(a) Image-based cytometry reveals increased gamma H2AX formation after 72 h SNRPA1 knockdown in U2OS cells. SNRPA1 knockdown effciency is shown in the bar graph. U2OS cells transiently (b) or stably (c) expressing SNRPA1-GFP were microirradiated & protein recruitment followed in real-time. For transcription & splicing inhibition cells were pretreated with DRB (50 μM) or SSA (100 nM) for at least 1 h before damage induction. Representative confocal images & recruitment kinetics are shown. (d) As in (b & c) but in cells stably expressing SF3A3-GFP.

U2OS cells were transfected with control or SNRPA1 siRNA & 48 or 72 h later microirradiated, fixed after indicated repair times & stained for gamma H2AX, RAD51 & BRCA1. Representative confocal images & percentage of cells displaying RAD51 & BRCA1 recruitment are shown. Scale bar 5 or 10 μM (i).

For each condition, more than 400 cells were analyzed. (c) After indicated time periods of SNRPA1 knockdown, cells were collected & analyzed by western blotting. Forty-eight hours after SNRPA1 depletion, protein expression levels of RAD51 & Chk1 were already reduced. At 24 h after siSNRPA1 transfection, gamma H2AX levels transiently increased & then declined. The error bars represent s.e.m. from three independent experiments (n=3). Statistically significant differences between cells treated with control or splicing factor siRNA were determined using Student's t-test, *P<0.05, **P<0.01. Scale bar is 10 μm.
