Tumor Metastasis and the Proteolytic Network

Most cancer patients succumb to metastasis and not to the primary tumor. In order to develop new strategies for the treatment of metastatic disease it is mandatory to obtain more knowledge about the underlying mechanisms of metastasis biology.

The research group led by the biologist Prof. Achim Krüger investigates tumor-host interactions during metastasis. Specifically, this group analyses the role of endogenous proteinases and proteinase inhibitors, which are major determinants of the homeostasis in the microenvironment of tumors or future sites of metastasis in organs distant from the primary tumor. Both, proteinases and proteinase inhibitors enable tumor cells to migrate and invade through tissue and to disseminate to distant organs or increase the susceptibility of the target organs of metastasis to tumor cells. These molecules also emerged to decisively regulate or induce signal transduction in tumor and normal cells, which, in turn, determines the metastatic potential of tumor cells or the interaction of healthy tissue with invading cells.

The results of this research contribute to the understanding of the complex processes of metastasis formation and are the basis of new treatment approaches.
