Oreochromis mossambicus | expression of Na+, K+-ATPase alpha-subunit isoforms alpha-1a and alpha-1b in relationship with salinity acclimation. Transfer of freshwater acclimated fish to seawater results in a marked reduction in alpha-1a expression within 24 h and a significant increase in alpha-1b expression with maximum levels attained 7 days after the transfer. Transfer of seawater-acclimated fish to freshwater induces a marked increase in alpha-1a expression within 2 days, while alpha-1b expression decreases significantly after 14 days. Hypophysectomy results in a virtual shutdown of alpha-1a mRNA expression in both freshwater- and seawtaer-acclimated fish, whereas no significant effect is observed in alpha-1b expression. Replacement therapy by ovine prolactin fully restores alpha-1a expression in freshwater-acclimated fish, while cortisol has a modest, but significant, stimulatory effect on alpha-1a expression. The mRNA expression of fxyd-11, a regulatory Na+,K+-ATPase subunit,is transiently enhanced during both freshwater and seawater acclimation | additional information |
