Abstract

Glioblastoma is the most aggressive type of brain tumor and has a poor prognosis. Increased levels of cholesteryl ester and simultaneous expression of acyl‑CoA:cholesterol acyltransferase 1 (ACAT1) in tumor cells indicated that cholesterol esterification is critical to tumor growth. The present study confirmed that human glioblastoma tissues as well as the glioblastoma cell line U251‑MG showed significant expression of ACAT1. ACAT1 expression in U251‑MG cells increased in a cell proliferation‑dependent manner. K604, a selective ACAT1 inhibitor, suppressed the proliferation of U251‑MG cells and downregulated the activation of Akt and extracellular signal‑regulated kinase in proliferating glioblastoma cells. These results suggested that ACAT1 may be a therapeutic target for the treatment of glioblastoma, with K604 as an effective therapeutic agent.
