Project description:In this study, we focused on the changes of mRNA expression in bovine oviduct epithelial cells in vitro co-cultured with embryos during preimplantation development in order to identify genes, which might be involved in embryo-maternal communication. For this purpose, we used large-scale cDNA microarray hybridizations to identify the genes differentially regulated in bovine oviduct epithelial cells (Boec) during in vitro culture. The main objective was to identify genes which are differentially expressed due to the presence or absence of bovine embryos on cell monolayers. Global transcriptional profiling was performed using 13 days Bovine oviduct epithelial cells (Boec) cultured in vitro with SOF media RNA as control samples (BOEC_SOF_CTL, n=3) for comparison to the experimental samples taken at the same culture time (day 13) and stimulated by the presence of bovine embryos during the last 8 days of culture (BOEC_SOF+EMB, n=3).Gene expression analysis was carried out between Boec with or without stimulation of embryos representing a total of 6 slides (dye swap protocol).

Project description:The objective of this study was to examine the effect of the presence of a single or multiple embryo(s) on the transcriptome of the bovine oviduct. In Experiment 1, cyclic (non-bred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells from the isthmus region, in which all oocytes/embryos were located, were snap-frozen for microarray analysis. In Experiment 2, heifers were divided into cyclic (non-bred, n = 6) or pregnant (multiple embryo transfer, n = 10) groups. In vitro-produced presumptive zygotes were transferred endoscopically to the ipsilateral oviduct on Day 1.5 post estrus (n = 50 zygotes per heifer). Heifers were slaughtered on Day 3 and oviductal isthmus epithelial cells were recovered for RNA sequencing. Microarray analysis in Experiment 1 failed to detect any difference in the transcriptome of the oviductal isthmus induced by the presence of a single embryo. In Experiment 2, following multiple embryo transfer, RNA sequencing revealed 278 differentially expressed genes of which 123 were up- and 155 were down-regulated in pregnant heifers. Most of the down-regulated genes were related to immune function. Five samples from pregnant heifers and five control, cyclic heifers were analysed

Project description:Neonatal genistein treatment causes complete infertility in adult mice. Part of their infertility can be attributed to a loss of 50% of the preimplantation embryos during transit through the oviduct between days 2 and 3 of pregnancy. Comparison of the gene expression signatures of oviducts collected on pregnancy day 2 revealed significant alterations in gene expression, particularly in genes involved in development and the inflammatory response. These findings were verified by real time PCR and in some cases at the protein level by immunoblotting or immunohistochemistry.

Project description:Ciliary action performs a critical role in the oviduct (Fallopian tube), during pregnancy establishment through sperm and egg transport. The disruption of normal ciliary function in the oviduct affects oocyte pick-up and is a contributing factor to female infertility. Estrogen is an important regulator of ciliary action in the oviduct and promotes ciliogenesis in several species. Global loss of estrogen receptor 1 alpha (encoded by Esr1 gene) leads to infertility. Our laboratory has previously shown that ESR1 in the oviductal epithelial cell layer is required for female fertility. Here, we assessed the role of estrogen on transcriptional regulation of ciliated epithelial cells of the oviduct using single-cell RNA-sequencing analysis. We observed minor variations in ciliated cell genes in the proximal region (isthmus and uterotubal junction) of the oviduct. However, E2 treatment had little impact on the gene expression profile of ciliated epithelial cells. To assess the requirement of ESR1 specifically in ciliated cells for female fertility, we conditionally ablated Esr1 from ciliated epithelial cells of the oviduct (called ciliated Esr1d/d mice). Our studies showed that ciliated Esr1d/d females had fertility rates comparable to control females, did not display any disruptions in preimplantation embryo development or embryo transport to the uterus, and had comparable cilia formation to control females. However, we observed some incomplete deletion of Esr1 in the ciliated epithelial cells, especially in the ampulla region. Therefore, more studies are required to definitively determine ESR1 function in ciliated cells of the oviduct. Nevertheless, our data suggest that ESR1 expression in ciliated cells of the oviduct is dispensable for ciliogenesis, but nonessential for female fertility in mice.

Project description:While the equine oviduct clearly affects early embryo development and while the selective transport of equine embryos through the oviduct indicates a reciprocal interaction, the influence of the embryo on gene expression in the oviduct remains to be determined in the horse. The aim of this study was to examine this by means of RNA sequencing. Four days after ovulation, the oviduct epithelial cells ipsilateral and contralateral to the ovulation side from five cyclic and five pregnant mares were collected. mRNA was extracted and samples were sequenced using the Illumina Hiseq-2000 sequencer. Data analysis was performed with the CLC Genomics software and differentially expressed genes (DEGs) were determined (p-value ≤ 0.05 and absolute fold change ≥ 2). ClueGO was used for functional interpretation. A total of 26,991 genes was identified and 253 genes were found to be upregulated and 108 to be downregulated in the pregnant ipsilateral oviduct, when compared to the cyclic ipsilateral oviduct. Comparison of the ipsilateral and the contralateral oviduct indicated 164 DEGs in pregnant mares and 77 DEGs in cyclic mares. Functional enrichment analysis only detected differences in the comparison of pregnant and cyclic ipsilateral oviducts and showed that the equine embryo affects the expression of immune response related genes in the oviduct, with marked upregulation of interferon associated genes. This research represents the foundation for further assessment of the role of specific genes in the early embryo-maternal dialogue of the horse.

Project description:Our results indicated that conditional knockout of Cdc42 in the epithelial cells of the oviduct isthmus led to defective embryo transport, resulting in blastocytes retention in oviduct, and contributing to the pregnancy failure in PgrCreCdc42f/f mice. To further determine the role of CDC42 in oviduct, RNA-seq analysis was applied in the Cdc42f/f and PgrCreCdc42f/f mice oviduct on day 2 of pregnancy.

Project description:We aimed to verify whether and to which extent a perturbed nutrient environment during embryo development impact on the capacity of the resultant blastocyst to participate in initial embryo-maternal interactions. For this, in vitro-derived bovine zygotes were exposed to perturbed nutritional environments during the first days of their development. On Day 4 (post fertilization), groups of 5 morulas were transfered to sub-confluent Bovine Endometrial Epithelial Cell (BEEC) monolayers. Embryos were cocultured with BEEC until Day 8, when endometrial cells were recovered for transcriptome analysis.
