In vivo and in vitro effects of growth hormone on the incorporation of ( UC)leucine into protein of liver and muscle of the eel

Journal Article · · Gen. Comp. Endocrinol.; (United States)
In vivo administration of ovine GH (2 micrograms/g body wt) increased ( UC)leucine incorporation into protein of the liver, skeletal muscle, and opercular muscle of hypophysectomized eels. Addition of ovine GH into the medium slightly increased ( UC)leucine incorporation into protein of liver slices during 5 hr in vitro incubation, but did not affect protein synthesis from ( UC)leucine in opercular muscle. In vivo pretreatment with ovine GH 48 hr prior to tissue preparation clearly increased ( UC)leucine incorporation into protein of liver slices in vitro. However, no statistically significant change was observed for in vitro incorporation of ( UC)leucine into protein of opercular muscle of hypophysectomized eels which had been previously treated with ovine GH. These results indicate that ovine GH has a protein anabolic action in the liver and muscle of the eel and that compared to mammals a rather long lag period is needed to elicit such protein anabolic actions of GH in these animals.
