The Effect of E-EPA on Circulating LDL and Plasma Lipid Metabolism

2019-11-11 17:50:32 | BioPortfolio


40-70 healthy volunteers of ages 18 to 65 participate in a E-EPA-diet where 3,9 grams of E-EPA is added to their normal diet and lifestyles for a month. Blood samples will be collected before the study and at weeks 1 and 4 and also, two weeks after finishing the diet. Main study focuses are LDL aggregation susceptibility, lipid composition and proteoglycan binding affinity. In addition, important plasma lipid metabolism enzymes and lipid mediated resolvins are measured as well as several baseline characteristics.


Four grams of daily E-EPA was found to significantly decrease atherosclerotic cardiovascular diseases in the REDUCE-IT study. In the upcoming study the effect of E-EPA to low-density lipoprotein (LDL) aggregation susceptibility is measured using dynamic light scattering technique to continuously measure particles size while inducing aggregation. LDL Lipid composition is analyzed using electrospray mass spectrometer optimized for lipid measurements. Previously is reported that the aggregation susceptibility is affected by the lipid composition which is modifiable (Ruuth et. al. Eur.H.Journal 2018). Common disease factors such as total cholesterol, LDL, HDL, triglyserides, ApoB-100, ApoA-I, Lp(a) and different modified LDL levels are measured. Also, activities of lipid metabolism enzymes like PON-1, LCAT, CETP, PLTP and lipid mediated resolvins are looked into. Objective is to identify changes and possible pathways that are altered by the increase of E-EPA and to use the data to possibly explain the health benefits of EPA.

Medical and Biotech [MESH] Definitions

Important polyunsaturated fatty acid found in fish oils. It serves as the precursor for the prostaglandin-3 and thromboxane-3 families. A diet rich in eicosapentaenoic acid lowers serum lipid concentration, reduces incidence of cardiovascular disorders, prevents platelet aggregation, and inhibits arachidonic acid conversion into the thromboxane-2 and prostaglandin-2 families.

Trihydroxy derivatives of eicosanoic acids. They are primarily derived from arachidonic acid, however eicosapentaenoic acid derivatives also exist. Many of them are naturally occurring mediators of immune regulation.

A gas that condenses under slight pressure. Because of its low boiling point ethyl chloride sprayed on skin produces an intense cold by evaporation. Cold blocks nerve conduction. Ethyl chloride has been used in surgery but is primarily used to relieve local pain in sports medicine.

Organic compounds having ethyl groups bound to an oxygen atom

3-Ethyl-2-(5-(3-ethyl-2-benzothiazolinylidene)-1,3- pentadienyl)benzothiazolium. A benzothiazole that was formerly used as an antinematodal agent and is currently used as a fluorescent dye.
