PURPOSE Inflammatory cells are known to be associated with the progression of atherosclerosis and plaque rupture. However, the relation to inflammatory cells and apolipoproteins on the progression of atherosclerosis is unknown. This study was aimed at examining the different expressions of inflammatory cells and evaluate the effect of apolipoprotein (APO) C1 and APO E during the progression of ...

The human apolipoprotein (apo) E gene is polymorphic, with three common alleles (epsilon 2, epsilon 3, epsilon 4) coding for three isoforms (E2, E3, E4). The isoforms differ from each other by a single amino acid substitution, and also differ in their binding affinity for the four apo E receptors. Apo E polymorphism is an important determinant of risk for the development of cardiovascular and A...

Apolipoprotein E (apo E) is important in plasma lipid metabolism and is a component of several plasma lipoprotein-lipid particles. Three major apo E isoforms are encoded by three common alleles at the APO E locus. The E2 allele is associated with lower and the E4 allele with higher total plasma cholesterol and LDL cholesterol levels compared with the E3 allele. Available data generally indicate...

The metabolism of apolipoproteins B-48 and B-100 (apo B-48 and B-100) in large triglyceride-rich lipoproteins was studied in three adults with familial dysbetalipoproteinemia (F. dys.) and compared to that of normolipidemic subjects. One Caucasian F. dys. subject was apparently homozygous for the common form of apo E-2, (Arg158----Cys), whereas the two Black subjects were homozygous for a diffe...

As genetically determined apolipoprotein E (apo E) phenotypes influence serum cholesterol concentration, we analysed whether serum triglyceride values are also affected by the apo E phenotypes in infants. Non-fasting serum triglyceride values were measured in 7- and 13-month-old participants in the STRIP project, a randomised, prospective trial aimed at reducing children's exposure to known ath...

The apolipoprotein (apo) B lipoproteins, intermediate-density lipoproteins (IDL) and low-density lipoproteins (LDL) that contain apo-CIII are associated with coronary heart disease in patients with diabetes mellitus. Apo-CIII is prominent in diabetic dyslipidemia. We studied whether these apo-B lipoprotein types containing apo-CIII in diabetics are reduced by 1 year of pravastatin treatment. We...

The impact of apo E polymorphism on interindividual variation in plasma lipid, lipoprotein concentrations, and LDL subfraction profiles was studied in 201 well-defined patients (88 men and 103 women) with familial combined hyperlipidemia (FCH). When corrected for the concomitant influences of age, gender and obesity, the allelic variation in the apo E gene was shown to explain a statistically s...

The impact of apo E phenotypes on applicability of relative cholesterol synthesis (lathosterol:cholesterol) and absorption (ratios of cholestanol, campesterol and sitosterol to cholesterol) during diets of various cholesterol and fat content is unclear. We examined and compared with each other both relative and absolute synthesis and absorption among twenty-nine men, of whom eight, nine and twe...

BACKGROUND Differences in serum lipid distribution and mortality from ischaemic heart disease have repeatedly been reported between Belgian northerners and southerners. We investigated whether serum lipoprotein(a) (Lp(a)) and apolipoprotein (apo) E polymorphism were involved. METHODS Fasting serum lipids, apo A-I and B, and Lp(a) levels were examined in randomly selected, 20-39 year old Belgi...

We have generated transgenic mice over-expressing human apolipoprotein CI (apo CI) using the native gene joined to the downstream 154-bp liver-specific enhancer that we defined for apo E. Human apo CI (HuCI)-transgenic mice showed elevation of plasma triglycerides (mg/dl) compared to controls in both the fasted (211 +/- 81 vs 123 +/- 52, P = 0.0001) and fed (265 +/- 105 vs 146 +/- 68, P < 0.000...
