    The adhesion function of the sodium channel beta subunit (β1) contributes to cardiac action potential propagation

    Rengasayee Veeraraghavan et al.
    Structural and functional investigations identify a structural unit for ephaptic coupling in the heart, and provide the mechanistic basis for a novel strategy for the treatment of arrhythmias.

    Cardiac mitochondrial function depends on BUD23 mediated ribosome programming

    Matthew Baxter et al.
    BUD23 links ribosome function with mitochondrial protein expression and efficient oxidative phosphorylation by promoting selective mRNA translation and is therefore critical to mouse development and postnatal cardiac function.

    Late-life restoration of mitochondrial function reverses cardiac dysfunction in old mice

    Ying Ann Chiao et al.
    Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.

    Instability in NAD+ metabolism leads to impaired cardiac mitochondrial function and communication

    Knut H Lauritzen et al.
    Transgenic mice and cell models provide evidence of a pathophysiological mechanism that connects mtDNA damage to cardiac dysfunction via reduced NAD+ levels and loss of mitochondrial function and communication.

    Late developing cardiac lymphatic vasculature supports adult zebrafish heart function and regeneration

    Michael RM Harrison et al.
    Zebrafish develop cardiac lymphatic vessels along coronary arteries and this vasculature supports scar reduction following severe damage to the myocardium.

    Bid maintains mitochondrial cristae structure and function and protects against cardiac disease in an integrative genomics study

    Christi T Salisbury-Ruf et al.
    An integrative approach, combining genetic mouse and large-scale human genetics studies, was used to reveal a novel role for the Bcl-2 protein Bid in maintenance of mitochondrial function that alters susceptibility to myocardial infarction.

    An adaptation of astronomical image processing enables characterization and functional 3D mapping of individual sites of excitation-contraction coupling in rat cardiac muscle

    Qinghai Tian et al.
    The fusion of astronomy and cellular cardiology reveals the 3D arrangement and the firing reliability of active excitation-contraction coupling sites in beating cardiac myocytes.

    Revised roles of ISL1 in a hES cell-based model of human heart chamber specification

    Roberto Quaranta et al.
    Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.

    Small molecule-mediated refolding and activation of myosin motor function

    Michael B Radke et al.
    The small molecule EMD 57033 is one of a new class of pharmacological chaperones that stabilize, enhance the activity of, and correct stress-induced misfolding of myosin proteins.

    Myocardial NADPH oxidase-4 regulates the physiological response to acute exercise

    Matthew Hancock et al.
    Cardiomyocyte Nox4 is a crucial physiological mediator of Nrf2 activation during acute exercise, triggering an adaptive response that preserves redox balance, mitochondrial and cardiac function to support normal physical exercise.
