Abstract
The ureogenic effect of glucagon in the rat in vivo was accompanied by a decrease in the rate of hepatic protein synthesis and by a significant and progressive increase of proteolysis, expressed as a rise in hepatic valine levels. The effect on protein synthesis was maximal five minutes after hormone administration and decreased progressively thereafter to reach control values after 20 minutes. On the contrary, ureogenesis and proteolysis increased progressively throughout the 20 minutes of the experiment suggesting a close relationship between the two processes.
