Abstract
We have demonstrated that the novel hypothalamic peptide pituitary adenylate cyclase-activating poly-peptide (PACAP-38; 0·1–100 nmol/l) caused an increase in the release of GH, ACTH, LH and α-subunit and accumulation of intracellular cyclic AMP from dispersed rat anterior pituitary cells in static culture for 24 h. There were no significant effects on TSH or prolactin release over the same time-period. PACAP-38 (10 nmol/l) increased the release of GH by 1·3-fold (PPPP< 0·005) and the accumulation of intracellular cyclic AMP by >2-fold (PJournal of Endocrinology (1992) 134, 33–41Keywords
