[Skeletal muscle nuclear ATPase under denervation].
Denervation of the rabbit gastrocnemius muscle is shown to result after 18 and 72 h in a decrease of Mg2+-, Ca2+-dependent and an increase of Mg+-dependent parts of nuclear ATPase activity, with the total level of the enzyme activity retained. 7 days later the total ATPase activity of nuclei decreases as well as the expense of its EGTA-dependent part. These changes correlate with those in the nuclear Ca total content. Indirect electrostimulation of the denervated muscle increase both the 7g2+-, Ca2+-dependent ATPase activity and the Ca content in nuclei. Tenotomy for 18 h does not change these parameters.
