    Evolution of extreme resistance to ionizing radiation via genetic adaptation of DNA repair

    Rose T Byrne et al.
    Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

    Mutant huntingtin impairs PNKP and ATXN3, disrupting DNA repair and transcription

    Rui Gao et al.
    Polyglutamine expansion in mutant huntingtin disrupts a novel transcription-coupled DNA repair complex, providing an undescribed mechanism of neuronal toxicity and degeneration in Huntington's disease.

    Repair of naturally occurring mismatches can induce mutations in flanking DNA

    Jia Chen et al.
    The repair of spontaneous DNA damage can introduce mutators that lead to further genetic changes, which could underlie evolutionary change, disease and aging.

    MicroRNAs down-regulate homologous recombination in the G1 phase of cycling cells to maintain genomic stability

    Young Eun Choi et al.
    MicroRNAs tightly control the cellular level of homologous recombination (HR) factors in the G1 phase, and failure of this control system results in an ectopic increase in HR proteins in G1 cells leading to impaired DNA repair.

    BRCT domains of the DNA damage checkpoint proteins TOPBP1/Rad4 display distinct specificities for phosphopeptide ligands

    Matthew Day et al.
    Structural and biochemical analyses of BRCT domain interactions defines TOPBP1/Rad4 selectivity for phosphorylated motifs, allowing identification of new interactions, and providing insights into assembly of different TOPBP1-scaffolded DNA repair complexes.

    RNase H enables efficient repair of R-loop induced DNA damage

    Jeremy D Amon, Douglas Koshland
    In addition to causing DNA damage, R-loops cause genomic instability by interfering with DNA repair.

    Mismatch repair deficiency endows tumors with a unique mutation signature and sensitivity to DNA double-strand breaks

    Hui Zhao et al.
    A comprehensive catalogue of somatic mutations accumulating in MMR-deficient tumors highlights their relevance in the context of human genetic evolution, for the diagnosis of microsatellite instability and the provision of targeted treatment options.
