Introduction. Advanced cancers are well-known to secrete transforming growth factor-β (TGF-β), which, despite its potent growth inhibitory function to normal epithelial cells, promotes epithelial-mesenchymal transition (EMT) and metastasis due to contextual changes that have occurred in the tumor cells (1, 2).Induction of EMT by TGF-β also …Another TGF-β induced SMAD-independent pathway is the JNK/P38 pathway via the activation of TGF-β activated kinase 1 (TAK1). JNK itself can phosphorylate R-SMAD directly, thus, turning on the EMT program. Both JNK and P38 can work synergistically with SMADs to promote TGF-β induced apoptosis [70,77].The induction of EMT by TGF-β was first recognized in cell culture.
