Recent evidences suggest the involvement of the Vacuolar H+ ATPase (V-ATPase) in the development and/or progression of Glioblastoma Multiforme (GBM). This proton pump could be a valid therapeutic target but more in-depth studies are necessary. The aim of this study is to better define the in vitro effects on Glioma Stem Cell (GSC) primary cultures viability of single and combined treatment with Bafilomycin-A1 (Baf-A1), a V-ATPase inhibitor, and Temozolomide (TMZ), the chemotherapeutic agent currently used to treat GBM patients. We found out that GSC were resistant to TMZ and more sensitive to treatments with Baf-A1 and that the two drugs exerted a synergistic effect when administered together.
