Abstract: INTRODUCTION: Glioma is a highly aggressive malignant tumor with high mortality, which is prone to metastasis and recurrence. This study investigated the biological function and related mechanism of action of the long non-coding RNA SNHG22 (lncRNA SNHG22; SNHG22) on glioma cells and its prognostic value. MATERIAL AND METHODS: The relative expression levels of SNHG22 and miR-27b-3p in the included glioma patients were detected by real-time quantitative PCR (RT-qPCR). The cell counting kit-8 (CCK-8) proliferation assay and Transwell assay confirmed the effect of knockdown of SNHG22 on the biological function of glioma cells. Luciferase activity characterized the mechanism of SNHG22 targeting miR-27b-3p. Additionally, Kaplan-Meier and multivariate Cox analyses were performed to evaluate the effect of SNHG22 on patient survival. RESULTS: In glioma tissues and cells, compared to normal samples as controls, SNHG22 expression was increased and the expression of miR-27b-3p was decreased. Silencing SNHG22 suppressed the proliferation, migration and invasion levels of glioma cells. SNHG22 directly targets miR-27b-3p to regulate tumor progression. Low expression of SNHG22 was more conducive to the survival of patients than high expression of SNHG22. CONCLUSIONS: The lncRNA SNHG22 regulated the progression of glioma by targeting miR-27b-3p, which reflected the prognostic potential of SNHG22 and provided a meaningful theoretical reference for the treatment of glioma patients.
