SMC1 depletion impairs the repair of DSBs in G2-phase cells. (A) γH2AX and CENP-F staining in SMC1-depleted cells 2 h after 1 Gy X-irradiation. (B) Time course for the loss of 1 Gy X-ray-induced γH2AX foci in G1- (CENP-F negative) and late S/G2-phase cells (CENP-F strongly positive). (C) 53BP1, Cyclin A and BrdU staining in SMC1-depleted cells 2 h after 1 Gy X-irradiation. (D) Time course for the loss of 1 Gy X-ray-induced 53BP1 foci in G1 (BrdU-negative cyclin A-negative) and G2-phase cells (BrdU-negative cyclin A positive). Error bars are standard errors of the mean from two to three experiments.
