Glioblastoma is the most frequent primary malignant brain tumor in adults. Oxysterols are oxidation products of cholesterol generated by enzymatic reactions. 27‑hydroxycholesterol (27‑HC), an oxysterol, is an abundant metabolite of cholesterol. 27‑HC significantly accelerates mammary cancer growth, proliferation and progression in experimental models. However, to the best of our knowledge, the effect of 27‑HC on glioblastoma has not been studied. Therefore, the present study aimed to determine the exact role of 27‑HC in glioblastoma. The present study demonstrated that 27‑HC promoted proliferation, epithelial to mesenchymal transition, colony formation, migration and invasion of U251 and U118 MG glioblastoma cells. Treatment with 27‑HC was also associated with an increase in the formation of glioblastoma‑initiating cells in U251 and U118 MG cell lines. Additionally, it was observed that high levels of 27‑HC in glioblastoma tissues were associated with poor outcome in patients. In conclusion, 27‑HC, a primary metabolite of cholesterol, may serve an important role in the progression of glioblastoma.
