Genomická selekce v chovu skotu
BARTŮŇKOVÁ, Lenka
This thesis analyses genomic selection with an emphasis on cattle breeding. Genomic selection is starting to become a common element of breeding programmes of livestock animals rearing and this is a new approach to marker-assisted selection (MAS), where instead of identifying individual interconnected loci all information for predictions is obtained from markers, thus making them more accurate. This thesis aims to approach genomic selection, individual methods of selection and their uses, as much as their implementation in cattle rearing. The work devotes a section to applications of genomic selection in Czech Republic. The possible future development of genomic selection is being hinted in the conclusion.

FINE-SCALE RECOMBINATION MAPS OF THE CATTLE GENOME INFERRED BY LINKAGE DISEQUILIBRIUM
MOHAMMADI, Fardokhtsadat
Recombination is a genetic event that occurs during meiosis and leads to the exchange of genetic material between paternal and maternal homologous chromosomes. The intensity of recombination is shown to vary across genomes between and within species, yet the determinants of recombination patterns among populations of the same species are not fully understood. In this thesis, we estimated fine-scale, breed-specific recombination maps of a subset of chromosome 25 of Braunvieh and Fleckvieh cattle for different populations with respect to inbreeding coefficients using the R package LDJump under two assumptions, neutrality and demography. Moreover, we studied the association between recombination rates and genomic features such as SNP count, GC content, and the density and nature of genes. We observed a statistically-significant, weak negative correlation between recombination rates and SNP count, where low recombination rates are accompanied by higher SNP count, and vice versa. More complex demographic scenarios as well as the level of inbreeding should be incorporated in further research using LDJump to address this possible association between SNP count and recombination rates. On the contrary, we observed no such relationship between recombination rates and GC content. We detected a substantial difference in gene density between the lowest and highest SNP-count regions of chromosome 25.

Interaction of selected anthocyanidins with farnesoid X receptor
Jeřábková, Jana ; Pávek, Petr (advisor) ; Martin, Jan (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Jana Jeřábková Supervisor: Doc. PharmDr. Petr Pávek, Ph.D. Title of diploma thesis: Interaction of selected anthocyanidins with farnesoid X receptor Human farnesoid X receptor (FXR) is a member of nuclear receptor superfamily that act as ligand-activated transcription factors. FXR binds to specific regulatory DNA regions and induces expression of many target genes. These regulated genes are involved in bile acid metabolism and transport, maintaining blood lipids, liporoteins and glucose homeostasis and also contribute to maintain intestinal bacterial balance, hepatoprotection and liver regeneration. The interest of recent studies is to test the range of FXR ligands for treatment and prevention of many diseases such as cholestais, cholesterol gallstone disease, steato-hepatitis, dyslipidemia, atherosclerosis, type 2 diabetes mellitus, metabolic syndrome, liver cancer and other forms of cancer such as breast cancer. In this experimental diploma thesis we are focused on testing of potencial ligands of human farnesoid X receptor from the group of natural plant pigments anthocyanidins (cyanidin, delphinidin, malvidin, pelargonidin, peonidin and petunidin) using the human hepatoma cell line...

Genetic variability in sporadic colorectal cancer: Searching for novel risk, prognostic and predictive biomarkers.
Jirásková, Kateřina ; Vodička, Pavel (advisor) ; Machoň, Ondřej (referee) ; Eckschlager, Tomáš (referee)
Colorectal cancer (CRC) is a major public health problem worldwide. Despite improvements in the diagnostic process and advancement in the treatment methods, the prognosis remains poor. To improve survival rates, it is important to identify people with the predisposition for CRC and to detect the potentially curable early stage of the disease. Furthermore, identifying those who would have an adverse clinical outcome associated with a particular chemotherapy would help to avoid redundant chemotherapy burden in patients and contribute to enhanced therapeutic efficacy, while minimizing treatment-related toxicity. The aim of the Thesis was to search for novel promising diagnostic, prognostic and predictive DNA-based biomarkers of sporadic form of CRC. As each patient is genetically unique, these biomarkers would aid clinicians in better diagnosis and/or in the selection of an optimal type of therapy for an individual CRC patient based on their molecular profile. In order to explore this issue, we investigated several candidate genes in healthy individuals as well as in newly diagnosed cancer patients. The major outcomes of this PhD study, which were fully reported in seven publications included in the present Thesis, are 1) The observation of several candidate single nucleotide polymorphisms in microRNA...

Ecophysiological relevance of extreme sensitivity of orchids to nitrates
Figura, Tomáš ; Ponert, Jan (advisor) ; Tylová, Edita (referee)
Many orchid species are seriously endangered at present. Reasons for their disappearing from natural habitats remain often unclear. Orchids depend on mycorrhizal symbiosis in nature, however only little is known about this symbiosis. Seeds of some species do not germinate in vitro, making their cultivation for scientific and rescue purposes impossible. We found that seed germination of one of such reluctant species, Pseudorchis albida, is strongly inhibited by nitrates even at extremely low concentrations. As this species prefers oligotrophic mountain meadows, nitrate-induced inhibition probably take place in natural conditions. Surprisingly, we found similar but slightly weaker inhibitory effect also in typical mesophillic species and even in slightly eutrophic ones. The sensitivity to nitrates correlates with trophy level of species canopy. This inhibitory effect of nitrates could be weakened by application of a range of growth regulators, including auxins, cytokinins and gibberellins, and also by mycorrhizal fungi. The action of nitratereductase is essential for this inhibitory effect of nitrates. Experiments with NO donors, scavengers, and NO quantification are pointing right at NO as compound which perhaps mediates nitrate inhibitory effect. Based on these results, the nitrate inhibitory...

SNP polymorphisms of Y chromosome in the population of african fulani people
Bučková, Jana ; Černý, Viktor (advisor) ; Šimková, Halina (referee)
Markers on the non-recombining region of chromosome Y is a useful tool for study of diversity between populations. SNPs are the most commom polymorphisms in human genome. Mutation rate of SNPs is very low and so they may be used as genetic markers in evolutionary and population studies. We have analyzed 205 unrelated men from 11 Sub-Saharan Fulani's subpopulations. Fulani are an ethnic group of people spread over many countries, mainly in West Africa. Our samples are from Tindangou area, Banfora area (Burkina Faso), Bongor area, Linia area (Chad), Diafarabé area (Mali), Tcheboua area (Cameroon), Banfora area, Diffa area, Zinder area, Ader area and Abalak area (Niger). Using kit Signet Y-SNP Identification Systems and Luminex instrument with LabMAP Luminex Technology we detected particular Y chromosome's SNPs. LabMAP Luminex Technology is universal array platform, which as a probe using fluorescent polystyrene microspheres. We have observed 12 different haplogroups. Haplogroup E, which is typical African haplogroups, is determined with derivated allele in polymorfism M96. We have detected haplogroup E in maximum of 89,3% in the Fulani's subpopulations. In 7,8% we have detected haplogroup R, which is characteristic of populations in the Euroasia. Gene pool of Fulani's population is influenced with a...

Scottish National Party and its position after 1999
Bielawski, Adam ; Říchová, Blanka (advisor) ; Kasáková, Zuzana (referee)
The bachelor's thesis "Scottish National Party and its position after 1999" discusses the development and status of the Scottish National Party since its foundation in 1934 with emphasis on period after the emergence of the Scottish Parliament in 1999. The thesis is focused on the position of the party in political systems of the United Kingdom and Scotland and its efforts to enforce the primary goal of Scottish independence. The basic measures of party's success are election results and participation in decision-making. The author examines the factors influencing the overal image of the party such as ideology, internal situation, party leader, etc. Study of the party documents, such as election manifestos and government programs, is important part of the paper. The last chapter is about independence referendum, which was held in September 2014. Powered by TCPDF (www.tcpdf.org)

Genetic factors affecting course of selected forms of nephrotic syndrome
Šafaříková, Markéta ; Štekrová, Jitka (advisor) ; Král, Jiří (referee)
Nephrotic syndrome (NS) is characterized by proteinuria, hypalbuminemia and edemas. It occurs during first and second glomerulopathies. This disease can be divided into two groups: primary (idiopathic) and secondary. The heredity of the familial nephrotic syndrome is autosomal dominant and autosomal recessive. There are four most important genes that condition the formation of hereditary nephrotic syndrome in adult patienst. These genes are ACTN4, CD2AP, NPHS2 and TRPC6. The gene ACTN4, which encodes protein α-actinin 4, is responsible for the autosomal dominant form of focal segmental glomerulosclerosis (FSGS). FSGS is included in first glomerulopathies. α-Actinin 4 was also researched for some types of carcinomas. There was performed the mutational analysis of the gene ACTN4 on the set of 48 patients with nephrotic syndrome in this diploma thesis. High resolution melting (HRM) analysis and sequencing selected samples were used during this mutation detection. During this process many published and unpublished SNPs and one unpublished candidate mutation that could have causal associations with FSGS were found.
