Epigenetic Inactivation of Wnt Inhibitory Factor-1 Plays an Important Role in Bladder Cancer through Aberrant Canonical Wnt/β-Catenin Signaling Pathway

Abstract

This is the first report showing that CpG hypermethylation of the Wif-1 promoter is a frequent event in bladder tumor and may contribute to pathogenesis of bladder cancer through aberrant canonical Wnt/beta-catenin signaling pathway. The present study elucidates novel pathways that are involved in the pathogenesis of bladder cancer.
