Dexrazoxane 41-52 activating transcription factor 3 Homo sapiens 73-77 25521189-2 2015 EXPERIMENTAL APPROACH: We investigated the DNA damage response and the role of the activating transcription factor 3 (ATF3) accumulation in tumour cells exposed to dexrazoxane. Dexrazoxane 164-175 activating transcription factor 3 Homo sapiens 83-116 25521189-2 2015 EXPERIMENTAL APPROACH: We investigated the DNA damage response and the role of the activating transcription factor 3 (ATF3) accumulation in tumour cells exposed to dexrazoxane. Dexrazoxane 164-175 activating transcription factor 3 Homo sapiens 118-122 25521189-6 2015 ATF3 protein was induced by dexrazoxane in a concentration- and time-dependent manner, which was abolished in TOP2A-depleted cells and in cells pre-incubated with ATM inhibitor. Dexrazoxane 28-39 activating transcription factor 3 Homo sapiens 0-4 25521189-7 2015 Knockdown of ATF3 gene expression by siRNA triggered apoptosis in control cells and diminished the p53 protein level in both control and dexrazoxane -treated cells. Dexrazoxane 137-148 activating transcription factor 3 Homo sapiens 13-17 25521189-9 2015 ATF3 knockdown also delayed the repair of dexrazoxane -induced DNA double-strand breaks. Dexrazoxane 42-53 activating transcription factor 3 Homo sapiens 0-4 25521189-11 2015 The DNA damage-triggered ATF3 controlled p53 accumulation and generation of double-strand breaks and is proposed to serve as a switch between DNA damage and cell death following dexrazoxane treatment. Dexrazoxane 178-189 activating transcription factor 3 Homo sapiens 25-29
