Improved glucose tolerance and insulin sensitivity in the Mgat2 -deficient mice on an HFD. Time course of changes in blood glucose (A) and plasma insulin (B) after an oral challenge of 2 g/kg glucose. (C) HOMA-IR was calculated. Each bar represents mean ± SEM. n = 6–15 per group. *P < 0.05, **P < 0.01, ***P < 0.001 vs. HFD +/+. #P < 0.05, ###P < 0.001 vs. ND +/+.
