Functional studies of <i>Ci-Gsx</i> gene in the developing central nervous system of <i>Ciona intestinalis</i>
… of the vertebrate neural rube. In the ascidian Ciona inlesrinalis, the model organism used in this work, a single Gsx ortholog has been identified, named Ci-gsx, whose zygotic expression is localized in the developing CNS, including the precursors of the ocellus photoreceptor cells. Clana …

DEVELOPMENT OF THE LARVAL PERIPHERAL NERVOUS SYSTEM IN THE ASCIDIAN CIONA INTESTINALIS: ROLE OF THE RETINOIC ACID AND FGF/WNT SIGNALLING PATHWAYS AND OF THE POU TRANSCRIPTION FACTORS.
… larval peripheral nervous system of the Tunicate Ciona intestinalis with two main aims: a) to understand how the interactions between Retinoic Acid (RA) and the FGF/WNT pathways control its development; b) to study the role played by transcription factors of the POU family in its differentiation. …

Eine phylogenetische Analyse von Serpin-Genen aus eukaryotischen Genomprojekten
… melanogaster, Arabidopsis thaliana und Ciona intestinalis erstellt, die auf mehreren unabhängigen Kriterien basieren. Neben den Aminosäuresequenzen wurden auch die chromosomalen Lokalisationen und die Genstrukturen zur phylogenetischen Klassifikation der Serpine eingesetzt. Dazu wurden …

Étude comparative des conditions environnementales potentiellement limitantes dans l'établissement d'une espèce aquatique envahissante Ciona intestinalis (Linnaeus, 1767) dans deux systèmes de bassins versants à l'Île-du-Prince-Edouard, Canada
"L'objectif de cette recherche consiste à identifier et à comprendre les principaux facteurs clés, qui pourraient potentiellement limiter l'établissement d'une espèce de tunicier à l'Î.-P.-É."--feuille v.

Evolutionary and Developmental Survey of Genes Involved in Chordate Pigmentation
… I analyzed a Kelch-like member in ascidian <i>Ciona robusta</i> (<i>Cr-Klhl21</i>). My results point at this gene as a marker of pigmented cells, with a dynamic expression profile during embryogenesis: from middle tailbud stage, it is expressed specifically in the otolith. Moreover, …

MODELING INFERTILITY: SINGLE GENE MUTATIONS AND CONSEQUENCES FOR GERM CELL DEVELOPMENT
… mice and for zygotic genome activation (ZGA) in Ciona intestinalis. In humans, CCNB3 mutations cause recurrent pregnancy loss. We explored meiotic and post-meiotic roles of CCNB3 using imaging studies, fertility tests, and pronuclei swap experiments. Ccnb3-/- females are sterile. Ccnb3-/- oocytes …

Exploring the functional conservation of muscleblind (Mbl) proteins
… Trichoplax adhaerens, a primitive chordate, Ciona intestinalis, and the model organisms, Drosophila melanogaster and Caenorhabditis elegans were compared to human Muscleblind-like (MBNL). The zinc finger RNA-binding domains are the most conserved region between homologs, suggesting a …

Phylogenomics of vertebrate serpins
… vectensis, Strongylocentrotus purpuratus, Ciona intestinalis, four fish species, frog, chicken and mammals were investigated, using gene architecture analyses and stringent criteria for identification of orthologs. With some deviations, all vertebrate serpin genes fit into one of the six …

EMISSIVE PEPTIDE NUCLEIC ACIDS (PNAS): POTENTIAL TOOLS FOR INNOVATIVE DIAGNOSTICS AND THERAPEUTICS
… effects on the neural development of ascidian Ciona intestinalis embryos, in collaboration with Dr. Hitoyoshi (Laboratoire de Biologie du Développement de Villefranche-sur-mer, Sorbonne Université). By using this approach, it would be possible to investigate how miRNA-124 regulation could …

Use of genetic methods for determining patterns and processes during marine biological invasions
Invasive species are widely recognised as one of the major threats to marine biodiversity worldwide. With increasingly faster and more frequent transoceanic shipping, propagule pressure in the marine environment is likely to further increase, leading to a need for effective strategies for the early …
