title: Studies of growth hormone secretion VIII. Effects of alpha,beta-methylene-ATP on prostglandin induced GH release and cyclic AMP accumlation in rat anterior pituitary glands.
abstract: Alpha, beta-methylene-ATP, a competitive inhibitor of adenylate cyclase of liver and fat cell membrane preparations, caused a dose related inhibition of PGE1 and PGE2-induced cyclic AMP accumulation in rat anterior pituitary explants. At the same time, this ATP analog potentiated PGE1 and PGE2-promoted growth hormone secretion. The possible functional role of prostaglandins and cyclic nucleotides in the regulation of growth hormone secretion remains to be defined.
