摘要

本研究的目的是检测兔肌膜中腺苷酸环化酶(AC)的活性及其被camp依赖蛋白激酶(PKA)磷酸化的情况。异丙肾上腺素(IP)可显著提高未妊娠家兔肌层质膜AC活性。然而,在怀孕期间,肌膜质膜AC对IP没有反应。PKA使肌膜磷酸化后,AC对IP的反应显著降低。

Adenylate cyclase of myometrium and its regulation by cAMP-dependent protein kinase.
The purpose of this study was to examine activity of adenylate cyclase (AC) and its cAMP-dependent phosphorylation by cAMP-dependent protein kinase (PKA) in the membrane of rabbit myometrium. Isoproterenol (IP) significantly increased AC activity of nonpregnant rabbits myometrium plasma membranes. However, during pregnancy AC of myometrium plasma membranes did not respond to IP. Phosphorylation of the myometrium membrane by PKA was followed by significantly decreased response of AC to IP.
