Previously, it was reported that chronic intra-uterine infusion of PGE(1) or PGE(2) every four hours inhibited luteolysis in ewes. However, estradiol-17β or PGE(2) given intra-uterine every 8h did not inhibit luteolysis in heifers, but infusion of e

Recombinant equine luteinizing hormone (reLH) was evaluated for its ability to stimulate production of progesterone in cell lines from three species including murine Leydig tumor (MA-10), equine granulosal, and ovine small luteal cells (SLC). The res

The objectives of this study were to determine whether activation of estrogen receptor 1 (ESR1; also known as ERalpha), or estrogen receptor 2 (ESR2; also known as ERbeta), or both are required to: 1) acutely inhibit secretion of LH, 2) induce the pr

The objective of the present study was to determine how rapidly estradiol (E2) was able to suppress the secretion of LH in ovariectomized (OVX) ewes and to evaluate the ability of conjugated forms of E2 (E2 conjugated to BSA [1,3,5(10)-estratrien-3,1

The objective of the present study was to determine the ability of 17β-estradiol (E2) and conjugated forms of E2 (E2 conjugated to BSA [E2-BSA] and a novel conjugate, E2 conjugated to a small peptide [E2-PEP]) to prevent the GnRH-induced secretion o

Previously, it was reported that chronic intra-uterine infusion of PGE(1) or PGE(2) every 4h inhibited luteolysis in ewes by altering luteal mRNA for luteinizing hormone (LH) receptors and unoccupied and occupied luteal LH receptors. However, estradi

Thirty to forty percent of ruminant pregnancies are lost during the first third of gestation due to inadequate progesterone secretion. During the estrous cycle, luteinizing hormone (LH) regulates progesterone secretion by small luteal cells (SLC). Lo

Background We demonstrated that E2 conjugated to BSA (E2BSA) induces a rapid membrane-initiated inhibition of LH secretion followed hours later by a slight increase in LH secretion. Whether these actions of E2BSA are restricted to the pituitary gland

The objectives of this study were: to determine if peripheral administration of the ovine C-terminal decapeptide (oKiSS-1) increases secretion of LH and FSH in ovariectomized (OVX) ewes; to evaluate the effect of ovarian steroid hormones on the predi
