Following 8 weeks of diet and exercise interventions, all mice were assessed for their metabolic function by GTT, ITT, and skeletal muscle response of Akt and AS160 phosphorylation to injection of insulin measured by Western blot. (A–C) HOMA-IR taken after an overnight fast for baseline glucose and insulin. (D and E) GTT from 0–120 min and calculated AUC; colored * indicates significant difference from NC-SED. (F and G) ITT from 0–60 min and calculated AUC; colored * indicates significant difference from NC-SED. (H–N) pAkt stimulation, AS160 S318, and AS160 T642 in hindlimb muscles before and after insulin injection and the pre–post ∆ in phosphorylation. (O and P) Total and phosphorylated 4E-BP1.
