H(2)O(2)-Activated Mitochondrial Phospholipase iPLA(2)γ Prevents Lipotoxic Oxidative Stress in Synergy with UCP2, Amplifies Signaling via G-Protein–Coupled Receptor GPR40, and Regulates Insulin Secretion in Pancreatic β-Cells

Aims: Pancreatic β-cell chronic lipotoxicity evolves from acute free fatty acid (FA)–mediated oxidative stress, unprotected by antioxidant mechanisms. Since mitochondrial uncoupling protein-2 (UCP2) plays antioxidant and insulin-regulating roles in pancreatic β-cells, we tested our hypothesis, that...
