NCT-Junior-Research Group Tumor Invasion and Metastasis

The focus of the Tumor Invasion and Metastasis (TIM) junior research group lies on the motile behavior of tumor cells in the context of radiation therapy. The mechanisms of migration and invasion of tumor cells within tissues as well as tumor cell metastasis are investigated.

Understanding cell motility and metastasis in radiation oncology

Current studies suggest a connection of radiation therapy and the motile capacity of tumor cells. Unclear are the mechanistic links and the underlying cellular and molecular processes. Unraveling these fundamental mechanisms in the context of radiation therapy is the primary aim of the research group and key to the development of novel therapeutic approaches.

Another major focus lies on the identification of specific tumor cell characteristics – so called biomarkers – as predictors of tumor cell escape from the primary site and the formation of distant metastasis. Further steps will aim at visualization and molecular targeting of invading and metastasizing tumor cells on top of sensitization to radiation therapy.
