WebIR is a prototypical DNA-damaging agent and IR-induced DNA double-strand breaks (DSBs) are recognized by the DNA damage response (DDR) network of cellular pathways that sense, signal, and repair DNA lesions. WebJul 30, 2024 · Using time-lapse imaging, we found that HT could delay and decrease the formation of 53BP1 IR-induced foci (IRIF). Moreover, through the in situ tracking of individual IRIF, it was observed that HT resulted in more unrepaired IRIF over the period of observation compared with treatment with IR alone. Additionally, the unrepaired IRIF had …
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 … WebBAP1 promotes the repair of UV-induced DNA damage via PARP1-mediated recruitment to damage sites and control of activity and stability.
