    Macrophage inflammation resolution requires CPEB4-directed offsetting of mRNA degradation

    Clara Suñer, Annarita Sibilio ... Raúl Méndez
    Decay rate of mRNAs encoding inflammatory regulators is controlled by the balance between AU-rich element-mediated deadenylation and cytoplasmic polyadenylation element-mediated polyadenylation.

    METTL3 promotes homologous recombination repair and modulates chemotherapeutic response in breast cancer by regulating the EGF/RAD51 axis

    Enjie Li, Mingyue Xia ... Zhigang Guo
    Biochemical approaches and cellular experiments show a novel effect of METTL3 on homologous recombination repair and chemotherapeutic response via the m6A-YTHDC1-dependent regulation of the EGF/RAD51 axis.

    A mechano-osmotic feedback couples cell volume to the rate of cell deformation

    Larisa Venkova, Amit Singh Vishen ... Matthieu Piel
    Whether deforming cells behave as elastic balls (deforming at constant volume) or as sponges (loosing volume as they deform) depends on how fast they change their shape, because the cell volume depends on the tension of the plasma membrane.

    Single-cell monitoring of dry mass and dry mass density reveals exocytosis of cellular dry contents in mitosis

    Teemu P Miettinen, Kevin S Ly ... Scott R Manalis
    A high-resolution approach for monitoring dry mass and the density of that dry mass on a single-cell level is developed and used to reveal that mammalian cells can lose components in mitosis due to lysosomal exocytosis.

    A bidirectional switch in the Shank3 phosphorylation state biases synapses toward up- or downscaling

    Chi-Hong Wu, Vedakumar Tatavarty ... Gina G Turrigiano
    Activity-dependent bidirectional changes in phosphorylation of the autism-associated scaffold protein Shank3 are essential for the expression of homeostatic synaptic plasticity.

    MDGAs are fast-diffusing molecules that delay excitatory synapse development by altering neuroligin behavior

    Andrea Toledo, Mathieu Letellier ... Olivier Thoumine
    MDGAs are highly diffusive molecules that alter both neuroligin-1 and AMPA receptor dynamics and function, thereby significantly delaying the differentiation of excitatory post-synapses.

    Microtubule assembly by tau impairs endocytosis and neurotransmission via dynamin sequestration in Alzheimer’s disease synapse model

    Tetsuya Hori, Kohgaku Eguchi ... Tomoyuki Takahashi
    Wild-type human recombinant tau protein infused in presynaptic terminals newly assembled microtubules, which sequestered cytosolic dynamins, thereby blocking synaptic vesicle endocytosis and causing activity-dependent rundown of excitatory synaptic transmission in a slice model of mouse brainstem.

    Oligogenic heterozygous inheritance of sperm abnormalities in mouse

    Guillaume Martinez, Charles Coutton ... Christophe Arnoult
    This first evidence of oligogenic inheritance in failed spermatogenesis strongly suggests that oligogenic heterozygosity could explain a significant proportion of asthenoteratozoospermia cases.

    Enhanced C/EBPβ function promotes hyperplastic versus hypertrophic fat tissue growth and prevents steatosis in response to high-fat diet feeding

    Christine Müller, Laura M Zidek ... Cornelis F Calkhoven
    Gene regulation by C/EBPβ determines how surplus of dietary fat is stored, which has consequences for metabolic health.

    Crotamiton derivative JM03 extends lifespan and improves oxidative and hypertonic stress resistance in Caenorhabditis elegans via inhibiting OSM-9

    Keting Bao, Wenwen Liu ... Jian Li
    In a chemical genetics study, JM03 derived from crotamiton, an inhibitor of trainsient receptor potential vanilloid-4 channels, was identified to extend lifespan and improve oxidative and hypertonic stress resistance in Caenorhabditis elegans via inhibiting OSM-9.
