...Raquel N. Lima; Dietmar Kültz SUMMARY The effects of salinity on chloride cells (CC) and Na + /K + -ATPase content in gill epithelium of euryhaline killifish Fundulus heteroclitus were analyzed using laser scanning cytometry (LSC) and tissue microarrays (TMAs). Salinity acclimations consisted...

... the amphipathic ligand-binding groove are highly conserved. F. heteroclitus 14-3-3.a mRNA expression is high in gill epithelium, moderate in intestine and brain, and low in gonads, white muscle and heart. Because 14-3-3 proteins are important molecular scaffolds and cofactors for phosphoproteins and signaling...

... by permeabilizing the basolateral membrane with amphotericin B, Cl − influxes which were driven by a concentration gradient were shown to depend on the presence of apical Na + and K + . On the basis of these observations, we propose that active and electrogenic absorption of NaCl across the gill epithelium...

In freshwater teleosts, Na + and Cl − are absorbed across the gill epithelium from the dilute external environment. This serves to counterbalance...
