Epithelial–mesenchymal transition (EMT) is a phenotypic conversion that facilitates organ morphogenesis and tissue remodeling. The authors of this Review discuss the phenomenon of EMT in relation to tumor development, and the function of EMT in promoting invasion and metastasis. The roles of ERK1, ERK2 and PI3-kinase, as microenvironmental responsive regulators of EMT are also highlighted.
