[The growth-stimulating activity of the insulins from teleosts]

Growth-stimulating properties of insulins from cyclostomes, teleosts and mammals were evaluated by their capacity to promote the uptake of [35S]-sulfate by fish branchial cartilages. It was shown that all the tested hormones exhibit promotor properties increasing the uptake of labeled sulfate by 1.5-3 times. The effects depend both on the dose of the hormone and on peculiarities of its molecular structure.
