![Western Blot: Histone H2AX Antibody [NB100-638] - Knockdown of CAPER induces DSB proteins ATM & H2AX & leads to apoptosis in MDA-MB-231 cells(A) H2AX phosphorylation on ser139 is significantly increased (upper right quadrant population) in MDA-MB-231 cells after CAPER knockdown as represented by Muse Cell Analyzer plots (3-fold, p < 0.001, n = 3). (B) The increase in gamma H2AX was also validated through western blot analysis (2.5-fold, p < 0.01, n = 3). ATM phosphorylation on serine1981 is significantly upregulated after knockdown of CAPER expression (5-fold, p < 0.05, n = 3). (C) CAPER knockdown resulted in an increased level of caspase-3/7 activation through decreasing live cells (1.2-fold, p < 0.001, n = 3), while increasing apoptotic (7.5-fold, p < 0.001, n = 3), apoptotic/dead (6.5-fold, p < 0.001, n = 3), & dead (3-fold, p < 0.05, n = 3) cell populations. Interestingly, MDA-MB-231 cells expressing CAPER knockdown displayed no significant changes in any of the phases of the cell cycle (p = NS, n = 8, for G1, S & G2/M phases) compared to CTL shRNA (Figure 7C right panels).
