Personalized, cancer-specific networks: Each cancer is different

Proteins play an important role in every cell: They control almost all vital processes in the body. Cancer-related gene mutations can change proteins and affect protein interactions. As a result: A given medication does not provide the same benefit to every cancer patient. A personalized treatment strategy is therefore the long-term goal of the "Personalized Cancer-specific Networks" project funded by DFG-DACH.

For some cancer patients, many standard medications fail in the same way. This is caused by mutations in the genetic material, which change amino acids, the building blocks of proteins. As a consequence, the resulting proteins can deviate so starkly from standard that this may disturb an interaction between usual interaction partners. In this way, medication normally modeled on the respective interaction partner in order to affect a protein interaction will become less effective or even ineffective. This makes it all the more important for physicians to test in advance whether a specific medication will be effective or not for a certain patient.

As part of the "Personalized Cancer-specific Networks" project, the Technical University of Munich, the Innsbruck Medical University, and ETH Zurich are working on the common goal of creating individual cancer prognoses using a systematic approach. Because the individual genetic material regulates how proteins function, it is essential to identify individual differences and use these for the therapy. Mutations in the genetic material, the resulting protein characteristics, and the respective disease symptoms (cancer) should therefore be considered together. This creates causal relationships that make it possible to develop a therapy approach tailored to the patient. In concrete terms, protein mutations are analyzed using bioinformatic methods, which allows the interactions of patient-specific protein variations to be simulated with a computer. The goal here is to identify those mutations that have an effect with the patient's variant, i.e. to create a clinical picture (candidate model). Researchers obtain information from the patient's genetic material and existing proteins to work out such candidate models. The respective models are then compared and validated experimentally using synthesized protein complexes and patient samples.
