WebJan 1, 2016 · The induction of apoptosis, assayed by PARP cleavage, did not occur until 8 hr post-Cr (VI) exposure, indicating that CHK2 phosphorylation and, by extension, ATM activation were not triggered by apoptotic DNA fragmentation. WebIn human cells, following genotoxic stress, CHK2 is activated and phosphorylates >20 proteins to induce the appropriate cellular response, which, depending on the extent of damage, the cell type, and other factors, could be cell cycle checkpoint activation, induction of apoptosis or senescence, DNA repair, or tolerance of the damage.
