Abstract
© 2008 Landes BioscienceThe TGF-betas are a family of pleiotropic cytokines that mediate diverse effects including the regulation of cell cycle progression, apoptosis, tissue remodelling and epithelial-mesenchymal transition (EMT). These diverse effects allow the TGF-betas to play multiple and even opposing roles in different contexts during embryonal development, tissue homeostasis and cancer progression. We recently reported that the protein tyrosine phosphatase Pez is a novel inducer of TGF-beta signaling, regulating EMT and organogenesis in developing zebrafish embryos, and leading to TGF-beta mediated EMT when over-expressed in vitro in epithelial MDCK cells. A number of mutations in Pez have been shown to be associated with breast and colorectal cancers, although the effect of these mutations on Pez function and their contribution to cancer progression remains unclear. Our finding that Pez regulates TGF-beta signaling is therefore of interest not only in the context of identifying a novel upstream regulator of TGF-beta signaling, but also in implicating the dysregulation of TGF-beta signaling as a possible link between Pez mutation and cancer progression. Here we discuss the implications of our research, in the context of dysregulation of TGF-beta signaling in cancer and other human pathologies.Leila Wyatt and Yeesim Khew-Goodal
