Cells were treated with MBIC in a dose-dependent manner for 24 h. Cells were harvested, lysed and applied for Western blot analysis as described previously [10 (link)]. The primary antibodies that were used in this study included: anti-p53, anti-survivin, anti-phospho-survivin (anti-p-survivin), anti-Cdk1, anti-cyclin B1, anti-Bax, anti-caspase-3, anti-caspase-7, anti-caspase-9 (1:1000) (Cell Signaling Technology, USA) and mouse anti-β-actin (1:40000) (Sigma-Aldrich, St. Louis, MO, USA) antibodies. Western blot images were quantified and processed by ImageJ software (NIH, USA). Each experiment was done in triplicate.
