Remodelling the malignant phenotype: impact of EMT

Epithelial to mesenchymal transition (EMT) is a highly conserved programme of events essential for normal development. As it underpins cell plasticity, migration and invasion in a number of settings it is an attractive concept to apply to the malignant phenotype. Much is known about the molecular events regulating EMT in a number of model organisms, including Drosophila, sea urchin, zebrafish, xenopus and the chick. It is increasingly apparent that EMT is a highly conserved process, and that discoveries made in these systems provide excellent insights into the understanding of the role of EMT in human malignancies.
