    Fatty acid analogue N-arachidonoyl taurine restores function of IKs channels with diverse long QT mutations

    Sara I Liin et al.
    Fatty acid analogues are interesting prototype compounds that may inspire the development of future IKs channel activators to treat patients with long QT syndrome caused by diverse arrhythmia-causing mutations in the IKs channel.

    CNS myelination and remyelination depend on fatty acid synthesis by oligodendrocytes

    Penelope Dimas et al.
    Endogenous synthesis of fatty acids by oligodendrocytes is essential for development and repair in the central nervous system.

    Rv3723/LucA coordinates fatty acid and cholesterol uptake in Mycobacterium tuberculosis

    Evgeniya V Nazarova et al.
    The integral membrane protein LucA facilitates fatty acid and cholesterol uptake into Mycobacterium tuberculosis by stabilizing the Mce1 and Mce4 transporters, respectively, and Mce1 functions as a fatty acid transporter in Mycobacterium tuberculosis.

    The genetic requirements of fatty acid import by Mycobacterium tuberculosis within macrophages

    Evgeniya V Nazarova et al.
    An unbiased forward genetic screen identified genes in Mycobacterium tuberculosis that are required for fatty acid import when the bacterium is residing within macrophages.

    Molecular basis of fatty acid taste in Drosophila

    Ji-Eun Ahn et al.
    Molecular-genetic, neural imaging and behavioral analyses reveal how Drosophila melanogaster sense fatty acids, important nutrient compounds, through multimeric Ionoptropic Receptors complexes.

    The mitochondrial acyl carrier protein (ACP) coordinates mitochondrial fatty acid synthesis with iron sulfur cluster biogenesis

    Jonathan G Van Vranken et al.
    The essential function of ACP is not related to mitochondrial fatty acid and lipoic acid synthesis, but rather an evolutionarily-conserved role in iron sulfur cluster biogenesis.

    Resilience of small intestinal beneficial bacteria to the toxicity of soybean oil fatty acids

    Sara C Di Rienzi et al.
    Comparisons between lactobacilli bacteria in the small intestine and those evolved in the lab reveal several modes of resistance to toxic fatty acids.

    Expression of SREBP-1c Requires SREBP-2-mediated Generation of a Sterol Ligand for LXR in Livers of Mice

    Shunxing Rong et al.
    SREBP-2 directly regulates genes involved in cholesterol homeostasis and indirectly regulates fatty acid synthesis through the production of a ligand responsible for the activation of LXR and SREBP-1c.

    Accelerated phosphatidylcholine turnover in macrophages promotes adipose tissue inflammation in obesity

    Kasparas Petkevicius et al.
    Obesity leads to increased phosphatidylcholine turnover in adipose tissue macrophages that makes them susceptible to saturated fatty acid-induced inflammation.

    Dynamic repression by BCL6 controls the genome-wide liver response to fasting and steatosis

    Meredith A Sommars et al.
    B cell lymphoma 6 (BCL6) represses fasting gene expression by opposing peroxisome proliferator-activated receptor alpha (PPARa) activity at enhancers, and its ablation protects against steatosis by enhancing fatty acid catabolism.
