Abstract

The article deals with frequency data on polymorphism of candidate genes participating in endothelial dysfunction (EDN1 Lys198Asn, NOS3 T786C, AGT Thrl74Met and AGT Met23SThr) in totality with concentrations of their active substances in individuals exposed to mercury. Findings are changes in levels of nitrogen oxide, endothelin-1, angiotensin II metabolites in examinees including those without cardiovascular diseases. The genetic conditionality is connected with unfavorable genotypes of polymorphic variants - Met235Thr of AGT gene and Lys198Asn of EDNI gene. Changes in levels of biochemical markers of endothelial dysfunction in individuals exposed to mercury indicate serious endothelial function disorders and are not genetically determined processes.

[接触汞个体内皮功能障碍的分子遗传学方面]。
本文研究了参与内皮功能障碍的候选基因(EDN1 Lys198Asn, NOS3 T786C, AGT Thrl74Met和AGT Met23SThr)在汞暴露个体中活性物质浓度的多态性频率数据。结果显示,包括无心血管疾病者在内的受试者一氧化氮、内皮素-1、血管紧张素II代谢物水平均有变化。遗传条件与AGT基因的Met235Thr和EDNI基因的Lys198Asn多态性变异的不利基因型有关。在接触汞的个体中,内皮功能障碍的生化标志物水平的变化表明内皮功能严重紊乱,这不是遗传决定的过程。
