Apolipoprotein A-IV is found in mesenteric lymph chylomicrons, very low density lipoprotein particles, high density lipoprotein particles, and in the lipoprotein-free fraction of plasma. Apolipoprotein A-IV is polymorphic in a variety of species including human, dog, and horse. Efforts to estimate the impact of apolipoprotein A-IV structural variation on quantitative lipid levels in humans have...

Lipoprotein(a) is an atherogenic lipoprotein whose function and plasma concentration reflect the structure and regulation of the apolipoprotein(a) gene. Apolipoprotein(a) is a close homologue of plasminogen, and their genes are tightly linked on chromosome 6. To further characterize these genes, we analyzed overlapping human genomic yeast artificial chromosome clones, which revealed a cluster o...

Two methods are compared for measuring the kinetic parameters of apolipoprotein A-I and A-I1 metabolism in human plasma. In the first, high density lipoprotein apoproteins were radioiodinated in situ in the lipoprotein particle (endogenous apoprotein labeling) while in the second, individually labeled apolipoprotein A-I or A-I1 was incorporated into the particle by in vitro incubation (exogenou...

1. Commercially available bovine serum albumin as Cohn fraction V was demonstrated to contain small amounts of apolipoprotein-CII. 2. This apolipoprotein activated lipoprotein lipase in the same way as apolipoprotein-CII purified from human very-low-density lipoproteins.

In the liver and the yolk sack of 6-12 week postfertilization human embryos, we have detected RNA transcripts from the following apolipoprotein genes: AI, AII, B, CII, CIII and E. The mRNA from the apolipoprotein CIII gene was relatively more abundant in the total RNA from the yolk sack than in that from the liver. The gut and adrenals contained transcripts of all these apolipoprotein genes apa...

Therapeutic proteins and peptides have potential to elicit immune responses resulting in anti-drug antibodies that can pose problems for both patient safety and product efficacy. During drug development immunogenicity is usually examined by risk-based approach along with specific strategies for developing "fit-for-purpose" bioanalytical approaches. Enzyme-linked immunosorbent assays and electro...

Lipoprotein glomerulopathy is a rare kidney disease in which lipoprotein thrombi are seen in the glomerular capillaries. Most of these patients are found in Japan and East Asian countries. The presenting symptoms include proteinuria, an abnormal plasma lipoprotein profile that resembles type III hyperlipoproteinaemia, and a marked increase in serum apolipoprotein E concentration. Previous studi...

OBJECTIVE To analyze the pattern of dyslipidaemias including apolipoprotein B in type 2 diabetes. METHODS A total of 120 diabetics were studied for their lipid profile including serum triglycerides, total cholesterol, HDL cholesterol and LDL cholesterol in fasting state, along with apolipoprotein B levels. RESULTS Raised apolipoprotein B was the most frequent lipid disorder in type 2 diabet...
