Project description:The success of the early reproductive events depends on an appropriate communication between gametes/embryos and the oviduct. Extracellular vesicles (EVs) contained in oviductal secretions have been suggested as new players in mediating this crucial cross-talk by transferring their cargo (e.g. proteins, mRNA and small ncRNA) from cell to cell. However, little is known about the oviduct EVs composition and their implications in reproductive success. The objective of our study was to determine the changes of oviductal EVs mRNA content under the hormonal influence during the estrous cycle. Methods: EVs, exosomes and microvesicles, were isolated from bovine oviductal fluid at different stages of the estrous cycle (postovulatory-stage, early luteal phase, late luteal phase and pre-ovulatory stage). Total RNA was isolated and used for the preparation of RNA-seq libraries. RNA-sequencing was performed on an Illumina HiSeq 2500. The obtained sequence reads that passed quality filters were mapped to the bovine genome sequence using Hisat 2. Read counts were calculated with QuasR Qcount and statistical analysis with EdgeR to identify differential mRNA abundance across the different stages of the estrous cycle. Results: RNA-sequencing identified 903 differentially expressed transcripts (FDR<0.001) in bovine oviductal EVs across the estrous cycle. Major differences were found between post-ovulatory and the rest of the stages analyzed.Functional annotation of the differentially abundant mRNAs identified functions related to cilia expression, exosome/vesicles, and many transcripts encoding ribosomal proteins. Conclusions: Our findings represent the first extensive oviductal signature of bovine oviductal EVs mRNA content and contribute to a better understanding of the role of EVs as modulators of gamete/embryo-maternal interactions.

Project description:The success of the early reproductive events depends on an appropriate communication between gametes/embryos and the oviduct. Extracellular vesicles (EVs) contained in oviductal secretions have been suggested as new players in mediating this crucial cross-talk by transferring their cargo (e.g. proteins, mRNA and small ncRNA) from cell to cell. Therefore, the objective of the project was to analyze the protein content of EVs (exosomes and microvesicles) contained in the bovine oviductal fluid at different stages of the estrus cycle. For this purpose, pairs of oviducts with their attached ovaries were collected from cyclic cows at a local abattoir under different hormonal regulation along the estrous cycle. Oviducts were classified into one of the 4 stages of the estrous cycle according to the morphology of the corpus lutea(CL) and follicle populations: Stage 1 (S1): showed recently ovulated follicle (d 1 to 4 of estrous cycle); Stage 2 (S2): early luteal development with medium or large or both present (d 5 to 11); Stage 3 (S3): fully functional CL yellow or orange in color (d 11 to 17); or Stage 4 (S4): regressing CL with little vasculature and a large preovulatory follicle present (d 18 to 20). EVs were collected by ultracentrifugation and prepared for mass spectrometry analysis.

Methods: EVs, exosomes and microvesicles, were isolated from bovine oviductal fluid at different stages of the estrous cycle (postovulatory-stage, early luteal phase, late luteal phase and pre-ovulatory stage). RNA enriched for short molecules was isolated and used for the preparation of small RNA-seq libraries. RNA-sequencing was performed on an Illumina HiSeq 2500. The obtained sequence reads that passed quality filters were annotated by BLAST alignment to various sets of non-coding and coding RNAs. Read counts were calculated based on the frequency of unique sequences after removal of PCR duplicates. Statistical analysis was done with EdgeR to identify differential small ncRNA abundance across the different stages of the estrous cycle. Results: Small RNA-Seq identified the presence of different types of ncRNAs (miRNAs, rRNA fragments, tRNA fragments, snRNA, snoRNA, and other ncRNAs), which were partially also under hormonal influence. Major differences were found between post-ovulatory and early luteal and the rest of the stages for small ncRNAs. Interesting miRNAs identified in oviductal EVs, miR-34b and miR-449a, showed differential abundance among stages. Dysregulation of these miRNAs has been associated with defective cilia in the oviduct and infertility. Conclusions: Our findings represent the first extensive oviductal signature of bovine oviductal EVs miRNA content and contribute to a better understanding of the role of EVs as modulators of gamete/embryo-maternal interactions.

Project description:To determine functional differences between the corpus luteum (CL) of the estrous cycle and pregnancy in cows, gene expression profiles between the CL of the estrous cycle and pregnancy were investigated. A 15 K bovine oligo DNA microarray detected 138, 265 and 455 differentially expressed genes (>2-fold; P<0.05) in the bovine CL of 20-25, 40-45, and 150-160 days of pregnancy compared with 10-12 days of the estrous cycle. The different gene expression profiles may contribute to functional differences between the CL of pregnancy and the CL of the estrous cycle in cows. Chemokines including eotaxin and lymphotactin may regulate CL function during pregnancy. Bovine ovaries containing corpora lutea (CLs) were obtained from Japanese-Black cows in the institute ranch within 10-30 min of exsanguination. Tissue samples were collected from cows on 10-12 days of the estrous cycle (cyclic), 20-25, 40-45, and 150-160 days of the gestation (n=4 animals/stage). The day of artificial insemination was designated as day 1.

Project description:The endometrium provides optimal conditions for the transport of sperm to the oviduct, to the site of fertilization, and later on for the reception of the embryo. To study these changes on the level of gene expression, a messenger RNA expression profiling of endometrium tissue samples collected from 19 cyclic heifers at five stages of the estrous cycle (days 0, 3.5, 12, 18, 20) was performed. RNA was extracted from these tissue samples and analyzed with a custom-made bovine oviduct and endometrium (BOE) cDNA array. The cDNAs present on the array were derived from several previously conducted differential gene expression studies of bovine endometrium between different stages of the estrous cycle, during early pregnancy, and from studies of bovine oviduct epithelial cells. In all of these studies cDNAs of differentially expressed genes were identified using a combination of subtracted cDNA libraries and cDNA array hybridization. 1,440 cDNA fragments are located on the array. Twenty radioactively labeled cDNA samples (n=4 for each cycle stage) were hybridized with BOE arrays. Raw data were normalized using the BioConductor package vsn. Keywords: time course of gene expression in bovine endometrium during estrous cycle Nineteen German Fleckvieh (Simmental) heifers were slaughtered at four different days of the estrous cycle, four animals at day 0, four at day 3.5, three at day 12 and eight animals at day 18. Four of the day 18 animals showed high and the other four low serum progesterone (P4) levels, respectively. This resulted in five groups of endometrial tissue samples corresponding to five stages of the estrous cycle.

Project description:We analyzed the transcriptome of the C57BL/6J mouse hypothalamus, hippocampus, neocortex, and cerebellum to determine estrous cycle-specific changes in these four brain regions. We found almost 16,000 genes are present in one or more of the brain areas but only 210 genes, ~1.3%, are significantly changed as a result of the estrous cycle. The hippocampus has the largest number of differentially expressed genes (DEGs) (82), followed by the neocortex (76), hypothalamus (63), and cerebellum (26). Most of these DEGs (186/210) are differentially expressed in only one of the four brain regions. A key finding is the unique expression pattern of growth hormone (Gh) and prolactin (Prl). Gh and Prl are the only DEGs to be expressed during only one stage of the estrous cycle (metestrus). To gain insight into the function of the DEGs, we examined gene ontology and phenotype enrichment and found significant enrichment for genes associated with myelination, hormone stimulus, and abnormal hormone levels. Additionally, 61 of the 210 DEGs are known to change in response to estrogen in the brain. 50 genes differentially expressed as a result of the estrous cycle are related to myelin and oligodendrocytes and 12 of the 63 DEGs in the hypothalamus are oligodendrocyte- and myelin-specific genes. This transcriptomic analysis reveals that gene expression in the female mouse brain is remarkably stable during the estrous cycle and demonstrates that the genes that do fluctuate are functionally related.

Project description:The equine endometrium exhibits characteristic morphological and functional changes during the estrous cycle controlled by the interplay of progesterone and estradiol. A microarray analysis of endometrial tissue samples derived from 5 time points of the estrous cycle (D0, D3, D8, D12, and D16) was performed to study the dynamics of endometrial gene expression. Endometrial biopsies were collected from five mares (Bavarian Warmblood) at the respective time points. Samples were divided and subjected to isolation of RNA for microarray analysis and analysis of tissue composition. Blood samples were collected to determine serum progesterone levels for every sample. Statistical analysis of microarray data revealed almost 10,000 differential probes corresponding to 4,996 differentially expressed genes. A cluster analysis based on gene expression profiles during the estrous cycle revealed 8 major gene expression profiles: mRNAs with highest levels 1) at D0, 2) from D0 to D3, 3) at D3, 4) from D3 to D8, 5) at D8, 6) from D8 to D12, 7) from D12 to D16, and 8) at D16. DAVID Functional Annotation Clustering revealed overrepresentation of distinct functional terms in different phases of the cycle, e.g. M-bM-^@M-^Xextracellular matrixM-bM-^@M-^Y and M-bM-^@M-^Xprotein transportM-bM-^@M-^Y during estrus, M-bM-^@M-^XDNA replication and M-bM-^@M-^Xcell cycleM-bM-^@M-^Y during early luteal phase, M-bM-^@M-^Xendoplasmic reticulumM-bM-^@M-^Y and M-bM-^@M-^Xprotein transportM-bM-^@M-^Y in the luteal phase, and M-bM-^@M-^Xinflammatory responseM-bM-^@M-^Y in the late luteal and follicular phase. Expression of selected genes of the expression clusters was validated by quantitative Real-time PCR (qPCR). This study provides new insights into global changes of equine endometrial gene expression during the estrous cycle. Equine endometrial tissue samples were collected at 5 time points during the sexual (estrous) cycle from 5 mares (5 biological replicates per time point) and analyzed with Agilent microarrays.

Project description:Purpose: Extracellular vesicles (EVs) are nanoparticles that can be secreted by different cells, including cells found within the ovarian follicle. Currently, EVs are considered an important form of intercellular communication, since they carry biological contents. The goal of this study was to survey the effects of small EVs from follicles at different estrous cycle stage in bovine cumulus cells. Methods: We used an established model to obtain follicular fluid (FF) at early and late estrous cycle stage according to corpus luteum appearance, corresponding to low and high progesterone (P4) levels, respectively. We collected FF from 3-6 mm follicles and isolated small EVs, which were used as a supplement during in vitro maturation (IVM). Cumulus cells were collected from cumulus-oocyte complexes (COCs) pools and the RNAs were obtained and subjected to RNA sequencing. Results: The results showed that small EVs from different estrous cycle stage are capable to affect transcripts in cumulus cells and modulate different pathways and biological processes related to oocyte maturation, ovulation and immune response. Conclusion: This study demonstrated that small EVs from low and high P4 group impact the RNA profile in cumulus cells after 9 hours of in vitro maturation.
