Abstract

Passive immunization against inhibin with an anti-inhibin serum (AIS) during the diestrous phase in cycling rats increased follicle-stimulating hormone secretion, stimulated the ovaries and reduced the magnitude of the luteinizing hormone (LH) surge in the afternoon of proestrus. The involvement of gonadotrope progesterone receptor (PR) expression/action in the inhibitory effects of the follicle-stimulating hormone-dependent putative ovarian factor gonadotropin surge-attenuating factor on preovulatory LH secretion was studied in the absence of circulating free inhibin. Proestrous pituitaries from rats injected with AIS or a non-immune serum (NIS) were studied for determination of PR-AB and PR-B mRNAs by RT-PCR and PR-B and PR-A isoform proteins by Western blot. In addition, pituitaries from AIS- and NIS-injected rats were incubated and studied for PR-dependent LH secretion parameters: LH-releasing hormone (LHRH)-stimulated LH secretion, progesterone-potentiated LHRH-stimulated LH secretion and LHRH self-priming. Also, the effects of the antiprogestagen RU486 on these LH secretion parameters were evaluated and compared with those of AIS. Finally, gonadotrope PR phosphorylation was evaluated by immunohistochemistry. Results showed that the hyperstimulated ovaries of AIS-injected rats produce a factor, different from inhibin, that blocked LHRH self-priming and P-potentiation of LHRH-stimulated LH secretion. These effects were not due to decreased pituitary PR mRNAs, PR protein expression or PR protein B/A ratio. The inhibitory effect of AIS on PR-dependent LH secretion seemed to be due to gonadotrope PR dephosphorylation. Taken together, the findings indicated that the putative gonadotropin surge-attenuating factor affected LH surge through an inhibition of PR phosphorylation/action but not PR expression.
