    The Mitotic Exit Network integrates temporal and spatial signals by distributing regulation across multiple components

    Ian Winsten Campbell et al.
    By distributing regulation to both the GTPase and downstream kinases, the Mitotic Exit Network creates a single signal from spatial and temporal inputs.

    Cross-compartment signal propagation in the mitotic exit network

    Xiaoxue Zhou et al.
    The mitotic exit network signals from spindle pole bodies to the nucleolus through the dynamic localization of its terminal kinase complex Dbf2-Mob1.

    Spatial signals link exit from mitosis to spindle position

    Jill Elaine Falk et al.
    In yeast, exit from mitosis is triggered by the movement of one spindle pole body out of the mother cell into the bud, the future daughter cell.

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

    Matthew Robert Hannaford et al.
    The actomyosin network and phospho-regulation combine to polarize fate determinants at the Drosophila neuroblast cell cortex.

    A FRET-based study reveals site-specific regulation of spindle position checkpoint proteins at yeast centrosomes

    Yuliya Gryaznova et al.
    Daughter-cell-associated factors and centrosome-based regulation is important in mitotic exit and spindle position checkpoint control.

    Polo-like kinase acts as a molecular timer that safeguards the asymmetric fate of spindle microtubule-organizing centers

    Laura Matellán et al.
    Molecular and cell biology analyses reveal novel roles of Polo-like kinases in establishing non-random segregation patterns of spindle-associated microtubule-organizing centers during mitosis, a phenomenon linked with replicative cell aging.

    Co-movement of astral microtubules, organelles and F-actin by dynein and actomyosin forces in frog egg cytoplasm

    James F Pelletier et al.
    Live imaging of multiple cytoplasmic networks in frog egg extracts calls for new models for how egg cytoplasm is physically organized during cleavage divisions.

    Chromatin accessibility dynamics and single cell RNA-Seq reveal new regulators of regeneration in neural progenitors

    Anneke Dixie Kakebeen et al.
    Regenerating neural progenitors of the Xenopus tropicalis tail prioritize differentiation to motor neuron types earlier than proliferation, a decision partly regulated by the transcription factors Pbx3 and Meis1.

    Orderly assembly underpinning built-in asymmetry in the yeast centrosome duplication cycle requires cyclin-dependent kinase

    Marco Geymonat et al.
    The polarized orientation of the mitotic spindle in budding yeast arises from spindle pole structural and functional asymmetry subject to cell cycle control.

    Sequential perturbations to mouse corticogenesis following in utero maternal immune activation

    Cesar P Canales et al.
    Mid-gestational exposure to maternal immune activation drives a sequence of transcriptional signatures and developmental pathology in embryonic mouse cortex, culminating in altered lamination and cellular lineage specification.
