Canonical Wnt Signaling Regulates Atrioventricular Junction Programming and Electrophysiological Properties
7 Nov 2014
Abstract excerpt
RATIONALE: Proper patterning of the atrioventricular canal (AVC) is essential for delay of electrical impulses between atria and ventricles, and defects in AVC maturation can result in congenital heart disease. OBJECTIVE: To determine the role of canonical Wnt signaling in the myocardium during AVC development. METHODS AND RESULTS: We used a novel allele of β-catenin that preserves β-catenin's cell adhesive...
