A–F: Relative mRNA expression from various brain regions of Fabps in Rev-erbα KO vs. WT mice. Levels of Fabp3 mRNA are not affected by loss of Rev-erbα, while lower levels of Fabp5 mRNA are observed in Hypothalamus (B), Cerebellum (C), and VTA (F) based on Rev-erbα deficiency compared to WT. Fabp7 mRNA, however, shows significant increases in expression in Rev-erbα KO compared to WT in all brain regions studied. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, N = 3–5 per group, Student’s t-test.
