Purine salvage promotes treatment resistance in H3K27M-mutant diffuse midline glioma
Abstract Background Diffuse midline gliomas (DMG), including diffuse intrinsic pontine gliomas (DIPGs), are a fatal form of brain cancer.These tumors often carry a driver mutation on histone H3 converting lysine 27 to methionine (H3K27M).DMG-H3K27M are characterized by altered metabolism and resistance to standard of care radiation (RT) but how the
