Western blot indicated the protein expression level in the mouse hippocampus. A. Lane 1, 2, 3, and 4 represent the protein expression levels in the sham group, PTSD group, PTSD+K group and PTSD+W group, respectively. B-H denotes the relative protein expression levels of 5-HT2A receptor, 5HT1A receptor, ERK1, ERK2, pERK1, pERK2, and c-Myc in the four experimental groups. Data were presented as mean ± SEM through ANOVA. Groups were compared by performing Bonferroni’s test, n = 4. ^*P < 0.05 vs. the sham group; ^#P < 0.05, ^##P < 0.01 vs. the PTSD group; ^sP < 0.05, ^ssP < 0.01, ^sssP < 0.001 vs. the PTSD+K group.
