  1. 21. Regulation of Polyamine Analogue-Induced Apoptosis in Human Breast Cancer Cells

    Författare :Martina Holst; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cancer; Animal physiology; Djurfysiologi; Pharmacological sciences; pharmacognosy; pharmacy; onkologi; Cytologi; cancerology; oncology; Cytochrome c; Cytology; Bcl-2; Mitochondrial respiration; Apoptosis; Human breast cancer cells; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Social medicine; Socialmedicin; samhällsmedicin; Mitochondria; Polyamine analogues;

    Sammanfattning : Apoptosis is a defined process for cells to commit suicide through a set of biochemical and morphological cell changes. Activated apoptotic signals converge on the mitochondria, leading to permeabilization of mitochondrial membranes and release of different apoptosis regulatory proteins into the cytosol. LÄS MER

  3. 22. The consequences of DNA lesions for mitochondrial DNA maintenance

    Författare :Josefin M. E. Forslund; Sjoerd Wanrooij; Nasim Sabouri; Erik Johansson; Claes Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; mitochondrial DNA; DNA replication; DNA lesions; DNA polymerase γ; ribonucleotide incorporation; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Eukaryotic cells have their own energy-producing organelles called mitochondria. The energy is stored in the adenosine triphosphate (ATP) molecule and is produced via the oxidative phosphorylation process inside the mitochondria. Thirteen of the essential proteins required for this process are encoded on the mitochondrial DNA (mtDNA). LÄS MER

  4. 23. Organization of mitochondrial gene expression in yeast : Specific features of organellar protein synthesis

    Författare :Kirsten Kehrein; Martin Ott; Thomas A Fox; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; translation; bc1 complex; ribosome; gene expression; Biochemistry; biokemi;

    Sammanfattning : Mitochondria contain their own genetic system, encoding key subunits of the oxidative phosphorylation system. These subunits are expressed by an organelle-specific gene expression machinery. LÄS MER

  5. 24. Mitochondrial Energy Metabolism : Kgd4 is a novel subunit of the α-ketoglutarate dehydrogenase complex

    Författare :Manfred Heublein; Martin Ott; Flavia Fontanesi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; α-ketoglutarate dehydrogenase; Kgd4; Krebs cycle; Biochemistry; biokemi;

    Sammanfattning : Mitochondria are essential organelles of eukaryotic cells and are responsible for their energy metabolism. The citric acid cycle, a chain of redox reactions in the mitochondrial matrix, is a central metabolic hub. LÄS MER

  7. 25. The interactome of the yeast mitochondrial ribosome : Organization of mitochondrial post-transcriptional regulation, membrane protein insertion and quality control

    Författare :Braulio Vargas Möller-Hergt; Martin Ott; Michal Minczuk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitochondrial post-transcriptional regulation; mitochondrial ribosome; membrane protein insertion; mitochondrial quality control; Biochemistry; biokemi;

    Sammanfattning : The proteins found in mitochondria originate from two different genetic systems. Most mitochondrial proteins are synthesized in the cytosol and post-translationally imported into the organelle. However, a small subset of mitochondrial proteins is encoded in an organelle-resident genome. LÄS MER
