Lipoprotein lipase deficiency and CETP in streptozotocin-treated apoB-expressing mice.

Both hyperglycemia and hyperlipidemia have been postulated to increase atherosclerosis in patients with diabetes mellitus. To study the effects of diabetes on lipoprotein profiles and atherosclerosis in a rodent model, we crossed mice that express human apolipoprotein B ( HuB), mice that have a heterozygous deletion of lipoprotein lipase (LPL1), and transgenic mice expressing human cholesteryl ester transfer protein (CETP). Lipoprotein profiles due to each genetic modification were assessed while mice were consuming a Western type diet. Fast-protein liquid chromatography analysis of plasma samples showed that HuB/LPL1 mice had increased VLDL triglyceride, and HuB/LPL1/CETP mice had decreased HDL and increased VLDL and IDL/LDL. All strains of mice were made diabetic using streptozotocin (STZ); diabetes did not alter lipid profiles or atherosclerosis in HuB or HuB/LPL1/CETP mice. In contrast, STZ-treated HuB/LPL1 mice were more diabetic, severely hyperlipidemic due to increased cholesterol and triglyceride in VLDL and IDL/LDL, and had more atherosclerosis.[1]
