Abstract
miRNAs are endogenous 19- to 25-nt noncoding RNAs that can negatively regulate gene expression by directly cleaving target mRNA or by inhibiting its translation. Recent studies have revealed that miRNA plays a significant role in gastric cancer development either as a tumor suppressor gene or oncogene. miRNA-single-nucleotide polymorphisms (SNPs), as a novel class of functional SNPs/polymorphisms, have been identified as candidate biomarkers for gastric cancer susceptibility. On the basis of recent data, the present review summarizes current knowledge of the functional effects of miRNA-SNPs and their importance as candidate gastric cancer biomarkers. Additionally, this review also includes a meta-analysis of the most frequently studied miRNA-SNPs in gastric cancer.
Core tip: Host genetic susceptibility plays an important role in gastric carcinogenesis. In this review, we summarize current knowledge about the functional effects of miRNA-single-nucleotide polymorphisms (SNPs) and their importance in gastric cancer susceptibility. Furthermore, we also conduct a simple meta-analysis about most frequently studied miRNA-SNPs (rs11614913 in miR-196a-2, rs895819 in miR-27a and rs2910164 in miR-146a) in gastric cancer.
