OBJECTIVE This study was designed to address the effects of increased lipoprotein lipase (LPL) activity on atherosclerosis in the setting of LDL receptor deficiency. METHODS We generated transgenic (Tg) Watanabe heritable hyperlipidemic (WHHL) rabbits overexpressing human LPL and compared their plasma lipids and aortic atherosclerosis with non-Tg WHHL rabbits. RESULTS Increased expression o...

The mutant tg/tg mice, which do not express mi transcription factor (MITF), lack mast cells in most tissues. Since MITF is expressed in both mast cells and tissues where mast cells develop, there is a possibility that the tg/tg mice may show abnormalities in both mast cell precursors and tissue environments. We examined this possibility by bone marrow and skin transplantation. When bone marrow ...

Cholesteryl ester transfer protein (CETP) mediates the transfer of HDL cholesteryl esters for triglyceride (TG) in VLDL/LDL. CETP inhibition, with anacetrapib, increases HDL-cholesterol, reduces LDL-cholesterol, and lowers TG levels. This study describes the mechanisms responsible for TG lowering by examining the kinetics of VLDL-TG, apoC-II, apoC-III, and apoE. Mildly hypercholesterolemic subj...

OBJECTIVE The study analyses i) the effect of overweight, waist circumference and dietary habits on postprandial (pp) triglyceride (TG) response and compares ii) pp TG response with fasting TG levels and iii) pp TG peak values with TG-AUC (area under curve) with respect to cardiometabolic risk assessment. METHODS In 100 men (44-68 years) body composition (air-displacement plethysmography), di...

A detailed comparison of the structures of plasma very low density lipoprotein (VLDL) and liver triacylglycerols (TG) (Yang et al. 1995. J. Lipid Res. 36: 125-136) has demonstrated that a minimum of 60% of the secreted TG could have been derived from partial lipolysis and reesterification of stored TG and a maximum of 40% could have been derived from direct secretion of newly made TG. To invest...

Tracheal glands (TG) may play a specific role in the pathogenesis of cystic fibrosis (CF), a disease due to mutations in the cftr gene and characterized by airway inflammation and Pseudomonas aeruginosa infection. We compared the gene expression of wild-type TG cells and TG cells with the cftr DeltaF508 mutation (CF-TG cells) using microarrays covering the whole human genome. In the absence of ...

Triglyceride (TG) or more accurately triacylglycerol is simply a compound of three acyl groups (fatty acids) attached to a glycerol molecule. They are easily measured in the laboratory and reported as serum TG level: it actually refers to all of the TG that are being trafficked within all of the lipoproteins that exist in a deciliter of plasma. A physiologic fasting TG concentration is on avera...
