Prostaglandin F α-induced signal transduction mechanism regulating the secretion of oxytocin from the bovine corpus lutem

Creator:: Orwig, Kyle Edwin
Resource Type:: Dissertation
Full Text:: C (PKC) present in the bovine corpus luteum (CL) and their subcellular distribution. In addition

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...

Embryonic mortality in pubertal gilts

Creator:: Archibong, Anthony Effanga
Abstract:: An experiment was conducted to compare the reproductive performance and serum concentrations of progesterone and estrogen of mated first (n=18) and third (n=18) estrous gilts slaughtered in equal numbers on days 3, 15 and 30 postmating. Fertilization rate did not differ between mated first and third estrous gilts. Embryonic survival...

Gonadotropin releasing hormone-induced secretion of luteinizing hormone during the milk ejection reflex in the postpartum beef cow

Creator:: Jaeger, John Ralph
Abstract:: A study was conducted to determine the effect of the milk ejection reflex on exogenous gonadotropin releasing hormone (GnRH)- induced release of luteinizing hormone (LH) after short term calf removal. Twenty-four postpartum multiparous beef cows were assigned 3 randomly to groups arranged in a 2[superscript 3] factorial design to be...

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...

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...

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...

Some effects of estradiol on ovine luteal function

Creator:: Akbar, Abulfatah Maqsood, 1938-
Abstract:: Some effects of 171β-estradiol on ovine luteal function were studied in five experiments. Estradiol injected into ewes on days 11 and 12 of the estrous cycle caused luteal regression in both intact and unilaterally hysterectomized ewes indicating that the presence of one uterine horn permits estradiol to cause luteolysis comparable...

Physiological factors affecting ovine uterine estrogen and progesterone receptor concentrations

Creator:: Prater, Patrice L.
Abstract:: Two experiments were conducted to determine whether in ewes uterine concentrations of estrogen and progesterone receptors are affected by the presence of a conceptus or by the hormonal milieu associated with extremes in photoperiod to which ewes are exposed. In Exp.1, nine mature ewes were unilaterally ovariectomized by removing an...
