This study was designed to gain insight into the role of microsomal triglyceride transfer protein (MTP) in the association of apolipoprotein (apo) B with lipid during intestinal lipoprotein assembly. The MTP-inhibiting compound BMS-200150 (Jamil et al. 1996. Proc. Natl. Acad. Sci. USA 93: 11991-11995) was used to inhibit the lipid transfer activity of MTP in Caco-2 cells. MTP inhibition reduced...

BACKGROUND There is considerable evidence that remnants of triglyceride-rich lipoproteins may be particularly atherogenic. METHODS AND RESULTS Levels of lipoprotein lipids and of apolipoprotein B in low-density lipoproteins were measured in 335 men and women enrolled in a study in which quantitative coronary angiography was carried out at 2-year intervals. Clinical events related to coronary ...

The net synthesis of low density plasma lipoproteins has been shown in the perfused rat liver and in rat liver slices in work reported from this laboratory (2). Haft, Roheim, White, and Eder (3) demonstrated amino acid incorporation into low and high density plasma lipoproteins in the perfused liver, and Radding and Steinberg (4) reported similar observations in rat liver slices. The present ex...

Anchoring of proteins to membranes by lipid modification is a universal strategy of both prokaryotic and eukaryotic cells. The spirochaetes represent a distinct bacterial phylum that have utilized the lipoprotein design extensively as evidenced by genome-sequencing studies revealing a large number of different paralogous families of lipoprotein genes, encoding 22 potential lipoproteins in Trepo...

Among the apoA-I-containing lipoproteins isolated by selected-affinity immunosorption from human serum and plasma, we have identified a subpopulation which, unlike the bulk of high density lipoproteins, has pre-beta electrophoretic mobility. This pre-beta subpopulation can be observed directly in fresh plasma by immunoelectrophoresis. It contains phospholipid and free and esterified cholesterol...
