Glioblastoma multiforme (GBM) is the most prevalent type of malignant cancer in the adult central nervous system; however, its mechanism remains unclear. Angiomotin‑like 2 (AMOTL2) is a member of the motin family of angiostatin‑binding proteins. It has been reported as an oncogene in cervical and breast cancer, but its association with glioma remains unknown. The aim of the present study was to investigate AMOTL2‑regulated processes in glioma cell lines using extensive assays and certain bioinformatics tools. These results revealed that AMOTL2 was downregulated in high‑grade glioma cells and tissues, with patients with glioma exhibiting a high AMOTL2 expression having a higher survival rate. The results of the glioma cell phenotype experiment showed that AMOTL2 suppressed GBM proliferation, migration and invasion. In addition, immunoblotting, co‑immunoprecipitation and immunofluorescence assays demonstrated that AMOTL2 could directly bind to β‑catenin protein, the key molecule of the Wnt signaling pathway, and regulate its downstream genes by regulating β‑catenin nuclear translocation. In conclusion, the present study demonstrated that AMOTL2 inhibited glioma proliferation, migration and invasion by regulating β‑catenin nuclear localization. Thus, AMOTL2 may serve as a therapeutic target to further improve the prognosis and prolong survival time of patients with glioma.
