Partial cloning and localisation of leptin and its receptor in the one-humped camel (Camelus dromedarius)

Based on the studies and results presented here, leptin and its receptor were expressed by adipose tissue, mammary alveolar epithelial cells, liver hepatocytes, and the lining epithelium of the bile duct of the one-humped camel (Camelus dromedarius). Our observations support the biological importance of leptin in the mammary gland as well as the likely local effect of leptin on the peripheral tissues. We suggest that there may be an association between hepatic leptin and the lipogenic activity of the liver in the dromedary camel. (C) 2004 Elsevier Ltd. All rights reserved.
