Interleukin-6 polymorphism and prostate cancer risk in population of Eastern Croatia.

چکیده
Recent studies suggest that chronic inflammation is crucial in the development and progression of prostate cancer (CaP). Interleukin-6 (IL-6) is a proinflammatory cytokine that plays an important role in intraprostatic inflammation and thus carcinogenesis. The -174G > C polymorphism of IL-6 gene has been associated with high IL-6 producer phenotype and an increased risk for CaP. The aim of this study was to evaluate the association between the mentioned IL-6 polymorphism and CaP risk, as well as to compare the genotype frequency between the different tumour grades of CaP, in population of Eastern Croatia. We analyzed the IL-6 polymorphism in 120 CaP patients and 120 controls with benign prostatic hyperplasia (BPH). CaP patients and BPH controls did not statistically differ in studied IL-6 polymorphism. Furthermore, high IL-6 producer genotypes (GG or GC) were more frequent in controls than in CaP group (86.7% vs 80.8%, respectively, p = 0.147). Also, no statistically significant difference in IL-6 high and low producer genotype frequency was noticed between well, moderately and poorly differentiated tumours. Our results, taken together with other studies on the subject, suggest that IL-6 - 174 single nucleotide polymorphism (SNP) distribution may differ between various ethnic groups and that a single cytokine gene polymorphism has probably just a minor effect on CaP susceptibility. Further studies should be performed to clarify the link between SNPs of different cytokines and the risk for CaP.

Background and Objective: Prostate cancer is among the five common cancers in males. It is second cancer in terms of the age-standardized rate (ASR) (ASR=16.6) in Iran. The rs2735839 G/A, an intergenic polymorphism is located on chromosome 19q13.33 at 600 base pairs of the KLK3 gene untranslatable region. This gene which codes prostate-specific antigen (PSA) is used in the screening and diagnos...

Association Study of miR-124-a-3 Gene rs34059726 Polymorphism with Prostate Cancer in Gonbad Kavous
Background: MiRNAs are one of the most important genetic regulators that regulate more than 50 percent of the human genome. MiR-124-a-3 is a tumor suppressor miRNA which its expression dramatically reduced in prostate cancer tumor cells. Since miRNA binding to the transcript of target genes by seed sequence, any mutations and changes in this region could be effective on its performance and iden...
