    Colorectal cancer (CRC) is the most common gastrointestinal malignancy. Currently, standard treatment is primary surgery and, depending on the tumor stage, additional chemotherapy. Due to the high recurrence rate vulnerabilities and prognostic markers specific for CRC need to be identified. One of those potential targets is the process of mRNA translation which is highly deregulated in many tumor entities including CRC. Therefore, tumors show different dependencies on translation factors, ribosomal proteins and rRNAs. Our group aims at investigating and exploiting these dependencies to identify new tumor-specific therapeutic options for CRC.

    Research

    Current projects:

    1. Role of eIF3D in regulating MYC translation in CRC

    2. The eIF2/eIF2B complex as potential therapeutic target in CRC

    3. Mechanism of action of the cardiac glycoside cymarine in CRC

    4. Function of the EWS/WT1 fusion protein in desmoplastic small round cell tumor (DSRCT)

    5. Analysis of GNAS mutation as driver in intestinal cancers

    6. Role of mRNA processing factors in transcription-replication conflicts in CRC
