β-Catenin Causes Renal Dysplasia via Upregulation of Tgfβ2 and Dkk1

Abstract excerpt

Renal dysplasia, defined by defective ureteric branching morphogenesis and nephrogenesis, is the major cause of renal failure in infants and children. Here, we define a pathogenic role for a β-catenin-activated genetic pathway in murine renal dysplasia. Stabilization of β-catenin in the ureteric cell lineage before the onset of kidney development increased β-catenin levels and caused renal aplasia or severe...
