    Pervasive transcription fine-tunes replication origin activity

    Tito Candelli, Julien Gros, Domenico Libri
    The pervasive transcription environment alters the efficiency of firing of replication origins, which are 'protected' by roadblock termination due to origin recognition complex (ORC) and pre-RC complexes.

    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.

    Transcription leads to pervasive replisome instability in bacteria

    Sarah M Mangiameli, Christopher N Merrikh ... Houra Merrikh
    Replication-transcription conflicts cause pervasive replisome instability.

    Pervasive transcription read-through promotes aberrant expression of oncogenes and RNA chimeras in renal carcinoma

    Ana R Grosso, Ana P Leite ... Sérgio F de Almeida
    Transcription beyond annotated gene boundaries expands the diversity of the cancer transcriptome with overexpressed oncogenes and RNA chimeras.

    Quality control of transcription start site selection by nonsense-mediated-mRNA decay

    Christophe Malabat, Frank Feuerbach ... Alain Jacquier
    RNA polymerase II generates numerous transcript isoforms, including transcripts initiating downstream of the START codon, that are efficiently degraded by the nonsense-mediated mRNA decay pathway.

    Endogenous RNA interference is driven by copy number

    Cristina Cruz, Jonathan Houseley
    The ability to target transcripts from high-copy regions of the genome is an emergent property of a minimal RNA interference system.

    Evidence for a common evolutionary rate in metazoan transcriptional networks

    Anne-Ruxandra Carvunis, Tina Wang ... Trey Ideker
    Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.

    Single-nuclei characterization of pervasive transcriptional signatures across organs in response to COVID-19

    The COVID Tissue Atlas Consortium, Alejandro A Granados ... Bruce Wang
    A conserved transcriptional signature in macrophages and endothelial cells occurs in multiple organs in response to COVID-19 and suggests potential molecular interactions between the two cell types.

    Neuroblast-specific open chromatin allows the temporal transcription factor, Hunchback, to bind neuroblast-specific loci

    Sonia Q Sen, Sachin Chanchani ... Chris Q Doe
    Spatial factors generate neuroblast-specific open chromatin, thereby biasing the subsequent binding of transcription factors to produce neuroblast-specific neurons.

    Efficient termination of nuclear lncRNA transcription promotes mitochondrial genome maintenance

    Dorine Jeanne Mariëtte du Mee, Maxim Ivanov ... Sebastian Marquardt
    RNA Polymerase II transcriptional termination of a nuclear long non-coding RNA is required to maintain the mitochondrial genome and hence promotes budding yeast growth.
