    The cAMP effector PKA mediates Moody GPCR signaling in Drosophila blood–brain barrier formation and maturation

    Xiaoling Li et al.
    A polarized Moody/protein kinase A pathway plays an unrecognized central role in controlling the enormous cell growth and blood–brain barrier integrity in a highly coordinated spatiotemporal manner in brain homeostasis.

    Pak1 and PP2A antagonize aPKC function to support cortical tension induced by the Crumbs-Yurt complex

    Cornelia Biehler et al.
    Cell biology analyses in Drosophila epithelial tissues reveal novel mechanisms connecting epithelial polarity proteins with Myosin-dependent cell contractility.

    The transcription factor Rreb1 regulates epithelial architecture, invasiveness, and vasculogenesis in early mouse embryos

    Sophie M Morgani et al.
    Loss of the transcription factor Rreb1 results perturbs epithelial architecture during mouse development resulting in invasive cell behaviors, severe cardiovascular defects, and embryonic lethality.

    Co-regulation and function of FOXM1/RHNO1 bidirectional genes in cancer

    Carter J Barger et al.
    FOXM1 is co-expressed with its bidirectional gene partner RHNO1, and the two genes promote DNA repair, cell growth and survival, and chemotherapy resistance in ovarian cancer.

    Spatiotemporal recruitment of RhoGTPase protein GRAF inhibits actomyosin ring constriction in Drosophila cellularization

    Swati Sharma, Richa Rikhy
    The RhoGTPase domain containing protein GRAF recruits to the cleavage furrow during myosin II assembly to hydrolyze Rho-GTP and restrict actomyosin contractility for regulating the time of onset of constriction during Drosophila cellularization.

    Methionine restriction breaks obligatory coupling of cell proliferation and death by an oncogene Src in Drosophila

    Hiroshi Nishida et al.
    Src, an oncogene, promotes both cell proliferation and cell death simultaneously, which can be regulated by dietary methionine.

    Glial insulin regulates cooperative or antagonistic Golden goal/Flamingo interactions during photoreceptor axon guidance

    Hiroki Takechi et al.
    Timely regulation of growth cone dynamics, including filopodial and cytoskeletal rearrangements through phosphorylation signals from glial cells, shapes the photoreceptor axon targeting.

    Rho1 activation recapitulates early gastrulation events in the ventral, but not dorsal, epithelium of Drosophila embryos

    Ashley Rich et al.
    Spatially and temporally patterned activation of the small GTPase Rho1 indicates that ventral-specific factors contribute to cell- and tissue-level behaviors during ventral furrow formation, the first step in Drosophila gastrulation.

    A novel checkpoint pathway controls actomyosin ring constriction trigger in fission yeast

    Tomás Edreira et al.
    In fission yeast cell wall stress triggers a cytokinesis blockage specifically in the onset of actomyosin ring constriction.

    Topology-driven protein-protein interaction network analysis detects genetic sub-networks regulating reproductive capacity

    Tarun Kumar et al.
    Regulatory networks of genes controlling different aspects of insect reproduction have been identified by a systems-level analysis of quantitative phenotypic information obtained from the loss of individual cell signaling genes.
