Epith.lial-mesench.mal transition (EMT) is a h.gh.y conserved process th.t h.s been well ch.racterised in embryogenesis. Studies h.ve sh.wn th.t th. aberrant activation of EMT in adult epith.lia can promote tumour metastasis by repressing cell adh.sion molecules,including epith.lial (E)-cadh.rin. Reduced intracellular adh.sion may allow tumour cells to disseminate and spread th.ough.ut th. body. A number of transcription proteins of th. Snail superfamily h.ve been implicated in EMT. Th.se proteins h.ve been sh.wn to be over-expressed in advanced gastrointestinal (GI) tumours including oesoph.geal adenocarcinomas,colorectal carcinomas,gastric and pancreatic cancers,with.a concomitant reduction in th. expression of E-cadh.rin. Regulators of EMT may provide novel clinical targets to detect GI cancers early,so th.t cancers previously associated with.a poor prognosis such.as pancreatic cancer can be diagnosed before th.y become inoperable. Furth.rmore,ph.rmacological th.rapies designed to inh.bit th.se proteins will aim to prevent local and distant tumour invasion.
