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....

Serum triglyceride levels were significantly raised in 37 markedly obese females, especially in the younger subjects; cholesterol and phospholipid levels were normal. Considerable variation in triglyceride levels of equally obese subjects was observed. No relationship was noted between triglyceride levels and the pattern of subcutaneous fat distribution. It is suggested that the high triglyceri...

Chronic renal failure (CRF) is associated with hypertriglyceridemia and elevated plasma VLDL and IDL concentrations. These events can be due to either increased production or depressed catabolism of triglyceride-rich lipoproteins. Several studies have documented downregulation of lipoprotein lipase, hepatic triglyceride lipase, and the VLDL receptor, leading to depressed clearance and elevated ...

Adipose differentiation-related protein (ADRP) is a lipid droplet-associated protein that is expressed in various tissues. In mice treated with the peroxisome proliferator-activated receptor alpha (PPARalpha) agonist Wy14,643 (Wy), hepatic mRNA and protein levels of ADRP as well as hepatic triglyceride content increased. Also in primary mouse hepatocytes, Wy increased ADRP expression and intrac...

Because the association of hypertriglyceridemia and premature atherosclerosis is not due to the direct effects of the triglyceride molecule itself, we studied the effects of increased plasma triglyceride-rich lipoproteins on the composition and structure of low density lipoprotein (LDL) and high density lipoprotein (HDL). We found profound changes in the core and surface domains of both lipopro...

The liver secretes triglyceride-rich VLDLs, and the triglycerides in these particles are taken up by peripheral tissues, mainly heart, skeletal muscle, and adipose tissue. Blocking hepatic VLDL secretion interferes with the delivery of liver-derived triglycerides to peripheral tissues and results in an accumulation of triglycerides in the liver. However, it is unclear how interfering with hepat...

Triglyceride rich-lipoproteins induce triglyceride accumulation in macrophages, leading to foam cell formation. The correlation between cell triglyceride accumulation and lipoprotein lipase (LPL) secretion in murine macrophages and the role that LPL plays in the accumulation process were examined. LPL secretion is defined as the extracellular LPL activity that accumulates during a 4-hour incuba...

To determine the relation between plasma triglyceride levels and the risk of incident cardiovascular disease, the semiquantitative techniques of meta-analysis were applied to 17 population-based prospective studies of triglyceride and cardiovascular disease. Sixteen of these studies represented 2,445 events among 46,413 Caucasian men followed for an average period of 8.4 years, and 5 studies re...

Secondary hyperlipidemia is a major cardiovascular risk factor in individuals with type 2 diabetes. Increased hepatic production of apolipoprotein B (apoB)-containing lipoproteins contributes to the elevated plasma levels, but the mechanism is poorly understood. Recent results have established that microsomal triglyceride transfer protein (MTP) is rate limiting for the assembly and secretion of...
