Journal ArticleDOI
Control of puberty in farmed fish
Geir Lasse Taranger,Manuel Carrillo,Rüdiger W. Schulz,Pascal Fontaine,Silvia Zanuy,Alicia Felip,Finn-Arne Weltzien,Sylvie Dufour,Ørjan Karlsen,Birgitta Norberg,Eva Andersson,Tom Hansen +11 more
TL;DR: Puberty comprises the transition from an immature juvenile to a mature adult state of the reproductive system, i.e. the individual becomes capable of reproducing sexually for the first time, which implies functional competence of the brain-pituitary-gonad (BPG) axis.
Journal ArticleDOI
The brain-pituitary-gonad axis in male teleosts, with special emphasis on flatfish (Pleuronectiformes).
TL;DR: The present status on the male teleost BPG axis, with an emphasis on flatfish, is reviewed, and some entirely new information on the phylogeny and molecular structure of teleost gonadotropins is presented.
Journal ArticleDOI
Neuroendocrine control by dopamine of teleost reproduction
Sylvie Dufour,Marie-Emilie Sébert,Marie-Emilie Sébert,Finn-Arne Weltzien,Finn-Arne Weltzien,Karine Rousseau,Catherine Pasqualini +6 more
TL;DR: This work has shown that sex steroid feedbacks target DA hypophysiotropic system, as well as the other components of the brain-pituitary gonadotrophic axis, GnRH and gonADotrophins, which may have contributed to their large diversity of reproductive cycles.
Journal ArticleDOI
Dopaminergic Inhibition of Reproduction in Teleost Fishes: Ecophysiological and Evolutionary Implications
Sylvie Dufour,Finn-Arne Weltzien,Marie-Emilie Sébert,N. Le Belle,B. Vidal,Philippe Vernier,Catherine Pasqualini +6 more
TL;DR: DA inhibitory control could represent an ancient evolutionary component in the neuroendocrine regulation of reproduction that may have been differentially maintained throughout vertebrate evolution.
Journal ArticleDOI
Primitive duplicate Hox clusters in the European eel's genome.
Christiaan V. Henkel,Erik Burgerhout,Daniëlle L. de Wijze,Ron P. Dirks,Yuki Minegishi,Hans J. Jansen,Herman P. Spaink,Sylvie Dufour,Finn-Arne Weltzien,Katsumi Tsukamoto,Guido van den Thillart +10 more
TL;DR: It is shown that unlike any other teleost fish, the eel retains fully populated, duplicate Hox clusters, which originated at the teleost-specific genome duplication, and all copies are expressed in early embryos.
