Coordinate Transcriptional Regulation by ERG and Androgen Receptor in Fusion-Positive Prostate Cancers

In this issue of Cancer Cell, Yu and colleagues mapped the genomic binding sites of ERG and androgen receptor, two crucial transcription factors in prostate cancer. There is an extraordinary degree of overlap between binding sites, with the suggestion that ERG inhibits androgen receptor-mediated differentiation and promotes EZH2-mediated dedifferentiation.
