title: Single-nucleotide polymorphisms of microRNA processing machinery genes are associated with risk for gastric cancer.
abstract: Recent studies demonstrate that microRNA-related single-nucleotide polymorphisms (miR-SNPs) are associated with the development of numerous human cancers. In this study, we investigated six miR-SNPs in microRNA processing machinery genes, including rs11077 of the XPO5 gene, rs14035 of the RAN gene, rs3742330 of the Dicer gene, rs9623117 of the TNRC6B gene, rs197412 of the GEMIN3 gene, and rs2740348 of the GEMIN4 gene, in gastric cancer patients and subsequently evaluated their potential roles in gastric cancer risk in a case control study. The results indicate that the C/C genotype of rs14035 from RAN, the A/A genotype of rs3742330 from Dicer, and the T/T genotype of rs9623117 from TNRC6B are significantly associated with gastric cancer risk. In conclusion, these miR-SNPs can be used as predictive biomarkers in gastric cancer.
