A and B, Gastrocnemius muscle PPARδ (A) and SIRT1 (B) protein levels in sedentary mice (SED) and mice exercised for 20 minutes (EX) and analyzed 3 hours later. In each panel, the overall significance of genotype, treatment, or the interaction of these 2 factors determined by two-way ANOVA is shown; bars with different superscripts are significantly different at P < .05. Sample sizes were 6 to 9 mice in each genotype per treatment group. Bars represent means ± SEM. Representative Western blots are shown below the respective graphs; bands shown for each species are compiled from different regions of the same blot.
