(A) Transmission electron micrographs of cardiac sections from SIRT3-KO mice and WT controls six weeks after sham or TAC. (×20,000). (B) Heart extracts from SIRT3-KO mice and WT controls were analyzed for triglyceride and cholesterol esters. (C) Palmitate oxidation rates in perfused hearts from WT and SIRT3-KO mice after sham or TAC. The data are presented as the means ± SEM of three independent experiments. *P<0.05,**P<0.01.
