Decreased production rates of VLDL triglycerides and ApoB-100 in subjects heterozygous for familial hypobetalipoproteinemia.
Familial hypobetalipoproteinemia (FHBL) is an autosomal codominant disorder characterized by low levels of apolipoprotein (apo) B and low-density lipoprotein (LDL) cholesterol. Decreased production rates of apoB have been demonstrated in vivo in FHBL heterozygotes. In the present study, we wished to investigate whether the transport of triglycerides was similarly affected in these subjects. The...
متن کاملEffect of weight loss on VLDL-triglyceride and apoB-100 kinetics in women with abdominal obesity.
The effects of obesity and weight loss on lipoprotein kinetics were evaluated in six lean women [body mass index (BMI): 21 +/- 1 kg/m(2)] and seven women with abdominal obesity (BMI: 36 +/- 1 kg/m(2)). Stable isotope tracer techniques, in conjunction with compartmental modeling, were used to determine VLDL-triglyceride (TG) and apolipoprotein B-100 (apoB-100) secretion rates in lean women and i...
متن کاملEffects of ApoE genotype on ApoB-48 and ApoB-100 kinetics with stable isotopes in humans.
Subjects with the apolipoprotein (apo) E4 allele have been shown to have higher low density lipoprotein (LDL) cholesterol and apoB levels than do subjects with the other alleles. To elucidate the metabolic mechanisms responsible for this finding, we examined the kinetics of apoB-48 within triglyceride-rich lipoproteins (TRLs) and of apoB-100 within very low density lipoprotein (VLDL), intermedi...
متن کاملIncreased production of VLDL apoB-100 in subjects with familial hypercholesterolemia carrying the same null LDL receptor gene mutation.
Early radiokinetic studies revealed that the classical metabolic defect in patients with familial hypercholesterolemia (FH) is hypocatabolism of LDL due to decreased LDL receptor activity. However, recent studies have suggested that hepatic oversecretion of apolipoprotein B-100 (apoB-100)-containing lipoproteins could also contribute to the markedly elevated plasma concentrations of LDL-cholest...
متن کاملآدیپوسیتوکینها و متابولیسم VLDL: اثرات تنظیمی آدیپونکتین، مقاومت به انسولین و اجزای بافت چربی بر کینتیک apoB-100 VLDL
Background: Obesity is an escalating public health problem. It is a major risk factor for atherosclerosis, hypertension, and type 2 diabetes. Since circulating levels of the adipocytokins are associated with obesity and dyslipidemia, we investigated the relationship of plasma adipocytokine concentrations with VLDL apolipoprotein B (apoB)-100 kinetics in men. Methods: Plasma adiponectin, lepti...
