Silvering (transition from yellow to silver eel) has been traditionally considered as a metamorphosis in view of the numerous morphological, physiological and behavioral changes preparing eel for oceanic migration. However, some changes, such increases gonad weight steroidogenesis, suggest that silvering could also be pubertal event. In order assess which endocrine axis may involved induction silvering, we compared profiles pituitary peripheral hormones during transition female eels. A...
Pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating (FSH) are, in teleosts as mammals, under the control of hypothalamic factors steroid feedbacks. In teleosts, feedback regulations largely vary depending on species physiological stage. present study regulation FSH LH expression was investigated European eel, a fish biological phylogenetical interest representative an early group teleosts. The eel FSHβ subunit cloned, sequenced together with earlier isolated LHβ...
Corticotropin-releasing hormone (CRH) was discovered for its role as a brain neurohormone controlling the corticotropic axis in vertebrates. An additional crh gene, crh2, paralog of (crh1), and likely resulting from second round (2R) vertebrate whole genome duplication (WGD), identified holocephalan chondrichthyan, basal mammals, various sauropsids non-teleost actinopterygian holostean. It suggested that crh2 has been recurrently lost some groups including teleosts. We further investigated...
The widespread use of 17α-ethinylestradiol (EE2), and other estrogenic endocrine disruptors, results in a continuous release compounds into aquatic environments. Xenoestrogens may interfere with the neuroendocrine system organisms produce various adverse effects. aim present study was to expose European sea bass larvae (Dicentrarchus labrax) EE2 (0.5 50 nM) for 8 d determine expression levels brain aromatase (cyp19a1b), gonadotropin-releasing hormones (gnrh1, gnrh2, gnrh3), kisspeptins...
