Irif foci
WebSep 14, 2012 · The accumulation of all these proteins at the damaged DNA site leads to the formation of ionizing radiation-induced foci (IRIF). IRIF maintenance until repair is critical for the maintenance of genomic stability, because, as it has been explained, they control various DNA and chromatin transactions and stimulate DNA repair. 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. Slightly but statistically significantly elevated γ-H2AX and 53BP1 levels were still present at 120–144 h after therapy ( Table 2; Fig. 3 ). Download figure

IRIF are thought to correspond to the sites of DNA double-strand breaks ( Du et al., 2003; Melo et al., 2001; Mirzoeva and Petrini, 2001; Rogakou et al., 1999 ).
WebNov 7, 2024 · Rap80/Abraxas/BRCA1 recruitment is diminished in Cezanne-deficient cells. We found that in cells depleted of Cezanne by siRNAs, IR-induced foci (IRIF) of Rap80 were significantly decreased (Fig. 2A,B).The Rap80 protein level, however, did not change in the knockdown cells (Fig. 2C), indicating that the diminished Rap80 IRIF was not due to … Webdamage foci, such as (ionizing) radiation-induced foci (IRIF or RIF) or DNA repair foci. In general they all refer to local accumulations or modifications of DNA damage response proteins that form at the sites of DNA double-strand breaks and can be visualized through microscopic imaging following immunocyto- or -histo-
WebFeb 21, 2024 · Of interest, upon DSB induction following exposure to radiation, many DDR factors tend to accumulate temporarily at sites of DNA damage, forming the so-called Ionizing Radiation-Induced Foci (IRIF) ( Ciccia and Elledge, 2010; Polo and Jackson, 2011 ). WebJul 1, 2005 · IRIF formation of Rad51 was investigated in Chinese hamster cells (V79 or CHO9), HeLa cells and primary human fibroblasts. In all cell types Rad51 foci could be detected, using the fixation and permeabilization technique described in Section 2.To determine the kinetics of Rad51 IRIF formation and the duration of detectable foci after …
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.
