Protein levels for p21 and GADD45a in mouse skeletal muscle. (A) Representative western blot for p21 and GADD45a staining in young, old and old CR skeletal muscle. (B) Expression ratio information on protein levels (n = 3 and n = 4 for p21 and Gadd45a respectively for each age and diet). One-tailed Student's t-test; *P < 0.05, **P < 0.005 (young verses old), P < 0.005 (old versus old CR).
