Central clock regulates the cervically stimulated prolactin surges by modulation of dopamine and vasoactive intestinal polypeptide release in ovariectomized rats.

abstract：:We have previously shown that the diterpene forskolin, a compound which increases intracellular cyclic AMP (cAMP), causes a concentration-dependent release of luteinizing hormone (LH) by continuously perifused anterior pituitary cells from female rats. To test the hypothesis that cAMP-associated LH release is an estro...
