(A–D) Metabolic chambers were utilized to determine (A) food consumption, (B) Respiratory exchange ratio (RER), (C) Spontaneous activity, and (D) Energy expenditure in (left) female and (right) male mice lacking hepatic Rictor (L-RKO) and their wild-type (WT) littermates of the indicated surgical treatments at 12 months of age. The overall effect of genotype (RKO), gonadectomy (OVX or CAST), and the interaction represent the p-value from a two-way ANOVA conducted separately for the light and dark cycles; *=p < 0.05 from a Holm-Sidak post-test examining the effect of parameters identified as significant in the two-way ANOVA (n = Females, 10 mice/group; Males, WT Sham = 11 mice; WT CAST = 10 mice, L-RKO Sham = 9 mice, L-RKO CAST = 8 mice). Error bars represent SEM.
