Genetically encoded biosensors of cellular tension and their use in cellular biology
Pelantová, Markéta ; Rösel, Daniel (advisor) ; Lánský, Zdeněk (referee)
1 Abstract and key words Mechanical forces have great impact on the life of cells. They influence cell proliferation, migration or differentiation and defects in cellular mechanosensing were reported to be the cause of various diseases, such as deafness, atherosclerosis or cancer. However, mechanisms of mechanical sensing are not thoroughly examined and not many tools for doing such research are available. Genetically encoded FRET-based biosensors are one of the existing methods for studying transfer of mechanical signal in cells. It is a non-invasive method allowing to observe changes in mechanical tension across proteins in living cells. In this thesis, different types of existing genetically encoded FRET-based tension biosensors are introduced together with the process of their development and knowledge gained by their use in research. Key words: mechanical force, mechanosensing, FRET, tension sensor, biosensor development
