Abstract
Beta-catenin regulates cell-cell adhesion by binding to E-cadherin at the cell membrane and, when translocated into the nucleus, mediates signalling by activation of transcription factors such as TCF4. Mutations of the components of the Wnt/beta-catenin pathway are found in many gastrointestinal cancers. Gastrins, including amidated (Gamide) and glycine-extended (Ggly) gastrin(17), stimulate the proliferation of gastrointestinal cancer cells. Gastrins also regulate beta-catenin signalling through multiple pathways which seem to converge on p21-activated kinase 1 (PAK1). In this study, we have investigated the role of PAK1 in the regulation of beta-catenin signalling by gastrins. Here we repo..
