    TPR is required for cytoplasmic chromatin fragment formation during senescence

    Bethany M Bartlett, Yatendra Kumar ... Wendy A Bickmore
    Evidence is provided suggesting that heterochromatin re-organisation during cell senescence can compromise the structural integrity of the nucleus, leading to activation of an inflammatory process.

    Probe-free optical chromatin deformation and measurement of differential mechanical properties in the nucleus

    Benjamin Seelbinder, Susan Wagner ... Moritz Kreysing
    Localized temperature gradients used as a novel method of active micro-theology that is non-invasive and probe-free, to investigate material responses of cell departments such as the different compartments of a nucleus displaying distinct material properties.

    Information content differentiates enhancers from silencers in mouse photoreceptors

    Ryan Z Friedman, David M Granas ... Michael A White
    Silencers and enhancers targeted by a common transcription factor in photoreceptors are distinguished by the number and diversity of binding transcription factor binding sites they contain.

    A unique chromatin profile defines adaptive genomic regions in a fungal plant pathogen

    David E Cook, H Martin Kramer ... Bart P H J Thomma
    Assessment of DNA methylation, histone modifications, and DNA accessibility revealed that physical DNA characteristics are associated with adaptive genome evolution in the broad host range plant pathogenic fungus Verticillium dahliae.

    Condensin I subunit Cap-G is essential for proper gene expression during the maturation of post-mitotic neurons

    Amira Hassan, Pablo Araguas Rodriguez ... Tony D Southall
    The condensin I subunit Cap-G is expressed in post-mitotic neurons and its removal, especially from less mature neurons, results in gene expression changes, reduced survival and behavioural defects in Drosophila.

    Chromatin signature of widespread monoallelic expression

    Anwesha Nag, Virginia Savova ... Alexander A Gimelbrant
    Active and repressive chromatin marks, asymmetrically distributed between alleles, distinguish gene bodies subject to epigenetically controlled monoallelic expression on autosomes in human cells.

    Zygotic pioneer factor activity of Odd-paired/Zic is necessary for late function of the Drosophila segmentation network

    Isabella V Soluri, Lauren M Zumerling ... Shelby A Blythe
    Mechanisms for shaping the chromatin accessibility landscape operate during development to regulate how embryonic patterning information is interpreted at the level of gene regulatory networks.

    How enhancers regulate wavelike gene expression patterns

    Christine Mau, Heike Rudolf ... Ezzat El-Sherif
    An experimental and computational system has been developed to investigate how wavelike gene expression patterns are generated during embryonic development.

    A Brownian ratchet model for DNA loop extrusion by the cohesin complex

    Torahiko L Higashi, Georgii Pobegalov ... Frank Uhlmann
    A structure-based model of the chromosomal cohesin complex, accompanied by molecular-mechanistic simulations, explains cohesin's key role in topologically entrapping DNA, as well as its ability to alternatively extrude DNA loops.
