Project description:Implantation is crucial for placental development which directly impacts fetal growth and pregnancy success with possible consequences on post-natal health. We postulated that early perturbations of the conceptus-maternal environment communication may alter the endometrium physiology that could account for the final reproductive outcome. Using cattle as an animal model, we compared gene expression profiles of the endometrial caruncular and intercaruncular areas during the critical period of implantation in three types of pregnancies: artificial insemination (AI), in vitro fertilization with embryo transfer (IVF-ET) or somatic cell nuclear transfer (SCNT). Less than 35% of the differentially expressed genes were found to be common between AI, IVF-ET, and SCNT conditions. Compared to AI, numerous biological functions and several canonical pathways and genes were found to be significantly affected in IVF-ET or SCNT, with a major impact on metabolism and immune function in SCNT. Our data show that the endometrium can fine-tune its physiology and could be considered as a biological sensor in response to pregnancy manipulations. Determining the limits of the endometrial plasticity should bring new insights on the contribution of the maternal compartment to the pregnancy outlet.

Project description:Objective: The etiology of PCOS is mostly unknown. Existing data support both genetic and environmental factors in its pathogenesis. Design: Prospective case - control study. Setting: University Hospital. Patients: 25 patients undergoing IVF-ICSI treatment. Intervention: Genome-wide oligonucleotide microarray technology was used to study differential gene-expression patterns of cultured human cumulus cells from IVF patients divided into 4 groups according to disease state (PCOS vs. Control) and BMI (Obese vs. Lean). Results: Two differential PCOS gene expression profiles were established: Lean-Type was formed by comparing PCOS lean (PL) vs. non-PCOS lean (NL) individuals; Obese-Type was formed by comparing PCOS obese (PO) vs. non-PCOS (NO) obese patients. Conclusions: Different molecular pathways are associated with PCOS in Lean and Obese individuals, as demonstrated by gene expression profiling of cumulus cells. Our findings provide insights into the molecular pathogenesis of PCOS. We used microarrays to study the gene expression of human cultured cumulus cells. We compared the genes expression of lean PCOS, Obese PCOS, lean controls and obese controls. Different molecular pathways are associated with PCOS in Lean and Obese patients. Experiment Overall Design: Cumulus cells obtained from woman undergoing IVF/ICSI. Following oocyte retrieval, cumulus cells were stripped from the oocyte, in preparation for the ICSI process, with a micropipette. After 48h in culture the cumulus cells were collected for RNA extraction and hybridization on Affymetrix microarrays. We compered the expression profile of 4 groups - lean PCOS, obese PCOS, lean controls and obese controls.

Project description:Implantation is crucial for placental development whose quality will directly impact fetal growth and pregnancy success with possible consequences on post-natal health. We postulated that early perturbations of the conceptus-maternal environment communication may alter the endometrium physiology that could account for the final reproductive outcome. Using cattle as an animal model, we compared gene expression profiles of the endometrial caruncular and intercaruncular areas at implantation in three types of pregnancies, namely artificial insemination (AI), in vitro fertilization with embryo transfer (IVF-ET) or somatic cell nuclear transfer (SCNT). Less than 35% of the differentially regulated genes were found to be common between AI, IVF-ET, and SCNT conditions. Compared to AI, numerous biological functions and several canonical pathways and genes were found to be significantly affected in IVF-ET or SCNT, with a major impact on metabolism and immune function in SCNT. Our data show that endometrium can fine-tune its physiology and could be considered as a biological sensor in response to pregnancy manipulations. Determining the limits of the endometrial plasticity should bring new insights on the contribution of the maternal compartment to the issue of pregnancy. Keywords: Fluorescence Microarray 30 samples

Project description:Context: Endometrium in polycystic ovary syndrome (PCOS) presents altered gene expression indicating progesterone resistance and predisposing to reduced endometrial receptivity and endometrial cancer. Objective: We hypothesized that an altered endocrine/metabolic environment in PCOS may result in an endometrial M-bM-^@M-^\disease phenotypeM-bM-^@M-^] affecting the gene expression of different endometrial cell populations, including stem cells and their differentiated progeny. Design and setting: A prospective study conducted at an academic medical center. Patients and Main Outcome Measures: Proliferative phase endometrium was obtained from 6 overweight/obese PCOS (NIH criteria) and 6 overweight/obese controls. Microarray analysis was performed on fluorescence-activated cell sorting (FACS)-isolated endometrial epithelial cells (eEP), endothelial cells (eEN), stromal fibroblasts (eSF) and mesenchymal stem cells (eMSC). Gene expression data were validated using microfluidic Q-RT-PCR and immunohistochemistry (IHC). Results: The comparison between eEPPCOS and eEPCtrl showed dysregulation of inflammatory genes and genes with oncogenic potential (CCL2, IL-6, ORM1, TNAIFP6, SFRP4, SPARC). eSFPCOS and eSFCtrl showed upregulation of inflammatory genes (C4A/B, CCL2, ICAM1, TNFAIP3). Similarly, in eMSCPCOS vs. eMSCCtrl the most upregulated genes were related to inflammation and cancer (IL-8, ICAM1, SPRR3, LCN2). IHC scoring showed increased expression of CCL2 in eEPPCOS and eSFPCOS compared to eEPCtrl and eSFCtrl and IL-6 in eEPPCOS compared to eEPCtrl. Conclusions: Isolated endometrial cell populations in women with PCOS showed altered gene expression revealing inflammation and pro-oncogenic changes, independent of BMI, especially in eEPPCOS and eMSCPCOS, compared to controls. The study reveals an endometrial M-bM-^@M-^\disease phenotypeM-bM-^@M-^] in women with PCOS with potential negative effects on endometrial function and long-term health. Proliferative phase endometrium was obtained from 6 overweight/obese PCOS (NIH criteria) and 6 overweight/obese controls. Microarray analysis was performed on fluorescence-activated cell sorting (FACS)-isolated endometrial epithelial cells (eEP), endothelial cells (eEN), stromal fibroblasts (eSF) and mesenchymal stem cells (eMSC). Tissue samples were obtained through the National Institute of Health (NIH)/University of California, San Francisco (UCSF), Human Endometrial Tissue and DNA Bank in accordance with the guidelines of the Declaration of Helsinki. Informed consent was obtained from all participants in the UCSF Center for Reproductive Health, and the study was approved by the UCSF Committee on Human Research. The clinical summary of the study participants is shown in Table 1. Eleven proliferative phase endometrial biopsies (Pipelle, Cooper Surgical Shelton, Connecticut) and one curettage specimen were collected from over-weight (Body Mass Index [BMI, kg/m2] M-bM-^IM-% 27 < 29.9; n=1) and obese (BMI M-bM-^IM-% 30; n=5) women with PCOS (age 30.5M-BM-1 2.1 yrs, BMI 34.13M-BM-1 2.2, NIH criteria (17) and overweight (n=2) and obese (n=4) control women (age 36.50M-BM-11.70 yrs, BMI 35.73M-BM-13.96). All PCOS subjects had normal 17-hydroxyprogesterone, prolactin and thyroid hormone levels. Control samples were obtained from healthy volunteer and women undergoing benign gynecological surgery. All controls reported menstrual cycles with regular interval (25-35 days) and no clinical evidence of having PCOS. Neither PCOS nor control subjects were exposed to hormonal medications for at least 2 months prior to tissue sampling and were confirmed not pregnant.

Project description:CONTEXT Nowadays, the molecular mechanisms involved in endometrial receptivity and implantation are still not clear. OBJECTIVE The gene expression of human endometrium of patients undergoing an IVF treatment with GnRH antagonists/rec-FSH was studied. CONCLUSIONS COX-2 has been extensively studied as a crucial fertility element in both knock-out mice and human. It appears that increased expression of COX-2 and/or SCGB1D2 on the day of oocyte retrieval in GnRH antagonist/rec-FSH stimulated cycles coincides with a lower probability of achieving a clinical pregnancy in this cycle.
