Effects of Growth Hormone and Cortisol on Na � –K � – 2Cl � Cotransporter Localization and Abundance in the Gills of Atlantic Salmon
The hormones responsible for the regulation of the teleostean gill Na � –K � –2Cl � cotransporter have not been elucidated. With Western blotting and immunocytochemistry, Na � –K � –2Cl � cotransporter abundance and localization were examined in the gills of Atlantic salmon (Salmo salar) following 2...
