1. Advancing Metabolic Engineering through Combination of Systems Biology and Adaptive Evolution
Sammanfattning : Understanding evolutionary strategies of microorganisms may provide opportunities foradvanced strain development with the aim to produce valuable bio-products from renewablebiomass resources. Through evolutionary processes, microorganisms can attain new traitsassociated with genetic changes that may be useful for the construction of improved strains. LÄS MER
2. The venous circulation in teleost fish -responses to exercise, temperature and hypoxia
Sammanfattning : Sandblom, Erik (2007). The venous circulation in teleost fish -Responses to exercise, temperature and hypoxia. Department of Zoology/Zoophysiology, Göteborg University, Box 463, SE-405 30 Göteborg, Sweden. In fish and other vertebrates, venous capacitance changes have important implications on venous return and cardiac filling pressure. LÄS MER
3. Regulation and mechanism of mating-type switching in Kluyveromyces lactis
Sammanfattning : Transposable elements (TEs) have had immense impact on the structure, function and evolution of eukaryotic genomes. The work in this thesis identified Kat1, a novel domesticated DNA transposase of the hAT family in the yeast Kluyveromyces lactis. Kat1 triggers a genome rearrangement that results in a switch of mating type from MATa to MATα. LÄS MER
4. Adhesion-dependent mechanisms regulating mitosis
Sammanfattning : Integrin-mediated cell adhesion is required for normal cell cycle progression during G1-S transition and for the completion of cytokinesis. Cancer cells have ability to grow anchorage-independently, but the underlying mechanisms and the functional significance for cancer development are unclear. LÄS MER
5. Cell fate specification by Ras-mediated cell signalling in C. elegans
Sammanfattning : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. LÄS MER
