Abstract: Fish oil-derived long-chain omega-3 (n-3) polyunsaturated fatty acids (PUFAs), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), reduce the risk of cardiovascular disease by lowering plasma triglyceride (TG) and inflammation levels. However, a large inter-individual variability is observed, which could be explained by genetic factors. Genes involved in metabolic pathways of n-3 PUFA, including phospholipases A2 (PLA2) had changes in their expression in individuals who consumed 3 g/day of EPA and DHA for 6 weeks. Genotype by supplementation interaction effect on TG and C-reactive protein (CRP) levels were observed for PLA2 variations. These results suggest that variations in PLA2 genes may influence plasma TG and CRP levels during a supplementation with n-3 PUFA.
