Wnt signaling in kidney tubulointerstitium during disease

Abstract

The evolutionary conserved Wnt signaling transduction pathway plays essential roles in a wide array of biologic processes including embryonic development, branching morphogenesis, proliferation and carcinogenesis. Over the past ten years it has become increasingly clear that Wnt signaling also regulates the response of adult organs to disease processes, including kidney disease. This review will focus on the growing literature implicating important roles for Wnt signaling during disease in two separate kidney compartments: the tubular epithelium and the interstitium.
