    Fat body-specific reduction of CTPS alleviates HFD-induced obesity

    Jingnan Liu, Yuanbing Zhang ... Ji-Long Liu
    Genetic interaction and biochemical analyses have unveiled the crucial involvement of CTPS in the regulation of adipocyte growth, lipid metabolism, and metabolic adaptation in Drosophila, achieved through activating the PI3K-Akt-SREBP pathway.

    Angiopoietin-2 in white adipose tissue improves metabolic homeostasis through enhanced angiogenesis

    Yu A An, Kai Sun ... Philipp E Scherer
    Gain- and loss-of-function studies highlight the important role for angiopoietin-2 to maintain adipose tissue health during metabolic challenges.

    Tetrahydroxanthohumol, a xanthohumol derivative, attenuates high-fat diet-induced hepatic steatosis by antagonizing PPARγ

    Yang Zhang, Gerd Bobe ... Adrian F Gombart
    Identifying xanthohumol and its derivatives as PPARγ anatagonists provides new insight into how natural compounds beneficially treat obesity and metabolic syndrome, and provide new compounds for therapeutic development.

    Obesogenic diet induces circuit-specific memory deficits in mice

    Ioannis Bakoyiannis, Eva Gunnel Ducourneau ... Guillaume Ferreira
    Obesogenic diet intake throughout adolescence impairs different types of memory through overactivation of specific hippocampal efferent pathways and targeting these overactive pathways has therapeutic potential.

    Diet-induced loss of adipose hexokinase 2 correlates with hyperglycemia

    Mitsugu Shimobayashi, Amandine Thomas ... Michael N Hall
    A proteomics screening in mouse adipose tissue shows that loss of adipose Hexokinase 2 is a mechanism of obesity-induced insulin insensitivity.

    Maternal obesity may disrupt offspring metabolism by inducing oocyte genome hyper-methylation via increased DNMTs

    Shuo Chao, Jun Lu ... Zhao-Jia Ge
    Maternal obesity mouse model reveal that melatonin deficiency causes the genomic hyper-methylation of oocytes via increasing the expression of DNA methyltransferases.

    Energy imbalance alters Ca2+ handling and excitability of POMC neurons

    Lars Paeger, Andreas Pippow ... Peter Kloppenburg
    The development of diet-dependent obesity results in the deterioration of calcium homeostasis in pro-opiomelanocortin-expressing neurons and impaired function of the same neurons.

    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.

    CXCR3-expressing myeloid cells recruited to the hypothalamus protect against diet-induced body mass gain and metabolic dysfunction

    Natalia Mendes, Ariane Zanesco ... Licio A Velloso
    A subset of myeloid cells expressing CXCR3 is recruited to the hypothalamus and protects against the metabolic abnormalities generated in diet-induced obesity.
