The DNA repair proteinO6-methylguanine-DNA methyltransferase (MGMT) might interfere with alkylating agent chemotherapy in patients with glioma or glioblastoma. In this Review, Wick and colleagues discuss how epigenetic silencing of the MGMT gene via promotor methylation is associated with improved response to chemotherapy, and with improved survival, in patients with glioblastoma and other gliomas. The authors also highlight the usefulness of MGMTpromotor methylation as a biomarker for both clinical practice and the design of treatment trials.
