Data are expressed as Means ± SEM, n = 8-12 per group.
p < 0.05 and < 0.01 vs non-diabetic control group (Experiment 2) and vs corresponding groups of mice fed normal chow (Experiment 3).
p < 0.05 and < 0.01 vs untreated diabetic group (Experiment 2) and vs HFD-fed wild-type mice (Experiment 3).
0.0599 vs untreated diabetic group.
NC – normal chow, HFD- high-fat diet.
