Figure 3. Dampened circadian rhythms of food intake and hypothalamic clock gene expression in Adipoq-deficient female mice.
(A) Daily profiles of running-wheel activity of wild-type (WT; black) and Adipoq-deficient mice (MT; red) under 12 hr light: 12 hr dark (LD) conditions (n = 6 per group; grey shading indicates dark phase). (B) Daily food intake profiles of WT and MT mice in LD in 6 hr bins (n = 6 per group). (C) Relative light phase food intake of WT and MT mice in LD (n = 6 per group). (D–F) Circadian profiles of running-wheel activity (D; n = 6 per group), food intake (E; n = 6 per group) and relative rest phase food intake (F) of WT and MT mice in constant darkness (DD; n = 6 per group). (G–L) Circadian profiles of MBH clock gene (G–I) and metabolic gene (J–L) mRNA expression in WT and MT mice in DD (n = 3 per time point). All data are means ± SEM. R – rhythmic expression (p<0.05; CircWave); N – non-rhythmic expression (p>0.05); */**/*** - p<0.05/0.01/0.001; 2-way ANOVA with Sidak’s multiple comparisons for B, E; unpaired Student’s t-test for C, F. p-values: (B) 0.0145 (MT vs. WT ZT0-6) and 0.0097 (MT vs. WT ZT12-18), ANOVA dF = F(3, 30)=10.21 (interaction)/95.89 (time)/0.10 (genotype); (C) 0.0325 (MT vs. WT); (E) 0.0206 (MT vs. WT 48–54), ANOVA dF = F(3, 30)=7.63 (interaction)/79.32 (time)/0.30 (genotype); (F) 0.0062 (MT vs. WT).
