Interrelationships between human apolipoprotein A-I and apolipoproteins B-48 and B-100 kinetics using stable isotopes.
OBJECTIVE Our purpose was to determine the relationship between apolipoprotein (apo) A-I and apoB-48 and apoB-100 metabolism in moderately hypercholesterolemic humans. METHODS AND RESULTS The kinetics of apoA-I within high-density lipoprotein (HDL), apoB-48 and apoB-100 within triglyceride-rich lipoproteins, and apoB-100 within intermediate-density lipoprotein and low density-lipoprotein (LDL...
متن کاملHuman apolipoprotein (Apo) B-48 and ApoB-100 kinetics with stable isotopes.
The kinetics of apolipoprotein (apo) B-100 and apoB-48 within triglyceride-rich lipoproteins (TRLs) and of apoB-100 within IDL and LDL were examined with a primed-constant infusion of (5,5,5-(2)H(3)) leucine in the fed state (hourly feeding) in 19 subjects after consumption of an average American diet (36% fat). Lipoproteins were isolated by ultracentrifugation and apolipoproteins by SDS gels, ...
متن کاملApolipoprotein B 100 and 48
Apolipoprotein B is the main structural surface protein found on all beta-lipoproteins (Chylomicrons, VLDLs, IDLs and LDLs). There is a single molecule of apoB on each of those lipoproteins. It is the only apolipoprotein that is not transferablei.e. it is with the particle from its birth till its death. Beta-lipoproteins are the lipoproteins capable of trafficking cholesterol into the artery wa...
متن کاملMeasurement of human apolipoprotein B-48 and B-100 kinetics in triglyceride-rich lipoproteins using [5,5,5-2H3]leucine.
A primed-constant infusion of deuterated leucine was used in humans to determine the maximal level of enrichment at plateau of apolipoprotein (apo)B-48 and apoB-100 which are synthesized in the intestine and liver, respectively, and to compare the kinetics of these two proteins under identical conditions. Eight normal subjects (four post-menopausal females and four males) over the age of 40 wer...
متن کاملBoth apolipoproteins B-48 and B-100 are synthesized and secreted by the human intestine.
Apolipoprotein B (apoB), an apolipoprotein associated with very low density lipoproteins and the atherogenic low density lipoproteins (LDL), directs the metabolism of lipoprotein particles in plasma by interacting with the LDL receptor. Utilizing human intestinal biopsy organ cultures, we have studied the synthesis of intestinal apoB in man. Intestinal organ cultures from normal adults (n = 6) ...
