Caspase-9 and -3 activation and PARP cleavage in the different models of hypoxia-ischemia or stroke in adult and neonatal rodent brains. Caspase-9 and caspase-3 activities were determined by fluorogenic LEDH and DEVD substrate cleavage, respectively. The presence of the 89 kDa of the PARP, poly (ADP-ribose) polymerase, a caspase-3 substrate, was described to be an apoptotic feature.
