title: Roles of competing endogenous RNAs in gastric cancer.
abstract: Long noncoding RNA (lncRNA) is >200 nucleotides long and lacks coding ability. LncRNA was regarded as transcript noise, until emerging results showed its roles in development, homeostasis and carcinogenesis. LncRNAs containing microRNA (miRNA) response elements could compete with the miRNA target gene and regulate its expression through decreasing free functional miRNA. Such lncRNA is called competing endogenous RNA (ceRNA), and the 'lncRNA-miRNA' interaction appreciably enriches the world of RNA-RNA regulation. Gastric cancer involves dysregulation of both protein-coding genes and noncoding genes, and the ceRNA regulatory mechanism may participate in this pathogenic process. In this review, we discuss recent findings on the roles of ceRNAs in gastric carcinogenesis.
