Popis: We have reported that obese leptin-deficient mice (ob/ob) lacking the low-density lipoprotein receptor (LDLR(-/-)) develop severe hyperlipidemia and spontaneous atherosclerosis. In the present study, we show that obese leptin receptor-deficient mice (db/db) lacking LDLR have a similar phenotype, even in the presence of elevated plasma leptin levels. We investigated the mechanism for the hyperlipidemia in obese LDLR(-/-) mice by comparing lipoprotein production and clearance rates in C57BL/6, ob/ob, LDLR(-/-) and ob/ob;LDLR(-/-) mice. Hepatic triglyceride production rates were equally increased ( approximately 1.4-fold, P
