Background Establishment and maintenance of epithelial cell polarity is regulated in part by signaling from adhesion receptors. Loss of cell polarity is associated with multiple pathologies including the initiation and progression of various cancers. The β1-integrin adhesion receptor plays a role in the regulation of cell polarity; however, the identity of the signaling pathways that modulate β1-integrin function and connect it to the regulation of polarity pathways remains largely unknown.
