ESR1 rs9340799 is associated with endometriosis-related infertility and in vitro fertilization failure.

ABSTRACT: Estrogen receptor alpha has a central role in human fertility by regulating estrogen action in all human reproductive tissues. Leukemia inhibitory factor (LIF) expression, a cytokine critical for blastocyst implantation, is mediated by estrogen signaling, so we hypothesized that ESR1 gene polymorphisms might be candidate risk markers for endometriosis-related infertility and in vitro fertilization (IVF) failure. We included 98 infertile women with endometriosis, 115 infertile women with at least one IVF failure and also 134 fertile women as controls. TaqMan SNP assays were used for genotyping LIF (rs929271), MDM2 (rs2279744), MDM4 (rs1563828), USP7 (rs1529916), and ESR1 (rs9340799 and rs2234693) polymorphisms. The SNP ESR1 rs9340799 was associated with endometriosis-related infertility (P < 0.001) and also with IVF failure (P = 0.018). After controlling for age, infertile women with ESR1 rs9340799 GG genotype presented 4-fold increased risk of endometriosis (OR 4.67, 95% CI 1.84-11.83, P = 0.001) and 3-fold increased risk of IVF failure (OR 3.33, 95% CI 1.38-8.03, P = 0.007). Our results demonstrate an association between ESR1 rs9340799 polymorphism and infertile women with endometriosis and also with women who were submitted to IVF procedures and had no blastocyst implantation.

Project description:IVF success rate remains low (usually around 30%) and many cycles are needed to achieve pregnancy, raising issues for patients and society. IVF success or failure mainly depends on quality of the oocytes retrieved and on the patient response to the ovarian stimulation. Hormonal stimulation prior to IVF influences the ovarian environment and therefore impacts oocytes and subsequent embryo quality. We believe that if more information was available to clinicians to analyze why a cycle has failed, they could adapt the next stimulation protocol accordingly and improve success rate. We believe that particular molecular signatures are associated with failure causes and that RNA analysis could be used as a diagnosis tool. The aim of this study was to compare gene expression between failed and successful IVF cycles and to determine how gene expression is affected in follicles from failed cycles. Gene expression in follicular cells obtained from IVF patients (n=32) was analyzed using microarray. Patients that did not become pregnant following the IVF cycle were compared to those that did. Quantitative RT-PCR was used to validate the microarray results and functional analysis was performed using ingenuity pathway analysis. 165 genes were differently expressed between the two groups, including many pro-inflammatory cytokines or other factors related to inflammation. For example, EGR1, IL1B, IL8, CXCL2, CCL3 and CCL4 were all up-regulated in the negative group compared to the positive group. Overexpression of several factors, some of which act upstream from VEGF, indicates increased permeability and vasodilation. Recruitment of immune cells to ovarian tissues also appears more pronounced in the negative group, and might reflect leukocytosis. Our results indicate an impaired balance between pro- and anti- inflammatory mediators in the failed IVF group and also suggest an intermediate state of OHSS that affects oocytes without leading to systemic problems. Some differentially expressed genes appear related to abnormal differentiation and increased apoptosis, which could also result from follicular aging. These findings provide potential biomarkers to identify failure causes, which should lead to improved stimulation protocols and more successful treatment of infertility.
