    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente, Jie Ji ... Àlex Bayés
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    Empirical single-cell tracking and cell-fate simulation reveal dual roles of p53 in tumor suppression

    Ann Rancourt, Sachiko Sato, Masahiko S Satoh
    Single-cell tracking and cell-fate simulation suggest that low levels of p53 suppress aneuploid cell formation in unstressed cells and also reveal the dual fate of cells lacking p53 in the presence of p53-proficient cells.

    β-cell intrinsic dynamics rather than gap junction structure dictates subpopulations in the islet functional network

    Jennifer K Briggs, Anne Gresch ... Richard KP Benninger
    The functional network of β-cells in the pancreatic islet, which has been used to identify important subpopulations of β-cells implicated in diabetes progression, is indicative of intrinsic dynamics rather than structural communication, implying islet robustness.

    Functional interrogation of HOXA9 regulome in MLLr leukemia via reporter-based CRISPR/Cas9 screen

    Hao Zhang, Yang Zhang ... Chunliang Li
    The HOXA9 reporter and genetic screens facilitated the functional interrogation of the HOXA9 regulome and advanced our understanding of the molecular regulation network in HOXA9-driven leukemia.

    aPKC-mediated displacement and actomyosin-mediated retention polarize Miranda in Drosophila neuroblasts

    Matthew Robert Hannaford, Anne Ramat ... Jens Januschke
    The actomyosin network and phospho-regulation combine to polarize fate determinants at the Drosophila neuroblast cell cortex.

    ‘Fearful-place’ coding in the amygdala-hippocampal network

    Mi-Seon Kong, Eun Joo Kim ... Jeansok J Kim
    By recording simultaneous spike trains from fear-responsive basal amygdala (BA) and place-responsive dorsal hippocampus (dHPC) neurons in rats foraging for food in a risky predatory situation, a novel BA-dHPC circuit coding mechanism for interfacing danger and place information was revealed.

    An incentive circuit for memory dynamics in the mushroom body of Drosophila melanogaster

    Evripidis Gkanias, Li Yan McCurdy ... Barbara Webb
    Modelling differential roles for identified dopaminergic and output neurons of the fruit fly mushroom bodies, combined with a novel dopaminergic plasticity rule, explains neural and behavioural phenomena in olfactory learning tasks.

    Synaptotagmin 7 docks synaptic vesicles to support facilitation and Doc2α-triggered asynchronous release

    Zhenyong Wu, Grant F Kusick ... Shigeki Watanabe
    The calcium-binding proteins synaptotagmin 7 and Doc2α act sequentially during asynchronous neurotransmitter release.

    Patronin governs minus-end-out orientation of dendritic microtubules to promote dendrite pruning in Drosophila

    Yan Wang, Menglong Rui ... Fengwei Yu
    A minus-end-binding stabilizes minus-end-out microtubules in dendrites, which are required for dendrite-specific pruning during neuronal remodelling.

    Single-amino acid variants reveal evolutionary processes that shape the biogeography of a global SAR11 subclade

    Tom O Delmont, Evan Kiefl ... A Murat Eren
    An in-depth metagenomic analysis of possibly the most abundant and widespread microbial lineage in the surface ocean teases apart evolutionary processes that maintain its genomic heterogeneity and biogeography.
