Abstract
Gamete and embryo transport is an important function of the oviduct. This type of transport involves both smooth muscle contraction and epithelial cell secretions, and the former is mediated by prostaglandins (PGs) and their receptors. Our objective was to study the regulation of prostaglandin synthetase (prostaglandin-endoperoxide synthase-1 (PTGS1), prostaglandin-endoperoxide synthase-2 (PTGS2), mPGES-1, mPGES-2, cPGES, and PGFS) by estradiol (E2) in bovine oviduct smooth muscle. Prostaglandin synthetase mRNA and protein expression were investigated using real-time RT-PCR and Western blot analyses, respectively. Prostaglandin synthetase mRNA and protein expression were increased in oviductal smooth muscle tissue after treatment with different concentrations of estradiol for various time periods. The results indicated that there was no increase in expression observed after treatment with fulvestrant, a selective antagonist of the E2 receptor, indicating that E2 interacts with specific E2 nuclear receptors to upregulate PTGS1, PTGS2, mPGES-1, and PGFS expression. In conclusion, E2 increases PTGS1, mPGES-1, and PGFS mRNA and protein expression in bovine oviductal smooth muscle when added for different periods of time and at different concentrations. Additionally, E2 is transported intracellularly and interacts with specific E2 nuclear receptors to increase PTGS1, PTGS2, mPGES-1 and PGFS expression.

Abstract
BACKGROUND Reproductive success depends on a functional oviduct for gamete storage, maturation, fertilization, and early embryonic development. The ovarian-derived steroids estrogen and progesterone are key regulators of oviductal function. The objective of this study was to investigate luteal and follicular phase-specific oviductal epithelial cell function by using microarray-based transcriptional profiling, to increase our understanding of mRNAs regulating epithelial cell processes, and to identify novel genes and biochemical pathways that may be found to affect fertility in the future. METHODS Six normally cycling Angus heifers were assigned to either luteal phase (LP, n = 3) or follicular phase (FP, n = 3) treatment groups. Heifers in the LP group were killed between day 11 and 12 after estrus. Heifers in the FP group were treated with 25 mg PGF2α (Lutalyse, Pfizer, NY) at 8 pm on day 6 after estrus and killed 36 h later. Transcriptional profiling by microarray and confirmation of selected mRNAs by real-time RT-PCR analyses was performed using total RNA from epithelial cells isolated from sections of the ampulla and isthmus collected from LP and FP treatment groups. Differentially expressed genes were subjected to gene ontology classification and bioinformatic pathway analyses. RESULTS Statistical one-way ANOVA using Benjamini-hochberg multiple testing correction for false discovery rate (FDR) and pairwise comparison of epithelial cells in the ampulla of FP versus LP groups revealed 972 and 597 transcripts up- and down-regulated, respectively (P < 0.05). Within epithelial cells of the isthmus in FP versus LP groups, 946 and 817 transcripts were up- and down-regulated, respectively (P < 0.05). Up-regulated genes from both ampulla and isthmus were found to be largely involved in cholesterol biosynthesis and cell cycle pathways, while down-regulated genes were found in numerous inflammatory response pathways. CONCLUSIONS Microarray-based transcriptional profiling revealed phase of the cycle-dependent changes in the expression of mRNA within the epithelium of the oviducts' ampulla and isthmus.

Abstract
Angiotensin II (Ang II) and atrial natriuretic peptide (ANP) may be involved in local regulation of the oviductal contraction during the estrous cycle. Thus, the in vitro effects of Ang II and ANP on the secretion and contraction of bovine oviduct during the follicular, postovulatory, and luteal phases were investigated. An in vitro microdialysis system (MDS) was utilized to determine the intraluminal release of prostaglandins (PGs), Ang II, and endothelin-1 (ET-1) from the bovine oviducts as well as to observe the effect of Ang II and ANP on the local secretion of these substances. The basal release of PGs, ET-1, and Ang II was higher (P < 0.05) during the follicular and postovulatory phases than during the luteal phase. Stimulation by infusion of Ang II (10(-6) M) or ANP (10(-7) M) into the MDS was carried out for 4 h between 4 and 8 h of incubation. In the oviducts from the follicular and postovulatory phases, the infusion of ANP increased the release of Ang II, but not of ET-1. Infusion of Ang II stimulated the release of ET-1. Both Ang II and ANP increased PGE(2) and PGF(2alpha) release. In the contraction study, direct administration of Ang II (10(-7) M) or ANP (10(-8) M) into the medium during the follicular and postovulatory phases increased the amplitude of oviductal contraction. In contrast, these substances did not show any effect in the contraction and secretion of oviducts from cows during the midluteal phase. These results indicate that during the periovulatory period, Ang II and ANP stimulate the contractile amplitude of the oviduct in vitro. In addition to their direct action on oviductal contraction, Ang II may activate oviductal secretion of ET-1 and PGs. Likewise, ANP stimulates oviductal secretion of PGs and Ang II. Hence, the overall results suggest the existence of a functional endothelin-angiotensin-ANP system in the bovine oviduct during the periovulatory period, which may regulate the oviductal contraction to ensure maximum efficiency of gamete/embryo transport through the oviduct.

Abstract
The optimal oviductal environment, including contractile activity for gamete transport, fertilization and early embryonic development, is mediated by physiological and anatomical changes in the oviduct during the estrous cycle. Oviductal epithelial cell culture was utilized to investigate the effect of ovarian steroids (progesterone [P4] and estradiol 17 beta [E2]), oxytocin (OT) and luteinizing hormone (LH) on the local production of prostaglandin E2 (PGE2), prostaglandin F2 alpha (PGF2 alpha) and endothelin-1 (ET-1) in the cow oviduct. Epithelial cells isolated from oviducts collected during the follicular phase were cultured in M199 under standard culture conditions until monolayer formation. Then the cells were trypsinized and plated at a density of 3 x 10(4)/mL/well and cultured again until subconfluency, at which time the cells were incubated for 4 or 24 h with M199 only (control), high P4 (H-P4; 1 microgram/mL), low P4 (L-P4; 10 ng/mL), E2 (1 ng/mL), LH (10 ng/mL), OT (10(-9) M) ET-1 (10(-9) M), PGE2 (10(-8) M) PGF2 alpha (10(-9) M) or their combination (H-P4 + E2, L-P4 + E2, LH + E2, ET-1 + E2, L-P4 + E2 + LH and H-P4 + E2 + LH). The production of both PG and ET-1 was increased by E2 + low P4 and LH + E2 + low P4 (P < 0.05), while LH + E2 enhanced the production of PGF2 alpha and ET-1 (P < 0.05). Moreover, E2 + ET-1 stimulated PG production (P < 0.05). However, OT had no effect on the production of any of these substances. These results suggest that the preovulatory LH surge, together with locally re-circulated high levels of E2 from the Graafian follicle and basal P4 from regressing corpus luteum (CL), induces the maximum stimulatory effect on oviductal PGE2, PGF2 alpha and ET-1 production during the periovulatory period. Consequently, the elevated local ET-1 concentration during periovulatory period may induce the high contractile activity of the oviduct and, at the same time, the stimulation of PG production. Thus, ET-1 may act as a local amplifier for oviductal PG production stimulated by LH and ovarian steroids.

Abstract
Cyclic physio-anatomical variation in the oviducts is mediated by the local countercurrent transfer of ovarian products. Thus, in this study cow oviductal epithelial cells (COEC) culture were utilized to investigate the effects of ovarian products such as progesterone (P4), estradiol 17beta (E2) and oxytocin (OT) on local oviductal prostaglandin E2 (PGE2), F2alpha (PGF2alpha) and endothelin-1 (ET-1) production. COEC were collected from non-pregnant Holstein cows (n = 8) during the follicular phase and cultured in M199 under standard culture conditions until monolayer formation. Cells in first passage were incubated for 24 or 48 h with P4 (500 ng/ml), E2 (1 ng/ml), OT (10(-9) M) or combination of E2 + P4. Administration of E2 significantly increased the production of PGE2, PGF2alpha and ET-1. However, simultaneous administration of P4 blocked the effect of E2. OT did not show any effect on oviductal productions of either PGs or ET-1. The results of this study show that E2 stimulates PG and ET-1 production by COEC in vitro. Thus, it can be suggested that locally transferred E2 from the ovarian follicles may be important for oviductal contraction and gamete/zygote transport during the peri-ovulatory period.

Abstract
The cyclic patterns of hormones which regulate the activity of the oviduct in the cow have not been adequately reported. We studied progesterone (P4), estradiol 17 beta (E2), prostaglandin E2 (PGE2), prostaglandin F2 alpha (PGF2 alpha), oxytocin (OT) and endothelin-1 (ET-1) concentrations in the cow oviduct. Reproductive tracts from cyclic Holstein cows in the follicular phase (n = 5), post ovulation phase (n = 5) and luteal phase (n = 5) were collected at a slaughterhouse. Oviducts were separated from the uterus, the lumen vas washed with physiological saline, and the enveloping connective tissues were removed. The fimbria was then separated at first and then the rest was divided into 2 parts of equal length (proximal and distal). After extraction, levels of different hormones in the tissues were measured using double antibody enzyme immunoassays (EIAs). There were no differences in any hormone concentration between the 3 parts of the oviduct at any stage of the estrous cycle. The highest concentration of oviductal P4 was observed during the luteal phase and in the oviduct ipsilateral to the functioning CL. Oviductal OT was unchanged throughout the cycle. The highest E2 concentration was observed during the follicular phase in the oviduct ipsilateral to the dominant follicle. The oviduct ipsilateral to the dominant follicle during the follicular phase and ipsilateral to the ovulation site post ovulation showed higher levels of PGE2, PGF2 alpha and ET-1 than those on the contralateral side or during the luteal phase. The highest PGE2 was observed in the oviduct ipsilateral to the ovulation site during the post ovulation phase. The results suggest that the ovarian products (P4, OT and E2) and the local oviductal products (PGE2, PGF2 alpha, and ET-1) may synergistically control oviductal contraction for optimal embryo transport during the periovulatory period, and provide further evidence for the local delivery of ovarian steroids to the adjacent reproductive tract.

Abstract
Phospholipase A2 (EC 3.1.1.4) activity of the ampullary epithelium from rabbit oviducts was compared in the presence of various ovarian steroids to assess how they could modulate prostaglandins (PG) biosynthesis in the oviduct. The phospholipase A2 (PLA2) activity of the cells from ovariectomized rabbits (control) was 190.8 +/- 9.8 pmol/min/mg. The PLA2 activity of the cells from progesterone-treated rabbits was 156.0 +/- 41.8 pmol/min/mg and was not significantly different from the control activity. However, the PLA2 activity of the cells from the estrogen-treated rabbits was 233.5 +/- 29.0 pmol/min/mg, which was significantly higher than the control activity (p < 0.05). On the other hand, the PLA2 activity of the cells from progesterone-treated rabbits after being primed with estrogen was 116.3 +/- 25.9 pmol/min/mg, which was significantly lower than the control activity (p < 0.01). These results suggest that the effects on PLA2 activity of ovarian steroids could regulate the local production of PG which plays a role in both smooth muscle contractility and ciliary activity.
