Longitudinal assessment of systemic and tissue-specific insulin sensitivity in CD and HFD mice
(A) Blood glucose during ITT (0.75 U/kg insulin) (N ≥ 7 mice/group). The ratios of AUC for HFD versus CD are presented at the top of each graph.
(B) Hyperinsulinemic-euglycemic clamp tests (N ≥ 6 mice/group).
(C and D) Immunoblot (C) and quantification (D) of Akt (Ser473) phosphorylation status relative to total Akt and GSK-3α/β (Ser21/9) phosphorylation status relative to total GSK-3α/β in liver (N = 4–6 mice/group).
All data are expressed as mean ± SEM and analyzed using unpaired two-tailed t test. ∗p < 0.05, ∗∗p < 0.01. See also Figure S3.
