    Structural basis of transcription arrest by coliphage HK022 Nun in an Escherichia coli RNA polymerase elongation complex

    Jin Young Kang, Paul Dominic B Olinares ... Seth A Darst
    Cryo-electron microscopy structures show how coliphage HK022 Nun blocks Escherichia coli RNA polymerase translocation by mediating multiple interactions between the RNA polymerase and nucleic acids.

    Translatome analysis reveals cellular network in DLK-dependent hippocampal glutamatergic neuron degeneration

    Erin M Ritchie, Dilan Acar ... Yishi Jin
    DLK signaling network reveals the conserved function in neuritogenesis and synapse formation, and highlights the regulation of c-Jun translation and microtubule homeostasis in hippocampal selective neuron vulnerability.

    Temperature stress induces mites to help their carrion beetle hosts by eliminating rival blowflies

    Syuan-Jyun Sun, Rebecca M Kilner
    Temperature, the presence of an enemy species and the density of the mutualistic partner species interact to determine the expression of a protective mutualism.

    Nuclear receptor Ftz-f1 promotes follicle maturation and ovulation partly via bHLH/PAS transcription factor Sim

    Elizabeth M Knapp, Wei Li ... Jianjun Sun
    Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.

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

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

    Endogenous itaconate is not required for particulate matter-induced NRF2 expression or inflammatory response

    Kaitlyn A Sun, Yan Li ... Gökhan M Mutlu
    Aconitate decarboxylase 1-derived itaconate reduces mitochondrial respiration via inhibition of succinate dehydrogenase but does not regulate inflammatory response or NRF2 expression in response to particulate matter.

    Distinct roles of striatal direct and indirect pathways in value-based decision making

    Shinae Kwak, Min Whan Jung
    The direct and indirect pathways of the dorsal striatum play indispensable roles in value-dependent action selection and value learning, respectively.
