Female B6.V-lepob obese mice (n=24) aged 7 weeks were obtained from The Jackson Laboratory (Bar Harbor, ME). Upon arrival, mice were placed on a standard chow diet and were allowed to acclimate fro 1 week before starting the experiment. For leptin treatments, mice received daily intraperitoneal injections of either recombinant mouse leptin (R&D Systems, Minneapolis, MN) (n=12) at a dose of 5 µg/g body weight or with saline as a control (n=12) for 4 weeks. At 12 weeks of age, mice were fasted overnight with free access to water. The following morning the mice underwent cholecystectomy. Three gallbladders were pooled and total RNA was isolated.
