Figure 3. Leptin sensitivity in a 12-day infusion.
A. Body weight of wild-type animals that received a leptin (red) or PBS (black) infusion for 12-days (gray block). B. Body weight of ob-norm animals that received a leptin (red) or PBS (black) infusion for 12-days (gray block). C. Difference in weight loss between leptin and vehicle for each cohort over the 12-day leptin infusion. Values are expressed as percentage change in body weight. D. Average daily food intake during the 12-day infusion for animals in each cohort.
