CDH17 and neoplasm: Assuming the particularities of the different cellular models, increasing evidences indicate that the roles of the cadherins in carcinogenesis and tumor progression, do not solely lie on their adhesive function [30-32,39], but also depend on their interaction with other molecules (such as cytoskeletal components, integrins, and growth-factor receptors, among others) and signaling pathways [6,7,40,41].
