Background and Aims : Angiopoietin-like protein 3 (ANGPTL3) inhibition reduces LDL-cholesterol (LDL-C), triglycerides (TG) HDL-C in patients with hyperlipidemia. Post-prandially, ANGPTL8 forms a complex ANGPTL3; the ANGPTL3/8 inhibits lipoprotein lipase 100-fold more potently circulates at much lower levels than ANGPTL3 alone. This phase 1 study assessed safety pharmacology of single ascending ...

BACKGROUND Lipopolysaccharide (LPS), which is released from gram-negative bacteria on multiplication or lysis, aggravates atherosclerosis in humans and rodents by inducing inflammation via toll-like receptors. Because apolipoprotein C-I (apoCI) enhances the LPS-induced inflammatory response in macrophages in vitro and in mice, we investigated the effect of endogenous apoCI expression on LPS-ind...

The effect of human C-I, C-11, and C-111-2 apolipoproteins on the metabolism of triglyceride in triglyceride emulsions was studied in the in vitro perfused rat liver and the nonreplicating hepatocyte monolayer culture. All three human apolipoproteins delayed hepatic uptake of the triglyceride emulsion, both when the emulsion was supplemented with human apolipoprotein E and without this apolipop...

We examined the relationship between maternal smoking during pregnancy and serum lipid, lipoprotein and apolipoprotein levels in newborns. Serum concentrations of total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A-1, apolipoprotein B and lipoprotein (a) were assessed in blood samples from 38 mothers who were smokers and t...

We examined the cholesterol/protein ratio and the apoprotein composition of serum lipoproteins in a randomly selected population of maturity-onset diabetics and in a group of nondiabetics of similar age. We found no differences in cholesterol distribution between the groups as a whole, but diabetics with above-normal low-density lipoproteins (LDL) had decreased concentrations of high-density li...

Peptides corresponding to the proposed lipid-binding domains of human apolipoprotein C-I, residues 7-24 (ALDKLKEFGNTLEDKARE) and 35-53 (SAKMREWFSETFQKVKEKL), were studied by CD and two-dimensional 1H NMR spectroscopy. Sodium dodecyl sulfate (SDS) was used to model the lipoprotein environment. Analysis of the CD data shows that both peptides lack well-defined structure in aqueous solution but ad...

ApoC-III and apoE are important determinants of intravascular lipolysis and clearance of triglyceride-rich chylomicrons and VLDL from the blood plasma. Interactions of these two apolipoproteins were studied by adding purified human apoC-III to human plasma at levels observed in hypertriglyceridemic subjects and incubating under specific conditions (2 h, 37 degrees C). As plasma concentrations o...

OBJECTIVE To assess the risk factors, lipid and apolipoprotein profile, hemostasis variables, and polymorphisms of the apolipoprotein AI-CIII gene in early coronary artery disease (CAD). METHODS Case-control study with 112 patients in each group controlled by sex and age. After clinical evaluation and nutritional instruction, blood samples were collected for biochemical assays and genetic stu...
