    LRRC8A is essential for hypotonicity-, but not for DAMP-induced NLRP3 inflammasome activation

    Jack P Green, Tessa Swanton ... David Brough
    Depletion of LRRC8A provides genetic evidence for the importance of Cl- channels in NLRP3 activation.

    Human Erbb2-induced Erk activity robustly stimulates cycling and functional remodeling of rat and human cardiomyocytes

    Nicholas Strash, Sophia DeLuca ... Nenad Bursac
    Comparative analysis of cardiac mitogenic pathways identified a potent human gene that is effective at driving in vitro cell cycle activation across species and cell culture systems.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu, Damaris N Lorenzo ... Vann Bennett
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    Loss of neurofibromin Ras-GAP activity enhances the formation of cardiac blood islands in murine embryos

    Amanda D Yzaguirre, Arun Padmanabhan ... Jonathan A Epstein
    Ras-GAP activity suppresses the hemogenic potential of the embryonic heart.

    Single-cell transcriptomics defines heterogeneity of epicardial cells and fibroblasts within the infarcted murine heart

    Julia Hesse, Christoph Owenier ... Jürgen Schrader
    The transcriptional landscape of epicardial cells revealed 11 cell populations that differentially expressed early cardiac genes and numerous cardioprotective paracrine factors defining their regenerative potential.

    Myofibroblast senescence promotes arrhythmogenic remodeling in the aged infarcted rabbit heart

    Brett C Baggett, Kevin R Murphy ... Gideon Koren
    Ex vivo, in vitro, and computational modeling studies indicate a persistence of myofibroblast senescence in the infarct border zone with age which can disrupt conduction and promote arrhythmias via senescent myofibroblast-cardiomyocyte coupling.

    Cardiac endothelial cells maintain open chromatin and expression of cardiomyocyte myofibrillar genes

    Nora Yucel, Jessie Axsom ... Zoltan Arany
    Endothelial cells in the heart have transcriptional and epigenetic signatures of cardiomyocytes.

    Therapeutic effects of telomerase in mice with pulmonary fibrosis induced by damage to the lungs and short telomeres

    Juan Manuel Povedano, Paula Martinez ... Maria A Blasco
    Telomerase gene therapy represents a novel effective treatment for pulmonary fibrosis associated with short telomeres by improving pulmonary function, decreasing inflammation and accelerating fiber disappearance in fibrotic lungs.

    The right time for senescence

    Diogo Paramos-de-Carvalho, Antonio Jacinto, Leonor Saúde
    A time-gated model is proposed to reconcile the transient vs. persistent biological activities of cellular senescence, in which 'time' seems to be the main orchestrator of the beneficial vs. detrimental effects of the senescent programme.
