Background: Recent studies have shown that cyclooxygenase-2 (COX-2) inhibitors may participate in the proliferation of cancer cells. Because the cadherin-catenin complex is not only a key component of the adherens junction but also has been suggested to regulate cell proliferation, modulation of these molecules may be a mechanism by which COX-2 activity affects cell proliferation. In this study, we evaluated the effect of a COX-2 inhibitor on the proliferation and expression of E-cadherin-complexes in gastrointestinal cancer cell lines.
