Résumé :

Actinomycin D abolishes the post denervation increase in inorganic phosphate flow observed in the fast gastrocnemius muscle. In the slow soleus muscle, the initial decrease in phosphate flow is unaffected but the secondary rise is suppressed in the same manner as in the fast muscle. These observations put the post denervation increase in inorganic phosphate flow on a par with the development of extrajunctional cholinergic receptors in being the result of the synthesis of new proteins. It has the added advantage of being suitable to quantitative assessment at the whole muscle level.
