Overexpression of Transforming Growth Factor β1 in Malignant Prostate Cells is Partly Caused by a Runaway of TGF-β1 Auto-induction Mediated Through a Defective Recruitment of Protein Phosphatase 2A by TGF-β Type I Receptor

These results suggest that TGF-β1 overexpression in malignant cells is caused, at least in part, by a runaway of TGF-β1 auto-induction through ERK activation because of a defective recruitment of PP2A-Bα by TβRI.
