In ageing Western societies tumors are becoming the most relevant medical problem. A key characteristic of tumors is deregulated signaling pathways that significantly alter the transcriptional profile of tumor cells. Proteins of the MYC family play a prominent role in this oncogenic reprogramming as transcription factors.
Our vision is to understand the transcriptional changes during carcinogenesis and, in particular, the oncogenic function of Myc to the extent that new pharmaceutical strategies for the fight against cancer can be developed on this basis. To this end, my research group uses genome- and proteome-wide methods to better understand the biology of tumors as well as genetic screens to find potential therapeutic targets of tumor cells. Together with our partners, we have recently developed substances that inhibit the function of Myc. In the next few years, we want to improve these molecules, of the PROTAC substance class, to such an extent that they can be clinically tested and applied.
