Figure 4:Western blot results for proteins of the NEP molecule from mouse hippocampus (Hip) and frontal cortex (Cor). The vehicle was saline; GAPDH was used as a loading control. All experiments were performed at least in triplicate (data are presented as the mean ± SEM of three independent experiments), *P<0.05 vs. Con group; #P<0.05 vs. D-Gal group.
