    Senescent preosteoclast secretome promotes metabolic syndrome associated osteoarthritis through cyclooxygenase 2

    Weiping Su, Guanqiao Liu ... Mei Wan
    Under metabolic syndrome, joint subchondral preosteoclasts acquire a senescence-associated secretome, which causes a rapid structural alteration of subchondral bone and contributes to the development of osteoarthritis.

    Daple is a novel non-receptor GEF required for trimeric G protein activation in Wnt signaling

    Nicolas Aznar, Krishna K Midde ... Pradipta Ghosh
    Daple is a guanine nucleotide-exchange factor (GEF) for trimeric G proteins that enables Wnt/Frizzled receptors to transactivate G proteins during non-canonical Wnt signaling.

    The East Asian gut microbiome is distinct from colocalized White subjects and connected to metabolic health

    Qi Yan Ang, Diana L Alba ... Peter J Turnbaugh
    The gut microbiota of East Asians is distinct, dissociated from body mass, and self-sustains compared to White subjects from the same region, and therein may underpin a key health disparity.

    Single methyl groups can act as toggle switches to specify transmembrane Protein-protein interactions

    Li He, Helena Steinocher ... Daniel DiMaio
    The placement of single methyl groups at certain positions in the sequence of small model transmembrane proteins consisting solely of leucines and isoleucines can modulate highly specific, productive interactions with the transmembrane domain of the erythropoietin receptor.
