    PreBötzinger complex neurons drive respiratory modulation of blood pressure and heart rate

    Clément Menuet et al.
    The PreBötzinger complex, which contains neurons that are the kernel for inspiratory rhythm generation, also contains sympathoexcitatory and parasympathoinhibitory neurons that drive respiratory-phase oscillations in blood pressure and heart rate.

    A calcium transport mechanism for atrial fibrillation in Tbx5-mutant mice

    Wenli Dai et al.
    TBX5-loss associated cardiomyocyte ectopy and atrial fibrillation is prevented by augmentation of SERCA2 activity, establishing a mechanism underlying the genetic basis for a Ca2+-dependent pathway for AF risk.

    KCNE1 tunes the sensitivity of KV7.1 to polyunsaturated fatty acids by moving turret residues close to the binding site

    Johan E Larsson et al.
    An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.

    KPNB1 mediates PER/CRY nuclear translocation and circadian clock function

    Yool Lee et al.
    KPNB1 regulates rhythmic spatio-temporal nuclear import of the PER/CRY complex and is required for negative feedback repression in mammalian and fly clock function.

    Accurate timekeeping is controlled by a cycling activator in Arabidopsis

    Polly Yingshan Hsu et al.
    The circadian clock in the model plant organism Arabidopsis thaliana is best described as a highly connected network made up of clock-regulated activators and repressors of transcription, rather than two coupled, repressor-based feedback loops.

    Development, calibration, and validation of a novel human ventricular myocyte model in health, disease, and drug block

    Jakub Tomek et al.
    A computer model of human cardiomyocyte was produced and validated on independent datasets, overcoming shortcomings of its predecessors, also yielding broadly relevant insights and results on major ionic currents.
