Oxytocin synthesis and release by the bovine corpus luteum

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...

Some ovarian characteristics of the postpartum rabbit

Creator:: Gjesvold, James Allen
Abstract:: The effects of suckling on several ovarian characteristics were studied in postpartum rabbits. Ovarian weight was found to be significantly greater in rabbits suckled for twelve days than in nonsuckled rabbits autopsied at a similar interval postpartum or in a third group autopsied at parturition. There were no significant differences...

Pituitary and uterine control of ovarian function in the gilt and ewe

Creator:: Chakraborty, Prabir Kumar, 1936-
Abstract:: The role of the pituitary gland and uterus in regulating ovarian function in the estradiol-treated gilt and ewe was investigated in two experiments. Pituitary gonadotropin content, ovarian follicular development and corpus luteum function were studied following daily intramuscular injection of seven gilts with 7 mg of 17β-estradiol from day 11...

Factors affecting prolactin secretion in the African elephant

Creator:: Bechert, Ursula S.
Abstract:: Prolactin (PRL) is a peptide hormone that is involved in a number of diverse physiologic roles, particularly with respect to reproduction, including: influencing sexual and parental behaviors, onset of puberty, regulation of seasonal reproduction, follicular maturation, ovulation, luteinization and corpus luteum (CL) function, steroidogenesis, mammary gland development and lactation, testicular...

Plasma membrane composition and luteinizing hormone receptors of ovine corpora lutea during early pregnancy

Creator:: Zelinski, Mary Beth
Abstract:: The lipid composition of plasma membranes of corpora lutea was examined to determine whether changes in this organelle occur during regression and early pregnancy in the ewe. Forty ewes were assigned to be necropsied on days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or pregnancy (D13-P and...

In Vivo and In Vitro effects of a cyclopropenoid fatty acid on progesterone synthesis by the ovine corpus luteum

Creator:: Tumbelaka, Ligaya
Abstract:: Two experiments were conducted to examine the effect of a cyclopropenoid fatty acid on luteal cell function. In Exp. 1, 12 mature ewes were mated to a fertile ram, assigned to two groups (n = 6/group) and laparotomized on day 18 of gestation. Ewes with corpora lutea (CL) in both...

Involvement of myristoylated alanine-rich c kinase substrate (MARCKS) protein in prostaglandin F2α- induced secretion of oxytocin by the bovine corpus luteum

Creator:: Salli, Ugur
Abstract:: Prostaglandin F₂α (PGF₂α), a stimulatory hormone of luteal oxytocin secretion, is known to activate protein kinase C (PKC); however, the intracellular signals that promote exocytosis of oxytocin remain to be elucidated. Myristoylated alanine-rich C kinase substrate (MARCKS), a protein specifically phosphorylated by PKC, crosslinks actin filaments associated with the inner...

Response of the bovine corpus luteum to exogenous gonadotropin-releasing hormone during the estrous cycle

Creator:: Martin, Teri L.
Abstract:: Two experiments were conducted to investigate the effects of gonadotropin-releasing hormone (GnRH), administered twice during the same estrous cycle, on bovine luteal function. Eight mature beef cows, each cow serving as her own control, were injected intravenously (i.v.) with saline on days 2 and 8 of the cycle (day of...

Bovine luteal oxytocin synthesis and secretion in vitro : effects of phorbol ester, calcium ionophore and indomethacin

Creator:: Cosola-Smith, Carrie A.
Abstract:: Experiments were conducted to examine the effects of a tumor-promoting phorbol ester, a calcium ionophore and indomethacin on bovine luteal oxytocin (OT) synthesis and secretion and progesterone secretion. Six 18-month-old crossbred beef heifers in Exp. 1 and five similar heifers in Exp. 2 were observed twice daily for estrus using...

Nongenomic action of progesterone inhibits oxytocin signaling through the ovine oxytocin receptor

Creator:: Bishop, Cecily V.
Abstract:: Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin receptor (OTR) and signal transduction. The dose-response relationship of P4 to OT binding to the OTR in endometrium was examined. Progesterone interfered with the binding of OT to the OTR...

Abstract:: Effects of progesterone (P₄) and mifepristone (RU 486) on binding of oxytocin (OT) to its ovine uterine receptor (OTR) were studied in two experiments. Two additional experiments were conducted to evaluate specific binding sites for P4 in endometrial plasma membranes. In Exp. 1, ovariectomized ewes were injected with estradiol-17β (E₂)...
