21. Gene expression and its physiological control in disease and development : Studies on the human PDGF-B gene and tumour hypoxia
Sammanfattning : Strict control of gene expression is essential during development and in response to physiological stimuli. This thesis describes the functional characterisation of the gene regulatory mechanisms controlling the expression of the potent human growth factor Platelet Derived Growth Factor B gene, in a cell type specific context and in response to low oxygen tension.

22. Behavioural and Neuroendocrine Effects of Stress in Salmonid Fish
Sammanfattning : Stress can affect several behavioural patterns, such as food intake and the general activity level of an animal. The central monoamine neurotransmitters serotonin, dopamine, and norepinephrine are important in the mediation of both behavioural and neuroendocrine stress effects. LÄS MER
23. Comparative Genomics of Obligate and Facultative Intracellular Parasites
Sammanfattning : The α-proteobacteria Rickettsia prowazekii and Bartonella henselae are the causative agents of epidemic typhus and cat scratch disease respectively. Whereas R. prowazekii is an obligate intracellular parasite, B. henselae can live and proliferate both outside and inside the eukaryotic host cell. LÄS MER
24. Patterns and Processes of Molecular Evolution in Rickettsia
Sammanfattning : Species of the genus Rickettsia are obligate intracellular parasites of the a-proteobacterial subdivision. It has been suggested that obligate intracellular bacteria have evolved from free-living bacteria with much larger genome sizes. LÄS MER
25. Structure-aided design of antiviral drugs : Application of the method on HIV-1 protease and SIV reverse transcriptase
Sammanfattning : Many efforts have been made to control the AIDS epidemic. Extensive studies have been done on the biology, biochemistry, and structural biology of HIV in the search for antiviral drugs. The viral-encoded enzymes reverse transcriptase and protease have been main targets for drug design. LÄS MER
