Influence of apolipoprotein-E gene on lipid profile, physical activity and body fat relationship

Abstract

Physical activity and body fat modify lipemia, and this effect seems to be influenced by apolipoprotein-E (APOE) gene polymorphism. Thus, the purpose of this article was to review main results of studies that have analyzed the relation of APOE gene with physical activity and body fat on triglycerides, total cholesterol and low (LDL) and high density lipoprotein (HDL) concentrations. The Scientific Electronic Library Online – SciELO, Web of Science and PubMed database were used to locate the articles. The keywords used in combination were: apoe genotype, apolipoprotein-E polymorphism, physical exercise, physical activity, aerobic exercise, body fat and obesity. Originals scientific investigations performed with humans were included, and excluded those ones which involved samples with diseases, except obesity and/or lipemic disorders. It was observed a trend, that ?2 allele carriers are the ones with the greater improvements on lipemia from physical exercise. In addition, the body fat impact on the elevation of triglycerides and LDL are stronger in carriers of the ?2 and ?4 allele, respectively. Considering the small number of originals scientific investigations and their divergent results, reliable inferences can not be made about the APOE gene polymorphism influences on physical activity and body fat effect on lipemia. Thus, further studies with others populations and more volunteers for allele, as well as others exercise modalities and intensities, are necessary.
