Analysis of the Role of Carriership of Polymorphic Genotypes of ESR1, eNOS, and APOE4 Genes in the Development of Arterial Hypertension in Men
We studied the role of the carrier status for polymorphic loci of genes encoding estrogen receptors (ESR1), endothelial NO synthase (eNOS), and apolipoprotein E (APOE4) and products of their expression nitrogen oxide (NO) and apolipoprotein (ApoE) in the development of arterial hypertension in men. Conventionally healthy volunteers and 149 men with clinical manifestations of stage I-II arterial hypertension were examined. In men with arterial hypertension, the frequency of minor allele A of ESR1 gene was higher (27.5 vs. 9.5% in the reference group; χ2=4.43, p=0.04). The level of NO in the peripheral blood was also higher in the main group (χ2=3.93, p=0.047). The increase in NO concentration did not depend on the presence of polymorphic genotypes (GG and GT) of eNOS gene, but the decrease in ApoE level in blood serum was associated with TC genotype of APOE4 gene (p=0.04). Our results suggest that minor allele A of ESR1 gene is associated with the development of arterial hypertension in men. Reduced content of ApoE in blood serum of men with arterial hypertension was associated with APOE4 gene polymorphism. However, increased level of NO did not depend on polymorphic genotypes GG and GT of eNOS gene. These polymorphisms are of specific interest as additional markers of genetic predisposition to the development of arterial hypertension in middle-age men.
