Symposium: Assembly and Physiology of Apolipoprotein B–Containing Lipoproteins: Not Just for Heart Disease Anymore! Assembly of Very Low Density Lipoprotein: A Two-Step Process of Apolipoprotein B Core Lipidation

چکیده
The liver plays a primary role in lipid metabolism. Important functions include the synthesis and incorporation of hydrophobic lipids, triacylglycerols and cholesteryl esters into the core of water-miscible particles called lipoproteins and the secretion of these particles into the circulation for transport to distant tissues. In this article, we present a brief overview of one aspect of the assembly process of very low density lipoproteins, namely, possible mechanisms for combining core lipids with apolipoprotein B. This is a complex process in which apolipoprotein B interacts with core lipids to form very low density lipoproteins by a two-step process that can be dissociated biochemically. J. Nutr. 129: 463S–466S, 1999.

The association between small dense low density lipoprotein,apolipoprotein B, apolipoprotein B/apolipoprotein A1 ratio and coronary artery stenosis
Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs are believed to be atherogenic since these particles are taken up more easily by arterial wall. They are readily oxidized and have reduced affinity for low density lipoprotein (LDL) receptor and increased affinity...

Although some previous studies have suggested that triglyceride, a major core lipid, plays a key role in the assembly and secretion of apolipoprotein B-containing lipoproteins from HepG2 cells, other reports have indicated the importance of cholesteryl ester, another core lipid. We attempted to better define the roles of triglyceride and cholesteryl ester in the assembly and secretion of apolip...
متن کاملAssembly of very low density lipoproteins in rat liver: a study of nascent particles recovered from the rough endoplasmic reticulum.
To investigate the assembly pathway for hepatic very low density lipoproteins (VLDL), nascent lipoproteins were recovered from a purified, intact rough endoplasmic reticulum (ER) fraction isolated from rat liver. Two fractions were recovered by ultracentrifugation. Particles isolated at d 1.006 g/ml were triglyceride-rich particles containing apolipoprotein (apo)B-100 or apoB-48, and apoE with ...
متن کاملApolipoprotein B-containing lipoprotein assembly in microsomal triglyceride transfer protein-deficient McA-RH7777 cells.
Microsomal triglyceride transfer protein (MTP) is required for the assembly and secretion of apolipoprotein (apo) B-containing lipoproteins. Previously, we demonstrated that the N-terminal 1,000 residues of apoB (apoB:1000) are necessary for the initiation of apoB-containing lipoprotein assembly in rat hepatoma McA-RH7777 cells and that these particles are phospholipid (PL) rich. To determine i...
