  1. 1. 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

  3. 2. Herpes Simplex Virus 1 DNA replication and its role in recombination and transcription

    Författare :Ka-Wei Tang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Herpes Simplex Virus 1; DNA replication; DNA recombination; Transcription;

    Sammanfattning : Herpes simplex virus 1 (HSV-1) is one of nine different herpesvirus infecting man. They are all capable of establishing a life-long latent state following the primary infection. HSV-1 as well as other herpesviruses may reactivate from the latent state and give rise to a productive infection with clinical symptoms or asymptomatic shedding. LÄS MER

  4. 3. Crisis in Energy Metabolism - Mitochondrial Defects and a New Disease Entity

    Författare :Gittan Kollberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Energy metabolism; Mitochondrial Disorders; mtDNA; multiple mtDNA deletions; Alpers-Huttenlocher syndrome; POLG1; GYS1; glycogen synthase; point mutation; Polymerase gamma;

    Sammanfattning : Impairment of energy metabolism may be associated with severe implications for affected individuals since all fundamental cell functions are energy-dependent. Disorders of energy metabolism are often genetic and associated with defects in the oxidative phosphorylation in mitochondria. LÄS MER

  5. 4. Molecular mechanisms of mammalian mitochondrial DNA replication and transcription

    Författare :Mina Pellegrini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mitochondrion; DNA polymerase gamma; mtSSB; TWINKLE; DNA replication; transcription; mTERF; MTERF3; MTERF2; nucleoid;

    Sammanfattning : Mitochondria are cytoplasmic organelles in eukaryotic cells, mainly devoted to the synthesis of ATP, through the Oxydative Phospshorylation System (OXPHOS). The organelle has its own genome, the mitochondrial DNA (mtDNA) that encodes for all the RNA components of the mitochondrial translation apparatus (two rRNAs and 22 tRNAs) and for 13 subunits of the OXPHOS complexes.

  7. 5. Apoptosis, cellular division or mitotic catastrophe? Effects of kinase inhibition and DNa damage in lung cancer cells

    Författare :Anna Therése Helén Hemström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Non-small cell lung cancer (NSCLC) cells are generally characterized by a low response to conventional anti-cancer agents, such as DNA-damaging drugs. Treatments that induce DNA damage relies on cellular signalling resulting in the induction of growth arrest and apoptotic cell death. LÄS MER
