Oral cortisol and dexamethasone intake: Differential physiology and transcripti...
Barany, A.; Fuentes, Juan; Valderrama, V.; Broz-Ruiz, A.; Martínez-Rodríguez, G.; Mancera, J. M.This study approached the long-term oral administration of cortisol (F) and dexamethasone (DEX), two synthetic glucocorticoids, compared to a control group (CT) in the juveniles of a marine teleost, the gilthead seabream (Sparus aurata). Physiologically, DEX treatment impaired growth, which appears to be linked to carbohydrate allocation in muscle and liver, hepatic triglycerides depletion, and reduced hematocr...

Tissue and salinity specific Na+/Cl− cotransporter (NCC) orthologues involved i...
Barany, A.; Shaughnessy, C. A.; Pelis, R. M.; Fuentes, J.; Mancera, J. M.; McCormick, S. D.Two orthologues of the gene encoding the Na+-Cl− cotransporter (NCC), termed ncca and nccb, were found in the sea lamprey genome. No gene encoding the Na+-K+-2Cl cotransporter 2 (nkcc2) was identifed. In a phylogenetic comparison among other vertebrate NCC and NKCC sequences, the sea lamprey NCCs occupied basal positions within the NCC clades. In freshwater, ncca mRNA was found only in the gill and nccb only in...
Dietary aflatoxin B1 (AFB1) reduces growth performance, impacting growth axis, ...
Barany, A.; Guilloto, M.; Cosano, J.; de Boevre, M.; Oliva, M.; de Saeger, S.; Fuentes, J.; Martinez-Rodriguez, G.; Mancera, J. M.Mycotoxins are an increasing threat to all the related commodities from agriculture. Its occurrence is expected to increase due to climate change. Here, we examined the impacts of dietary toxicity of aflatoxin B1 (AFB1) in gilthead sea bream (Sparus aurata) at levels of 1 or 2 mg AFB1 kg(-1)- fish feed. Inclusion of AFB1 in the diet resulted in 80% inhibition of the total weight gain during the 85-day trial. Ca...
Low dietary inclusion of nutraceuticals from microalgae improves feed efficienc...
Perera, Erick; Sánchez-Ruiz, David; Sáez, María Isabel; Galafat, Alba; Barany, A.; Fernández-Castro, Miriam; Vizcaíno, Antonio Jesús; Fuentes, JuanThe aim of this work was to evaluate two functional feeds for the gilthead seabream, Sparus aurata, containing low inclusion of two microalgae-based products (LB-GREENboost, LBGb; and LB-GUThealth, LBGh). Fish (12-13 g) were fed for 13 weeks a control diet or one of the four diets supplemented with both products at 0.5% or 1%. LBGb and LBGh did not affect specific growth rate or survival, but increased feed eff...
Intestinal response to salinity challenge in the Senegalese sole (Solea senegal...
Ruiz-Jarabo, I.; Barany, A.; Jerez-Cepa, I.; Mancera, J. M.; Fuentes, JuanFish are continuously forced to actively absorb or expel water and ions through epithelia. Most studies have focused on the gill due to its role in Na+ and Cl- trafficking. However, comparatively few studies have focused on the changing function of the intestine in response to external salinity. Therefore, the present study investigated the main intestinal changes of long-term acclimation of the Senegalese sole...
