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:The change in gene expression on the 8th day of gestation was investigated using DNA microarrays. Uterine gene expression of implantation sites was analysed in female mice. Female mice, C57BL/6jXOla129 genetic background were used for experiments. Mice, housed in sterile filter-top cages (3-4 per cage), were acclimatized in a room maintained at 20ºC with a 12-h light-dark fr four months. Two groups were established: a) The control group and b) homozygous Cbs deficient mice and sacrificed at the eight day post-coitum.

Project description:Trophoblast Invasion is a complex mechanism that involves several genes and processes that are exquisitely regulated by the mother. Functional genomics has shown that immunomodulatory and proliferation are two essential key processes involved. Adult virgin B6CBA F1/J female mice were mated with CD1 fertile males to induce pregnancy (day 0=vaginal plug). Mice were sacrificed by cervical dislocation. Implantation and inter-implantation sites were divided by sharp dissection 6.5 days post-coitum (dpc) (n=3 mice). Uterine segments included uterine myometrium, stroma, and epithelium. Inter-implantation decidua (ID) were collected and Implantation sites also were divided by sharp dissection to separate extra-embryonic tissue (ET) from surrounding decidua (SD). From the embryo, only the invasive trophoblast formed by the ectoplacental cone was studied too.

Project description:Current knowledge of the molecular regulation of the blastocyst implantation event has been largely derived from studies in the mouse that requires ovarian estrogen for initiation of the implantation event. However, there are species such as the hamster, guinea pig, pig, horse, rhesus monkey and perhaps the human where the blastocyst implantation event initiates only in the progesterone-primed uterus. Despite this fundamental difference in the requirement of ovarian hormones in initiating blastocyst implantation among species, efforts to identify gene networks relevant for the blastocyst implantation event in progesteroneM-bM-^@M-^Sdependent species are limited. In this study, cDNA prepared from RNAs of day 5 blastocyst implantation and interimplantation sites were hybridized with mouse and human oligonucleotide microarray platforms to discern the transcriptional networks underlying the regulation of blastocyst implantation in hamsters. Compared with the inter-implantation site, blastocyst implantation sites showed upregulation and downregulation of a sizable number of genes by both cross-species arrays.The merit of the cross-species hybridization and reliability of the identified up- and down-regulated genes at the implantation sites were validated by detecting differential expression of a few randomly selected genes from both arrays by real-time PCR. Function gene ontology and pathway analysis revealed that differentially expressed genes are associated with several biological events and molecular pathways that are likely to be taking place at the blastocyst implantation site. This is the first study that identified the differential gene expression profile at the blastocyst implantation site of the hamsters, and revealed molecular pathways that are possibly associated with the progesterone-dependent blastocyst implantation process. We used microarrays to detail the expression differences in hamster implantation and interimplantation sites. Total RNAs were prepared from the hamster day 5 blastocyst implantation and interimplantation sites. Three sets of RNAs were isolated from three different animals and were subjected to microarray analysis using Affymetrix mouse and human array platforms.
