The effect of prostaglandins E1, E2 and F2 alpha and indomethacin on the sensitivity of glycolysis and glycogen synthesis to insulin in stripped soleus muscles of the rat.

Prostaglandins E1 and E2 increased the sensitivity of glycolysis to insulin in the isolated stripped soleus muscle of the rat, but prostaglandin F2 alpha had no effect. Indomethacin, which inhibits prostaglandin formation, markedly decreased the sensitivity of glycolysis to insulin. These findings suggest that prostaglandins of the E series increase the sensitivity of muscle glycolysis to insulin in vivo.
