Figure 4. MC4R and NPY are necessary for up regulation of Nr1i3 and its target genes during fasting.
Expression of various genes in the liver was measured via QPCR and normalized to Rn18S expression in WT (n = 17, n = 10), Npy−/− (n = 10, n = 7) and pair-fed Mc4r−/− PF (n = 7, n = 7) and DKO PF (n = 9, n = 7) mice. A, Expression of Thrsp and Fasn. B, Expression of Nr1i3 and its classical target gene, Cyp2b10. C, Expression of the Nr1i3-target genes involved in hepatic TH metabolism: Sult1a1, Sult2a1, Sult1d1 and Ugt1a1. D, Expression of Thrβ1. In all panels, data are presented as mean ± SEM. Significance was measured with 2-way ANOVA with Bonferroni post hoc test. * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
