16. Cell signaling by Rho and Miro GTPases : Studies of Rho GTPases in Cytoskeletal Reorganizations and of Miro GTPases in Mitochondrial Dynamics
Sammanfattning : The Ras superfamily of GTPases embraces six major branches of proteins: the Ras, Rab, Ran, Arf, Rho and Miro subfamilies. The majority of GTPases function as binary switches that cycle between active GTP-bound and inactive GDP-bound states. This thesis will focus primarily on the biological functions of the Rho and Miro proteins. LÄS MER
17. Life without mitochondrial DNA : studies of transgenic mice
Sammanfattning : Mitochondrial DNA (mtDNA) is a closed circular DNA genome that resides in the mitochondrial network. Mutations of mtDNA cause spontaneous and hereditary disorders known as mitochondrial diseases. Mitochondrial transcription factor A (Tfam) is a key factor for transcription of mtDNA in vitro. LÄS MER
18. Training-induced increase in mitochondrial biogenesis
Sammanfattning : Endurance training leads to an improved ability of muscle to utilize oxygen. This is related to an increased density and function of mitochondria. LÄS MER
19. Initiation of Mammalian Mitochondrial DNA Replication
Sammanfattning : Mitochondria produce most of the adenosine triphosphate required in a eukaryotic cell and they contain their own genome. The mitochondrial DNA (mtDNA) is a double stranded circular molecule that codes for proteins required for cellular respiration and RNA molecules involved in translation of these proteins. LÄS MER
20. Molecular mechanisms of mitochondrial DNA replication
Sammanfattning : Mitochondria are the energy producing organelles of eukaryotic cells. The organelle has its own genome, the mitochondrial DNA (mtDNA) that encodes 13 subunits of the respiratory chain (RC) complexes, two rRNAs and 22 tRNAs. LÄS MER
