FIG. 5.

Muscle lipid species. G6PDH activity (A) and FAS activity (B). C: TAGs. D: DAGs. E: Ceramide. F: Phosphatidylcholine. G: Phosphatidylethanolamine. H: Sphingosine. All values are expressed as mean ± SE (n = 8 per group). @Effect of genotype (wild-type [wt] vs. MPGC-1α TG). #Effect of training (sedentary [sed] vs. exercised [ex]). xGenotype times training interaction as assessed by ANOVA. Comparison between two individual groups: *Effects of training (sed vs. ex) and §Genotype (wt vs. MPGC-1α TG mice) were assessed by t test. One symbol indicates P < 0.05, two symbols indicate P < 0.01, and three symbols indicate P < 0.001.
