Genetic and pathophysiological substantiation of polyphenolic grape processing products’ application in the treatment of metabolic syndrome in the population of the Republic of Crimea

Abstract

Adipose tissue in abdominal obesity produces various cytokines, the most important of which is adiponectin (AN). Polymorphism of the AN receptor genes is associated with the risk of metabolic syndrome (MS) and type 2 diabetes mellitus (DM2) development. The aim of the study was to investigate the association of AN genes receptors’ polymorphism with the development of MS and DM2 in the Republic of Crimea as well as the possibility of named pathology correction with polyphenolic functional foods. The study included 100 patients with confirmed diagnosis of DM2 and MS. Genomic DNA was isolated from the whole blood of patients. Gene polymorphism amplification was performed by PCR real-time. The most common genotype of the ADIPOQ gene (rs1501299) among patients with DM2 and MS was GT polymorphism G276T. The most frequent genotypes of the ADIPOR1 gene were AC (rs2275737) – 53.3% and CT (rs2275738) - 50.0%. The most frequent combinations between ADIPOR1 and ADIPOQ genes were AC (rs2275737) /CT (rs2275738) and GT (rs1501299) – 28.6%, as well as AC (rs2275737)/CT (rs2275738) and GG (rs1501299) – 19.7%. Thus, in patients with MS and DM2 in the Republic of Crimea, associations of polymorphism of the genes of the AN receptors with the development of this pathology have been established. It is known that polyphenols of red grape varieties are epigenetic modifiers. Therefore, these products can be included in individual nutrition programs in population groups genetically predisposed to MS and DM2.
