Lipoprotein assembly. Apolipoprotein B size determines lipoprotein core circumference.

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...

Cys4057 of apolipoprotein(a) is essential for lipoprotein(a) assembly.

Lipoprotein(a) contains one copy each of apolipoprotein B-100 and apolipoprotein(a). It has been hypothesized that a disulfide bond might exist between Cys4057 of apolipoprotein(a) and Cys3734 in apolipoprotein B-100. To investigate the role of Cys4057 for lipoprotein(a) assembly, wild-type and in vitro mutagenized apolipoprotein(a) cDNA plasmids were expressed in the human hepatocarcinoma line...

Apolipoprotein 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...
