Excessive production of triglyceride-rich VLDL, which can result from dietary overindulgence, underlies metabolic syndrome--a combination of disorders including high blood pressure, obesity, high triglyceride, and insulin resistance--and places individuals at increased risk of developing cardiovascular disease and type 2 diabetes. However, the link between VLDL overproduction and insulin resist...

Abetalipoproteinemia is a rare autosomal recessive disease characterized by low lipid levels and by the absence of apoB-containing lipoproteins. It is the consequence of microsomal triglyceride transfer protein (MTTP) deficiency. We report two patients with new MTTP mutations. We studied their functional consequences on the triglyceride transfer function using duodenal biopsies. We transfected ...

AIM 2,3,5,4'-Tetrahydroxy-stilbene-2-O-β-d-glucoside (TSG), a natural stilbene, shows great activities in hepatic lipid regulation, especially for hepatic triglyceride lowering. However, information about its mechanisms on biosynthesis and degradation of triglyceride is still limited. This research pays close attention to clarify the mechanism of TSG on prevention of hepatic lipid accumulation....

Carbon tetrachloride (CCl(4)) interferes with triglyceride secretion and causes steatosis, fibrosis, and necrosis. In mice, CCl(4) decreased plasma triglyceride-rich lipoproteins, increased cellular lipids, and reduced microsomal triglyceride transfer protein (MTP) without diminishing mRNA levels. Similarly, CCl(4) decreased apoB-lipoprotein production and MTP activity but had no effect on mRNA...
