| Abstract: | Gastric cancer is a leading cause of cancer-related deaths. However, the mechanisms underlying gastric carcinogenesis remain largely unclear. The association of non-coding RNAs(nc RNAs) with cancer has been widely studied during the past decade. In general, nc RNAs have been classified as small nc RNAs, including micro RNAs(mi RNAs), and long non-coding RNAs(lnc RNAs). Emerging evidence shows that mi RNAs and lnc RNAs play key roles in the formation and progression of many cancers. In this review, we focus on the regulation of mi RNAs and lnc RNAs in gastric cancer. mi RNAs and lnc RNAs appear to be involved in gastric tumor growth, invasion, and metastasis and in establishment of the gastric tumor microenvironment through various mechanisms. Furthermore, we also discuss the possibilities of establishing mi RNAs and lnc RNAs as potential biomarkers and therapeutic targets for gastric cancer. Taken together, we summarize the emerging roles of nc RNAs in gastric cancer development and their possible clinical significance. |
