摘要: We have previously shown that hypoxia results in increased activity of caspase-9, caspase-3 and fragmentation nuclear DNA the cerebral cortex newborn piglets. The present study tested hypothesis mechanism during piglets is mediated by caspase-9-dependent activation. Newborn were randomly assigned to normoxic, hypoxic, hypoxic pretreated with a highly selective caspase-9 inhibitor, Z-LEHD-FMK groups. data showed tissue expression caspase-activated DNase (CAD) protein nucleus DNA. A pretreatment attenuated CAD Based on these results, we conclude which was fragmented activation consequence
