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:Pregnancy loss is the most common complication of human pregnancy. Recurrent early pregnancy loss (REPL) has multiple etiologies, including endometrial dysregulation leading to “suboptimal” implantation. Although the implantation process is tightly regulated in Eutherian (placental) mammals, the molecular factors contributing to dysregulated endometrial gene expression patterns in women with REPL are largely unknown. We hypothesized that genes that gained novel expression in the endometria of mammals that evolved in the Eutherian stemlineage, coincident with the evolution of pregnancy, are likely essential for establishment and maintenance of normal pregnancy and are, therefore, good candidates for genes whose expression may be dysregulated in disorders such as REPL. To test this hypothesis, we took an evolutionary forward genomics approach to characterize gene expression profiles of midsecretory endometria from women with REPL associated with abnormal endometria based either on histology or molecular expression of cyclin E. We identified 58 genes that were differentially expressed (P<0.001) between women with out-of-phase histological dating vs normal histology, and 81 genes that were differentially expressed (P<0.001) between women with abnormally elevated cyclin E levels vs normal cyclin E. Remarkably, genes that were recruited into endometrial expression during the evolution of pregnancy in Eutherian mammals were significantly enriched for dysregulated genes (P=0.002 for histology, P=0.021 for cyclin E), as well as for immune and signaling pathways with essential roles in endometrial biology. Thus, our novel evolutionary-based forward genomics approach identified genes whose dysregulation during the mid-secretory phase likely contributes to the molecular etiologies of recurrent early pregnancy loss. Total RNA obtained from mid luteal phase endometrium (two replicates per biopsy) from women with recurrent early pregnancy loss (REPL). Endometrial gene expression levels were compared 1) between women with out-of-phase (n=10) and normal histological dating (n=22), 2) between women with abnormally elevated (n=9) and normal (n=23) cyclin E levels. For 5 additional women with abnormally high cyclin E levels, biopsy samples were collected before and after progesterone treatment to investigate the gene expression profiles in response to progesterone.

Project description:Transcriptome profile of receptive phase endometrium among infertile women with recurrent implantation failure (RIF) in two different endometrial preparation protocols for FET was analyzed: natural cycle (NC-FET) vs. artificial cycle (AC-FET). Fifteen endometrial biopsy samples were obtained: women with unexplained RIF (n = 5) in natural cycles for FET (NC-FET), women with unexplained RIF undergoing artificial endometrial preparation (n = 5) for FET (AC-FET), and healthy women (n = 5) with proven fertility in natural cycles (NC-FC) (Control group). All endometrial biopsies were obtained during the mid-secretory phase, at the time of ‘window of implantation’.

Project description:Endometriosis is a chronic, estrogen-dependent gynecological condition that affects approximately 10% of women of reproductive age. The most widely accepted theory of the etiology of endometriosis includes the process of retrograde menstruation, where menstrual effluent travels up the Fallopian tubes, accesses the peritoneal cavity, and in some people is able to establish endometriotic lesions. Recent reports suggest the uterus is not devoid of bacteria, as was once believed. Thus, the refluxed menstrual effluent may also carry bacteria along with it, and this bacteria has been suggested to contribute to inflammation, and establishment and growth of endometriotic lesions. Here, we sought to compare and contrast the uterine bacteria (endometrial microbiota) in women with surgically confirmed presence or absence of endometriosis using next-generation 16S rRNA gene sequencing. We obtained an average of more than 9000 sequence reads per endometrial biopsy, and found that the endometrial microbiota of women with endometriosis was more diverse (greater Shannon Diversity Index and greater proportion of ‘Other’ taxa) than that of symptomatic controls (women with pelvic pain, but with surgically confirmed absence of endometriosis; diagnosed with other benign gynecological conditions at surgery). The difference in endometrial microbiotas was supported in unsupervised cluster analyses where some clustering of endometrial microbiota by disease status (endometriosis vs. controls) was observed. The bacterial taxa enriched in the endometrial microbiota of women with endometriosis belonged to the Actinobacteria phylum, Oxalobacteraceae and Streptococcaceae families, and Tepidimonas genus, while those enriched in the symptomatic controls (without endometriosis) belonged to the Burkholderiaceae family, and Ralstonia genus. Taken together, our findings suggest the endometrial microbiota is perturbed in people with endometriosis.

Project description:The aim was to examine changes in gene expression of the endometrium exposed to long-term tamoxifen treatment in comparison to age matched controls. To achieve this, endometrial tissues were obtained from women receiving tamoxifen treatment who were undergoing a hysterectomy. Using cDNA microarrays, gene expression changes in the postmenopausal endometrium of these women was compared with that in endometrium of age matched women not receiving tamoxifen. Endometrial tissue from post-menopausal women was obtained following ethical approval from the Leicester NHS Trust. None of the women had received any hormonal treatment for two months prior to the procurement of the specimens. Tissues were taken from untreated women (n=6) or those treated for 4 to 5 years with tamoxifen (20mg/day) (n=4), aged 58-82 (65 ± 9.1, mean ± SD). Total RNA was extracted. Controls were pooled. RNA labelling, hybridisation and analysis of fluorescence was carried out as described by Turton et al (2001). Cy3/Cy5 Dye swap labelling was carried out on samples from each patient.

Project description:Background: Endometriosis affects approximately 10% of reproductive age women and 30%-50% of infertile women. Decreased endometrial receptivity is mainly responsible for infertile women with minimal/mild endometriosis. Medical therapy to improve fecundity of these women is needed. Metformin is reported to inhibit growth of ectopic lesions in endometriosis, while the effect on eutopic endometrium is unclear. The study was to identify if metformin had effect on eutopic endometrium in women with minimal/mild endometriosis and thus improve their fecundity. Materials and Methods: Paired endometrial tissues of secretory phase from participants with minimal/mild endometriosis were collected before and after two months of metformin treatment and setting metformin-free control. Protein expression profiles of endometrium were analyzed by proteomics. Results: A total of 115 proteins were detected up-regulated after metformin therapy, including Insulin-like growth factor-binding protein 7, α-antitrypsin, apolipoprotein D, Rho GDP-dissociation inhibitor 1, brain form glycogen phosphorylase, and Cathepsin B that associated with endometrial receptivity, while there had no significant changes in controls. These up-regulated markers were validated through target proteomics and further demonstrated with endometriosis mice models. Conclusions: This study revealed that metformin might ameliorate biomarkers expressions of endometrial receptivity in human and mice model. Metformin is potential to improve endometrial receptivity of endometriosis-associated infertility.
