 Loss of MCL-1 function modulates BAK expression. SKBR3 cells were treated with MCL-1 siRNA (#5), scrambled siRNA (Sc; both 20 nmol/L) or the MCL-1 inhibitor A-1210477 for 8 hours and the effect on MCL-1, PARP, and BAK determined by Western blot analysis (A) or by RT-PCR (B).

 BCL-XL limits the efficacy of A-1210477 to a greater extent than BCL-2. SKBR3 cells overexpressing BCL-XL or BCL-2 were treated with A-1210477 for 24 hours and the percentage of apoptosis determined from the sub-G0–G1 DNA content of DNA cell-cycle histograms and compared with vector control (Vct Ctrl) or parental cell lines (wild-type, WT). |
