In spite of a large number of transforming growth factor β1 (TGF-β1)-regulated genes, the nature of its targets with roles in transformation continues to be poorly understood. Here we discovered that TGF-β1 stimulates transcription of metastasis associated protein 1 (MTA1), a dual master coregulator, in epithelial cells, and that MTA1 status is a determinant of TGF-β1-induced epithelial-to-mesenchymal transition phenotypes. In addition, we found that MTA1/Pol II/AP1 coactivator complex interacts with the FosB-gene chromatin and stimulates its transcription, and FosB in-turn, utilizes FosB/HDAC2 complex to repress E-cadherin expression in TGF-β1 stimulated mammary epithelial cells. These findings suggest that TGF-β1 regulates the components of EMT via stimulating the expression of MTA1 which in turn, induces FosB to repress E-cadherin expression and thus, revealed an inherent function of MTA1 as a target and effector of TGF-β1 signaling in epithelial cells.
