    Tuning self-renewal in the Arabidopsis stomatal lineage by hormone and nutrient regulation of asymmetric cell division

    Yan Gong, Julien Alassimone ... Dominique C Bergmann
    Quantitative live-cell time-lapse imaging reveals that the spatial and temporal degree of cortical polarity domains reflects stem-cell division capacity in cells of the Arabidopsis plant leaf epidermis.

    Selenium supplementation inhibits IGF-1 signaling and confers methionine restriction-like healthspan benefits to mice

    Jason D Plummer, Spike DL Postnikoff ... Jay E Johnson
    Dietary selenium supplementation confers to mice all of the short-term healthspan benefits of the longevity-promoting intervention methionine restriction, and thus may represent a method to promote healthy aging in mammals.

    Dynamic Na+/H+ exchanger 1 (NHE1) – calmodulin complexes of varying stoichiometry and structure regulate Ca2+-dependent NHE1 activation

    Lise M Sjøgaard-Frich, Andreas Prestel ... Stine Falsig Pedersen
    NHE1-CaM complexes of multiple stoichiometries regulate cellular Ca2+-dependent NHE1 activity and can contribute to NHE1 dimerization, the latter shown by the NMR structure of CaM linking two NHE1 cytosolic tails.

    Promoter-specific changes in initiation, elongation, and homeostasis of histone H3 acetylation during CBP/p300 inhibition

    Emily Hsu, Nathan R Zemke, Arnold J Berk
    CBP/p300 acetylation of histone H3 at promoters and enhancers stimulates transcriptional elongation through recruitment of the super-elongation complex and BRD4.

    3DeeCellTracker, a deep learning-based pipeline for segmenting and tracking cells in 3D time lapse images

    Chentao Wen, Takuya Miura ... Koutarou D Kimura
    A deep learning-based pipeline was developed for extracting cellular signals flexibly from moving cells in 3D time lapse images, and it outperformed previous methods under different imaging conditions.

    Uncovering a novel function of the CCR4-NOT complex in phytochrome A-mediated light signalling in plants

    Philipp Schwenk, David J Sheerin ... Andreas Hiltbrunner
    The light-activated plant photoreceptor phytochrome A binds to NOT9B to displace it from the CCR4-NOT complex, thereby de-repressing light signalling.

    All-trans retinoic acid induces synaptic plasticity in human cortical neurons

    Maximilian Lenz, Pia Kruse ... Andreas Vlachos
    The vitamin A derivative, all-trans retinoic acid, induces protein-synthesis-dependent synaptic plasticity in the human brain.

    Pre-complexation of talin and vinculin without tension is required for efficient nascent adhesion maturation

    Sangyoon J Han, Evgenia V Azarova ... Gaudenz Danuser
    Pre-complexation of vinculin with talin’s R8 domain facilitates nascent adhesion maturation by unfolding talin, increasing vinculin binding, and thereby transmitting traction forces to the environment.

    A common 1.6 mb Y-chromosomal inversion predisposes to subsequent deletions and severe spermatogenic failure in humans

    Pille Hallast, Laura Kibena ... Maris Laan
    In addition to its academic merits, characterizing the genetic determinants of male (in)fertility and identifying clinically actionable genetic variants can lead to improved diagnosis or even treatment of such conditions.

    Anti-fibrotic activity of a rho-kinase inhibitor restores outflow function and intraocular pressure homeostasis

    Guorong Li, Chanyoung Lee ... W Daniel Stamer
    An FDA-approved, rho-associated kinase inhibitor reverses fibrosis in the conventional outflow pathway of a mouse model of glaucoma and reverses ocular hypertension in patients with steroid glaucoma.
