#41031 Identification of Predictive Molecular Markers for Cancer Progression, Response to Therapy and Disease Outcome

Our research is focused on studying lung, breast, thyroid and brain tumors. Experimental studies include the identification of changes in genes structure, expression, and corresponding proteins function, which could be used as molecular markers for the prediction of tumor progression, response to therapy and disease outcome. By comprehensive analysis of PI3K/Akt/mTOR key molecules in the postoperative material of different tumor types and by comparative analysis of the complete genome originating from tumor and normal tissue using DNA profiling method, we managed to identify changes in DNA related to carcinogenesis and to define new candidate genes responsible for the cancer progression and resistance to therapy.

New molecular markers were further tested in appropriate cell lines to confirm their role. We gave special attention to the mechanisms of multi-drug resistance, and the potential for its overcoming. Therefore, we developed new multi-drug resistant human and animal cell lines to study the anticancer effects and the mechanisms of a wide range of new natural products, as well as synthetic and semi-synthetic agents. Clinical research includes clinical trials phase II and III, as well as a retrospective study of rare tumors. In theoretical studies, we engaged biophysical analysis in order to define the molecular profile of patients and mathematical models of resistance to chemotherapy. By identifying the molecular changes, defining their contribution to the cancer evolution, by translation into clinical practice and by development of new, more effective drugs, our project should contribute to the achievement of optimal individual therapy for cancer patients.
