Figure 3 CJ treatment reduces food intake and weight gain in leptin-deficient mice. There was a significant reduction in the weight of leptin deficient ob/ob mice treated with 300 μg CJ for 7 days followed by 600 μg CJ for 10 additional days. Results are the mean values ± SEM of 8 mice per group and are representative of 2 separate experiments. **P < .01 versus control treatment.

Figure 4 Analysis of Cdc42HeKO mice with Cdc42 ablation in hepatocytes and cholangiocytes. (A) Liver weight/body weight ratio was determined 2 and 4 months after birth. Results are expressed as the mean values ± SD. The number of mice per group is indicated. Statistical differences were determined by the Wilcoxon rank-sum test. *P < .05. (B) Compared with control liver, the liver from a Cdc42HeKO mouse is enlarged and has many nodules of different sizes on its surface (both mice were 10 months old).
