Project description:We report the expression of mRNA and lncRNA in mouse uterus between periods of embryo implantation and labor by high-throughput seq. By the seq analysis of mRNA and lncRNA expression, 1971 differentially expressed (DE) mRNAs and 1543 DE lncRNAs were found between E0.5 and E4.5 at the embryo implantation stage, while 1149 DE mRNAs and 410 DE lncRNAs were found between E15.5 and E18.5 at the labor stage. While 117 DE mRNAs and 19 DE lncRNAs were commonly expressed between the two stages. This study provides a basic gene expression of altered pregnancy status.

Project description:The aim of this study was to examine differential gene expression profile in mouse uterus on day 5 of pregnancy between implantation sites and inter-implantation sites. There are 104,520 tags sequenced and acquired, 51,306 for non-implantation site, and 53,214 for implantation site. Keywords: Implantation, Uterus, Differential gene expression, Implantation sites and inter-implantation sites were isolated from the mouse uteri on day 5 of pregnancy from at least 20 mice. Implantation sites were identified by tail-vein injection of 0.1 ml of 1% Chicago blue 5 min before sample collection. SAGE analysis was used to examine differential gene expression in mouse uterus during embryo implantation.

Project description:We compared gene expression profiles in uterus before and after onset of labor. Gene expression profiles were compared between functionally distinct areas of the human uterus: the fundus, lower segment and the cervix in samples obtained before labor and during labor.

Project description:Embryo implantation in the rabbit is unique in that a typical fusion type of implantation is employed, in which trophoblast cells adhere and fuse to the apical surface of uterine epithelial cells. In the present study, we analyzed global gene expression changes in the rabbit uterus during embryo implantation by using RNA-seq.

Project description:Embryo implantation is a complex process which involves biochemical and physiological interactions between an implantation-competent blastocyst and a receptive uterus. However, the exact biochemical changes of uterine fluid, uterus, and plasma during peri-implantation remain unclear. This study aims to characterize the biochemical and metabolic changes that occur during the peri-implantation period of early pregnancy, using mice as an animal model. Gas chromatography-mass spectrometry was used to analyze the metabolite profiles of the uterus, uterine fluid, and maternal plasma at pre-implantation and implantation. The multivariate analyses, ANOVA and Tukey's HSD test, were applied to detect significant changes in metabolites and metabolic pathways. The metabolic networks were reconstructed in silico based on the identified metabolites and KEGG metabolic framework. Between pre-implantation day 1 and day 4, dramatic metabolic changes were observed in the uterine fluid that could be important for blastocyst development and protection against the harsh uterine environment. Palmitoleic acid, fumaric acid, and glutaric acid changed levels at day 4 in the uterus, suggesting that they may be associated with endometrial receptivity. Both the uterus and maternal plasma showed profound changes in cellular metabolism at the early implantation period, including upregulation of branched-chain amino acids and intermediates of one-carbon metabolism, an upregulation of glyoxylate and dicarboxylate metabolism, and downregulation of aerobic respiration; all of which could be involved in the regulation of the maternal-fetal interface, alternative nutrient utilization, and energy preservation for implantation as well as later placentation and fetal development to ensure successful embryo implantation.

Project description:Early gestational loss occurs in ~20% of all clinically recognized human pregnancies and is a significant cause of morbidity. Either embryonic or maternal defects can cause loss, but a functioning and receptive uterine endometrium is crucial for embryo implantation. The SWI/SNF remodeling complex containing PBRM1and BRG1 is essential for implantation of the embryonic blastocyst on the wall of the uterus in mice. Although pre-implantation development is unaffected, conditional ablation of Pbrm1 in uterine stromal cells disrupts progesterone pathway and uterine receptivity. Hand2 is a bHLH transcription factor required for embryo implantation. We report a new enhancer of Hand2 in stromal cells that requires PBRM1 for epigenetic histone modifications and coactivator recruitment. In Pbrm1cKO mice, perturbations at the enhancer site compromised Hand2 transcription, disrupts the fibroblast growth factor signaling pathway and prevents normal Stromal- Epithelial crosstalk and embryo implantation. The resultant mutant female mice are infertile and provide insight into potential causes of early pregnancy loss in humans.

Project description:In this study, a genetically repressed VEGF mouse model was used to analyze uterus transcriptome at G2.5 (gestation day 2.5) by Solexa/ Illumina’s digital gene expression (DGE) system. 831 uterus-specific and 2398 VEGF regulated genes were identified. Gene ontology analysis indicated that genes actively involved in uterus development were members of collagen biosynthesis, cell proliferation and cell apoptosis. Uterus-specific genes were enriched in activities of phosphatidyl inositol phosphate kinase, histone H3-K36 demethylation and protein acetylation. Among VEGF regulated genes, up-regulated genes were associated with RNA polymerase III activity while down-regulated genes were strongly associated with muscle development.Comparable numbers of antisense RNA transcripts were also identified. Expression levels of the antisense RNAs were found tightly correlated with their sense expression levels, an indication of possibly non-specific transcripts generated around the active promoters and enhancers. The antisense RNAs with exceptionally high or low expression levels and the antisense RNAs under VEGF regulation were also identified. These transcripts may be important candidates in regulation of uterus development. This study provides a global survey on genes and antisense transcripts regulated by VEGF in the pre-implantation stage. Results will contribute to the further studies of candidate genes and pathways in regulating implantation process and related diseases. Uteri mRNA profiles of G2.5 VEGF-normal (Dox+) and VEGF-repression (Dox-) were generated by Solexa/ Illumina’s digital gene expression (DGE) system.
