Ir-induced foci
WebApr 4, 2003 · The IR-induced foci are drawn on top of the background value obtained in a parallel sample (filled columns). ( B ) Distribution of MRC-5 cells with n foci for an unirradiated sample (filled columns) and for cells irradiated with 1.2 mGy and incubated for various repair times (hatched and open columns). WebJun 13, 2005 · The individual in vivo kinetics for foci loss at 1,000 mGy·cm were averaged and compared with kinetics obtained after a 20-mGy in vitro exposure of fibroblasts . The comparison with fibroblasts was performed because previous studies had shown that in this cell type the loss of IR-induced foci correlates with DSB repair (17, 20–22).

WebTo test this hypothesis, we monitored IR-induced nuclear foci formation for RNF8, 53BP1, BRCA1, γ-H2AX, and RNF168 in the presence or absence of KPNA2. Results indicated that depletion of KPNA2 resulted in fewer foci for four of these proteins, RNF8, 53BP1, BRCA1, and RNF168 ( Figure 4 C), similar to what had been previously observed for MDC1 ...
