    MS-275, a class 1 histone deacetylase inhibitor augments glucagon-like peptide-1 receptor agonism to improve glycemic control and reduce obesity in diet-induced obese mice

    Shilpak Bele et al.
    Class 1 histone deacetylase (HDAC) inhibitor MS-275 enhances the efficacy of glucagon-like peptide 1 receptor (GLP-1R) therapy for glycemic control and reduction of obesity.

    AMPK signaling to acetyl-CoA carboxylase is required for fasting- and cold-induced appetite but not thermogenesis

    Sandra Galic et al.
    A single mutation in acetyl-CoA carboxylase blocking AMPK regulation inhibits food intake in mice in response to cold exposure or fasting causing them to lose weight.

    Long-term consequences of the absence of leptin signaling in early life

    Angela M Ramos-Lobo et al.
    A mouse model that grew without functional leptin receptors until adulthood reveals that early defects in leptin signaling lead to permanent metabolic and developmental problems.

    The Rho-guanine nucleotide exchange factor PDZ-RhoGEF governs susceptibility to diet-induced obesity and type 2 diabetes

    Ying-Ju Chang et al.
    PDZ-RhoGEF controls adipose tissue abundance and whole body metabolism.

    Cold-induced hyperphagia requires AgRP neuron activation in mice

    Jennifer D Deem et al.
    A combination of neuroscience approaches and indirect calorimetry demonstrate a physiological role for AgRP neurons in cold-induced hyperphagia and strongly suggest temperature is an important regulator of AgRP neuron activity.

    An alternative splicing program promotes adipose tissue thermogenesis

    Santiago Vernia et al.
    NOVA pre-mRNA spacing factors suppress adipose tissue energy expenditure.

    Drp1 is required for AgRP neuronal activity and feeding

    Sungho Jin et al.
    Mitochondrial fission, associated with fatty acids oxidation, is fundamental for AgRP neuronal activity during negative energy balance and in regulating fasting- and/or ghrelin-induced feeding.

    Impaired skeletal muscle mitochondrial pyruvate uptake rewires glucose metabolism to drive whole-body leanness

    Arpit Sharma et al.
    Skeletal muscle mitochondrial pyruvate carrier disruption increases muscle fatty acid oxidation and systemic glucose turnover that drive whole-body leanness.

    Growth hormone-releasing hormone disruption extends lifespan and regulates response to caloric restriction in mice

    Liou Y Sun et al.
    Mice with a mutation that disrupts the release of growth hormone show greatly increased lifespan, which can be further increased by caloric restriction.

    Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

    Yuling Li et al.
    Animal RanBP1 nuclear export and cargo dissociation mechanisms are surprisingly different from yeast, due to mutations of critical residues, leading to greater nuclear transport efficiency and higher energy cost.
