Title: Paraoxonase 1 and atherosclerosis: is the gene or the protein more important? Mackness MI, Mackness B Ref: Free Radic Biol Med, 37:1317, 2004 : PubMed
The oxidation of low-density lipoprotein (LDL) is centrally involved in the initiation and progression of atherosclerosis. High-density lipoprotein (HDL) paraoxonase 1 (PON1) retards the oxidation of LDL and is a major antiatherosclerotic component of HDL. The PON1 gene contains a number of functional polymorphisms in both the coding and the promoter regions, which affect either the level or the substrate specificity of PON1. Genetic case-control and prospective studies conducted to date have produced confusing results. Meta-analysis of these studies indicates no simple relationship between the PON1 polymorphisms and the presence of coronary heart disease (CHD). However, at the present moment in time, it seems that PON1 status, i.e., activity and/or concentration, is more closely related to CHD, and indeed, PON1 has shown to be an independent risk factor for CHD in a prospective study, compared to the genetic polymorphisms. PON1 levels can also be modulated by environmental\lifestyle and possibly pharmaceutical factors. Larger, better designed, preferably prospective studies are needed to determine further the association of PON1 genetic polymorphisms and status with CHD.
