(A-B) TGR5 CRISPR and ALDH2 CRISPR pretreatment reversed the neurobehavioral benefits of INT-777 at 24 h after SAH, n=6 per group. (C-E) Representative western blot bands and densitometric quantification of TGR5 and ALDH2 demonstrated the efficacy of CRISPR knockout in naive and SAH rats, n=4 per group. Vehicle: 10% dimethyl sulfide. Data was represented as mean ± SD. *P<0.05 vs. Sham group; @P<0.05 vs. SAH+Vehicle group; &P<0.05 vs. SAH+scr CRISPR group; #P<0.05 vs. SAH+scr CRISPR group; One-way ANOVA, Tukey’s post hoc test; scr CRISPR, scrambled CRISPR; KO CRISPR, Knockout CRISPR.
