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. WebAug 1, 2010 · For both foci types, the numbers of IRIF per nucleus were consistently highest at 2 h after therapy administration, whereas focus counts per nucleus decreased in parallel with the dose rate.

WebAug 1, 2009 · We, therefore, expected that the same tumors which showed RAD51 IRIF would also show IR-inducible BRCA1 foci formation. In the three tumors with intact RAD51 foci response, BRCA1 foci were largely absent in nonirradiated samples (0-3.7%; Fig. 3A) but could be detected in the treated samples at frequencies of 6% to 14% . The relative … 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.
