    Wnt/β-catenin regulates an ancient signaling network during zebrafish scale development

    Andrew J Aman et al.
    Zebrafish scales depend on interactions among Wnt, Ectodysplasin and Hedgehog signaling pathways similar to those underlying feathers, teeth and hair follicles, suggesting a deep homology of ectodermal appendages in vertebrates.

    Cryo-EM structure of the polycystin 2-l1 ion channel

    Raymond E Hulse et al.
    The selectivity characteristics of PC-2L1, which make it a principal source of calcium in primary cilia function, is presented and advances understanding of the similarity and differences of TRPP ion channels.

    Introgression of regulatory alleles and a missense coding mutation drive plumage pattern diversity in the rock pigeon

    Anna I Vickrey et al.
    Different kinds of molecular changes at one genetic locus control different feather pigmentation patterns, and the darkest patterns resulted from hybridization with another species.

    Diversification of heart progenitor cells by EGF signaling and differential modulation of ETS protein activity

    Benjamin Schwarz et al.
    A novel regulatory model for the diversification of cardiac cell subpopulations in Drosophila is established by linking epidermal growth factor signaling with differential activities of key transcription factors.

    Gene family innovation, conservation and loss on the animal stem lineage

    Daniel J Richter et al.
    The genomes of animal progenitors evolved as mosaics of old, new, rearranged, and repurposed protein domains, genes and pathways and paved the way for the origin and evolution of animals.

    Signals from the brain and olfactory epithelium control shaping of the mammalian nasal capsule cartilage

    Marketa Kaucka et al.
    The brain and olfactory epithelium play a key role in pattering chondrogenic areas in the developing face, which is partly based on the release of SHH from neurosensory structures into the facial mesenchyme.

    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.

    A novel Cep120-dependent mechanism inhibits centriole maturation in quiescent cells

    Ewelina Betleja et al.
    Cells have evolved a mechanism that actively regulates centriole maturation during quiescence.

    Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria

    FoSheng Hsu et al.
    Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.
