Abstract
The oviduct is a dynamic organ that suffers changes during the oestrous cycle and modulates gamete and embryo physiology. We analyse the possible existence of Protein kinase A (PKA)-dependent hormone-regulated pathways in porcine ampulla and primary cell cultures by 2D-electrophoresis/Western blot using anti-phospho PKA substrate antibodies. Differential phosphorylation was observed for ten proteins that were identified by mass spectrometry. The results were validated for five of the proteins: Annexin A5, Calumenin, Glyoxalase I and II and Enolase I. Immunofluorescence analyses show that Calumenin, Glyoxalase II and Enolase I change their localisation in the oviductal epithelium through the oestrus cycle. The results demonstrate the existence of PKA hormone-regulated pathways in the ampulla epithelium during the oestrus cycle.

Abstract
Avaliaram-se o desenvolvimento e a qualidade de embriões bovinos, cocultivados com células epiteliais do oviduto bovino (CEOBs) expostas ou não ao estradiol e à progesterona. Os ovócitos foram maturados in vitro por 24h e, então, fertilizados utilizando-se sêmen congelado, em estufa de CO2 a 5% e 38,5ºC. As CEOBs foram cultivadas em TCM-199 com ou sem estradiol (E2) (24 horas), nas mesmas condições da maturação e fertilização in vitro (MIV e FIV), e, em seguida, adicionadas aos diferentes grupos em CR2 com ou sem progesterona (P4) (G1=P4+E2); (G2=E2); (G3=P4) e (G4=controle). Após 18h da FIV, as células foram cultivadas nos diferentes sistemas. Nenhuma diferença (P>0,05) foi observada nas taxas de clivagem entre G1, G2 e G4 (53,5%; 56,3%; 51,7%) e nos padrões de blastocistos (BLs) (29,3%; 31,2%, 28,7%). Índices menores (P<0,05) foram obtidos no G3 para ambas as variáveis (34,5%; 16,4%). G1 e G2 apresentaram taxas de eclosão maiores (P<0,05) que os outros grupos (23,3%; 23,2%), sendo G4 (19,3%) diferente de G3 (16,1%). Em G1, G2 e G3, o número de células nos BLs aumentou 125,9; 128,4 e 123,6, respectivamente (P<0,05), em relação ao G4 (112,5). Conclui-se que o tratamento das CEOBs com o E2, nas primeiras 24 horas de cultivo, pode ser usado isoladamente ou em combinação com a progesterona, a fim de melhorar a qualidade de embriões bovinos produzidos in vitro

Abstract
A comprehensive understanding of the complex embryo-maternal interactions during the preimplantation period requires the analysis of very early stages of pregnancy. These are difficult to assess in vivo due to the small size of the embryo exerting local paracrine effects. Specifically designed experiments and holistic transcriptome and proteome analyses to address the early embryo-maternal cross-talk in the oviduct require sufficient numbers of well-defined cells in a standardized experimental environment. The pronounced estrous cycle-dependent changes in gene expression and morphology of bovine oviduct epithelial cells (BOECs) clearly show that a precise definition of the stage of estrous cycle is essential for obtaining a well-defined homogenous population of functional cells. The number of intact cells isolated from individual ampullae by solely mechanical means was 10-fold higher than previously reported cell yields after enzymatic treatment, and the purity was comparable. Bovine oviduct epithelial cells have been cultured as monolayers or in suspension. Proliferating cells grown in monolayers dedifferentiated, with a concomitant loss of important morphologic characteristics. After several days in culture, BOECs in monolayers are less likely to mimic the oviduct environment in vivo than BOEC vesicles formed of epithelial sheets in short-term suspension culture. A 24-h culture system for BOECs isolated on Day 3.5 of the estrous cycle showed excellent preservation of morphologic criteria, marker gene expression, and hormone responsiveness. The short-term BOEC culture system provides well-defined and functional BOECs in sufficient quantities for studies of early embryo-maternal interactions in experiments that mimic the environment in the oviduct in vivo.

The secretions of oviduct epithelial cells increase the equine in vitro fertilization rate: are osteopontin, atrial natriuretic peptide A and oviductin involved? Reprod Biol Endocrinol 2009; 7:129. [PMID: 19925651 PMCID: PMC2785818 DOI: 10.1186/1477-7827-7-129] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2009] [Accepted: 11/19/2009] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Oviduct epithelial cells (OEC) co-culture promotes in vitro fertilization (IVF) in human, bovine and porcine species, but no data are available from equine species. Yet, despite numerous attempts, equine IVF rates remain low. Our first aim was to verify a beneficial effect of the OEC on equine IVF. In mammals, oviductal proteins have been shown to interact with gametes and play a role in fertilization. Thus, our second aim was to identify the proteins involved in fertilization in the horse. METHODS & RESULTS In the first experiment, we co-incubated fresh equine spermatozoa treated with calcium ionophore and in vitro matured equine oocytes with or without porcine OEC. We showed that the presence of OEC increases the IVF rates. In the subsequent experiments, we co-incubated equine gametes with OEC and we showed that the IVF rates were not significantly different between 1) gametes co-incubated with equine vs porcine OEC, 2) intact cumulus-oocyte complexes vs denuded oocytes, 3) OEC previously stimulated with human Chorionic Gonadotropin, Luteinizing Hormone and/or oestradiol vs non stimulated OEC, 4) in vivo vs in vitro matured oocytes. In order to identify the proteins responsible for the positive effect of OEC, we first searched for the presence of the genes encoding oviductin, osteopontin and atrial natriuretic peptide A (ANP A) in the equine genome. We showed that the genes coding for osteopontin and ANP A are present. But the one for oviductin either has become a pseudogene during evolution of horse genome or has been not well annotated in horse genome sequence. We then showed that osteopontin and ANP A proteins are present in the equine oviduct using a surface plasmon resonance biosensor, and we analyzed their expression during oestrus cycle by Western blot. Finally, we co-incubated equine gametes with or without purified osteopontin or synthesized ANP A. No significant effect of osteopontin or ANP A was observed, though osteopontin slightly increased the IVF rates. CONCLUSION Our study shows a beneficial effect of homologous and heterologous oviduct cells on equine IVF rates, though the rates remain low. Furthers studies are necessary to identify the proteins involved. We showed that the surface plasmon resonance technique is efficient and powerful to analyze molecular interactions during fertilization.

Abstract
Our objectives were to compare proteins secreted by caprine oviductal explants and oviductal epithelial (OE) cells in vitro. Oviducts were collected from goats on Days 1 (n=5) and 5 (n=5) of the estrous cycle. Radiolabeled secretory proteins from tissue segments and cell cultures were visualized using SDS-PAGE and fluorography. After culture, media from ampulla oviduct segments collected on Days 1 and 5 of the estrous cycle contained an acidic 97 kDa protein, which was greatly reduced in culture medium obtained from infundibulum and isthmus oviduct segments. A complex of low molecular weight proteins (14-26 kDa) could be modulated by estradiol when OE cells were cultured on plastic. This complex was constitutively expressed when OE cells were cultured on Matrigel-coated filters. Polarized OE cells were also capable of compartment-specific secretion of [L-(35)S]-methionine-labeled proteins. A 45 kDa acidic protein was predominantly secreted into the apical compartment while a 66 kDa acidic protein was preferentially localized in the basal compartment. Proteins secreted by OE cells were similar to proteins secreted by tissue segments in vitro. Therefore, under well-defined culture conditions OE cells may be useful in enhancing in vitro fertilization or early embryonic development.

Abstract
This study was conducted to evaluate the effect of adrenal stimulation by synthetic adrenocorticotrophic hormone (ACTH) on the first 2 days of pregnancy in 22 multiparous sows. The experiment was performed during the second oestrus after weaning and the sows were divided into one control (C-group) and one experiment group (E-group). To determine the time of ovulation, transrectal ultrasonographic examination was performed. E-group sows were treated repeatedly with 0.1 mg/kg bodyweight of synthetic ACTH (tetracosactide) i.v. 4-8h after ovulation and continuing every 6h, until slaughter. Blood samples were collected every second hour from about 12h before expected ovulation until slaughter and were analyzed for cortisol, prostaglandin F(2 alpha) -metabolite, and progesterone (P(4)). All sows were slaughtered approximately 48 h after ovulation and the isthmic part of the oviduct was divided into three equally long segments and flushed separately with phosphate buffered saline (PBS). The uterine horns were also flushed with PBS. The embryos of the E-group sows tended (P=0.056) to have a lower cleavage rate than the embryos of the C-group sows but there was no difference between groups in oviductal transport rate of the embryos. In the E-group, significantly (P<0.05) more sows had only embryos with <20 spermatozoa attached to the ZP compared with the C-group. The plasma concentration of cortisol was significantly higher (P<0.0001) in the E-group sows during the time of treatment while the baseline level of prostaglandin F(2 alpha) -metabolite was significantly lower. The baseline level of progesterone increased in both groups after ovulation but there was no significant difference between the groups. Repeated ACTH-stimulation (1) had no effect on the oviductal transport rate of the embryos, (2) had a negative effect on the embryo development, (3) and caused a changed endocrine profile that might have changed oviductal milieu affecting embryo development.

Abstract
Although estrogen is recognized as essential for embryonic development and maintenance of pregnancy, it remains unclear whether it has a direct role in the embryos themselves. The aim of this study was to investigate whether estrogen can have any effect in pig embryos during preimplantation development. Since the function of estrogen is mediated through its specific receptor, estrogen receptor (ER), the presence of ER mRNA and protein in pig embryos collected in vivo at different stages of preimplantation development was determined and compared. Using reverse transcription polymerase chain reaction, ER RNA was detected at the one-cell, two-cell, and four-cell stages. The level became undetectable at the five- to eight-cell stages and the morula stages and then reappeared again at the blastocyst stage. To determine whether the ER message observed in the embryos was translated into ER protein, immunocytochemical analysis was performed and the presence of ER protein was detected in oocytes at one-cell and four-cell stages. However, the amount of ER protein in porcine embryos at the blastocyst stage was still below the detection limit. The presence of ER mRNA at the blastocyst stages suggests that estrogen may start to act directly on pig embryos afterwards, and our results provide a basis for determining the direct role of estrogen in preimplantation pig embryos.
