Effects of tannase-treated catechin on the protein expression of FOXO3a, myostatin, MuRF-1, and atrogin-1 in aged mice. Each value represents the mean ± standard error (SE) for each group (n = 8). Different letters indicate significant differences at p < 0.05 according to Tukey's test. EC: epicatechin (2 mg/kg); T₁: middle-concentration tannase-converted green tea extract (20 mg/kg); T₂: high-concentration tannase-converted green tea extract (40 mg/kg); FOXO3a: forkhead box protein O3a; MuRF-1: muscle RING finger protein-1.
