GENE POLYMORPHISM ANALYSIS OF CHEMOKINES, CHEMOKINE RECEPTORS, ACUTE PHASE PROTEINS, AND CD14 IN FEMALE OBESITY DEVELOPMENT

Abstract

In the present study, we have investigated frequency of genotypes and functional alleles of genes encoding chemokines (CXCL12 rs1801157, CCL2 rs1024611), chemokine receptors (CCR5 del32, CX3CR1 rs3732378), acute phase proteins SAA rs1136743, and CD14 rs2569190 polymorphisms among Tatar obese or overweight women from the Republic of Bashkortostan.The group of patients comprised unrelated women with obesity (BMI ≥ 30 kg/m2, n = 225), females with overweight (BMI 25.0-29.9 kg/m2, n = 184), and control group of women (n = 327) BMI < 25.0 kg/m2. Genotyping was performed by PCR-RFLP analysis. Patients and controls differed in such parameters as body weight (p = 0.00001), BMI level (p = 0.001) and fasting glucose level (p = 0.0001).An association was revealed between obesity and AG-AA genotypes (p = 0.007) and A allele (p = 0.003) of polymorphic locus rs3732378 of CXCR1 gene, as well as TT genotype (p = 0.027) and T allele (p = 0.021) of polymorphic locus rs1136743 of SAA gene. It has been shown that the AA genotype of polymorphic locus rs3732378 of the CX3CR1 gene is associated with increased body weight (p = 0.002) and elevated BMI (p = 0.018); the GG genotype of polymorphic locus rs1024611 of the CCL2 gene is associated with elevated fasting glucose level (p = 0.001).As based on clinical and genetic data and using logistic regression, some statistically significant differences were revealed, which allow to predict development of obesity in Tatar women.
