Serine 43-46 ataxia telangiectasia mutated Mus musculus 57-60 16251211-7 2005 The nuclear localization of ATBF1 was suppressed by treatment with caffeine, an inhibitor of PI(3)K-related kinase activity of ataxa-telangiectasia mutated (ATM) gene product. Caffeine 67-75 ataxia telangiectasia mutated Mus musculus 127-155 16251211-7 2005 The nuclear localization of ATBF1 was suppressed by treatment with caffeine, an inhibitor of PI(3)K-related kinase activity of ataxa-telangiectasia mutated (ATM) gene product. Caffeine 67-75 ataxia telangiectasia mutated Mus musculus 157-160 16138010-4 2005 However, wortmannin at a concentration, that inhibits ATM kinase but not ATR kinase, did not affect cell cycle progression. Wortmannin 9-19 ataxia telangiectasia mutated Mus musculus 54-57 16799786-3 2006 We have also shown that mice haploinsufficient for ATM develop cataracts earlier than wild-type animals, when exposed to either low-LET X-rays or high-LET (56)Fe ions. Iron 159-161 ataxia telangiectasia mutated Mus musculus 51-54 16400190-4 2006 To test this hypothesis, we treated a congenic strain of Atm+/- mice with DMBA (7,12-dimethylbenz(alpha)anthracene), a mammary carcinogen, and observed mammary tumor incidence. 6,11-dimethylbenzo(b)naphtho(2,3-d)thiophene 74-78 ataxia telangiectasia mutated Mus musculus 57-60 16141284-7 2005 P53 was transiently phosphorylated at serine 23 during liver regeneration in an Atm-dependent manner. Serine 38-44 ataxia telangiectasia mutated Mus musculus 80-83 15998665-5 2005 We found that DNA-PKcs can be ruled out as an essential kinase in this process, whereas ATM is strictly required for the chromatin-wide phosphorylation of H2AX occurring in leptotene spermatocytes in response to DSBs. dsbs 212-216 ataxia telangiectasia mutated Mus musculus 88-91 16189003-6 2005 The incubation of infected cells with caffeine, a known ATM inhibitor, did not block entry into S but reduced the rate of viral compared to cellular DNA synthesis. Caffeine 38-46 ataxia telangiectasia mutated Mus musculus 56-59 16081118-9 2005 Atm and p53 knockout mice deficient in DNA damage response/repair are more susceptible to xenobiotic or radiation embryopathies, suggesting a teratological role for DNA damage, consistent with enhanced susceptibility to methamphetamine in ogg1 knockout mice with deficient repair of oxidative DNA damage. Methamphetamine 220-235 ataxia telangiectasia mutated Mus musculus 0-3 15863839-4 2005 In contrast, the plasma cholesterol level was significantly higher in ATM(+)(/-)/ApoE(-)(/-) mice than in ATM(+)(/+)/ApoE(-)(/-) control mice. Cholesterol 24-35 ataxia telangiectasia mutated Mus musculus 70-73 15863839-4 2005 In contrast, the plasma cholesterol level was significantly higher in ATM(+)(/-)/ApoE(-)(/-) mice than in ATM(+)(/+)/ApoE(-)(/-) control mice. Cholesterol 24-35 ataxia telangiectasia mutated Mus musculus 106-109 15888486-1 2005 We previously demonstrated that the nitroxide antioxidant tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl) increased latency to tumorigenesis and doubled (100%) the lifespan of Atm-deficient mice, a mouse model of ataxia telangiectasia, which displays accelerated oxidative damage and stress. tempol 66-113 ataxia telangiectasia mutated Mus musculus 184-187 15735681-4 2005 The results indicate that ATM kinase is likely to be indispensable for the p53-dependent S-phase checkpoint since the suppression was abrogated by inhibitors such as caffeine and wortmannin. Caffeine 166-174 ataxia telangiectasia mutated Mus musculus 26-29 15888486-1 2005 We previously demonstrated that the nitroxide antioxidant tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl) increased latency to tumorigenesis and doubled (100%) the lifespan of Atm-deficient mice, a mouse model of ataxia telangiectasia, which displays accelerated oxidative damage and stress. Hydroxylamine 36-45 ataxia telangiectasia mutated Mus musculus 184-187 15888486-1 2005 We previously demonstrated that the nitroxide antioxidant tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl) increased latency to tumorigenesis and doubled (100%) the lifespan of Atm-deficient mice, a mouse model of ataxia telangiectasia, which displays accelerated oxidative damage and stress. tempol 58-64 ataxia telangiectasia mutated Mus musculus 184-187 15735681-4 2005 The results indicate that ATM kinase is likely to be indispensable for the p53-dependent S-phase checkpoint since the suppression was abrogated by inhibitors such as caffeine and wortmannin. Wortmannin 179-189 ataxia telangiectasia mutated Mus musculus 26-29 15864314-4 2005 Discovery of this intestinal radiosensitivity mechanism allowed design of an antisense Atm oligonucleotide treatment which phenocopied the Atm(-/-) mouse, reordering ceramide synthase-mediated stem cell death to become the first-line gastrointestinal response of wild-type littermates. Oligonucleotides 91-106 ataxia telangiectasia mutated Mus musculus 87-90 15864314-4 2005 Discovery of this intestinal radiosensitivity mechanism allowed design of an antisense Atm oligonucleotide treatment which phenocopied the Atm(-/-) mouse, reordering ceramide synthase-mediated stem cell death to become the first-line gastrointestinal response of wild-type littermates. Oligonucleotides 91-106 ataxia telangiectasia mutated Mus musculus 139-142 15570424-0 2005 Control of Atm-/- thymic lymphoma cell proliferation in vitro and in vivo by dexamethasone. Dexamethasone 77-90 ataxia telangiectasia mutated Mus musculus 11-14 15701627-7 2005 Caffeine, an inhibitor of the upstream checkpoint kinases ATM (ataxia telangiectasia-mutated) and ATR (ATM and Rad3-related), has no effect on the early inhibition of DNA synthesis, but cells are no longer able to maintain the block after 8 h. Instead, the addition of caffeine leads to arrest of cells in G(2)/M rather than S-phase after 24 h. Analysis of signaling pathways in cell extracts reveals an activation of Chk1 after treatment with MMS and 4-AN, which can be suppressed by caffeine. Caffeine 0-8 ataxia telangiectasia mutated Mus musculus 58-61 15570424-4 2005 The primary objectives of the present study were (1) to investigate possible mechanisms underlying the tumor-suppressing effect of Dex on Atm-/- thymic lymphoma cells, and (2) to determine whether Dex is an effective tumor-suppressing treatment in mice bearing transplanted Atm-/- thymic tumors. Dexamethasone 131-134 ataxia telangiectasia mutated Mus musculus 138-141 15570424-9 2005 In Atm+/+ mice transplanted subcutaneously with ATL-1 cells, tumor growth was either prevented completely or significantly suppressed by Dex treatment. Dexamethasone 137-140 ataxia telangiectasia mutated Mus musculus 3-6 15570424-10 2005 CONCLUSIONS: Our findings identify potential mechanisms by which Dex affects the proliferation and survival of ATL-1 cells in culture, and provide evidence that Dex can suppress the proliferation of Atm-/- thymic lymphoma cells growing in the body. Dexamethasone 161-164 ataxia telangiectasia mutated Mus musculus 199-202 15570424-7 2005 RESULTS: Atm-/- tumor cells were highly sensitive to Dex, both in culture and in vivo as ectopic tumors in mice. Dexamethasone 53-56 ataxia telangiectasia mutated Mus musculus 9-12 15735814-0 2005 The alkylating carcinogen N-methyl-N"-nitro-N-nitrosoguanidine activates the plasminogen activator inhibitor-1 gene through sequential phosphorylation of p53 by ATM and ATR kinases. Methylnitronitrosoguanidine 26-62 ataxia telangiectasia mutated Mus musculus 161-164 15735814-4 2005 Here, we show that ATM and ATR kinases, but not DNA-PK, which participate in DNA damage-activated checkpoints, regulate the phosphorylation of p53 at serine 15 in response to MNNG cell treatment. Serine 150-156 ataxia telangiectasia mutated Mus musculus 19-22 15922113-4 2005 Interestingly, flavonoids with chemopreventative effects, such as quercetin, genistein, and epigallocatechin gallate activate ATM. Flavonoids 15-25 ataxia telangiectasia mutated Mus musculus 126-129 15735814-5 2005 Using ATM-deficient cells, ATM was shown to be required for early phosphorylation of serine 15 in response to MNNG, whereas catalytically inactive ATR selectively interfered with late phase serine 15 phosphorylation. Serine 85-91 ataxia telangiectasia mutated Mus musculus 27-30 15546863-8 2005 Further supporting these results, we also observed that biological responses tightly regulated by Akt, such as transcription factor of the forkhead family activity after insulin treatment or gamma-radiation response, were altered in cell lines derived from AT patients and knockout mice for ATM in which phosphorylation in serine 473 was almost abolished. Serine 323-329 ataxia telangiectasia mutated Mus musculus 291-294 15922113-4 2005 Interestingly, flavonoids with chemopreventative effects, such as quercetin, genistein, and epigallocatechin gallate activate ATM. Quercetin 66-75 ataxia telangiectasia mutated Mus musculus 126-129 15922113-4 2005 Interestingly, flavonoids with chemopreventative effects, such as quercetin, genistein, and epigallocatechin gallate activate ATM. Genistein 77-86 ataxia telangiectasia mutated Mus musculus 126-129 15694690-5 2005 Recently, we found that the ATM gene product (mutated in ataxia-telangiectasia, A-T), is required for cell survival and genomic stability maintenance following exposure to low labile iron concentrations. Iron 183-187 ataxia telangiectasia mutated Mus musculus 28-31 15922113-4 2005 Interestingly, flavonoids with chemopreventative effects, such as quercetin, genistein, and epigallocatechin gallate activate ATM. epigallocatechin gallate 92-116 ataxia telangiectasia mutated Mus musculus 126-129 15694690-6 2005 Iron chelators (desferal, quercetin, and apoferritin) also increase A-T cell genomic stability and viability, and activate ATM-dependent cellular events in normal cells. Iron 0-4 ataxia telangiectasia mutated Mus musculus 123-126 15922113-5 2005 Since ATM activates pathways which increase genomic stability, oxidant resistance, and/or telomere stability, and since many diseases of old age (i.e., cancer, cardiovascular and neurodegenerative disease), result from attenuation of these pathways, pharmacologic manipulation of ATM activity via flavonoid intake may prove useful in slowing the appearance of age-associated disease. Flavonoids 297-306 ataxia telangiectasia mutated Mus musculus 6-9 15694690-6 2005 Iron chelators (desferal, quercetin, and apoferritin) also increase A-T cell genomic stability and viability, and activate ATM-dependent cellular events in normal cells. Deferoxamine 16-24 ataxia telangiectasia mutated Mus musculus 123-126 15213104-3 2004 We tested this hypothesis by determining whether the well-described nitroxide antioxidant, tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), acts as a chemopreventative agent in Atm mutant mice, a model of the human cancer prone syndrome ataxia-telangiectasia. Hydroxylamine 68-77 ataxia telangiectasia mutated Mus musculus 185-188 15694690-6 2005 Iron chelators (desferal, quercetin, and apoferritin) also increase A-T cell genomic stability and viability, and activate ATM-dependent cellular events in normal cells. Quercetin 26-35 ataxia telangiectasia mutated Mus musculus 123-126 15694690-8 2005 Based on this, we propose that iron chelators protect the substantia nigra pars compacta not only by chelating labile iron and reducing oxyradical formation, but also by inducing ATM activity, leading to increased oxidative stress resistance and DNA repair. Iron 31-35 ataxia telangiectasia mutated Mus musculus 179-182 15694690-9 2005 Support for this hypothesis comes from the recent observation that the iron chelating flavonoid quercetin both directly activates ATM and protects neuronal cells from the toxic effects of the N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine.

Quercetin 96-105 ataxia telangiectasia mutated Mus musculus 130-133 15694690-10 2005 Therefore since; (1) ATM is required for iron toxicity resistance, (2) iron chelators such as quercetin, desferal, and apoferritin induce ATM activity and/or ATM-dependent events, and (3), Atm-deficient mice preferentially lose dopaminergic nigro-striatal neurons, we propose that ATM activity has an important function in PD.

Deferoxamine 105-113 ataxia telangiectasia mutated Mus musculus 138-141 15694690-11 2005 Furthermore, pharmacological manipulation of ATM activity via iron chelation might have clinical efficacy in PD treatment. Iron 62-66 ataxia telangiectasia mutated Mus musculus 45-48 15496926-4 2004 Atm-/- mice older than 24 weeks showed progressive bone marrow failure resulting from a defect in HSC function that was associated with elevated reactive oxygen species. Reactive Oxygen Species 145-168 ataxia telangiectasia mutated Mus musculus 0-3 15336622-5 2004 We also show that labile iron levels are significantly elevated in Atm-deficient mouse sera compared to syngeniec wild type mice. Iron 25-29 ataxia telangiectasia mutated Mus musculus 67-70 15213104-3 2004 We tested this hypothesis by determining whether the well-described nitroxide antioxidant, tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), acts as a chemopreventative agent in Atm mutant mice, a model of the human cancer prone syndrome ataxia-telangiectasia. tempol 91-97 ataxia telangiectasia mutated Mus musculus 185-188 15213104-3 2004 We tested this hypothesis by determining whether the well-described nitroxide antioxidant, tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), acts as a chemopreventative agent in Atm mutant mice, a model of the human cancer prone syndrome ataxia-telangiectasia. tempol 99-145 ataxia telangiectasia mutated Mus musculus 185-188 15010311-0 2004 Loss of ATM sensitizes against O6-methylguanine triggered apoptosis, SCEs and chromosomal aberrations. O-(6)-methylguanine 31-47 ataxia telangiectasia mutated Mus musculus 8-11 15289318-4 2004 We examined the effect of dietary supplementation with the thiol-containing antioxidant N-acetyl-l-cysteine (NAC) on levels of oxidative DNA damage and the frequency of DNA deletions in Atm-deficient (AT-mutated) mice. Sulfhydryl Compounds 59-64 ataxia telangiectasia mutated Mus musculus 186-189 15289318-6 2004 Furthermore, we found that Atm-deficient mice have significantly increased levels of 8-OH deoxyguanosine, an indication of oxidative DNA damage. 8-oh deoxyguanosine 85-104 ataxia telangiectasia mutated Mus musculus 27-30 15289318-7 2004 Dietary supplementation with NAC significantly reduced 8-OH deoxyguanosine level and the frequency of DNA deletions in Atm-deficient mice. Acetylcysteine 29-32 ataxia telangiectasia mutated Mus musculus 119-122 15289318-9 2004 Our findings demonstrate that NAC counteracts genetic instability and suggest that genetic instability may be a consequence of oxidative stress in Atm-deficient mice. Acetylcysteine 30-33 ataxia telangiectasia mutated Mus musculus 147-150 15178448-3 2004 It was shown by biochemical fractionation procedure that PARP-1 as well as ATM increases at chromatin level after induction of DSB with neocarzinostatin (NCS).

Selenious Acid 15-23 ataxia telangiectasia mutated Mus musculus 222-225 12796033-6 2003 Loss of ATM function did not result in increased apoptosis, but resulted in increased Trypan Blue staining in response to epirubicin, suggesting that processes other than apoptosis may mediate cytotoxicity. Trypan Blue 86-97 ataxia telangiectasia mutated Mus musculus 8-11 12796033-6 2003 Loss of ATM function did not result in increased apoptosis, but resulted in increased Trypan Blue staining in response to epirubicin, suggesting that processes other than apoptosis may mediate cytotoxicity.
