Polycomb deficiency drives a FOXP2-high aggressive state targetable by epigenetic inhibitors

Delineating the specific role of Polycomb Repressive Complex 2 (PRC2) in various cancer systems is desirable as inhibitors for EZH2 inhibitors are approved for some cancers. Here the authors show haplo- and full-insufficiency of EZH2 drive divergent phenotypes in lung cancer. 3D tumoroids recapitulate transcriptional profiles, including FOXP2 derepression, and drug responses of in vivo tumors
