Metastasis is a fatal complication of prostate cancer, but its mechanisms remain largely unknown. In this report, the authors identify a signaling pathway commonly deregulated in human prostate cancer and describe how it can foster both primary growth and metastatic tumor progression. Epigenetic silencing of the RasGAP DAB2IP by EZH2 overexpression results in aberrant activation of Ras signaling, but also of NF-κB. These two events are mediated by different DAB2IP domains and have distinct roles in localized growth and distant dissemination.
