Abstract:A long-standing biological question is how DNA cis-regulatory elements shape transcriptional patterns during metazoan development. The use of reporter constructs, cell culture and computational modeling has made enormous contributions to understanding this fundamental question, but analysis of regulatory elements in their natural developmental context is an essential but rarely used complement. Here, we edited Notch-dependent cis-regulatory elements in the endogenous C. elegans sygl-1 gene, which encodes a key… 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.
