WebH2AX phosphorylation can be induced by various exogenous agents such as ionizing radiation (IR) [6], DNA topoisomerase II inhibitors [7], etc. Recently, it was shown that one of the factors that cause the forma tion of γH2AX foci is hyperthermia [8]. Note that the induction of H2AX phosphorylation under heat

WebOne of the first events after induction of DSBs by IR is the phosphorylation of histone H2A.X, also referred to as γH2A.X, and the accumulation of the DDR protein 53BP1 which forms so-called IR induced foci (IRIF) at the site of the break ( Panier and Boulton, 2014 ). Web(IR)-induced foci (IRIF).12 ATM and ATR phosphorylate many of the same substrates, thereby initiating overlapping damage responses although recent evidence suggests that there is specificity as well as overlap in substrate phosphorylation. Of significance, ATM appears to preferentially target the transducer kinase, Chk2, whereas ATR

WebIR-induced clustered damage comprises two or more lesions (i.e., double-strand breaks (DSBs) as well as single-strand breaks or base damage on both strands) within less than 20 bp of DNA . In addition, the repair of these types of damage may cause new DSBs or other forms of misrepair, resulting in increased genomic instability [ 4 ].
