    Synergistic assembly of human pre-spliceosomes across introns and exons

    Joerg E Braun, Larry J Friedman ... Melissa J Moore
    Viewing the dynamic interactions of individual spliceosomal subcomplexes with single pre-messenger RNA molecules reveals how nearby flanking splice sites accelerate pre-spliceosome assembly and the splicing of multi-intron pre-mRNAs.

    PHAROH lncRNA regulates Myc translation in hepatocellular carcinoma via sequestering TIAR

    Allen T Yu, Carmen Berasain ... David L Spector
    PHAROH lncRNA is upregulated in hepatocellular carcinoma and functions by sequestering the translational suppressor TIAR via a 71 nucleotide hairpin to regulate c-MYC translation.

    The nucleosome DNA entry-exit site is important for transcription termination and prevention of pervasive transcription

    A Elizabeth Hildreth, Mitchell A Ellison ... Karen M Arndt
    Disruption of the nucleosome DNA entry-exit site causes readthrough transcription of terminators, decreased nucleosome occupancy, and pervasive noncoding transcription, demonstrating this nucleosomal region protects the genome against inappropriate transcription.

    Codon usage biases co-evolve with transcription termination machinery to suppress premature cleavage and polyadenylation

    Zhipeng Zhou, Yunkun Dang ... Yi Liu
    Genetic and bioinformatic analyses uncover an unexpected role for codon usage biases in regulating gene expression at the transcriptional level by suppressing premature transcription termination.

    Prosurvival long noncoding RNA PINCR regulates a subset of p53 targets in human colorectal cancer cells by binding to Matrin 3

    Ritu Chaudhary, Berkley Gryder ... Ashish Lal
    Functional and mechanistic analysis of p53-regulated lncRNA PINCR and its interacting RNA-binding protein Matrin 3 uncovers context-dependent regulation of specific p53 target genes during DNA damage.

    Bidirectional promoter activity from expression cassettes can drive off-target repression of neighboring gene translation

    Emily Nicole Powers, Charlene Chan ... Gloria Ann Brar
    Bidirectional promoter activity, which is inherent to the promoters of selection cassettes used for genome editing, causes divergent transcription that can disrupt expression of genes neighboring cassette insertion sites, causing potent off-target effects.

    Small RNAs from mitochondrial genome recombination sites are incorporated into T. gondii mitoribosomes

    Sabrina Tetzlaff, Arne Hillebrand ... Christian Schmitz-Linneweber
    Sequences at mitochondrial genome recombination sites are dually used as mRNAs and as rRNAs in actively translating mitoribosomes of T. gondii.
