1 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). apicidin caspase 3 Homo sapiens
2 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). apicidin caspase 3 Homo sapiens
3 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). apicidin caspase 3 Homo sapiens
4 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. apicidin caspase 3 Homo sapiens
5 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. apicidin caspase 3 Homo sapiens
6 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. apicidin caspase 3 Homo sapiens
7 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. apicidin caspase 3 Homo sapiens
8 Preincubation with NOK-1 monoclonal antibody, which prevents the Fas-Fas ligand interaction and is inhibitory to Fas signaling, interfered with apicidin-induced translocation of Bax, cytochrome c release, cleavage of procaspase-3, and DNA fragmentation. apicidin caspase 3 Homo sapiens
9 Taken together, the results suggest that apicidin might induce apoptosis through selective induction of Fas/Fas ligand, resulting in the release of cytochrome c from the mitochondria to the cytosol and subsequent activation of caspase-9 and caspase-3. apicidin caspase 3 Homo sapiens
