  1. 26. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective

    Författare :Robin Öz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-molecule; Protein; NHEJ; Dynamic; DNA repair; HR; Biomolecule interactions; Microscopy; Fluorescence; Nanofluidics;

    Sammanfattning : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. LÄS MER

  2. 27. Ribonucleotide reductase and DNA damage

    Författare :Pelle Håkansson; Lars Thelander; Claes Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ribonucleotide reductase; DNA damage; dNTP pools; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. LÄS MER

  3. 28. DNA double-strand break repair in ascomycetes

    Författare :Jiang Chen; Stefan Åström; Michael Lisby; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Nonhomologous end joining (NHEJ) and homologous recombination (HR) are two pathways for DNA double strand break (DSB) repair. We found that the NHEJ protein Nej1 interacted physically with the HR protein Srs2, which was dependent on phosphorylation of Nej1 by Dun1. Srs2 recruitment to a DSB partly relied on Nej1 and Dun1.

  4. 29. Targeting DNA repair pathways for cancer therapy

    Författare :Saeed Eshtad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Accumulation of genomic mutations is the consequence of failure in DNA repair as well as increased exposure to endogenous/environmental mutagens. DNA repair pathways safeguard the human genome from such mutagens, and thereby suppress the multi-step process of carcinogenesis. LÄS MER

  5. 30. DNA repair by HDR in experimental tumorigenesis

    Författare :Ulrica Westermark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis was to further understand how defects in the homology-directed repair (HDR) pathway affect tumor formation and development. To study proteins involved in HDR is challenging since most of its members are required for cell viability. LÄS MER
