    Transient nuclear Prospero induces neural progenitor quiescence

    Sen-Lin Lai, Chris Q Doe
    A low-level pulse of the nuclear Prospero protein is necessary and sufficient to cause neural progenitor cells to enter a quiescent state.

    The Apelin receptor enhances Nodal/TGFβ signaling to ensure proper cardiac development

    Ashish R Deshwar et al.
    The Apelin receptor acts as a rheostat to ensure that the proper levels of Nodal signaling are achieved for proper cell fate specification at the onset of gastrulation, in particular for cardiac progenitor development.

    The C. elegans neural editome reveals an ADAR target mRNA required for proper chemotaxis

    Sarah N Deffit et al.
    Identification of tissue-specific RNA editing using a robust, publicly-available platform (SAILOR) reveals noncoding A-to-I editing events required for proper gene expression and neurological function, significantly advancing the understanding of how ADARs function in neural cells.

    The Drosophila Sp8 transcription factor Buttonhead prevents premature differentiation of intermediate neural progenitors

    Yonggang Xie et al.
    The Drosophila equivalent of the human transcription factor Sp8 acts to ensure that neural progenitor cells undergo an appropriate number of cell divisions, thereby helping to regulate brain development and guard against tumor formation.

    Kinetochores attached to microtubule-ends are stabilised by Astrin bound PP1 to ensure proper chromosome segregation

    Duccio Conti et al.
    Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.

    The Ormdl genes regulate the sphingolipid synthesis pathway to ensure proper myelination and neurologic function in mice

    Benjamin A Clarke et al.
    The ORMDL proteins function to restrain the de novo sphingolipid biosynthetic pathway during myelination, when there is a high demand for sphingolipids to prevent excessive accumulation of metabolic intermediates.

    Condensin I subunit Cap-G is essential for proper gene expression during the maturation of post-mitotic neurons

    Amira Hassan et al.
    The condensin I subunit Cap-G is expressed in post-mitotic neurons and its removal, especially from less mature neurons, results in gene expression changes, reduced survival and behavioural defects in Drosophila.

    LRP1 regulates peroxisome biogenesis and cholesterol homeostasis in oligodendrocytes and is required for proper CNS myelin development and repair

    Jing-Ping Lin et al.
    In oligodendrocyte progenitor cells, lipid metabolism and peroxisome biogenesis are regulated by the low-density lipoprotein related-receptor-1, and if disrupted, impair proper white matter development and adult repair.

    Transient inflammatory response mediated by interleukin-1β is required for proper regeneration in zebrafish fin fold

    Tomoya Hasegawa et al.
    The Interleukin 1 beta signaling and tissue inflammation act as a double-edged sword: they are required for regeneration, but when in excess, they impair tissue regeneration and induce apoptosis.

    Positive and negative incentive contrasts lead to relative value perception in ants

    Stephanie Wendt et al.
    Relative value perception, a basic tenant of Behavioural Economics, is demonstrated in an insect, and further shown to be driven by cognitive processes and induced by private and social information.
