1 Since caspase-3 may be activated by initiator caspase-9 and -8, it is significant to show that such caspase activation cascade is induced by 4 microM DAU and TT bisquinones at 6 h in HL-60-S cells. Daunorubicin caspase 9 Homo sapiens
2 The release of mitochondrial Cyt c is also detected within 6 h in HL-60-S cells treated with 4 microM DAU or TT bisquinones, a finding consistent with the fact that Cyt c is the apoptotic trigger that activates caspase-9. Daunorubicin caspase 9 Homo sapiens
