    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.

    CRISPR-Cas12a exploits R-loop asymmetry to form double-strand breaks

    Joshua C Cofsky et al.
    The DNA flanks on either side of an R-loop differ in stability, and CRISPR-Cas12 enzymes form double-strand breaks by targeting the more unstable flank with their single DNase active site.

    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.

    Post-meiotic DNA double-strand breaks occur in Tetrahymena, and require Topoisomerase II and Spo11

    Takahiko Akematsu et al.
    The first genetic compelling evidence for post-meiotic DNA double-strand breaks and its relation to chromatin remodeling in haploid pronuclei is shown.

    ZCWPW1 is recruited to recombination hotspots by PRDM9 and is essential for meiotic double strand break repair

    Daniel Wells et al.
    ZCWPW1 has co-evolved with PRDM9, in particular the PRDM9-SET domain, and although not involved in PRDM9's role in positioning recombination events, it is required for PRDM9's role in pairing chromosomes.

    Cisplatin-induced DNA double-strand breaks promote meiotic chromosome synapsis in PRDM9-controlled mouse hybrid sterility

    Liu Wang et al.
    The exogenous DNA DSBs improve meiotic chromosome pairing in mouse inter-subspecific hybrids, thus providing an evidence for a DSB-dependent mechanism of the PRDM9-controlled synapsis failure and infertility.

    ATR/Mec1 prevents lethal meiotic recombination initiation on partially replicated chromosomes in budding yeast

    Hannah G Blitzblau, Andreas Hochwagen
    During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.

    LIN37-DREAM prevents DNA end resection and homologous recombination at DNA double-strand breaks in quiescent cells

    Bo-Ruei Chen et al.
    The LIN37-DREAM complex has a critical role in regulating DNA double-strand break end processing and suppressing aberrant homology-directed repair in quiescent cells.

    Crosstalk between repair pathways elicits double-strand breaks in alkylated DNA and implications for the action of temozolomide

    Robert P Fuchs et al.
    DNA lesions formed by alkylating agents trigger double-strand breaks, in the absence of replication, by the action of MMR and BER at nearby O-alkyl and N-alkyl adducts, respectively.

    Genome-wide mapping of sister chromatid exchange events in single yeast cells using Strand-seq

    Clémence Claussin et al.
    Genome-wide analysis of sister chromatid exchange using single-cell sequencing reveals that most spontaneous sister chromatid exchange events are not due to the repair of double-strand DNA breaks in wild-type yeast cells.
