    Clp protease and antisense RNA jointly regulate the global regulator CarD to mediate mycobacterial starvation response

    Xinfeng Li, Fang Chen ... Jin He
    Under starvation conditions, anti-carD antisense RNA and Clp protease work together to decrease the CarD level to mediate the adaptation and survival of mycobacterial cells.

    Tyrosine phosphorylation of RNA polymerase II CTD is associated with antisense promoter transcription and active enhancers in mammalian cells

    Nicolas Descostes, Martin Heidemann ... Jean-Christophe Andrau
    Genome-wide analysis reveals novel functions for a post-translational modification to the carboxy-terminal domain (CTD) of RNA Polymerase II in mammals.

    Antisense, but not sense, repeat expanded RNAs activate PKR/eIF2α-dependent ISR in C9ORF72 FTD/ALS

    Janani Parameswaran, Nancy Zhang ... Jie Jiang
    C9ORF72 antisense repeat expanded RNAs activate PKR/eIF2α dependent integrated stress response and cause neuronal toxicity independent of DPR proteins.

    Gene age shapes the transcriptional landscape of sexual morphogenesis in mushroom-forming fungi (Agaricomycetes)

    Zsolt Merényi, Máté Virágh ... László G Nagy
    Allele-specific expression, natural antisense transcripts, and developmental gene expression, but not RNA editing or developmental hourglass, act in concert to shape the transcriptome during the fruiting body formation of complex multicellular fungi.

    RNAP II CTD tyrosine 1 performs diverse functions in vertebrate cells

    Jing-Ping Hsin, Wencheng Li ... James L Manley
    Phosphorylation of tyrosine 1 in the carboxy-terminal domain (CTD) of the largest subunit of RNA Polymerase (RNAP) II functions to stabilize this domain, and facilitates turnover of upstream antisense RNAs.

    RNase III-mediated processing of a trans-acting bacterial sRNA and its cis-encoded antagonist

    Sarah Lauren Svensson, Cynthia Mira Sharma
    Functional characterization of a pair of cis-encoded antisense RNAs reveals a role for RNase III and antisense regulation in the biogenesis and regulatory activity of a bacterial virulence factor-regulating small RNA.

    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.

    Identification of an LGP2-associated MDA5 agonist in picornavirus-infected cells

    Safia Deddouche, Delphine Goubau ... Caetano Reis e Sousa
    A viral RNA has been identified as a specific MDA5 agonist in cells infected with encephalomyocarditis virus.

    CRISPRi is not strand-specific at all loci and redefines the transcriptional landscape

    Françoise S Howe, Andrew Russell ... Jane Mellor
    CRISPR interference (CRISPRi), which uses small guide RNAs to target catalytically dead Cas9 protein to chromatin, disrupts existing transcription units and generates new sites for initiation and termination of transcription on both strands of DNA.

    Transcription elongation is finely tuned by dozens of regulatory factors

    Mary Couvillion, Kevin M Harlen ... L Stirling Churchman
    NET-seq analysis of 41 S. cerevisiae transcription regulatory factors uncovers their differential and opposing effects on Pol II transcription elongation and antisense transcription, revealing that wild-type transcription is balanced by the joint impact of many regulators.
