AMP-activated protein kinase (AMPK) activation has an antiapoptotic effect in endothelial cells, but the mechanisms involved remain unclear. Here, we investigated whether AMPK activation could inhibit palmitate-induced apoptosis through suppression of reactive oxygen species (ROS) production in bovine aortic endothelial cells. Palmitate increases ROS generation and thereby p38 activation, which leads to apoptosis in bovine aortic endothelial cells. The AMPK activator 5-aminoimidazole-4-carboxamide-1-β-
