Effects of insulin-like growth factor-I and cortisol on Na+, K+-ATPase expression in osmoregulatory tissues of brown trout (Salmo trutta).

Abstract

The effect of recombinant bovine IGF-I (rbIGF-I) on hypo-osmoregulatory ability and the effect of rbIGF-I and cortisol (F) alone and in combination on Na+,K+-ATPase expression in fresh water (FW) acclimated brown trout (Salmo trutta) were examined in two experiments. In Experiment 1, fish were given three injections of saline or 0.01 or 0.1 microgram rbIGF… (More)
