    ABSTRACT: Several genes encoding DNA repair molecules have been proposed as cancer-susceptibility genes. Many studies have suggested that SNPs in XRCC4 could be implicated in altering the risk of prostate cancer (PCa). We examined the role of the functional variant (-652T>G) in the XRCC4 promoter in PCa. The transcriptional activity of XRCC4 gene was measured by luciferase assay. We performed real-time PCR/immunohistochemical assay to verify the association between expression level of XRCC4 mRNA/protein and XRCC4 -652T>G polymorphism. In addition, electrophoretic mobility shift assay (EMSA) was used to confirm whether this polymorphism has an effect on binding ability of the transcription factor. We found that the G variant significantly increased the transcription activity of the XRCC4 gene and the binding ability of transcriptional factor GATA-1 to the XRCC4 promoter. Furthermore, the results suggested that the XRCC4 protein and mRNA were overexpressed in individuals who carried the -652G allele compared to carriers of the -652T allele. In addition, the expression of XRCC4 in PCa tissues was lower than in adjacent normal tissues. Our data suggest that the XRCC4 promoter -652G>T polymorphism is functional and may influence genetic susceptibility to prostate cancer. Case-control studies are required to validate our findings in the future.

    ABSTRACT: To explore the reported association of SNP marker rs10993994 with prostate cancer identified by two independent in two genome-wide association studies (GWAS) further, we performed a case-control study in southern Chinese Han population. Consequently, we detected the serum levels of MSMB expression with different genotypes in the cases and controls to characterize the functional consequences of rs10993994. Two hundred fifty-one prostate cancer and 258 control subjects were included in the cancer association study and 90 serum samples were used to test the expression of the MSMB by Enzyme-linked immunosorbent assay (ELISA). We found that the T allele displayed an increased prevalence of prostate cancer compared with the C allele (OR = 1.30, 95% CI = 1.01-1.67, P = 0.040). Moreover, the prostate cancer patients carrying CT/TT genotype had significantly decreased serum MSMB levels compared to those with CC genotype (16.32 +/- 3.98 microg/L vs. 19.33 +/- 4.27 microg/L, P = 0.022). rs10993994 in MSMB promoter affects serum MSMB expression, contributes to the genetic predisposition to prostate cancer in southern Chinese Han population.
