The transcriptional repressor Snail2 is thought to be crucial for the epithelial-to-mesenchymal transition (EMT) that promotes neural crest delamination from the neural tube; however, little is known about its downstream targets. To this end, we depleted avian Snail2 in the premigratory neural crest using morpholino antisense oligonucleotides and examined effects on potential targets by quantitative PCR. Several dorsal neural tube genes were upregulated by alleviating Snail2 repression; moreover,the cell adhesion molecule cadherin6B was derepressed within 30 minutes of blocking Snail2 translation. Examination of the chick cadherin6B genomic sequence reveals that the regulatory region contains three pairs of clustered E boxes, representing putative Snail2 binding sites. Furthermore, in vivo and in vitro biochemical analyses demonstrate that Snail2 directly binds to these sites and regulates cadherin6B transcription. These results are the first to describe a direct target of Snail2 repression in vivo and in the context of the EMT that characterizes neural crest development.<\/jats:p>","DOI":"10.1242\/dev.02834","type":"journal-article","created":{"date-parts":[[2007,3,7]],"date-time":"2007-03-07T20:12:16Z","timestamp":1173298336000},"page":"1481-1490","source":"Crossref","is-referenced-by-count":207,"title":["Snail2 directly represses cadherin6B during epithelial-to-mesenchymal transitions of the neural crest"],"prefix":"10.1242","volume":"134","author":[{"given":"Lisa A.","family":"Taneyhill","sequence":"first","affiliation":[{"name":"Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward G.","family":"Coles","sequence":"additional","affiliation":[{"name":"Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Bronner-Fraser","sequence":"additional","affiliation":[{"name":"Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042612301588900_REF1","doi-asserted-by":"crossref","unstructured":"Barrallo-Gimeno, A. and Nieto, M.
