Thermal imprinting modifies adult stress and innate immune responsiveness in th...
Mateus, Ana; A Costa, Rita; Cardoso, João CR; Andree, Karl B.; Estevez, Alicia; Gisbert, Enric; Power, DeborahThe impact of thermal imprinting on the plasticity of the hypothalamic-pituitary-interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparus aurata, L.), during its development was assessed. Fish were reared under 4 thermal regimes, and the resulting adults exposed to acute confinement stress and plasma cortisol levels and genes of the HPI axis were monitored. Changes in immu...
Thermal imprinting modifies bone homeostasis in cold-challenged sea bream (Spar...
Mateus, Ana; Costa, Rita; Gisbert, Enric; PI Pinto, PPinto; Andree, Karl B.; Estevez, Alicia; Power, DeborahFish are ectotherms and temperature plays a determinant role in their physiology, biology and ecology, and is a driver of seasonal responses. The present study assessed how thermal imprinting during embryonic and larval stages modified the response of adult fish to low water temperature. We targeted the gilthead sea bream, which develops a condition known as winter syndrome when it is exposed to low water tempe...
Vitamin A affects flatfish development in a thyroid hormone signaling and metam...
Fernandez, Ignacio; Ortiz-Delgado, Juan B.; Darias, Maria J.; Hontoria, Francisco; Andree, Karl B.; Manchado, Manuel; Sarasquete, Carmen; Gisbert, EnricVitamin A (VA) and retinoid derivatives are known morphogens controlling vertebrate development. Despite the research effort conducted during the last decade, the precise mechanism of how VA induces post-natal bone changes, and particularly those operating through crosstalk with the thyroid hormones (THs) remain to be fully understood. Since effects and mechanisms seem to be dose and time-dependent, flatfish ar...
Coordinated regulation of chromatophore differentiation and melanogenesis durin...
Darias, Maria J.; Andree, Karl B.; Boglino, Anais; Fernandez, Ignacio; Estevez, Alicia; Gisbert, EnricAbnormal pigmentation of Senegalese sole has been described as one problem facing the full exploitation of its commercial production. To improve our understanding of flatfish pigmentation of this commercially important species we have evaluated eleven genes related to two different processes of pigmentation: melanophore differentiation, and melanin production. The temporal distribution of gene expression peaks ...
