Dietary epicatechin reversed age-associated protein expressions in SkM of aged mice. Skeletal muscle samples (quadriceps) were collected at 37 wk in the EC and OC groups or at 12 mo of age in the YC group (n = 12/group). Total actin (all 6 isoforms) (B) or PPARγ (D) protein expression was measured by Western blot and normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) content. The mRNA expression of actin (A) or PPARγ (C) was obtained from the RNA sequencing as described in Fig. 4. ^#P < 0.05 EC vs. YC, *P < 0.05 EC vs. (n = 8/group).
