Cloning and expression of three aquaporin homologues from the European eel (<i>Anguilla anguilla</i>): effects of seawater acclimation and cortisol treatment on renal expression

Abstract

These results suggest that SW-acclimation or cortisol infusion induces a down-regulation of renal AQP expression in yellow eels. However, the lower levels of aquaporin expression found within the silver eel kidney were not further reduced by salinity transfer or steroid infusion. These differences in mRNA expression were accompanied by changes in the cellular distribution of the AQP1 protein between vascular endothelial and tubular epithelial cells.
