Article Synopsis
  • - Atlantic salmon need to drink seawater to maintain body hydration, and the esophagus helps by desalinating this water for absorption in the intestines.
  • - The study focused on two Na/H exchangers (Nhe2 and Nhe3) in the esophagus and found that while Nhe3 expression increased after 48 hours in seawater, there were no changes during the seasonal smoltification process.
  • - Cortisol plays a key role in enhancing the function of ion transporters in the esophagus and intestines, helping salmon adapt to seawater by modulating the expression of important genes involved in salt absorption.

Prolactin (Prl) was identified over 60 years ago in mummichogs (Fundulus heteroclitus) as a "freshwater (FW)-adapting hormone", yet the cellular and molecular targets of Prl in this model teleost have remained unknown. Here, we conducted a phylogenetic analysis of two mummichog Prl receptors (Prlrs), designated Prlra and Prlrb, prior to describing the tissue- and salinity-dependent expression of their associated mRNAs. We then administered ovine Prl (oPrl) to mummichogs held in brackish water and characterized the expression of genes associated with FW- and seawater (SW)-type ionocytes.
