    Eukaryotic translation initiation factor 3 plays distinct roles at the mRNA entry and exit channels of the ribosomal preinitiation complex

    Colin Echeverría Aitken et al.
    Eukaryotic translation initiation factor 3 (eIF3) is required to stabilize the binding of mRNA at the exit channel of the small ribosomal subunit and acts at the entry channel to accelerate mRNA recruitment to the translation preinitiation complex.

    Loss of Frataxin induces iron toxicity, sphingolipid synthesis, and Pdk1/Mef2 activation, leading to neurodegeneration

    Kuchuan Chen et al.
    In Drosophila, the loss of Frataxin causes iron accumulation in the nervous system, which in turn enhances sphingolipid synthesis and activation of PDK1 and Mef2, which leads to neurodegeneration.

    The kinase DYRK1A reciprocally regulates the differentiation of Th17 and regulatory T cells

    Bernard Khor et al.
    A chemical biology approach has identified the kinase DYRK1A as a new regulator of the inflammatory response.

    Interplay of cell dynamics and epithelial tension during morphogenesis of the Drosophila pupal wing

    Raphaël Etournay et al.
    Autonomous patterns of cell contraction in the context of localized apical extracellular matrix constraints specify tissue stresses that reshape the wing epithelium.

    IK1 channels do not contribute to the slow afterhyperpolarization in pyramidal neurons

    Kang Wang et al.
    The slow afterhyperpolarization that follows a burst of action potentials is a powerful regulator of neuronal excitability and is not due to IK1 (KCNN4), a member of the SK channel family.

    NUDT21-spanning CNVs lead to neuropsychiatric disease and altered MeCP2 abundance via alternative polyadenylation

    Vincenzo A Gennarino et al.
    Individuals with deletions or duplications of the NUDT21 gene have altered levels of MeCP2 protein and intellectual disabilities.

    Mechanisms of ribosome stalling by SecM at multiple elongation steps

    Jun Zhang et al.
    Nascent regulatory peptides tune the translation rate through a continuous, dynamic reshaping of the functional center of the ribosome.

    Frequency-selective control of cortical and subcortical networks by central thalamus

    Jia Liu et al.
    Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.

    miR-34a is a microRNA safeguard for Citrobacter-induced inflammatory colon oncogenesis

    Lihua Wang et al.
    miR-34a prevents inflammation-induced colonic regeneration from oncogenesis by simultaneously targeting processes in both immune and epithelial cells, including T helper 17 cell differentiation, recruitment, and IL-17 induced epithelial proliferation.

    Atoh1-dependent rhombic lip neurons are required for temporal delay between independent respiratory oscillators in embryonic mice

    Srinivasan Tupal et al.
    The rhythmic patterns of activity that underlie breathing are generated and coordinated by distinct populations of neurons within the brainstem.
