  2. 1. Silencing and DNA double-strand break repair in budding yeast

    Author : Andreas Kegel; Stefan Åström; Stephan Marcand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silencing; Reb1; DSB; NHEJ; Nej1; illegitimate recombination; yeast; Developmental biology; Utvecklingsbiologi;

    Abstract : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. READ MORE

  4. 2. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks

    Author : Karin Karlsson; Bo Stenerlöw; Jörgen Carlsson; Thomas Helleday; Uppsala universitet; []
    Keywords : Molecular biology; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionising radiation; high-LET; heat-labile sites; PFGE; Molekylärbiologi;

    Abstract : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. READ MORE

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

    Author : Robin Öz; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Radiation response in human cells : DNA damage formation, repair and signaling

    Author : Ann-Sofie Gustafsson; Bo Stenerlöw; Andrzej Wojcik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

  7. 5. Induction and repair of clustered DNA damage sites after exposure to ionizing radiation

    Author : Andris Abramenkovs; Bo Stenerlöw; Peter O'Neill; Uppsala universitet; []
    Keywords : NHEJ; DSB repair; clustered DNA damage; DNA repair; DNA-PKcs; HSCS; Ra-223; ionizing radiation; Medicinsk vetenskap; Medical Science;

    Abstract : The mechanisms that maintain genomic stability safeguard cells from constant DNA damage produced by endogenous and external stressors. Therefore, this thesis aimed to specifically address questions regarding the requirement and involvement of DNA repair proteins in the repair of various types of radiation-induced DNA damage.
