Cardiomyocyte mitochondrial membrane potential (MMP) in WT and Akt2 knockout (AKTKO) mice treated with or without propionate (0.3 g/kg, i.p.) for 7 days. MMP was measured using JC-1 fluorochrome (ratio of red to green fluorescence). (a) MMP at 30 min; (b) MMP at 90 min. Mean ± SEM, isolations, *P < 0.05 versus WT group, and #P < 0.05 versus AKTKO group.
