Endometriosis is a highly prevalent gynecological disease characterized by lesions in different sites. Regulation of specific estrogen pathways may favor the formation of distinct microenvironments and the progression of endometriosis. Howe…

Given the importance of menstrual blood in the pathogenesis of endometriosis and the multifunctional roles of menstrual mesenchymal stem cells (MenSCs) in regenerative medicine, this issue has gained prominence in the scientific community. …

Research questionIs the transcriptome of cumulus cells of infertile women with advanced endometriosis (EIII/IV), with and without endometrioma, altered?DesignIn this prospective case-control study, next-generation RNA sequencing was used to…

The aim of this study was to identify the key similarities between the eutopic endometrium of women with endometriosis and chlamydia-induced endometritis taking into account tissue microenvironment heterogeneity, transcript gene profile, an…

It has been suggested that menstrual blood-derived mesenchymal stem/stromal cells (MenMSCs) are associated with the etiopathogenesis of endometriosis and considerable effort has been invested in searching for target genes and deciphering as…

RESEARCH QUESTION: Is the profile of microRNA (miRNA) altered in cumulus cells of infertile women with early (EI/II) and advanced (EIII/IV) endometriosis? DESIGN: In this prospective case-control study, a miRNA profile including 754 target…

Endometriosis is responsible for pain symptoms with great impact on the patient's quality of life. Several medication lines have been studied aiming at its definitive treatment. Among them, angiogenesis inhibitor factors may be effective gi…

Eutopic endometrium appears to be crucial for endometriosis development. Despite of the evident importance, data regarding the cellular microenvironment remain unclear. Our objective was to explore the tissue microenvironment heterogeneity,…

STUDY QUESTION: Compared to healthy women, is the profile of transcripts altered in the eutopic endometrium of infertile women with endometriosis during the implantation window (IW)? SUMMARY ANSWER: The eutopic endometrium of infertile wome…

Endometriosis is frequently related to infertility and little is known about the mechanisms underlying this association. Some studies point to an endometrial factor involved in this condition, which could compromise embryo implantation. Pro…

ObjectiveEndometriosis is characterized by the growth of endometrial tissue outside the uterine cavity. The prevalence of endometriosis among women experiencing pain, infertility, or both is as high as 35% to 50%. The most common symptoms o…

OBJECTIVE: To characterize the patterns of cell differentiation, proliferation, and tissue invasion in eutopic and ectopic endometrium of rabbits with induced endometriotic lesions via a well- known experimental model, 4 and 8 weeks after t…

Studies have demonstrated oxidative stress in peritoneal fluid (PF) from women with endometriosis and the importance of enzymatic antioxidant machinery to avoid oocyte oxidative damage. Considering that PF constantly surrounds the ovaries a…

Objective The aim of the present study was to analyze the expression of the CD63, S100A6, and GNB2L1genes, which participate in mechanisms related to the complex pathophysiology of endometriosis. Methods A case-control study was conducted w…

OBJECTIVE: Alterations in endometrial receptivity may be involved in the etiopathogenesis of endometriosis-related infertility. The literature has suggested that patients with endometriosis present progestin resistance, which could affect e…

Endometriosis is a benign, estrogen-dependent disease with symptoms such as pelvic pain and infertility, and it is characterized by the ectopic distribution of endometrial tissue. The expression of the ID2, PRELP and SMOC2 genes was compare…

A deleterious effect of endometriosis on oocyte quality has been proposed. Evidence suggests that cumulus cells could be used as indirect biomarkers of oocyte quality. The PTGS2 gene, which encodes cyclooxygenase 2 (COX-2), is deregulated i…

Several authors have investigated the malignant transformation of endometriosis, which supports the hypothesis of the pre-neoplastic state of endometriotic lesions, but there are few data about the pathways and molecular events related to t…

Aromatase plays a fundamental role in the establishment of oocyte quality, which might be compromised in infertile women with endometriosis. The expression of the CYP19A1 gene (that encodes aromatase) was compared in cumulus cells and oestr…

It is questioned whether worsening of oocyte quality and oxidative stress (OS) are involved in the pathogenesis of infertility related to endometriosis and in compromised intracytoplasmic sperm injection (ICSI) outcomes. Cumulus cells (CCs)…

Regular physical exercise seems to have protective effects against diseases that involve inflammatory processes since it induces an increase in the systemic levels of cytokines with anti-inflammatory and antioxidant properties and also acts…
