    SIRT1 regulates sphingolipid metabolism and neural differentiation of mouse embryonic stem cells through c-Myc-SMPDL3B

    Wei Fan, Shuang Tang ... Xiaoling Li
    SIRT1, a cellular metabolic sensor, transcriptionally promotes sphingomyelin degradation in embryonic stem cells, which in turn modulates their membrane fluidity and neural differentiation.

    Molecular basis of force-from-lipids gating in the mechanosensitive channel MscS

    Bharat Reddy, Navid Bavi ... Eduardo Perozo
    The structure of the mechanosensitive channel MscS embedded in a lipid bilayer redefines the nature, location and importance of lipid–protein interactions in the gating of mechanosensitive channels.

    Plasmon resonance and the imaging of metal-impregnated neurons with the laser scanning confocal microscope

    Karen J Thompson, Cynthia M Harley ... Karen A Mesce
    A new method allows silver- and gold-labeled tissues to be imaged with confocal microscopy, avoiding the problem of fluorescence photobleaching.

    A critical role for heme synthesis and succinate in the regulation of pluripotent states transitions

    Damien Detraux, Marino Caruso ... Patricia Renard
    Accumulation of succinate during the in vitro modeling of embryonic stem cell state transition critically regulate cell fate.

    Genome-wide mapping of native co-localized G4s and R-loops in living cells

    Ting Liu, Xing Shen ... Zhihong Xue
    The newly developed antibody-free techniques, HepG4-seq for G-quadruplexes and HBD-seq for R-loops, robustly reveal the comprehensive maps of native G-quadruplexes and R-loops, as well as their roles in transcriptional regulation.

    State-specific morphological deformations of the lipid bilayer explain mechanosensitive gating of MscS ion channels

    Yein Christina Park, Bharat Reddy ... José D Faraldo-Gómez
    A theory is presented that explains why some ion channels tend to open in response to membrane stretching, which posits that channel closing is disfavored by the morphological energetics of the lipid bilayer, and increasingly so under lateral tension.

    Discovery of novel determinants of endothelial lineage using chimeric heterokaryons

    Wing Tak Wong, Gianfranco Matrone ... John P Cooke
    Bioinformatic analysis of gene expression in chimeric heterokaryons can identify novel regulators of cell lineage.

    Metabolic memory of Δ9-tetrahydrocannabinol exposure in pluripotent stem cells and primordial germ cells-like cells

    Roxane Verdikt, Abigail A Armstrong ... Patrick Allard
    Exposure of embryonic stem cells to physiological concentrations of Δ9-THC remodels cellular metabolism across differentiation.

    MicroRNA-deficient mouse embryonic stem cells acquire a functional interferon response

    Jeroen Witteveldt, Lisanne I Knol, Sara Macias
    MiRNA-mediated suppression of MAVS expression in embryonic stem cells is necessary to inactivate the type I interferon response.

    Mouse SAS-6 is required for centriole formation in embryos and integrity in embryonic stem cells

    Marta Grzonka, Hisham Bazzi
    Unlike mouse embryos, mouse embryonic stem cells are able to use a SAS-6-independent pathway for imperfect centriole biogenesis that is associated with a rich centrosomal milieu and robust PLK4 activity.
