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 …
WebAug 13, 2004 · In this study, we show that Mcph1 forms IR-induced foci. Inhibition of Mcph1 expression by siRNA leads to the defective IR-induced intra-S-phase and G 2 /M checkpoints and is associated with decrease of Brca1 and Chk1 both at the mRNA and protein levels. 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
WebIrradiation is known to induce DSBs and trigger DNA damage repair response in diverse mammalian organs. 30 As a common RT-related toxicity, many studies have described IR-induced DSBs’ repairing kinetics in different kinds of cells. 31–33 Here, we proved that the γ-H2AX foci induced by single or repeated IR exposure followed a similar ...
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].
