Wingless/Notch crosstalk in Drosophila melanogaster
Hajšmanová, Hana ; Mašek, Jan (advisor) ; Macůrková, Marie (referee)
Fundamental for the existence of multicellular organisms is the presence signalling pathways, complex biochemical cascades, allowing reciprocal communication amongst the cells. Both Notch and Wnt pathways are crucial for embryonic development and their deregulation leads to many severe diseases. Decades of research, largely based on model organism D. melanogaster, showed that components of these pathways do not function strictly separately but on contrary interact with each other (crosstalk). This phenomenon is explored only to a lesser extent in mammals. The aim of this thesis is to recapitulate existing findings of Wnt/ Notch crosstalk in D. melanogaster and outline where crosstalk could play a role in mammals.
Genetic screening for the dominant suppressors of adgf-a mutant phenotype in Drosophila
HARTMANN, David
Extracellular adenosine is an important signaling molecule in various physiological processes. When not regulated properly it can cause various pathologies such as Severe Combined Immunodeficiency. To study the effects of increased extracellular adenosine level a Drosophila model has been established. This model is based on mutation in the main adenosine deaminase gene in Drosophila (ADGF-A, Adenosine Deaminase-related Growth Factor A). This work is a consequence of large screening for the suppressors of adgf-a mutant phenotype and presents a more detailed study of 3 previously identified regions containing dominant suppressors.
