Abstract

Cancer epigenetics in the driver's seat Recent cancer genome projects unexpectedly highlighted the role of epigenetic alterations in cancer development. About half of human cancers were found to harbor mutations in chromatin proteins. In a Review, Flavahan et al. propose that chromatin and epigenetic aberrations have the potential to confer on cells the full range of oncogenic properties represented in the classic “hallmarks” depiction of cancer. They suggest that genetic, environmental, and metabolic factors can make chromatin aberrantly permissive or restrictive. Permissive chromatin creates a state of “epigenetic plasticity,” which can activate oncogene expression or cell fate changes that drive cancer development. Science , this issue p. eaal2380
