Prediction of Treatment Effect in Solid Tumors
Houfková, Kateřina ; Pešta, Martin (advisor) ; Fiala, Ondřej (referee) ; Šána, Jiří (referee)
Current research of treatment of oncological diseases is focused on the identification of changes that occur in the process of carcinogenesis and on the search for therapeutics that would make it possible to eliminate the manifestation of these changes. Early diagnosis, estimating prognosis, monitoring of the course of the disease and prediction of the effect of treatment are increasingly associated with the determination of appropriate biomarkers. The assessment of predictive biomarkers should become an integral part of treatment decisions and, as a result, help patients to prolong life and improve quality of life. The aim of my thesis was to find prognostic and predictive biomarkers for more effective treatment of cancer patients. In cooperation with a number of clinical departments of the University Hospital in Pilsen, I focused on the research of these biomarkers at the Department of Biology, especially in non-small cell lung cancer, endometrial cancer, colorectal cancer, liver metastases of colorectal cancer, clear cell renal cell carcinoma and sarcomas. We focused on the research of molecules that are involved in the process of carcinogenesis and whose levels in body fluids or directly in tumor tissue would be able to predict further disease development or therapeutic response.

Regulation of diapause in the western corn rootworm (\kur{Diabrotica virgifera virgifera} LeConte)
HOUFKOVÁ, Kateřina
The thesis aims to optimize the methods of laboratory culture and to fill in the gaps in knowledge of D. virgifera virgifera ecophysiology. The experiments on embryology and development proved that the diapause of D. virgifera virgifera is of obligatory type and can be terminated by exposure to long-day conditions (20:4; photo : scotophase) and constant temperature of 25 °C. Approximately 10% of eggs completed the development to adults within 4 months. Besides numerous other environmental conditions that are discussed, temperature seems to be a key factor influencing longevity in this pest. Higher temperature of 25 °C prolonged survival by more than 20 days in 2015, compared to 22 °C in 2014.
Selected ecophysiological characteristics of the new invasive pests in agriculture.
HOUFKOVÁ, Kateřina
The aim of this thesis was to gather and review information on biology and ecophysiology of four invasive species that are considered to be important pests in agriculture. Following species were chosen for the review: Tuta absoluta, Epitrix spp., Ostrinia nubilalis and Diabrotica virgifera virgifera. Experimental part of the thesis consists of ecophysiological and survival experiments conducted on one of the selected species ? Diabrotica virgifera virgifera. The influence of temperature and photoperiod on egg diapause termination was tested in the laboratory. A comparison of adulta survival on three different diets is also included.
