Abstract: SUMMARY 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…
