Background/Objectives: Endometriosis has a marked impact on fertility, although the mechanisms behind this relationship remain poorly understood, particularly in cases without significant anatomical distortions or in the context of ovarian …

BACKGROUND: Dysregulated hyaluronic acid (HA) metabolism has been shown to be implicated in several pathologies including endometriosis. 4-Methylumbelliferone (4MU) is an HA synthesis inhibitor with proven antitumour activity. In this study…

Research questionDoes resveratrol exert a potent inhibitory effect on the development of endometriosis by interfering with some pivotal processes?DesignIn-vitro cultures of primary endometriotic stromal cells, immortalized endometrial strom…

< 0.01, respectively). These results are promising and reveal that urolithins A and B, separately, have a beneficial effect on the overall endometriotic growth without affecting the body weight or estrous cycle.

Abstract STUDY QUESTION What are the effects of plant-derived antioxidant compounds urolithin A (UA) and B (UB) on the growth and pathogenetic properties of an in vitro endometriosis model? SUMMARY ANSWER Both urolithins showed inhibitory e…

Based on the inflammatory nature and hormone-dependency of endometriosis, PI3K/AKT signaling appears to influence its progression. Could the endometriosis stages be linked to differential changes in PI3K/AKT pathway regulation? The objectiv…

BACKGROUND: The development and long-term survival of endometriotic lesions is crucially dependent on an adequate vascularization. Hyaluronic acid (HA) through its receptor CD44 has been described to be involved in the process of angiogenes…

OBJECTIVES: To evaluate the effect of endometriosis on fertility and the levels of the IL-2 and IFN-γ in the peritoneal fluid in a mouse model; to evaluate the effect of pregnancy on endometriotic lesion growth, apoptosis and cell prolifera…

Endometriosis is characterized by the presence of endometrial tissue outside the uterus that causes severe pelvic pain and infertility in women of reproductive age. Although not completely understood, the pathophysiology of the disease invo…

Endometriosis is a benign gynecological disease. Cyclooxygenase-2 (COX-2) and aromatase proteins have been shown to be overexpressed in eutopic endometrium from women suffering from this disease compared to disease-free women. Furthermore, …

STUDY QUESTION: Can resveratrol and epigallocatechin-3-gallate (EGCG) inhibit the growth and survival of endometriotic-like lesions in vivo in a BALB/c model of endometriosis, and in vitro in primary cultures of human endometrial epithelial…

The main factor involved in neovascularization of ectopic endometrial tissue in endometriosis is the vascular endothelial growth factor (VEGF), which is produced both by the endometrial implant and by peritoneal macrophages. On the other ha…

ObjectiveTo evaluate the effects of celecoxib and rosiglitazone on the implantation and growth of endometriotic-like lesions in a murine model of endometriosis.DesignProspective experimental study.SettingAnimal research and laboratory facil…

The aim of this study was to evaluate the effect of vascular endothelial growth factor (VEGF) and interleukin-1beta (IL-1beta) on apoptosis induced by leuprolide acetate (LA) in endometrial epithelial cell cultures from patients with endome…

ObjectiveTo evaluate the effect of aromatase inhibitors on ectopic endometrial growth and on the release of proangiogenic and proinflammatory factors in peritoneal fluid (PF).DesignProspective experimental study.SettingAnimal research and l…

It has been postulated that gonadotropin-releasing hormone (GnRH) analogues may act directly on endometrial cells and inhibit their growth and proliferation by regulation of apoptotic and angiogenic mechanisms. Eutopic endometrial cells fro…

BACKGROUND: Our purpose was to evaluate the effect of the GnRH agonist (GnRHa), leuprolide acetate (LA), and the GnRH antagonist (GnRHant), Antide, on apoptosis and expression of apoptosis-related proteins in endometrial epithelial cell (EE…

BACKGROUND: The aim of the present study was to evaluate the effect of GnRH analogues on the in-vitro eutopic endometrial cell apoptosis and release of interleukin-1beta (IL-1beta) and vascular endothelial growth factor (VEGF). METHODS: Bio…

ObjectiveThere is growing evidence that suggests a direct action of gonadotropin-releasing hormone agonist (GnRH-a) on endometrial growth. Consequently, our purpose was to evaluate the effect of GnRH-a on in vitro eutopic endometrial cell g…

OBJECTIVE: To evaluate the effects of administering combination oral contraceptives (COCs) to patients with endometriosis on the regulation of cell growth in the eutopic endometrium. DESIGN: Prospective study. SETTING: Research institute …

The aim of this study was to elucidate whether peritoneal macrophage (pMO) alterations are a generalized feature in all stages of endometriosis and the effect of hormonal treatment on this leukocyte population. For this purpose we quantifie…

The aim of this study was to evaluate and compare the mitogenic effect of peritoneal fluid (PF) from women with mild and severe endometriosis on the endometrial stromal cell proliferation. Increasing concentrations of PF from women with and…
