Abstract
Heart ischemia is a hypoxia related disease. NOX2 and HIF-1α proteins were increased in cardiomyocytes after acute myocardial infarction. However, the relationship of the hypoxia-induced HIF-1α. NOX2-derived oxidative stress and apoptosis in cardiomyocyte remains unclear. In the current study, we use NOX2 antisense strategy to investigate the role of NOX2 in hypoxia-induced oxidative stress and apoptosis in rat cardiomyocytes. Here, we show that transduction of ADV-NOX2-AS induces potent silencing of NOX2 in cardiomyocytes, and resulting in attenuation of hypoxia-induced oxidative stress and apoptosis. This study indicates the potential of antisense-based therapies and validates NOX2 as a potent therapeutic candidate for heart ischemia.
