HOXA-10 expression in the mid-secretory endometrium of infertile patients with either endometriosis, uterine fibromas or unexplained infertility†

STUDY QUESTION: Can deep infiltrating endometriotic stromal cells (DES) sense changes in extracellular matrix (ECM) stiffness and respond to them? SUMMARY ANSWER: Soft matrices inhibit cell proliferation and inactivate the fibrotic phenoty…

STUDY QUESTION: How can deep endometriotic stromal cells proliferate and persist in a fibrotic environment? SUMMARY ANSWER: The serine/threonine kinase AKT and extracellular regulated kinase (ERK) signaling pathways may co-operate to suppo…

STUDY QUESTION: Is epigallocatechin-3-gallate (EGCG) treatment effective in the treatment of fibrosis in endometriosis? SUMMARY ANSWER: EGCG appears to have antifibrotic properties in endometriosis. WHAT IS KNOWN ALREADY: Histologically, …

Endometriosis is a chronic, estrogen-dependent disease associated with infertility and pelvic pain. Endometriosis is defined by the presence of extra-uterine endometrial tissue. It affects approximately 10% of reproductive-aged women. Howev…

Study question: To compare the pregnancy rate in patients submitted to FET (Frozen Embryos Transfer) of cleavage stage embryos (Group 1), or at the blastocyst stage (Group 2). Summary answer: Our data showed that the transfer of frozen blas…

BACKGROUND: Our previous studies suggested that aberrant activation of Wnt/ß-catenin signaling might be involved in the pathophysiology of endometriosis. We hypothesized that inhibition of Wnt/ß-catenin signaling might result in inhibition …

BACKGROUND: During the development and progression of endometriotic lesions, excess fibrosis may lead to scarring, chronic pain, and altered tissue function. However, the cellular and molecular mechanisms of fibrosis in endometriosis remain…

BACKGROUND: Recent studies have indicated new physiological roles for erythropoietin (Epo) unrelated to erythropoiesis. We previously demonstrated that the Epo concentrations in peritoneal ¯uid from patients with stage I endometriosis were …

OBJECTIVE: To investigate adenosine triphosphate (ATP)-binding cassette transporter G2 (ABCG2) expression in endometriosis and in samples of endometrium from patients with and without endometriosis. DESIGN: Prospective study. SETTING: Uni…

BACKGROUND: Endometrium is derived from intermediate mesoderm via mesenchymal to epithelial transition (MET) during development of the urogenital system. By retaining some imprint of their mesenchymal origin, endometrial epithelial cells ma…

Purpose To compare pain symptoms and quality of life between epiphenomenon and endometriosis disease. Methods Between January 2004 and July 2008, 536 new cases of endometriosis confirmed by surgical biopsy were included in this observationa…

BACKGROUND: This study was designed to compare the surgical outcomes of standard and reverse laparoscopic techniques for the treatment of rectovaginal endometriosis. METHODS: A retrospective study was conducted in a teaching and research h…

Microarray technology has become a widely used tool for analyzing the expression of tens of thousands of genes simultaneously on high-density microarrays in a single experiment, together with the availability of the complete nucleotide sequ…

BACKGROUND: The objective of the present study was to expand our understanding of the role of matrix metalloproteinase-7 (MMP-7) in the pathophysiology of endometriosis. METHODS: Expression levels of MMP-7 mRNA and protein in the eutopic e…

CONTEXT: Only a few, small, human studies on E-cadherin and beta-catenin expression in normal cycling human endometrium have been reported. It remains unclear whether expression of these molecules might be altered in the endometrium of infe…

BACKGROUND: The aim of this study was to identify risk factors for the removal of normal ovarian tissue during laparoscopic cystectomy for endometriosis. METHODS: A total of 121 patients who had histologically confirmed ovarian endometrios…
