Effects of H₂S on expressions of CHOP, GRP-78, and cleaved caspase-12 in the hippocampus of chronic unpredictable mild stress (CUMS)-exposed rats. After treatment with CUMS for 2 weeks, the rats were further treated with CUMS in the absence or presence of NaHS (30, 100 µmol/kg/d, i.p.) for 2 weeks. GRP-78 (A), CHOP (B), and cleaved caspase-12 (C) in hippocapus of rats were detected by western blot. Values are the mean ± SEM (n = 3/group). ^**P < .01 vs control group; ^##P < .01 vs CUMS group.
