    Robo2 acts in trans to inhibit Slit-Robo1 repulsion in pre-crossing commissural axons

    Timothy A Evans et al.
    The Roundabout2 receptor acts non-autonomously to promote commissural axons to cross the midline by antagonizing Slit-dependent axon repulsion.

    The mammalian lectin galectin-8 induces RANKL expression, osteoclastogenesis, and bone mass reduction in mice

    Yaron Vinik et al.
    The secreted sugar-binding protein galectin-8 causes osteoblasts to secrete factors that promote the differentiation of bone marrow cells into osteoclasts; targeting this protein could therefore potentially help treat diseases associated with excessive bone loss.

    The transcription factor Pitx2 positions the embryonic axis and regulates twinning

    Angela Torlopp et al.
    In higher vertebrates, the position of the embryonic axis (the location at which gastrulation starts) is determined by the transcription factor Pitx2, which suggests that the mechanisms of this process, and hence those that regulate twinning, are related to those that set up the left–right axis.

    Genome-wide interrogation of extracellular vesicle biology using barcoded miRNAs

    Albert Lu et al.
    A screen using artificially barcoded, exosomal microRNAs, paired with CRISPR guide RNAs, helped identify new players in multivesicular endosome exocytosis and a role for Wnt signaling.

    Synapse maintenance is impacted by ATAT-2 tubulin acetyltransferase activity and the RPM-1 signaling hub

    Melissa A Borgen et al.
    Genetic, developmental and pharmacological analysis in Caenorhabditis elegans demonstrate that ATAT-2 tubulin acetyltransferase activity regulates synapse maintenance by acting within the RPM-1 signaling network, but independent of the DLK-1 MAP3K.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani et al.
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    Sensorimotor pathway controlling stopping behavior during chemotaxis in the Drosophila melanogaster larva

    Ibrahim Tastekin et al.
    The reconstruction of a sensorimotor pathway from the olfactory-sensory neurons down to the pre-motor system reveals a descending neuron that plays a critical role in the organization of larval chemotaxis.

    Comparative genetic screens in human cells reveal new regulatory mechanisms in WNT signaling

    Andres M Lebensohn et al.
    A systematic genetic analysis comprising seven genome-wide screens in haploid human cells uncovered new regulatory mechanisms at most levels in the WNT signaling pathway.

    NPTX2 and cognitive dysfunction in Alzheimer’s Disease

    Mei-Fang Xiao et al.
    Dysfunction of pyramidal neuron-PV interneuron circuits contributes to cognitive failure in Alzheimer's disease.
