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

    Roberto Quaranta, Jakob Fell ... Boris Greber
    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.

    STIM1-dependent peripheral coupling governs the contractility of vascular smooth muscle cells

    Vivek Krishnan, Sher Ali ... Scott Earley
    STIM1 regulates the contractility of blood vessels and blood pressure by organizing membrane contact sites and ion channel activity in vascular smooth muscle cells in a manner that is independent of its canonical function in store-operated Ca2+entry.

    Postsynaptic cell type and synaptic distance do not determine efficiency of monosynaptic rabies virus spread measured at synaptic resolution

    Maribel Patiño, Willian N Lagos ... Edward M Callaway
    Under typical monosynaptic rabies tracing conditions about 40% of first-order presynaptic synapses to cortical neurons are labeled and spread efficiency does not vary depending on the distance of synapses to the cell body, across dendrite types, or starter neuron types.

    Single-nucleus transcriptomics reveal the differentiation trajectories of periosteal skeletal/stem progenitor cells in bone regeneration

    Simon Perrin, Maria Ethel ... Céline Colnot
    A single-nucleus atlas of bone repair uncovers the trajectories of periosteal skeletal stem/progenitor cells in response to fracture and identifies injury-induced fibrogenic cells as intermediate osteochondroprogenitors and key paracrine regulators.

    mTORC1-induced retinal progenitor cell overproliferation leads to accelerated mitotic aging and degeneration of descendent Müller glia

    Soyeon Lim, You-Joung Kim ... Jin Woo Kim
    Comprehensive mouse genetic analyses show, by having mTORC1 constitutively active, a RPC divides and exhausts mitotic capacity faster than neighboring RPCs, and thus produces retinal cells that degenerate with aging-related changes in the mature mouse retina.

    Palatal morphology predicts the paleobiology of early salamanders

    Jia Jia, Guangzhao Li, Ke-Qin Gao
    Salamanders originate as metamorphosed with a biphasic lifestyle as shown by the palate shape and several non-shape features associated with the vomerine teeth, with diverse ecological types displayed in living species achieved in the Early Cretaceous.

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen, Claudio Elgueta ... Carola A Haas
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

    NMNAT promotes glioma growth through regulating post-translational modifications of P53 to inhibit apoptosis

    Jiaqi Liu, Xianzun Tao ... R Grace Zhai
    NMNAT is genetically required for glioma development and promotes glioma growth by allowing a higher tolerance to DNA damage and inhibiting DNA damage-p53-caspase-3 apoptosis signaling pathway by enhancing NAD+-dependent posttranslational modifications (PTMs) poly(ADP-ribosyl)ation (PARylation) and deacetylation of p53.

    Reconfigurations of cortical manifold structure during reward-based motor learning

    Qasem Nick, Daniel J Gale ... Jason Gallivan
    Dimensionality reduction approaches on functional MRI data reveal that human reward-based motor learning emerges from dynamic changes in functional brain network interactions among sensorimotor, attention, and default mode networks.

    An electrophysiological marker of arousal level in humans

    Janna D Lendner, Randolph F Helfrich ... Robert T Knight
    Non-oscillatory brain activity can be used to monitor arousal levels during both NREM and REM sleep as well as under general anesthesia with propofol.
