Effects of chronic psychosocial stress and concomitant citalopram treatment on GFAP and NDRG2 expression in the hippocampus (Western blot analysis; β-actin as reference protein). Representative blotting membranes are shown beneath the bar graphs. Results are presented as percentages of the mean control value (mean ± SEM). Statistical differences resulting from one-way ANOVA with Tukey’s multiple comparison test: *P < 0.05, **P < 0.01 vs. control. Statistical difference to control as determined with the t test: ^# P < 0.05; ^### P < 0.001. C control, S stress, SC stress citalopram, CC control citalopram
