Familial defective apolipoprotein B-100: a mutation of apolipoprotein B that causes hypercholesterolemia.

Journal of Lipid Research, 1990
Familial defective apolipoprotein B-100 is a genetic disorder of apolipoprotein B-100 that causes moderate to severe hypercholesterolemia. A single amino acid mutation in apolipoprotein B diminishes the ability of low density lipoproteins to bind to the ...

Oxidative events cause degradation of apoB-100 but not of apo[a] and facilitate enzymatic cleavage of both proteins

Journal of Lipid Research, 2001
Lipoprotein [a] (Lp[a]) contains equimolar amounts of apoB-100 and apolipoprotein [a] (apo[a]). Both proteins are amenable to degradation in vivo by mechanisms yet to be clearly defined.

Ferritin heavy chain Is the host factor responsible for HCV-Induced inhibition of apoB-100 production and is required for efficient viral infection [PDF]

, 2012
Hepatic fat export occurs by apolipoprotein B-100-containing lipoprotein production, whereas impaired production leads to liver steatosis. Hepatitis C virus (HCV) infection is associated to dysregulation of apoB-100 secretion and steatosis; however, the ...

Apolipoprotein[a] secretion from hepatoma cells is regulated in a size-dependent manner by alterations in disulfide bond formation

Journal of Lipid Research, 2003
Apolipoprotein[a] (apo[a]) is a large disulfide linked glycoprotein synthesized by hepatocytes. We have examined the role of disulfide bond formation in the processing of apo[a] using human and rat hepatoma cells expressing apo[a] isoforms containing ...

Human Placenta Secretes Apolipoprotein B-100-containing Lipoproteins [PDF]

Journal of Biological Chemistry, 2004
Supply of lipids from the mother is essential for fetal growth and development. In mice, disruption of yolk sac cell secretion of apolipoprotein (apo) B-containing lipoproteins results in embryonic lethality. In humans, the yolk sac is vestigial. Nutritional functions are instead established very early during pregnancy in the placenta.

PPARα deficiency increases secretion and serum levels of apolipoprotein B-containing lipoproteins

Journal of Lipid Research, 2001
This study investigates the importance of peroxisome proliferator activated receptor α (PPARα) for serum apolipoprotein B (apoB) levels and hepatic secretion of apoB-containing lipoproteins.

Degradation of human apolipoprotein B‐100 by apolipoprotein(a)

FEBS Letters, 1993
Human plasma low density lipoproteine (LDL) contain a very high molecular weight protein termed apoB‐100 (M r = 550,000). In many samples of LDL, minor components designated as apoB‐74 (M r = 407,000) and apoB‐26 (M r = 145,000) are present. It has been shown that they can arise as a result of proteolytic degradation of apoB‐100.

The secondary structure of apolipoprotein A-I on 9.6-nm reconstituted high-density lipoprotein determined by EPR spectroscopy. [PDF]

, 2013
Apolipoprotein A-I (ApoA-I) is the major protein component of high-density lipoprotein (HDL), and is critical for maintenance of cholesterol homeostasis.

Key intestinal genes involved in lipoprotein metabolism are downregulated in dyslipidemic men with insulin resistance

Journal of Lipid Research, 2014
Insulin resistance (IR) is associated with elevated plasma levels of triglyceride-rich lipoproteins (TRLs) of intestinal origin. However, the mechanisms underlying the overaccumulation of apolipoprotein (apo)B-48-containing TRLs in individuals with IR ...

Production of a soluble and functional recombinant apolipoproteinD in the Pichia pastoris expression system [PDF]

, 2016
ApolipoproteinD (ApoD) is a human glycoprotein from the lipocalin family. ApoD contains a conserved central motif of an 8-stranded antiparallel β-sheet, which forms a beta-barrel that can be used for transport and storage of diverse hydrophobic ligands ...
