BACKGROUND: Endometriosis is often diagnosed late due to a lack of noninvasive diagnostic tools and the varied presentation of its symptoms. Identifying risk factors for endometriosis is crucial for reducing diagnosis delays, mitigating the…

OBJECTIVES: Endometriosis is an estrogen-dependent disease, and hormonal treatment is the most common treatment. Both deep infiltrating endometriosis (DIE) and ovarian endometrioma (OV) are characterized by dense surrounding fibrotic tissue…

PURPOSE: To identify risk factors that predict the persistence of noncyclical pelvic pain in patients with endometriosis despite receiving hormone therapy. METHODS: This retrospective study examined 164 patients with histopathologically co…

OBJECTIVES: A recent study has shown that myofibroblasts are primed for apoptosis when survival pathways are inhibited under fibrosis. This knowledge of apoptosis priming led to the development of methods to induce apoptosis specifically in…

This group was formed out of the conviction that endometriosis research has not progressed at a pace in proportion to disease severity and the negative impact on women's quality of life. Furthermore, advancement in our understanding of this…

Successful embryo implantation requires transient, well-controlled inflammation in decidualizing cells. In mice, Toll-like receptor (TLR) 4 signaling in endometrial epithelial cells (EECs) by stimulation with factors present in seminal flui…

L’endométriose est une maladie chronique dans laquelle des lésions ressemblant à du tissu endométrial se retrouvent hors de l’utérus, principalement dans la cavité abdomino-pelvienne. Cette maladie pourrait toucher 10 % des femmes en âge de…

STUDY QUESTION: Is interleukin-10 (IL-10) anti-fibrotic in endometriosis? SUMMARY ANSWER: IL-10 is not anti-fibrotic but pro-fibrotic in endometriosis, because IL-10 treatment of endometriotic stromal cells in vitro promotes myofibroblast p…

STUDY QUESTION: Is activation of signal transducer and activator of transcription 3 (STAT3) via interleukin-6 (IL-6) trans-signaling involved in fibrosis of endometriosis? SUMMARY ANSWER: Persistent activation of STAT3 via IL-6 trans-signal…

Endometriosis are characterized by dense fibrous tissue. Numerous studies have investigated roles of inflammation on the pathophysiology of endometriosis. However, the interplay of inflammation and fibrosis remains to be clarified. Here we …

Serum anti-Müllerian hormone (AMH) levels decrease after surgical treatment of ovarian endometrioma. This is the main reason that surgery for ovarian endometrioma endometriosis is not recommended before in vitro fertilization, unless the pa…

BACKGROUND AND PURPOSE: A high recurrence rate after medical treatment is a major clinical problem for patients with endometriosis. Here, we have evaluated the in vitro effects of combined treatment with MK2206 (an AKT inhibitor) + chloroqu…

We thank the Editor-in Chief, Professor Amrita Ahluwalia, for her fair handling of the letter from Barra et al. (2018), as well as her openness. We acknowledge the interest of Barra et al. in our work, but we are obliged to respond to their…

Endometriosis is defined as the presence of endometrial glands and stroma within extrauterine sites. Our previous study revealed an epithelial to mesenchymal transition (EMT)-like process in red peritoneal endometriosis, whereas membrane lo…

Endometriosis is a common gynecological disorder responsible for infertility and pelvic pain. A complete cure for patients with endometriosis awaits new targets and strategies. Here we show that U0126 (a MEK inhibitor) and MK2206 (an AKT in…

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…
