    Leading edge maintenance in migrating cells is an emergent property of branched actin network growth

    Rikki M Garner, Julie A Theriot
    Computational simulations of actin network growth at the cell leading edge, combined with careful high-speed video microscopy measurements of leading edge shape fluctuations, suggest that Arp2/3 branching of the actin network occurs at an optimal angle to minimize fluctuations.

    Role of YAP in early ectodermal specification and a Huntington's Disease model of human neurulation

    Francesco M Piccolo, Nathaniel R Kastan ... Ali H Brivanlou
    In a model of human neurulation (neuruloids), YAP is deferentially regulated across ecotodermal lineages, where it contributes to their differentiation and structural organization, and is hyper-active upon HD mutation, contributing to an HD-signature phenotype.

    DNA circles promote yeast ageing in part through stimulating the reorganization of nuclear pore complexes

    Anne C Meinema, Anna Marzelliusardottir ... Yves Barral
    Acetylation of nuclear basket components, following their interaction with accumulating extrachromosomal DNA circles, drives the reorganization of nuclear pore complexes and the loss of cellular viability associated with replicative ageing.

    Microtubule rescue at midzone edges promotes overlap stability and prevents spindle collapse during anaphase B

    Manuel Lera-Ramirez, François J Nédélec, Phong T Tran
    A simple mechanism relying on microtubule rescues occurring at midzone edges allows fission yeast spindles to elongate during anaphase B while maintaining microtubule overlaps, without the need to precisely regulate microtubule growth speed.

    MCMBP promotes the assembly of the MCM2–7 hetero-hexamer to ensure robust DNA replication in human cells

    Yuichiro Saito, Venny Santosa ... Masato T Kanemaki
    The MCM-binding protein (MCMBP) promotes the hexamer assembly of the replicative MCM2–7 helicase by interacting with the nascent MCM3 subunit, playing a key role in achieving high expression levels of the functional MCM2–7 helicase for maintaining genome integrity.

    High and stable ATP levels prevent aberrant intracellular protein aggregation in yeast

    Masak Takaine, Hiromi Imamura, Satoshi Yoshida
    The first demonstration that cellular ATP homeostasis suppresses high volatility of cellular ATP levels to ensure proteostasis that prevents accumulation of cytotoxic protein aggregation.

    Global analysis of cell behavior and protein dynamics reveals region-specific roles for Shroom3 and N-cadherin during neural tube closure

    Austin T Baldwin, Juliana H Kim ... John B Wallingford
    Tissue-level cell tracking and analysis of actomyosin and N-cadherin adhesion dynamics, coupled with disruption of the regulatory gene Shroom3, reveals region-specific cell behaviors along the anteroposterior axis during neural tube closure.

    SLC38A2 provides proline to fulfill unique synthetic demands arising during osteoblast differentiation and bone formation

    Leyao Shen, Yilin Yu ... Courtney M Karner
    Proline is essential for osteoblast differentiation and bone formation by facilitating the production of proline-enriched osteoblast proteins.

    Innervation modulates the functional connectivity between pancreatic endocrine cells

    Yu Hsuan Carol Yang, Linford JB Briant ... Didier YR Stainier
    Intercellular communication is critical for organ function, and the role of innervation in mediating this communication is of relevance to many fields, including developmental biology, neuroendocrinology, and disease pathophysiology.

    Lack of Tgfbr1 and Acvr1b synergistically stimulates myofibre hypertrophy and accelerates muscle regeneration

    Michèle MG Hillege, Andi Shi ... Richard T Jaspers
    Muscle hypertrophy and regeneration are critically regulated by combination of TGF-β type I receptors in myofibres.
