    Tumor suppression in basal keratinocytes via dual non-cell-autonomous functions of a Na,K-ATPase beta subunit

    Julia Hatzold, Filippo Beleggia ... Matthias Hammerschmidt
    A Na,K-ATPase beta subunit can suppress basal cell carcinogenesis either via its osmoregulatory function to avoid hypotonic stress, or by promoting epithelial polarity and adhesiveness of basal keratinocytes from the overlying outer layer.

    β-cell intrinsic dynamics rather than gap junction structure dictates subpopulations in the islet functional network

    Jennifer K Briggs, Anne Gresch ... Richard KP Benninger
    The functional network of β-cells in the pancreatic islet, which has been used to identify important subpopulations of β-cells implicated in diabetes progression, is indicative of intrinsic dynamics rather than structural communication, implying islet robustness.

    Structural and functional characterization of G protein–coupled receptors with deep mutational scanning

    Eric M Jones, Nathan B Lubock ... Sriram Kosuri
    Linking deep mutational scanning with engineered transcriptional reporters in human cell lines establishes a generalizable method for exploring pharmacogenomics, structure, and function across broad classes of drug receptors.

    Integrated β-catenin, BMP, PTEN, and Notch signalling patterns the nephron

    Nils O Lindström, Melanie L Lawrence ... Peter Hohenstein
    The patterning of the nephron is driven by a gradient in the activity of β-catenin and further defined by a network of BMP, PTEN and NOTCH signalling.

    Reversal of β cell de-differentiation by a small molecule inhibitor of the TGFβ pathway

    Barak Blum, Adam N Roose ... Douglas A Melton
    Loss of mature β cell identity in diabetes can be prevented and rescued by small molecule inhibitors of the TGFβ pathway.

    A novel GSK3-regulated APC:Axin interaction regulates Wnt signaling by driving a catalytic cycle of efficient βcatenin destruction

    Mira I Pronobis, Nasser M Rusan, Mark Peifer
    A new dynamic mechanistic model explains how the destruction complex negatively regulates Wnt signaling in development and oncogenesis.

    Innervation modulates the functional connectivity between pancreatic endocrine cells

    Yu Hsuan Carol Yang, Linford JB Briant ... Didier YR Stainier
    Intercellular communication is critical for organ function, and the role of innervation in mediating this communication is of relevance to many fields, including developmental biology, neuroendocrinology, and disease pathophysiology.

    Beta-catenin signaling regulates barrier-specific gene expression in circumventricular organ and ocular vasculatures

    Yanshu Wang, Mark F Sabbagh ... Jeremy Nathans
    Elevating beta-catenin signaling converts endothelial cells in typically fenestrated central nervous system vasculature to a blood-brain barrier (BBB) phenotype and promotes a BBB gene expression program and chromatin landscape.

    A δ-cell subpopulation with a pro-β-cell identity contributes to efficient age-independent recovery in a zebrafish model of diabetes

    Claudio Andrés Carril Pardo, Laura Massoz ... Isabelle Manfroid
    Most regenerated cells after β-cell damage in zebrafish are Insulin+ Somatostatin+ bihormonal cells that are functional and able to restore glucose control.

    Expansion and conversion of human pancreatic ductal cells into insulin-secreting endocrine cells

    Jonghyeob Lee, Takuya Sugiyama ... Seung K Kim
    Cells from the human pancreatic duct can be grown in culture and triggered to become insulin-producing cells, which could potentially be transplanted into patients with diabetes.
