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...

Factors affecting luteal oxytocin synthesis and/or secretion by the ovine and bovine corpus luteum

Creator:: Paslay, Elizabeth M.
Abstract:: Experiments were conducted to determine whether endogenous progesterone regulates synthesis and/or secretion of luteal oxytocin (OT). In experiment 1, mature ewes (n=5 per group) were assigned randomly to control or mifepristone (RU 486) treatment groups. Ewes were injected twice daily s.c. with vehicle or 10 mg RU 486 from days...

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...

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...

Cellular mechanisms of altered bovine luteal function in response to exogenous gonadotropin-releasing hormone

Creator:: Bertrand, Jennifer Elaine
Abstract:: To determine whether membrane-related events may be involved in attenuated luteal function after gonadotropin-releasing hormone (GnRH) administration, corpora lutea (CL) were removed from 10 beef heifers on day 7 of the estrous cycle after i.v. injection of GnRH or saline on day 2 of the cycle. Luteal slices were incubated...
