Abstract:The malignant transformation of human epithelial cells is generally described as a multistep process resulting from the accumulation of five to seven rate-limiting changes. Here, we challenge this dogma and demonstrate that this number is radically reduced when cells undergo an epithelial-mesenchymal transition (EMT). EMT is an embryonic transdifferentiation process that consists of the conversion of polarized epithelial cells into motile mesenchymal ones. EMT-inducing transcription factors, including Twist an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
