| abstractText | Angiopoietin-like protein family 4 (Angptl4) has been shown to regulate lipoprotein metabolism through the inhibition of lipoprotein lipase (LPL). In familial hypercholesterolemia (FH), individuals lacking low-density lipoprotein receptor (LDLR) present not only hypercholesterolemia, but also increased plasma triglyceride (TG)-rich lipoprotein remnants, and develop atherosclerosis. In addition, the most common type of dyslipidemia in individuals with diabetes is increased TG levels. We first generated LDLR(-/-)Angptl4(-/-) mice to study the effect of Angptl4 deficiency on the lipid metabolism. Fasting total cholesterol, VLDL-C, LDL-C, HDL-C and TG levels were decreased in LDLR(-/-)Angptl4(-/-) mice compared with LDLR(-/-)Angptl4(+/+) mice. In particular, post olive oil-loaded TG excursion were largely attenuated in LDLR(-/-)Angptl4(-/-) mice compared with LDLR(-/-)Angptl4(+/+) mice. We next introduced diabetes by streptozotocin (STZ) treatment in Angptl4(-/-) mice and examined the impacts of Angptl4 deficiency. Compared with diabetic Angptl4(+/+) mice, diabetic Angptl4(-/-) mice showed the improvement of fasting and postprandial hypertriglyceridemia as well. Thus, targeted silencing of Angptl4 offers a potential therapeutic strategy for the treatment of dyslipidemia in individuals with FH and insulin deficient diabetes. |
