    Post-meiotic DNA double-strand breaks occur in Tetrahymena, and require Topoisomerase II and Spo11

    Takahiko Akematsu, Yasuhiro Fukuda ... Josef Loidl
    The first genetic compelling evidence for post-meiotic DNA double-strand breaks and its relation to chromatin remodeling in haploid pronuclei is shown.

    The role of RNA in the maintenance of chromatin domains as revealed by antibody-mediated proximity labelling coupled to mass spectrometry

    Rupam Choudhury, Anuroop Venkateswaran Venkatasubramani ... Axel Imhof
    Proximity biotinylation of the Drosophila centromere suggests a role of RNA helicases, centromeric transcripts, and centromeric R-loops for centromere function.

    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.

    POWERDRESS interacts with HISTONE DEACETYLASE 9 to promote aging in Arabidopsis

    Xiangsong Chen, Li Lu ... Xuehua Zhong
    Genetic and biochemical studies reveal how a histone deacetylase acts together with other chromatin regulators to promote the onset of plant aging.

    Chromosome-specific maturation of the epigenome in the Drosophila male germline

    James T Anderson, Steven Henikoff, Kami Ahmad
    Chromatin profiling of Drosophila testes reveals activation of the transcriptional program of the germline, widespread changes in RNA polymerase progression, and the absence of chromosomal regulation across the X chromosome.

    Chromatin-associated RNA sequencing (ChAR-seq) maps genome-wide RNA-to-DNA contacts

    Jason C Bell, David Jukam ... Aaron F Straight
    ChAR-seq is a massively parallelized de novo RNA mapping assay, which is capable of generating hundreds to thousands of RNA-binding maps with no a priori knowledge of target RNAs.

    ZMYM2 controls human transposable element transcription through distinct co-regulatory complexes

    Danielle J Owen, Elisa Aguilar-Martinez ... Andrew D Sharrocks
    The transcriptional regulator ZMYM2 homes to distinct classes of retrotransposons bound by the TRIM28 and ChAHP chromatin complexes in human cells, which is broadly relevant in the transcriptional regulation field.

    tRNA synthetase counteracts c-Myc to develop functional vasculature

    Yi Shi, Xiaoling Xu ... Xiang-Lei Yang
    In addition to its cytoplasmic role for translation, the seryl-tRNA synthetase also antagonizes the c-Myc transcription factor in the nucleus to transcriptionally repress the growth factor VEGFA and ensure proper development of the vasculature in vertebrates.

    Chromatin mapping identifies BasR, a key regulator of bacteria-triggered production of fungal secondary metabolites

    Juliane Fischer, Sebastian Y Müller ... Axel A Brakhage
    Genome-wide chromatin mapping during bacterial-fungal cocultivation identifies the Myb-like transcription factor BasR as the major regulatory node of bacteria-triggered production of fungal secondary metabolites.

    Local chromatin fiber folding represses transcription and loop extrusion in quiescent cells

    Sarah G Swygert, Dejun Lin ... Toshio Tsukiyama
    Using a yeast model of quiescence, it was demonstrated that dramatic changes in local chromatin fiber folding can occur under physiological conditions to regulate cellular processes.
