Diploma thesis entitled“Testing of GTPase inhibitors for the study of endocytosis of bionanomaterials” is summarizing the importance of bionanotransporters with a special emphasis on apoferritin, characterizes mechanisms of cellular internalization driven by GTPases and also their inhibitors. The following experimental part shows efficacy of apoferritin fluorescence labelling concluding that Cy2 NHS ester would be suitable for following analyses. Afterwards, expression of TfR1 and SCARA5 receptors was deter-mined and toxicity of dynamine inhibitor dynasore was tested. Internalization inhibition of Cy2 labelled apoferritin by dynasore was tested on five cell lines derived from breast tissue (HBL-100, T-47D, MCF-7, MDA-MB-231 and MDA-MB-468). The same cell lines were used for testing of internalization inhibition of Cy2 APO using dynasore, sodium azide or sucrose. The obtained results confirm internalization inhibition by dynasore and also by dynasore in combination with the other two inhibitors. At the same time, complexity of endocytic mechanisms is emphasized, highlighting need for further testing.
