WebDec 30, 2015 · DNA damage repair elements accumulate at DNA damage sites to form ionizing radiation-induced foci (IRIF) for damage repair. IRIF, which represent direct evidence of DNA damage response activity, which are conveniently to be observed via immunofluorescence staining. WebIn both normal and cancer cells, DSBs promote the assembly of IR-induced foci (IRIF), domains of modified chromatin that serve a key role in DNA damage signaling. IRIF persistence is a critical determinant of accelerated senescence, making drugs that promote persistent IRIF an attractive strategy to sensitize cancer to genotoxic therapy. harrison chase general hospital
