Abstract

Background: Genetic variants affect the expression of microRNAs (miRNA) resulted in changes in the expression levels of the miRNA target genes that may lead to the increased risk of cancer. The aim of the current study was to investigate the association between the common single-nucleotide gene polymorphism T < C (rs11614913) in MIR196A2 and the risk of developing prostate cancer (PCa) in Chahar Mahal and Bakhtiari Province, Iran.Methods: In this case-control study, 99 patients were enrolled in the case group and 100 healthy controls in the control group. From all participants, 5 ml venous blood sample was collected and DNA was extracted by phenol-chloroform extraction. Specific primers were designed for rs11614913 polymorphism, and this polymorphism was genotyped using High Resolution Melt (HRM) analysis. Hardy-Weinberg equilibrium for the genotypes was tested by chi-squared test. The association between different genotypes and the risk of prostate cancer was investigated by logistic regression analysis.Findings: Among 99 patients, 68 had prostate cancer and 31 had benign prostatic hyperplasia (BPH). Logistic regression analysis showed that those cases with CC genotype had a higher risk of developing prostate cancer [Odds ratio (OR) = 1.08] than T (TT+CT) carriers. Allele frequency analysis revealed that the C allele increased the risk of developing prostate cancer and BPH 1.3 more than T allele.Conclusion: The C allele in rs11614913 polymorphism increases the risk of prostate cancer. Because this polymorphism is present in MIR196A2 gene, evaluation of expression of the miRNA gene and its target genes in patients with prostate cancer could be valuable.
