Effects of [D-Ala6,Des-Gly10]gonadotropin-releasing hormone (GnRH), ethylamide (GnRHa), and prostaglandin F2 alpha (PGF2 alpha) on inositol phosphate (IPs) formation and arachidonic acid (AA) release were studied in rat luteal cells of primary culture. In the cells obtained from one-day-old corpora lutea, PGF2 alpha (100 nM) and GnRHa (100 nM) significantly increased the IPs formation and the AA release. Antagonists of GnRH added solely or with GnRHa did not stimulate the IPs formation but did stimulate the AA release. In the cells obtained from 5-day-old corpora lutea, GnRHa failed to stimulate the IPs formation but significantly stimulated the AA release. The stimulation of both IPs formation and AA release by PGF2 alpha was consistently found in cells of two different luteal ages. These results suggest that GnRH receptor independently couples to both phospholipases C and A2 through different classes of GnRH receptors.
