OBJECTIVE To evaluate the effects of hyperglycemia due to partial insulin deprivation on myocardial triglyceride (TG) content and myocardial function in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS Myocardial and hepatic TG content and left ventricular (LV) function were measured by magnetic resonance (MR) spectroscopy and MR imaging during optimal glucoregulation and after 24 h...

When weanling rats were given 70% casein diet deficient in pyridoxine, they showed marked accumulation of liver lipid consisting mainly of triglyceride (TG) and cholesterol ester (CE). The serum concentrations of phospholipid (PL) and cholesterol (CH) in pyridoxine deficient rats were significantly lower than those in pair-fed controls, but their serum levels of TG and free fatty acid (FFA) wer...

An increase in hepatic triglyceride (TG) contents usually results in non-alcoholic fatty liver disease (NAFLD) and related metabolic diseases. However, the mechanisms underlying perturbations of hepatic TG homeostasis remain largely unknown. Here, we showed that MicroRNA-124 was up-regulated in the livers of C57BL/6 mice fed a short-term high-fat-diet (HFD). Adenoviral overexpression of miR-124...

Hypertriglyceridemia is considered a cardiovascular risk factor in diabetic and nondiabetic subjects. In this study, we aimed to determine potential regulators of very low density lipoprotein-triglyceride (TG) production. VLDL-TG kinetics were measured in 13 men and 12 women [body mass index [mean (range)]: 24.8 (20.2-35.6) kg/m(2)]. VLDL-TG production was assessed from the plasma decay of a bo...

Plasma triglyceride (TG)-rich lipoproteins are related to high density lipoprotein (HDL)-cholesterol and risk of coronary artery disease (CAD). Two major hypotheses on the role of HDL in the development of CAD have been proposed: a 'causalist' view assigns a protective effect against atherosclerosis to HDL and a 'non-causalist' view states that HDL do not interfere directly with development of ...

Triglyceride (TG) secretion from liver and its storage in abdominal cavity of the broiler affects the net meat yield. So agents that affect the hepatic TG secretion may be important for poultry breeders. At present study, we have shown short term effects of insulin on the chicken liver TG secretion at the first, third, fifth and seventh weeks of breeding. For this purpose, 10 , 10 and 10 M insu...

Efficient catabolism of cellular triacylglycerol (TG) stores requires the TG hydrolytic activity of adipose triglyceride lipase (ATGL). The presence of comparative gene identification-58 (CGI-58) strongly increased ATGL-mediated TG catabolism in cell culture experiments. Mutations in the genes coding for ATGL or CGI-58 in humans cause neutral lipid storage disease characterized by TG accumulati...

Apoprotein (apo) C-III plays an important role in the development of hypertriglyceridemia by inhibiting triglyceride (TG) removal. However, the effect of apo C-III on TG production remains unclear. We measured TG secretion rate (TGSR) in apo C-III gene-disrupted (apo C-III-null) mice to investigate the influence of this protein on TG turnover. TGSR measured by the Triton WR-1339 method was incr...

Studies on plasma triglycerides (TG) were performed in 10 nonobese and 16 obese patients with hypothyroidism and in 13 with hyperthyroidism. Nonobese, hypothyroid patients generally had normal levels of TG, but obese patients often had hypertriglyceridemia. In most hypothyroid patients 1-thyroxine treatment lowered plasma TG, and most hyperthyroid patients had low TG. One mechanism whereby thyr...

Apolipoprotein A-V (apoA-V) is an important regulator of plasma levels of triglyceride (TG) in mice. In humans, APOA5 genetic variation is associated with TG in several populations. In this study, we determined the effects of the p.185Gly>Cys (c.553G>T; rs2075291) polymorphism on plasma TG levels in subjects of Chinese ancestry living in the United States and in a group of non-Chinese Asian anc...
