    The nucleosomal acidic patch relieves auto-inhibition by the ISWI remodeler SNF2h

    Nathan Gamarra et al.
    Auto-inhibition of ISWI-family ATP-dependent chromatin remodelers is relieved by a conserved feature of the nucleosome.

    High levels of histones promote whole-genome-duplications and trigger a Swe1WEE1-dependent phosphorylation of Cdc28CDK1

    Douglas Maya Miles et al.
    Ploidy is stably maintained in Saccharomyces cerevisae by a tight coordination between histone levels and cell cycle events.

    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.

    ketu mutant mice uncover an essential meiotic function for the ancient RNA helicase YTHDC2

    Devanshi Jain et al.
    The mouse gene Ythdc2 exemplifies an evolutionarily ancient family of crucial regulators of the transition from germline stem cell divisions to meiosis.

    Proteomic analysis of the response to cell cycle arrests in human myeloid leukemia cells

    Tony Ly et al.
    Building on previous work (Ly et al., 2014), we show that elutriated cells and arrested cells have similar patterns of DNA content and cyclin expression: however, a large fraction of the proteome changes detected in arrested cells are found to reflect arrest-specific responses rather than physiological cell cycle regulation.

    Stress induced gene expression drives transient DNA methylation changes at adjacent repetitive elements

    David Secco et al.
    Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

    p50-associated COX-2 extragenic RNA (PACER) activates COX-2 gene expression by occluding repressive NF-κB complexes

    Michal Krawczyk, Beverly M Emerson
    A long non-coding RNA removes the transcriptional repressor p50 to regulate recruitment of co-activator p300 and RNA Polymerase II complexes to activate the COX-2 gene in human mammary epithelial cells and macrophages.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo et al.
    The acetylation of histones at specific sites close to DNA can regulate transcription.

    Evolution of histone 2A for chromatin compaction in eukaryotes

    Benjamin R Macadangdang et al.
    The N-terminal domain in histone 2A serves as an evolutionary tool to enable greater chromatin compaction when genome size is disproportionately larger than the nuclear volume across eukaryotes.
