    Sulforaphane reduces obesity by reversing leptin resistance

    Işın Çakır, Pauline Lining Pan ... Masoud Ghamari-Langroudi
    Sulforaphane through NRF2-dependent and -independent cellular and molecular pathways alleviates leptin resistance to reverse the diet-induced obesity.

    Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes

    Emma C Walker, Kim Truong ... Natalie A Sims
    Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.

    The starvation hormone, fibroblast growth factor-21, extends lifespan in mice

    Yuan Zhang, Yang Xie ... David J Mangelsdorf
    Transgenic mice with high levels of FGF21 live for longer than wild-type mice and do so without reducing food intake.

    Leptin increases sympathetic nerve activity via induction of its own receptor in the paraventricular nucleus

    Zhigang Shi, Nicole E Pelletier ... Virginia L Brooks
    Leptin acts in the paraventricular nucleus to slowly increase sympathetic nerve activity to skeletal muscle and brown adipose tissue via induction of its own receptor in TRH glutamatergic neurons.

    Screening for insulin-independent pathways that modulate glucose homeostasis identifies androgen receptor antagonists

    Sri Teja Mullapudi, Christian SM Helker ... Didier YR Stainier
    Zebrafish insulin mutants serve as an innovative platform to identify novel mechanisms regulating glucose homeostasis.

    A genetic variant of fatty acid amide hydrolase (FAAH) exacerbates hormone-mediated orexigenic feeding in mice

    Georgia Balsevich, Gavin N Petrie ... Matthew N Hill
    A genetic knock-in mouse model reveals that the endocrine state governs the effect of the common fatty acid amide hydrolase C385A variant on body weight through a hypothalamic-mediated mechanism.
    1. Immunology and Inflammation

    Differences in the inflammatory proteome of East African and Western European adults and associations with environmental and dietary factors

    Godfrey S Temba, Nadira Vadaq ... Quirijn de Mast
    Comparing the inflammatory proteome of healthy Tanzanian and Dutch adults highlights a pro-inflammatory phenotype and metabolic differences in Tanzanians, with the potential role of food-derived metabolites in driving inflammation.

    Obesity causes selective and long-lasting desensitization of AgRP neurons to dietary fat

    Lisa R Beutler, Timothy V Corpuz ... Zachary A Knight
    Neurons that promote hunger become desensitized to dietary fat in obesity.

    LRG1 is an adipokine that promotes insulin sensitivity and suppresses inflammation

    Chan Hee J Choi, William Barr ... Paul Cohen
    Profiling the adipocyte secretome reveals LRG1 as a novel adipokine that promotes insulin sensitivity and modulates inflammation triggered by release of cytochrome c from dead/dying cells, describing a new pathway at the intersection of obesity and its systemic sequelae.

    Systematic functional analysis of rab GTPases reveals limits of neuronal robustness to environmental challenges in flies

    Friederike E Kohrs, Ilsa-Maria Daumann ... P Robin Hiesinger
    The first complete null mutant collection of all rab GTPase genes in a multicellular organism uncovers neuronal development and function sensitive to environmental challenges in Drosophila.
