    Distinct skeletal stem cell types orchestrate long bone skeletogenesis

    Thomas H Ambrosi, Rahul Sinha ... Charles KF Chan
    Functional and molecular analyses of two distinct skeletal stem cell populations establish the important role of stem cell diversity that provides a framework for novel investigations into skeletal biology.

    Respiratory and intestinal epithelial cells exhibit differential susceptibility and innate immune responses to contemporary EV-D68 isolates

    Megan Culler Freeman, Alexandra I Wells ... Carolyn B Coyne
    Parallel studies in primary human airway cells and stem cell-derived enteroids show that Enterovirus D-68 differentially infects and induces innate immune signaling in the respiratory and intestinal epithelium.

    7,8-Dihydroxyflavone modulates bone formation and resorption and ameliorates ovariectomy-induced osteoporosis

    Fan Xue, Zhenlei Zhao ... Ying Zhang
    In vitro and in vivo studies highlight the dual regulatory effects that 7,8-dihydroxyflavone exerts on bone formation and resorption.

    Establishment of H3K9me3-dependent heterochromatin during embryogenesis in Drosophila miranda

    Kevin H-C Wei, Carolus Chan, Doris Bachtrog
    Heterochromatin is established at nucleation sites associated with open chromatin and RNA transcripts and matures into stable domains if they are found near transposable elements targeted by maternally deposited piRNAs.

    An epigenetic switch regulates the ontogeny of AXL-positive/EGFR-TKi-resistant cells by modulating miR-335 expression

    Polona Safaric Tepes, Debjani Pal ... Raffaella Sordella
    Erlotinib-resistant AXL overexpressing cells are present in therapy-naive tumors, and expression of AXL in these cells is regulated through a stochastic mechanism centered on the epigenetic regulation of miR-335.

    Reconciling functional differences in populations of neurons recorded with two-photon imaging and electrophysiology

    Joshua H Siegle, Peter Ledochowitsch ... Saskia EJ de Vries
    Discrepancies between functional responses measured with electrophysiology and calcium imaging can be largely reconciled by considering the spike-to-calcium transfer function, neuronal sampling bias, and cluster merging artifacts during spike sorting.

    Action potential-coupled Rho GTPase signaling drives presynaptic plasticity

    Shataakshi Dube O'Neil, Bence Rácz ... Scott H Soderling
    Proteomic and genetic analysis discovers a new cytoskeletal mechanism of presynaptic short-term plasticity common across neuronal cell types.
    1. Evolutionary Biology

    Contingency and chance erase necessity in the experimental evolution of ancestral proteins

    Victoria Cochran Xie, Jinyue Pu ... Bryan C Dickinson
    Replicating experimental evolution from ancestral proteins shows that historical contingency steadily overwhelms chance and necessity as the primary cause of evolutionary variation in molecular sequences on long phylogenetic timescales.

    Ct threshold values, a proxy for viral load in community SARS-CoV-2 cases, demonstrate wide variation across populations and over time

    A Sarah Walker, Emma Pritchard ... COVID-19 Infection Survey team
    Wide variation in cycle threshold (Ct) values from SARS-CoV-2 RT-PCR tests over calendar time offers the potential for their broader use in public testing programmes as an ‘early-warning’ system for shifts in infectious load and hence transmission.

    Pak1 and PP2A antagonize aPKC function to support cortical tension induced by the Crumbs-Yurt complex

    Cornelia Biehler, Katheryn E Rothenberg ... Patrick Laprise
    Cell biology analyses in Drosophila epithelial tissues reveal novel mechanisms connecting epithelial polarity proteins with Myosin-dependent cell contractility.
