Here, the first genome-wide in vivo RNA interference screens in a mammalian animal model are reported: genes involved in normal and abnormal epithelial cell growth are studied in developing skin tissue in mouse embryos, and among the findings, β-catenin is shown to act as an antagonist to normal epithelial cell growth as well as promoting oncogene-driven growth.
