Abstract
The transforming growth factor β (TGFβ) is involved in a whole range of biological functions, from cell growth to cell differentiation and apoptosis. The role of TGFβ in epithelial-mesenchymal-transitions (EMTs) has been shown for both embryonic development and tumorigenesis. All three TGFβ mammalian isoforms-TGFβl, TGFβ2 and TGFββcan regulate EMTs, with distinct outcomes depending on the tissue and on the state of cell differentiation. This diversity in the TGFβ response relies on a complex network of signals starting with different sets of TGFβ receptors and subsequently involving distinct TGFβ-dependent pathways. The purpose of this review is to recapitulate the current knowledge on the various signaling pathways—including the Smads, Ras, p38MAPK, RhoA and PI3K-which, upon activation by TGFβ can together give rise to TGFβ—induced EMT phenotypes.
