摘要
Apoptosis is an important contributor to heart diseases in which ischemia and hypoxia are key elements. Previous studies have shown that cardiomyocyte can be protected from ischemia-reperfusion (I/R) injury by heat shock proteins (HSP). However, to date the protective roles of HSP against cardiomyocyte apoptosis has not been confirmed.The present study was designed to explore the effects of mitochondrial pathway in the protective role of heat shock protein against cardiomyocyte apoptosis Cardiomyocyte apoptosis was induced by in vivo mouse heart ischemia-reperfusion (I/R) injury and by hydrogen peroxide (H2O2, 0.5mM) in cultured neonatal rat cardiomyocyte and C2C12 cell line. (2) Cardilmyocyte apoptosis was
