title: Suppression of tumor suppressors in prostate cancer: the emergence of a novel oncogenic pathway.
abstract: Elucidating oncogenic pathways in prostate cancer is an arduous task. In this issue of Cancer Cell, Yu and colleagues show that repression of Adrenergic Receptor Beta-2 gene expression by Enhancer of Zeste 2 results in acquisition of transforming activities. It is interesting that these activities point to a role for GTPases as important regulators of transformation in prostate cancer cells. They further implicate epithelial-mesenchymal transition as a biologic end point in this process. Overall, on the basis of their findings, the authors nominate a novel oncogenic pathway for prostate cancer that deserves critical thought and attention.
