Abstract 2676: Epithelial-mesenchymal transition does not require transcriptional repression of the epithelial programin vivo

Epithelial-mesenchymal transition (EMT), the process by which an epithelial cell loses its adhesion to neighboring cells and acquires a motile, fibroblast-like phenotype, is critical for many aspects of embryogenesis and has been strongly implicated in tumor cell invasion and metastasis. EMT is thought to be primarily regulated at the transcriptional level through repression of epithelial genes by transcription factors such as Snail, Zeb and...
