    Age-related changes in polycomb gene regulation disrupt lineage fidelity in intestinal stem cells

    Helen M Tauc, Imilce A Rodriguez-Fernandez ... Heinrich Jasper
    Global, multi-angled genetic analyses identified an age-associated loss of stem cell lineage fidelity that was linked to changes in polycomb regulation in the Drosophila intestinal epithelium.

    New hypotheses of cell type diversity and novelty from orthology-driven comparative single cell and nuclei transcriptomics in echinoderms

    Anne Meyer, Carolyn Ku ... Veronica Hinman
    Understanding novel cell types and their evolutionary history is re-evaluated using single nuclei transcriptomic approaches and their inferred underlying gene regulatory networks.

    Information content differentiates enhancers from silencers in mouse photoreceptors

    Ryan Z Friedman, David M Granas ... Michael A White
    Silencers and enhancers targeted by a common transcription factor in photoreceptors are distinguished by the number and diversity of binding transcription factor binding sites they contain.

    Maternally regulated gastrulation as a source of variation contributing to cavefish forebrain evolution

    Jorge Torres-Paz, Julien Leclercq, Sylvie Rétaux
    Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

    A library of MiMICs allows tagging of genes and reversible, spatial and temporal knockdown of proteins in Drosophila

    Sonal Nagarkar-Jaiswal, Pei-Tseng Lee ... Hugo J Bellen
    A large collection of functional EGFP tagged proteins derived from MiMIC insertions allows examination of protein expression in unfixed tissues and efficient tissue specific reversible knock down of proteins.

    An atlas of neural crest lineages along the posterior developing zebrafish at single-cell resolution

    Aubrey GA Howard IV, Phillip A Baker ... Rosa A Uribe
    Single-cell dissection of recent neural crest derivatives in the vertebrate zebrafish reveals diverse transcriptomic signatures among differentiating posterior cell types during the embryonic to larval stage transition.

    Estrogen receptor alpha in the brain mediates tamoxifen-induced changes in physiology in mice

    Zhi Zhang, Jae Whan Park ... Stephanie M Correa
    Estrogen receptor alpha in the hypothalamus is required for the effects of chronic tamoxifen treament on gene expression, thermoregulation, bone, and movement in mice.

    A feedback loop between nonsense-mediated decay and the retrogene DUX4 in facioscapulohumeral muscular dystrophy

    Qing Feng, Lauren Snider ... Robert K Bradley
    Expression of the disease gene DUX4 inhibits RNA quality control in skeletal muscle, thereby stabilizing thousands of aberrant RNAs, including its own transcript.

    BRAFV600E cooperates with CDX2 inactivation to promote serrated colorectal tumorigenesis

    Naoya Sakamoto, Ying Feng ... Eric R Fearon
    Genetic analyses reveal how CDX2 and BRAF defects seen in serrated colorectal cancer (CRCs), a poor prognosis CRC subset, cooperate in tumorigenesis in humans and in a mouse cancer model.

    Cas9+ conditionally-immortalized macrophages as a tool for bacterial pathogenesis and beyond

    Allison W Roberts, Lauren M Popov ... Jeffery S Cox
    Combination of stem cell engineering and CRISPR technologies created a facile method to genetically manipulate macrophages, a multifunctional cell type that plays critical roles in immunity, cancer, and tissue homeostasis.
