    Histone gene replacement reveals a post-transcriptional role for H3K36 in maintaining metazoan transcriptome fidelity

    Michael P Meers, Telmo Henriques ... A Gregory Matera
    Post-translational modification of histone H3K36 is not required to suppress cryptic transcription initiation or to include alternative exons in Drosophila; instead it promotes expression of active genes by stimulating polyadenylation.

    Gut microbiota induces high platelet response in patients with ST segment elevation myocardial infarction after ticagrelor treatment

    Xi Zhang, Xiaolin Zhang ... Yaling Han
    After myocardial infarction, gut microbiota affects platelet aggregation rate by regulating the absorption and metabolism of ticagrelor.

    Peroxisomal dysfunctions cause lysosomal storage and axonal Kv1 channel redistribution in peripheral neuropathy

    Sandra Kleinecke, Sarah Richert ... Celia Michèle Kassmann
    Dysfunctions of myelin peroxisomes cause a lysosomal storage-like disorder associated with alterations in glial and axonal membranes, which is the likely cause of nerve impairment in peroxisomal disorders.

    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies, Norbert Volkmar ... Paul J Lehner
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    Inhibition of post-termination ribosome recycling at premature termination codons in UPF1 ATPase mutants

    Lucas D Serdar, DaJuan L Whiteside ... Kristian E Baker
    Nucleotide resolution mapping of ribosome-bound RNA decay fragments in yeast cells expressing ATPase-deficient UPF1 reveals 3' UTR bound ribosomes and a role for UPF1 in post-termination ribosome recycling.

    Orai-mediated calcium entry determines activity of central dopaminergic neurons by regulation of gene expression

    Rishav Mitra, Shlesha Richhariya, Gaiti Hasan
    Expression of the appropriate repertoire of membrane channels, essential for activity of flight-promoting central dopaminergic neurons of Drosophila, requires store-operated Ca2+ entry during late pupal development and early adults.

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

    Shunxing Rong, Víctor A Cortés ... Jay D Horton
    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.

    Glutathione binding to the plant AtAtm3 transporter and implications for the conformational coupling of ABC transporters

    Chengcheng Fan, Douglas C Rees
    Multiple cryo-electron microscopy structures of a plant ABC transporter exporting glutathione derivatives captured a closed conformation proposed to enforce the export directionality, while a complex central to the coupling mechanism containing both glutathione and closed nucleotide binding domains remains elusive.

    Structures of translationally inactive mammalian ribosomes

    Alan Brown, Matthew R Baird ... Sichen Shao
    Mining electron cryomicroscopy data reveals new ribosomal interactions that preclude translation to potentially regulate gene expression.

    An essential cell-autonomous role for hepcidin in cardiac iron homeostasis

    Samira Lakhal-Littleton, Magda Wolna ... Peter A Robbins
    The novel role of hepcidin in cell-autonomous iron regulation changes our understanding of tissue-specific iron control, and of its interplay with systemic iron homeostasis.
