Impact of MMP-9 Genetic Polymorphism and Concentration on the Development of Coronary Artery Disease in Ukrainian Population.

Coronary artery disease (CAD) is one of the leading causes of death in Europe. It is known that atherosclerosis is the primary risk factor of CAD development. MMP-9 is involved in all stages of atherosclerosis and thus may contribute to CAD emergence. To investigate the influence of MMP-9 on the (CAD) development 25 patients with intact coronary arteries (CA), 40 patients with acute coronary syndrome (ACS), and 63 patients with chronic coronary syndrome (CCS) were enrolled in the study. Real-time PCR was carried out for genotyping on the rs17567-polymorphic locus, and ELISA study was performed to measure the MMP-9 plasma concentration. It was found the lower risk of MI occurrence for AG-carriers (P a =0.023; ORa = 0.299, 95% CI = 0.106-0.848) in Ukrainian population.

Association analysis between HOTAIR RS1899663 single nucleotide polymorphism and clear cell renal cell carcinoma development in Ukrainian population.

OBJECTIVE: The aim: to study the association between rs1899663-polymorphic variant of HOTAIR gene and clear cell renal cell carcinoma (CCRCC) development in Ukrainian population. PATIENTS AND METHODS: Materials and methods: whole venous blood from 101 Ukrainians with CCRCC (42 females and 59 males) and 100 control subjects (34 females and 66 males) were enrolled in the study. DNA extraction was performed using GeneJET Whole Blood Genomic DNA Purification Mini Kit (Thermo Fisher Scientific, USA). Polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) was used for HOTAIR rs1899663 genotyping. The Statistical Package for Social Science software (SPSS, version 17.0, Chicago, IL, USA) was used for all calculations. RESULTS: Results: It was found the lack of association between HOTAIR rs1899663 single nucleotide polymorphism and CCRCC emergence as well as tumor metastasis property in dominant, recessive, over-dominant and additive crude models of inheritance, as well after the adjustment for age, sex, smoking and excessive alcohol consumption (P > 0.05). CONCLUSION: Conclusions: No association was found between HOTAIR rs1899663-polymorphic variant and CCRCC development in Ukrainian population. Further studies with extended samples are required to validate these results.

Association Study between BGLAP Gene HindIII Polymorphism and Type 2 Diabetes Mellitus Development in Ukrainian Population.

Type 2 diabetes mellitus (T2DM) belongs to the diseases with hereditary predisposition, so both environmental and genetic factors contribute to its development. Recent studies have demonstrated that the skeleton realizes systemic regulation of energy metabolism through the secretion of osteocalcin (OCN). Thus, the association analysis between HindIII single nucleotide polymorphism of OCN gene (BGLAP) promoter region and T2DM development in Ukrainian population was carried out. 153 individuals diagnosed with T2DM and 311 control individuals were enrolled in the study. The genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The lack of association between BGLAP HindIII single nucleotide polymorphism (SNP) and T2DM development among Ukrainians was found. Further studies with extended groups of comparison are needed to confirm the obtained results.
