https://www.selleckchem.com/products/sc-43.html Dual-Luciferase assay was conducted to detect the ability of miR-449b-5p to regulate the 3'UTR (untranslated regions) of WNT2B. TOP/FOP ratio was used to evaluate the activity of Wnt/β-catenin signaling pathway. Results Down-regulation of miR-449b-5p expression was found in both human glioblastoma tissues and cell lines, which was negatively associated with the clinical stages. Up-regulation of miR-449b-5p inhibited tumor spheres formation, cell viability and proliferation ability of glioblastoma cells. The expression levels of WNT2B and nuclear β-catenin were negatively associated with miR-449b-5p levels in glioblastoma cells. MiR-449b-5p inhibited Wnt/β-catenin signaling by targeting WNT2B. Conclusions MiR-449b-5p acts as a tumor suppressor and retards the oncogenesis of glioblastoma, which is achieved via inactivation of Wnt/β-catenin signaling by directly targeting WNT2B.Objective Glioma is a highly aggressive and lethal brain tumor. Anesthetics have been shown to have important effects on the biological characteristics of cancer cells. Nevertheless, the molecular mechanism of anesthetic-mediated glioma cells progression remains unclear. Materials and methods Sevoflurane (sev) was employed to treat glioma cells. The biological characteristics (viability, colony formation, apoptosis, cell cycle, migration, and invasion) of glioma cells were determined via Cell Counting Kit-8 (CCK-8), cell colony formation, flow cytometry, PI cytometry, or transwell assays. The protein levels of Cell Cycle Dependent Kinase (CDK) 2, CDK4, E-cadherin, N-cadherin, Vimentin, and Transforming Growth Factor Beta (TGFB) induced factor homeobox 2 (TGIF2) were assessed through Western blot analysis. Glucose consumption and lactate production were measured using special commercial kits. The expression of circular RNA has_circ_0012129 (circ_0012129) and miR-761 was detected via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The rel
