Fig. 3. Primary route of cell death induced by BH3-mimetics is via caspase-dependent intrinsic apoptosis.

a MOLM-13 cells were treated with ABT-199 (1 μM) for indicated time prior to analysis of cell death by Annexin-V/FITC staining and flow cytometry. b MOLM-13 or MONO-MAC-6 cells were treated with S63845 (1 μM) for indicated time points prior to the analysis of apoptosis by Annexin-V/FITC staining and flow cytometry. c, d Caspase-3 cleavage was analyzed by Western blotting. Vinculin served as loading control. Arrowheads indicate cleavage fragments of caspase-3. e, f Loss of MMP was measured using TMRM staining and flow cytometry upon treatment with 1 μM of ABT-199 e or 1 μM of S63845 fh. MOLM-13 or MONO-MAC-6 cells were treated with ABT-199 g or S63845 h for 4 h in the presence or absence of 50 μM of the pan-caspase inhibitor zVAD.fmk. Cell death was determined by Annexin-V/FITC staining and flow cytometry. Mean and SD of three independent experiments performed in triplicate are shown. **P < 0.01; ***P < 0.001.
