PRC2 loss amplifies Ras signaling in cancer

Nat Genet. 2014 Nov;46(11):1154-5. doi: 10.1038/ng.3124.

Abstract

The histone-modifying PRC2 complex has an ambiguous role in cancer, bearing both oncogenic and tumor-suppressive features depending on cell type. Studies of malignant peripheral nerve sheath tumors (MPNSTs) have now identified loss-of-function mutations altering PRC2 subunits, leading to the amplification of Ras-driven transcription and conferring vulnerability to BRD4 inhibitors.
