    1. Chromosomes and Gene Expression

    A synthetic biology approach to probing nucleosome symmetry

    Yuichi Ichikawa et al.
    A novel system for expression of asymmetric nucleosomes in vivo enables mechanistic studies on histone modification readouts in the cell.
    1. Chromosomes and Gene Expression

    Telomere dysfunction cooperates with epigenetic alterations to impair murine embryonic stem cell fate commitment

    Mélanie Criqui et al.
    Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.
    1. Chromosomes and Gene Expression

    Independent manipulation of histone H3 modifications in individual nucleosomes reveals the contributions of sister histones to transcription

    Zhen Zhou et al.
    A yeast genetic model for studying the function of sister histones in chromatin dynamics.
    1. Chromosomes and Gene Expression

    Crosstalk within a functional INO80 complex dimer regulates nucleosome sliding

    Oliver Willhoft et al.
    Regulation of the INO80 chromatin remodelling complex differs from those identified in other chromatin remodellers and involves a C-terminal domain of the Ino80 subunit.
    1. Cancer Biology

    MYC and Twist1 cooperate to drive metastasis by eliciting crosstalk between cancer and innate immunity

    Renumathy Dhanasekaran et al.
    MYC and Twist1 drive metastasis by a novel non-cell-autonomous transcriptional mechanism of eliciting a cytokinome that mediates the crosstalk between cancer cells and macrophages, and its therapeutic blockade inhibits metastasis.

    The conformation of the histone H3 tail inhibits association of the BPTF PHD finger with the nucleosome

    Emma A Morrison et al.
    The BPTF PHD finger is inhibited from binding the methylated H3 tails in the context of the nucleosome due to their robust interaction with the nucleosomal DNA, which can be modulated by additional histone PTMs.
    1. Neuroscience

    Isoform-specific roles for AKT in affective behavior, spatial memory, and extinction related to psychiatric disorders

    Helen Wong et al.
    Murine behavioral testing and biochemical experiments reveal AKT isoform- and sex-dependent mechanisms regulating affective behavior, memory formation, and extinction.
    1. Cell Biology

    Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

    Naemi Luithle et al.
    The INM protein LAP1B, an activator of Torsin ATPases, is a chromatin-binding factor that erroneously persists on mitotic chromatin if Torsin functionality is compromised, inducing chromosome segregation defects and binucleation.

    Convalescent COVID-19 patients are susceptible to endothelial dysfunction due to persistent immune activation

    Florence WJ Chioh et al.
    COVID-19 survivors, who are at risk for vascular complications, would benefit from close monitoring and preventive therapy.

    The ribosomal RNA m5C methyltransferase NSUN-1 modulates healthspan and oogenesis in Caenorhabditis elegans

    Clemens Heissenberger et al.
    In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.
