Prolactin, a Factor in Promoting Survival of Hypophysectomized Killifish in Fresh Water
TLDR
The naturally occurring corticosteroids, cortisol and aldosterone, failed to promote survival of hypophysectomized Fundulus heteroclitus in fresh water, and highly purified prolactin maintained survival, although the recipients did not eat normally.

TLDR
The data suggest that this enzyme is involved in the excretion of sodiumions by the gill and that the adaptive increase which occurs in seawater is influenced by the hypophysis.

Branchial Reduction and Renal Stimulation of (Na+, K+)-ATPase by Prolactin in Hypophysectomized Killifish in Fresh Water
TLDR
Maetz and his associates have shown that a primary osmoregulatory function of prolactin is the reduction of extrarenal sodium outflux which is uncontrolled, or poorly controlled, after removal of the hypophysis.

TLDR
Freshwater stingrays are unique among elasmobranchs in possessing significant amounts of a protein with the electrophoretic mobility of human mobility, and the trend to increase in a saline environment was not osmotically significant.
