    Disrupted PGR-B and ESR1 signaling underlies defective decidualization linked to severe preeclampsia

    Tamara Garrido-Gomez, Nerea Castillo-Marco ... Carlos Simon
    The in vivo transcriptomic fingerprint encoding defective decidualization comprises 120 genes associated with an imbalance hormonal signaling in the decidual endometria of women who developed severe preeclampsia.

    Reconciling functional differences in populations of neurons recorded with two-photon imaging and electrophysiology

    Joshua H Siegle, Peter Ledochowitsch ... Saskia EJ de Vries
    Discrepancies between functional responses measured with electrophysiology and calcium imaging can be largely reconciled by considering the spike-to-calcium transfer function, neuronal sampling bias, and cluster merging artifacts during spike sorting.

    Cardiac electrophysiological remodeling associated with enhanced arrhythmia susceptibility in a canine model of elite exercise

    Alexandra Polyák, Leila Topal ... András Varró
    Vigorous endurance training results in prolongation of cardiac repolarization and increased repolarization instability, mild ventricular fibrosis associated with decrease of the transient outward potassium current, and enhanced arrhythmia susceptibility in canine model.

    Molecular function limits divergent protein evolution on planetary timescales

    Mariam M Konaté, Germán Plata ... Dennis Vitkup
    Orthologous proteins that continuously maintain the same molecular function do not usually diverge beyond a certain level of sequence and structural similarity.

    MicroRNA-138 controls hippocampal interneuron function and short-term memory in mice

    Reetu Daswani, Carlotta Gilardi ... Gerhard Schratt
    A new molecular mechanism involving microRNA, which controls synaptic transmission in a specialized type of inhibitory interneurons in the hippocampus and short-term memory in mice, was identified.

    On the pH-dependence of α-synuclein amyloid polymorphism and the role of secondary nucleation in seed-based amyloid propagation

    Lukas Frey, Dhiman Ghosh ... Jason Greenwald
    The amyloid polymorph selection that occurs during α-synuclein aggregation is dictated by environmental conditions, in particular pH, with the largest variety of structures being observed near neutral pH.

    EGF-dependent re-routing of vesicular recycling switches spontaneous phosphorylation suppression to EGFR signaling

    Martin Baumdick, Yannick Brüggemann ... Philippe IH Bastiaens
    Plasticity arising from autocatalytic receptor activation coexists with robustness in ligand responsiveness only by differential endosomal sorting of spontaneous and ligand-activated EGFR as distinct molecular states.
