Epigenetic regulation of gene expression in cancer progression and HIV-1 latency
Kovářová, Denisa ; Hejnar, Jiří (advisor) ; Černá, Marie (referee) ; Rösel, Daniel (referee)
Epigenetic mechanisms of transcriptional regulation and modulation of gene expression using RNA interference have become a powerfull tool for studying various cellular mechanisms, including tumor progression and viral latency. Advances in expression profiling have provided technology to detect candidate genes implicated in this complex process and bring other possibilities in the diagnosis and treatment of tumor diseases. In this work, I compare the gene expression profiles of v-src-transformed metastatic and nonmetastatic cells using microarray chip technology. Transcription factor homeodomain only protein X (HOPX) was identified as one of the differentially expressed genes. Activity of HOPX gene in several cancer types is usually controlled by promoter methylation. The role HOPX in metastatic formation was assessed by inoculation of cells with modulated expression of HOPX in a syngeneic chicken model system. After HOPX knockdown using shRNA, originally metastatic line showed decreased in vivo metastatic capacity. Further genomic analyses identified a cadre of genes affected by HOPX knockdown. These data demonstrate that HOPX is a metastasis-associated gene and that its knockdown decreases the metastatic activity of v-src-transformed cells through altered gene expression patterns. In the second...
Strong Epistasis in Genetics of Leishmaniasis - Identification of Genes and Mechanisms
Krayem, Imtissal ; Lipoldová, Marie (advisor) ; Černá, Marie (referee) ; Krulová, Magdaléna (referee)
Leishmaniasis, a disease caused by Leishmania parasites, ranks as the leading neglected tropical disease in terms of morbidity and mortality. Genotype of the infected organism is an important factor that influences susceptibility to and manifestations of this disease. To study human disease using mouse models, several strains are required, which could collectively exhibit different human pathophysiology. In the current thesis, we investigated the genetic influence on resting levels of immune cells in mice, because these resting levels could influence susceptibility to many of clinical disorders, including infectious diseases; and we performed a systematic review of the role of host genetics and cytokines in Leishmania infections. Moreover, we employed systems genetics to map genes causing susceptibility to leishmaniasis, and to identify additional mechanisms controlling response to Leishmania parasites. Also, we fine mapped the locus Leishmania major response 15 (Lmr15) in order to functionally characterize its role and to identify novel potential candidate genes regulating the response to L. major. Finally, we show a novel role of guanylate binding proteins 2b and 5 in the resistance to L. major. Strain B10.O20 carrying 3.6% of O20-derived genes on the C57BL/10 genetic background, on chromosomes...
Pilgrimage, countryside and pilgrim
Černá, Marie ; Daniel, Ladislav (advisor) ; Fremlová, Vendula (referee)
The subject of the diploma thesis is the relationship between the artist and the landscape. The thesis focuses mainly on the tradition of pilgrimage and outlines the aspects of the landscape that the artist uses as a pilgrim in his work. The pilgrimage phenomenon is shown here through the works of Czech as well as foreign authors, from the illustrations from the travels to the performances in the landscape. In the didactic part, the tasks focused on the activities in the landscape are outlined, which reflect the perception of the landscape of the secondary school pupils. In the practical part there is a project dealing with the reflection of my travels around the landscape. Keywords Landscape, pilgrim, performance, action art, romanticism

Pathway to inclusion: attitudes towards inclusive education of intellectually disabled children in the Czech Republic
Soo, Suzana ; Šiška, Jan (advisor) ; Černá, Marie (referee)
A small-scale research involving a total of 39 special education teachers and parents was conducted in the city of Sumperk and Rakovnik, in the Czech Republic. Since the implementation of the Equal Education Act in 2004, the numbers of children in segregated special schools remained high and the largest number of children attending these segregated special schools are intellectually disabled. It is believed that the attitudes of special education teachers and parents are important factors in contributing to the current situation in special schools. Powered by TCPDF (
Parental Involvement in the Education of Children with Intellectual disabilities with Regards to the Implementation of Inclusive Education in Primary Schools in Prague
Nabeta Igeme, Alice ; Černá, Marie (advisor) ; Strnadová, Iva (referee)
This research focused on parents' involvement in the education of children with intellectual disabilities in mainstream primary schools. The subjects were parents of children with intellectual disabilities in mainstream primary schools in Prague. Five parents and seven teachers of children with intellectual disabilities were selected for this study. After the selection process, the subjects' views were collected through a semistructured questionnaire. Seven teachers of children with intellectual disabilities whose parents responded to the questionnaire were interviewed by use of a semi- structured interview. The main purpose of the interview was to validate parents' responses to the questionnaire. Data was mainly qualitatively analyzed. Powered by TCPDF (
Prevention of Diabetes Mellitus I. type in childhood
Doudová, Šárka ; Černá, Marie (advisor)
Type 1 diabetes mellitus is among autoimmune disease that primarily affects children and young people. when This disease leads to the destruction of B-cells Pancreatic islets of Langerhans which are responsible for insulin secretion. Its deficiency leads to disturbances metabolism of carbohydrates and other nutrients . The destruction of B- cells occurs gradually and the first clinical symptoms appear only when destruction of a percentage of B- cells of the pancreas . after the outbreak difficulties the patient becomes dependent on exogenous life insulin administration . The incidence of type 1 diabetes mellitus is increasing worldwide and There are significant differences between geographic countries. This suggests that the pathogenesis of the disease have undoubtedly a great influence environmental factors. important role Genetic factors also play a immunological mechanisms. In my work I try to outline the possibilities of prevention as it related prediction type 1 diabetes mellitus . describe primarily genetic , and immunological markers , which can be used to predict genetic risk and to monitor the period before the manifestation of the disease. I mention also the possibilities of primary prevention, which is not currently yet only at the experimental field. Within the secondary Prevention describes...
Reflective practices in Teaching
Chen, Ye ; Šiška, Jan (advisor) ; Černá, Marie (referee)
The aim of this research is to find out if reflective practices exist in Czech schools and whether teachers arc aware of it. Besides, tcachcrs' opinions on reflection as well as conditions that may influence reflection arc examined. For this purpose, a small-scalc questionnaire-based study is earned out with tcachcrs in mainstream and spécial schools. Mixed-methods approach is adopted to collect data from questionnaire, observation and interview, which is then analysed by means of triangulation. Powered by TCPDF (
Assessment of expression markers of HLA class II genes.
Zajacová, Marta ; Černá, Marie (advisor) ; Černý, Jan (referee)
BACKGROUND: HLA molecules play a central role in the immune response. HLA class II are involved in the selection of the T-cell repertoire in the thymus, and in presentation of antigenic peptides to antigen reactive CD4-positive T cells. The HLA class II act as restriction determinants in the presentation of antigens to T lymphocytes and their expression on the cell surface is necessary for triggering the immune responses. Regulated transcription of HLA class II genes is a complex system involving cis-acting sequence elements and trans-acting protein factors. It has been reported that allelic polymorphism exists in the regulatory regions of HLA class II DQA1, DQB1 and DRB1 genes. Most of the polymorphisms appear to be conserved within a haplotype. The hierarchy of sequence homology which exists among the structural genes is not paralleled among their promoter sequences. It is of interest that the most striking discrepancy was found for the DR4 linked alleles, DQB1*0301 and DQB1*0302, which were described as frequent risk factors for a variety of autoimmune diseases. The structural genes of these two alleles are the most closely related, but their regulatory sequences are the most heterogeneous among DQB1 variants. These sequence differences correspond to functional variation: The promoter strength...
