Content of adipokines and myokines in the blood of children and adolescents with obesity with polymorphism of the gene of liver triacylglycerol lipase rs2070895

Abstract

BACKGROUND: A special role in the development of obesity is given to the genetic polymorphism of lipid metabolism enzymes, which include triacylglycerol lipase. However, there is still no information about the relationship between the single nucleotide polymorphism (snp) of the triacylglycerol lipase (LIPC) gene and the state of the endocrine function of mesenchymal tissues in childhood and adolescence obesity.AIM: The aim of the work was to study the relationship between snp LIPC for rs2070895 and changes in the content of adipokines, myokines, and the values of blood lipid metabolism in obese children and adolescents with different sexes.MATERIALS AND METHODS: In 96 healthy children and adolescents of different sexes and 98 obese peers, a study was conducted to assess the snp of the LIPC by rs2070895. In the blood serum of the examined, the content of total cholesterol, HDL cholesterol, LDL cholesterol, VLDL cholesterol, triacylglycerols, glucose, activity of alanine aminotransferase and aspartate aminotransferase, as well as the level of leptin, adiponectin, resistin, apelin, irisin, adipsin, myostatin, FGF21, osteocrine, oncostatin M , insulin and asprosin.RESULTS AND DISCUSSION: It has been established that obesity in boys is accompanied by hyperleptinemia, the occurrence of insulin resistance and disorders of blood lipid metabolism. In carriers of the heterozygous allele -250G/A, dyslipidemia and atherogenesis decrease in obesity, but alteration of internal organs increases. In girls with different LIPC genotypes for rs2070895, with obesity, there is an increase in the level of leptin and apelin, as well as irisin and insulin in the blood. In girls with the homozygous allele -250G/G, in addition to that, the content of resistin, asprosin and prolactin decreases in the blood, which is not are typical for girls with the heterozygous allele -250G/A. In obese girls with the heterozygous allele, the levels of adipsin, FGF-21, oncostatin M, and osteocrine increase, which are not typical for obese girls with the homozygous allele. Against the background of changes in the content of adipokines and myokines in girls homozygous for LIPC, obesity occurs dyslipemia, which is not typical for girls with the heterozygous allele -250G/A.CONCLUSION: The snp of LIPC at rs2070895 has sex-dependent effects on the levels of adipokines, myokines, and parameters lipid metabolism in the blood.
