Pea3 transcription factors and wnt1-induced mouse mammary neoplasia.
The role of the PEA3 subfamily of Ets transcription factors in breast neoplasia is controversial.Although overexpression of PEA3 (E1AF/ETV4), and of the related factors ERM (ETV5) and ER81 (ETV1), have been observed in human and mouse breast tumors, PEA3 factors have also been ascribed a tumor suppressor function.Here, we utilized the MMTV/Wnt1 mou
