Abstract Disclosure: M. Izawa: None. Y. Azuma: None. F. Tqniguchi: None. [Background]Endometriosis has been accepted as an estrogen-dependent disease, and the estrogen environment in endometriotic lesions has been proposed as a major backgr…

Abstract Disclosure: M. Izawa: None. Y. Azuma: None. F. Taniguchi: None. [Background] Endometriosis has been accepted as an estrogen-dependent, proliferative and inflammatory disease for over two decades, and the hormonal therapy targeting …

Abstract Background Endometriosis has been accepted as an estrogen-dependent disease for more than two decades. So far, estrogen modulators that targeting estrogen depletion in endometriotic lesions have been expected as the first option of…

Abstract Background: Endometriosis is an estrogen-dependent disease, and the role of estrogen is obvious because the symptoms associated with endometriosis often disappear after menopause, and GnRH agonists or progestin relieve the pelvic l…

Abstract BACKGROUND: Endometriosis is an estrogen-dependent, inflammatory disease, and the role of estrogen is obvious because the symptoms associated with endometriosis often disappear after menopause, and GnRH agonists or progestin reliev…

[Background]Endometriosis is an estrogen-dependent, inflammatory disease characterized by the presence of endometrium-like tissue primarily on the pelvic peritoneum and ovaries. There is accumulating evidence suggesting epigenetic aberratio…

PROBLEM: Genome-wide profiling of DNA methylation in endometriotic cells has shown a distinct facet of epigenetic backgrounds; however, specific DNA methylation sites responsible for aberrant gene expression in endometriosis were unknown. A…

PROBLEM: Is lipopolysaccharide (LPS) involved in the development of endometriosis? METHOD OF STUDY: BALB/c mice (n=69) were used for the murine endometriosis model. Mice with surgically induced endometriosis were injected with LPS intraper…

The molecular background of estrogen receptor (ER) expression is important to understand the pathophysiology of the high estrogen environment in endometriosis. However, the molecular details have not been fully understood. The objective of …

PROBLEM: How is the tumor necrosis factor (TNF) α-induced inhibitor of apoptosis (IAP) protein expression in endometriotic stromal cells (ESCs) involved in cell viability and signaling pathways? METHOD OF STUDY: Endometriotic stromal cells…

Endometriosis is an estrogen-dependent inflammatory disease. In endometriotic tissues, a high-estrogen environment associated with up-regulation of the aromatase gene has been well documented. There is accumulating evidence supporting a con…

Apoptosis is a distinctive form of programmed cell death resulting in the efficient elimination of cells without eliciting an inflammatory response. Endometriosis is characterized by the presence of endometrial cells with capacity to avoid …

OBJECTIVE: To search for the demethylated cytosine-phosphate-guanine (CpG) islands within the aromatase gene in stromal cells derived from endometriotic chocolate cysts. DESIGN: Prospective study. SETTING: Department of Obstetrics and Gyn…

BACKGROUND: Decreased susceptibility of endometrial tissue to apoptosis may contribute to the pathogenesis of endometriosis. We investigate the role of survivin in the pathophysiology of endometriosis through the ability of ectopic and euto…

OBJECTIVE: To examine the molecular basis of aromatase expression in stromal cell culture from endometriotic chocolate cysts. DESIGN: Prospective study. SETTING: Department of Obstetrics and Gynecology and Department of Biosignaling, Tott…
