    Roland Houben: Tumor biology of skin cancer

    Summary

    In our research group we are interested in the molecular mechanisms underlying the unrestricted growth of skin cancer cells. One particular focus lies on Merkel cell carcinoma (MCC) a rare but highly aggressive skin cancer with viral etiology. Indeed, the Merkel cell polyomavirus (MCPyV) is found monoclonally integrated in most of the MCC genomes, and MCPyV-positive tumor cell growth is dependent on the expression of viral oncoproteins, termed T antigens. Our group is interested in the molecular pathology of MCC and in particular in the interplay between viral and cellular proteins. Moreover, we are searching for new treatment options for MCC. Further skin cancers we are working on are melanoma and cutaneous T cell lymphoma.
