ABSTRACT
Objective:
To investigate the targeting relationship between microRNA-153-3p and transforming growth factor-beta 2 (TGFβ2) and its effects on invasion, migration and epithelial-mesenchymal transformation of cultured glioma cells.Methods:
Real-time fluorescence quantitative PCR and Western blotting were used to detect the effects of miR-153-3p on the expressions of TGFβ2 mRNA and protein. Bioinformatics software was used to predict the binding sites of miR-153-3p to TGFβ2. Luciferase reporter assay was used to analyze the targeting relationship between miR-153-3p and TGFβ2. Transwell and wound healing assays were used to detect the effects of miR-153-3p on SHG-44 cells invasion and migration. Western blotting was used to detect the expressions of proteins related to invasion, migration and epithelial-mesenchymal transition.Results:
miR-153-3p mimic inhibited the expressions of TGFβ2 mRNA and protein in SHG-44 cells. Software predicted results showed a continuous binding region between miR-153-3p and TGFβ2. miR-153-3p mimic co-transfected with TGFβ2 wild-type reporter vector significantly decreased the activity of luciferase in the cells (P<0.01). miR-153-3p mimic co-transfected with TGFβ2 mutant reporter showed no significant change in luciferase activity. The number of invasive cells and scratch closure rate of SHG-44 cells transfected with miR-153-3p mimic were significantly decreased. The expression levels of MMP-2, MMP-9 and VEGF were significantly decreased. The expression levels of N-cadherin, Snail-2, Vimentin and Twist were significantly decreased, and the expression level of E-cadherin was significantly increased (P<0.01). The high expression of TGFβ2 alleviated the effect of miR-153-3p on the cell invasion and epithelial mesenchymal transition related proteins in SHG-44.Conclusion:
miR-153-3p inhibits the invasion and migration of cultured glioma cells and epithelial mesenchymal transition by targeting TGFβ2.
