    Hidden long-range memories of growth and cycle speed correlate cell cycles in lineage trees

    Erika E Kuchen, Nils B Becker ... Thomas Höfer
    The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.

    Oversized cells activate global proteasome-mediated protein degradation to maintain cell size homeostasis

    Shixuan Liu, Ceryl Tan ... Ran Kafri
    Oversized mammalian cells reduce their growth efficiency by activating global protein degradation, which functions in parallel with the cell size checkpoints, to promote cell size homeostasis.

    Size uniformity of animal cells is actively maintained by a p38 MAPK-dependent regulation of G1-length

    Shixuan Liu, Miriam Bracha Ginzberg ... Ran Kafri
    The p38 MAPK pathway functions downstream of a cell-size-sensing process to coordinate cell size/growth with G1 progression in animal cells.

    Identification of abscission checkpoint bodies as structures that regulate ESCRT factors to control abscission timing

    Lauren K Strohacker, Douglas R Mackay ... Katharine S Ullman
    Cytoplasmic bodies sequester important abscission machinery to delay completion of cytokinesis in response to mitotic errors.

    Checkpoint inhibition of origin firing prevents inappropriate replication outside of S-phase

    Mark C Johnson, Geylani Can ... Philip Zegerman
    The S-phase checkpoint has roles in all phases of the cell cycle, which has implications for the majority of cancers that lack cell cycle controls.

    A pH-dependent cluster of charges in a conserved cryptic pocket on flaviviral envelopes

    Lorena Zuzic, Jan K Marzinek ... Peter J Bond
    Benzene mapping simulations of envelope protein rafts from six different flaviviruses reveal a conserved cryptic site whose cluster of ionisable residues is likely responsible for orchestrating pH-dependent conformational changes during fusion, thereby representing an attractive target for antiviral development.

    Negative regulation of G2-M by ATR (mei-41)/Chk1(Grapes) facilitates tracheoblast growth and tracheal hypertrophy in Drosophila

    Amrutha Kizhedathu, Archit V Bagul, Arjun Guha
    ATR/Chk1 contribute to G2 arrest in developing tracheoblasts, and arrest in G2 facilitates cellular and hypertrophic organ growth.

    Cell size sensing in animal cells coordinates anabolic growth rates and cell cycle progression to maintain cell size uniformity

    Miriam Bracha Ginzberg, Nancy Chang ... Marc W Kirschner
    Cells employ two strategies, adjusting both their cell cycle lengths and their growth rates in a size-dependent manner, to correct aberrations in cell size.

    Multiple inputs ensure yeast cell size homeostasis during cell cycle progression

    Cecilia Garmendia-Torres, Olivier Tassy ... Gilles Charvin
    Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.

    The equatorial position of the metaphase plate ensures symmetric cell divisions

    Chia Huei Tan, Ivana Gasic ... Patrick Meraldi
    Human cells center the position of the metaphase plate before anaphase onset to ensure the formation of equal-sized daughter cells.
