CYMP-AS1 Promotes Ovarian Cancer Progression by Enhancing the Intracellular Translocation of hnRNPM and Reducing the Stability of AXIN2 mRNA
Ovarian cancer (OC) is a representative malignancy of the female reproductive system, with a poor prognosis. Long non-coding RNAs (lncRNAs) crucially affect tumor development. This study aimed to identify lncRNAs that potentially participated in OC. LncRNA expression in cells and tissues was quantified using reverse transcription-quantitative PCR, while fluorescence This study identified a previously unreported lncRNA, CYMP-AS1, which exhibits increased expression in the cytoplasm of OC tissues and cells. Knockout of CYMP-AS1 reduced the OC cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT). CYMP-AS1 directly interacts with heterogeneous nuclear ribonucleoprotein M (hnRNPM), inducing its intracellular translocation and reducing the stability of Axis inhibition protein 2 (AXIN2) mRNA. This process ultimately elevated the expression of Wnt/β-catenin signaling pathway-related proteins. This study confirms CYMP-AS1 as a novel biomarker in OC progression and suggests that the CYMP-AS1/hnRNPM/AXIN2 axis may offer an innovative strategy for OC treatment.
