abstract：:The Wnt signaling pathway plays a pivotal role in vertebrate early development and morphogenesis. Duplin (axis duplication inhibitor) interacts with beta-catenin and prevents its binding to Tcf, thereby inhibiting downstream Wnt signaling. Here we show that Duplin is expressed predominantly from early- to mid-stage mo...
