Vytvoření a charakterizace transgenních linií drozofil manifestující neurodegenerativní onemocnění spinocerebelární ataxi typu 1 (SCA1)
 JIČÍNSKÁ, Veronika
The aim of this thesis was to generate and characterize transgenic lines of Drosophila melanogaster manifesting spinocerebellar ataxia type 1 (SCA1), using GAL4/UAS system. Specific driver lines were used to express ataxin gene in pan neuronal, eye and motor neurons. Adult males from different crosses expressing abnormal ataxin gene with parallel controls aged 5 day and 30 day were used for all experiments. The effects of such expression on mobility, longevity and neurodegenerative changes in the brain was studied. Moreover, specific techniques such are RT-PCR, and western blotting were used to test expression of specific genes and to quantify level of specific proteins. Neurodegenerative changes in transgenic lines were documented using confocal microscopy. The expression of specific genes such as ataxin and matrix metalloproteinase 1 and 2 (dMMP1, dMMP2) was studied in all used fly lines. The results showed that gene expression of hAtXN1 was higher in lines manifesting SCA1 compared to controls. However, the trend of MMP expression was not completely clear and will be the subject of future research.
