    Establishment of developmental gene silencing by ordered polycomb complex recruitment in early zebrafish embryos

    Graham JM Hickey, Candice L Wike ... Bradley R Cairns
    Zebrafish early embryos initially package their developmental genes and enhancers in 'active' chromatin that subsequently receives polycomb repressive complex 1 (PRC1)-mediated histone H2A ubiquitylation, which confers silencing/poising – prior to Aebp2-PRC2-guided H3K27me3 addition.

    In vivo dynamics of skeletal muscle Dystrophin in zebrafish embryos revealed by improved FRAP analysis

    Fernanda Bajanca, Vinicio Gonzalez-Perez ... Simon M Hughes
    A multidisciplinary approach was used to translate the mathematical analysis of Dystrophin movements inside muscle cells into the biology of how Dystrophin interacts with the cell membrane.

    Competition between histone and transcription factor binding regulates the onset of transcription in zebrafish embryos

    Shai R Joseph, Máté Pálfy ... Nadine L Vastenhouw
    The relative levels of histones and transcription factors in the nucleus determine transcriptional output in zebrafish embryos.

    Noncaloric monosaccharides induce excessive sprouting angiogenesis in zebrafish via foxo1a-marcksl1a signal

    Xiaoning Wang, Jinxiang Zhao ... Dong Liu
    Live imaging and single-cell sequencing analyses on zebrafish models revealed that noncaloric monosaccharides and glucose similarly induce excessive blood vessel formation due to endothelial cells' increased formation of tip cells.

    A zebrafish embryo screen utilizing gastrulation identifies the HTR2C inhibitor pizotifen as a suppressor of EMT-mediated metastasis

    Joji Nakayama, Lora Tan ... Zhiyuan Gong
    Zebrafish embryo screen utilizing conserved mechanisms between cancer metastasis and zebrafish gastrulation identifies the HTR2C inhibitor pizotifen as anti-metastasis drugs.

    Systems biology derived source-sink mechanism of BMP gradient formation

    Joseph Zinski, Ye Bu ... Mary C Mullins
    Embryo-wide quantitative analysis of BMP signaling in zebrafish embryos, combined with a mathematical model-based computational screen, challenges the prevailing model of an antagonist counter-gradient shaping the gastrula BMP morphogen gradient and supports an antagonist sink with BMP diffusion mechanism.

    Dermomyotome-derived endothelial cells migrate to the dorsal aorta to support hematopoietic stem cell emergence

    Pankaj Sahai-Hernandez, Claire Pouget ... David Traver
    A rare population of endothelial cells emerges from a bipotent muscle progenitor population in the paraxial mesoderm and provides niche support to induce hematopoietic stem cells.

    TALE factors use two distinct functional modes to control an essential zebrafish gene expression program

    Franck Ladam, William Stanney ... Charles G Sagerström
    TALE transcription factors bind different genomic motifs and function together with different protein partners at different stages of zebrafish embryogenesis.

    TEADs, Yap, Taz, Vgll4s transcription factors control the establishment of Left-Right asymmetry in zebrafish

    Jonathan Fillatre, Jean-Daniel Fauny ... Bernard Thisse
    Transcription factors downstream of Hippo signaling control formation of the Left-Right Organizer by regulating major signaling pathways, expression of transcription factors and regulators of epigenetic programming involved in this process.

    DNA-damage induced cell death in yap1;wwtr1 mutant epidermal basal cells

    Jason KH Lai, Pearlyn JY Toh ... Timothy E Saunders
    Substrate rigidity modulates genomic stress in the epidermal basal cells of the developing zebrafish embryo and Yap1 and Wwtr1 are required for its survival.
