Project description:Polycystic ovary syndrome (PCOS) is a common gynaecological disorder, characterised by elevated circulating androgens and increased expression of androgen receptor (AR) and by downregulation of Wilms Tumour 1 in the endometrium, The objectives of this study are: 1) Understand the functional role of WT1 in regulating decidualization response in healthy endometrial tissue, and 2) understand how interactions between aberrant WT1 and AR expression in PCOS patients result in dysregulation of deciduallization processes

Project description:Polycystic ovary syndrome (PCOS), one of the most common endocrinal diseases among reproductive-aged women, is characterized by hyperandrogenemia, chronic oligo/anovulation and polycystic ovarian morphology. In this research, we presented microarrays to identify the differential expressed protein-coding genes and lncRNAs expression profile in the endometrium during the window of implantation between the PCOS and healthy subjects.

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:To reveal microRNAs expression differences in cumulus cells between polycystic ovary syndrome (PCOS) and non-PCOS women. miRNAs expression profile of the cumulus cell samples with PCOS and non-PCOS were determined by Affymetrix miRNA 2.0. Six pooled RNAs from CC samples (three PCOS and three non-PCOS pooled RNAs) were separately analyzed on 6 GeneChip miRNA 2.0 Array (miRBase V15)

Project description:Polycystic ovarian syndrome (PCOS) is characterized by hyperandrogenism, irregular ovulation and polycystic ovaries. In the present study, we utilized integrated analysis of whole transcriptome and DNA methylome by reduced representation bisulfite sequencing (RRBS) and RNA sequencing (RNA-seq) of the fetal side of placenta in women with PCOS. A cluster of neural function related genes, such as LIN7A and MAP1B, were identified with integrative analysis of methylome and transcriptome. Inflammatory disease and response process were spotlighted with GO enrichments analysis of differentially transcriptional gene cluster in PCOS, and the cellular growth and the development and function of nervous and endocrine system were also closely related to PCOS. With respect to neural function, the enriched GO terms in differential expressed gene cluster of PCOS group involved brain development, the proliferation and differentiation of neural precursor cell, neuron and neuroblast. Consistently, the enriched GO terms in differential methylated gene cluster of PCOS group were associated with neuropeptide and synaptic transmission, as well as cognition and learning or memory. As the gene expression changes in hypothalamus and hippocampus probably result in long standing neurobehavioural consequences in rodents, we conducted a global analysis of transcriptomic data of F1 pubertal female rats born to PCOS rats.

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.

Project description:Polycystic ovary Syndrome (PCOS) is a heterogeneous endocrine disorder that shows evidence of genetic predidposition among affected individuals. We have utilized the Microarray data from granulosa cells of normal and PCOS women for network construction. Human granulosa cells were isolated from ovarian aspirates from normal and PCOS women undergoing IVF and for each sample, RNA was extracted and hybridized to an Affymetrix GeneChip.
