Abstract
Experiments are reported showing that following 8 days of denervation the function of the protein-synthesizing machinery, operating in the rat gastrocnemius fibres, is altered, probably as a consequence of decreased amounts of ribosomes and actively translated mRNA. In addition, the data obtained show that the amount per muscle and the availability per ribosome of the soluble factors involved in the process of protein synthesis are markedly decreased, thus suggesting that the amounts of ribosomes, mRNA and soluble factors are regulated in a concerted fashion when muscular protein synthesis is decreased after denervation.
