    Cavin-3 dictates the balance between ERK and Akt signaling

    Victor J Hernandez, Jian Weng ... Peter Michaely
    Cavin-3 is a tumor suppressor protein that inhibits Akt signaling, suppresses Warburg metabolism, promotes apoptosis, and protects against cachexia.

    Inflammation produces catecholamine resistance in obesity via activation of PDE3B by the protein kinases IKKε and TBK1

    Jonathan Mowers, Maeran Uhm ... Alan R Saltiel
    Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.

    Nuclear receptor LRH-1/NR5A2 is required and targetable for liver endoplasmic reticulum stress resolution

    Jennifer L Mamrosh, Jae Man Lee ... David D Moore
    LRH-1/NR5A2 responds to ER stress by inducing a novel pathway that is required for stress resolution in mice and can be targeted by LRH-1 agonists.

    TAF4, a subunit of transcription factor II D, directs promoter occupancy of nuclear receptor HNF4A during post-natal hepatocyte differentiation

    Daniil Alpern, Diana Langer ... Irwin Davidson
    Physical and functional interactions between HNF4A and TAF4 coordinate HNF4A genomic occupancy with pre-initiation complex formation to activate post-natal hepatocyte gene expression.

    Lpcat3-dependent production of arachidonoyl phospholipids is a key determinant of triglyceride secretion

    Xin Rong, Bo Wang ... Peter Tontonoz
    The enzyme Lpcat3 plays a unique role in the incorporation of arachidonic acid into membranes, which is required for the production of lipoproteins.

    Recurrent gain of function mutation in calcium channel CACNA1H causes early-onset hypertension with primary aldosteronism

    Ute I Scholl, Gabriel Stölting ... Richard P Lifton
    A novel Mendelian disease featuring early-onset hypertension is caused by a recurrent gain of function mutation in CACNA1H, which encodes the voltage-gated calcium channel Cav3.2.

    The genetic architecture of NAFLD among inbred strains of mice

    Simon T Hui, Brian W Parks ... Aldons J Lusis
    A system genetics approach reveals a unique molecular signature of non-alcoholic fatty liver disease in mice and identifies novel genetic factors affecting hepatic steatosis.

    Precise let-7 expression levels balance organ regeneration against tumor suppression

    Linwei Wu, Liem H Nguyen ... Hao Zhu
    Mouse genetic studies reveal that let-7 performs potent tumor suppressive roles, but at the expense of regeneration and tissue homeostasis in the liver, findings with unanticipated therapeutic implications.

    The brown adipocyte protein CIDEA promotes lipid droplet fusion via a phosphatidic acid-binding amphipathic helix

    David Barneda, Joan Planas-Iglesias ... Mark Christian
    An interaction between the brown fat protein CIDEA and the phospholipid phosphatidic acid is vital for the expansion of intracellular lipid droplets for energy storage.
