a differentially regulated p53 transcriptional network. Ascorbic Acid 29-38 P53 Homo sapiens 0-3 22149137-4 2012 In seven cell lines and 23 patient samples synergy between SNX-7081 and fludarabine (2-FaraA) was apparent in the three TP53 mutated cell lines and at significantly lower concentrations in TP53 or ATM dysfunctional patient cells. fludarabine 85-92 P53 Homo sapiens 120-124 22614867-0 2012 Nano-TiO2-induced apoptosis by oxidative stress-mediated DNA damage and activation of p53 in human embryonic kidney cells. titanium dioxide 5-9 P53 Homo sapiens 86-89 22892142-6 2012 p53-dependent enhancement of ascorbate cytotoxicity is caused by increased reactive oxygen species generation via a differentially regulated p53 transcriptional network. Ascorbic Acid 29-38 P53 Homo sapiens 141-144 22614867-9 2012 In conclusion, ROS-mediated oxidative stress, the activation of p53, Bax, caspase-3 and oxidative DNA damage are involved in the mechanistic pathways of nano-TiO(2)-induced apoptosis in HEK-293 cells. titanium dioxide 158-164 P53 Homo sapiens 64-67 22892142-7 2012 We also found that transcriptionally activated p53 was derived from MDM2 ubiquitination by ascorbate and subsequently its signaling network renders cancer cells more susceptible to oxidative stress. Ascorbic Acid 91-100 P53 Homo sapiens 47-50 22892142-8 2012 Similar to the p53 effect on in vitro ascorbate cytotoxicity, inhibition of tumor growth is also stronger in p53-expressing tumors than in p53-deficient ones in vivo. Ascorbic Acid 38-47 P53 Homo sapiens 15-18 22592527-3 2012 We found that low doses (~0.5 microM) of reversine, which selectively inhibit MPS1 and hence impair the spindle assembly checkpoint, kill human TP53 (-/-) colon carcinoma cells less efficiently than their wild-type counterparts. 2-(4-morpholinoanilino)-6-cyclohexylaminopurine 41-50 P53 Homo sapiens 144-148 22892142-8 2012 Similar to the p53 effect on in vitro ascorbate cytotoxicity, inhibition of tumor growth is also stronger in p53-expressing tumors than in p53-deficient ones in vivo. Ascorbic Acid 38-47 P53 Homo sapiens 109-112 22892142-8 2012 Similar to the p53 effect on in vitro ascorbate cytotoxicity, inhibition of tumor growth is also stronger in p53-expressing tumors than in p53-deficient ones in vivo. Ascorbic Acid 38-47 P53 Homo sapiens 109-112 22416035-2 2012 Here, we show that mantle cell lymphoma (MCL) cells deficient in both ATM and p53 are more sensitive to the PARP inhibitor olaparib than cells lacking ATM function alone. olaparib 123-131 P53 Homo sapiens 78-81 22416035-3 2012 In ATM-deficient MCL cells, olaparib induced DNA-PK-dependent phosphorylation and stabilization of p53 as well as expression of p53-responsive cell cycle checkpoint regulators, and inhibition of DNA-PK reduced the toxicity of olaparib in ATM-deficient MCL cells. olaparib 28-36 P53 Homo sapiens 99-102 22892142-9 2012 This is the first observation that ascorbate cytotoxicity is positively related to p53 expression, activating its transcriptional network to worsen intracellular oxidative stress and consequently enhancing its cytotoxicity. Ascorbic Acid 35-44 P53 Homo sapiens 83-86 22416035-3 2012 In ATM-deficient MCL cells, olaparib induced DNA-PK-dependent phosphorylation and stabilization of p53 as well as expression of p53-responsive cell cycle checkpoint regulators, and inhibition of DNA-PK reduced the toxicity of olaparib in ATM-deficient MCL cells. olaparib 28-36 P53 Homo sapiens 128-131 22416035-4 2012 Thus, both DNA-PK and p53 regulate the response of ATM-deficient MCL cells to olaparib. olaparib 78-86 P53 Homo sapiens 22-25 22892142-10 2012 Based on our study, reactivation of p53 may help to achieve more consistent cytotoxic effects of ascorbate in cancer therapies.

Phenytoin 43-52 P53 Homo sapiens 20-23 23317213-2 2012 However, a detailed analysis for the presence of mutations in p53 and ras genes, which are the two most frequently mutated genes in cancers, in phenytoin induced gingival overgrowth tissues has hitherto not been performed. Phenytoin 144-153 P53 Homo sapiens 62-65 23317213-6 2012 CONCLUSION: Our result indicates that mutational alteration of p53 and H-ras genes is infrequent in phenytoin induced gingival growth, which thus suggests a non malignant nature of this pathology. Phenytoin 100-109 P53 Homo sapiens 63-66 19559674-4 2009 AC-93253 significantly enhanced acetylation of tubulin, p53, and histone H4, confirming SIRT2 and SIRT1 as its cellular targets.

Homo sapiens 58-61 19180570-8 2009 We further show that over-expression of dominant negative p53 or down-expression of endogenous wild-type p53 resulted in up-regulation of Cyr61 expression, suggesting a functional link between Cyr61 and p53 in cancers. cyr61 138-143 P53 Homo sapiens 105-108 22028325-8 2011 Although the overall contribution of miR-194 to neoplastic growth is context dependent, p53-induced activation of this GI tract-specific miRNA during ischemia could promote angiogenesis and facilitate tissue repair. mir-194 37-44 P53 Homo sapiens 88-91 22134241-3 2011 Thus, we hypothesized that inhibition of HRR (mediated by Chk1 via AZD7762) and PARP1 [via olaparib (AZD2281)] would selectively sensitize p53 mutant pancreatic cancer cells to radiation. olaparib 91-99 P53 Homo sapiens 139-142 22009179-4 2011 Importantly, radiation enhancement by BEZ235 coincides with a prominent p53-dependent accelerated senescence phenotype characterized by positive beta-galactosidase

EZN-2208 9-17 P53 Homo sapiens 106-109 18400537-5 2008 In both Molt-4 LXSN leukemia cells exposed to gamma-irradiation and in EB-1 colon cancer cells treated with ZnCl(2), p53 up-regulation led to de novo ceramide synthesis with predominance of N-palmitoylsphingosine (C16-ceramide) synthesis. N-palmitoylsphingosine 190-212 P53 Homo sapiens 117-120 21809836-2 2011 After metabolic activation, some NOCs can induce carboxymethylation of nucleobases through a diazoacetate intermediate, which could give rise to p53 mutations similar to those seen in human gastrointestinal cancers. diazoacetate 93-105 P53 Homo sapiens 145-148 18400537-5 2008 In both Molt-4 LXSN leukemia cells exposed to gamma-irradiation and in EB-1 colon cancer cells treated with ZnCl(2), p53 up-regulation led to de novo ceramide synthesis with predominance of N-palmitoylsphingosine (C16-ceramide) synthesis. N-palmitoylsphingosine 214-226 P53 Homo sapiens 117-120 18358838-2 2008 Here we studied whether p53 mitochondrial translocation and subsequent apoptosis were affected by blocking mitochondrial permeability transition pore using cyclosporine A (CsA) and bongkrekic acid (BA) in skin epidermal JB6 cells and skin tissues. Bongkrekic Acid 181-196 P53 Homo sapiens 24-27 18358838-2 2008 Here we studied whether p53 mitochondrial translocation and subsequent apoptosis were affected by blocking mitochondrial permeability transition pore using cyclosporine A (CsA) and bongkrekic acid (BA) in skin epidermal JB6 cells and skin tissues. Bongkrekic Acid 198-200 P53 Homo sapiens 24-27 20558185-7 2010 While the benzofurylquinazolines increased the expression level of the pro-inflammatory gene IL1-alpha as well as p21 and p53 in the PC3 cell line, a phenylpyrrolocarbazole had the converse effect on p53 expression. phenylpyrrolocarbazole 150-172 P53 Homo sapiens 200-203 21671008-5 2011 alpha-PGG induced apoptosis in RKO cells through p53, Bax and caspase 3. alphaPGG 0-9 P53 Homo sapiens 49-52 20700496-0 2010 Lysine120 interactions with p53 response elements can allosterically direct p53 organization. lysine120 0-9 P53 Homo sapiens 28-31 21067279-5 2011 Both types of TiO2 nanoparticles transiently upregulated mRNA expression of p53 and its downstream regulated DNA damage responsive genes (mdm2, gadd45alpha, p21), providing additional evidence that TiO2 nanoparticles are genotoxic. titanium dioxide 14-18 P53 Homo sapiens 76-79 20700496-0 2010 Lysine120 interactions with p53 response elements can allosterically direct p53 organization. lysine120 0-9 P53 Homo sapiens 76-79 20662736-8 2010 Although mitoxantrone, ellipticine, camptothecin, and topotecan all exhibited concentration-dependent disruption of the p53-hDM2 PPIB, they were much less potent than Nutlin-3. Topotecan 54-63 P53 Homo sapiens 120-123 18358838-3 2008 Our results demonstrated that CsA and BA blocked TPA-induced p53 translocation, leading to protection against the loss of mitochondrial membrane potential and Complex I activity, and eventually suppression of apoptosis.

UNII-37WM0V5E17 0-5 P53 Homo sapiens 178-181 19499188-7 2010 This confirms the therapeutic potential of LA-12 as a more potent cytostatic agent for both tumor cells expressing wild type p53 and for p53-deficient or mutant cells. UNII-37WM0V5E17 43-48 P53 Homo sapiens 125-128 19499188-7 2010 This confirms the therapeutic potential of LA-12 as a more potent cytostatic agent for both tumor cells expressing wild type p53 and for p53-deficient or mutant cells.

Homo sapiens 132-135 20371239-7 2010 Western blot analysis indicated that BTZQ may up-regulate expression of cyclin B, p21, p53 and cytochrome c, but down-regulate cdk1 expression in a dose-dependent manner, leading to apoptosis of BC-M1 cells. btzq 37-41 P53 Homo sapiens 87-90 21458064-4 2011 Such PC-Dox/p53 nanocomplexes ensure that both drug and gene can be delivered to the same cancer cells.

tetrandrine 36-47 P53 Homo sapiens 173-176 18348409-1 2007 OBJECTIVE: To assess the ability of tetrandrine (Tet) to enhance the sensitivity to irradiation and its mechanism in cell lines of human breast cancer p53-mutant MCF-7/ADR, p53-wild-type MCF-7 and human colon carcinoma p53-mutant HT-29 as well as in C26 colorectal carcinoma-bearing BALB/c mice. tetrandrine 49-52 P53 Homo sapiens 173-176 20230799-8 2010 Knockdown of NAG-1 using siRNA significantly reversed LYR-8-induced cell death in both wild-type and mutant p53-expressing colon cancer cells.

OBJECTIVE: To assess the ability of tetrandrine (Tet) to enhance the sensitivity to irradiation and its mechanism in cell lines of human breast cancer p53-mutant MCF-7/ADR, p53-wild-type MCF-7 and human colon carcinoma p53-mutant HT-29 as well as in C26 colorectal carcinoma-bearing BALB/c mice. tetrandrine 49-52 P53 Homo sapiens 173-176 18348409-7 2007 RESULTS: Clonogenic assay showed that tetrandrine markedly enhanced the lethal effect of X-rays on p53-mutant MCF-7/ADR and HT-29 cells and the sensitization enhancement ratio (SER) of tetrandrine was 1.51 and 1.63, but its SER was only

generation, activation of NF-kappaB, p53, c-Jun, protease caspase-3 activation and mitochondria depolarization leading to nuclei fragmentation. Vitamin K 3 26-36 P53 Homo sapiens 212-215 17914575-6 2007 A comparison with the wild-type after 1 nano-second molecular dynamic simulation analysis revealed a significant structural change (over 4A displacement) in the contact loop Lys-Ser-Val which lies upstream and next to the mutated site in the TP53, that sterically prevents its DNA-binding activity. Valine 182-185 P53 Homo sapiens 242-246 20504344-7 2010 After performing messenger RNA expression profile of the same patients, the activation of p53-responsive genes was detected in fludarabine responsive cases only, therefore suggesting a possible mechanism linked to microRNA deregulation in non-responder patients. fludarabine 127-138 P53 Homo sapiens 90-93 20504344-8 2010 Importantly, inhibition of miR-21 and miR-222 by anti-miRNA oligonucleotides induced a significant increase in caspase activity in fludarabine-treated p53-mutant MEG-01 cells, suggesting that miR-21 and miR-222 up-regulation may be involved in the establishment of fludarabine resistance. fludarabine 131-142 P53 Homo sapiens 151-154 20504344-8 2010 Importantly, inhibition of miR-21 and miR-222 by anti-miRNA oligonucleotides induced a significant increase in caspase activity in fludarabine-treated p53-mutant MEG-01 cells, suggesting that miR-21 and miR-222 up-regulation may be involved in the establishment of fludarabine resistance. fludarabine 265-276 P53 Homo sapiens 151-154 21663679-3 2011 RESULTS: It is shown that vitamin K3- or vitamin C- induced apoptosis in leukemia cells by oxidative stress mechanism involving superoxide anion radical and hydrogen peroxide generation, activation of NF-kappaB, p53, c-Jun, protease caspase-3 activation and mitochondria depolarization leading to nuclei fragmentation. Ascorbic Acid 41-50 P53 Homo sapiens 212-215 17496931-5 2007 We demonstrate that in addition to topotecan (TPT), a known inhibitor of HIF-1alpha, UVC, but not other DNA damaging agents (cisplatin, ionizing radiation and doxorubicin), inhibited HIF-1alpha protein accumulation in a dose-dependent, p53-independent fashion. Topotecan 46-49 P53 Homo sapiens 236-239 23556086-11 2011 The only group that can be clearly identified pretreatment for whom conventional fludarabine-based therapies produce significantly inferior response rates, PFS and overall survival are the patients who harbour a genetic fault; deletion or mutation or a combination of deletion and mutation of tumour protein p53 (TP53). fludarabine 81-92 P53 Homo sapiens 308-311 17610067-5 2007 In the sensitive cell line an upregulation of multiple E2F1- and p53-inducible proapaptotic and cell-cycle regulating target genes by Topotecan as well as TRAIL was observed. Topotecan 134-143 P53 Homo sapiens 65-68 21162257-3 2007 RESULTS: In the group of a 12 h long exposure to oxygen concentration of 0%, diazoxide (100 micromol/L), the K(ATP) channels agonist, reduced p53 expression and the hypoxia-induced apoptosis. Diazoxide 77-86 P53 Homo sapiens 142-145 21162257-4 2007 In contrast, tolbutamide (100 micromol/L), the K(ATP) channels antagonist, significantly rose p53 expression and the hypoxia-induced apoptosis, which could be reversed by p53 inhibitor TSA. Tolbutamide 13-24 P53 Homo sapiens 94-97 21162257-4 2007 In contrast, tolbutamide (100 micromol/L), the K(ATP) channels antagonist, significantly rose p53 expression and the hypoxia-induced apoptosis, which could be reversed by p53 inhibitor TSA. Tolbutamide 13-24 P53 Homo sapiens 171-174 19960411-4 2010 In addition, 24-hydroxyursolic acid induced cellular apoptosis by activation of poly(ADP-ribose) polymerase (PARP), caspase-3, and phosphorylation of p53 at Ser15. 24-hydroxyursolic acid 13-35 P53 Homo sapiens 150-153 23556086-11 2011 The only group that can be clearly identified pretreatment for whom conventional fludarabine-based therapies produce significantly inferior response rates, PFS and overall survival are the patients who harbour a genetic fault; deletion or mutation or a combination of deletion and mutation of tumour protein p53 (TP53). fludarabine 81-92 P53 Homo sapiens 313-317 23556086-12 2011 TP53 inactivation is a less common finding at first treatment but becomes much more common in fludarabine-refractory patients. fludarabine 94-105 P53 Homo sapiens 0-4 21277290-8 2011 As for the 47 IotaIotaIota stage NSCLC treated with NACT, s-p53 Abs and CA12-5 remarkably decreased after NACT treatment (P=0.034 and P=0.007) and pre-NACT low s-p53 Abs correlated with high objective chemoresponse rate (P=0.016). nact 52-56 P53 Homo sapiens 60-63 20045437-6 2010 Simvastatin increased expression of Bax, oligomerization of Bax and Bak, and expression of BH3-only p53-dependent genes, PUMA and NOXA. Simvastatin 0-11 P53 Homo sapiens 100-103 20045437-7 2010 Inhibition of p53 and silencing of p53 unregulated modulator of apoptosis (PUMA) expression partly counteracted simvastatin-induced cell death, suggesting a role for p53-independent mechanisms. Simvastatin 112-123 P53 Homo sapiens 35-38 20045437-7 2010 Inhibition of p53 and silencing of p53 unregulated modulator of apoptosis (PUMA) expression partly counteracted simvastatin-induced cell death, suggesting a role for p53-independent mechanisms. Simvastatin 112-123 P53 Homo sapiens 35-38 20045437-10 2010 Thus, simvastatin activates novel apoptosis pathways in lung mesenchymal cells involving p53, IAP inhibitor release, and disruption of mitochondrial fission. Simvastatin 6-17 P53 Homo sapiens 89-92 20535395-7 2007 Further western blot analysis showed that ascorbic acid treatment decreased levels of p53, phospho-p53 at ser 15, and p21, indicating that ascorbic acid relieved senescence-related G1 arrest. Ascorbic Acid 42-55 P53 Homo sapiens 86-89 20535395-7 2007 Further western blot analysis showed that ascorbic acid treatment decreased levels of p53, phospho-p53 at ser 15, and p21, indicating that ascorbic acid relieved senescence-related G1 arrest.

Formaldehyde 0-8 P53 Homo sapiens 72-75 20036271-6 2010 This laboratory demonstrated earlier that in cells treated with arsenite, the P53-dependent increase in p21(WAF1/CIP1) expression, normally a block to cell cycle progression after DNA damage, is deficient. arsenite 64-72 P53 Homo sapiens 78-81 21292642-4 2011 We found that prolonged exposure of immortalized p53-knocked down human bronchial epithelial cells (p53(low)HBECs) to low levels of arsenite (NaAsO2, 2.5 muM) caused malignant transformation that was accompanied by epithelial to mesenchymal transition (EMT) and reduction in the levels of miR-200 family members. arsenite 132-140 P53 Homo sapiens 49-52 20036271-7 2010 Here we show that although long-term exposure of human keratinocytes (HaCaT) to a nontoxic concentration (0.1 microM) of arsenite decreases the level of global protein poly(ADP-ribosyl)ation, it increases poly(ADP-ribosyl)ation of P53 protein and PARP-1 protein abundance. arsenite 121-129 P53 Homo sapiens 231-234 20036271-10 2010 Our results suggest that arsenite"s interference with activation of P53 via poly(ADP-ribosyl)ation may play a role in the comutagenic and cocarcinogenic effects of arsenite. arsenite 25-33 P53 Homo sapiens 68-71 19931552-0 2010 Arsenite promotes centrosome abnormalities under a p53 compromised status induced by 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). arsenite 0-8 P53 Homo sapiens 51-54 19931552-7 2010 NNK treatment could also reduce arsenite-induced G2/M cell cycle arrest and apoptosis, these cellular effects were found to be correlated with p53 dysfunction. arsenite 32-40 P53 Homo sapiens 143-146 19931552-10 2010 Arsenite would act specifically on this p53 compromised status to induce centrosomal abnormality and colony formation. arsenite 0-8 P53 Homo sapiens 40-43 17150195-13 2007 Collectively, we conclude that D-501036 induces cellular apoptosis through the p53-associated mitochondrial pathway. 2,5-bis(5-hydroxymethyl-2-selenienyl)-3-hydroxymethyl-N-methylpyrrole 31-39 P53 Homo sapiens 79-82 17263498-0 2007 6-shogaol (alkanone from ginger) induces apoptotic cell death of human hepatoma p53 mutant Mahlavu subline via an oxidative stress-mediated caspase-dependent mechanism. alkanone 11-19 P53 Homo sapiens 80-83 21292642-4 2011 We found that prolonged exposure of immortalized p53-knocked down human bronchial epithelial cells (p53(low)HBECs) to low levels of arsenite (NaAsO2, 2.5 muM) caused malignant transformation that was accompanied by epithelial to mesenchymal transition (EMT) and reduction in the levels of miR-200 family members. arsenite 132-140 P53 Homo sapiens 100-103 21292642-6 2011 Moreover, stably expressing miR-200b alone in parental nontransformed p53(low)HBECs was sufficient to completely prevent arsenite exposure from inducing EMT and malignant transformation. arsenite 121-129 P53 Homo sapiens 70-73 20130960-0 2011 Perifosine selectively induces cell cycle block and modulates retinoblastoma and E2F1 protein levels in p53 mutated leukemic cell lines. perifosine 0-10 P53 Homo sapiens 104-107 17234448-4 2007 9-HSA administration to U2OS, an osteosarcoma cell line p53 wt, induces a growth arrest of the cells in G2/M and apoptosis via a mitochondrial pathway. 9-hydroxystearic acid 0-5 P53 Homo sapiens 56-59 17234448-5 2007 In particular hyperacetylation of p53 induced by the HDAC1 inhibitory activity of 9-HSA has been demonstrated to increase Bax synthesis both at the transcriptional and the translational level. 9-hydroxystearic acid 82-87 P53 Homo sapiens 34-37 17234448-7 2007 Our data demonstrate that the effects of 9-HSA on U2OS correlate with posttranslational modifications of p53. 9-hydroxystearic acid 41-46 P53 Homo sapiens 105-108 17325891-8 2007 In conclusion, 17p deletion, which causes loss of p53 gene, is associated with resistance to fludarabine-induced apoptosis in vitro. fludarabine 93-104 P53 Homo sapiens 50-53 19966562-1 2010 Pentamidine is a small molecule inhibitor of the Ca(+)-binding protein S100B and disrupts the S100B-p53 protein-protein interaction; this is thought to restore wild-type p53 tumour suppressor function in melanoma. Pentamidine 0-11 P53 Homo sapiens 100-103 19966562-1 2010 Pentamidine is a small molecule inhibitor of the Ca(+)-binding protein S100B and disrupts the S100B-p53 protein-protein interaction; this is thought to restore wild-type p53 tumour suppressor function in melanoma. Pentamidine 0-11 P53 Homo sapiens 170-173 20130960-2 2011 Perifosine promoted cytotoxicity with a combination of apoptosis induction in all cell lines and cell cycle block at the G(2)M checkpoint, which was selectively observed in p53(mutated) BJAB and MAVER cell lines. perifosine 0-10 P53 Homo sapiens 173-176 19727716-15 2010 Transfection of the NIS gene into human anaplastic thyroid cancer induced the accumulation of beta-emitter radionuclides, and cotransfection with a wt-p53 gene enhanced the cytotoxic effect. Nickel 20-23 P53 Homo sapiens 151-154 17135250-6 2007 Moreover, HCT116 colon cancer cells exhibited a p53-dependent sensitivity to PpIX in a dose-dependent manner, as was demonstrated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and fluorescence-activated cell sorter (FACS) analysis of cell cycle profiles. thiazolyl blue 136-196 P53 Homo sapiens 48-51 20130960-3 2011 At the molecular level, perifosine induced hypophosphorylation of retinoblastoma protein and the degradation of E2F1 protein in p53(mutated) but not in p53(wild-type) cells. perifosine 24-34 P53 Homo sapiens 128-131 20130960-4 2011 These data indicate that perifosine potentially represents an innovative therapeutic approach for p53(mutated) hematological malignancies. perifosine 25-35 P53 Homo sapiens 98-101 17182066-0 2007 Taiwanin A induced cell cycle arrest and p53-dependent apoptosis in human hepatocellular carcinoma HepG2 cells. taiwanin A 0-10 P53 Homo sapiens 41-44 19933157-6 2010 Binding of the probe bis-ANS (bis-8-anilinonaphthalene-1-sulfonate) indicates that there is an increase in the exposure of hydrophobic pockets for both wt and mutant p53C at low pH. bis-8-anilinonaphthalene-1-sulfonate 30-66 P53 Homo sapiens 166-169 21030860-5 2011 p53 and phospho-Histone3 (mitotic marker) showed increased staining in higher grade phyllodes tumors. phyllodes 84-93 P53 Homo sapiens 0-3 20048077-3 2010 We compared the effects of vanadate to PFTalpha and PFTmicro, an inhibitor of transcription-independent apoptosis by p53. pftmicro 52-60 P53 Homo sapiens 117-120 20500145-8 2010 Finally, ursodeoxycholic acid (UDCA), an endogenous bile acid used to treat cholestatic liver diseases, was recently described as a fine modulator of the complex control of p53 by Mdm-2. Ursodeoxycholic Acid 9-29 P53 Homo sapiens 173-176 19812371-0 2010 Topotecan triggers apoptosis in p53-deficient cells by forcing degradation of XIAP and survivin thereby activating caspase-3-mediated Bid cleavage. Topotecan 0-9 P53 Homo sapiens 32-35 17352246-6 2007 RESULTS: Ascorbic acid was found to reduce the proliferation of cells and induce apoptosis by the modulation of p53, p21, Bcl-2 and Bax. Ascorbic Acid 9-22 P53 Homo sapiens 112-115 17136320-6 2007 Most importantly, sulindac-derived ROS activated p38 mitogen-activated protein kinase and p53. Sulindac 18-26 P53 Homo sapiens 90-93 17136320-7 2007 SB203580, a p38 mitogen-activated protein kinase inhibitor, and RNA inhibition of p53 inhibited the sulindac-induced apoptosis. Sulindac 100-108 P53 Homo sapiens 82-85 19812371-2 2010 We previously showed that TPT-induced apoptosis depends on p53 with p53 wild-type (wt) cells being more resistant because of p53-controlled degradation of topoisomerase I. Topotecan 26-29 P53 Homo sapiens 59-62 21145583-8 2011 TEGDMA (3 mm) appeared to stimulate p53 expression only slightly, but increased p21 expression was found in cell nuclei and cytoplasm. triethylene glycol dimethacrylate 0-6 P53 Homo sapiens 36-39 19812371-2 2010 We previously showed that TPT-induced apoptosis depends on p53 with p53 wild-type (wt) cells being more resistant because of p53-controlled degradation of topoisomerase I. Topotecan 26-29 P53 Homo sapiens 68-71 19812371-2 2010 We previously showed that TPT-induced apoptosis depends on p53 with p53 wild-type (wt) cells being more resistant because of p53-controlled degradation of topoisomerase I. Topotecan 26-29 P53 Homo sapiens 68-71 19812371-13 2010 Overall, the data show that p53-deficient/depleted cells are hypersensitive to TPT because they down-regulate XIAP and survivin, and thus amplify the intrinsic apoptotic pathway via caspase-3-mediated Bid cleavage. Topotecan 79-82 P53 Homo sapiens 28-31 17136320-8 2007 Furthermore, p53, Bax, and Bak accumulated in mitochondria during sulindac-induced apoptosis. Sulindac 66-74 P53 Homo sapiens 13-16 17136320-10 2007 Our results demonstrate a novel mechanism of sulindac-induced apoptosis in human MM cells, namely, accumulation of p53, Bax, and Bak in mitochondria mediated by p38 MAPK activation downstream of ROS production. Sulindac 45-53 P53 Homo sapiens 115-118 19812371-14 2010 Therefore, in gliomas harboring wild-type p53, TPT-based therapy might be improved by targeted down-regulation of XIAP and survivin. Topotecan 47-50 P53 Homo sapiens 42-45 21145583-9 2011 Both camptothecin and TEGDMA increased p53 expression to some extent in the nuclear fraction in human transformed pulp-derived cells (tHPC), and similar effects were detected in RAW264.7 macrophages. triethylene glycol dimethacrylate 22-28 P53 Homo sapiens 39-42 20974702-5 2011 This is because the effect of p53 in CoCl(2)-treated monocytes is counteracted by the antiapoptotic activity of cytoplasmic p21(Cip1/WAF1), the activation of nuclear factor kappaB, and the inflammasome danger signaling pathway leading to the production of proinflammatory cytokines. cobaltous chloride 37-44 P53 Homo sapiens 30-33 19744477-5 2009 Pre-treating cells with the antioxidant ascorbic acid not only prohibited the induction of reactive oxygen species by emodin, but also inhibited the up-regulation of p53. Ascorbic Acid 40-53 P53 Homo sapiens 166-169 17245120-7 2007 We also analyzed the antiproliferative effects of the bile pigments in an in vitro system where bilirubin/biliverdin caused p53 dependent cell cycle arrest by hypophosphorylation of the retinoblastoma tumor suppressor protein in growth factor stimulated VSMCs. Bilirubin 96-105 P53 Homo sapiens 124-127 21304979-8 2011 Notably both mevalonate cascade inhibition-induced autophagy and apoptosis were p53 dependent: simvastatin increased nuclear p53 accumulation, and both cyclic pifithrin-alpha and p53 shRNAi partially inhibited NOXA, PUMA expression and caspase-3/7 cleavage (apoptosis) and DRAM expression, Atg5-12 complex formation, LC3 lipidation, and autophagosome formation (autophagy). Simvastatin 95-106 P53 Homo sapiens 80-83 17060456-11 2007 These studies demonstrate that activation of PI3K signaling by mutations in PTEN or PIK3CA can lead to activation of p53-mediated growth suppression in human cells, indicating that p53 can function as a brake on phosphatidylinositol (3,4,5)-triphosphate-induced mitogenesis during human cancer pathogenesis. phosphatidylinositol 3,4,5-triphosphate 212-253 P53 Homo sapiens 117-120 17060456-11 2007 These studies demonstrate that activation of PI3K signaling by mutations in PTEN or PIK3CA can lead to activation of p53-mediated growth suppression in human cells, indicating that p53 can function as a brake on phosphatidylinositol (3,4,5)-triphosphate-induced mitogenesis during human cancer pathogenesis. phosphatidylinositol 3,4,5-triphosphate 212-253 P53 Homo sapiens 181-184 19787260-0 2009 Organophosphorous pesticides and estrogen induce transformation of breast cells affecting p53 and c-Ha-ras genes. organophosphorous 0-17 P53 Homo sapiens 90-93 19787260-13 2009 It can be concluded that the organophosphorous pesticides parathion and malathion induced malignant transformation of breast cells through genomic instability altering p53 and c-Ha-ras, considered pivotal to cancer process. organophosphorous 29-46 P53 Homo sapiens 168-171 21304979-8 2011 Notably both mevalonate cascade inhibition-induced autophagy and apoptosis were p53 dependent: simvastatin increased nuclear p53 accumulation, and both cyclic pifithrin-alpha and p53 shRNAi partially inhibited NOXA, PUMA expression and caspase-3/7 cleavage (apoptosis) and DRAM expression, Atg5-12 complex formation, LC3 lipidation, and autophagosome formation (autophagy). Simvastatin 95-106 P53 Homo sapiens 125-128 19787260-13 2009 It can be concluded that the organophosphorous pesticides parathion and malathion induced malignant transformation of breast cells through genomic instability altering p53 and c-Ha-ras, considered pivotal to cancer process. Parathion 58-67 P53 Homo sapiens 168-171 19787260-13 2009 It can be concluded that the organophosphorous pesticides parathion and malathion induced malignant transformation of breast cells through genomic instability altering p53 and c-Ha-ras, considered pivotal to cancer process. Malathion 72-81 P53 Homo sapiens 168-171 21304979-8 2011 Notably both mevalonate cascade inhibition-induced autophagy and apoptosis were p53 dependent: simvastatin increased nuclear p53 accumulation, and both cyclic pifithrin-alpha and p53 shRNAi partially inhibited NOXA, PUMA expression and caspase-3/7 cleavage (apoptosis) and DRAM expression, Atg5-12 complex formation, LC3 lipidation, and autophagosome formation (autophagy). Simvastatin 95-106 P53 Homo sapiens 125-128 19822456-3 2009 In addition, recent work has provided new insights into mechanisms underlying the antiapoptotic functions of the endogenous bile acid ursodeoxycholic acid (UDCA), suggesting that the finely tuned, complex control of p53 by Mdm2 is a key step in the UDCA modulation of deregulated, p53-triggered apoptosis. Ursodeoxycholic Acid 134-154 P53 Homo sapiens 216-219 17119452-11 2006 The increased expressions of p53 and p21, and the decreased expressions of cyclin A, cyclin E, CDK2 and CDK4, indicated the cell cycle arrest at G1/S phase after the cells had been treated with sodium ascorbate. Ascorbic Acid 194-210 P53 Homo sapiens 29-32 17119452-12 2006 Induction of apoptosis involved an increase in the levels of p53, p21 and cellular Ca, and a decrease in mitochondrial membrane potential and activation of caspase 3 before culminating in apoptosis in sodium ascorbate-treated A375.S2 cells. Ascorbic Acid 201-217 P53 Homo sapiens 61-64 19822456-3 2009 In addition, recent work has provided new insights into mechanisms underlying the antiapoptotic functions of the endogenous bile acid ursodeoxycholic acid (UDCA), suggesting that the finely tuned, complex control of p53 by Mdm2 is a key step in the UDCA modulation of deregulated, p53-triggered apoptosis.

Sulindac 139-147 P53 Homo sapiens 81-84 16950207-6 2006 Combined sulindac/ATO treatment also activated p53 expression, and inhibition of p53 expression by small interfering RNA (siRNA) prevented sulindac/ATO-induced down-regulation of survivin, suggesting that survivin expression is negatively regulated by p53. Sulindac 139-147 P53 Homo sapiens 81-84 16882877-4 2006 The induction of WI38 cell senescence by Etop was associated with p53 activation and could be attenuated by down-regulation of p53 using alpha-pifithrin (alpha-PFT) or p53 small interference RNA (siRNA). alpha-pifithrin 137-152 P53 Homo sapiens 127-130 16882877-4 2006 The induction of WI38 cell senescence by Etop was associated with p53 activation and could be attenuated by down-regulation of p53 using alpha-pifithrin (alpha-PFT) or p53 small interference RNA (siRNA). alpha-pifithrin 137-152 P53 Homo sapiens 127-130 21220492-4 2011 In this study, we report that pancratistatin decreased mitochondrial membrane potential and induced apoptotic nuclear morphology in p53-mutant (HT-29) and wild-type p53 (HCT116) colorectal carcinoma cell lines, but not in noncancerous colon fibroblast (CCD-18Co) cells. pancratistatin 30-44 P53 Homo sapiens 132-135 16979516-13 2006 Lipofuscin probably indicates slow cellular turnover as suggested by the low proliferation rate and p53 expression. Lipofuscin 0-10 P53 Homo sapiens 100-103 19470404-1 2009 Arsenite effects on the benzo[a]pyrene diol epoxide (BPDE)-DNA adduct-induced mutation were evaluated in three human lung cell-lines--A549 (wild-type p53), WI38-VA13 (p53 inhibited by SV40 large-T antigen), and H1299 (p53-null)--by using the pSP189 shuttle vector, which carries a mutation target supF gene. arsenite 0-8 P53 Homo sapiens 167-170 19470404-1 2009 Arsenite effects on the benzo[a]pyrene diol epoxide (BPDE)-DNA adduct-induced mutation were evaluated in three human lung cell-lines--A549 (wild-type p53), WI38-VA13 (p53 inhibited by SV40 large-T antigen), and H1299 (p53-null)--by using the pSP189 shuttle vector, which carries a mutation target supF gene. arsenite 0-8 P53 Homo sapiens 167-170 19470404-5 2009 These results suggest that arsenite potentiates the BPDE-induced supF mutation via a p53-independent mechanism. arsenite 27-35 P53 Homo sapiens 85-88 21220492-4 2011 In this study, we report that pancratistatin decreased mitochondrial membrane potential and induced apoptotic nuclear morphology in p53-mutant (HT-29) and wild-type p53 (HCT116) colorectal carcinoma cell lines, but not in noncancerous colon fibroblast (CCD-18Co) cells. pancratistatin 30-44 P53 Homo sapiens 165-168 21110861-8 2010 The Meq variants L-Meq and S-Meq, but not VS-Meq and Meq, which were expressed in MD tumor cells and MDV-infected cells, exerted an inhibitory effect on p53 transcriptional activity. l-meq 17-22 P53 Homo sapiens 154-157 19435284-2 2009 The p53 antibody molecules immobilized on an (R)-lipo-diaza-18-crown-6 self-assembled monolayer (SAM)-modified gold disk electrode were shown to effectively capture the p53 protein by Western blot, quartz crystal microbalance, and electrochemical impedance experiments.

(2)o(3) 14-21 P53 Homo sapiens 144-147 16945145-5 2006 A variety of data has revealed a critical role for p53-binding protein 1 (53BP1) in the cellular response to DSBs including various aspects of p53 function. dsbs 109-113 P53 Homo sapiens 51-54 20708793-0 2010 The effect of triethylene glycol dimethacrylate on p53-dependent G2 arrest in human gingival fibroblasts. triethylene glycol dimethacrylate 14-47 P53 Homo sapiens 51-54 16814620-13 2006 Moreover, cells from this panel with wild-type p53 showed a significantly lower background level of gammaH2AX than cells with mutant p53. gammah2ax 100-109 P53 Homo sapiens 47-50 16814620-15 2006 Again, higher gammaH2AX expression was found in SKOV3 cell lines expressing mutant p53 compared to wild-type p53. gammah2ax 14-23 P53 Homo sapiens 83-86 19100681-8 2009 Increased PDF mRNA stability in response to hypoxia and cobalt chloride, but not doxorubicin, indicates that p53-dependent induction of PDF expression occurs via diverse mechanisms. cobaltous chloride 56-71 P53 Homo sapiens 109-112 19417156-7 2009 Saq-NO blocked the proliferation of C6 and B16 cells, up-regulated p53 expression, and promoted the differentiation of these two cell types into oligodendrocytes or Schwann-like cells, respectively. saq-no 0-6 P53 Homo sapiens 67-70 16814620-15 2006 Again, higher gammaH2AX expression was found in SKOV3 cell lines expressing mutant p53 compared to wild-type p53. gammah2ax 14-23 P53 Homo sapiens 109-112 16574813-4 2006 Results from our current study show that GM3 treatment dramatically increases cyclin-dependent kinase (CDK) inhibitor (CKI) p21(WAF1) expression through the accumulation of p53 protein by the PTEN-mediated inhibition of the PI-3K/AKT/MDM2 survival signaling in HCT116 colon cancer cells. gm3 41-44 P53 Homo sapiens 173-176 16574813-5 2006 Moreover, the data herein clearly show that ganglioside GM3 induces p53-dependent transcriptional activity of p21(WAF1), as evidenced by the p21(WAF1) promoter-driven luciferase reporter plasmid (full-length p21(WAF1) promoter and a construct lacking the p53-binding sites). gm3 56-59 P53 Homo sapiens 68-71 21035481-3 2010 We found that salidroside considerably reversed senescence-like phenotypes in the oxidant challenged model, including alterations of morphology, cell cycle, SA-beta-gal staining, DNA damage, as well as related molecules expression such as p53, p21 and p16. rhodioloside 14-25 P53 Homo sapiens 239-242 16614167-0 2006 p53 suppression of arsenite-induced mitotic catastrophe is mediated by p21CIP1/WAF1. arsenite 19-27 P53 Homo sapiens 0-3 16614167-3 2006 Arsenite sensitivity correlates with deficient p53 pathways in multiple cell lines. arsenite 0-8 P53 Homo sapiens 47-50 16614167-4 2006 The role of p53 in preventing arsenite-induced mitotic arrest-associated apoptosis (MAAA), a form of mitotic catastrophe, was examined in TR9-7 cells, a model cell line with p53 exogenously regulated in a tetracycline-off expression system. arsenite 30-38 P53 Homo sapiens 12-15 19331830-4 2009 Two human p14ARF residues (Ala(14) and Thr(31)) were found to destabilize the protein while two others (Val(24) and Ala(41)) promoted more efficient p53 stabilization and activation. Valine 104-107 P53 Homo sapiens 149-152 19331830-7 2009 Val(24) was required for p53-independent growth suppression whereas multiple residues (Val(24), Thr(31), Ala(41) and His(60)) enabled p14ARF to block or reverse the inherent chromosomal instability of p53-null MEFs. Valine 0-3 P53 Homo sapiens 25-28 20619728-7 2010 The mRNA and protein level of p53 was significantly higher in high fluoride+high selenium group than that in other two groups. Fluorides 67-75 P53 Homo sapiens 30-33 19243593-4 2009 However, both p53-positive and -negative cells arrest in mitosis if treated with low doses of siRNA against NEDD1 combined with low doses of the inhibitor BI2536 against the mitotic kinase Plk1. BI 2536 155-161 P53 Homo sapiens 14-17 19155291-1 2009 The major determinants of 5-flurouracil (5-FU) response would seem, based on accumulated literature, to be thymidylate synthase (TYMS, TS) expression levels, TS gene modifications, and TP53 status. 5-flurouracil 26-39 P53 Homo sapiens 185-189 19155295-6 2009 Down-regulation of CtBPs mediated by some tumor suppressors results in p53-independent apoptosis and reduced tumor cell migration and invasion. ctbps 19-24 P53 Homo sapiens 71-74 16443387-5 2006 Trypan blue and acridine orange/ethidium bromide staining were carried out, as well as quantitative analysis of the apoptotic signal of P53 and BAX induction caused by the cis-Pt(II) complex of 3-aminoflavone in comparison with cis-DDP. 3-aminoflavone 194-208 P53 Homo sapiens 136-139 16585172-11 2006 As a measure of DNA glycosylase activity, p53+/+ mitochondrial extracts more efficiently incised uracil or 8-oxo-G oligonucleotides, although recombinant p53 could not stimulate oligonucleotide incision. 8-oxo-g oligonucleotides 107-131 P53 Homo sapiens 42-45 19155295-8 2009 The results discussed here suggest that CtBPs may constitute a novel p53-independent anticancer target. ctbps 40-45 P53 Homo sapiens 69-72 20662736-7 2010 Anthracycline (topoisomerase II inhibitors such as mitoxantrone and ellipticine) and camptothecin (topoisomerase I inhibitor) derivatives including topotecan induce DNA double strand breaks, which activate the p53 pathway through the ataxia telangiectasia mutated-checkpoint kinase 2 (ATM-CHK2) DNA damage response pathway. Topotecan 148-157 P53 Homo sapiens 210-213 16533058-2 2006 However, we previously showed that cells lacking ATM robustly activate p53 in response to DNA strand breaks induced by the radiomimetic enediyne C-1027. C 1027 145-151 P53 Homo sapiens 71-74 25961194-3 2010 The cells grown in charcoal-treated serum were treated with 1 nM E2 or different concentrations of LY117018 for 24 h. E2 or LY117018 treatments caused a 2- to 3-fold increase in the level of p53 and hyperphosphorylation of pRb. LY 117018 99-107 P53 Homo sapiens 191-194 16582987-2 2006 We studied sequence-specific interaction of the vinyl-chloride metabolite CAA with human p53 gene exons 5-8, using DNA Polymerase Fingerprint Analysis (DPFA), and identified sites of the highest sensitivity. Chlorides 54-62 P53 Homo sapiens 89-92 19042973-3 2009 The remarkable similarity in p53 mutations found in human gastrointestinal tumors and in shuttle vector studies, where the human p53 gene-containing vector was treated with diazoacetate and propagated in yeast cells, suggests that diazoacetate might be an important etiological agent for human gastrointestinal tumors. diazoacetate 173-185 P53 Homo sapiens 129-132 19042973-3 2009 The remarkable similarity in p53 mutations found in human gastrointestinal tumors and in shuttle vector studies, where the human p53 gene-containing vector was treated with diazoacetate and propagated in yeast cells, suggests that diazoacetate might be an important etiological agent for human gastrointestinal tumors. diazoacetate 231-243 P53 Homo sapiens 29-32 19042973-3 2009 The remarkable similarity in p53 mutations found in human gastrointestinal tumors and in shuttle vector studies, where the human p53 gene-containing vector was treated with diazoacetate and propagated in yeast cells, suggests that diazoacetate might be an important etiological agent for human gastrointestinal tumors. diazoacetate 231-243 P53 Homo sapiens 129-132 17310826-6 2006 In conclusion, these data show that specific HIV PIs such as lopinavir and possibly indinavir, can induce selective toxicity of HPV-transformed cervical carcinoma cells expressing wild-type p53 and may form the basis of a topically applied alternative to surgery for the treatment of HPV-related premalignant lesions of the cervix. Monothiopyrophosphoric acid 49-52 P53 Homo sapiens 190-193 17310826-6 2006 In conclusion, these data show that specific HIV PIs such as lopinavir and possibly indinavir, can induce selective toxicity of HPV-transformed cervical carcinoma cells expressing wild-type p53 and may form the basis of a topically applied alternative to surgery for the treatment of HPV-related premalignant lesions of the cervix. Indinavir 84-93 P53 Homo sapiens 190-193 25961194-3 2010 The cells grown in charcoal-treated serum were treated with 1 nM E2 or different concentrations of LY117018 for 24 h. E2 or LY117018 treatments caused a 2- to 3-fold increase in the level of p53 and hyperphosphorylation of pRb. LY 117018 124-132 P53 Homo sapiens 191-194 25961194-6 2010 Thus, LY117018 treatment induces changes in the level/activity of p53 and pRb and ultrastructure of T47D cells. LY 117018 6-14 P53 Homo sapiens 66-69 19950227-6 2010 Risk of TP53 mutation was significantly increased in association with duration (> or =24 years, OR 5.1, 95% CI, 1.5-17.1), average level (>2 mg/m(3); OR 3.6, 95% CI, 1.2-10.8) and cumulative level (> or =30 mg/m(3) x years; OR 3.5, 95% CI, 1.2-10.7) of wood-dust exposure; adjustment for formaldehyde affected the ORs only slightly. Formaldehyde 297-309 P53 Homo sapiens 8-12 16297852-6 2006 However, mutant p53(143ala) increased the sensitivity of MRC-5 to C(2)-ceramide-induced apoptosis by markedly downregulating Bcl-2, pointing to a role for p53. A(2)C 66-70 P53 Homo sapiens 16-19 19028473-0 2009 Kaempferol induces apoptosis in human HCT116 colon cancer cells via the Ataxia-Telangiectasia Mutated-p53 pathway with the involvement of p53 Upregulated Modulator of Apoptosis. kaempferol 0-10 P53 Homo sapiens 102-105 19028473-0 2009 Kaempferol induces apoptosis in human HCT116 colon cancer cells via the Ataxia-Telangiectasia Mutated-p53 pathway with the involvement of p53 Upregulated Modulator of Apoptosis. kaempferol 0-10 P53 Homo sapiens 138-141 19028473-3 2009 In the human HCT116 colon cancer cell line, kaempferol induced p53-dependent growth inhibition and apoptosis. kaempferol 44-54 P53 Homo sapiens 63-66 16889904-0 2006 Correlation of p53 and MIB-1 expression with both the systemic recurrence and survival in cases of phyllodes tumors of the breast. phyllodes 99-108 P53 Homo sapiens 15-18 19022222-4 2009 Here we show that Ets-1 also binds cooperatively to the EBS palindrome of the human p53 promoter, despite the presence of a degenerate EBS to which Ets-1 cannot otherwise bind. ethylbenzene 56-59 P53 Homo sapiens 84-87 20566882-0 2010 Pyrimidine biosynthesis links mitochondrial respiration to the p53 pathway. pyrimidine 0-10 P53 Homo sapiens 63-66 16889904-9 2006 Positive staining for p53 was seen in 10 phyllodes tumors (24%), and the median MIB-1 index was 10%. phyllodes 41-50 P53 Homo sapiens 22-25 20566882-8 2010 The results establish the deficiency in pyrimidine biosynthesis as the cause of p53 response in the cells with impaired mitochondrial respiration. pyrimidine 40-50 P53 Homo sapiens 80-83 16157218-1 2005 Recently, we have reported that a synthetic derivative of ursodeoxycholic acid (UDCA), HS-1183, and those of chenodeoxycholic acid (CDCA), HS-1199 and HS-1200, induced apoptosis in human breast carcinoma cells through a p53-independent pathway. Ursodeoxycholic Acid 58-78 P53 Homo sapiens 220-223 16157218-1 2005 Recently, we have reported that a synthetic derivative of ursodeoxycholic acid (UDCA), HS-1183, and those of chenodeoxycholic acid (CDCA), HS-1199 and HS-1200, induced apoptosis in human breast carcinoma cells through a p53-independent pathway. Ursodeoxycholic Acid 80-84 P53 Homo sapiens 220-223 19778838-2 2009 Dysfunction of p53 leads to resistance to fludarabine-based therapies. fludarabine 42-53 P53 Homo sapiens 15-18 20657652-4 2010 METHODOLOGY/PRINCIPAL FINDINGS: In this study, we show that DCB-3503 suppresses the expression of pro-oncogenic or pro-survival proteins with short half-lives, including cyclin D1, survivin, beta-catenin, p53, and p21, without decreasing their mRNA levels. DCB 3503 60-68 P53 Homo sapiens 205-208 19062342-4 2008 In contrast, chlorambucil and fludarabine resistance correlated with basal p53 protein levels. fludarabine 30-41 P53 Homo sapiens 75-78 16157218-1 2005 Recently, we have reported that a synthetic derivative of ursodeoxycholic acid (UDCA), HS-1183, and those of chenodeoxycholic acid (CDCA), HS-1199 and HS-1200, induced apoptosis in human breast carcinoma cells through a p53-independent pathway.

Simvastatin 19-30 P53 Homo sapiens 87-90 18804536-9 2008 In conclusion, simvastatin inhibits VSMC proliferation in high glucose status, mimicking diabetes, inducing a G0/G1 phase cell cycle growth arrest by acting on multiple steps upstream of pRb, including inhibition of CDK2/4 expression and up-regulation of p53, p21, p16, and p27. Simvastatin 15-26 P53 Homo sapiens 255-258 20138958-6 2010 Iodine treatment decreased the level of mutant p53 including the R273H mutant that possesses anti-apoptotic features, but increased the p21 level. Iodine 0-6 P53 Homo sapiens 47-50 20138958-8 2010 Moreover, iodine transiently activated the subfamily members of mitogen activated protein kinases (MAPKs) (ERK1/2, p38 and JNK1/2) which contribute to modulate p53, p21 and Bcl-xL expression. Iodine 10-16 P53 Homo sapiens 160-163 18401588-7 2008 Compared with UVB irradiated cells, UVB-induced p53 accumulation was less pronounced in Baicalin-treated cells. baicalin 88-96 P53 Homo sapiens 48-51 20138958-10 2010 Collectively, iodine-induced apoptotic pathway is involved in the activation of MAPKs-related p21, Bcl-xL and mutant p53 regulation. Iodine 14-20 P53 Homo sapiens 117-120 20160501-7 2010 This inhibitory effect was not dependent on the status of p53 and p21 although GDP366 potently increased p53 and p21 levels. GDP 366 79-85 P53 Homo sapiens 105-108 18452313-11 2008 Mapping the sequence specificity of Cr(III)-GA 2- and Cr(III)-EGA 2-DNA formation in the human p53 gene sequence by UvrABC nuclease cutting, we found that the sequence specificity for both adducts is the same but is much more selective than Cr(III)-guanine-DNA adducts. tris(1,10-phenanthroline)chromium(III) chloride 54-61 P53 Homo sapiens 95-98 18266926-4 2008 We recently reported that PQ induces neuronal apoptosis through Bak activation, in contrast to MPP(+), the toxic metabolite of MPTP, which relies on Bax and p53. Paraquat 26-28 P53 Homo sapiens 157-160 18727380-4 2008 The treatment of selective inhibitors JNK SP600125 and p38 ML3403 in vitro prevents peroxide-induced appearance of P53 and NF-kB in blood mononuclear cells, associated with increasing of their apoptotic activity.

Topotecan 112-121 P53 Homo sapiens 137-140 18092340-5 2008 Analysis of the gene expression profile of the p53-transcriptional targets showed distinct features between chlorambucil, Nutlin-3 and fludarabine, which likely account for their differential effect on cell cycle in SKW6.4 cells. fludarabine 135-146 P53 Homo sapiens 47-50 20067818-8 2010 The antioxidant ascorbic acid inhibited BrO(3)(-)-induced p38 activation, G2/M arrest, p-p53, p21 and cyclin B1 expression; however, ascorbic acid had no effect on BrO(3)(-)-induced formation of 8-OHdG, a marker of DNA oxidative damage, whose increases preceded cell death by 24h. Ascorbic Acid 16-29 P53 Homo sapiens 89-92 18316341-5 2008 The enhanced expression of PTEN by GM3 in both HCT116 and p53-null HCT116 cells has been shown to be not associated with p53 function. gm3 35-38 P53 Homo sapiens 58-61 20000476-0 2010 Suppression of p53 and p21CIP1/WAF1 reduces arsenite-induced aneuploidy. arsenite 44-52 P53 Homo sapiens 15-18 18348286-2 2008 We have developed a high-throughput scanning assay with automatic calling to detect TP53 mutations in DNA from fresh frozen (FF) and formalin-fixed paraffin-embedded (FFPE) tissues. Formaldehyde 133-141 P53 Homo sapiens 84-88 17849503-7 2008 Moreover, arsenite induced the translocation of Bax and p53 to the mitochondria and the activation-associated oligomerization of Bax, and these crucial events were reduced by inhibition of GSK3, indicating that GSK3 promotes arsenite-induced apoptosis by facilitating signals leading to mitochondrial apoptotic events. arsenite 10-18 P53 Homo sapiens 56-59 20000476-7 2010 Although suppression of p53 increased the fraction of arsenite-treated cells with MN, it caused a decrease in the fraction with centromeric DNA. arsenite 54-62 P53 Homo sapiens 24-27 20557688-9 2010 In conclusion, the release of ROS by PU- or PTFE-treated THP-1 cells may induce iNOS expression and cause apoptosis in HUVECs via the p53, Bax and Bcl-2 proteins. Polyurethanes 37-39 P53 Homo sapiens 134-137 18226502-2 2008 OBJECTIVE: We aimed to investigate (1) the UV transmission through tacrolimus ointment and (2) the impact of topical exposure to tacrolimus on the protein expression of thymine dimers (TD) and p53 in human skin. Tacrolimus 129-139 P53 Homo sapiens 193-196 20211059-8 2010 NT4-p53(N15)-Ant on HepG2 cells was measured by a colorimetric 3-[4,5-dimethyl thiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. thiazolyl blue 63-124 P53 Homo sapiens 4-7 18504176-0 2008 [Construction and expression of different mutants of human p53 and their effects on arsenite-induced cell apoptosis]. arsenite 84-92 P53 Homo sapiens 59-62 18504176-6 2008 The apoptotic ratio of p53(WT)-transfected cells induced by arsenite increased and that of p53(S15A)-transfected cells decreased significantly after arsenite stimulation, but no significant changes occurred in the apoptosis of p53(S46A)-transfected cells. arsenite 60-68 P53 Homo sapiens 23-26 18504176-6 2008 The apoptotic ratio of p53(WT)-transfected cells induced by arsenite increased and that of p53(S15A)-transfected cells decreased significantly after arsenite stimulation, but no significant changes occurred in the apoptosis of p53(S46A)-transfected cells. arsenite 149-157 P53 Homo sapiens 91-94 18504176-6 2008 The apoptotic ratio of p53(WT)-transfected cells induced by arsenite increased and that of p53(S15A)-transfected cells decreased significantly after arsenite stimulation, but no significant changes occurred in the apoptosis of p53(S46A)-transfected cells. arsenite 149-157 P53 Homo sapiens 91-94 18504176-7 2008 CONCLUSION: The phosphorylation on Ser15 of p53 plays an important role in mediating arsenite-induced cell apoptosis. arsenite 85-93 P53 Homo sapiens 44-47 19009304-0 2009 Establishment of ponasterone A-inducible the wild-type p53 protein-expressing clones from HSC-1 cells, cell growth suppression by p53 expression and the suppression mechanism. ponasterone A 17-30 P53 Homo sapiens 55-58 18347187-7 2008 Cellular levels of ceramide, sphingomyelinase activity, caspase-3, and p53 were elevated with increasing time of exposure to alpha-TOS. alpha-tos 125-134 P53 Homo sapiens 71-74 15890420-1 2005 BACKGROUND AND PURPOSE: To elucidate the role of TP53 on differential effects of topoisomerase I inhibitor topotecan (Hycamtin on radiation sensitivity. Topotecan 107-116 P53 Homo sapiens 49-53 15890420-1 2005 BACKGROUND AND PURPOSE: To elucidate the role of TP53 on differential effects of topoisomerase I inhibitor topotecan (Hycamtin on radiation sensitivity. Topotecan 118-126 P53 Homo sapiens 49-53 15890420-4 2005 Phosphorylation of TP53 and expression of p21(WAF1/CIP1) was induced by IR and/or topotecan in CCD32 cells, and in U118 cells after topotecan treatment, accompanied by cyclin B degradation. Topotecan 82-91 P53 Homo sapiens 19-23 15890420-4 2005 Phosphorylation of TP53 and expression of p21(WAF1/CIP1) was induced by IR and/or topotecan in CCD32 cells, and in U118 cells after topotecan treatment, accompanied by cyclin B degradation. Topotecan 132-141 P53 Homo sapiens 19-23 15890420-5 2005 In U87 cells only 1 microM topotecan generated phosphorylation of TP53 and p21(WAF1/CIP1) expression; 0.05 microM caused stabilization of cyclin B. Topotecan 27-36 P53 Homo sapiens 66-70 15890420-7 2005 Thus, the impact of TP53 on the topotecan response remains indistinct, and is obviously influenced by other genomic alterations acquired by tumor cells. Topotecan 32-41 P53 Homo sapiens 20-24 16104504-7 2005 p 53 protein expression was analyzed by fluorescence immunohistochemical method (SABC-Cy3). sabc-cy3 81-89 P53 Homo sapiens 0-4 15713419-2 2005 The most potent compound, 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2,3-dihydroisoindol-1-one (NU8231), exhibited an IC50 of 5.3 +/- 0.9 microM in an ELISA assay, and induced p53-dependent gene transcription in a dose-dependent manner, in the SJSA human sarcoma cell line. 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2,3-dihydroisoindol-1-one 26-116 P53 Homo sapiens 198-201 15713419-2 2005 The most potent compound, 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2,3-dihydroisoindol-1-one (NU8231), exhibited an IC50 of 5.3 +/- 0.9 microM in an ELISA assay, and induced p53-dependent gene transcription in a dose-dependent manner, in the SJSA human sarcoma cell line. 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2,3-dihydroisoindol-1-one 118-124 P53 Homo sapiens 198-201 15546879-4 2005 Our results showed that simultaneous 5-FU and DENSPM, a spermine analogue, synergistically increased transcript levels of the polyamine catabolism enzyme spermidine/spermine N1-acetyltransferase, depleted spermine and spermidine, increased acetylated spermidine, and produced synergistic tumor cell apoptosis in both p53 wild-type and p53-null variants. Spermine 56-64 P53 Homo sapiens 317-320 15546879-4 2005 Our results showed that simultaneous 5-FU and DENSPM, a spermine analogue, synergistically increased transcript levels of the polyamine catabolism enzyme spermidine/spermine N1-acetyltransferase, depleted spermine and spermidine, increased acetylated spermidine, and produced synergistic tumor cell apoptosis in both p53 wild-type and p53-null variants. Spermine 56-64 P53 Homo sapiens 335-338 15652229-12 2005 In spite of the low rate of apoptosis, LA-12 caused increase of p53 level and cell cycle perturbations in the ovarian cancer cell lines studied. UNII-37WM0V5E17 39-44 P53 Homo sapiens 64-67 16127286-1 2005 OBJECTIVE: Since the p53 gene has been identified as a determinant of response to chemotherapy in ovarian carcinoma in previous studies, we investigated the significance of the p53 status in response to topotecan as second-line therapy. Topotecan 203-212 P53 Homo sapiens 177-180 16127286-4 2005 RESULTS: Wild-type p53 tumors responsive to first-line therapy maintained substantial responsiveness to topotecan. Topotecan 104-113 P53 Homo sapiens 19-22 16127286-7 2005 This outcome is consistent with the clinical observation that the efficacy of topotecan in the treatment of relapsed ovarian carcinoma patients is dependent on platinum sensitivity, because platinum-sensitive tumors are expected to carry wild-type p53. Topotecan 78-87 P53 Homo sapiens 248-251 15604277-0 2004 Tetrandrine induces early G1 arrest in human colon carcinoma cells by down-regulating the activity and inducing the degradation of G1-S-specific cyclin-dependent kinases and by inducing p53 and p21Cip1. tetrandrine 0-11 P53 Homo sapiens 186-189 15604277-8 2004 Third, tetrandrine increases the expression of p53 and p21(Cip1) in wild-type p53 HCT116 cells. tetrandrine 7-18 P53 Homo sapiens 47-50 15604277-8 2004 Third, tetrandrine increases the expression of p53 and p21(Cip1) in wild-type p53 HCT116 cells. tetrandrine 7-18 P53 Homo sapiens 78-81 15604277-9 2004 Collectively, these results show that tetrandrine arrests cells in G(1) by convergent mechanisms, including down-regulation of E2F1 and up-regulation of p53/p21(Cip1). tetrandrine 38-49 P53 Homo sapiens 153-156 15489892-0 2004 Inhibition of p53-mediated transcriptional responses by mithramycin A. mithramycin A 56-69 P53 Homo sapiens 14-17 15489892-1 2004 In the present work, we show that mithramycin A, a drug that is currently used for the treatment of patients with Paget"s disease of the bone as well as with several forms of cancer, is a strong activator of the tumor suppressor p53 protein in human hepatoma cells. mithramycin A 34-47 P53 Homo sapiens 229-232 15489892-2 2004 The time course of p53 activation by mithramycin A was similar to the known chemotherapeutic compound 5-fluorouracil (5-FU). mithramycin A 37-50 P53 Homo sapiens 19-22 15382140-5 2004 For example, bromodomains of Gcn5, PCAF, TAF1 and CBP are able to recognize acetyllysine residues in histones, HIV Tat, p53, c-Myb or MyoD. N-epsilon-Acetyl-L-lysine 76-88 P53 Homo sapiens 120-123 15466212-7 2004 A substantial correlation with gammaH2AX loss half-time measured over the first 4 hours was seen only when cervical cell lines were included in a larger series of p53-deficient cell lines. gammah2ax 31-40 P53 Homo sapiens 163-166 15466212-8 2004 Interestingly, p53 wild-type cell lines consistently showed faster gammaH2AX loss half-times than p53-deficient cell lines. gammah2ax 67-76 P53 Homo sapiens 15-18 15138159-0 2004 Fludarabine treatment of patients with chronic lymphocytic leukemia induces a p53-dependent gene expression response. fludarabine 0-11 P53 Homo sapiens 78-81 15138159-4 2004 Many of the fludarabine signature genes were known p53 target genes and genes involved in DNA repair. fludarabine 12-23 P53 Homo sapiens 51-54 15138159-6 2004 Using isogenic p53 wild-type and null lymphoblastoid cell lines, we confirmed that many of the fludarabine signature genes were also p53 target genes. fludarabine 95-106 P53 Homo sapiens 15-18 15138159-6 2004 Using isogenic p53 wild-type and null lymphoblastoid cell lines, we confirmed that many of the fludarabine signature genes were also p53 target genes. fludarabine 95-106 P53 Homo sapiens 133-136 15138159-7 2004 Because in vivo treatment with fludarabine induces a p53-dependent gene expression response, fludarabine treatment has the potential to select p53-mutant CLL cells, which are more drug resistant and associated with an aggressive clinical course. fludarabine 31-42 P53 Homo sapiens 53-56 15138159-7 2004 Because in vivo treatment with fludarabine induces a p53-dependent gene expression response, fludarabine treatment has the potential to select p53-mutant CLL cells, which are more drug resistant and associated with an aggressive clinical course. fludarabine 31-42 P53 Homo sapiens 143-146 15138159-7 2004 Because in vivo treatment with fludarabine induces a p53-dependent gene expression response, fludarabine treatment has the potential to select p53-mutant CLL cells, which are more drug resistant and associated with an aggressive clinical course. fludarabine 93-104 P53 Homo sapiens 53-56 15138159-7 2004 Because in vivo treatment with fludarabine induces a p53-dependent gene expression response, fludarabine treatment has the potential to select p53-mutant CLL cells, which are more drug resistant and associated with an aggressive clinical course. fludarabine 93-104 P53 Homo sapiens 143-146 15524402-6 2004 Taken together, these results revealed that safrole oxide could induce apoptosis of A549 cells and suggested that safrole oxide might perform its function by blocking cells completely at G1 phase and partly at G(2)-M phase, and also by up-regulating the expression of P53 protein. safrole oxide 44-57 P53 Homo sapiens 268-271 15524402-6 2004 Taken together, these results revealed that safrole oxide could induce apoptosis of A549 cells and suggested that safrole oxide might perform its function by blocking cells completely at G1 phase and partly at G(2)-M phase, and also by up-regulating the expression of P53 protein. safrole oxide 114-127 P53 Homo sapiens 268-271 15260130-4 2004 However, pre-treatment with FK506 and V10367 significantly prevented any increase in this ratio or p53 mRNA expression. Tacrolimus 28-33 P53 Homo sapiens 99-102 15207728-7 2004 Molecular analysis indicates that induction of p53 and p21, and suppression of pRB are associated with apoptosis induced by 5-FUdR and may partly explain the hypersensitivity of E6E7/OSE cells to low-dose 5-FUdR. Floxuridine 124-130 P53 Homo sapiens 47-50 15207728-7 2004 Molecular analysis indicates that induction of p53 and p21, and suppression of pRB are associated with apoptosis induced by 5-FUdR and may partly explain the hypersensitivity of E6E7/OSE cells to low-dose 5-FUdR. Floxuridine 205-211 P53 Homo sapiens 47-50 15252149-0 2004 Selenite-induced p53 Ser-15 phosphorylation and caspase-mediated apoptosis in LNCaP human prostate cancer cells. Selenious Acid 0-8 P53 Homo sapiens 17-20 15252149-2 2004 We and others have shown that selenite induces apoptotic DNA laddering in the p53-mutant DU145 prostate cancer cells and the p53-null HL60 leukemia cells without the cleavage of poly(ADP-ribose) polymerase (PARP; i.e., caspase-independent apoptosis), whereas selenium compounds leading to the formation of methylselenol induce caspase-mediated apoptosis in these cells. Selenious Acid 30-38 P53 Homo sapiens 78-81 15252149-2 2004 We and others have shown that selenite induces apoptotic DNA laddering in the p53-mutant DU145 prostate cancer cells and the p53-null HL60 leukemia cells without the cleavage of poly(ADP-ribose) polymerase (PARP; i.e., caspase-independent apoptosis), whereas selenium compounds leading to the formation of methylselenol induce caspase-mediated apoptosis in these cells.

Parathion 68-73 P53 Homo sapiens 129-132 15107830-7 2004 Most cells exhibited elevated levels of p53 in response to hypoxia mimetics such as deferoxamine mesylate and CoCl(2), regardless of their HIF-alpha protein expression profile. cobaltous chloride 110-117 P53 Homo sapiens 40-43 15122344-3 2004 Subsequently, we found that 2,3-DCPE could induce S-phase arrest and upregulate p21 but not p27 at a time- and dose-dependent but p53-dispensable manner in DLD-1 human colon cancer cells. 2-((3-(2,3-dichlorophenoxy)propyl)amino)ethanol 28-36 P53 Homo sapiens 130-133 18270365-6 2008 The authors identified 1 natural product, sempervirine, that inhibited MDM2 auto-ubiquitination, MDM2-mediated p53 degradation, and led to accumulation of p53 in cells. sempervirine 42-54 P53 Homo sapiens 111-114 18270365-6 2008 The authors identified 1 natural product, sempervirine, that inhibited MDM2 auto-ubiquitination, MDM2-mediated p53 degradation, and led to accumulation of p53 in cells. sempervirine 42-54 P53 Homo sapiens 155-158 18270365-7 2008 Sempervirine preferentially induced apoptosis in transformed cells expressing wild-type p53, suggesting that it could be a potential lead for anticancer therapeutics. sempervirine 0-12 P53 Homo sapiens 88-91 19009304-0 2009 Establishment of ponasterone A-inducible the wild-type p53 protein-expressing clones from HSC-1 cells, cell growth suppression by p53 expression and the suppression mechanism. ponasterone A 17-30 P53 Homo sapiens 130-133 15269478-6 2004 MATERIALS AND METHODS: p53 protein expression was evaluated on formalin-fixed paraffin-embedded sections using streptavidin biotin immunoperoxidase technique after high temperature antigen retrieval.

Chlorides 0-8 P53 Homo sapiens 99-102 19452524-8 2009 This was especially true for TP53 transversion mutations and dietary antioxidants (OR for beta-carotene 0.51 95% CI 0.27, 0.97, p trend 0.03; alpha-tocopherol 0.41 95% CI 0.20, 0.84, p trend 0.02) Beta-carotene and ibuprofen significantly altered risk of KRAS2 tumors. alpha-Tocopherol 142-158 P53 Homo sapiens 29-33 18067855-5 2008 These observations indicate that chloride ions play important roles in cell-cycle progression by regulating the expression of p21 through a p53-independent pathway in human gastric cancer cells, leading to a novel, unique therapeutic strategy for gastric cancer treatment via control of [Cl(-)](i).

Eicosapentaenoic Acid 0-21 P53 Homo sapiens 63-66 15285929-7 2004 We also observed that EPA induced transient nuclear accumulation of P53 protein that subsequently up-regulated the expression of Fas messenger RNA and protein in HepG2 cells.

Quinacrine 79-89 P53 Homo sapiens 10-14 18006756-3 2007 The genotoxic drug doxorubicin and the anti-inflammatory and antimalarial drug quinacrine, previously identified as inducers of TP53, were used to examine the nature and potential reversibility of deficient TP53 expression and function. Quinacrine 79-89 P53 Homo sapiens 128-132 18006756-7 2007 Although doxorubicin failed to induce TP53 expression or functional activity, quinacrine induced TP53 mRNA and protein expression, increased TP53 reporter activity and p21 protein expression, and induced growth inhibition in these wild-type TP53 cell lines. Quinacrine 78-88 P53 Homo sapiens 97-101 18006756-7 2007 Although doxorubicin failed to induce TP53 expression or functional activity, quinacrine induced TP53 mRNA and protein expression, increased TP53 reporter activity and p21 protein expression, and induced growth inhibition in these wild-type TP53 cell lines. Quinacrine 78-88 P53 Homo sapiens 97-101 18006756-7 2007 Although doxorubicin failed to induce TP53 expression or functional activity, quinacrine induced TP53 mRNA and protein expression, increased TP53 reporter activity and p21 protein expression, and induced growth inhibition in these wild-type TP53 cell lines.

DyeCycle Violet 12-15 P53 Homo sapiens 108-111 14676405-2 2003 Previously we reported that the accumulation of inducible nitric oxide (NO) synthase (iNOS) was induced only in human glioblastoma mutant (m) p53 cells by acute irradiation with X-rays, suggesting a suppression of iNOS induction after acute irradiation with X-rays in wtp53 cells. nitric 58-64 P53 Homo sapiens 142-145 17726646-4 2007 Fusion of the p53 nuclear export signaling sequence MFRELNEALELK to NDelta19 (NDelta19NES) abolished its apoptosis promoting properties, while overexpression of NDelta19 significantly increased the susceptibility to apoptosis induction by the proteasome inhibitor PSI and by staurosporine. ndelta19nes 78-89 P53 Homo sapiens 14-17 19373929-8 2009 The data indicate that supravital use of Ho 42, DRAQ5, and DCV induces various degrees of DDR, including activation of ATM, Chk2 and p53, which may have significant consequences on regulatory cell cycle pathways and apoptosis. DyeCycle Violet 59-62 P53 Homo sapiens 133-136 17704656-6 2007 Sublethal concentrations of BrdU evoke a DNA damage response in these cells that involves the activation of Chk1, Chk2 and p53. Bromodeoxyuridine 28-32 P53 Homo sapiens 123-126 12948852-5 2003 Treatment of cells with tetrandrine caused the upregulation of p53, downregulation of Bcl-X(L), cleavage of Bid and Bax, and release of cytochrome c, which were accompanied by activation of caspases 9, 3 and 8. tetrandrine 24-35 P53 Homo sapiens 63-66 19197159-7 2009 Binding of Cep164 to the region of exon 4 to intron 9 within p53 gene, known as a pyrimidine-rich region as well as a photoproduct formation region upon UV damage, increases 2.5-fold upon UV irradiation. pyrimidine 82-92 P53 Homo sapiens 61-64 12810654-8 2003 In these cells too, the GA analogues antagonized DDP, suggesting a role for p53 in the observed effects. geldanamycin 24-26 P53 Homo sapiens 76-79 17971903-5 2007 In p53-null PC-3 cells, prazosin induced an increase in DNA strand breaks and ATM/ATR checkpoint pathways, leading to the activation of downstream signaling cascades, including Cdc25c phosphorylation at Ser216, nuclear export of Cdc25c, and cyclin-dependent kinase (Cdk) 1 phosphorylation at Tyr15. Prazosin 24-32 P53 Homo sapiens 3-6 19018867-6 2009 RESULTS AND CONCLUSIONS: At the clinically relevant concentration of fludarabine, TP53-abnormal samples exhibited markedly higher resistance to fludarabine than the remaining CLL samples (P = 0.012); cohort with ATM deletion was not more resistant than wt cells. fludarabine 69-80 P53 Homo sapiens 82-86 17636258-5 2007 Topotecan- and paclitaxel-resistant prostate cancer lines were as sensitive to p53p-Ant-induced targeted necrosis as parental lines. Topotecan 0-9 P53 Homo sapiens 79-83 17301063-10 2007 Thus, mismatch repair-mediated enhancement of Cr(VI) cytotoxicity by Asc should promote the selection of MSI+/wt-p53 phenotype found among chromate-induced human lung cancers. Ascorbic Acid 69-72 P53 Homo sapiens 113-116 12771037-9 2003 Moreover, UVR-induced skin p53 expression, assessed immunohistochemically at 24 h post-UVR exposure, fell from a mean of 16 (SD 5) positive cells/100 epidermal cells at baseline to 8 (4) after EPA supplementation, P < 0.01. Eicosapentaenoic Acid 193-196 P53 Homo sapiens 27-30 12771037-13 2003 Reduction in this range of early markers, i.e. sunburn, UVR-induced p53 in skin and strand breaks in PBL, indicate protection by dietary EPA against acute UVR-induced genotoxicity; longer-term supplementation might reduce skin cancer in humans.

Bongkrekic Acid 97-112 P53 Homo sapiens 237-240 17204746-9 2007 Thus, disruption of p53/p90RSK-mediated NF-kappaB signaling and activation of ARE/EpRE pathways may be effective strategies to delineate mechanisms of action of BFA-induced inflammation and cell death signaling in immortalized versus normal skin systems. O(4)-benzylfolic acid 161-164 P53 Homo sapiens 20-23 19189638-6 2008 Conversely, RKO cells expressing wildtype p53, proteolytically activated caspase-8, -9, -7 and -3 and unmethylated caspase-8 were more responsive to 5-FU and selenous acid-induced apoptosis.

Selenious Acid 55-63 P53 Homo sapiens 72-75 18959823-9 2008 Taken together, these results indicate that p53 involves selenite-induced NB4 cell apoptosis by translocation to mitochondria and activation mitochondrial apoptosis pathway in a transcription-independent manner. Selenious Acid 57-65 P53 Homo sapiens 44-47 18460348-0 2008 Novel nitric oxide-donating compound (S,R)-3-phenyl-4,5-dihydro-5-isoxazole acetic acid-nitric oxide (GIT-27NO) induces p53 mediated apoptosis in human A375 melanoma cells. 3-phenyl-4,5-dihydro-5-isoxazole acetic acid 37-87 P53 Homo sapiens 120-123 11884368-6 2002 However, p53 induced profoundly different biological effects in r-VSMCs versus n-VSMCs, causing growth arrest and apoptosis in r-VSMCs only. r-vsmcs 64-71 P53 Homo sapiens 9-12 11884368-6 2002 However, p53 induced profoundly different biological effects in r-VSMCs versus n-VSMCs, causing growth arrest and apoptosis in r-VSMCs only. r-vsmcs 127-134 P53 Homo sapiens 9-12 11884368-7 2002 In addition, dominant-negative p53 promoted cell proliferation and apoptosis in r-VSMCs but not n-VSMCs. r-vsmcs 80-87 P53 Homo sapiens 31-34 17213797-3 2006 BaP 7,8-diol 9,10-epoxide (BPDE), an ultimate metabolite of BaP, attacks deoxyguanosine to form a BPDE-N2-dG adduct resulting in p53 mutations. benzylaminopurine 0-3 P53 Homo sapiens 129-132 16950207-6 2006 Combined sulindac/ATO treatment also activated p53 expression, and inhibition of p53 expression by small interfering RNA (siRNA) prevented sulindac/ATO-induced down-regulation of survivin, suggesting that survivin expression is negatively regulated by p53. Sulindac 9-17 P53 Homo sapiens 47-50 18780655-1 2008 AIM: To examine by means of immunohistochemistry the expression of the tumor suppressing gene p53 and gene p21 in cells of malignant melanoma of the uvea from formalin-paraffin material from patients, who were during the period 2000 - 2006 surgically treated due to malignant melanoma of the uvea at the Department of Ophthalmology in the University Hospital in Brno (Brunn), Czech Republic, E.U., and to correlate the results of the immunohistochemical detection with clinical signs of the tumor of each patient. Formaldehyde 159-167 P53 Homo sapiens 94-97 17201174-7 2006 The level of p53 was greatly increased, whilst PARP-1 was cleaved to 85 kDa subunits, following the treatment with xanthorrhizol at a dose-dependent manner. xanthorrhizol 115-128 P53 Homo sapiens 13-16 17201174-8 2006 These results, thereby, suggest that xanthorrhizol has antiproliferative effects on MCF-7 cells by inducing apoptosis through the modulation of bcl-2, p53 and PARP-1 protein levels. xanthorrhizol 37-50 P53 Homo sapiens 151-154 11888912-0 2002 Perifosine, a novel alkylphospholipid, induces p21(WAF1) expression in squamous carcinoma cells through a p53-independent pathway, leading to loss in cyclin-dependent kinase activity and cell cycle arrest. perifosine 0-10 P53 Homo sapiens 106-109 11888912-12 2002 These data, therefore, indicate that perifosine blocks cell cycle progression of head and neck squamous carcinoma cells at G(1)-S and G(2)-M by inducing p21(WAF1), irrespective of p53 function, and may be exploited clinically because the majority of human malignancies harbor p53 mutations. perifosine 37-47 P53 Homo sapiens 276-279 11888918-11 2002 In the latter case, > or = 80% of the PEN-induced apoptosis was dependent on the presence of wild-type p53. Penicillamine 41-44 P53 Homo sapiens 106-109 18445521-5 2008 In contrast to irinotecan, ST1968 still showed an excellent, persisting activity in models less susceptible to apoptosis induction (KB, Caski and SiHa), in which drug treatment elicited a persistent DNA damage response, as documented by phosphorylation of p53, RPA-2 and histone H2AX, resulting in delayed apoptosis and senescence. namitecan 27-33 P53 Homo sapiens 256-259 11850838-5 2002 Adenoviral delivery of p53 resulted in potent inhibition in production of proMMP-13 (by 71 to 92%) and collagenase-1 (MMP-1) (by 27 to 93%) by all cell lines in 24 h, whereas production of gelatinase-A (MMP-2) and gelatinase-B (MMP-9) was not altered. prommp-13 74-83 P53 Homo sapiens 23-26 11862321-4 2002 Cells with different states of p53 expression, either endogenously or ectopically, were exposed to hydroxyurea to induce an imbalance of cellular dNTP pools and cause replication errors. Parathion 146-150 P53 Homo sapiens 31-34 12065876-2 2002 METHODS: The expression of p53 and mdm2 was analyzed by an immunohistochemical assay in 80 formalin-fixed paraffin embedded primary tumour samples and related to the clinical response to 5-fluorouracil therapy and to the prognosis of the patients. Formaldehyde 91-99 P53 Homo sapiens 27-30 16624386-13 2006 CIZAR increased the expression of p21(waf1) which is a part of p53-independent pathway and induced reduction of telomerase activity. cizar 0-5 P53 Homo sapiens 63-66 18598164-7 2008 Up-regulation of p21(CIP1/WAF1) was found to be mediated by a p53-dependent pathway in EAPP-induced G(1)-arrested A172 cells. eapp 87-91 P53 Homo sapiens 62-65 16826403-10 2006 CONCLUSION: The AN-7 combined with doxorubicin overcame drug resistance; at least in part by the intracellularly releasable formaldehyde that augmented formation of doxorubicin-DNA adducts and butyric acid that induced histone and p53 acetylation. Formaldehyde 124-136 P53 Homo sapiens 231-234 17050670-5 2006 We show that p53 binds to a 10-bp perfect palindromic decanucleotide (GTGACGTCAC) in the ECK promoter, activates the ECK promoter, and increases the transcription of ECK. decanucleotide 54-68 P53 Homo sapiens 13-16 11696352-0 2001 Transcriptional repression of the human p53 gene by cobalt chloride mimicking hypoxia. cobaltous chloride 52-67 P53 Homo sapiens 40-43 11696352-2 2001 We herein report that the transcription of the human p53 gene was repressed by treatment with a hypoxia-mimicking concentration of cobalt chloride and alone by hypoxia-inducible factor 1alpha. cobaltous chloride 131-146 P53 Homo sapiens 53-56 17094452-8 2006 Silvestrol caused a dose-dependent decrease in p53 protein within 30 min of exposure with no p53 detectable after 6 h. Down-regulation of p53 by silvestrol was associated with down-regulation of MDM2 and not prevented by lactacystin suggesting that silvestrol-induced degradation of p53 is not mediated by the proteasome. silvestrol 0-10 P53 Homo sapiens 47-50 11710597-1 2001 PURPOSE: To establish the relationship between the number and site of p53 genomic mutations in metastatic colorectal cancer, and the response to hepatic arterial floxuridine. Floxuridine 162-173 P53 Homo sapiens 70-73 18400537-10 2008 These studies indicate that p53 specifically drives de novo ceramide synthesis by activation of a ceramide synthase that favors the synthesis of N-palmitoylsphingosine. N-palmitoylsphingosine 145-167 P53 Homo sapiens 28-31 17094452-10 2006 These data demonstrate that cytotoxicity induced by silvestrol in LNCaP cells is associated with a block in the cell cycle at the G2/M checkpoint and alterations in the expression of genes regulating apoptosis and cell cycle in a manner independent of p53. silvestrol 52-62 P53 Homo sapiens 252-255 16574813-5 2006 Moreover, the data herein clearly show that ganglioside GM3 induces p53-dependent transcriptional activity of p21(WAF1), as evidenced by the p21(WAF1) promoter-driven luciferase reporter plasmid (full-length p21(WAF1) promoter and a construct lacking the p53-binding sites). gm3 56-59 P53 Homo sapiens 255-258 18071310-10 2008 These results suggest that abrogation of G2 checkpoint by GM may play a central role in sensitizing p53-negative tumor cells to DNA-damaging and decatenation-inhibiting agents. geldanamycin 58-60 P53 Homo sapiens 100-103 16574813-8 2006 On the contrary, suppression of PTEN levels by RNA interference restores the enhanced expression of p53-dependent p21(WAF1) and p53-independent p27(kip1) through inactivating the effect of PTEN on PI-3K/AKT signaling modulated by ganglioside GM3. gm3 242-245 P53 Homo sapiens 100-103 16574813-8 2006 On the contrary, suppression of PTEN levels by RNA interference restores the enhanced expression of p53-dependent p21(WAF1) and p53-independent p27(kip1) through inactivating the effect of PTEN on PI-3K/AKT signaling modulated by ganglioside GM3. gm3 242-245 P53 Homo sapiens 128-131 21059310-4 2001 p53 genemutation was detected by polymerase chain reaction ( PCR)-single strand conformation polymorphism ( SSCP)-silver staining technique and the mutated p53 gene specimen was analysed by DNA-sequencing .

Valine 110-113 P53 Homo sapiens 95-98 11521201-4 2001 We observed that an unmodified C-terminus was required for the suppression of apoptosis by the p53 135(Ala to Val) oncogenic p53 mutant. Valine 110-113 P53 Homo sapiens 125-128 16614167-9 2006 CDC2-Y15-P was transiently elevated in arsenite-treated p53+ cells but persisted in p53- cells. arsenite 39-47 P53 Homo sapiens 56-59 16614167-10 2006 Arsenite induced p53-S15-P and p21CIP1/WAF1 only in p53+ cells. arsenite 0-8 P53 Homo sapiens 17-20 16614167-10 2006 Arsenite induced p53-S15-P and p21CIP1/WAF1 only in p53+ cells. arsenite 0-8 P53 Homo sapiens 52-55 16702812-0 2006 Octahedral Pt(IV) complex K101 induces apoptosis via ERK1/2 activation and the p53 pathway in human colon cancer cells. THIAMINE HYDROCHLORIDE 26-30 P53 Homo sapiens 79-82 18454047-0 2008 The novel platinum(IV) complex LA-12 induces p53 and p53/47 responses that differ from the related drug, cisplatin. UNII-37WM0V5E17 31-36 P53 Homo sapiens 53-56 18454047-3 2008 We tested the effects of LA-12 on the p53 response and demonstrate that LA-12 induces unique changes in the profile of gene expression compared with cisplatin and doxorubicin. UNII-37WM0V5E17 72-77 P53 Homo sapiens 38-41 16407843-3 2006 In human colon carcinoma HCT116 cells with wild-type (wt) p53, gammaH2AX reverses after camptothecin removal. gammah2ax 63-72 P53 Homo sapiens 58-61 11489357-1 2001 In a previous study we reported that methylation within the promoter region of p53 was altered in human lung A549 cells exposed to arsenite over a 2-week period in culture. arsenite 131-139 P53 Homo sapiens 79-82 18454047-4 2008 Furthermore, the ability of LA-12 to disrupt cellular proliferation is greatly enhanced by the expression of p53 and p53/47 indicating both p53-dependent and p53-independent effects of LA-12. UNII-37WM0V5E17 28-33 P53 Homo sapiens 109-112 11699407-2 2001 The effects of combining a phosphorothioate oligonucleotide OL(1) p53, which transiently down-regulates p53 levels, with an anthracycline, Idarubicin, on the growth of wild-type p53 WMN gene-expressing lymphoma cells was evaluated. Parathion 27-43 P53 Homo sapiens 104-107 18454047-4 2008 Furthermore, the ability of LA-12 to disrupt cellular proliferation is greatly enhanced by the expression of p53 and p53/47 indicating both p53-dependent and p53-independent effects of LA-12. UNII-37WM0V5E17 28-33 P53 Homo sapiens 117-120 11699407-2 2001 The effects of combining a phosphorothioate oligonucleotide OL(1) p53, which transiently down-regulates p53 levels, with an anthracycline, Idarubicin, on the growth of wild-type p53 WMN gene-expressing lymphoma cells was evaluated.

Polyethylene 101-113 P53 Homo sapiens 161-164 18454047-4 2008 Furthermore, the ability of LA-12 to disrupt cellular proliferation is greatly enhanced by the expression of p53 and p53/47 indicating both p53-dependent and p53-independent effects of LA-12. UNII-37WM0V5E17 28-33 P53 Homo sapiens 117-120 18454047-4 2008 Furthermore, the ability of LA-12 to disrupt cellular proliferation is greatly enhanced by the expression of p53 and p53/47 indicating both p53-dependent and p53-independent effects of LA-12. UNII-37WM0V5E17 28-33 P53 Homo sapiens 117-120 11406180-0 2001 Effects of arsenite on p53, p21 and cyclin D expression in normal human fibroblasts -- a possible mechanism for arsenite"s comutagenicity. arsenite 112-120 P53 Homo sapiens 23-26 11406180-3 2001 To determine whether arsenite affects signaling which might alter DNA repair, this study assesses the effect of arsenite on p53-related signal transduction pathways after ionizing radiation. arsenite 112-120 P53 Homo sapiens 124-127 11406180-4 2001 Long-term (14 day) low dose (0.1 microM) arsenite caused a modest increase in p53 expression in WI38 normal human fibroblasts, while only toxic (50 microM) concentrations increased p53 levels after short-term (18 h) exposure. arsenite 41-49 P53 Homo sapiens 78-81 11406180-8 2001 These results show that in cells treated with arsenite, p53-dependent increase in p21 expression, normally a block to cell cycle progression after DNA damage, is deficient. arsenite 46-54 P53 Homo sapiens 56-59 16700663-5 2006 An immunohistochemical method was used to investigate the expression of COX-2 and p53 proteins on formalin-fixed, paraffin-embedded tissue specimens of squamous cell carcinomas (SCC), basal cell carcinomas (BCC), Bowen"s disease (BD), actinic keratosis (AK) and porokeratosis. Formaldehyde 98-106 P53 Homo sapiens 82-85 11406180-10 2001 We suggest that the absence of normal p53 functioning, along with increased positive growth signaling in the presence of DNA damage may result in defective DNA repair and account for the comutagenic effects of arsenite. arsenite 210-218 P53 Homo sapiens 38-41 18454047-5 2008 Exposure of the human cancer cell lines H1299, A2780, BT549 and BT474 to LA-12 alters the expression of p53 and p53/47 in both a time-dependent and dose-dependent manner.

UNII-37WM0V5E17 39-44 P53 Homo sapiens 13-16 11429707-2 2001 We report here that arsenite induces GADD45alpha expression in a p53-independent fashion and that this GADD45alpha induction by arsenite is regulated by NF-kappaB and c-Jun-N-terminal kinase (JNK) oppositely. arsenite 20-28 P53 Homo sapiens 65-68 11429707-6 2001 Analysis of GADD45alpha expression in both wild-type and p53-/- fibroblasts indicated that the induction of GADD45alpha by arsenite was independent of the status of p53 protein. arsenite 123-131 P53 Homo sapiens 57-60 16288207-6 2006 Suppression of sGC activity with the specific inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) lowered cGMP content, and increased p53 protein content and induced apoptosis in three ovarian cancer cell lines, effects which were attenuated by the cGMP analog 8-Br-cGMP and by Atrial Natriuretic Factor, an activator of particulate guanylyl cyclase, which circumvent the inhibition of sGC. 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one 56-99 P53 Homo sapiens 142-145 16288207-6 2006 Suppression of sGC activity with the specific inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) lowered cGMP content, and increased p53 protein content and induced apoptosis in three ovarian cancer cell lines, effects which were attenuated by the cGMP analog 8-Br-cGMP and by Atrial Natriuretic Factor, an activator of particulate guanylyl cyclase, which circumvent the inhibition of sGC. 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one 101-104 P53 Homo sapiens 142-145 16288207-9 2006 Pretreatment with the specific p53 inhibitor pifithrin or downregulation of p53 using a specific small inhibitory RNA significantly attenuated ODQ-induced apoptosis. 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one 143-146 P53 Homo sapiens 31-34 16288207-9 2006 Pretreatment with the specific p53 inhibitor pifithrin or downregulation of p53 using a specific small inhibitory RNA significantly attenuated ODQ-induced apoptosis. 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one 143-146 P53 Homo sapiens 76-79 12578616-2 2001 The effects of exogenous wt-p53 gene on the proliferation and differentiation of K562 cells were studied by detection of cell growth curves, leukemic colony formation, cell cycle analysis and DNA fragmentation, TdT-mediated dUTP nick end labeling (TUNEL) and benzidine staining. benzidine 259-268 P53 Homo sapiens 28-31 17610029-8 2008 We conclude that selenite induces caspase-independent apoptosis in cervical carcinoma cells mostly by oxidative stress-mediated activation of p53 and p38 pathways, but other selenite-mediated effects, in particular mitochondria-specific ones, are also involved.

(2)o(3) 2-9 P53 Homo sapiens 88-91 16489034-3 2006 In the present study, we showed that selenite-induced apoptosis was superoxide mediated and p53 dependent via mitochondrial pathways. Selenious Acid 37-45 P53 Homo sapiens 92-95 18630678-10 2008 CONCLUSION: The telomerase activation and mutant P53 expression in MDA-MB-435s cells are related to HSP90 function, of which the inhibition with GA can decrease the telomerase activity and the protein expression of mutant P53, and further repress the proliferation of MDA-MB-435s cells. geldanamycin 145-147 P53 Homo sapiens 222-225 16489034-4 2006 In addition, we also showed that superoxide production by selenite was p53 dependent.

Bromodeoxyuridine 0-17 P53 Homo sapiens 26-29 11752901-6 2001 CONCLUSIONS: These data suggested that the BrdU-induced growth suppression of the cell lines examined was mainly caused by cell cycle arrest rather than cell death, and that the cell cycle arrests in the first S and G(1) phases (elicited by BrdU in the single DNA strand) and those in the second S, G(2) and G(1) phases (elicited by BrdU in the double DNA strands) were mediated by p53-dependent and -independent pathways, respectively. Bromodeoxyuridine 43-47 P53 Homo sapiens 382-385 18403247-8 2008 We found that oncogenes c-myc, c-fos and tumor suppressor genes, P53, Rb were regulated by ginsenoside Rg1, cinnamic acid, and tanshinone IIA as well. cinnamic acid 108-121 P53 Homo sapiens 65-68 11134551-7 2001 Exposure to 250 microM or 1000 microM phenytoin also elicited a relatively minor (less than 2-fold) but significant increase in p53 steady-state mRNA expression. Phenytoin 38-47 P53 Homo sapiens 128-131 16489034-9 2006 LNCaP cells treated with selenite also showed p53 translocation to mitochondria, cytochrome c release into the cytosol, and activation of caspase-9.

Quinacrine 103-113 P53 Homo sapiens 138-141 16287968-8 2005 The results demonstrate, in principle, the possibility to kill cancer cells selectively through simultaneous inhibition of NF-kappaB and activation of p53 by a single small molecule and suggest anticancer applications for the well known antimalaria drug quinacrine. Quinacrine 254-264 P53 Homo sapiens 151-154 18253895-4 2008 Based on reported evidence that paraquat increases p53 protein levels and inhibits mitochondrial function, it was hypothesized that paraquat induces cell death in dopaminergic neurons through a mechanism in which p53 and mitochondrial apoptotic pathway are linked.

Paraquat 32-40 P53 Homo sapiens 213-216 10880954-5 2000 When the responses of the tumour suppressors p53 and RB were analysed, it was found that TNF-alpha and C8-ceramide induced increased expression of p53. 2,3-N-octanoylsphingosine 103-114 P53 Homo sapiens 45-48 10880954-5 2000 When the responses of the tumour suppressors p53 and RB were analysed, it was found that TNF-alpha and C8-ceramide induced increased expression of p53. 2,3-N-octanoylsphingosine 103-114 P53 Homo sapiens 147-150 18253895-4 2008 Based on reported evidence that paraquat increases p53 protein levels and inhibits mitochondrial function, it was hypothesized that paraquat induces cell death in dopaminergic neurons through a mechanism in which p53 and mitochondrial apoptotic pathway are linked. Paraquat 132-140 P53 Homo sapiens 51-54 10880954-6 2000 Treatment with TNF-alpha or C8-ceramide lead to a significant decrease in total retinoblastoma protein (RB) content that correlated with high levels of p53. 2,3-N-octanoylsphingosine 28-39 P53 Homo sapiens 152-155 15905198-0 2005 Novel genotoxicity assays identify norethindrone to activate p53 and phosphorylate H2AX. Norethindrone 35-48 P53 Homo sapiens 61-64 18253895-4 2008 Based on reported evidence that paraquat increases p53 protein levels and inhibits mitochondrial function, it was hypothesized that paraquat induces cell death in dopaminergic neurons through a mechanism in which p53 and mitochondrial apoptotic pathway are linked. Paraquat 132-140 P53 Homo sapiens 213-216 15905198-2 2005 We applied a novel and particularly sensitive method to screen for DNA damage with special attention to double-strand breaks (DSBs) and identified norethindrone to be likely genotoxic and therefore potentially mutagenic: a p53-reporter assay served as a first, high-throughput screening method and was followed by the immunofluorescent detection of phosphorylated H2AX as a sensitive assay for the presence of DSBs. Norethindrone 147-160 P53 Homo sapiens 223-226 15905198-3 2005 Norethindrone at concentrations of 2-100 microg/ml activated p53 and phosphorylated H2AX specifically and in a dose-dependent manner. Norethindrone 0-13 P53 Homo sapiens 61-64 18253895-11 2008 These findings support the conclusion that paraquat produced apoptosis in SY5Y cells through the mitochondrial intrinsic pathway associated with p53. Paraquat 43-51 P53 Homo sapiens 145-148 18089819-9 2007 Therefore, functional p53 seems to stimulate the repair of CNU-induced cross-links and/or DSBs generated from CNU-induced lesions. 1-(2-chloroethyl)-1-nitrosourea 59-62 P53 Homo sapiens 22-25 15993080-3 2005 The introduced N at position 8 of the purine ring generally lowered CDK2 inhibitory activity of new 8-azapurines (1,2,3-triazolo[4,5-d]pyrimidines) in comparison to the model trisubstituted purines, whereas the antiproliferative potential of some derivatives remained very high, reflecting their ability to activate p53 tumor suppressor. triazolopyrimidinone 100-112 P53 Homo sapiens 316-319 16109309-8 2005 The peroxide-resistant cells are diploid rather than aneuploid, show fundamental changes in the cytoskeletal cellular structure, suggesting less rigid more flexible cells, express a new lower molecular mass of p53, a key stress protein responder involved in adaptation, and finally have an immunochemical modification in alphaA-crystallin, a small heat-shock protein. Peroxides 4-12 P53 Homo sapiens 210-213 10850547-2 2000 A novel polymerase chain reaction (PCR) approach for the analysis of the entire p53 coding and splice site regions from microdissected, formalin-fixed, paraffin-embedded tumor tissues has been developed which allows multiple genetic analyses to be performed from one primary amplification reaction. Formaldehyde 136-144 P53 Homo sapiens 80-83 18089819-9 2007 Therefore, functional p53 seems to stimulate the repair of CNU-induced cross-links and/or DSBs generated from CNU-induced lesions. 1-(2-chloroethyl)-1-nitrosourea 110-113 P53 Homo sapiens 22-25 10874665-6 2000 Mdm2 and p53 were demonstrated by immunohistology on formalin-fixed and paraffin-embedded tumor tissue. Formaldehyde 53-61 P53 Homo sapiens 9-12 17906315-8 2007 In addition, the expression of mutant p53 increased in parallel with comet scores, and the maximal expression of mutant p53 was observed at 4 microM arsenite. arsenite 149-157 P53 Homo sapiens 38-41 10897337-3 2000 This is a highly selective approach, whereby immunostained sections of formalin fixed, paraffin wax embedded tissue are exposed to ultraviolet irradiation to damage the DNA in p53 negative cells. Formaldehyde 71-79 P53 Homo sapiens 176-179 15946692-3 2005 This study was undertaken to dissect the molecular mechanism underlying sulindac-induced apoptosis in human colon cancer cell line HT-29 (mutant p53), focusing on nuclear translocation of AIF, DFF and endonuclease G. Sulindac 72-80 P53 Homo sapiens 145-148 15950406-0 2005 Effects on protein and mRNA expression levels of p53 induced by fluoride in human embryonic hepatocytes. Fluorides 64-72 P53 Homo sapiens 49-52 10815759-2 2000 Therefore, we investigated the utility of new heterodinucleoside phosphate dimers of 5-fluorodeoxyuridine (5-FdUrd) in p53-mutated and androgen-independent DU-145 human prostate tumour cells. Floxuridine 85-105 P53 Homo sapiens 119-122 17906315-8 2007 In addition, the expression of mutant p53 increased in parallel with comet scores, and the maximal expression of mutant p53 was observed at 4 microM arsenite. arsenite 149-157 P53 Homo sapiens 120-123 10815759-2 2000 Therefore, we investigated the utility of new heterodinucleoside phosphate dimers of 5-fluorodeoxyuridine (5-FdUrd) in p53-mutated and androgen-independent DU-145 human prostate tumour cells. Floxuridine 107-114 P53 Homo sapiens 119-122 15950406-1 2005 We investigated the effects of protein and mRNA expression levels on p53 induced by fluoride in human embryo hepatocyte L-02 cells. Fluorides 84-92 P53 Homo sapiens 69-72 15950406-2 2005 The protein and mRNA levels of p53 in L-02 cells were measured after in vitro cultured L-02 was exposed to sodium fluoride at different doses (40, 80, and 160 microg/ml) for 24 h. The results showed that the cell survival rate of L-02 cells in the high dose fluoride group was significantly lower than that of the control group. Fluorides 114-122 P53 Homo sapiens 31-34 15950406-3 2005 The protein expression levels of p53 in the middle and high dose fluoride group were significantly higher than in the control group and elevated with increasing fluoride concentration. Fluorides 65-73 P53 Homo sapiens 33-36 15950406-3 2005 The protein expression levels of p53 in the middle and high dose fluoride group were significantly higher than in the control group and elevated with increasing fluoride concentration. Fluorides 161-169 P53 Homo sapiens 33-36 15950406-4 2005 The mRNA expression levels of p53 in the fluoride groups were markedly higher than in the control group. Fluorides 41-49 P53 Homo sapiens 30-33 15950406-5 2005 The mRNA expression level of p53 in the high dose fluoride group was however lower compared to the middle dose fluoride group, but similar to the low dose fluoride group. Fluorides 50-58 P53 Homo sapiens 29-32 10799338-6 2000 During the same time period lower concentrations of DBC (<10 microM) induced the formation of DBC-DNA adducts and increased p53 protein levels followed by apoptotic cell death. 7H-dibenzo(c,g)carbazole 52-55 P53 Homo sapiens 127-130 15950406-5 2005 The mRNA expression level of p53 in the high dose fluoride group was however lower compared to the middle dose fluoride group, but similar to the low dose fluoride group. Fluorides 111-119 P53 Homo sapiens 29-32 10799338-7 2000 However, increasing the concentration of DBC to 80 microM led to lower DNA adduct and p53 protein levels. 7H-dibenzo(c,g)carbazole 41-44 P53 Homo sapiens 86-89 17906315-11 2007 This study provides us with knowledge of the relationship between p53 and COX-2 over-expression in arsenite-treated urothelial cells and suggests a potential therapeutic role of COX-2 inhibitors in human urothelial malignancies. arsenite 99-107 P53 Homo sapiens 66-69 10786699-6 2000 1alpha,25-Dihydroxyvitamin D3 and EB1089 induced p53-independent apoptosis in adenoma and carcinoma cell lines in a dose-dependent manner between 10(-10) and 10(-6) M. EB1089, as well as inducing apoptosis, increased the proportion of cells in the G1 phase, particularly in the adenoma cell lines. seocalcitol 34-40 P53 Homo sapiens 49-52 15950406-5 2005 The mRNA expression level of p53 in the high dose fluoride group was however lower compared to the middle dose fluoride group, but similar to the low dose fluoride group. Fluorides 111-119 P53 Homo sapiens 29-32 15950406-6 2005 These finding suggest that fluoride can decrease the L-02 cells survival rate and induce protein and mRNA expressions of p53; however, there is no consistency between the protein expression level of p53 and the mRNA expression level. Fluorides 27-35 P53 Homo sapiens 121-124 17624594-8 2007 Western blot analyses showed that while pretreatment of TEA and Tet produced an increase in expressions of p53, p21, and Bax, pretreatment of these two agents led to a decrease in expressions of heat shock protein (hsp)90alpha, hsp90beta, and hsp70. tetrandrine 64-67 P53 Homo sapiens 107-110 10751531-3 2000 Silver staining PCR-SSCP method was used to detect mutations in exons 5, 6, 7, 8 of p53 gene and MSI at 4 loci on chromosomes 2, 5, 17 in the 73 paraffin-embedded biopsy specimens, and the relationship between them was studied further.

Formaldehyde 255-263 P53 Homo sapiens 179-182 15716589-1 2005 Recent studies have shown that an endogenous lipoperoxidation product, 9-hydroxystearic acid (9-HSA), acts in colon carcinoma cells (HT29) as a growth inhibitor by inducing p21(WAF1) in an immediate-early, p53-independent manner and that p21(WAF1) is required for 9-HSA-mediated growth arrest in HT29 cells. 9-hydroxystearic acid 71-92 P53 Homo sapiens 206-209 15716589-1 2005 Recent studies have shown that an endogenous lipoperoxidation product, 9-hydroxystearic acid (9-HSA), acts in colon carcinoma cells (HT29) as a growth inhibitor by inducing p21(WAF1) in an immediate-early, p53-independent manner and that p21(WAF1) is required for 9-HSA-mediated growth arrest in HT29 cells. 9-hydroxystearic acid 94-99 P53 Homo sapiens 206-209 15904897-8 2005 Our results also show that preincubation of HepG2 cells with vitamin C decreased the expression of p53 and bax and inhibited the release of cytochrome c, activation of downstream caspase and the cleavage of poly(ADP-ribose) polymerase, thus inhibiting the apoptosis inducing effect of 6ME. Ascorbic Acid 61-70 P53 Homo sapiens 99-102 17666403-4 2007 In cells under elevated temperatures that contained a higher level of p53 mutant phenotype, CHIP restored the native-like conformation of p53 in the presence of geldanamycin, whereas CHIP-small interfering RNA considerably increased the mutant form. geldanamycin 161-173 P53 Homo sapiens 138-141 15625077-8 2005 Thus, in HepG2 cells pravastatin and simvastatin pretreatment attenuated the p53 response to DNA damage induced by 5-fluorouracil and benzo(a)pyrene. Simvastatin 37-48 P53 Homo sapiens 77-80 10690553-7 2000 This change resulted in a Val to Phe substitution and was associated with a constitutive production of high levels of p53, which was inactive as a transcriptional activator of bax and p21.

Topotecan 22-31 P53 Homo sapiens 122-125 15648263-12 2004 Evidence also supports a proapoptotic role of the JNKs signaling pathway in vivo and clearly indicates that JNKs are required for phosphorylation of c-Jun, activation of p53, and subsequent apoptosis induced by polycarpines. polycarpine 211-223 P53 Homo sapiens 170-173 15450952-6 2004 Interestingly, 6-hydroxymelatonin strongly damaged G and C of the 5"-ACG-3" sequence complementary to codon 273 of the p53 gene. 6-hydroxymelatonin 15-33 P53 Homo sapiens 119-122 20535395-7 2007 Further western blot analysis showed that ascorbic acid treatment decreased levels of p53, phospho-p53 at ser 15, and p21, indicating that ascorbic acid relieved senescence-related G1 arrest.

Parathion 26-42 P53 Homo sapiens 208-211 17268519-4 2007 Conversely, cells with defects in the HSP90/nuclear factor-kappa B pathway expressing wild-type p53 are more resistant to geldanamycin, but still sensitive to nutlin-3. geldanamycin 122-134 P53 Homo sapiens 96-99 9865315-0 1998 In vitro transcription and translation of the tumour suppressor protein P53: qualitative and quantitative effects of FK506 and rapamycin.

N(alpha)-acetyllysine 17-30 P53 Homo sapiens 58-61 14759370-3 2004 This bromodomain/acetyl-lysine binding is responsible for p53 acetylation-dependent coactivator recruitment after DNA damage, a step essential for p53-induced transcriptional activation of the cyclin-dependent kinase inhibitor p21 in G1 cell cycle arrest. N(alpha)-acetyllysine 17-30 P53 Homo sapiens 147-150 17213797-3 2006 BaP 7,8-diol 9,10-epoxide (BPDE), an ultimate metabolite of BaP, attacks deoxyguanosine to form a BPDE-N2-dG adduct resulting in p53 mutations. benzylaminopurine 60-63 P53 Homo sapiens 129-132 14639618-12 2004 For example, of the 4 lines, the p53wt transfectant was the most resistant to topotecan and the 143mut was the most resistant to carboplatin. Topotecan 78-87 P53 Homo sapiens 33-36 16645841-6 2006 We found that this arsenite-induced G2/M phase arrest was accompanied by accumulation and/or phosphorylation of checkpoint-related molecules, including p53, Cdc25B, Cdc25C, and securin. arsenite 19-27 P53 Homo sapiens 152-155 12959929-2 2004 Although H2O2 and other peroxides have been shown to induce ataxia telangiectasia-mutated (ATM)-dependent p53 phosphorylation in response to DNA damage, the signal transduction mechanisms in response to hyperoxia are currently unknown. Peroxides 24-33 P53 Homo sapiens 106-109 16645841-8 2006 Our data suggest that the DNA damage responsive kinases ATM (ataxia-telangiectasia mutated) and ATR (ATM and Rad3-related) play critical roles in arsenite-induced G2/M phase arrest in aortic endothelial cells possibly via regulation of checkpoint-related signaling molecules including p53, Cdc25B, Cdc25C, and securin. arsenite 146-154 P53 Homo sapiens 285-288 17066513-0 2006 [6]-Gingerol induces cell cycle arrest and cell death of mutant p53-expressing pancreatic cancer cells. gingerol 4-12 P53 Homo sapiens 64-67 14695607-0 2004 A tetraguanidinium ligand binds to the surface of the tetramerization domain of protein P53. tetraguanidinium 2-18 P53 Homo sapiens 88-91 17066513-3 2006 The purpose of this study was to investigate the action of [6]-gingerol on two human pancreatic cancer cell lines, HPAC expressing wild- type (wt) p53 and BxPC-3 expressing mutated p53. gingerol 59-71 P53 Homo sapiens 181-184 15162845-0 2004 The involvement of p53 in paraquat-induced apoptosis in human lung epithelial-like cells. Paraquat 26-34 P53 Homo sapiens 19-22 17066513-7 2006 p53 expression was decreased by [6]-gingerol treatment in both cell lines suggesting that the induction of Cyclin-dependent kinase inhibitor, p21cip1, was p53-independent. gingerol 36-44 P53 Homo sapiens 0-3 15162845-1 2004 To investigate the possible role of p53 in the progression of paraquat-induced apoptosis, the authors used two cell lines that were wild-type p53-expressing human lung epithelial-like cell line (L132) and a p53-deficient human promyelocytic leukemia cell line (U937) and explored the linkage between p53, DNA damage, and apoptosis. Paraquat 62-70 P53 Homo sapiens 36-39 17066513-8 2006 [6]-Gingerol induced mostly apoptotic death in the mutant p53-expressing cells, while no signs of early apoptosis were detected in wild type p53-expressing cells and this was related to the increased phosphorylation of AKT. gingerol 4-12 P53 Homo sapiens 58-61 15162845-2 2004 Following paraquat exposure to L132 cells, the percentage of S-phase cells decreased significantly and the expression of p53 protein increased, suggesting that entry into S phase from G1 phase was blocked. Paraquat 10-18 P53 Homo sapiens 121-124 15162845-5 2004 These results suggest that paraquat-induced DNA damage caused G1 arrest and apoptosis only in L132 cells, and that p53 protein accumulation is required for the induction of apoptosis by paraquat. Paraquat 186-194 P53 Homo sapiens 115-118 17066513-9 2006 These results suggest that [6]-gingerol can circumvent the resistance of mutant p53- expressing cells towards chemotherapy by inducing apoptotic cell death while it exerts cytostatic effect on wild type p53- expressing cells by inducing temporal growth arrest. gingerol 27-39 P53 Homo sapiens 80-83 17066513-9 2006 These results suggest that [6]-gingerol can circumvent the resistance of mutant p53- expressing cells towards chemotherapy by inducing apoptotic cell death while it exerts cytostatic effect on wild type p53- expressing cells by inducing temporal growth arrest. gingerol 27-39 P53 Homo sapiens 203-206 14669279-9 2003 Positivity for Ki-67 and p53 was seen predominantly in the epithelium of inclusion cysts and deep invaginations, including those areas that had been identified as hyperplastic or dysplastic on routine hematoxylin and eosin-stained sections. Hematoxylin 201-212 P53 Homo sapiens 25-28 16966095-0 2006 Exit from arsenite-induced mitotic arrest is p53 dependent. arsenite 10-18 P53 Homo sapiens 45-48 14695179-6 2003 Here we show that both authentic peroxynitrite and SIN-1 (3-morpholinosydnonimine hydrochloride), a molecule that decomposes into NO and to form peroxynitrite, can inhibit wild-type p53 function in malignant glioma cells. linsidomine 58-95 P53 Homo sapiens 182-185 14623330-0 2003 Involvement of p53 in alpha4beta1 integrin-mediated resistance of B-CLL cells to fludarabine. fludarabine 81-92 P53 Homo sapiens 15-18 14623330-4 2003 Parallel to this different viability, fludarabine increased p53 expression on pLys-cultured cells and this increase was significantly reduced (P<or=0.05) on cells cultured on H/89. fludarabine 38-49 P53 Homo sapiens 60-63 16966095-2 2006 Using a model cell line in which p53 expression is regulated exogenously in a tetracycline-off system (TR9-7 cells) , our laboratory has shown that arsenite disrupts mitosis and that p53-deficient cells [p53(-)], in contrast to p53-expressing cells [p53(+)], display greater sensitivity to arsenite-induced mitotic arrest and apoptosis. arsenite 148-156 P53 Homo sapiens 33-36 16966095-3 2006 OBJECTIVE: Our goal was to examine the role p53 plays in protecting cells from arsenite-induced mitotic arrest. arsenite 79-87 P53 Homo sapiens 44-47 16966095-5 2006 RESULTS: Mitotic index analysis demonstrated that arsenite treatment delayed exit from G2 in p53(+) and p53(-) cells. arsenite 50-58 P53 Homo sapiens 93-96 16966095-5 2006 RESULTS: Mitotic index analysis demonstrated that arsenite treatment delayed exit from G2 in p53(+) and p53(-) cells. arsenite 50-58 P53 Homo sapiens 104-107 14981925-7 2003 Apoptosis induced by CAPE or CAO is associated with increased expression of p53, p21 and c-Jun. cao 29-32 P53 Homo sapiens 76-79 16966095-6 2006 Arsenite-treated p53(+) cells exited mitosis normally, whereas p53(-) cells exited mitosis with delayed kinetics. arsenite 0-8 P53 Homo sapiens 17-20 16966095-7 2006 Microarray analysis performed on mRNAs of cells exposed to arsenite for 0 and 3 hr after release from G2 phase synchrony showed that arsenite induced inhibitor of DNA binding-1 (ID1) differentially in p53(+) and p53(-) cells. arsenite 59-67 P53 Homo sapiens 201-204 16966095-7 2006 Microarray analysis performed on mRNAs of cells exposed to arsenite for 0 and 3 hr after release from G2 phase synchrony showed that arsenite induced inhibitor of DNA binding-1 (ID1) differentially in p53(+) and p53(-) cells. arsenite 59-67 P53 Homo sapiens 212-215 16966095-7 2006 Microarray analysis performed on mRNAs of cells exposed to arsenite for 0 and 3 hr after release from G2 phase synchrony showed that arsenite induced inhibitor of DNA binding-1 (ID1) differentially in p53(+) and p53(-) cells. arsenite 133-141 P53 Homo sapiens 201-204 12907684-5 2003 CD also suppressed activation of downstream signaling of p38 kinase and PKC, such as NF-kappaB activation, p53 accumulation, and caspase-3 activation, which are necessary for NO-induced apoptosis. Cytochalasin D 0-2 P53 Homo sapiens 107-110 16966095-7 2006 Microarray analysis performed on mRNAs of cells exposed to arsenite for 0 and 3 hr after release from G2 phase synchrony showed that arsenite induced inhibitor of DNA binding-1 (ID1) differentially in p53(+) and p53(-) cells. arsenite 133-141 P53 Homo sapiens 212-215 16966095-9 2006 CONCLUSIONS: p53 promotes mitotic exit and leads to more extensive ID1 induction by arsenite. arsenite 84-92 P53 Homo sapiens 13-16 16966095-11 2006 ID1 may play a role in the survival of arsenite-treated p53(+) cells and contribute to arsenic carcinogenicity. arsenite 39-47 P53 Homo sapiens 56-59 16865270-2 2006 We treated a human gastric carcinoma cell line, MKN-1 (mutant P53), with 500 microM CoCl(2). cobaltous chloride 84-91 P53 Homo sapiens 62-65 12912974-0 2003 Activation of a p53-mediated apoptotic pathway in quiescent lymphocytes after the inhibition of DNA repair by fludarabine. fludarabine 110-121 P53 Homo sapiens 16-19 16543464-7 2006 Combination treatment of Nutlin-3a and fludarabine synergistically increased p53 levels, and induced conformational change of Bax and apoptosis in wild-type p53 cells but not in cells with mutant p53. fludarabine 39-50 P53 Homo sapiens 77-80 12912974-11 2003 CONCLUSIONS: These results suggest that inhibition of UV-induced DNA repair by F-ara-A is critical for cytotoxicity and that induction of apoptosis may be conducted by a p53-mediated signaling mechanism to the Fas death pathway. fludarabine 79-86 P53 Homo sapiens 170-173 12859744-5 2003 Formalin-fixed, paraffin-embedded archival tissue from these cases was immunostained for p53 and used for DNA extraction for the analysis of p53 mutations by polymerase chain reaction and single-strand conformation polymorphism. Formaldehyde 0-8 P53 Homo sapiens 89-92 16543464-7 2006 Combination treatment of Nutlin-3a and fludarabine synergistically increased p53 levels, and induced conformational change of Bax and apoptosis in wild-type p53 cells but not in cells with mutant p53. fludarabine 39-50 P53 Homo sapiens 157-160 16543464-7 2006 Combination treatment of Nutlin-3a and fludarabine synergistically increased p53 levels, and induced conformational change of Bax and apoptosis in wild-type p53 cells but not in cells with mutant p53. fludarabine 39-50 P53 Homo sapiens 157-160 16928824-7 2006 A specific inhibitor of COX-2, NS398, and small interfering RNA knockdown of COX-2 were associated with reduced p53 phosphorylation and consequent decrease in p53-dependent apoptosis in resveratrol-treated cells. N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide 31-36 P53 Homo sapiens 112-115 12843186-8 2003 In the FTC-133 cell line, geldanamycin treatment decreased clonogenicity by 21% at a concentration of 50 nM; geldanamycin induced apoptosis and down-regulated c-Raf-1, mutant p53, and epidermal growth factor (EGF) receptor expression; geldanamycin inhibited EGF-stimulated invasion. geldanamycin 26-38 P53 Homo sapiens 175-178 16928824-7 2006 A specific inhibitor of COX-2, NS398, and small interfering RNA knockdown of COX-2 were associated with reduced p53 phosphorylation and consequent decrease in p53-dependent apoptosis in resveratrol-treated cells. N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide 31-36 P53 Homo sapiens 159-162 12843186-8 2003 In the FTC-133 cell line, geldanamycin treatment decreased clonogenicity by 21% at a concentration of 50 nM; geldanamycin induced apoptosis and down-regulated c-Raf-1, mutant p53, and epidermal growth factor (EGF) receptor expression; geldanamycin inhibited EGF-stimulated invasion. geldanamycin 109-121 P53 Homo sapiens 175-178 12843186-8 2003 In the FTC-133 cell line, geldanamycin treatment decreased clonogenicity by 21% at a concentration of 50 nM; geldanamycin induced apoptosis and down-regulated c-Raf-1, mutant p53, and epidermal growth factor (EGF) receptor expression; geldanamycin inhibited EGF-stimulated invasion. geldanamycin 109-121 P53 Homo sapiens 175-178 16364413-12 2006 Overall, LA-12 but not its reduced Pt(II) counterpart LA-9 is the compound effective in p53 null human ovarian cancer cells and it is able to overcome intrinsic cisplatin resistance in these cells. UNII-37WM0V5E17 9-14 P53 Homo sapiens 88-91 12823592-10 2003 Alimentary history documented that patients with a p53 over-expression had a lower intake of total calories, monounsaturated fatty acids, vitamin C and riboflavin. Fatty Acids, Monounsaturated 109-136 P53 Homo sapiens 51-54 12823592-10 2003 Alimentary history documented that patients with a p53 over-expression had a lower intake of total calories, monounsaturated fatty acids, vitamin C and riboflavin. Ascorbic Acid 138-147 P53 Homo sapiens 51-54 16891474-6 2006 Selenite induced a rapid generation of superoxide and p53 Ser(15) phosphorylation and increased Bax abundance and translocation into the mitochondria. Selenious Acid 0-8 P53 Homo sapiens 54-57 12787880-2 2003 Cells were stably transfected with a plasmid containing a chimeric DNA construct encoding a temperature-sensitive p53 variant (135(ala-->val)), which transactivates at 32 degrees but is non-functional at 37 degrees. Valine 140-143 P53 Homo sapiens 114-117 16891474-8 2006 Inactivating p53 with a dominant-negative mutant abolished apoptosis without affecting superoxide generation, whereas a superoxide dismutase mimetic agent blocked p53 activation, Bax translocation to mitochondria, cytochrome c release, and apoptosis induced by selenite/TRAIL. Selenious Acid 261-269 P53 Homo sapiens 13-16 12781329-7 2003 p27(Kip) and p21(Cip), inhibitors of cyclin/CDK complexes in G1-phase, were gradually increased after 5GG treatment in a time-dependent manner and the induction of p21(Cip) was correlated with an increase in p53 levels. pentagalloylglucose 102-105 P53 Homo sapiens 208-211 16891474-10 2006 Taken together, the results indicate that selenite induces a rapid superoxide burst and p53 activation, leading to Bax up-regulation and translocation into mitochondria, which restores the cross-talk with stalled TRAIL signaling for a synergistic caspase-9/3 cascade-mediated apoptosis execution. Selenious Acid 42-50 P53 Homo sapiens 88-91 16426753-6 2006 The inhibition of apoptosis is mediated through diazoxide"s ability to reduce p53 expression. Diazoxide 48-57 P53 Homo sapiens 78-81 12782583-1 2003 To uncover transcriptional stress responses related to p53, we used cDNA microarrays (National Cancer Institute Oncochips comprising 6500 different genes) to characterize the gene expression profiles of wild-type p53 HCT-116 cells and an isogenic p53 knockout counterpart after treatment with topotecan, a specific topoisomerase I inhibitor. Topotecan 293-302 P53 Homo sapiens 55-58 12782583-5 2003 Approximately 10% of the transcripts were up- or down-regulated in response to topotecan in the p53+/+ cells, whereas only 1% of the transcripts changed in the p53-/- cells, indicating that p53 has a broad effect on the transcriptional response to this stress. Topotecan 79-88 P53 Homo sapiens 96-99 16426753-7 2006 On the other hand, tolbutamide, a KATP channels antagonist which blocks the cellular sulphonylureas receptor, significantly increases p53 expression and apoptosis under hypoxic/anoxic conditions. Tolbutamide 19-30 P53 Homo sapiens 134-137 16426753-8 2006 Trichostatin (TSA), a p53 inhibitor, can block the effects of tolbutamide, lending further support for a role of p53 in mediating this process. Tolbutamide 62-73 P53 Homo sapiens 22-25 12945745-0 2003 Increased p53 levels without caspase-3 activity and change of cell viability in 6-hydroxydopamine-treated CV1-P cells. Oxidopamine 80-97 P53 Homo sapiens 10-13 16426753-8 2006 Trichostatin (TSA), a p53 inhibitor, can block the effects of tolbutamide, lending further support for a role of p53 in mediating this process. Tolbutamide 62-73 P53 Homo sapiens 113-116 12945745-4 2003 Interestingly, in the fibroblasts at the low 6-OHDA concentrations, p53 remained high during the whole experiment, and there was neither significant caspase-3 activity nor cell death. Oxidopamine 45-51 P53 Homo sapiens 68-71 16545693-6 2006 N-OH-ABA induced DNA damage at cytosine and guanine residues of ACG sequence complementary to codon 273, a well-known hot spot of the p53 gene. N-hydroxy-3-aminobenzanthrone 0-8 P53 Homo sapiens 134-137 12945745-7 2003 In contrast to some earlier reports, we have shown that the actual 6-OHDA sensitivity of nonneuronal cells may be equal or even higher than that in neuronal cells if the enhancement of p53 levels is used as a criterion for the response. Oxidopamine 67-73 P53 Homo sapiens 185-188 16251206-0 2006 Sequence specificity of Cr(III)-DNA adduct formation in the p53 gene: NGG sequences are preferential adduct-forming sites. tris(1,10-phenanthroline)chromium(III) chloride 24-31 P53 Homo sapiens 60-63 12771391-0 2003 DNA-protein crosslinks and p53 protein expression in relation to occupational exposure to formaldehyde. Formaldehyde 90-102 P53 Homo sapiens 27-30 12750285-3 2003 Colocalization was observed with the phosphoserine-15 form of p53 at presumed DNA processing sites after the induction of DNA breaks. Phosphoserine 37-50 P53 Homo sapiens 62-65 16251206-7 2006 We have found that the sequence specificities of Cr(III)-DNA and Cr(III)-histidine-DNA adducts in the p53 gene sequence are identical and that both types of adducts are preferentially formed at -NGG- sequences, including codons 245, 248 and 249, the mutational hotspots in human lung cancer. tris(1,10-phenanthroline)chromium(III) chloride 49-56 P53 Homo sapiens 102-105 16251206-7 2006 We have found that the sequence specificities of Cr(III)-DNA and Cr(III)-histidine-DNA adducts in the p53 gene sequence are identical and that both types of adducts are preferentially formed at -NGG- sequences, including codons 245, 248 and 249, the mutational hotspots in human lung cancer. tris(1,10-phenanthroline)chromium(III) chloride 65-72 P53 Homo sapiens 102-105 16251206-9 2006 Therefore, these results suggest that Cr(III)-DNA adduct formation contributes to the p53 gene mutations in lung carcinogenesis. tris(1,10-phenanthroline)chromium(III) chloride 38-45 P53 Homo sapiens 86-89 12642506-11 2003 Treatment with a beta1-integrin-blocking antibody or integrin signaling inhibitor cytochalasin B but not growth factor receptor inhibitor suramin abrogated both stretch-induced phosphorylation of p38 MAPK and p53 expression. Cytochalasin B 82-96 P53 Homo sapiens 209-212 16300733-6 2006 Blocking of the p53 CTDBS by a monoclonal antibody Bp53-10.1 resulted in abolishment of the isolated CTD binding to the cisPt-DNA. ctdbs 20-25 P53 Homo sapiens 16-19 12642506-12 2003 Akin to the inhibition of p38 MAPK-p53 signaling, pretreatment with a beta1-integrin-blocking antibody or cytochalasin B but not suramin inhibited stretch-induced apoptosis on collagen plates. Cytochalasin B 106-120 P53 Homo sapiens 35-38 16405733-11 2006 To this end, tacrolimus has been shown to have an impact on cancer signalling pathways such as the MAPK and the p53 pathway. Tacrolimus 13-23 P53 Homo sapiens 112-115 12628922-4 2003 Whereas levels of p53, phosphoserine-15 p53, p21, ARF and Bcl-X(L) were increased in response to exogenous overexpression of activated DDR1, dominant-negative DDR1 inhibited irradiation-induced MAPK activation and p53, phosphoserine-15 p53, as well as induced p21 and DDR1 levels, suggesting that DDR1 functions in a feedforward loop to increase p53 levels and at least some of its effectors. Phosphoserine 23-36 P53 Homo sapiens 40-43 12628922-4 2003 Whereas levels of p53, phosphoserine-15 p53, p21, ARF and Bcl-X(L) were increased in response to exogenous overexpression of activated DDR1, dominant-negative DDR1 inhibited irradiation-induced MAPK activation and p53, phosphoserine-15 p53, as well as induced p21 and DDR1 levels, suggesting that DDR1 functions in a feedforward loop to increase p53 levels and at least some of its effectors. Phosphoserine 23-36 P53 Homo sapiens 40-43 12628922-4 2003 Whereas levels of p53, phosphoserine-15 p53, p21, ARF and Bcl-X(L) were increased in response to exogenous overexpression of activated DDR1, dominant-negative DDR1 inhibited irradiation-induced MAPK activation and p53, phosphoserine-15 p53, as well as induced p21 and DDR1 levels, suggesting that DDR1 functions in a feedforward loop to increase p53 levels and at least some of its effectors. Phosphoserine 23-36 P53 Homo sapiens 40-43 12628922-4 2003 Whereas levels of p53, phosphoserine-15 p53, p21, ARF and Bcl-X(L) were increased in response to exogenous overexpression of activated DDR1, dominant-negative DDR1 inhibited irradiation-induced MAPK activation and p53, phosphoserine-15 p53, as well as induced p21 and DDR1 levels, suggesting that DDR1 functions in a feedforward loop to increase p53 levels and at least some of its effectors. Phosphoserine 23-36 P53 Homo sapiens 40-43 12424231-1 2003 Tumor suppressor p53 exhibits an enigmatic phenotype in cells exposed to electrophilic, cyclopentenone prostaglandins of the A and J series. cyclopentenone prostaglandins 88-117 P53 Homo sapiens 17-20 12473386-0 2003 Influence of p53 and p21(WAF1) expression on sensitivity of cancer cells to cladribine. Cladribine 76-86 P53 Homo sapiens 13-16 16426974-4 2006 Structural characterization shows that these chemicals inhibit CBP/p53 association by binding to the acetyl-lysine binding site of the bromodomain. N(alpha)-acetyllysine 101-114 P53 Homo sapiens 67-70 12759546-6 2003 Since p53 expression was not modified after BFA exposure, BFA-induced apoptosis may follow a p53-independent pathway, as already reported. Brefeldin A 58-61 P53 Homo sapiens 93-96 16702019-5 2006 To understand the possible mechanism of safrole oxide acting, we first examined the phosphorylation of Akt and the activity of nitric oxide synthase (NOS); secondly, we analyzed the expressions and distributions of Fas and P53; then we measured the activity of phosphatidylcholine specific phospholipase C (PC-PLC) in the VECs treated with and without safrole oxide. safrole oxide 40-53 P53 Homo sapiens 223-226 12411481-6 2002 Also, a selective Cox-2 inhibitor, NS-398, significantly enhanced genotoxic stress-induced apoptosis in several types of p53+/+ normal human cells, through a caspase-dependent pathway. N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide 35-41 P53 Homo sapiens 121-124 16702019-9 2006 The data suggested that safrole oxide effectively inhibited angiogenesis and triggered VEC apoptosis in the presence of FGF-2 and serum, and it might perform its functions by suppressing Akt/NOS signal pathway, upregulating the expressions of Fas and P53 and modifying the distributing pattern of Fas in VEC. safrole oxide 24-37 P53 Homo sapiens 251-254 17120736-6 2006 It is concluded that MDM2 specific antisense oligonucletides can inhibit the expression of MDM2, induce the expression of P53 and increase the apoptosis of leukemia cells after chemotherapy. oligonucletides 45-60 P53 Homo sapiens 122-125 17065086-1 2006 Previously, we have found that activation of deoxycytidine kinase elicited by various DNA-damaging chemical agents could be prevented by BAPTA-AM, a cell-permeable calcium chelator or by pifithrin-alpha, a pharmacological inhibitor of p53. 1,2-bis(2-aminophenoxy)ethane N,N,N',N'-tetraacetic acid acetoxymethyl ester 137-145 P53 Homo sapiens 235-238 12208600-3 2002 The reduction of Cr(VI) to Cr(III) results in the formation of reactive intermediates that together with oxidative stress oxidative tissue damage and a cascade of cellular events including modulation of apoptosis regulatory gene p53, contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. tris(1,10-phenanthroline)chromium(III) chloride 27-34 P53 Homo sapiens 229-232 16375215-4 2005 Immunostaining for p53 protein was performed on formalin-fixed, paraffin-embedded tissue sections, using the alkaline phosphatase antialkaline phosphatase (APAAP) method. Formaldehyde 48-56 P53 Homo sapiens 19-22 12359050-5 2002 Sequencing of all coding exons of the p53 gene demonstrated only a neutral genetic polymorphism, i.e. a G-to-A substitution (GAG to GAA) at nucleotide position 13 432. Glycosaminoglycans 125-128 P53 Homo sapiens 38-41 15887239-3 2005 We demonstrated that vitamin C inhibits DNA synthesis in HeLa cells and, mainly the form of dehydroascorbic acid (DHA), delays the entry of p53-deficient synchronized HeLa and T98G cancer cells into mitosis. Ascorbic Acid 21-30 P53 Homo sapiens 140-143 12126965-5 2002 Addition of alpha-tocopherol before arsenite treatment abolished the transient increase in superoxide formation, lipid peroxidation, intracellular [Ca(2+)] levels and p53 gene expression, and furthermore could significantly inhibited the arsenite-induced apoptosis of MGC-803 cells. alpha-Tocopherol 12-28 P53 Homo sapiens 167-170 9773930-1 1998 To study the appropriate period for formalin fixation in order to detect p53 abnormalities in formalin-fixed tissue, we used seven surgically resected human colorectal cancer specimens. Formaldehyde 36-44 P53 Homo sapiens 73-76 9773930-1 1998 To study the appropriate period for formalin fixation in order to detect p53 abnormalities in formalin-fixed tissue, we used seven surgically resected human colorectal cancer specimens. Formaldehyde 94-102 P53 Homo sapiens 73-76 9773930-6 1998 PCR amplification for p53 at exon 8 and K-ras at codon 12 was successful until 1 day and 2 weeks, respectively, of formalin-fixation for the specimens of all seven cases. Formaldehyde 115-123 P53 Homo sapiens 22-25 9773930-9 1998 These results suggest that to detect p53 abnormality in specimens that have been formalin-fixed for long periods, immunohistochemical staining may have advantages over DNA analysis with PCR amplification. Formaldehyde 81-89 P53 Homo sapiens 37-40 9743293-8 1998 Thus, although p53-dependent apoptosis is induced by camptothecin, topotecan and SN-38 in this human ovarian carcinoma cell line, these drugs induce p53-independent death, as measured by clonogenic assay. Topotecan 67-76 P53 Homo sapiens 15-18 16234232-5 2005 The H2 helix of p53 structurally mimics the binding of ssDNA to the oligonucleotide/oligosaccharide-binding fold. Oligosaccharides 84-99 P53 Homo sapiens 16-19 9705861-4 1998 We show here that chronic treatment of human fibroblast with DAG induces p53 down-regulation and inhibition of p53 functional activity, and protection from UV-induced apoptosis. Diglycerides 61-64 P53 Homo sapiens 111-114 12085225-8 2002 In the PRI cells fludarabine activated p53, but not in the BL2.B95.8 cells in which the p53 pathway is inactivated. fludarabine 17-28 P53 Homo sapiens 39-42 12082016-9 2002 Further exploration of antimalarial compounds identified the common medicinals chloroquine, quinacrine, and amodiaquine as Tp53-inducers. Quinacrine 92-102 P53 Homo sapiens 123-127 12082016-9 2002 Further exploration of antimalarial compounds identified the common medicinals chloroquine, quinacrine, and amodiaquine as Tp53-inducers. Amodiaquine 108-119 P53 Homo sapiens 123-127 16204064-0 2005 Topotecan-triggered degradation of topoisomerase I is p53-dependent and impacts cell survival. Topotecan 0-9 P53 Homo sapiens 54-57 12046070-2 2002 METHODS: Two hundreds and forty-four formalin-fixed paraffin-embedded tumor samples of the patients with HCC receiving liver resection were detected for nuclear accumulation of p53. Formaldehyde 37-45 P53 Homo sapiens 177-180 9705861-5 1998 As PKC phosphorylation is necessary for p53 functional activity, we propose that chronic DAG treatment mimics the same event occurring in vivo for the effect of glycolysis in tumor progression. Diglycerides 89-92 P53 Homo sapiens 40-43 16204064-7 2005 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. Topotecan 184-193 P53 Homo sapiens 13-16 9743466-7 1998 Chimeric methylphosphonate-phosphodiester oligodeoxynucleotide antisense to a point mutation in KYO-1 p53 mRNA efficiently reduced target mRNA expression, but only small, transient reductions in p53 protein expression were observed. methylphosphonate-phosphodiester oligodeoxynucleotide 9-62 P53 Homo sapiens 102-105 11880381-7 2002 Finally, stable expression of the HPV16 E6 oncogene or dominant negative p53 peptide, GSE-22, both of which inhibit p53 function, delayed entry into quiescence following growth factor withdrawal. GSH monoMe ester 86-89 P53 Homo sapiens 73-76 9743466-8 1998 However, a chimeric methylphosphonate-phosphorothioate oligodeoxynucleotide targeted to the same site reduced p53 protein to 30% of control levels over a 48-hour period. methylphosphonate-phosphorothioate oligodeoxynucleotide 20-75 P53 Homo sapiens 110-113 11880381-7 2002 Finally, stable expression of the HPV16 E6 oncogene or dominant negative p53 peptide, GSE-22, both of which inhibit p53 function, delayed entry into quiescence following growth factor withdrawal. GSH monoMe ester 86-89 P53 Homo sapiens 116-119 16204064-7 2005 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. Topotecan 184-193 P53 Homo sapiens 104-107 16204064-11 2005 U138 cells (p53 mutated) were significantly more sensitive to topotecan than U87 cells (p53 wild-type). Topotecan 62-71 P53 Homo sapiens 12-15 16204064-14 2005 The data suggests that p53 causes resistance of cells to topo I inhibitors due to stimulation of topotecan-triggered topo I degradation which may impact topotecan-based cancer therapy. Topotecan 97-106 P53 Homo sapiens 23-26 9679939-0 1998 Alterations of the p53 gene in occupational bladder cancer in workers exposed to aromatic amines. aromatic amines 81-96 P53 Homo sapiens 19-22 16204064-14 2005 The data suggests that p53 causes resistance of cells to topo I inhibitors due to stimulation of topotecan-triggered topo I degradation which may impact topotecan-based cancer therapy. Topotecan 153-162 P53 Homo sapiens 23-26 12003538-10 2002 Moreover, it turned out that these phosmidosine derivatives showed characteristic inhibitory activities against cancer cells independent of their p53 phenotypes. phosmidosine 35-47 P53 Homo sapiens 146-149 9687575-10 1998 The results also suggest that p53 induction in response to O6-guanine methylation involves the mismatch repair system. 6-Oxamyristic acid 59-61 P53 Homo sapiens 30-33 15914462-4 2005 Both proline oxidase- and p53-induced activation of NFAT were sensitive to the calcineurin inhibitors cyclosporin A and FK-506, to scavengers of ROS, and to inhibitors of calcium mobilization. Tacrolimus 120-126 P53 Homo sapiens 26-29 9726816-0 1998 Induction of apoptosis by thiuramdisulfides, the reactive metabolites of dithiocarbamates, through coordinative modulation of NFkappaB, c-fos/c-jun, and p53 proteins. dithiocarbamates 73-89 P53 Homo sapiens 153-156 16012788-0 2005 Enhanced P53 and BAX gene expression and apoptosis in A549 cells by cis-Pt(II) complex of 3-aminoflavone in comparison with cis-DDP. 3-aminoflavone 90-104 P53 Homo sapiens 9-12 9726816-10 1998 These results suggested that PTDS and DTDS induced p53-dependent apoptosis, whereas PDTC, DDTC, and ADTC induced G1/S arrest. ptds 29-33 P53 Homo sapiens 51-54 9726816-10 1998 These results suggested that PTDS and DTDS induced p53-dependent apoptosis, whereas PDTC, DDTC, and ADTC induced G1/S arrest. 5'-O-(4,4'-dimethoxytrityl)thymidine-3'-O-(2,4-dinitrophenyl) succinate 38-42 P53 Homo sapiens 51-54 9703875-0 1998 Increased p21/WAF-1 and p53 protein levels following sequential three drug combination regimen of fludarabine, cytarabine and docetaxel induces apoptosis in human leukemia cells. fludarabine 98-109 P53 Homo sapiens 24-27 9698472-2 1998 Immunostaining for p53 protein was performed on formalin-fixed, paraffin-embedded sections from 158 patients with verified uterine sarcomas using monoclonal p53 antibody (DO-1). Formaldehyde 48-56 P53 Homo sapiens 19-22 9622079-1 1998 17-(Allylamino)-17-demethoxygeldanamycin (17AAG), a compound that is proposed for clinical development, shares the ability of geldanamycin to bind to heat shock protein 90 and GRP94, thereby depleting cells of p185erbB2, mutant p53, and Raf-1. geldanamycin 28-40 P53 Homo sapiens 228-231 12094375-8 2002 Nuclear p53 immunostaining was detected in 30% of IPN-L as a whole and increased in tandem with the progression of IPN-L (P < 0.01). isoamyl nitrite 50-53 P53 Homo sapiens 8-11 11929820-6 2002 We have designed allele-specific phosphorothioate ODNs against the gene of the large subunit of RNA polymerase II (POLR2A), a gene located in close proximity to the tumor suppressor gene p53, which frequently shows LOH in cancer cells. Parathion 33-49 P53 Homo sapiens 187-190 15996664-1 2005 Protein transduction therapy using poly-arginine can deliver the bioactive p53 protein into cancer cells and inhibits the proliferation of the cells. polyarginine 35-48 P53 Homo sapiens 75-78 11917017-9 2002 The non-detectable DNA binding of the 273H p53-CD is due mainly to the disruption of a hydrogen-bonding network involving R273, D281 and R280, leading to a loss of major groove binding by R280 and K120. 273h 38-42 P53 Homo sapiens 43-46 9635828-7 1998 The valine 272 residue may thus be crucial for properties (other than sequence-specific DNA binding) that are important for p53 function(s) in vivo. Valine 4-10 P53 Homo sapiens 124-127 9482877-1 1998 Treatment of mouse or human cells with the protein kinase C (PKC) inhibitors H7 or bisindolylmaleimide I induced an increase in the lifetime of p53, leading to its accumulation. bisindolylmaleimide I 83-104 P53 Homo sapiens 144-147 11912124-7 2002 These results indicate that the combination of TRAIL/Apo2L with either irradiation or sulindac may be highly effective against both p53-proficient and p53-deficient colorectal cancers; however, BAX-deficient tumors may evade elimination by TRAIL/Apo2L-based regimens. Sulindac 86-94 P53 Homo sapiens 132-135 16009942-7 2005 The UVB-induced lesions detected by terminal transferase-PCR were almost exclusively mapped to pyrimidine-rich sequences; however, the UVA1-induced lesions were mapped to purine- and pyrimidine-containing sequences along the p53 gene. pyrimidine 183-193 P53 Homo sapiens 225-228 11912124-7 2002 These results indicate that the combination of TRAIL/Apo2L with either irradiation or sulindac may be highly effective against both p53-proficient and p53-deficient colorectal cancers; however, BAX-deficient tumors may evade elimination by TRAIL/Apo2L-based regimens. Sulindac 86-94 P53 Homo sapiens 151-154 9562963-3 1998 Compared to BAP-p53, the BAP-TSPf group had a similar antitumor efficacy. benzylaminopurine 12-15 P53 Homo sapiens 16-19 11870884-4 2002 This cell line contains a mutation in codon 272 of p53 (p53(V272M), with methionine instead of a valine), conferring temperature-sensitive properties to the p53 protein. Valine 97-103 P53 Homo sapiens 51-54 15905035-9 2005 An antioxidant, l-ascorbic acid, inhibited CoQ2-induced p53 phosphorylation and further apoptotic stimuli.

Valine 97-103 P53 Homo sapiens 56-59 9562963-4 1998 More importantly, liposomes complexed with BAP-TSPf and BAP-p53 synergistically decreased the growth of MDA-MB-435 tumors when compared to either BAP-p53 or BAP-TSPf alone. benzylaminopurine 43-46 P53 Homo sapiens 150-153 9562963-4 1998 More importantly, liposomes complexed with BAP-TSPf and BAP-p53 synergistically decreased the growth of MDA-MB-435 tumors when compared to either BAP-p53 or BAP-TSPf alone. benzylaminopurine 56-59 P53 Homo sapiens 60-63 9562963-4 1998 More importantly, liposomes complexed with BAP-TSPf and BAP-p53 synergistically decreased the growth of MDA-MB-435 tumors when compared to either BAP-p53 or BAP-TSPf alone. benzylaminopurine 56-59 P53 Homo sapiens 150-153 9562963-4 1998 More importantly, liposomes complexed with BAP-TSPf and BAP-p53 synergistically decreased the growth of MDA-MB-435 tumors when compared to either BAP-p53 or BAP-TSPf alone. benzylaminopurine 56-59 P53 Homo sapiens 60-63 9562963-4 1998 More importantly, liposomes complexed with BAP-TSPf and BAP-p53 synergistically decreased the growth of MDA-MB-435 tumors when compared to either BAP-p53 or BAP-TSPf alone. benzylaminopurine 56-59 P53 Homo sapiens 150-153 15780621-1 2005 Crystallographic analysis of ligands bound to HDM2 suggested that 7-substituted 1,4-diazepine-2,5-diones could mimic the alpha-helix of p53 peptide and may represent a promising scaffold to develop HDM2-p53 antagonists. 7-substituted 1,4-diazepine-2,5-diones 66-104 P53 Homo sapiens 136-139 9773296-6 1998 The technique of microwave antigen retrieval gave crisp, clear immunohistochemical staining for p53 in tissues fixed in neutral buffered formalin or Bouin solution. Formaldehyde 137-145 P53 Homo sapiens 96-99 11786354-3 2002 We propose a method for the determination of traces of GST in the p53 C-terminus based on the constant current chronopotentiometric stripping analysis (CPSA) with hanging mercury drop electrode (HMDE). hmde 195-199 P53 Homo sapiens 66-69 11898040-10 2002 MSI appears to contribute to carcinogenesis in the biliary tract mucosa of PBM patients, and p53 mutations may be related to the development of GB cancer in the CCD group. ccd 161-164 P53 Homo sapiens 93-96 15780621-1 2005 Crystallographic analysis of ligands bound to HDM2 suggested that 7-substituted 1,4-diazepine-2,5-diones could mimic the alpha-helix of p53 peptide and may represent a promising scaffold to develop HDM2-p53 antagonists. 7-substituted 1,4-diazepine-2,5-diones 66-104 P53 Homo sapiens 203-206 9498829-8 1998 Cell labeling by staining with bromodeoxiuridine indicated that p53 is an important factor in modulating growth in NSCLC tumors. bromodeoxiuridine 31-48 P53 Homo sapiens 64-67 15748635-3 2005 In human skin cancers, about 35% of all mutations in the p53 gene are transitions at dipyrimidines within the sequence 5"-TCG and 5"-CCG, and these are localized at several mutational hotspots. dipyrimidines 85-98 P53 Homo sapiens 57-60 15748635-4 2005 Since 5"-CG sequences are methylated along the p53 coding sequence in human cells, these mutations may be derived from sunlight-induced pyrimidine dimers forming at sequences that contain 5-methylcytosine. pyrimidine 136-146 P53 Homo sapiens 47-50 15707991-5 2005 Furthermore, COX-2 interacted with p53 in vitro and in vivo, which was inhibited by the treatment with NS-398. N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide 103-109 P53 Homo sapiens 35-38 15678854-6 1998 Immunohistochemical determination of p53 protein was performed on tissular samples formalin fixed and paraffin embedded, using mouse monoclonal antibody DAKO--p53 DO 7 p53 human antiprotein. Formaldehyde 83-91 P53 Homo sapiens 37-40 9407038-7 1997 Low levels of phosphoserine-15 p53 are detectable within 6 hr after IR in AT cells, whereas lymphoblasts from normal individuals exhibit this modification within 1 hr. Phosphoserine 14-27 P53 Homo sapiens 31-34 11747348-5 2001 Western blot analysis indicated that Tyrphostin AG 1024-induced apoptosis was associated with a downregulation of expression of phospho-Akt1, increased expression of Bax, p53 and p21, and a decreased expression of bcl-2 expression, especially when combined with irradiation. Tyrphostins 37-47 P53 Homo sapiens 171-174 11554448-6 2001 Furthermore, we also review the available evidence on the role of p53 as a transactivator or transrepressor of genes involved in the production and control of reactive oxygen intermediates. reactive oxygen 159-174 P53 Homo sapiens 66-69 15715472-10 2005 The butyric acid and formaldehyde induced cell differentiation and increased p53 and p21 levels, suggesting that both affect cancer cells, the acid by inhibiting HDAC and the aldehyde by an as yet unknown mechanism. Formaldehyde 21-33 P53 Homo sapiens 77-80 11523059-10 2001 It is concluded that sennosides acutely induce apoptosis of colonic epithelial cells, presumably by a p53, p21/WAF-mediated pathway, resulting in shorter crypts. senokot 21-31 P53 Homo sapiens 102-105 9499672-17 1997 Finally, p53 tumor suppressor gene has been associated with resistance to therapy with fludarabine. fludarabine 87-98 P53 Homo sapiens 9-12 9267568-0 1997 Diagnostic implications of p53 protein reactivity in nasal mucosa of nickel workers. Nickel 69-75 P53 Homo sapiens 27-30 15720815-6 2005 GSP-induced apoptosis in JB6 C141 cells was associated with increased expression of the tumor-suppressor protein, p53, and its phosphorylation at Ser15. Grape Seed Proanthocyanidins 0-3 P53 Homo sapiens 114-117 9267568-1 1997 OBJECTIVE: To investigate whether the quantitation of p53 protein reactivity in nasal biopsies could be related to nickel exposure by comparing nickel workers with various control groups. Nickel 115-121 P53 Homo sapiens 54-57 9267568-5 1997 RESULTS: p53 Protein reactivity was found in 54% (49/93) of nickel workers, 50% (17/34) of office staff members, 67% (4/6) of hospital attendants. Nickel 60-66 P53 Homo sapiens 9-12 9267568-11 1997 CONCLUSION: Accumulation of p53 protein in nickel workers seems not to be attributable to nickel exposure. Nickel 43-49 P53 Homo sapiens 28-31 11466694-6 2001 RESULTS: In the NSCLC specimens, anticancer agents, including TZT-1027, showed strong antitumor activity against 50--75% of specimens with the wild type p53 gene. soblidotin 62-70 P53 Homo sapiens 153-156 11466694-11 2001 Therefore, TZT-1027 is expected to show similar antitumor activity against tumors with a loss of p53 function as well as those with normal function of p53 in clinical fields. soblidotin 11-19 P53 Homo sapiens 97-100 15576237-7 2004 Interestingly, CYP2D6-treated eugenol strongly damaged C and G of the 5"-ACG-3" sequence complementary to codon 273 of the p53 gene. Eugenol 30-37 P53 Homo sapiens 123-126 11451905-0 2001 Enhancement of fibrogenesis by the p53 tumor suppressor protein in asbestos-exposed rodents. Asbestos 67-75 P53 Homo sapiens 35-38 11453316-1 2001 The aim of this study is to investigate immunoreactivity for p53, p21 and metallothionein in diffuse malignant pleural mesothelioma (DMPM) and to determine the relationships between the age, sex, asbestos exposure time, survival of DMPM patients with environmental asbestos exposure and immunoreactivity to p53, p21 and metallothionein. dmpm 133-137 P53 Homo sapiens 61-64 9389352-8 1997 Treatment of CLL cells having wild type p53 with CdA, F-ara-A or CLB produced an increase in p53 protein and mdm-2 mRNA. Cladribine 49-52 P53 Homo sapiens 40-43 9389352-8 1997 Treatment of CLL cells having wild type p53 with CdA, F-ara-A or CLB produced an increase in p53 protein and mdm-2 mRNA. Cladribine 49-52 P53 Homo sapiens 93-96 9389352-8 1997 Treatment of CLL cells having wild type p53 with CdA, F-ara-A or CLB produced an increase in p53 protein and mdm-2 mRNA. fludarabine 54-61 P53 Homo sapiens 40-43 9389352-8 1997 Treatment of CLL cells having wild type p53 with CdA, F-ara-A or CLB produced an increase in p53 protein and mdm-2 mRNA. fludarabine 54-61 P53 Homo sapiens 93-96 9389352-11 1997 Treatment of CLL cells containing a wild type p53 gene with CdA, F-ara-A, or CLB, did not produce any consistent changes in bax or bcl-2. Cladribine 60-63 P53 Homo sapiens 46-49 9389352-12 1997 Thus, CdA, F-ara-A and CLB appear to act in CLL cells through a p53-dependent pathway, whereas this does not occur with dexamethasone or vincristine. Cladribine 6-9 P53 Homo sapiens 64-67 9812577-2 1997 Results showed that fragment of exon 7 or 8 of p53 gene in four cases was positive in silver-staining analysis of PCR-SSCP. Silver 86-92 P53 Homo sapiens 47-50 9812584-3 1997 Lanthanum chloride, cerium chloride and mixed rare-earth chloride at levels of 0.5 to 1.5 mmol/L could inhibit obviously growth of cancer cells and change cell morphology and microtubule structure of PAMC82, similar to that of normal cells, their colony-forming ability lowered in soft agar, and expression of tumor suppressor gene p53, p16 and p21 increased and that of gene nm23 lowered. Chlorides 10-18 P53 Homo sapiens 332-335 11358908-10 2001 All tumour regions showed a point mutation in p53 gene at exon 7 (GGC (glycine)-->GTC (valine) at codon 245). Valine 90-96 P53 Homo sapiens 46-49 11358908-11 2001 The distal portion of the duodenal tumour showed an additional point mutation in p53 gene at exon 5 (GCC (alanine)-->GTC (valine) at codon 129). Valine 125-131 P53 Homo sapiens 81-84 11494111-0 2001 Poly(ADP-ribosyl)ation of p53 in vitro and in vivo modulates binding to its DNA consensus sequence. poly(adp-ribosyl) 0-17 P53 Homo sapiens 26-29 9190897-0 1997 Geldanamycin-stimulated destabilization of mutated p53 is mediated by the proteasome in vivo. geldanamycin 0-12 P53 Homo sapiens 51-54 15547693-4 2004 The p53-mutated status of FaDu human pharynx carcinoma cell line was first assessed by DNA sequencing and the cells were transfected using tetraglucosylated polyethylenimine (PEI-Glu4) in conjunction with photochemical internalisation (PCI). pei-glu4 175-183 P53 Homo sapiens 4-7 9190897-5 1997 We found that this impairment of p53 turnover can be reversed by treatment of tumor cells with the benzoquinone ansamycin, geldanamycin, leading to a marked reduction in intracellular p53 levels. geldanamycin 123-135 P53 Homo sapiens 33-36 9190897-5 1997 We found that this impairment of p53 turnover can be reversed by treatment of tumor cells with the benzoquinone ansamycin, geldanamycin, leading to a marked reduction in intracellular p53 levels. geldanamycin 123-135 P53 Homo sapiens 184-187 9190897-6 1997 Finally, using cells which over-express a mutant p53 protein, we were able to demonstrate that restoration of proteasome-mediated degradation by geldanamycin is accompanied by p53 polyubiquitination. geldanamycin 145-157 P53 Homo sapiens 49-52 11289281-4 2001 METHODS: Mutation screening of the hot spots of the K-ras gene and of the evolutionarily conserved regions of the TP53 gene was performed by denaturing gradient gel electrophoresis technique in formalin-fixed paraffin-embedded specimens of 55 consecutive patients with Dukes C colon cancer treated with adjuvant 5-fluorouracil-based chemotherapy. Formaldehyde 194-202 P53 Homo sapiens 114-118 15358769-2 2004 We show that geldanamycin or radicicol, specific inhibitors of Hsp90, diminish specific wild-type p53 binding to the p21 promoter sequence. geldanamycin 13-25 P53 Homo sapiens 98-101 11273776-3 2001 In this report, we describe an improved extruded DOTAP:cholesterol (DOTAP:Chol) cationic liposome that efficiently delivers therapeutic tumor suppressor genes p53 and FHIT, which are frequently altered in lung cancer, to localized human primary lung cancers and to experimental disseminated metastases. chol 74-78 P53 Homo sapiens 159-162 11273776-5 2001 When treated with DOTAP:Chol-p53 and -FHIT complex, significant suppression was observed in both primary (P < 0.02) and metastatic lung tumor growth (P < 0.007). chol 24-28 P53 Homo sapiens 29-32 11797833-0 2001 Low levels of p53 mutations in Indian patients with osteosarcoma and the correlation with fluoride levels in bone. Fluorides 90-98 P53 Homo sapiens 14-17 11797833-3 2001 We were interested in exploring the possible relationship between fluoride bone content and p53 mutations. Fluorides 66-74 P53 Homo sapiens 92-95 9190897-6 1997 Finally, using cells which over-express a mutant p53 protein, we were able to demonstrate that restoration of proteasome-mediated degradation by geldanamycin is accompanied by p53 polyubiquitination. geldanamycin 145-157 P53 Homo sapiens 176-179 9190897-7 1997 Although much remains to be learned about the mechanisms involved, our data demonstrate that selective de-stabilization of mutant transforming proteins such as p53 can be achieved pharmacologically with agents such as geldanamycin which modify the function of molecular chaperone proteins within tumor cells. geldanamycin 218-230 P53 Homo sapiens 160-163 9815713-8 1997 Growth of NPC cells treated with Ad5CMV-p53 was observed to be significantly inhibited when determined by either the 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide or clonogenic assay. thiazolyl blue 117-178 P53 Homo sapiens 40-43 15358769-11 2004 Consistent with our in vivo results, geldanamycin can suppress Hsp90 ability to regulate in vitro p53 DNA binding to the promoter sequence. geldanamycin 37-49 P53 Homo sapiens 98-101 15217838-8 2004 Nuclear translocation of p53 after fludarabine treatment was decreased when STAT1beta was overexpressed, and it was increased when STAT1alpha was induced. fludarabine 35-46 P53 Homo sapiens 25-28 9260591-4 1997 The expression of the proteins p53 and mdm2 was determined immunohistochemically using formalin-fixed, paraffin-embedded material. Formaldehyde 87-95 P53 Homo sapiens 31-34 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Valine 178-184 P53 Homo sapiens 67-70 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Valine 178-184 P53 Homo sapiens 157-160 11351862-5 2000 The Northern blot analysis revealed marked up-regulation of p53, p16(MTS1), p21 (WAF1) gene expressions in PAMC82 cells treated with lanthanum chloride and cerium chloride, as compared to control PAMC82 cells. cerous chloride 156-171 P53 Homo sapiens 60-63 11029511-10 2000 These data indicate that synergistic growth inhibition by UCN-01 and CPT against p53 mutant MDA-MB-231 tumor cells may be due to induction of DSBs however the loss of p53 function alone does not sensitize normal cells to the combination of both drugs. dsbs 142-146 P53 Homo sapiens 81-84 15217838-10 2004 Our results show that imbalance between the antiproliferative/proapoptotic isoform STAT1alpha and the proliferative isoform STAT1beta is likely to play a crucial role in the regulation of proliferation and apoptosis and that STAT1alpha may regulate p53 activity and sensitize B cells to fludarabine-induced apoptosis. fludarabine 287-298 P53 Homo sapiens 249-252 11079153-2 2000 Clonogenic survival studies indicate that EB 1089 shifts the dose-response curve for sensitivity to adriamycin by approximately six-fold in p53 wild-type MCF-7 cells; comparative studies in MCF-7 cells with a temperature-sensitive dominant negative p53 mutation show less than a two-fold shift in adriamycin sensitivity in the presence of EB 1089. ethylbenzene 42-44 P53 Homo sapiens 140-143 11079153-2 2000 Clonogenic survival studies indicate that EB 1089 shifts the dose-response curve for sensitivity to adriamycin by approximately six-fold in p53 wild-type MCF-7 cells; comparative studies in MCF-7 cells with a temperature-sensitive dominant negative p53 mutation show less than a two-fold shift in adriamycin sensitivity in the presence of EB 1089. ethylbenzene 42-44 P53 Homo sapiens 249-252 9387525-2 1996 METHODS: Mutations in exons 5-8 of p53 gene in 41 patients with primary ovarian cancer were screened by polymerase chain reaction-single strand conformation polymorphism analysis with non-isotopic silver staining method. Silver 197-203 P53 Homo sapiens 35-38 8870682-4 1996 With the use of S-nitroglutathione (GSNO) we correlated a dose-dependent p53 up-regulation to DNA fragmentation measured after 4 h and 8 h, respectively. S-nitroglutathione 16-34 P53 Homo sapiens 73-76 15456252-6 2004 An NMR-docked model of one such inhibitor, pentamidine, bound to Ca(2+)-loaded S100B was calculated using intermolecular NOE data between S100B and the drug, and indicates that pentamidine binds into the p53 binding site on S100B defined by helices 3 and 4 and loop 2 (termed the hinge region). Pentamidine 43-54 P53 Homo sapiens 204-207 9816112-7 1996 We also find that induction of wild-type p53 potentiates the cytotoxicity of topotecan, a member of the camptothecin family of drugs that also has clinical activity against colon cancer. Topotecan 77-86 P53 Homo sapiens 41-44 10953164-0 2000 Brefeldin A induces p53-independent apoptosis in primary cultures of human prostatic cancer cells. Brefeldin A 0-11 P53 Homo sapiens 20-23 10953164-5 2000 Immunoblots were used to monitor p53 and pRB expression in response to BFA. Brefeldin A 71-74 P53 Homo sapiens 33-36 10953164-12 2000 CONCLUSIONS: BFA is a potent inducer of apoptosis in prostatic cancer cells via a p53-independent mechanism. Brefeldin A 13-16 P53 Homo sapiens 82-85 10953164-14 2000 Since p53-mediated pathways of apoptosis may frequently be abrogated in prostatic cancer cells, agents such as BFA that induce p53-independent cell death may be promising candidates for chemotherapeutic agents. Brefeldin A 111-114 P53 Homo sapiens 6-9 10953164-14 2000 Since p53-mediated pathways of apoptosis may frequently be abrogated in prostatic cancer cells, agents such as BFA that induce p53-independent cell death may be promising candidates for chemotherapeutic agents. Brefeldin A 111-114 P53 Homo sapiens 127-130 8855263-0 1996 p53-dependent cell cycle arrest induced by N-acetyl-L-leucinyl-L-leucinyl-L-norleucinal in platelet-derived growth factor-stimulated human fibroblasts. n-acetyl-l-leucinyl-l-leucinyl 43-73 P53 Homo sapiens 0-3 15456252-6 2004 An NMR-docked model of one such inhibitor, pentamidine, bound to Ca(2+)-loaded S100B was calculated using intermolecular NOE data between S100B and the drug, and indicates that pentamidine binds into the p53 binding site on S100B defined by helices 3 and 4 and loop 2 (termed the hinge region). Pentamidine 177-188 P53 Homo sapiens 204-207 15373832-2 2004 Using p53 deletion mutants, we have previously shown that the p53 C-terminal DNA-binding site (CTDBS) is critical for this binding. ctdbs 95-100 P53 Homo sapiens 6-9 8831555-6 1996 BFA-induced apoptosis is p53-independent as HL60 and K562 cells are p53 null and HT-29 are p53 mutant cells. Brefeldin A 0-3 P53 Homo sapiens 25-28 8831555-6 1996 BFA-induced apoptosis is p53-independent as HL60 and K562 cells are p53 null and HT-29 are p53 mutant cells. Brefeldin A 0-3 P53 Homo sapiens 68-71 10910962-1 2000 Simultaneous labelling of 17cen and the p53 locus by multicolour FISH was used to monitor radioactive iodine-induced structural and numerical chromosome abnormalities in buccal cells from 29 hyperthyroidism and thyroid cancer patients sampled before and after therapeutic treatment. Iodine 102-108 P53 Homo sapiens 40-43 8831555-6 1996 BFA-induced apoptosis is p53-independent as HL60 and K562 cells are p53 null and HT-29 are p53 mutant cells. Brefeldin A 0-3 P53 Homo sapiens 68-71 15373832-2 2004 Using p53 deletion mutants, we have previously shown that the p53 C-terminal DNA-binding site (CTDBS) is critical for this binding. ctdbs 95-100 P53 Homo sapiens 62-65 15724841-4 2004 In this study, we report the implication of p53 on growth arrest and apoptosis following the combined treatment of human mammary epithelial cells with topotecan, a specific topoisomerase I inhibitor, and UCN-01. Topotecan 151-160 P53 Homo sapiens 44-47 10972990-3 2000 In this study, we demonstrate that the deficiency of wild-type p53 protein may allow unrepaired DSBs to initiate chromosomal instability. dsbs 96-100 P53 Homo sapiens 63-66 10972990-11 2000 In wild-type p53 cells, spontaneous DSBs appear to be promptly repaired through recombination between homologous chromosomes. dsbs 36-40 P53 Homo sapiens 13-16 15724841-9 2004 Detailed cell-cycle analyses revealed that UCN-01 abrogated S-phase accumulation induced by topotecan treatment in p53 defective MDA231 tumor cells and HMEC/E6 cells. Topotecan 92-101 P53 Homo sapiens 115-118 10930428-2 2000 Several attempts to generate an antibody to p53 phosphorylated at Ser(6) using a phosphoserine-containing peptide as an immunogen were unsuccessful; however, phosphorylation-specific antibodies were produced by using the phosphoserine mimetic, l-2-amino-4-phosphono-4, 4-difluorobutanoic acid (F(2)Pab), in place of phosphoserine. Phosphoserine 81-94 P53 Homo sapiens 44-47 8875051-1 1996 It has been demonstrated that temperature-sensitive mutant p53 (val-->ala143) inhibits cell-proliferation at the permissive temperature, albeit to a lesser extent than wild-type p53 (Zhang et al. Valine 64-67 P53 Homo sapiens 59-62 10930428-2 2000 Several attempts to generate an antibody to p53 phosphorylated at Ser(6) using a phosphoserine-containing peptide as an immunogen were unsuccessful; however, phosphorylation-specific antibodies were produced by using the phosphoserine mimetic, l-2-amino-4-phosphono-4, 4-difluorobutanoic acid (F(2)Pab), in place of phosphoserine. Phosphoserine 221-234 P53 Homo sapiens 44-47 15724841-12 2004 These data indicate that UCN-01 selectively enhances topotecan cytotoxicity in p53 defective cells through the induction of apoptotic signaling pathway(s), although the time course for the induction of cell death is not the same. Topotecan 53-62 P53 Homo sapiens 79-82 10930428-2 2000 Several attempts to generate an antibody to p53 phosphorylated at Ser(6) using a phosphoserine-containing peptide as an immunogen were unsuccessful; however, phosphorylation-specific antibodies were produced by using the phosphoserine mimetic, l-2-amino-4-phosphono-4, 4-difluorobutanoic acid (F(2)Pab), in place of phosphoserine. l-2-amino-4-phosphono-4, 4-difluorobutanoic acid 244-292 P53 Homo sapiens 44-47 10930428-2 2000 Several attempts to generate an antibody to p53 phosphorylated at Ser(6) using a phosphoserine-containing peptide as an immunogen were unsuccessful; however, phosphorylation-specific antibodies were produced by using the phosphoserine mimetic, l-2-amino-4-phosphono-4, 4-difluorobutanoic acid (F(2)Pab), in place of phosphoserine. Phosphoserine 221-234 P53 Homo sapiens 44-47 15724841-13 2004 UCN-01 may, therefore, provide a new modality for topotecan-based therapy, particularly in p53 defective cancer patients. Topotecan 50-59 P53 Homo sapiens 91-94 8879300-2 1996 The accumulation of p53 protein was studied immunohistochemically using monoclonal antibody BP53-12 on formalin-fixed paraffin-embedded sections of 36 KS lesions, of which 14 were classified histologically as early type and 22 as spindle-cell or mixed type. Formaldehyde 103-111 P53 Homo sapiens 20-23 15374966-8 2004 Inhibition of p53 and caspases with alpha-pifithrin and z-Val-Ala-Asp-fluoromethyl ketone, respectively, blocked UVB- and doxorubicin-induced apoptosis in ATRA-treated KCs. alpha-pifithrin 36-51 P53 Homo sapiens 14-17 10884347-4 2000 Peptide competition studies have localized a cyclin A interaction site to a Lys381Lys382Leu383Met384Phe385 sequence within C-terminal negative regulatory domain of human p53. lys381lys382leu383met384phe385 76-106 P53 Homo sapiens 170-173 8782209-10 1996 We used the DO-7 monoclonal antibody reactive for the N-terminal of the p53 protein on formalin-fixed paraffin-embedded tissue. Formaldehyde 87-95 P53 Homo sapiens 72-75 15551755-2 2004 A previous study showed that 11 poly-arginine fused p53 protein (11R-p53) effectively penetrated across the plasma membrane and inhibited the proliferation of oral cancer cells. polyarginine 32-45 P53 Homo sapiens 52-55 15551755-2 2004 A previous study showed that 11 poly-arginine fused p53 protein (11R-p53) effectively penetrated across the plasma membrane and inhibited the proliferation of oral cancer cells. polyarginine 32-45 P53 Homo sapiens 69-72 10903257-8 2000 p53 expression evaluated by immunohistochemistry was frequently observed in dysplasias from pneumoconiosis with DIF, although it was not significantly different compared with that in dysplasias from pneumoconiosis without DIF (5 [50%] of 10 versus 12 [38%] of 32). Diclofenac 112-115 P53 Homo sapiens 0-3 15252149-10 2004 Attenuating p53 by a chemical inhibitor pifithrin-alpha decreased the selenite-induced p53 Ser15P and led to concordant reductions of PARP cleavage and apoptosis. Selenious Acid 70-78 P53 Homo sapiens 12-15 10918568-8 2000 Secondly, azadeoxycytidine reactivation of the silent hMLH1 gene or expression of a transfected hMLH1 cDNA sensitized the doubly hMLH1/p53 deficient cells only slightly to cisplatin. azadeoxycytidine 10-26 P53 Homo sapiens 135-138 8787547-11 1996 Together with earlier results showing downmodulation for IL-8 receptor type A expression in cultured KC treated with FK506, these results suggest that both the mitogenic IL-8/IL-8R system and the cell cycle inhibitor p53 represent potential targets for the antipsoriatic action of the drug, whereas protooncogenes acting downstream in mitogenic signal transduction cascades are unaffected. Tacrolimus 117-122 P53 Homo sapiens 217-220 15252149-10 2004 Attenuating p53 by a chemical inhibitor pifithrin-alpha decreased the selenite-induced p53 Ser15P and led to concordant reductions of PARP cleavage and apoptosis. Selenious Acid 70-78 P53 Homo sapiens 87-90 15252149-11 2004 In summary, selenite-induced p53 Ser15P appeared to be important for activating the caspase-mediated apoptosis involving both the caspase-8 and the caspase-9 pathways in the LNCaP cells. Selenious Acid 12-20 P53 Homo sapiens 29-32 10929428-14 2000 Mutant p53 expression was more decreased in the EJ cells treated with RA or Ni(RA)2.3H2O than in the control. ni(ra)2.3h2o 76-88 P53 Homo sapiens 7-10 15461257-1 2004 OBJECTIVE: To study the effects of DNA damage and apoptosis and p53 expression, and to explore the relationship between apoptosis and p53 expression in human embryo hepatocytes induced by fluoride. Fluorides 188-196 P53 Homo sapiens 134-137 8691338-2 1996 Stabilization of the p53 gene product was analysed by immunohistochemistry and proliferative activity was determined flow cytometrically and by silver staining of nucleolar organizer regions (AgNORs). Silver 144-150 P53 Homo sapiens 21-24 15461257-7 2004 CONCLUSION: Fluoride can increase the rate of DNA damage, and induce apoptosis and expression of p53 in human embryo hepatocytes. Fluorides 12-20 P53 Homo sapiens 97-100 15461257-8 2004 Furthermore, both apoptosis and the level of p53 expression, there exists a rise tendency with the increase concentration of fluoride. Fluorides 125-133 P53 Homo sapiens 45-48 14751514-12 2004 The other 50% was attributed to the p53-dependent permanent G1 arrest, because cells lacking in functional p53 (LFS2800, FaDu, CHO) showed a ratio of LE:CA = 1.01 +/- 0.02:1. CAV protocol 127-130 P53 Homo sapiens 36-39 8606380-5 1996 METHODS: Immunohistochemical analysis with a monoclonal antibody (DO7) specific for p53 protein was used to detect expression of the protein in formalin-fixed, paraffin-embedded tumor samples from 69 head and neck cancer patients treated with definitive local therapy (surgery and/or radiotherapy) between January 1980 and October 1983 at The University of Texas M. D. Anderson Cancer Center. Formaldehyde 144-152 P53 Homo sapiens 84-87 14751514-12 2004 The other 50% was attributed to the p53-dependent permanent G1 arrest, because cells lacking in functional p53 (LFS2800, FaDu, CHO) showed a ratio of LE:CA = 1.01 +/- 0.02:1.

Parathion 74-90 P53 Homo sapiens 60-63 14744793-4 2004 We have shown previously that perifosine induces p21(waf1/cip1) in a p53-independent fashion and that induction of p21(waf1/cip1) is required for the perifosine-induced cell cycle arrest because cell lines lacking p21(waf1/cip1) are refractory to perifosine. perifosine 30-40 P53 Homo sapiens 69-72 8648390-2 1996 In vitro incubation of acute myelogenous leukemia with OL(1)p53, a 20-mer phosphorothioate oligonucleotide complementary to p53 mRNA, results in leukemic cell death. Parathion 74-90 P53 Homo sapiens 124-127 8648390-13 1996 CONCLUSION: A phosphorothioate oligonucleotide, OL(1)p53, can be administered systemically without complications. Phosphorothioate Oligonucleotides 14-46 P53 Homo sapiens 53-56 8733010-7 1996 Omitting the cAMP stimulus prevents the p53-induced apoptosis in these cells, suggesting cross-talk between p53 and c-AMP-generated signals in the induction of apoptosis. c-amp 116-121 P53 Homo sapiens 40-43 14744793-7 2004 Using several p21(waf1/cip1) promoter-driven luciferase reporter plasmids, we observed that perifosine activates the 2.4-kb full-length p21(waf1/cip1) promoter as well as a p21 promoter construct lacking p53-binding sites, suggesting that perifosine activates the p21(waf1/cip1) promoter independent of p53. perifosine 92-102 P53 Homo sapiens 204-207 14744793-7 2004 Using several p21(waf1/cip1) promoter-driven luciferase reporter plasmids, we observed that perifosine activates the 2.4-kb full-length p21(waf1/cip1) promoter as well as a p21 promoter construct lacking p53-binding sites, suggesting that perifosine activates the p21(waf1/cip1) promoter independent of p53. perifosine 92-102 P53 Homo sapiens 303-306 14698413-10 2004 Based on the results from Tester Strain TA7005, it indicate that BPT and its most mutagenic metabolite BPT sulfoxide induce predominantly CG --> AT transversion, which is observed as the most frequent base substitution mutation of p53 tumor-suppressor gene in human lung cancer. bpt sulfoxide 103-116 P53 Homo sapiens 234-237 8649821-0 1996 ETS1 and ETS2 in p53 regulation: spatial separation of ETS binding sites (EBS) modulate protein: DNA interaction. ethylbenzene 74-77 P53 Homo sapiens 17-20 8600043-10 1996 p53 staining was associated with juvenile type GCTs (P<.001) and higher Ki67PI (P<.005). ki67pi 75-81 P53 Homo sapiens 0-3 14682762-0 2003 Solid-phase synthesis of the cyclic peptide portion of chlorofusin, an inhibitor of p53-MDM2 interactions.

Asbestos 121-129 P53 Homo sapiens 31-34 8152811-4 1994 We therefore introduced the pC53-SCX3 143 (Val-Ala) p53 mutation into a non tumorigenic adenoma derived cell line, AA/C1, which contained a truncating APC mutation, activating K-ras mutation but was wild-type for the p53 protein. Valine 43-46 P53 Homo sapiens 52-55 9886570-3 1998 Exons 5-8 of the p53 gene were examined for mutations by the polymerase chain reaction-single strand conformation polymorphism technique and DNA sequencing, using DNA from formalin-fixed paraffin-embedded tissues. Formaldehyde 172-180 P53 Homo sapiens 17-20 12064559-7 2002 Further studies are needed to examine whether the observed mutation of the p53 suppressor gene is due to the combined effects of asbestos and smoking or to other unknown factors. Asbestos 129-137 P53 Homo sapiens 75-78 9732400-6 1998 Transfer of a mutant p53 gene enhanced topotecan sensitivity in wild-type p53 LN-229 but not mutant p53 LN-18 cells. Topotecan 39-48 P53 Homo sapiens 74-77 8043159-9 1994 Since p53 (PAb 1801) expression can withstand formalin fixation and pepsin treatment of paraffin-embedded tissues, flow cytometric analysis of archival specimens is feasible, and clinical correlations such as these may be carried out in retrospective studies of other tumors. Formaldehyde 46-54 P53 Homo sapiens 6-9 18968561-1 2002 Single nucleotide polymorphisms (SNPs) of cancer repression gene p53 were analyzed electrochemically with ferrocenyl naphthalene diimide (1) as a hybridization indicator. ferrocenylnaphthalene diimide 106-136 P53 Homo sapiens 65-68 8156496-3 1994 METHODS: The status of the p53 gene was studied by immunohistochemistry of formalin-fixed paraffin-embedded biopsy samples from 72 patients with atypical endometrial hyperplasia or endometrioid carcinoma who underwent hysterectomy immediately after biopsy and from 5 patients with benign endometria. Formaldehyde 75-83 P53 Homo sapiens 27-30 9668066-4 1998 In this communication, we report that PDTC inhibits the activation of temperature-sensitive murine p53(Val-135) (TSp53) in the transformed rat embryo fibroblast line, A1-5, as well as wild-type human p53 in the normal diploid fibroblast line, WS1neo. Valine 103-106 P53 Homo sapiens 115-118 9688570-0 1998 Disruption of actin microfilaments by cytochalasin D leads to activation of p53. Cytochalasin D 38-52 P53 Homo sapiens 76-79 9688570-2 1998 We investigated whether p53 is activated upon disruption of actin microfilaments, caused by cytochalasin D (CD).

Formaldehyde 153-161 P53 Homo sapiens 38-41 9626464-3 1998 The expression of p53, bcl-2, thymidylate synthase (TS), glutathione S-transferase pi (GST-pi), and vascular endothelial growth factor (VEGF) in the formalin-fixed biopsy samples of primary tumors before chemotherapy was examined immunohistochemically. Formaldehyde 149-157 P53 Homo sapiens 18-21 11864911-1 2002 We have investigated the mechanism of S-phase arrest elicited by the carcinogen benzo(a)pyrene dihydrodiol epoxide (BPDE) in p53-deficient cells. pyrene dihydrodiol epoxide 88-114 P53 Homo sapiens 125-128 9610736-2 1998 We now show that UV irradiation of B16 melanoma after prior exposure to the radiation sensitizer, bromodeoxyuridine (BUdR) leads to induction of p53 and DNA fragmentation, and concomitant decreases in Rb, E2F, cyclin D1, and cell viability, with no comparable effects on irradiated unsensitized cells. Bromodeoxyuridine 98-115 P53 Homo sapiens 145-148 7901994-13 1993 We conclude that the immunohistochemical detection of p53 nuclear accumulation in formalin-fixed, paraffin-embedded tissue is highly associated with mutations in the p53 gene; this association has now been demonstrated in a large number of tumors. Formaldehyde 82-90 P53 Homo sapiens 54-57 7901994-13 1993 We conclude that the immunohistochemical detection of p53 nuclear accumulation in formalin-fixed, paraffin-embedded tissue is highly associated with mutations in the p53 gene; this association has now been demonstrated in a large number of tumors.

Formaldehyde 55-63 P53 Homo sapiens 40-43 7692889-8 1993 RESULTS: An antigen retrieval method facilitated the unmasking of previously inaccessible p53 antigenic determinants in formalin-fixed, paraffin-embedded tissues. Formaldehyde 120-128 P53 Homo sapiens 90-93 7692889-11 1993 CONCLUSIONS: Antigen retrieval method in formalin-fixed, paraffin-embedded tissue demonstrated a significant increase in p53 immunostaining. Formaldehyde 41-49 P53 Homo sapiens 121-124 9540056-5 1998 Four recurrent meningiomas with high p53 PIs were analyzed by the polymerase chain reaction-single strand conformation polymorphism method to detect p53 gene mutations, but none were found in exons 4-8 of this gene. Monothiopyrophosphoric acid 41-44 P53 Homo sapiens 37-40 9609668-0 1998 Simultaneous detection of p53 nuclear protein and chromosome aberrations on sections from formalin-fixed, paraffin-embedded breast cancer tissue. Formaldehyde 90-98 P53 Homo sapiens 26-29 9535218-6 1998 These results indicate that in oxLDL-induced apoptosis, a concomitant induction of p53 and MnSOD is critical, and suggest that it is at least in part due to an enhancement of the sphingomyelin/ceramide pathway. Sphingomyelins 179-192 P53 Homo sapiens 83-86 8252351-3 1993 Positive staining for p53 protein was detected in ten of 77 (13 per cent) of these tumours using polyclonal CM1 antibody on formalin-fixed tissue. Formaldehyde 124-132 P53 Homo sapiens 22-25 8406999-8 1993 Transfection of a mutant p53 gene construct (containing a mutation at codon 143, val to ala) into the A2780/cp70 resistant cells conferred a significantly increased sensitivity to cisplatin, suggesting that p53 is a direct determinant of cisplatin resistance in these cells. Valine 81-84 P53 Homo sapiens 25-28 8406999-8 1993 Transfection of a mutant p53 gene construct (containing a mutation at codon 143, val to ala) into the A2780/cp70 resistant cells conferred a significantly increased sensitivity to cisplatin, suggesting that p53 is a direct determinant of cisplatin resistance in these cells. Valine 81-84 P53 Homo sapiens 207-210 11779115-7 2002 Using this assay, we have demonstrated that a peptide with a nonhydrolyzable beta-amino acid substitution binds DM2 with an affinity comparable to a p53 peptide that is composed of only alpha-amino acids.

Formaldehyde 63-71 P53 Homo sapiens 22-25 9417863-13 1997 We suggest that a second chaperone protein, called p23, which we show also binds p53, may play an important role in these GA-mediated effects. geldanamycin 122-124 P53 Homo sapiens 81-84 9368180-0 1997 Ex vivo treatment of bone marrow with phosphorothioate oligonucleotide OL(1)p53 for autologous transplantation in acute myelogenous leukemia and myelodysplastic syndrome.

Silver 54-60 P53 Homo sapiens 31-34 11576999-13 2001 Since over 50% of human tumors contain a functionally defective p53 that reduces sensitivity to commonly used chemotherapeutic agents, such as etoposide and cisplatin, the ability of tachpyridine to induce apoptosis independently of p53 may offer an advantage in anti-tumor therapy. tachpyr 183-195 P53 Homo sapiens 64-67 1319835-9 1992 Also, carcinoma cells with p53 mutations existing within adenoma tissues are detectable by immunostaining, even in formalin-fixed, paraffin-embedded specimens.

Formaldehyde 122-130 P53 Homo sapiens 13-16 1569122-5 1992 Most importantly, they also permit the detection of p53 in archival tumour material that has been conventionally fixed in formalin and embedded in paraffin wax. Formaldehyde 122-130 P53 Homo sapiens 52-55 11313463-3 2001 p53-DNA complexes were cross-linked in vivo by treating the cells with formaldehyde and processed by chromatin immunoprecipitation-PCR. Formaldehyde 71-83 P53 Homo sapiens 0-3 1528930-5 1992 In most cases, the mutations in ras and p53 genes are localized to pyrimidine-rich sequences, particularly C-C sequences, which indicates that these sites are probably the targets for UV-induced DNA damage and subsequent mutation and transformation. pyrimidine 67-77 P53 Homo sapiens 40-43 21044462-9 2001 The different biological effect between 172Leu and 172His shows that some p53 variants such as 172 Arg->Leu may act as wild-type p53. 172leu 40-46 P53 Homo sapiens 74-77 9400941-3 1997 The potential of CdA to induce the p53-dependent DNA damage response was assessed in resting and phytohaemagglutinine (PHA)-activated peripheral blood mononuclear cells (PBMCs) and compared with cisplatin (DDP), a cell cycle-dependent and DNA-damaging agent that is mainly used in the treatment of solid tumours. Cladribine 17-20 P53 Homo sapiens 35-38 9400941-9 1997 Activation of the p53-dependent DNA damage response seems to be an important component of the toxic effect of CdA. Cladribine 110-113 P53 Homo sapiens 18-21 21044462-9 2001 The different biological effect between 172Leu and 172His shows that some p53 variants such as 172 Arg->Leu may act as wild-type p53. 172leu 40-46 P53 Homo sapiens 132-135 11401473-0 2001 Vitamin C augments chemotherapeutic response of cervical carcinoma HeLa cells by stabilizing P53. Ascorbic Acid 0-9 P53 Homo sapiens 93-96 1959638-4 1991 The purified protease processed the natural substrate gag precursor (p53) to form gag p19 and gag p24. Glycosaminoglycans 54-57 P53 Homo sapiens 69-72 1959638-4 1991 The purified protease processed the natural substrate gag precursor (p53) to form gag p19 and gag p24. Glycosaminoglycans 82-85 P53 Homo sapiens 69-72 9868114-2 1997 The results showed that overexpression of p53 was detected in 54.8% (23/42) of L-GSCC and 20% (5/25) of hyperlasia epithelia, respectively. l-gscc 79-85 P53 Homo sapiens 42-45 1959638-4 1991 The purified protease processed the natural substrate gag precursor (p53) to form gag p19 and gag p24. Glycosaminoglycans 82-85 P53 Homo sapiens 69-72 11401473-4 2001 Our findings show that vitamin C downregulates the redox sensitive transcription factor AP-1 and decreases one of its transcription targets HPV E6, and stabilizes P53. Ascorbic Acid 23-32 P53 Homo sapiens 163-166 11125034-7 2001 Notably, when MDM2 expression is inhibited in S-type cells, with a phosphorothioated antisense oligonucleotide (AS5), then p53 accumulates in the nucleus and the SH-EP1 cells undergo apoptosis. AS5 112-115 P53 Homo sapiens 123-126 9342752-6 1997 Our results indicate that IHC could be applied for studies of p53 protein accumulation in archival formalin fixed, paraffin-embedded bladder tumours. Formaldehyde 99-107 P53 Homo sapiens 62-65 11311793-0 2001 Inhibition of 6-hydroxydopamine-induced p53 expression and survival of neuroblastoma cells following interaction with astrocytes.

Silver 157-163 P53 Homo sapiens 14-17 11311793-8 2001 Western blot analysis demonstrated that 6-hydroxydopamine significantly increased p53 protein in monolayer SH-SY5Y cells grown in either regular medium or conditioned medium from astrocytes. Oxidopamine 40-57 P53 Homo sapiens 82-85 8810317-1 1996 We have examined in detail the DNA binding properties of several immunopurified tumor-derived mutant p53 proteins (Val-143 --> Ala, Arg-175 --> His, Arg-248 --> Trp, Arg-249 --> Ser, and Arg-273 --> His). Valine 115-118 P53 Homo sapiens 101-104 1793482-4 1991 Because the mutations in the p53 tumor suppressor gene in both tumors were located opposite potential pyrimidine dimer sites (C-C), it is consistent with these mutations having been induced by the ultraviolet radiation present in sunlight. pyrimidine 102-112 P53 Homo sapiens 29-32 8875976-5 1996 Similarly, multiple p53NK activities were detected in the MethAp53(ts) cell line (which expresses the valine 135 temperature-sensitive p53 protein). Valine 102-108 P53 Homo sapiens 20-23 11311793-11 2001 The enhanced resistance of the co-cultured SH-SY5Y cells to the toxicity of 6-hydroxydopamine is attributed to the ability of astrocytes to prevent the increase of p53 induced by this toxin. Oxidopamine 76-93 P53 Homo sapiens 164-167 8875976-5 1996 Similarly, multiple p53NK activities were detected in the MethAp53(ts) cell line (which expresses the valine 135 temperature-sensitive p53 protein). Valine 102-108 P53 Homo sapiens 63-66 11103796-8 2000 Wortmannin, an inhibitor of phosphatidylinositol 3-kinases, inhibited arsenite- or X-ray irradiation-induced p53 accumulation but did not alter UV irradiation- or N-acetyl-Leu-Leu-norleucinal-induced p53 accumulation. arsenite 70-78 P53 Homo sapiens 109-112 11103796-9 2000 p53 phosphorylation on serine 15 was also confirmed by immunoblotting technique in arsenite- and X-ray-treated HFW cells but was not observed in UV- or N-acetyl-Leu-Leu-norleucinal-treated HFW cells. arsenite 83-91 P53 Homo sapiens 0-3 11103796-10 2000 These results suggest the involvement of a phosphatidylinositol 3-kinase-related protein kinase in arsenite-induced p53 accumulation. arsenite 99-107 P53 Homo sapiens 116-119 8931502-2 1996 METHOD: A dexamethazone-inducible wt-p53 cDNA was introduced into two cervical carcinoma cell lines (TMCC-1 and ME180) and morphological changes were examined under a phase contrast microscope and following Papanicolaou staining. papanicolaou 207-219 P53 Homo sapiens 37-40 33824293-6 2021 Furthermore, ASP4132 treatment in NSCLC cells induced programmed necrosis, causing mitochondrial p53-cyclophilin D (CyPD)-adenine nucleotide translocase 1 (ANT1) association, mitochondrial depolarization and medium lactate dehydrogenase release. 4-(4-dimethylaminostyryl)-1-methylpyridinium 13-20 P53 Homo sapiens 97-100 11103796-13 2000 Together, these findings infer that arsenite-induced DNA strand breaks may lead to p53 phosphorylation and accumulation through an ataxia telangiectasia mutated-dependent pathway in HFW cells. arsenite 36-44 P53 Homo sapiens 83-86 11029509-7 2000 Tumor B18 exhibited two novel mutations in the p53 gene, ATGright curved arrow GTG (Metright curved arrow Val) at codon 237 and AATright curved arrow GAT (Asnright curved arrow Asp) at codon 263. Valine 106-109 P53 Homo sapiens 47-50 33808343-6 2021 Treatment of differentiated SH-SY5Y cells with 6-OHDA brought cell death, and specifically, apoptosis, which was significantly inhibited by the preincubation with MJe through caspase 3 blockage and the modulation of p53, Bax, and Bcl-2 genes. Oxidopamine 47-53 P53 Homo sapiens 216-219 9389053-4 1996 Comparison of these positive results of p53 gene mutation detected by silver staining method with the results by polymerase chain reaction-single strand conformation polymorphism analysis did not reveal matched results, especially during the precancerous period.

Fluoroquinolones 21-36 P53 Homo sapiens 68-71 9064332-6 1996 BA is also an efficient inhibitor of p53-dependent thymocyte apoptosis induced by DNA damage. Bongkrekic Acid 0-2 P53 Homo sapiens 37-40 12545812-5 2000 The results showed that the prevalence of p53 mutations in LSCC subjected to silver staining PCR-SSCP test were 50% (30/60) in exon 5, 11.67%(7/60) in exon 6, 41.6%(25/60) in exon 7, and 25%(15/60) in exon 8. Silver 77-83 P53 Homo sapiens 42-45 8764107-13 1996 Because these cell lines have the same p53 mutation, these findings suggest that there is a p53-independent G1-S checkpoint that mediates radiosensitization produced by fluorodeoxyuridine. Floxuridine 169-187 P53 Homo sapiens 92-95 33801507-2 2021 Previously, we demonstrated the ability of tryptophanol-derived polycyclic compounds to activate the tumor suppressor protein p53, a relevant therapeutic target in cancer. tryptophanol 43-55 P53 Homo sapiens 126-129 10953132-2 2000 MATERIALS AND METHODS: Immunohistochemical staining for p53 was semiquantitatively scored in archival formalin fixed, paraffin embedded tumor tissue obtained at diagnosis in 221 patients with prostate cancer.

Tacrolimus 143-153 P53 Homo sapiens 13-16 8787547-0 1996 Antioncogene P53 and mitogenic cytokine interleukin-8 aberrantly expressed in psoriatic skin are inversely regulated by the antipsoriatic drug tacrolimus (FK506). Tacrolimus 155-160 P53 Homo sapiens 13-16 8787547-8 1996 Interestingly, p53 transcription was clearly induced by FK506 treatment. Tacrolimus 56-61 P53 Homo sapiens 15-18 33236159-10 2021 Exome analyses following olaparib treatment identified de novo TP53 mutations, as well as increased frequencies of pre-existing TP53 mutations compared with the primary tumor. olaparib 25-33 P53 Homo sapiens 63-67 33236159-10 2021 Exome analyses following olaparib treatment identified de novo TP53 mutations, as well as increased frequencies of pre-existing TP53 mutations compared with the primary tumor. olaparib 25-33 P53 Homo sapiens 128-132 33236159-11 2021 In HCT116 TP53-/- cells carrying BRCA2 pathogenic mutations, TP53 inactivating mutations were associated with lower sensitivity to olaparib in vitro. olaparib 131-139 P53 Homo sapiens 61-65 33236159-12 2021 Thus, inactivating TP53 mutations may be associated to olaparib resistance in the presence of BRCA mutations. olaparib 55-63 P53 Homo sapiens 19-23 10953344-5 2000 In this study, we attempted to establish a polymerase chain reaction (PCR)-based assay for assessing the possibility of early detection of p53 mutation in archival Papanicolaou-stained cytologic sputum smears. papanicolaou 164-176 P53 Homo sapiens 139-142 8695259-1 1996 The expression of mutated p53 protein was studied in paraffin-embedded, formalin-fixed tumour specimens from 183 women with endometrial carcinoma.

Bongkrekic Acid 115-130 P53 Homo sapiens 74-77 8857671-4 1996 In this report, we present the effects of tumor suppressor p53 protein in tyrosinase gene expression and melanin synthesis in human melanoma. Melanins 105-112 P53 Homo sapiens 59-62 8857671-9 1996 These data suggest that in human melanoma p53 down-regulates the tissue-specific expression of tyrosinase gene and subsequent melanin synthesis. Melanins 126-133 P53 Homo sapiens 42-45 10857993-6 2000 Our results show that: 1) Sequential TPT --> G2/M-active drugs are synergistic when administration overlapped the maximum percentage of TPT-induced G2/M-phase cell arrest interval in all three mutated p53 cell lines; 2) the reverse sequential schedule (G2/M-active drug --> TPT) was antagonistic, and being only additive for Etoposide --> TPT association. Topotecan 37-40 P53 Homo sapiens 204-207 8711933-3 1996 In this study, we investigated the immunohistochemical expression of p53 in formalin fixed paraffin embedded archival specimens of 36 extrahepatic bile duct cancers in which p53 expression was found in eighteen (50%) cases.

Silver 68-74 P53 Homo sapiens 17-20 7490678-1 1995 A rapid non-isotopic PCR-SSCP (polymerase chain reaction-single-stranded conformation polymorphism) method was developed in this study to detect polymorphism and loss of heterozygosity (LOH) of p53 in formalin-fixed and paraffin-embedded samples of normal breast tissue and of breast cancer. Formaldehyde 201-209 P53 Homo sapiens 194-197 8771158-3 1995 Tumor p53 protein expression was detected by means of immunohistochemistry using the monoclonal antibody D07 on formalin fixed paraffin-embedded tissue sections. Formaldehyde 112-120 P53 Homo sapiens 6-9 7675452-0 1995 Geldanamycin selectively destabilizes and conformationally alters mutated p53. geldanamycin 0-12 P53 Homo sapiens 74-77 7675452-3 1995 We sought to examine whether geldanamycin, a drug capable of destabilizing several oncogene and proto-oncogene products, could alter the stability and DNA binding characteristics of several mutated p53 proteins. geldanamycin 29-41 P53 Homo sapiens 198-201 7672694-4 1995 In this study we examined 88 formalin-fixed paraffin-embedded clinical specimens of cervix for the presence of HPV and p53 expression.

Formaldehyde 178-186 P53 Homo sapiens 160-163 7556591-6 1995 Nuclear p53 immunoreactivity was assessed using a monoclonal antibody, DO-1, on Formalin-fixed paraffin-embedded specimens. Formaldehyde 80-88 P53 Homo sapiens 8-11 8529093-5 1995 The mdm-2 protein binds to both leucine-tryptophan residues at amino acids 22 and 23, from the amino terminal end of the protein, and in so doing, prevents all p53 functions. leucine-tryptophan 32-50 P53 Homo sapiens 160-163 7957681-5 1994 The ethylene glycol fraction contained a number of p53 binding proteins, and this fraction showed a DNA helicase activity measured by the displacement of DNA fragment from partially duplexed M13 DNA. Ethylene Glycol 4-19 P53 Homo sapiens 51-54 7530851-8 1994 Fixation-induced loss of p53 immunoreactivity was minimal for formalin (two of 10 tumors for one antibody each), more significant for Bouin (six of 10 tumors for one to five antibodies). Formaldehyde 62-70 P53 Homo sapiens 25-28 8036011-7 1994 It is evident that H2O2/FeCl3 possesses essentially the same mutagenic specificity for codons 249 and 250 of p53 as bulky carcinogens such as aflatoxin B1, benzo(a)pyrene or heterocyclic amines. heterocyclic amines 174-193 P53 Homo sapiens 109-112 21567003-10 1994 to-ether with other factors like p53 and nm23. to-ether 0-8 P53 Homo sapiens 33-36 8058709-8 1994 When bromodeoxyuridine was administered either in vivo (n = 93) or in vitro (n = 79), p53 accumulation was only marginally related to proliferative fraction (P = 0.067 by chi 2; P = 0.055 by Mann-Whitney).

Valine 61-67 P53 Homo sapiens 20-23 7549812-9 1995 Interestingly, we also found that p53 mutations occurred significantly more frequently in patients with a history of occupational exposure to asbestos [3 of 60 (5%) for patients without p53 mutations versus 5 of 25 (20%) of those with p53 mutations; P < 0.05]. Asbestos 142-150 P53 Homo sapiens 34-37 7549812-9 1995 Interestingly, we also found that p53 mutations occurred significantly more frequently in patients with a history of occupational exposure to asbestos [3 of 60 (5%) for patients without p53 mutations versus 5 of 25 (20%) of those with p53 mutations; P < 0.05].

Asbestos 142-150 P53 Homo sapiens 186-189 7750085-3 1995 Teleocidin antagonized both apoptosis and alterations of nuclear p53 protein and PCNA induced by these anticancer drugs. teleocidins 0-10 P53 Homo sapiens 65-68 7720110-3 1994 The result showed that mutation of both cell lines occurred on the 154th codon in exon5 of p53 gene, where GGC was displaced by GTC resulting a substitution of Val for Gly, nevertheless, N-ras oncogene and the exon7 of p53 gene are normal. Valine 160-163 P53 Homo sapiens 91-94 7720110-3 1994 The result showed that mutation of both cell lines occurred on the 154th codon in exon5 of p53 gene, where GGC was displaced by GTC resulting a substitution of Val for Gly, nevertheless, N-ras oncogene and the exon7 of p53 gene are normal. Valine 160-163 P53 Homo sapiens 219-222 7580888-2 1994 Sequences of the p53 gene have been obtained from DNA extracted from frozen and formalin-fixed paraffin-embedded cancer tissues. Formaldehyde 80-88 P53 Homo sapiens 17-20 8168507-7 1994 Using metal affinity chromatography, we have established that pure p53 binds the immobilised divalent ions Zn2+, Ni2+ and Co2+ with high affinity. Cobalt(2+) 122-126 P53 Homo sapiens 67-70 8139558-6 1994 Rodent cells transformed with E1A plus the p53(Val-135) temperature-sensitive mutant are transformed at the restrictive temperature and undergo rapid and complete apoptosis at the permissive temperature when p53 adopts the wild-type conformation.

Valine 47-50 P53 Homo sapiens 208-211 8176513-1 1994 Serum levels of p53 protein were examined in 23 cases of lung cancer (many with potential asbestos exposure), 23 unexposed matched hospital control subjects, 58 unmatched general population control subjects, and 4 people with nonmalignant lung disease using an enzyme-linked immunosorbent assay and Western immunoblotting. Asbestos 90-98 P53 Homo sapiens 16-19 8008749-1 1994 p53 expression in formalin-fixed, paraffin-embedded archival specimens of intrahepatic cholangiocarcinoma: retrieval of p53 antigenicity by microwave oven heating of tissue sections. Formaldehyde 18-26 P53 Homo sapiens 0-3 8008749-4 1994 We investigated expression of p53 in formalin-fixed, paraffin-embedded archival specimens of 40 CCs (22 autopsy cases and 18 surgical cases) by immunohistochemistry using four antibodies (PAb1801, DO-7, BP53-12, CM1). Formaldehyde 37-45 P53 Homo sapiens 30-33 8008749-10 1994 These results shows that a pretreatment of tissue sections by microwave oven heating is a very good method for demonstrating p53 protein in formalin-fixed, paraffin-embedded archival materials and that DO-7, BP53-12, and CM1 are useful antibodies for detection of p53 in formalin-fixed, paraffin-embedded archival materials. Formaldehyde 140-148 P53 Homo sapiens 125-128 8261448-5 1994 Forty-four % (16 of 36) of BCCs had a mutated p53 allele, usually opposite pyrimidine tracts, which is consistent with UV-induced mutations. pyrimidine 75-85 P53 Homo sapiens 46-49 7533993-3 1994 81.7% of AK, 100% of SCC, 73.8% of BCC as well as 29.2% of BEN, 37.5% of REH, and 26.9% of NE showed p53 positivity. benzamidine 59-62 P53 Homo sapiens 101-104 8112175-1 1993 Expression of P53 protein was detected immunohistochemically in formalin-fixed, paraffin-embedded tissues from 67 patients with bladder carcinoma and 6 normal bladder controls. Formaldehyde 64-72 P53 Homo sapiens 14-17 8325885-4 1993 The p53 mutants Val-135 and Phe-132 up-regulated IL-6 promoter activity in these cells at both 32.5 and 37 degrees C. The temperature-sensitive Val-135 mutant was not only not inhibitory or "wt-like" at the lower temperature, but had gained a transcriptional activator phenotype which was temperature-independent in HeLa cells. Valine 16-19 P53 Homo sapiens 4-7 8325885-4 1993 The p53 mutants Val-135 and Phe-132 up-regulated IL-6 promoter activity in these cells at both 32.5 and 37 degrees C. The temperature-sensitive Val-135 mutant was not only not inhibitory or "wt-like" at the lower temperature, but had gained a transcriptional activator phenotype which was temperature-independent in HeLa cells. Valine 144-147 P53 Homo sapiens 4-7 8325885-5 1993 The functional DNA target for transcriptional modulation of the IL-6 promoter by p53 species included the multiple cytokine- and second messenger-response element (-173 to -145); point mutations in the transcription factor C/EBP beta-binding site within the second messenger-response element largely blocked the ability of p53 mutants Val-135 and Phe-132 to up-regulate this promoter. Valine 335-338 P53 Homo sapiens 81-84 8325885-7 1993 In contrast, the p53 mutants Val-135 and Phe-132 further enhanced C/EBP beta-mediated up-regulation of IL-6 promoter constructs. Valine 29-32 P53 Homo sapiens 17-20 8415589-1 1993 The p53 gene was examined in a series of formalin-fixed paraffin-embedded astrocytic neoplasms of various types by polymerase chain reaction (PCR), single-strand conformation polymorphism analysis (SSCP), and direct sequencing of amplified DNA. Formaldehyde 41-49 P53 Homo sapiens 4-7 8390283-8 1993 The 12th mutation GTG-->GGG (valine-->glycine) at codon 216 was expressed in line SCC-12 clone B along with an apparently normal p53 allele and is to our knowledge a novel mutation. Valine 32-38 P53 Homo sapiens 135-138 8392521-3 1993 METHODS: The presence and localisation of the p53 protein in formalin fixed, paraffin wax embedded specimens of anal squamous epithelium (normal and neoplastic) was examined using immunohistochemical staining with a panel of two monoclonal antibodies (DO-1, DO-7) and one polyclonal antibody (CM-1). Formaldehyde 61-69 P53 Homo sapiens 46-49 8384406-1 1993 Striking differences were found between different histological types of breast cancer when 263 invasive breast carcinomas were tested for nuclear p53 accumulation in formaldehyde-fixed paraffin sections.

Formaldehyde 100-108 P53 Homo sapiens 0-3 1484319-2 1992 The object of this study was to examine the frequency of immunohistochemically detectable p53 overexpression in routinely processed, paraffin-embedded tissue from pleural mesotheliomas and from pleura showing reactive mesothelial hyperplasia, using a polyclonal antibody to formalin-resistant p53 epitopes, and to consider the diagnostic utility of this antibody in the distinction between mesothelioma and reactive mesothelium in pleural biopsy specimens. Formaldehyde 274-282 P53 Homo sapiens 90-93 1484319-6 1992 In conclusion, this study suggests that p53 immunostaining can help to distinguish epithelial or biphasic mesothelioma from reactive mesothelial hyperplasia in formalin-fixed, paraffin-embedded pleural biopsy specimens. Formaldehyde 160-168 P53 Homo sapiens 40-43 1358781-3 1992 Immunoreactive p53 was observed in the nuclei of tumor cells in 4% paraformaldehyde-fixed, frozen sections (12 of 15) and paraffin-embedded sections (11 of 15), but not in routinely processed (10% formalin-fixed) specimens.

Formaldehyde 46-54 P53 Homo sapiens 39-42 1918170-4 1991 We previously identified a case of human acute myelogenous leukemia (AML) in which both alleles of the p53 gene had undergone independent missense mutations (at codons 135 cys to ser and 246 met to val). Valine 198-201 P53 Homo sapiens 103-106 2137009-1 1990 p53 messenger RNA expression was examined using a cDNA probe in 76 fresh primary breast tumour specimens, 15 of which came from patients treated with toxoxifen prior to surgery. toxoxifen 150-159 P53 Homo sapiens 0-3 33773191-0 2021 Bibenzyl analogue DS-1 inhibits MDM2-mediated p53 degradation and sensitizes apoptosis in lung cancer cells.

Cocaine 70-77 P53 Homo sapiens 138-141 34417893-8 2021 Further analysis revealed that PARylation of p53 by cocaine treatment resulted in nuclear accumulation of p53. Cocaine 52-59 P53 Homo sapiens 45-48 34417893-8 2021 Further analysis revealed that PARylation of p53 by cocaine treatment resulted in nuclear accumulation of p53. Cocaine 52-59 P53 Homo sapiens 106-109 34417893-10 2021 Interestingly, cocaine-induced p53 PARylation resulted in the induction of proline oxidase (POX)-a p53 responsive gene involved in cellular metabolism. Cocaine 15-22 P53 Homo sapiens 31-34 34417893-11 2021 Given that cocaine-induced p53 PARylation is an energy-dependent process, we observed that cocaine-induced PARP-1/p53/POX axes alters cellular energy metabolism. Cocaine 11-18 P53 Homo sapiens 27-30 34417893-11 2021 Given that cocaine-induced p53 PARylation is an energy-dependent process, we observed that cocaine-induced PARP-1/p53/POX axes alters cellular energy metabolism. Cocaine 11-18 P53 Homo sapiens 114-117 34417893-11 2021 Given that cocaine-induced p53 PARylation is an energy-dependent process, we observed that cocaine-induced PARP-1/p53/POX axes alters cellular energy metabolism. Cocaine 91-98 P53 Homo sapiens 27-30 34343636-8 2021 The AKT1/FOXP3 axis mediated the CerS6 expression and promoted p53 mutant pancreatic tumorigenesis by producing excessive C16-ceramide, which induced the accumulation of mutant p53. N-palmitoylsphingosine 122-134 P53 Homo sapiens 63-66 34343636-8 2021 The AKT1/FOXP3 axis mediated the CerS6 expression and promoted p53 mutant pancreatic tumorigenesis by producing excessive C16-ceramide, which induced the accumulation of mutant p53. N-palmitoylsphingosine 122-134 P53 Homo sapiens 177-180 34850229-8 2022 MON 52276 and glyphosate altered the expression of genes in liver reflecting TP53 activation by DNA damage and circadian rhythm regulation. mon 52276 0-9 P53 Homo sapiens 77-81 34680379-10 2021 Lastly, vemurafenib-resistant melanoma cells showed an altered expression of p53 and p73 isoforms, namely an increased expression of potentially pro-oncogenic Delta40p53beta and a decrease in tumor-suppressive TAp73beta.

Ascorbic Acid 0-9 P53 Homo sapiens 73-77 34497762-10 2021 Collectively, these data suggest that ascorbate could exert a beneficial anti-proliferative effect on AML cells harboring both TET2 and TP53 mutations whilst not interfering with targeted cytotoxic therapies such as Prima-1Met. Ascorbic Acid 38-47 P53 Homo sapiens 136-140 34338098-9 2022 Thus, we summarized some of the sterol-related signaling pathways in glioma and how they can be associated with other signaling pathways, including EGFR/PI3K/Akt/mTOR, P53, and retinoblastoma protein. Sterols 32-38 P53 Homo sapiens 168-171 34377229-5 2021 This finding suggests that both KrasG12V and KrasG12D are required for showing higher FL118 efficacy, while the presence of KrasG13D could somehow decrease FL118 efficacy under the defined p53/APC genetic status. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione 156-161 P53 Homo sapiens 189-192 34377229-10 2021 These findings would be useful for predicting FL118 sensitivity to patients" CRC tumors with the defined Kras mutation subtypes under the defined p53/APC genetic status. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione 46-51 P53 Homo sapiens 146-149 35460941-0 2022 Low doses of niclosamide and quinacrine combination yields synergistic effect in melanoma via activating autophagy-mediated p53-dependent apoptosis. Quinacrine 29-39 P53 Homo sapiens 124-127 35460941-5 2022 The results showed, briefly, an exposure to niclosamide and quinacrine led to an increased apoptosis-related protein p53, cleaved caspase-3 and cleaved PARP and autophagy-related protein LC3B expression, and a decreased expression of autophagy-related protein p62, finally leading to cell apoptosis and autophage. Quinacrine 60-70 P53 Homo sapiens 117-120 35217253-8 2022 Biotin-C3 peptide characterized luminal BC according to p53 status and to HER2 expression, being the biosensor a better strategy when compared to ELISA test. Phenobarbital 32-39 P53 Homo sapiens 56-59 35189247-4 2022 Out of these, the most prominent genetic alterations (PRKAR-1A, CTNNB1, ZNRF3, TP53, CCNE1 and TERF2 genes) are linked with a glycolytic enzyme pyruvate kinase M2 (PKM2), which converts phosphoenolpyruvate (PEP) to pyruvate in the glycolytic pathway. Phosphoenolpyruvate 186-205 P53 Homo sapiens 79-83 35626649-6 2022 Here, we employed the prime editing tool to revert a TP53 missense C > T mutation (L194F) in a T47D luminal A breast cancer cell line.

Iodine 68-74 P53 Homo sapiens 187-191 35085581-0 2022 Piperlongumine induces ROS mediated apoptosis by transcriptional regulation of SMAD4/P21/P53 genes and synergizes with doxorubicin in osteosarcoma cells. piperlonguminine 0-14 P53 Homo sapiens 89-92 35085581-7 2022 Piperlongumine treatment significantly upregulated the expression of genes BAX, P21, P53, and SMAD4; while the BCL-2, SURVIVIN, TNFA, and NFKB genes expression was found down-regulated. piperlonguminine 0-14 P53 Homo sapiens 85-88 35209068-7 2022 The expression of tumor protein p53 and microphthalmia-associated transcription factor and tyrosinase activity decreased in response to HQ, PDRN, and PVN, and this decrease was accompanied by decreased melanin content in the skin. Melanins 202-209 P53 Homo sapiens 32-35 35211418-4 2022 Longitudinal analysis before and after fludarabine based on NGS sequencing demonstrated that low-burden TP53 mutations were present before the onset of treatment and expanded at relapse to become the predominant clone. fludarabine 39-50 P53 Homo sapiens 104-108 35012638-7 2022 Based on recent reports of frequent defects in the homologous recombination (HR) pathway in EC, we assessed mutational signatures and HR deficiency scores and correlated these with in vivo responses to the PARP inhibitor (PARPi) talazoparib in six PDXs representing the copy number high/p53-mutant and mismatch-repair deficient molecular subtypes of EC. talazoparib 229-240 P53 Homo sapiens 287-290 33905708-6 2021 RESULTS: Heme supports carcinogenesis via modulation of immune cell function, promoting inflammation and gut dysbiosis, impeding tumour suppressive potential of P53 gene, promoting cellular cytotoxicity and reactive oxygen species generation and modulating Nfr2 /HO-1 axis. Heme 9-13 P53 Homo sapiens 161-164 3025664-10 1986 This sequence difference resulted in an arginine being coded for in clone p53-H-1 and a proline being coded for at the equivalent position in clone p53-H-19. Proline 88-95 P53 Homo sapiens 148-151 33932899-8 2021 In human podocyte, inhibition of AGE formation by pyridoxamine prevented miR-34a dependent repression of SIRT1, p53 acetylation and activate podocyte autophagy in a dose-dependent manner. Pyridoxamine 50-62 P53 Homo sapiens 112-115 33965112-8 2021 Celastrol and Fe3O4/alpha-Fe2O3/CA-PEG-celastrol increased the production of reactive oxygen species in SMMC-7721 cells and promoted apoptosis and apoptosis-related proteins (p53, Bax, Bcl-2) were also changed. alpha-fe2o3 20-31 P53 Homo sapiens 175-178 34039253-7 2021 Considering the important role played by MAPK and p53 signaling pathways in cell-cycle arrest, we explored their potential involvement in STE-induced cell-cycle arrest by using specific inhibitors. Sterigmatocystin 138-141 P53 Homo sapiens 50-53 34039253-8 2021 The inhibition of JNK and ERK resulted to attenuate S and G2/M arrest, whereas the inhibition of p38 and p53 attenuated only STE-induced S phase arrest. Sterigmatocystin 125-128 P53 Homo sapiens 105-108 34039253-9 2021 In conclusion, the present study demonstrates that STE induced DNA damage and triggered MAPK and p53 pathways activation, resulting in cell-cycle arrest at the S and the G2/M phase. Sterigmatocystin 51-54 P53 Homo sapiens 97-100 32480415-8 2021 Interestingly, patients with mutated allele rs1229984 in ADH1B had lower level of signature J while mutated allele rs671 in ALDH2 exhibited higher signature J abundance, suggesting acetaldehyde is one cause of signature J. Intriguingly, somatic mutations of three potential cancer driver genes (TP53, CUL3 and NSD1) were found the critical contributors for increased mutational load of signature J in alcohol consumption patients. Acetaldehyde 181-193 P53 Homo sapiens 295-299 34004477-8 2021 gamma-Fe2O3 and Fe3O4 NPs could also cause mitochondrial fusion and fission dysregulation, activate lipid peroxidation and iron metabolism-related genes in a P53-dependent manner. gamma-fe2o3 0-11 P53 Homo sapiens 158-161 33987018-15 2021 Western blot results revealed that the expression of p53, p27, p21, CDK4, cyclin D1, CDK2, cyclin E, pRb, E2F1 and c-myc decreased after CENPN knockdown, but there was no significant change in total Rb levels. Rubidium 102-104 P53 Homo sapiens 53-56 33858805-0 2021 Expression of p53 is associated with microbial acetaldehyde production in oralsquamous cell carcinoma. Acetaldehyde 47-59 P53 Homo sapiens 14-17 33858805-1 2021 OBJECTIVES: The objective of this study was to investigate the association between p53 expression and microbial acetaldehyde production in patients with oral squamous cell carcinoma (OSCC).

Overexpression of p53 was observed in a time-dependent manner, along with a decrease in the Bcl-2/Bax ratio. Fenretinide 193-204 P53 Homo sapiens 233-236 17182797-9 2007 The caspase-8 inhibitor Z-IETD-FMK attenuated the DIM-induced apoptosis, indicating that increased activation of this enzyme contributed to the increase in p53-independent apoptosis that was observed in colon cancer cells. benzyloxycarbonyl-isoleucyl-glutamyl-threonyl-aspartic acid fluoromethyl ketone 24-34 P53 Homo sapiens 156-159 17050806-0 2007 Zoledronic acid activates the DNA S-phase checkpoint and induces osteosarcoma cell death characterized by apoptosis-inducing factor and endonuclease-G translocation independently of p53 and retinoblastoma status.

Zoledronic Acid 11-26 P53 Homo sapiens 136-139 17170001-2 2007 Comparing p53 and p73beta proteins, our data show that zinc chelation by EDTA is significantly more detrimental to the ability of p73beta than of p53 to bind DNA, most likely due to the greater effect that the loss of zinc has on the conformation of the DNA-binding domain of p73. Edetic Acid 73-77 P53 Homo sapiens 10-13 17170001-2 2007 Comparing p53 and p73beta proteins, our data show that zinc chelation by EDTA is significantly more detrimental to the ability of p73beta than of p53 to bind DNA, most likely due to the greater effect that the loss of zinc has on the conformation of the DNA-binding domain of p73.

Selenomethionine 0-16 P53 Homo sapiens 56-59 17100737-3 2006 Selenium protects cells from UVB-induced cell death and apoptosis by mechanisms which are unclear, although recent reports suggest that selenium protects against UV-induced cell damage by inducing DNA repair enzymes and transactivating p53. Selenium 136-144 P53 Homo sapiens 236-239 17100737-4 2006 METHODS: We examined whether selenomethionine could protect human skin cells from UV radiation-induced p53 transactivation, using a pRGCDeltafos-lacZ p53-dependent reporter construct stably transfected in an amelanotic melanoma cell line (Arn-8) which expresses wild-type p53.

Selenomethionine 25-41 P53 Homo sapiens 108-111 17100737-7 2006 Treatment with 50 microM selenomethionine for 24 h both pre- and post-irradiation, significantly diminished p53 activation by 30-43% across the UV dose range (P=0.0085, n=5 independent experiments) and decreased UV-induced p53 protein accumulation as assessed by Western blotting. Selenomethionine 25-41 P53 Homo sapiens 223-226 17100737-8 2006 CONCLUSIONS: We conclude that selenomethionine inhibits broad band UVB-induced p53 transactivation and protein accumulation and that this effect correlates with reported protective effects of selenium against UV-induced DNA damage.

Proline 92-95 P53 Homo sapiens 8-12 16648559-9 2006 However, a larger population of senescence-activated beta-galactosidase-positive cells was seen in IUdR/methoxyamine/ionizing radiation-treated cells, which was correlated with the increased activation of the senescence factors p53 and pRb. methoxyamine 104-116 P53 Homo sapiens 228-231 16206288-6 2006 In vitro treatment with butyrate or propionic acid, but not succinic acid, elicited a positive response in the p53-p53R2 system. propionic acid 36-50 P53 Homo sapiens 111-114 16206288-7 2006 Moreover, p53-dependent DNA repair, investigated by radioactive nucleotide incorporation, was induced by butyric acid and inhibited by short-interfering p53 and p53R2 RNAs. Butyric Acid 105-117 P53 Homo sapiens 10-13 16206288-8 2006 Therefore, it was concluded that the p53-p53R2-dependent DNA repair system is constitutively stimulated by butyric acid, which accumulates in UC inflammatory lesions.

Proline 97-104 P53 Homo sapiens 279-282 16498444-3 2006 The identification of a new family of proteins, known as ASPPs (ankyrin-repeat-, SH3-domain- and proline-rich-region-containing proteins), has led to the discovery of a novel mechanism that selectively regulates the apoptotic function, but not the cell-cycle-arrest function, of p53, and gives an insight into how p53 responds to different stress signals. Proline 97-104 P53 Homo sapiens 314-317 16251187-3 2006 To identify an oxidized lipid that induces p53 phosphorylation, we conducted a screening of lipid peroxidation products in human neuroblastoma SH-SY5Y cells and identified 4-oxo-2-nonenal (ONE), a recently identified aldehyde originating from the peroxidation of omega6 polyunsaturated fatty acids, as a potential inducer of the p53 phosphorylation. 4-oxo-2-nonenal 172-187 P53 Homo sapiens 329-332 16251187-3 2006 To identify an oxidized lipid that induces p53 phosphorylation, we conducted a screening of lipid peroxidation products in human neuroblastoma SH-SY5Y cells and identified 4-oxo-2-nonenal (ONE), a recently identified aldehyde originating from the peroxidation of omega6 polyunsaturated fatty acids, as a potential inducer of the p53 phosphorylation. omega6 polyunsaturated fatty acids 263-297 P53 Homo sapiens 43-46 16326430-9 2005 The levels of p53, bcl-2, and 8-OHdG were concomitantly changed by alcohol and acetaldehyde treatment in midbrain cells. Acetaldehyde 79-91 P53 Homo sapiens 14-17 16362078-4 2005 DHC exposure in the human TK6 lymphoblastoid cell line also caused concentration-dependent increases in p53 acetylation and cytotoxicity. 3,4-dihydrocoumarin 0-3 P53 Homo sapiens 104-107 16362078-6 2005 Thus, DHC inhibits both yeast Sir2p and human SIRT1 deacetylases and increases p53 acetylation and apoptosis, a phenotype associated with senescence and aging. 3,4-dihydrocoumarin 6-9 P53 Homo sapiens 79-82 16307686-2 2005 Furthermore, the polymorphism at codon 72 (encoding either arginine or proline) of the p53 tumor-suppressor gene is discussed as a possible determinant for cancer risk.

Tetracycline 61-73 P53 Homo sapiens 85-88 16120440-3 2005 Conditional expression of wild-type p53 protein upon withdrawal of tetracycline was accompanied with increased expression of p21(WAF1/Cip1) resulting in reduced cell proliferation. Tetracycline 67-79 P53 Homo sapiens 36-39 15905205-7 2005 Importantly, patient survival did significantly differ: those patients having a TP53 mutation on the proline allele had the worst survival outcomes (hazards ratio = 2.6, P < 0.03). Proline 101-108 P53 Homo sapiens 80-84 15905205-9 2005 Our data suggest that there are selective pressures for loss of the TP53 proline allele in non-small cell lung cancer.

Proline 17-24 P53 Homo sapiens 4-7 18003626-5 2008 Two cell models were selected: 041 TR fibroblasts in which the expression of p53 is regulated by a tetracycline-inducible promoter, and WI38 primary lung fibroblasts together with their isogenic derivative VA13, in which p53 is abrogated post-translationally by SV40 transformation. Tetracycline 99-111 P53 Homo sapiens 77-80 22735455-7 2012 These PIMT effects on p53 stability and activity are attributed to the PIMT-mediated methylation of p53 at isoaspartate residues 29 and 30. Isoaspartic Acid 107-119 P53 Homo sapiens 100-103 16179969-1 2005 We recently identified two thiazolidin compounds, 5-[(4-methylphenyl)methylene]-2-(phenylamino)-4(5H)-thiazolone (MMPT) and 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidin (DBPT), that inhibit the growth of human non-small-cell lung and colon cancer cells independent of P-glycoprotein and p53 status. 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidin 124-184 P53 Homo sapiens 303-306 22717582-4 2012 In proof-of-principle studies, betulinic acid, doxorubicin and vincristine induced cell death in a p53- and NOXA-independent pathway involving mitochondrial pore formation, release of cytochrome c and caspase activation. Vincristine 63-74 P53 Homo sapiens 99-102 16140998-8 2005 CONCLUSIONS: The p53 codon 72 Arg/Pro polymorphism is not associated with age of onset or severity of glaucoma. Proline 34-37 P53 Homo sapiens 17-20 16107721-9 2005 In addition, depolarization of the mitochondrial membrane by mitochondrial inhibitors such as rotenone or antimycin A led colorectal cancer cells into p53-dependent senescence. Rotenone 94-102 P53 Homo sapiens 151-154 18612219-1 2008 BACKGROUND: The p53 codon 72 polymorphism, which results in either an arginine or proline residue, plays a different role in vitro and in vivo in cell survival and drug resistance. Proline 82-89 P53 Homo sapiens 16-19 22717582-5 2012 In contrast, when betulinic acid was combined with either doxorubicine or vincristine, cell death signaling changed considerably; the drug combinations clearly depended on both p53 and NOXA.

Butyric Acid 107-122 P53 Homo sapiens 8-11 15688418-2 2005 Sodium butyrate (NaB), a histone deacetylase inhibitor, has been shown to cause a G(1) cell cycle arrest by inducing p21(WAF1/CIP1) in a p53-independent manner. Butyric Acid 0-15 P53 Homo sapiens 137-140 18089834-7 2007 p53 activation occurs at a posttranslational level via chloroquine-dependent phosphorylation of the checkpoint protein kinase, ataxia telangiectasia-mutated (ATM), leading to ATM-dependent phosphorylation of p53.

Dicumarol 68-78 P53 Homo sapiens 161-164 22074401-11 2012 In p53(-/-) and p53 mutant cells, GaQ(3) -induced Ca(2+) -signalling generated ROS. tris(8-quinolinolato)gallium (III) 35-41 P53 Homo sapiens 17-20 22517433-7 2012 In contrast, pre-incubation of p53-mutant cells with tenovin-6 or leptomycin B reduces the efficacy of vinca alkaloids, suggesting that these p53 activators could be effective as chemoprotectants if combined with S- but not M-phase poisons. Vinca Alkaloids 103-118 P53 Homo sapiens 31-34 15846102-6 2005 We then injected Ad-p53 into subcutaneous tumors of KATO-III and HuH7 combined with intraperitoneal administration of SB and found a significantly higher growth suppressive effect than single treatments of each. Butyric Acid 118-120 P53 Homo sapiens 20-23 15846102-10 2005 This was further supported by the finding that BAI-1 (brain specific angiogenesis inhibitor-1), an inhibitor of vascularization, was induced by SB treatment in KATO-III and HuH7 cells transfected with Ad-p53. Butyric Acid 144-146 P53 Homo sapiens 204-207 15846102-11 2005 Thus SB was shown to be an efficient potentiator of p53 gene therapy for cancer.

Vinca Alkaloids 103-118 P53 Homo sapiens 142-145 17906639-5 2007 Accordingly, tumor-associated mutations at Pin1-binding residues within the p53 proline-rich domain hamper acetylation of p53 by p300. Proline 80-87 P53 Homo sapiens 122-125 15733860-1 2005 In this study, we demonstrated that Ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F) had stronger cytotoxicity against MKN-45, a gastric cancer cell line bearing wild-type p53 than MKN-28, another gastric cancer cell line containing missense mutation in p53. ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid 36-85 P53 Homo sapiens 178-181 22521640-0 2012 WITHDRAWN: Hexavalent chromium induces premature senescence through reactive oxygen species-mediated p53 pathway in L-02 hepatocytes. Chromium 22-30 P53 Homo sapiens 101-104 15733860-1 2005 In this study, we demonstrated that Ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F) had stronger cytotoxicity against MKN-45, a gastric cancer cell line bearing wild-type p53 than MKN-28, another gastric cancer cell line containing missense mutation in p53. ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid 36-85 P53 Homo sapiens 260-263 15686411-11 2005 On the other hand, the results showed that acacetin-induced apoptosis was accompanied by up-regulation of Bax and p53, down-regulation of Bcl-2, and cleavage of Bad. acacetin 43-51 P53 Homo sapiens 114-117 17685632-5 2007 Western blot data revealed that gallic acid stimulated an increase in the protein expression of Fas, FasL, and p53. Gallic Acid 32-43 P53 Homo sapiens 111-114 17113707-9 2007 Present findings indicate occurrence of sensitization to cisplatin by zoledronic acid in wild-type p53 osteosarcoma cells but not in p53-null cells nor in cells expressing a dominant-negative form of p53, supporting that wild-type p53 is required for synergistic interaction of cisplatin and zoledronic acid. Zoledronic Acid 70-85 P53 Homo sapiens 99-102 22262850-5 2012 Herein, we describe the preparation and characterization of an oligodeoxynucleotide containing a CPD of a T(m)CG site, one of the major sites of C methylation and C-to-T mutations found in the p53 gene of basal and squamous cell cancers. cysteinylglycine 110-112 P53 Homo sapiens 193-196 17428792-5 2007 Using potent PARP inhibitors and PARP-1 knock-out cells, we demonstrate a functional interplay between ATM and poly(ADP-ribose) that is important for the phosphorylation of p53, SMC1, and H2AX. Poly Adenosine Diphosphate Ribose 111-127 P53 Homo sapiens 173-176 16285571-3 2005 These experiments led us to identify ingenol-20-benzoate (11) as a promising antitumour compound characterized by a relevant inhibition of cell growth and apoptotic cell death involving a p53-mediated pathway. ingenol-20-benzoate 37-56 P53 Homo sapiens 188-191 22223356-8 2012 These results suggest that aluminium is not generically mutagenic, but similar to an activated oncogene, it induces proliferation stress, DSBs and senescence in normal mammary epithelial cells; and that long-term exposure to AlCl(3) generates and selects for cells able to bypass p53/p21(Waf1) -mediated cellular senescence. Aluminum 27-36 P53 Homo sapiens 280-283 15638997-0 2005 Microarray analysis of bicalutamide action on telomerase activity, p53 pathway and viability of prostate carcinoma cell lines. bicalutamide 23-35 P53 Homo sapiens 67-70 15638997-4 2005 Response to bicalutamide in LNCaP cells was represented by downregulation of androgen-regulated genes, activation of the p53 pathway and inhibition of telomerase, which was associated with downregulation of v-myc avian myelocytomatosis viral oncogene homologue (MYC) and telomerase reverse transcriptase subunit. bicalutamide 12-24 P53 Homo sapiens 121-124 15638997-6 2005 In conclusion, we provide an explanation for telomerase inhibition after androgen receptor blockade in LNCaP cells and we also report activation of the p53 pathway in LNCaP cells and in-vitro sensitivity to bicalutamide of low confluent androgen-insensitive DU145 cells. bicalutamide 207-219 P53 Homo sapiens 152-155 15638997-8 2005 In particular, activation of the p53 pathway after treatment with 80 microM bicalutamide could justify usage of bicalutamide dosages higher than 150 mg daily in androgen-sensitive carcinoma therapy. bicalutamide 76-88 P53 Homo sapiens 33-36 17631738-7 2007 All of the RA patients and controls were genotyped by the polymerase chain reaction and allele-specific oligonucleotide techniques for p53 gene polymorphism Arg/Pro at codon 72.

Proline 150-153 P53 Homo sapiens 6-10 17599946-1 2007 A TP53 gene polymorphism, resulting in an arginine (R) to proline (P) at codon 72 (TP53 R72P), has been associated with the susceptibility to various cancers.

Proline 80-87 P53 Homo sapiens 34-37 17406354-2 2007 Considering that cancer cells are harboured in a hypoxic environment in vivo, we here tested the hypothesis that the p53 codon 72 proline allele confers a survival disadvantage in presence of hypoxia. Proline 130-137 P53 Homo sapiens 117-120 17406354-3 2007 Here, we show that the transient transfection of the proline allele in p53 null cancer cells exposed to low oxygen tension or to the hypoxia-mimetic drug Desferoxamine induces a higher amount of cell death than the arginine allele. Proline 53-60 P53 Homo sapiens 71-74 17406354-6 2007 These data indicate that the p53 codon 72 proline allele is less permissive for the growth of cancer cells in a hypoxic environment, and suggest that the preferential retention of the arginine allele in the tumour tissues of arginine/proline heterozygous patients may depend upon its lowered capacity to induce cell death in a hypoxic tumour environment.

Rubidium 83-85 P53 Homo sapiens 99-102 21943426-8 2011 Further local structure analyses revealed that, guided by all-atom MD ensemble of fragments, the p53 N-terminal domain ensemble was biased to kinked structures in the AD1 region and biased to extended conformers in a proline-rich region and these biases contributed to improvement of the reproduction of the experiments.

Fenretinide 78-89 P53 Homo sapiens 264-268 19064630-6 2009 To better understand the mechanism by which PUVA treatment induces p53, we exposed human skin fibroblasts with PUVA under conditions that differentially produce monoadducts and ICLs and found that psoralen-induced ICLs induced phosphorylation of the Ser-15 site of p53 and apoptosis much more effectively than psoralen-induced monoadducts. ser-15 250-256 P53 Homo sapiens 67-70 11716435-8 2000 At an ASO concentration of 300 nM, p53 protein was induced 12.5-fold and p21 was induced 8-fold over background levels, 24 h after start of ASO treatment.

Selenium 136-144 P53 Homo sapiens 212-215 10998350-8 2000 However, when cells were simultaneously treated with PDTC and actinomycin D, p53 accumulated in both the nucleus and the cytoplasm.

Dactinomycin 96-109 P53 Homo sapiens 0-3 17172419-6 2006 Previously, we have shown that irofulven activates ATM and its targets, NBS1, SMC1, CHK2, and p53. irofulven 31-40 P53 Homo sapiens 94-97 16798066-6 2006 o-PD and Cl-PD caused piperidine-labile and formamidopyrimidine-DNA glycosylase-sensitive lesions at cytosine and guanine residues respectively in the 5"-ACG-3" sequence, complementary to codon 273, a well-known hotspot of the human p53 tumor suppressor gene. formamidopyrimidine 44-63 P53 Homo sapiens 233-236 17094395-1 2006 BACKGROUND: The oncoprotein E6 binds to and degrades the p53 tumor suppressor protein, with different efficacy depending on the p53 codon 72 (arg/pro) polymorphism. Proline 20-23 P53 Homo sapiens 57-60 17094395-1 2006 BACKGROUND: The oncoprotein E6 binds to and degrades the p53 tumor suppressor protein, with different efficacy depending on the p53 codon 72 (arg/pro) polymorphism. Proline 20-23 P53 Homo sapiens 128-131 16966095-2 2006 Using a model cell line in which p53 expression is regulated exogenously in a tetracycline-off system (TR9-7 cells) , our laboratory has shown that arsenite disrupts mitosis and that p53-deficient cells [p53(-)], in contrast to p53-expressing cells [p53(+)], display greater sensitivity to arsenite-induced mitotic arrest and apoptosis.

Leflunomide 16-27 P53 Homo sapiens 210-213 16906043-4 2006 Whole blood (part 1+2) was stimulated (24 hr) with eight different concentrations of actinomycin-D (0-800 nM), an apoptosis inductor acting via p53-pathway. Dactinomycin 85-98 P53 Homo sapiens 144-147 10570149-7 1999 Substitution of Ser-20 was sufficient to abrogate p53 stabilization in response to both IR and UV light. ser-20 16-22 P53 Homo sapiens 50-53 10597242-6 1999 Inhibition of transcription by Actinomycin D blocks both KILLER/DR5 and p21 induction in cells undergoing p53-dependent apoptosis.

Tetracycline 153-165 P53 Homo sapiens 48-51 10567774-5 1999 Such p53-independent cytotoxicity of olomoucine was also confirmed in other human Burkitt"s lymphoma and lymphoid cell lines containing wild-type and mutant p53. olomoucine 37-47 P53 Homo sapiens 5-8 10567774-5 1999 Such p53-independent cytotoxicity of olomoucine was also confirmed in other human Burkitt"s lymphoma and lymphoid cell lines containing wild-type and mutant p53. olomoucine 37-47 P53 Homo sapiens 157-160 10567774-6 1999 Therefore, our results give an impetus to continued research into olomoucine that might be a very useful chemotherapeutic strategy in the treatment of patients with mutant p53 tumors, at least in lymphoma patients. olomoucine 66-76 P53 Homo sapiens 172-175 16624812-3 2006 To further understand how excess HDM2 regulates p53-mediated functions, we generated H1299 cell clones that constitutively express both ectopic HDM2 and tetracycline-regulated inducible p53.

Dactinomycin 44-57 P53 Homo sapiens 91-94 16981429-0 2006 The inhibitory action of long-chain fatty acids on the DNA binding activity of p53. long-chain fatty acids 25-47 P53 Homo sapiens 79-82 10449610-1 1999 A polymorphism at codon 72 of the p53 gene, resulting in either an arginine or a proline residue in the protein, has been reported to affect the susceptibility of p53 to human papillomavirus (HPV) E6-mediated degradation in cultured cells. Proline 81-88 P53 Homo sapiens 34-37 10449610-1 1999 A polymorphism at codon 72 of the p53 gene, resulting in either an arginine or a proline residue in the protein, has been reported to affect the susceptibility of p53 to human papillomavirus (HPV) E6-mediated degradation in cultured cells. Proline 81-88 P53 Homo sapiens 163-166 9707426-6 1998 To explain this discrepancy, evidence is given for a proline-rich domain-mediated cellular activation of p53 DNA binding. Proline 53-60 P53 Homo sapiens 105-108 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Proline 51-54 P53 Homo sapiens 47-50 10473656-10 1999 The results in KS, as compared with K562, confirm that wild-type p53 can prevent further cycling of polyploid cells by blocking rereplication. Potassium 15-17 P53 Homo sapiens 65-68 10582657-15 1999 Induction of p53 levels was observed in WHCO3 cells exposed to GLA, AA, PGA2, indomethacin and the combination of indomethacin and GLA or AA. Indomethacin 114-126 P53 Homo sapiens 13-16 9658131-2 1998 Oligomerization, intact DNA-binding, replication protein A-binding, and proline-rich domains of the p53 protein were essential for efficient inhibition, while the N-terminal transcriptional activation and C-terminal regulatory domains were dispensable for the suppressor activity of the p53 protein. Proline 72-79 P53 Homo sapiens 100-103 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Proline 55-58 P53 Homo sapiens 47-50 10467417-5 1999 Using a series of point and deletion mutants of p53 under the control of tetracycline-regulated promoter we show that certain mutants, like the wild type, protect cells at low levels but lead to apoptosis when overexpressed. Tetracycline 73-85 P53 Homo sapiens 48-51 9690520-3 1998 Here we report that exposure of macrophages to lipopolysaccharide/interferon-gamma or lipophilic cAMP analogs such as dibutyryl-cAMP or 8-bromo-cAMP for 15 h attenuated DNA fragmentation and accumulation of the tumor suppressor p53 in response to the chemotherapeutic agents cisplatin and etoposide, compared to cells that received chemotherapeutic agents only. Bucladesine 118-132 P53 Homo sapiens 228-231 16697770-9 2006 Higher ORs for COPD were seen for persons with p53 Pro/Pro or Pro/Arg genotypes against Arg/Arg genotype [OR = 2.35, 95% CI 1.27-4.39, P = 0.008], or p21 Arg/Arg and Arg/Ser genotypes against Ser/Ser genotype [OR = 2.07, 95% CI 1.06-4.05, P = 0.033]. Proline 55-58 P53 Homo sapiens 47-50 10432310-1 1999 The ability to separate the isoforms of human tumour suppressor protein p53 expressed in insect cells using heparin-Sepharose correlates with differences in the isoelectric point of p53, demonstrating that p53 can be heterogeneously modified and providing support for the use of insect cells as a model system for identifying novel signalling pathways that target p53. Sepharose 116-125 P53 Homo sapiens 72-75 16364678-5 2006 The Streptavidin-biotin method of immunohistochemistry was used for the staining with p53 and Ki67 in 22 cases of OLP and 27 cases diagnosed as OLL. Biotin 17-23 P53 Homo sapiens 86-89 10403534-0 1999 Differential apoptosis by indomethacin in gastric epithelial cells through the constitutive expression of wild-type p53 and/or up-regulation of c-myc. Indomethacin 26-38 P53 Homo sapiens 116-119 10682599-0 1998 [Mutation of p53 gene in human fetal gastric mucosal cells by sterigmatocystin in vitro]. Sterigmatocystin 62-78 P53 Homo sapiens 13-16 16518417-4 2006 On the other hand, pretreatment with dicoumarol enhanced cytotoxicity of CDDP in three cell lines with wild type of p53 (RT112, 253J and LNCap), but not in three other cell lines with mutant p53 or in RT112 stable transfectants with a dominant-negative mutant of p53. Dicumarol 37-47 P53 Homo sapiens 191-194 16518417-5 2006 In RT112 and LNCap, CDDP induced p53 and p21 expression, while pretreatment of dicoumarol suppressed induction of p53/p21 and resulted in sequential activation of c-Jun N-terminal kinase (JNK) in a time-dependent manner. Dicumarol 79-89 P53 Homo sapiens 114-117 9563901-1 1998 In the present study, we report our findings on the impact of p53 disruption on the sensitivity of human cell lines to the antimitotic agents Taxol and vincristine. Vincristine 152-163 P53 Homo sapiens 62-65 10347180-4 1999 The yeast two-hybrid and in vitro binding analyses revealed that necdin bound to a narrow region (amino acids 35-62) located between the MDM2-binding site and the proline-rich region in the amino-terminal domain of p53. Proline 163-170 P53 Homo sapiens 215-218 16518417-7 2006 These results suggested that dicoumarol could enhance cytotoxicity of CDDP in urogenital cancer cells with wild-type p53 through the p53/p21/JNK pathways. Dicumarol 29-39 P53 Homo sapiens 117-120 10226945-3 1999 One tumor sample (case 23) showed a mis-sense point mutation at codon 177, changing CCC to CTC, which resulted in a substitution of proline to leucine in the p53 protein. Proline 132-139 P53 Homo sapiens 158-161 9563901-5 1998 We also found that contrary to gamma-irradiation, Taxol and vincristine could induce apoptosis in lymphoma cell lines harboring p53 mutations. Vincristine 60-71 P53 Homo sapiens 128-131 9506540-3 1998 When p53 was expressed at sublethal levels, it sensitized cells to the DNA-damaging drugs Adriamycin, mitomycin C, actinomycin D, etoposide (VP16), cisplatin and CPT11. Dactinomycin 115-128 P53 Homo sapiens 5-8 16518417-7 2006 These results suggested that dicoumarol could enhance cytotoxicity of CDDP in urogenital cancer cells with wild-type p53 through the p53/p21/JNK pathways. Dicumarol 29-39 P53 Homo sapiens 133-136 16426567-2 2006 Using a competition assay on agarose gels we found that the p53 consensus sequences in longer DNA fragments are better targets than the same sequences in shorter DNAs. Sepharose 29-36 P53 Homo sapiens 60-63 9528853-5 1998 By 8 days after a brief exposure to DNA strand breaking agents, bleomycin or actinomycin D, p53 protein is at baseline levels, while the p53 transactivation level is only slightly above its baseline. Dactinomycin 77-90 P53 Homo sapiens 92-95 10321740-2 1999 Several functional domains necessary for mediating cell cycle arrest and apoptosis in p53 have been mapped, e.g., the proline-rich domain. Proline 118-125 P53 Homo sapiens 86-89 10321740-5 1999 We found that p53(delta62-91), which lacks all five PXXP motifs in human p53, is capable of inducing cell cycle arrest but not apoptosis, while p53(gln22-ser23/delta62-91), which contains a double point mutation in the activation domain as well as deletion of the proline-rich domain, completely loses its activity. Proline 264-271 P53 Homo sapiens 14-17 10321740-10 1999 These results suggest that the proline-rich region may play a role in chromatin remodeling, which counteracts chromatin-mediated repression for some of the endogenous p53 target genes. Proline 31-38 P53 Homo sapiens 167-170 10079089-4 1999 Ribozyme derivatives that combine a mutation which indirectly slows down the rate of the chemical cleavage step by weakening guanosine binding with additional mutations that weaken substrate binding have greatly enhanced specificity with short oligonucleotide substrates and an mRNA fragment derived from the p53 gene. Guanosine 125-134 P53 Homo sapiens 309-312 9537652-4 1998 Removal of N,N,N",N"-tetrakis(2-pyridylmethyl)ethylenediamine from culture medium allowed p53 to refold into the immunologically wild-type form, followed by a transient increase in DNA binding, expression of the cyclin-dependent kinase inhibitor p21WAF1, and cell-cycle delay in the G1 phase. N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine 11-61 P53 Homo sapiens 90-93 9891062-7 1999 Induction of p53 in response to actinomycin D or hypoxic stress decreases AFP expression. Dactinomycin 32-45 P53 Homo sapiens 13-16 16619485-1 2006 Selenium, in the form of seleno-L-methionine (SeMet), induced Redox-factor-1 (Ref1) and p53 proteins in normal human and mouse fibroblasts. Selenium 0-8 P53 Homo sapiens 88-91 10626228-2 1999 A plasmid bearing cDNA containing the human p53 gene was reacted in vitro with CAA, then dehydrated for conversion of hydroxyethano into etheno adducts, and primer extension by T7 DNA polymerase in the presence of four dNTPs was performed. hydroxyethano 118-131 P53 Homo sapiens 44-47 9464250-2 1998 We used doxorubicin (DOX) and sodium butyrate (NaB) to accumulate p53 protein. Butyric Acid 30-45 P53 Homo sapiens 66-69 16251206-2 2006 Cr(VI) exposure-related lung cancer has a high mutation incidence in the p53 gene. Chromium 0-2 P53 Homo sapiens 73-76 16531837-5 2006 Western blotting showed increased p53 protein expression in MOLT-4 cells, but not in BEAS-2B cells, after exposure to 0.5 and 3 muM hexavalent chromium for 12 hours and 4 hours, respectively. Chromium 143-151 P53 Homo sapiens 34-37 9516963-6 1998 Data demonstrated p53-dependent sensitization (> or = 4-fold) to bleomycin, actinomycin D, and 5-fluorouracil and considerably less p53-dependence (< or = 2-fold) for doxorubicin, topotecan, etoposide, and cisplatin in Cl.#27 compared to an equivalent clone containing the pGRE5-EBV vector alone (VC#3). Dactinomycin 79-92 P53 Homo sapiens 18-21 9516979-6 1998 The results suggest that MDM2-mediated resistance to p53 may be bypassed by p21 and that the Rb phosphorylation state may predict the effects on growth after Ad-p53 or Ad-p21 infection. Rubidium 93-95 P53 Homo sapiens 161-164 10757447-0 1999 Sodium butyrate modulates p53 and Bcl-2 expression in human retinoblastoma cell lines. Butyric Acid 0-15 P53 Homo sapiens 26-29 10757447-1 1999 Sodium butyrate (SB) is a potent biological modifier that can induce diverse effects including growth inhibition, differentiation, or apoptosis of many cell types including retinoblastoma (Rb), and modulation of genes such as c-fos and p53. Butyric Acid 0-15 P53 Homo sapiens 236-239 10757447-1 1999 Sodium butyrate (SB) is a potent biological modifier that can induce diverse effects including growth inhibition, differentiation, or apoptosis of many cell types including retinoblastoma (Rb), and modulation of genes such as c-fos and p53. Butyric Acid 17-19 P53 Homo sapiens 236-239 9450475-2 1997 While these cells, which express wild-type p53, were arrested in G1 after treatment with actinomycin D (a positive control), treatment with the mammary carcinogen did not cause G1 arrest but instead delayed the cells in the DNA synthesis phase. Dactinomycin 89-102 P53 Homo sapiens 43-46 9450475-3 1997 In concert with the absence of a G1 arrest, it was found that though both chemical treatments led to increased levels of p53, only the p53 induced by actinomycin D was transcriptionally active and increased the levels of the cyclin dependent kinase inhibitor, p21(waf1/cip1). Dactinomycin 150-163 P53 Homo sapiens 135-138 11835772-2 1999 METHODS: The expressions of P53 protein and proliferating cell nuclear antigen (PCNA) in 102 cases with malignant eyelid tumors were examined by labelled streptravidin biotin (LSAB) immunohistochemical technique. Biotin 168-174 P53 Homo sapiens 28-31 16186801-8 2006 Taken together, these data suggest that loss of Rb creates strong selective pressure, via DSB accumulation, for inactivating p53 mutations and that E2F1 contributes to the genetic instability associated with transformation and tumorigenesis. Rubidium 48-50 P53 Homo sapiens 125-128 14646475-8 1998 Two other agents known to induce apoptosis, vinblastine and actinomycin D, induced a similar pattern of acidic p53 species as that observed for 2-MeOE2. Dactinomycin 60-73 P53 Homo sapiens 111-114 10023442-9 1998 We also provided wild-type p53 and p53 delta 326 with tetracycline-regulated promoters and stably introduced these constructs into Saos2 and SKBR3 cells. Tetracycline 54-66 P53 Homo sapiens 35-38 9567617-9 1997 In the breast cancers the p53 is already utilized as chemoresistance marker, directing the therapy, if changed to alternative drugs (Taxolo) which have a p53-independent action. taxolo 133-139 P53 Homo sapiens 26-29 9567617-9 1997 In the breast cancers the p53 is already utilized as chemoresistance marker, directing the therapy, if changed to alternative drugs (Taxolo) which have a p53-independent action. taxolo 133-139 P53 Homo sapiens 154-157 9434849-8 1997 All nitro-PAHs tested induced C.G-->A.T transversion, which is observed as the most frequent base-substitution mutation of p53 tumor suppressor gene in human lung cancer. nitro-pahs 4-14 P53 Homo sapiens 126-129 9788606-2 1998 A common polymorphism of p53, encoding either proline or arginine at position 72, affects the susceptibility of p53 to E6-mediated degradation in vivo; Caucasian women homozygous for arginine 72 reportedly are about seven times more susceptible to HPV-associated carcinoma of the cervix than heterozygotes. Proline 46-53 P53 Homo sapiens 25-28 9788606-2 1998 A common polymorphism of p53, encoding either proline or arginine at position 72, affects the susceptibility of p53 to E6-mediated degradation in vivo; Caucasian women homozygous for arginine 72 reportedly are about seven times more susceptible to HPV-associated carcinoma of the cervix than heterozygotes. Proline 46-53 P53 Homo sapiens 112-115 16399623-5 2006 Silymarin pre-treatment reversed the effect of UV irradiation on the expression of phosphorylated Akt and phosphorylated p53 (regulated by Akt activation), followed by down-regulation of Bax and up-regulated expressions of Bcl-2 and Bcl-xL proteins in UV-irradiated A375-S2 cells. Silymarin 0-9 P53 Homo sapiens 121-124 9893672-1 1998 A new recombinant adenovirus carrying a wild-type p53 gene (AxCAp53) was developed and the combination effect of p53 gene transfer and cis-diamminedichloroplatinum (II) (CDDP) was examined in an ovarian cancer cell line, SK-OV-3, with deletion of the p53 gene. axcap53 60-67 P53 Homo sapiens 50-53 9764849-4 1998 Prior treatment of cells with cycloheximide or actinomycin D abolished the p53 increase and apoptosis induced by curcumin, suggesting that either de novo p53 protein synthesis or some proteins synthesis for stabilization of p53 is required for apoptosis. Dactinomycin 47-60 P53 Homo sapiens 75-78 9395239-7 1997 Actinomycin D or cycloheximide prevented cell death, suggesting that, in this system, p53-induced apoptosis depends upon macromolecule biosynthesis.

Butyric Acid 10-25 P53 Homo sapiens 72-75 8220069-2 1993 In our present study we observed that sodium butyrate treatment caused a decrease in the level of expression of RB1 gene on day seven of butyrate treatment but a gradual six to sevenfold decrease in the level of expression of p53 gene. Butyric Acid 38-53 P53 Homo sapiens 226-229 15352034-7 2004 In contrast, translation of c-Jun or p53 mRNA was completely inhibited by taurolidine. taurolidine 74-85 P53 Homo sapiens 37-40 8389669-2 1993 The wild-type of p53 protein exists as at least two forms of variants among human populations, ascribed to amino acid replacement at codon 72 of Arg by Pro.

Dactinomycin 0-13 P53 Homo sapiens 22-25 15310756-3 2004 We found here that knock-down of Tip60 affects the p53-dependent response following actinomycin D treatment, most likely because it inhibits p21 (CDKN1A) accumulation. Dactinomycin 84-97 P53 Homo sapiens 51-54 1486864-9 1992 The p53 gene is a tumor-suppressor gene that can encode either a proline or an arginine in the 72nd residue.

Proline 248-255 P53 Homo sapiens 69-72 12855662-3 2003 We have also evaluated the influence of major resistance mechanisms, such as expression of multidrug resistance-associated drug efflux pumps, cisplatin resistance, loss of p53 function, and absence of mismatch repair on the cytotoxic activity of irofulven. irofulven 246-255 P53 Homo sapiens 172-175 12883038-4 2003 Low adozelesin concentrations (e.g., 0.5 nM) induced a transient S-phase block and cell cycle arrest in G(2)-M, as well as increased induction of p53 and p21, whereas a high drug concentration (e.g., 2.5 nM) caused apoptosis but no p21 induction. adozelesin 4-14 P53 Homo sapiens 146-149 12771997-2 2003 Mut-p53 cells were significantly resistant to the cytotoxicity of the microtubule-targeted drugs (vinca alkaloids and taxanes), as compared with wt-p53 cells.

Proline 111-118 P53 Homo sapiens 134-137 12684687-4 2003 We report that Brca1-deficiency in p53-null cells was associated with increased sensitivity to the topoisomerase I poisons camptothecin and topotecan, the topoisomerase II poisons doxorubicin, mitoxantrone and etoposide, and to the platinum compounds carboplatin and oxaliplatin, but not to the antimetabolites 5-fluorouracil and gemcitabine and the taxanes docetaxel and paclitaxel. Mitoxantrone 193-205 P53 Homo sapiens 35-38 12711114-1 2003 The p53 gene is frequently mutated in lung tumors, and mutations may be caused by both polycyclic aromatic hydrocarbons (PAHs) and nitrosamines found in tobacco smoke. Nitrosamines 131-143 P53 Homo sapiens 4-7 12711114-12 2003 These results suggest that p53 mutations in both types of lung tumors may arise from adduction by both PAHs and nitrosamines. Nitrosamines 112-124 P53 Homo sapiens 27-30 12694871-4 2003 Binding of active, latent, and in vitro-activated p53 protein to DNA fragments modified by antitumor cisplatin was studied using electrophoretic mobility shift assay in agarose gels and immunoblotting analysis.

Protactinium 4-7 P53 Homo sapiens 42-45 12397361-3 2002 Here we report that DNA damage specifically induces p53 phosphorylation on Ser/Thr-Pro motifs, which facilitates its interaction with Pin1, a member of peptidyl-prolyl isomerase. Proline 83-86 P53 Homo sapiens 52-55 12481433-9 2002 When p53 expression was induced, cells became chemosensitive to actinomycin D in the presence or absence of MDM2 expression; this result suggests that MDM2 cannot inhibit p53-mediated chemosensitivity.

Proline 4-11 P53 Homo sapiens 39-42 12368717-12 2002 CONCLUSIONS: Association between the p53 gene encoding for proline at codon 72 and POAG presumably exists in some ethnic populations but cannot be used as a predictor for the role of the gene as a common regulator of cell death of retinal ganglions leading to POAG. Proline 59-66 P53 Homo sapiens 37-40 12065086-3 2002 The p53 codon 72 Arg/Pro polymorphism has been suggested to be associated with susceptibility to tobacco-related cancers, but this association remains controversial.

Proline 141-144 P53 Homo sapiens 56-59 12130688-4 2002 Our recent investigations with electrophilic prostaglandins enabled us to devise a pharmacophore and mechanism of action hypothesis relevant to this problem: a cross-conjugated alpha,beta-unsaturated dienone with two sterically accessible electrophilic beta-carbons is a molecular determinant that confers activity among this class of ubiquitin isopeptidases inhibitors, and that inhibitors of ubiquitin isopeptidases cause cell death in vitro independently of p53. alpha,beta-unsaturated dienone 177-207 P53 Homo sapiens 461-464 12115545-1 2002 p53 codon 72, which produces variant proteins with an arginine (Arg) or proline (Pro), has been reported to be associated with cancers of the lung, esophagus and cervix.

Carmustine 117-121 P53 Homo sapiens 50-53 11358839-6 2001 In contrast, resistance to BCNU in U87MG-neo cells was associated with up-regulation of p53, prolonged induction of p21(WAF1), sustained cell cycle arrest in S phase, and enhancement of DNA repair. Carmustine 27-31 P53 Homo sapiens 88-91 11358839-7 2001 U87MG cells with disrupted p53 function were less able to repair BCNU-induced DNA damage and survive this chemotherapeutic insult. Carmustine 65-69 P53 Homo sapiens 27-30 11497287-7 2001 After 24 hours of the N-1-sulfonylpyrimidine derivative application, the p53 oncoprotein expression could not be detected by immunocytochemical analysis. N-1-sulfonylpyrimidine 22-44 P53 Homo sapiens 73-76 11373271-4 2001 We established tetracycline-regulated, stable hRAD50 expression systems in SaOS-2 cells, which retain mutated p53, and in HeLa cells. Tetracycline 15-27 P53 Homo sapiens 110-113 11350911-2 2001 A p53-null, MGMT-proficient lung tumor cell line (H1299) was engineered to express wt p53 in a tetracycline-regulated system. Tetracycline 95-107 P53 Homo sapiens 86-89 11350911-3 2001 High levels of p53 induction achieved by tetracycline withdrawal were accompanied by G(1) cell cycle arrest without significant apoptosis in this cell line. Tetracycline 41-53 P53 Homo sapiens 15-18 11350911-9 2001 Induction of wt p53 in these models led to a 3- and 2-fold increase in sensitivity to 1,3-bis(2-chloroethyl)-1-nitrosourea and temozolomide, respectively, which generate the MGMT-repairable O(6)-alkyl adducts in DNA. Carmustine 86-122 P53 Homo sapiens 16-19 11368358-0 2001 Apoptotic response to homoharringtonine in human wt p53 leukemic cells is independent of reactive oxygen species generation and implicates Bax translocation, mitochondrial cytochrome c release and caspase activation. Homoharringtonine 22-39 P53 Homo sapiens 52-55 11258898-6 2001 Activated MAPK immunoprecipitates of nuclei from T(4)-treated cells accumulated p53 in a time-dependent manner; T(4) and T(4)-agarose were more effective than T(3). Sepharose 126-133 P53 Homo sapiens 80-83 11280728-9 2001 We hypothesize that proline oxidation supports the generation of ROS by donating reducing potential to an electron transport chain altered either by p53-dependent mechanisms or by overexpression of POX. Proline 20-27 P53 Homo sapiens 149-152 11158294-5 2001 We found that induction of p53 either by diverse stress signals or ectopically using a tetracycline-regulated promoter causes a marked reduction in CHK1 protein levels. Tetracycline 87-99 P53 Homo sapiens 27-30 11158615-5 2001 The NQO1 inhibitor dicoumarol caused a reduction in the level of both endogenous and gamma-irradiation-induced p53 in HCT116 human colon carcinoma cells. Dicumarol 19-29 P53 Homo sapiens 111-114 11158615-6 2001 This reduction was prevented by the proteasome inhibitors MG132 and lactacystin, suggesting enhanced p53 degradation in the presence of dicoumarol. Dicumarol 136-146 P53 Homo sapiens 101-104 11158615-7 2001 Dicoumarol-induced degradation of p53 also was prevented in the presence of simian virus 40 large T antigen, which is known to bind and to stabilize p53. Dicumarol 0-10 P53 Homo sapiens 34-37 11158615-7 2001 Dicoumarol-induced degradation of p53 also was prevented in the presence of simian virus 40 large T antigen, which is known to bind and to stabilize p53. Dicumarol 0-10 P53 Homo sapiens 149-152 11158615-8 2001 Cells overexpressing NQO1 were resistant to dicoumarol, and this finding indicates the direct involvement of NQO1 in p53 stabilization. Dicumarol 44-54 P53 Homo sapiens 117-120 11158615-10 2001 Dicoumarol also reduced the level of p53 in its mutant form in M1 cells. Dicumarol 0-10 P53 Homo sapiens 37-40 11013253-4 2001 Furthermore, the levels of p202 also decrease after exposure of cells to ultra violet light, which correlate with increase in the levels of p53. ultra violet 73-85 P53 Homo sapiens 140-143 11244509-6 2001 p53 phosphorylation also varied in a MTI-dependent manner, as Taxol and Vincristine induced more p53 phospho-forms than nocodazole. Vincristine 72-83 P53 Homo sapiens 0-3 11244509-6 2001 p53 phosphorylation also varied in a MTI-dependent manner, as Taxol and Vincristine induced more p53 phospho-forms than nocodazole.

Sulfur 17-23 P53 Homo sapiens 90-93 11072671-2 2000 In invasive cervical cancer, the arginine form of the p53 gene is estimated to be more susceptible to degradation mediated by tumour-associated human papilloma viruses (HPV) than the proline form. Proline 183-190 P53 Homo sapiens 54-57 10951577-8 2000 Rotenone, an inhibitor of mitochondrial complex I, and 4,4"-diisothiocyanato-stilbene-2,2"-disulfonate, a mitochondrial anion channel inhibitor, also abolished the increase in ROS signal and p53 levels during hypoxia.

Bucladesine 65-71 P53 Homo sapiens 152-155 10900468-5 2000 In addition, by using western blotting, we found that p53 protein levels increased fourfold to sixfold after exposure to sodium chromate. sodium chromate(VI) 121-136 P53 Homo sapiens 54-57 10900468-8 2000 The necessity of p53 for chromium-induced apoptosis was examined in two ways. Chromium 25-33 P53 Homo sapiens 17-20 10900468-10 2000 These studies showed that chromium-induced apoptosis was p53 dependent. Chromium 26-34 P53 Homo sapiens 57-60 10762623-0 2000 Induction of apoptosis by hexamethylene bisacetamide is p53-dependent associated with telomerase activity but not with terminal differentiation. hexamethylene bisacetamide 26-52 P53 Homo sapiens 56-59 10762623-2 2000 We found that hexamethylene bisacetamide (HMBA) induced apoptosis in human colon carcinoma LoVo cells harbouring wild-type p53 but not in SW1116 cells harbouring mutant p53. hexamethylene bisacetamide 14-40 P53 Homo sapiens 123-126 10762623-2 2000 We found that hexamethylene bisacetamide (HMBA) induced apoptosis in human colon carcinoma LoVo cells harbouring wild-type p53 but not in SW1116 cells harbouring mutant p53. hexamethylene bisacetamide 42-46 P53 Homo sapiens 123-126 10762623-4 2000 Taken together, our results suggest that HMBA can induce apoptosis via a p53-dependent pathway, but apoptosis and terminal differentiation may be separately regulated in LoVo cells. hexamethylene bisacetamide 41-45 P53 Homo sapiens 73-76 10757806-5 2000 Although normal cells and wild-type p53-expressing tumor cells showed similar responses to actinomycin D and camptothecin treatment, the transcriptional activity of stabilized p53 induced by deferoxamine mesylate, which mimics hypoxia, in normal cells was lost in all three tumor cell lines tested. Dactinomycin 91-104 P53 Homo sapiens 36-39 10802655-3 2000 The binding of such mutants is influenced by whether TP53 (encoding p53) codon 72, by virtue of a common polymorphism in the human population, encodes Arg or Pro. Proline 158-161 P53 Homo sapiens 53-57 10802655-3 2000 The binding of such mutants is influenced by whether TP53 (encoding p53) codon 72, by virtue of a common polymorphism in the human population, encodes Arg or Pro.

Biotin 64-70 P53 Homo sapiens 8-11 10801075-3 2000 The data obtained demonstrate that the growth factor activity of PAs is associated with: - a rapid transient activation of early response genes, c-fos, c-jun and c-myc; - the subsequent coordinated down-regulation of p53 and p21CIP1; - the constant expression of the MEK1 mRNA in every phase of the cell cycle. Protactinium 65-68 P53 Homo sapiens 217-220 22607421-7 2000 Compared to the intrinsic zinc strongly bound to Cys 176, Cys 238, Cys 242 and His 179 in the p53 core domain, binding of additional Zn(2+) to p53 was much weaker as shown by an easy removal of the latter ions by low concentrations of EDTA.

Dactinomycin 93-106 P53 Homo sapiens 36-39 10403534-11 1999 It can be concluded that wild-type p53 and/or up-regulation of c-myc is associated with indomethacin-mediated differential apoptosis in gastric epithelial cells.

Tetracycline 30-42 P53 Homo sapiens 156-159 10078201-0 1999 RB regulates the stability and the apoptotic function of p53 via MDM2. Rubidium 0-2 P53 Homo sapiens 57-60 10078201-1 1999 The binding of RB to MDM2 is shown to be essential for RB to overcome both the antiapoptotic function of MDM2 and the MDM2-dependent degradation of p53. Rubidium 15-17 P53 Homo sapiens 148-151 10078201-1 1999 The binding of RB to MDM2 is shown to be essential for RB to overcome both the antiapoptotic function of MDM2 and the MDM2-dependent degradation of p53.

FK 409 5-9 P53 Homo sapiens 93-96 10029405-2 1999 In this study, we showed that the p53 response to a chemotherapeutic drug, actinomycin D, was reversible in both normal and tumor cells, even when a substantial proportion of tumor cells were undergoing apoptosis. Dactinomycin 75-88 P53 Homo sapiens 34-37 10029405-3 1999 Despite the clear reversibility of the p53-induced cell-cycle arrest after removal of actinomycin D, a substantial proportion of the cells arrested in G2 failed to resume normal cell-cycle progression and underwent another round of DNA synthesis. Dactinomycin 86-99 P53 Homo sapiens 39-42 10757447-6 1999 Up to 12 h after 1 mM SB treatment, p53 and Bcl-2 expressions were similar to control levels, then gradually decreased to very low levels at 5 days.

Dactinomycin 46-59 P53 Homo sapiens 157-160 9766676-7 1998 Moreover, analysis of a tetracycline-regulated p53-inducible system in null-p53 cell lines showed that RTP/rit42 mRNA expression increased concomitantly with p53 expression and followed a similar time course.

Tetracycline 24-36 P53 Homo sapiens 76-79 30650922-3 1998 p53 expression was examined by im-munohistochemical staining using the streptavidin-biotin method. Biotin 84-90 P53 Homo sapiens 0-3 9742979-1 1998 BACKGROUND: A polymorphism at codon 72 of the human tumour-suppressor gene, p53, results in translation to either arginine or proline. Proline 126-133 P53 Homo sapiens 76-79 9707426-0 1998 The requirement for the p53 proline-rich functional domain for mediation of apoptosis is correlated with specific PIG3 gene transactivation and with transcriptional repression.

Tetracycline 87-99 P53 Homo sapiens 186-189 9575175-6 1998 Employing a stable cell line derived from p53-deficient human fibroblast that contains tetracycline-regulated transactivator and operator plasmids to control the expression of wild-type p53 (TR9-7 cells), we then show that the induction of p21(WAF1/Cip1), which occurs in response to the inhibition of PP5 expression, requires the p53 protein.

Dactinomycin 47-60 P53 Homo sapiens 252-255 9499413-6 1998 We propose that Ad12 infection, actinomycin D and araC all induce a similar or identical global damage arrest signal (perhaps a modification or altered conformation of p53) that preferentially interferes with metaphase condensation of the RNU1 and RNU2 loci.

Calcium Carbonate 19-26 P53 Homo sapiens 99-102 22638860-6 2012 We demonstrated that co-infusion of 6-OHDA with adenovirus expressing siRNA of iNOS blocked the activation of microglia, iNOS transcription, and p53-Bax-CC3 apoptotic cascade as well as significantly blocking 6-OHDA-induced decreases in DA, DOPAC, HVA, and TH levels and effectively decreased rotation number. amsonic acid 40-42 P53 Homo sapiens 145-148 22763759-6 2012 However, the growth-inhibitory activity of vincristine, doxorubicin, carboplatin, etoposide, and temozolomide was significantly impaired by silencing of TP53. Temozolomide 97-109 P53 Homo sapiens 153-157 22847428-8 2012 Our work provides in vivo evidence that expanded CAG RNAs trigger nucleolar stress and induce apoptosis via p53 and describes a polyQ pathogenic mechanism that involves the nucleolus. polyglutamine 128-133 P53 Homo sapiens 108-111 21633925-3 2012 In the present study, we show that retinoic acid enhances the cytostatic and apoptogenic properties of the novel adamantyl retinoid ST1926 in a panel of neuroblastoma cells with different p53 status and caspase 8 expression, resulting in synergistic effects as assessed by Combination Index and Isobologram analysis. adamantyl 113-122 P53 Homo sapiens 188-191 22593187-0 2012 Integrin alpha5beta1 plays a critical role in resistance to temozolomide by interfering with the p53 pathway in high-grade glioma. Temozolomide 60-72 P53 Homo sapiens 97-100 22593187-2 2012 In this study, we show that high expression of the alpha5 integrin subunit compromises temozolomide-induced tumor suppressor p53 activity in human glioblastoma cells. Temozolomide 87-99 P53 Homo sapiens 125-128 22593187-5 2012 In a functional p53 background, nutlin-3a downregulated the alpha5 integrin subunit, thereby increasing the cytotoxic effect of temozolomide. Temozolomide 128-140 P53 Homo sapiens 16-19 22593187-7 2012 Taken together, our findings indicate that negative cross-talk between alpha5beta1 integrin and p53 supports glioma resistance to temozolomide, providing preclinical proof-of-concept that alpha5beta1 integrin represents a therapeutic target for high-grade brain tumors. Temozolomide 130-142 P53 Homo sapiens 96-99 22198862-7 2012 TMA studies showed overexpression of KI67, P53, SURVIVIN and APOLLON protein and failure of expression of P27, BCL2, BAX, CHROMOGRANIN-A, SYNAPTOPHYSIN, CYCLIND1, FLIP, TRAIL, CK8, CK18, CK19 in parathyroid carcinoma was detected. 4,4-dimethylcholesta-8,14-dien-3-ol 0-3 P53 Homo sapiens 43-46 22481618-0 2012 The Rho kinase inhibitor fasudil is involved in p53-mediated apoptosis in human hepatocellular carcinoma cells. fasudil 25-32 P53 Homo sapiens 48-51 22426690-8 2012 Irbesartan also significantly altered p53, PCNA and cyclin D1 expression, which was also influenced by activated AT1R in AT1R(+)-MCF-7 cells.

Sorbitol 23-31 P53 Homo sapiens 206-209 22227536-8 2012 Our results demonstrated that BaP could induce the malignant transformation of 16HBE cells, and p53 and p-Akt (Ser473) might play crucial roles in BaP-induced carcinogenesis.

Polyphenols 10-21 P53 Homo sapiens 29-32 23285096-0 2012 Green tea polyphenols induce p53-dependent and p53-independent apoptosis in prostate cancer cells through two distinct mechanisms. Polyphenols 10-21 P53 Homo sapiens 47-50 21982800-5 2011 RCC patients with the p53Arg/Arg genotype had a signicantly low percentage of inorganic arsenic, a low percentage of monomethylarsonic acid (MMA), and a high percentage of dimethylarsinic acid (DMA), which indicates efcient arsenic methylation capacity. monomethylarsonic acid 117-139 P53 Homo sapiens 22-25 21982800-5 2011 RCC patients with the p53Arg/Arg genotype had a signicantly low percentage of inorganic arsenic, a low percentage of monomethylarsonic acid (MMA), and a high percentage of dimethylarsinic acid (DMA), which indicates efcient arsenic methylation capacity. monomethylarsonic acid 141-144 P53 Homo sapiens 22-25 21196432-5 2011 Both strategies could use tyrosinase-mediated activation of quercetin, a dietary polyphenol that induces the expression of p53 and modulates reactive oxygen species.

Docosahexaenoic Acids 124-127 P53 Homo sapiens 68-71 21811093-6 2011 Further experiments showed that the mechanism of DHA-induced autophagy associated with p53 attenuation involved an increase in the active form of AMP-activated protein kinase and a decrease in the activity of mammalian target of rapamycin. Docosahexaenoic Acids 49-52 P53 Homo sapiens 87-90 21811093-8 2011 Overall, our results demonstrate that autophagy contributes to the cytotoxicity of DHA in cancer cells harboring wild-type p53.

Temozolomide 98-101 P53 Homo sapiens 294-297 21872580-6 2011 Furthermore, the MDQ-induced G(0)/G(1) arrest was correlated with an increase in p27 and a decrease in cyclin D1 and p53. mdq 17-20 P53 Homo sapiens 117-120 21804388-7 2011 STIC and p53 signature as precursor lesions of pelvic serous cancer were seen in macroscopically inconspicuous contralateral fallopian tubes in unilateral TC, in patients with elective bilateral salpingo-oophorectomy, and in patients affected by PPC. Technetium 155-157 P53 Homo sapiens 9-12 21327711-1 2011 Our previous study demonstrated that interferon-beta markedly enhanced chemosensitivity to temozolomide; one of the major mechanisms is downregulation of O(6)-methylguanine DNA-methyltransferase transcription via p53 induction. Temozolomide 91-103 P53 Homo sapiens 213-216 21508685-5 2011 Unexpectedly, we found that two distinct BH3 mimetics, ABT737 and HA14-1, also stimulate other pro-autophagic pathways and hence activate the nutrient sensors Sirtuin 1 and AMPK, inhibit mTOR, deplete cytoplasmic p53 and trigger the IKK kinase. BH 3 41-44 P53 Homo sapiens 213-216 21340650-0 2011 Dimethylfumarate inhibits MIF-induced proliferation of keratinocytes by inhibiting MSK1 and RSK1 activation and by inducing nuclear p-c-Jun (S63) and p-p53 (S15) expression. Dimethyl Fumarate 0-16 P53 Homo sapiens 152-155 21340650-9 2011 CONCLUSION: Our results indicate that the specific inhibitory effects of DMF on RSK1 and MSK1 activation together with the induction of p-c-Jun (S63) and p-p53 (S15) lead to the inhibition of keratinocyte proliferation, partly explaining the anti-psoriatic effect of DMF.

Deferoxamine 64-67 P53 Homo sapiens 128-131 30730256-5 2019 Signaling data revealed that the activation of ERK1/2, rather than p53, is recruited for 6-MSITC-induced apoptosis. 6-(Methylsulfinyl)hexyl isothiocyanate 89-96 P53 Homo sapiens 67-70 17942461-0 2008 Identification through microarray gene expression analysis of cellular responses to benzo(a)pyrene and its diol-epoxide that are dependent or independent of p53. Benzo(a)pyrene 84-98 P53 Homo sapiens 157-160 18097607-0 2008 Diallyl disulfide induces reversible G2/M phase arrest on a p53-independent mechanism in human colon cancer HCT-116 cells. diallyl disulfide 0-17 P53 Homo sapiens 60-63 18640498-0 2008 Flavopiridol potentiates the cytotoxic effects of radiation in radioresistant tumor cells in which p53 is mutated or Bcl-2 is overexpressed. alvocidib 0-12 P53 Homo sapiens 99-102 18640498-3 2008 The purpose of the present study is to clarify whether flavopiridol enhances the cytotoxic effects of radiation in tumor cells that contain dysfunction p53 or that overexpress Bcl-2. alvocidib 55-67 P53 Homo sapiens 152-155 18640498-10 2008 CONCLUSIONS: Flavopiridol enhanced the cytotoxic effect of radiation in radioresistant tumor cells that harbor p53 dysfunction or Bcl-2 overexpression. alvocidib 13-25 P53 Homo sapiens 111-114 18640498-11 2008 A combination treatment of flavopiridol with radiation has the potential to conquer the radioresistance of malignant tumors induced by the genetic alteration of p53 or bcl-2. alvocidib 27-39 P53 Homo sapiens 161-164 18097607-6 2008 DADS also significantly induced the expression of p53, which contributes to cell cycle arrest in cancer cells, at a late time-point of 24 h. In addition, knockdown of p53 by siRNA did not affect cell cycle arrest, its reversibility, or the expression of cyclin B1 in the G2/M phase induced by DADS. diallyl disulfide 0-4 P53 Homo sapiens 50-53 30942456-1 2019 The Na+/K+-ATPase inhibitor cinobufagin exhibits numerous anticancer effects on hepatocellular carcinoma (HCC) cells expressing wild-type p53 via inhibition of aurora kinase A (AURKA) and activation of p53 signaling. cinobufagin 28-39 P53 Homo sapiens 138-141 17717041-0 2007 Synergy between docosahexaenoic acid and butyrate elicits p53-independent apoptosis via mitochondrial Ca(2+) accumulation in colonocytes. Docosahexaenoic Acids 16-36 P53 Homo sapiens 58-61 18632630-3 2008 Treatment of cells that express the mutated receptor variants with the Met inhibitor SU11274 leads, in a mutant-dependent manner, to a reduction of tyrosine phosphorylated levels of Abl and Rad51, impairs radiation-induced nuclear translocation of Rad51, and acts as a radiosensitizer together with the p53 inhibitor pifithrin-alpha by increasing cellular double-strand DNA break levels following exposure to ionizing radiation. ((3Z)-N-(3-chlorophenyl)-3-((3,5-dimethyl-4-((4-methylpiperazin-1-yl)carbonyl)-1H-pyrrol-2-yl)methylene)-N-methyl-2-oxo-2,3-dihydro-1H-indole-5-sulfonamide) 85-92 P53 Homo sapiens 303-306 17717041-11 2007 On the basis of these data, we propose that the combination of DHA and butyrate compared with butyrate alone further enhances colonocyte apoptosis by inducing a p53-independent, oxidation-sensitive, mitochondrial Ca(2+) -dependent (intrinsic) pathway. Docosahexaenoic Acids 63-66 P53 Homo sapiens 161-164 30942456-1 2019 The Na+/K+-ATPase inhibitor cinobufagin exhibits numerous anticancer effects on hepatocellular carcinoma (HCC) cells expressing wild-type p53 via inhibition of aurora kinase A (AURKA) and activation of p53 signaling. cinobufagin 28-39 P53 Homo sapiens 202-205 18428185-2 2008 Herein we report the design and characterisation of a new class of isoquinolinone inhibitors of the MDM2-p53 interaction. 1-Hydroxyisoquinoline 67-81 P53 Homo sapiens 105-108 30942456-8 2019 These results indicated that cinobufagin may induce anticancer effects on Huh-7 cells via the inhibition of AURKA and p53 signaling, and via the activation of p73 signaling, in an AURKA-dependent manner. cinobufagin 29-40 P53 Homo sapiens 118-121 30817944-5 2019 The sensitizing effect of AC to TRAIL was well correlated with inhibition of death receptor 5 (DR5) CHOP, and p53 expression. auriculasin 26-28 P53 Homo sapiens 110-113 18223691-9 2008 Inhibition of p53 transactivation by pifithrin-alpha or the kinase activity of ATM by either the specific ATM inhibitor KU-5593 or caffeine abrogated p21(WAF1/CIP1) upregulation, indicating that DAC upregulation of p21(WAF1/CIP1) was p53- and ATM-dependent in leukemia cells. ku-5593 120-127 P53 Homo sapiens 14-17 17978477-5 2007 The expression of Bid, Bax, or p53 proteins have been shown to increase correlated with the acquisition of Ara-C resistance. Cytarabine 107-112 P53 Homo sapiens 31-34 17678638-7 2007 Further studies using 1,2-dihydroxy-1,2-dihydro-6-hydroxylaminochrysene (1,2-DHD-6-NHOH-C), the putative ultimate genotoxic metabolite of 6-NC, was conducted and showed a significant induction of p53 (p<0.05) in MCF-7 cells; however, this effect was not evident in MCF-10A cells, indicating the varied DNA damage responses between the two cell lines. 1,2-dihydroxy-1,2-dihydro-6-hydroxylaminochrysene 22-71 P53 Homo sapiens 196-199 17678638-8 2007 By contrast to numerous DNA damaging agents such as BaP which is known to stimulate p53 expression, the lack of p53 response by 6-NC imply the lack of protective functions mediated by p53 (e.g. DNA repair machinery) after exposure to 6-NC and this may, in part, account for its remarkable carcinogenicity in the mammary tissue. Benzo(a)pyrene 52-55 P53 Homo sapiens 84-87 18446845-6 2008 ESS-mediated G2/M arrest was found to be associated with up-regulation of cyclin A, Cdc2, tumor suppressor p53 and cyclin dependent kinase (Cdk) inhibitor p21(WAF1/CIP1), whereas the expressions of other G2/M regulatory proteins, including cyclin B1 and Cdk2, were down-regulated compared with the control. ESS 0-3 P53 Homo sapiens 107-110 17681284-2 2007 The tumour suppressor, p53, has been reported to play a crucial role in apoptosis induced by oxidants, therefore we assessed the ability of a ONOO(-) donor, GEA 3162, to activate caspases and induce mitochondrial permeability in a p53-deficient murine bone marrow cell line, Jaws II. onoo 142-146 P53 Homo sapiens 23-26 30988561-1 2019 Ibrutinib is the only approved novel agent that is available for the treatment of relapsed-refractory and treatment-naive chronic lymphocytic leukemia patients with deletion 17p or TP53 mutation in India. ibrutinib 0-9 P53 Homo sapiens 181-185 17891139-3 2007 Here, we identify the major poly(ADP-ribosyl)ated sites of p53 by PARP-1 and find that PARP-1-mediated poly(ADP-ribosyl)ation blocks the interaction between p53 and the nuclear export receptor Crm1, resulting in nuclear accumulation of p53. poly(adp 28-36 P53 Homo sapiens 59-62 17891139-3 2007 Here, we identify the major poly(ADP-ribosyl)ated sites of p53 by PARP-1 and find that PARP-1-mediated poly(ADP-ribosyl)ation blocks the interaction between p53 and the nuclear export receptor Crm1, resulting in nuclear accumulation of p53. poly(adp 28-36 P53 Homo sapiens 157-160 17891139-3 2007 Here, we identify the major poly(ADP-ribosyl)ated sites of p53 by PARP-1 and find that PARP-1-mediated poly(ADP-ribosyl)ation blocks the interaction between p53 and the nuclear export receptor Crm1, resulting in nuclear accumulation of p53. poly(adp 28-36 P53 Homo sapiens 157-160 17632137-12 2007 CONCLUSIONS: 4-Hydroxy-2-nonenal impairs the proliferation of germ cells through the up-regulation of p53 protein, especially in testes with varicocele. 2-nonenal 22-32 P53 Homo sapiens 102-105 17632137-13 2007 Modification by 4-hydroxy-2-nonenal might alter normal function and stabilization of p53 protein. 4-hydroxy-2-nonenal 16-35 P53 Homo sapiens 85-88 17559811-9 2007 Persistent sensitivity to oxaliplatin of the p53-mutated V9P cell line was associated with oxalipatin-induced apoptosis but TAp73 was not the responsible alternative pathway. oxalipatin 91-101 P53 Homo sapiens 45-48 17469128-9 2007 Temozolomide reverses this pattern at the onset, but this effect is often brief in patients whose tumors overexpress p53 and do not harbor the 1p-19q codeletion, suggesting acquired chemoresistance. Temozolomide 0-12 P53 Homo sapiens 117-120 17472673-0 2007 Apoptosis, P53 and Bcl-2 expression in response to topical calcipotriol therapy for psoriasis. calcipotriene 59-71 P53 Homo sapiens 11-14 17472673-6 2007 RESULTS: After topical calcipotriol therapy, keratinocytes of psoriatic skin showed significant decrease of P53 (P = 0.002) and increase of Bcl-2 (P = 0.01) expression. calcipotriene 23-35 P53 Homo sapiens 108-111 17472673-9 2007 CONCLUSIONS: The results of the study suggested that one of the actions of calcipotriol in psoriasis might be exerted through induction of apoptosis, especially of keratinocytes, through a P53-independent pathway. calcipotriene 75-87 P53 Homo sapiens 189-192 17270239-6 2007 After stratification by sex, location, tumor differentiation, RUNX3 status, KRAS/BRAF status, or p53 status, CIMP-high was persistently correlated with TGFBR2 mutation. Cyclic IMP 109-113 P53 Homo sapiens 97-100 17449938-7 2007 In addition, minoxidil plus ATRA elevated phosphorylated Erk, phosphorylated Akt and the ratio of Bcl-2/Bax, but decreased the expressions of P53 and P21 more effectively than by minoxidil alone. Minoxidil 13-22 P53 Homo sapiens 142-145 17449938-8 2007 Our results suggest that minoxidil plus ATRA would additively enhance hair growth by mediating dual functions: 1) the prolongation of cell survival by activating the Erk and Akt signaling pathways, and 2) the prevention of apoptosis of DPCs and epithelial cells by increasing the ratio of Bcl-2/Bax and downregulating the expressions of P53 and P21. Minoxidil 25-34 P53 Homo sapiens 337-340 17216584-6 2007 Conversely, Noxa transcription in response to the chemotherapeutic agents cisplatin or temozolomide was inhibited by p53 knockdown. Temozolomide 87-99 P53 Homo sapiens 117-120 17216584-7 2007 Apoptosis in response to cisplatin or temozolomide was also inhibited by abrogation of p53 expression yet apoptosis in response to fenretinide or thapsigargin was unaffected. Temozolomide 38-50 P53 Homo sapiens 87-90 17298100-7 2007 We demonstrated that SERS-encoded beads could be used for multiplex detection with a model using streptavidin and p53. sers 21-25 P53 Homo sapiens 114-117 17191126-0 2007 Different levels of p53 induced either apoptosis or cell cycle arrest in a doxycycline-regulated hepatocellular carcinoma cell line in vitro. Doxycycline 75-86 P53 Homo sapiens 20-23 17147976-0 2007 Desferrioxamine (DFX) has genotoxic effects on cultured human lymphocytes and induces the p53-mediated damage response. Deferoxamine 0-15 P53 Homo sapiens 90-93 17147976-0 2007 Desferrioxamine (DFX) has genotoxic effects on cultured human lymphocytes and induces the p53-mediated damage response. Deferoxamine 17-20 P53 Homo sapiens 90-93 17147976-6 2007 Western blot analysis using antibodies to proteins involved in the p53-mediated response to DNA damage revealed that p53 was accumulated and DNA damage checkpoint kinases were activated in lymphocytes treated with DFX. Deferoxamine 214-217 P53 Homo sapiens 67-70 17147976-6 2007 Western blot analysis using antibodies to proteins involved in the p53-mediated response to DNA damage revealed that p53 was accumulated and DNA damage checkpoint kinases were activated in lymphocytes treated with DFX. Deferoxamine 214-217 P53 Homo sapiens 117-120 17147976-12 2007 Taken together, these results indicate that DFX activates p53-mediated checkpoint signals and induces apoptosis via mitochondrial damage in human peripheral blood lymphocytes. Deferoxamine 44-47 P53 Homo sapiens 58-61 17116745-8 2007 We propose that the genotoxic action of H2S propels the cell toward apoptotic death triggered initially by stabilization of p53 and subsequently involving a cascade of downstream products. Hydrogen Sulfide 40-43 P53 Homo sapiens 124-127 17145881-0 2006 A novel BH3 mimetic reveals a mitogen-activated protein kinase-dependent mechanism of melanoma cell death controlled by p53 and reactive oxygen species. BH 3 8-11 P53 Homo sapiens 120-123 17123452-6 2006 When evaluated by several pathway and biological process analysis programs, these proteins are demonstrated to be involved with a high degree of confidence (p values < 2.0 E-05) in glycolysis, propanoate metabolism, pyruvate metabolism, urea cycle and arginine/proline metabolism, as well as in the non-metabolic p53 and FAS pathways. Propionates 196-206 P53 Homo sapiens 316-319 17079445-7 2006 Nutlin-3 pretreatment also conferred protection of p53-proficient cells against cytosine arabinoside but not against doxorubicin or cisplatin. Cytarabine 80-100 P53 Homo sapiens 51-54 16926039-7 2006 Furthermore, BaP increased p53 levels in both p53 positive cell lines, as well as p21 levels in MCF-7 cells, an effect that was prevented by the p53-specific inhibitor pifithrin-alpha. Benzo(a)pyrene 13-16 P53 Homo sapiens 27-30 16926039-7 2006 Furthermore, BaP increased p53 levels in both p53 positive cell lines, as well as p21 levels in MCF-7 cells, an effect that was prevented by the p53-specific inhibitor pifithrin-alpha. Benzo(a)pyrene 13-16 P53 Homo sapiens 46-49 16926039-7 2006 Furthermore, BaP increased p53 levels in both p53 positive cell lines, as well as p21 levels in MCF-7 cells, an effect that was prevented by the p53-specific inhibitor pifithrin-alpha. Benzo(a)pyrene 13-16 P53 Homo sapiens 46-49 17050687-3 2006 In addition to its role in activating the G(1) and G(2) checkpoints, p53 also helps to protect cells in S phase when they are starved for DNA precursors by treatment with the specific aspartate transcarbamylase inhibitor N-phosphonacetyl-l-aspartate (PALA), which blocks the synthesis of pyrimidine nucleotides. Pyrimidine Nucleotides 288-310 P53 Homo sapiens 69-72 17093398-0 2006 Oxidative stress in pterygium: relationship between p53 and 8-hydroxydeoxyguanosine. 8-ohdg 60-83 P53 Homo sapiens 52-55 17093398-7 2006 To verify a possible significant association between p53 and 8-OHdG, we examined a series of 31 Ecuadorian pterygia for the expression of the two markers. 8-ohdg 61-67 P53 Homo sapiens 53-56 17093398-16 2006 All samples positive for p53 (11/31, 35.48%) were also positive for 8-OHdG immunostaining, and all specimens negative for 8-OHdG (10/31, 32.26%) were also negative for p53. 8-ohdg 68-74 P53 Homo sapiens 25-28 17093398-17 2006 When analyzed by Fisher"s exact test, 8-OHdG expression was significantly associated with p53 positivity (p=0.0049). 8-ohdg 38-44 P53 Homo sapiens 90-93 17093398-20 2006 CONCLUSIONS: Although pterygium is a lesion with limited local invasion and an inability to metastasize, the concomitant presence of altered p53 in 8-OHdG-immunoreactive cells could provide evidence of apparent genetic instability, which is in contrast to its benign clinical course. 8-ohdg 148-154 P53 Homo sapiens 141-144 16738694-0 2006 Alemtuzumab in combination with high-dose methylprednisolone is a logical, feasible and highly active therapeutic regimen in chronic lymphocytic leukaemia patients with p53 defects. Methylprednisolone 42-60 P53 Homo sapiens 169-172 16759640-4 2006 Suppression of HASMC proliferation by resveratrol was accompanied by a dose-dependent increase in the expression of tumor suppressor gene p53 and heat shock protein HSP27. hasmc 15-20 P53 Homo sapiens 138-141 16760658-8 2006 Given that glucose deprivation leads to p53 activation and 2-DG led to activation of p53 response genes in our present study (e.g., PMAIP1 and GADD45A), we examined the impact of transient p53 knockdown and observed that induction of PMAIP1 and GADD45A appear to be via p53-independent mechanisms. Deoxyglucose 59-63 P53 Homo sapiens 85-88 16760658-8 2006 Given that glucose deprivation leads to p53 activation and 2-DG led to activation of p53 response genes in our present study (e.g., PMAIP1 and GADD45A), we examined the impact of transient p53 knockdown and observed that induction of PMAIP1 and GADD45A appear to be via p53-independent mechanisms. Deoxyglucose 59-63 P53 Homo sapiens 85-88 16760658-8 2006 Given that glucose deprivation leads to p53 activation and 2-DG led to activation of p53 response genes in our present study (e.g., PMAIP1 and GADD45A), we examined the impact of transient p53 knockdown and observed that induction of PMAIP1 and GADD45A appear to be via p53-independent mechanisms. Deoxyglucose 59-63 P53 Homo sapiens 85-88 16684279-9 2006 Following calcipotriol and MPA treatments, there was a significant reduction in p53 and ki-67 positivity accompanied by an increase in bcl-2 positivity (P < 0.05 each). calcipotriene 10-22 P53 Homo sapiens 80-83 16625087-9 2006 Compared with adjacent nonatypical and nondysplastic (metaplastic) BE, areas of BCDA showed a significantly elevated prevalence rate of p53 positivity (60% vs. 13%, P<0.02) and a significantly elevated total crypt and basal crypt MIB-1 proliferation rate (P<0.001). 5-Bromo-4-chloro-3-indolyl acetate 80-84 P53 Homo sapiens 136-139 16625087-11 2006 Patients with BCDA showed a significantly increased rate of 17p(TP53) LOH (P = 0.016), aneuploidy (P = 0.004), and a trend in increased 9p(p16) LOH (P = 0.08), compared with control patients without BCDA. 5-Bromo-4-chloro-3-indolyl acetate 14-18 P53 Homo sapiens 64-68 16504179-2 2006 To determine whether this effect is due only to high level expression or the mutant nature of the protein, we have used a doxycycline-inducible lung carcinoma cell line capable of expressing wild-type p53. Doxycycline 122-133 P53 Homo sapiens 201-204 16538381-5 2006 Quinaprilat reduced Bax and p53. quinaprilat 0-11 P53 Homo sapiens 28-31 16503551-1 2006 Flavopiridol downregulates anti-apoptotic regulators including Mcl-1, upregulates p53, globally attenuates transcription through inhibition of P-TEFb, binds to DNA, and inhibits angiogenesis. alvocidib 0-12 P53 Homo sapiens 82-85 16302260-3 2006 We recently identified a synthetic thiazolidin compound, 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidione (DBPT), that induces apoptosis in human colon cancer cells, independent of p53 and P-glycoprotein status. dbpt 121-125 P53 Homo sapiens 195-198 16414131-0 2006 Monochloramine inhibits ultraviolet B-induced p53 activation and DNA repair response in human fibroblasts. chloramine 0-14 P53 Homo sapiens 46-49 16414131-5 2006 Consequently, UVB-induced increase in the downstream effectors of p53, namely p21Cip1 and Gadd45a, were almost completely inhibited by NH2Cl. chloramine 135-140 P53 Homo sapiens 66-69 16414131-9 2006 As UVB-induced DNA damage is repaired by nucleotide excision repair (NER) in human cells, these findings indicated that NH2Cl inhibited NER through the inhibition of p53 phosphorylation and accumulation, and NH2Cl probably impaired DNA damage recognition and/or ATR activation. chloramine 120-125 P53 Homo sapiens 166-169 16405512-11 2006 Conversely, p53 mimetic agents designed to stabilize the wild-type conformation of p53 sensitize glioma cells for TMZ cytotoxicity. Temozolomide 114-117 P53 Homo sapiens 12-15 16405512-11 2006 Conversely, p53 mimetic agents designed to stabilize the wild-type conformation of p53 sensitize glioma cells for TMZ cytotoxicity. Temozolomide 114-117 P53 Homo sapiens 83-86 16405512-12 2006 Collectively, these results suggest that the determination of MGMT expression and p53 status will help to identify glioma patients who will or will not respond to TMZ. Temozolomide 163-166 P53 Homo sapiens 82-85 17310826-3 2006 Comparison of the ability of the PIs indinavir, ritonavir, amprenavir, lopinavir, atazanavir, nelfinavir and saquinavir to inhibit E6-mediated proteasomal degradation of mutant p53 in E6-transfected C33A cells showed that 15 microM lopinavir, 1 mM indinavir or 125 microM ritonavir treatment for 24 h produced a stable increase in the level of nuclear p53 in these cells with minimal cell death. Saquinavir 109-119 P53 Homo sapiens 177-180 17310826-3 2006 Comparison of the ability of the PIs indinavir, ritonavir, amprenavir, lopinavir, atazanavir, nelfinavir and saquinavir to inhibit E6-mediated proteasomal degradation of mutant p53 in E6-transfected C33A cells showed that 15 microM lopinavir, 1 mM indinavir or 125 microM ritonavir treatment for 24 h produced a stable increase in the level of nuclear p53 in these cells with minimal cell death. Saquinavir 109-119 P53 Homo sapiens 352-355 16298346-6 2005 AT514 induced p53 accumulation in wild-type p53 cells but cell death was observed in both deficient and wild-type p53 cells. at514 0-5 P53 Homo sapiens 14-17 16298346-6 2005 AT514 induced p53 accumulation in wild-type p53 cells but cell death was observed in both deficient and wild-type p53 cells. at514 0-5 P53 Homo sapiens 44-47 16298346-6 2005 AT514 induced p53 accumulation in wild-type p53 cells but cell death was observed in both deficient and wild-type p53 cells. at514 0-5 P53 Homo sapiens 44-47 16298346-7 2005 Our results indicate that AT514 induces cell cycle arrest and apoptosis in breast cancer cells irrespectively of p53 status, suggesting that it might represent a potential new chemotherapeutic agent. at514 26-31 P53 Homo sapiens 113-116 16322335-5 2005 Moreover, TAp63alpha antagonizes the effect of p53 on target genes, cell viability and foci formation, and p63 gene silencing by small interfering (si) RNA results in improved p53 activity. tap63alpha 10-20 P53 Homo sapiens 47-50 16225996-6 2005 Regarding radiosensitization of tumors, a large body of evidence suggests that Ptx improves tumor oxygenation and sensitizes p53 mutant tumors. Pentoxifylline 79-82 P53 Homo sapiens 125-128 16232203-0 2005 Cisplatin-controlled p53 gene therapy for human non-small cell lung cancer xenografts in athymic nude mice via the CArG elements. carg 115-119 P53 Homo sapiens 21-24 16227412-0 2005 WMC-79, a potent agent against colon cancers, induces apoptosis through a p53-dependent pathway. WMC-79 0-6 P53 Homo sapiens 74-77 16227412-5 2005 We hypothesized that WMC-79 binding to DNA is recognized as an unrepairable damage in the tumor cells, which results in p53 activation.

Benzo(a)pyrene 27-41 P53 Homo sapiens 72-75 17564708-2 2008 In our previous experiments, we observed that IFN-beta sensitized TMZ-resistant glioma cells with the unmethylated MGMT promoter and that the mechanism of action was possibly due to attenuation of MGMT expression via induction of TP53. Temozolomide 66-69 P53 Homo sapiens 230-234 18314014-6 2008 Both DNA repair proteins, containing Fe-S clusters, and the transcription factor, p53, which is regulated through thiol-disulfide switches, can be oxidized from a distance through DNA-mediated CT. thiol-disulfide 114-129 P53 Homo sapiens 82-85 18324703-2 2008 Using analysis of proteins related to cell cycle and apoptotic pathways, we confirmed an elevated level of p53 accompanying p21 Waf1/Cip1 protein in genistein-treated or genistin-treated A549 and WI-38 cells, but not in HeLa cells. genistin 170-178 P53 Homo sapiens 107-110 18510179-13 2008 The p53 Ab-negative patients may predict a high clinical OR rate in anthracycline-based NAC. nac 88-91 P53 Homo sapiens 4-7 18284706-5 2008 Wild type full-length p53 protein was produced in fusion with biotin carboxyl carrier peptide (BCCP) or hexahistidine [(His)6] using pAK400 and pET15b(+) vectors, respectively. His-His-His-His-His-His 104-117 P53 Homo sapiens 22-25 18006205-5 2008 Gene expression of p21 was also induced by DON treatment in a dose-dependent manner with no increase in p53 protein levels, suggesting p53-independent p21 induction. deoxynivalenol 43-46 P53 Homo sapiens 135-138 17942461-7 2008 Interestingly, DNA adduct formation after BaP, but not BPDE, exposure was p53 dependent with 10-fold lower levels detected in p53-null cells.

Benzo(a)pyrene 42-45 P53 Homo sapiens 126-129 17942461-8 2008 Other cell lines were investigated for BaP-DNA adduct formation and in these the effect of p53 knockdown was also to reduce adduct formation. Benzo(a)pyrene 39-42 P53 Homo sapiens 91-94 17942461-9 2008 Taken together, these results give further insight into the role of p53 in the response of human cells to BaP and BPDE and suggest that loss of this tumour suppressor can influence the metabolic activation of BaP. Benzo(a)pyrene 106-109 P53 Homo sapiens 68-71 17942461-9 2008 Taken together, these results give further insight into the role of p53 in the response of human cells to BaP and BPDE and suggest that loss of this tumour suppressor can influence the metabolic activation of BaP.

Doxycycline 36-46 P53 Homo sapiens 124-127 18784437-4 2008 In this study, we assessed whether LMB augments the transduced p53 gene effect. leptomycin B 35-38 P53 Homo sapiens 63-66 18784437-8 2008 RESULTS: LMB induced cell death in a dose-dependent manner and p53 drastically accumulated in the nucleus after LMB treatment. leptomycin B 112-115 P53 Homo sapiens 63-66 17804695-7 2007 Molecular studies indicate the prevalent activities of DMAPT include induction of oxidative stress responses, inhibition of NF-kappaB, and activation of p53. LC-1 compound 55-60 P53 Homo sapiens 153-156 17958425-7 2007 Finally, we show that treatment of adhered LNCaP or T-47D cells with (+)-avrainvillamide leads to an increase in cellular p53 concentrations, and that siRNA-promoted depletion of nucleophosmin in a population of HeLa S3 cells leads to increased sensitivity of that population toward apoptotic death upon treatment with (+)-avrainvillamide. avrainvillamide 69-88 P53 Homo sapiens 122-125 17968428-3 2007 In the present study, we show that sensitivity of melanoma cells to TMZ was dependent on their p53 status and levels of MGMT. Temozolomide 68-71 P53 Homo sapiens 95-98 17968428-9 2007 These results are consistent with the view that TMZ is relatively ineffective against melanoma due to defective apoptotic signalling resulting from activation of p53. Temozolomide 48-51 P53 Homo sapiens 162-165 17631051-5 2007 CD8(+) T cell precursors responsive to wt p53 epitopes were detected in the circulation of most subjects with early disease, and an elevated blood Tc(1)/Tc(2) ratio distinguished wt p53 peptide responders from non-responders. tc(2) 153-158 P53 Homo sapiens 182-185 17938270-7 2007 Moreover, epothilone B and D increased the expressions of NF-kappaB-dependent apoptotic cell death regulatory genes, i.e., Bax, p53, and the active form of caspase-3, but reduced Bcl-2 expression, and these actions were partially reversed by salicylic acid. epothilone B 10-22 P53 Homo sapiens 128-131 17636258-8 2007 We hypothesize that targeted necrosis by p53p-Ant is dependent on mutant p53, is mediated by O(2)(.) o(2) 93-97 P53 Homo sapiens 41-45 17636258-8 2007 We hypothesize that targeted necrosis by p53p-Ant is dependent on mutant p53, is mediated by O(2)(.) o(2) 93-97 P53 Homo sapiens 41-44 17517898-2 2007 To develop a Chk1-specific cell-based assay, stable clones were established in which Chk1 kinase domain fused at its N-terminus with p53 through 4 tandem repeats of Gly-Gly-Gly-Gly-Ser was expressed in an inducible manner. glycyl-glycyl-glycyl-glycine 165-180 P53 Homo sapiens 133-136 17638905-5 2007 beta-Lapachone (beta-lap; also known as ARQ 501), currently in phase II clinical trials for the treatment of pancreatic cancer, causes a novel caspase- and p53-independent cell death in cancer cells overexpressing NAD(P)H:quinone oxidoreductase-1 (NQO1). beta-lapachone 0-14 P53 Homo sapiens 156-159 17638905-5 2007 beta-Lapachone (beta-lap; also known as ARQ 501), currently in phase II clinical trials for the treatment of pancreatic cancer, causes a novel caspase- and p53-independent cell death in cancer cells overexpressing NAD(P)H:quinone oxidoreductase-1 (NQO1). beta-lapachone 16-24 P53 Homo sapiens 156-159 17609380-8 2007 Kinetically, beta-lapachone-induced cell death was characterized by the following: (i) dramatic reactive oxygen species (ROS) formation, eliciting extensive DNA damage; (ii) hyperactivation of poly(ADP-ribose)polymerase-1 (PARP-1); (iii) depletion of NAD+/ATP levels; and (iv) proteolytic cleavage of p53/PARP-1, indicating mu-calpain activation and apoptosis. beta-lapachone 13-27 P53 Homo sapiens 301-304 17610718-7 2007 Oxidative stress response genes diminish the activity of cantharidin by inducing DNA strand breaks which may be subject to base excision repair and induce apoptosis in a p53- and Bcl2-dependent manner. Cantharidin 57-68 P53 Homo sapiens 170-173 17695552-6 2007 Celecoxib had no effects on expression of MAPKs, Bax, or p21; however, it increased expression of p53 and 14-3-4sigma, and reduced expression of Bcl-2. Celecoxib 0-9 P53 Homo sapiens 98-101 17695552-9 2007 CONCLUSION: The results suggest that celecoxib induced cytotoxicity and apoptosis in this line of glioma cells and that such effects might be related to activation of p53 and 14-3-3sigma, reduced Bcl-2 and Bcl-2/Bax ratio, and increased caspace-3 activity. Celecoxib 37-46 P53 Homo sapiens 167-186 17599036-5 2007 GLA decreased the anti-oxidant content of tumor cells, expression of oncogenes ras, and Bcl-2, enhanced the activity of p53, protected normal cells and tissues from the toxic actions of radiation and anti-cancer drugs, enhanced the cytotoxic action of anti-cancer drugs and reversed tumor cell drug resistance. gamma-Linolenic Acid 0-3 P53 Homo sapiens 120-123 17408702-1 2007 We analyzed the effect of exposure to carcinogenic polycyclic aromatic hydrocarbons (c-PAHs) in ambient air on the plasma levels of p53 and p21(WAF1) proteins among city policemen, bus drivers and controls in three European cities: Prague (Czech Republic), Kosice (Slovakia) and Sofia (Bulgaria). c-pahs 85-91 P53 Homo sapiens 132-135 17408702-11 2007 Among all subjects p53 plasma levels were positively correlated with p21(WAF1) levels, exposure to B[a]P, c-PAHs and levels of total DNA adducts; for p21(WAF1) levels we observed the positive correlation with cotinine, c-PAHs exposure, total and B[a]P-like DNA adduct levels. c-pahs 106-112 P53 Homo sapiens 19-22 17408702-11 2007 Among all subjects p53 plasma levels were positively correlated with p21(WAF1) levels, exposure to B[a]P, c-PAHs and levels of total DNA adducts; for p21(WAF1) levels we observed the positive correlation with cotinine, c-PAHs exposure, total and B[a]P-like DNA adduct levels. c-pahs 219-225 P53 Homo sapiens 19-22 17408702-12 2007 In conclusion our results suggest that p53 and p21(WAF1) proteins plasma levels may be useful biomarkers of c-PAHs environmental exposure. c-pahs 108-114 P53 Homo sapiens 39-42 17563398-6 2007 Additionally, DFO treatment also led to the activation of Chk1, p53, and Akt, where DFO-induced activation of p53, Chk1, and Akt occurred in both PKCdelta-dependent and -independent manners. Deferoxamine 14-17 P53 Homo sapiens 64-67 17563398-6 2007 Additionally, DFO treatment also led to the activation of Chk1, p53, and Akt, where DFO-induced activation of p53, Chk1, and Akt occurred in both PKCdelta-dependent and -independent manners. Deferoxamine 14-17 P53 Homo sapiens 110-113 17563398-6 2007 Additionally, DFO treatment also led to the activation of Chk1, p53, and Akt, where DFO-induced activation of p53, Chk1, and Akt occurred in both PKCdelta-dependent and -independent manners. Deferoxamine 84-87 P53 Homo sapiens 64-67 17563398-6 2007 Additionally, DFO treatment also led to the activation of Chk1, p53, and Akt, where DFO-induced activation of p53, Chk1, and Akt occurred in both PKCdelta-dependent and -independent manners.

Lithium 0-7 P53 Homo sapiens 68-71 15473930-6 2004 In addition,the expression of Ki76 had a positive correlation with the expressions of p53, and C-erbB-2 (P< 0.05), but not with the expression of VEGF (P >0.05). ki76 30-34 P53 Homo sapiens 86-89 15475437-9 2004 Budesonide treatment resulted in a modest decrease in p53 and BclII protein expression in bronchial biopsies and a slightly higher rate of resolution of computed tomography-detected lung nodules. Budesonide 0-10 P53 Homo sapiens 54-57 15561702-10 2005 These results suggest that up-regulation of p53-dependent Noxa expression may play an important role in the pathogenesis of atherosclerosis induced by HCy and that an increase in vascular NO production may prevent HCy-induced endothelial dysfunction by S-nitrosylation. Homocysteine 151-154 P53 Homo sapiens 44-47 15546879-4 2005 Our results showed that simultaneous 5-FU and DENSPM, a spermine analogue, synergistically increased transcript levels of the polyamine catabolism enzyme spermidine/spermine N1-acetyltransferase, depleted spermine and spermidine, increased acetylated spermidine, and produced synergistic tumor cell apoptosis in both p53 wild-type and p53-null variants.

BH 3 117-120 P53 Homo sapiens 32-35 30400061-2 2019 This tumor suppression system is based upon the kill switch being triggered in cells in which p53 has been inactivated; such kill switch consisting of a rapid, catastrophic increase in ROS caused by the induction of irreversible uncompetitive inhibition of glucose-6- phosphate dehydrogenase (G6PD), which requires high concentrations of both inhibitor (DHEA) and G6P substrate.

Doxycycline 42-53 P53 Homo sapiens 62-65 14513366-1 2003 PURPOSE: Resistance to chemotherapeutic drugs is a hallmark of many human cancers, which can occur independent of p53 gene status; however, the presence of wild-type p53 in chemorefractory tumors confers greater resistance to cisplatin, but such tumors do not display complete cross-resistance to the platinum analog (1R,2R-diaminocyclohexane)(trans-diacetato)(dichloro)platinumIV (DACH-Ac-Pt). (diaminocyclohexane)(diacetato)(dichloro)platinum 382-392 P53 Homo sapiens 166-169 14513366-4 2003 RESULTS: In response to CDDP and DACH-Ac-Pt, both CDDP-sensitive and CDDP-resistant models demonstrated time- and dose-dependent inductions of total p53 protein and an increase in Ser-15 phosphorylation, which was more pronounced with CDDP. (diaminocyclohexane)(diacetato)(dichloro)platinum 33-43 P53 Homo sapiens 149-152 14617104-0 2003 Effects of a melanogenic bicyclic monoterpene diol on cell cycle, p53, TNF-alpha, and PGE2 are distinct from those of UVB. bicyclic 25-33 P53 Homo sapiens 66-69 12787880-0 2003 Enforced expression of the tumor suppressor p53 renders human leukemia cells (U937) more sensitive to 1-[beta-D-arabinofuranosyl]cytosine (ara-C)-induced apoptosis. Cytarabine 102-137 P53 Homo sapiens 44-47 12787880-0 2003 Enforced expression of the tumor suppressor p53 renders human leukemia cells (U937) more sensitive to 1-[beta-D-arabinofuranosyl]cytosine (ara-C)-induced apoptosis. Cytarabine 139-144 P53 Homo sapiens 44-47 12787880-7 2003 Significantly, ptsp53 cells synchronized in S phase were markedly more sensitive to ara-C-mediated mitochondrial injury and apoptosis at 32 degrees, indicating that wild-type p53 specifically enhances the susceptibility of this subpopulation to ara-C lethality. Cytarabine 84-89 P53 Homo sapiens 18-21 12787880-8 2003 Consistent with these results, transient transfection of human wild-type p53 cDNA rendered parental U937 cells more sensitive to ara-C-mediated cell death. Cytarabine 129-134 P53 Homo sapiens 73-76 12787880-9 2003 Collectively, these findings indicate that p53 expression renders S-phase U937 cells more susceptible to ara-C-mediated mitochondrial dysfunction, cytochrome c release, apoptosis, and loss of clonogenic survival without enhancing ara-C metabolism. Cytarabine 105-110 P53 Homo sapiens 43-46 12781215-7 2003 Ara-C increased the level of p53 in both CV1-P and SH-SY5Y cells compared to control. Cytarabine 0-5 P53 Homo sapiens 29-32 12781215-10 2003 Our results prove that Ara-C- induced apoptosis in CV1-P cells is associated with an increase of p53 and activation of caspase-3.

Letrozole 15-18 P53 Homo sapiens 121-124 29883905-13 2018 Also, the decrease in p53 gene expression, even at low exposure levels, reinforces the carcinogenicity effect of benzene in this pathway. Benzene 113-120 P53 Homo sapiens 22-25 14644313-10 2003 Thus, for benzo(a)pyrene (at 10-50 adducts per 10(8) nucleotides) repair was essentially complete within 1 day in p53(+/+) human fibroblasts while no repair was detected within 3 days in p53(-/-) cells.

Doxycycline 171-182 P53 Homo sapiens 101-104 14500353-14 2003 Inhibition of COX-2 by celecoxib appears to alleviate this effect on p53 by reducing electrophilic PG synthesis. Celecoxib 23-32 P53 Homo sapiens 69-72 29883905-14 2018 Therefore, our results suggest that the promotion of immune evasion together with a decrease in p53 gene expression may play an important role in the benzene toxicity mechanism. Benzene 150-157 P53 Homo sapiens 96-99 30197678-8 2018 In conclusion, TGCG induced cell cycle arrest at the G0/G1 and G2/M phases and induced apoptosis in HT-29 cells through the c-Myc- and p53-mediated signaling pathways, possibly in response to DNA damage. tgcg 15-19 P53 Homo sapiens 135-138 12820894-2 2003 It has been reported that 4-HNE treatment in human cells induces a high frequency of G.C to T.A mutations at the third base of codon 249 (AGG*) of the p53 gene, a mutational hot spot in human cancers, particularly in hepatocellular carcinoma. 4-hydroxy-2-nonenal 26-31 P53 Homo sapiens 151-154 12679912-1 2003 AIM: One of the characteristics of hepatocellular carcinoma (HCC) in Qidong area is the selective mutation resulting in a serine substitution at codon 249 of the p53 gene (1, 20), and it has been identified as a "hotspot" mutation in heptocellular carcinomas occurring in populations exposed to aflatoxin and with high prevalence of hepatitis B virus carriers (2,3,9, 10,16,24).

Cytarabine 97-102 P53 Homo sapiens 24-27 29908302-7 2018 These findings indicate that PXR is a factor interfering the formation of ammonia-induced hepatocyte autophagy, and its inhibitory effect is achieved when P53 downregulates the expression and activity of AMPKbeta1. Ammonia 74-81 P53 Homo sapiens 155-158 12641444-7 2003 Of this group, arsenic trioxide was the strongest inducer of cellular p53, while dimethylarsinic acid, iododimethylarsine, and sodium arsenite also caused p53 induction in a dose- and time-dependent manner. Iododimethylarsine 103-121 P53 Homo sapiens 155-158 30246777-6 2018 We also found that the protein and mRNA levels of Bax, p53, and Fas dose-dependently increased in DFO-treated K562 cells, while the level of Bcl-2 markedly decreased in a dose-dependent manner. Deferoxamine 98-101 P53 Homo sapiens 55-58 12650433-5 2003 In MGMT-depleted cells, TMZ exposure led to DNA single-strand breaks and phosphorylation of cdc2, followed by G2-M arrest, induction of p53/p21, and DNA double-strand breaks. Temozolomide 24-27 P53 Homo sapiens 136-139 12390361-8 2002 p53 protein was more often positive in stromal cells of HCP (67%) than in LCP (50%). hcp 56-59 P53 Homo sapiens 0-3 29752478-6 2018 Furthermore, bafilomycin C1 decreased the expression of Bcl-2; increased the expression of Bax, p53, and P-p53; and increased cleavage of caspase-9 and caspase-3, thereby inducing the intrinsic caspase-dependent apoptotic pathway. bafilomycin C1 13-27 P53 Homo sapiens 96-99 12395332-7 2002 A similar relative risk was found using 249ser-p53 mutation as a marker for aflatoxin exposure.

Thymine 57-64 P53 Homo sapiens 120-123 11945174-9 2002 Finally, DFO-induced senescence-like arrest was found to be independent of p53, since cell-cycle arrest was still observed with two p53-negative cell lines, Huh7 and Hep3B cells. dfo 9-12 P53 Homo sapiens 132-135 29749471-9 2018 Furthermore, blockade of temozolomide (TMZ)-induced autophagy by 3-methyladenine (3-MA) resulted in enhanced activation of apoptotic markers, as well as tumor suppresor protein p53 (p53) expression in U87MG cells.

Temozolomide 25-37 P53 Homo sapiens 182-185 12160929-8 2002 The levels of p53 and Bax proteins were elevated, while Bcl-2 protein was downregulated in TCE- or PERC-treated p53-WT H460 cells. Trichloroethylene 91-94 P53 Homo sapiens 112-115 29749471-9 2018 Furthermore, blockade of temozolomide (TMZ)-induced autophagy by 3-methyladenine (3-MA) resulted in enhanced activation of apoptotic markers, as well as tumor suppresor protein p53 (p53) expression in U87MG cells. Temozolomide 39-42 P53 Homo sapiens 177-180 12160929-10 2002 These data suggest that, in human lung cancer cells, GSH plays a vital role in the protection of TCE- and PERC-induced oxidative stress and apoptosis, which may be mediated through a p53-dependent pathway.

Cytarabine 40-50 P53 Homo sapiens 105-109 11522624-13 2001 These data are consistent with the hypothesis that chemical carcinogens such as BP in cigarette smoke cause G:C to T:A transversions at p53 codons 157, 248, and 249 and that nontumorous lung tissues from smokers with lung cancer carry a high p53 mutational load at these codons. Benzo(a)pyrene 80-82 P53 Homo sapiens 136-139 11522624-13 2001 These data are consistent with the hypothesis that chemical carcinogens such as BP in cigarette smoke cause G:C to T:A transversions at p53 codons 157, 248, and 249 and that nontumorous lung tissues from smokers with lung cancer carry a high p53 mutational load at these codons.

Temozolomide 191-194 P53 Homo sapiens 57-60 28819011-6 2017 In conclusion, we show that TP53 mutations identify a phenotypically distinct and highly aggressive form of MCL with poor or no response to regimens including cytarabine, rituximab, and autologous stem-cell transplant (ASCT). Cytarabine 159-169 P53 Homo sapiens 28-32 11423906-3 2001 In the present study we demonstrated that infection with p53 expressing adenovirus (Ad-p53), enhances chemosensitivity of MR-deficient tumor cell lines to the methylating agent temozolomide (TZM), either used as single agent or, more efficiently, when combined with PARP inhibitor.

Doxycycline 185-196 P53 Homo sapiens 26-29 12600942-6 2003 Specifically, loss of one p53 allele dramatically facilitates the progression of mammary tumors to a Wnt1-independent state both by impairing the regression of primary tumors following doxycycline withdrawal and by promoting the recurrence of fully regressed tumors in the absence of doxycycline. Doxycycline 284-295 P53 Homo sapiens 26-29 11182788-4 2001 Likewise, accumulation of these proteins was observed in the wild-type TP53 cells after exposure to conditioned medium from irradiated mutant TP53 cells, and the accumulation was abolished by the addition of a specific nitric oxide scavenger, 2-(4-carboxyphenyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide, to the medium. 1,3-dihydroxy-4,4,5,5-tetramethyl-2-(4-carboxyphenyl)tetrahydroimidazole 243-309 P53 Homo sapiens 142-146 28910957-10 2017 Among them, the effect of NAC in patients with two or more genes copy number variations of c-Myc, CCND1, p53, p16 were poorer than that in patients with one or not gene copy number variations (P=0.000). nac 26-29 P53 Homo sapiens 105-108 11273007-5 2001 IPTG induction of AD7c-NTP gene expression resulted in increased cell death mediated by apoptosis, impaired mitochondrial function, and increased cellular levels of the p53 and CD95 pro-apoptosis gene products as occur in AD. Isopropyl Thiogalactoside 0-4 P53 Homo sapiens 169-172 12507920-8 2002 These results are also consistent with the hypothesis that BP (PAH) induce G:C to T:A transversion mutations in the hotspot codons of the p53 tumor suppressor gene and are thus involved in malignant transformation of the lung tissue of smokers.

Temozolomide 74-77 P53 Homo sapiens 86-90 11090076-8 2000 These findings indicate that treatment with etoposide, Ara-C, or doxorubicin up-regulates DR5 levels in a p53-independent manner and sensitizes human acute leukemia cells to Apo-2L-induced apoptosis. Cytarabine 55-60 P53 Homo sapiens 106-109 28821714-10 2017 Thus, in this study, we investigated the genes influenced by TMZ that were important in GBM therapy, and revealed that GADD45A plays a protective role against TMZ treatment which may through TP53-dependent and MGMT-dependent pathway in TMZ-sensitive and TMZ-resistant GBM, respectively. Temozolomide 61-64 P53 Homo sapiens 191-195 12373335-13 2002 Whereas the p53-positive endothelial cells underwent programmed cell death as demonstrated by M30, ISEL and Hoechst 33342, some fibroblasts seemed to accumulate the p53 antibody, but this did not induce apoptotic cascades. bisbenzimide ethoxide trihydrochloride 108-121 P53 Homo sapiens 12-15 28797070-4 2017 We find that methyl pyruvate protects irinotecan-treated normal lung fibroblast cell line (MRC-5) probably by turning off the p53/p21 axis of the apoptotic pathways. methyl pyruvate 13-28 P53 Homo sapiens 126-129 12205035-5 2002 p53 activation was largely attenuated if SMCs were pretreated with SB202190, a specific p38MAPK inhibitor, or were stably transfected with dominant negative rac, an upstream signal transducer of p38MAPK pathways. 4-(4-fluorophenyl)-2-(4-hydroxyphenyl)-5-(4-pyridyl)imidazole 67-75 P53 Homo sapiens 0-3 11964141-7 2002 Bathocuproinedisulphonic acid as well as the hydroxyl radical scavenger d-mannitol inhibited the PDTC-dependent increase in p53 protein and oxidation.

Aflatoxins 79-88 P53 Homo sapiens 0-4 10900010-4 2000 Here we show that treatment with the small molecule nuclear export inhibitor, leptomycin B, and actinomycin D leads to the accumulation of transcriptionally active p53 in the nucleus of HeLa, CaSki, and SiHa cells. leptomycin B 78-90 P53 Homo sapiens 164-167 10340385-9 1999 In concordance with these observations we have found that expression of ras oncogene caused in p53-defective cells further mitigation of ethyl-metansulphonate-induced G1 and G2 cell cycle arrest, but did not abrogate G1 and G2 cell cycle checkpoints in cells with normal p53 function. ethyl-metansulphonate 137-158 P53 Homo sapiens 95-98 10340385-9 1999 In concordance with these observations we have found that expression of ras oncogene caused in p53-defective cells further mitigation of ethyl-metansulphonate-induced G1 and G2 cell cycle arrest, but did not abrogate G1 and G2 cell cycle checkpoints in cells with normal p53 function. ethyl-metansulphonate 137-158 P53 Homo sapiens 271-274 28386336-8 2017 A combination of celecoxib and irradiation treatment induced much more gamma-H2AX foci formation, higher levels of radiation injury-related proteins phosphorylation, G2/M arrest, apoptosis, and p53 and p21 expression, and lower levels of Cyclin B1 in HCT116 cells than those in cells treated with irradiation alone. Celecoxib 17-26 P53 Homo sapiens 194-197 10360653-7 1999 p21 expression is induced by boswellic acids via a p53-independent pathway. boswellic acid 29-44 P53 Homo sapiens 51-54 10360653-8 1999 Ectopic expression of wild-type p53 also induces p21, and facilitates boswellic acid-induced apoptosis. boswellic acid 70-84 P53 Homo sapiens 32-35 11229523-6 2000 Genes that encode proteins important for cellular defenses against oxidative stress, such as the cysteine-rich metallothioneins (MTs), are also activated by hemopexin, as are proteins that regulate cell cycle control including p21WAF1 and the tumor suppressor p53. cysteine-rich metallothioneins 97-127 P53 Homo sapiens 260-263 28386336-11 2017 Celecoxib affects the functions of p53 and inhibits the recovery from the irradiation-induced injury by up-regulating the expression of BCCIP, and subsequently regulates the expressions of genes such as p21 and Cyclin B1 to enhance the radiosensitivity of HCT116 cells in a COX-2 independent manner. Celecoxib 0-9 P53 Homo sapiens 35-38 10212189-5 1999 UVC-induced phosphorylation of p53 at serine 389 was markedly impaired by either pretreatment of cells with p38 kinase inhibitor, SB202190, or stable expression of a dominant negative mutant of p38 kinase. 4-(4-fluorophenyl)-2-(4-hydroxyphenyl)-5-(4-pyridyl)imidazole 130-138 P53 Homo sapiens 31-34 28130034-0 2017 NICE guidance on ibrutinib for previously treated chronic lymphocytic leukaemia and untreated chronic lymphocytic leukaemia in the presence of 17p deletion or TP53 mutation. ibrutinib 17-26 P53 Homo sapiens 159-163 10212189-9 1999 Furthermore, pretreatment of cells with SB202190 blocked the p53 DNA binding activity and p53-dependent transcription. 4-(4-fluorophenyl)-2-(4-hydroxyphenyl)-5-(4-pyridyl)imidazole 40-48 P53 Homo sapiens 61-64 10212189-9 1999 Furthermore, pretreatment of cells with SB202190 blocked the p53 DNA binding activity and p53-dependent transcription. 4-(4-fluorophenyl)-2-(4-hydroxyphenyl)-5-(4-pyridyl)imidazole 40-48 P53 Homo sapiens 90-93 10837373-3 2000 In the present study, the induction of p53 target gene expression after the treatment with either benzo(a)pyrene (B[a]P) or 1-nitropyrene (1-NP) was investigated. Benzo(a)pyrene 98-112 P53 Homo sapiens 39-42 28031409-3 2017 The current study demonstrates that, unlike cisplatin, platinum analogues oxaliplatin and DACH-diacetato-dichloro-Pt(IV) (DAP) strongly stabilize and activate p53v172F in resistant cells, as indicated by prolonged p53 half-life and transactivation of targets p21 (CDKN1A) and MDM2. dap 122-125 P53 Homo sapiens 159-162 10811119-3 2000 Consistent with this possibility, treatment of A549 human lung cancer cells with clinically achievable concentrations of flavopiridol resulted in rapid elevations of the DNA damage-responsive protein p53. alvocidib 121-133 P53 Homo sapiens 200-203 10811129-0 2000 Microsatellite instability at selected tetranucleotide repeats is associated with p53 mutations in non-small cell lung cancer. tetranucleotide 39-54 P53 Homo sapiens 82-85 10811129-11 2000 Primary lung cancers with microsatellite alterations at selected tetranucleotide repeats have a high frequency of p53 mutations and do not display a phenotype consistent with defects in mismatch repair. tetranucleotide 65-80 P53 Homo sapiens 114-117 10216216-7 1999 Mutations in p53 exons 6 and 7 have been reported in the childhood papillary thyroid carcinomas in Belarus presumably as a result of radioiodine fall-out. Iodine-131 133-144 P53 Homo sapiens 13-16 10075936-5 1999 This report also demonstrates that the cytoplasmic localization of p53 in neuroblastoma cells is due to its hyperactive nuclear export: p53 in these cells can be trapped in the nucleus by the export-inhibiting drug leptomycin B or by binding a p53-tetramerization domain peptide that masks the NES. leptomycin B 215-227 P53 Homo sapiens 67-70 10075936-5 1999 This report also demonstrates that the cytoplasmic localization of p53 in neuroblastoma cells is due to its hyperactive nuclear export: p53 in these cells can be trapped in the nucleus by the export-inhibiting drug leptomycin B or by binding a p53-tetramerization domain peptide that masks the NES. leptomycin B 215-227 P53 Homo sapiens 136-139 10075936-5 1999 This report also demonstrates that the cytoplasmic localization of p53 in neuroblastoma cells is due to its hyperactive nuclear export: p53 in these cells can be trapped in the nucleus by the export-inhibiting drug leptomycin B or by binding a p53-tetramerization domain peptide that masks the NES. leptomycin B 215-227 P53 Homo sapiens 136-139 10937051-8 2000 Boric acid was used for antigen retrieval on sections stored for 12 weeks at 20 degrees C. For both p53 protein and MIB1 antigen, this resulted in an extent and intensity of immunostaining equal to or higher than (MIB1) that obtained in freshly cut sections, using citrate buffer. boric acid 0-10 P53 Homo sapiens 100-103 28031409-3 2017 The current study demonstrates that, unlike cisplatin, platinum analogues oxaliplatin and DACH-diacetato-dichloro-Pt(IV) (DAP) strongly stabilize and activate p53v172F in resistant cells, as indicated by prolonged p53 half-life and transactivation of targets p21 (CDKN1A) and MDM2. dap 122-125 P53 Homo sapiens 214-217 28231799-5 2017 METHODS: We aimed to compare the cytotoxic effects of cisplatin and a trans-sulfonamide-platinum-complex (TSPC), in two human melanoma cell lines that differ in their TP53 status: SK-MEL-5, TP53 wild type, and SK-MEL-28, TP53 mutated. trans-sulfonamide-platinum 70-96 P53 Homo sapiens 167-171 10671668-4 2000 In tumors treated with nedaplatin, they also increased, but the incidences of p53 protein-positive cells and apoptosis induced by 32 mg/kg nedaplatin, 1/2 LD50, were lower than those induced by 1 Gy irradiation. nedaplatin 23-33 P53 Homo sapiens 78-81 10064859-13 1999 More strikingly, the relationship between aflatoxin exposure and development of human hepatocellular carcinoma (HHC) was demonstrated by the studies on the p53 tumor suppressor gene. Aflatoxins 42-51 P53 Homo sapiens 156-159 10064859-14 1999 High frequency of p53 mutations (G-->T transversion at codon 249) was found to occur in HHC collected from populations exposed to high levels of dietary aflatoxin in China and Southern Africa. Aflatoxins 156-165 P53 Homo sapiens 18-21 10751606-2 2000 To further characterize p53-mediated DNA repair, we studied the effect of p53 status on the ability of the DNA repair inhibitor 1-ss-D-arabinofuranosylcytosine (AraC) to sensitize MEF to bleomycin-induced chromatid aberrations. Cytarabine 161-165 P53 Homo sapiens 24-27 10751606-2 2000 To further characterize p53-mediated DNA repair, we studied the effect of p53 status on the ability of the DNA repair inhibitor 1-ss-D-arabinofuranosylcytosine (AraC) to sensitize MEF to bleomycin-induced chromatid aberrations. Cytarabine 161-165 P53 Homo sapiens 74-77 28231799-5 2017 METHODS: We aimed to compare the cytotoxic effects of cisplatin and a trans-sulfonamide-platinum-complex (TSPC), in two human melanoma cell lines that differ in their TP53 status: SK-MEL-5, TP53 wild type, and SK-MEL-28, TP53 mutated. trans-sulfonamide-platinum 70-96 P53 Homo sapiens 190-194 28231799-5 2017 METHODS: We aimed to compare the cytotoxic effects of cisplatin and a trans-sulfonamide-platinum-complex (TSPC), in two human melanoma cell lines that differ in their TP53 status: SK-MEL-5, TP53 wild type, and SK-MEL-28, TP53 mutated. trans-sulfonamide-platinum 70-96 P53 Homo sapiens 190-194 10037682-0 1999 Long term lithium treatment suppresses p53 and Bax expression but increases Bcl-2 expression. Lithium 10-17 P53 Homo sapiens 39-42 27550999-3 2017 Here, we evaluated the antitumor effect of a novel small-molecule inhibitor of the MDM2-p53 interaction (MI-773) combined with cisplatin in patient-derived xenograft (PDX) ACC tumors.Experimental Design: Therapeutic strategies with MI-773 and/or cisplatin were evaluated in SCID mice harboring PDX ACC tumors (UM-PDX-HACC-5) and in low passage primary human ACC cells (UM-HACC-2A, -2B, -5, -6) in vitro The effect of therapy on the fraction of cancer stem cells (CSC) was determined by flow cytometry for ALDH activity and CD44 expression.Results: Combined therapy with MI-773 with cisplatin caused p53 activation, induction of apoptosis, and regression of ACC PDX tumors. 2-methyl-4-isothiazolin-3-one 105-107 P53 Homo sapiens 88-91 10769646-10 2000 All of the cell lines studied, CEM/0 (wt) and the ara-C resistant clones, showed functional p53 protein. Cytarabine 50-55 P53 Homo sapiens 92-95 10769646-11 2000 The cell treatment with 0.1, 1 and 10 microM ara-C for 48 hours showed increased p53 protein expression in most of these lines. Cytarabine 45-50 P53 Homo sapiens 81-84 27894814-7 2017 Building upon LASAGNA-search and kinetics binding assay, p53 was found to be a potential transcription factor for PTPN11. lasagna 14-21 P53 Homo sapiens 57-60 10585590-4 2000 Moreover, expression of wt-p53 in MCF7/Adr cells induced the production of reactive oxygen intermediates (ROIs) and caused glutathione (GSH) depletion, indicating disturbances in the cellular redox state. reactive oxygen intermediates 75-104 P53 Homo sapiens 27-30 10082308-3 1999 METHODS: We report here a parallel flow cytometric method for semiquantitative detection of p53 protein and apoptosis (percent of apoptotic cells) in a pre-B leukemic cell line (NALM-6) exposed to various antitumor agents (2.35 microg/ml etoposide; 0.175 microg/ml FCE296; 0.4 microg/ml FCE624; and 1.5 microg/ml L-PAM). fce296 265-271 P53 Homo sapiens 92-95 9927185-3 1999 When treated with N-(phosphonacetyl)-L-aspartate (PALA), which inhibits pyrimidine nucleotide synthesis, leading to synthesis of damaged DNA from highly unbalanced dNTP pools, p53-null cells enter mitosis after they have completed DNA replication, but cells with wild-type p53 do not, revealing that p53 also mediates a checkpoint that monitors the quality of newly replicated DNA. Pyrimidine Nucleotides 72-93 P53 Homo sapiens 176-179 27637603-10 2017 CONCLUSIONS: The presence of serum p53 antibody can be used as a novel, noninvasive predictor of the pathological tumor response to NAC with DCF in ESCC patients. nac 132-135 P53 Homo sapiens 35-38 9819415-4 1998 It is predicted that LMB should inhibit nuclear-cytoplasmic shuttling by MDM2 and subsequently stabilize p53. leptomycin B 21-24 P53 Homo sapiens 105-108 9819415-10 1998 In addition, LMB reduced E6"s ability to degrade p53 in the absence of MDM2, demonstrating that complete degradation of p53 by E6 requires nuclear export and therefore likely occurs in cytoplasmic proteasomes. leptomycin B 13-16 P53 Homo sapiens 49-52 9819415-10 1998 In addition, LMB reduced E6"s ability to degrade p53 in the absence of MDM2, demonstrating that complete degradation of p53 by E6 requires nuclear export and therefore likely occurs in cytoplasmic proteasomes. leptomycin B 13-16 P53 Homo sapiens 120-123 10611334-3 1999 Here, the highly sensitive ligation-mediated PCR was employed to quantify, at nucleotide resolution, the repair of UVB-induced cyclobutane pyrimidine dimers (CPDs) in genetically p53-deficient Li-Fraumeni skin fibroblasts, as well as in human lung fibroblasts expressing the human papillomavirus (HPV) E6 oncoprotein that functionally inactivates p53. cyclobutane pyrimidine 127-149 P53 Homo sapiens 179-182 10575010-0 1999 Benzo[a]pyrene activates the human p53 gene through induction of nuclear factor kappaB activity. Benzo(a)pyrene 0-14 P53 Homo sapiens 35-38 10575010-2 1999 In the present study, the effect of a potent lung cancer carcinogen, benzo[a]pyrene (B[a]P) on p53 expression was investigated. Benzo(a)pyrene 69-83 P53 Homo sapiens 95-98 10543945-1 1999 In human skin cancers, more than 30 % of all mutations in the p53 gene are transitions at dipyrimidines within the sequence context CpG, i.e. 5"-TCG and 5"-CCG, found at several mutational hotspots. 5"-ccg 153-159 P53 Homo sapiens 62-65 9753464-0 1998 Phosphorylation of the C-terminal sites of human p53 reduces non-sequence-specific DNA binding as modeled with synthetic peptides. Peptides 121-129 P53 Homo sapiens 49-52 10582657-15 1999 Induction of p53 levels was observed in WHCO3 cells exposed to GLA, AA, PGA2, indomethacin and the combination of indomethacin and GLA or AA. gamma-Linolenic Acid 63-66 P53 Homo sapiens 13-16 27888811-3 2017 Overexpression of mutated p53 with reduced or abolished function is often connected to resistance to standard medications, including cisplatin, alkylating agents (temozolomide), anthracyclines, (doxorubicin), antimetabolites (gemcitabine), antiestrogenes (tamoxifen) and EGFR-inhibitors (cetuximab). Temozolomide 163-175 P53 Homo sapiens 26-29 10582657-15 1999 Induction of p53 levels was observed in WHCO3 cells exposed to GLA, AA, PGA2, indomethacin and the combination of indomethacin and GLA or AA. prostaglandin A2 72-76 P53 Homo sapiens 13-16 14634277-3 1999 Four-day treatment with L-745,337 caused a concentration-dependent inhibition of cell growth (IC50: 0.9 mM) associated with the induction of p21WAF-1/cip1 and an increase in the proportion of apoptotic nuclei (EC50: 0.1 and 0.34 mM, respectively) while reducing the levels of m273-p53 (IC50: 0.2 mM). l-745 24-29 P53 Homo sapiens 281-284 9748583-13 1998 Parry, Enhanced restriction site mutation (RSM) analysis of 1, 2-dimethylhydrazine-induced mutations, using endogenous p53 intron sequences, Mutagenesis 12 (1997) pp. 1,2-Dimethylhydrazine 60-82 P53 Homo sapiens 119-122 9658074-9 1998 Using biotinylated peptides, we show that phosphorylation of Ser15 alone inhibits p53-TFIID interaction. Peptides 19-27 P53 Homo sapiens 82-85 14634277-6 1999 We conclude that high concentrations of L-745,337 and sodium salicylate inhibit colon cancer cell growth by a mechanism unrelated to cyclooxygenase inhibition that may involve p53-independent induction of the tumor suppressor p21WAF-1/cip1. l-745 40-45 P53 Homo sapiens 176-179 28052008-8 2017 Taken together, combination of metformin and 2-deoxyglucose reverses MDR of MCF-7/Dox cells by recovering p53 function and increasing doxorubicin accumulation. Deoxyglucose 45-59 P53 Homo sapiens 106-109 9714716-1 1998 The ability of Cu(II) and Fe(III) to promote site-specific DNA damage in the presence of endogenous reductants was investigated by using 32P-5"-end-labeled DNA fragments obtained from the human p53 tumor suppressor gene and the c-Ha-ras-1 protooncogene. cu(ii) 15-21 P53 Homo sapiens 194-197 28116660-8 2017 Moreover, 10 and 20 mug/mL Sal B reduced the expression levels of p53, increased the Bcl-2/Bax ratio and inhibited the caspase-3 activity in ox-LDL-treated HUVECs (P<0.05). sal 27-30 P53 Homo sapiens 66-69 9667752-6 1998 Phenol, diethylstilbestrol and ethylacrylate also induced increases in cellular p53. ethyl acrylate 31-44 P53 Homo sapiens 80-83 9610719-6 1998 Elevated c-myc and p53 expression appears to be responsible for the time-dependent accumulation of apoptotic cells after prolonged 2-DG treatment. Deoxyglucose 131-135 P53 Homo sapiens 19-22 10389978-5 1999 All seven HCCs with a p53 mutation from Qidong and three of five from Shanghai had the aflatoxin-associated point mutation with a G to T transversion at codon 249, position 3. Aflatoxins 87-96 P53 Homo sapiens 22-25 10037682-9 1999 These results strongly suggest that lithium-induced Bcl-2 up-regulation and p53 and Bax down-regulation play a prominent role in neuroprotection against excitotoxicity. Lithium 36-43 P53 Homo sapiens 76-79 28957796-10 2017 In 8505c cells transfected with wild-type p53, treatment with radioiodine resulted in increased radioiodine uptake and increased apoptotic cell death compared with 8505c cells harboring the p53 mutation. Iodine-131 62-73 P53 Homo sapiens 42-45 10100719-13 1999 In particular, the greater activity of DACH-acetato-Pt in cisplatin-resistant wild-type p53 ovarian tumor models can be ascribed to its ability to more efficiently induce p53 protein and activate p53 functions. (diaminocyclohexane)(diacetato)(dichloro)platinum 39-54 P53 Homo sapiens 88-91 10100719-13 1999 In particular, the greater activity of DACH-acetato-Pt in cisplatin-resistant wild-type p53 ovarian tumor models can be ascribed to its ability to more efficiently induce p53 protein and activate p53 functions. (diaminocyclohexane)(diacetato)(dichloro)platinum 39-54 P53 Homo sapiens 171-174 10100719-13 1999 In particular, the greater activity of DACH-acetato-Pt in cisplatin-resistant wild-type p53 ovarian tumor models can be ascribed to its ability to more efficiently induce p53 protein and activate p53 functions. (diaminocyclohexane)(diacetato)(dichloro)platinum 39-54 P53 Homo sapiens 171-174 9605744-3 1998 Using a UvrABC incision method, we have found that cytosine methylation greatly enhances guanine alkylation at all CpG sites in the p53 gene by a variety of carcinogens, including benzo(a)pyrene diol epoxide, benzo(g)chrysene diol epoxide, aflatoxin B1 8,9-epoxide, and N-acetoxy-2-acetylaminofluorene. Acetoxyacetylaminofluorene 270-301 P53 Homo sapiens 132-135 9580640-0 1998 Role of wild-type p53 on the antineoplastic activity of temozolomide alone or combined with inhibitors of poly(ADP-ribose) polymerase. Temozolomide 56-68 P53 Homo sapiens 18-21 9580640-6 1998 Treatment with TZM concentrations not toxic for the cells transduced with the control vector (p53-cells), induced apoptosis in p53+ cells. Temozolomide 15-18 P53 Homo sapiens 94-97 9580640-6 1998 Treatment with TZM concentrations not toxic for the cells transduced with the control vector (p53-cells), induced apoptosis in p53+ cells. Temozolomide 15-18 P53 Homo sapiens 127-130 28957796-10 2017 In 8505c cells transfected with wild-type p53, treatment with radioiodine resulted in increased radioiodine uptake and increased apoptotic cell death compared with 8505c cells harboring the p53 mutation. Iodine-131 62-73 P53 Homo sapiens 190-193 9499413-6 1998 We propose that Ad12 infection, actinomycin D and araC all induce a similar or identical global damage arrest signal (perhaps a modification or altered conformation of p53) that preferentially interferes with metaphase condensation of the RNU1 and RNU2 loci. Cytarabine 50-54 P53 Homo sapiens 168-171 10202240-7 1999 The presence of peripheral stem cell (PSC) products was found to decrease the effect of Adv-p53 on TC clonogenic growth, suggesting that PSC products could compete with TC for infection by recombinant Adv. Technetium 99-101 P53 Homo sapiens 92-95 10202240-9 1999 We conclude that a 4-hour incubation of stem cell products (2 x 10(8)/ml) with 4 x 10(11) Adv-p53 particles is sufficient to completely purge TC with no effect on hematopoietic cell function. Technetium 142-144 P53 Homo sapiens 94-97 9468547-14 1998 Thus, BP-induced aberrant proliferation is inhibited by the natural phytochemicals in part due to regulation of cell cycle progression and induction of p53 dependent apoptosis. Benzo(a)pyrene 6-8 P53 Homo sapiens 152-155 28957796-10 2017 In 8505c cells transfected with wild-type p53, treatment with radioiodine resulted in increased radioiodine uptake and increased apoptotic cell death compared with 8505c cells harboring the p53 mutation. Iodine-131 96-107 P53 Homo sapiens 42-45 9468185-5 1998 p53 gene transfer reduced thymidine incorporation of VSMCs stimulated by platelet-derived growth factor-BB (P<.001). vsmcs 53-58 P53 Homo sapiens 0-3 9864421-0 1999 Penclomedine-induced DNA fragmentation and p53 accumulation correlate with reproductive cell death in colorectal carcinoma cells with altered p53 status. penclomedine 0-12 P53 Homo sapiens 142-145 9864421-3 1999 We previously reported that telomerase positive colorectal carcinoma (RKO) cells with abrogated p53 function were more sensitive to penclomedine than were telomerase positive cells with wild-type p53. penclomedine 132-144 P53 Homo sapiens 96-99 28957796-11 2017 CONCLUSION: In summary, transfection with wild-type p53 can increase the therapeutic effect of radioiodine by regulating the expression of the NIS. Iodine-131 95-106 P53 Homo sapiens 52-55 9864421-4 1999 The present study demonstrates that significant differences in DNA fragmentation in response to penclomedine were observed in RKO cells lacking functional p53 compared with RKO cells with normal p53 function. penclomedine 96-108 P53 Homo sapiens 155-158 9864421-4 1999 The present study demonstrates that significant differences in DNA fragmentation in response to penclomedine were observed in RKO cells lacking functional p53 compared with RKO cells with normal p53 function. penclomedine 96-108 P53 Homo sapiens 195-198 9864421-6 1999 RKO cells with functional p53 respond to penclomedine treatment with a dose-dependent increase in p53 protein levels. penclomedine 41-53 P53 Homo sapiens 26-29 9864421-6 1999 RKO cells with functional p53 respond to penclomedine treatment with a dose-dependent increase in p53 protein levels. penclomedine 41-53 P53 Homo sapiens 98-101 9346961-1 1997 We have shown previously that Li-Fraumeni syndrome fibroblasts homozygous for p53 mutations are deficient in the removal of UV-induced cyclobutane pyrimidine dimers from genomic DNA, but still proficient in the transcription-coupled repair pathway (Ford, J. M., and Hanawalt, P. C. (1995) Proc. cyclobutane pyrimidine 135-157 P53 Homo sapiens 78-81 9346961-8 1997 Cells homozygous for p53 mutations were deficient in the repair of both photoproducts, whereas cells heterozygous for mutant p53 exhibited normal repair of 6-4 photoproducts, but decreased initial rates of removal of cyclobutane pyrimidine dimers, compared with normal cells. cyclobutane pyrimidine 217-239 P53 Homo sapiens 125-128 9864421-9 1999 These studies suggest that penclomedine may have a therapeutic advantage in killing cells that have abrogated p53 function. penclomedine 27-39 P53 Homo sapiens 110-113 29130967-4 2017 RESULTS: Mutant p53 cells exhibited increased expression of the C/EBP homologous protein (CHOP), glucose-regulated protein 78 (GRP78), and inositol-requiring enzyme-1alpha (IRE1alpha). Inositol 139-147 P53 Homo sapiens 16-19 9865721-4 1998 The iron chelator deferoxamine induced both HIF-1alpha and p53, but p53 up-regulation could still be detected in HIF-1alpha-deficient cells, suggesting that mechanisms other than HIF-1alpha activation contribute to oxygen-regulated p53 induction. Deferoxamine 18-30 P53 Homo sapiens 59-62 9346961-11 1997 The regulated expression of wild-type p53 resulted in the recovery of normal levels of repair of both cyclobutane pyrimidine dimers and 6-4 photoproducts in genomic DNA, but did not alter the transcription-coupled repair of cyclobutane pyrimidine dimers. cyclobutane pyrimidine 102-124 P53 Homo sapiens 38-41 9346961-11 1997 The regulated expression of wild-type p53 resulted in the recovery of normal levels of repair of both cyclobutane pyrimidine dimers and 6-4 photoproducts in genomic DNA, but did not alter the transcription-coupled repair of cyclobutane pyrimidine dimers. cyclobutane pyrimidine 224-246 P53 Homo sapiens 38-41 9282168-3 1997 Western blot analysis demonstrated the expression of wt p53 in H-358 cells following infection with rAAVp53. raavp53 100-107 P53 Homo sapiens 56-59 28193070-4 2016 After magnetic capture of the modified MBs onto screen-printed carbon working electrodes, the amperometric signal using the system hydroquinone/H2O2 was related to the levels of p53-autoantibodies in the sample. hydroquinone 131-143 P53 Homo sapiens 178-181 21590120-2 1997 Pentoxifylline has recently been shown to sensitize breast cancer cells in which the wild-type p53 function was abrogated to cisplatin-induced apoptosis. Pentoxifylline 0-14 P53 Homo sapiens 95-98 21590120-7 1997 Pentoxifylline increased the amount of radiation-induced DNA fragmentation and apoptosis in p53-defective U251 and LN-Z308 cells. Pentoxifylline 0-14 P53 Homo sapiens 92-95 9843965-0 1998 A p53-dependent S-phase checkpoint helps to protect cells from DNA damage in response to starvation for pyrimidine nucleotides. Pyrimidine Nucleotides 104-126 P53 Homo sapiens 2-5 27989139-10 2016 The modulation of RAD51 is correlated with p53 level, which suggests p53 has a role in TCBQ-induced RAD51 clearance. tetrachlorobenzoquinone 87-91 P53 Homo sapiens 43-46 9808524-7 1998 Of 216 pieces near or adjacent to p53- tumors, p53+ frequencies were 25% of BCH, 25% of DYS and 0% of CIS. bis(cyclohexylammonium)sulfate 76-79 P53 Homo sapiens 47-50 9808574-9 1998 These data demonstrate that flavopiridol has significant in vitro activity against human CLL cells through activation of caspase-3, which appears to occur independently of bcl-2 modulation, the presence of IL-4, or p53 status. alvocidib 28-40 P53 Homo sapiens 215-218 9176489-1 1997 We demonstrate here that synthetic 22-mer peptide 46, corresponding to the carboxy-terminal amino acid residues 361-382 of p53, can activate specific DNA binding of wild-type p53 in vitro and can restore the transcriptional transactivating function of at least some mutant p53 proteins in living cells. Peptides 42-49 P53 Homo sapiens 123-126 9176489-1 1997 We demonstrate here that synthetic 22-mer peptide 46, corresponding to the carboxy-terminal amino acid residues 361-382 of p53, can activate specific DNA binding of wild-type p53 in vitro and can restore the transcriptional transactivating function of at least some mutant p53 proteins in living cells. Peptides 42-49 P53 Homo sapiens 175-178 27989139-10 2016 The modulation of RAD51 is correlated with p53 level, which suggests p53 has a role in TCBQ-induced RAD51 clearance. tetrachlorobenzoquinone 87-91 P53 Homo sapiens 69-72 9176489-1 1997 We demonstrate here that synthetic 22-mer peptide 46, corresponding to the carboxy-terminal amino acid residues 361-382 of p53, can activate specific DNA binding of wild-type p53 in vitro and can restore the transcriptional transactivating function of at least some mutant p53 proteins in living cells. Peptides 42-49 P53 Homo sapiens 175-178 27934110-6 2016 Next we evaluated the performance of the biosensor in HepG2 cells by treatment with ginkgolic acid, a drug that reduces p53 sumoylation, as well as trichostatin A, a potential inducer of p53 sumoylation by enhancement of its nuclear export. ginkgolic acid 84-98 P53 Homo sapiens 120-123 9065745-0 1997 Effect of penclomedine (NSC-338720) on telomere fusions, chromatin blebbing, and cell viability with and without telomerase activity and abrogated p53 function. penclomedine 10-22 P53 Homo sapiens 147-150 9065745-8 1997 In addition, telomerase positive colorectal carcinoma cells with abrogated p53 (RC-10.3 cells) were more sensitive to penclomedine than were telomerase positive cells with wild-type p53 (RKO cells). penclomedine 118-130 P53 Homo sapiens 75-78 9065745-9 1997 These studies suggest that penclomedine may have a therapeutic advantage in killing tumor cells that are positive for telomerase activity and defective in p53 function. penclomedine 27-39 P53 Homo sapiens 155-158 9739169-1 1998 We previously reported that deferoxamine, an iron chelating agent, induced p53 and cell accumulation in the G1 phase of ML-1 cells in the same way as the DNA damaging agent, etoposide. Deferoxamine 28-40 P53 Homo sapiens 75-78 9726816-5 1998 In contrast, PDTC, DDTC, and ammonium dithiocarbamate (ADTC) did not induce apoptosis; rather they led to the induction of p53 and p21 followed by G1/S arrest. adtc 55-59 P53 Homo sapiens 123-126 9703875-0 1998 Increased p21/WAF-1 and p53 protein levels following sequential three drug combination regimen of fludarabine, cytarabine and docetaxel induces apoptosis in human leukemia cells. Cytarabine 111-121 P53 Homo sapiens 24-27 9698467-2 1998 The possibility that such an agent could be directed specifically against p53-defective tumor cells led us to study the new methylxanthine, Lisofylline, for its ability to sensitize ovary cancer cells to cis-diamminedichloroplatinum(II) (CDDP). methylxanthine 124-138 P53 Homo sapiens 74-77 27913471-7 2016 These recently approved drugs (ibrutinib, idelalisib, and venetoclax) are reporting excellent outcomes, including patients with high-risk disease such as 17p deletion (17p-) or TP53 mutations (TP53mut). ibrutinib 31-40 P53 Homo sapiens 177-181 8952546-11 1996 Immunohistochemistry of FLS cultured in chamber slides localized the p53 to the cytoplasm of most resting FLS, with nuclear staining in only 10.7 +/- 2.4%. CHEMBL1232769 24-27 P53 Homo sapiens 69-72 27198718-2 2016 Ibrutinib, a Bruton"s tyrosine kinase inhibitor is approved for relapsed/refractory and del(17p)/TP53 mutated chronic lymphocytic leukemia. ibrutinib 0-9 P53 Homo sapiens 97-101 8957493-6 1996 RESULTS: p53 mutations occurred in 11 (61%) patients with TCV compared with two (11%) in control group (p = 0.05). Trichloroethylene 58-61 P53 Homo sapiens 9-12 8957493-10 1996 CONCLUSIONS: TCV was associated with a significantly higher rate of p53 positivity than common papillary carcinoma. Trichloroethylene 13-16 P53 Homo sapiens 68-71 9704902-2 1998 As a tumor promoter, heptachlor induces human myeloblastic leukemia cells to differentiate, and also down-regulates the tumor suppressor gene p53 in human immune cells. Heptachlor 21-31 P53 Homo sapiens 142-145 9735599-6 1998 The induction of wild type p53 protein by addition of IPTG did not significantly increased radiosensitivity. Isopropyl Thiogalactoside 54-58 P53 Homo sapiens 27-30 9610719-3 1998 Moreover, 2-DG appears to restore the normal half-life of the tumor suppressor gene product p53, because the protein is strongly up-regulated after HPV 18 E6/E7 suppression. Deoxyglucose 10-14 P53 Homo sapiens 92-95 8900110-7 1996 Cells lacking the c-abl gene also responded to ara-C and MMS with increases in p53 levels and induction of p21. Cytarabine 47-52 P53 Homo sapiens 79-82 27075340-10 2016 Furthermore, AgNP-induced apoptosis was found dependent on the overproduction of reactive oxygen species (ROS) and affecting of MAPKs and AKT signaling and DNA damage-mediated p53 phosphorylation to advance HePG-2 cells apoptosis. agnp 13-17 P53 Homo sapiens 176-179 8832894-0 1996 Preferential formation of benzo[a]pyrene adducts at lung cancer mutational hotspots in P53. Benzo(a)pyrene 26-40 P53 Homo sapiens 87-90 9563650-2 1998 When the p53 tumor suppressor gene was used, 4-nitro-2-aminophenol caused Cu(II)-dependent piperidine-labile sites at poly G sequences. cu(ii) 74-80 P53 Homo sapiens 9-12 9548807-0 1998 Induction of p53 by the concerted actions of aziridine and quinone moieties of diaziquone. quinone 59-66 P53 Homo sapiens 13-16 9548807-6 1998 Diaziquone (AZQ), an anticancer agent, and its derivatives, diaziridinequinone (DZQ) and methyldiaziridinequinone (MeDZQ), induced p53 in a dose- and time-dependent manner as measured by the electrophoretic mobility shift assay. diaziridinequinone 60-78 P53 Homo sapiens 131-134 27907160-7 2016 Further, AS1411 induced cell apoptosis, which was prevented by silencing of p53 and overexpression of Bcl-2. AGRO 100 9-15 P53 Homo sapiens 76-79 27777210-8 2016 Both RITA and TMZ, especially the latter, significantly increased the expressions of p53, p21, puma, and other apoptosis-associated genes to accelerate apoptosis and inhibit the growth and colony formation of U87 cells, and the effect was more obvious with a combined treatment. Temozolomide 14-17 P53 Homo sapiens 85-88 9525497-9 1998 The results demonstrate that human colon and cervical cancer cells characterized by a mutated or disrupted p53 (i.e. not transfected) are radiosensitized by PTX, which alleviates the postirradiation G2/M-phase block. Pentoxifylline 157-160 P53 Homo sapiens 107-110 8921985-5 1996 The most significant finding is that more than 50% of HCC patients from high aflatoxin exposure areas such as southern Africa and Qidong, China harboured a codon 249 G to T transversion in the p53 tumor suppressor gene, which is found to be consistent with the mutagenic specificity of AFB1 observed in vitro. Aflatoxins 77-86 P53 Homo sapiens 193-196 8706243-3 1996 Sublines that were resistant to melphalan, pyrazafurin, mitoxantrone, etoposide and PALA all retained expression of wild-type p53. pyrazafurin 43-54 P53 Homo sapiens 126-129 7586197-6 1995 Treatment of PBLs with 2.5 microM of (+/-)-anti-BPDE and 1 mM of 3-aminobenzamide, an inhibitor of the DNA strand break-dependent enzyme poly(ADP-ribose) polymerase, resulted in increased p53 levels, in comparison to cells treated with (+/-)-anti-BPDE alone. (+/-)-anti- 37-48 P53 Homo sapiens 188-191 9414172-4 1997 The recently developed individual biochemical and molecular markers of aflatoxin exposure, i.e., aflatoxin-albumin adducts in blood and a specific GC to TA transversion mutation in codon 249 of the p53 gene (249ser p53 mutation) in hepatocellular carcinomas, permit a better quantitative estimation of aflatoxin exposure in different populations of the world. Aflatoxins 71-80 P53 Homo sapiens 198-201 27580721-6 2016 P53 inhibitors can block the apoptosis induced by both ZIKVC and ZIKVM in hNPCs, with higher potency against ZIKVC-induced apoptosis. zikvc 55-60 P53 Homo sapiens 0-3 9433478-6 1997 Our results indicate that p53 accumulation followed by transcriptional activation of genes implicated in growth arrest is triggered in TTD/XP-D cells by the persistence of cyclobutane pyrimidine dimers, which are known to block transcription, on the transcribed strands of active genes. cyclobutane pyrimidine 172-194 P53 Homo sapiens 26-29 7641180-0 1995 Beta-lapachone-mediated apoptosis in human promyelocytic leukemia (HL-60) and human prostate cancer cells: a p53-independent response. beta-lapachone 0-14 P53 Homo sapiens 109-112 7641180-9 1995 These events are p53 independent, since PC-3 and HL-60 cells are null cells, LNCaP are wild-type, and DU-145 contain mutant p53, yet all undergo apoptosis after beta-lapachone treatment. beta-lapachone 161-175 P53 Homo sapiens 17-20 7641180-10 1995 Interestingly, beta-lapachone treatment of p53 wild type-containing prostate cancer cells (i.e., LNCaP) did not result in the induction of nuclear levels of p53 protein, as did camptothecin-treated cells. beta-lapachone 15-29 P53 Homo sapiens 43-46 7641180-11 1995 Like other Topo I inhibitors, beta-lapachone may induce apoptosis by locking Topo I onto DNA, blocking replication fork movement, and inducing apoptosis in a p53-independent fashion. beta-lapachone 30-44 P53 Homo sapiens 158-161 9661701-0 1997 Induction of fragility at the human RNU2 locus by cytosine arabinoside is dependent upon a transcriptionally competent U2 small nuclear RNA gene and the expression of p53. Cytarabine 50-70 P53 Homo sapiens 167-170 7605578-0 1995 Characterization of a murine p53ser246 mutant equivalent to the human p53ser249 associated with hepatocellular carcinoma and aflatoxin exposure. Aflatoxins 125-134 P53 Homo sapiens 70-73 27580721-6 2016 P53 inhibitors can block the apoptosis induced by both ZIKVC and ZIKVM in hNPCs, with higher potency against ZIKVC-induced apoptosis. zikvc 109-114 P53 Homo sapiens 0-3 7605578-1 1995 A mutation in the tumor suppressor p53 gene resulting in an Arg-->Ser substitution in position 249 is found frequently in human hepatocellular carcinomas associated with hepatitis B infection and with aflatoxin exposure. Aflatoxins 204-213 P53 Homo sapiens 35-38 27468725-0 2016 Dimethylfumarate inhibits melanoma cell proliferation via p21 and p53 induction and bcl-2 and cyclin B1 downregulation. Dimethyl Fumarate 0-16 P53 Homo sapiens 66-69 7664937-0 1995 Recent aflatoxin exposure and mutation at codon 249 of the human p53 gene: lack of association. Aflatoxins 7-16 P53 Homo sapiens 65-68 9278485-3 1997 Here we analyse spontaneously arising mutations at the tetranucleotide CCGG ( Msp I recognition site), at positions 14 067-14 070 of the p53 gene sequence, in three colon cancer cell lines, two with microsatellite instability and one without this characteristic. tetranucleotide 55-70 P53 Homo sapiens 137-140 9268054-7 1997 Results of this investigation show that the mechanism of G1 accumulation induced by DFO involves a p53-independent pathway and that expression of p21 protein may be regulated posttranscriptionally. Deferoxamine 84-87 P53 Homo sapiens 99-102 7664937-1 1995 Experiments were done to show whether a G to T mis-sense mutation at the third base of codon 249 of the p53 tumour suppressor gene is a "hot spot" of aflatoxin attack as suggested by the results of epidemiological studies. Aflatoxins 150-159 P53 Homo sapiens 104-107 27468725-11 2016 Interestingly, DMF induced p53 and p21 yet inhibited cyclin B1 expression in a concentration-dependent manner. Dimethyl Fumarate 15-18 P53 Homo sapiens 27-30 27468725-13 2016 The knockdown of DMF induced p53 via siRNA led to significantly reduced apoptosis but had no influence on cell cycle arrest. Dimethyl Fumarate 17-20 P53 Homo sapiens 29-32 9815799-11 1997 These results indicate that p53 overexpression in TBB specimens predicts poor prognosis and chemoresistance in advanced stage NSCLC. 2-ethylhexyl 2,3,4,5-tetrabromobenzoate 50-53 P53 Homo sapiens 28-31 27468725-15 2016 These data provide evidence that DMF inhibits melanoma proliferation by reinduction of important cell cycle inhibitors leading to a concentration-dependent G0/G1 or G2/M cell cycle arrest and induction of apoptosis via downregulation of bcl-2 and induction of p53 and PARP-1 cleavage. Dimethyl Fumarate 33-36 P53 Homo sapiens 260-263 9772449-4 1997 The TC, TG and CE contents in vascular AS tissues in p53 gene mutation group were higher than those in non-mutations group (ANOV: F = 4.56-9.97, P < 0.05-0.01, no differences in PL contents). Technetium 4-6 P53 Homo sapiens 53-56 7712469-0 1995 Disruption of p53 function sensitizes breast cancer MCF-7 cells to cisplatin and pentoxifylline. Pentoxifylline 81-95 P53 Homo sapiens 14-17 27609895-3 2016 Kras activation and Trp53 deletion in the pancreas or the lung result in pancreatic ductal adenocarinoma (PDAC) or non-small cell lung carcinoma (NSCLC), respectively, but despite the same initiating events, these tumors use branched-chain amino acids (BCAAs) differently. Amino Acids, Branched-Chain 225-251 P53 Homo sapiens 20-25 7712469-12 1995 Our results show that a combination of CDDP and pentoxifylline is capable of synergistic and preferential killing of p53-defective tumor cells that do not readily undergo apoptosis. Pentoxifylline 48-62 P53 Homo sapiens 117-120 8867673-9 1995 In addition, Mn2+ strongly promoted activation of p58c-fgr and p53/56lyn without additional stimuli. Manganese(2+) 13-17 P53 Homo sapiens 63-66 9812584-3 1997 Lanthanum chloride, cerium chloride and mixed rare-earth chloride at levels of 0.5 to 1.5 mmol/L could inhibit obviously growth of cancer cells and change cell morphology and microtubule structure of PAMC82, similar to that of normal cells, their colony-forming ability lowered in soft agar, and expression of tumor suppressor gene p53, p16 and p21 increased and that of gene nm23 lowered. lanthanum chloride 0-18 P53 Homo sapiens 332-335 9163674-9 1997 It appears that, in contrast to the frequently reported G-->T transversions in codon 249 of the p53 gene in primary hepatomas in aflatoxin-exposed humans, the failure to detect Ha-ras mutations in these tumours is not due to an inability of aflatoxin B1 to activate this proto-oncogene. Aflatoxins 132-141 P53 Homo sapiens 99-102 27609895-3 2016 Kras activation and Trp53 deletion in the pancreas or the lung result in pancreatic ductal adenocarinoma (PDAC) or non-small cell lung carcinoma (NSCLC), respectively, but despite the same initiating events, these tumors use branched-chain amino acids (BCAAs) differently. Amino Acids, Branched-Chain 253-258 P53 Homo sapiens 20-25 27321910-7 2016 The stabilization of p53 by nutlin-3a abolished butaprost-mediated cell death protection. butaprost 48-57 P53 Homo sapiens 21-24 9102461-7 1997 The annealing activity of p53 is almost abolished in the presence of magnesium indicating that it can be sharply regulated in vitro and, in principle, could also be regulated in vivo. Magnesium 69-78 P53 Homo sapiens 26-29 25765771-4 2016 METHODS: The RDP-p53 fusion proteins are expressed in Escherichia coli, and they are labeled with FITC and rhodamine B by chemical modification. Fluorescein-5-isothiocyanate 98-102 P53 Homo sapiens 17-20 9006107-2 1996 A high rate of mutations in the p53 tumor suppressor gene in hepatocellular carcinomas of predominantly hepatitis B virus (HBV) carrier patients has been recently related to dietary aflatoxin. Aflatoxins 182-191 P53 Homo sapiens 32-35 9006107-9 1996 Overall, our findings indicate that in woodchucks and in ground squirrels exposure to aflatoxin may affect the development of p53 mutations less than in humans. Aflatoxins 86-95 P53 Homo sapiens 126-129 7923176-2 1994 Recently, a broad range of mutations in the p53 tumor suppressor gene has been reported in human HCCs, predominantly from hepatitis B virus carriers in areas with either high or low levels of exposure to dietary aflatoxin. Aflatoxins 212-221 P53 Homo sapiens 44-47 7923176-12 1994 In view of the considerably lower apparent rate of mutations in comparison to human HCCs, we suggest a less important role for aflatoxin in the induction of p53 mutations in HCCs of ground squirrels. Aflatoxins 127-136 P53 Homo sapiens 157-160 27576884-11 2016 However, only p53 overexpression was associated with predicting CSS independently of tumor stage.&nbsp. nbsp 102-106 P53 Homo sapiens 14-17 7930673-9 1994 Dithranol (1 microgram/microliter, n = 8), sodium dodecylsulphate (5%, n = 4), and retinoic acid (0.5%, n = 4), applied for 48 h, caused erythema, significantly increased p53 protein levels (p < 0.05), and also increased p53 mRNA. Anthralin 0-9 P53 Homo sapiens 171-174 7930673-9 1994 Dithranol (1 microgram/microliter, n = 8), sodium dodecylsulphate (5%, n = 4), and retinoic acid (0.5%, n = 4), applied for 48 h, caused erythema, significantly increased p53 protein levels (p < 0.05), and also increased p53 mRNA. Anthralin 0-9 P53 Homo sapiens 224-227 8076368-0 1994 Hyperphosphorylation of p53 induced by benzene, toluene, and chloroform. Benzene 39-46 P53 Homo sapiens 24-27 9118908-0 1996 Carcinogenic potential of benzene and toluene when evaluated using cyclin-dependent kinase activation and p53-DNA binding. Benzene 26-33 P53 Homo sapiens 106-109 9118908-4 1996 Kinase activation and subsequent hyperphosphorylation of pRb105 and p53 by benzene or toluene may be responsible for their growth promotional effects, but it does not account for increased potential of benzene to induce cancer. Benzene 75-82 P53 Homo sapiens 68-71 9118908-6 1996 Benzene increased p53-DNA site-specific DNA binding in RLE cells compared to control levels or the effects of toluene. Benzene 0-7 P53 Homo sapiens 18-21 9118908-7 1996 Increased p53-DNA site-specific binding by benzene may be caused by damage to cellular DNA. Benzene 43-50 P53 Homo sapiens 10-13 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine. Cytarabine 274-307 P53 Homo sapiens 67-70 8967975-1 1996 With the use of clonogenic survival assays, we show that wild-type p53-expressing A2780 human ovarian cell lines transfected with a dominant negative mutant p53 gene (codon 143, valine to alanine) acquired cross-resistance to ionizing radiation, cisplatin, doxorubicin, and 1-beta-D-arabinofuranosylcytosine.

Celecoxib 47-56 P53 Homo sapiens 76-79 23167625-8 2013 The effects of celecoxib on cellular growth and its association with p53 were assessed after down-regulation of p53 using synthetic interfering RNAs (siRNA) in LNCaP cells. Celecoxib 15-24 P53 Homo sapiens 69-72 23167625-10 2013 We found that celecoxib inhibited cellular growth and proliferation in a dose-dependent manner in all three cell lines; LNCaP cells with a native p53 were the most sensitive to celecoxib. Celecoxib 14-23 P53 Homo sapiens 146-149 23167625-11 2013 We observed a down- regulation effect on p53 in LNCaP cells exposed to >= 30 muM celecoxib for 72 h, but found no significant changes in the p53 levels of DU145 cells, which have a mutated p53. Celecoxib 84-93 P53 Homo sapiens 41-44 23167625-12 2013 Reduced COX-2 expression was found with decreased p53 in LNCaP and PC-3 cells that were exposed to >= 20 muM of celecoxib for 72 h, but COX-2 expression was increased in DU145 cells.

Acecainide 22-26 P53 Homo sapiens 170-173 21903092-2 2011 In the present study, we investigated the cellular mechanism underlying the degradation of p53 by NAPA. Acecainide 98-102 P53 Homo sapiens 91-94 21903092-3 2011 Knockdown of NAPA using short-hairpin RNA was shown to induce p53 accumulation and to sensitize HEK293 cells to cisplatin. Acecainide 13-17 P53 Homo sapiens 62-65 21903092-5 2011 Expression of exogenous p53 in H1299 cells was increased following knockdown of NAPA and these cells showed increased sensitivity to cisplatin-induced apoptosis. Acecainide 80-84 P53 Homo sapiens 24-27 21903092-6 2011 Notably, knockdown of NAPA induced the ubiquitination and degradation of the E3 ubiquitin ligase synoviolin and the accumulation of p53 in unstressed HEK293 cells. Acecainide 22-26 P53 Homo sapiens 132-135 21903092-7 2011 Conversely, NAPA overexpression decreased the ubiquitination and degradation of synoviolin, and reduced p53 protein level. Acecainide 12-16 P53 Homo sapiens 104-107 21903092-8 2011 Knockdown of NAPA disrupted the interaction between synoviolin and proteins that form the endoplasmic reticulum-associated degradation (ERAD) complex and in turn decreased the ability of this complex to ubiquitinate p53. Acecainide 13-17 P53 Homo sapiens 216-219 21903092-9 2011 In addition, knockdown of NAPA induced the activation of the MAPK kinases ERK, JNK and p38, but only inhibition of ERK reduced synoviolin ubiquitination and p53 accumulation. Acecainide 26-30 P53 Homo sapiens 157-160 21903092-10 2011 These results indicate that NAPA promotes resistance to cisplatin through synoviolin and the ERAD complex which together induce the degradation of p53 and thus prevent apoptosis. Acecainide 28-32 P53 Homo sapiens 147-150 21903092-11 2011 Based on these findings, we propose that the combination of cisplatin and knockdown of NAPA represents a novel and attractive strategy to eradicate p53-sensitive cancer cells. Acecainide 87-91 P53 Homo sapiens 148-151 22248668-5 2011 p53 negatively regulates glycolysis through activation of TIGAR (an inhibitor of the fructose-2,6-bisphosphate). fructose 2,6-diphosphate 85-110 P53 Homo sapiens 0-3 21660463-1 2011 In this study, in order to investigate the p53-independent function of p14ARF, we established p14ARF-inducible clones in the p53-deficient HCT cell line using the doxycycline-inducible expression system. Doxycycline 163-174 P53 Homo sapiens 125-128 21660463-2 2011 A strong cell growth inhibition and G1/S arrest were observed after doxycycline induction in p53-/-HCT cells, and the cells also exhibited an obvious decrease of DNA synthesis.

Cycloheximide 101-114 P53 Homo sapiens 46-49 12171906-3 2002 Resistance to TMZ varied most notably with the p53 status of the tumor. Temozolomide 14-17 P53 Homo sapiens 47-50 30226785-4 2018 This interaction displaces pro-apoptotic Bak and subsequently leads to intrinsic apoptosis via mimicking a p53 transcription-independent pathway. bakuchiol 41-44 P53 Homo sapiens 107-110 28970011-10 2017 Crocetin induced G1 arrest, reduced PCNA protein expression and increased the p21 and p53 accumulation in ARPE-19 cells. crocetin 0-8 P53 Homo sapiens 86-89 12171906-5 2002 The p21-related cell cycle arrest was intimately linked to TMZ toxicity because tumors with wt p53 but lacking a robust increase in p21 protein level (D-54) were resistant to TMZ.

Temozolomide 155-158 P53 Homo sapiens 136-139 12171906-9 2002 Additional pathways linking cell cycle arrest and apoptosis contribute to the efficacy of TMZ against p53 mutated glial tumors. Temozolomide 90-93 P53 Homo sapiens 102-105 12171907-8 2002 Exposure of WSU-CLL cells to 4 and 5 nM CA4P was associated with overproduction of total p53 and no dramatic change in MDM2, 14-3-3sigma, GADD45, the cyclin-dependent kinase cdc2, its inhibitory phosphorylation, the cdc2-inhibitory kinase (wee1), chk1, or cdc25 hyperphosphorylation. CA4P 40-44 P53 Homo sapiens 89-92 29113182-4 2017 Additionally, western blot analysis, Hoechst 33342 staining and cytometry analysis revealed that PAG not only inhibited the viability of HCT116 cells by suppressing the dishevelled segment polarity protein 2/glycogen synthase kinase 3 beta/beta-catenin pathway, but also induced the apoptosis of HCT116 cells by downregulating nuclear factor-kappaB p65 activity, stimulating p53 expression and promoting the generation of intracellular reactive oxygen species. pag 97-100 P53 Homo sapiens 375-378 12171907-10 2002 Our findings suggest that CA4P induces mitotic catastrophe and arrest of WSU-CLL cells mostly in the M phase independent of p53 and independent of chk1 and cdc2 phosphorylation pathways. CA4P 26-30 P53 Homo sapiens 124-127 30713659-9 2019 Furthermore, TCS activated p53 mediated apoptosis in HepG2 cells in a caspase-independent manner, while MTCS induced apoptosis was dependent on caspase. Triclosan 13-16 P53 Homo sapiens 27-30 12194756-5 2002 RESULTS: Clonogenic survival assays up to 8 Gy demonstrated that p53-defective HT-29 cells (sensitizer enhancement ratio [SER]=1.54) were sensitized by PTX (2 mM) to a significantly higher degree than p53 wild-type MCF-7 (SER=1.14) cells. Pentoxifylline 152-155 P53 Homo sapiens 65-68 12194756-5 2002 RESULTS: Clonogenic survival assays up to 8 Gy demonstrated that p53-defective HT-29 cells (sensitizer enhancement ratio [SER]=1.54) were sensitized by PTX (2 mM) to a significantly higher degree than p53 wild-type MCF-7 (SER=1.14) cells. Pentoxifylline 152-155 P53 Homo sapiens 201-204 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Oxaliplatin 89-100 P53 Homo sapiens 43-46 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Oxaliplatin 89-100 P53 Homo sapiens 261-264 29093644-15 2017 Conclusions: We concluded that crocetin combined with cisplatin exerts a synergistic anticancer effect by up-regulating the p53/p21 pathway. crocetin 31-39 P53 Homo sapiens 124-127 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Oxaliplatin 89-100 P53 Homo sapiens 261-264 12194756-6 2002 Exposure of irradiated (6 Gy) cells to PTX (2 mM) resulted in abrogation of the radiation-induced G2/M arrest in the p53-defective HT-29 and WiDr cells, whereas the p53 wild-type-expressing MCF-7 and HPR600 cells showed less significant impairment of the G2/M checkpoint. Pentoxifylline 39-42 P53 Homo sapiens 117-120 30059758-7 2018 Stable knockdown of CerS5 expression using CerS5-targeting shRNA led to an increased sensitivity of HCT-116 p53wt cells, but not of p53-/- cells, to oxaliplatin and 5-FU. Oxaliplatin 149-160 P53 Homo sapiens 108-111 30059758-10 2018 In conclusion, in p53wt colon cancer cells chemosensitivity against oxaliplatin or 5-FU could be enhanced by downregulation of CerS5 expression leading to reduced autophagy and mitochondrial respiration. Oxaliplatin 68-79 P53 Homo sapiens 18-21 12194756-6 2002 Exposure of irradiated (6 Gy) cells to PTX (2 mM) resulted in abrogation of the radiation-induced G2/M arrest in the p53-defective HT-29 and WiDr cells, whereas the p53 wild-type-expressing MCF-7 and HPR600 cells showed less significant impairment of the G2/M checkpoint.

Aflatoxins 112-121 P53 Homo sapiens 82-85 10341297-6 1999 Western blot analysis showed that auristatin-PE up-regulated the expression of wt-p53, p21WAF1 and Bax, and down-regulated Bcl-2 and cyclin B in HPAC cells, while only up-regulation of p21WAF1 and Bax was observed in PANC-1 cells. auristatin 34-44 P53 Homo sapiens 82-85 27615555-0 2017 Targeting acute myeloid leukemia with TP53-independent vosaroxin. vosaroxin 55-64 P53 Homo sapiens 38-42 27615555-1 2017 Vosaroxin is a quinolone compound that intercalates DNA and induces TP53-independent apoptosis, demonstrating activity against acute myeloid leukemia (AML) in Phase I-III trials. vosaroxin 0-9 P53 Homo sapiens 68-72 26225749-3 2015 Data from the present study demonstrated that p53 knockdown or mutation has a negative effect on metformin or phenformin-induced growth inhibition, senescence and apoptosis in breast cancer cells. Phenformin 110-120 P53 Homo sapiens 46-49 10334192-6 1999 Repair analysis of specific genomic sequences, at a single nucleotide resolution, revealed that the removal of cyclobutane pyrimidine dimers in a non-transcribed strand was significantly slower in p53-Mut and p53-Null cell lines compared with the normal p53-WT cells. cyclobutane pyrimidine 111-133 P53 Homo sapiens 197-200 28117010-3 2017 Here in this study we focus on the inhibitory effects of cationic osmolyte molecules acetylcholine chloride, and choline on an aggregation prone 10 amino acid p53 mutant peptide WRPILTIITL, and the corresponding wildtype peptide RRPILTIITL in vitro.

Benzimidazoles 29-43 P53 Homo sapiens 117-120 10334204-5 1999 (-)-anti-DB[a,l]PDE exhibited a higher binding efficiency that correlated with a significantly stronger p53 response at low concentrations of the dihydrodiol epoxides. dihydrodiol epoxides 146-166 P53 Homo sapiens 104-107 10222137-2 1999 We show that addition of leptomycin B to human primary fibroblasts increased the levels of the p53 tumor suppressor protein. leptomycin B 25-37 P53 Homo sapiens 95-98 25820822-3 2015 AFB1 can induce the mutations of genes such as tumor suppressor p53 through its metabolite AFB1-8,9-exo-epoxide, which acts as a mutagen to react with DNA. afb1-8,9-exo-epoxide 91-111 P53 Homo sapiens 64-67 27941214-6 2016 Particularly, loading with BAPTA attenuated phosphorylation of the main DNA damage response members, including ATM, 53BP1 and H2A.X and reduced activation of the p53/p21/Rb pathway in H2O2-stimulated cells. 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid 27-32 P53 Homo sapiens 162-165 28105237-6 2016 Furthermore, xanthohumol treatment (40 microM) induced SCC4 cell apoptosis, as indicated by the significant increase in activity and expression of caspase-3, caspase-8, caspase-9, PARP, p53 and AIF. xanthohumol 13-24 P53 Homo sapiens 186-189 28105237-8 2016 Taken together, the results of the present study indicated that xanthohumol mediates growth suppression and apoptosis induction, which was mediated via the suppression of Bcl-2 and Mcl-1 and activation of PARP, p53 and AIF signaling pathways. xanthohumol 64-75 P53 Homo sapiens 211-214 27535334-4 2016 In a cohort of 93 breast cancer metastatic patients, cmDetect identified ctDNA mutations in 54% of the patients and recovered somatic mutations in cancer genes EGFR, PIK3CA, and TP53 We further showed that cmDetect detected ctDNA in 89% of patients with confirmed mutated cell-free tumor DNA by plasma analyses (n = 9) within 46 pan-cancer patients. cmdetect 53-61 P53 Homo sapiens 178-182 27535334-4 2016 In a cohort of 93 breast cancer metastatic patients, cmDetect identified ctDNA mutations in 54% of the patients and recovered somatic mutations in cancer genes EGFR, PIK3CA, and TP53 We further showed that cmDetect detected ctDNA in 89% of patients with confirmed mutated cell-free tumor DNA by plasma analyses (n = 9) within 46 pan-cancer patients. cmdetect 206-214 P53 Homo sapiens 178-182 26018087-4 2015 As a consequence of disturbed iron metabolism, archazolid caused S-phase arrest, double-stranded DNA breaks, and p53 stabilization, leading to apoptosis. archazolid 47-57 P53 Homo sapiens 113-116 10222137-4 1999 Leptomycin B induced the accumulation of p53 and HDM2 in the nucleus and the appearance of discrete nuclear aggregates containing both proteins. leptomycin B 0-12 P53 Homo sapiens 41-44 26184141-4 2015 In fact, CAPE is well documented as inducing cell death by inhibiting NFkappaB and by inducing pro-apoptotic pathways (i.e., p53). caffeic acid phenethyl ester 9-13 P53 Homo sapiens 125-128 10222137-7 1999 Since HDM2 has recently been shown to contain a functional NES of the REV type, the most likely explanation for our results is that the effect of leptomycin B on HDM2 and p53 is due to the inhibition of nuclear export. leptomycin B 146-158 P53 Homo sapiens 171-174 26184141-9 2015 Similarly to CAPE, analog compounds elicited p53 activation. caffeic acid phenethyl ester 13-17 P53 Homo sapiens 45-48 26184141-11 2015 These results suggest that our new CAPE analog compounds may display the capacity to induce breast cancer apoptosis in a p53-dependent and/or independent manner. caffeic acid phenethyl ester 35-39 P53 Homo sapiens 121-124 26184141-12 2015 These CAPE analogs could thus provide new therapeutic approaches for patients with varying genotypic signatures (such as p53 mutations) in a more specific and targeted fashion. caffeic acid phenethyl ester 6-10 P53 Homo sapiens 121-124 27568863-0 2016 Subcellular mechanisms involved in apoptosis induced by aminoglycoside antibiotics: Insights on p53, proteasome and endoplasmic reticulum. Aminoglycosides 56-70 P53 Homo sapiens 96-99 10321495-0 1999 Lithium attenuates p53 levels in human neuroblastoma SH-SY5Y cells. Lithium 0-7 P53 Homo sapiens 19-22 10321495-2 1999 Because the tumor suppressor p53 is linked to cell death, we tested whether lithium administration to human neuroblastoma SH-SY5Y cells modulated the activation of p53. Lithium 76-83 P53 Homo sapiens 164-167 27564099-9 2016 Moreover, pretreatment with U0126 suppressed curcumin and cisplatin-induced upregulation of p53, p21, and p-STAT3 and downregulation of survival proteins in both cells. U 0126 28-33 P53 Homo sapiens 92-95 26146058-1 2015 OBJECTIVE: To investigate the role of apoptosis stimulating p53 binding protein 2 (ASPP2)-induced p53-dependent and p53-independent autophagy inhibition in apoptosis-promoting function of oxaliplatin (OXA). Oxaliplatin 188-199 P53 Homo sapiens 60-63 10321495-5 1999 Pretreatment with 2 mM lithium for 1 or 14 days reduced the 25 microM H7-induced elevations of nuclear p53 by 40 and 70%, respectively, and even a 14-day pretreatment with 1 mM lithium caused a significant 16% reduction. Lithium 23-30 P53 Homo sapiens 103-106 26146058-1 2015 OBJECTIVE: To investigate the role of apoptosis stimulating p53 binding protein 2 (ASPP2)-induced p53-dependent and p53-independent autophagy inhibition in apoptosis-promoting function of oxaliplatin (OXA). Oxaliplatin 201-204 P53 Homo sapiens 60-63 10321495-6 1999 Since increased nuclear p53 is a critical intermediate step in many signaling processes that culminate in cell death, attenuation of p53 activation by lithium reveals a mechanism by which lithium may support neuronal survival. Lithium 151-158 P53 Homo sapiens 133-136 27612029-0 2016 ATM/CHK/p53 Pathway Dependent Chemopreventive and Therapeutic Activity on Lung Cancer by Pterostilbene. pterostilbene 89-102 P53 Homo sapiens 8-11 27612029-4 2016 Given that ATM/CHK signaling requires p53 for its biological effects, we hypothesized that p53 is required for the anticancer effect of pterostilbene. pterostilbene 136-149 P53 Homo sapiens 38-41 10321495-6 1999 Since increased nuclear p53 is a critical intermediate step in many signaling processes that culminate in cell death, attenuation of p53 activation by lithium reveals a mechanism by which lithium may support neuronal survival. Lithium 188-195 P53 Homo sapiens 133-136 27612029-4 2016 Given that ATM/CHK signaling requires p53 for its biological effects, we hypothesized that p53 is required for the anticancer effect of pterostilbene. pterostilbene 136-149 P53 Homo sapiens 91-94 27612029-7 2016 Pterostilbene also activated ATM and CHK1/2, which are upstream of p53, in both cell lines, though pterostilbene-induced senescence was dependent on the presence of p53. pterostilbene 0-13 P53 Homo sapiens 67-70 26158294-0 2015 p53 directly activates cystatin D/CST5 to mediate mesenchymal-epithelial transition: a possible link to tumor suppression by vitamin D3.

Aflatoxins 59-69 P53 Homo sapiens 123-126 27612029-7 2016 Pterostilbene also activated ATM and CHK1/2, which are upstream of p53, in both cell lines, though pterostilbene-induced senescence was dependent on the presence of p53. pterostilbene 99-112 P53 Homo sapiens 67-70 27612029-7 2016 Pterostilbene also activated ATM and CHK1/2, which are upstream of p53, in both cell lines, though pterostilbene-induced senescence was dependent on the presence of p53. pterostilbene 99-112 P53 Homo sapiens 165-168 27612029-8 2016 Finally, pterostilbene more effectively inhibited p53-dependent cell proliferation compared to the other three stilbenoids. pterostilbene 9-22 P53 Homo sapiens 50-53 27612029-9 2016 These results strongly support the potential chemopreventive effect of pterostilbene on p53-positive cells during early carcinogenesis. pterostilbene 71-84 P53 Homo sapiens 88-91 10211969-9 1999 Quantification of the DNA content by Hoechst staining and computer-assisted image analysis showed that a fraction of the p53-positive blasts had a DNA content higher than 2N, indicating entry into the S/G2 phases. hoechst 37-44 P53 Homo sapiens 121-124 27220476-7 2016 In GM, we report somatic mutations in KIT and TP53. gm 3-5 P53 Homo sapiens 46-50 25283841-1 2015 AZD1775 targets the cell cycle checkpoint kinase Wee1 and potentiates genotoxic agent cytotoxicity through p53-dependent or -independent mechanisms. adavosertib 0-7 P53 Homo sapiens 107-110 25283841-2 2015 Here, we report that AZD1775 interacted synergistically with histone deacetylase inhibitors (HDACIs, for example, Vorinostat), which interrupt the DNA damage response, to kill p53-wild type (wt) or -deficient as well as FLT3-ITD leukemia cells in association with pronounced Wee1 inhibition and diminished cdc2/Cdk1 Y15 phosphorylation. adavosertib 21-28 P53 Homo sapiens 176-179 25434397-0 2015 Deoxycholic acid inhibits the growth of BGC-823 gastric carcinoma cells via a p53-mediated pathway. Deoxycholic Acid 0-16 P53 Homo sapiens 78-81 10100719-4 1999 In contrast, DACH-acetato-Pt was considerably more active in wild-type p53 models (IC50, 0.17-1.5 microM) than it was in mutant or null models (IC50, 2.7-11.3 microM).

Potassium Chloride 160-163 P53 Homo sapiens 90-93 25647416-5 2015 On the contrary, when the CTDBS was blocked by antibody used for immunoprecipitation, all p53-DNA complexes were completely dissociated from the p53 protein in KCl concentrations>=200 mM under the same conditions. Potassium Chloride 160-163 P53 Homo sapiens 145-148 25584615-1 2015 Crocin, a bioactive molecule of saffron, inhibited proliferation of both HCT116 wild-type and HCT116 p53(-/-) cell lines at a concentration of 10 mM. crocin 0-6 P53 Homo sapiens 101-104 8590632-1 1995 Deferoxamine (DFO)-induced iron deprivation caused an increase in p53 expression in ML-1 and Raji cells. Deferoxamine 0-12 P53 Homo sapiens 66-69 8590632-1 1995 Deferoxamine (DFO)-induced iron deprivation caused an increase in p53 expression in ML-1 and Raji cells.

Growth inhibition was observed in both cell types 6 h after addition of 10(-4)M DFO. Deferoxamine 208-211 P53 Homo sapiens 48-51 25949267-8 2015 Taken together, these findings indicate that xanthohumol-induced cell death might involve intrinsic and extrinsic apoptotic pathways, as well as downregulation of XIAP, upregulation of p53 proteins, and S phase cell cycle arrest in Ca Ski cervical cancer cells. xanthohumol 45-56 P53 Homo sapiens 185-188 8541111-4 1995 The detection of p53 in a relatively high percentage of the HCC cases in Hungary, a country in which aflatoxin contamination of the diet is rare, suggests that factors other than aflatoxin led to the accumulation or overexpression of p53 in these patients. Aflatoxins 101-110 P53 Homo sapiens 17-20 25505253-15 2015 Cell lines established from recurrent, AZD1208-resistant tumors again revealed downregulation of the p53 pathway. AZD1208 39-46 P53 Homo sapiens 101-104 25505253-16 2015 Irradiated AZD1208-treated tumors robustly upregulated p53, providing a possible mechanistic explanation for the effectiveness of combination therapy. AZD1208 11-18 P53 Homo sapiens 55-58 7557882-1 1995 The p53 gene is frequently mutated in human tumors; in hepatocellular carcinomas, there is a high frequency of a specific mutation at codon 249 in regions with significant aflatoxin exposure. Aflatoxins 172-181 P53 Homo sapiens 4-7 7554063-0 1995 p53 protein expression is correlated with benzo[a]pyrene-DNA adducts in carcinoma cell lines. Benzo(a)pyrene 42-56 P53 Homo sapiens 0-3 25260383-6 2014 Our results demonstrated that deoxyelephantopin-induced G2/M phase arrest was associated with a marked increase in the levels of p53 and p21 and a decrease in phospho-signal transducer and activator of transcription 3 (pSTAT3-Tyr705), cyclin-dependent kinase 1 (cdc2), and cyclin B1. deoxyelephantopin 30-47 P53 Homo sapiens 129-132 7554063-2 1995 We have measured benzo[a]pyrene (BP)-induced DNA damage in association with p53 expression. Benzo(a)pyrene 17-31 P53 Homo sapiens 76-79 25260383-9 2014 Our findings provided the first evidence that STAT3/p53/p21 signaling, MAPK pathway, PI3k/Akt/mTOR pathway, caspase cascades, and ROS play critical roles in deoxyelephantopin-induced G2/M phase arrest and apoptosis of SiHa cells. deoxyelephantopin 157-174 P53 Homo sapiens 52-55 7554063-2 1995 We have measured benzo[a]pyrene (BP)-induced DNA damage in association with p53 expression.

Oxaliplatin 152-163 P53 Homo sapiens 81-84 7554063-8 1995 These findings indicate that p53 protein is part of the response of the cells to BP-induced DNA damage.

Aflatoxins 102-111 P53 Homo sapiens 21-24 25286005-11 2014 This suggests that FKA"s anti-cancer activity is dependent on the p53 status. BENZYL-CARBAMIC ACID [8-DEETHYL-ASCOMYCIN-8-YL]ETHYL ESTER 19-22 P53 Homo sapiens 66-69 7955067-8 1994 To demonstrate the program, the mutational spectra of single base substitutions in the p53 gene are compared in (i) bladder cancers from smokers and non-smokers, (ii) small-cell lung cancers, non-small-cell lung cancers and colon cancers and (iii) hepatocellular carcinomas from high- and low-aflatoxin exposure groups. Aflatoxins 293-302 P53 Homo sapiens 87-90 25115399-5 2014 We also showed that Bcl-XL and Bak can substitute for Bcl-w and Bax, respectively, regulating complex-I activity and supporting the cytoplasmic function of p53; nuclear p53 also suppresses complex-I activity by inducing Bax expression. bakuchiol 31-34 P53 Homo sapiens 156-159 8058315-0 1994 Immunochemical analysis of the interaction of p53 with MDM2;--fine mapping of the MDM2 binding site on p53 using synthetic peptides.

Lopinavir 76-85 P53 Homo sapiens 176-179 24411335-5 2014 The results of an inverted fluorescence microscopy, flow cytometry (FCM) and western blotting methods demonstrated that PC-3 prostate cancer cells treated with EGFP-p53/PEI/PAH-Cit/AuNP-CS expressed higher levels of GFP than cells treated with EGFP-p53/PEI. aunp 181-185 P53 Homo sapiens 249-252 24952138-0 2014 Phenethyl isothiocyanate induces DNA damage-associated G2/M arrest and subsequent apoptosis in oral cancer cells with varying p53 mutations. phenethyl isothiocyanate 0-24 P53 Homo sapiens 126-129 24952138-4 2014 PEITC inhibited the growth of OC2, SCC4, and SCC25 cells (functional p53 mutants) in a dose-dependent manner with low toxicity to normal cells. phenethyl isothiocyanate 0-5 P53 Homo sapiens 69-72 24952138-10 2014 These results provide new insights into the critical roles of both GSH redox stress and p53 in the regulation of PEITC-induced G2/M cell cycle arrest and apoptosis in OSCCs. phenethyl isothiocyanate 113-118 P53 Homo sapiens 88-91 8390289-2 1993 As Senegal is a country where liver cancer incidence is one of the highest in the world and where people are highly exposed to aflatoxin, we screened 15 liver cancer samples from this country for mutation at codon 249 of the p53 gene. Aflatoxins 127-136 P53 Homo sapiens 225-228 23474763-9 2014 A novel small-molecule CH1 inhibitor, CH1iB, reactivates p53 and potentiates the anticancer activity of cis-platinum in HPV-positive HNSCC cells. ch1ib 38-43 P53 Homo sapiens 57-60 25395712-5 2014 Western-blotting was applied to detect P53 and PTEN protein expression in the cells treated with cactus polysaccharides. cactus polysaccharides 97-119 P53 Homo sapiens 39-42 8393124-6 1993 These results suggest a role for other environmental factors, such as aflatoxin, in the etiology of p53 mutation in hepatocellular carcinoma in Oriental patients. Aflatoxins 70-79 P53 Homo sapiens 100-103 25395712-8 2014 Furthermore, cactus polysaccharides induced growth arrest and apoptosis may be due to the increase of P53 and phosphatase and tension homolog deleted on chromosome ten (PTEN) protein. Polysaccharides 20-35 P53 Homo sapiens 102-105 24905957-7 2014 VIP effects could be blocked by cell incubation with a specific p53 inhibitor, cyclin pifithrin-alpha hydrobromide (CPFT-alphaH). cpft-alphah 116-127 P53 Homo sapiens 64-67 24333670-2 2014 The detailed mechanisms of caffeine in tumor suppression via tumor suppressor protein p53 remain unclear. Caffeine 27-35 P53 Homo sapiens 86-89 7583984-5 1993 In addition, the tumor suppressor gene p53 is frequently mutated in aflatoxin-induced hepatoma. Aflatoxins 68-77 P53 Homo sapiens 39-42 24333670-4 2014 In this study, we investigated how caffeine modulated cell cycle arrest and apoptosis via the expression of various alternatively spliced p53 isoforms. Caffeine 35-43 P53 Homo sapiens 138-141 24333670-5 2014 Caffeine reduced p53alpha expression and induced the expression of p53beta, which contains an alternatively spliced p53 C-terminus. Caffeine 0-8 P53 Homo sapiens 17-20 24333670-5 2014 Caffeine reduced p53alpha expression and induced the expression of p53beta, which contains an alternatively spliced p53 C-terminus. Caffeine 0-8 P53 Homo sapiens 67-70 24333670-7 2014 Serine/arginine-rich splicing factor 3 was a promising candidate for the serine/arginine-rich splicing factors responsible for the alternative splicing of p53 in response to caffeine treatment. Caffeine 174-182 P53 Homo sapiens 155-158 25036040-10 2014 Trichostatin A and MS-275 (both HDAC inhibitors) inhibited the downstream pathway of HDAC1 and caused cell growth arrest via activation of p53 and p21; the effects of digoxigenin were totally opposite. entinostat 19-25 P53 Homo sapiens 139-142 1332921-7 1992 They support the suggestion of a possible link between dietary exposure to aflatoxin and selective G to T mutations at codon 249 of the p53 gene. Aflatoxins 75-84 P53 Homo sapiens 136-139 24880464-0 2014 Selective tumor cell killing by triptolide in p53 wild-type and p53 mutant ovarian carcinomas. triptolide 32-42 P53 Homo sapiens 46-49 24880464-0 2014 Selective tumor cell killing by triptolide in p53 wild-type and p53 mutant ovarian carcinomas. triptolide 32-42 P53 Homo sapiens 64-67 24880464-10 2014 This study shows that triptolide selectively kills ovarian cancer cells with different p53 status predominantly through regulating the coordinate and dynamic cellular processes of proliferation and apoptosis, thereby making it a promising chemotherapeutic agent against a broad spectrum of ovarian carcinomas. triptolide 22-32 P53 Homo sapiens 87-90 24968304-10 2014 These results suggested that nilotinib can inhibit MDM2 and induce a p53-independent apoptosis pathway by downregulating XIAP; thus, nilotinib can treat not only Ph+, but also Ph- ALL patients whose cancer cells overexpress MDM2. nilotinib 29-38 P53 Homo sapiens 69-72 23821376-0 2014 Lack of KRAS, NRAS, BRAF and TP53 mutations improves outcome of elderly metastatic colorectal cancer patients treated with cetuximab, oxaliplatin and UFT. Oxaliplatin 134-145 P53 Homo sapiens 29-33 24333670-8 2014 In addition to p53-dependent functions, multiple target genes of serine/arginine-rich splicing factor 3 suggest that caffeine can regulate epithelial-mesenchymal-transition and hypoxic conditions to inhibit the survival of tumor cells. Caffeine 117-125 P53 Homo sapiens 15-18 24239715-10 2014 There were significant decreases in the expression levels of p53, p21, cyclin D1 and PCNA in AA SFs treated with rhEndostatin, and a significant increase in CDK4 expression. rhendostatin 113-125 P53 Homo sapiens 61-64 24239715-12 2014 This is partly due to the inhibitory effect of rhEndostatin on cyclin D1 and PCNA by a p53-p21-CDK4-independent mechanism. rhendostatin 47-59 P53 Homo sapiens 87-90 1279184-0 1992 Mutations of p53 gene in hepatocellular carcinoma: roles of hepatitis B virus and aflatoxin contamination in the diet. Aflatoxins 82-91 P53 Homo sapiens 13-16 25379568-11 2014 Moreover, LY29002, a PI-3K inhibitor, restored promotion of HRS by VorinostatSAHA in the p53 mutant U118 cells to levels similar to the p53 wild type cells. ly29002 10-17 P53 Homo sapiens 89-92 24584189-7 2014 Overexpression of PIAS3 in the A549 wt p53-expressing cell line was found to significantly increase the half-life of p53 in the presence of cycloheximide, an inhibitor of protein synthesis. Cycloheximide 140-153 P53 Homo sapiens 39-42 24584189-7 2014 Overexpression of PIAS3 in the A549 wt p53-expressing cell line was found to significantly increase the half-life of p53 in the presence of cycloheximide, an inhibitor of protein synthesis. Cycloheximide 140-153 P53 Homo sapiens 117-120 1279184-2 1992 These reports suggested an association of p53 mutations with high levels of aflatoxin in the diet. Aflatoxins 76-85 P53 Homo sapiens 42-45 1279184-5 1992 PURPOSE: The purpose of this study was to evaluate the relationship of p53 gene mutation to high or low levels of aflatoxin in the diet and to HBV infection. Aflatoxins 114-123 P53 Homo sapiens 71-74 1279184-11 1992 CONCLUSION: Mutations of the tumor suppressor gene p53 in hepatocellular carcinomas are not limited to patients from geographic regions where the ingestion of aflatoxin is high. Aflatoxins 159-168 P53 Homo sapiens 51-54 24493576-6 2014 Fenofibrate exhibited dose-dependent p53-independent anti-proliferative effects on HGG starting at 25 muM and pro-apoptotic effects starting at 50 muM, suggesting that the anti-proliferative actions are present only at 25 muM.

Uridine 86-93 P53 Homo sapiens 42-45 24270669-1 2014 The effect of 2-phenylethynesulfonamide (PES), which is a p53 and HSP70 inhibitor in mammalian cells, was studied on the rainbow trout (Oncorhynchus mykiss) gill epithelial cell line, RTgill-W1, in order to evaluate PES as a tool for understanding the cellular survival pathways operating in fish. 2-phenylacetylenesulfonamide 41-44 P53 Homo sapiens 58-61 24761875-8 2014 p53 PIN3 genotype was determined using electrophoresis of PCR products on 8% non-denaturing polyacrylamide gels and silver staining. polyacrylamide 92-106 P53 Homo sapiens 0-3 24573532-8 2014 In addition, PFT-alpha (a p53 inhibitor) reduced the apoptotic rates and the expression of p53, p21, caspase-3 and caspase-9 induced by tangeretin, indicating that tangeretin-induced apoptosis was p53-dependent. tangeretin 136-146 P53 Homo sapiens 26-29 24573532-8 2014 In addition, PFT-alpha (a p53 inhibitor) reduced the apoptotic rates and the expression of p53, p21, caspase-3 and caspase-9 induced by tangeretin, indicating that tangeretin-induced apoptosis was p53-dependent. tangeretin 136-146 P53 Homo sapiens 91-94 24573532-8 2014 In addition, PFT-alpha (a p53 inhibitor) reduced the apoptotic rates and the expression of p53, p21, caspase-3 and caspase-9 induced by tangeretin, indicating that tangeretin-induced apoptosis was p53-dependent. tangeretin 136-146 P53 Homo sapiens 91-94 21584516-6 1992 The data indicate that NMF treatment induces a reduction in the growth fraction of HT29 colon carcinoma cells accompanied by a reduction in c-myc, H3 histone, p53, and beta-actin gene expression, and that prolonged exposure to NMF induces elevated expresssion of alpha6/beta4 integrin receptor, These data suggest that NMF-induced reduction of the proliferative capacity supports a different "maturation status" of colon carcinoma cells which is defined by an elevated expression of the alpha6/beta4 integrin. methylformamide 23-26 P53 Homo sapiens 159-162 25114837-6 2014 Our study shows that the exclusive DGLA s free radical derivatives from C-8 oxygenation lead to cell growth inhibition, cell cycle arrest and apoptosis in the human colon cancer cell line HCA-7 colony 29, probably by up-regulating the cancer suppressor p53 and the cell cycle inhibitor p27. 8,11,14-Eicosatrienoic Acid 35-39 P53 Homo sapiens 253-256 25700359-5 2014 TEA treatment also caused significant increases in mRNA and protein levels of tumor-suppressor proteins p53 and p21, and the upregulation was attenuated by pretreatment of NAC. Tetraethylammonium 0-3 P53 Homo sapiens 104-107 2140591-3 1990 Simultaneous differential staining of p53 (identified by a FITC-labeled monoclonal antibody) versus DNA (stained with propidium iodide, PI), followed by bivariate analysis with flow cytometry (FCM) made it possible to evaluate p53 expression with respect to cell position during the cell cycle. Fluorescein-5-isothiocyanate 59-63 P53 Homo sapiens 38-41 24324808-8 2013 Among glycan traits with low heritability probe cg08392591 maps to a CpG island 5" from the ANKRD11 gene, a p53 activator on chromosome 16. Polysaccharides 6-12 P53 Homo sapiens 108-111 24595168-4 2014 METHODOLOGY/PRINCIPAL FINDINGS: We have shown here that caffeine up-regulates the tumor suppressor proteins p16, p21, p53 and Cav-1, and reduces the expression/secretion of various cytokines (IL-6, TGF-beta, SDF-1 and MMP-2), and down-regulates alpha-SMA.

Ganciclovir 259-270 P53 Homo sapiens 189-192 21858223-9 2011 However, the down-regulation of FOXM1 by either thiostrepton or U0126 required the presence of p53 in ovarian cancer cells. U 0126 64-69 P53 Homo sapiens 95-98 20708607-10 2010 In addition, oxaliplatin increased the levels of phospho-p53 (Ser-15) and total p53 proteins.

Fluorodeoxyglucose F18 12-15 P53 Homo sapiens 123-126 19015155-0 2009 Regulation of human dUTPase gene expression and p53-mediated transcriptional repression in response to oxaliplatin-induced DNA damage. Oxaliplatin 103-114 P53 Homo sapiens 48-51 19047160-6 2008 Up-regulated expression of p53/56 Lyn kinase, both at the mRNA and protein level, was found in one of the resistant cell lines and Lyn silencing by small interfering RNA restored sensitivity to nilotinib. nilotinib 194-203 P53 Homo sapiens 27-30 19127115-7 2008 Direct sequencing of TP53 gene exons 5, 6, 8, 9, and 11 revealed a ermline missense mutation, resulting in an amino acid change from an arginine to a histidine (g.13203G>A, p.R175H). ermline 67-74 P53 Homo sapiens 21-25 18959403-0 2008 Analysis of chemical shift changes reveals the binding modes of isoindolinone inhibitors of the MDM2-p53 interaction. phthalimidine 64-77 P53 Homo sapiens 101-104 18959403-1 2008 In this study we present a method for defining the binding modes of a set of structurally related isoindolinone inhibitors of the MDM2-p53 interaction. phthalimidine 98-111 P53 Homo sapiens 135-138 18959403-2 2008 This approach derives the location and orientation of isoindolinone binding, based on an analysis of the patterns of magnitude and direction of chemical shift perturbations for a series of inhibitors of the MDM2-p53 interaction. phthalimidine 54-67 P53 Homo sapiens 212-215 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. linalyl acetate 64-79 P53 Homo sapiens 218-221 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. linalyl acetate 64-79 P53 Homo sapiens 231-234 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. linalyl acetate 81-83 P53 Homo sapiens 218-221 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. linalyl acetate 81-83 P53 Homo sapiens 231-234 18707164-2 2008 The result of the calculation, based on structures from nanosecond molecular dynamics simulation, revealed that (19)Phe, (22)Leu, and (23)Trp of p53 have the strongest binding interaction with MDM2 followed by (26)Leu and (27)Pro. Phenylalanine 116-119 P53 Homo sapiens 145-148 19035306-3 2008 MATERIALS AND METHODS: The effect of the synthetic sulfonate ester, p-methoxyphenyl p-toluenesulfonate on growth inhibitory activity depending upon the estrogen-receptor (ER), p53, bcl-2 and caspase-3 status of cells was investigated by comparing its effects on three distinct human breast cancer cell lines (MCF-7, MDA-MB-231 and MDA-MB-453) and on one normal human mammary epithelial cell line (MCF-10A). sulfonate ester 51-66 P53 Homo sapiens 176-179 18850641-2 2008 Three 9-fluorenylmethoxycarbonyl (Fmoc)-labeled peptide substrates derived from the amino acid sequence of p53, i.e. Fmoc-KK(Ac)-NH(2), Fmoc-KK(Ac)L-NH(2) and Fmoc-RHKK(Ac)-NH(2), were synthesized and evaluated as substrates of the human isoenzyme SIRT1. 9-fluorenylmethoxycarbonyl 6-32 P53 Homo sapiens 107-110 18550670-3 2008 Given these attributes, we were interested in the activity of small-molecule inhibitor 9-aminoacridine (9AA), an anticancer drug that targets two important stress response pathways, NF-kappaB and p53. Aminacrine 87-102 P53 Homo sapiens 196-199 18550670-3 2008 Given these attributes, we were interested in the activity of small-molecule inhibitor 9-aminoacridine (9AA), an anticancer drug that targets two important stress response pathways, NF-kappaB and p53. Aminacrine 104-107 P53 Homo sapiens 196-199 18550670-10 2008 These results suggest that Tax-repressed p53 function in HTLV-1-transformed cells is "druggable" and can be restored by treatment with 9AA. Aminacrine 135-138 P53 Homo sapiens 41-44 18550670-11 2008 The fact that 9AA induces p53 and inhibits NF-kappaB suggests a promising strategy for the treatment of HTLV-1-transformed cells. Aminacrine 14-17 P53 Homo sapiens 26-29 18391982-0 2008 Cancer-specific enhancement of cisplatin-induced cytotoxicity with triptolide through an interaction of inactivated glycogen synthase kinase-3beta with p53. triptolide 67-77 P53 Homo sapiens 152-155 18391982-3 2008 Our results showed that a combined CDDP/triptolide therapy induced apoptosis in urothelial cancer cell lines with wild-type p53, but not in those with mutant-type p53 or normal human urothelium. triptolide 40-50 P53 Homo sapiens 124-127 18391982-4 2008 As the mechanism, triptolide suppressed CDDP-induced p53 transcriptional activity, leading to p21 attenuation, which promoted apoptosis via the activation of c-Jun N-terminal kinase (JNK) and Bax. triptolide 18-28 P53 Homo sapiens 53-56 18391982-5 2008 We further demonstrated that the functional regulation of p53 by triptolide was mediated by an intranuclear association of p53 with glycogen synthase kinase-3beta (GSK3beta), which was inactivated by protein kinase C (PKC). triptolide 65-75 P53 Homo sapiens 58-61 18391982-5 2008 We further demonstrated that the functional regulation of p53 by triptolide was mediated by an intranuclear association of p53 with glycogen synthase kinase-3beta (GSK3beta), which was inactivated by protein kinase C (PKC). triptolide 65-75 P53 Homo sapiens 123-126 18340116-4 2008 MI-43 induced the accumulation of p53 and its downstream target genes, Mdm2, p21, Noxa and Puma only in wt p53-containing cells, indicating that disruption of Mdm2-p53 binding increases p53, which is transcriptionally active. mi-43 0-5 P53 Homo sapiens 34-37 18340116-4 2008 MI-43 induced the accumulation of p53 and its downstream target genes, Mdm2, p21, Noxa and Puma only in wt p53-containing cells, indicating that disruption of Mdm2-p53 binding increases p53, which is transcriptionally active. mi-43 0-5 P53 Homo sapiens 107-110 18340116-4 2008 MI-43 induced the accumulation of p53 and its downstream target genes, Mdm2, p21, Noxa and Puma only in wt p53-containing cells, indicating that disruption of Mdm2-p53 binding increases p53, which is transcriptionally active. mi-43 0-5 P53 Homo sapiens 107-110 18340116-4 2008 MI-43 induced the accumulation of p53 and its downstream target genes, Mdm2, p21, Noxa and Puma only in wt p53-containing cells, indicating that disruption of Mdm2-p53 binding increases p53, which is transcriptionally active. mi-43 0-5 P53 Homo sapiens 107-110 18340116-5 2008 MI-43 preferentially inhibited the growth of wt p53-containing cells in a p53 dependent manner, but was much less effective in p53-null cells. mi-43 0-5 P53 Homo sapiens 48-51 18340116-5 2008 MI-43 preferentially inhibited the growth of wt p53-containing cells in a p53 dependent manner, but was much less effective in p53-null cells. mi-43 0-5 P53 Homo sapiens 74-77 18340116-5 2008 MI-43 preferentially inhibited the growth of wt p53-containing cells in a p53 dependent manner, but was much less effective in p53-null cells. mi-43 0-5 P53 Homo sapiens 74-77 18340116-9 2008 Thus, MI-43 or its analogues could be further developed as a novel class of anticancer drug for lung cancer cells harboring wt p53 as a single agent or in combination with chemo-drugs. mi-43 6-11 P53 Homo sapiens 127-130 18400537-8 2008 The SPT inhibitor ISP-1 or the ceramide synthase inhibitor fumonisin B1 led to substantial inhibition of ceramide accumulation in response to p53 up-regulation. fumonisin B1 59-71 P53 Homo sapiens 142-145 18377871-8 2008 Further characterization of the transcriptional response to wogonin in HCT116 human colon cancer cells demonstrated that PUMA induction was p53-dependent; deficiency in either p53 or PUMA significantly protected HCT116 cells against wogonin-induced apoptosis. wogonin 60-67 P53 Homo sapiens 176-179 18395372-0 2008 Verminoside- and verbascoside-induced genotoxicity on human lymphocytes: involvement of PARP-1 and p53 proteins. acteoside 17-29 P53 Homo sapiens 99-102 18243662-6 2008 On the other hand, LiCl, having no effect on caspase-3 activation, significantly increased p53 phosphorylation and apoptotic death of the normal MRC5CV1 cells while IR, activating both caspase-3 and p53, profoundly affected AT5BIVA cell death. Lithium Chloride 19-23 P53 Homo sapiens 91-94 18243662-6 2008 On the other hand, LiCl, having no effect on caspase-3 activation, significantly increased p53 phosphorylation and apoptotic death of the normal MRC5CV1 cells while IR, activating both caspase-3 and p53, profoundly affected AT5BIVA cell death. Lithium Chloride 19-23 P53 Homo sapiens 199-202 18096571-8 2008 Acrolein potentiated the effect of BP on p53 stabilization and chromatin binding. Acrolein 0-8 P53 Homo sapiens 41-44 18348731-7 2008 In this current study, we show that a small chemical molecule, 9-aminoacridine (9AA) at low concentrations, could efficiently reactivate p53 pathway and thereby restoring the p21/waf1 function. Aminacrine 63-78 P53 Homo sapiens 137-140 18348731-7 2008 In this current study, we show that a small chemical molecule, 9-aminoacridine (9AA) at low concentrations, could efficiently reactivate p53 pathway and thereby restoring the p21/waf1 function. Aminacrine 80-83 P53 Homo sapiens 137-140 18288380-9 2008 Studies on the regulation of apoptosis showed that apicidin induces the up-regulation of p53 and the downstream activation of ERK in MCF10A-ras cells. apicidin 51-59 P53 Homo sapiens 89-92 18315954-3 2008 We found that the NO donor S-nitroso-N-acetylpenicillamine (SNAP) increased apoptotic cell death in p53-deficient VSMCs compared with wild-type cells. S-Nitroso-N-Acetylpenicillamine 27-58 P53 Homo sapiens 100-103 18048073-0 2008 Central role of mitochondria and p53 in PUVA-induced apoptosis in human keratinocytes cell line NCTC-2544. puva 40-44 P53 Homo sapiens 33-36 18179182-5 2008 The cysteine residues on the exterior of the p53 molecule were derivatized for the attachment of gold nanoparticle/streptavidin conjugates capped with multiple ferrocene (Fc) groups. ferrocene 160-169 P53 Homo sapiens 45-48 18179182-5 2008 The cysteine residues on the exterior of the p53 molecule were derivatized for the attachment of gold nanoparticle/streptavidin conjugates capped with multiple ferrocene (Fc) groups. ferrocene 171-173 P53 Homo sapiens 45-48 18299254-5 2008 The results showed that the high levels of integrin beta4, p53 and ROS induced by the deprivation of serum and FGF-2 could be inhibited by the treatment of 40 microM ISO-9. iso-9 166-171 P53 Homo sapiens 59-62 18154926-6 2008 Blocking ERK1/2 activation with the upstream inhibitor U0126 inhibited NMDA-mediated p53 expression, suggesting that ERK1/2 signals drive the cells to apoptosis under these conditions. U 0126 55-60 P53 Homo sapiens 85-88 18042465-2 2008 Here, we investigated the effects of HO activity on the expression of p53 in the human retinal pigment epithelium (RPE) cell line ARPE-19. Holmium 37-39 P53 Homo sapiens 70-73 18042465-3 2008 Cobalt protoporphyrin (CoPP) induced the expression of both HO-1 and p53 without significant toxicity to the cells. cobaltiprotoporphyrin 0-21 P53 Homo sapiens 69-72 18042465-3 2008 Cobalt protoporphyrin (CoPP) induced the expression of both HO-1 and p53 without significant toxicity to the cells. cobaltiprotoporphyrin 23-27 P53 Homo sapiens 69-72 18042465-4 2008 In addition, the blockage of HO activity with the iron chelator DFO or with HO-1 siRNA inhibited the CoPP-induced expression of p53. cobaltiprotoporphyrin 101-105 P53 Homo sapiens 128-131 18042465-6 2008 Also, CoPP-induced p53 expression was not affected by the formation of reactive oxygen species (ROS). cobaltiprotoporphyrin 6-10 P53 Homo sapiens 19-22 18042465-7 2008 Based on these results, we conclude that HO activity is involved in the regulation of p53 expression in a ROS-independent mechanism, and also suggest that the expression of p53 in ARPE-19 cells is associated with heme metabolites such as biliverdin/bilirubin, carbon monoxide, and iron produced by the activity of HO. Biliverdine 238-248 P53 Homo sapiens 173-176 18540844-5 2008 This article also covers the relationship between Cr(VI)-induced oxidative stress and activation of transcription factors NF-kappaB, AP-1, p53, and hypoxia-inducible factor 1, regulation of cell cycle, and induction of apoptosis. chromium hexavalent ion 50-56 P53 Homo sapiens 139-142 17717041-3 2007 In this study, we further examined the mechanism of DHA-butyrate synergism in 1) human colon tumor (HCT-116 isogenic p53+/+ vs. p53-/-) cells and 2) primary cultures of rat colonic crypts. dha-butyrate 52-64 P53 Homo sapiens 117-120 17270229-4 2007 There are certain "hot-spots" in the p53 gene where mutations are commonly found that result in a mutated dipyrimidine site. dipyrimidine 106-118 P53 Homo sapiens 37-40 17487454-0 2007 Involvement of PPAR-gamma and p53 in DHA-induced apoptosis in Reh cells. Dihydroalprenolol 37-40 P53 Homo sapiens 30-33 17487454-6 2007 Interestingly, DHA was found to induce the expression of p53 protein in Reh cells in a PPAR-gamma-dependent manner. Dihydroalprenolol 15-18 P53 Homo sapiens 57-60 17487454-7 2007 The up-regulation of p53 protein by DHA kinetically correlated with the activation of caspase 9, caspase 3, and induction of apoptosis, suggesting a role for p53 in DHA-mediated apoptosis in Reh cells. Dihydroalprenolol 36-39 P53 Homo sapiens 21-24 17487454-7 2007 The up-regulation of p53 protein by DHA kinetically correlated with the activation of caspase 9, caspase 3, and induction of apoptosis, suggesting a role for p53 in DHA-mediated apoptosis in Reh cells. Dihydroalprenolol 165-168 P53 Homo sapiens 21-24 17487454-8 2007 Taken together, these findings suggest a new signaling pathway, DHA-PPAR-gamma-p53, in mediating the apoptotic effect of DHA in Reh cells. Dihydroalprenolol 64-67 P53 Homo sapiens 79-82 17671694-11 2007 Therefore, pGSK-3beta-ser-9 may confer the cisplatin resistance of ovarian carcinomas through the stabilization of p53 expression. pgsk-3beta 11-21 P53 Homo sapiens 115-118 17559811-5 2007 Exposure to oxaliplatin resulted in G0/G1 arrest in p53 wild-type cell lines, and in S phase in p53-mutated cell lines. Oxaliplatin 12-23 P53 Homo sapiens 52-55 17559811-5 2007 Exposure to oxaliplatin resulted in G0/G1 arrest in p53 wild-type cell lines, and in S phase in p53-mutated cell lines. Oxaliplatin 12-23 P53 Homo sapiens 96-99 17559811-7 2007 The major role of the p53-p21 pathway in oxaliplatin sensitivity was confirmed in the p53 wild-type HCT116 cell line, using siRNA duplex, and knockdown of the TAp73 protein also enhanced resistance to oxaliplatin in this cell line. Oxaliplatin 41-52 P53 Homo sapiens 22-25 17559811-7 2007 The major role of the p53-p21 pathway in oxaliplatin sensitivity was confirmed in the p53 wild-type HCT116 cell line, using siRNA duplex, and knockdown of the TAp73 protein also enhanced resistance to oxaliplatin in this cell line. Oxaliplatin 41-52 P53 Homo sapiens 86-89 17559811-9 2007 Persistent sensitivity to oxaliplatin of the p53-mutated V9P cell line was associated with oxalipatin-induced apoptosis but TAp73 was not the responsible alternative pathway. Oxaliplatin 26-37 P53 Homo sapiens 45-48 17442733-0 2007 p53-dependent NDRG1 expression induces inhibition of intestinal epithelial cell proliferation but not apoptosis after polyamine depletion. Polyamines 118-127 P53 Homo sapiens 0-3 17442733-2 2007 Our previous studies have shown that polyamine depletion stabilizes p53, resulting in inhibition of intestinal epithelial cell (IEC) proliferation, but the exact downstream targets of induced p53 are still unclear. Polyamines 37-46 P53 Homo sapiens 68-71 17442733-4 2007 The current study tests the hypothesis that induced p53 inhibits IEC proliferation by upregulating NDRG1 expression following polyamine depletion. Polyamines 126-135 P53 Homo sapiens 52-55 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Polyamines 22-32 P53 Homo sapiens 129-132 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Polyamines 22-32 P53 Homo sapiens 323-326 17442733-5 2007 Depletion of cellular polyamines by inhibiting ornithine decarboxylase (ODC) with alpha-difluoromethylornithine not only induced p53 but also increased NDRG1 transcription as indicated by induction of the NDRG1 promoter activity and increased levels of NDRG1 mRNA and protein, all of which were prevented by using specific p53 siRNA and in cells with a targeted deletion of p53. Polyamines 22-32 P53 Homo sapiens 323-326 17442733-6 2007 In contrast, increased levels of cellular polyamines by ectopic expression of the ODC gene decreased p53 and repressed expression of NDRG1. Polyamines 42-52 P53 Homo sapiens 101-104 17442733-7 2007 Consistently, polyamine depletion-induced activation of the NDRG1-promoter was decreased when p53-binding sites within the NDRG1 proximal promoter region were deleted. Polyamines 14-23 P53 Homo sapiens 94-97 17311302-7 2007 Furthermore, 80% of the most common mutants show a capacity to exert dominant-negative effect (DNE) over wild-type p53, compared to only 45% of the less frequent mutants studied, suggesting that DNE may play a role in shaping mutation patterns. dne 195-198 P53 Homo sapiens 115-118 17391696-1 2007 iASPP is an inhibitory member of ASPP (apoptosis stimulating protein of p53, or Ankyrin repeats, SH3 domain and proline-rich region contain Protein) family. aspp 1-5 P53 Homo sapiens 72-75 17390022-2 2007 cEPA inhibited the cell growth of two human leukemia cell lines, NALM-6, which is a p53-wild type, and HL-60, which is a p53-null mutant, with LD50 values of 37.5 and 12.5 microM, respectively. ethephon 0-4 P53 Homo sapiens 84-87 17390022-2 2007 cEPA inhibited the cell growth of two human leukemia cell lines, NALM-6, which is a p53-wild type, and HL-60, which is a p53-null mutant, with LD50 values of 37.5 and 12.5 microM, respectively. ethephon 0-4 P53 Homo sapiens 121-124 17292432-9 2007 Transcriptional activation of p53 and DNA fragmentation in A549 cells treated with NaVO(3) were suppressed only slightly by S15A mutation, suggesting that Ser15 phosphorylation is not essential for these responses. Vanadates 83-90 P53 Homo sapiens 30-33 17292432-10 2007 The present results showed that vanadate induces the phosphorylation of p53 at Ser15 depending on ATM, one of the members of PIKK family, in this human pulmonary epithelial cell line. Vanadates 32-40 P53 Homo sapiens 72-75 17121856-3 2007 This study investigates the action of two HDAC inhibitors, CG-1521 and trichostatin A, which stabilize Ac-Lys-373 p53 and Ac-Lys-382 p53, respectively, in LNCaP prostate cancer cells. Actinium 103-105 P53 Homo sapiens 114-117 17234782-5 2007 We found that coexpression of FUS1 and p53 by N-[1-(2,3-dioleoyloxyl)propyl]-NNN-trimethylammoniummethyl sulfate:cholesterol nanoparticle-mediated gene transfer significantly and synergistically inhibited NSCLC cell growth and induced apoptosis in vitro. n-[1-(2,3-dioleoyloxyl)propyl]-nnn-trimethylammoniummethyl sulfate 46-112 P53 Homo sapiens 39-42 17245120-7 2007 We also analyzed the antiproliferative effects of the bile pigments in an in vitro system where bilirubin/biliverdin caused p53 dependent cell cycle arrest by hypophosphorylation of the retinoblastoma tumor suppressor protein in growth factor stimulated VSMCs. Biliverdine 106-116 P53 Homo sapiens 124-127 17237273-7 2007 Western blot analyses showed that SSAT protein expression was dramatically enhanced when DENSpm was combined with oxaliplatin or 5-FU in HCT116 p53(+/+) cells. Oxaliplatin 114-125 P53 Homo sapiens 144-147 17088865-7 2006 Lovastatin attenuated the doxorubicin-induced increase in p53 as well as activation of checkpoint kinase (Chk-1) and stress-activated protein kinase/c-Jun-N-terminal kinase (SAPK/JNK). Lovastatin 0-10 P53 Homo sapiens 58-61 16905769-2 2006 This is supported by the potent activation of P53 in tumor cells by Nutlin, a cis-imidazoline that inhibits the Hdm2-P53 interaction. cis-imidazoline 78-93 P53 Homo sapiens 46-49 17034127-0 2006 Small-molecule inhibitors of the MDM2-p53 protein-protein interaction based on an isoindolinone scaffold. phthalimidine 82-95 P53 Homo sapiens 38-41 16865280-3 2006 Here, we show that ionizing radiation can promote FOXO3a (FKHRL1) transcriptional activity and protein expression level, and induce nuclear translocation of FOXO3a in Saos2, a p53-null osteosarcoma cell line. saos2 167-172 P53 Homo sapiens 176-179 16624827-5 2006 Lauryl gallate increased p53 expression only in MCF7, and upregulated p21(Cip1) and reduced cyclin D1 levels in all three cell lines. lauryl gallate 0-14 P53 Homo sapiens 25-28 16624827-9 2006 These findings suggest a potential use of lauryl gallate against tumors harboring p53 mutations and drug-resistant phenotypes. lauryl gallate 42-56 P53 Homo sapiens 82-85 16690610-0 2006 Polyamine depletion increases cytoplasmic levels of RNA-binding protein HuR leading to stabilization of nucleophosmin and p53 mRNAs. Polyamines 0-9 P53 Homo sapiens 122-125 16690610-1 2006 Polyamines are essential for maintaining normal intestinal epithelial integrity, an effect that relies, at least in part, on their ability to keep low levels of nucleophosmin (NPM) and p53 mRNAs.

Polyamines 113-122 P53 Homo sapiens 89-92 16690610-7 2006 These results indicate that polyamines modulate cytoplasmic HuR levels in intestinal epithelial cells, in turn controlling the stability of the NPM and p53 mRNAs and influencing NPM and p53 protein levels. Polyamines 28-38 P53 Homo sapiens 152-155 16690610-7 2006 These results indicate that polyamines modulate cytoplasmic HuR levels in intestinal epithelial cells, in turn controlling the stability of the NPM and p53 mRNAs and influencing NPM and p53 protein levels.

Lopinavir 55-64 P53 Homo sapiens 100-103 17310826-6 2006 In conclusion, these data show that specific HIV PIs such as lopinavir and possibly indinavir, can induce selective toxicity of HPV-transformed cervical carcinoma cells expressing wild-type p53 and may form the basis of a topically applied alternative to surgery for the treatment of HPV-related premalignant lesions of the cervix.

Oxaliplatin 0-11 P53 Homo sapiens 69-72 16227409-8 2005 In p53 mutant cells, on the other hand, oxaliplatin caused an abrupt transition from G1 to S phase and eventually resulted in G2-M arrest. Oxaliplatin 40-51 P53 Homo sapiens 3-6 16227409-10 2005 These findings suggest that p21waf1/cip1 plays a role in oxaliplatin-mediated cell cycle and growth control in p53-dependent and -independent pathways. Oxaliplatin 57-68 P53 Homo sapiens 111-114 16127747-1 2005 AIM: p53-inducible ribonucleotide reductase small subunit 2 (p53R2) encodes a 351-amino-acid peptide, which catalyzes conversion of ribonucleoside diphosphates to the corresponding deoxyribonucleotides required for DNA replication and repair. ribonucleoside diphosphates 132-159 P53 Homo sapiens 5-8 15983031-4 2005 Pancaspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone or p53 inhibitor pifithrin-alpha markedly prevented mitochondrial release of AIF, suggesting that caspases and p53 are involved in this release.

Ganciclovir 51-54 P53 Homo sapiens 83-86 15592511-9 2005 These data suggest that TK/GCV- and CD/5-FC-induced apoptosis does neither require p53 nor death receptors, but converges at a mitochondrial pathway triggered by different mechanisms of modulation of Bcl-2 proteins. Ganciclovir 27-30 P53 Homo sapiens 83-86 15546879-4 2005 Our results showed that simultaneous 5-FU and DENSPM, a spermine analogue, synergistically increased transcript levels of the polyamine catabolism enzyme spermidine/spermine N1-acetyltransferase, depleted spermine and spermidine, increased acetylated spermidine, and produced synergistic tumor cell apoptosis in both p53 wild-type and p53-null variants. Polyamines 126-135 P53 Homo sapiens 317-320 15546879-4 2005 Our results showed that simultaneous 5-FU and DENSPM, a spermine analogue, synergistically increased transcript levels of the polyamine catabolism enzyme spermidine/spermine N1-acetyltransferase, depleted spermine and spermidine, increased acetylated spermidine, and produced synergistic tumor cell apoptosis in both p53 wild-type and p53-null variants.

Ganciclovir 57-68 P53 Homo sapiens 72-75 15916863-2 2005 Here we show that the highly invasive, tumorigenic human non-small-cell-lung cancer (NSCLC) cells carrying mutated p53 alleles were transfected with herpes simplex virus-thymidine kinase (HSV-tk) cDNA and the selected clone was susceptible to exogenous ganciclovir (GCV). Ganciclovir 253-264 P53 Homo sapiens 115-118 15916863-2 2005 Here we show that the highly invasive, tumorigenic human non-small-cell-lung cancer (NSCLC) cells carrying mutated p53 alleles were transfected with herpes simplex virus-thymidine kinase (HSV-tk) cDNA and the selected clone was susceptible to exogenous ganciclovir (GCV). Ganciclovir 266-269 P53 Homo sapiens 115-118 15916863-5 2005 These data showed that the GCV-suppressed tumor cell proliferation can be coordinated by cell cycle arrest and cellular senescence in HSV-tk transfectant lacking wild-type p53.

S-Adenosylhomocysteine 122-128 P53 Homo sapiens 178-181 15292706-6 2004 Our data show that in all cell lines tested Naph-DNB was able to form ISCLs, to upregulate p53 oncosuppressor-protein and to induce apoptosis. naph 44-48 P53 Homo sapiens 91-94 15509798-9 2004 These effects are likely due to a direct effect of NAD(+) on p53, as a molecule structurally related to part of NAD(+), TDP, also inhibits p53 DNA binding, and the TDP precursor, thiamine (vitamin B(1)), inhibits intracellular p53 activity. Thiamine 179-187 P53 Homo sapiens 61-64 15509798-9 2004 These effects are likely due to a direct effect of NAD(+) on p53, as a molecule structurally related to part of NAD(+), TDP, also inhibits p53 DNA binding, and the TDP precursor, thiamine (vitamin B(1)), inhibits intracellular p53 activity. Thiamine 189-201 P53 Homo sapiens 61-64 15509798-10 2004 Niacinamide and thiamine affect two p53-regulated cellular responses to ionizing radiation: rereplication and apoptosis. Thiamine 16-24 P53 Homo sapiens 36-39 15509798-11 2004 Thus, niacinamide and thiamine form a novel basis for the development of small molecules that affect p53 function in vivo, and these results suggest that changes in cellular energy metabolism may regulate p53. Thiamine 22-30 P53 Homo sapiens 101-104 15173313-4 2004 Treatment of HeLa cells with TPT-CuCl(2) rescues the accumulation of p53 from the suppression of human papilloma virus E6, resulting in a dramatic up-regulation of Bax and Bak and down-regulation of the antiapoptotic factor Survivin. bakuchiol 172-175 P53 Homo sapiens 69-72 15802048-0 2004 Loss of p53 function in colon cancer cells results in increased phosphocholine and total choline.

Choline 190-197 P53 Homo sapiens 89-92 15802048-6 2004 These data suggest that the increased malignancy of cancer cells resulting from loss of p53 may be mediated, in part, through the choline phospholipid pathway. Choline 130-137 P53 Homo sapiens 88-91 15334062-4 2004 In addition, we observed that p53 only contributed marginally to oxaliplatin-induced cytotoxicity and was not involved in oxaliplatin resistance. Oxaliplatin 65-76 P53 Homo sapiens 30-33 15371552-0 2004 Down-regulation of MDM2 and activation of p53 in human cancer cells by antisense 9-aminoacridine-PNA (peptide nucleic acid) conjugates. 9-aminoacridine-pna 81-100 P53 Homo sapiens 42-45 15371552-4 2004 Using such lipofectamine-delivered Acr-PNA conjugates, one PNA targeting a cryptic AUG initiation site was identified that at a concentration of 2 microM caused a reduction of MDM2 levels to approximately 20% (but no reduction in mdm2 mRNA levels) and a 3-fold increase in p53 levels, whereas a 2-base mismatch control had no such effects. acr-pna 35-42 P53 Homo sapiens 273-276 34051014-6 2021 This enhanced cell death was dependent on wild-type-p53 status and autophagosome forming ability because TP53 knockout (KO) and ATG5-KO cells attenuated AZM-enhanced cytotoxicity.

Caffeine 0-8 P53 Homo sapiens 139-142 12811820-8 2003 Interestingly, the antisense oligonucleotides for p53 significantly reduced p53 expression and caffeine-induced G(2)/M phase cell cycle arrest in NB4 cells. Caffeine 95-103 P53 Homo sapiens 50-53 12811820-9 2003 These results suggest that caffeine induces cell cycle arrest and apoptosis in association with activation of p53 by a novel pathway to phosphorylate the Ser-15 residue and induction of phosphorylation of cdc 2 in leukemic cells with normal p53. Caffeine 27-35 P53 Homo sapiens 110-113 12811820-9 2003 These results suggest that caffeine induces cell cycle arrest and apoptosis in association with activation of p53 by a novel pathway to phosphorylate the Ser-15 residue and induction of phosphorylation of cdc 2 in leukemic cells with normal p53.

Polysaccharides 24-39 P53 Homo sapiens 141-144 12646262-4 2003 Administration of caffeine to G2-arrested cells induced a drastic change in cell phenotype, the nature of which depended on the status of p53. Caffeine 18-26 P53 Homo sapiens 138-141 12646262-5 2003 Flow cytometric and microscopic observations revealed that cells that either contained or lacked p53 resumed their cell cycles and entered mitosis upon caffeine treatment. Caffeine 152-160 P53 Homo sapiens 97-100 17300232-1 2007 BACKGROUND: p53 has been extensively studied in external genital carcinoma (EGC), and is frequently inactivated, but little is known about the role of the CDKN2A tumour suppressor gene in the oncogenesis of EGC.

Caffeine 29-37 P53 Homo sapiens 187-190 32451414-7 2021 RNA-sequencing analyses revealed that avasimibe suppressed the expression of CDK2, cyclin E1, CDK4, cyclin D, CDK1, cyclin B1, Aurora A, and PLK1, while induced the expression of p53, p21, p27, and GADD45A, which was validated by Western blot analysis. avasimibe 38-47 P53 Homo sapiens 179-182 12663497-5 2003 Data presented shows that, when treated with a dose of NaBt that induced significant apoptosis (4 mM for 48 h), there was an upregulation of IGFBP-3 protein in both wildtype and mutant p53 expressing cell lines. NABT 55-59 P53 Homo sapiens 185-188 12570658-7 2003 Indeed, the effect of oxaliplatin could be reduced in tumor cells expressing mutant p53.

Oxaliplatin 166-177 P53 Homo sapiens 4-7 32451414-8 2021 These results demonstrated that avasimibe induced mitochondria-dependent apoptosis in glioblastoma cells, which was associated with arresting the cell cycle at G0/G1 phase and G2/M phase by regulating the p53/p21 pathway, p53/GADD45A and Aurora A/PLK1 signaling pathways. avasimibe 32-41 P53 Homo sapiens 205-208 17045763-6 2006 The p53-functional RKO cells were higher on the cytotoxicity and cell cycle arrest at the G1 and G2/M phases than the p53-mutational SW480 cells after treatment with oxaliplatin. Oxaliplatin 166-177 P53 Homo sapiens 118-121 17045763-7 2006 Oxaliplatin inhibited the securin protein expression in the p53-functional cells but not in the p53-mutational cells. Oxaliplatin 0-11 P53 Homo sapiens 60-63 32451414-8 2021 These results demonstrated that avasimibe induced mitochondria-dependent apoptosis in glioblastoma cells, which was associated with arresting the cell cycle at G0/G1 phase and G2/M phase by regulating the p53/p21 pathway, p53/GADD45A and Aurora A/PLK1 signaling pathways. avasimibe 32-41 P53 Homo sapiens 222-225 17045763-9 2006 Nevertheless, oxaliplatin elevated the activation of p53 in both securin-wild type and securin-null cells. Oxaliplatin 14-25 P53 Homo sapiens 53-56 32638380-7 2021 For targeting mutant KRAS and reactivating mutant p53, trials have progressed to a phase III stage, i.e., the mutant-p53 reactivating drug, APR-246 is currently being investigated in patients with myelodysplastic syndrome (MDS) and the RAS inhibitor, rigosertib is also undergoing evaluation in patients with MDS.

Go 6976 9-15 P53 Homo sapiens 129-132 14622914-2 2003 In this study, we examined the role of p53 in neuronal death induced by the sodium channel modulator veratridine. Veratridine 101-112 P53 Homo sapiens 39-42 14622914-5 2003 p53-Like immunoreactivity, undetectable in neurons under control conditions, was observed in about 25% of neurons, 7 h after veratridine exposure. Veratridine 125-136 P53 Homo sapiens 0-3 14622914-8 2003 Treatments of neuronal cultures with the permeability transitory pore blockers cyclosporin A and bongkrekic acid prevented veratridine-induced p53 immunoreactivity and neuronal death, placing mitochondria upstream of veratridine-induced p53 immunoreactivity. Veratridine 123-134 P53 Homo sapiens 143-146 14622914-8 2003 Treatments of neuronal cultures with the permeability transitory pore blockers cyclosporin A and bongkrekic acid prevented veratridine-induced p53 immunoreactivity and neuronal death, placing mitochondria upstream of veratridine-induced p53 immunoreactivity. Veratridine 123-134 P53 Homo sapiens 237-240 14622914-10 2003 Antisense knockdown of p53 resulted in a significant increase in neuronal survival after veratridine treatment. Veratridine 89-100 P53 Homo sapiens 23-26 14622914-12 2003 These results together suggest that p53-expression is involved in veratridine-induced neuronal death and that p53 might be a link between toxic stimuli of different types and neuronal death.

Cycloheximide 13-26 P53 Homo sapiens 65-68 16964247-1 2006 Post-translational addition of O-linked N-acetylglucosamine (O-GlcNAc) to p53 is known to occur, but the site of O-GlcNAcylation and its effects on p53 are not understood. o-linked n-acetylglucosamine 31-59 P53 Homo sapiens 74-77 16500682-6 2006 Treatment with sulforaphane (15 microM), PEITC (10 microM), indole-3-carbinol (10 microM) and 3,3"-diindolylmethane (10 microM) induced PARP cleavage after 24 and 48 h in both 40-16 and the 379.2 cell lines, suggestive of a p53-independent mechanism of apoptosis induction. phenethyl isothiocyanate 41-46 P53 Homo sapiens 224-227 12171915-2 2002 We found that phenylethyl isothiocyanate (PEITC) was capable of inducing JNK activation and apoptosis in prostate cancer cell lines with distinct p53 statuses. phenethyl isothiocyanate 14-40 P53 Homo sapiens 146-149 12171915-2 2002 We found that phenylethyl isothiocyanate (PEITC) was capable of inducing JNK activation and apoptosis in prostate cancer cell lines with distinct p53 statuses. phenethyl isothiocyanate 42-47 P53 Homo sapiens 146-149 12176904-6 2002 Fludarabine and FCM induce p53 stabilization, but do not seem to be essential in inducing Bax and Bak conformational changes, as they are also observed in dexamethasone-treated CLL cells. Fosfomycin 16-19 P53 Homo sapiens 27-30 11925449-6 2002 Furthermore, mutation of the conserved Phe(270) within the S10 beta-sheet resulted in a mutant p53, which binds more stably to RNA.MDM2 complexes in vitro and which is strikingly hyper-ubiquitinated in vivo. Phenylalanine 39-42 P53 Homo sapiens 95-98 16434201-3 2006 Furthermore, bis-chalcone 8 exhibited a more potent inhibition of colon cancer cells expressing wild-type p53 than of an isogenic cell line that was p53-null. bis-chalcone 13-25 P53 Homo sapiens 106-109 16434201-3 2006 Furthermore, bis-chalcone 8 exhibited a more potent inhibition of colon cancer cells expressing wild-type p53 than of an isogenic cell line that was p53-null. bis-chalcone 13-25 P53 Homo sapiens 149-152 33383653-8 2020 Furthermore, cycloheximide treatment increased HO-1 abundance in p53 KO cells suggesting that p53 modulates HO-1 protein stability. Cycloheximide 13-26 P53 Homo sapiens 94-97 33288579-7 2020 Furthermore, maslinic acid elevated the levels of p-ATMSer1981, p-ATRSer428, p53, p-p53Ser151, p-H2A.XSer139, BRCA1 and PARP at 30-40 muM. maslinic acid 13-26 P53 Homo sapiens 77-80 19771269-9 2006 NaBT treatment in combination with PI3K inhibitors showed the increased expression of the CDK inhibitors p21(Cip1/Waf1) and p27(Kip1), in a p53 dependent manner, and also the increased dephosphorylation of Rb whereas there was a reduction in the expression levels of cyclin A, cyclin D1 and cyclin B1.

Acrylamide 16-26 P53 Homo sapiens 52-56 32886187-7 2020 Mutations induced by glycidamide occurred at specific TP53 codons that have also been found to be mutated in human tumours (i.e., breast, ovary, colorectal, and lung) previously associated with acrylamide exposure. Acrylamide 194-204 P53 Homo sapiens 54-58 16411021-2 2006 In the study of the molecular mechanism of this phenomenon, it was found that GnTV-AS reduced the expressions of anti-apoptotic proteins, such as phosphorylated protein kinase B and phosphorylated Bad as well as Bcl-2 and Bcl-X (L), and elevated those of pro-apoptotic proteins, including Bax, full length caspase-3 and its activated fragments as well as anti-oncoprotein p53. gntv 78-82 P53 Homo sapiens 372-375 12027749-0 2002 Isolation of streptonigrin and its novel derivative from Micromonospora as inducing agents of p53-dependent cell apoptosis.

Lovastatin 0-10 P53 Homo sapiens 96-99 16287968-3 2005 Among the compounds isolated were derivatives of 9-aminoacridine (9AA), including the antimalaria drug quinacrine, which strongly induced p53 function in RCC and other types of cancer cells.

Aminacrine 66-69 P53 Homo sapiens 138-141 12006651-2 2002 Herein, we show that human Cdc6 is rapidly destroyed by a p53-independent, proteasome-, and ubiquitin-dependent pathway during early stages of programmed cell death induced by the DNA-damaging drug adozelesin, or by a separate caspase-dependent pathway in cells undergoing apoptosis through an extrinsic pathway induced by tumor necrosis factor-alpha and cycloheximide. Cycloheximide 355-368 P53 Homo sapiens 58-61 33091670-6 2020 The docking study of the new compounds 3a-n revealed high binding scores for the new compounds toward p53 binding domain in MDM2. 3a-n 39-43 P53 Homo sapiens 102-105 16159876-6 2005 Upon mdm2 binding this motif becomes a well defined full helix turn whose hydrophobic face formed by the side chains of Ile-50, Trp-53, and Phe-54 inserts deeply into the helix binding pocket. Isoleucine 120-123 P53 Homo sapiens 128-134 11835680-0 2002 Caffeine induces TP53-independent G(1)-phase arrest and apoptosis in human lung tumor cells in a dose-dependent manner. Caffeine 0-8 P53 Homo sapiens 17-21 32958825-8 2020 However, PPARgamma deficiency inhibited cell death by blocking the ATM-p53 axis in radiation/CB11-induced radiation-resistant human NSCLC cells. cb11 93-97 P53 Homo sapiens 71-74 11835680-3 2002 Surprisingly, at a concentration of 5 mM, caffeine not only induced apoptosis by itself and acted synergistically to enhance radiation-induced apoptosis, but also induced a TP53-independent G(1)-phase arrest. Caffeine 42-50 P53 Homo sapiens 173-177 33160274-3 2020 More intriguingly, the disruption of p53 in hESCs leads to dramatic upregulation of phosphatidylcholine and decrease of total choline in both pluripotent and differentiated state of hESCs, suggesting abnormal choline metabolism in the absence of p53. Choline 96-103 P53 Homo sapiens 37-40 16308485-9 2005 The transduction of redox signals into zinc signals and vice versa affects mitochondrial functions and signaling pathways (NF-kappaB, p53, AP-1) where zinc and the zinc donor/acceptor pair metallothionein/thionein are critically involved in life and death decisions of the cell. Lys-Cys-Thr-Cys-Cys-Ala 196-204 P53 Homo sapiens 134-137 16204068-10 2005 We conclude that CPT-11 and tomudex may be more effective than 5-FU and oxaliplatin in the treatment of p53 mutant colorectal cancer tumors by sensitizing them to Fas-mediated apoptosis in a STAT1-dependent manner. Oxaliplatin 72-83 P53 Homo sapiens 104-107 16179969-1 2005 We recently identified two thiazolidin compounds, 5-[(4-methylphenyl)methylene]-2-(phenylamino)-4(5H)-thiazolone (MMPT) and 5-(2,4-dihydroxybenzylidene)-2-(phenylimino)-1,3-thiazolidin (DBPT), that inhibit the growth of human non-small-cell lung and colon cancer cells independent of P-glycoprotein and p53 status. Timonacic 27-38 P53 Homo sapiens 303-306 12509296-10 2002 Since HPV16 (E6/E7) transformed XPV cells were highly UV sensitive and not further sensitized by caffeine, it appears likely that caffeine sensitization proceeds through a p53 pathway. Caffeine 130-138 P53 Homo sapiens 172-175 33160274-3 2020 More intriguingly, the disruption of p53 in hESCs leads to dramatic upregulation of phosphatidylcholine and decrease of total choline in both pluripotent and differentiated state of hESCs, suggesting abnormal choline metabolism in the absence of p53.

Lovastatin 37-47 P53 Homo sapiens 69-72 11280728-1 2001 The p53-dependent initiation of apoptosis is accompanied by the induction of proline oxidase (POX), a mitochondrial enzyme catalyzing the conversion of proline to pyrroline-5-carboxylate with the concomitant transfer of electrons to cytochrome c. delta-1-pyrroline-5-carboxylate 163-186 P53 Homo sapiens 4-7 11313826-3 2001 Here, we report that adenoviral (Ad)-TK/GCV-induced death is p53-independent and does not involve altered CD95 or CD95L expression. Ganciclovir 40-43 P53 Homo sapiens 61-64 15219811-4 2004 ELISA assay showed that Saikosaponin D significantly increased the expression of p53 and p21/WAF1 protein, contributing to cell cycle arrest. saikosaponin D 24-38 P53 Homo sapiens 81-84 31898356-8 2020 The relative mRNA abundance of BAK, BAX, CASP3, CASP8, and TP53 and protein abundance of Bak, cleaved caspase-3, caspase-8, and P53 was activated by U73122 or inhibited by m-3M3FBS, while the relative mRNA and protein level of BCL6 showed the opposite trend. 1-(6-((3-methoxyestra-1,3,5(10)-trien-17-yl)amino)hexyl)-1H-pyrrole-2,5-dione 149-155 P53 Homo sapiens 60-63 15219811-6 2004 Taken together, our study suggests that the induction of p53 and activity of the Fas/FasL apoptotic system may participate in the antiproliferative activity of Saikosaponin D in A549 cells. saikosaponin D 160-174 P53 Homo sapiens 57-60 32605658-0 2020 A ruthenium(II)-curcumin compound modulates NRF2 expression balancing the cancer cell death/survival outcome according to p53 status. Ruthenium(II) 2-15 P53 Homo sapiens 122-125 15212949-3 2004 Decreasing phospho-ERK with the pharmacological inhibitors, PD98059 and U0126, markedly suppresses hyperoxia-stimulated phospho-p53(Ser15), p53, and p21(CIP1), and also restores the hyperoxia-reduced kinase activities of cyclin D1/E1-Cdks. U 0126 72-77 P53 Homo sapiens 128-131 15212949-3 2004 Decreasing phospho-ERK with the pharmacological inhibitors, PD98059 and U0126, markedly suppresses hyperoxia-stimulated phospho-p53(Ser15), p53, and p21(CIP1), and also restores the hyperoxia-reduced kinase activities of cyclin D1/E1-Cdks. U 0126 72-77 P53 Homo sapiens 140-143 15293391-2 2004 In this study, we prepared an inexpensive linear polyacrylamide (LPA), and successfully applied it to CE-SSCP analysis and tandem CE-SSCP/heteroduplex analysis (HA) of the P53 gene on an ABI capillary genetic analyzer. polyacrylamide 49-63 P53 Homo sapiens 172-175 11240376-11 2001 These data suggest that deoxycholate caused DNA damage in colon epithelial cells that was sufficient to trigger apoptosis in a p53-independent manner. Deoxycholic Acid 24-36 P53 Homo sapiens 127-130 32642717-4 2020 Methods: Using a well-established Sleeping Beauty (SB) transposon strategy, we injected human HGF and MET cDNA together with a short hairpin siRNA against Trp53 (SB-hHgf.Met.ShP53) into the lateral ventricle of neonatal mice to induce spontaneous glioma initiation and characterized the tumors with H&E and immunohistochemistry analysis.

Vanadates 13-21 P53 Homo sapiens 84-87 10922372-8 2000 Furthermore, vanadate-induced apoptosis occurred in cells expressing wild-type p53 (p53+/+) but was very weak in p53-deficient (p53-/-) cells. Vanadates 13-21 P53 Homo sapiens 84-87 10922372-9 2000 These results demonstrate that vanadate induces p53 activation mainly through H(2)O(2) generation, and this activation is required for vanadate-induced apoptosis. Vanadates 31-39 P53 Homo sapiens 48-51 10942736-0 2000 The role of hydroxyl radical as a messenger in Cr(VI)-induced p53 activation. chromium hexavalent ion 47-53 P53 Homo sapiens 62-65 10942736-13 2000 NADPH, which accelerated the one-electron reduction of Cr(VI) to Cr(V) and increased.OH radical generation, dramatically enhanced p53 activation. oh radical 85-95 P53 Homo sapiens 130-133 10942736-14 2000 Thus.OH radical generated from Cr(VI) reduction in A549 cells is responsible for Cr(VI)-induced p53 activation. oh radical 5-15 P53 Homo sapiens 96-99 10942736-14 2000 Thus.OH radical generated from Cr(VI) reduction in A549 cells is responsible for Cr(VI)-induced p53 activation. chromium hexavalent ion 31-37 P53 Homo sapiens 96-99 10942736-14 2000 Thus.OH radical generated from Cr(VI) reduction in A549 cells is responsible for Cr(VI)-induced p53 activation. chromium hexavalent ion 81-87 P53 Homo sapiens 96-99 15130282-5 2004 Indeed, in addition to transition-type mutations at dipyrimidine sites, G:C to T:A transversions, which may be induced by the presence of 8-oxoguanine during DNA replication, are frequently observed in the ras oncogene and p53 tumor suppressor gene in human skin cancers of sun-exposed areas and in UV-induced mouse skin cancers. dipyrimidine 52-64 P53 Homo sapiens 223-226 15004035-7 2004 By using a temperature-sensitive mutant of p53 where cytoplasmic-nuclear movement occurs by shift to permissive temperature, we show that p53 movement is impeded when p53 binding to hsp90 is inhibited by the hsp90 inhibitor radicicol. monorden 224-233 P53 Homo sapiens 43-46 15004035-7 2004 By using a temperature-sensitive mutant of p53 where cytoplasmic-nuclear movement occurs by shift to permissive temperature, we show that p53 movement is impeded when p53 binding to hsp90 is inhibited by the hsp90 inhibitor radicicol. monorden 224-233 P53 Homo sapiens 138-141 15004035-7 2004 By using a temperature-sensitive mutant of p53 where cytoplasmic-nuclear movement occurs by shift to permissive temperature, we show that p53 movement is impeded when p53 binding to hsp90 is inhibited by the hsp90 inhibitor radicicol. monorden 224-233 P53 Homo sapiens 138-141 32382022-10 2020 Conclusions: Sorafenib and Regorafenib were especially active in well-differentiated cells, with wild-type p53 and increased mitochondrial respiration. regorafenib 27-38 P53 Homo sapiens 107-110 15064743-6 2004 In contrast, abrogation of p53 function by the expression of HPV16 E6 in K1 and K2 cells either at the same time as DNhTERT or just prior to the onset of senescence allowed cells to continue growing until "crisis". dnhtert 116-123 P53 Homo sapiens 27-30 10825467-1 2000 The dietary isothiocyanates and cancer chemopreventive agents phenethyl isothiocyanate and allyl isothiocyanate and their cysteine conjugates inhibited the growth and induced apoptosis of human leukaemia HL60 (p53-) and human myeloblastic leukaemia-1 cells (p53+) in vitro. phenethyl isothiocyanate 62-86 P53 Homo sapiens 210-213 10825467-1 2000 The dietary isothiocyanates and cancer chemopreventive agents phenethyl isothiocyanate and allyl isothiocyanate and their cysteine conjugates inhibited the growth and induced apoptosis of human leukaemia HL60 (p53-) and human myeloblastic leukaemia-1 cells (p53+) in vitro. phenethyl isothiocyanate 62-86 P53 Homo sapiens 258-261 32202904-10 2020 Results showed that the expression of p-p53, p53, Bax and PUMA was upregulated after CBL0137 administration. CBLC137 85-92 P53 Homo sapiens 40-43 10867037-7 2000 Nuclear p53 protein levels were >100% higher in the ZD Opti-MEM cells than in ZA cells. opti-mem 58-66 P53 Homo sapiens 8-11 15183084-13 2004 An immunologic prozone effect was observed above 1000 ng p53 antibodies per milliliter of serum. prozone 15-22 P53 Homo sapiens 57-60 14987952-7 2004 Taken together, emodin displays effective inhibitory effects on the growth of various human hepatoma cell lines and stimulates the expression of p53 and p21 that resulted in the cell cycle arrest of HepG2/C3A cells at G(2)/M phase. Emodin 16-22 P53 Homo sapiens 145-148 32202904-10 2020 Results showed that the expression of p-p53, p53, Bax and PUMA was upregulated after CBL0137 administration. CBLC137 85-92 P53 Homo sapiens 45-48 10914555-6 2000 Treatment of cells with protein tyrosine phosphatase inhibitor vanadate blocked the p53-induced differentiation, but not that of cell death or growth arrest. Vanadates 63-71 P53 Homo sapiens 84-87 32321992-6 2020 Significant decrease of clonogenic capacity and higher apoptosis rates were also observed after ATO exposure, being cell death more pronounced (>70%) for the SHH-MB TP53-mutated. ato 96-99 P53 Homo sapiens 165-169 10809772-6 2000 In contrast, caffeine abolishes the accumulation of p53 caused by all the compounds. Caffeine 13-21 P53 Homo sapiens 52-55 14757171-7 2004 Caffeine, an ATM kinase inhibitor, inhibited these effects of genistein on Chk2, p53, and p21waf1/cip1. Caffeine 0-8 P53 Homo sapiens 81-84 15075671-2 2004 MEN15658 induces p53 accumulation, and activation of gadd-45, p21, c-fos and bcl-2 family genes in human ovarian carcinoma A2780 cell line. 2-((1,10)phenanthrolin-2-ylhydrazono)-3,4-dihydro-2H-naphthalen-1-one 0-8 P53 Homo sapiens 17-20 32321992-9 2020 Herein, we showed ATO cytotoxicity in pediatric SHH cell lines, with marked radiosensitizing effect for the MB-SHH TP53-mutated cells. ato 18-21 P53 Homo sapiens 115-119 10737899-0 2000 p53/56(lyn) antisense shifts the 1,25-dihydroxyvitamin D3-induced G1/S block in HL60 cells to S phase.

Calcitriol 66-92 P53 Homo sapiens 51-54 10815759-2 2000 Therefore, we investigated the utility of new heterodinucleoside phosphate dimers of 5-fluorodeoxyuridine (5-FdUrd) in p53-mutated and androgen-independent DU-145 human prostate tumour cells. heterodinucleoside phosphate 46-74 P53 Homo sapiens 119-122 10738214-4 2000 Phenol-chloroform-extracted DNA specimens were employed for the detection of HBV infection and p53 gene mutations. Phenol 0-6 P53 Homo sapiens 95-98 15055483-6 2004 The reduction of Cr (VI) to Cr (III) results in the formation of reactive intermediates that together with oxidative stress and oxidative tissue damage, and a cascade of cellular events including modulation of apoptosis regulatory gene p53 contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. chromium hexavalent ion 17-24 P53 Homo sapiens 236-239 15055483-6 2004 The reduction of Cr (VI) to Cr (III) results in the formation of reactive intermediates that together with oxidative stress and oxidative tissue damage, and a cascade of cellular events including modulation of apoptosis regulatory gene p53 contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. chromium hexavalent ion 308-314 P53 Homo sapiens 236-239 31278615-6 2020 Our study presents two preliminary findings: (a) in HaVSMCs, FOLFIRI treatment significantly induces oxidative damage to both DNA and protein, leading to a dramatic increase in caspase-dependent apoptotic death through P53-mediated Caspase3-dependent mitochondrial apoptosis, and results in TNF-alpha/Caspase8-mediated necrotic death, and (b) flavonoids not only regulate the expression of genes encoding antioxidant enzymes and increase DNA damage but also limit programmed and necrotic cell death processes in HaVSMCs. FOLFIRI regimen 61-68 P53 Homo sapiens 219-222 14704122-3 2004 RESULTS: The 15d-PGJ2 induced apoptosis in ECV304 endothelial cells in a dose-dependent manner (the percentage of apoptosis was enhanced from 10.0 %+/-1.3 % to 32.8 %+/-1.6 %), which was accompanied by inhibition of NF-?B and AP-1 DNA binding activity, down-regulation of c-myc, upregulation of Gadd45 and p53, and activation of p38 kinase. 9-deoxy-delta-9-prostaglandin D2 17-21 P53 Homo sapiens 306-309 14971655-3 2004 Under certain conditions, some hexavalent chromium [Cr(VI)] compounds are toxic and carcinogenic in the human respiratory tract, and we have shown that they induce apoptosis and/or cell cycle arrest in a p53-dependent fashion. chromium hexavalent ion 52-58 P53 Homo sapiens 204-207 14564515-8 2003 CONCLUSIONS: These results suggest that DCA induced up-regulation of EphA2 in colon cancer cells is due to activation of erk1/2 cascade, and is p53-independent. Deoxycholic Acid 40-43 P53 Homo sapiens 144-147 10702305-5 2000 The addition of the broad-spectrum caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-fluoromethyl ketone (zVAD-fmk) directly after transduction almost completely prevented p53-induced apoptotic cell death but did not inhibit mitochondrial cytochrome c release. Caspase Inhibitor VI 53-102 P53 Homo sapiens 170-173 10937051-8 2000 Boric acid was used for antigen retrieval on sections stored for 12 weeks at 20 degrees C. For both p53 protein and MIB1 antigen, this resulted in an extent and intensity of immunostaining equal to or higher than (MIB1) that obtained in freshly cut sections, using citrate buffer. Citric Acid 265-272 P53 Homo sapiens 100-103 10719037-0 2000 p53 mutations experimentally induced by 8-methoxypsoralen plus UVA (PUVA) differ from those found in human skin cancers in PUVA-treated patients. puva 68-72 P53 Homo sapiens 0-3 10719037-9 2000 Through a rigorous statistical test, the PUVA-induced p53 mutation spectrum appears to differ significantly (P < 0.0002) from that observed in SCC in PUVA-treated patients. puva 41-45 P53 Homo sapiens 54-57 10719037-9 2000 Through a rigorous statistical test, the PUVA-induced p53 mutation spectrum appears to differ significantly (P < 0.0002) from that observed in SCC in PUVA-treated patients. puva 153-157 P53 Homo sapiens 54-57 10738085-3 2000 RESULTS: The radiosensitizing effect of caffeine (2 mM) expressed itself as a significant decrease in surviving fraction at 2 Gy and a significant increase in alpha-values in RT112 and TE671, both with non-functional p53. Caffeine 40-48 P53 Homo sapiens 217-220 14643431-4 2003 Incubation in caffeine did not increase the percentage of cells entering the S phase 6-8h after irradiation; ATM-dependent phosphorylation of p53 and transactivation of p21(Cip1/Waf1) post-IR were resistant to caffeine. Caffeine 14-22 P53 Homo sapiens 142-145 10738085-9 2000 CONCLUSION: The data presented confirm that p53 status can be a significant determinant of the efficacy of caffeine as radiosensitizer in these tumour cell lines, and document the importance of the G2 checkpoint in this effect. Caffeine 107-115 P53 Homo sapiens 44-47 31751608-7 2020 Glyphosate decreased expression of P16 and TP53 as well as an increase in the expression of BCl2, CCND1 and P21. glyphosate 0-10 P53 Homo sapiens 43-47 10713709-8 2000 These data indicate that WR1065, a polyamine analog with thiol anti-oxidant properties, activates a cell cycle check-point involving p53. Polyamines 35-44 P53 Homo sapiens 133-136 14981925-7 2003 Apoptosis induced by CAPE or CAO is associated with increased expression of p53, p21 and c-Jun. caffeic acid phenethyl ester 21-25 P53 Homo sapiens 76-79 14580323-3 2003 Recombinant p53, purified in the presence of the reducing agent dithiothreitol (DTT), contains five free thiol groups on the surface of the protein. Dithiothreitol 64-78 P53 Homo sapiens 12-15 14580323-3 2003 Recombinant p53, purified in the presence of the reducing agent dithiothreitol (DTT), contains five free thiol groups on the surface of the protein. Dithiothreitol 80-83 P53 Homo sapiens 12-15 32027268-6 2020 Western blot analysis showed that sorafenib combined with decitabine significantly up-regulated the levels of Bax/Bcl-2, P53, C-Caspase3 and C-PARP and activated apoptosis by inhibiting PI3K-AKT pathway. decitabine 58-68 P53 Homo sapiens 121-124 14580323-9 2003 Electromobility shift assays showed that binding of oxidized p53 to DNA was enhanced upon addition of DTT, indicating that oxidation is reversible. Dithiothreitol 102-105 P53 Homo sapiens 61-64 14580323-10 2003 The possibility that oxidized p53 contained significant amounts of sulfenic (-SOH), sulfinic (-SO2H), or sulfonic acid (-SO3H) was ruled out. -so2h 94-99 P53 Homo sapiens 30-33 10690553-7 2000 This change resulted in a Val to Phe substitution and was associated with a constitutive production of high levels of p53, which was inactive as a transcriptional activator of bax and p21. Phenylalanine 33-36 P53 Homo sapiens 118-121 32027268-7 2020 CONCLUSION: Sorafenib combined with decitabine induces the apoptosis of diffuse large B-cell lymphoma cell line OCI-LY1 by inhibiting PI3K-AKT pathway and activating P53. decitabine 36-46 P53 Homo sapiens 166-169 10611293-2 1999 Here, a combination of biochemical and nuclear magnetic resonance experiments demonstrates that the activation domain of the tumor suppressor p53 has an FXXPhiPhi motif (F, Phe; X, any amino acids; Phi, hydrophobic residues) that folds into an alpha-helix upon binding to one of its targets, hTAF(II)31 (a human TFIID TATA box-binding protein-associated factor). Phenylalanine 173-176 P53 Homo sapiens 142-145 14607978-2 2003 Treatment of HeLa cells with TPT-benzimidazolethiol arrests the cell cycle at G0/G1 phase and transcriptionally downregulates HPV-encoded E6, restoring p53 expression from E6 suppression. triphenyl tin benzimidazolethiol 29-51 P53 Homo sapiens 152-155 31900123-0 2020 Rapid response of stage IV colorectal cancer with APC/TP53/KRAS mutations to FOLFIRI and Bevacizumab combination chemotherapy: a case report of use of liquid biopsy. FOLFIRI regimen 77-84 P53 Homo sapiens 54-58 10588903-5 1999 According to quantitative analysis with folded Gaussian distributions, the bending induced by p53 varied from approximately 40 degrees to 48 degrees upon decreasing of the KCl concentration from 50 mM to approximately 1 mM in the mounting buffer used for adsorption of the complexes to the carbon film surface. Potassium Chloride 172-175 P53 Homo sapiens 94-97 10574974-9 1999 These results suggest that ROS generated through Cr(VI) reduction is responsible to the early stage of apoptosis, whereas p53 contributes to the late stage of apoptosis and is responsible for the enhancement of Cr(VI)-induced apoptosis at this stage. chromium hexavalent ion 211-217 P53 Homo sapiens 122-125 31900123-3 2020 Retrospective cell free DNA testing showed that the APC/TP53/KRAS major clone responded quickly after 3 cycles of FOLFIRI + Bevacizumab. FOLFIRI regimen 114-121 P53 Homo sapiens 56-60 14527683-7 2003 When the DCI values were analyzed by regression analysis, a significant positive relationship between IkappaBalpha superrepressor and dominant-negative IKKbeta and an inverse relationship between p53 and Mdm2 were consistent with previous reports. dci 9-12 P53 Homo sapiens 196-199 32067620-12 2020 CONCLUSION: The results suggested that podophyllum derivatives containing fluorine atom in the 3-position of 2-aminopyridine could inhibit the growth of HCC harboring p53-R249S by restoring the activity of p53 with decreasing the level of c-Myc. alpha-aminopyridine 109-124 P53 Homo sapiens 167-170 12807757-3 2003 The current study examines the ability of acrolein to modulate the effect of benzo[a]pyrene (B[a]P), a major carcinogen found in smoke, on p53. Acrolein 42-50 P53 Homo sapiens 139-142 12807757-7 2003 However, acrolein treatments profoundly inhibited the DNA binding of p53 under both basal and B[a]P-induced conditions. Acrolein 9-17 P53 Homo sapiens 69-72 12807757-8 2003 Depleting glutathione with buthionine sulfoximine in B[a]P-treated cells to levels similar to those obtained with acrolein decreased p53 DNA binding substantially less than with acrolein. Acrolein 114-122 P53 Homo sapiens 133-136 12807757-9 2003 Using a p53 dual luciferase reporter assay, acrolein caused an 83% decrease in the p53 activity induced by B[a]P (1 mM for 24 h post-transfection). Acrolein 44-52 P53 Homo sapiens 8-11 12807757-9 2003 Using a p53 dual luciferase reporter assay, acrolein caused an 83% decrease in the p53 activity induced by B[a]P (1 mM for 24 h post-transfection). Acrolein 44-52 P53 Homo sapiens 83-86 10571245-2 1999 Caffeine has been shown to abrogate the S and G2 arrest in p53-defective cells and to enhance cytotoxicity, but at concentrations too toxic to administer to humans. Caffeine 0-8 P53 Homo sapiens 59-62 10590231-3 1999 This study investigated whether the mutational hot spots of the Apc and p53 genes for human colorectal cancer are mutated in dimethylhydrazine-induced colorectal neoplasms and whether dietary folate can modulate mutations in these regions. Dimethylhydrazines 125-142 P53 Homo sapiens 72-75 12807757-10 2003 The p53 protein that was immunoprecipitated after acrolein treatment was reactive with an anti-acrolein antibody indicating covalent modification. Acrolein 50-58 P53 Homo sapiens 4-7 32067620-12 2020 CONCLUSION: The results suggested that podophyllum derivatives containing fluorine atom in the 3-position of 2-aminopyridine could inhibit the growth of HCC harboring p53-R249S by restoring the activity of p53 with decreasing the level of c-Myc. alpha-aminopyridine 109-124 P53 Homo sapiens 206-209 12807757-11 2003 Results from this study suggest that acrolein can inhibit p53 DNA binding and activity by direct covalent modification as well as alteration of intracellular redox status. Acrolein 37-45 P53 Homo sapiens 58-61 10590231-12 1999 These data suggest that in the dimethylhydrazine rat model of colorectal cancer, the Apc gene is mutated in early stages, albeit to a lesser degree than observed in human colorectal cancer, whereas the mutational hot spot of the p53 gene for human colorectal cancer is not commonly mutated. Dimethylhydrazines 31-48 P53 Homo sapiens 229-232 32749126-6 2020 The effect of EGb761 on the p53 signaling pathway was further confirmed by adding pifithrin (PFT)-alpha, an inhibitor of p53. -alpha 97-103 P53 Homo sapiens 28-31 10543945-1 1999 In human skin cancers, more than 30 % of all mutations in the p53 gene are transitions at dipyrimidines within the sequence context CpG, i.e. 5"-TCG and 5"-CCG, found at several mutational hotspots. 5"-tcg 142-148 P53 Homo sapiens 62-65 32749126-6 2020 The effect of EGb761 on the p53 signaling pathway was further confirmed by adding pifithrin (PFT)-alpha, an inhibitor of p53. -alpha 97-103 P53 Homo sapiens 121-124 31680191-6 2020 Specifically, lysine 370/372/373 and 381/382/386 mutations decreased p53 stability, and lysine 305 mutation reduced p53 phosphorylation level at serine 15, while lysine 120 and 164 mutations decreased p53 acetylation level at lysine 382. cholecystokinin C-terminal flanking peptide 145-151 P53 Homo sapiens 116-119 31680191-6 2020 Specifically, lysine 370/372/373 and 381/382/386 mutations decreased p53 stability, and lysine 305 mutation reduced p53 phosphorylation level at serine 15, while lysine 120 and 164 mutations decreased p53 acetylation level at lysine 382. cholecystokinin C-terminal flanking peptide 145-151 P53 Homo sapiens 116-119 12869633-7 2003 In p53-deficient cells, little K2-5F is expressed, and thus HSV-TK is expressed, allowing the cells to be killed by ganciclovir (GCV). Ganciclovir 116-127 P53 Homo sapiens 3-6 31856867-5 2019 METHODS: We implemented a screening of a chemical library for compounds with potential to abrogate cancer cell specific mortalin-p53 interactions, and identified a new compound (named it as Mortaparib) that caused nuclear enrichment of p53 and shift in mortalin from perinuclear (typical of cancer cells) to pancytoplasmic (typical of normal cells). mortaparib 190-200 P53 Homo sapiens 129-132 12869633-7 2003 In p53-deficient cells, little K2-5F is expressed, and thus HSV-TK is expressed, allowing the cells to be killed by ganciclovir (GCV). Ganciclovir 129-132 P53 Homo sapiens 3-6 12869633-8 2003 K2-5F induced by exogenous p53 dramatically reduced the expression of HSV-TK in human embryonic kidney 293 cells, and it subsequently increased cell survival in response to GCV. Ganciclovir 173-176 P53 Homo sapiens 27-30 12869633-10 2003 Stable expression of moderate levels of p53 in Saos-2 cells was able to induce the expression of K2-5F and reduce HSV-TK expression and resulted in a modest but distinct protection from GCV toxicity. Ganciclovir 186-189 P53 Homo sapiens 40-43 12874009-3 2003 In HT1080 cells expressing a dominant-negative form of p53, treatment with etoposide still caused G(2) arrest, but the arrest could be overcome by additional treatment with caffeine, which inhibits the damage-responsive kinases ataxia telangiectasia mutated (ATM) and atm and rad3-related (ATR). Caffeine 173-181 P53 Homo sapiens 55-58 10479688-5 1999 Adenovirus-mediated delivery of p53 to cerebellar granule neurons resulted in caspase-3 (CPP32) activation followed by terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling (TUNEL) staining and loss of viability as determined by an MTT survival assay. Uridine Triphosphate 179-182 P53 Homo sapiens 32-35 10485486-6 1999 Similar concentrations of caffeine also inhibit gamma- and UV radiation-induced phosphorylation of p53 on Ser15, a modification that may be directly mediated by the ATM and ATR kinases. Caffeine 26-34 P53 Homo sapiens 99-102 12807744-3 2003 Interestingly, the methylxanthine caffeine can abrogate the p53 accumulation induced by certain DNA-damaging agents by an unknown mechanism. Caffeine 34-42 P53 Homo sapiens 60-63 31856867-5 2019 METHODS: We implemented a screening of a chemical library for compounds with potential to abrogate cancer cell specific mortalin-p53 interactions, and identified a new compound (named it as Mortaparib) that caused nuclear enrichment of p53 and shift in mortalin from perinuclear (typical of cancer cells) to pancytoplasmic (typical of normal cells). mortaparib 190-200 P53 Homo sapiens 236-239 12807744-5 2003 Caffeine inhibited the accumulation of p53 induced by leptomycin B (LMB), an inhibitor of CRM1, but not N-acetyl-leu-leu-norleucinal, a proteasome inhibitor. Caffeine 0-8 P53 Homo sapiens 39-42 12807744-6 2003 Furthermore, caffeine also inhibited the accumulation of p53 by a variety of stress-inducing agents in vivo, such as 5-fluorouracil, doxorubicin, mitomycin C, camptothecin and roscovitine. Caffeine 13-21 P53 Homo sapiens 57-60 10652599-0 1999 Mutant p53 mediated induction of cell cycle arrest and apoptosis at G1 phase by 9-hydroxyellipticine. 9-hydroxyellipticine 80-100 P53 Homo sapiens 7-10 31856867-6 2019 Biochemical and molecular assays were used to demonstrate the effect of Mortaparib on mortalin, p53 and PARP1 activities. mortaparib 72-82 P53 Homo sapiens 96-99 10652599-2 1999 Although in many cancer cells p53 is frequently mutated and loses its functions, we have proposed that mutant p53 may be involved in the anticancer mechanism of 9-hydroxy ellipticine (9HE). 9-hydroxyellipticine 161-182 P53 Homo sapiens 30-33 10652599-2 1999 Although in many cancer cells p53 is frequently mutated and loses its functions, we have proposed that mutant p53 may be involved in the anticancer mechanism of 9-hydroxy ellipticine (9HE). 9-hydroxyellipticine 161-182 P53 Homo sapiens 110-113 10652599-2 1999 Although in many cancer cells p53 is frequently mutated and loses its functions, we have proposed that mutant p53 may be involved in the anticancer mechanism of 9-hydroxy ellipticine (9HE). 9-hydroxyellipticine 184-187 P53 Homo sapiens 30-33 10652599-2 1999 Although in many cancer cells p53 is frequently mutated and loses its functions, we have proposed that mutant p53 may be involved in the anticancer mechanism of 9-hydroxy ellipticine (9HE). 9-hydroxyellipticine 184-187 P53 Homo sapiens 110-113 12963547-4 2003 Following treatment with DHT, in vivo binding of p53 to its response elements was strongly inhibited. Dihydrotestosterone 25-28 P53 Homo sapiens 49-52 31856867-8 2019 Bioinformatics analysis revealed that although Mortaparib could interact with mortalin, its binding with p53 interaction site was not stable. mortaparib 47-57 P53 Homo sapiens 105-108 31711520-9 2019 The effects of decitabine on P15INK4B and TP53 in MDS cells after inhibiting HO-1 were detected by Western blotting. decitabine 15-25 P53 Homo sapiens 42-46 12782109-9 2003 Also, t-BuOOH treatment caused an elevation in the levels of the pro-apoptotic proteins p53 and p21/WAF-1 and a reduction in the levels of the anti-apoptotic protein bcl-2 compared to their levels in control HCN1-A cells, while pretreatment with nicotinamide reduced p53 and p21/WAF-1 levels even in the presence of t-BuOOH. di-tert-butyl peroxide 6-13 P53 Homo sapiens 88-91 12782109-9 2003 Also, t-BuOOH treatment caused an elevation in the levels of the pro-apoptotic proteins p53 and p21/WAF-1 and a reduction in the levels of the anti-apoptotic protein bcl-2 compared to their levels in control HCN1-A cells, while pretreatment with nicotinamide reduced p53 and p21/WAF-1 levels even in the presence of t-BuOOH. di-tert-butyl peroxide 6-13 P53 Homo sapiens 267-270 12802789-7 2003 Our results indicate that inducible TS expression in M7TS90 cells modulates p53 and p53 target gene expression in response to TDX, but not 5-FU. raltitrexed 126-129 P53 Homo sapiens 76-79 12802789-7 2003 Our results indicate that inducible TS expression in M7TS90 cells modulates p53 and p53 target gene expression in response to TDX, but not 5-FU. raltitrexed 126-129 P53 Homo sapiens 84-87 10336811-1 1999 AIMS: To determine the incidence and prognostic value of p53 immunopositivity in resectable distal bile duct carcinoma (DBDC). dibenzyldithiocarbamate 120-124 P53 Homo sapiens 57-60 10336811-8 1999 CONCLUSIONS: This study indicates that low (0-30%) p53 expression is a favourable prognostic factor in patients with resected DBDC. dibenzyldithiocarbamate 126-130 P53 Homo sapiens 51-54 10361685-4 1999 During the induction of apoptosis by phloretin, the expression of Bax protein in B16 cells increased and the levels of p53, Bcl-2, and Bcl-XL proteins did not change. Phloretin 37-46 P53 Homo sapiens 119-122 31436301-7 2019 Silencing of DHRS2 in HCT116/Oxa cells effectively restored Oxa-sensitivity by suppressing the expression of excision repair cross-complementing group 1 protein via a p53-dependent pathway, and reversed the EMT phenotype. Oxaliplatin 29-32 P53 Homo sapiens 167-170 10082548-6 1999 Following microinjection of HaeIII into lactacystin-treated normal fibroblasts, lactacystin-induced p53 protein is phosphorylated at serine 15 and stabilized even in the presence of cycloheximide. Cycloheximide 182-195 P53 Homo sapiens 100-103 10037682-3 1999 Long term, but not acute, treatment of cultured cerebellar granule cells with LiCl induces a concentration-dependent decrease in mRNA and protein levels of proapoptotic p53 and Bax; conversely, mRNA and protein levels of cytoprotective Bcl-2 are remarkably increased. Lithium Chloride 78-82 P53 Homo sapiens 169-172 10037682-6 1999 Pretreatment with LiCl for 7 days prevents glutamate-induced increase in p53 and Bax expression and maintains Bcl-2 in an elevated state. Lithium Chloride 18-22 P53 Homo sapiens 73-76 12894503-3 2003 Caffeine, a nonspecific inhibitor of ATR, enhanced the cytotoxic effect of cisplatin, modestly decreased the p53 and p21WAF-1 response to cisplatin, and affected the cdc2-p34/cyclin B1 complex by decreasing both cyclin B1 protein accumulation and cdc2-p34 tyrosine 15 phosphorylation. Caffeine 0-8 P53 Homo sapiens 109-112 31111543-10 2019 CONCLUSIONS: The presence of aneuploidy, p53 positivity and development of HGD or adenocarcinoma on follow-up indicate that CCA likely represents a dysplastic lesion (at least LGD) and is a histological marker of neoplastic progression. 1-methylcyclohexanecarboxylic acid 124-127 P53 Homo sapiens 41-44 12648234-1 2003 Squamous cell carcinomas in psoralen-plus-ultraviolet A (PUVA) treated patients frequently exhibit p53 tumor suppressor genes and Ha-ras protooncogenes that are mutated at dipyrimidine sites and carry the ultraviolet fingerprint (i.e., C-to-T or CC-to-TT transitions). dipyrimidine 172-184 P53 Homo sapiens 99-102 12628923-9 2003 CK2 phosphoryl ates Thr155, which targets p53 to degradation by the Ub system. ates 15-19 P53 Homo sapiens 42-45 10195885-6 1999 Treating MCF-7 cells with AdHSV-tk/GCV led to the predicted increase in endogenous p53 and p21WAF1/CIP1 protein levels, and apoptosis was observed in a significant proportion of the target cell population. Ganciclovir 35-38 P53 Homo sapiens 83-86 10195885-8 1999 This latter result suggested that HSV-tk/GCV treatment can activate a strong p53-independent apoptotic response in tumor cells that lack functional p53. Ganciclovir 41-44 P53 Homo sapiens 77-80 10195885-8 1999 This latter result suggested that HSV-tk/GCV treatment can activate a strong p53-independent apoptotic response in tumor cells that lack functional p53. Ganciclovir 41-44 P53 Homo sapiens 148-151 12527938-10 2003 This type of mutated-p53 in TYS cells prevents cell death from DNA damage, and probably accumulates genetic alterations and accelerates the malignant progression of the cells by DNA damaging therapy. TYS 28-31 P53 Homo sapiens 21-24 31540454-6 2019 Apoptosis and cell cycle arrest were induced by fludioxonil (10-7-10-5 M) in the Jurkat T cells at 24 and 48 h and Ramos B cells at 48 h. Moreover, the protein levels of pro-apoptotic proteins, such as p53, BAX, and cleaved caspase 3, were increased and anti-apoptotic protein Bcl-2 was decreased by fludioxonil. fludioxonil 48-59 P53 Homo sapiens 202-205 12538356-7 2003 As expected, BPDE produced predominantly G to T transversions and simulated sunlight produced mostly C to T transitions at dipyrimidine sites in the p53 coding sequence. dipyrimidine 123-135 P53 Homo sapiens 149-152 12488329-0 2003 p53 Is required for 1,25-dihydroxyvitamin D3-induced G0 arrest but is not required for G1 accumulation or apoptosis of LNCaP prostate cancer cells. Calcitriol 20-44 P53 Homo sapiens 0-3 12183079-4 2002 In addition, AA profoundly increased protein level of p53, which was also inhibited by BAPTA/AM, an intracellular Ca(2+) chelator, TMB-8 and dantrolene. 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid 87-92 P53 Homo sapiens 54-57 10026322-8 1999 In vivo studies showed that the growth of subcutaneous tumours of p53 mutant MKN1 cells was significantly inhibited by direct injection of AdCAp53, but no significant growth inhibition was detected in the growth of p53 wild type MKN45 tumours. adcap53 139-146 P53 Homo sapiens 66-69 9886259-0 1999 Thymidine dinucleotide mimics the effect of solar simulated irradiation on p53 and p53-regulated proteins. thymidine dinucleotide 0-22 P53 Homo sapiens 75-78 9886259-0 1999 Thymidine dinucleotide mimics the effect of solar simulated irradiation on p53 and p53-regulated proteins. thymidine dinucleotide 0-22 P53 Homo sapiens 83-86 9886259-2 1999 We have previously reported that the thymidine dinucleotide (pTpT), a common target for DNA photoproduct formation by UV light, mimics many effects of UV irradiation in cultured skin-derived cells, at least in part through the activation of p53. thymidine dinucleotide 37-59 P53 Homo sapiens 241-244 9865726-5 1998 In combination with gamma-irradiation, isogranulatimide selectively kills MCF-7 cells lacking p53 function. isogranulatimide 39-55 P53 Homo sapiens 94-97 12439598-8 2002 Treatment of cells with PD98059 or UO126 after cisplatin incubation or inhibition of signaling through ERK by tetracycline-regulated expression of dominant-inhibitory ERK enhanced resistance to cisplatin in p53-negative osteosarcoma cells and reduced cisplatin-induced apoptosis. U 0126 35-40 P53 Homo sapiens 207-210 31183995-10 2019 CONCLUSION: In C26 colorectal adenocarcinoma mEHT-induced irreversible cell stress can activate both caspase-dependent apoptosis and p21waf1 mediated growth arrest pathways, likely to be driven by the upregulated nuclear p53 protein. meht 45-49 P53 Homo sapiens 221-224 12376477-7 2002 Tangeretin also increased the content of the Cdk inhibitor p21 protein and this effect correlated with the elevation in p53 levels. tangeretin 0-10 P53 Homo sapiens 120-123 9808165-0 1998 DNA adduct levels associated with p53 induction and delay of MCF-7 cells in S phase after exposure to benzo[g]chrysene dihydrodiol epoxide enantiomers. benzo[g]chrysene dihydrodiol epoxide 102-138 P53 Homo sapiens 34-37 11245004-2 1998 METHODS: The tumor suppressing effects of inducing apoptosis and inhibition of the formation of G418 resistant colonies of the specific point mutated p53 minigene in a structural expression vector on a human cancer cell line PG with preexisting dominant negative p53 were preliminarily verified. antibiotic G 418 96-100 P53 Homo sapiens 150-153 11245004-2 1998 METHODS: The tumor suppressing effects of inducing apoptosis and inhibition of the formation of G418 resistant colonies of the specific point mutated p53 minigene in a structural expression vector on a human cancer cell line PG with preexisting dominant negative p53 were preliminarily verified. antibiotic G 418 96-100 P53 Homo sapiens 263-266 12371145-5 2002 In view of its upregulation in many tumors and transcriptional inactivation function of p53, its potential use in biotechnology and biomedicine is discussed. biomedicine 132-143 P53 Homo sapiens 88-91 31059712-0 2019 Daucosterol disturbs redox homeostasis and elicits oxidative-stress mediated apoptosis in A549 cells via targeting thioredoxin reductase by a p53 dependent mechanism. lyoniside 0-11 P53 Homo sapiens 142-145 9743293-7 1998 All four compounds can induce apoptosis in A2780, which is reduced in mutant p53 transfectants, as measured using the terminal DNA transferase-mediated b-d UTP nick end labelling (TUNEL) assay. Uridine Triphosphate 156-159 P53 Homo sapiens 77-80 31379992-10 2019 Also, the analysis correlated with induced cell death elucidated that concurrent treatment of polysaccharide plus paclitaxel had a further anti-cancer effect against A2780cp cells mainly through restoration of p53 and mitochondrial apoptosis cell death induction. Polysaccharides 94-108 P53 Homo sapiens 210-213 9713990-1 1998 We established a colon cancer cell line SW480-LOWTP53-1 carrying a wild-type TP53 transgene that is inducible under control of the lactose operon. Lactose 131-138 P53 Homo sapiens 49-53 12208600-3 2002 The reduction of Cr(VI) to Cr(III) results in the formation of reactive intermediates that together with oxidative stress oxidative tissue damage and a cascade of cellular events including modulation of apoptosis regulatory gene p53, contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. chromium hexavalent ion 17-23 P53 Homo sapiens 229-232 12208600-3 2002 The reduction of Cr(VI) to Cr(III) results in the formation of reactive intermediates that together with oxidative stress oxidative tissue damage and a cascade of cellular events including modulation of apoptosis regulatory gene p53, contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. chromium hexavalent ion 302-308 P53 Homo sapiens 229-232 9696808-9 1998 Thus, although E4orf6 may play some role, these results suggested that E4orf4 may be the major E4 product responsible for induction of p53-independent apoptosis. e4orf4 71-77 P53 Homo sapiens 135-138 31239671-1 2019 Purpose: The objective of this work was to formulate a delivery system of pDNA encoded p53 gene-loaded chitosan-sodium deoxycholate (CS-DS) nanoparticles, and to evaluate their influence on in vitro cytotoxicity and transfection efficiency of p53 gene. Deoxycholic Acid 112-131 P53 Homo sapiens 87-90 9726816-5 1998 In contrast, PDTC, DDTC, and ammonium dithiocarbamate (ADTC) did not induce apoptosis; rather they led to the induction of p53 and p21 followed by G1/S arrest. prolinedithiocarbamate 13-17 P53 Homo sapiens 123-126 12124477-0 2002 Fluorodeoxyglucose positron emission tomography and somatostatin receptor scintigraphy for diagnosing and staging carcinoid tumours: correlations with the pathological indexes p53 and Ki-67.

Glycogen 35-43 P53 Homo sapiens 77-80 12072912-0 2002 Clinically relevant aminoglycosides can suppress disease-associated premature stop mutations in the IDUA and P53 cDNAs in a mammalian translation system. Aminoglycosides 20-35 P53 Homo sapiens 109-112 12072912-9 2002 Experiments with mammalian cDNAs confirmed these results and demonstrated that these aminoglycosides can also suppress disease-associated premature stop mutations previously identified in the IDUA gene (responsible for the lysosomal storage disease mucopolysaccharidosis I) and the P53 gene (associated with many forms of cancer). Aminoglycosides 85-100 P53 Homo sapiens 282-285 9714336-0 1998 p53-independent induction of WAF1/Cip1 is correlated with osteoblastic differentiation by vitamin D3. Cholecalciferol 90-100 P53 Homo sapiens 0-3 9714336-3 1998 Here we show that in a p53-null human osteoblastic osteosarcoma MG-63 cell line, 10 nM of 1,25(OH)2D3 completely inhibits cell growth and increases alkaline phosphatase activity, which suggests the induction of osteoblastic differentiation. 1,25(oh)2d3 90-101 P53 Homo sapiens 23-26 9714336-6 1998 Our results suggest that the p53-independent WAF1/Cip1 induction by 1,25(OH)2D3 is important for osteoblastic differentiation of MG-63 cells. 1,25(oh)2d3 68-79 P53 Homo sapiens 29-32 31059076-5 2019 RNA-seq analysis revealed that mechanical pressure suppressed glycogen synthesis by activating the p53/phosphatase and tensin homolog pathway, further suppressing glycogen synthase activity. Glycogen 62-70 P53 Homo sapiens 99-102 9649119-10 1998 In agreement with this finding, p53 accumulated rapidly in drug-treated A2780 cells, indicative of a role for titanocene dichloride as a DNA-damaging agent. titanocene dichloride 110-131 P53 Homo sapiens 32-35 31120902-0 2019 The antimalarial drug mefloquine enhances TP53 premature termination codon readthrough by aminoglycoside G418. Aminoglycosides 90-104 P53 Homo sapiens 42-46 11864976-4 2002 The activation of p53 by etoposide resulted in the up-regulation of the pro-apoptotic protein Bax, a result that was prevented by the protein synthesis inhibitor cycloheximide. Cycloheximide 162-175 P53 Homo sapiens 18-21 11980662-6 2002 Inactivation of p53 significantly increased resistance to 5-FU and the antifolates with IC-50(72 h) doses for 5-FU and TDX of >100 and >10 microM, respectively, in the M7TS90-E6 cell line. raltitrexed 119-122 P53 Homo sapiens 16-19 12094375-8 2002 Nuclear p53 immunostaining was detected in 30% of IPN-L as a whole and increased in tandem with the progression of IPN-L (P < 0.01). ipn-l 50-55 P53 Homo sapiens 8-11 9672245-7 1998 Finally, radicicol depletes SKBR3 cells of p185erbB2, Raf-1 and mutant p53, similar to geldanamycin. monorden 9-18 P53 Homo sapiens 71-74 31120902-0 2019 The antimalarial drug mefloquine enhances TP53 premature termination codon readthrough by aminoglycoside G418. antibiotic G 418 105-109 P53 Homo sapiens 42-46 31120902-3 2019 The aminoglycoside G418 can induce TP53 premature termination codon readthrough and thus increase cellular levels of full-length protein. Aminoglycosides 4-18 P53 Homo sapiens 35-39 9535218-3 1998 Treatment of cells with p53 or MnSOD antisense oligonucleotides prior to stimulation with oxLDL, C2-ceramide, TNF-alpha, or H2O2 caused an inhibition of the expression of the respective protein together with a marked reduction of apoptosis. N-acetylsphingosine 97-108 P53 Homo sapiens 24-27 31120902-3 2019 The aminoglycoside G418 can induce TP53 premature termination codon readthrough and thus increase cellular levels of full-length protein. antibiotic G 418 19-23 P53 Homo sapiens 35-39 9535218-4 1998 Exposure to N-acetylcysteine before treatment with oxLDL, C2-ceramide, TNF-alpha, or H2O2 reversed a decrease in cellular glutathione concentrations as well as the enhanced production of p53 and MnSOD mRNA and protein. N-acetylsphingosine 58-69 P53 Homo sapiens 187-190 11884587-0 2002 Stat1-dependent, p53-independent expression of p21(waf1) modulates oxysterol-induced apoptosis. Oxysterols 67-76 P53 Homo sapiens 17-20 31120902-8 2019 Exposure to G418 and mefloquine increased p53 phosphorylation at Ser15 and P21 transcript levels following DNA damage, indicating p53 produced via readthrough was functional. antibiotic G 418 12-16 P53 Homo sapiens 42-45 11948395-10 2002 This was prevented by cycloheximide, suggesting that any stabilizing action of CP-31398 would have to be on newly synthesized p53. Cycloheximide 22-35 P53 Homo sapiens 126-129 31120902-8 2019 Exposure to G418 and mefloquine increased p53 phosphorylation at Ser15 and P21 transcript levels following DNA damage, indicating p53 produced via readthrough was functional. antibiotic G 418 12-16 P53 Homo sapiens 130-133 9773296-8 1998 The most suitable fixatives for immunohistochemical detection of p53 are 70% ethanol and Carnoy solution. carnoy solution 89-104 P53 Homo sapiens 65-68 11791172-5 2002 Many agents also effectively increase cell death when a transcriptionally-defective p53, p53([gln22ser23]), is induced, although a dramatic exception is treatment with 5-FU, which strongly cooperates with wild-type but not p53([gln22ser23]). gln22ser23 94-104 P53 Homo sapiens 84-87 31210846-10 2019 Taken together, decreased ribosome biogenesis in ASMCs resulting in p53-dependent proliferative inhibition, oxidative stress, and apoptosis is one of the underlying mechanisms of AD. asmcs 49-54 P53 Homo sapiens 68-71 11791172-5 2002 Many agents also effectively increase cell death when a transcriptionally-defective p53, p53([gln22ser23]), is induced, although a dramatic exception is treatment with 5-FU, which strongly cooperates with wild-type but not p53([gln22ser23]). gln22ser23 94-104 P53 Homo sapiens 89-92 11791172-5 2002 Many agents also effectively increase cell death when a transcriptionally-defective p53, p53([gln22ser23]), is induced, although a dramatic exception is treatment with 5-FU, which strongly cooperates with wild-type but not p53([gln22ser23]). gln22ser23 94-104 P53 Homo sapiens 89-92 11791172-5 2002 Many agents also effectively increase cell death when a transcriptionally-defective p53, p53([gln22ser23]), is induced, although a dramatic exception is treatment with 5-FU, which strongly cooperates with wild-type but not p53([gln22ser23]). gln22ser23 228-238 P53 Homo sapiens 84-87 9395239-7 1997 Actinomycin D or cycloheximide prevented cell death, suggesting that, in this system, p53-induced apoptosis depends upon macromolecule biosynthesis. Cycloheximide 17-30 P53 Homo sapiens 86-89 9815821-6 1997 This p53-defective cell line was also radiosensitized by CAF, whereas the vector control (AA/PCMV/D), which retained wt p53 activity, was not. Caffeine 57-60 P53 Homo sapiens 5-8 11786354-3 2002 We propose a method for the determination of traces of GST in the p53 C-terminus based on the constant current chronopotentiometric stripping analysis (CPSA) with hanging mercury drop electrode (HMDE). Mercury 171-178 P53 Homo sapiens 66-69 30724469-7 2019 In pancreatic cancer cells, SRPK2 downregulation or overexpression led to modulation of Numb and wild-type p53 protein expression in response to oxaliplatin treatment. Oxaliplatin 145-156 P53 Homo sapiens 107-110 9175647-2 1997 We used human osteosarcoma Saos-LP12 cells, in which wild type (wt) p53 protein was induced by treatment with isopopyl-beta-D-thiogalactopyranoside. isopopyl-beta-d-thiogalactopyranoside 110-147 P53 Homo sapiens 68-71 9175647-5 1997 In addition, we found that frequency of G : C to A : T transition mutations which occurred at the 3" base pair of dipyrimidine sites were significantly lower in the cells with induced wt p53 protein than in the uninduced cells. dipyrimidine 114-126 P53 Homo sapiens 187-190 11719445-2 2001 The p53 tumor suppressor gene is usually mutated in these tumors, and the mutations are "UV signature" single or tandem transitions at dipyrimidine sequences in the DNA-binding domain (DBD). dipyrimidine 135-147 P53 Homo sapiens 4-7 30724469-11 2019 Conversely, SRPK2 silencing decreased cell invasion and migration and increased chemosensitivity; these effects were reversed by silencing p53 in oxaliplatin-treated pancreatic cancer cells. Oxaliplatin 146-157 P53 Homo sapiens 139-142 30987009-5 2019 Intriguingly, 25 muM luteolin reduced cell viability through apoptotic induction, which was intensified in p53-expressing cells while 1 muM oxaliplatin caused cell cycle arrest at G0/G1-phase via the p53/p21-dependent mechanism. Oxaliplatin 140-151 P53 Homo sapiens 200-203 11585742-3 2001 p53 codons containing methylated CpG sequences are preferential targets for formation of adducts by (+/-) anti-7beta,8alpha-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE). 7beta 111-116 P53 Homo sapiens 0-3 11684014-4 2001 Inhibition of endogenous ASPP function suppresses the apoptotic function of endogenous p53 in response to apoptotic stimuli. aspp 25-29 P53 Homo sapiens 87-90 11684014-5 2001 ASPP enhance the DNA binding and transactivation function of p53 on the promoters of proapoptotic genes in vivo. aspp 0-4 P53 Homo sapiens 61-64 11684014-6 2001 Two tumor-derived p53 mutants with reduced apoptotic function were defective in cooperating with ASPP in apoptosis induction. aspp 97-101 P53 Homo sapiens 18-21 11684014-7 2001 The expression of ASPP is frequently downregulated in human breast carcinomas expressing wild-type p53 but not mutant p53. aspp 18-22 P53 Homo sapiens 99-102 11684014-8 2001 Therefore, ASPP regulate the tumor suppression function of p53 in vivo. aspp 11-15 P53 Homo sapiens 59-62 11390388-1 2001 Electrophilic eicosanoids of the J series, with their distinctive cross-conjugated alpha,beta-unsaturated ketone, inactivate genetically wild type tumor suppressor p53 in a manner analogous to prostaglandins of the A series. alpha,beta-unsaturated ketone 83-112 P53 Homo sapiens 164-167 11477204-8 2001 Furthermore, thromboxane A(2) enhanced trophoblast apoptosis, determined using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining, cell morphology, and a concentration-dependent increase in p53 expression. thromboxane a 13-26 P53 Homo sapiens 218-221 11406660-8 2001 p53 mutations were detected in AFX (4/6; 67%) and S-MFH (1/4; 25%), but not in BFH (0/5; 0%) using polymerase chain reaction-single-strand conformation polymorphism, and all of the mutations in AFX were either C-T transitions or at dipyrimidine sites. dipyrimidine 232-244 P53 Homo sapiens 0-3 11313183-10 2001 Our data indicate that BBR3464 may be a promising agent in the treatment of tumours unresponsive to cisplatin and with a non-functional p53. BBR 3464 23-30 P53 Homo sapiens 136-139 11181455-0 2001 Resveratrol analog, 3,4,5,4"-tetrahydroxystilbene, differentially induces pro-apoptotic p53/Bax gene expression and inhibits the growth of transformed cells but not their normal counterparts. 3,4,5,4'-tetrahydroxystilbene 20-49 P53 Homo sapiens 88-91 11159753-0 2001 Role of TP53 in repair of N-(deoxyguanosin-8-yl)-4-aminobiphenyl adducts in human transitional cell carcinoma of the urinary bladder. N-(deoxyguanosin-8-yl)-4-aminobiphenyl 26-64 P53 Homo sapiens 8-12 11106264-11 2000 Therefore, in colon carcinomas that express wtp53, the approach to sensitize tumors to Fas-mediated apoptosis may be further enhanced from the effect of FUra-LV in elevating Fas expression in a p53-dependent manner. fura-lv 153-160 P53 Homo sapiens 46-49 11033415-1 2000 The antiproliferative effect of Tempol, a stable nitroxide free radical, was investigated on the p53-negative human leukemia cell line HL60. tempol 32-38 P53 Homo sapiens 97-100 10969787-7 2000 Moreover, AdRSVpHyde induced apoptosis and stimulated p53 expression. adrsvphyde 10-20 P53 Homo sapiens 54-57 10867037-5 2000 p53 mRNA abundance was 187% higher in ZD Opti-MEM cells and >100% higher in ZD Chelex cells compared with their respective controls. opti-mem 41-49 P53 Homo sapiens 0-3 10842192-1 2000 We have previously shown that bladder urothelium of people living in the cesium-137 ((137)Cs)-contaminated areas of Ukraine demonstrates accumulation of stable p53 and p53 mutational inactivation, preferentially through G:C to A:T transition mutations at CpG dinucleotides, with a codon 245 hot spot. Cesium-137 73-83 P53 Homo sapiens 160-163 10842192-1 2000 We have previously shown that bladder urothelium of people living in the cesium-137 ((137)Cs)-contaminated areas of Ukraine demonstrates accumulation of stable p53 and p53 mutational inactivation, preferentially through G:C to A:T transition mutations at CpG dinucleotides, with a codon 245 hot spot. Cesium-137 73-83 P53 Homo sapiens 168-171 10785598-0 2000 Molecular downstream events and induction of thymidylate synthase in mutant and wild-type p53 colon cancer cell lines after treatment with 5-fluorouracil and the thymidylate synthase inhibitor raltitrexed. raltitrexed 193-204 P53 Homo sapiens 90-93 10785598-6 2000 TS induction was highest after ZD1694 exposure in the mt p53 cells HT29 and WiDr/F (6-10-fold). raltitrexed 31-37 P53 Homo sapiens 57-60 10777712-5 2000 Pretreatment of fATII cells with l-buthionine-(S,R)-sulfoximine, an irreversible inhibitor of gamma-glutamylcysteine synthetase, the rate-limiting enzyme in the biosynthesis of glutathione (GSH), enhanced Bax and p53 expression over Bcl-2. l-buthionine sulfoximine 33-63 P53 Homo sapiens 213-216 10811471-4 2000 Ad-p53 and DNA-damaging agents (cis-diamminedichloroplatinum(II), etoposide, and 7-ethyl-10-hydrocycamptothecin) showed synergistic effects in six of seven cell lines but additive effects against a p53-mutated cell line. 7-ethyl-10-hydrocycamptothecin 81-111 P53 Homo sapiens 3-6 10811471-4 2000 Ad-p53 and DNA-damaging agents (cis-diamminedichloroplatinum(II), etoposide, and 7-ethyl-10-hydrocycamptothecin) showed synergistic effects in six of seven cell lines but additive effects against a p53-mutated cell line. 7-ethyl-10-hydrocycamptothecin 81-111 P53 Homo sapiens 198-201 10676641-9 2000 These findings suggest that nt -450 may constitute a critical site for initiation of de novo methylation and processive spreading of methylation associated with transcriptional inactivation of the p53 gene. nt -450 28-35 P53 Homo sapiens 197-200 10631110-0 2000 Nitric oxide nitrates tyrosine residues of tumor-suppressor p53 protein in MCF-7 cells. Nitrates 13-21 P53 Homo sapiens 60-63 10631110-2 2000 As nitration of tyrosine residues in various proteins has been shown to inhibit their functions, we examined whether NO nitrates tyrosine residues in p53 protein. Nitrates 120-128 P53 Homo sapiens 150-153 10769661-1 2000 The present study was performed to investigate whether the introduction of a wild-type p53 gene into human osteosarcoma cells could alter the growth rate and enhance the cytocidal effect of cisplatin (CDDP) and the synergistic antitumor effect of caffeine. Caffeine 247-255 P53 Homo sapiens 87-90 10769661-5 2000 Caffeine significantly potentiated the cytocidal effect of CDDP in the Saos2/p53 cells. Caffeine 0-8 P53 Homo sapiens 77-80 10769661-6 2000 Furthermore, the TUNEL assay revealed that following treatment both with CDDP alone and with CDDP combined with caffeine, a higher percentage of the Saos2/p53 cells underwent apoptosis than did the parental Saos2 cells. Caffeine 112-120 P53 Homo sapiens 155-158 10769661-7 2000 Therefore the cytocidal effect of CDDP and the synergistic antitumor effect of caffeine are enhanced by the introduction of a wild-type p53 gene into a human osteosarcoma cell line null for p53. Caffeine 79-87 P53 Homo sapiens 136-139 10772337-5 2000 The altered gene expression of c-myc and p53 suggested that a novel apoptosis pathway, other than that suppressed by IL-6, might be triggered by a complex of DM650 and IL-6. dm650 158-163 P53 Homo sapiens 41-44 10536167-4 1999 The initial transient cell arrest at the G1 checkpoint seen at 8-16 h of treatment with 0.15 microM CPT was accompanied by the rapid accumulation of p53 (preventable by cycloheximide) in the nucleus; the rise (>20-fold) in p53 was maximal for S phase cells. Cycloheximide 169-182 P53 Homo sapiens 149-152 10545796-3 1999 In this study, we demonstrate that the tumor suppressor protein p53 is stabilized in response to DNA damage by 5-MeCDE but fails to induce the cells" protective mechanism of G1 arrest in the human breast carcinoma cell line, MCF-7. 1,2-dihydroxy-epoxy-1,2,3,4-tetrahydro-5-methylchrysene 111-118 P53 Homo sapiens 64-67 10545796-5 1999 Western analyses revealed that, though both actinomycin D and 5-MeCDE treatment stabilized p53, only trace levels of p21(waf1/cip1) were seen in the latter case. 1,2-dihydroxy-epoxy-1,2,3,4-tetrahydro-5-methylchrysene 62-69 P53 Homo sapiens 91-94 10545796-6 1999 This lack of p21(waf1/cip1) expression in 5-MeCDE-treated cells is attributed to a stealth characteristic of this environmental carcinogen that allows it to damage DNA and still escape the p53-mediated cellular defense mechanism of G1 arrest. 1,2-dihydroxy-epoxy-1,2,3,4-tetrahydro-5-methylchrysene 42-49 P53 Homo sapiens 189-192 10628368-6 1999 The status of the p53 gene of tumor cells thereby may influence the efficacy of the HSV-TK/GCV system. Ganciclovir 91-94 P53 Homo sapiens 18-21 10411938-2 1999 Here we show that TK/GCV treatment induces p53 accumulation and increases cell surface expression of CD95 and tumor necrosis factor receptor, which is likely to involve p53-mediated translocation of CD95 to the cell surface. Ganciclovir 21-24 P53 Homo sapiens 43-46 10411938-2 1999 Here we show that TK/GCV treatment induces p53 accumulation and increases cell surface expression of CD95 and tumor necrosis factor receptor, which is likely to involve p53-mediated translocation of CD95 to the cell surface. Ganciclovir 21-24 P53 Homo sapiens 169-172 10380883-8 1999 We also show that relatively low concentrations of dithiothreitol but not of 2-mercaptoethanol decrease the concentration of free zinc ions, thereby preventing their inhibitory effect on binding of p53 to DNA. Dithiothreitol 51-65 P53 Homo sapiens 198-201 9106619-7 1997 It was also shown that vanadate blocked differentiation of IW32 cells induced by sodium butyrate, VM-26, and p53. Vanadates 23-31 P53 Homo sapiens 109-112 9066726-1 1997 It has been found by PCR-SSCP analysis and direct DNA sequencing that a human salivary adenosquamous carcinoma-forming cell line, TYS, has a mutant p53 gene at codon 281Asp-->His. TYS 130-133 P53 Homo sapiens 148-151 9118908-0 1996 Carcinogenic potential of benzene and toluene when evaluated using cyclin-dependent kinase activation and p53-DNA binding. Toluene 38-45 P53 Homo sapiens 106-109 9118908-4 1996 Kinase activation and subsequent hyperphosphorylation of pRb105 and p53 by benzene or toluene may be responsible for their growth promotional effects, but it does not account for increased potential of benzene to induce cancer. Toluene 86-93 P53 Homo sapiens 68-71 8946936-4 1996 However, a cell-cycle arrest in G0/G1 phase was observed in Raji cells after the treatment with C2-ceramide, which was accompanied by the dephosphorylation of retinoblastoma (RB) gene products and decreased expression of p53 proteins. N-acetylsphingosine 96-107 P53 Homo sapiens 221-224 8840989-2 1996 With a single exposure at a concentration of 1 microM for 2 h, ZD1694 completely inhibits thymidylate synthase over 72 h and causes a sustained growth for at least 120 h, DNA damage, and p53 induction in human carcinoma cells. raltitrexed 63-69 P53 Homo sapiens 187-190 8870682-8 1996 Expression of the inducible NO synthase in response to lipopolysaccharide and interferon-gamma caused apoptosis in RAW 264.7 macrophages and neomycin-vector controls within 24 h. In contrast, p53 antisense RNA-expressing clones appeared highly resistant towards endogenous NO, although inducible NO synthase induction with concomitant nitrite production remained unchanged. Nitrites 335-342 P53 Homo sapiens 192-195 8837615-0 1996 Selective radiosensitization of p53-deficient cells by caffeine-mediated activation of p34cdc2 kinase. Caffeine 55-63 P53 Homo sapiens 32-35 8837615-6 1996 We demonstrate that abrogation of G2 arrest by caffeine-mediated activation of p34cdc2 kinase results in the selective sensitization of p53-deficient primary and tumor cells to irradiation-induced apoptosis. Caffeine 47-55 P53 Homo sapiens 136-139 8831577-11 1996 Treatment with DX or AMSA caused similar effects, suggesting that p53-induced changes in cyclin, cdk, and cdk inhibitors after DNA damage are not responsible for the marked reduction in the cytotoxicity of DX we observed in wt p53-expressing cells. Amsacrine 21-25 P53 Homo sapiens 66-69 8603415-5 1996 Cycloheximide treatment of the cells showed that the low level of p53 mRNA in non-BL lymphoid cells can not be attributed to posttranscriptional regulation by a labile protein. Cycloheximide 0-13 P53 Homo sapiens 66-69 8570169-7 1995 In addition, cycloheximide and actinomycin D inhibited wt p53-induced apoptosis. Cycloheximide 13-26 P53 Homo sapiens 58-61 7478511-2 1995 Exogenous wild-type p53 transcripts were detected at various expression levels in 8 of 117 G418-resistant clones. antibiotic G 418 91-95 P53 Homo sapiens 20-23 7591958-0 1995 Inhibition of p53 protein phosphorylation by 9-hydroxyellipticine: a possible anticancer mechanism. 9-hydroxyellipticine 45-65 P53 Homo sapiens 14-17 7591958-2 1995 We found that ellipticine and 9-hydroxyellipticine (9HE), antitumor alkaloids, caused selective inhibition of p53 protein phosphorylation in Lewis lung carcinoma and SW480 (human colon cancer cell line) in a concentration-dependent manner from 0.1 to 100 microM. 9-hydroxyellipticine 30-50 P53 Homo sapiens 110-113 7591958-2 1995 We found that ellipticine and 9-hydroxyellipticine (9HE), antitumor alkaloids, caused selective inhibition of p53 protein phosphorylation in Lewis lung carcinoma and SW480 (human colon cancer cell line) in a concentration-dependent manner from 0.1 to 100 microM. 9-hydroxyellipticine 52-55 P53 Homo sapiens 110-113 7656242-2 1995 Two "hot regions" at codons 223-250 and 257-283 of the p53 gene were easily attacked by nitroso-2-acetylaminofluorene or acetoxy-2-acetylaminofluorene. nitroso-2-acetylaminofluorene 88-117 P53 Homo sapiens 55-58 7753562-3 1995 Here we report the effect of calcium phosphate-mediated transfection, a technique commonly used in studies of transient gene expression in mammalian cells, on fibroblasts containing wild-type p53. calcium phosphate 29-46 P53 Homo sapiens 192-195 7897229-10 1995 Third, p53-56lyn was probably activated after cell stimulation with zymosan, because the phosphorylation levels of a synthetic copolymer of glutamine-tyrosine were increased in Triton X-100-insoluble fraction. Zymosan 68-75 P53 Homo sapiens 7-10 7897229-14 1995 Because zymosan interacts with human monocytes via beta 2 integrins, which are known to be cytoskeleton-associated, we suggest that p53-56lyn provides the molecular link between zymosan receptors and cytoskeleton, and directs the cytoskeletal reorganization in the periphagosomal area. Zymosan 8-15 P53 Homo sapiens 132-135 7705936-1 1995 We introduced the mutant p53 gene (codon 273Arg-His) into human fibroblasts (SUSM-I cells) previously immortalized with 4-nitroquinoline I-oxide (4NQO) and obtained 2 clonal cell lines (SUSM-i/p53-1 and SUSM-1/p53-6) expressing the mutant p53. 4-Nitroquinoline 120-136 P53 Homo sapiens 25-28 7883998-4 1995 Induced differentiation of the p53-deficient promyelocytic HL-60 cells along the monocytic lineage by phorbol ester or 1a,25 dihydroxyvitamin D3 resulted in a marked increase of both p21WAF1/CIP1/SDI1 mRNA and protein expression due to enhanced mRNA stability. Calcitriol 119-144 P53 Homo sapiens 31-34 7854771-6 1995 The expression of p53 was reduced to 60% for the first 4 h after the addition of cycloheximide, and showed no significant changes at least for 20 h. Treatment with Triton X-100 increased p53 immunoreactivity throughout the cell cycle. Cycloheximide 81-94 P53 Homo sapiens 18-21 7845676-2 1995 Freshly isolated PBMCs, which are in the Go phase of the cell cycle, were shown to express low levels of p53 mRNA that was rapidly degraded with a half life of 1 h. The rapid decay of p53 mRNA in quiescent PBMCs was dependent on global protein synthesis as treatment with cycloheximide resulted in stabilization of the p53 message. Cycloheximide 272-285 P53 Homo sapiens 105-108 7834638-4 1995 We show that p53-independent induction of WAF1/CIP1 occurs in human leukemia cells treated with 12-O-tetradecanoylphorbol-13-acetate, okadaic acid, or IFN-gamma but not with retinoic acid, vitamin D3, or DMSO. Cholecalciferol 189-199 P53 Homo sapiens 13-16 7860045-1 1995 Several studies of benign breast lesions using methacran-fixed, paraffin-embedded tissues and cytological preparations have suggested that p53 accumulation in these lesions as detected by immunohistochemical (IHC) staining is rare to absent. methacran 47-56 P53 Homo sapiens 139-142 7527943-5 1994 Altogether, microwave boiling of the tissue sections in citrate buffer clearly improved the immunoreactivity for cytokeratin 18, oestrogen receptor, Ki-67 protein, PCNA, p53 protein, retinoblastoma gene protein and c-erbB-2 protein. Citric Acid 56-63 P53 Homo sapiens 170-173 8033087-4 1994 The frequency of tumors with mutations in p53, often multiple, accompanied by the appearance of multiple altered-length alleles suggest that DNA replication or repair defects may presage genomic instability in cases with FHBC. fhbc 221-225 P53 Homo sapiens 42-45 7926727-6 1994 In addition, hydrophobic residues Leu-14 and Phe-19 are crucial for the interactions between p53 and human mdm-2 (hdm-2). Phenylalanine 45-48 P53 Homo sapiens 93-96 7510864-6 1994 It was found that addition of sodium vanadate to the lysis buffer converted part of p53 molecules into a mutant conformation that is recognized by the PAb 240 monoclonal antibodies. Vanadates 30-45 P53 Homo sapiens 84-87 7510864-7 1994 The effect of vanadate on p53 conformation was prominent even if it was added to the cell lysates after 15 min of pre-incubation at 37 degrees C. This further excluded its possible role as phosphatase inhibitor in the system and suggested a direct interaction with the p53 protein itself. Vanadates 14-22 P53 Homo sapiens 26-29 7510864-7 1994 The effect of vanadate on p53 conformation was prominent even if it was added to the cell lysates after 15 min of pre-incubation at 37 degrees C. This further excluded its possible role as phosphatase inhibitor in the system and suggested a direct interaction with the p53 protein itself. Vanadates 14-22 P53 Homo sapiens 269-272 7510864-8 1994 Based on these data we recommend to avoid using sodium vanadate as a phosphatase inhibitor in experiments where in vivo conformational changes of wild type p53 are studied. Vanadates 48-63 P53 Homo sapiens 156-159 8278402-4 1994 Mutant p53 fusion proteins carrying amino acid substitutions Glu-213, Ile-237, or Tyr-238, derived from mutant p53 genes of Burkitt lymphomas, failed to catalyze these reactions. Isoleucine 70-73 P53 Homo sapiens 7-10 7807177-5 1994 Of several G418-resistant clones obtained from each transfection, a few expressed the s-Myc or wt-p53 proteins. antibiotic G 418 11-15 P53 Homo sapiens 98-101 8496597-0 1993 Differential action of cycloheximide and activation stimuli on transcription of tumor necrosis factor-alpha, IL-1 beta, IL-8, and P53 genes in human monocytes.

Einsteinium 24-28 P53 Homo sapiens 102-105 10331854-4 1999 RESULTS: Both BL-13 and BL-28 cells (each expressing p53 with a wild-type sequence) fail to arrest at the G2 checkpoint after radiation, but nevertheless caffeine did induce radiosensitization. Caffeine 154-162 P53 Homo sapiens 53-56 10331854-5 1999 In contrast, in BL-17/2 cells (expressing p53 with a point mutation in codon 280), caffeine treatment abrogated the radiation-induced G2 arrest but was not accompanied by radiosensitization.

Overall, these findings provide the first indication of the cell cycle regulatory pathways by which polyamine antagonists such as analogues might inhibit growth in cells containing wild-type p53 and further suggest a mechanistic basis for differential cellular responses to these agents. Polyamines 173-182 P53 Homo sapiens 264-267 10082308-3 1999 METHODS: We report here a parallel flow cytometric method for semiquantitative detection of p53 protein and apoptosis (percent of apoptotic cells) in a pre-B leukemic cell line (NALM-6) exposed to various antitumor agents (2.35 microg/ml etoposide; 0.175 microg/ml FCE296; 0.4 microg/ml FCE624; and 1.5 microg/ml L-PAM). fce624 287-293 P53 Homo sapiens 92-95 10030268-2 1999 This study tests the hypothesis that the response of cell lines derived from GM to fractionated radiotherapy depends on the function of wild-type p53 (wt p53), a tumor suppressor gene frequently mutated in GM tumors. gm 77-79 P53 Homo sapiens 146-149 1280773-4 1992 Sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis demonstrated unequivocal heterogeneity of migration rate in p53 bands. polyacrylamide 23-37 P53 Homo sapiens 127-130 21584507-1 1992 The nuclear phosphoprotein p53, named according to its apparent molecular weight on SDS-polyacrylamide gels is expressed, albeit at low levels, in a variety of cell types. polyacrylamide 88-102 P53 Homo sapiens 27-30 10030268-2 1999 This study tests the hypothesis that the response of cell lines derived from GM to fractionated radiotherapy depends on the function of wild-type p53 (wt p53), a tumor suppressor gene frequently mutated in GM tumors. gm 77-79 P53 Homo sapiens 154-157 30987009-6 2019 Moreover, luteolin treatment was found to reduce oxaliplatin-treated p53-null cell viability and colony counts further, thereby demonstrating an additional effect of luteolin in the killing of human colorectal tumor HCT116 cells not expressing functional p53 protein. Oxaliplatin 49-60 P53 Homo sapiens 69-72 10030268-11 1999 CONCLUSIONS: The effect of fractionated radiotherapy in GM may depend on the function of the tumor suppressor gene p53. gm 56-58 P53 Homo sapiens 115-118 1737852-7 1992 The other two nonhereditary p53 mutations included a T to G transversion at codon 270 (phenylalanine to cysteine) and a G to C transversion at codon 248 (arginine to proline). Phenylalanine 87-100 P53 Homo sapiens 28-31 30987009-7 2019 The findings suggest that luteolin can induce p53-mediated apoptosis regardless of oxaliplatin treatment and may eliminate oxaliplatin-resistant p53-null colorectal cells.

Caffeine 215-223 P53 Homo sapiens 150-153 10049063-0 1999 DNA damage-associated cell cycle and cell death control is differentially modulated by caffeine in clones with p53 mutations. Caffeine 87-95 P53 Homo sapiens 111-114 10049063-1 1999 Caffeine is known to potentiate the cytotoxic effects of DNA damaging agents and increases the sensitivity of p53-deficient cells to X-irradiation (X-IR). Caffeine 0-8 P53 Homo sapiens 110-113 10049063-7 1999 These results suggest that the cytocidal effect of caffeine may need to be verified independently of its cell cycle regulatory activities at least in some cases with p53 mutation.

Caffeine 34-42 P53 Homo sapiens 155-158 8968086-6 1996 The differential sensitivity of p53(-/-) cells to X-rays and caffeine was thought to be due to override of the G2-M block to cell cycle progression. Caffeine 61-69 P53 Homo sapiens 32-35 8968086-9 1996 However, for p53(-/-) cells, a greater proportion were in S phase after treatment with caffeine, and a complete loss of S-phase delay was observed after UV irradiation. Caffeine 87-95 P53 Homo sapiens 13-16 35429966-5 2022 In addition, we observed that Triptolide and Nutlin-3a were also cooperative in part of p53 deficient cases. triptolide 30-40 P53 Homo sapiens 88-91 35429966-6 2022 Mechanistically, Nutlin-3a upregulated the transcriptional expressions of the p53 downstream targets PUMA and p21, while Triptolide declined the mRNA levels of two anti-apoptotic factors, XIAP and Mcl-1, in p53 wt cells. triptolide 121-131 P53 Homo sapiens 78-81 35429966-6 2022 Mechanistically, Nutlin-3a upregulated the transcriptional expressions of the p53 downstream targets PUMA and p21, while Triptolide declined the mRNA levels of two anti-apoptotic factors, XIAP and Mcl-1, in p53 wt cells. triptolide 121-131 P53 Homo sapiens 207-210 35429966-8 2022 Our results revealed that Triptolide monotherapy exerted its antileukemia effect via both p53-dependent and independent ways, with the latter through perturbation of the MYC-ATF4 axis-mediated ER stress. triptolide 26-36 P53 Homo sapiens 90-93 8968086-11 1996 Greater sensitization of p53(-/-) cells to caffeine could be mediated via override of S-phase delay.

Lovastatin 18-28 P53 Homo sapiens 113-116 8018565-9 1994 The protein synthesis inhibitor cycloheximide completely abolished the PMA-induced down-modulation of the p53 mRNA, suggesting that a short-lived protein was involved in the down-modulation. Cycloheximide 32-45 P53 Homo sapiens 106-109 8106638-13 1994 As p53 protein is a regulator of guanine nucleotide synthesis, the loss of normal inhibitory regulation by the p53 mutation would serve to increase the availability of GTP for the transduction of signals essential for increased cell growth and hormone expression in the adrenal tumors. Guanine Nucleotides 33-51 P53 Homo sapiens 3-6 8106638-13 1994 As p53 protein is a regulator of guanine nucleotide synthesis, the loss of normal inhibitory regulation by the p53 mutation would serve to increase the availability of GTP for the transduction of signals essential for increased cell growth and hormone expression in the adrenal tumors. Guanine Nucleotides 33-51 P53 Homo sapiens 111-114 30128010-7 2018 These results suggested that triptolide induces protective autophagy, suppresses cell viability and promotes apoptosis in human cervical cancer cells by inducing the autophagy-targeting phosphoinositide 3-kinase/Akt/mTOR, p38, MAPK, p53 and Foxo3a pathways. triptolide 29-39 P53 Homo sapiens 233-236 30197757-8 2018 Cross-talk between Zac1, IL-11, p53, and suppressor of cytokine signaling 3 was differentially affected by copper sulfate, digoxin, and caffeine.

Polysaccharides 125-139 P53 Homo sapiens 64-67 27238606-1 2016 BACKGROUND: MK-8242 is an inhibitor of MDM2 that stabilizes the tumor suppressor TP53 and induces growth arrest or apoptosis downstream of TP53 induction. mk-8242 12-19 P53 Homo sapiens 81-85 27238606-1 2016 BACKGROUND: MK-8242 is an inhibitor of MDM2 that stabilizes the tumor suppressor TP53 and induces growth arrest or apoptosis downstream of TP53 induction. mk-8242 12-19 P53 Homo sapiens 139-143 27238606-3 2016 RESULTS: The median IC50 for MK-8242 was 0.07 muM for TP53 wild-type cell lines versus >10 muM for TP53 mutant cell lines. mk-8242 29-36 P53 Homo sapiens 54-58 27238606-4 2016 MK-8242 induced a twofold or greater delay in time to event in 10 of 17 (59%) of TP53 wild-type solid tumor xenografts, excluding osteosarcoma xenografts that have very low TP53 expression. mk-8242 0-7 P53 Homo sapiens 81-85 27238606-4 2016 MK-8242 induced a twofold or greater delay in time to event in 10 of 17 (59%) of TP53 wild-type solid tumor xenografts, excluding osteosarcoma xenografts that have very low TP53 expression. mk-8242 0-7 P53 Homo sapiens 173-177 27238606-8 2016 The expected pharmacodynamic responses to TP53 activation were observed in TP53 wild-type models treated with MK-8242. mk-8242 110-117 P53 Homo sapiens 42-46 27238606-8 2016 The expected pharmacodynamic responses to TP53 activation were observed in TP53 wild-type models treated with MK-8242. mk-8242 110-117 P53 Homo sapiens 75-79 27609465-0 2016 Upregulation of CYP2S1 by oxaliplatin is associated with p53 status in colorectal cancer cell lines. Oxaliplatin 26-37 P53 Homo sapiens 57-60 27609465-3 2016 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin 22-33 P53 Homo sapiens 111-114 27609465-3 2016 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin 22-33 P53 Homo sapiens 169-172 27609465-3 2016 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin 22-33 P53 Homo sapiens 169-172 27609465-4 2016 Administration of oxaliplatin significantly induced p53 accumulation and enhanced expression of CYP2S1 in HCT116 cells with wild-type p53.

Oxaliplatin 122-133 P53 Homo sapiens 222-225 27609465-8 2016 These results suggest that oxaliplatin exerts its inhibitory effects in human CRC cells via upregulation of CYP2S1 expression in a p53-dependent manner. Oxaliplatin 27-38 P53 Homo sapiens 131-134 25268149-9 2016 The level of the tumor suppressor protein p53 in HeLa cells increased significantly upon treatment with free epirubicin, but remained relatively unchanged when cells were treated with equivalent dose of nanoparticle-loaded drug, suggesting a possible shift from p53-dependent DNA/RNA intercalation-based induction of cytotoxicity by free epirubicin to a caspase 3-induced cell death by the epirubicin-loaded PBCA formulation. Enbucrilate 408-412 P53 Homo sapiens 42-45 27288242-11 2016 Besides, sunitinib boosted cortical and hippocampal p53 and executioner caspase-3 and decreased nuclear factor kappa B and Bcl-2 levels promoting apoptotic cell death.

Ganciclovir 53-56 P53 Homo sapiens 10-13 26934443-2 2016 We hypothesize that the efficacy of HSV-TK/GCV therapy is at least partially dependent on p53 status in hepatocellular carcinoma (HCC) patients. Ganciclovir 43-46 P53 Homo sapiens 90-93 26934443-6 2016 Similarly, ASPP2 reduced survival in rAdV-TK/GCV-treated primary HCC cells expressing p53 wild-type but not a p53 R249S mutant. Ganciclovir 45-48 P53 Homo sapiens 86-89 26934443-7 2016 Mutated p53 was unable to bind to ASPP2, suggesting that the increase in rAdV-TK/GCV-induced cell death resulting from ASPP2 overexpression was dependent on its interaction with p53. Ganciclovir 81-84 P53 Homo sapiens 8-11 26934443-7 2016 Mutated p53 was unable to bind to ASPP2, suggesting that the increase in rAdV-TK/GCV-induced cell death resulting from ASPP2 overexpression was dependent on its interaction with p53.

Caffeine 12-20 P53 Homo sapiens 124-127 26456774-6 2015 DHT inhibited resveratrol-stimulated phosphorylation of Ser-15 of p53 in a concentration-dependent manner. Dihydrotestosterone 0-3 P53 Homo sapiens 66-69 26456774-8 2015 DHT inhibited resveratrol-induced nuclear complex of p53-COX-2 formation which is required p53-dependent apoptosis. Dihydrotestosterone 0-3 P53 Homo sapiens 53-56 26456774-8 2015 DHT inhibited resveratrol-induced nuclear complex of p53-COX-2 formation which is required p53-dependent apoptosis.

Dihydrotestosterone 95-98 P53 Homo sapiens 22-25 26456774-9 2015 ChIP studies of COX-2/p53 binding to DNA and expression of p53-responsive genes indicated that DHT inhibited resveratrol-induced p53-directed transcriptional activity. Dihydrotestosterone 95-98 P53 Homo sapiens 59-62 26456774-9 2015 ChIP studies of COX-2/p53 binding to DNA and expression of p53-responsive genes indicated that DHT inhibited resveratrol-induced p53-directed transcriptional activity. Dihydrotestosterone 95-98 P53 Homo sapiens 59-62 26456774-10 2015 In addition, DHT did inhibit resveratrol-induced COX-2/p53-dependent gene expression. Dihydrotestosterone 13-16 P53 Homo sapiens 55-58 26456774-11 2015 These results suggest that DHT inhibits p53-dependent apoptosis in breast cancer cells by interfering with nuclear COX-2 accumulation which is essential for stimulation of apoptotic pathways. Dihydrotestosterone 27-30 P53 Homo sapiens 40-43 25944179-1 2015 ZMC1 {azetidinecarbothioic acid, [1-(2-pyridinyl) ethylidene] hydrazide} is a lead compound being developed as one of the first mutant p53 targeted anti-cancer drugs. azetidinecarbothioic acid 6-31 P53 Homo sapiens 135-138 26386653-7 2015 We also found that under serum deprivation condition, leptin decreases p53 levels and the inhibitory leptin effect is lost when cells were pretreated with 50 muM PD98059 or 10 muM LY29004; or were transfected with dominant negative mutants of intermediates of these pathways, suggesting that MAPK and PI3K signaling pathways are necessaries for leptin action. ly29004 180-187 P53 Homo sapiens 71-74 25716429-4 2015 Among them, compound 4 (quercetagetin 3,4"-dimethyl ether) showed inhibitory activity against cellular senescence, which was confirmed by senescence-associated beta-galactosidase (SA-beta-gal) activity, p53 and p21 protein levels, and intracellular ROS levels. quercetagetin 3,4'-dimethyl ether 24-57 P53 Homo sapiens 203-206 26208523-0 2015 The 1,2-Diaminocyclohexane Carrier Ligand in Oxaliplatin Induces p53-Dependent Transcriptional Repression of Factors Involved in Thymidylate Biosynthesis. Oxaliplatin 45-56 P53 Homo sapiens 65-68 26208523-3 2015 In the p53-proficient colorectal cancer cell line HCT116, oxaliplatin represses the expression of deoxyuridine triphosphatase (dUTPase), a ubiquitous pyrophosphatase that catalyzes the hydrolysis of dUTP to dUMP and inhibits dUTP-mediated cytotoxicity. Oxaliplatin 58-69 P53 Homo sapiens 7-10 26091798-7 2015 The results show that short-term exposure of BEAS-2B cells to arsenic or Cr(VI) was able to activate both p53 and p21. chromium hexavalent ion 73-79 P53 Homo sapiens 106-109 26225749-5 2015 Treatment of MCF-7 cells with metformin or phenformin induced increase in p53 protein levels and the transcription of its downstream target genes, Bax and p21, in a dose-dependent manner. Phenformin 43-53 P53 Homo sapiens 74-77 26225749-7 2015 The present study showed that p53 is required for metformin or phenformin-induced growth inhibition, senescence and apoptosis in breast cancer cells. Phenformin 63-73 P53 Homo sapiens 30-33 26194899-4 2015 In further experiments, p53 protein expression was increased, and H2AX phosphorylation and p21 protein expression were induced after treatment with 3EZ, 20Ac-ingenol. 20ac-ingenol 153-165 P53 Homo sapiens 24-27 25407396-9 2015 The comparison of the different ligands demonstrates that stictic acid has a great potential as a p53 activator in terms of less adverse effects although it has poorer pharmacokinetic properties. stictic acid 58-70 P53 Homo sapiens 98-101 25917567-0 2015 FLLL12 induces apoptosis in lung cancer cells through a p53/p73-independent but death receptor 5-dependent pathway. flll12 0-6 P53 Homo sapiens 56-59 26086967-4 2015 APR-246 is a prodrug that is converted to the active compound methylene quinuclidinone (MQ), a Michael acceptor that binds to cysteine residues in mutant p53 and restores its wild-type conformation. SCHEMBL4738034 62-86 P53 Homo sapiens 154-157 25651236-0 2015 Apoptosis of Bel-7402 human hepatoma cells induced by a ruthenium(II) complex coordinated by cordycepin through the p53 pathway. Ruthenium(II) 56-69 P53 Homo sapiens 116-119 25981919-13 2015 CONCLUSION: The current findings strongly indicate that both CTS and DTS could inhibit the growth of apoptosis-resistant colon cancer cells through induction of autophagic cell death and p53-independent cytotoxicity. dibenzyl trisulfide 69-72 P53 Homo sapiens 187-190 26222594-2 2015 The obtained xPolyR8-KLA(TPP) could not only initiate tumor cell apoptosis by C-KLA(TPP) with improved cell penetrating ability, but was also capable of loading and delivering the tumor cell suppressing p53 gene. xpolyr8-kla 13-24 P53 Homo sapiens 203-206 26222594-4 2015 By regulating both the intrinsic and extrinsic apoptotic pathways, the xPolyR8-KLA(TPP)/p53 complex performed as a synergetic system and lead to a more efficient cancer cell death. xpolyr8-kla 71-82 P53 Homo sapiens 88-91 25875797-0 2015 Primary and liver metastasis-derived cell lines from KrasG12D; Trp53R172H; Pdx-1 Cre animals undergo apoptosis in response to triptolide. triptolide 126-136 P53 Homo sapiens 63-68 25914461-8 2015 Alternol activated caspase 3, upregulated p53 and p21 expression, and downregulated Bcl-2 expression in a dose-dependent manner. Alternol 0-8 P53 Homo sapiens 42-45 25534115-0 2015 ASPP2 enhances oxaliplatin (L-OHP)-induced colorectal cancer cell apoptosis in a p53-independent manner by inhibiting cell autophagy. Oxaliplatin 28-33 P53 Homo sapiens 81-84 25534115-4 2015 In this study, ASPP2 was found to enhance L-OHP-induced apoptosis in HCT116 p53(-/-) cells in a p53-independent manner. Oxaliplatin 42-47 P53 Homo sapiens 76-79 25922718-5 2015 RESULTS: We found that CK could significantly enhance cisplatin-induced p53 expression and activity in two lung cancer cell lines, H460 and A549. ginsenoside M1 23-25 P53 Homo sapiens 72-75 26312880-8 2015 FINDINGS: AZD6738 provided potent and specific inhibition of ATR signalling with compensatory activation of ATM/p53 pathway in cycling CLL cells in the presence of genotoxic stress. ceralasertib 10-17 P53 Homo sapiens 112-115 26312880-9 2015 In p53 or ATM defective cells, AZD6738 treatment resulted in replication fork stalls and accumulation of unrepaired DNA damage, as evidenced by gammaH2AX and 53BP1 foci formation, which was carried through into mitosis, resulting in cell death by mitotic catastrophe. ceralasertib 31-38 P53 Homo sapiens 3-6 26312880-10 2015 AZD6738 displayed selective cytotoxicity towards ATM or p53 deficient CLL cells, and was highly synergistic in combination with cytotoxic chemotherapy. ceralasertib 0-7 P53 Homo sapiens 56-59 26312880-11 2015 This finding was confirmed in primary xenograft models of DDR-defective CLL, where treatment with AZD6738 resulted in decreased tumour load and selective reduction of CLL subclones with ATM or TP53 alterations. ceralasertib 98-105 P53 Homo sapiens 193-197 25932127-9 2015 On the molecular level, tanshinone IIA administration altered the expression of apoptosis-related proteins such as p53, Bax, Bcl-2 and cyto C.

QB 102 30-46 P53 Homo sapiens 16-19 25311224-7 2015 The resistant profile caused by p53 defect also caused a cell type-specific response to PA pool depletion and SSAT overexpression. Polyamines 88-90 P53 Homo sapiens 32-35 25550548-0 2015 Influence of p53 status on the effects of boron neutron capture therapy in glioblastoma. Boron 42-47 P53 Homo sapiens 13-16 25550548-2 2015 We studied the relationship between the p53 gene and the biological effects of boron neutron capture therapy (BNCT). Boron 79-84 P53 Homo sapiens 40-43 25603814-0 2015 Growth suppression and cell death by pyridoxal is dependent on p53 in the human breast cancer cell line MCF-7. Pyridoxal 37-46 P53 Homo sapiens 63-66 25603814-7 2015 The cell growth suppression by 0.5 mM PL did not occur when p53 expression was knocked down using siRNA. Pyridoxal 38-40 P53 Homo sapiens 60-63 25603814-8 2015 Together, these data suggest that PL accumulate p53 and PL-induced cell growth suppression is dependent on p53 in MCF-7 breast cancer cells. Pyridoxal 34-36 P53 Homo sapiens 48-51 25603814-8 2015 Together, these data suggest that PL accumulate p53 and PL-induced cell growth suppression is dependent on p53 in MCF-7 breast cancer cells. Pyridoxal 34-36 P53 Homo sapiens 107-110 25603814-8 2015 Together, these data suggest that PL accumulate p53 and PL-induced cell growth suppression is dependent on p53 in MCF-7 breast cancer cells. Pyridoxal 56-58 P53 Homo sapiens 107-110 25821561-7 2015 Treatment of A375 and Hs294t cells with GTPs resulted in a decrease in the levels of cyclins and cyclin dependent kinases of G1 phase of cell cycle whereas upregulated the levels of tumor suppressor proteins (Cip1/WAF1/p21, p16 and p53). gtps 40-44 P53 Homo sapiens 232-235 25179905-5 2014 Following 2-MeO-E2 treatment, only HCT116 (p53(+/+)) cells exhibited an enhancement in the levels of p53, p-p53 (Ser-15), p21(WAF1/CIP1), and Bax; however, the Bak level remained relatively constant in both cell types, and the Bcl-2 level decreased only in HCT116 (p53(+/+)) cells. 2-meo 10-15 P53 Homo sapiens 43-46 25179905-5 2014 Following 2-MeO-E2 treatment, only HCT116 (p53(+/+)) cells exhibited an enhancement in the levels of p53, p-p53 (Ser-15), p21(WAF1/CIP1), and Bax; however, the Bak level remained relatively constant in both cell types, and the Bcl-2 level decreased only in HCT116 (p53(+/+)) cells. 2-meo 10-15 P53 Homo sapiens 101-104 25179905-5 2014 Following 2-MeO-E2 treatment, only HCT116 (p53(+/+)) cells exhibited an enhancement in the levels of p53, p-p53 (Ser-15), p21(WAF1/CIP1), and Bax; however, the Bak level remained relatively constant in both cell types, and the Bcl-2 level decreased only in HCT116 (p53(+/+)) cells. 2-meo 10-15 P53 Homo sapiens 101-104 25179905-5 2014 Following 2-MeO-E2 treatment, only HCT116 (p53(+/+)) cells exhibited an enhancement in the levels of p53, p-p53 (Ser-15), p21(WAF1/CIP1), and Bax; however, the Bak level remained relatively constant in both cell types, and the Bcl-2 level decreased only in HCT116 (p53(+/+)) cells. 2-meo 10-15 P53 Homo sapiens 101-104 25521755-8 2014 Moreover, suppression of HDAC3 by either siRNA or a potent HDAC3 inhibitor (MS-275) inhibited cell proliferation, increased p53 acetylation and transcription activity. entinostat 76-82 P53 Homo sapiens 124-127 25242357-5 2014 Moreover, in the presence of cycloheximide, KLF9 significantly increased p53 stability in HCC cells. Cycloheximide 29-42 P53 Homo sapiens 73-76 25375376-6 2014 The suppression was dependent on the p53 response, which is triggered by the impairment of the complex III-dependent de novo biosynthesis of pyrimidines by mitochondrial dihydroorotate dehydrogenase.

Acrolein 23-31 P53 Homo sapiens 79-82 24747221-9 2014 Acrolein-induced down-regulation of WRN protein was rescued by p53 knockdown or proteasome inhibition. Acrolein 0-8 P53 Homo sapiens 63-66 24747221-11 2014 CONCLUSIONS: These results suggest that acrolein induces p53-mediated cellular senescence accompanied by enhanced telomere attrition and WRN protein down-regulation. Acrolein 40-48 P53 Homo sapiens 57-60 23625588-5 2014 Fenofibrate inhibited cell proliferation in both TP53 wild type and deficient lung cancer cells. Fenofibrate 0-11 P53 Homo sapiens 49-53 23625588-7 2014 An additive effect against cell proliferation by budesonide and fenofibrate combination was observed only in TP53 wild type A549 cancer cells. Fenofibrate 64-75 P53 Homo sapiens 109-113 24633417-0 2014 Delivery of a monomeric p53 subdomain with mitochondrial targeting signals from pro-apoptotic Bak or Bax. bakuchiol 94-97 P53 Homo sapiens 24-27 24633417-9 2014 The apoptotic mechanism of p53-BakMTS and DBD-BakMTS was Bak dependent. bakuchiol 31-34 P53 Homo sapiens 27-30 25023790-8 2014 RESULTS: beta-OH-S infusion prior to reperfusion reduced coronary and cardiac oxidative DNA-damage, diminished neutrophil infiltration at the site of ischemia, preserved mitochondrial membrane potential and reduced apoptosis in the ischemic myocardium (lower mRNA levels of Fas, casp8, p53, and casp3 and mitochondrial-p-Bcl2; and reduced TUNEL and active caspase-3; p<0.05 vs. vehicle/control). beta-oh-s 9-18 P53 Homo sapiens 286-289 24960055-5 2014 Moreover, HBCD and PCBs could induce the transcriptional activity of NF-kappab and suppress the p53 expression in HepG2 and MHCC97H cells. Polychlorinated Biphenyls 19-23 P53 Homo sapiens 96-99 24960055-6 2014 In MHCC97L cells, however, opposite changes for NF-kappaB protein expression, NF-kappaB transcriptional activity, and p53/Mdm4 expression were observed after HBCD and PCBs exposure.

Itraconazole 57-60 P53 Homo sapiens 104-107 21149266-6 2011 Using these cells, we demonstrated that aminoglycoside treatment stabilized the mutant mRNA, which would otherwise have been degraded by non-sense-mediated decay, resulting in the production of a functional full-length p53 protein. Aminoglycosides 40-54 P53 Homo sapiens 219-222 21149266-7 2011 Finally, we showed that aminoglycoside treatment decreased the viability of cancer cells specifically in the presence of nonsense-mutated p53 gene. Aminoglycosides 24-38 P53 Homo sapiens 138-141 33960434-6 2021 SP600125 also inhibited mRNA levels for all the aforementioned proteins, while SB203580 only affected p53 mRNA.

RG7388 62-68 P53 Homo sapiens 158-161 21035490-5 2011 Thus, we propose that regulation of bioactive sphingolipid signaling molecules could be of therapeutic benefit in the treatment of p53-dependent cancers. Sphingolipids 46-58 P53 Homo sapiens 131-134 31004033-6 2019 RG7388 potently decreased viability in p53-functional CLL cells, whereas p53-non-functional samples were more resistant to the drug.

Daunorubicin 138-150 P53 Homo sapiens 64-67 21976978-4 2011 p53 molecules were anchored to gold nanoparticles by means of the bifunctional linker 4-aminothiophenol (4-ATP). 4-aminothiophenol 86-103 P53 Homo sapiens 0-3 33876223-5 2021 The evolution pattern towards t-MN is then a complex process, shaped by the type of cancer therapy, the aging process, and the individual exposures, that favor additional hits, such as the acquisition of TP53 mutations and unfavorable karyotype abnormalities. t-mn 30-34 P53 Homo sapiens 204-208 31819692-6 2019 Methylation-specific polymerase chain reaction (MS-PCR) technique was used to define the methylation status of the TP53 gene promoter that encompasses DNA extraction, bisulfite conversion, conventional PCR amplification, running on agarose gel and documentation. hydrogen sulfite 167-176 P53 Homo sapiens 115-119 21976978-4 2011 p53 molecules were anchored to gold nanoparticles by means of the bifunctional linker 4-aminothiophenol (4-ATP). 4-aminothiophenol 105-110 P53 Homo sapiens 0-3 31683960-7 2019 Treatment of MDA-MB-231 cells with fruit ethyl acetate fraction (RSF EtOAc) increased expression 11of P53, Bax and activation of caspase 3/7.

Ceramides 15-23 P53 Homo sapiens 230-233 33205006-10 2020 Suppression of ceramide glycosylation significantly decreased Gb3-cSrc in GEMs, beta-catenin, and methyltransferase-like 3 for m6A RNA methylation, thus altering pre-mRNA splicing, resulting in upregulated expression of wild-type p53 protein, but not mutants, in cells carrying p53 R273H. Ceramides 15-23 P53 Homo sapiens 278-281 30501707-12 2018 Multivariate logistic regression model showed that the complex karyotype, Plt count doubling after 1 course treatment, TP53 mulation and high expression of hENT1 mRNA were the independent prognostic factors for predicting the CR after decitabine treatment. Decitabine 235-245 P53 Homo sapiens 119-123 32705198-8 2020 Moreover, the expression levels of p53, Bax, apoptotic peptidase activating factor 1, cytochrome C, cleaved caspase-3/9 and cleaved poly (ADP-ribose) polymerase were upregulated, and the expression levels of Bcl-2, Bcl-xl and phosphorylated ATM serine/threonine kinase were downregulated by aconitine.

N-acetylgalactosaminuronic acid 23-29 P53 Homo sapiens 13-16 30483050-7 2018 We found that treatment of 400 muM GM elicited the formation of ROS, which, in turn, led to PINK1 degradation, parkin recruitment, autophagy formation, an increase of p53 and cleaved-caspase 3 in HEI-OC1 cells and murine HCs. Gentamicins 35-37 P53 Homo sapiens 167-170 30483050-9 2018 Moreover, PINK1 interference contributed to a decrease of autophagy but an increase of p53 level in HEI-OC1 cells in response to GM stimulus.

RG7388 10-21 P53 Homo sapiens 68-71 30352966-6 2018 In the present study, we show that secondary resistance occurs also after treatment of p53wt cells with idasanutlin (RG7388, RO5503781), which is the only MDM2 antagonist that has passed phase II and entered phase III clinical trials, so far. RG7388 104-115 P53 Homo sapiens 87-90 32373892-7 2020 Moreover, linc-ROR siRNA also down-regulated the PI3K/AKT pathway in arsenite-transformed HaCaT cells, and treatment with AKT inhibitor wortmannin restored P53 activity, implying that linc-ROR inhibits P53 activity by activating the PI3K/AKT pathway. Wortmannin 136-146 P53 Homo sapiens 202-205 30352966-7 2018 Idasanutlin strongly activates p53, as evidenced by the induction of p21 expression and potent cell cycle arrest in all the three cell lines tested, i.e., MCF-7, U-2 OS, and SJSA-1. RG7388 0-11 P53 Homo sapiens 31-34 30352966-12 2018 Thus, although idasanutlin presents much improved activities compared to its precursor, it displays the similar weaknesses, which are limited elimination of cancer cells and the generation of p53-mutated drug-resistant subpopulations.

Ceramides 59-67 P53 Homo sapiens 239-242 30578766-7 2019 Concordantly, suppression of ceramide glycosylation repressed METTL3 expression and m6A formation in p53 pre-mRNA, thus sensitizing cells carrying R273H to anticancer drugs. Ceramides 29-37 P53 Homo sapiens 101-104 19046801-12 2009 Mutations of p53 determined in NHL cases (30%) were of Arg-176 (1/20: 5%), Phe-238 (1/20: 5%), Ser-249 (2/20; 10%), Lys-249 (1/20: 5%) and Phe-250 (1/20: 5%). Phenylalanine 139-142 P53 Homo sapiens 13-16 30578766-9 2019 Suppressing both RNA methylation and ceramide glycosylation might constitute an efficacious and specific approach for targeting TP53 missense mutations coding for a G > A transition, thereby improving cancer treatments. Ceramides 37-45 P53 Homo sapiens 128-132 19064630-6 2009 To better understand the mechanism by which PUVA treatment induces p53, we exposed human skin fibroblasts with PUVA under conditions that differentially produce monoadducts and ICLs and found that psoralen-induced ICLs induced phosphorylation of the Ser-15 site of p53 and apoptosis much more effectively than psoralen-induced monoadducts. puva 44-48 P53 Homo sapiens 67-70 30766866-3 2019 Spiropyrazoline oxindoles have previously been shown to induce apoptosis and cell cycle arrest, as well as upregulate p53 steady-state levels, while decreasing its main inhibitor MDM2 in the HCT116 human colorectal carcinoma cell line. spiropyrazoline oxindoles 0-25 P53 Homo sapiens 118-121 30598450-12 2019 Combining MDM2 inhibitors with lenalidomide targeting CK1alpha or an MDM4 inhibitor caused synergistic activation of p53, leading to an apoptotic response in MCV-positive MCC cells and MCC-derived xenografts in mice.

RG7388 9-20 P53 Homo sapiens 137-140 19064630-6 2009 To better understand the mechanism by which PUVA treatment induces p53, we exposed human skin fibroblasts with PUVA under conditions that differentially produce monoadducts and ICLs and found that psoralen-induced ICLs induced phosphorylation of the Ser-15 site of p53 and apoptosis much more effectively than psoralen-induced monoadducts. puva 44-48 P53 Homo sapiens 265-268 29483845-12 2018 A rescue in the expression of both MLL genes was observed in KCL22S, a CML cell line sensitive to IM, after treatment with dasatinib or nilotinib which was associated with a higher rate of apoptosis, an enhanced expression of p21 (CDKN1A) and a concomitant decrease in the expression of CDK2, CDK4 and Cyclin B1 (CCNB1) in comparison to untreated KCL22S control or IM resistant KCL22R cell line, which suggests involvement of p53 regulated pathway. kcl22s 61-67 P53 Homo sapiens 426-429 19064630-6 2009 To better understand the mechanism by which PUVA treatment induces p53, we exposed human skin fibroblasts with PUVA under conditions that differentially produce monoadducts and ICLs and found that psoralen-induced ICLs induced phosphorylation of the Ser-15 site of p53 and apoptosis much more effectively than psoralen-induced monoadducts. puva 111-115 P53 Homo sapiens 67-70 30622244-3 2019 In this study, we found that EPO suppresses p53-dependent apoptosis induced by genotoxic (daunorubicin, doxorubicin, and gamma-radiation) and non-genotoxic (nutlin-3a) agents and induces a senescence-like state in myeloid leukemia cells. Daunorubicin 90-102 P53 Homo sapiens 44-47 19060927-8 2009 Although p53 has been reported to be a target of Sirt1, genetic p53 knockdowns showed that the Sirt1-dependent proapoptotic effect of Salermide is p53-independent.

Taurine 15-22 P53 Homo sapiens 91-94 29451912-12 2018 In summary, mutation analysis in TP53 plays a minor role in the subgroup of high-risk GIST before adjuvant treatment with imatinib. Imatinib Mesylate 122-130 P53 Homo sapiens 33-37 19060927-8 2009 Although p53 has been reported to be a target of Sirt1, genetic p53 knockdowns showed that the Sirt1-dependent proapoptotic effect of Salermide is p53-independent.

Ruthenium Compounds 8-26 P53 Homo sapiens 125-128 19202565-9 2009 Moreover, DADS-induced apoptosis was also prevented by treatment with oligomycin, which is known to prevent p53-dependent apoptosis by reducing ROS levels in mitochondria. Oligomycins 70-80 P53 Homo sapiens 108-111 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. Camphor 105-112 P53 Homo sapiens 218-221 30301863-7 2019 Corroborating the basis of sensitivity, transcriptional profiling of platinum-resistant ARID1A-mutated HT1197 cells treated with panobinostat reveals negative enrichment for both cyto-proliferative (MYC and E2F targets) and DNA repair gene sets, and positive enrichment for TP53 and inflammatory gene sets. Panobinostat 129-141 P53 Homo sapiens 274-278 29429512-12 2018 RESULTS: The saline-treated HCC group (with prior 15 week DEN exposure) showed higher levels of wnt4 and p53 gene expression (1.59 and 1.36 fold, respectively) and increased percentage in OV6+ progenitor cells (+4.9% in absolute terms) compared to saline-treated controls (p < 0.01, ANOVA). Diethylnitrosamine 58-61 P53 Homo sapiens 105-108 18787402-2 2008 Here we show that combining the three sage bioactive compounds, Linalyl acetate (Ly), Terpeniol (Te) and Camphor (Ca), caused synergistic inhibition of the growth of two isogenic human colon cancer cell lines HCT-116 (p53(+/+) and p53(-/-)) and had no effect on growth of FHs74Int normal human intestinal cell line. Camphor 105-112 P53 Homo sapiens 231-234 29568362-6 2018 The antitumor activity was partly due to NO-cGMP dependent pathway, contributing to reduced cell number and apoptosis, and partly to the salicylaldehyde moiety and reactive oxygen species (ROS) activated ERK1/2 signaling converging on p53 dependent caspase-3 cleavage. salicylaldehyde 137-152 P53 Homo sapiens 235-238 29370077-0 2018 p53 Gene (NY-CO-13) Levels in Patients with Chronic Myeloid Leukemia: The Role of Imatinib and Nilotinib. Imatinib Mesylate 82-90 P53 Homo sapiens 0-3 30577494-6 2018 Trametinib synergizes with MDM2 inhibitors through a novel DUSP6 mechanism in BRAFV600E and p53WT melanoma cells, in which DUSP6 regulation of p53 phosphorylation is mediated by ATM. trametinib 0-10 P53 Homo sapiens 92-95 30577494-6 2018 Trametinib synergizes with MDM2 inhibitors through a novel DUSP6 mechanism in BRAFV600E and p53WT melanoma cells, in which DUSP6 regulation of p53 phosphorylation is mediated by ATM. trametinib 0-10 P53 Homo sapiens 143-146 29370077-5 2018 The purpose of the present study was to evaluate the differential effect of imatinib and nilotinib on p53 gene serum levels in patients with CML. Imatinib Mesylate 76-84 P53 Homo sapiens 102-105 18787402-3 2008 In p53(+/+) cells, the combination of Ly + Te + Ca (10(-3) M of each) caused significant accumulation of cells in PreG(1) (64% at 48 hours); less preG(1) increase was observed in response to Ly + Te (25%) or Ly + Ca (14%). linalyl acetate 38-42 P53 Homo sapiens 3-6 29370077-10 2018 Patients with CML that were treated with either imatinib or nilotinib showed insignificant differences in most of the hematological profile (p > 0.05) whereas, p53 serum levels were high (3.22 +- 1.99 ng/mL) in nilotinib-treated patients and relatively low (1.18 +- 0.19 ng/mL) in imatinib-treated patients (p = 0.0001). Imatinib Mesylate 48-56 P53 Homo sapiens 163-166 29370077-11 2018 CONCLUSIONS: Nilotinib is more effective than imatinib in raising p53 serum levels in patients with chronic myeloid leukemia. Imatinib Mesylate 46-54 P53 Homo sapiens 66-69 30225664-12 2018 In addition, taurine increased the levels of PTEN (phosphatase and tensin homolog deleted on chromosome 10) and p53, and reduced phosphorylated Akt (protein kinase B). Taurine 13-20 P53 Homo sapiens 112-115 19181008-4 2008 Previously, an animal model was developed by our research group to investigate the expression of three genes c-myc, Ha-ras and p53 as early molecular epidemiological biomarkers of carcinogenic exposure or carcinogenesis caused by DMBA (dimethylbenz[alpha]anthracene). 6,11-dimethylbenzo(b)naphtho(2,3-d)thiophene 230-234 P53 Homo sapiens 127-130 18296682-4 2008 In addition, naringin treatment strongly induced p21WAF1 expression, independent of the p53 pathway, and downregulated expression of cyclins and cyclin dependent kinases (CDKs). naringin 13-21 P53 Homo sapiens 88-91 30466751-3 2018 Decitabine is emerging as an alternative treatment option for patients with TP53 mutated AML, although the agent has not been associated with deep molecular remissions and requires additional consolidation. Decitabine 0-10 P53 Homo sapiens 76-80 29277758-3 2018 The goal of this study was to investigate the chemotherapeutic effects of sphingosine on PAX3-FOXO1-positive ARMS cells [tumor protein p53 (TP53)-mutated RH30 and TP53 wild-type RH18 cells]. Sphingosine 74-85 P53 Homo sapiens 135-138 18548093-6 2008 We suggest that PI-103 actively enhances downstream p53 signaling and that a combination strategy aimed at inhibiting PI3K/Akt/mTOR signaling and activating p53 signaling is potentially effective in AML, where TP53 mutations are rare and downstream p53 signaling is intact. PI103 16-22 P53 Homo sapiens 52-55 29368980-5 2018 SK1-I, an analog of sphingosine and isozyme-specific SPHK1 inhibitor, suppressed cancer cell growth and clonogenic survival in a TP53-dependent manner. Sphingosine 20-31 P53 Homo sapiens 129-133 29115606-3 2018 However, its regulation of chemosensitivity to gemcitabine (GEM) and oxaliplatin (OXA) in p53-deficient PDAC remains unclear. gemcitabine 47-58 P53 Homo sapiens 90-93 30484863-8 2018 Taken together, we propose that LBH589 inhibits ESCC cell proliferation mainly through inducing cell cycle arrest by increasing p21 and decreasing cyclin D1 in a p53-independent manner. Panobinostat 32-38 P53 Homo sapiens 162-165 29115606-3 2018 However, its regulation of chemosensitivity to gemcitabine (GEM) and oxaliplatin (OXA) in p53-deficient PDAC remains unclear. gemcitabine 60-63 P53 Homo sapiens 90-93 18345033-0 2008 P53-mediated upregulation of DcR1 impairs oxaliplatin/TRAIL-induced synergistic anti-tumour potential in colon cancer cells. Oxaliplatin 42-53 P53 Homo sapiens 0-3 29115606-3 2018 However, its regulation of chemosensitivity to gemcitabine (GEM) and oxaliplatin (OXA) in p53-deficient PDAC remains unclear. pdac 104-108 P53 Homo sapiens 90-93 29115632-8 2018 Furthermore, combination treatment with SAHA and 5-Aza-CdR significantly increased expression of TP53 and P16. Vorinostat 40-44 P53 Homo sapiens 97-101 30086334-5 2018 TP53 alterations were more common in patients with PCs in BM (45.4% versus 18.7%; P = .0049), as was a complex karyotype (26.4% versus 9%; P = .019). pcs 51-54 P53 Homo sapiens 0-4 29333130-3 2017 Here, curcumin, flavokawain B, and alpinetin were docked against the crystal structure of R273H mutant p53 in silico. flavokawain B 16-29 P53 Homo sapiens 103-106 18345033-1 2008 Oxaliplatin has emerged as a major chemotherapeutic drug in the treatment of advanced colorectal cancer, yet like most conventional cancer therapeutics, its efficacy is often compromised due to p53 mutations. Oxaliplatin 0-11 P53 Homo sapiens 194-197 29333130-4 2017 Consequently, all the compounds bind to the cavity of R273H mutant p53 with a dissociation constant estimated to have 36.57, 70.77, and 75.11 microM for curcumin, flavokawain B, and alpinetin, respectively. flavokawain B 163-176 P53 Homo sapiens 67-70 30546426-11 2018 Markedly decreased Akt phosphorylation and cyclin D1 levels and increased p53 levels were detected when cells were transfected with miR-128 mimics. mir-128 132-139 P53 Homo sapiens 74-77 18345033-5 2008 Impaired TRAIL-induced cell death resulted from a strong p53 dependent, oxaliplatin-mediated, DcR1 receptor expression increase. Oxaliplatin 72-83 P53 Homo sapiens 57-60 30546426-14 2018 In conclusion, the results suggested that miR-128 was a specific negative regulator of RPN2, which regulated colorectal cancer cell proliferation and migration by affecting the Akt-p53-cyclin pathway. mir-128 42-49 P53 Homo sapiens 181-184 29089230-1 2017 A series of novel amino acid ester derivatives of 2,3-substituted isoindolinones was synthesized and evaluated for p53-mediated apoptotic activity. amino acid ester 18-34 P53 Homo sapiens 115-118 18345033-6 2008 According to our finding, downregulation of DcR1 using siRNA, in p53 wild-type colon cancer cells, restored oxaliplatin/TRAIL synergistic apoptotic activity. Oxaliplatin 108-119 P53 Homo sapiens 65-68 18345033-8 2008 Altogether we demonstrate for the first time that p53 negatively regulates oxaliplatin-mediated TRAIL-induced apoptotic activity through DcR1 upregulation. Oxaliplatin 75-86 P53 Homo sapiens 50-53 29143344-4 2017 5-Aza-dC inhibited E6 and E7 expression and up-regulated p53, p21, and Rb expression. Decitabine 0-8 P53 Homo sapiens 57-60 18345033-9 2008 Our findings could have important implications for future therapeutic strategies, and suggest that the association oxaliplatin/TRAIL should be restricted to patients harbouring a non-functional p53 protein. Oxaliplatin 115-126 P53 Homo sapiens 194-197 30454541-14 2018 Furthermore, Western blot analysis showed that microwave hyperthermia combined with gemcitabine could up-regulate the p53, Caspase-3, Cleaved-Caspase-3, Cleaved-PARP and Bax protein expression. gemcitabine 84-95 P53 Homo sapiens 118-121 30068711-6 2018 Trametinib and radiotherapy both induced senescence in a p53-dependent manner, but in WT LKB1 cells, the combination also activated the AMPK-autophagy pathway to rescue damaged cells from senescence. trametinib 0-10 P53 Homo sapiens 57-60 28733702-8 2017 Finally, we tested the ability of CXCR4 and FAK inhibitors (WZ811 and PF-573228, respectively) to suppress the migratory and invasive potential of p53/PTEN deficient NSCLC cells, in vitro and in vivo using metastatic models of human NSCLC. N,N'-di-2-pyridinyl-1,4-benzenedimethanamine 60-65 P53 Homo sapiens 147-150 18508032-9 2008 Cell cycle distribution after exposure to oxaliplatin showed arrest in G2/M (A2780) or in S-phase (LoVo-92) for wt-p53 cells.

Polyethyleneimine 158-174 P53 Homo sapiens 73-76 30462771-13 2018 Knockdown of p53 or employing the caspase inhibitor, Boc-D-FMK, reversed the effect of oridonin on cell viability and apoptosis-related protein expression. Boc-D-FMK 53-62 P53 Homo sapiens 13-16 28618116-1 2017 Mutations in the tumor suppressor p53 are highly prevalent in cancers and are known to influence the sensitivity of cells to various chemotherapeutics including the anti-cancer candidates 1,25-dihydrovitamin D3 [1,25D3] and metformin. 1,25-dihydrovitamin d3 188-210 P53 Homo sapiens 34-37 18511169-6 2008 Specific ATM inhibitor, caffeine, significantly decreased KTA-mediated G2/M arrest by inhibiting the phosphorylation of p53 (Serine15) and Chk2. Caffeine 24-32 P53 Homo sapiens 120-123 30405800-8 2018 Notably, the combination of dinaciclib and DOX inhibited cell growth and promoted senescence by transforming the suppressive effects of the ATM/Chk2/p53/p21 signaling pathway and enhancing the p16 signaling pathway. dinaciclib 28-38 P53 Homo sapiens 149-152 29035366-4 2017 Consequently, targeting of EGFR-driven glucose metabolism in combination with pharmacological stabilization of p53 with the brain-penetrant small molecule idasanutlin resulted in synthetic lethality in orthotopic glioblastoma xenograft models. RG7388 155-166 P53 Homo sapiens 111-114 18645022-0 2008 Differential antiproliferative mechanisms of novel derivative of benzimidazo[1,2-alpha]quinoline in colon cancer cells depending on their p53 status. benzimidazo[1,2-alpha]quinoline 65-96 P53 Homo sapiens 138-141 18440285-5 2008 Caffeine increased apoptosis levels and inhibited p53 activation in proliferating cells, suggesting a protective role for p53. Caffeine 0-8 P53 Homo sapiens 50-53 29051574-7 2017 Furthermore, FLO also induces G0/G1 cell cycle arrest via increase of p21 levels through activating ROS/p53/p21 pathway. florfenicol 13-16 P53 Homo sapiens 104-107 29051574-9 2017 In addition, FLO-induced upregulation of cytosolic p53 may contribute to mitophagy deficiency via regulation of Parkin recruitment. florfenicol 13-16 P53 Homo sapiens 51-54 30283098-2 2018 ROS and RNS can influence tumor cell malignancy via the redox-regulated transcription factor NF-kappaB, whose activation is further regulated by the mutation status of p53. Reactive Nitrogen Species 8-11 P53 Homo sapiens 168-171 30283098-5 2018 Nanoparticle activity was related to the decreased level of intracellular ROS and RNS, which downregulated NF-kappaB signaling depending on the p53 status of the cell line. Reactive Nitrogen Species 82-85 P53 Homo sapiens 144-147 18440285-5 2008 Caffeine increased apoptosis levels and inhibited p53 activation in proliferating cells, suggesting a protective role for p53. Caffeine 0-8 P53 Homo sapiens 122-125 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Ceramides 156-164 P53 Homo sapiens 43-46 18483381-4 2008 RESULTS: In this report, we show that the HDIs trichostatin A, sodium butyrate, and low nanomolar doses of LAQ824 combined with the glycolysis inhibitor 2-deoxy-d-glucose induce strong apoptosis in cancer cell lines of brain, breast, and cervix in a p53-independent manner. LAQ824 107-113 P53 Homo sapiens 250-253 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Ceramides 156-164 P53 Homo sapiens 261-264 30059758-4 2018 Here, we show that in human wild-type (wt) p53 HCT-116 colon cancer cells treatment with oxaliplatin or 5-fluorouracil (5-FU) leads to a strong increase in ceramide synthase 5 (CerS5) expression and C16:0-ceramide levels, which was not shown in HCT-116 lacking p53 expression (HCT-116 p53-/-). Ceramides 156-164 P53 Homo sapiens 261-264 30059758-6 2018 By contrast, in the p53-deficient cells CerS2 expression and CerS2-related C24:0- and C24:1-ceramide levels were elevated which is possibly related to enhanced polyadenylation of the CerS2 transcript in these cells.

Acriflavine 61-72 P53 Homo sapiens 75-78 27863490-7 2016 Interestingly, we found that a lower dose of SAHA (1 muM and 2.5 muM) inhibited GSCs via cell cycle arrest and induced premature senescence through p53 up-regulation and p38 activation. Vorinostat 45-49 P53 Homo sapiens 148-151 27863490-8 2016 CONCLUSION: SAHA induces apoptosis and functions as a potent modulator of senescence via the p38-p53 pathway in GSCs. Vorinostat 12-16 P53 Homo sapiens 97-100 27904708-6 2016 We found that abnormal expression of CPA4 was positively associated with Ki67 (P=0.002) and reversely correlated with p53 (P=0.035) in GC. cpa4 37-41 P53 Homo sapiens 118-121 26993060-8 2016 CONCLUSIONS: Obinutuzumab plus idasanutlin enhanced cell death of p53 wild-type tumour cells vs. rituximab plus idasanutlin without affecting obinutuzumab-mediated ADCC or B-cell depletion and showed robust antitumour efficacy in xenograft models, strongly supporting the investigation of this combination in clinical trials. RG7388 31-42 P53 Homo sapiens 66-69 27644244-8 2016 Furthermore, the p38/mitogen-activated protein kinase (MAPK) inhibitor SB203580 reversed the increase of the expression level of p38, p-cdc2 (Tyr15), cleaved caspase 3, cleaved PARP, p-p53, and p53 and reversed the decrease in cdc25B expression. SB 203580 71-79 P53 Homo sapiens 185-188 27644244-8 2016 Furthermore, the p38/mitogen-activated protein kinase (MAPK) inhibitor SB203580 reversed the increase of the expression level of p38, p-cdc2 (Tyr15), cleaved caspase 3, cleaved PARP, p-p53, and p53 and reversed the decrease in cdc25B expression. SB 203580 71-79 P53 Homo sapiens 194-197 27601937-7 2016 Upon re-introduction of wild-type TP53, SAHA-treated ESS-1 cells underwent immediate apoptotic cell death as supported by upregulation of PUMA and caspase-9 as well as by activation of caspases-3 and -7 and PARP-1 cleavage. Vorinostat 40-44 P53 Homo sapiens 34-38 27601937-11 2016 Using MES-SA cells with RNAi-silenced p53 expression and several p53-deficient tumor cell lines undergoing SAHA-induced autophagy, we could generally validate our finding suggesting an inhibitory role for p53 in the autophagic pathway in response to SAHA treatment. Vorinostat 107-111 P53 Homo sapiens 65-68 27601937-11 2016 Using MES-SA cells with RNAi-silenced p53 expression and several p53-deficient tumor cell lines undergoing SAHA-induced autophagy, we could generally validate our finding suggesting an inhibitory role for p53 in the autophagic pathway in response to SAHA treatment. Vorinostat 107-111 P53 Homo sapiens 65-68 27601937-12 2016 CONCLUSIONS: Conclusively, these results could identify cytoplasmic p53 protein as a molecular switch that directly mediates the cytotoxic response of SAHA and thus open new therapeutic avenues. Vorinostat 151-155 P53 Homo sapiens 68-71 26258493-5 2016 DNA demethylation with 5-aza-2"-deoxycytidine restored GLS2 mRNA and protein content in human GB cell lines with both mutated (T98G) and wild-type (U87MG) p53 and reduced the methylation of CpG1 (promoter region island), and CpG2 (first intron island) in both cell lines. Decitabine 23-45 P53 Homo sapiens 155-158 27425828-0 2016 Low doses of arsenic, via perturbing p53, promotes tumorigenesis. Arsenic 13-20 P53 Homo sapiens 37-40 27425828-3 2016 In this study, we demonstrate that low doses of arsenic exposure mitigate or mask p53 function and further perturb intracellular redox state, which triggers persistent endoplasmic reticulum (ER) stress and activates UPR (unfolded protein response), leading to transformation or tumorigenesis. Arsenic 48-55 P53 Homo sapiens 82-85 27425828-4 2016 Thus, the results suggest that low doses of arsenic exposure, through attenuating p53-regulated tumor suppressive function, change the state of intracellular redox and create a microenvironment for tumorigenesis. Arsenic 44-51 P53 Homo sapiens 82-85 27302066-8 2016 This study has shown that by direct transcriptional activation of CerS6, p53 can regulate specific ceramide biosynthesis, which contributes to the pro-apoptotic cellular response. Ceramides 99-107 P53 Homo sapiens 73-76 27461834-0 2016 P53 overexpression and Ki67-index are associated with outcome in ductal pancreatic adenocarcinoma with adjuvant gemcitabine treatment. gemcitabine 112-123 P53 Homo sapiens 0-3 27461834-6 2016 However, stratified analysis according to treatment arm revealed that the effect of deregulated p53 expression and high Ki67 expression was restricted to the disease free survival of patients treated with adjuvant gemcitabine. gemcitabine 214-225 P53 Homo sapiens 96-99 26640144-7 2016 Importantly, LBH589 treatment in combination with castration prevents mCRPC development and significantly prolongs survival following castration by enhancing p53 and androgen receptor acetylation and in turn sensitizing castration-resistant mesenchymal-like tumor cells to androgen deprivation therapy.

Radium 65-68 P53 Homo sapiens 95-98 27174050-5 2016 In the present study, we identified 9 Ru (II)-Arene Schiff-base (RAS) complexes able to induce p53-independent cytotoxicity and discuss structural features that are required for their p53-independent activity. Radium 65-68 P53 Homo sapiens 184-187 27174050-8 2016 This was despite significant differences in their physicochemical properties, suggesting that the iminoquinoline ligand, a common structural feature for all the complexes, is required for the p53-independent activity. iminoquinoline 98-112 P53 Homo sapiens 192-195 27235710-14 2016 Furthermore, the results of qRT-PCR showed that lupeol pre-treatment significantly (p<0.05) decreased mancozeb-induced expression of DNA damage (p53, MDM2, COX-2, GADD45alpha and p21) and increased expression of DNA repair responsive genes (hOGG1 and XRCC1) in CHLs. mancozeb 105-113 P53 Homo sapiens 148-151 26987571-6 2016 Moreover, the tumors treated with MG132/m showed higher levels of tumor suppressing proteins, hScrib and p53, as well as apoptotic degree, than tumors treated with free MG132. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 34-39 P53 Homo sapiens 105-108 26876786-3 2016 Further, SAHA and NaB decrease the phosphorylation, protein and mRNA levels of mutant p53 (mtp53) in TNBC cells. Vorinostat 9-13 P53 Homo sapiens 86-89 26876786-7 2016 The luciferase assay and ChIP analysis reveal that both SAHA and NaB can reduce the binding of transcription factor Yin Yang 1 (YY1) with the -102 to -96 position of human p53 promoter. Vorinostat 56-60 P53 Homo sapiens 172-175 26876786-9 2016 Further, SAHA and NaB can inhibit the association of HDAC8 and YY1, increase acetylation of residues 170-200 of YY1, then decrease its transcription activities, and finally suppress YY1 induced p53 transcription. Vorinostat 9-13 P53 Homo sapiens 194-197 26939786-11 2016 Thus, for the first time, these data highlighted the potential use of the diterpene in the sensitization of GBM cells to chemotherapy through a direct re-activation of p53 pathway. Diterpenes 74-83 P53 Homo sapiens 168-171 26987028-10 2016 The results showed that both GA and cisplatin changed the morphology, inhibited the growth and induced apoptosis in the H446 cells by inducing generation of ROS, disruption of MMP, downregulation of XIAP expression, and upregulation of Bax, Apaf-1, DIABLO and p53 expression. Gallium 29-31 P53 Homo sapiens 260-263 27044842-3 2016 The MTT cell viability assay showed that treatment with IMP1338 selectively inhibited HCT116, HCT116 p53(-/-), HT29, and A549 cancer cell proliferation compared to that of Beas2B normal epithelial cells. IMP1338 56-63 P53 Homo sapiens 101-104 27044842-7 2016 In addition, IMP1338 markedly induced the phosphorylation of histone H2AX and Chk1 in both cell lines while the combination of 5-fluorouracil (5-FU) and radiation inhibited the viability of HCT116, HCT116 p53(-/-), and HT29 cells compared to 5-FU or radiation alone. IMP1338 13-20 P53 Homo sapiens 205-208 26882972-6 2016 Moringin showed to be effective in inducing apoptosis through p53 and Bax activation and Bcl-2 inhibition. moringin 0-8 P53 Homo sapiens 62-65 26967821-7 2016 This analysis indicates that lenalidomide is active in patients with relapsed/refractory CLL with unfavorable genetic profiles, including TP53 inactivation or unmutated IGHV. Lenalidomide 29-41 P53 Homo sapiens 138-142 26775629-12 2016 CONCLUSION: IMQ induced ROS production to stimulate ATM/ATR pathways and contributed to p53-dependent apoptosis in a skin basal cell carcinoma cell line BCC/KMC1. Imiquimod 12-15 P53 Homo sapiens 88-91 26928575-7 2016 Our analysis provides an explanation why cancer cell lines known to have vastly diverse expression levels of Wip1 and PTEN exhibit a broad spectrum of responses to DNA damage: from a fast transition to a high level of p53 killer (a p53 phosphoform which promotes commitment to apoptosis) in cells characterized by high PTEN and low Wip1 levels to long-lasting p53 level oscillations in cells having PTEN promoter methylated (as in, e.g., MCF-7 cell line). phosphoform 236-247 P53 Homo sapiens 218-221 26928575-7 2016 Our analysis provides an explanation why cancer cell lines known to have vastly diverse expression levels of Wip1 and PTEN exhibit a broad spectrum of responses to DNA damage: from a fast transition to a high level of p53 killer (a p53 phosphoform which promotes commitment to apoptosis) in cells characterized by high PTEN and low Wip1 levels to long-lasting p53 level oscillations in cells having PTEN promoter methylated (as in, e.g., MCF-7 cell line). phosphoform 236-247 P53 Homo sapiens 232-235 26928575-7 2016 Our analysis provides an explanation why cancer cell lines known to have vastly diverse expression levels of Wip1 and PTEN exhibit a broad spectrum of responses to DNA damage: from a fast transition to a high level of p53 killer (a p53 phosphoform which promotes commitment to apoptosis) in cells characterized by high PTEN and low Wip1 levels to long-lasting p53 level oscillations in cells having PTEN promoter methylated (as in, e.g., MCF-7 cell line). phosphoform 236-247 P53 Homo sapiens 232-235 26772154-0 2016 LincRNAs and base modifications of p53 induced by arsenic methylation in workers.

Arsenic 131-133 P53 Homo sapiens 91-94 26772154-11 2016 These findings suggest potentially widespread roles of p53 and relative RNAs in arsenic workers, which may be caused by As metabolism. Arsenic 80-87 P53 Homo sapiens 55-58 27013776-7 2016 Furthermore, supplementation of 5-methyltetrahydrofolate to the dihydrofolate reductase knockdown cells could weaken the inhibitory effect of dihydrofolate reductase knockdown on cell proliferation, simultaneously, inducing the expression of p53 and p21(waf/cip1) falling back moderately. 5-methyltetrahydrofolate 32-56 P53 Homo sapiens 242-245 26953705-5 2016 A slight increase in promoter methylation of p53 in cord blood lymphocytes which correlated with arsenic accumulation in nails was observed in these exposed newborns. Arsenic 97-104 P53 Homo sapiens 45-48 16651407-9 2006 In addition, p53 induced VDR target genes in a vitamin D3-dependent manner. Cholecalciferol 47-57 P53 Homo sapiens 13-16 26756315-7 2016 On the other hand, mutant p53 RPMI7951 cell death occurred by PBD-GA-mediated mitochondria- and caspase-dependent pathways via lysosomal membrane permeabilization (LMP), but not through p53 signaling. Gallium 66-68 P53 Homo sapiens 26-29 26756315-7 2016 On the other hand, mutant p53 RPMI7951 cell death occurred by PBD-GA-mediated mitochondria- and caspase-dependent pathways via lysosomal membrane permeabilization (LMP), but not through p53 signaling.

[pt(bdi(qq))]cl 87-102 P53 Homo sapiens 18-21 15486204-6 2004 This study, using gel-mobility-shift assays, was undertaken to examine the interactions of active and latent p53 protein with DNA fragments and oligodeoxyribonucleotide duplexes modified by BBR3464 in a cell free medium and to compare these results with those describing the interactions of these proteins with DNA modified by cisplatin. BBR 3464 190-197 P53 Homo sapiens 109-112 15486204-7 2004 The results indicate that structurally different DNA adducts of BBR3464 and cisplatin exhibit a different efficiency to affect the binding affinity of the modified DNA to p53 protein. BBR 3464 64-71 P53 Homo sapiens 171-174 24514456-10 2014 In p53-null cells, [Pt(BDI(QQ))]Cl induces cell death through mitochondrial dysfunction. [pt(bdi(qq))]cl 19-34 P53 Homo sapiens 3-6 15486204-8 2004 It has been suggested that different structural perturbations induced in DNA by the adducts of BBR3464 and cisplatin produce a differential response to p53 protein activation and recognition and that a "molecular approach" to control of downstream effects such as protein recognition and pathways of apoptosis induction may consist in design of structurally unique DNA adducts as cell signals. BBR 3464 95-102 P53 Homo sapiens 152-155 24575839-0 2014 Phospho-aspirin (MDC-22) inhibits breast cancer in preclinical animal models: an effect mediated by EGFR inhibition, p53 acetylation and oxidative stress. mdc-22 17-23 P53 Homo sapiens 117-120 15298872-2 2004 Here we report an intermediate structure of the core domain of the tumor suppressor protein p53 (p53C) during equilibrium and kinetic folding/unfolding transitions induced by guanidinium chloride.

Vorinostat 26-36 P53 Homo sapiens 56-59 15326376-4 2004 We here show that inhibition of Chk1 but not of Chk2 in p21(-/-) and p53(-/-) cells caused a greater abrogation of G(2) block induced by ionizing radiation and cis-diamine-dichloroplatinum treatments and a greater sensitization to the same treatments than in the parental cell line with p53 and p21 wild type proteins. Platinum(II) chloride 172-188 P53 Homo sapiens 69-72 24281001-5 2014 RESULTS: Vorinostat was equally effective in p53 wild-type and null cells, whereas entinostat was less effective in p53 null cells. Vorinostat 9-19 P53 Homo sapiens 45-48 24281001-9 2014 CONCLUSION: These results demonstrate that vorinostat activates p53, but does not require p53 for inducing its anticancer action. Vorinostat 43-53 P53 Homo sapiens 64-67 24177958-7 2014 When these cells were simultaneously treated with a c-ABL kinase inhibitor, STI571, or a c-ABL-specific siRNA along with adriamycin, the p53-dependent p21 induction was dramatically diminished, even though p53 is substantially induced.

Cycloheximide 81-94 P53 Homo sapiens 29-32 24870784-0 2014 Rice bran phytic acid induced apoptosis through regulation of Bcl-2/Bax and p53 genes in HepG2 human hepatocellular carcinoma cells. Phytic Acid 10-21 P53 Homo sapiens 76-79 24870784-9 2014 PA treated HepG2 cells showed up-regulation of p53, Bax, Caspase-3 and -9, and down- regulation of Bcl-2 gene (p <= 0.01). Phytic Acid 0-2 P53 Homo sapiens 47-50 24870784-10 2014 At the IC50 (2.49 mM) of PA, the p53, Bax, Caspase-3 and-9 genes were up- regulated by 6.03, 7.37, 19.7 and 14.5 fold respectively. Phytic Acid 25-27 P53 Homo sapiens 33-36 15297424-6 2004 In cell lines with wild-type p53, treatment with the protein synthesis inhibitor cycloheximide (CHX) together with anti-CD95 overcame the resistance, suggesting the presence of a labile inhibiting protein.

Vinyl Chloride 132-134 P53 Homo sapiens 72-75 24236158-6 2013 In contrast, SAHA increased expression of Caspase-3, p21 and p53 mRNA, and upregulated acetyl-Histones H3 and H4, Caspase-8, and p53 proteins. Vorinostat 13-17 P53 Homo sapiens 61-64 24236158-6 2013 In contrast, SAHA increased expression of Caspase-3, p21 and p53 mRNA, and upregulated acetyl-Histones H3 and H4, Caspase-8, and p53 proteins. Vorinostat 13-17 P53 Homo sapiens 129-132 15116093-4 2004 Pretreatment of MCF7 cells with an ERK2 chemical inhibitor, PD98059 or U0126, blocked doxorubicin-induced p53 activation and suppressed phosphorylation of p53Thr55.

Ceramides 0-8 P53 Homo sapiens 48-51 24269881-6 2013 Ceramide treatment also upregulated (p<0.05) p53 and p21 protein expression, that was reversed by either pifithrin-alpha or shRNA for p53. Ceramides 0-8 P53 Homo sapiens 137-140 15041737-8 2004 These data suggest that p53 may be an important determinant of sensitivity to 5-FU and oxaliplatin but not CPT-11. Oxaliplatin 87-98 P53 Homo sapiens 24-27 14757188-1 2004 It has been recently shown that ionizing radiation (IR) and the mRNA synthesis inhibitor 5,6-dichloro-1-b-D-ribofuranosylbenzimidazole (DRB) act in synergy to induce p53-mediated transactivation of reporter plasmids in human cells [Oncogene 19 (2000) 3829]. 5,6-dichloro-1-b-d-ribofuranosylbenzimidazole 89-134 P53 Homo sapiens 166-169 24074410-2 2013 We sought to investigate the role of the p53-p21(waf1/cip1) pathway in relation to EZH2-mediated inhibition of PDAC. pdac 111-115 P53 Homo sapiens 41-44 14751246-1 2004 Caffeine has been widely described as a chemo/radiosensitizing agent, presumably by inhibiting DNA repair, and affecting preferentially cells with an altered p53 status. Caffeine 0-8 P53 Homo sapiens 158-161 14743382-6 2004 When their DNA is damaged, p53-defective tumor cells preferentially arrest in S or G2 phase where they are susceptible to checkpoint inhibitors such as caffeine and UCN-01. Caffeine 152-160 P53 Homo sapiens 27-30 23913470-6 2013 Conversely, acetylation of p53 is activating when class III deacetylases (DACs), or sirtuins, are inhibited by niacinamide.

Cyclophosphamide 29-45 P53 Homo sapiens 202-205 23582784-10 2013 We also observed that decitabine strongly induced G2/M arrest associated with p21 induction in both p53 allele-null (-/-) HCT116 and wild type p53 (+/+) HCT116 cell lines. Decitabine 22-32 P53 Homo sapiens 100-103 23582784-10 2013 We also observed that decitabine strongly induced G2/M arrest associated with p21 induction in both p53 allele-null (-/-) HCT116 and wild type p53 (+/+) HCT116 cell lines. Decitabine 22-32 P53 Homo sapiens 143-146 23648290-7 2013 Exposure of MM cells to [Gem+Clo] also decreased the level of ribosomal RNA (rRNA), which might have resulted in nucleolar stress, as reported previously, and caused a p53-dependent cell death. gemcitabine 25-28 P53 Homo sapiens 168-171 23376231-6 2013 Using 3D organotypic culture and other assays, we report that the stroma containing p53-deficient fibroblasts could induce the nontumorigenic epithelial cells of oral and ovarian tissue origins to become invasive through reactive nitrogen species (RNS)-mediated release of the cytokine ICAM1. Reactive Nitrogen Species 221-246 P53 Homo sapiens 84-87 23648290-8 2013 A reduction by approximately 50% in the cytotoxicity of Gem and Clo was observed in the presence of pifithrin alpha, a p53 inhibitor. gemcitabine 56-59 P53 Homo sapiens 119-122 12457968-9 2002 p21/Waf1, RNase L and p53 are known to have the PEST (proline-glutamic acid-serine-threonine) motif with relatively high scores in their sequences and considered to be sensitive to intracellular degradation. proline-glutamic acid-serine-threonine 54-92 P53 Homo sapiens 22-25 23998584-2 2013 Apoptosis of HL-60 cells was detected by flow cytometry, the expression of P21, P27 and P53 proteins in HL-60 cells treated with MG132 was assayed by Western blot. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 129-134 P53 Homo sapiens 88-91 23856246-5 2013 Furthermore, we identify pharmacogenomic correlations between specific variants in genes such as TP53, BRAF, ERBBs, and ATAD5 and anticancer agents such as nutlin, vemurafenib, erlotinib, and bleomycin showing one of many ways the data could be used to validate and generate novel hypotheses for further investigation. Erlotinib Hydrochloride 177-186 P53 Homo sapiens 97-101 23376231-6 2013 Using 3D organotypic culture and other assays, we report that the stroma containing p53-deficient fibroblasts could induce the nontumorigenic epithelial cells of oral and ovarian tissue origins to become invasive through reactive nitrogen species (RNS)-mediated release of the cytokine ICAM1. Reactive Nitrogen Species 248-251 P53 Homo sapiens 84-87 23376231-7 2013 The p53-deficient fibroblasts have increased RNS production and accumulation of oxidative DNA-damage products associated with specific upregulation of endothelial nitric oxide synthase (eNOS). Reactive Nitrogen Species 45-48 P53 Homo sapiens 4-7 23376231-9 2013 Our study uncovers the novel mechanism by which redox alteration associated with loss of p53 in stromal fibroblasts functions as a key inducer of epithelial transformation and invasion via RNS-mediated ICAM1 signaling. Reactive Nitrogen Species 189-192 P53 Homo sapiens 89-92 23540934-3 2013 In this work, using yeast-based assays, it was shown that both xanthones are potential inhibitors of the p53-MDM2 interaction. Xanthones 63-72 P53 Homo sapiens 105-108 23869206-10 2013 Finally, as an example of a novel design application, we describe the automated design of an oligooxopiperazine that inhibits the p53-MDM2 protein-protein interaction. oligooxopiperazine 93-111 P53 Homo sapiens 130-133 12221076-4 2002 With the loss of the p53 gene, the levels of phosphorylation of Ser-63 of c-Jun and Thr-183/Tyr-185 of JNK1/2 in p53-/- cells did not increase as markedly as in p53+/+ cells in response to a 1-h treatment with nocodazole or other microtubule-disrupting drugs such as vinblastine and colchicine. Colchicine 283-293 P53 Homo sapiens 21-24 12221076-4 2002 With the loss of the p53 gene, the levels of phosphorylation of Ser-63 of c-Jun and Thr-183/Tyr-185 of JNK1/2 in p53-/- cells did not increase as markedly as in p53+/+ cells in response to a 1-h treatment with nocodazole or other microtubule-disrupting drugs such as vinblastine and colchicine. Colchicine 283-293 P53 Homo sapiens 113-116 23593342-5 2013 In the absence of CSK, fulvestrant-induced proteasomal degradation of ERalpha protein was suppressed in both MCF-7 and T47D estrogen-dependent breast cancer cells whereas the TP53-mutated T47D cells were resistant to the cytocidal action of fulvestrant in the presence or absence of CSK. Fulvestrant 23-34 P53 Homo sapiens 175-179 12221076-4 2002 With the loss of the p53 gene, the levels of phosphorylation of Ser-63 of c-Jun and Thr-183/Tyr-185 of JNK1/2 in p53-/- cells did not increase as markedly as in p53+/+ cells in response to a 1-h treatment with nocodazole or other microtubule-disrupting drugs such as vinblastine and colchicine. Colchicine 283-293 P53 Homo sapiens 113-116 23579097-8 2013 Taken together, our results provide evidence that BLU can effectively regulate the pro-apoptotic and anti-angiogenic activity of gemcitabine through the direct interaction with vascular endothelial growth factor receptor-2, as well as the up-regulation of p21 and p53 expression. gemcitabine 129-140 P53 Homo sapiens 264-267 12171899-3 2002 Recently it was reported that triptolide (PG490), a purified compound from Tripterygium, possessed antitumor properties and induced apoptosis by p53-independent mechanisms in a variety of malignant cell lines. triptolide 30-40 P53 Homo sapiens 145-148 23373735-0 2013 Regulation of carboxylesterase-2 expression by p53 family proteins and enhanced anti-cancer activities among 5-fluorouracil, irinotecan and doxazolidine prodrug. doxazolidine 140-152 P53 Homo sapiens 47-50 12171899-3 2002 Recently it was reported that triptolide (PG490), a purified compound from Tripterygium, possessed antitumor properties and induced apoptosis by p53-independent mechanisms in a variety of malignant cell lines. triptolide 42-47 P53 Homo sapiens 145-148 23364678-0 2013 Poly(beta-amino ester) nanoparticle delivery of TP53 has activity against small cell lung cancer in vitro and in vivo. poly(beta-amino ester) 0-22 P53 Homo sapiens 48-52 23500768-5 2013 Compared with the control group, the astaxanthin-treated groups exhibited downregulated protein expressions of alpha-smooth muscle actin, vimentin, hydroxyproline, and B cell lymphoma/leukemia-2 as well as upregulated protein expressions of E-cadherin and p53 in vitro and in vivo. astaxanthine 37-48 P53 Homo sapiens 256-259 12171899-9 2002 Higher concentrations of triptolide induced apoptosis that was unexpectedly associated with nuclear accumulation of p53. triptolide 25-35 P53 Homo sapiens 116-119 12171899-11 2002 Our preclinical studies suggest that triptolide might be an effective preventive as well as therapeutic agent against prostate cancer and that triptolide may activate a functional p53 pathway in prostate cells. triptolide 143-153 P53 Homo sapiens 180-183 12716463-4 2002 To analyze the mechanism of p53 accumulation by E2, the stability of p53, ERalpha and MDM2 proteins was analyzed in the presence of cycloheximide under an E2-supplemented or -depleted condition. Cycloheximide 132-145 P53 Homo sapiens 69-72 23635777-7 2013 The addition of SAHA to Btz treatment was synergistic, as SAHA induced early acetylation of p53 and reduced interaction with its negative regulator MDM2, augmenting the effects of Btz. Vorinostat 16-20 P53 Homo sapiens 92-95 23635777-7 2013 The addition of SAHA to Btz treatment was synergistic, as SAHA induced early acetylation of p53 and reduced interaction with its negative regulator MDM2, augmenting the effects of Btz. Vorinostat 58-62 P53 Homo sapiens 92-95 23446751-11 2013 Immunohistochemical analysis showed p53 to be expressed significantly more frequently in IES (29 %) than in BilIN-3 (8 %). Yttrium 89-92 P53 Homo sapiens 36-39 23492773-10 2013 Pretreatment with PUMA and Bak siRNAs abolished miR-128-induced apoptosis in HCT116 p53+/+ and HCT116 p53-/- cells. mir-128 48-55 P53 Homo sapiens 84-87 23492773-10 2013 Pretreatment with PUMA and Bak siRNAs abolished miR-128-induced apoptosis in HCT116 p53+/+ and HCT116 p53-/- cells. mir-128 48-55 P53 Homo sapiens 102-105 23492773-11 2013 Taken together, we present the first evidence of miR-128 to be a new component joining the p53 network. mir-128 49-56 P53 Homo sapiens 91-94 23492773-12 2013 This study emphasizes that miR-128 is a novel mitochondria-targeted miRNA that can be further evaluated as a chemotherapeutic agent for human cancers as it induces apoptosis irrespective of p53 status. mir-128 27-34 P53 Homo sapiens 190-193 25337543-9 2013 Urushiol induced cytostatic cell growth inhibition via upregulation of the cyclin-dependent kinase inhibitors, p21 (WAF1/CIP1) and p27 (KIP1) proteins and down-regulation of cyclin-dependent kinase 2 and 4 proteins in a p53-independent manner. urushiol 0-8 P53 Homo sapiens 220-223 12492119-6 2002 PKC activator phorbol 12, 13-dibutyrate attenuated constitutive p53 levels in both HeLa and HeLa/CP cells. Phorbol 12,13-Dibutyrate 14-39 P53 Homo sapiens 64-67 23536721-2 2013 MK-8776 synergistically potentiated vorinostat-mediated apoptosis in various p53-wt or -deficient leukemia cell lines, whereas p53 knockdown by short hairpin RNA (shRNA) sensitized p53-wt cells to lethality of this regimen. Vorinostat 36-46 P53 Homo sapiens 77-80 23433851-0 2013 Arginine homozygosity in codon 72 of p53 correlates with failure to imatinib response in chronic myeloid leukemia. Imatinib Mesylate 68-76 P53 Homo sapiens 37-40 23433851-1 2013 PURPOSE: In this study, the role of the polymorphism at codon 72 of tumor protein p53 gene (TP53) was investigated regarding the response to treatment with imatinib in chronic myeloid leukemia (CML). Imatinib Mesylate 156-164 P53 Homo sapiens 82-85 12107653-11 2002 Increase of p53 protein was associated with wogonin- and fisetin-induced apoptosis; however, a p53-controlled gene, p21(Waf/Cip-1), was only induced in wogonin- (not fisetin-) treated SK-HEP-1 cells. fisetin 57-64 P53 Homo sapiens 12-15 23433851-1 2013 PURPOSE: In this study, the role of the polymorphism at codon 72 of tumor protein p53 gene (TP53) was investigated regarding the response to treatment with imatinib in chronic myeloid leukemia (CML). Imatinib Mesylate 156-164 P53 Homo sapiens 92-96 23433851-10 2013 CONCLUSION: The findings suggest that in CML patients, TP53 codon 72 polymorphism may contribute to a high Sokal score and failure to imatinib treatment. Imatinib Mesylate 134-142 P53 Homo sapiens 55-59 23455468-2 2013 Some genotoxic stresses are able to induce p53-dependent ceramide accumulation leading to cell death. Ceramides 57-65 P53 Homo sapiens 43-46 22665057-4 2013 Centriole overduplication assays in aphidicolin-arrested p53-deficient U2OS cells, in which the cell and the centrosome cycles are uncoupled, revealed that the effects of RhoD and its mutants on centrosome duplication and cell cycle are independent. Aphidicolin 36-47 P53 Homo sapiens 57-60 23471649-4 2013 Because Rb inactivation primes cells for apoptosis by p53-independent induction of procaspases, we postulated that alphaB-crystallin, an inhibitor of procaspase-3 activation, would suppress caspase activation in cells with combined Rb and p53 inactivation. alphab-crystallin 115-132 P53 Homo sapiens 54-57 23471649-4 2013 Because Rb inactivation primes cells for apoptosis by p53-independent induction of procaspases, we postulated that alphaB-crystallin, an inhibitor of procaspase-3 activation, would suppress caspase activation in cells with combined Rb and p53 inactivation. alphab-crystallin 115-132 P53 Homo sapiens 239-242 23471649-10 2013 Our results indicate that alphaB-crystallin inhibits caspase activation in cells primed for apoptosis by Rb inactivation and plays a novel oncogenic role in the context of combined Rb and p53 inactivation. alphab-crystallin 26-43 P53 Homo sapiens 188-191 23455468-6 2013 Furthermore, after highlighting the role and mechanism of action of p53 in apoptosis, we review the association of ceramide and p53 with respect to apoptosis. Ceramides 115-123 P53 Homo sapiens 128-131 23455468-7 2013 Strikingly, the hypothesis for a direct interaction between ceramide and p53 is less favored. Ceramides 60-68 P53 Homo sapiens 73-76 12067251-8 2002 Treatment of p53 cDNA with micromolar concentrations of (+/-)-anti-7,8-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene, (anti-BPDE, an ultimate carcinogen) or sub-micromolar concentrations of BP-7,8-dione in the presence of redox-cycling conditions (NADPH and CuCl(2)) also caused p53 mutations in a dose-dependent manner. cupric chloride 278-285 P53 Homo sapiens 13-16 23455468-8 2013 Recent data suggest that ceramide can act either upstream or downstream of p53 protein through posttranscriptional regulation or through many potential mediators, respectively. Ceramides 25-33 P53 Homo sapiens 75-78 23450781-9 2013 In contrast, sulphacetamide treatment lowered expression of p53/DRAM pathway in parallel with upregulation of Akt/mTOR pathway promoting cytoprotective autophagy. Sulfacetamide 13-27 P53 Homo sapiens 60-63 11867746-7 2002 Inhibitors of heat shock protein 90 (hsp90), radicicol and geldanamycin, induced degradation of p53 and suppressed p53-induced apoptosis in normal thymocytes and myeloid leukemic cells. monorden 45-54 P53 Homo sapiens 96-99 11867746-7 2002 Inhibitors of heat shock protein 90 (hsp90), radicicol and geldanamycin, induced degradation of p53 and suppressed p53-induced apoptosis in normal thymocytes and myeloid leukemic cells. monorden 45-54 P53 Homo sapiens 115-118 23544166-5 2013 RESULTS: AZD7762 inhibited clonal proliferation in a panel of GBM cell lines and increased radiosensitivity in p53-mutated GBM cell lines to a greater extent compared to p53 wild-type cells. 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 9-16 P53 Homo sapiens 111-114 22525275-0 2013 Lenalidomide promotes p53 degradation by inhibiting MDM2 auto-ubiquitination in myelodysplastic syndrome with chromosome 5q deletion. Lenalidomide 0-12 P53 Homo sapiens 22-25 11859874-10 2002 A non-significant increased risk of breast cancer was observed in the highest exposure level of dieldrin and polychlorinated biphenyls among women who developed a tumor with mutant p53 (odds ratio (OR) = 3.53, 95% confidence interval (CI) = 0.79-15.79 and OR = 3.00, 95% CI = 0.66-13.62). Polychlorinated Biphenyls 109-134 P53 Homo sapiens 181-184 22525275-4 2013 More importantly, we show that lenalidomide (Len) acts to stabilize MDM2, thereby accelerating p53 degradation. Lenalidomide 31-43 P53 Homo sapiens 95-98 22525275-4 2013 More importantly, we show that lenalidomide (Len) acts to stabilize MDM2, thereby accelerating p53 degradation. Lenalidomide 45-48 P53 Homo sapiens 95-98 23079745-10 2013 Furthermore, treatment of HCC cells with 5-aza-2"-deoxycytidine or ectopic expression of wildtype but not mutated p53 restored miR-125a-5p and miR-125b expression and inhibited tumor cell growth, suggesting their regulation by promoter methylation and p53 activity. Decitabine 41-63 P53 Homo sapiens 252-255 11871818-7 2002 This cotransfection led to selective growth inhibition in the cotransfected p53-mutated cells mediated by ganciclovir, whereas a single transfection of pCALtkL caused nonselective growth inhibition in both cell lines following ganciclovir treatment. Ganciclovir 106-117 P53 Homo sapiens 76-79 23549458-11 2013 Likewise, the expressions of activating transcription factor NF-kappaB and p53 genes in the arsenic-treated HaCaT cells were significantly higher than that in non-treated cells. Arsenic 92-99 P53 Homo sapiens 75-78 11878895-10 2001 A partially purified fraction that elutes at 0.6 M KCl from phosphocellulose contains the activity that degrades p53 in a 3C(Pro)-dependent manner. Potassium Chloride 51-54 P53 Homo sapiens 113-116 23174854-11 2013 Finally, in arsenic-treated HaCaT cells and in BD, a significant increase of dysfunctional p53 was found, and this event correlated with the increase in expression of Aurora-A. Arsenic 12-19 P53 Homo sapiens 91-94 23201008-0 2013 Cytotoxicity of 5-Aza-2"-deoxycytidine against gastric cancer involves DNA damage in an ATM-P53 dependent signaling pathway and demethylation of P16(INK4A). Decitabine 16-38 P53 Homo sapiens 92-95 23290777-7 2013 Mechanistic studies indicate that uncoupling ceramide glycosylation can modulate gene expression, decreasing MDR1 through the cSrc/beta-catenin pathway and restoring p53 expression via RNA splicing. Ceramides 45-53 P53 Homo sapiens 166-169 11557753-0 2001 Inhibition of cell cycle progression by the novel cyclophilin ligand sanglifehrin A is mediated through the NFkappa B-dependent activation of p53. sanglifehrin A 69-83 P53 Homo sapiens 142-145 24319226-2 2013 For example, 5-azacytidine and decitabine produce remissions and better overall survival in MDS with high-risk chromosome abnormalities at a surprisingly high rate, consistent with experimental observations that noncytotoxic DNA methyltransferase depletion by 5-azacytidine/decitabine can trigger cell cycle exit independently of p53, thus circumventing a basis for resistance to apoptosis-based DNA-damaging therapy. Decitabine 31-41 P53 Homo sapiens 330-333 23520471-8 2013 Additionally, MK1775 significantly enhances the cytotoxic effect of gemcitabine in sarcoma cells lines with different p53 mutational status. gemcitabine 68-79 P53 Homo sapiens 118-121 22672779-8 2013 DensNU was strongly correlated to the percentage of p53-marked nuclei in the epidermis, and DensPSB with the HSCORE. densnu 0-6 P53 Homo sapiens 52-55 11557753-6 2001 We report that sanglifehrin A is capable of activating the tumor suppressor gene p53 at the transcription level, leading to up-regulation of p21 that then binds and inhibits the cylcinE-Cdk2 complex. sanglifehrin A 15-29 P53 Homo sapiens 81-84 23739596-5 2013 At the same time, GN, but not gamma-Sch, inhibited the phosphorylation of checkpoint proteins such as p53, structural maintenance of chromosomes 1, and checkpoint kinase 1 in UV-irradiated cells. schizandrin B 18-20 P53 Homo sapiens 102-105 22933333-9 2012 Our findings also suggest that sequencing of the TP53 gene should be included in the study of patients with del(5q) as a single abnormality or in complex karyotype before lenalidomide treatment. Lenalidomide 171-183 P53 Homo sapiens 49-53 11557753-7 2001 Further analysis of different elements in the p53 promoter showed that sanglifehrin A activates p53 transcription primarily through the activation of the transcription factor NFkappaB by activating IkappaB kinase in a manner that is similar to several genotoxic agents. sanglifehrin A 71-85 P53 Homo sapiens 46-49 11557753-7 2001 Further analysis of different elements in the p53 promoter showed that sanglifehrin A activates p53 transcription primarily through the activation of the transcription factor NFkappaB by activating IkappaB kinase in a manner that is similar to several genotoxic agents. sanglifehrin A 71-85 P53 Homo sapiens 96-99 11745415-2 2001 This process was supposed to involve the tumor suppressor gene p53 as it was described that p53 negative cells were more sensitive to checkpoint inhibition by caffeine than the wildtype phenotype. Caffeine 159-167 P53 Homo sapiens 63-66 23153533-2 2012 We found that the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1), commonly upregulated in human cancers due to loss of TP53, contributes to biosynthesis regulation in part by controlling intracellular levels of its substrate, 3-phosphoglycerate (3-PG), and product, 2-phosphoglycerate (2-PG). 3-phosphoglycerate 231-249 P53 Homo sapiens 124-128 22955915-1 2012 TP53 mutation is an independent marker of poor prognosis in patients with diffuse large B-cell lymphoma (DLBCL) treated with cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (CHOP) therapy. Cyclophosphamide 125-141 P53 Homo sapiens 0-4 23127292-0 2012 Prognostic interaction between expression of p53 and estrogen receptor in patients with node-negative breast cancer: results from IBCSG Trials VIII and IX. ibcsg 130-135 P53 Homo sapiens 45-48 23131146-4 2012 In contrast, while TP53 mutations have shown to predict response to cyclophosphamide high dose therapy, mutations in general have been associated with anthracycline resistance in human breast cancers. Cyclophosphamide 68-84 P53 Homo sapiens 19-23 23527225-0 2013 The anti-melanoma activity of dinaciclib, a cyclin-dependent kinase inhibitor, is dependent on p53 signaling. dinaciclib 30-40 P53 Homo sapiens 95-98 23527225-6 2013 Further mechanistic studies revealed that dinaciclib induces p53 expression whilst simultaneously downregulating the expression of the anti-apoptotic factors Mcl-1 and XIAP. dinaciclib 42-52 P53 Homo sapiens 61-64 23527225-8 2013 Knockdown of p53 completely abolished the induction of apoptosis seen following dinaciclib treatment as shown by a lack of annexin-V staining and caspase-3 cleavage. dinaciclib 80-90 P53 Homo sapiens 13-16 23527225-9 2013 Altogether, these data show that dinaciclib induces apoptosis in a large panel of melanoma cell lines through a mechanism requiring p53 expression. dinaciclib 33-43 P53 Homo sapiens 132-135 23010984-1 2012 An efficient electrochemical approach is developed for ultrasensitive profiling of the methylation status of the p53 tumor suppressor gene based on a label-free biosensor in combination with bisulfite conversion. hydrogen sulfite 191-200 P53 Homo sapiens 113-116 22973058-3 2012 Regardless of the breast cancer subtype tested or the p53 status of the cells, 8-NH(2)-Ado was more cytotoxic than either gemcitabine or etoposide. 8-nh(2)-ado 79-90 P53 Homo sapiens 54-57 11745415-2 2001 This process was supposed to involve the tumor suppressor gene p53 as it was described that p53 negative cells were more sensitive to checkpoint inhibition by caffeine than the wildtype phenotype. Caffeine 159-167 P53 Homo sapiens 92-95 11745415-11 2001 In addition, caffeine restored a G1 delay after irradiation in the cell lines with abrogated p53 functions. Caffeine 13-21 P53 Homo sapiens 93-96 11576999-9 2001 p53 null human lung cancer H1299 cells transfected with an ecdysone-inducible p53 exhibited equivalent sensitivity to tachpyridine in the presence and absence of p53, demonstrating the lack of requirement for p53 in an isogenic cell system. Ecdysone 59-67 P53 Homo sapiens 0-3 22991965-5 2012 The ordering of the N-terminus upon binding of the piperidinones extends the current model of MDM2-p53 interaction and provides a new route to rational design of superior inhibitors. 2-piperidone 51-64 P53 Homo sapiens 99-102 22575263-8 2012 These data point to wood dust exposure as the causal factor in the mutagenesis of TP53, possibly caused by reactive nitrogen species generated through a chronic inflammatory process.

Ecdysone 59-67 P53 Homo sapiens 78-81 11576999-9 2001 p53 null human lung cancer H1299 cells transfected with an ecdysone-inducible p53 exhibited equivalent sensitivity to tachpyridine in the presence and absence of p53, demonstrating the lack of requirement for p53 in an isogenic cell system. Ecdysone 59-67 P53 Homo sapiens 78-81 22843330-4 2012 Focused gene expression array analysis followed by immunoblot detection revealed that DP rapidly activates the cytotoxic unfolded protein response (UPR; involving phospho-PERK, phospho-eIF2alpha, Grp78, CHOP, and Hsp70) and the mitochondrial pathway of apoptosis with p53 upregulation and modulation of Bcl-2 family members (involving Noxa, Mcl-1, and Bcl-2). dp 86-88 P53 Homo sapiens 268-271 22825736-0 2012 The Chk1 inhibitor AZD7762 sensitises p53 mutant breast cancer cells to radiation in vitro and in vivo. 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 19-26 P53 Homo sapiens 38-41 22903553-12 2012 Taken together, these results provide evidence that sMEK1 can effectively regulate the pro-apoptotic activity of gemcitabine through the up-regulation of p53 expression. gemcitabine 113-124 P53 Homo sapiens 154-157 11576999-9 2001 p53 null human lung cancer H1299 cells transfected with an ecdysone-inducible p53 exhibited equivalent sensitivity to tachpyridine in the presence and absence of p53, demonstrating the lack of requirement for p53 in an isogenic cell system. Ecdysone 59-67 P53 Homo sapiens 78-81 22678742-4 2012 Here, we found that PQ significantly decreases cell viability, increases sub-G1 hypodiploids DNA contents and caspase 3/7 activity in lung alveolar epithelial cell-derived L2 cells, which also caused mitochondrial dysfunction, and decreased the mRNA expression of Bcl-2 and increased that of Bax, Bak, and p53. Primaquine 20-22 P53 Homo sapiens 306-309 22678742-10 2012 Cells transfected with Nrf-2 siRNA significantly reversed the PQ-induced toxicity, including depolarization of MMP, increased the Bax, Bak, p53 mRNAs expression, decreased the Bcl-2 mRNA expression, increased the caspase 3/7 activity, Grp78, CHOP, and caspase-12 mRNAs and protein expression, and decreased that of pro-caspase-3. Primaquine 62-64 P53 Homo sapiens 140-143 22825736-3 2012 In the present study, we aimed to demonstrate for the first time, that AZD7762 not only promotes radiation-induced apoptosis and mitotic catastrophe of p53 mutant T47D breast cancer cells in vitro, but also delays their xenograft growth in response to radiation in vivo. 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 71-78 P53 Homo sapiens 152-155 22825736-5 2012 These results suggest that AZD7762 may effectively abrogate radiation-induced G2/M arrest and inhibit radiation damage repair in conferring radiosensitivity on p53 mutant T47D breast cancer cells, by promoting radiation-induced apoptosis and mitotic catastrophe. 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 27-34 P53 Homo sapiens 160-163 11677656-8 2001 Interestingly, caffeine and other methyl xanthines preferentially radiosensitize cells that lack normal p53 function.

Lenalidomide 55-67 P53 Homo sapiens 129-132 22041920-11 2012 Among these changes, RT-PCR and Western blotting showed that expression of tumor protein 53-induced nuclear protein 1, a gene regulating cell death and DNA repair, was increased by gemcitabine treatment and substantially decreased by GSK3beta inhibition. gemcitabine 181-192 P53 Homo sapiens 75-91 11240376-0 2001 Deoxycholate induces DNA damage and apoptosis in human colon epithelial cells expressing either mutant or wild-type p53. Deoxycholic Acid 0-12 P53 Homo sapiens 116-119 20680659-4 2012 We found that nutlin-3 and HDACi cooperated to induce cell death in the p53 wild-type cell lines A549 and A2780, but not in the p53 null cell line PC-3, as assessed by Alamar Blue assay and flow cytometric analyses of propidium iodide uptake and mitochondrial depolarization. Propidium 218-234 P53 Homo sapiens 72-75 20680659-8 2012 We observed vorinostat to induce p53 hyperacetylation, to reduce the constitutive gene expression of MDM2 and MDM4, and to counteract the nutlin-3-induced upregulation of MDM2 gene expression.

Arsenic 89-96 P53 Homo sapiens 21-24 21982800-5 2011 RCC patients with the p53Arg/Arg genotype had a signicantly low percentage of inorganic arsenic, a low percentage of monomethylarsonic acid (MMA), and a high percentage of dimethylarsinic acid (DMA), which indicates efcient arsenic methylation capacity. Arsenic 88-95 P53 Homo sapiens 22-25 11544835-7 2001 Gluthoxim induction of cell death was demonstrated in both cell lines; however, apoptosis in cells C8 (with intact gene p53) was much more pronounced than in cells A4 without this gene. gluthoxim 0-9 P53 Homo sapiens 120-123 11090099-0 2000 Effect of saikosaponin, a triterpene saponin, on apoptosis in lymphocytes: association with c-myc, p53, and bcl-2 mRNA. saikosaponin D 10-22 P53 Homo sapiens 99-102 20499132-7 2011 Moreover, this effect was not restricted to cell lines as LQB-118 produced significant apoptosis rate in cells from CML patients exhibiting multifactorial drug resistance phenotype such as P-glycoprotein, MRP1 and p53 overexpression. LQB 118 58-65 P53 Homo sapiens 214-217 22130357-4 2012 Further, taurine promoted endothelial cell cycle progression to the S and G2/M phases by up-regulating the positive cell cycle proteins, particularly cyclins D1 and B, as well as down-regulating the negative cell cycle proteins, p53 and p21(WAF1/CIP1), resulting in Rb phosphorylation. Taurine 9-16 P53 Homo sapiens 229-232 11090099-21 2000 It is suggested that the apoptotic effect of saikosaponin-d may be partly mediated by increases in c-myc and p53 mRNA levels accompanied by a decrease in bcl-2 mRNA level. saikosaponin D 45-59 P53 Homo sapiens 109-112 21907236-0 2011 Fluazinam-induced apoptosis of SH-SY5Y cells is mediated by p53 and Bcl-2 family proteins. fluazinam 0-9 P53 Homo sapiens 60-63 23101268-4 2012 Pre-treatment with NU7026 resulted into decreased activation of checkpoint kinase-2 (Thr68), p53 (Ser15 and Ser392), and histone H2A.X (Ser139) 2 hours after irradiation. 2-(morpholin-4-yl)benzo(h)chromen-4-one 19-25 P53 Homo sapiens 93-96 11080661-0 2000 The effect of dibenzo[a,1]pyrene and benzo[a]pyrene on human diploid lung fibroblasts: the induction of DNA adducts, expression of p53 and p21(WAF1) proteins and cell cycle distribution. dibenzo[a,1]pyrene 14-32 P53 Homo sapiens 131-134 10922372-0 2000 Vanadate induces p53 transactivation through hydrogen peroxide and causes apoptosis. Vanadates 0-8 P53 Homo sapiens 17-20 22393286-7 2012 Both the mRNA and protein levels of tumor suppressor gene p53 and apoptotic gene bax were upregulated while the antiapoptotic gene bcl-2 was downregulated in ZnO NP-treated HepG2 cells. zno np 158-164 P53 Homo sapiens 58-61 21880715-7 2011 In addition, a unique EDEE motif between the loop of anti-parallel beta7 and beta8 sheets of the SET core not only interacts with p53 substrate but also forms a hydrogen bond network with residues from CTD. edee 22-26 P53 Homo sapiens 130-133 21880715-8 2011 These observations suggest that the tetratricopeptide repeat and EDEE motif may play an important role in determining p53 substrate binding specificity. edee 65-69 P53 Homo sapiens 118-121 10922372-3 2000 The present study investigated the vanadate-induced p53 activation and involvement of reactive oxygen species (ROS) in p53 activation as well as the role of p53 in apoptosis induction by vanadate. Vanadates 35-43 P53 Homo sapiens 52-55 21946324-8 2011 Pretreatment with the specific P38MAPK inhibitor SB203580 (5 mumol/L) significantly reduced CrTX-induced apoptosis and cleaved caspase-3 level, but G(1) arrest remained unchanged and highly expressed p53 sustained. SB 203580 49-57 P53 Homo sapiens 200-203 22429346-4 2012 Hypermethylation of the promoters of the p53-BAX mitochondrial apoptosis genes cyclin-dependent kinase inhibitor 2A (CDKN2A), death-associated protein kinase 1 (DAPK1) and PYD and CARD domain containing (PYCARD) was detected by methylation-specific polymerase chain reaction, with and without DAC treatment.

Ganciclovir 222-225 P53 Homo sapiens 260-263 10842159-6 2000 A similar reduction in cellular proliferation and upregulation of p21 expression were achieved with iNOS gene transfer as well as treatment with the NO-donor S-nitroso-N-acetylpenicillamine (SNAP), demonstrating the p53-independent nature of these NO-mediated pathways. S-Nitroso-N-Acetylpenicillamine 158-189 P53 Homo sapiens 216-219 20367642-4 2010 We thus hypothesized that various anticancer drugs such as p53-activating reagents and IFNs may potentiate poly I:C-induced tumor cell death through the up-regulation of TLR3 expression. Poly I-C 107-115 P53 Homo sapiens 59-62 20367642-6 2010 We found that the DNA-damaging reagent 5-fluorouracil (5-FU) increased TLR3 mRNA expression and potentiated poly I:C-induced apoptosis in HCT116 p53(+/+) cells but had only minimal effect in p53(-/-) cells, indicating a p53-dependent pathway. Poly I-C 108-116 P53 Homo sapiens 145-148 20367642-8 2010 Furthermore, the combination of poly I:C, 5-FU and IFN-alpha induced the highest apoptosis in HCT116 p53(+/+) and p53(-/-) cells. Poly I-C 32-40 P53 Homo sapiens 101-104 20367642-8 2010 Furthermore, the combination of poly I:C, 5-FU and IFN-alpha induced the highest apoptosis in HCT116 p53(+/+) and p53(-/-) cells. Poly I-C 32-40 P53 Homo sapiens 114-117 20367642-9 2010 Taken together, these data suggest that the anticancer drugs increased TLR3 expression and subsequently potentiated poly I:C-induced apoptosis likely via p53-dependent and -independent pathways. Poly I-C 116-124 P53 Homo sapiens 154-157 22031102-4 2011 Blockage of apoptosis by MG132 correlates with p53 stabilization and upregulation of p21/WAF1, a p53 transcriptional target. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 25-30 P53 Homo sapiens 47-50 22031102-4 2011 Blockage of apoptosis by MG132 correlates with p53 stabilization and upregulation of p21/WAF1, a p53 transcriptional target. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 25-30 P53 Homo sapiens 97-100 22033280-7 2011 Authentic nuclear proteins such as PCNA, p53 and LAP2a were found both in the light and the heavy sucrose fractions together with lamin A.

Cyclophosphamide 125-141 P53 Homo sapiens 29-33 10737712-1 2000 Recently, it has been shown that 9-hydroxyellipticine (9-HE), an antitumor alkaloid has a unique property of restoring functional wild-type (wt) p53 activity via inhibition of mutant (mt) p53 protein phosphorylation. 9-hydroxyellipticine 33-53 P53 Homo sapiens 145-148 21693655-3 2011 PATIENTS AND METHODS: Epithelial p53 expression was evaluated using two immunohistochemical antibodies (DO7 and 1801) in formalin-fixed, paraffin-embedded tissue from patients with node-positive breast cancer who were randomized to four cycles of cyclophosphamide and one of three doses of doxorubicin (60, 75, or 90 mg/m(2); AC) and to receive four subsequent cycles of paclitaxel (T) or not. Cyclophosphamide 247-263 P53 Homo sapiens 33-36 19757179-0 2010 beta-Ionone-induced apoptosis in human osteosarcoma (U2os) cells occurs via a p53-dependent signaling pathway. beta-ionone 0-11 P53 Homo sapiens 78-81 10737712-1 2000 Recently, it has been shown that 9-hydroxyellipticine (9-HE), an antitumor alkaloid has a unique property of restoring functional wild-type (wt) p53 activity via inhibition of mutant (mt) p53 protein phosphorylation. 9-hydroxyellipticine 33-53 P53 Homo sapiens 188-191 19757179-6 2010 Furthermore, Expression of the p53 protein increased in a concentration-dependent and time-dependent manner according to immunocytochemistry and immunoblotting after beta-ionone treatment. beta-ionone 166-177 P53 Homo sapiens 31-34 19757179-8 2010 In summary, these data suggested that beta-ionone induced apoptosis in a concentration-dependent manner in U2os cells via a p53-dependent mitochondrial pathway. beta-ionone 38-49 P53 Homo sapiens 124-127 10737712-1 2000 Recently, it has been shown that 9-hydroxyellipticine (9-HE), an antitumor alkaloid has a unique property of restoring functional wild-type (wt) p53 activity via inhibition of mutant (mt) p53 protein phosphorylation. 9-hydroxyellipticine 55-59 P53 Homo sapiens 145-148 21725200-3 2011 We report that the primary molecular mechanism of decitabine-depletion of DNA methyltransferase-1 following its "suicide" inactivation-is not absolutely associated with cell cycle progression in HCT 116 colon cancer cells, but is associated with their p53 genotype. Decitabine 50-60 P53 Homo sapiens 252-255 21725200-5 2011 Secondary changes in CpG methylation occurred only in growing cells ~24-48 h after decitabine treatment; these epigenetic changes coincided with p53 accumulation, an index of DNA damage. Decitabine 83-93 P53 Homo sapiens 145-148 10737712-1 2000 Recently, it has been shown that 9-hydroxyellipticine (9-HE), an antitumor alkaloid has a unique property of restoring functional wild-type (wt) p53 activity via inhibition of mutant (mt) p53 protein phosphorylation. 9-hydroxyellipticine 55-59 P53 Homo sapiens 188-191 10737712-3 2000 Exposure of cells to 9-HE at a relatively low concentration of 1 microM induced almost no cell death but was sufficient to restore wt p53 activity, as evidenced by an induction of endogenous p21WAF1/CIP1 concomitant with G1 and G2/M arrests in cell-cycle progression. 9-hydroxyellipticine 21-25 P53 Homo sapiens 134-137 20587660-0 2010 p53-independent induction of G1 arrest and p21WAF1/CIP1 expression by ascofuranone, an isoprenoid antibiotic, through downregulation of c-Myc. ascofuranone 70-82 P53 Homo sapiens 0-3 10737712-6 2000 These effects of 9-HE were specific for several cell lines containing mt p53 and were not observed in p53-negative or wt p53 expressing cells. 9-hydroxyellipticine 17-21 P53 Homo sapiens 73-76 20587660-2 2010 Here, we study the effects of ascofuranone on cell cycle progression in human cancer cells and find that ascofuranone induces G(1) arrest without cytoxicity with upregulation of p53 and p21(WAF1/CIP1) while downregulating c-Myc and G(1) cyclins. ascofuranone 105-117 P53 Homo sapiens 178-181 21565980-0 2011 Nicotinamide blocks proliferation and induces apoptosis of chronic lymphocytic leukemia cells through activation of the p53/miR-34a/SIRT1 tumor suppressor network. Niacinamide 0-12 P53 Homo sapiens 120-123 20587660-3 2010 Chromatin immunoprecipitation assay and RNA interference studies with cells deficient in p53 and p21 show that ascofuranone induces p21(WAF1/CIP1) expression and subsequent G(1) arrest through the release of p21(WAF1/CIP1) promoter from c-Myc-mediated transcriptional repression, independent of p53. ascofuranone 111-123 P53 Homo sapiens 89-92 10634797-6 2000 The increased expression of p21 mRNA or p53 activation during late G(1) or S phase was also caused by addition of 8-bromo-cGMP and effectively blocked by a specific inhibitor of the soluble guanylate cyclase. 8-bromocyclic GMP 114-126 P53 Homo sapiens 40-43 20587660-3 2010 Chromatin immunoprecipitation assay and RNA interference studies with cells deficient in p53 and p21 show that ascofuranone induces p21(WAF1/CIP1) expression and subsequent G(1) arrest through the release of p21(WAF1/CIP1) promoter from c-Myc-mediated transcriptional repression, independent of p53. ascofuranone 111-123 P53 Homo sapiens 295-298 21565980-6 2011 Nicotinamide modulates the p53-dependent genes p21, NOXA, BAX, and Mcl-1, indicating an activation of the p53 pathway and of caspase-3. Niacinamide 0-12 P53 Homo sapiens 27-30 21565980-6 2011 Nicotinamide modulates the p53-dependent genes p21, NOXA, BAX, and Mcl-1, indicating an activation of the p53 pathway and of caspase-3. Niacinamide 0-12 P53 Homo sapiens 106-109 21565980-11 2011 We therefore concluded that nicotinamide has the dual property of inhibiting SIRT1 through a noncompetitive enzymatic block (p53 independent) and at the same time through miR-34a induction (p53 dependent). Niacinamide 28-40 P53 Homo sapiens 125-128 21565980-11 2011 We therefore concluded that nicotinamide has the dual property of inhibiting SIRT1 through a noncompetitive enzymatic block (p53 independent) and at the same time through miR-34a induction (p53 dependent). Niacinamide 28-40 P53 Homo sapiens 190-193 21565980-12 2011 These observations suggested the therapeutic potential of nicotinamide, a novel, safe, and inexpensive drug, to be used in addition to chemotherapy for CLL patients with wt p53. Niacinamide 58-70 P53 Homo sapiens 173-176 21550660-3 2011 Another class of anti-epigenetic agent histone deacetylase inhibitor (HDACI) inhibited the proliferation of both MV4-11 and MV4-11 TP53 R248W cells. mv4-11 124-130 P53 Homo sapiens 131-135 21550660-4 2011 Notably, when 5-AzadC was combined with HDACI MS-275, apoptosis in MV4-11 TP53 R248W cells was significantly enhanced in parallel with activation of the caspase cascade, up-regulation of p21waf1 and gamma-H2AX, and down-regulation of Mcl-1. Decitabine 14-21 P53 Homo sapiens 74-78 21550660-5 2011 Interestingly, inhibition of caspase 3 by the pan-caspase inhibitor attenuated the combination of 5-AzadC and MS-275-mediated apoptosis and down-regulation of Mcl-1 in MV4-11 TP53 R248W cells. Decitabine 98-105 P53 Homo sapiens 175-179 20133503-3 2010 By using pairs of isogenic colon cancer cell lines that differ only in p53 expression (RKO and HCT116), securinine was found to exhibit these properties. securinine 104-114 P53 Homo sapiens 71-74 20133503-4 2010 Securinine (30 microM) induces apoptosis in 73% of p53-null HCT116 cells (LD(50) 17.5 microM) as opposed to 17.6% of HCT116 parental cells (LD(50) 50 microM) at 72 h after treatment. securinine 0-10 P53 Homo sapiens 51-54 20133503-5 2010 The mechanism of securinine-mediated death in p53-deficient cells involves the induction of the p53 family member, p73. securinine 17-27 P53 Homo sapiens 46-49 20133503-5 2010 The mechanism of securinine-mediated death in p53-deficient cells involves the induction of the p53 family member, p73. securinine 17-27 P53 Homo sapiens 96-99 21550660-8 2011 Combination of 5-AzadC and MS-275 may be a promising treatment strategy for individuals with leukemia in which TP53 is inactivated. Decitabine 15-22 P53 Homo sapiens 111-115 11322510-4 2000 We also report on the permissive effects of Vitamin D3 and the Vitamin D3 analog EB 1089 in the promotion of apoptosis in p53-wild-type cells. Cholecalciferol 44-54 P53 Homo sapiens 122-125 21550362-0 2011 Metabolites of arsenic and increased DNA damage of p53 gene in arsenic plant workers. Arsenic 63-70 P53 Homo sapiens 51-54 21550362-6 2011 Those findings suggested that DNA damage of exon 5 and 8 of p53 gene existed in the population occupationally exposed to arsenic. Arsenic 121-128 P53 Homo sapiens 60-63 20480521-13 2010 However, gemcitabine and dicoumarol combination induced increased p53 and decreased Bcl-(XL) levels in KKU-100, but not in KKU-M214 cells. gemcitabine 9-20 P53 Homo sapiens 66-69 20171273-5 2010 By the use of either small interfering RNAs to target SIRT1 or the SIRT1 inhibitor nicotinamide we found that Nox1-dependent inhibition of p53 transcriptional activity was SIRT1-dependent. Niacinamide 83-95 P53 Homo sapiens 139-142 11322510-4 2000 We also report on the permissive effects of Vitamin D3 and the Vitamin D3 analog EB 1089 in the promotion of apoptosis in p53-wild-type cells. Cholecalciferol 63-73 P53 Homo sapiens 122-125 21502403-7 2011 The p53 tumor suppressor was stabilized by an increased acetylation in response to vorinostat and a reduced Ser315 phosphorylation in response to aurora kinase A. Vorinostat 83-93 P53 Homo sapiens 4-7 10534768-1 1999 We applied the differential mRNA display method to isolate genes regulated by wild-type TP53 in cells of a colon-cancer line (SW480) in which we had established an inducible TP53 expression system under the control of the lactose operon.

Carboplatin 0-11 P53 Homo sapiens 175-178 21377279-9 2011 Although radiosensitization was observed in both p53 wild-type and p53-deficient cells, p53 status might influence induction of apoptosis after gemcitabine/radiation treatment, whereas no effect on cell cycle progression was noticed. gemcitabine 144-155 P53 Homo sapiens 67-70 20332106-5 2010 When cells were treated with the proteasome inhibitor MG132, the size and frequency of p53-containing nucleolar cavities increased, and the protein partially colocalized with inactivated proteasomes. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 54-59 P53 Homo sapiens 87-90 10534768-1 1999 We applied the differential mRNA display method to isolate genes regulated by wild-type TP53 in cells of a colon-cancer line (SW480) in which we had established an inducible TP53 expression system under the control of the lactose operon.

Arsenic 34-41 P53 Homo sapiens 7-10 21454520-0 2011 Mutant p53 protein is targeted by arsenic for degradation and plays a role in arsenic-mediated growth suppression. Arsenic 78-85 P53 Homo sapiens 7-10 21454520-4 2011 Interestingly, wild type p53 is accumulated in cells treated with arsenic compounds, presumably due to arsenic-induced oxidative stresses. Arsenic 66-73 P53 Homo sapiens 25-28 21454520-4 2011 Interestingly, wild type p53 is accumulated in cells treated with arsenic compounds, presumably due to arsenic-induced oxidative stresses. Arsenic 103-110 P53 Homo sapiens 25-28 21454520-6 2011 In contrast, we found that arsenic compounds degrade both endogenous and ectopically expressed mutant p53 in time- and dose-dependent manners. Arsenic 27-34 P53 Homo sapiens 102-105 21454520-7 2011 We also found that arsenic trioxide decreases the stability of mutant p53 protein through a proteasomal pathway, and blockage of mutant p53 nuclear export can alleviate the arsenic-induced mutant p53 degradation. Arsenic 19-26 P53 Homo sapiens 70-73 20233881-6 2010 RESULTS: AZD7762 treatment enhanced the radiosensitivity of p53-mutated tumor cell lines (DMFs ranging from 1.6-1.7) to a greater extent than for p53 wild-type tumor lines (DMFs ranging from 1.1-1.2). 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 9-16 P53 Homo sapiens 60-63 20233881-10 2010 CONCLUSIONS: AZD7762 effectively enhanced the radiosensitivity of mutated p53 tumor cell lines and HT29 xenografts and was without untoward toxicity when administered alone or in combination with radiation. 3-(carbamoylamino)-5-(3-fluorophenyl)-N-(3-piperidyl)thiophene-2-carboxamide 13-20 P53 Homo sapiens 74-77 21454520-9 2011 Taken together, we found that mutant p53 is a target of arsenic compounds, which provides an insight into exploring arsenic compound-based therapy for tumors harboring a mutant p53.

Arsenic 116-123 P53 Homo sapiens 37-40 21454520-9 2011 Taken together, we found that mutant p53 is a target of arsenic compounds, which provides an insight into exploring arsenic compound-based therapy for tumors harboring a mutant p53. Arsenic 116-123 P53 Homo sapiens 177-180 20123963-3 2010 To elucidate the direct phosphorylation of p53 at Ser46 by ATM, an ATM mutant (ATM-AS) sensitive to ATP analogues was engineered. Arsenic 83-85 P53 Homo sapiens 43-46 10397271-7 1999 In addition, the accumulation of hsp72 and p53 in the wtp53 cells was induced by the administration of an nitric oxide-generating agent, S-nitroso-N-acetylpenicillamine, to the medium. S-Nitroso-N-Acetylpenicillamine 137-168 P53 Homo sapiens 43-46 21123063-0 2011 Improvement of the synthesis and pharmacokinetic properties of chromenotriazolopyrimidine MDM2-p53 protein-protein inhibitors. chromenotriazolopyrimidine 63-89 P53 Homo sapiens 95-98 20334641-3 2010 However, amifostine has also been described as a potent hypoxia-mimetic compound and as a strong p53 inducer; both effects are known to potently modulate vascular endothelial growth factor (VEGF-A) expression. Amifostine 9-19 P53 Homo sapiens 97-100 21123063-2 2011 We report several optimizations to the synthesis of the chromenotriazolopyrimidine series of MDM2-p53 protein-protein interaction inhibitors. chromenotriazolopyrimidine 56-82 P53 Homo sapiens 98-101 10384915-6 1999 Exposure to PUVA induced an increase in p53 expression in non-lesional skin in 14/19 patients, putatively as a response to DNA damage caused by PUVA. puva 12-16 P53 Homo sapiens 40-43 21472523-3 2011 Using a combination of top-down and middle-down FTICR mass spectrometry, we show that of the 10 Cys residues in the core domain of wild-type p53, Cys182 and Cys277 exhibit a remarkable preference for modification by the alkylating reagent N-ethylmaleimide. Ethylmaleimide 239-255 P53 Homo sapiens 141-144 21241062-6 2011 2,2-Diphenylethyl ITC, a synthetic ITC, is one of the most potent depletors of mutant p53 studies and induces apoptosis to the greatest extent in mutant p53 breast cancer cells. 2,2-diphenylethyl itc 0-21 P53 Homo sapiens 86-89 21241062-6 2011 2,2-Diphenylethyl ITC, a synthetic ITC, is one of the most potent depletors of mutant p53 studies and induces apoptosis to the greatest extent in mutant p53 breast cancer cells. 2,2-diphenylethyl itc 0-21 P53 Homo sapiens 153-156 20036271-0 2010 Arsenite induced poly(ADP-ribosyl)ation of tumor suppressor P53 in human skin keratinocytes as a possible mechanism for carcinogenesis associated with arsenic exposure. Arsenic 151-158 P53 Homo sapiens 60-63 20025073-2 2010 The aim of this study was to explore the effect of dietary folate and vitamin B(6) intake on p53 in the molecular pathogenesis of esophageal adenocarcinoma (EADC). Niacinamide 70-79 P53 Homo sapiens 93-96 10384915-6 1999 Exposure to PUVA induced an increase in p53 expression in non-lesional skin in 14/19 patients, putatively as a response to DNA damage caused by PUVA. puva 144-148 P53 Homo sapiens 40-43 21194611-2 2011 Previous studies have demonstrated that arsenic and chromium complexes are able to activate p53, but there is a dearth of data investigating whether uranium complexes exhibit similar effects.

N-acetylsphingosine 47-58 P53 Homo sapiens 91-94 21224072-4 2011 We found that well-known proteasome inhibitors such as MG132 and bortezomib, as well as the recently discovered proteasome inhibitor thiostrepton, induced p53-independent apoptosis in human cancer cell lines that correlated with p53-independent induction of proapoptotic Noxa but not Puma protein. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 55-60 P53 Homo sapiens 155-158 20081368-7 2010 Detailed sequence analysis shows the exceptional retention of key features of both proteins from man to Placazoan implying that the p53-Mdm2 interaction and its regulation have been conserved from a basal eumetazoan since the pre-cambrian era over 1 billion years ago. eumetazoan 205-215 P53 Homo sapiens 132-135 20013323-3 2010 MV4-11 TP53 R248W cells were relatively resistant to AZD1152-HQPA-mediated growth arrest, as measured by MTT and clonogenic assays. monooxyethylene trimethylolpropane tristearate 105-108 P53 Homo sapiens 7-11 10360645-7 1999 FACS-analysis revealed that C2-ceramide induced massive p53-dependent apoptosis (40-50% after 12-24 h) and cell cycle analysis showed a transient G1 arrest in p53-deficient tumour cells 12-24 h after C2-ceramide exposure. N-acetylsphingosine 28-39 P53 Homo sapiens 56-59 21224072-4 2011 We found that well-known proteasome inhibitors such as MG132 and bortezomib, as well as the recently discovered proteasome inhibitor thiostrepton, induced p53-independent apoptosis in human cancer cell lines that correlated with p53-independent induction of proapoptotic Noxa but not Puma protein. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 55-60 P53 Homo sapiens 229-232 10100719-0 1999 Expression of p53 in cisplatin-resistant ovarian cancer cell lines: modulation with the novel platinum analogue (1R, 2R-diaminocyclohexane)(trans-diacetato)(dichloro)-platinum(IV). dichloro)-platinum 157-175 P53 Homo sapiens 14-17 19857530-6 2010 CBB-detectable ubiquitinated p53 was easily purified from the insect cell-free protein synthesis system, allowing analysis of the Ub-conjugated proteins by mass spectrometry (MS). coomassie Brilliant Blue 0-3 P53 Homo sapiens 29-32 9888876-9 1999 ANP, NOR3, and 8-bromo-cGMP caused marked accumulations of the tumor suppressor gene product p53 but not of bcl-2, as determined by Western blot analysis. 8-bromocyclic GMP 15-27 P53 Homo sapiens 93-96 19998502-7 2009 MTT assay showed that the growth of HepG2 cells was mucj more significantly inhibited by LV-NT4(Si)-p53(N15)-Ant than by LV-EGFP. monooxyethylene trimethylolpropane tristearate 0-3 P53 Homo sapiens 100-103 19998502-11 2009 LDH release from HepG2 cells was analyzed at 24, 48, 72 and 96 h after infection with LV-NT4(Si)-p53(N15)-Ant and LV-EGFP, which showed that LDH release was significantly higher in LV-NT4(Si)-p53(N15)-Ant treatment group (682 IU/L) than in control group (45 IU/L, P < 0.01).

Lovastatin 21-31 P53 Homo sapiens 85-88 20923768-7 2010 We report that endocannabinoids stabilize lysosomes by preventing the Abeta-induced up-regulation of the tumor suppressor protein, p53, and its interaction with the lysosomal membrane. Endocannabinoids 15-31 P53 Homo sapiens 131-134 21159612-3 2010 The combination of vorinostat and flavopiridol was synergistic and significantly more cytotoxic (P < 0.001) in cell lines with p53-LOF and in the clones stably transfected with dominant-negative p53 plasmids. Vorinostat 19-29 P53 Homo sapiens 130-133 21159612-3 2010 The combination of vorinostat and flavopiridol was synergistic and significantly more cytotoxic (P < 0.001) in cell lines with p53-LOF and in the clones stably transfected with dominant-negative p53 plasmids. Vorinostat 19-29 P53 Homo sapiens 198-201 9811471-7 1998 These observations suggest that lovastatin induced G1 arrest of breast cell lines is through a p53 independent pathway and is mediated by decreased CDK2 activity through redistribution of CKIs from CDK4 to CDK2. Lovastatin 32-42 P53 Homo sapiens 95-98 20840854-7 2010 A dioxin-like PCB (DL-PCB 126) was used as reference and gave results that were predictable from previous studies, i.e. it attenuated BP-induced p53 response and apoptosis. Dioxins 2-8 P53 Homo sapiens 145-148 9788435-1 1998 The p53-null human lung cancer cell line H1299 was used in order to generate clones with ecdysone-inducible p53 as well as ecdysone-inducible p21waf1. Ecdysone 89-97 P53 Homo sapiens 4-7 20878066-0 2010 Amifostine enhancement of the anti-cancer effects of paclitaxel in endometrial cancer is TP53-dependent.

Amifostine 94-104 P53 Homo sapiens 154-157 9788435-1 1998 The p53-null human lung cancer cell line H1299 was used in order to generate clones with ecdysone-inducible p53 as well as ecdysone-inducible p21waf1. Ecdysone 89-97 P53 Homo sapiens 108-111 20878066-6 2010 Amifostine promotes entry into the G2-M phase through regulation of cyclin-dependent kinase-1 activity in cells with dysfunctional p53, thereby enhancing cancer cell sensitivity to paclitaxel. Amifostine 0-10 P53 Homo sapiens 131-134 9788435-1 1998 The p53-null human lung cancer cell line H1299 was used in order to generate clones with ecdysone-inducible p53 as well as ecdysone-inducible p21waf1. Ecdysone 123-131 P53 Homo sapiens 4-7 20878066-8 2010 Sensitivity to the therapeutic effect of paclitaxel in combination with amifostine was dependent upon the status of p53. Amifostine 72-82 P53 Homo sapiens 116-119 20878066-9 2010 A tumor with a nonsense TP53 mutation showed increased therapeutic response to paclitaxel and amifostine as measured by tumor weight compared to a tumor with wild- type TP53. Amifostine 94-104 P53 Homo sapiens 24-28 9766444-7 1998 In contrast, the differentiation response of p53-negative U-937 cells to 1,25-dihydroxychole-calciferol or all-trans retinoic acid was enhanced by cAMP-inducing agents at optimal concentrations and inhibited at higher concentrations. Calcitriol 73-103 P53 Homo sapiens 45-48 20878066-10 2010 Our study provides a rationale for a clinical trial of combined paclitaxel and amifostine in endometrial cancer patients whose tumors harbor TP53 mutations. Amifostine 79-89 P53 Homo sapiens 141-145 9751619-0 1998 Essential role of p53 in phenethyl isothiocyanate-induced apoptosis. phenethyl isothiocyanate 25-49 P53 Homo sapiens 18-21 20661218-6 2010 Whereas RO-3306, a selective inhibitor of cyclin-dependent kinase 1 (Cdk1), suppresses this phosphorylation at Ser315 of p53, ZM447439, targeting Aurora A/B kinases, shows no effect. RO 3306 8-15 P53 Homo sapiens 121-124 9751619-5 1998 This was demonstrated not only by results that PEITC induction of p53 protein expression and p53-dependent transactivation but also by PEITC-induced apoptosis in p53 +/+ cells but not in p53 -/- cells. phenethyl isothiocyanate 47-52 P53 Homo sapiens 66-69 20558835-0 2010 Cell cycle arrest and apoptosis in TP53 subtypes of bladder carcinoma cell lines treated with cisplatin and gemcitabine. gemcitabine 108-119 P53 Homo sapiens 35-39 9751619-5 1998 This was demonstrated not only by results that PEITC induction of p53 protein expression and p53-dependent transactivation but also by PEITC-induced apoptosis in p53 +/+ cells but not in p53 -/- cells. phenethyl isothiocyanate 47-52 P53 Homo sapiens 93-96 20558835-8 2010 TP53-wild type cells (RT4) were more sensitive to apoptosis than were mutated TP53 cells when treated with cisplatin or gemcitabine. gemcitabine 120-131 P53 Homo sapiens 0-4 20558835-8 2010 TP53-wild type cells (RT4) were more sensitive to apoptosis than were mutated TP53 cells when treated with cisplatin or gemcitabine. gemcitabine 120-131 P53 Homo sapiens 78-82 9751619-5 1998 This was demonstrated not only by results that PEITC induction of p53 protein expression and p53-dependent transactivation but also by PEITC-induced apoptosis in p53 +/+ cells but not in p53 -/- cells. phenethyl isothiocyanate 47-52 P53 Homo sapiens 93-96 20499882-5 2010 Low concentrations of the NO donor, DETA NONOate (<200 microM), exclusively nitrate Tyr327 within the tetramerization domain promoting p53 oligomerization, nuclear accumulation, and increased DNA-binding activity without p53 Ser15 phosphorylation. 2,2'-(hydroxynitrosohydrazono)bis-ethanamine 36-48 P53 Homo sapiens 138-141 20587334-0 2010 Synergistic efficacy of LBH and alphaB-crystallin through inhibiting transcriptional activities of p53 and p21. alphab-crystallin 32-49 P53 Homo sapiens 99-102 9751619-5 1998 This was demonstrated not only by results that PEITC induction of p53 protein expression and p53-dependent transactivation but also by PEITC-induced apoptosis in p53 +/+ cells but not in p53 -/- cells. phenethyl isothiocyanate 47-52 P53 Homo sapiens 93-96 20587334-6 2010 Transient transfection assays indicated that overexpression of LBH or alphaB-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both alphaB-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. alphab-crystallin 70-87 P53 Homo sapiens 130-133 9751619-7 1998 Our results demonstrate for the first time that p53 elevation is required for PEITC-induced apoptosis, which may be involved in its cancer chemopreventive activity. phenethyl isothiocyanate 78-83 P53 Homo sapiens 48-51 9576849-10 1998 The induction of p53 by H2O2 was abolished by the iron chelator deferoxamine and the protein synthesis inhibitor cycloheximide. Cycloheximide 113-126 P53 Homo sapiens 17-20 20094798-4 2010 Moreover, nutlin-3 drastically enhanced imatinib-induced apoptosis in a p53-dependent manner in various BCR/ABL-expressing cells, which included primary leukemic cells from patients with CML blast crisis or Ph+ ALL and cells expressing the imatinib-resistant E255K BCR/ABL mutant. Imatinib Mesylate 40-48 P53 Homo sapiens 72-75 9515788-0 1998 Frequent p53 mutations at dipyrimidine sites in patients with pyothorax-associated lymphoma. dipyrimidine 26-38 P53 Homo sapiens 9-12 20094798-8 2010 The present study indicates that combined treatment with nutlin-3 and imatinib activates p53 without inducing p21 and synergistically activates Bax-mediated intrinsic mitochondrial pathway to induce apoptosis in BCR/ABL-expressing cells. Imatinib Mesylate 70-78 P53 Homo sapiens 89-92 20180806-7 2010 In addition, it was observed that inhibition of heat-induced p53/HSF1 diminishes Hsp70 levels, thereby restoring the sensitivity of heat-stressed HepG2 cells to carboplatin-triggered cell death. Carboplatin 161-172 P53 Homo sapiens 61-64 9488455-0 1998 p53-dependent elevation of p21Waf1 expression by UV light is mediated through mRNA stabilization and involves a vanadate-sensitive regulatory system.

SCH 529074 11-20 P53 Homo sapiens 28-31 9803007-5 1998 DNA of the critical Tp53 exons 5-8 was amplified and run on horizontal polyacrylamide gels under defined temperature conditions (TGGE) to yield specific gel shifts and sets of homo- and heteroduplexes in case of mutation. polyacrylamide 71-85 P53 Homo sapiens 20-24 20124408-7 2010 Binding of SCH529074 to the p53 DBD is specifically displaced by an oligonucleotide with a sequence derived from the p53-response element. SCH 529074 11-20 P53 Homo sapiens 117-120 20124408-8 2010 In addition to reactivating mutant p53, SCH529074 binding inhibits ubiquitination of p53 by HDM2.

SCH 529074 140-149 P53 Homo sapiens 100-103 20124408-11 2010 Our novel findings indicate that through its interaction with p53 DBD, SCH529074 restores DNA binding activity to mutant p53 and inhibits HDM2-mediated ubiquitination. SCH 529074 71-80 P53 Homo sapiens 62-65 20124408-11 2010 Our novel findings indicate that through its interaction with p53 DBD, SCH529074 restores DNA binding activity to mutant p53 and inhibits HDM2-mediated ubiquitination. SCH 529074 71-80 P53 Homo sapiens 121-124 9436988-1 1998 We have proposed that reduced activity of inosine-5"-monophosphate dehydrogenase (IMPD; IMP:NAD oxidoreductase, EC 1.2.1.14), the rate-limiting enzyme for guanine nucleotide biosynthesis, in response to wild-type p53 expression, is essential for p53-dependent growth suppression. Guanine Nucleotides 155-173 P53 Homo sapiens 213-216 20371965-6 2010 Moreover, it was shown that cotreatment with MDA-LDL and BaP markedly induced the expression of human cytochrome P4501A1 (hCYP1A1) messenger ribonucleic acid (mRNA) and significantly induced the expressions of p53 and p21 mRNAs. mda-ldl 45-52 P53 Homo sapiens 210-213 20127688-6 2010 Knockdown of DJ-1 and MTA2, a core component of the NuRD complex, had a similar and pro-apoptotic effect on the transcriptional- and p53-dependent cell death induced by daunorubicin. Daunorubicin 169-181 P53 Homo sapiens 133-136 9436988-1 1998 We have proposed that reduced activity of inosine-5"-monophosphate dehydrogenase (IMPD; IMP:NAD oxidoreductase, EC 1.2.1.14), the rate-limiting enzyme for guanine nucleotide biosynthesis, in response to wild-type p53 expression, is essential for p53-dependent growth suppression. Guanine Nucleotides 155-173 P53 Homo sapiens 246-249 9436988-6 1998 Because of the role of IMPD in the production and balance of GTP and ATP, essential nucleotides for signal transduction, these results suggest that p53 controls cell division signals by regulating purine ribonucleotide metabolism. purine ribonucleotide 197-218 P53 Homo sapiens 148-151 9393772-0 1997 Correspondence re: J.

Imatinib Mesylate 197-205 P53 Homo sapiens 159-162 8300928-6 1993 Most patients with lesions showing positive p53 immunoreactivity had, however, been exposed to additional risk factors before receiving PUVA therapy. puva 136-140 P53 Homo sapiens 44-47 18249187-5 2008 Treatment of cells with nicotinamide, an inhibitor of Sirtuins, relieves the inhibition of p53 by Sirt2 and 14-3-3 beta/gamma. Niacinamide 24-36 P53 Homo sapiens 91-94 18315954-8 2008 Moreover, pretreatment with FeSO4 and the carbon monoxide donor CORM-2, but not biliverdin, significantly protected p53-deficient cells from SNAP-induced cell death compared with normal cells. Carbon Monoxide 42-57 P53 Homo sapiens 116-119 17724467-7 2008 The most of the p53 mutations (10/13) reactivated by amifostine were located in the part of the p53 gene coding for hydrophobic beta-sandwich structure of the DNA-binding domain. Amifostine 53-63 P53 Homo sapiens 16-19 18027850-10 2008 Belinostat also increased the expression of p21 and decreased the expression of potentially oncogenic proteins (mutant p53 and ERG). belinostat 0-10 P53 Homo sapiens 119-122 17724467-7 2008 The most of the p53 mutations (10/13) reactivated by amifostine were located in the part of the p53 gene coding for hydrophobic beta-sandwich structure of the DNA-binding domain. Amifostine 53-63 P53 Homo sapiens 96-99 8300928-7 1993 p53 gene sequencing of PUVA-associated non-melanoma skin cancer (NMSC) may clarify whether p53 mutation contributes to the development of these tumors and whether this relates to PUVA therapy or prior carcinogen exposure. puva 23-27 P53 Homo sapiens 0-3 18243168-0 2008 Sanguinarine causes DNA damage and p53-independent cell death in human colon cancer cell lines. sanguinarine 0-12 P53 Homo sapiens 35-38 8300928-7 1993 p53 gene sequencing of PUVA-associated non-melanoma skin cancer (NMSC) may clarify whether p53 mutation contributes to the development of these tumors and whether this relates to PUVA therapy or prior carcinogen exposure. puva 23-27 P53 Homo sapiens 91-94 18048073-8 2008 Simultaneous to p53 activation, psoralens induced mitochondrial depolarization, cytochrome c release, mitochondrial production of reactive oxygen species, as well as caspase-3 and -9 activation. Furocoumarins 32-41 P53 Homo sapiens 16-19 8325885-5 1993 The functional DNA target for transcriptional modulation of the IL-6 promoter by p53 species included the multiple cytokine- and second messenger-response element (-173 to -145); point mutations in the transcription factor C/EBP beta-binding site within the second messenger-response element largely blocked the ability of p53 mutants Val-135 and Phe-132 to up-regulate this promoter. Phenylalanine 347-350 P53 Homo sapiens 81-84 18179182-4 2008 In this work, double-stranded (ds-) oligonucleotides (ODNs) containing the consensus site are immobilized onto gold electrodes to capture wild-type p53. double-stranded (ds-) oligonucleotides 14-52 P53 Homo sapiens 148-151 18283158-4 2008 RESULTS: In cells that express E6, proteasome inhibition with MG132 restored p53 protein levels and decreased proliferation in a dose-dependent fashion that was significantly more pronounced compared with controls. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 62-67 P53 Homo sapiens 77-80 17981542-4 2008 Wortmannin treatment was found to decrease p53 Ser37 phosphorylation in NBS-induced cells. Wortmannin 0-10 P53 Homo sapiens 43-46 8517643-5 1993 Immunoreactive p53 was observed in the nuclei of the cancer cells in 15/33 (45%) by pAbDO-7, 11/26 (42%) by pAb1801, and 16/33 (48%) by pAbCM-1. pabcm-1 136-143 P53 Homo sapiens 15-18 18154926-4 2008 Early p53 expression was also found after NMDA treatment but diminished later. N-Methylaspartate 42-46 P53 Homo sapiens 6-9 18154926-6 2008 Blocking ERK1/2 activation with the upstream inhibitor U0126 inhibited NMDA-mediated p53 expression, suggesting that ERK1/2 signals drive the cells to apoptosis under these conditions. N-Methylaspartate 71-75 P53 Homo sapiens 85-88 18154926-11 2008 We conclude that NMDA induces an early effect that involves activation of p53, ERK, PAK1, p21 and c-jun. N-Methylaspartate 17-21 P53 Homo sapiens 74-77 18042465-5 2008 Similarly, zinc protoporphyrin (ZnPP), an inhibitor of HO, suppressed p53 expression in ARPE-19 cells, although ZnPP increased the level of HO-1 protein while inhibiting HO activity. zinc protoporphyrin 11-30 P53 Homo sapiens 70-73 18042465-5 2008 Similarly, zinc protoporphyrin (ZnPP), an inhibitor of HO, suppressed p53 expression in ARPE-19 cells, although ZnPP increased the level of HO-1 protein while inhibiting HO activity. zinc protoporphyrin 32-36 P53 Homo sapiens 70-73 18042465-7 2008 Based on these results, we conclude that HO activity is involved in the regulation of p53 expression in a ROS-independent mechanism, and also suggest that the expression of p53 in ARPE-19 cells is associated with heme metabolites such as biliverdin/bilirubin, carbon monoxide, and iron produced by the activity of HO. Carbon Monoxide 260-275 P53 Homo sapiens 173-176 18669159-10 2008 Cidofovir inhibits the growth of strongly vascularized tumors via inhibition of the growth factor FGF2, and by increasing the expression of the tumor suppressor p53, leading to apoptosis.

Arsenic 44-51 P53 Homo sapiens 78-81 17945324-11 2007 Our present investigation demonstrated that arsenic would act specifically on p53 compromised cells (either with p53 dysfunction or inhibited) to induce centrosomal abnormality and colony formation. Arsenic 44-51 P53 Homo sapiens 113-116 17945324-12 2007 These findings provided strong evidence on the carcinogenic promotional role of arsenic, especially under the condition of p53 dysfunction.

Butyrates 41-49 P53 Homo sapiens 58-61 17912033-3 2007 We found that following knock-down of Plk2 in wild-type p53 expressing H460 human non-small cell lung cancer cells there was a significant increase in cell death observed in aphidicolin-treated cells and a further increase after release from aphidicolin-block. Aphidicolin 174-185 P53 Homo sapiens 56-59 17912033-3 2007 We found that following knock-down of Plk2 in wild-type p53 expressing H460 human non-small cell lung cancer cells there was a significant increase in cell death observed in aphidicolin-treated cells and a further increase after release from aphidicolin-block. Aphidicolin 242-253 P53 Homo sapiens 56-59 17704360-6 2007 We found that the glioma cell lines repaired DSBs more slowly and less effectively than did NHAs in the clinically relevant dose range, as assessed by induction and resolution of H2AX phosphorylation, and this was most marked in the three TP53-mutated cell lines (T98G, A7, and U373). 1,2-di-(4-sulfamidophenyl)-4-butylpyrazolidine-3,5-dione 45-49 P53 Homo sapiens 239-243 17717041-11 2007 On the basis of these data, we propose that the combination of DHA and butyrate compared with butyrate alone further enhances colonocyte apoptosis by inducing a p53-independent, oxidation-sensitive, mitochondrial Ca(2+) -dependent (intrinsic) pathway.

VX680 20-26 P53 Homo sapiens 49-52 17569822-3 2007 Importantly, the imatinib resistance mechanism in these variants also included aberrant acetylation of nonhistone proteins such as p53, Ku70, and Hsp90 that was due to upregulation of histone deacetylases (HDACs) and down-regulation of histone acetyltransferase (HAT). Imatinib Mesylate 17-25 P53 Homo sapiens 131-134 17569822-4 2007 In comparison with K562 cells, the imatinib-resistant variants showed up-regulation of HDAC1, -2, and -3 (class I HDACs) and class III SIRT1 and down-regulation of CBP/p300 and PCAF with HAT activity, and thereby p53 and cytoplasmic Ku70 were aberrantly acetylated. Imatinib Mesylate 35-43 P53 Homo sapiens 213-216 17569822-7 2007 These results indicate that alteration of the normal balance of HATs and HDACs leads to deregulated acetylation of Hsp90, p53, and Ku70 and thereby leads to imatinib resistance, suggesting the importance of the acetylation status of apoptosis-related nonhistone proteins in Bcr-Abl-independent imatinib resistance. Imatinib Mesylate 157-165 P53 Homo sapiens 122-125 11931974-5 2002 The present study investigated the regulation of p53 on vanadate-induced cell growth arrest using both p53 wild type C141 cells and p53 deficient embryo fibroblasts (p53 -/-).

Vorinostat 126-157 P53 Homo sapiens 27-30 12556448-9 2003 We also demonstrate that the susceptibility to TSA- and SAHA-induced cell death is regulated by p53. Vorinostat 56-60 P53 Homo sapiens 96-99 14871987-6 2004 Deguelin treatment did not affect Bcl-2 protein levels but increased expression levels of the proapoptotic protein p53 and the cyclin-dependent kinase inhibitors p21 and p27 in the squamous HBE cells. deguelin 0-8 P53 Homo sapiens 115-118 15055483-6 2004 The reduction of Cr (VI) to Cr (III) results in the formation of reactive intermediates that together with oxidative stress and oxidative tissue damage, and a cascade of cellular events including modulation of apoptosis regulatory gene p53 contribute to the cytotoxicity, genotoxicity and carcinogenicity of Cr(VI)-containing compounds. cr (iii) 28-36 P53 Homo sapiens 236-239 35331214-11 2022 Furthermore, aggressive-variant prostate cancer (AVPC), defined as 2 or more aberrations in TP53, RB1 and/or PTEN, was associated with elevated sphingolipids. Sphingolipids 144-157 P53 Homo sapiens 92-96 35331214-14 2022 CONCLUSIONS: Elevated circulating sphingolipids were associated with AR, TP53, RB1, PI3K and AVPC aberrations in mCRPC, and the combination of lipid and genetic abnormalities conferred a worse prognosis. Sphingolipids 34-47 P53 Homo sapiens 73-77 14578369-1 2004 We recently reported that pyruvate inhibited translocation and activation of p53 caused by DNA damage due to oxidant injury (Lee YJ, Kang IJ, Bunger R, and Kang YH. Pyruvic Acid 26-34 P53 Homo sapiens 77-80 12618886-5 2003 Compared with p53-deficient cells, p53-proficient cells exhibited low-level resistance to amifostine-induced apoptosis. Amifostine 90-100 P53 Homo sapiens 14-17 12618886-5 2003 Compared with p53-deficient cells, p53-proficient cells exhibited low-level resistance to amifostine-induced apoptosis. Amifostine 90-100 P53 Homo sapiens 35-38 35408798-9 2022 Indeed, EAPB0503 selectively downregulates HDM2 expression and activates the p53 pathway in NPM1c expressing cells, resulting in apoptosis. EAPB0503 8-16 P53 Homo sapiens 77-80 12618886-6 2003 Amifostine induced the expression of p53 protein in p53-proficient cells and the expression of p21 protein in both p53-proficient and -deficient cells. Amifostine 0-10 P53 Homo sapiens 37-40 12618886-6 2003 Amifostine induced the expression of p53 protein in p53-proficient cells and the expression of p21 protein in both p53-proficient and -deficient cells. Amifostine 0-10 P53 Homo sapiens 52-55 12618886-6 2003 Amifostine induced the expression of p53 protein in p53-proficient cells and the expression of p21 protein in both p53-proficient and -deficient cells. Amifostine 0-10 P53 Homo sapiens 52-55 12618886-7 2003 These findings indicate that amifostine-induced G1 arrest and cytoprotection are mediated via a pathway that is dependent on p53 protein and that amifostine-induced expression of p21 protein is not sufficient to sustain a G1 arrest or to mediate cytoprotection. Amifostine 29-39 P53 Homo sapiens 125-128 12618886-8 2003 In addition, these findings identify p53 protein as a mechanism of resistance to amifostine-induced apoptosis.British Amifostine 81-91 P53 Homo sapiens 37-40 15048068-3 2004 Here, we demonstrated that STI571 also induces growth arrest by activating the Chk2-Cdc25A-Cdk2 axis, a pathway complementary to p53 in the activation of G(1)/S cell cycle checkpoint.

Fluorescein 154-165 P53 Homo sapiens 89-92 11055588-7 2000 RESULTS: We demonstrate that FTS treatment alters the morphology and blocks the growth of SW480 and HT-29 colon cancer cells by both reducing the total amount of Ras and up-regulating the tumor suppressor p53. fts 29-32 P53 Homo sapiens 205-208 11055588-9 2000 p53 antisense oligonucleotides not only reduced the level of p53 proteins but correspondingly also blocked the expression of p21(waf1/cip1) in FTS-treated colon cancer cells. fts 143-146 P53 Homo sapiens 0-3 11055588-9 2000 p53 antisense oligonucleotides not only reduced the level of p53 proteins but correspondingly also blocked the expression of p21(waf1/cip1) in FTS-treated colon cancer cells. fts 143-146 P53 Homo sapiens 61-64 10896848-11 2000 Compared with adriamycin, a known inducer of p53, MCTP-treated HPAEC expressed p53 only at high concentrations and p53 expression was not coordinated with G2 arrest or polyploidy. monocrotaline pyrrole 50-54 P53 Homo sapiens 45-48 10896848-11 2000 Compared with adriamycin, a known inducer of p53, MCTP-treated HPAEC expressed p53 only at high concentrations and p53 expression was not coordinated with G2 arrest or polyploidy. monocrotaline pyrrole 50-54 P53 Homo sapiens 79-82 10896848-11 2000 Compared with adriamycin, a known inducer of p53, MCTP-treated HPAEC expressed p53 only at high concentrations and p53 expression was not coordinated with G2 arrest or polyploidy. monocrotaline pyrrole 50-54 P53 Homo sapiens 79-82 10896848-12 2000 We conclude that HPAEC treated with low concentrations of MCTP develop G2 arrest in association with persistent cyclin B1 expression, failure to completely activate cdc2, and continued DNA synthesis through a pathway that is unrelated to altered expression of p53. monocrotaline pyrrole 58-62 P53 Homo sapiens 260-263 10891461-8 2000 In contrast, p53 was stabilized by MG132 or LLnL in malignant and normal cells undergoing apoptosis, indicating that in normal lymphocytes p53 is regulated mainly by calpains and not by the ubiquitin-proteasome system. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 35-40 P53 Homo sapiens 13-16 10814675-5 2000 METHODS: Here we have mapped the distribution of adducts induced by diol epoxides of additional PAHs: chrysene (CDE), 5-methylchrysene (5-MCDE), 6-methylchrysene (6-MCDE), benzo[c]phenanthrene (B[c]PDE), and benzo[g]chrysene (B[g]CDE) within exons 5, 7, and 8 of the p53 gene in human bronchial epithelial cells. diol epoxides 68-81 P53 Homo sapiens 267-270 10775450-0 2000 Initiation of rapid, P53-dependent growth arrest in cultured human skin fibroblasts by reactive chlorine species. reactive chlorine species 87-112 P53 Homo sapiens 21-24 10811472-5 2000 Although wt-p53 transduction before drug treatment induced chemoresistance, p53 transduction in cells treated previously with gemcitabine increased cytotoxicity. gemcitabine 126-137 P53 Homo sapiens 76-79 10767618-9 2000 With the advent of new techniques of molecular biology, mutations were investigated in the ras and p53 genes of tumors induced by vinyl chloride and urethane. Vinyl Chloride 130-144 P53 Homo sapiens 99-102 11324420-11 2000 The Western blot assay from cell extracts showed that the levels of protein p53 were decreased after ceramide treatment. Ceramides 101-109 P53 Homo sapiens 76-79 10745271-8 2000 Ceramide-induced cell death was associated with increased c-myc, p53, Bax and p27kip1 levels; in contrast, cells transfected with Nur77 (A20Nur77), resistant to ceramide-induced apoptosis, showed a marked downregulation of p53 after ceramide treatment, with neither Bax nor p27kip1 induction. Ceramides 0-8 P53 Homo sapiens 65-68 10745271-8 2000 Ceramide-induced cell death was associated with increased c-myc, p53, Bax and p27kip1 levels; in contrast, cells transfected with Nur77 (A20Nur77), resistant to ceramide-induced apoptosis, showed a marked downregulation of p53 after ceramide treatment, with neither Bax nor p27kip1 induction.

Arsenic 21-28 P53 Homo sapiens 14-17 10677095-3 2000 Arsenic treatment has been shown to cause hypermethylation of the TP53 gene in lung carcinoma cell lines, but it is not known if this occurs in vivo in arsenic-related BCCs. Arsenic 0-7 P53 Homo sapiens 66-70 10677095-9 2000 RESULTS: Arsenic-related BCCs express p53 less often and at a lower intensity than sporadic BCCs (P = .001; 2-tailed test). Arsenic 9-16 P53 Homo sapiens 38-41 10677095-10 2000 The BCCs from sun-exposed sites, whether arsenic related or sporadic, more frequently showed overexpression of p53 than those from less-exposed areas (P = .004; 2-tailed test). Arsenic 41-48 P53 Homo sapiens 111-114 10677095-12 2000 CONCLUSIONS: These results are consistent with the hypothesis that the TP53 gene is down-regulated by methylation in arsenic-related BCC, particularly those from less-exposed sites. Arsenic 117-124 P53 Homo sapiens 71-75 10682666-1 2000 The purpose of this work was to analyse the ability of p53 and thymidilate synthase (TS) primary tumour expression to retrospectively predict clinical response to chemotherapy and long-term prognosis in patients with advanced colorectal cancers homogeneously treated by methotrexate (MTX)-modulated-5-fluorouracil (5-FU-FA). 5-fu-fa 315-322 P53 Homo sapiens 55-58 11498362-2 2000 Arsenic may be effective in counteracting drug resistance because it appears to induce apoptosis in tumor cells independently of p53 activation, thereby allowing it to be directed against p53-defective cancers. Arsenic 0-7 P53 Homo sapiens 129-132 11498362-2 2000 Arsenic may be effective in counteracting drug resistance because it appears to induce apoptosis in tumor cells independently of p53 activation, thereby allowing it to be directed against p53-defective cancers. Arsenic 0-7 P53 Homo sapiens 188-191 10935502-0 1999 p53-independent inhibition of proliferation and p21(WAF1/Cip1)-modulated induction of cell death by the antioxidants N-acetylcysteine and vitamin E. Vitamin E 138-147 P53 Homo sapiens 0-3 10935502-5 1999 The antioxidants, N-acetylcysteine (NAC) and vitamin E either inhibited proliferation in a p53-independent manner without affecting cell viability or induced cell death. Vitamin E 45-54 P53 Homo sapiens 91-94 10592324-6 1999 The genotoxic action of AFB1 was completely different from that of the alkylating agent ethyl-methane-sulfonate, where 28/30 induced mutations were linked to the TP53 target gene. Ethyl Methanesulfonate 88-111 P53 Homo sapiens 162-166 10597243-2 1999 Here, we identify a cis-acting 66-nucleotide U-rich sequence in the human p53 mRNA 3" untranslated region that mediates translational repression. 66-nucleotide 31-44 P53 Homo sapiens 74-77 10536167-7 1999 Inhibition of DNA replication by aphidicolin prevented the accumulation of p53 in S and G2/M but had no effect on its induction in G1 cells. Aphidicolin 33-44 P53 Homo sapiens 75-78 10536167-9 1999 Thus, the changes observed in S phase cells (nuclear accumulation of p53 preventable by aphidicolin, induction of Bax, apoptosis), triggered by the collisions of DNA replication forks with the CPT-induced lesions, were distinct from the changes in G1 (nuclear p53 accumulation unaffected by aphidicolin, induction of p21WAF1) presumably triggered by collisions of RNA polymerase with the CPT-lesions. Aphidicolin 88-99 P53 Homo sapiens 69-72 10491313-0 1999 Arsenic disrupts cellular levels of p53 and mdm2: a potential mechanism of carcinogenesis. Arsenic 0-7 P53 Homo sapiens 36-39 10491313-5 1999 We propose the disruption of the p53-mdm2 loop regulating cell cycle arrest as a model for arsenic-related skin carcinogenesis and it may be important in tumors with elevated mdm2 levels. Arsenic 91-98 P53 Homo sapiens 33-36 10423403-7 1999 In the four specimens with abnormal PCR-SSCP bands, p53 gene mutation was identified by direct sequencing and revealed the same point mutation at codon 248 (CGG-to-CTG transversion) of exon 7 in all four specimens. ctg 164-167 P53 Homo sapiens 52-55 10471039-9 1999 In addition, in contrast to cisplatin, the triplatinum complex was very effective as an inducer of apoptosis in a lung carcinoma cell line carrying mutant p53. triplatinum 43-54 P53 Homo sapiens 155-158 10652612-8 1999 The experiments indicated that indole-3-carbinol suppressed MCF-7 cell growth in part by induction of apoptosis which was independent of p53 and bax expression and that the effect caused by indole-3-carbinol was partially due to its conversion to a more potent compound, 3,3"-diindolylmethane, in vitro. indole-3-carbinol 31-48 P53 Homo sapiens 137-140 10407675-3 1999 The TP53 exon 8 sequence was amplified from genomic DNA samples under conditions of high polymerase fidelity using a fluorescein-labeled primer. Fluorescein 117-128 P53 Homo sapiens 4-8 10397243-0 1999 Arsenic induces apoptosis through a c-Jun NH2-terminal kinase-dependent, p53-independent pathway. Arsenic 0-7 P53 Homo sapiens 73-76 10397243-7 1999 Taken together with previous findings that p53 mutations are involved in approximately 50% of all human cancers and nearly all chemotherapeutic agents kill cancer cells mainly by apoptotic induction, we suggest that arsenic may be a useful agent for the treatment of cancers with p53 mutation. Arsenic 216-223 P53 Homo sapiens 43-46 10397243-7 1999 Taken together with previous findings that p53 mutations are involved in approximately 50% of all human cancers and nearly all chemotherapeutic agents kill cancer cells mainly by apoptotic induction, we suggest that arsenic may be a useful agent for the treatment of cancers with p53 mutation. Arsenic 216-223 P53 Homo sapiens 280-283 10340385-8 1999 Inactivation in these cells of p53 function by transduction of dominant-negative C-terminal p53 fragment (genetic suppressor element #22, GSE22) or mutant p53s significantly increased the frequency of both spontaneous and ras-induced karyotypic changes. gse22 138-143 P53 Homo sapiens 31-34 10340385-8 1999 Inactivation in these cells of p53 function by transduction of dominant-negative C-terminal p53 fragment (genetic suppressor element #22, GSE22) or mutant p53s significantly increased the frequency of both spontaneous and ras-induced karyotypic changes. gse22 138-143 P53 Homo sapiens 92-95 10340385-8 1999 Inactivation in these cells of p53 function by transduction of dominant-negative C-terminal p53 fragment (genetic suppressor element #22, GSE22) or mutant p53s significantly increased the frequency of both spontaneous and ras-induced karyotypic changes. gse22 138-143 P53 Homo sapiens 92-95 10224095-3 1999 Specifically, CLDC-based intravenous delivery of the p53 and GM-CSF genes were each as effective as the potent antiangiogenic gene, angiostatin, in reducing both tumor metastasis and tumor angiogenesis. cldc 14-18 P53 Homo sapiens 53-56 10224095-5 1999 CLDC-based intravenous delivery of the human wild type p53 gene transfected up to 80% of tumor cells metastatic to lung. cldc 0-4 P53 Homo sapiens 55-58 9973219-3 1999 CENU-lex sequence specificity for DNA alkylation was determined using 32P-end-labeled restriction fragments of the p53 cDNA. Phosphorus-32 70-73 P53 Homo sapiens 115-118 9927186-6 1999 Furthermore, Bcl-2 protein was shown to specifically suppress the p53-mediated transactivation of p21CIP1/WAF1 and PG13-CAT, which is a typical p53-binding-site reporter construct. pg13-cat 115-123 P53 Homo sapiens 66-69 9927186-6 1999 Furthermore, Bcl-2 protein was shown to specifically suppress the p53-mediated transactivation of p21CIP1/WAF1 and PG13-CAT, which is a typical p53-binding-site reporter construct. pg13-cat 115-123 P53 Homo sapiens 144-147 10048758-9 1999 These results suggest that members of the organochlorine class are able to downregulate Rb expression at the post-transcriptional level, an effect similar to that on p53 tumor suppressor previously reported by our laboratory. Hydrocarbons, Chlorinated 42-56 P53 Homo sapiens 166-169 10228869-10 1999 The percentage of p53 overexpression with positive DO7 staining was 20.0% (6 out of 30).

Vinyl Chloride 75-89 P53 Homo sapiens 52-55 11601009-2 1999 METHODS: By LipofectaMINE and electraporation methods, this mutant p53 gene which lacked of exon 1 and intron 1 expression vector driven by CMV promoter was co-transfected with PCMVneo into PG cell in which dominant negative p53 pre-exists. Lipofectamine 12-25 P53 Homo sapiens 67-70 9886568-0 1998 Oltipraz, a novel inhibitor of hepatitis B virus transcription through elevation of p53 protein. oltipraz 0-8 P53 Homo sapiens 84-87 9886568-8 1998 In addition, oltipraz induces endogenous wild-type p53 protein in a dose- and time-course-dependent manner. oltipraz 13-21 P53 Homo sapiens 51-54 9886568-9 1998 Taken together, we speculate that the effects of oltipraz against replication of HBV and specific blocking of HBV transcription may be through the induction of p53-mediated pathway in 2.2.15 cells. oltipraz 49-57 P53 Homo sapiens 160-163 9719464-6 1998 These findings suggest that ceramide-induced apoptosis is associated with the upregulation of p21 mRNA and protein in a p53-independent pathway. Ceramides 28-36 P53 Homo sapiens 120-123 9695075-5 1998 These findings suggest that butyrate arrests the growth of WiDr by activating the WAF1 promoter through specific Sp1 sites in a p53-independent fashion. Butyrates 28-36 P53 Homo sapiens 128-131 9695075-9 1998 Therefore the p53-independent activation of WAF1 by butyrate could be applied to the prevention of cancer when p53 is mutated. Butyrates 52-60 P53 Homo sapiens 14-17 9695075-9 1998 Therefore the p53-independent activation of WAF1 by butyrate could be applied to the prevention of cancer when p53 is mutated. Butyrates 52-60 P53 Homo sapiens 111-114 9605744-3 1998 Using a UvrABC incision method, we have found that cytosine methylation greatly enhances guanine alkylation at all CpG sites in the p53 gene by a variety of carcinogens, including benzo(a)pyrene diol epoxide, benzo(g)chrysene diol epoxide, aflatoxin B1 8,9-epoxide, and N-acetoxy-2-acetylaminofluorene. aflatoxin B1-2,3-oxide 240-264 P53 Homo sapiens 132-135 9565608-9 1998 The results suggest that ADP-ribose polymers could play a role in regulating the DNA binding properties of p53. adp-ribose polymers 25-44 P53 Homo sapiens 107-110 9499438-8 1998 The elevation of p53 protein levels in MCF-7 cells treated with CPT was significantly inhibited by preincubation with DNA breaks inhibitor aphidicolin, while the elevation of p21WAF1/CIP1 protein levels was not inhibited.

Butyrates 0-8 P53 Homo sapiens 70-73 9268365-2 1997 We examined the effect of butyrate on the expression of WAF1/Cip1, a potent inhibitor of cyclin-dependent kinases, and its relation to growth arrest in a p53-mutated human colon cancer cell line WiDr. Butyrates 26-34 P53 Homo sapiens 154-157 9268365-7 1997 These findings suggest that butyrate arrests the growth of WiDr by activating the WAF1/Cip1 promoter through specific Sp1 sites in a p53-independent fashion. Butyrates 28-36 P53 Homo sapiens 133-136 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair. Cyclophosphamide 117-133 P53 Homo sapiens 58-61 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair. Cyclophosphamide 117-133 P53 Homo sapiens 161-164 9291435-6 1997 Our results suggest that mdm-2, which is known to disrupt p53 function, sensitizes ovarian-cancer cells to cisplatin/cyclophosphamide, possibly by inhibition of p53-mediated G1 cell-cycle arrest and p53-stimulated nucleotide-excision repair.

The induction of p53 protein seemed to be dependent on the increase of p53 mRNA level, which was inhibited by CHX treatment. delta 12-pgj2 135-148 P53 Homo sapiens 28-31 7628635-3 1995 Western analysis using anti-p53 or anti-WAF1 monoclonal antibodies demonstrated that these two protein levels were increased 3 h after delta 12-PGJ2 treatment, and accumulated for up to 12 h. The induction of p53 protein seemed to be dependent on the increase of p53 mRNA level, which was inhibited by CHX treatment. delta 12-pgj2 135-148 P53 Homo sapiens 209-212 7628635-3 1995 Western analysis using anti-p53 or anti-WAF1 monoclonal antibodies demonstrated that these two protein levels were increased 3 h after delta 12-PGJ2 treatment, and accumulated for up to 12 h.

Phytic Acid 184-187 P53 Homo sapiens 139-142 9673359-8 1998 These data demonstrate that IP6 up-regulates the expression of the tumor suppressor gene p53 and p21WAF1/CIP1 gene and their modulation may be one of the mechanisms of the anti-neoplastic action of IP6. Phytic Acid 28-31 P53 Homo sapiens 89-92 9673359-8 1998 These data demonstrate that IP6 up-regulates the expression of the tumor suppressor gene p53 and p21WAF1/CIP1 gene and their modulation may be one of the mechanisms of the anti-neoplastic action of IP6.

Arsenic 68-75 P53 Homo sapiens 130-133 22170404-7 2012 Inhibition of AMPK, p53, or DAPK attenuated SB203580-induced autophagy. SB 203580 44-52 P53 Homo sapiens 20-23 21543203-7 2012 We also observed that flavokawain B caused the G2/M phase arrest that was mediated through reductions in the levels of cyclin A, cyclin B1, Cdc2 and Cdc25C and increases in p21/WAF1, Wee1 and p53 levels. flavokawain B 22-35 P53 Homo sapiens 192-195 23556117-4 2012 Other recent advances include a better understanding of the pathogenesis of disease including haplodeficiency of several candidate genes, and elucidation of the lenalidomide-specific effect on two phosphatases ultimately leading to p53 degradation in the erythroid progenitors and cell cycle arrest in earlier myeloid progenitors.

Lenalidomide 136-148 P53 Homo sapiens 11-15 22261445-2 2012 However, whether aberrant p53 nuclear expression detected by immunohistochemical analysis can be used as a surrogate marker for del(17p13)(TP53) in prognostic evaluation of lenalidomide-treated relapsed/refractory MM remains unclear. Lenalidomide 173-185 P53 Homo sapiens 26-29 22261445-7 2012 Our results suggest that p53 nuclear expression is associated with adverse outcome in patients with relapsed/refractory MM receiving lenalidomide-based therapy and that p53 immunohistochemical analysis may serve as a simple, rapid method to predict del(17p13)(TP53) in this patient subgroup. Lenalidomide 133-145 P53 Homo sapiens 25-28 22056254-2 2012 Here we determine the effect of the tumor suppressor protein, p53, on trafficking (64)Cu to tumor cell nuclei from DOTA vs. CB-TE2A-conjugated agonist Y3-TATE and the antagonist (64)Cu-CB-TE2A-sst2-ANT in cell lines that are positive or negative for p53. diflorasone 154-158 P53 Homo sapiens 62-65 26316897-0 2012 Development of in vitro gene delivery system using ORMOSIL nanoparticle: Analysis of p53 gene expression in cultured breast cancer cell (MCF-7). ormosil 51-58 P53 Homo sapiens 85-88 26316897-3 2012 In this context, ORMOSIL nanoparticles had been synthesized and incubated along with pCMV-Myc (3.8 kb) plasmid vector construct carrying p53gene, and transfected into the breast cancer cell line MCF-7 cells. ormosil 17-24 P53 Homo sapiens 137-140 21964832-8 2012 We observed that TPA-induced down-regulation of p53 protein was prevented by ALLN and MG132, but not by chloroquine. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 98-103 P53 Homo sapiens 60-63 23050037-10 2012 Since the treatment of senescent cells with phosphoinositide 3-kinase inhibitor, wortmannin, suppressed p53 phosphorylation, it is suggested that amplification of DNA damage signaling sustains persistent activation of ATM-p53 pathway, which is essential for replicative senescence. Wortmannin 81-91 P53 Homo sapiens 104-107 23050037-10 2012 Since the treatment of senescent cells with phosphoinositide 3-kinase inhibitor, wortmannin, suppressed p53 phosphorylation, it is suggested that amplification of DNA damage signaling sustains persistent activation of ATM-p53 pathway, which is essential for replicative senescence.

Vinyl Chloride 101-115 P53 Homo sapiens 42-45 21880715-10 2011 Meanwhile, mutation of EDEE residues impairs both the binding and the enzymatic activity of SMYD2 to p53 Lys-370. edee 23-27 P53 Homo sapiens 101-104 21832879-0 2011 Metabolic utilization of exogenous pyruvate by mutant p53 (R175H) human melanoma cells promotes survival under glucose depletion. Pyruvic Acid 35-43 P53 Homo sapiens 54-57 21832879-6 2011 Metabolic utilization and survival under glucose depletion was increased by pyruvate in mutant p53 (R175H) cells. Pyruvic Acid 76-84 P53 Homo sapiens 95-98 21832879-7 2011 Our results show for the first time that melanoma cells harbouring a p53 (R175H) mutation increase: a) survival under glucose depletion, counteracted by NADPH-oxidase modulators like DPI; b) resistance to DPI when supplemented with exogenous pyruvate. Pyruvic Acid 242-250 P53 Homo sapiens 69-72 21933400-13 2011 Changes in the repair kinetics of DSB p53-independent apoptosis with p21 involvement may be part of the underlying mechanisms for radio-sensitization by SAHA. Vorinostat 153-157 P53 Homo sapiens 38-41 21327578-6 2011 BTG2/p53 were expressed early after DEN treatment, peaked at 5 weeks and decreased gradually thereafter. Diethylnitrosamine 36-39 P53 Homo sapiens 5-8 21674128-6 2011 TP53-depleted HCT116 cultures also had DSBs after high-dose 5-FU treatment but experienced a (transient) G1/S cell cycle arrest that protected them from apoptosis. 1,2-di-(4-sulfamidophenyl)-4-butylpyrazolidine-3,5-dione 39-43 P53 Homo sapiens 0-4 21878502-3 2011 We demonstrate here a crucial role of the gammaH2AX-ATM-p53 pathway in the regulation of the apoptotic outcome of MC resulting from cells entering mitosis with damaged DNA. Methylcholanthrene 114-116 P53 Homo sapiens 56-59 21914522-11 2011 The results of the study in West Bengal suggest that deficiency in DNA repair capacity, perturbation of methylation of promoter region of p53 and p16 genes, and genomic methylation alteration may be involved in arsenic-induced disease manifestation in humans. Arsenic 211-218 P53 Homo sapiens 138-141 21914522-12 2011 P53 polymorphism has been found to be associated with increased occurrence of arsenic-induced keratosis. Arsenic 78-85 P53 Homo sapiens 0-3 21441950-4 2011 We show here that the anthracyclines doxorubicin, daunorubicin and epirubicin further increase the amounts of mutant p53 mRNA and protein in cancer cells. Daunorubicin 50-62 P53 Homo sapiens 117-120 21482024-10 2011 The ERCC1 and p53 genes may play an integral role in the synergism between Ki23057 and chemotherapeutic agents in drug-resistant cell lines.

Arsenic 12-19 P53 Homo sapiens 148-151 21756780-14 2011 CONCLUSION: Arsenic pollution caused by coal-burning can cause the hypermethylation of p53 gene in promoter region, hypomethylation and mutation of p53 gene (exon 5), and the changes of methylation of p53 gene are related with its mutation and might be one of the important etiological factors of arsenic pathogenicity or carcinogenesis. Arsenic 12-19 P53 Homo sapiens 148-151 21321360-6 2011 Importantly, lenalidomide decreased the percentage and clonogenicity of SP cells, and also induced phosphorylation changes in Akt, GSK-3alpha/beta, MEK1, c-Jun, p53, and p70S6K in SP cells. Lenalidomide 13-25 P53 Homo sapiens 161-164 21435243-9 2011 The inhibition of Akt activity and p53-independent p21/CDKN1A and GADD45A overexpression were identified as the main molecular events responsible for CTet activity in MCF-7 and p53-mutant MDA-MB-231 cells. ctet 150-154 P53 Homo sapiens 35-38 21435243-9 2011 The inhibition of Akt activity and p53-independent p21/CDKN1A and GADD45A overexpression were identified as the main molecular events responsible for CTet activity in MCF-7 and p53-mutant MDA-MB-231 cells. ctet 150-154 P53 Homo sapiens 177-180 21107702-10 2011 To reactivate mutant p53 and reverse chemoresistance, ellipticine (5,11-dimethyl-6H-pyrido[4,3-b]carbazole) was used to treat mutant p53 cells. ellipticine 54-65 P53 Homo sapiens 21-24 21107702-10 2011 To reactivate mutant p53 and reverse chemoresistance, ellipticine (5,11-dimethyl-6H-pyrido[4,3-b]carbazole) was used to treat mutant p53 cells. ellipticine 54-65 P53 Homo sapiens 133-136 21107702-10 2011 To reactivate mutant p53 and reverse chemoresistance, ellipticine (5,11-dimethyl-6H-pyrido[4,3-b]carbazole) was used to treat mutant p53 cells. ellipticine 67-106 P53 Homo sapiens 21-24 21107702-10 2011 To reactivate mutant p53 and reverse chemoresistance, ellipticine (5,11-dimethyl-6H-pyrido[4,3-b]carbazole) was used to treat mutant p53 cells. ellipticine 67-106 P53 Homo sapiens 133-136 21107702-11 2011 Ellipticine enhanced p53 mitochondrial translocation, decreased Complex I activity, and sensitized p53 mutant cells to doxorubicin-induced apoptosis. ellipticine 0-11 P53 Homo sapiens 21-24 21107702-11 2011 Ellipticine enhanced p53 mitochondrial translocation, decreased Complex I activity, and sensitized p53 mutant cells to doxorubicin-induced apoptosis. ellipticine 0-11 P53 Homo sapiens 99-102 21107702-13 2011 Therefore, restoring mutant p53 by ellipticine may sensitize these cells to chemotherapy. ellipticine 35-46 P53 Homo sapiens 28-31 21324703-0 2011 Synthesis and biological evaluation of imidazolo[2,1-b]benzothiazole derivatives, as potential p53 inhibitors. imidazolo[2,1-b]benzothiazole 39-68 P53 Homo sapiens 95-98 21324703-3 2011 The biochemical and biological evaluations supported that compounds of the tetrahydrobenzothiazole series were inhibitors of the p53 transcriptional activity and were effective in enhancing paclitaxel-induced apoptosis. tetrahydrobenzothiazole 75-98 P53 Homo sapiens 129-132 20473904-3 2011 The EBNA-5 binding to MDM2 counteracted destabilizing effect of the latter on the p53. ebna-5 4-10 P53 Homo sapiens 82-85 21270522-2 2011 However, it is still unclear whether the p53 status of the target cell might influence the sensitivity to Saq-NO. saquinavir-NO 106-112 P53 Homo sapiens 41-44 21270522-3 2011 In this study we evaluated the in vitro and in vivo activity of Saq-NO on the p53-deficient hormone resistant prostate cancer PC-3 cells. saquinavir-NO 64-70 P53 Homo sapiens 78-81 21035490-2 2011 Whereas some investigations have suggested that ceramide and more complex sphingolipids function upstream of p53 or in a p53-independent manner, other studies propose that p53-dependent alterations in these sphingolipids can also contribute to apoptosis. Ceramides 48-56 P53 Homo sapiens 109-112 21035490-4 2011 However, whereas various components of the sphingolipid and p53 pathways may simultaneously function to elicit apoptosis and/or growth inhibition, SMase and SK1 may undergo explicit regulation by p53 that could contribute to ceramide-induced senescence in cells. Ceramides 225-233 P53 Homo sapiens 196-199 21273598-4 2011 RESULTS: Renieramycin M treatment caused p53 activation, which subsequently down-regulated anti-apoptotic MCL-1 and BCL-2 proteins, while the level of pro-apoptotic BAX protein was not altered. renieramycin M 9-23 P53 Homo sapiens 41-44 21273598-7 2011 CONCLUSION: These results reveal that renieramycin M induced lung cancer cells apoptosis through p53-dependent pathway and the compound may inhibit progression and metastasis of lung cancer cells. renieramycin M 38-52 P53 Homo sapiens 97-100 22041910-0 2011 High dose of pyridoxine induces IGFBP-3 mRNA expression in MCF-7 cells and its induction is inhibited by the p53-specific inhibitor pifithrin-alpha.

Daunorubicin 61-73 P53 Homo sapiens 84-87 21187919-8 2010 Furthermore, the combination of MNP-Fe3O4 with adriamycin or daunorubicin increased p53 protein levels and decreased NF-kappaB protein levels more than adriamycin or daunorubicin alone, indicating that MNP-Fe3O4 could enhance the effect of chemotherapeutic drugs on p53 and NF-kappaB. Daunorubicin 61-73 P53 Homo sapiens 266-269 20655369-8 2010 Inhibition of cellular CYP3A4 or CYP1A/1B suppressed the aflatoxin B(1)- and dimethylbenz[a]anthracene-mediated P53 response, respectively, indicating that HepG2 cells are capable of metabolizing these compounds in a CYP1A/B/3A4-dependent manner. anthracene 92-102 P53 Homo sapiens 112-115 20976259-7 2010 Cell lines with truncation, deletion, and null status of p53 were resistant to gemcitabine without apparent relationship to RRM1 levels. gemcitabine 79-90 P53 Homo sapiens 57-60 20976259-9 2010 The impact of p53 mutations in patients treated with gemcitabine should be studied in prospective clinical trials to develop a model with improved precision of predicting drug efficacy. gemcitabine 53-64 P53 Homo sapiens 14-17 20421190-9 2010 Although Akt signaling was activated, the accumulation of p53 led cells to apoptosis after treatment with 50 nM microcystin-LR for 24 hr. Lawrencium 124-126 P53 Homo sapiens 58-61 20662736-7 2010 Anthracycline (topoisomerase II inhibitors such as mitoxantrone and ellipticine) and camptothecin (topoisomerase I inhibitor) derivatives including topotecan induce DNA double strand breaks, which activate the p53 pathway through the ataxia telangiectasia mutated-checkpoint kinase 2 (ATM-CHK2) DNA damage response pathway. ellipticine 68-79 P53 Homo sapiens 210-213 20662736-8 2010 Although mitoxantrone, ellipticine, camptothecin, and topotecan all exhibited concentration-dependent disruption of the p53-hDM2 PPIB, they were much less potent than Nutlin-3. ellipticine 23-34 P53 Homo sapiens 120-123 19859801-5 2010 We also found that treating MCF7 cells with DAC restored induction of DFNA5 by p53, as well as by two other p53 family genes, p63gamma and p73beta. Decitabine 44-47 P53 Homo sapiens 79-82 19859801-5 2010 We also found that treating MCF7 cells with DAC restored induction of DFNA5 by p53, as well as by two other p53 family genes, p63gamma and p73beta. Decitabine 44-47 P53 Homo sapiens 108-111 20226587-3 2010 Co-treatment of etoposide and KG-135 markedly elevated the expression and phosphorylation at the serine 15 residue of p53 as well as the cellular levels of Bax and p21(Waf1/Cip1). kg-135 30-36 P53 Homo sapiens 118-121 20226587-4 2010 The increased accumulation and phosphorylation of p53 (Ser15) were attenuated by treatment of cells with wortmannin, a pan-phosphatidylinositol-3 kinase inhibitor. Wortmannin 105-115 P53 Homo sapiens 50-53 20226587-6 2010 Our results indicate that etoposide-induced apoptosis in HeLa cells can be potentiated in the presence of KG-135 through a mechanism that involves the stabilization of p53 and the stimulation of Bax- and p21-mediated apoptotic signaling pathways. kg-135 106-112 P53 Homo sapiens 168-171 20554748-0 2010 PTEN and p53 cross-regulation induced by soy isoflavone genistein promotes mammary epithelial cell cycle arrest and lobuloalveolar differentiation. isoflavone genistein 45-65 P53 Homo sapiens 9-12 20558137-0 2010 Ascochlorin, an isoprenoid antibiotic, induces G1 arrest via downregulation of c-Myc in a p53-independent manner. ascochlorin 0-11 P53 Homo sapiens 90-93 20558137-5 2010 Furthermore, we used a chromatin immunoprecipitation assay, RNA interference, and p53-deficient cells to verify that p21(WAF1/CIP1) induction by ascochlorin is related to transcriptional repression of c-Myc. ascochlorin 145-156 P53 Homo sapiens 82-85 20558137-7 2010 These results suggest that ascochlorin induces G1 arrest via the p53-independent suppression of c-Myc. ascochlorin 27-38 P53 Homo sapiens 65-68 20514393-0 2010 Inhibition of p53 sensitizes MCF-7 cells to ceramide treatment. Ceramides 44-52 P53 Homo sapiens 14-17 20514393-3 2010 Ceramide induced a selective arrest of MCF-7 cells in the G1-phase, which was associated with a decreased expression of cyclins D and E and increased expression of p53 and p21. Ceramides 0-8 P53 Homo sapiens 164-167 20514393-4 2010 Interestingly, inhibition of p53 using pifithrin alpha or RNAi sensitized MCF-7 cells to ceramide-induced cell death. Ceramides 89-97 P53 Homo sapiens 29-32 20514393-6 2010 The increased sensitivity to ceramide, in the context of p53 inhibition, may be due to decreased expression of p21, as siRNA targeted to p21 also sensitized MCF-7 cells to ceramide-induced death. Ceramides 29-37 P53 Homo sapiens 57-60 20514393-7 2010 These data demonstrate that in tumors with inactivating mutations of p53, ceramide-based therapies might provide a novel and effective treatment option. Ceramides 74-82 P53 Homo sapiens 69-72 20587660-5 2010 These results suggest that ascofuranone upregulates p21(WAF1/CIP1) through p53-independent suppression of c-Myc expression, leading to cytostatic G(1) arrest. ascofuranone 27-39 P53 Homo sapiens 75-78 20587660-6 2010 Thus, ascofuranone represents a unique natural antitumor compound that targets c-Myc independent of p53. ascofuranone 6-18 P53 Homo sapiens 100-103 20171194-5 2010 Inhibition of p38 using SB202190 or SB203580 inhibited BEL-induced increases in P-p53 (ser15), p53 and p21, and altered the number of cells in G1 in LNCaP cells, and S-phase in PC-3 cells. SB 203580 36-44 P53 Homo sapiens 82-85 20171194-5 2010 Inhibition of p38 using SB202190 or SB203580 inhibited BEL-induced increases in P-p53 (ser15), p53 and p21, and altered the number of cells in G1 in LNCaP cells, and S-phase in PC-3 cells. SB 203580 36-44 P53 Homo sapiens 95-98 20587334-6 2010 Transient transfection assays indicated that overexpression of LBH or alphaB-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both alphaB-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. alphab-crystallin 70-87 P53 Homo sapiens 294-297 20587334-6 2010 Transient transfection assays indicated that overexpression of LBH or alphaB-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both alphaB-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. alphab-crystallin 180-197 P53 Homo sapiens 130-133 20587334-6 2010 Transient transfection assays indicated that overexpression of LBH or alphaB-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both alphaB-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. alphab-crystallin 180-197 P53 Homo sapiens 294-297 20587334-7 2010 These results showed that the interaction of LBH and alphaB-crystallin may inhibit synergistically the transcriptional regulation of p53 and p21. alphab-crystallin 53-70 P53 Homo sapiens 133-136 20124408-0 2010 SCH529074, a small molecule activator of mutant p53, which binds p53 DNA binding domain (DBD), restores growth-suppressive function to mutant p53 and interrupts HDM2-mediated ubiquitination of wild type p53.

SCH 529074 34-43 P53 Homo sapiens 76-79 19874801-5 2010 In wild-type p53 expressing CML cells MK-0457 sensitivity was modulation by alterations in p53 levels through HDM-2 inhibition and gene silencing. VX680 38-45 P53 Homo sapiens 13-16 19874801-5 2010 In wild-type p53 expressing CML cells MK-0457 sensitivity was modulation by alterations in p53 levels through HDM-2 inhibition and gene silencing.

Panobinostat 47-59 P53 Homo sapiens 7-10 20208142-3 2010 HepG2 (p53wt) and Hep3B (p53null) responded to panobinostat treatment with a reduction of cell proliferation and a significant increase in apoptotic cell death at low micromolar concentrations. Panobinostat 47-59 P53 Homo sapiens 25-28 20557688-9 2010 In conclusion, the release of ROS by PU- or PTFE-treated THP-1 cells may induce iNOS expression and cause apoptosis in HUVECs via the p53, Bax and Bcl-2 proteins. Polytetrafluoroethylene 44-48 P53 Homo sapiens 134-137 20053762-7 2010 This compound abrogates an etoposide-induced G(2) arrest with an IC(50) of 55 nmol/L in HT29 cells, and significantly enhances the cell killing of gemcitabine and SN38 by 3.0- to 29-fold in several colon tumor lines in vitro and in a p53-dependent fashion. gemcitabine 147-158 P53 Homo sapiens 234-237 20228131-0 2010 Cyclophosphamide dose intensification may circumvent anthracycline resistance of p53 mutant breast cancers. Cyclophosphamide 0-16 P53 Homo sapiens 81-84 20228131-7 2010 A sharp statistical interaction was detected between p53 status and cyclophosphamide dose intensity. Cyclophosphamide 68-84 P53 Homo sapiens 53-56 20228131-10 2010 Thus, our data strongly suggest that cyclophosphamide dose intensification in ER(-) p53-mutated breast cancer patients could significantly improve their response. Cyclophosphamide 37-53 P53 Homo sapiens 84-87 20364585-5 2010 RESULTS: Phytic acid treatment significantly inhibited the growth of human gastric cancer cell SGC-7901 and markedly caused their apoptosis following downregulation of P53 protein expression. Phytic Acid 9-20 P53 Homo sapiens 168-171 20364585-6 2010 CONCLUSION: The downregulation of apoptosis relative protein P53 expression was the possible mechanism of phytic acid induced growth inhibition and apoptosis in SGC-7901 cells. Phytic Acid 106-117 P53 Homo sapiens 61-64 20211059-8 2010 NT4-p53(N15)-Ant on HepG2 cells was measured by a colorimetric 3-[4,5-dimethyl thiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. monooxyethylene trimethylolpropane tristearate 126-129 P53 Homo sapiens 4-7 20211059-10 2010 NT4-p53(N15)-Ant and its potential mechanism was detected by light microscopy, electron microscopy, MTT, LDH-release assay and annexin V-PI double staining. monooxyethylene trimethylolpropane tristearate 100-103 P53 Homo sapiens 4-7 19751709-0 2009 Non-dioxin-like-PCBs phosphorylate Mdm2 at Ser166 and attenuate the p53 response in HepG2 cells. Dioxins 4-10 P53 Homo sapiens 68-71 19903850-7 2009 Pursuing these findings, we have determined that imatinib-induced DNA damage is responsible for the increased activity of p53, identifying a novel off-target activity for this drug. Imatinib Mesylate 49-57 P53 Homo sapiens 122-125 19915967-2 2009 In this study, we investigated the effects of lycopene on the oxidative injury and apoptosis of endothelial cells induced by H(2)O(2), and the effects of lycopene on the expression of p53, caspase-3 mRNA in injured cells. Lycopene 154-162 P53 Homo sapiens 184-187 19682442-6 2009 Furthermore, [Ru(terpy)(bpy)Cl]Cl was able to activate the P53-dependent and independent pathways, and induced human hepatoma cells to undergo apoptosis. [ru(terpy)(bpy)cl]cl 13-33 P53 Homo sapiens 59-62 19923910-6 2009 We further show that p53-reporter activity is induced in DLD1 putative cancer stem cell side-populations analyzed by their Hoechst dye efflux properties following treatment with the p53 pathway restoring drug ellipticine. ellipticine 209-220 P53 Homo sapiens 21-24 19923910-6 2009 We further show that p53-reporter activity is induced in DLD1 putative cancer stem cell side-populations analyzed by their Hoechst dye efflux properties following treatment with the p53 pathway restoring drug ellipticine. ellipticine 209-220 P53 Homo sapiens 182-185 19729440-3 2009 We observed ectopic UB outgrowth from the Wolffian duct (WD) in one third of p53(-/-) embryos. BM 20-22 P53 Homo sapiens 77-80 19729440-5 2009 Transgenic expression of dominant negative p53 or conditional inactivation of p53 in the UB but not in the metanephric mesenchyme lineage recapitulated the duplex phenotype.

BM 227-229 P53 Homo sapiens 17-20 19233506-7 2009 Interestingly, both strategies substantially decrease cell survival of MPM cells but the antitumor activity of Decitabine, differently from DNMT1 silencing, is mediated, at least in part, by a p53-independent p21 upregulation, and is characterized by the arrest of MPM cells at the G2/M phase of the cell cycle. Decitabine 111-121 P53 Homo sapiens 193-196 19887545-6 2009 MK-1775 abrogates G(2) DNA damage checkpoint, leading to apoptosis in combination with DNA-damaging chemotherapeutic agents such as gemcitabine, carboplatin, and cisplatin selectively in p53-deficient cells. gemcitabine 132-143 P53 Homo sapiens 187-190 19887545-6 2009 MK-1775 abrogates G(2) DNA damage checkpoint, leading to apoptosis in combination with DNA-damaging chemotherapeutic agents such as gemcitabine, carboplatin, and cisplatin selectively in p53-deficient cells.

Lycopene 85-93 P53 Homo sapiens 139-143 19737941-8 2009 Furthermore, subtoxic concentrations of suberoylanilide hydroxamic acid sensitize two TRAIL resistant human oral cancer cells, SAS and Ca9-22, to exogenous recombinant TRAIL-induced apoptosis in a p53-independent manner. Vorinostat 40-71 P53 Homo sapiens 197-200 19157955-5 2009 Western blot analyses demonstrated that the expression of p21 protein was remarkably augmented and hyperacetylation of p53 was induced after SAHA treatment. Vorinostat 141-145 P53 Homo sapiens 119-122 19533719-1 2009 Flexibility required: We designed intramolecular bipartite tetracysteine sites in loops of p53 and the beta-sheets of EmGFP. tetracysteine 59-72 P53 Homo sapiens 91-94 19584241-4 2009 Here, we show that p53 wild-type NB cells are highly sensitive to SAM486A treatment. 4-amidinoindan-1-one 2'-amidinohydrazone 66-73 P53 Homo sapiens 19-22 19584241-5 2009 Most notably, SAM486A treatment resulted in the rapid accumulation of proapoptotic proteins p53 and Mdm2. 4-amidinoindan-1-one 2'-amidinohydrazone 14-21 P53 Homo sapiens 92-95 19513507-5 2009 Further, tumor suppressor p53 was overexpressed in two arsenic-resistant cell lines, but the levels of p53 mediators MDM2 and gankyrin, which regulate the ubiquitination of p53, increased simultaneously. Arsenic 55-62 P53 Homo sapiens 26-29 19513507-5 2009 Further, tumor suppressor p53 was overexpressed in two arsenic-resistant cell lines, but the levels of p53 mediators MDM2 and gankyrin, which regulate the ubiquitination of p53, increased simultaneously. Arsenic 55-62 P53 Homo sapiens 103-106 19513507-5 2009 Further, tumor suppressor p53 was overexpressed in two arsenic-resistant cell lines, but the levels of p53 mediators MDM2 and gankyrin, which regulate the ubiquitination of p53, increased simultaneously. Arsenic 55-62 P53 Homo sapiens 103-106 19347028-8 2009 Using the property of p53, we can deliver the chemical (propidium iodine) into K-Ras mutated cells selectively. Propidium 56-72 P53 Homo sapiens 22-25 18836721-0 2009 Cytotoxic diarylheptanoid induces cell cycle arrest and apoptosis via increasing ATF3 and stabilizing p53 in SH-SY5Y cells. Diarylheptanoids 10-25 P53 Homo sapiens 102-105 19179467-0 2009 Myc sensitizes p53-deficient cancer cells to the DNA-damaging effects of the DNA methyltransferase inhibitor decitabine. Decitabine 109-119 P53 Homo sapiens 15-18 19265193-2 2009 Here we demonstrate that p53 acetylation at Lys-320/Lys-373/Lys-382 is also required for its transcription-independent functions in BAX activation, reactive oxygen species production, and apoptosis in response to the histone deacetylase inhibitors (HDACi) suberoylanilide hydroxamic acid and LAQ824. Vorinostat 256-287 P53 Homo sapiens 25-28 18951928-5 2009 We show that Zn/PDTC induces p53 proteasomal degradation and that the proteasome inhibitor MG132 further increases fibroblast growth inhibition by Zn/PDTC, suggesting that p53 degradation plays an important role in fibroblast resistance to Zn/PDTC. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 91-96 P53 Homo sapiens 172-175 19176374-1 2009 Inositol hexaphosphate (IP6) causes G(1) arrest and increases cyclin-dependent kinase inhibitors p21/Cip1 and p27/Kip1 protein levels in human prostate cancer (PCa) DU145 cells lacking functional p53. Phytic Acid 0-22 P53 Homo sapiens 196-199 19176374-1 2009 Inositol hexaphosphate (IP6) causes G(1) arrest and increases cyclin-dependent kinase inhibitors p21/Cip1 and p27/Kip1 protein levels in human prostate cancer (PCa) DU145 cells lacking functional p53. Phytic Acid 24-27 P53 Homo sapiens 196-199 19010910-1 2008 While the therapeutic activity of the deoxycytidine analogue decitabine is thought to reflect its ability to reactivate methylation-silenced genes, this agent is also known to trigger p53-dependent DNA damage responses. Decitabine 61-71 P53 Homo sapiens 184-187 19010910-2 2008 Here, we report that p53-inducible ribonucleotide reductase (p53R2/RRM2B) is a robust transcriptional target of decitabine.

Peroxynitrous Acid 4-17 P53 Homo sapiens 184-187 18951438-7 2008 In this article we discuss how LSDBs can accomplish these goals, using existing databases for BRCA1, BRCA2, MSH2, MLH1, TP53, and CDKN2A to illustrate the progress and remaining challenges in this field. lsdbs 31-36 P53 Homo sapiens 120-124 19181008-4 2008 Previously, an animal model was developed by our research group to investigate the expression of three genes c-myc, Ha-ras and p53 as early molecular epidemiological biomarkers of carcinogenic exposure or carcinogenesis caused by DMBA (dimethylbenz[alpha]anthracene). dimethylbenz[alpha]anthracene 236-265 P53 Homo sapiens 127-130 21479491-4 2008 Two representative chemotherapeutic agents for pancreatic cancer, 5-fluorouracil and gemcitabine, promoted cell death in a p53-dependent manner; however, 1% hypoxia caused chemoresistance to these drugs. gemcitabine 85-96 P53 Homo sapiens 123-126 18640142-1 2008 INTRODUCTION: Polymorphisms in p53, p21 and CCND1 could regulate the progression of the cell cycle and might increase the susceptibility to inorganic arsenic-related cancer risk. Arsenic 150-157 P53 Homo sapiens 31-34 18633130-4 2008 We found that MK-0457, which itself activates p53 signaling, acts synergistically with Nutlin-3 to induce apoptosis in wild-type p53 AML cell lines OCI-AML-3 and MOLM-13 but not in p53-null HL-60 cells. VX680 14-21 P53 Homo sapiens 46-49 18633130-4 2008 We found that MK-0457, which itself activates p53 signaling, acts synergistically with Nutlin-3 to induce apoptosis in wild-type p53 AML cell lines OCI-AML-3 and MOLM-13 but not in p53-null HL-60 cells. VX680 14-21 P53 Homo sapiens 129-132 18633130-4 2008 We found that MK-0457, which itself activates p53 signaling, acts synergistically with Nutlin-3 to induce apoptosis in wild-type p53 AML cell lines OCI-AML-3 and MOLM-13 but not in p53-null HL-60 cells. VX680 14-21 P53 Homo sapiens 129-132 18633130-5 2008 MK-0457 and Nutlin-3 showed synergism in inducing p53, conformational change of Bax and Deltapsi(m) loss, suggesting an involvement of p53-mediated mitochondrial apoptosis. VX680 0-7 P53 Homo sapiens 50-53 18633130-5 2008 MK-0457 and Nutlin-3 showed synergism in inducing p53, conformational change of Bax and Deltapsi(m) loss, suggesting an involvement of p53-mediated mitochondrial apoptosis. VX680 0-7 P53 Homo sapiens 135-138 18708766-4 2008 DP, TSA and SAHA inhibited Aurora A, Aurora B and survivin expression with kinetics that were remarkably similar within individual cell lines, and appeared to coincide with p53 expression status. dp 0-2 P53 Homo sapiens 173-176 18458532-3 2008 Cells with differing p53 genotype showed susceptibility to FNQ. napabucasin 59-62 P53 Homo sapiens 21-24 18458532-4 2008 However, this response was attenuated in those overexpressing mutant p53, although a brief p53 induction was early seen in FNQ-treated wt p53 cells. napabucasin 123-126 P53 Homo sapiens 91-94 18458532-4 2008 However, this response was attenuated in those overexpressing mutant p53, although a brief p53 induction was early seen in FNQ-treated wt p53 cells. napabucasin 123-126 P53 Homo sapiens 91-94 18704310-11 2008 SB203580 significantly increased the level of cellular phosphorylated p53 protein, but decreased the p-gp protein level and MDR1 mRNA level in A2780/Taxol cells. SB 203580 0-8 P53 Homo sapiens 70-73 18723490-4 2008 We previously identified a family of small molecules (HLI98s, 7-nitro-10-aryl-5-deazaflavins) that inhibit the E3 activity of Hdm2, increase cellular p53, and selectively kill transformed cells expressing wild-type p53. 7-nitro-10-aryl-5-deazaflavins 62-92 P53 Homo sapiens 150-153 18723490-4 2008 We previously identified a family of small molecules (HLI98s, 7-nitro-10-aryl-5-deazaflavins) that inhibit the E3 activity of Hdm2, increase cellular p53, and selectively kill transformed cells expressing wild-type p53. 7-nitro-10-aryl-5-deazaflavins 62-92 P53 Homo sapiens 215-218 18325917-2 2008 We analysed the efficacy of a preoperative combination between 5-fluorouracil, anthracyclines and cyclophosphamide according to both p53 status and molecular classification. Cyclophosphamide 98-114 P53 Homo sapiens 133-136 21783897-0 2008 Suppression of zinc-induced p53 phosphorylation and p21 expression by wortmannin in A549 human pulmonary epithelial cells. Wortmannin 70-80 P53 Homo sapiens 28-31 21783897-2 2008 Treatment with wortmannin, an inhibitor of phosphatidylinositol 3-kinase (PI3K)-related kinases, suppressed ZnSO(4)-induced phosphorylation and accumulation of p53 protein. Wortmannin 15-25 P53 Homo sapiens 160-163 21783897-3 2008 Expression of cyclin-dependent kinase inhibitor p21, one of the genes regulated by p53, was up-regulated following exposure to ZnSO(4), and suppressed by preincubation with wortmannin.

Tetrachloroethylene 50-54 P53 Homo sapiens 129-132 12160929-4 2002 The results showed that exposure to vapor TCE and PERC produced a dose-dependent and more pronounced accumulation of H(2)O(2) in p53-WT H460 than p53-null H1299 cells. Tetrachloroethylene 50-54 P53 Homo sapiens 146-149 12160929-6 2002 Cotreatment of p53-WT H460 cells with free radical scavengers, such as D-mannitol, uric acid, and sodium selenite, significantly attenuated the TCE- or PERC-induced lipid peroxidation. Tetrachloroethylene 152-156 P53 Homo sapiens 15-18 12160929-7 2002 In contrast, depletion of GSH in p53-null H1299 cells enhanced TCE- or PERC-induced lipid peroxidation. Tetrachloroethylene 71-75 P53 Homo sapiens 33-36 12071847-9 2002 This phosphorylation was associated with an SB203580-sensitive accumulation of p53, even in the presence of a serine phosphatase inhibitor. SB 203580 44-52 P53 Homo sapiens 79-82 12416024-11 2002 We also observed that p53 status influenced correlations between ENT1 transporter gene RNA levels and sensitivity to the drugs tiazafurin, AZQ and 3-deazauridine. 3-Deazauridine 147-161 P53 Homo sapiens 22-25 12067251-8 2002 Treatment of p53 cDNA with micromolar concentrations of (+/-)-anti-7,8-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene, (anti-BPDE, an ultimate carcinogen) or sub-micromolar concentrations of BP-7,8-dione in the presence of redox-cycling conditions (NADPH and CuCl(2)) also caused p53 mutations in a dose-dependent manner. (+/-)-anti-7,8-dihydroxy-9alpha 56-87 P53 Homo sapiens 13-16 12067251-8 2002 Treatment of p53 cDNA with micromolar concentrations of (+/-)-anti-7,8-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene, (anti-BPDE, an ultimate carcinogen) or sub-micromolar concentrations of BP-7,8-dione in the presence of redox-cycling conditions (NADPH and CuCl(2)) also caused p53 mutations in a dose-dependent manner. anti 62-66 P53 Homo sapiens 13-16 12067251-8 2002 Treatment of p53 cDNA with micromolar concentrations of (+/-)-anti-7,8-dihydroxy-9alpha,10alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene, (anti-BPDE, an ultimate carcinogen) or sub-micromolar concentrations of BP-7,8-dione in the presence of redox-cycling conditions (NADPH and CuCl(2)) also caused p53 mutations in a dose-dependent manner. anti 62-66 P53 Homo sapiens 299-302 12131661-5 2002 Butyrate reduced mutant p53 expression, whereas aspirin did not affect p53 expression. Butyrates 0-8 P53 Homo sapiens 24-27 12048682-2 2002 METHODS: Recombinant eukaryotic expression vector pcDNA3 containing full-length human wild-type p53 cDNA was introduced by lipofectamine-mediated gene transfection into SKOV-3 cultured cells which were acted on by cisplatin of different concentrations. Lipofectamine 123-136 P53 Homo sapiens 96-99 12010862-0 2002 XRCC1 and CYP2E1 polymorphisms as susceptibility factors of plasma mutant p53 protein and anti-p53 antibody expression in vinyl chloride monomer-exposed polyvinyl chloride workers. Vinyl Chloride 122-136 P53 Homo sapiens 74-77 12010862-2 2002 Plasma mutant p53 protein and anti-p53 antibody have also been associated with vinyl chloride monomer (VCM) exposure, although the mechanism of VCM-related carcinogenesis remains unclear. Vinyl Chloride 79-93 P53 Homo sapiens 14-17 12010862-2 2002 Plasma mutant p53 protein and anti-p53 antibody have also been associated with vinyl chloride monomer (VCM) exposure, although the mechanism of VCM-related carcinogenesis remains unclear. Vinyl Chloride 79-93 P53 Homo sapiens 35-38 11960374-0 2002 P53 mediates ceramide-induced apoptosis in SKN-SH cells. Ceramides 13-21 P53 Homo sapiens 0-3 11960374-4 2002 Ceramide-induced apoptosis is accompanied by accumulation of p53 followed by an increase of Bax and decrease of Bcl-2 levels. Ceramides 0-8 P53 Homo sapiens 61-64 11960374-7 2002 These results suggest that p53 regulates the ratio Bcl-2/Bax and the expression/activation of caspases during ceramide-induced apoptosis in SKN-SH cells. Ceramides 110-118 P53 Homo sapiens 27-30 11960374-9 2002 Thus ceramide-induced reduction in the Bcl-2/Bax ratio, increase in caspase activity, and apoptosis is dependent upon increases in cellular p53 levels which play a critical role in the regulation of apoptotic cell death. Ceramides 5-13 P53 Homo sapiens 140-143 21315017-11 2002 Mutated p53 protein in parent cell line 801D was positive and in PEGFP-p53(AS)-801D was negative with immunochemical stain. Arsenic 75-77 P53 Homo sapiens 71-74 11862428-5 2002 Functionality of the p53 pathway was evaluated by incubating cells with carboplatin or doxorubicin and monitoring the effects on the levels of the p53, p21(WAF1/CIP1), and MDM 2 proteins by Western blot analyses. Carboplatin 72-83 P53 Homo sapiens 21-24 11802204-11 2002 This corresponded with suppression of Bcl-2 and Bcl-X/L expression in wt-p53 cells exposed to gemcitabine whereas Bcl-2 levels remained stable and Bcl-X/L levels increased in mut-p53 cells exposed to gemcitabine. gemcitabine 94-105 P53 Homo sapiens 73-76 11802204-12 2002 We conclude that the p53 status of cancer cells influences their sensitivity to gemcitabine cytotoxicity. gemcitabine 80-91 P53 Homo sapiens 21-24 11802204-13 2002 Our evidence suggests that loss of p53 function leads to loss of cell cycle control and alterations in the apoptotic cascade, conferring resistance to gemcitabine in cancer cell lines displaying a mut-p53. gemcitabine 151-162 P53 Homo sapiens 35-38 11802204-13 2002 Our evidence suggests that loss of p53 function leads to loss of cell cycle control and alterations in the apoptotic cascade, conferring resistance to gemcitabine in cancer cell lines displaying a mut-p53. gemcitabine 151-162 P53 Homo sapiens 201-204 11802206-0 2002 P53 overexpression predicts poor chemosensitivity to high-dose 5-fluorouracil plus leucovorin chemotherapy for stage IV colorectal cancers after palliative bowel resection. Leucovorin 83-93 P53 Homo sapiens 0-3 11840331-4 2002 This p53wt diminution was dependent on proteasome activity, as inhibited by MG-132 inhibitor. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 76-82 P53 Homo sapiens 5-8 11782540-5 2002 The fluorescein-labeled peptide, FL-CDB3, binds wild-type p53 core domain with a dissociation constant of 0.5 microM, and raises the apparent melting temperatures of wild-type and a representative oncogenic mutant, R249S core domain. Fluorescein 4-15 P53 Homo sapiens 58-61 11706017-0 2002 Mechanism of p53-dependent apoptosis induced by 3-methylcholanthrene: involvement of p53 phosphorylation and p38 MAPK. Methylcholanthrene 48-68 P53 Homo sapiens 13-16 11706017-0 2002 Mechanism of p53-dependent apoptosis induced by 3-methylcholanthrene: involvement of p53 phosphorylation and p38 MAPK. Methylcholanthrene 48-68 P53 Homo sapiens 85-88 11706017-3 2002 MC induced apoptosis, preceded by serine 15 phosphorylation and accumulation of p53. Methylcholanthrene 0-2 P53 Homo sapiens 80-83 11706017-4 2002 MC failed to cause apoptosis in p53-deficient MG63 cells, whereas ectopic expression of p53 in MG63 cells restored the response to MC. Methylcholanthrene 131-133 P53 Homo sapiens 88-91 11706017-5 2002 Therefore, MC-induced apoptosis was dependent on p53. Methylcholanthrene 11-13 P53 Homo sapiens 49-52 11859874-4 2002 This study examined if mutations in the tumor suppressor gene p53 affected organochlorine exposure related breast cancer risk and survival. Hydrocarbons, Chlorinated 75-89 P53 Homo sapiens 62-65 11859874-12 2002 These preliminary results suggest that p53 mutations may have a modifying effect on at least the breast cancer risk associated with exposures to organochlorines. Hydrocarbons, Chlorinated 145-160 P53 Homo sapiens 39-42 12174820-1 2002 CP-31398, a styrylquinazoline, emerged from a screen for therapeutic agents that restore a wild-type DNA-binding conformation of mutant p53 to suppress tumors in-vivo (Science 286, 2507, 1999). styrylquinazoline 12-29 P53 Homo sapiens 136-139 12599424-2 2002 METHODS: Recombinant eukaryotic expression vector pCB6.p53 containing human wild-type p53 cDNA was introduced by lipofectamine transfection regent into HeLa cell line. Lipofectamine 113-126 P53 Homo sapiens 55-58 12658781-4 2002 MTT showed that p53 gene by itself induced strong inhibition effect on the growth of U251 cells [inhibition rate, IR (79.60 +/- 5.69)%]. monooxyethylene trimethylolpropane tristearate 0-3 P53 Homo sapiens 16-19 11594730-0 2001 Evidence for peroxynitrite-mediated modifications to p53 in human gliomas: possible functional consequences. Peroxynitrous Acid 13-26 P53 Homo sapiens 53-56 11594730-3 2001 Furthermore, we show that p53, a key tumor suppressor protein, has evidence of peroxynitrite-mediated modifications in gliomas in vivo. Peroxynitrous Acid 79-92 P53 Homo sapiens 26-29 11594730-4 2001 Experiments in vitro demonstrate that peroxynitrite treatment of recombinant wild-type p53 at physiological concentrations results in formation of higher molecular weight aggregates, tyrosine nitration, and loss of specific DNA binding. Peroxynitrous Acid 38-51 P53 Homo sapiens 87-90 11594730-5 2001 Peroxynitrite treatment of human glioma cell lysates similarly resulted in selective tyrosine nitration of p53 and was also associated with loss of p53 DNA binding ability. Peroxynitrous Acid 0-13 P53 Homo sapiens 107-110 11594730-5 2001 Peroxynitrite treatment of human glioma cell lysates similarly resulted in selective tyrosine nitration of p53 and was also associated with loss of p53 DNA binding ability. Peroxynitrous Acid 0-13 P53 Homo sapiens 148-151 11594730-6 2001 These data indicate that tyrosine nitration of proteins occurs in human gliomas in vivo, that p53 may be a target of peroxynitrite in these tumors, and that physiological concentrations of peroxynitrite can result in a loss of p53 DNA binding ability in vitro. Peroxynitrous Acid 117-130 P53 Homo sapiens 94-97 11594730-6 2001 These data indicate that tyrosine nitration of proteins occurs in human gliomas in vivo, that p53 may be a target of peroxynitrite in these tumors, and that physiological concentrations of peroxynitrite can result in a loss of p53 DNA binding ability in vitro. Peroxynitrous Acid 189-202 P53 Homo sapiens 227-230 11594730-7 2001 These findings raise the possibility that peroxynitrite may contribute to loss of wild-type p53 functional activity in gliomas by posttranslational protein modifications. Peroxynitrous Acid 42-55 P53 Homo sapiens 92-95 11498784-5 2001 Sucrose gradient experiments showed that p53 blocks translation initiation by preventing 80S ribosome formation on an mRNA bearing the FGF-2 mRNA leader sequence. Sucrose 0-7 P53 Homo sapiens 41-44 11384212-6 2001 However, lung H441 adenocarcinoma cells, with a mutation in exon 5, codon 158 of p53, exhibited partial G1 arrest after the diol epoxides as well as actinomycin D, and H2030 adenocarcinoma cells did not show G1 arrest after any of the chemicals despite a normal p53. diol epoxides 124-137 P53 Homo sapiens 81-84 11329373-4 2001 Immunocytochemistry of fixed human fibroblasts treated with either UV light, the kinase and transcription inhibitor DRB or the proteasome inhibitor MG132 revealed abundant p53 localized to the nucleus. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 148-153 P53 Homo sapiens 172-175 11329373-6 2001 However, in cells treated with MG132, residual p53 localized to distinct large foci. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 31-36 P53 Homo sapiens 47-50 11302731-5 2001 On the other hand, treatment with wortmannin or caffeine suppressed CdCl(2)-induced Ser 15 phosphorylation and accumulation of p53 protein. Wortmannin 34-44 P53 Homo sapiens 127-130 11302731-5 2001 On the other hand, treatment with wortmannin or caffeine suppressed CdCl(2)-induced Ser 15 phosphorylation and accumulation of p53 protein. Cadmium Chloride 68-75 P53 Homo sapiens 127-130 21044462-2 2001 METHODS: Vectors of three kinds of p53 minigene were transfected into p53-null H1299 cells through lipofectAMINE. Lipofectamine 99-112 P53 Homo sapiens 35-38 21044462-2 2001 METHODS: Vectors of three kinds of p53 minigene were transfected into p53-null H1299 cells through lipofectAMINE. Lipofectamine 99-112 P53 Homo sapiens 70-73 11287297-9 2001 Furthermore, a DNA damage- and oxidative stress-dependent protein, P53, could also been induced by CuQ treatments in a time-course and dose-dependent manners. bis(8-quinolinolato)copper(II) 99-102 P53 Homo sapiens 67-70 11287297-11 2001 In conclusion, our current study strongly suggests that CuQ induces gene mutation, global DNA damage, and P53 expression through a ROS-dependent mechanism. bis(8-quinolinolato)copper(II) 56-59 P53 Homo sapiens 106-109 11275476-2 2001 We investigated the ability of an aromatic amine, 4-aminobiphenyl (4-ABP) and its N-hydroxy metabolite (4-ABP(NHOH)) to cause oxidative DNA damage, using (32)P-labeled human DNA fragments from the p53 tumor suppressor gene and the c-Ha-ras-1 protooncogene. aromatic amine 34-48 P53 Homo sapiens 197-200 11259619-0 2001 Activation of the p53 DNA damage response pathway after inhibition of DNA methyltransferase by 5-aza-2"-deoxycytidine. Decitabine 95-117 P53 Homo sapiens 18-21 11313880-8 2001 Moreover, expression of functional p53 protein in glioma cells expressing mutant p53 using a temperature-sensitive human p53(Val138) induced ceramide accumulation by the activation of neutral sphingomyelinase which was dependent on the generation of O2-*. Ceramides 141-149 P53 Homo sapiens 35-38 11313880-8 2001 Moreover, expression of functional p53 protein in glioma cells expressing mutant p53 using a temperature-sensitive human p53(Val138) induced ceramide accumulation by the activation of neutral sphingomyelinase which was dependent on the generation of O2-*. Ceramides 141-149 P53 Homo sapiens 81-84 11313880-8 2001 Moreover, expression of functional p53 protein in glioma cells expressing mutant p53 using a temperature-sensitive human p53(Val138) induced ceramide accumulation by the activation of neutral sphingomyelinase which was dependent on the generation of O2-*. Ceramides 141-149 P53 Homo sapiens 81-84 11313880-9 2001 Taken together, these results suggest that p53 may modulate ceramide generation by activation of neutral sphingomyelinase through the formation of O2-*, but not its downstream compounds H2O2 or * OH. Ceramides 60-68 P53 Homo sapiens 43-46 12733349-5 2001 MTT colorimetric assay, TUNEL fluorenscence microscopy and flow cytometry showed that foreign bax or p53 gene inhibited the LCC growth and induced apoptosis (23.9% and 26.1% of inhibitory rate by bax gene and p53 plus bax genes respectively). monooxyethylene trimethylolpropane tristearate 0-3 P53 Homo sapiens 101-104 11223405-2 2001 We have investigated sequence specificity of oxidative stress-mediated DNA damage by using 32P-labeled DNA fragments obtained from the human c-Ha-ras-1 and p53 genes. Phosphorus-32 91-94 P53 Homo sapiens 156-159 11053443-0 2001 A role for the polyproline domain of p53 in its regulation by Mdm2. polyproline 15-26 P53 Homo sapiens 37-40 11053443-3 2001 p53 protein lacking the polyproline region has impaired apoptotic activity and altered specificity for certain apoptotic target genes. polyproline 24-35 P53 Homo sapiens 0-3 11053443-5 2001 p53 lacking the polyproline region was identified to be more susceptible to inhibition by Mdm2. polyproline 16-27 P53 Homo sapiens 0-3 11053443-7 2001 This increased sensitivity to Mdm2 results from an enhanced affinity of Mdm2 toward p53 lacking the polyproline region. polyproline 100-111 P53 Homo sapiens 84-87 11053443-9 2001 The polyproline region is proposed to be important in the modulation of the inhibitory effects of Mdm2 on p53 activities and stability. polyproline 4-15 P53 Homo sapiens 106-109 11158590-2 2001 We have examined the response to p53 when DNA synthesis is blocked by hydroxyurea (HU) or aphidicolin or when DNA is damaged by gamma IR. Aphidicolin 90-101 P53 Homo sapiens 33-36 11158590-5 2001 Moreover, the p53 response to gamma IR is inhibited by pretreatment of cells with HU or aphidicolin, suggesting that blocked DNA replication prevents p53 from being fully active as a transcription factor. Aphidicolin 88-99 P53 Homo sapiens 14-17 11158590-5 2001 Moreover, the p53 response to gamma IR is inhibited by pretreatment of cells with HU or aphidicolin, suggesting that blocked DNA replication prevents p53 from being fully active as a transcription factor. Aphidicolin 88-99 P53 Homo sapiens 150-153 11158615-6 2001 This reduction was prevented by the proteasome inhibitors MG132 and lactacystin, suggesting enhanced p53 degradation in the presence of dicoumarol. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 58-63 P53 Homo sapiens 101-104 11125034-7 2001 Notably, when MDM2 expression is inhibited in S-type cells, with a phosphorothioated antisense oligonucleotide (AS5), then p53 accumulates in the nucleus and the SH-EP1 cells undergo apoptosis. phosphorothioated 67-84 P53 Homo sapiens 123-126 11106681-10 2000 CONCLUSIONS: Combinations of 4-HPR and modulators of ceramide metabolism may form the basis for a novel chemotherapy that is functional under hypoxic conditions (e.g., such as those within tumors) and is p53 independent and caspase independent. Ceramides 53-61 P53 Homo sapiens 204-207 11082419-0 2000 Roles of nuclear factor-kappaB, p53, and p21/WAF1 in daunomycin-induced cell cycle arrest and apoptosis. Daunorubicin 53-63 P53 Homo sapiens 32-35 11082419-1 2000 Daunomycin is a potent inducer of p53 and NF-kappaB transcription factors. Daunorubicin 0-10 P53 Homo sapiens 34-37 11082419-5 2000 However, using different tumor cell lines where p53 or NF-kappaB was inactive, we showed that p21 activation and cell cycle arrest induced by daunomycin was p53-dependent and NF-kappaB-independent, whereas daunomycin-induced apoptosis was p53- and NF-kappaB-independent. Daunorubicin 142-152 P53 Homo sapiens 48-51 11082419-5 2000 However, using different tumor cell lines where p53 or NF-kappaB was inactive, we showed that p21 activation and cell cycle arrest induced by daunomycin was p53-dependent and NF-kappaB-independent, whereas daunomycin-induced apoptosis was p53- and NF-kappaB-independent. Daunorubicin 142-152 P53 Homo sapiens 157-160 11082419-5 2000 However, using different tumor cell lines where p53 or NF-kappaB was inactive, we showed that p21 activation and cell cycle arrest induced by daunomycin was p53-dependent and NF-kappaB-independent, whereas daunomycin-induced apoptosis was p53- and NF-kappaB-independent. Daunorubicin 142-152 P53 Homo sapiens 157-160 11094173-14 2000 There could be a p53-dependent apoptotic pathway in butyrate-induced differentiated Y-79 cells due to the inability to regulate cell cycling. Butyrates 52-60 P53 Homo sapiens 17-20 11798837-9 2000 CONCLUSION: After introduced into GLC-82 cells, Ad-p53 shows enhanced therapeutic efficiency for GLC-82 cells when combined with CDDP or As(2)O(3). Arsenic 137-139 P53 Homo sapiens 51-54 10856831-6 2000 Exposure to AFB1-8, 9-epoxide alone induces a low frequency of AGG to AGT mutation in codon 249 of the p53 gene, as determined by an allele-specific polymerase chain reaction (AS-PCR) assay. aflatoxin B1-2,3-oxide 12-29 P53 Homo sapiens 103-106 10845425-2 2000 A calpain inhibitor, n-acetyl-leu-leu-norleucinal (calpain inhibitor 1), was assessed for ability to enhance p53-dependent apoptosis in human tumor cell lines with endogenous wild-type p53 and in altered p53 cell lines with the replacement of wild-type p53 by a recombinant adenovirus (rAd-p53). n-acetyl-leu-leu 21-37 P53 Homo sapiens 109-112 10866285-1 2000 PURPOSE: This study tests the hypothesis that p53 status, i.e. wild type versus mutant form, is a determinant in radiation protection of human glioma cells by WR-1065, the active thiol form of amifostine (WR-2721). Amifostine 193-203 P53 Homo sapiens 46-49 10699891-0 2000 p53 mutation pattern in hepatocellular carcinoma in workers exposed to vinyl chloride. Vinyl Chloride 71-85 P53 Homo sapiens 0-3 10779915-4 2000 Similar effects were observed upon transduction of the p53-GSE22 genetic suppressor element, known to reduce p53 transcriptional activity. gse22 59-64 P53 Homo sapiens 55-58 10779915-4 2000 Similar effects were observed upon transduction of the p53-GSE22 genetic suppressor element, known to reduce p53 transcriptional activity. gse22 59-64 P53 Homo sapiens 109-112 10874474-0 2000 Induction of p53-independent p21 during ceramide-induced G1 arrest in human hepatocarcinoma cells. Ceramides 40-48 P53 Homo sapiens 13-16 10874474-6 2000 p21 induction was also observed in the Hep3B cells lacking a functional p53 after exposure to ceramide. Ceramides 94-102 P53 Homo sapiens 72-75 10874474-11 2000 Together, these results suggest that p21, induced through p53-independent pathway, participates in the induction of pRb dephosphorylation by inhibiting cdk2 activity during ceramide-mediated G1 arrest in hepatocarcinoma cells. Ceramides 173-181 P53 Homo sapiens 58-61 10585263-3 1999 Previously, we reported that p21 was induced in a p53-independent manner during ceramide-induced apoptosis in human hepatocarcinoma cell lines. Ceramides 80-88 P53 Homo sapiens 50-53 10632350-2 1999 Overexpression of the p53 protein was present in 49% of the samples studied with CM1, 18% with PAb1801, 30% with DO7, and 44% with DO7. [(2S,3S,4S,5R,6S)-6-methoxy-3,4,5-tris(oxidanyl)oxan-2-yl]methanesulfonic acid 113-116 P53 Homo sapiens 22-25 10632350-2 1999 Overexpression of the p53 protein was present in 49% of the samples studied with CM1, 18% with PAb1801, 30% with DO7, and 44% with DO7. [(2S,3S,4S,5R,6S)-6-methoxy-3,4,5-tris(oxidanyl)oxan-2-yl]methanesulfonic acid 131-134 P53 Homo sapiens 22-25 10597302-0 1999 Induction of apoptosis in U937 human leukemia cells by suberoylanilide hydroxamic acid (SAHA) proceeds through pathways that are regulated by Bcl-2/Bcl-XL, c-Jun, and p21CIP1, but independent of p53. Vorinostat 55-86 P53 Homo sapiens 195-198 10597302-0 1999 Induction of apoptosis in U937 human leukemia cells by suberoylanilide hydroxamic acid (SAHA) proceeds through pathways that are regulated by Bcl-2/Bcl-XL, c-Jun, and p21CIP1, but independent of p53. Vorinostat 88-92 P53 Homo sapiens 195-198 10597302-9 1999 These findings indicate that SAHA potently induces apoptosis in human leukemia cells via a pathway that is p53-independent but at least partially regulated by Bcl-2/Bcl-XL, p21CIP1, and the c-Jun/AP-1 signaling cascade. Vorinostat 29-33 P53 Homo sapiens 107-110 10544021-5 1999 Activation of p53 was accompanied by phosphorylation of p53 at Ser-15 and elevated p21 and MDM2, both of which were at least partly blocked by wortmannin, a kinase inhibitor against proteins with a PI3 kinase domain. Wortmannin 143-153 P53 Homo sapiens 14-17 10544021-5 1999 Activation of p53 was accompanied by phosphorylation of p53 at Ser-15 and elevated p21 and MDM2, both of which were at least partly blocked by wortmannin, a kinase inhibitor against proteins with a PI3 kinase domain. Wortmannin 143-153 P53 Homo sapiens 56-59 10576651-5 1999 Wortmannin-treated cultures display a diminished capacity for radiation-induced up-regulation of p53 protein and expression of p21WAF1, a p53-regulated gene involved in cell cycle arrest at the G1/S border; the treated cultures also exhibit decreased capacity for enhancement of CaMKII activity post-irradiation, known to be necessary for triggering the S phase checkpoint. Wortmannin 0-10 P53 Homo sapiens 97-100 10576651-5 1999 Wortmannin-treated cultures display a diminished capacity for radiation-induced up-regulation of p53 protein and expression of p21WAF1, a p53-regulated gene involved in cell cycle arrest at the G1/S border; the treated cultures also exhibit decreased capacity for enhancement of CaMKII activity post-irradiation, known to be necessary for triggering the S phase checkpoint. Wortmannin 0-10 P53 Homo sapiens 138-141 10473588-5 1999 We show that both recombinant and endogenous forms of p53 specifically interact with KIX. kix 85-88 P53 Homo sapiens 54-57 10393722-14 1999 IMPLICATIONS: 4-HPR may form the basis for a novel, p53-independent chemotherapy that operates through increased intracellular levels of ceramide and that retains cytotoxicity under reduced oxygen conditions. Ceramides 137-145 P53 Homo sapiens 52-55 10391688-3 1999 Not surprisingly, therefore, p53 has been intensively studied by 32P metabolic labelling. Phosphorus-32 65-68 P53 Homo sapiens 29-32 10391688-5 1999 These data demonstrate for the first time that 32P labelling is sufficient to induce a biologically-significant, p53-mediated cellular response and strongly suggest that it perturbs the phosphorylation state of p53 which it is being used to measure. Phosphorus-32 47-50 P53 Homo sapiens 113-116 10391688-5 1999 These data demonstrate for the first time that 32P labelling is sufficient to induce a biologically-significant, p53-mediated cellular response and strongly suggest that it perturbs the phosphorylation state of p53 which it is being used to measure. Phosphorus-32 47-50 P53 Homo sapiens 211-214 10415582-2 1999 The cells were originally derived from a human liver biopsy and immortalized through lipofectamine-mediated transfection of albumin-promotor-regulated antisense constructions against the negative controlling cell cycle proteins Rb and p53 (pAlb asRb, pAIb asp53). Lipofectamine 85-98 P53 Homo sapiens 235-238 10362106-6 1999 PNU 151807, like tallimustine, is able to induce an activation of p53, and consequently of p21 and BAX in a human ovarian cancer cell line (A2780) expressing wild-type p53. tallimustine 17-29 P53 Homo sapiens 66-69 10341297-3 1999 In this study, we investigated the molecular mechanisms by which auristatin-PE, a newly developed experimental agent, and gemcitabine, a commercially available anti-cancer agent, exert their inhibitory effects on pancreatic cancer cell lines containing wild-type p53 (HPAC) and mutant p53 (PANC-1). gemcitabine 122-133 P53 Homo sapiens 263-266 10390705-0 1999 Plasma p53 protein and anti-p53 antibody expression in vinyl chloride monomer workers in Taiwan.

Cyclophosphamide 203-219 P53 Homo sapiens 21-24 10360645-0 1999 Ceramide triggers p53-dependent apoptosis in genetically defined fibrosarcoma tumour cells. Ceramides 0-8 P53 Homo sapiens 18-21 10360645-8 1999 These results suggest that ceramide-induced apoptosis in tumour cells can be dependent on the status of p53 and imply that p53 is also important for stress-induced apoptotic signal transduction cascades generated at the plasma membrane. Ceramides 27-35 P53 Homo sapiens 104-107 10360645-8 1999 These results suggest that ceramide-induced apoptosis in tumour cells can be dependent on the status of p53 and imply that p53 is also important for stress-induced apoptotic signal transduction cascades generated at the plasma membrane. Ceramides 27-35 P53 Homo sapiens 123-126 10334203-5 1999 Using 32P-5"-end-labeled DNA fragments obtained from human p53 tumor suppressor gene and c-Ha-ras-1 protooncogene, we showed that PBQ plus NADH, and also PHQ, induced DNA damage frequently at thymine residues, in the presence of Cu(II). phenylbenzoquinone 130-133 P53 Homo sapiens 59-62 10100719-0 1999 Expression of p53 in cisplatin-resistant ovarian cancer cell lines: modulation with the novel platinum analogue (1R, 2R-diaminocyclohexane)(trans-diacetato)(dichloro)-platinum(IV). 1R,2R-diaminocyclohexane 113-138 P53 Homo sapiens 14-17 10100719-0 1999 Expression of p53 in cisplatin-resistant ovarian cancer cell lines: modulation with the novel platinum analogue (1R, 2R-diaminocyclohexane)(trans-diacetato)(dichloro)-platinum(IV). trans-diacetato) 140-156 P53 Homo sapiens 14-17 10190788-4 1999 Studies of the p53 gene sequence of ovarian tumors at diagnosis suggest that p53 mutations are a potent predictor of response to subsequent treatment with carboplatin. Carboplatin 155-166 P53 Homo sapiens 15-18 10190788-4 1999 Studies of the p53 gene sequence of ovarian tumors at diagnosis suggest that p53 mutations are a potent predictor of response to subsequent treatment with carboplatin. Carboplatin 155-166 P53 Homo sapiens 77-80 9879988-7 1998 Moreover, 3AB but not its analog inhibited irradiation-induced activation of sequence-specific DNA binding of wtp53 as detected using 32P-labeled or biotin-labeled p53 consensus sequence (p53CON). Phosphorus-32 134-137 P53 Homo sapiens 112-115 9951689-4 1998 Chemosensitivity data, according to a short-term assay (FMCA), indicated that tumours with p53 mutation were more resistant to cisplatin and cyclophosphamide. Cyclophosphamide 141-157 P53 Homo sapiens 91-94 9769393-6 1998 On the other hand, an A to G substitution at codon 170 in exon 5 of p53 gene resulting in glutamic acid (ACG) to glycine (GCG) was detected in the DNA of her tongue cancer. gallocatechin gallate 122-125 P53 Homo sapiens 68-71 9683832-5 1998 The degree of DCsI of tumors with expression of p53 (19/mm2, n=50) was significantly lower than that of DCsI in 38 tumors without expression of p53 (27/mm2, P=0.0411). dcsi 14-18 P53 Homo sapiens 48-51 9703286-0 1998 Therapy effect of either paclitaxel or cyclophosphamide combination treatment in patients with epithelial ovarian cancer and relation to TP53 gene status.

Ceramides 14-22 P53 Homo sapiens 0-3 9664074-4 1998 In this study, we investigated the relationship between p53 and ceramide. Ceramides 64-72 P53 Homo sapiens 56-59 9664074-6 1998 In these cells, p53 activation was followed by a dose- and time-dependent increase in endogenous ceramide levels which was not seen in cells lacking functional p53 and treated similarly. Ceramides 97-105 P53 Homo sapiens 16-19 9664074-8 1998 However, in p53-independent systems, such as growth suppression induced by TNF-alpha or serum deprivation, ceramide accumulated irrespective of the upregulation of p53, indicating that p53 regulates ceramide accumulation in only a subset of growth-suppressive pathways. Ceramides 107-115 P53 Homo sapiens 12-15 9664074-10 1998 Also, when cells lacking functional p53, either due to mutation or the expression of the E6 protein of human papilloma virus, were treated with exogenous ceramide, there was equal growth suppression, cell cycle arrest, and apoptosis as compared with cells expressing normal p53. Ceramides 154-162 P53 Homo sapiens 36-39 9664074-10 1998 Also, when cells lacking functional p53, either due to mutation or the expression of the E6 protein of human papilloma virus, were treated with exogenous ceramide, there was equal growth suppression, cell cycle arrest, and apoptosis as compared with cells expressing normal p53. Ceramides 154-162 P53 Homo sapiens 274-277 9664074-12 1998 Instead, they suggest that, in situations where p53 performs a critical regulatory role, such as the response to genotoxic stress, it functions "upstream" of ceramide. Ceramides 158-166 P53 Homo sapiens 48-51 9661637-4 1998 BHT-101 and KAT-4 cells had mutant p53. Butylated Hydroxytoluene 0-3 P53 Homo sapiens 35-38 9661637-10 1998 BHT-101 cells were most sensitive to killing by Ad-p53, with an IC50 of less than 2 multiplicity of infection; SW-1736 cells were intermediate in sensitivity; KAT-4 cells were resistant. Butylated Hydroxytoluene 0-3 P53 Homo sapiens 51-54 9618491-4 1998 We show that concomitant with growth arrest, butyrate induces p21 mRNA expression in an immediate-early fashion, through transactivation of a promoter cis-element(s) located within 1.4 kb of the transcriptional start site, independent of p53 binding. Butyrates 45-53 P53 Homo sapiens 238-241 9649136-2 1998 Here, we examined the effects of wild-type and mutated p53 (143 Val-Ala) on tumorigenic and metastatic potential of two human melanoma cell lines. H-VAL-ALA-OH 64-71 P53 Homo sapiens 55-58 9636999-1 1998 We tested the hypothesis that the instability of the trinucleotide CTG at the myotonic dystrophy (DM) locus could be an intrinsic DNA damage recognisable by the p53 cell-cycle checkpoint system. ctg 67-70 P53 Homo sapiens 161-164 9636999-4 1998 However, in the cells treated with adryamicin, p53 protein levels were comparable in DM and control cells. adryamicin 35-45 P53 Homo sapiens 47-50 9677462-5 1998 Molecular analysis of the same specimen showed mutations of the p53 gene in 13.3% of OLs and 9, 6% of OSCCs. N-biotin-C-Co4(mu3-O)4(Py)4(H2O)4-beta-alanine 85-88 P53 Homo sapiens 64-67 9610789-0 1998 p53 mutations in cyclophosphamide-associated bladder cancer. Cyclophosphamide 17-33 P53 Homo sapiens 0-3 9610789-3 1998 We examined 19 cyclophosphamide-related bladder tumors to test the hypothesis that they might contain somatic mutations in the p53 tumor suppressor gene that could link a specific metabolite to the etiology of these cancers. Cyclophosphamide 15-31 P53 Homo sapiens 127-130 9610789-5 1998 The p53 mutation spectrum of these cyclophosphamide-associated bladder cancers differed significantly from patterns reported for sporadic (P = 0.020), smoking-related (0.043), and schistosomiasis-linked (P = 0.002) tumors but not arylamine-associated neoplasms (P = 0.860). Cyclophosphamide 35-51 P53 Homo sapiens 4-7 9635858-8 1998 Through a rigorous statistical test, the UV-induced p53 mutation spectrum appears to differ significantly (P < 0.008) from the one induced by the antineoplastic drug chloroethyl-cyclohexyl-nitrosourea, and to be indistinguishable from the one observed in NMSC (P = 0.4). Lomustine 169-203 P53 Homo sapiens 52-55 9548807-13 1998 Moreover, the induction of p53 by AZQ requires both the quinone and the aziridine moieties of the AZQ molecule. aziridine 72-81 P53 Homo sapiens 27-30 9482505-0 1998 Molecular epidemiology of p53 protein mutations in workers exposed to vinyl chloride. Vinyl Chloride 70-84 P53 Homo sapiens 26-29 9482505-3 1998 Workers exposed to vinyl chloride who are at risk for the development of the sentinel neoplasm angiosarcoma of the liver represent a model population for the study of such a mutant p53 biomarker, since vinyl chloride is known to cause specific p53 mutations in persons with angiosarcoma of the liver. Vinyl Chloride 19-33 P53 Homo sapiens 181-184 9482505-3 1998 Workers exposed to vinyl chloride who are at risk for the development of the sentinel neoplasm angiosarcoma of the liver represent a model population for the study of such a mutant p53 biomarker, since vinyl chloride is known to cause specific p53 mutations in persons with angiosarcoma of the liver. Vinyl Chloride 19-33 P53 Homo sapiens 244-247 9482505-3 1998 Workers exposed to vinyl chloride who are at risk for the development of the sentinel neoplasm angiosarcoma of the liver represent a model population for the study of such a mutant p53 biomarker, since vinyl chloride is known to cause specific p53 mutations in persons with angiosarcoma of the liver. Vinyl Chloride 202-216 P53 Homo sapiens 181-184 9482505-3 1998 Workers exposed to vinyl chloride who are at risk for the development of the sentinel neoplasm angiosarcoma of the liver represent a model population for the study of such a mutant p53 biomarker, since vinyl chloride is known to cause specific p53 mutations in persons with angiosarcoma of the liver. Vinyl Chloride 202-216 P53 Homo sapiens 244-247 9482505-4 1998 To determine the relation between vinyl chloride exposure and this p53 biomarker, the authors examined serum samples collected between 1987 and 1992 from a cohort of 225 French vinyl chloride workers and 111 unexposed controls (matched according to age, sex, race, smoking, and alcohol drinking) for the presence of mutant p53 protein, using an enzyme-linked immunosorbent assay. Vinyl Chloride 34-48 P53 Homo sapiens 67-70 9482505-5 1998 Stratification of the exposed workers by quartile of vinyl chloride exposure (in estimated ppm-years) yielded a statistically significant trend of increasing odds ratios for p53 biomarker seropositivity with increasing exposure. Vinyl Chloride 53-67 P53 Homo sapiens 174-177 9482505-6 1998 These results suggest that this serum biomarker for mutant p53 protein is related to vinyl chloride exposure and may be an early indicator of carcinogenic risk in exposed individuals. Vinyl Chloride 85-99 P53 Homo sapiens 59-62 10223623-0 1998 Infrequent p53 mutations in arsenic-related skin lesions. Arsenic 28-35 P53 Homo sapiens 11-14 10223623-6 1998 Accumulation of the p53 protein was detected (with a monoclonal DO-7 antibody) in 78% of the lesions from cases with arsenic exposure. Arsenic 117-124 P53 Homo sapiens 20-23 10223623-7 1998 Two of the six (30%) arsenic-related premalignant lesions and in addition one UV related carcinoma in situ lesion were clearly and repeatedly positive when p53 exons 5 to 8 were screened by a nonradioactive single-strand conformation polymorphism (SSCP) analysis. Arsenic 21-28 P53 Homo sapiens 156-159 10223623-10 1998 Our results suggest that the frequent accumulation of p53 protein in arsenic-related skin lesions is not due to p53 mutations. Arsenic 69-76 P53 Homo sapiens 54-57 9398049-0 1997 Modulation of p53 expression in cultured colonic adenoma cell lines by the naturally occurring lumenal factors butyrate and deoxycholate. Butyrates 111-119 P53 Homo sapiens 14-17 9398049-5 1997 We report that both butyrate and deoxycholate can down-regulate the expression of wild-type and mutant p53. Butyrates 20-28 P53 Homo sapiens 103-106 9315628-7 1997 Using different chelators to interfere with copper transport by PDTC, we found that bathocuproinedisulfonic acid (BCS), a non-cell-permeable chelator of Cu1+, prevented both copper import and p53 down-regulation. bathocuproine sulfonate 84-112 P53 Homo sapiens 192-195 9315628-7 1997 Using different chelators to interfere with copper transport by PDTC, we found that bathocuproinedisulfonic acid (BCS), a non-cell-permeable chelator of Cu1+, prevented both copper import and p53 down-regulation. bathocuproine sulfonate 114-117 P53 Homo sapiens 192-195 9315628-8 1997 In contrast, 1,10-orthophenanthroline, a cell-permeable chelator of Cu2+, promoted the redox activity of copper and up-regulated p53 DNA-binding activity through a DNA damage-dependent pathway. 1,10-orthophenanthroline 13-37 P53 Homo sapiens 129-132 9315663-7 1997 Notably, the lack of pRB in these U937-derived clones renders these p53-null cells highly resistant to apoptosis induced by serum withdrawal, calphostin C, and ceramide. Ceramides 160-168 P53 Homo sapiens 68-71 9374191-12 1997 In light of data suggesting that ALZ-50 recognizes a phosphorylated form of p53, we conclude that neuronal death in the developing nervous system involves the post-translational modification of an existing protein, p53. alz-50 33-39 P53 Homo sapiens 76-79 9374191-12 1997 In light of data suggesting that ALZ-50 recognizes a phosphorylated form of p53, we conclude that neuronal death in the developing nervous system involves the post-translational modification of an existing protein, p53. alz-50 33-39 P53 Homo sapiens 215-218 9266962-4 1997 Several observations indicate MG-132 alleviates squelching by influencing the conformation of newly synthesized p53 and E2F-1:MG-132 increased the fraction of wild type p53 bound by a monoclonal antibody which preferentially recognizes mutant conformers of p53, increased binding of hsp70 to p53 and inhibited nuclear accumulation of both p53 and E2F-1, but not the pocket protein p107. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 126-132 P53 Homo sapiens 112-115 9266962-4 1997 Several observations indicate MG-132 alleviates squelching by influencing the conformation of newly synthesized p53 and E2F-1:MG-132 increased the fraction of wild type p53 bound by a monoclonal antibody which preferentially recognizes mutant conformers of p53, increased binding of hsp70 to p53 and inhibited nuclear accumulation of both p53 and E2F-1, but not the pocket protein p107. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 126-132 P53 Homo sapiens 169-172 9266962-4 1997 Several observations indicate MG-132 alleviates squelching by influencing the conformation of newly synthesized p53 and E2F-1:MG-132 increased the fraction of wild type p53 bound by a monoclonal antibody which preferentially recognizes mutant conformers of p53, increased binding of hsp70 to p53 and inhibited nuclear accumulation of both p53 and E2F-1, but not the pocket protein p107. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 126-132 P53 Homo sapiens 169-172 9266962-4 1997 Several observations indicate MG-132 alleviates squelching by influencing the conformation of newly synthesized p53 and E2F-1:MG-132 increased the fraction of wild type p53 bound by a monoclonal antibody which preferentially recognizes mutant conformers of p53, increased binding of hsp70 to p53 and inhibited nuclear accumulation of both p53 and E2F-1, but not the pocket protein p107. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 126-132 P53 Homo sapiens 169-172 9266962-4 1997 Several observations indicate MG-132 alleviates squelching by influencing the conformation of newly synthesized p53 and E2F-1:MG-132 increased the fraction of wild type p53 bound by a monoclonal antibody which preferentially recognizes mutant conformers of p53, increased binding of hsp70 to p53 and inhibited nuclear accumulation of both p53 and E2F-1, but not the pocket protein p107. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 126-132 P53 Homo sapiens 169-172 9266962-6 1997 Because MG-132 and lactacycstin are highly specific inhibitors of the proteasome protease, our results suggest that the proteasome influences post-translational processes involved in proper folding and cytoplasmic clearing of E2F-1 and p53. benzyloxycarbonylleucyl-leucyl-leucine aldehyde 8-14 P53 Homo sapiens 236-239 9224745-9 1997 This study showed that significant overexpression of p53 protein was higher in BD with chronic arsenic exposure. Arsenic 95-102 P53 Homo sapiens 53-56 9136984-7 1997 In digitonin permeabilized cells IAF-p53 was imported into nuclei. Digitonin 3-12 P53 Homo sapiens 37-40 9069316-2 1997 METHODS AND MATERIALS: p53 status in primary and SV40 T antigen-transformed AT cell lines was analyzed using immunocytochemistry and by sequencing with the dideoxynucleotide termination method. Dideoxynucleotides 156-173 P53 Homo sapiens 23-26 9155049-6 1997 Interestingly, a strong statistical association was observed between p53 nuclear accumulation and MC (P = 0.0003). Methylcholanthrene 98-100 P53 Homo sapiens 69-72 9155049-8 1997 When we analysed the concomitant influence of MC and p53 expression on overall survival, we were able to confirm a real predominant role of MC in comparison with p53. Methylcholanthrene 140-142 P53 Homo sapiens 53-56 9155049-10 1997 These results underline the prognostic impact of MC and p53 protein accumulation in NSCLC and their reciprocal inter-relationship, supporting the hypothesis of a wild-type p53 regulation on the angiogenetic process through a VEGF up-regulation.

Carboplatin 161-172 P53 Homo sapiens 58-61 8900110-2 1996 The present studies demonstrate that the antimetabolite 1-beta-D-arabinofuranosylcytosine (ara-C) induces binding of c-Abl and p53. antimetabolite 1-beta-d-arabinofuranosylcytosine 41-89 P53 Homo sapiens 127-130 8651706-7 1996 The recombinant p53 isoforms were phosphorylated by 32P-labeling.

Sucrose 106-113 P53 Homo sapiens 87-90 8819013-2 1996 Vinyl chloride, a known human carcinogen that induces the rare sentinel neoplasm angiosarcoma of the liver, has been associated with specific A-->T transversions at the first base of codons 249 and 255 of the p53 gene. Vinyl Chloride 0-14 P53 Homo sapiens 212-215 8634092-0 1996 Preferential DNA damage in the p53 gene by benzo[a]pyrene metabolites in cytochrome P4501A1-expressing xeroderma pigmentosum group A cells. benzo 43-48 P53 Homo sapiens 31-34 8829621-4 1996 When cells were cultured in the presence of phosphotyrosine, there was a marked decrease in p53 expression. Phosphotyrosine 44-59 P53 Homo sapiens 92-95 8562931-4 1996 Whereas wild-type p53 activity per se induced maturation of certain cells, other underwent cell death judging from the reduced capability to exclude trypan blue and the appearance of fragmented DNA in flow cytometric analysis. Trypan Blue 149-160 P53 Homo sapiens 18-21 9081399-20 1996 Several genes are involved in control of this process; these include the p53 gene, mutations of which have been linked to cisplatin resistance in our laboratory studies, as well as in clinical trials with carboplatin. Carboplatin 205-216 P53 Homo sapiens 73-76 7658501-0 1995 Anti-p53 antibodies in sera of workers occupationally exposed to vinyl chloride. Vinyl Chloride 65-79 P53 Homo sapiens 5-8 7658501-3 1995 PURPOSE: The objective of this study was to determine the prevalence and time of appearance of serum anti-p53 antibodies during the pathogenesis of ASL associated with occupational exposure to vinyl chloride. Vinyl Chloride 193-207 P53 Homo sapiens 106-109 7658501-4 1995 METHODS: Enzyme-linked immunoassay (EIA) was used to detect anti-p53 antibodies in 148 serum samples from 92 individuals occupationally exposed (in France or in Kentucky) to vinyl chloride; 15 of these individuals (six from France and nine from Kentucky) had ASL. Vinyl Chloride 174-188 P53 Homo sapiens 65-68 7658501-12 1995 Four of the 77 vinyl chloride-exposed workers without diagnosed ASL were positive for anti-p53 antibodies; two of the four had symptoms related to vinyl chloride toxicity. Vinyl Chloride 15-29 P53 Homo sapiens 91-94 7658501-13 1995 Tumors from three of the six vinyl chloride-exposed workers from which sufficient DNA for analysis was obtained had A:T to T:A missense mutations of the p53 gene.
