2.4.2.12 | physiological function |
cardiac-specific overexpression of Nampt in transgenic mice increases NAD+ content in the heart, prevents downregulation of Nampt, and reduces the size of myocardial infarction and apoptosis in response to prolonged ischemia and ischemia/reperfusion. Upregulation of Nampt significantly increases NAD+ and ATP concentrations, whereas downregulation of Nampt significantly decreases them. Expression of Nampt in the heart is significantly decreased by ischemia, ischemia/reperfusion and pressure overload. Downregulation of Nampt increases caspase 3 cleavage, cytochrome c release, and TUNEL-positive cells, which are inhibited in the presence of Bcl-xL, but do not increase hairpin 2-positive cells, suggesting that endogenous Nampt negatively regulates apoptosis but not necrosis. Downregulation of Nampt also impairs autophagic flux |
