Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) is an immunoglobulin superfamily member with a diversity of extracellular ligands that is implicated in the initiation and progression of a variety of malignancies. We sought to characterize the effects of CEACAM6 crosslinking on pancreatic adenocarcinoma cellular interaction with the extracellular matrix (ECM) components fibronectin and vitronectin. Antibody-mediated CEACAM6 crosslinking was performed and the ability of BxPC3 cells, which inherently overexpress CEACAM6, to adhere to fibronectin and vitronectin was quantified. The roles of the archetypal fibronectin (α₅β₁ integrin) and vitronectin (α_vβ₃ integrin) receptors were determined. The effects of c-Src inhibition were investigated using the Src family kinase inhibitor 4-amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyrimidine (PP2) and c-Src specific RNA interference. CEACAM6 crosslinking initiates c-Src-dependent cross-talk between CEACAM6 and α_vβ₃ integrin, leading to increased ECM component adhesion. CEACAM6-mediated signaling events may contribute to the invasive and metastatic potential of pancreatic adenocarcinoma cells by promoting their interaction with ECM components.
