    Broad-scale variation in human genetic diversity levels is predicted by purifying selection on coding and non-coding elements

    David A Murphy, Eyal Elyashiv ... Guy Sella
    Background selection is shown to be the dominant mode of linked selection in humans, with marked effects on diversity levels throughout autosomes.

    Dedicated chaperones coordinate co-translational regulation of ribosomal protein production with ribosome assembly to preserve proteostasis

    Benjamin Pillet, Alfonso Méndez-Godoy ... Dieter Kressler
    A novel co-translational mechanism continuously adjusts the expression levels of ribosomal proteins Rpl3 and Rpl4 to their consumption during ribosome synthesis by regulating the abundance of their mRNAs.

    Sex-specific splicing occurs genome-wide during early Drosophila embryogenesis

    Mukulika Ray, Ashley Mae Conard ... Erica Larschan
    Combining computational and experimental approaches reveals that the loss of a maternal transcription factor influences sex-biased differential splicing in the early zygotic transcriptome at genes that are critical for normal developmental processes.

    Topological stress triggers persistent DNA lesions in ribosomal DNA with ensuing formation of PML-nucleolar compartment

    Alexandra Urbancokova, Terezie Hornofova ... Pavla Vasicova
    Chemotherapeutics altering DNA topology evoke RNA polymerase I inhibition, rDNA damage and consequent formation of PNAs that segregate persistent rDNA lesions from the active nucleolus, with implications for rDNA maintenance and design of new cancer treatment strategies targeting rDNA repair.

    A prion accelerates proliferation at the expense of lifespan

    David M Garcia, Edgar A Campbell ... Daniel F Jarosz
    In its capacity to switch into a heritable, prionogenic form, a conserved RNA-modifying enzyme epigenetically alters fundamental growth, aging, and protein synthesis properties of eukaryotic cells.

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman, Sviatlana Shashkova ... Mark C Leake
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.

    An in silico FSHD muscle fiber for modeling DUX4 dynamics and predicting the impact of therapy

    Matthew V Cowley, Johanna Pruller ... Christopher RS Banerji
    Mathematical and experimental characterization of DUX4 expression dynamics in facioscapulohumeral muscular dystrophy muscle fibers, provides insights into pathology and open-source tools for in silico investigation of anti-DUX4 therapy.

    Pleiotropic effects of trisomy and pharmacologic modulation on structural, functional, molecular, and genetic systems in a Down syndrome mouse model

    Sergi Llambrich, Birger Tielemans ... Greetje Vande Velde
    Ts65dn mice exhibit structural, functional, molecular, and genetic alterations that are modulated but unrecovered by prenatal chronic GTE-EGCG, highlighting the importance of holistic studies to understand complex disorders and treatments.

    Improved inference of population histories by integrating genomic and epigenomic data

    Thibaut Sellinger, Frank Johannes, Aurélien Tellier
    The developed statistical method paves the way for next generation demographic and selection inference by combining information from several heritable genomic and epigenomic markers.
