    Bilateral regulation of EGFR activity and local PI(4,5)P2 dynamics in mammalian cells observed with superresolution microscopy

    Mitsuhiro Abe, Masataka Yanagawa ... Yasushi Sako
    The local PI(4,5)P2 nanodomain promotes the dimerization and activation of EGFR in the plasma membrane, whereas activated EGFR dissolves the nanodomain structure of PI(4,5)P2 through PLCγ.

    Heavy isotope labeling and mass spectrometry reveal unexpected remodeling of bacterial cell wall expansion in response to drugs

    Heiner Atze, Yucheng Liang ... Michel Arthur
    Labeling with 13C and 15N in the absence of metabolic engineering enabled the exploration of peptidoglycan metabolism at a very fine level of detail based on kinetic characterization of isotopologues predicted to occur according to known recycling and biosynthesis pathways.

    Circular RNA HMGCS1 sponges MIR4521 to aggravate type 2 diabetes-induced vascular endothelial dysfunction

    Ming Zhang, Guangyi Du ... Wei Chen
    Cardiovascular disease, the top cause of diabetic deaths, progresses via vascular endothelial dysfunction, with circHMGCS1 and miR4521 highlighted as potential markers for the development of this condition.

    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon, Sarah E Lower ... Jing-Ke Weng
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    SDR enzymes oxidize specific lipidic alkynylcarbinols into cytotoxic protein-reactive species

    Pascal Demange, Etienne Joly ... Sébastien Britton
    Deciphering the mechanism of action of a large family of natural and synthetic cytotoxic lipids bioactivated by enantiospecific oxidation into protein-reactive species inspires the development of enzyme-specific prodrugs.

    Canonical NF-κB signaling maintains corneal epithelial integrity and prevents corneal aging via retinoic acid

    Qian Yu, Soma Biswas ... Jing Li
    Corneal aging is regulated by the NF-κB-retinoic acid pathway and can be delayed by retinoic acid administration.

    Lytic transglycosylases mitigate periplasmic crowding by degrading soluble cell wall turnover products

    Anna Isabell Weaver, Laura Alvarez ... Tobias Dörr
    A critical role for bacterial lytic transglycosylases in the clearance of novel, toxic cell wall turnover products that accumulate during vegetative growth is identified through genetic approaches and compositional analysis of solubilized peptidoglycan released from the bacterial cell wall.
