Figure 2. Expression of molecular markers in young and aged rats. n = 3. (A–C) Expression of NR1 in mPFC and hippocampus by IHC (A, B), and western blotting (C). (D–F) Expression of BDNF in mPFC and hippocampus by IHC (D, E), and western blotting (F). (G–I) Expression of AGE in mPFC and hippocampus by IHC (G, H), and western blotting (I). (J–L) Expression of RAGE in mPFC and hippocampus by IHC (J–K), and western blotting (L). Error bars represent the SEM. * P < 0.05, ** P < 0.01.
