    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.

    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.

    Covalent linkage of the DNA repair template to the CRISPR-Cas9 nuclease enhances homology-directed repair

    Natasa Savic et al.
    Linking the DNA repair template to the Cas9 ribonucleoprotein complex enhances homology-directed repair of the induced DNA double strand break.

    SETD2 is required for DNA double-strand break repair and activation of the p53-mediated checkpoint

    Sílvia Carvalho et al.
    The involvement of SETD2 in an important DNA repair pathway could explain the high frequency of SETD2 mutations in several cancers and may provide an alternative mechanism to evade the p53-mediated checkpoint.
