    AMPK acts as a molecular trigger to coordinate glutamatergic signals and adaptive behaviours during acute starvation

    Moloud Ahmadi, Richard Roy
    AMP-activated protein kinase directly coordinates glutamatergic signalling during starvation in C. elegans.

    Distributing tasks via multiple input pathways increases cellular survival in stress

    Alejandro A Granados et al.
    Single-cell experiments and mathematical modelling show that cellular signalling networks are vulnerable to trade-offs in speed versus accuracy, but that these vulnerabilities can be overcome by distributing the two tasks to different, although interacting, subnetworks.

    Limited inhibition of multiple nodes in a driver network blocks metastasis

    Ali Ekrem Yesilkanal et al.
    Low-dose treatment targeting multiple pathways of a pro-metastatic signaling network reduces the metastatic output of heterogeneous tumors while minimizing compensatory network activation.

    AMP-activated protein kinase fortifies epithelial tight junctions during energetic stress via its effector GIV/Girdin

    Nicolas Aznar et al.
    An effector of AMPK is essential for the kinase and its pharmacological activators, including Metformin, to strengthen cell-cell junctions and preserve epithelial cell polarity and barrier functions in the face of energetic stress, as well as to suppress oncogenesis.

    Preferential assembly of heteromeric kainate and AMPA receptor amino terminal domains

    Huaying Zhao et al.
    Members of kainate and AMPA families of glutamate receptors exhibit large differences in affinity for homo- and hetero-dimerziation of their amino terminal domains, which may control gating characteristics and ion selectivity of receptor subtypes with different subunit composition.

    Polo-like kinase 1 induces epithelial-to-mesenchymal transition and promotes epithelial cell motility by activating CRAF/ERK signaling

    Jianguo Wu et al.
    Overexpression of PLK1 triggers oncogenic transformation and transcriptional reprogramming of prostate epithelial cells, which stimulates cell migration and invasion.

    Disease-related mutations in PI3Kγ disrupt regulatory C-terminal dynamics and reveal a path to selective inhibitors

    Manoj K Rathinaswamy et al.
    The c-terminus of PI3K plays a key role in regulating kinase activity, with c-terminal disease-linked mutations leading to either activation or inhibition, which reveal a path to specific inhibitors.

    Transcriptome maps of general eukaryotic RNA degradation factors

    Salma Sohrabi-Jahromi et al.
    Mapping of 30 general RNA degradation factors onto the yeast transcriptome provides the global distribution of factors for RNA turnover and surveillance in a eukaryotic cell.

    The kinase DYRK1A reciprocally regulates the differentiation of Th17 and regulatory T cells

    Bernard Khor et al.
    A chemical biology approach has identified the kinase DYRK1A as a new regulator of the inflammatory response.

    High-resolution, genome-wide mapping of positive supercoiling in chromosomes

    Monica S Guo et al.
    GapR-seq enables the global mapping of positive supercoiling in bacteria and yeast, revealing positive supercoils downstream of highly expressed genes and, in yeast, associated with centromeres, pericentromeres, telomeres, replication origins, and R-loops.
