Hedgehog signaling is required at multiple stages of zebrafish tooth developmentWilliam R Jackman
Department of Biology, Bowdoin College, Brunswick, ME 04011, USA
BMC Dev Biol 10:119. 2010..In mammals, hedgehog signaling is known to be essential for multiple stages of odontogenesis; however, potential roles for the pathway during initiation of tooth development or in later morphogenesis are incompletely understood...- Zebrafish dentition in comparative contextDavid W Stock
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, Colorado 80309 0334, USA
J Exp Zool B Mol Dev Evol 308:523-49. 2007..Such studies may reveal the relative contribution to trends in dental evolution of biases in the generation of variation and sorting of this variation by selection or drift... - Developmental genetic mechanisms of evolutionary tooth loss in cypriniform fishesDavid W Stock
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO 80309 0334, USA
Development 133:3127-37. 2006..We hypothesize that a loss of Fgf signaling to oral epithelium was associated with cypriniform tooth loss... - The Dlx gene complement of the leopard shark, Triakis semifasciata, resembles that of mammals: implications for genomic and morphological evolution of jawed vertebratesDavid W Stock
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, Colorado 80309 0334, USA
Genetics 169:807-17. 2005..Dlx genes are known to be involved in jaw development, and changes in Dlx gene number are mapped to the same branch of the vertebrate tree as the origin of jaws... - The genetic basis of modularity in the development and evolution of the vertebrate dentitionD W Stock
Department of Environmental, Population, and Organismic Biology, University of Colorado, Boulder, CO 80309 0334, USA
Philos Trans R Soc Lond B Biol Sci 356:1633-53. 2001..Extension of research on the genetic control of tooth development to this and other vertebrate groups has great potential to further the understanding of modularity in the dentition... - Fgf signaling is required for zebrafish tooth developmentWilliam R Jackman
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO 80309 0334, USA
Dev Biol 274:139-57. 2004..Further work will be required to elucidate the nature of these signals, particularly with respect to their origins and whether they act through the mesenchyme... - Conservation and divergence of Bmp2a, Bmp2b, and Bmp4 expression patterns within and between dentitions of teleost fishesSarah B Wise
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO 80309, USA
Evol Dev 8:511-23. 2006..We conclude that Bmp expression has been largely conserved in vertebrate tooth development over evolutionary time, and that loss of Bmp expression is correlated with region-specific loss of the dentition in a major group of fishes... - Transgenic analysis of Dlx regulation in fish tooth development reveals evolutionary retention of enhancer function despite organ lossWilliam R Jackman
Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO 80309, USA
Proc Natl Acad Sci U S A 103:19390-5. 2006..If enhancers of other genes in the tooth developmental pathway are similarly preserved, teeth lost from specific regions may be relatively easy to reacquire in evolution... - Development and evolution of craniofacial patterning is mediated by eye-dependent and -independent processes in the cavefish AstyanaxYoshiyuki Yamamoto
Department of Biology, University of Maryland, College Park, MD 20742-4415, USA
Evol Dev 5:435-46. 2003..The results suggest that evolution of the cavefish craniofacial skeleton is controlled by multiple developmental events, some a direct consequence of eye degeneration and others unrelated to loss of the eye... - Zebrafish furin mutants reveal intricacies in regulating Endothelin1 signaling in craniofacial patterningMacie B Walker
Institute of Neuroscience, 1254 University of Oregon, Eugene, OR 97403, USA
Dev Biol 295:194-205. 2006.... - Zebrafish fgf24 functions with fgf8 to promote posterior mesodermal developmentBruce W Draper
Institute of Neuroscience, University of Oregon, Eugene, OR 97403, USA
Development 130:4639-54. 2003..Last, we show that fgf24 is expressed in early fin bud mesenchyme and that inhibiting fgf24 function results in viable fish that lack pectoral fins... - Genomic structure and functional control of the Dlx3-7 bigene clusterKenta Sumiyama
Department of Molecular, Cellular, and Developmental Biology, Yale University, New Haven, CT 06511, USA
