OBJECTIVE To determine whether apo E phenotype influences changes in lipid profiles induced by growth hormone replacement in growth hormone (GH)-deficient adults. DESIGNS Patients were treated for 6 months with recombinant human GH (hGH), given in a dose of 0.125 U/kg per week for 4 weeks followed by 0.25 U/kg per week thereafter. The effects on serum lipids and the influence of apo E phenoty...

Abstract Introduction The clinical consequences of atherosclerosis and post-procedure neointimal hyperplasia (NIH) represent a significant proportion the vascular surgeon's workload. Lectin-like oxidized low density lipoprotein receptor-1 (LOX-1) is class E scavenger receptor expressed in endothelial cells implicated NIH. This study aims to demonstrate therapeutic potential LOX-1 targeting usin...

The effect of 25-hydroxycholesterol (25-OH-cholesterol) and chenodeoxycholic (CDC) acid on apoprotein secretion, low-density lipoprotein receptor activity, and [3H]triacylglycerol secretion in Hep G2 cells was studied. Both 25-OH-cholesterol and CDC acid increased the secretion of apolipoprotein (apo) E by Hep G2 cells. The secretion of apo A-I was slightly lowered (less than 10% disease). The ...

A new immunoaffinity technique for purifying anti-apolipoprotein CIII antibodies has been developed by isolating bands of apo CIII2 from isoelectric focusing (IEF) gel. Total apo C was obtained from delipidated very-low-density lipoprotein by chromatography on Sephacryl S 200. Apo CIII2 was separated from the apo CII band by IEF on polyacrylamide gel with use of pH 4-6 ampholytes. After sonicat...

The aim of the current study was to determine whether oxidized cholesterol in the diet accelerates atherosclerosis in low density lipoprotein receptor- (LDLR) and apolipoprotein E- (apo E) deficient mice. Mice were fed either a control diet or a diet containing oxidized cholesterol. For LDLR-deficient mice, the control diet consisted of regular mouse chow to which 1.0% cholesterol was added. Th...

With the aim of establishing whether a genetically reduced capability of producing apolipoprotein E (apo E) can affect atherogenesis, we have compared the consequences of dietary stress on normal mice and on mice heterozygous or homozygous for a disrupted apo E gene. A dramatically accelerated development of lesions occurred in the vasculature of the homozygous mutants as a result of feeding an...

BACKGROUND & OBJECTIVES Myocardial infarction and stroke are leading causes of death worldwide. Primarily, arteriosclerosis is responsible for these events. There is a strong family history suggesting a genetic cause. Apolipoprotein E (apo E) plays an important role in lipid metabolism. Apo E is polymorphic with three isoforms, ApoE2, ApoE3 and ApoE4; which translate into three alleles of the g...

Apolipoprotein E (apo E) plays an important role in lipid metabolism and its polymorphism may be a risk determinant of coronary heart disease (CHD). Since evidence suggested a gender-specific effect of apo E polymorphism, we studied the influence of gender-specific interaction of the polymorphism on CHD. From a total of 463 Greek Caucasians (314 men and 149 postmenopausal women) with angiograph...
