Project description:Objective: To study the potential effect of COVID-19 on the endometrium of affected symptomatic women. Design: Preliminary study of the endometrial transcriptomes in women with COVID-19 through RNA sequencing. Setting: Hospital and university laboratories. Subjects: Women with COVID-19 lacking SARS-CoV-2 infection in endometrial tissue. Intervention/Exposure: Endometrial biopsy collection. Main outcomes measures: Endometrial gene expression and functional analysis of patients with COVID-19 versus uninfected individuals. Results: COVID-19 systemic disease alters endometrial gene expression in 75% of women, with patients exhibiting a preponderance of 163 up-regulated (e.g., UTS2, IFI6, IFIH1, BNIP3) and 72 down-regulated genes (e.g., CPZ, CDH3, IRF4) (FDR<0.05). A total of 161 dysregulated functions (36 up-regulated and 125 down-regulated) were typically enriched in COVID-19 endometria, including upregulation in pathways involved in response to virus and cytokine inflammation, highlighting upregulation of a COVID-19 response pathway. Conclusion: COVID-19 affects endometrial gene expression despite the absence of SARS-CoV-2 particles in endometrial tissues.

Project description:Endometrial cancer represents the most frequent gynecologic malignant disease. Although several genetic alterations have been associated with increased risk, to date diagnosis and prognosis still rely on morphological features of the tumor, such as histological type, grading and invasiveness. As molecular-based classification is desirable for optimal treatment and prognosis of these cancers, , we explored the potential of lncRNAs as molecular biomarkers. To this end, we first identified by RNA sequencing (RNA-Seq) a set of lncRNAs differentially expressed in cancer vs normal endometrial tissues, a result confirmed also by analysis of RNA-Seq data of normal and cancerous endometrium from The Cancer Genome Atlas (TCGA). A significant association of a subset of these differentially expressed lncRNAs with tumor grade was then determined in 405 TCGA endometrial cancer profiles. Integrating endometrial cancer-specific expression profiles of long and small non-coding RNAs a functional association network was then identified. These results described for the first time a functional ‘core’ network, comprising small and long RNAs, whose deregulation is associated with endometrial neoplastic transformation, representing a set of cancer biomarkers that can be monitored and targeted for diagnosis, follow-up and therapy of these tumors.

Project description:<p>Endometrial diseases are common gynecological diseases that disorder women of childbearing age and perimenopausal women, including endometrial polyps (EP), endometrial cancer (EC), and endometrial hyperplasia (EH). Clinically, biopsy or imaging methods are usually used to screen and diagnose endometrial diseases, but due to their invasiveness and heterogeneity, a noninvasive, convenient, objective and accurate biomarker is needed for the differential diagnosis of EP and EC or EH. In the present study, serum samples from 396 patients with endometrial disease and 225 healthy volunteers were analyzed by UPLC-Q-TOF/MS non-targeted lipidomics. A combination of multivariate (Orthogonal partial least-squares discriminant analysis) and univariate (Student t-test) analyses were used to identify and qualify 6, 8, and 7 potential biomarkers in serum from patients with EP, EC, and EH, respectively. With the aid of logistic regression algorithm and receiver operating characteristic (ROC) curve analysis, A biomarker panel including four specific EP biomarkers, 6-Keto-PGF1α, PA(37:4), LysoPC(20:1) and PS (36:0), had good classification and diagnostic ability in distinguishing EP from EC or EH. The biomarker panel can be used as a rapid diagnostic method to assist imaging examination to effectively differentially diagnose endometrial diseases, and provide a reference for clinicians in the identification and diagnosis of endometrial diseases. </p>

Project description:Endometriosis is an inflammatory disease and bone marrow-derived cells are abundant in endometriotic lesions and in the peritoneal fluid of women with the disease. This study tested the hypothesis that reciprocal communication occurs between macrophages and cultured human endometrial stromal cells and that this communication contributes to the pathology of endometriosis. Changes in gene expression elicited by exposure to factors secreted by the opposing cell type were measured by DNA microarray to test this hypothesis. 716 named genes were differentially expressed in cultured endometrial stromal cells in response to factors secreted by macrophages. Genes that were up-regulated included IL8/CXCL8, MMP3, phospholamban, CYR61/CCN1, CTGF/CCN2, tenascin C, and NNMT, whereas integrin alpha 6 was down-regulated. In contrast, 15 named genes were differentially expressed in macrophages in response to factors secreted by cultured endometrial stromal cells. The data document reciprocal communication between macrophages and endometrial stromal cells and suggest that interaction with macrophages stimulates the expression of genes in endometrial stromal cells that contribute to migration, adhesion, invasion, neovascularization and mitosis of endometrial cells that may support the establishment of endometriosis.

Project description:This study focuses on the potential of detecting endometrial cancer based on the proteins and peptides expressed in cervico-vaginal fluid.Sequential window acquisition of all theoretical mass spectra (SWATH-MS), an accurate and reproducible platform for analysing biological samples, offers a technological advance for biomarker discovery due to its reproducibility, sensitivity and potential for data re-interrogation. SWATH-MS requires a spectral library in order to identify and quantify peptides from multiplexed mass spectrometry data.Here, we present a spectral library of thousands of proteins in the cervico-vaginal fluid of women with or at risk of endometrial cancer. Pooled cervico-vaginal fluid samples from 19 women, comprising of 9 endometial cancer cases(both endometriod and non-endometriod), 3 atypical hyperplasias and 7 controls (symptomatic post-menopausal women with no evidence of endometrial cancer) were used for library generation. We have combined these data with a library of over 6,000 proteins generated based on mass spectrometric analysis of two endometrial cancer cell lines This important resource will enable the identification of endometrial cancer biomarkers in cervico-vaginal fluid and advances our knowledge of the role of proteomics in endometrial cancer detection.

Project description:The objectives of the present study were to determine whether obesity impacts human decidualization and the endometrial control of trophoblast invasion (both of which are required for embryo implantation) and evaluate the potential involvement of endometrial extracellular vesicles (EVs) in the regulation of these physiological processes. Using primary human cell cultures, we first demonstrated that obesity is associated with significantly lower in vitro decidualization of endometrial stromal cells (ESCs). We then showed that the trophoblastic cell line’s invasive ability was greater in the presence of conditioned media from cultures of ESCs from obese women. Using mass-spectrometry-based quantitative proteomics, we found that EVs isolated from uterine supernatants of biopsies from obese women (vs. nonobese women) presented a molecular signature focused on cell remodeling and angiogenesis. Lastly, the results of functional assays indicated that supplementation of the culture medium with EVs from nonobese women can rescue (at least in part) the defect in in vitro decidualization described in ESCs from obese women. Lastly, the addition of endometrial EVs from obese women (vs. nonobese women) was associated with significantly greater invasive activity by HTR-8/SVneo cells. In conclusion, our results provided new insights into the endometrial EVs’ pivotal role in the poor uterine receptivity observed in obese women.

Project description:Immune system cells and cells of the endometrium have long been proposed to interact in both physiological and pathological processes. The current study was undertaken to examine communication between cultured monocytes and endometrial stromal cells and also to assess responses of endometrial stromal cells to treatment with estradiol (E) in the absence and presence of medroxyprogesterone acetate (P). A telomerase-immortalized human endometrial stromal cell line (T-HESC) and the U-937 monocyte cell line were used. T-HESC were treated with E ± P ± monocyte conditioned medium; U-937 were treated ± T-HESC conditioned medium. Gene expression in response to treatment was examined by DNA microarray. Bi-directional communication, as demonstrated by changes in gene expression, clearly occurred between U-937 monocytes and T-HESC endometrial stromal cells.
