Abstract
During early embryonic development, late fetal growth, puberty, adult reproductive years, and advanced aging, bovine and human ovaries closely share molecular pathways and hormonal signaling mechanisms. Other similarities between these species include the size of ovaries, length of gestation, ovarian follicular and luteal dynamics, and pathophysiology of ovarian diseases. As an economically important agriculture species, cattle are a foundational species in fertility research with decades of groundwork using physiologic, genetic, and therapeutic experimental techniques. Many technologies used in modern reproductive medicine, such as ovulation induction using hormonal therapy, were first used in cows before human trials. Human ovarian diseases with naturally occurring bovine correlates include premature ovary insufficiency (POI), polycystic ovarian syndrome (PCOS), and sex-cord stromal tumors (SCSTs). This article presents an overview of bovine ovary research related to causes of infertility, ovarian diseases, diagnostics, and therapeutics, emphasizing where the bovine model can offer advantages over other lab animals for translational applications.

Abstract
Oviductal glycoprotein 1 (OVGP1), an oviductin, is involved in the maintenance of sperm viability and motility and contributes to sperm capacitation in the oviduct. In this study, the regulatory effects exerted by
prostaglandin E2 (PGE2) and F2α (PGF2α) on OVGP1 expression via their corresponding receptors in bovine oviductal epithelial cells (BOECs) were investigated. BOECs were
cultured in vitro, and their expression of receptors of PGE2 (PTGER1, PTGER2, PTGER3, and PTGER4) and PGF2α (PTGFR) was measured using RT-qPCR. Ca2+ concentration was
determined with a fluorescence-based method and cAMP was quantified by enzyme-linked immunosorbent assays to verify activation of PTGER2 and PTGFR by their corresponding agonists in these cells. OVGP1 mRNA and protein
expression was measured using RT-qPCR and western blotting, respectively, following PTGER2 and PTGFR agonist-induced activation. PTGER1, PTGER2, PTGER4, and PTGFR were found to be present in BOECs; however, PTGER3
expression was not detected. OVGP1 expression was significantly promoted by 10–6 M butaprost (a PTGER2 agonist) and decreased by 10–6 M fluprostenol (a PTGFR agonist). In addition, 3 μM H-89 (a PKA
inhibitor) and 3 μM U0126 (an ERK inhibitor) effectively inhibited PGE2-induced upregulation of OVGP1, and 5 μM chelerythrine chloride (a PKC inhibitor) and 3 μM U0126 negated OVGP1 downregulation by
PGF2α. In conclusion, this study demonstrates that OVGP1 expression in BOECs is enhanced by PGE2 via PTGER2-cAMP-PKA signaling, and reduced by PGF2α through the
PTGFR-Ca2+-PKC pathway.

Abstract
Successful establishment of pregnancy is required for fetal-maternal interactions regulating implantation, embryonic development and placentation. A uterine environment with insufficient growth factors and nutrients increases the incidence of intrauterine growth restriction (IUGR) leading to an impaired uterine environment. In the present study, we demonstrated the effects of the phytoestrogen coumestrol on conceptus development in the pig that is regarded as an excellent biomedical animal model for research on IUGR. Results of this study indicated that coumestrol induced migration of porcine trophectoderm (pTr) cells in a concentration-dependent manner. In response to coumestrol, the phosphorylation of AKT, P70S6K, S6, ERK1/2 MAPK, and P90RSK proteins were activated in pTr cells and ERK1/2 MAPK and P90RSK phosphorylation was prolonged for a longer period than for the other proteins. To identify the signal transduction pathway induced by coumestrol, pharmacological inhibitors U0126 (an ERK1/2 inhibitor) and LY294002 (a PI3K inhibitor) were used to pretreat pTr cells. The results showed that coumestrol-induced phosphorylation of ERK1/2 MAPK and P90RSK was blocked by U0126. In addition, the increased phosphorylation in response to coumestrol was completely inhibited following pre-treatment incubation of pTr cells in the presence of LY294002 and U0126. Furthermore, these two inhibitors suppressed the ability of coumestrol to induce migration of pTr cells. Collectively, these findings suggest that coumestrol affects embryonic development through activation of the PI3K/AKT and ERK1/2 MAPK cell signal transduction pathways and improvement in the uterine environment through coumestrol supplementation may provide beneficial effects of enhancing embryonic and fetal survival and development.
