pubmed:abstractText |
Studies of the development of parasympathetic responsiveness in embryonic chick hearts have demonstrated that between days 2.5 and 10 in ovo the ability of muscarinic agonists to inhibit adenylate cyclase activity increases 10-fold in parallel with a 2.7-fold increase in the level of alpha i and alpha o. Thus, muscarinic inhibition of adenylate cyclase increases in parallel with an increase in alpha o and alpha i. These data suggest that changes in levels of guanine nucleotide regulatory proteins control, at least in part, the appearance of a parasympathetic response in the heart during embryonic development of the chick.
