Previous studies have shown that pseudolaric acid B (PB) would cause apoptosis in human tumor cell lines. However, the mechanisms of PB induced apoptosis are still unclear. In the present study, the mechanisms of PB induced apoptosis in the human hepatocellular carcinoma Bel-7402 cell line were investigated by measuring cell viability, rate of apoptosis, cell cycle, detecting DNA fragmentation, and measuring caspase-3 activation. The results indicated that PB inhibited Bel-7402 cell viability and induced cell death by causing DNA fragmentation, up regulating the early and late apoptotic rates, activating caspase-3 protein, and detaining the cell cycle in the G2/M phases. Additionally, PB-induced apoptosis was a dose- and time-dependent manner. These observations suggest that PB-induced apoptosis occurs through a caspase-dependent pathway and detains the cell cycle in the G2/M phase.
