Project description:Endometriosis is a common disease seen by gynecologists. Clinical features involve pelvic pain and unexplained infertility. Although endometriosis is pathologically characterized by endometrial tissue outside the normal uterine location, endometriosis is otherwise not easily explained. Endometriomas, endometriotic cysts of the ovary, typically cause pain and distortion of pelvic anatomy. To begin to understand the pathogenesis of endometriomas, we carried out transcriptome:microRNAome analysis of endometriomas and eutopic endometrium, using gene expression arrays and next generation small RNA sequencing technology. Keywords: two group comparison Patients undergoing surgery for endometriomas, suspected endometriosis, pelvic pain, abnormal uterine bleeding, pelvic organ prolapse, or uterine leiomyomas were approached for participation. After informed consent, the patients underwent scheduled surgical procedure. Tissues were collected either as cyst wall of endometrioma or endometrial curettage of hysterectomy specimen and placed directly into RNALater (Ambion, Austin, TX) and eventually frozen at -80?C. Samples were designated as endometriomas or non-endometriosis control endometrium based on surgical pathology reports. Total RNA was isolated from frozen tissue. High quality RNA was subjected to Illumina’s Human WG-6 version 2.0 BeadChips (Illumina). . *** This Series represents the transcriptome component of the study. ***

Project description:Endometriosis, a benign inflammatory disease whereby endometrial-like tissue grows outside the uterus, is a risk factor for endometriosis-associated ovarian cancers. In particular, ovarian endometriomas, cystic lesions of deeply invasive endometriosis, are considered the precursor lesion for ovarian clear-cell carcinoma (OCCC). To explore the transcriptomic landscape, OCCC from women with pathology-proven concurrent endometriosis (n = 4) were compared to benign endometriomas (n = 4) by bulk RNA and small-RNA sequencing.

Project description:Gene expression profiling of primary stromal cell cultures isolated from human endometrium and ovarian endometriosis. Samples are derived from the endometrium of 6 healthy patients and the endometriomas of 6 diseased patients. The results indicate the gene expression differences between these two cell populations. Stromal cells were obtained from human normal endometrial tissues and ovarian endometriomas. The tissues were digested enzymatically, and pure stromal cell populations were established.

Project description:We profiled transcriptomes of >370,000 individual cells from endometriomas (n=8), endometriosis (n=28), eutopic endometrium (n=10), unaffected ovary (n=4) and endometriosis-free peritoneum (n=4) to create a cellular atlas of endometrial-type epithelial cells, stromal cells, and microenvironmental cell populations across tissue sites.

Project description:Endometriosis is a common gynecological disorder characterized by pain and infertility, where the lesions disseminate everywhere in the body with a preference for the pelvis. In that, it could be regarded as a âbenign metastatic diseaseâ, since its issue is not fatal. However, the molecular bases of this intriguing clinical condition are not well known. The objective of this study is to characterize the transcriptome differences between eutopic vs ectopic endometrium with a special interest in pathways involved in cancerogenesis. We performed two hybridizations in technical replicate on highly specific long oligonucleotides microarrays (NimbleGenâ¢), with cDNA prepared from 6-patients pools, where the same patient provided both eutopic and ectopic endometrium (endometriomas). In order to confirm the expression microarrays data, qRT-PCR validation was performed on 12 individuals for 20 genes. Over 8,000 transcripts were significantly modified (more than twice) in the lesions corresponding to 5,600 down- or up-regulated genes. These were clustered through DAVID Bioinformatics Resources into 55 functional groups. The data are presented in a detailed and visual way on 24 KEGG pathways implemented with induction ratios for each differentially expressed gene. An outstanding control of the cell cycle and a very specific modulation of the HOX genes were observed and provide some new evidence on why endometriosis only very rarely degenerates into cancer. The study constitutes a noteworthy update of gene profiling in endometriosis, by delivering the most complete and reliable list of dysregulated genes to date.

Project description:Epigenetic silencing of Steroidogenic Factor 1 (SF1) is lost in endometrial tissue in endometriosis and this is hypothesized to result in de novo local steroidogenesis favoring growth and inflammation. The goal of this study was to evaluate the endometrial specific transcriptional and functional role of SF1. Expression of SF1 was robustly increased in cultures established from stromal fibroblasts isolated from endometriomas (OsisHESC) over endometrial stromal cells isolated from eutopic sites in healthy proliferative phase endometrial biopsies (HESC). In order to evaluate the role of SF1 in the regulation of genes in fibroblast isolated from human endometriomas, OsisHESC were transfected with scrambled siRNA (siNT) or siRNA targeting SF1 (siSF1).
