Background Long noncoding RNAs (lncRNAs) are from the family of noncoding RNAs. Existing studies have shown that lncRNAs are involved in many biological processes and are strongly related to the occurrence and development of tumors. Recent studies have indicated that lncRNA GIHCG participates in the progression of many cancers by adjusting cell proliferation and migration. Gastric cancer (GC) is a prevalent malignant tumor that arises from gastric epithelium. This study mainly explored the influence of GIHCG on GC and its underlying mechanism. Methods GIHCG expression was detected in GC through quantitative real‐time polymerase chain reaction while the relationship of GIHCG with miR‐1281 and miR‐1281 with TLE1 was verified using dual luciferase reporter gene assay. The influence of GIHCG, miR‐1281 and TLE1 on cell function was verified using cell counting Kit‐8 (CCK‐8) and Transwell experiment. Results In GC, GIHCG was significantly overexpressed and significantly increased cell proliferation and migration, with the possible mechanism of upregulatingTLE1 expression through adsorption of miR‐1281. Conclusion Taken together, we revealed the role of GIHCG/miR‐1281/TLE1 in GC and provided a new perspective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
