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

    Zhipeng Zhou et al.
    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.

    Efficient termination of nuclear lncRNA transcription promotes mitochondrial genome maintenance

    Dorine Jeanne Mariëtte du Mee et al.
    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.

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

    Françoise S Howe et al.
    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.

    Bridged filaments of histone-like nucleoid structuring protein pause RNA polymerase and aid termination in bacteria

    Matthew V Kotlajich et al.
    Bridged H-NS filaments inhibit transcript elongation by bacterial RNA polymerase by enhancing backtracking and increasing Rho-dependent termination at a subset of pause sites that are normally poor Rho substrates.

    Active RNAP pre-initiation sites are highly mutated by cytidine deaminases in yeast, with AID targeting small RNA genes

    Benjamin JM Taylor et al.
    Transcribed promoters are highly susceptible to mutation by cytidine deaminases, implicating stable exposure of single stranded DNA structures, rather than cofactors, in localising mutation during tumourigenesis and antibody maturation.

    Pausing guides RNA folding to populate transiently stable RNA structures for riboswitch-based transcription regulation

    Hannah Steinert et al.
    The discontinuous speed of transcription enables riboswitch molecules to adopt meta-stable structures in response to the presence of their cognate ligand, thereby gene-regulation by means of structure induced transcription termination can occur.

    Regulation of alternative polyadenylation by Nkx2-5 and Xrn2 during mouse heart development

    Keisuke Nimura et al.
    A tissue-specific transcription factor is involved in the regulation of alternative polyadenylation in conjunction with a transcription termination factor.

    Science Forum: The Human Cell Atlas

    Aviv Regev et al.
    Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.

    Addressing the ethical issues raised by synthetic human entities with embryo-like features

    John Aach et al.
    Guidelines governing research into embryos need to be updated in a way that reflects the moral status of synthetic human entities generated using the methods of synthetic biology.
