Knockdown of long non-coding RNA CCAT2 suppressed proliferation and migration of glioma cells.
Long non-coding RNA colon cancer-associated transcript 2 (CCAT2) is commonly investigated in a number of cancers. However, little is known of its expression and biological function in glioma biology. In the current study, we used quantitative real-time PCR (qRT-PCR) to determine the expression of CCAT2 in glioma tissues. We found that expression of CCAT2 was up-regulated in glioma tissues and significantly correlated with the advanced tumor stage (III/IV). Functional assays in vitro and in vivo demonstrated that knockdown of CCAT2 could inhibit proliferation, cell cycle progression and migration of glioma cells. Further analysis indicated the effect of CCAT2 knockdown on glioma cell phenotype through inhibiting Wnt/β-catenin signal pathway activity. Thus, our study provides evidence that CCAT2 may function as a potential biomarker for glioma.
