Canonical Wnt signaling pathway, mediated by the transcription factor β-catenin, plays critical roles in embryonic development, and represents an important therapeutic target. In a zebrafish-based in vivo screen for small molecules that specifically perturb embryonic dorsoventral patterning, we discovered a novel compound, named windorphen, which selectively blocks the Wnt signal required for ventral development. Windorphen exhibits remarkable specificity toward β-catenin-1 function, indicating that t…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
