Cytotoxicity of lipid-free apolipoprotein B

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...

Lipid-dependent bidirectional traffic of apolipoprotein B in polarized enterocytes.

Enterocytes are highly polarized cells that transfer nutrients across the intestinal epithelium from the apical to the basolateral pole. Apolipoprotein B (apoB) is a secretory protein that plays a key role in the transepithelial transport of dietary fatty acids as triacylglycerol. The evaluation of the control of apoB traffic by lipids is therefore of particular interest. To get a dynamic insig...

Evidence of how rs7575840 influences apolipoprotein B-containing lipid particles.

OBJECTIVE Recent genome-wide association studies identified a variant rs7575840 in the apolipoprotein B (APOB) gene region as associated with low-density lipoprotein (LDL) cholesterol. However, the underlying functional mechanism of this variant, which resides 6.5 kb upstream of APOB, has remained unknown. Our objective was to investigate rs7575840 for association with refined apoB-containing l...

Apolipoprotein E Genotype Regulates Amyloid- Cytotoxicity

Cytoplasmic lipid droplets are sites of convergence of proteasomal and autophagic degradation of apolipoprotein B.

Lipid esters stored in cytoplasmic lipid droplets (CLDs) of hepatocytes are used to synthesize very low-density lipoproteins (VLDLs), into which apolipoprotein B (ApoB) is integrated cotranslationally. In the present study, by using Huh7 cells, derived from human hepatoma and competent for VLDL secretion, we found that ApoB is highly concentrated around CLDs to make "ApoB-crescents." ApoB-cresc...
