    Biosynthetic tailoring of existing ascaroside pheromones alters their biological function in C. elegans

    Yue Zhou, Yuting Wang ... Rebecca A Butcher
    In response to starvation, C. elegans converts a favorable pheromone that induces aggregation to an unfavorable one that induces a stress-resistant larval stage, thereby altering its chemical message without having to synthesize new pheromones de novo.

    Homeodomain-interacting protein kinase maintains neuronal homeostasis during normal Caenorhabditis elegans aging and systemically regulates longevity from serotonergic and GABAergic neurons

    Maria I Lazaro-Pena, Adam B Cornwell ... Andrew V Samuelson
    The transcriptional cofactor HPK-1 (homeodomain-interacting protein kinase) functions as a key regulator of multiple proteostatic stress responses, each originating from discrete neuronal subtypes within the Caenorhabditis elegans nervous system to preserve neuronal health and maintain organismal proteostasis during normal aging.
