Body weight (BW, A), ad libitum blood glucose levels (B), and blood insulin levels (C) were obtained from 3-mo-old male Bl6 and AKR mice on regular rodent chow (NC). D: blood glucose levels in insulin tolerance test by 0.75 U/kg BW insulin intraperitoneal injection (ip) in C57BL/6J (Bl6, solid) and AKR/J (AKR, open) on NC. E: blood glucose levels in glucose tolerance test by 2 gm/kg BW glucose ip. F: insulin levels in glucose tolerance test by 3 gm/kg BW glucose ip in Bl6 (solid) and AKR (clear) on NC. Data are means ± SE, n = 12–16 (A–C), and 4–5 (D–F). *P < 0.05 vs. Bl6, **P < 0.01 vs. Bl6, ***P < 0.0005 vs. Bl6.
