The kinases of the PI3-family (Ataxia telangiectasia mutated, ATR and DNA-PKcs) are responsible for this phosphorylation, especially ATM. The modification can happen accidentally during replication fork collapse or in the response to ionizing radiation but also during controlled physiological processes such as V(D)J recombination. γH2AX is a sensitive target for looking at DSBs in After the initial sensing of the DSB by MRN and the activation of ATM, H2AX is phosphorylated, which in turn elicits a sequence of signaling events thought to ultimately cause the activation of nucleases such as Mre11 and CtIP to process the DNA ends and generate ssDNA with 3′ overhangs. ssDNA is bound by RPA, which is subsequently exchanged by Rad51 and Rad51 paralogs. The cells were then incubated with the primary antibody specific for γ-H2AX (Cell Signaling Technologies) at a 1:100 dilution in the DELFIA assay buffer (PerkinElmer) for 2 h at room temperature Gamma H2AX (γH2AX) is the phosphorylated version of histone H2AX and is a marker for double-stranded breaks (DSBs) caused by DNA damage.

The gamma-H2AX signal was present in all nucleated cell types examined. The gamma-H2AX signal and the comet signal were lower in neutrophils compared to monocytes and T-lymphocytes. Here we show that inactivation of the SWI/SNF complexes and downregulation of the catalytic core subunits of the complexes both result in inefficient DNA double-strand break (DSB) repair and increased DNA damage sensitivity as well as a large defect in H2AX phosphorylation (gamma-H2AX) and nuclear focus formation after DNA damage.

In the procedure described, following immunostaining, automated fluorescent imaging and dual-mask spot (part number 8875S) was purchased from Cell Signaling Technology (Danvers, MA).

DNA damage, caused by ionizing radiation, UV-light, or radiomimetic agents, results in rapid phosphorylation of H2A.X at Ser139 by PI3K-like kinases, including ATM, ATR, and DNA-PK (2,3).
