Figure 4.Effects of exercise training on inflammatory proteins. The representative protein levels of TNFα, p-NFκB, iNOS and COX2 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<0.01, ***P<0.001, significant differences from the control group. ##P <0.05, significant differences from the D-galactose-induced aging group.
