The E-cadherin-catenin complex: pivotal role in suppression of tumor malignancy
For several years this research group has been focusing on the invasion and tumor suppressor roles of the cell-cell adhesion molecule E-cadherin, and on associated or related proteins. In a majority of aggressive epithelial tumor cells, the pivotal E-cadherin gene either bears inactivating mutations or is transcriptionally silenced. A third and intriguing possibility is the dysregulation of cadherin functionality at the level of its cytoplasmic anchoring via a variety of catenins to the cytoskeleton.
Numerous new structural and regulatory proteins were recently localized in the cell adhesion junctions, often in a cell-type and tissue-specific manner. Several of these proteins can function in both specific adhesion and signaling. Notable examples are -protocadherins and armadillo proteins such as β-catenin, p120ctn and plakophilins. We aim at a thorough understanding and
Advanced localization of proteins of interest in tissues like the intestine meaningful interpretation of the physiological functions and mutual interactions of these proteins, under both normal and pathological conditions.
Moreover, we are scrutinizing recently discovered novel genes and proteins that appear to have an oncogenic or invasion stimulatory role.
