AMPK: energy sensor and survival mechanism in the ischemic heart

AMP-activated protein kinase (AMPK) is a critical regulator of cellular metabolism and plays an important role in diabetes, cancer, and vascular disease. In the heart, AMPK activation is an essential component of the adaptive response to cardiomyocyte stress that occurs during myocardial ischemia. During ischemia-reperfusion, AMPK activation modulates glucose and fatty acid metabolism, mitochondrial function, endoplasmic reticulum (ER) stress,...
