Project description:Placentation of the conceptus to the surface epithelium is governed through a tightly regulated temporal and spatial window. Premature exogenous steriod exposure causes a shift in the maternal tissue's receptivity and prevents proper placentation. We used Affymetrix microarrays to detail the aberrant changes in uterine gene expression during this window, while removing all conceptus contribution to this dysfunction. Experiment Overall Design: Porcine endometrium was selected at chronological stages of psuedopregnancy and psuedopregnancy post endocrine disrupted early for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain homogeneous populations of normal endometrium at days 13 and 15 of the pseudo pregnant, and endometrium at days 13 and 15 of the endocrine disrupted pseudo pregnant in order to identify the temporal resolution of expression profiles. In brief, days 13 through 15 accounts for the window of attachment during pregnancy in the pig, so we created pseudo pregnant endometrium and obtained samples from days 13 (PIG13UN_TX)and 15 (PIG15UN_TX) of pseudo pregnancy. In the same, we created pseudo pregnant endometrium that was subjected to endocrine disruption of the pseudo pregnancy and collected samples on days 13 (PIG13_TX)and 15 (PIG15_TX) of pseudo pregnancy.

Project description:To compare the lncRNA expression profile of RIF (recurrent implantation failure) and normal control endometrium,endometrium samples were collected at window of implantation (LH+6~10 days) The dysregulated lncRNAs between RIF and control group were deem to be involve in the regulation of endometrium receptivity

Project description:A major unresolved issue in the cloning of mammals by somatic cell nuclear transfer (SCNT) is the mechanism by which the process fails after embryos are transferred to the uterus of recipients, prior to or during the implantation window. We investigated this problem by using RNA-seq to compare the transcriptomes in cattle conceptuses produced by SCNT and artificial insemination (AI) at d18 (pre-implantation) and d34 (post-implantation) of gestation. In addition, endometrium was profiled in order to identify the communication pathways that might be affected by the presence of a cloned conceptus, ultimately leading to mortality prior to or during the implantation window. At d18, the effects on the transcriptome associated with SCNT were massive, involving more than 5,000 differentially expressed genes (DEGs). Among them are 121 genes that have embryonic lethal phenotypes in mice, cause defects in trophoblast and placental development, and/or affect conceptus survival in mice. In endometria at d18, <0.4% of expressed genes were affected by the presence of a cloned conceptus, whereas at d34, ~36% and <0.7% of genes were differentially expressed in intercaruncular and caruncular tissues, respectively. Functional analysis of DEGs in placental and endometrial tissues suggests a major disruption of signaling between the cloned conceptus and the endometrium, particularly the intercaruncular tissue. Our results support a bottleneck model for cloned conceptus survival during the peri-implantation period determined by gene expression levels in extra-embryonic tissues and the endometrial response to altered signaling from clones.

Project description:Despite great advances in assisted reproductive technology (ART), unexplained recurrent implantation failure (RIF) due to disorder of endometrial receptivity still cannot be effectively avoided. More importantly, cell characteristics and cell communication that regulate endometrial receptivity and differentiation, and its disorders in RIF at the window of implantation (WOI) remain rudimentary. Here we characterized the transcriptomes of four major cells in human endometrium from healthy control and RIF patients at single-cell resolution. We discovered the dynamic change characteristics of four major endometrial fibroblast-like cells with different endometrial receptivity, reported a novel pluripotent endometrial glandular epithelial cell with high levels of progesterone receptor and exosomes, and defined a unique ITGA1+CXCR4+ NK cell for connecting endometrial nonimmune cells and immune cell infiltration at the WOI. Additionally, we developed a systematic repository of cell-cell communication for endometrial differentiation and the opening of endometrial receptivity via the ligand-receptor complexes interactions. Our study provides deeper insights into aberrant molecular and cellular characterizations, and the endometrial microenvironmental disorders of RIF patients that are potentially applicable to improve the etiological diagnosis and therapeutics of unexplained RIF.

Project description:Proper decidualization is vital in preparation for a potential embryo receptivity, placentation, menstrual health and subsequent endometrial regeneration. Given the importance of extracellular vesicles (EVs) in intercellular communication, and recently in embryo implantation and indicators of menstrual cycle and fertility, we investigated their role during decidualization. Overall, this study provides an insight into distinct variation in sEV composition depending upon the level of decidualization of endometrial stromal cells, with the signaling potential to coordinate endometrial health ranging from embryo implantation, facilitating placentation and subsequent endometrial regeneration.

Project description:Purpose: We compared endometrial transcriptome profiles during the window of implantation (WOI) between women with and without uterine adenomyosis. Methods: We obtained endometrial biopsies luteinizing hormone (LH)-timed to the WOI from women with sonographic features of adenomyosis (n=10) and controls (n=10). Isolated RNA samples were subjected to RNA sequencing (RNA-seq) and endometrial receptivity classification with a molecular tool for menstrual cycle phase dating (beREADY®, CCHT). RNA-seq data were analysed in the setting of the result of accurate endometrial dating. Results: Out of 20 endometrial samples, 2 were dated to the early receptive phase, 13 to the receptive phase and 5 to the late receptive phase. Comparison of the transcriptomics data from all 20 samples provided 909 DEGs (p<0.05; nonsignificant after adjusted p value) in the adenomyosis group but only 4 enriched pathways (Bonferroni p value < 0.05). The analysis of 13 samples only dated to the receptive phase provided suggestive 382 DEGs (p<0.05; nonsignificant after adjusted p value) in the adenomyosis group, leading to 33 enriched pathways (Bonferroni p value < 0.05). These included pathways were already associated with endometrial biology, such as “Expression of interferon (IFN)-induced genes” and “Response to IFN-alpha”. Conclusion: Accurate endometrial dating and RNA-seq analysis resulted in the identification of altered response to IFN signalling as the most promising candidate of impaired uterine receptivity in adenomyosis.

Project description:In this study, deep sequencing of endometrial RNA samples during early pregnancy were performed using RNA sequencing (RNA-Seq). The changes of genes expressed among three stages (day 12, 18 and 25) of pregnancy were investigated by the multiple comparisons. Analysis of reads, between 1557 and 8951 differentially expressed genes (DEGs) were revealed among different periods of implantation. Expression of selected genes was validated by the use of quantitative real-time RT-PCR. Bioinformatics analysis of differentially expressed genes in the endometrium revealed a number of biological processes and pathways potentially involved in embryo implantation in the pig, most noticeably cell proliferation, regulation of immune response, interaction of cytokine-cytokine receptor, and cell adhesion. This revealed specific gene expression patterns reflecting the different functions of the endometrium on three stages (maternal recognition, conceptus attachment and embryo implantation). This study identified comprehensive transcriptomic profile in the porcine endometrium, it could be a foundation for targeted studies of genes and pathways potentially involved in abnormal endometrial receptivity and embryo loss in early pregnancy.

Project description:MicroRNAs (miRNAs) act as important epigenetic post-transcriptional regulators of gene expression. We aimed to gain more understanding to the complex gene expression regulation of endometrial receptivity by analysing miRNA signature of fertile human endometrium. We used Agilent miRNA arrays to define the miRNA expression pattern in receptive (LH+7, n = 3) vs. pre-receptive (LH<7, n = 4) endometrium from healthy fertile women.
