[Effects of prolactin on nucleo-proteic metabolism in gill epithelium of two euryhalin mullets, Chelon labrosus and Liza ramada during fresh-water adaptation (author's transL)].
Prolactin (PRL) treatment induced a decrease in DNA content in SW, -- an increase in FW 8 days, -- and no effect in FW 20 days fish. In "nuclear", "microsomal" and "supernatant" centrifugation fractions, RNA content was increased in SW, -- decreased in FW 8 days, by PRL treatment while a little increase was observed in FW 20 days fish with an increase of 14C leucine and 3H uridine incorporation. These results are discussed with reference to existence of two chloride-cell-types.
