[Molecular genetic aspects of endothelial dysfunction in individuals exposed to mercury]

[Article in Russian]

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.
