  1. 11. The exosome and the maintenance of genome integrity

    Författare :Judit Domingo Prim; Neus Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The RNA exosome acts on different RNA substrates and plays important roles in RNA metabolism. The fact that short non-coding RNAs are involved in the DNA damage response led us to investigate whether the exosome plays a role in DNA repair. LÄS MER

  3. 12. Role of latent EBV genes in the induction of genomic instability in Burkitt’s lymphoma

    Författare :Bettina Gruhne; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epidemiological and molecular evidence link Epstein-Barr virus (EBV) infection to a variety of lymphoid and epithelial malignancies but the contribution of the virus to tumorigenesis is unclear. Genomic instability, defined by the establishment of a mutator phenotype and characterized by the occurrence of non-clonal chromosomal aberrations, excessive DNA damage and defects in DNA repair, is the hallmark of malignant transformation.

  4. 13. WRAP53β and scaRNA2 on their journey to repair the DNA

    Författare :Christos Coucoravas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : WRAP53β is a multifunctional protein involved in several cellular processes like Cajal body formation, telomere maintenance and DNA repair. WRAP53β is responsible for targeting factors to specific cellular locations, and its very high affinity for the scaRNAs could implicate these molecules in similar biological functions. LÄS MER

  5. 14. Ion homeostasis in control of stem cell proliferation

    Författare :Shaimaa Abdelhady; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The ion homeostasis is critically maintained in all cells by a combined effort from various ion channels, transporters, pumps, and gap junctions. Ion fluxes are essential in excitable cells as they regulate the excitability of the cells and initiate and propagate action potentials. LÄS MER

  7. 15. Response mechanisms of normal hematopoietic cells and leukemic cells to genotoxic agents and novel therapeutic strategies

    Författare :Andreas Hedblom; Malmö Experimentell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; genotoxic damage; cell cycle; leukemia; heme oxygenase; differentiation;

    Sammanfattning : Hematopoiesis is initiated by a rare population of hematopoietic stem cells (HSC) in the bone marrow (BM). HSCs give rise to red blood cells and white blood cells of myeloid and lymphoid lineages. LÄS MER
