Testosterone, progesterone, and estradiol-17 beta each inhibit cAMP phosphodiesterase activity of mouse oocyte extracts in a concentration-dependent manner. This finding provides an explanation for the inhibitory effect of steroid hormones on germinal vesicle breakdown (GVBD) of mouse oocytes in vitro. Furthermore, it raises the possibility that steroid hormones present in follicular fluid participate in maintaining meiotic arrest in vivo by acting in a nonclassical manner.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D009865 Oocytes Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM). Ovocytes,Oocyte,Ovocyte
D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS. Pregnenedione,Progesterone, (13 alpha,17 alpha)-(+-)-Isomer,Progesterone, (17 alpha)-Isomer,Progesterone, (9 beta,10 alpha)-Isomer
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D004958 Estradiol The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids. 17 beta-Estradiol,Estradiol-17 beta,Oestradiol,17 beta-Oestradiol,Aerodiol,Delestrogen,Estrace,Estraderm TTS,Estradiol Anhydrous,Estradiol Hemihydrate,Estradiol Hemihydrate, (17 alpha)-Isomer,Estradiol Monohydrate,Estradiol Valerate,Estradiol Valeriante,Estradiol, (+-)-Isomer,Estradiol, (-)-Isomer,Estradiol, (16 alpha,17 alpha)-Isomer,Estradiol, (16 alpha,17 beta)-Isomer,Estradiol, (17-alpha)-Isomer,Estradiol, (8 alpha,17 beta)-(+-)-Isomer,Estradiol, (8 alpha,17 beta)-Isomer,Estradiol, (9 beta,17 alpha)-Isomer,Estradiol, (9 beta,17 beta)-Isomer,Estradiol, Monosodium Salt,Estradiol, Sodium Salt,Estradiol-17 alpha,Estradiol-17beta,Ovocyclin,Progynon-Depot,Progynova,Vivelle,17 beta Estradiol,17 beta Oestradiol,Estradiol 17 alpha,Estradiol 17 beta,Estradiol 17beta,Progynon Depot

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013739 Testosterone A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL. 17-beta-Hydroxy-4-Androsten-3-one,17-beta-Hydroxy-8 alpha-4-Androsten-3-one,8-Isotestosterone,AndroGel,Androderm,Andropatch,Androtop,Histerone,Sterotate,Sustanon,Testim,Testoderm,Testolin,Testopel,Testosterone Sulfate,17 beta Hydroxy 4 Androsten 3 one,17 beta Hydroxy 8 alpha 4 Androsten 3 one,8 Isotestosterone
D015105 3',5'-Cyclic-AMP Phosphodiesterases Enzymes that catalyze the hydrolysis of CYCLIC AMP to form adenosine 5'-phosphate. The enzymes are widely distributed in animal tissue and control the level of intracellular cyclic AMP. Many specific enzymes classified under this heading demonstrate additional spcificity for 3',5'-cyclic IMP and CYCLIC GMP. 3',5'-Cyclic AMP 5'-Nucleotidohydrolase,3',5'-Cyclic-Nucleotide Phosphodiesterase,CAMP Phosphodiesterase,3',5' Cyclic AMP Phosphodiesterase,3',5'-Cyclic AMP Phosphodiesterase,3',5'-Cyclic Nucleotide Phosphodiesterase,3',5'-Cyclic-AMP Phosphodiesterase,3',5'-Nucleotide Phosphodiesterase,3,5-Cyclic AMP 5-Nucleotidohydrolase,3,5-Cyclic AMP Phosphodiesterase,3',5' Cyclic AMP 5' Nucleotidohydrolase,3',5' Cyclic AMP Phosphodiesterases,3',5' Cyclic Nucleotide Phosphodiesterase,3',5' Nucleotide Phosphodiesterase,3,5 Cyclic AMP 5 Nucleotidohydrolase,3,5 Cyclic AMP Phosphodiesterase,5'-Nucleotidohydrolase, 3',5'-Cyclic AMP,5-Nucleotidohydrolase, 3,5-Cyclic AMP,AMP 5'-Nucleotidohydrolase, 3',5'-Cyclic,AMP 5-Nucleotidohydrolase, 3,5-Cyclic,AMP Phosphodiesterase, 3',5'-Cyclic,AMP Phosphodiesterase, 3,5-Cyclic,Nucleotide Phosphodiesterase, 3',5'-Cyclic,Phosphodiesterase, 3',5'-Cyclic AMP,Phosphodiesterase, 3',5'-Cyclic Nucleotide,Phosphodiesterase, 3',5'-Cyclic-AMP,Phosphodiesterase, 3',5'-Cyclic-Nucleotide,Phosphodiesterase, 3',5'-Nucleotide,Phosphodiesterase, 3,5-Cyclic AMP,Phosphodiesterase, CAMP,Phosphodiesterases, 3',5'-Cyclic-AMP
