Effects of RVD-hemopressin ( α) on feeding and body weight after standard or cafeteria diet in rats
Palatability and variety of foods are major reasons for hedonic eating, and hence for obesity. Hemopressin, a hemoglobin α chain-derived peptide, plays antagonist/inverse agonist role on cannabinoid (CB)1 receptors, while RVD-hemopressin(α)[RVD-hp(α)], a N-terminally extended form of hemopressin, has been reported as an allosteric modulator of CB1 and CB2 receptors.We investigated the effects of 14 daily intraperit oneal injections of RVD-hp(α), in Sprague-Dawley rats fed a highly palatable cafeteria-style (CAF) diet (30% fat, 56% carbohydrate, 14% protein; 4.20 kcal/g) compared to standard laboratory chow (STD) food (3.5% fat, 63% carbohydrate, 14% protein, 19.5% other components without caloric value; 3.2 0 kcal).
