    Tissue damage drives co-localization of NF-κB, Smad3, and Nrf2 to direct Rev-erb sensitive wound repair in mouse macrophages

    Dawn Z Eichenfield et al.
    Combinatorial signaling leads to transcription factor co-localization at Rev-erb sensitive enhancers, enabling a diversified cellular response to complex stimuli.

    Ongoing repair of migration-coupled DNA damage allows planarian adult stem cells to reach wound sites

    Sounak Sahu et al.
    Adult stem cells acquire increased DNA damage as they migrate to a wound site and require active DNA repair mechanisms for normal migration.

    Microtubule plus-end dynamics link wound repair to the innate immune response

    Clara Taffoni et al.
    Microtubules orchestrate wound repair and innate immune response in the Caenorhabditis elegans epidermis.

    Damage-induced reactive oxygen species regulate vimentin and dynamic collagen-based projections to mediate wound repair

    Danny LeBert et al.
    Live real time imaging and perturbation experiments reveal how vimentin integrates with early damage induced reactive oxygen species to mediate collagen rearrangements and epithelial cell projections during wound repair and regeneration.

    Wilms Tumor 1b defines a wound-specific sheath cell subpopulation associated with notochord repair

    Juan Carlos Lopez-Baez et al.
    Wound-specific notochord sheath cell subpopulations associate with notochord repair and adult vertebrae formation.

    MutSα maintains the mismatch repair capability by inhibiting PCNA unloading

    Yoshitaka Kawasoe et al.
    Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.

    Structural basis for transcription complex disruption by the Mfd translocase

    Jin Young Kang et al.
    Seven distinct cryo-electron microscopy structures delineate the elaborate mechanism for how E. coli Mfd, a transcription repair coupling factor, disassembles the RNA polymerase transcription elongation complex to initiate transcription-coupled repair.

    DAPK interacts with Patronin and the microtubule cytoskeleton in epidermal development and wound repair

    Marian Chuang et al.
    Genetic suppressor screens with C. elegans reveal a novel function for the Death Associated Protein Kinase in regulation of epithelial microtubule dynamics.

    CTCF confers local nucleosome resiliency after DNA replication and during mitosis

    Nick Owens et al.
    In contrast to other transcription factors, CTCF and Esrrb rapidly regain binding after replication and remain bound to their targets during mitosis, preserving local nucleosome organization throughout the cell cycle.

    Stimulation of hair follicle stem cell proliferation through an IL-1 dependent activation of γδT-cells

    Pedro Lee et al.
    Wounded epidermal keratinocytes emit a signal that activates a specialized T-cell in the skin, leading to an increase in hair follicle stem cell numbers that contributes to tissue repair.
