Abstract:

Objective  To investigate the effect of microRNA (miR)-138 regulation of Wnt signaling pathway on the biological behavior of human glioma cells in vitro.    Methods  Glioma cell lines U-87MG and U251 were selected and randomly divided into blank group, miR-NC group, miR-138 mimics group and miR-138 inhibitor group. Real-time PCR was used to detect the miR-138 expression in each group; MTT, flow cytometry, Transwell assay and scratch assay were used to detect proliferation, apoptosis, invasion and migration ability of each group respectively, and Western blotting was used to detect Wnt pathway related protein expression in each group.   Results  The miR-138 expression level was higher in the miR-138 mimics group compared with the remaining 3 groups, and that in the miR-138 inhibitor group was lower than that in the blank group and the miR-NC group (P<0.05); Compared with the blank group, the cell proliferation rate was lower in the miR-138 mimics group and higher in the miR-138 inhibitor group, and was time-dependent(P<0.05); The apoptosis rate in the miR-138 mimics group was higher than that in the blank group, miR-NC group, and miR-138 inhibitor group, while the apoptosis rate in the miR-138 inhibitor group was lower than that in the rest other groups(P<0.05); The number of cell-invading cells in the miR-138 mimics group was lower than that in the blank group, miR-NC group, and miR-138 inhibitor group, while all miR-138 inhibitor group were higher than the remaining three groups (P<0.05); The cell migration rate of miR-138 mimics group was lower than that of blank group, miR-NC group and miR-138 inhibitor group, while all miR-138 inhibitor group were higher than the remaining three groups (P<0.05); Wnt3a, Wnt1, glycogen synthase kinase 3β(GSK-3β)  and β-catenin protein expression in the miR-138 mimics group was lower than that in the blank group, miR-NC group, and miR-138 inhibitor group; While miR-138 inhibitor groups were higher than the remaining three groups(P<0.05).   Conclusion  MiR-138 overexpression effectively inhibite the proliferation, invasion and migration of glioma cells and promote their apoptosis, probably achieved by pathway inhibition of the Wnt signaling pathway.
