    A novel human pluripotent stem cell gene activation system identifies IGFBP2 as a mediator in the production of haematopoietic progenitors in vitro

    Paolo Petazzi, Telma Ventura ... Antonella Fidanza
    A novel tool is used to assess gene function in vitro by targeted endogenous transcriptional activation to unveil novel players in development and disease.

    Bacterial meningitis in the early postnatal mouse studied at single-cell resolution

    Jie Wang, Amir Rattner, Jeremy Nathans
    A model of early postnatal bacterial meningitis in the mouse demonstrates the transcriptome responses of each of the major meningeal cell types and should prove useful in dissecting the pathophysiology of bacterial meningitis in human infants.

    Global hypo-methylation in a proportion of glioblastoma enriched for an astrocytic signature is associated with increased invasion and altered immune landscape

    James Boot, Gabriel Rosser ... Silvia Marino
    A proportion of glioblastoma with global hypo-methylation are enriched for an astrocytic signature and display increased invasion and altered immune landscape.

    Irisin directly stimulates osteoclastogenesis and bone resorption in vitro and in vivo

    Eben G Estell, Phuong T Le ... Clifford J Rosen
    The regulation of bone homeostasis by the exercise-induced myokine irisin is in part potentiated by a direct action on osteoclast differentiation and resorption.

    The transcriptomic response of cells to a drug combination is more than the sum of the responses to the monotherapies

    Jennifer EL Diaz, Mehmet Eren Ahsen ... Gustavo Stolovitzky
    The transcriptomic profiles of the constituent monotherapies of synergistic drug pairs tend to be correlated and result in novel gene expression in the combinations.

    Parent-of-origin effects propagate through networks to shape metabolic traits

    Juan F Macias-Velasco, Celine L St Pierre ... Heather A Lawson
    Non-imprinted genes can contribute to parent-of-origin effects on phenotype through interactions with imprinted genes.

    AP-2α and AP-2β cooperatively function in the craniofacial surface ectoderm to regulate chromatin and gene expression dynamics during facial development

    Eric Van Otterloo, Isaac Milanda ... Trevor Williams
    In addition to a neural crest cell specific role, AP-2α and AP-2ß cooperatively promote craniofacial development through regulating chromatin and gene expression dynamics in the facial surface ectoderm.

    Evolutionary adaptation to juvenile malnutrition impacts adult metabolism and impairs adult fitness in Drosophila

    Berra Erkosar, Cindy Dupuis ... Tadeusz J Kawecki
    Juvenile and adult metabolism are constrained from evolving independently from each other even in a species that lacks developmental continuity between juvenile and adult organs.

    Tau polarizes an aging transcriptional signature to excitatory neurons and glia

    Timothy Wu, Jennifer M Deger ... Joshua M Shulman
    While tau and aging have highly overlapping differential gene expression signatures, they diverge in the affected cell types, with aging having a wide-ranging impact and tau-triggered changes instead polarized to excitatory neurons and glia.

    Polypyrimidine tract-binding proteins are essential for B cell development

    Elisa Monzón-Casanova, Louise S Matheson ... Martin Turner
    The RNA-binding protein polypyrimidine tract-binding protein 1 (PTBP1) is essential for B cell development at the pro-B cell stage where it suppresses S-phase entry and promotes progression through mitosis.
