Project description:To detect the gene profiles in receptive uterus, two independent uteri are collected from pregnant day 4 mice and subjected to RNA-Seq. After aligned to mouse mm9 by Tophat2, RPKM value was calculated by Edger. Our results show that HMGB1 is one of the most abundant gene in the whole HMG family. The expression of HMGB1 was further confirmed by qPCR, ISH and immunofluorescence. The expression of HMGB1 was found expressed in very cells, indicating the essential role of HMGB1 for reproduction. This RNA-Seq data provides fundamental information for our further physiological study of HMGB1.

Project description:Our preliminary study revealed that the homeobox transcription factors, Msx1 and Msx2, are expressed in the mouse uterus during early pregnancy. Further, conditional deletion of Msx1 and Msx2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Msx1Msx2 in the uterus, we performed gene expression profling of uterine stromal cells isolated from Msx1Msx2-null mice and the corresponding controls on day4 of pregnancy (the time of implantation). The microarray results revealed elevated expression of mRNAs corresponding to several members of the fibroblast growth factor family and Wnts in uterine stroma of Msx1Msx2-ablated mice. We performed conditional ablation of Msx1Msx2 in the mouse uterus using the PRcre mouse model. we isolated uterine stromal cells from day4 pregnant mice (n=5 for each genotype), purified total RNA from these cells, pooled these samples and then hybridized to high density affymetrix microarrays.

Project description:Our previous study revealed that the basic helix-loop-helix transcription factor Hand2 is a downstream target of progesterone signaling in mouse uterine stroma at the time of implantation. Further, conditional deletion of Hand2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Hand2 in the uterus, we performed gene expression profling of uterine stromal cells isolated from Hand2-null mice and the corresponding controls on day4 of pregnancy (the time of implantation). The microarray results revealed elevated expression of mRNAs corresponding to several members of the fibroblast growth factor family in uterine stroma of Hand2-ablated mice. These factors act as paracrine mediators of mitogenic effects of estrogen on the epithleium. Thus, Hand2 is a critical regulator of the uteirne stromal-epithelial communication that directs proper steroid regulation conducive for establshment of pregnancy. We performed conditional ablation of Hand2 in the mouse uterus using the PRcre mouse model. As Hand2 expression is restricted to stromal comaprtment, we isolated uterine stromal cells from day4 pregnant mice (n=5 for each genotype), purified total RNA from these cells, pooled these samples and then hybridized to high density affymetrix microarrays.

Project description:Our study revealed that hypoxia inducible factor 2 alpha, Hif2 alpha, is a downstream target of estrogen signaling in mouse uterine stroma at the time of implantation. Further, conditional deletion of Hif2 alpha in mouse uterus leads to infertility due to impaired epithelial remodeling at the time of implantation. To identify the downstream targets of Hif2 alpha in the uterus, we performed gene expression profiling of uterine stromal cells isolated from Hif2 alpha-intact and -null mice on day 5 of pregnancy, overlapping the window of implantation. The microarray results revealed altered expression of mRNAs corresponding to factors involved in protein trafficking in uterine stroma of Hif2 alpha-ablated mice. These factors mediate crosstalk between uterine storma and epithelial cells to promote epithelial remodeling and implantation. Thus, Hif2 alpha regulates embryo implantation by controlled trafficking of secretory granules during early pregnancy.

Project description:The peripheral circadian oscillator plays an essential role in synchronizing local physiology to operate in a circadian manner via regulation of the expression of clock-controlled genes. In the murine uterus, the endometrial stromal cells undergo proliferation and differentiation into decidual cells in response to ovarian steroids and blastocyst implantation at the early stage of pregnancy. The circadian clock genes are attenuated in the decidualizing cells only 2 days after implantation. The present study aimed to evaluate the circadian rhythms of clock genes and clock-controlled genes expressed in the rat uterus endometrial stromal cells (UESCs) during the stage of implantation. The real-time monitoring system of Per2 promoter activity was employed to precisely evaluate the generation of circadian rhythms in the UESCs prepared from transgenic rats constructed with mouse Per2 promoter-destabilized luciferase reporter gene (Per2-dLuc). During monitoring Per2-dLuc oscillation after synchronization with dexamethasone, total RNA was isolated from the cultured UESCs at four-time points (6-h interval) in the first to second phases and cDNA was synthesized. cRNA was synthesized from the double strand cDNA and hybridized on a DNA microarray. RT-qPCR was performed to confirm the expression of core clock genes revealed by DNA microarray analysis. Several clock genes such as Bmal1, Rev-erbα, and Per2 displayed significant rhythms. Of 12,252 genes showing significantly expression, 7,235 genes displayed significant alterations (p < 0.05). These genes were related to growth factors, transcription factors, receptors, channels, and enzymes. Some candidates as clock-controlled genes were evaluated by using RNA interference to Bmal1 mRNA. Down-regulation of Igf1 gene expression was observed by Bmal1 silencing, whereas the expression of Inhβa, Fas, and Caspase3 were significantly increased. These results indicate that clock-controlled genes are up- or down-regulated in rat UESCs during the stage of decidualization. DNA microarray analysis coupled with RNA interference will be helpful to understand the physiological roles of some oscillating genes in blastocyst implantation and placenta formation. The circadian clock positively or negatively regulates the expression of clock-controlled genes, including growth factors and apoptosis-related factors. To search the clock-controlled genes expressed during the period of implantation, we analyzed the clock genes and clock-controlled genes expressed in cultured uterus endometrial stromal cells prepared from pregnant rats at the stage of implantation using DNA microarray technology. We used transgenic rats constructed with mouse Per2 promoter-destabilized luciferase (Per2-dLuc) reporter gene to precisely adjust the time of gene expression. In addition, several genes of significantly expressed genes including growth factor genes and apoptosis-related genes were analyzed using RNA interference to Bmal1 mRNA whether these were controlled under circadian clockwork.

Project description:In present, interspecies cloning and interspecies-pregnancy were studied for endangered species rescue. However, the low implantation and survival ratio, spontaneous abortion, and unknown reason embryos absorption are the common and difficult problems of interspecies-pregnancy. In order to discover the mechanism of interspecies-pregnant failure and find ways to overcome the xeon-pregnant obstacles, we chosen the rat embryos pregnant in mouse uterus as a interspecies-pregnancy model. Three groups were set, mouse embryos to mouse recipients (MM) as control group, rat embryos to mouse recipients (RM), and rat and mouse embryos to mouse recipients together (RMM) as experiment groups. The former studies showed that rat embryos live no longer than day 7 of mouse pregnancy (D7). Our results showed that rat embryos survived to D7, and still existed to day 9 of mouse pregnancy (D9) in RM group. Surprisingly, the rat embryos survived to day 13 of the mouse gestation (D13) in RMM group. Microarray analysis was used to detect the global-gene expression profile changes of the whole implantation sites among the three groups at D7 and D9. By this way, we screened out the genes promoting the implanted rat embryos development in a mouse uterus which helped the rat embryos survive to D13 in RMM group compared with RM group, and the genes hindering the rat embryos development in a mouse uterus which prevented rat embryos living longer than D7 in RM group and D13 in RMM group compared with MM group. These findings provide insights into the mechanism of interspecies pregnant failure and new idea for interspecies pregnant studies. Experiment Overall Design: microarray was use to screen the genes among the day 7 and day 9 implantation sites of rat embryos implantation sites in a mouse uterus between rat embryos transfer to mouse recipients and rat embryos transfer to mouse recipients with mouse embryos. The mouse day7 and day 9 embryos implantation sites were use as control. Experiment Overall Design: totally 6 samples were analyzed, each samples two replications (one of them had three replications).
