An apolipoprotein (apo) B-specific monoclonal antibody, MB19, detects a commonly occurring two-allele genetic polymorphism in human apoB (Young, S. G., S. J. Bertics, L. K. Curtiss, D. C. Casal, and J. L. Witztum. 1986. Proc. Natl. Acad. Sci. USA. 83: 1101-1105). Antibody MB19 binds to two different allotypes of apoB, MB19(1) and MB19(2), with high and low affinity, respectively. The epitope fo...

The metabolic syndrome is characterized by insulin resistance and abnormal apolipoprotein AI (apoAI) and apolipoprotein B-100 (apoB) metabolism that may collectively accelerate atherosclerosis. The effects of atorvastatin (40 mg/day) and micronised fenofibrate (200 mg/day) on the kinetics of apoAI and apoB were investigated in a controlled cross-over trial of 11 dyslipidemic men with the metabo...

We have studied the consequences of alterations to hepatic apoB mRNA editing on the biosynthesis and intracellular distribution of newly synthesized apoB variants together with their mass distribution in nascent Golgi very low density lipoproteins (VLDL). Radiolabeled liver membrane fractions were prepared from control or hypothyroid animals and separated by discontinuous sucrose gradient centr...

sumac (rhus coriaria l.) is used as an herbal remedy in traditional medicine. the aim of this study was to determine the effects of sumac (rhus coriaria l.) on serum glycemic status, apolipoprotein (apo) b, apoa-i and total antioxidant capacity (tac) in type 2 diabetic patients. this double blind randomized controlled clinical trial was conducted on 41 type 2 diabetic volunteers randomly assign...

We reported previously that a 116-kDa lipoprotein lipase (LPL)-binding protein from endothelial cells has sequence homology to the amino-terminal region of apolipoprotein (apo) B. We now tested whether endothelial cells synthesize apoB mRNA and protein. Primers were designed to the human apoB cDNA sequence and reverse transcription polymerase chain reaction was performed using total RNA isolate...

High concentration of apolipoprotein B (apoB) is a risk factor for coronary artery disease (CAD). The association of the APOB gene polymorphism c.12669G>A, p.Gln4154Lys with the risk of CAD varies considerably in different populations. The present study represents the first investigation regarding the role of this APOB gene polymorphism with CAD in the Indian Punjabi population. We have studied...

Obesity and type 2 diabetes are associated with insulin resistance (IR), increased circulating proinflammatory cytokines, and hypertriglyceridemia, the latter being caused by overproduction of hepatic very low density lipoprotein (VLDL). One cytokine strongly linked with development of hepatic IR is interleukin-6 (IL-6). Our objective was to evaluate IL-6 effects on hepatic apolipoprotein B (ap...

CONTEXT Familial hypobetalipoproteinemia (FHBL) is a codominant disorder of lipoprotein metabolism characterized by decreased plasma concentrations of low-density lipoprotein (LDL)-cholesterol and apolipoprotein B (apoB). OBJECTIVE The objective was to examine the effect of heterozygous APOB L343V FHBL on postprandial triglyceride-rich lipoprotein (TRL) and fasting lipoprotein metabolism. M...
