Impaired chylomicron remnant clearance in familial combined hyperlipidemia.
Postprandial chylomicron remnant clearance was studied in six patients with familial combined hyperlipidemia (FCH) and seven control subjects by using an oral retinyl palmitate (RP) fat-loading test. The chylomicron remnant clearance (Sf < 1,000 fraction), expressed as the area under the RP curve (AUC-RP), was delayed in FCH subjects (65.05 +/- 12.84 hours x [mg/L]) compared with control subjec...
متن کاملChylomicron-remnant clearance in homozygote and heterozygote
Lymph chylomicrons radiolabelled in triacylglycerol and cholesteryl ester were injected into control and Watanabe heritable-hyperlipidaemic (WHHL) rabbits. Clearance of chylomicrons was slower in heterozygote and homozygote WHHL rabbits. Slower remnant clearance in WHHL rabbits was confirmed by monitoring the clearance from plasma of preformed chylomicron remnants. Use of chylomicron-like lipid...
متن کاملChylomicron-chylomicron remnant clearance by liver and bone marrow in rabbits. Factors that modify tissue-specific uptake.
The metabolism of [14C]cholesterol- and [3H]retinol-labeled chylomicrons obtained from canine thoracic duct or rabbit mesenteric lymph was investigated in normal fasted rabbits. Typically, 70-80% of the chylomicrons injected into the rabbits were cleared from the plasma in 20 min, and their uptake was accounted for principally by the liver and the bone marrow. Surprisingly, the bone marrow was ...
متن کاملKinetics of chylomicron remnant clearance in normal and in hyperlipoproteinemic subjects.
The kinetics of chylomicron metabolism have been studied by measuring retinyl palmitate in chylomicrons and their remnants for 10-12 hr following oral administration of vitamin A and Lipomul in three groups of adult male subjects: A) normal plasma triglyceride levels (n = 7); B) endogenous hypertriglyceridemia (n = 12); C) apolipoprotein E (apoE) phenotype E2/2, with Type 3 hyperlipoproteinemia...
متن کاملAn apolipoprotein(a) peptide delays chylomicron remnant clearance and increases plasma remnant lipoproteins and atherosclerosis in vivo.
OBJECTIVE Humans with high expression of apolipoprotein(a) [apo(a)] and high plasma levels of lipoprotein(a) [Lp(a)] are at increased risk for atherosclerosis, but the mechanism is not known. We have previously shown that the KIV(5-8) domain of apo(a) has unique cell-surface binding properties, and naturally occurring fragments of apo(a) encompassing this domain are thought to be atherogenic in...
