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 …
OBJECTIVE: To investigate the clinical features of patients in Japan with malignant transformation of ovarian endometrioma. PATIENTS: Thirty-three patients diagnosed with ovarian cancer presumably arising from endometrioma were recruited r…
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…
OBJECTIVE: To analyze the determinants of successful pregnancy following laparoscopic adenomyomectomy. DESIGN: Retrospective cohort study. SETTING: A general hospital. PATIENT(S): A total of 102 women who had a desire for pregnancy under…
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…
OBJECTIVE: The objective of this study was to determine the genes that may be associated with malignant transformation of ovarian endometrioma. METHODS: Endometriotic epithelial cells were isolated from tissues derived from chocolate cyst …
OBJECTIVE: To evaluate the effects of parthenolide on human endometriotic cells and murine endometriotic lesions. DESIGN: Experimental study. SETTING: University hospital and laboratory of animal science. PATIENT(S) AND ANIMAL(S): Twenty…
OBJECTIVE: The aim of the present study was to differentiate and specify the subtypes of adenomyosis. STUDY DESIGN: Surgically treated adenomyosis (n = 152) was subcategorized retrospectively into 4 subtypes on the basis of magnetic resona…
AIMS: We investigated the potential of gonadotropin-releasing hormone (GnRH) agonists and GnRH antagonists to inhibit cell proliferation in endometriotic and endometrial stromal cells. METHODS: Twenty patients with ovarian endometriomas an…
The nuclear factor kappaB (NF-kappaB) is a ubiquitously expressed transcription factor playing vital roles in innate immunity and other processes involving cellular survival, proliferation, and differentiation. This review highlights the im…
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…
Dienogest (DNG), a progestin of 19-nortestosterone derivative, has good oral bioavailability and is highly selective for progesterone receptors. Owing to its antiovulatory, antiproliferative activities in endometrial cells, and its inhibito…
Lipopolysaccharide-enhanced cyclooxygenase 2 (COX-2) expression and prostaglandin E2 (PGE2) production were compared in endometriotic stromal cells (ESCs) and eutopic endometrial stromal cells. Lipopolysaccharide promotes the proliferation …
BACKGROUND AND OBJECTIVES: Shoulder pain is one of the early postlaparoscopic symptoms related to CO(2) used for pneumoperitoneum and remaining in the abdomen. The present study was conducted to validate the hypothesis that complete evacuat…
Endometriosis causes pelvic pain and infertility in women of reproductive age. We explored TNFalpha-induced specific signaling pathways and gene expressions in endometriotic stromal cells (ESCs). Based on the data of the pathway specific cD…
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…
PROBLEM: We previously reported that lipopolysaccharide (LPS)-promoted endometriotic stromal cell (ESC) proliferation by inducing TNFalpha production. The aim of this study was to investigate the efficacy of TNFalpha gene silencing on LPS-t…
OBJECTIVE: To determine whether high levels of interleukin (IL)-10 can attenuate the production of tumor necrosis factor (TNF)-alpha-induced proinflammatory cytokines in endometriotic stromal cells. DESIGN: Prospective study. SETTING: Dep…
OBJECTIVE: To determine whether serum interleukin (IL)-8 concentration can be measured in patients with ovarian endometrioma and whether this measurement is a useful tool in diagnosing this disease. DESIGN: A controlled clinical study and …
OBJECTIVE: To explore novel endometriosis serum biomarkers by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS). DESIGN: First, we aimed to discover the potential biomarkers of endometriosis by SE…
Ovarian surface epithelial cells (OSEs) are considered to be the common source of endometrioma and epithelial ovarian cancer. The present study reveals that keratinocyte growth factor receptor (KGFR) messenger RNA was expressed in OSEs of e…
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…
Apoptosis plays a critical role in maintaining tissue homeostasis and represents a normal function to eliminate excess or dysfunctional cells. Accumulated evidence suggest that apoptosis helps to maintain cellular homeostasis during the men…
OBJECTIVE: To evaluate the influence of peroxisome proliferator-activated receptor-gamma (PPAR gamma) ligand (pioglitazone) on tumor necrosis factor-alpha (TNF-alpha)-induced interleukin-8 (IL-8) expression in endometriotic stromal cells (E…
