Histone H3.3 Mutations Drive Pediatric Glioblastoma through Upregulation of MYCN

Abstract

We provide the mechanistic explanation for how the fi rst histone gene mutation inhuman disease biology acts to deliver MYCN, a potent tumorigenic initiator, into a stem-cell compartment of the developing forebrain, selectively giving rise to incurable cerebral hemispheric GBM. Using synthetic lethal approaches to these mutant tumor cells provides a rational way to develop novel and highly selective treatment strategies
