Doxorubicin 160-170 mitogen-activated protein kinase 1 Homo sapiens 285-288 22787275-5 2012 We also demonstrate that activation of the extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase signaling pathway is involved in collagen-induced reduction of intracellular doxorubicin accumulation, collagen-induced up-regulation of ABCC1 expression levels, and collagen-mediated cell survival. Doxorubicin 197-208 mitogen-activated protein kinase 1 Homo sapiens 82-85 22469513-0 2012 Mitochondrial superoxide mediates doxorubicin-induced keratinocyte apoptosis through oxidative modification of ERK and Bcl-2 ubiquitination. Doxorubicin 34-45 mitogen-activated protein kinase 1 Homo sapiens 111-114 22457358-7 2012 Furthermore, activation of MAPK/ERK, but not PI3K/AKT, is required for ColI-mediated inhibition of doxorubicin-induced JNK activation and apoptosis and for ColI-mediated maintenance of Mcl-1 levels.

Doxorubicin 54-65 mitogen-activated protein kinase 1 Homo sapiens 90-127 22457358-0 2012 alpha2beta1 integrin promotes chemoresistance against doxorubicin in cancer cells through extracellular signal-regulated kinase (ERK). Doxorubicin 54-65 mitogen-activated protein kinase 1 Homo sapiens 129-132 19417026-1 2009 PURPOSE: Mitogen-activated protein kinase (MAPK) phosphatase-1 (MKP-1) dephosphorylates mitogen-activated protein kinase [extracellular signal-regulated kinase (ERK), c-Jun NH(2)-terminal kinase (JNK), and p38], mediates breast cancer chemoresistance, and is repressible by doxorubicin in breast cancer cells. Doxorubicin 274-285 mitogen-activated protein kinase 1 Homo sapiens 122-159 21854868-3 2011 Doxorubicin-induced caspase-8 activation was found to be mediated through Akt/ERK inactivation and FasL-independent Fas pathway in MCF-7 cells, while caspase-8 activation in MCF-7/Dox cells depended exclusively on FasL-stimulated Fas pathway. Doxorubicin 0-11 mitogen-activated protein kinase 1 Homo sapiens 78-81 21854868-3 2011 Doxorubicin-induced caspase-8 activation was found to be mediated through Akt/ERK inactivation and FasL-independent Fas pathway in MCF-7 cells, while caspase-8 activation in MCF-7/Dox cells depended exclusively on FasL-stimulated Fas pathway. Doxorubicin 0-3 mitogen-activated protein kinase 1 Homo sapiens 78-81 21854868-10 2011 Taken together, our data indicate that Akt/ERK-mediated caspase-8 activation and Fas/FasL-mediated caspase-8 activation mostly elucidate doxorubicin-induced death in MCF-7 cells and MCF-7/Dox cells, respectively. Doxorubicin 137-148 mitogen-activated protein kinase 1 Homo sapiens 43-46 21790999-3 2011 Because DOX causes cell death through upregulation of the MEK/ERK pathway, and sorafenib has an opposite influence on the same cascade, we hypothesized that co-treatment with these drugs may lead to an antagonistic effect. Doxorubicin 8-11 mitogen-activated protein kinase 1 Homo sapiens 62-65 21790999-9 2011 Similarly, ERK targeting with the selective inhibitor U0126 impaired DOX-induced toxicity. Doxorubicin 69-72 mitogen-activated protein kinase 1 Homo sapiens 11-14 21790999-12 2011 In conclusion, MEK/ERK counteraction, stimulation of survival via Akt and dysregulation of cyclin D1 could contribute to the escape from DOX-induced autophagy and thus promote cancer cell survival. Doxorubicin 137-140 mitogen-activated protein kinase 1 Homo sapiens 19-22 21472291-6 2010 Akt and ERK activation was also detected, and the inhibition of these two pathways resulted in the enhancement of ADM-induced apoptosis.

Doxorubicin 81-84 mitogen-activated protein kinase 1 Homo sapiens 38-41 23493035-10 2012 In contrast in MCF-7 cells the expression of ERK1/2 and phospho-ERK was increased after DOX treatment. Doxorubicin 88-91 mitogen-activated protein kinase 1 Homo sapiens 45-48 23028726-5 2012 Doxorubicin treatment showed the following dose-dependent effects: increase in the secretion of tumor necrosis factor alpha; decrease in the expression of phosphorylated protein kinase A and Bcl-2; and increase in the expression of phosphorylated signal transducer and activator of transcription 3, phosphorylated extracellular signal-regulated kinase (ERK), and ATF3. Doxorubicin 0-11 mitogen-activated protein kinase 1 Homo sapiens 314-351 23028726-5 2012 Doxorubicin treatment showed the following dose-dependent effects: increase in the secretion of tumor necrosis factor alpha; decrease in the expression of phosphorylated protein kinase A and Bcl-2; and increase in the expression of phosphorylated signal transducer and activator of transcription 3, phosphorylated extracellular signal-regulated kinase (ERK), and ATF3. Doxorubicin 0-11 mitogen-activated protein kinase 1 Homo sapiens 353-356 23028726-6 2012 Based on these results, we suggest that doxorubicin induces cytotoxicity through an ERK-dependent pathway, and ATF3 plays a pivotal role as a transcriptional regulator in this process. Doxorubicin 40-51 mitogen-activated protein kinase 1 Homo sapiens 84-87 21869603-5 2011 We have determined that chemotherapeutic drugs such as doxorubicin or the hormone based drug tamoxifen, both used to treat breast cancer, resulted in the activation of the Raf/MEK/ERK pathway which is often associated with a pro-proliferative, anti-apoptotic response. Doxorubicin 55-66 mitogen-activated protein kinase 1 Homo sapiens 180-183 21869603-6 2011 In drug sensitive MCF-7 cells which have wild-type p53; ERK, p53 and downstream p21 (Cip-1 ) were induced upon exposure to doxorubicin. Doxorubicin 123-134 mitogen-activated protein kinase 1 Homo sapiens 56-59 21881167-8 2011 However, constitutive Akt-1 activation in drug-resistant cells containing high levels of active ERK completely escaped cellular senescence induced by doxorubicin and tamoxifen. Doxorubicin 150-161 mitogen-activated protein kinase 1 Homo sapiens 96-99 21300134-14 2011 CONCLUSION: Doxorubicin can increase expression of mdr1/P-glycoprotein through activating MAPK/ERK transduction pathway, then increasing expression of YB-1, inducing YB-1 nuclear translocation, and enhancing DNA-binding activity of YB-1.

Doxorubicin 21-32 mitogen-activated protein kinase 1 Homo sapiens 111-114 18974122-8 2008 The phosphorylation of Akt and extracellular signal-regulated kinase 1/2 (ERK1/2) is elevated in Cas-overexpressing cells treated with Adriamycin, whereas expression of the proapoptotic protein Bak is decreased. Doxorubicin 135-145 mitogen-activated protein kinase 1 Homo sapiens 31-72 19223549-7 2009 This XIAP-dependent event occurs in response to camptotechin or etoposide/VP16; however, XIAP is dispensable for activation of NF-kappaB by doxorubicin, which engages a MEK-ERK pathway to activate IKK. Doxorubicin 140-151 mitogen-activated protein kinase 1 Homo sapiens 173-176 18468633-0 2008 The effect of doxorubicin on MEK-ERK signaling predicts its efficacy in HCC. Doxorubicin 14-25 mitogen-activated protein kinase 1 Homo sapiens 33-36 18468633-7 2008 At early time points (30 min) after DOX treatment of Hep3B cells, MEK activity was unchanged at low doses and decreased at higher doses; after 24 h, phospho-ERK levels increased at higher doses. Doxorubicin 36-39 mitogen-activated protein kinase 1 Homo sapiens 157-160 18468633-8 2008 Contrarily, in HepG2 cells, DOX caused a sustained, dose-dependent increase in phospho-ERK levels at early and late time points. Doxorubicin 28-31 mitogen-activated protein kinase 1 Homo sapiens 87-90 16428504-11 2006 Furthermore, 17-AAG depleted cellular contents of Akt, decreased extracellular signal-regulated kinase (ERK) phosphorylation, and reduced cellular FLICE-like inhibitory protein levels (FLIP), and thus enhanced the cytotoxic effect of doxorubicin and agonistic anti-tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) death receptor antibodies. Doxorubicin 234-245 mitogen-activated protein kinase 1 Homo sapiens 65-102 17658517-3 2007 Under senescence-inducing condition, decreased Erk phosphorylation was detected in caRhoA-transfected cells and inactivation of Erk, but not p38, prevented doxorubicin-induced cell senescence. Doxorubicin 156-167 mitogen-activated protein kinase 1 Homo sapiens 128-131 16269455-8 2006 The results showed that OEA, through activation of Ras-Raf-1-Mek-Erk signaling, inhibited doxorubicin-induced apoptosis. Doxorubicin 90-101 mitogen-activated protein kinase 1 Homo sapiens 65-68 18256541-7 2008 Prolonged treatment with two commonly-used chemotoxic compounds, doxorubicin and paclitaxel, caused increased activation of ERK in PTEN-positive DU145 cells, but not PTEN-negative PC3 cells. Doxorubicin 65-76 mitogen-activated protein kinase 1 Homo sapiens 124-127 17384286-0 2006 Superoxide anions are involved in doxorubicin-induced ERK activation in hepatocyte cultures. Doxorubicin 34-45 mitogen-activated protein kinase 1 Homo sapiens 54-57 17384286-7 2006 In this work, we have determined the possible involvement of particular free radicals in DOX-induced ERK phosphorylation in hepatocyte cultures by using specific free radical scavengers. Doxorubicin 89-92 mitogen-activated protein kinase 1 Homo sapiens 101-104 15494689-1 2004 AIM: To understand the biochemical basis of cell sensitivity to cytotoxic effect of doxorubicine (DOX), we investigated signaling cascades mediated by c-Jun N-terminal protein kinases (JNK1/2), p38 mitogen-activated protein kinases (MAPK), extracellular signal-regulated protein kinase (ERK1/2) and protein kinase B/Akt in both DOX-sensitive BL41 and the DOX-resistant DG75 Burkitt"s lymphoma (BL) cell lines. Doxorubicin 84-96 mitogen-activated protein kinase 1 Homo sapiens 194-197 15870880-5 2005 To confirm these findings, the MAPK signal transduction cascade was activated with EGF and response to doxorubicin or paclitaxel was measured in the presence/absence of the MEK-specific inhibitor, U0126. Doxorubicin 103-114 mitogen-activated protein kinase 1 Homo sapiens 31-35 15494689-6 2004 RESULTS: Our findings demonstrated that DOX treatment of the BL41 cells led to sustained activation of JNK1/2 and p38 MAPK. Doxorubicin 40-43 mitogen-activated protein kinase 1 Homo sapiens 114-117 15494689-7 2004 This activation/phosphorylation did not result from increased expression of either JNK1/2 or p38 MAPK since protein levels of JNK1/2 and p38 MAPK in DOX-treated and untreated cells were unaltered. Doxorubicin 149-152 mitogen-activated protein kinase 1 Homo sapiens 137-140 15494689-9 2004 The effect of DOX in drug-resistant cell line DG75 convoyed by dephosphorylation of JNK1/2, p38 MAPK and activation of Akt. Doxorubicin 14-17 mitogen-activated protein kinase 1 Homo sapiens 92-95 16059641-5 2005 Furthermore, treatments of both cell lines by QU and in its combined application with DOX increased phosphorylation of ERK, while Akt-1 and phosphorylated Akt-1 levels were not changed. Doxorubicin 86-89 mitogen-activated protein kinase 1 Homo sapiens 119-122 15116093-3 2004 In breast carcinoma MCF7 cells, doxorubicin (300 nM) activated ERK2 and induced phosphorylation of p53 on Thr55 residues. Doxorubicin 32-43 mitogen-activated protein kinase 1 Homo sapiens 63-67 15494689-11 2004 CONCLUSION: The outcome of cellular response to DOX in BL cell lines is determined by interference of at least three signaling pathways: JNK1/2, p38 MAPK and PKB/Akt. Doxorubicin 48-51 mitogen-activated protein kinase 1 Homo sapiens 145-148 15116093-0 2004 Phosphorylation of p53 on Thr55 by ERK2 is necessary for doxorubicin-induced p53 activation and cell death. Doxorubicin 57-68 mitogen-activated protein kinase 1 Homo sapiens 35-39 15116093-1 2004 We recently reported that exposure of human cervical carcinoma cells to doxorubicin results in extracellular signal-regulated kinase (ERK)2 activation, which in turn phosphorylates p53 on a previously uncharacterized site, Thr55. Doxorubicin 72-83 mitogen-activated protein kinase 1 Homo sapiens 95-139 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. Doxorubicin 86-97 mitogen-activated protein kinase 1 Homo sapiens 35-39 15116093-9 2004 In summary, our results suggest that phosphorylation of p53Thr55 by ERK2 is important for doxorubicin-induced p53 activation and cell death. Doxorubicin 90-101 mitogen-activated protein kinase 1 Homo sapiens 68-72 12883037-5 2003 We identified that serum starvation and Dox reduced phosphorylation of mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase (MEK), protein kinase C (PKC) alpha/beta and c-Jun NH(2)-terminal kinase. Doxorubicin 40-43 mitogen-activated protein kinase 1 Homo sapiens 143-146 12907245-0 2003 The JNK, ERK and p53 pathways play distinct roles in apoptosis mediated by the antitumor agents vinblastine, doxorubicin, and etoposide. Doxorubicin 109-120 mitogen-activated protein kinase 1 Homo sapiens 9-12 12907245-8 2003 Inhibition of ERK signaling by the MEK inhibitor, U0126, potentiated the cytotoxic effects of vinblastine and doxorubicin, but not that of VP-16. Doxorubicin 110-121 mitogen-activated protein kinase 1 Homo sapiens 14-17 14755690-7 2004 Inhibition of PI 3K/Akt and p38 accelerated and enhanced doxorubicin-induced cell death. Doxorubicin 57-68 mitogen-activated protein kinase 1 Homo sapiens 28-31 14755690-10 2004 Activation of PI 3K/Akt and p38 modulates apoptotic signal pathways and inhibits doxorubicin-induced cell death. Doxorubicin 81-92 mitogen-activated protein kinase 1 Homo sapiens 28-31 12883037-7 2003 Thus, our data suggest that apoptosis and down-regulation of XIAP induced by Dox exposure or serum starvation may be mediated through inactivation of the MEK/ERK and PKCalpha/beta pathways. Doxorubicin 77-80 mitogen-activated protein kinase 1 Homo sapiens 158-161 34783124-7 2022 Furthermore, the polymerase chain reaction array results illustrate activation of mitogen-activated protein kinase (MAPK) gene expression (AKT, ERK, and MAPK) during doxorubicin alone treatment and it has been attenuated by ginsenoside Rg1 pretreatment. Doxorubicin 166-177 mitogen-activated protein kinase 1 Homo sapiens 144-147 12394272-7 2002 Interestingly, treatment with EBPC in combination with the chemotherapeutic drugs increased ERK activity as compared to treatment with the chemotherapeutic drugs, suggesting a possible role for the ERK pathway in mediating doxorubicin- or cisplatin-induced cell death. Doxorubicin 223-234 mitogen-activated protein kinase 1 Homo sapiens 92-95 12394272-7 2002 Interestingly, treatment with EBPC in combination with the chemotherapeutic drugs increased ERK activity as compared to treatment with the chemotherapeutic drugs, suggesting a possible role for the ERK pathway in mediating doxorubicin- or cisplatin-induced cell death. Doxorubicin 223-234 mitogen-activated protein kinase 1 Homo sapiens 198-201 11996883-1 2002 In this study, we showed that suppression of the MEK-ERK transduction pathway by a selective inhibitor, 2"-amino-3"-methoxyflavone (PD98059), increased drug resistance of SiHa cells to cisplatin, but not to another common anticancer drug, doxorubicin. Doxorubicin 239-250 mitogen-activated protein kinase 1 Homo sapiens 53-56 11996883-3 2002 Both cisplatin and doxorubicin activated nuclear ERK2 and nuclear transcription factor kappa B (NF kappa B) of SiHa cells. Doxorubicin 19-30 mitogen-activated protein kinase 1 Homo sapiens 49-53 11409876-0 2001 Nuclear extracellular signal-regulated kinase 2 phosphorylates p53 at Thr55 in response to doxorubicin. Doxorubicin 91-102 mitogen-activated protein kinase 1 Homo sapiens 8-47 11409876-1 2001 In this study, we showed that nuclear ERK2 phosphorylates p53 at Thr55 in response to doxorubicin. Doxorubicin 86-97 mitogen-activated protein kinase 1 Homo sapiens 38-42 11170175-7 2001 Doxorubicin (0.2 microM), an anticancer drug whose mechanism of action is independent of microtubules, also induced ERK activation, tau phosphorylation and apoptosis. Doxorubicin 0-11 mitogen-activated protein kinase 1 Homo sapiens 116-119 8913269-1 1996 We studied the activation of c-jun N-terminal kinase 1 (JNK 1) and extracellular signal-regulated kinases 1 and 2 (ERK 1/2) of mitogen-activated protein kinase (MAPK) family by adriamycin (ADR) in the human T cell leukemia line, H9. Doxorubicin 177-187 mitogen-activated protein kinase 1 Homo sapiens 67-113 33771646-5 2021 While doxorubicin was identified to activate the pathways TGF-beta and ERK/MAPK, lercanidipinewas found to inhibit these pathways. Doxorubicin 6-17 mitogen-activated protein kinase 1 Homo sapiens 71-74 33771646-7 2021 In multiple cellular models from different lineages, the cells with less sensitivity to doxorubicin were found to have the inherent activation of ERK/MAPK and TGF-beta pathways. Doxorubicin 88-99 mitogen-activated protein kinase 1 Homo sapiens 146-149 35039569-10 2022 In cell lines, mutant RASGRP4 increased basal p-ERK expression and lead to a growth advantage in colony forming assays when challenged with doxorubicin.

Doxorubicin 73-76 mitogen-activated protein kinase 1 Homo sapiens 194-197 34589399-14 2021 What" more, for the first time, we also found miR34a combined with Dox could obviously inhibit the expression of Snail through suppressing Notch/NF-kappaB and RAS/RAF/MEK/ERK pathway in MCF-7/A cells. Doxorubicin 67-70 mitogen-activated protein kinase 1 Homo sapiens 171-174 34119884-3 2021 Herein, we developed a nanovector Exo-PMA/Fe-HSA@DOX through cloaked by urinary exosome membrane as a chemo/chemodynamic theranostic nano-platform for targeted homologous prostate cancer therapy which pertain to the abrogation of Epidermal Growth Factor Receptor (EGFR) and its downstream AKT/NF-kB/IkB signaling instead of ERK signaling cascades. Doxorubicin 49-52 mitogen-activated protein kinase 1 Homo sapiens 324-327 35395977-9 2022 CONCLUSION: DOX can induce apoptosis of H929 via intrinsic apoptosis pathway, and MEK/ERK pathway and c-Jun possibly play a role in this process. Doxorubicin 12-15 mitogen-activated protein kinase 1 Homo sapiens 86-89 35209071-5 2022 Therefore, we investigated the effects of UA on invasion and metastasis, ODC-related polyamine metabolism, and MAPK-Erk-VEGF/MMP-9 signaling pathways in a doxorubicin-resistant breast cancer cell (MCF-7/ADR) model.
