    The ER tether VAPA is required for proper cell motility and anchors ER-PM contact sites to focal adhesions

    Hugo Siegfried, Georges Farkouh ... Mélina L Heuzé
    Depletion of VAPA in cancer cells induces defects in actin organization, adhesion dynamics and cell migration, together with a perturbation of phosphoinositide levels at the plasma membrane and a lack of anchoring of ER-PM contact sites to focal adhesions.

    Rapid learning of predictive maps with STDP and theta phase precession

    Tom M George, William de Cothi ... Caswell Barry
    A close approximation to the successor representation is learnt by a simple spike-time-dependent learning rule between cells undergoing theta phase precession.

    Extensive cargo identification reveals distinct biological roles of the 12 importin pathways

    Makoto Kimura, Yuriko Morinaka ... Naoko Imamoto
    Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.

    Global morphogenetic flow is accurately predicted by the spatial distribution of myosin motors

    Sebastian J Streichan, Matthew F Lefebvre ... Boris I Shraiman
    Epithelial tissue remodeling during Drosophila embryonic development is quantitatively described by a simple law relating myosin activity and cell flow.

    Condensation tendency and planar isotropic actin gradient induce radial alignment in confined monolayers

    Tianfa Xie, Sarah R St Pierre ... Yubing Sun
    Radial alignment in confined cell monolayers with isotropic actin network is found to be mediated by the condensation tendency and tissue-scale actin gradient.

    Topological constraints in early multicellularity favor reproductive division of labor

    David Yanni, Shane Jacobeen ... Peter J Yunker
    Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.

    Mechanical basis and topological routes to cell elimination

    Siavash Monfared, Guruswami Ravichandran ... Amin Doostmohammadi
    Using self-organization, cells can collectively leverage defects in nematic and hexatic orders to localize mechanical stresses and remove an unwanted cell with their preferred path to achieve this explored here by independently tuning cell–cell and cell–substrate adhesion strengths.

    Nuclear receptor NR4A is required for patterning at the ends of the planarian anterior-posterior axis

    Dayan J Li, Conor L McMann, Peter W Reddien
    NR4A is a broadly conserved transcription factor that is required for concordance of patterning information and anatomy at both ends of the planarian anterior-posterior axis.

    Collateral deletion of the mitochondrial AAA+ ATPase ATAD1 sensitizes cancer cells to proteasome dysfunction

    Jacob M Winter, Heidi L Fresenius ... Jared Rutter
    A common genomic deletion in various human cancers disrupts mitochondrial protein homeostasis in a way that might be targeted by existing drugs.
