Abstract
The present work is part of a broad phylogenetic study of the insulin superfamily of peptides in lower vertebrates. In the bony fish barramu ndi (Lates calcarifer), the presence of IGF receptors were investigate d in the liver by means of competitive binding studies. The results su ggested the presence of a type 1-like but no type 2-like IGF receptor. We also demonstrated insulin-like effects of intraperitoneally inject ed recombinant human (rh)-IGF-1 in barramundi with rh-ICF-l and rh-ins ulin showing similar effects with respect to induction of hypoglycemia and stimulation of incorporation of [C-14]-glucose into muscle glycog en.
