Abstract：
:Induction of apoptosis in Hep3B hepatoma cells by transforming growth factor beta 1 (TGF-beta 1) was accompanied by the activation of interleukin-1-beta-converting-enzyme-like proteases, which have recently been renamed as caspases. The caspase inhibitor ZVAD-FMK, which has a broader specificity for caspase family proteases, blocked TGF-beta 1-induced apoptosis in a concentration-dependent manner. The caspases in this apoptotic process were further characterized by using a more specific caspase inhibitor, DEVD-FMK, for CPP32-like (caspase-3-like) proteases. Our results demonstrated that CPP32-like proteases were activated during apoptosis triggered by TGF-beta 1. Enhancement of CPP32-like activity was clearly detected in TGF-beta 1-treated Hep3B cells. Furthermore, cleavage of poly(ADP-ribose) polymerase, an in vivo substrate for CPP32, in these cells was confirmed by immunoblotting. Thus, we suggest that CPP32-like proteases participate in apoptotic cell death induced by TGF-beta 1.
