Interaction Between CYP4F2 rs2108622 and CPY4A11 rs9333025 Variants Is Significantly Correlated with Susceptibility to Ischemic Stroke and 20-Hydroxyeicosatetraenoic Acid Level.

ABSTRACT: AIMS:To investigate the association of four variants of two CYP ?-hydroxylase genes and 20-hydroxyeicosatetraenoic acid (HETE) levels with ischemic stroke (IS) and whether gene-gene interactions between these genes increase the risk of IS. METHODS:Three hundred ninety-six patients with IS and 378 controls were genotyped for rs2269231, rs9333025, rs2108622, and rs3093135. Gene-gene interactions were analyzed using generalized multifactor dimensionality reduction (GMDR) methods. The 20-HETE levels was measured in 218 IS patients and 126 controls. RESULTS:The frequency of the GG genotype of rs9333025 was significantly higher in IS patients than in controls (p?

Project description:Background 20-hydroxyeicosatetraenoic acids (20-HETE), products of arachidonic acid metabolism, possess a wide spectrum of important functions in the cardiovascular system and thereby may contribute to the development of many cardiovascular diseases (CVD). CYP2U1, CYP4A11 and CYP4F2 are important enzymes involved in the biosynthesis of 20-HETE and their genetic polymorphisms became attractive markers for testing of the genetic susceptibility to CVD. The present study investigated association between single nucleotide polymorphisms (SNP) of genes coding CYP2U1 (rs1493131), CYP4A11 (rs3890011, rs9332978, rs9333029), CYP4F2 (rs3093098, rs1558139), enzymes involved in the 20-HETE metabolism, and risk of various CVDs. Methods DNA samples from 3,940 unrelated Russian individuals comprising patients with essential hypertension (EH, N=1,410), CAD (N=561), ischemic stroke (IS, N=725), peripheral vascular disease (PVD, N=462) and 782 age- and sex-matched healthy subjects were genotyped for the polymorphisms using by the Mass-ARRAY 4 system. Results Polymorphism rs9332978 of the CYP4A11 gene showed a significant association with the risk of several CVD such as EH (OR =1.30, 95% CI: 1.04–1.62, P=0.02), CAD (OR =1.42, 95% CI: 1.14–1.78, P=0.002) and PVD (OR =1.53, 95% CI: 1.10–2.13, P=0.01). In addition, SNP rs3890011 of CYP4A11 was also associated with increased risk of CAD (OR =1.21, 95% CI: 1.02–1.24, P=0.03) and IS (OR =1.36, 95% CI: 1.14–1.64, P=0.001). The associations remained statistically significant after adjustment for sex, age and each CVD. The multifactor dimensionality reduction method identified epistatic gene-gene interactions (mainly between SNPs of CYP4A11 and CYP4F2) specifically associated with the risk of various CVDs. Conclusions The study findings demonstrate that pleiotropic effects of these genes may be responsible for the development of hypertension and atherosclerotic lesions of coronary, cerebral and peripheral arteries and the resulted disorders in the biosynthesis of 20-hydroxyicosatetraenoic acids may play an important role in pathogenesis of various CVDs.
