100 patients with beta-thalassemia trait, comprised of 55 men and 45 women, participated in a study to measure serum lipoproteins. the results were compared with the data obtained from 100 control subjects of the same age and sex. a significantly lower level of mean serum total cholesterol and ldl cholesterol, and a much higher level of hdl cholesterol were obtained in beta-thalassemia trait as...
Fast lipoprotein chromatography (FLPC) is a novel method for quantifying lipoproteins. Plasma proteins are separated by fast-flow gel filtration. Lipoproteins are detected by post-column derivatization with an enzymatic cholesterol reagent. FLPC resolves very-low-, low-, and high-density lipoproteins (VLDL, LDL, and HDL, respectively) and completely separates apolipoprotein Al- and apolipoprote...
Lipoproteins of the Sf 12-100 class, representing only about 10 to 15 per cant of the serum cholesterol, are strongly associated with atherosclerosis. The major independent contributions to this association are from the Sf 12-20 lipoproteins and the Sf 35-100 lipoproteins. The Sf 20-35 lipoproteins are primarily associated by virtue of their intercorrelation with the other classes. Obesity is m...
We examined the migratory properties of the mouse serum protein responsible for specific neutralization of the endogenous mouse xenotropic type C virus and demonstrated that this neutralizing factor can be transferred from mouse lipoproteins to human and to nonreactive mouse lipoproteins. After acceptance of this activity by these lipoproteins, it could be back-transferred to human and to mouse...
The cholesteryl esters of very low density lipoproteins become labeled when human plasma is incubated with cholesterol-(14)C. The relative order of magnitude of the specific activity of the cholesteryl esters of the major lipoprotein fractions is: high density lipoproteins >> very low density lipoproteins > low density lipoproteins. This pattern of labeling is similar to that found by others in...
A method to measure apolipoprotein B radioactivity in whole blood plasma is described that is suitable for routine use in kinetic experiments in vivo. Radiolabeled apolipoprotein B is precipitated from plasma diluted 15- to 30-fold in the presence of carrier low density lipoproteins by 50% isopropanol. The amount of radioiodine in apoB is estimated from the difference between total radioiodine ...
It has been previously shown that transfection activity of cationic liposome/DNA lipoplexes delivered systemically is drastically inhibited by lipoproteins (Tandia, B. M., Vandenbranden, M., Wattiez, R., Lakhdar, Z., Ruysschaert, J. M., and Elouahabi, A. (2003) Mol Ther. 8, 264-273). In this work, we have compared the binding/uptake and transfection activities of DOTAP (N-[1-(2,3-dioleoyloxy)pr...
Plasma lipoproteins of d<1.006 g/ml, d 1.006-1.019 g/ml, and d 1.019-1.063 g/ml from patients with familial lecithin:cholesterol acyltransferase deficiency yielded abnormal subfractions upon being separately filtered through 2% agarose gel. A subfraction that emerged with the void volume and contained unusually large amounts of unesterified cholesterol and phosphatidylcholine was present in eac...
Mice lacking hepatic lipase have been reported to express mild hyperlipidemia characterized by increased concentrations of large high density lipoproteins, but normal concentrations of lipoproteins containing apolipoprotein B. Whereas hepatic lipase has been implicated in the clearance and processing of chylomicron remnants in rats, no such defect was found in these mice. We have further charac...
