N2 - Immunocytochemical detection of androgen receptors (ARs) in several compartments of the macaque ovary, including the germinal epithelium, follicle, and corpus luteum, suggests a role for androgens in modulating ovarian function via the classical receptor-mediated pathway. To examine AR mRNA expression in the rhesus monkey ovary, total RNA was isolated from whole ovaries, the germinal epithelium-enriched cortical and medullary compartments of the ovary, and corpora lutea from early (d 3-5), mid (d 6-8), mid-late (d 10-12), and late (d 13-15) stages of the luteal phase of the menstrual cycle. RNA was also obtained from luteinized granulosa cells from monkeys receiving gonadotropin treatment to stimulate the development of multiple ovarian follicles. After reverse transcription of total RNA using oligo-dT as a primer, polymerase chain reaction (PCR) was used to amplify a unique 329 bp segment of the monkey AR hormone-binding region. Reverse transcriptase (RT)- PCR products of the expected size were detected in all ovarian and control tissues. Sequence analysis of the AR cDNA from the macaque ovary revealed 99% nucleotide homology and 100% predicted amino acid homology to the cDNA for the hormone-binding region of human AR. Northern analysis demonstrated the presence of a major AR mRNA species at 9.5 kb in corpus luteum, luteinized granulosa cells, and prostate, with additional bands detected in the corpus luteum and prostate at 7.9 and 3.4 kb, respectively. A sensitive RNase protection assay was used to examine AR mRNA levels in ovarian tissues and showed AR mRNA expression throughout the life-span of the corpus luteum. Thus, detection of AR mRNA in the primate ovary, including the periovulatory follicle and corpus luteum, supports the concept that these tissues are targets for receptor-mediated androgen action during the menstrual cycle.
