Aphidicolin 143-154 checkpoint kinase 1 Homo sapiens 113-117 27634334-6 2016 Chemical and cytotoxic induction of replication stress, through aphidicolin, gemcitabine, camptothecin or hydroxyurea exposure, activates transcription of APOBEC3B via an ATR/Chk1-dependent pathway in vitro. Aphidicolin 64-75 checkpoint kinase 1 Homo sapiens 175-179 30657978-5 2019 We demonstrate that loss of WRN leads to enhanced ATM phosphorylation upon prolonged exposure to aphidicolin, a specific inhibitor of DNA polymerases, resulting in CHK1 activation. Aphidicolin 97-108 checkpoint kinase 1 Homo sapiens 164-168 17912033-8 2007 In aphidicolin-treated cells, there were lower levels of Serine 317-phosphorylated Chk1 when Plk2 was knocked-down. Aphidicolin 3-14 checkpoint kinase 1 Homo sapiens 83-87 21907702-5 2011 The mutation strongly attenuates aphidicolin induced Chk1 activation without altering the S-phase dependent Chk1 activation. Aphidicolin 33-44 checkpoint kinase 1 Homo sapiens 53-57 21212274-10 2011 In support of this hypothesis, DNA replication inhibitors such as hydroxyurea and aphidicolin similarly enhanced TAp73alpha expression and Chk1 phosphorylation. Aphidicolin 82-93 checkpoint kinase 1 Homo sapiens 139-143 16732333-5 2006 We demonstrate that both CHK1 and CHK2 are activated following treatment of cells with low doses of aphidicolin that induce fragile site breakage. Aphidicolin 100-111 checkpoint kinase 1 Homo sapiens 25-29 16828751-4 2006 In response to hydroxyurea, UV or aphidicolin, Claspin is phosphorylated in the Chk1-binding domain and its protein levels are increased in an ATR-dependent manner. Aphidicolin 34-45 checkpoint kinase 1 Homo sapiens 80-84 15538388-3 2004 In HeLa cells, depletion of either hRad17 or hMCM7 with small-interfering RNA suppressed ultraviolet (UV) light- or aphidicolin-induced hChk1 phosphorylation, and abolished UV-induced S-phase checkpoint activation. Aphidicolin 116-127 checkpoint kinase 1 Homo sapiens 136-141 14643438-3 2003 Treatment by aphidicolin and HU resulted in phosphorylation of Chk1, while HU, but not aphidicolin, induced focalization of gamma-H2AX and RPA. Aphidicolin 13-24 checkpoint kinase 1 Homo sapiens 63-67
