Figure 2. Exercise training enhanced AMPK/SIRT1 anti-aging pathway in D-galactose-induced aging rat hippocampus. The representative protein levels of p-AMPKα, SIRT1, PGC-1α, p-FOXO3a, SOD2 prepared from hippocampi in the control, exercise, aging and aging with exercise rats were measured by Western blotting analysis (n=3). The protein expression folds were normalized with β-actin. * P <0.05, **P<0.01, ***P<0.001, significant differences from the control group. ##P <0.05, ###P <0.01, significant differences from the D-galactose-induced aging group.
