Effects of tannase-treated catechin on mRNA levels of (a) SOD, (b) CAT, and (c) GST in aged mice. Each value represents the mean ± standard error (SE) for each group (n = 8). Different letters indicate significant differences atp < 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); SOD: superoxide dismutase; CAT: catalase; GST: glutathione S-transferase.
