    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm, Matthias Platzer ... Philip Dammann
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    Promoter-specific changes in initiation, elongation, and homeostasis of histone H3 acetylation during CBP/p300 inhibition

    Emily Hsu, Nathan R Zemke, Arnold J Berk
    CBP/p300 acetylation of histone H3 at promoters and enhancers stimulates transcriptional elongation through recruitment of the super-elongation complex and BRD4.

    Effective dynamics of nucleosome configurations at the yeast PHO5 promoter

    Michael Roland Wolff, Andrea Schmid ... Ulrich Gerland
    The integration of multi-nucleosome configuration data with histone turnover and new chromatin accessibility data by systematically investigated 'regulated on-off-slide' models reveals promoter state transitions regulated by just one assembly process.

    A KDM5–Prospero transcriptional axis functions during early neurodevelopment to regulate mushroom body formation

    Hayden AM Hatch, Helen M Belalcazar ... Julie Secombe
    The histone demethylase KDM5 functions in concert with the transcription factor Prospero to regulate a gene expression program that is required for mushroom body neuroanatomical development.

    Human ORC/MCM density is low in active genes and correlates with replication time but does not delimit initiation zones

    Nina Kirstein, Alexander Buschle ... Aloys Schepers
    Replication origins are established throughout the genome with the exception of transcribed genes, and the local chromatin composition likely modulates the density of ORC and MCM as well as origin activation.

    Archaeal chromatin ‘slinkies’ are inherently dynamic complexes with deflected DNA wrapping pathways

    Samuel Bowerman, Jeff Wereszczynski, Karolin Luger
    Archaeal histones compact DNA into nucleosome-like particles of varying sizes that contort sporadically and reorient DNA wrapping.

    Local genetic context shapes the function of a gene regulatory network

    Anna Nagy-Staron, Kathrin Tomasek ... Calin C Guet
    The phenotype of a gene regulatory network depends both qualitatively and quantitatively on the local genetic context of its individual components and cannot necessarily be predicted solely from network's topology.

    Basis of specificity for a conserved and promiscuous chromatin remodeling protein

    Drake A Donovan, Johnathan G Crandall ... Jeffrey N McKnight
    The identification of a novel mechanism of chromatin remodeling, including a conserved remodeler domain and regulatory epitopes, provides targets for the design of therapeutics to modulate transcriptional regulation in cells.

    DDK regulates replication initiation by controlling the multiplicity of Cdc45-GINS binding to Mcm2-7

    Lorraine De Jesús-Kim, Larry J Friedman ... Stephen P Bell
    A multi-step process of helicase activation sensitizes replication initiation to the extent of replicative helicase phosphorylation.

    HAT cofactor TRRAP modulates microtubule dynamics via SP1 signaling to prevent neurodegeneration

    Alicia Tapias, David Lázaro ... Zhao-Qi Wang
    The Trrap-HAT-Sp1 axis operates a conserved transcriptional program to control proper microtubule dynamics in brain homeostasis and prevents neurodegeneration.
