Endometriosis is a common, estrogen-dependent disease, in which endometrial tissue grows in the peritoneal cavity. These lesions often express low levels of progesterone receptors (PR), which potentially play an important role in the insuff…

The etiology and pathogenesis of endometriosis are complex with both genetic and environmental factors contributing to disease risk. Genome-wide association studies (GWAS) have identified multiple signals in the estrogen receptor 1 (ESR1) r…

OBJECTIVES: Elevated concentrations of numerous molecules have been reported in the peritoneal cavity of women with endometriosis. Until now, no factor proved sufficiently specific to endometriosis. We aimed to investigate several biomarker…

Recurrence of endometriosis after surgery constitutes a serious challenge. Whether there is an evolution of lesion subtypes with each recurrence and whether certain lesions subtypes tend to recur faster than others is not adequately address…

INTRODUCTION: Progestins are commonly prescribed first-line drugs for endometriosis. High rates of non-response and intolerance to these drugs have been previously reported. However, no study to date has investigated the characteristics and…

Endometriosis affects a large proportion of women during their reproductive years and is associated with pain and infertility, also affecting psychological wellbeing and quality of life. The pathogenesis of the disease remains unclear, alth…

STUDY QUESTION: Are genetic effects on endometrial gene expression tissue specific and/or associated with reproductive traits and diseases? SUMMARY ANSWER: Analyses of RNA-sequence data and individual genotype data from the endometrium ide…

Gene expression varies markedly across the menstrual cycle and expression levels for many genes are under genetic control. We analyzed gene expression and mapped expression quantitative trait loci (eQTLs) in endometrial tissue samples from …

Endometriosis is characterized by the growth of epithelial and stromal cells outside the uterine cavity. It has a complex etiology and affects ∼10% of reproductive age women. It is accompanied by a chronic inflammatory response with substan…

OBJECTIVE: To study obstetric outcomes and complications in women with previously excised posterior deep infiltrating endometriosis (DIE) in comparison with women without endometriosis. DESIGN: Matched case-control study. SETTING: Tertiar…

Endometriosis is the growth of endometrial tissue outside the uterus and is characterized by progesterone resistance and changes in global and progesterone target gene expression. However, the mechanism behind this and whether it is innate,…

Endometriosis is a chronic inflammatory condition characterised by the growth of endometrial epithelial and stromal cells outside the uterine cavity. In addition to Sampson's theory of retrograde menstruation, endometriosis pathogenesis is …

Endometriosis is an inflammatory disease and nuclear receptors play a crucial role in mediating the inflammatory response. In endometrial stromal cells (ESC), nuclear receptors expression can be influenced by the local environment. Progesti…

STUDY QUESTION: What are the effects of dienogest (DNG) on midkine (MK) production in women with endometriosis? SUMMARY ANSWER: DNG-mediated down-regulation of MK in vivo and in vitro. WHAT IS KNOWN ALREADY: DNG is an oral progestin that …

Endometriosis is an estrogen-dependent disease characterised by the growth of endometrial epithelial and stromal cells outside the uterus creating a chronic inflammatory environment that further contributes to disease progression. The first…

BACKGROUND: Endometriosis, the growth of endometrial tissue outside the uterine cavity, is associated with chronic pelvic pain, subfertility and an increased risk of ovarian cancer. Current treatments include the surgical removal of the les…

PROBLEM: Endometriosis is an estrogen-dependent inflammatory disease. Progestins are a first-line treatment for endometriosis via activation of pituitary progesterone receptors and suppression of systemic estrogen: a less than optimal treat…

STUDY QUESTION: Can the activity of the IκB kinase (IKKβ) complex in endometriotic cells contribute to endometriotic lesion survival? SUMMARY ANSWER: There is a constitutive activity of the IKKβ catalytic complex in peritoneal and deeply i…

BACKGROUND: The study was designed to compare the effect of in vitro FSH stimulation on the hormone production and gene expression profile of granulosa cells (GCs) isolated from single naturally matured follicles obtained from natural cycle…

Endometriosis is a gynaecological condition with an associated chronic inflammatory response. The ectopic growth of 'lesions', consisting of endometrial cells outside the uterine cavity, stimulates an inflammatory response initiating the ac…

OBJECTIVE AND DESIGN: A systematic review of all literature was done to assess the ability of the progestin dienogest (DNG) to influence the inflammatory response of endometriotic cells. MAIN OUTCOME MEASURES: In vitro and in vivo studies …

Endometriosis affects approximately 15% of reproductive aged women and is associated with chronic pelvic pain and infertility. However, the molecular mechanisms by which endometriosis impacts fertility are poorly understood. The development…

PURPOSE: To assess endometrial gene as well as protein expression of neuroendocrine and supposedly endometriosis-associated product PGP9.5 and pain symptoms in women with endometriosis and controls undergoing laparoscopy, using molecular bi…
