The Role of Cellular Metabolism in Carcinogenesis. Molecular Pathophysiology of Bladder Cancer Chemoresistance
Kripnerová, Michaela ; Kuncová, Jitka (advisor) ; Nevoral, Jan (referee) ; Chovanec, Miroslav (referee)
Therapeutic resistance of tumours represents an important clinical issue. We can classify the therapeutic tumour resistance in two ways. According to the clinical course, tumours can behave either as primary resistant, i.e. from the very beginning not responsive, or they can display a secondary (also called acquired) resistance, whereby an initial clinical response is lost and the tumour develops into chemo-, radio- or immunoresistant disease. An alternative classification distinguishes cell autonomous resistance mechanisms from resistance that relies on complex interactions within the context of tumour microenvironment. From the research perspective, modelling therapeutic resistance frequently involves experimental treatment of sensitive cancer cells and selection of daughter resistant cell lines. The Ph.D. thesis includes derivation of two unique models of urothelial bladder carcinoma therapeutic resistance. The first model involves newly established urothelial carcinoma cell lines BC44 and BC44DoxoR, which resulted from a prolonged doxorubicin exposure of the mother cell line. The daughter chemoresistant cell line exhibits multidrug resistant phenotype, which extends beyond the selecting drug - doxorubicin - to four additional chemotherapeutic drugs (cisplatin, methotrexate, vinblastine, and...

Model Systems in the Study and Teaching of Molecular Biology
Kripnerová, Michaela ; Ehler, Edvard (advisor) ; Němečková, Linda (referee)
Molecular biology and genetics are currently very fast developing disciplines. One of the possibilities how to increase the pupils' interest in studying of molecular biology and genetics, and to support their own curiosity is to use research-based teaching strategies. Although Czech Education tries to correspond with this progress, teaching of molecular biology and genetics is limited not only by financial and material limits but also by a lack of vocational education. The diploma thesis is divided into theoretical and practical part. The theoretical part deals with the position of molecular biology in teaching and model systems in the study and teaching of molecular biology and genetics. The practical part is divided into three chapters. The goal of the first chapter was to present available teaching materials suitable for a teaching at grammar schools, especially with regard to the availability of manuals for practical seminars. The second chapter summarized the results of a questionnaire survey among grammar school teachers, which concerns the position of molecular biology and genetics in teaching. Both of the above-mentioned goals have shown that more needs to be done about the molecular biology of genetics. According to the teachers, students who would like to continue to pursue this...
