Abstract

| Much evidence has accumulated to suggest a role for the oxidation of low-density-lipoprotein (LDL) and very low-density-lipoprotein (VLDL) in the pathogenesis of atherosclerosis. The susceptibility of lipoprotein to copper-catalyzed oxidation is often used to evaluate its oxidizability. A method was developed which isolates the non-high-density lipoprotein (non-HDL) fraction and removes EDTA by a dextran-magnesium precipitation method. The oxidizability of this fraction is evaluated by monitoring the fluorescence and measuring thiobarbituric acid reactive substances (TBARS) at different intervals of incubation. Those parameters reflect apolipoprotein B (apo B) modification and lipid degradation during LDL and VLDL oxidation. Our assay is sensitive enough to study factors which can influence the oxidizability of LDL and VLDL. The method is simple, rapid and can be easily conducted in a routine laboratory. |
