    Condensin controls recruitment of RNA polymerase II to achieve nematode X-chromosome dosage compensation

    William S Kruesi et al.
    C. elegans equalizes the expression of X-chromosome genes between the sexes by reducing the recruitment of RNA polymerase II to promoters of X-linked genes in hermaphrodites, using a chromosome-restructuring complex called condensin.

    Translation inhibitory elements from Hoxa3 and Hoxa11 mRNAs use uORFs for translation inhibition

    Fatima Alghoul et al.
    Hoxa3 and Hoxa11 translation inhibitory elements block cap-dependent translation by using upstream open reading frames with distinct modes of action.

    Folding behavior of a T-shaped, ribosome-binding translation enhancer implicated in a wide-spread conformational switch

    My-Tra Le et al.
    Folding and unfolding pathways are described for a ribosome-binding 3' cap-independent translation enhancer at the center of a conformational rearrangement that is implicated in the transition from translation to replication of an RNA virus.

    RNAP II CTD tyrosine 1 performs diverse functions in vertebrate cells

    Jing-Ping Hsin et al.
    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.

    RAL GTPases mediate EGFR-driven intestinal stem cell proliferation and tumourigenesis

    Máté Nászai et al.
    Combined genetic experiments and cellular trafficking assays in Drosophila and mammalian models uncover a new role of RAS-like GTPases in EGFR signalling activation during tissue regeneration and tumourigenesis through regulation of EGFR internalisation.

    Comprehensive annotations of human herpesvirus 6A and 6B genomes reveal novel and conserved genomic features

    Yaara Finkel et al.
    Unbiased mapping of viral open reading frames (ORFs) and transcripts in HHV-6 genomes uncovers novel ORFs and lncRNAs that are conserved across betaherpesviruses.

    Translational initiation in E. coli occurs at the correct sites genome-wide in the absence of mRNA-rRNA base-pairing

    Kazuki Saito et al.
    E. coli ribosomes incapable of base-pairing with the Shine-Dalgarno sequence are still selective for annotated start sites, indicating these sites are hard-wired for initiation by other mRNA features.

    Role of the pre-initiation complex in Mediator recruitment and dynamics

    Elisabeth R Knoll et al.
    Genome-wide recruitment of Mediator and Pol II is reduced in yeast lacking the Med2-Med3-Med15 tail module triad, and Mediator association with gene promoters depends on Pol II, Taf1, and TBP.

    PIP2 depletion promotes TRPV4 channel activity in mouse brain capillary endothelial cells

    Osama F Harraz et al.
    TRPV4 channels in brain capillaries are suppressed by the phosphoinositide PIP2 and activated by receptor agonists implicated in neurovascular coupling.

    A stochastic epigenetic switch controls the dynamics of T-cell lineage commitment

    Kenneth KH Ng et al.
    The timing and outcome of mammalian cell lineage decisions can be controlled by slow, stochastic events on individual regulatory gene loci.
