miR-9-5p expression and sucrose preference measure in CMS rats. (A) qPCR analysis of miR-9-5p expression in the HPC. Tukey's post-hoc test: *p < 0.05 vs CNT; ^#p < 0.05 vs CMS-V; n = 7–10. Data are reported as means ± S.E.M. (B) Sucrose preference test of CNT and CMS rats at Day +35 of CMS, 24 h after KET/VEH treatment n = CNT 10; CMS-R 10; CMS-V 10; CMS-V + KET 8. Tukey's post-hoc test: ***p < 0.001 vs CNT, ^##p < 0.01 vs CMS-V, ^§§§p < 0.001 vs CMS-R. Data are reported as means ± S.E.M. (C) Correlation between miR-9-5p HPC expression and the sucrose preference in CMS rats. Pearson's r, r = 0.3677, p < 0.05.
