Abstract/OtherAbstract:
The effects of adrenocorticotropic hormone (ACTH), human chorionic gonadotropin (hCG) and prostaglandin E2 (PGE2) on the progesterone secretion of luteal cells from rats were studied. Corpora lutea were harvested on Day 6 of pseudopregnancy and digested by trypsin. Homogeneous suspensions of luteal cells were used for short-term incubation. ACTH, PGE2, and hCG were added to the medium and the changes in progesterone production were measured by radioimmunoassay (RIA). Furthermore, specific ACTH-binding sites of the luteal cell membrane were studied by Scatchard analysis. ACTH, PGE2 and hCG increased synthesis of progesterone, and the combination of hCG with ACTH or PGE2 further increased production of the hormone. The effect of ACTH could be prevented by indomethacin. These effect of ACTH seem to be connected with specific ACTH-binding sites of the luteal cell membrane and with increased production of PGE2.
