OBJECTIVE: Mitogen-activated protein kinases (MAPKs) are involved in the proliferation and survival of endometriotic lesions. Vemurafenib (PLX4032) is a novel protein kinase inhibitor that targets BRAF, a member of the MAPK pathway. The pre…

We investigated whether serum osteopontin (OPN) levels are different according to specific phenotypes of adenomyosis and endometriosis. We conducted a prospective laboratory study in a university referral center for endometriosis between Ma…

Ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE) are the most severe forms of endometriosis, but different pathogenetic mechanisms and clinical symptoms distinguish these two forms. Corticotrophin-releasing hormone (CRH)…

We investigated whether the myometrium might be intrinsically different in women with adenomyosis. We studied whether the mitogen-activated protein kinases/extracellular signal-regulated kinases (MAPKs/ERKs) and phosphoinositide 3-kinase/ma…

BACKGROUND: Deep endometriosis invading the bowel constitutes a major challenge for the gynecologist. In addition to the greater impact on pain, the high incidence of surgical morbidity involved with bowel endometriosis poses a therapeutic …

Endometriosis is associated with local angiogenic and hypoxic mechanisms. Indeed, peritoneal fluid of women with endometriosis generates a specific microenvironment to support the growth and development of ectopic endometrial tissues. The a…

Characterizing genetic contributions to endometriosis might help to shorten the time to diagnosis, especially in the most severe forms, but represents a challenge. Previous genome-wide association studies (GWAS) made no distinction between …

STUDY OBJECTIVE: To determine whether cancer antigen-125 (CA-125) levels are increased in women with endometriosis, especially in those with endometriomas (OMAs), deep infiltrating lesions (DIE), and superficial endometriosis (SUP) compared…

INTRODUCTION: Sorafenib is a strong multikinase inhibitor targeting 2 different pathways of endometriosis pathogenesis: RAF kinase and vascular endothelial growth factor receptor (VEGFR). We investigate whether Sorafenib could control the g…

The influence of intrauterine environment on the risk of endometriosis is still controversial. Whether birth weight modifies the risk of endometriosis in adulthood remains an open question. For this purpose, we designed a case-control study…

INTRODUCTION: The pathogenesis of endometriosis, a common benign disease, remains ill-defined, although it is clear that chronic inflammation plays a crucial role through mitogen-activated protein kinase (MAPK) signaling pathways. All curre…

Endometriosis is a benign gynecologic disease, affecting women of reproductive age associated with chronic pelvic pain, dysmenorrhea, dyspareunia and infertility. Ovarian endometrioma (OMA), superficial peritoneal endometriosis (SPE), and d…

BACKGROUND: Endometriosis is a benign gynaecological disease. Abundant bulk of evidence suggests that patients with endometriosis have an immunity dysfunction that enables ectopic endometrial cells to implant and proliferate. Previous studi…

OBJECTIVES: The identification of epidemiological factors increasing the risk of endometriosis could shorten the time to diagnosis. Specific blood groups may be more common in patients with endometriosis. STUDY DESIGN: We designed a cross-…

STUDY QUESTION: Is it possible to detect associated deep infiltrating endometriosis (DIE) before surgery for patients operated on for endometriomas using a preoperative clinical symptoms questionnaire? SUMMARY ANSWER: A diagnostic score of…

INTRODUCTION: Adenomyosis, characterized by the infiltration of the myometrium by ectopic endometrial islets, is a common condition that causes dysmenorrhea, abnormal uterine bleeding and infertility. Different treatment options exist, incl…

OBJECTIVE: To assess whether a history of surgery for endometriosis could be considered as a marker for disease severity. METHODS: This cross-sectional study included 780 women with histologically proven endometriosis who underwent surgery…

STUDY QUESTION: Are the fetal membranes of women affected with endometriosis similar to those from disease-free women? SUMMARY ANSWER: Decidua of women with endometriosis is able to generate endometriotic-like lesions in contact with the f…

OBJECTIVES: To assess interleukin-1β (IL-1β) and its inhibitory soluble interleukin-1 receptor type II (IL-1sRII) levels into the serum of patients with various forms of endometriosis and normal women, and investigate the correlation with d…

The present study investigated expression and protein localization of FOXL2 messenger RNA (mRNA) in endometrium of healthy women and in patients with endometriosis during endometrial cycle. In endometriotic lesions, FOXL2 mRNA and protein w…

OBJECTIVE: Magnetic resonance imaging (MRI) and ultrasound scanning complement each other in screening for and diagnosis of endometriosis. Fusion imaging, also known as real-time virtual sonography, is a new technique that uses magnetic nav…

OBJECTIVE: The pathogenesis of endometriosis is associated with an inflammatory process. Here, we assessed if the levels of high-sensitivity C-reactive protein (hs-CRP) in serum could constitute an effective method for detecting systemic in…

STUDY QUESTION: Are protein oxidative stress markers [thiols, advanced oxidation protein products (AOPP), protein carbonyls and nitrates/nitrites] in perioperative peritoneal fluid higher in women with histologically proven endometriosis wh…

Immunological and angiogenetic factors enhance the implantation of endometrial cells in the peritoneal cavity. The aim of this work was to determine the role of the CXCL12-CXCR4 axis in the attraction and the peritoneal implantation of endo…

OBJECTIVES: The goals of the study were to describe the MR imaging features of endometriosis of the urinary tract and identify those that suggest intrinsic involvement of ureteric wall. MATERIALS AND METHODS: Thirty-five women with proven …
