    Alpha-satellite RNA transcripts are repressed by centromere–nucleolus associations

    Leah Bury et al.
    Single molecule FISH analysis defines the behavior of centromere-derived alpha-satellite transcripts in intact human cells and reveals a critical role for centromere-nucleolar contacts in repressing alpha-satellite transcription.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Programmed genome editing of the omega-1 ribonuclease of the blood fluke, Schistosoma mansoni

    Wannaporn Ittiprasert et al.
    Gene knock-out of the omega-1 ribonuclease of Schistosoma mansoni eggs resulted in immunologically impaired phenotype, showcasing the novel application of CRISPR/Cas9 genome editing and utility for functional genomics in schistosomes.

    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.

    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani et al.
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    Cell size sensing in animal cells coordinates anabolic growth rates and cell cycle progression to maintain cell size uniformity

    Miriam Bracha Ginzberg et al.
    Cells employ two strategies, adjusting both their cell cycle lengths and their growth rates in a size-dependent manner, to correct aberrations in cell size.

    Tenectin recruits integrin to stabilize bouton architecture and regulate vesicle release at the Drosophila neuromuscular junction

    Qi Wang et al.
    Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.

    Upregulation of neurovascular communication through filamin abrogation promotes ectopic periventricular neurogenesis

    Shauna L Houlihan et al.
    Analyses based on the mouse model of a human genetic disease reveal that the neuron production of cerebral tissue can be boosted by escalated signaling between neural progenitors and the vasculature.

    Calcium specificity signaling mechanisms in abscisic acid signal transduction in Arabidopsis guard cells

    Benjamin Brandt et al.
    The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.
