RP 1 - Molecular basis of cancer and molecular targets
Can we listen to a crosstalk between cells?
- Mission: To search for proteins regulating tumor development.
- Vision: Contribute to understanding of molecular processes in tumor growth relevant for cancer diagnosis and therapy.
Proteins represent key functional molecules in living organisms. Proteins determine the structure and function of cells, drive metabolic pathways, and participate in signal transduction and regulation of cellular processes. Laboratory of Proteomics studies roles of selected proteins in tumor growth, particularly in proliferation and differentiation of cells. Beside the cellular proteins, we also characterize mechanisms that the cells use for the inter-cellular communication to modify the tumor microenvironment. Proteins released by cells to the extracellular milieu, such as growth factor and cytokines, as well as extracellular vesicles (e.g., exosomes) may carry signals for cell survival and proliferation and they may also participate in regulation of immune response to the tumor. We closely co-operate with Institute of Animal Physiology and Genetics of the Czech Academy of Sciences, where we on a pig model study molecular mechanisms in spontaneous regression of melanoma. Results of our basic research may lead to identification of potential biomarkers for detection of disease development or monitoring the therapeutic response.
