Research Abstract |
Non-apoptotic cell death in ischemic heart disease is considered to be one of the important therapeutic targets, however, the detailed mechanisms of this cell death process is not clear. In this study, we found that hypoxic myocyte death was independent of caspases and involved with calcium-independent phospholipase A_2 (iPLA_2). The potent cardioprotective corticotropin-releasing hormone (CRH), urocortin and peptide hormone leptin suppress caspase-independent, non-apoptotic death in myocytes exposed to ischemia. On the other hand, autophagy prevents ischemic injury dependent on glucose concentration and is required for cardioprotective activity of 17-β-estradiol.
