[The role of single nucleotide polymorphisms in GIPR gene in the changes of secretion in hormones and adipokines in patients with obesity with type 2 diabetes].

The relationship between the rs2302382, rs8111428 and Glu354Gln (rs1800437) polymorphisms in GIPR (glucosedependent insulinotropic polypeptide receptor) gene and plasma levels of mediators involved in the regulation of carbohydrate metabolism in obese patients with type 2 diabetes (before and after a test breakfast) was investigated. The contribution of polymorphic variants of rs2302382, rs8111428 in GIPR gene in the predisposition to type 2 diabetes in individuals belonging to the Slavic population of Russia was found. Polymorphisms rs2302382 and rs8111428 in the GIPR gene were characterized by the nonequilibrium cohesion.

[The chemerin production changes in obese patients with different carbohydrate metabolism state].

Chemerin is a mediator of adipose tissue involved in the regulation of many processes, including lipogenesis, and inflammatory response. The role of chemerin in the development of insulin resistance has been insufficiently studied and needs detailed understanding. The aim of the study was to investigate chemerin production in obese patients with different states of carbohydrate metabolism.

The role of production of adipsin and leptin in the development of insulin resistance in patients with abdominal obesity.

We investigated the tissue-specific features of the production of adipokines (leptin and adipsin) by adipose tissue in obese patients depending on the degree of obesity and the state of carbohydrate metabolism. An increase in the content of adipsin and leptin in the blood plasma was found. In patients with varying degrees of obesity with and without type 2 diabetes mellitus (DM 2), we determined the level of tissue-specific expression of LEP and CFD genes encoding leptin and adipsin, respectively.

Association of Glu298Asp Polymorphism of Endothelial NO Synthase Gene with Metabolic Syndrome Development: a Pilot Study.

We studied association of single nucleotide polymorphism Glu298Asp (rs1799983) of the NOS3 gene with the risk of metabolic syndrome in the Slavic population. Blood samples were obtained from 128 patients with metabolic syndrome and 100 healthy individuals. Polymorphism Glu298Asp of the NOS3 gene was genotyped by allele-specific PCR.
