Glucose overload in yolk has little effect on the long-term modulation of carbo...
Rocha, Filipa; Dias, J.; Engrola, S.; Gavaia, Paulo J.; Geurden, Inge; Dinis, Maria Teresa; Panserat, S.The use of early nutritional stimuli to program metabolic pathways in fish is ill defined. Therefore, studies were undertaken with zebrafish to assess the effect of high glucose levels during the embryonic stage as a lifelong modulator of genes involved in carbohydrate metabolism. Genes related to carbohydrate metabolism were expressed at low levels at 0.2 and 1 day post-fertilization (dpf). However, from 4 dpf...
Programming the metabolic gene expression in zebrafish juveniles (Danio rerio) ...
Rocha, F.; Dias, J.; Engrola, S.; Gavaia, Paulo J.; Geurden, Inge; Dinis, Maria Teresa; Panserat, S.Using zebrafish as a model organism, assess the effect of high glucose levels during early embryonic stages as a lifelong moderator of metabolic pathways.
Tolerance of zebrafish embryos to supra-physiologic yolk levels of glucose
Rocha, F.; Dias, J.; Engrola, S.; Gavaia, Paulo J.; Dinis, Maria Teresa; Panserat, S.Once spawned and fertilized the oviparous fish eggs operate as closed systems; only respiratory gases, heat and negligible amounts of solutes and water are exchanged freely, as a result of an extremely low permeability of the egg surface membranes. Currently, the opportunities to exert a nutritional stimulus during a stage of high metabolic plasticity, such as fish embryogenesis, are restricted to maternal tran...
