Cloning and expression of apolipoprotein B, the major protein of low and very low density lipoproteins.
We report the cloning of cDNAs for rat liver apolipoprotein B (apo B) and the use of the cloned sequences to examine apo B expression at the level of mRNA in rat tissues. Fifteen putative apo B clones were identified by antibody screening of a rat liver cDNA library in the lambda gt11 expression vector. The identity of the clones was confirmed by immunological studies of the fusion protein prod...
متن کاملMetabolism of apolipoprotein B in large triglyceride-rich very low density lipoproteins of normal and hypertriglyceridemic subjects.
The metabolic fate of very low density lipoprotein can be examined by following the transit of its apolipoprotein B moiety through the delipidation cascade, which leads to low density lipoprotein. In this study we have used cumulative flotation ultracentrifugation to follow the metabolism of various lipoprotein subclasses that participate in this process in normal, hypertriglyceridemic (Type IV...
متن کاملEnzyme immunoassay for human apolipoprotein B, the major protein moiety in low-density- and very-low-density lipoproteins.
We used enzyme immunoassay to measure apolipoprotein B concentration in human plasma. Pure lipoprotein B was isolated from serum samples of fasting normolipidemic subjects by sequential preparative ultracentrifugation and coated to a polystyrene tube surface by adsorption. Human serum samples and rabbit antiserum to human apolipoprotein B were incubated with the solid-phase lipoprotein B. Solub...
متن کاملThe 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...
متن کاملStructure of apolipoprotein B-100 of human low density lipoproteins.
We have analyzed low density lipoproteins (LDL) apolipoprotein (apop) B structure by direct sequence analysis of LDL apo B-100 tryptic peptides. Native LDL were digested with trypsin, and the products were fractionated on a Sephadex G-50 column. The partially digested apo B-100 still associated with lipids was recovered in the void volume (designated trypsin-nonreleasable, TN, peptides). The re...
