lncRNA RMST is associated with the progression and prognosis of gastric cancer via miR-204-5p

Abstract

Abstract Background Exploring novel biomarkers for gastric cancer holds promise for enhancing patients’ therapy and survival rates. lncRNAs and miRNAs have emerged as important biomarkers for various human cancers. However, the role of lncRNA RMST (RMST) in gastric cancer development and the mechanism underlying its function remains unclear. Results Significant upregulation of RMST was observed in gastric cancer tumor tissues. RMST levels showed strong correlation with patients’ lymph node metastasis and TNM stage and serving as a predictor of adverse prognosis RMST negatively regulated miR-204-5p, which in turn mediated the inhibitory effects of RMST knockdown on gastric cancer cell growth and metastasis. Conclusion RMST served as both a prognostic biomarker and tumor promoter by modulating miR-204-5p. Inhibiting RMST could represent a novel and potential therapeutic strategy for gastric cancer.
