    Rev7 and 53BP1/Crb2 prevent RecQ helicase-dependent hyper-resection of DNA double-strand breaks

    Bryan A Leland et al.
    A single-cell assay reveals that the genetic rewiring that underlies PARP inhibitor resistance drives altered DNA double-strand break end resection pathway choice.

    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.

    Kinesin Kif2C in regulation of DNA double strand break dynamics and repair

    Songli Zhu et al.
    Kinesin Kif2C is recruited to DNA damage sites, modulates the mobility and dynamics of DNA damage foci, and promotes DNA double strand break repair.

    CtIP forms a tetrameric dumbbell-shaped particle which bridges complex DNA end structures for double-strand break repair

    Oliver J Wilkinson et al.
    Structural and biochemical analysis of human CtIP provides new insights into DNA break recognition, binding and bridging during homologous recombination.

    A sharp Pif1-dependent threshold separates DNA double-strand breaks from critically short telomeres

    Jonathan Strecker et al.
    A sharp transition in the fate of DNA ends with telomere sequences is identified, which suggests a boundary between DNA double-strand breaks and telomeres.

    Synergy between SIRT1 and SIRT6 helps recognize DNA breaks and potentiates the DNA damage response and repair in humans and mice

    Fanbiao Meng et al.
    SIRT1 deacetylates SIRT6 at K33 to facilitate DNA double-strand breaks-recognition, subsequent expansion and local chromatin remodeling.

    Resection is responsible for loss of transcription around a double-strand break in Saccharomyces cerevisiae

    Nicola Manfrini et al.
    The conversion of the ends of a double-strand break from double-stranded to single-stranded DNA, which is necessary to initiate homologous recombination, is responsible for loss of transcription and RNA polymerase occupancy around the double-strand break in Saccharomyces cerevisiae.

    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.

    DNA deaminases induce break-associated mutation showers with implication of APOBEC3B and 3A in breast cancer kataegis

    Benjamin JM Taylor et al.
    Enzymes that remove amine groups from cytosine bases in DNA are likely involved in generating the clusters of mutations (kataegis) seen in breast cancer.

    SIRT6 is a DNA double-strand break sensor

    Lior Onn et al.
    Hundreds of proteins are involved in the DNA damage response but only three sensors for DSB were known but now SIRT6 is identified as a fourth DSB sensor.
