Cortisol Regulates Acid Secretion of H+-ATPase-rich Ionocytes in Zebrafish (Danio rerio) Embryos
Systemic acid-base regulation is vital for physiological processes in vertebrates. Freshwater (FW) fish live in an inconstant environment, and thus frequently face ambient acid stress. FW fish have to efficiently modulate their acid secretion processes for body fluid acid-base homeostasis during ambient acid challenge; hormonal control plays an important role in such physiological regulation. T...
متن کاملIon uptake and acid secretion in zebrafish (Danio rerio).
Transepithelial transport is one of the major processes involved in the mechanism of homeostasis of body fluids in vertebrates including fish. The current models of ion regulation in fish gill ionocytes have been proposed mainly based on studies in traditional model species like salmon, trout, tilapia, eel and killifish, but the mechanisms are still being debated due to the lack of convincing m...
متن کاملDevelopmental toxicity of nonylphenol in zebrafish (Danio rerio) embryos
Present study reports the response of zebrafish embryos exposed in vivo to graded concentrations of Nonylphenol (NP), ranging from high lethal levels to lower, more environmentally relevant levels. Embryos treated with NP showing developmental abnormalities and morphological alterations in a dose-dependent pattern. Results suggest that early exposure to NP can cause direct and delayed mortaliti...
متن کاملDanio Rerio, the Zebrafish
The zebrafish has long been a favourite model for the study of vertebrate development. Here we provide an overview of the current state of knowledge and resources for the study of this fish, with comments on the future direction of zebrafish genomics from Professor Mark Fishman and Dr Stephen Wilson.
متن کاملKnockdown of V-ATPase subunit A (atp6v1a) impairs acid secretion and ion balance in zebrafish (Danio rerio).
In the skin of zebrafish embryo, the vacuolar H(+)-ATPase (V-ATPase, H(+) pump) distributed mainly in the apical membrane of H(+)-pump-rich cells, which pump internal acid out of the embryo and function similarly to acid-secreting intercalated cells in mammalian kidney. In addition to acid excretion, the electrogenic H(+) efflux via the H(+)-ATPases in the gill apical membrane of freshwater fis...
