This study confirms the preservation of EZH2 overexpression in 22 patient-derived orthotopic xenograft models of pediatric brain tumors. The authors demonstrate the activity of an FDA-approved EZH2 inhibitor, tazemetostat, alone and in combination with radiation in a subset of the models, and identifies EZH2-negative cells as potential cause of therapy resistance.
