(Submitter supplied) Diffuse intrinsic pontine glioma (DIPG) is a fatal malignancy of the childhood pons characterized by a unique lysine-to-methionine substitution in histone-3 at lysine 27 (H3K27M). We show here that the specific Polycomb targets disrupted by H3K27M and resultant oncogenic state is dependent on both the variant of histone-3 and the cell- context in which the mutation occurs. Through primary DIPG tumor characterization and isogenic expression, we show that the same H3K27M mutation displays distinct modes of oncogenic reprogramming and establishes distinct enhancer architecture depending on whether it occurs in genes encoding H3.3 or H3.1. more...
