    Channel nuclear pore complex subunits are required for transposon silencing in Drosophila

    Marzia Munafò et al.
    By linking export and licensing of a piRNA precursor transcript, channel nuclear pore complex subunits Nup54 and Nup58 are specifically required to silence transposons in the Drosophila ovary.

    C9orf72 arginine-rich dipeptide repeat proteins disrupt karyopherin-mediated nuclear import

    Lindsey R Hayes et al.
    Poly-PR and poly-GR interact with importin β, disrupt importin-cargo loading, and inhibit nuclear import in permeabilized cells in a manner that can be rescued by RNA.

    Telomerase biogenesis requires a novel Mex67 function and a cytoplasmic association with the Sm7 complex

    Yulia Vasianovich et al.
    A new tool that allows specific subpopulations of telomerase RNAs in vivo forces a thorough revision of the telomerase maturation pathway and suggests a new function for Mex67.

    C. elegans orthologs MUT-7/CeWRN-1 of Werner syndrome protein regulate neuronal plasticity

    Tsung-Yuan Hsu et al.
    The olfactory learning of Caenorhabditis elegans shows that the exonuclease and helicase domains of human Werner syndrome protein (WRN) coordinately regulate the biogenesis of small interfering RNAs to promote neuronal plasticity.

    MicroRNA-122 supports robust innate immunity in hepatocytes by targeting the RTKs/STAT3 signaling pathway

    Hui Xu et al.
    The liver-specific miRNA microRNA-122 plays a previously unknown role in hepatocyte intrinsic innate immunity by targeting the RTKs/STAT3 signaling pathway.

    SRSF3 promotes pluripotency through Nanog mRNA export and coordination of the pluripotency gene expression program

    Madara Ratnadiwakara et al.
    RNA-binding protein SRSF3 mediates critical changes in RNA processing of pluripotency genes, which reveals functional consequences of regulated RNA processing during stem cell self-renewal and early development.

    Poly(A) tail length regulates PABPC1 expression to tune translation in the heart

    Sandip Chorghade et al.
    A poly(A) tail-based regulatory mechanism dynamically controls PABPC1 protein synthesis in cardiomyocytes and thereby titrates cellular translation in response to developmental and hypertrophic cues.

    Cross-talk between PRMT1-mediated methylation and ubiquitylation on RBM15 controls RNA splicing

    Li Zhang et al.
    Inhibiting PRMT1 enzymatic activity promotes megakaryocyte terminal differentiation via RBM15-mediated RNA metabolism, which is dysregulated in hematological malignancies.

    Cytoplasmic mRNA decay represses RNA polymerase II transcription during early apoptosis

    Christopher Duncan-Lewis et al.
    Human cells respond to cytoplasmic mRNA depletion during early apoptosis by inhibiting RNA polymerase II transcription, thereby magnifying the gene expression shutdown during stress.

    Molecular determinants of large cargo transport into the nucleus

    Giulia Paci et al.
    Efficient nuclear transport of very large biomolecules, relevant for viral transport, scales non-linearly with size and its kinetics can be explained by a simple two-parameter energetic model.
