FIG. 2.

Body weights of WT, PTP-1B^+/−, and PTP-1B^−/− mice. (A and B) Male (A) and female (B) body weight curves of age-matched WT (+/+), PTP-1B^+/− (+/−), and PTP-1B^−/− (−/−) mice fed a chow diet for 15 weeks postweaning. (C and D) Male (C) and female (D) body weight curves of age-matched WT, PTP-1B^+/−, and PTP-1B^−/− mice fed a high-fat diet for 15 weeks postweaning. The number of mice in each group is indicated. Values depict mean ± SEM. An asterisk indicates differences between PTP-1B^−/− and WT groups where P < 0.05.
