    Synteny-based analyses indicate that sequence divergence is not the main source of orphan genes

    Nikolaos Vakirlis et al.
    Homology information implicit in regions of conserved synteny allows quantification of gene origination by complete sequence divergence, revealing a larger-than-expected role for other mechanisms of origin, including de novo origination.

    Genetic Novelty: How new genes are born

    Urminder Singh, Eve Syrkin Wurtele
    Analysis of yeast, fly and human genomes suggests that sequence divergence is not the main source of orphan genes.

    The life cycle of Drosophila orphan genes

    Nicola Palmieri et al.
    The short lifetime of orphan genes is a major factor explaining the stability of gene number in Drosophila.

    Changes to social feeding behaviors are not sufficient for fitness gains of the Caenorhabditis elegans N2 reference strain

    Yuehui Zhao et al.
    Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

    Cis-regulatory evolution integrated the Bric-à-brac transcription factors into a novel fruit fly gene regulatory network

    Maxwell J Roeske et al.
    The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.

    Revised roles of ISL1 in a hES cell-based model of human heart chamber specification

    Roberto Quaranta et al.
    Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.

    Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies

    Silvia Urbansky et al.
    Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.

    Microglia contribute to circuit defects in Mecp2 null mice independent of microglia-specific loss of Mecp2 expression

    Dorothy P Schafer et al.
    In mouse models of Rett Syndrome, global loss of the Mecp2 gene induces microglia to engulf excess synapses, while microglia-specific loss or gain of Mecp2 has little impact on disease.

    FAK activity sustains intrinsic and acquired ovarian cancer resistance to platinum chemotherapy

    Carlos J Diaz Osterman et al.
    Genomic gains in ovarian cancer can promote cisplatin resistance via a FAK, Wnt/beta-catenin and Myc signaling pathway supporting pluripotency genes and tumorspheres that can acquire FAK dependence for survival.
