Apoptosis induced by ER stress in the hippocampus. (A) Representative immunoblot for cleaved caspase-12, cleaved caspase-3 and GAPDH. (B) Relative density analysis of the cleaved caspase-12 and cleaved caspase-3 protein bands. The relative density is expressed as the ratio (cleaved caspase-12/GAPDH; cleaved caspase-3/GAPDH; n = 5). (C) Photomicrographs of TUNEL-positive cells in the hippocampal CA1 of all treated groups (magnification 200×). Scale bar = 100 μm. (D) Hippocampal CA1 neurons apopotosis index in each group (n = 8). Data were expressed as mean ± SD. *P < 0.05, **P < 0.01 vs. control group. #P < 0.05, ##P < 0.01.
