Abstract
Transforming growth factor (TGF)-β is an important paracrine factor in tumorigenesis. Ligand binding of the type I and II TGF-β receptors initiate downstream signaling. The role of stromal TGF-β signaling in prostate cancer progression is unknown. In mice, the conditional stromal knockout of the TGF-β type II receptor expression (Tgfbr2fspKO) resulted in the development of prostatic intraepithelial neoplasia and progression to adenocarcinoma within 7 months. Clinically, we observed a loss of TGF-β receptor type II expression in 69% of human prostate cancer-associated stroma, compared to 15% of stroma associated with benign tissues (n=140, P-value
