Abstract
Article highlights: Cytochrome c oxidase subunit 6A2 (COX6A2) expression is increased in diabetic islets. Increased COX6A2 promotes β-cell apoptosis via modulation of cyclophilin D-mediated cytochrome c release from mitochondria to the cytoplasm. Carbohydrate-responsive element-binding protein epigenetically regulates COX6A2 expression in β-cells. Roux-en-Y gastric bypass reduces COX6A2 expression by regulating the glucagon-like peptide 1/cAMP-dependent protein kinase/carbohydrate-responsive element-binding protein signaling pathway.
