Abstract:BackgroundOversupply of fatty acids (FAs) to cardiomyocytes (CMs) is associated with increased ceramide content and elevated the risk of lipotoxic cardiomyopathy. Here we investigate the role of ceramide accumulation on mitochondrial function and mitophagy in cardiac lipotoxicity using CMs derived from human-induced pluripotent stem cells (h-iPSCs). Methods and resultsMature CMs derived from h-iPSCs exposed to the diabetic-like environment or transfected with plasmids overexpressing serine-palmitoyltransferase… Show more
