Abstract

- Transforming growth factor beta (TGF beta) is a key regulator of epithelial-tomesenchymal transition (EMT) during embryogenesis and in tumors. The effect of TGF beta, on EMT, is conveyed by induction of the pro-invasive transcription factor Snail1. In this study, we report that TGF beta stimulates Snail1 sumoylation in aggressive prostate, breast and lung cancer cells. Sumoylation of Snail1 lysine residue 234 confers its transcriptional activity, inducing the expression of classical EMT genes, as well as TGF beta receptor I (T beta RI) and the transcriptional repressor Hes1. Mutation of Snail1 lysine residue 234 to arginine (K234R) abolished sumoylation of Snail1, as well as its migratory and invasive properties in human prostate cancer cells. An increased immunohistochemical expression of Snail1, Sumo1, T beta RI, Hes1, and c-Jun was observed in aggressive prostate cancer tissues, consistent with their functional roles in tumorigenesis.
