Ectodysplasin, Edar and TNFRSF19 are expressed in complementary and overlapping patterns during mouse embryogenesisJohanna Pispa
Developmental Biology Programme, Institute of Biotechnology, Viikki Biocenter, University of Helsinki, 00014, Helsinki, Finland
Gene Expr Patterns 3:675-9. 2003..We also studied the expression pattern of a related TNF receptor, TNFRSF19, and show that it is expressed in an overlapping domain with Edar in the tooth, mammary gland, whiskers, and limb bud suggesting a potentially redundant role...- Cusp patterning defect in Tabby mouse teeth and its partial rescue by FGFJ Pispa
Institute of Biotechnology, Viikki Biocenter, University of Helsinki, Finland
Dev Biol 216:521-34. 1999..Instead FGF-10 partially restored morphogenesis and stimulated the development of additional tooth cusps in cultured Tabby molars... - Signaling and subcellular localization of the TNF receptor EdarP Koppinen
Developmental Biology Program, University of Helsinki, Helsinki, 00014, Finland
Exp Cell Res 269:180-92. 2001..This together with differences in NF-kappaB responses suggests an explanation for the different mode of inheritance of the different downless alleles... - TNF signaling via the ligand-receptor pair ectodysplasin and edar controls the function of epithelial signaling centers and is regulated by Wnt and activin during tooth organogenesisJ Laurikkala

Dev Biol 229:443-55. 2001..This is the first demonstration of integration of the Wnt, activin, and TNF signaling pathways... - Ectodysplasin, a protein required for epithelial morphogenesis, is a novel TNF homologue and promotes cell-matrix adhesionM L Mikkola
Developmental Biology Program, Institute of Biotechnology, Viikki Biocenter, 00014 University of Helsinki, Helsinki, Finland
Mech Dev 88:133-46. 1999..Ectodysplasin is the first TNF-like signaling molecule described known to be required for epithelial morphogenesis... - The anhidrotic ectodermal dysplasia gene (EDA) undergoes alternative splicing and encodes ectodysplasin-A with deletion mutations in collagenous repeatsM Bayes
Department of Medical Genetics, Haartman Institute, PO Box 21, University of Helsinki, 00014 Helsinki, Finland

Developmental Biology Program, Institute of Biotechnology, Viikki Biocenter, University of Helsinki, 00014 Helsinki, Finland
Dev Biol 259:123-36. 2003..We conclude that ectodysplasin-Edar signaling has several roles in ectodermal organ development controlling their initiation, as well as morphogenesis and differentiation... - Regulation of hair follicle development by the TNF signal ectodysplasin and its receptor EdarJohanna Laurikkala
Institute of Biotechnology, Viikki Biocenter, 00014 University of Helsinki, Finland
Development 129:2541-53. 2002..In conclusion, we suggest that Eda and Edar are associated with the onset of ectodermal patterning and that ectodysplasin/edar signaling also regulates the morphogenesis of hair follicles... - Tooth patterning and enamel formation can be manipulated by misexpression of TNF receptor EdarJohanna Pispa
Developmental Biology Programme, Institute of Biotechnology, Viikki Biocenter, University of Helsinki, Helsinki, Finland
Dev Dyn 231:432-40. 2004..In addition, tooth enamel formation is defective in a dose-dependent manner. We speculate that the tooth patterning defects are caused by ectopic Edar activity outside the signaling centers... - Ectodysplasin A1 promotes placodal cell fate during early morphogenesis of ectodermal appendagesTuija Mustonen
Developmental Biology Program, Institute of Biotechnology, PO Box 56 Viikinkaari 9, University of Helsinki, Finland
Development 131:4907-19. 2004..Taken together, our results suggest that Eda-A1 signalling promotes placodal cell fate during early development of ectodermal organs... - Drosophila non-muscle alpha-actinin is localized in nurse cell actin bundles and ring canals, but is not required for fertilityGudrun Wahlström
Developmental Biology Program Institute of Biotechnology, Viikki Biocenter, P O Box 56 Viikinkaari 9, FIN 00014, University of Helsinki, Finland
Mech Dev 121:1377-91. 2004..We also show that ectopically expressed adult muscle-specific alpha-actinin localizes to all F-actin containing structures in the nurse cells in the absence of endogenous non-muscle alpha-actinin...

Cellular Biotechnology Research Program, Institute of Biotechnology, University of Helsinki, Finland
BMC Dev Biol 8:51. 2008..While the fungal orthologues of Dss1 are not essential for viability, the significance of Dss1 in metazoans has remained unknown due to a lack of knockout animal models...- Mechanisms of ectodermal organogenesisJohanna Pispa
Developmental Biology Programme, Institute of Biotechnology, Viikki Biocenter, University of Helsinki, 00014, Helsinki, Finland
Dev Biol 262:195-205. 2003..Here the current knowledge on the molecular regulation of the initiation, placode formation, and morphogenesis of ectodermal organs is discussed with emphasis on feathers, hair, and teeth... - Transgenic mouse models support HCR as an effector gene in the PSORS1 locusOuti Elomaa
Department of Medical Genetics, University of Helsinki, Helsinki University Central Hospital, Finland
Hum Mol Genet 13:1551-61. 2004..These observations are also compatible with a model that a susceptibility gene for psoriasis induces changes that are contributory but not sufficient by itself to produce the clinical phenotype...
