- Abstract
- We previously reported that apicidin arrested human cancer cell growth through selective induction of p21(WAF1/Cip1). In this study, the apoptotic potential of apicidin and its mechanism in HL60 cells was investigated. Treatment of HL60 cells with apicidin caused a decrease in viable cell number in a dose-dependent manner and an increase in DNA fragmentation, nuclear morphological change, and apoptotic body formation, concomitant with progressive accumulation of hyper-acetylated histone H4. In addition, apicidin converted the procaspase-3 form to catalytically active effector protease, resulting in subsequent cleavages of poly(ADP-ribose) polymerase and p21(WAF1/Cip1). Incubation of HL60 cells with z-DEVD-fmk, a caspase-3 inhibitor, almost completely abrogated apicidin-induced activation of caspase-3, DNA fragmentation, and cleavages of poly(ADP-ribose) polymerase and p21(WAF1/Cip1). Moreover, these effects were preceded by an increase in translocation of Bax into the mitochondria, resulting in the release of cytochrome c and cleavage of procaspase-9. The addition of cycloheximide greatly inhibited activation of caspase-3 by apicidin by interfering with cleavage of procaspase-3 and DNA fragmentation, suggesting that apicidin-induced apoptosis was dependent on de novo protein synthesis. Consistent with these resu
