Background/aim: The histone demethylase NO66 regulates gene and protein expression. Epidermal growth factor receptor (EGFR) is a key oncogenic factor for glioblastoma. This study aimed to examine the role of NO66 in glioblastoma.
Materials and methods: The prognostic value of NO66 expression in 263 human glioma tissues and 510 glioblastoma tissues was examined by Kaplan and Meier survival analysis. Immunoblot analysis of EGFR expression, cell proliferation assays and cell cycle analysis were performed in glioblastoma cells after NO66 knockdown.
Results: In 263 human glioma tissues, high levels of NO66 expression correlated with advanced disease stage and poor patient prognosis. In 510 glioblastoma tissues, high levels of NO66 expression also predicted poor patient prognosis. NO66 knockdown reduced EGFR expression and cell proliferation in glioblastoma cells.
Conclusion: High levels of NO66 in glioma and glioblastoma tissues predict poor patient prognosis, and NO66 is required for EGFR expression and glioblastoma cell proliferation.
