Small interfering RNA (siRNA) of FGD5-AS1 or scramble siRNA was transfected into U87 cell lines to examine the role of FGD5-AS1 on glioma development. The proliferation of glioma cells was tested by Cell Counting Kit-8 (CCK-8), the migration and invasion of glioma cells were tested by transwell assay without matrigel or with matrigel. Western blot was used to detect the protein expression, and XAV-939 was used to inhibit wnt/β-catenin pathway. The effect of FGD5-AS1 on tumorigenesis of glioma was confirmed by xenograft nude mice model.Results: FGD5-AS1 was significantly increased in glioma tissues and cells. Loss of FGD5-AS1 inhibited the proliferation, migration and invasion of U87 cells. Furthermore, overexpression of FGD5-AS1 increased the mRNA and protein levels of β-catenin and cyclin D1. Blocking of wnt/β-catenin using XAV-939 reversed the promotion role of FGD3-AS1 on glioma cells’ migration and invasion. The in vivo tumor growth assay showed that FGD3-AS1 accelerated glioma tumorigenesis with activating wnt/β-catenin pathway.Conclusion: Our research emphasized FGD5-AS1 acting as an oncogene by regulating wnt/β-catenin signaling pathway, thus providing some novel experimental basis for clinical treatment of glioma.Keywords: lncRNA FGD5-AS1, glioma, cell proliferation, migration, wnt/β-catenin pathway
