Body weight, body composition, and whole body glucose metabolism in low fat diet (LFD)-fed WT and Ctrp12 (+/−) male mice. A: body weight gain over time in WT (+/+) and Ctrp12 (+/−) littermates. B: NMR measurements of total lean and fat mass in WT and Ctrp12 (+/−) mice at 20 wk of age. C: blood glucose levels of WT and Ctrp12 (+/−) at 0, 15, 30, 60, and 120 min following glucose injection in a glucose tolerance test (GTT). D: serum insulin levels of WT and Ctrp12 (+/−) mice at 0 and 15 min postglucose injection. E: blood glucose levels of WT and Ctrp12 (+/−) mice at 0, 15, 30, 45, 60, and 90 min following 1 U/kg body wt insulin injection in an insulin tolerance test (ITT). F: blood glucose levels of WT and Ctrp12 (+/−) mice at 0, 15, 30, 60, 120, and 180 min following injection of 1 g/kg body wt sodium pyruvate in a pyruvate tolerance test (PTT). (n = 9–14 per group.)
