    Multiple 9-1-1 complexes promote homolog synapsis, DSB repair, and ATR signaling during mammalian meiosis

    Catalina Pereira, Gerardo A Arroyo-Martinez ... Robert S Weiss
    Alternative 9-1-1 complexes have evolved to play essential roles in mammalian meiosis and function to activate the protein kinase ATR and promote key meiotic events necessary for fertility.

    Ngn1 inhibits astrogliogenesis through induction of miR-9 during neuronal fate specification

    Jing Zhao, Quan Lin ... Yi Sun
    During neurogenesis, Neurogenin 1 activates the microRNA miR-9, which directly targets the Jak-Stat pathway to inhibit astrogliogenesis.

    Developmental programming modulates olfactory behavior in C. elegans via endogenous RNAi pathways

    Jennie R Sims, Maria C Ow ... Sarah E Hall
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.

    Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint

    Nicolas Bigot, Matthew Day ... Laurence H Pearl
    Two phosphorylation sites on 53BP1 are found to mediate interaction with TOPBP1-RAD9 and shown to be essential for assembling the G1 DNA damage checkpoint response apparatus.

    Infection-exposure in infancy is associated with reduced allergy-related disease in later childhood in a Ugandan cohort

    Lawrence Lubyayi, Harriet Mpairwe ... Alison M Elliott
    In a Ugandan birth cohort, early childhood infection-exposure, notably to malaria, helminths, and diarrhoea, is associated with lower prevalence of atopy and allergy-related diseases in later childhood.

    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.

    Estimating the potential to prevent locally acquired HIV infections in a UNAIDS Fast-Track City, Amsterdam

    Alexandra Blenkinsop, Mélodie Monod ... Oliver Ratmann
    Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.

    Vicia faba SV channel VfTPC1 is a hyperexcitable variant of plant vacuole Two Pore Channels

    Jinping Lu, Ingo Dreyer ... Rainer Hedrich
    Polymorphic residues of a vacuolar Ca2+ sensor site in TPC1 channels differ between species of Brassicacea and Fabaceae and lead to distinct TPC1 gating behavior.

    Magnetic resonance measurements of cellular and sub-cellular membrane structures in live and fixed neural tissue

    Nathan H Williamson, Rea Ravin ... Peter J Basser
    Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.
