    HNRNPM controls circRNA biogenesis and splicing fidelity to sustain cancer cell fitness

    Jessica SY Ho, Federico Di Tullio ... Ernesto Guccione
    HNRNPM regulates exon inclusion and circularization events on transcripts of key homeostatic genes promoting cancer growth.

    RNA polymerase errors cause splicing defects and can be regulated by differential expression of RNA polymerase subunits

    Lucas B Carey
    A single human cell makes 10-100 transcriptional errors per second; these errors affect splicing and may influence the evolution of coding sequences.

    tRNA ligase structure reveals kinetic competition between non-conventional mRNA splicing and mRNA decay

    Jirka Peschek, Peter Walter
    Interconnected RNA processing mechanisms ensure the fidelity of non-conventional mRNA splicing during the unfolded protein response.

    In vitro proteasome processing of neo-splicetopes does not predict their presentation in vivo

    Gerald Willimsky, Christin Beier ... Peter M Kloetzel
    Analysis of neo-splicetope-specific T cell responses strongly questions the idea that in vitro proteasome-catalyzed peptide splicing reaction simulates the in vivo situation with the same high fidelity as the in vitro generation of non-spliced epitopes.

    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.

    Splicing repression allows the gradual emergence of new Alu-exons in primate evolution

    Jan Attig, Igor Ruiz de los Mozos ... Jernej Ule
    During evolutionary progression of Alu-exons, repressive U-tracts buffer sudden gains in 3' splice site strength and prevent inclusion of cryptic exons.

    m6A modification of U6 snRNA modulates usage of two major classes of pre-mRNA 5’ splice site

    Matthew T Parker, Beth K Soanes ... Gordon G Simpson
    High throughput sequencing of Arabidopsis mutants lacking the U6 snRNA methyltransferase FIONA1/METTL16 uncovers the role of U6 methylation in splicing signal preferences.

    Determining the genetic basis of anthracycline-cardiotoxicity by molecular response QTL mapping in induced cardiomyocytes

    David A Knowles, Courtney K Burrows ... Yoav Gilad
    Genetic variants that modulate transcriptomic response to doxorubicin in human iPSC-derived cardiomyocytes are predictive of cardiac damage and in vivo sensitivity to anthracycline cardiotoxicity.

    Engineering ER-stress dependent non-conventional mRNA splicing

    Weihan Li, Voytek Okreglak ... Peter Walter
    Ire1's RNase specificity and its cleavage sites coordination shape the evolutionary specialization of the unfolded protein response.

    miR-124 controls male reproductive success in Drosophila

    Ruifen Weng, Jacqueline SR Chin ... Stephen M Cohen
    A small RNA molecule called miR-124 controls pheromone production and sexual behaviour in Drosophila by regulating sex-specific gene expression in males.
