  2. 1. Recognition and signaling of DNA double-strand breaks in human cells

    Author : Ismail Hassan Ismail; Göteborgs universitet; []
    Keywords : DNA-PK; DNA double-strand break; DSB; DNA single-strand break; SSB; DNA damage; ionizing radiation; IR; DNA repair; calicheamicin kappa1; ATM; hydrogen peroxide; H2AX; radiotherapy; radiosensitizer; flow cytometry;

    Abstract : DNA double-strand breaks (DSBs) are the most toxic type of DNA damage. Fortunately, our cells have highly conserved pathways that detect and repair DSBs. Defects in DSB signaling and DSB repair pathways result in genomic instability that predisposes for cancer development. READ MORE

  4. 2. Ionising radiation and DNA double strand breaks in human cells : formation, intracellular protection and consequences

    Author : Jonas Nygren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cells; radiation effects; DNA; Cytologi;

    Abstract : .... READ MORE

  5. 3. Characterization of Budding Yeast Nonhomologous End-Joining at DNA Double-Strand Breaks and Telomeres

    Author : Sidney Carter; Stefan Åström; Ed Louis; Stockholms universitet; []
    Keywords : DNA repair; nonhomologous end-joining; double-strand break; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The yeast K. lactis efficiently integrates DNA by illegitimate recombination (IR). IR was completely dependent upon nonhomologous end-joining (NHEJ). In contrast to S. READ MORE

  6. 4. 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

  7. 5. Replication Dynamics in the DNA Damage Response

    Author : Petra Groth; Thomas Helleday; Geroge Iliakis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA replication; homologous recombination; DNA double strand-breaks; ionizing radiation; alkylating agents; NATURAL SCIENCES; NATURVETENSKAP; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Abstract : Faithful DNA replication is essential and the induction of replication stress may have profound effects on genomic integrity. This is demonstrated by the formation of DNA double strand breaks (DSBs), considered to be the most toxic DNA lesions, at stalled replication forks. READ MORE
