21. Regulation of Human Mitochondrial DNA Replication and Transcription
Sammanfattning : Mitochondria are organelles in eukaryotic cells, which through oxidative phosphorylation (OXPHOS) produce most of the ATP used to drive cellular processes. The organelle contains its own genetic material, mitochondrial DNA (mtDNA), which encodes 13 key components of the OXPHOS machinery. LÄS MER
22. Studies on antidepressant-mediated regulation of signal transduction
Sammanfattning : Depression affects around 16% of the population at some point in their lives and major depressive disorder is a leading cause of disability worldwide. Depression is caused by an interaction of genetic and environmental factors, but the molecular and cellular mechanisms underlying its pathogenesis are not entirely clear. LÄS MER
23. The Aquaporins - Expression and Regulation of Water Channel Proteins
Sammanfattning : Aquaporins are integral membrane proteins that function as water channels highly specific for water or as aquaglyceroporins permeable to water as well as small solutes such as glycerol and urea. The model plant Arabidopsis thaliana has 35 genes encoding aquaporin proteins. LÄS MER
24. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes
Sammanfattning : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. LÄS MER
25. Regulation of prostaglandin E2 synthesis in human gingival fibroblasts
Sammanfattning : Prostaglandins, especially, prostaglandin E2 (PGE2) play an important role in inflammatory diseases such as rheumatoid arthritis and periodontitis. The aim of the present thesis was to study the production and the regulation of PGE2 with special reference to the key enzymes phospholipase A2 (PLA2) and cyclooxygenase (COX) at the rnRNA level in human gingival fibroblasts.
