    Islet vascularization is regulated by primary endothelial cilia via VEGF-A-dependent signaling

    Yan Xiong, M Julia Scerbo ... Per-Olof Berggren
    Primary cilia on endothelial cells are required for VEGF-A/ VEGFR2-dependent signaling, islet vascularization and, consequently, nutrient delivery and insulin disposal.

    P2Y1 purinergic receptor identified as a diabetes target in a small-molecule screen to reverse circadian β-cell failure

    Biliana Marcheva, Benjamin J Weidemann ... Joseph Bass
    A genetically sensitized drug screen identifies a circadian diabetes target and establishes a novel discovery pathway to treat β-cell failure.

    Quantitative H2S-mediated protein sulfhydration reveals metabolic reprogramming during the integrated stress response

    Xing-Huang Gao, Dawid Krokowski ... Maria Hatzoglou
    ATF4, the master regulator of transcription during the Integrated Stress Response (ISR), causes global changes in cysteine sulfhydration of proteins and this event causes cellular metabolic reprogramming.

    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.

    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.

    Time-resolved studies define the nature of toxic IAPP intermediates, providing insight for anti-amyloidosis therapeutics

    Andisheh Abedini, Annette Plesner ... Ann Marie Schmidt
    Toxic IAPP intermediates have some molecular features that are similar to, and others that are distinct from, toxic species reported for other amyloidogenic polypeptides.

    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.

    Reduced synchroneity of intra-islet Ca2+ oscillations in vivo in Robo-deficient β cells

    Melissa T Adams, JaeAnn M Dwulet ... Barak Blum
    Synchronized β cell response to glucose is lost concomitant with loss of islet architecture in Robo-deficient islets of Langerhans in vivo.
