STUDY QUESTION: Does the restoration of regulatory T cells (Tregs) suppress the progression of endometriosis? SUMMARY ANSWER: Adoptive transfer of Tregs suppresses the progression of endometriosis and reduces the levels of helper T (Th)-ce…

OBJECTIVE: Endometriosis is an estrogen-dependent disease wherein isoflavones interact with estrogen receptors. Daidzein-rich isoflavone aglycones (DRIAs) have been shown to inhibit cell proliferation and aromatase activity in vitro and in …

Menstrual blood, containing high iron levels, can undergo retrograde transport into the abdominal cavity. Excess iron causes oxidative stress and inflammation. Iron metabolism is regulated by hepcidin, and serum hepcidin levels are increase…

CONTEXT: Progesterone resistance including progesterone receptor (PR) deficiency contributes to the pathophysiology of endometriosis; however, whether the PR expression levels in ovarian endometrioma (OE) correlate with the postoperative re…

Chronic inflammation in endometriosis is associated with increased risk of future cardiovascular disease; however, no studies have investigated the cardiovascular risk of women who have undergone hormonal therapy for endometriosis. We inves…

PROBLEM: Inflammation and immune responses play crucial roles in the development of endometriosis. Although interleukin-9 (IL-9) has a pro-inflammatory function in chronic inflammatory diseases, its function in endometriosis remains unknown…

Laparoscopic surgery has become the gold standard treatment for endometriosis. Surgical treatment of deep endometriosis with colorectal involvement is challenging. It requires complete surgical excision of lesions despite a high risk of com…

STUDY QUESTION: Is a peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α)-mediated pathway involved in the development of endometriosis? SUMMARY ANSWER: PGC-1α plays critical roles in inflammation and cell proliferation of e…

•Malignant transformation of deep infiltrating endometriosis involving the bladder is quite rare.•We review eight relevant cases which have been reported.•This is the second case fulfilling Sampson and Scott criteria.
