Switching of Na+, K+-ATPase isoforms by salinity and prolactin in the gill of a cichlid fish.


We identified and investigated the changes in expression of two gill Na(+), K(+)-ATPase α-subunit isoforms (α-1a and α-1b) in relationship with salinity acclimation in a cichlid fish, Mozambique tilapia. Transfer of freshwater (FW)-acclimated fish to seawater (SW) resulted in a marked reduction in α-1a expression within 24 h and a significant increase in… (More)
