    MITF reprograms the extracellular matrix and focal adhesion in melanoma

    Ramile Dilshat, Valerie Fock ... Eirikur Steingrimsson
    Analysis of knockout and knockdown melanoma cells and TCGA melanoma data shows that the microphthalmia-associated transcription factor (MITF) is a major repressor of extracellular matrix (ECM) and focal adhesion genes.

    A Bayesian approach to dynamic homology of morphological characters and the ancestral phenotype of jawed vertebrates

    Benedict King, Martin Rücklin
    The ancestor of all known jawed vertebrates possessed a maxilla and premaxilla and was similar in morphology to the 'maxillate placoderms' from China.

    PI3K/Akt1 signalling specifies foregut precursors by generating regionalized extra-cellular matrix

    S Nahuel Villegas, Michaela Rothová ... Joshua M Brickman
    A signalling cascade involving PI3K/Akt1 remodels the extra-cellular matrix to achieve atypical cellular responses and control cell fate specification within the embryonic endoderm.

    Ebola and Marburg virus matrix layers are locally ordered assemblies of VP40 dimers

    William Wan, Mairi Clarke ... John AG Briggs
    Cryo-electron tomography reveals the structure and arrangement of the VP40 matrix protein lattice that mediates the formation of Ebola and Marburg virus particles.

    A novel Drosophila injury model reveals severed axons are cleared through a Draper/MMP-1 signaling cascade

    Maria D Purice, Arpita Ray ... Mary A Logan
    An unbiased transcriptional profiling screen reveals the secreted matrix metalloproteinase MMP-1 is a transcriptional target of the ensheathing glial receptor Draper following acute axon injury in adult Drosophila.

    Nr2f1a maintains atrial nkx2.5 expression to repress pacemaker identity within venous atrial cardiomyocytes of zebrafish

    Kendall E Martin, Padmapriyadarshini Ravisankar ... Joshua S Waxman
    The transcription factor Nr2f1a represses ventricular and pacemaker cardiomyocyte identities within distinct regions of the zebrafish atrium.

    Novelty and uncertainty differentially drive exploration across development

    Kate Nussenbaum, Rebecca E Martin ... Catherine A Hartley
    From middle childhood to early adulthood, the preference to engage with novel choice options remained consistent, but aversion to reward uncertainty increased.

    Flow environment and matrix structure interact to determine spatial competition in Pseudomonas aeruginosa biofilms

    Carey D Nadell, Deirdre Ricaurte ... Bonnie L Bassler
    The feedback between hydrodynamic flow conditions and biofilm spatial architecture drives competition in P. aeruginosa biofilms, and can explain variation in biofilm production observed among bacteria in natural environments.

    Dynamics of compartment-specific proteomic landscapes of hepatotoxic and cholestatic models of liver fibrosis

    Marketa Jirouskova, Karel Harant ... Martin Gregor
    A comprehensive proteomic map of liver fibrosis progression and healing in two mouse models identifies etiology-specific extracellular matrix components, laying the foundation for targeted antifibrotic therapies.

    A myristoyl switch at the plasma membrane triggers cleavage and oligomerization of Mason-Pfizer monkey virus matrix protein

    Markéta Častorálová, Jakub Sýs ... Tomas Ruml
    Biochemical and instrumental analysis showed that the membrane-induced exposure of myristoyl from the MA protein of Mason-Pfizer monkey virus triggers allosteric conformational changes resulting in MA oligomerization and unfolding of the cleavage site between MA and downstream domains of Gag.
