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 re…

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 …

ObjectiveTo analyze the determinants of successful pregnancy following laparoscopic adenomyomectomy.DesignRetrospective cohort study.SettingA general hospital.Patient(s)A total of 102 women who had a desire for pregnancy underwent laparosco…

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…

ObjectiveThe objective of this study was to determine the genes that may be associated with malignant transformation of ovarian endometrioma.MethodsEndometriotic epithelial cells were isolated from tissues derived from chocolate cyst lining…

ObjectiveTo evaluate the effects of parthenolide on human endometriotic cells and murine endometriotic lesions.DesignExperimental study.SettingUniversity hospital and laboratory of animal science.Patient(s) and animal(s)Twenty women with ov…

ObjectiveThe aim of the present study was to differentiate and specify the subtypes of adenomyosis.Study designSurgically treated adenomyosis (n = 152) was subcategorized retrospectively into 4 subtypes on the basis of magnetic resonance im…

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 and…

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 …

ObjectiveTo search for the demethylated cytosine-phosphate-guanine (CpG) islands within the aromatase gene in stromal cells derived from endometriotic chocolate cysts.DesignProspective study.SettingDepartment of Obstetrics and Gynecology an…

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 …

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…

Background and objectivesShoulder 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 evacuatio…

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…

ObjectiveTo 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.DesignProspective study.SettingDepartment of…

ObjectiveTo 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.DesignA controlled clinical study and an in …

ObjectiveTo explore novel endometriosis serum biomarkers by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS).DesignFirst, we aimed to discover the potential biomarkers of endometriosis by SELDI-TO…

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…

ObjectiveTo examine the molecular basis of aromatase expression in stromal cell culture from endometriotic chocolate cysts.DesignProspective study.SettingDepartment of Obstetrics and Gynecology and Department of Biosignaling, Tottori Univer…

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…

ObjectiveTo 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 (ESC…

BACKGROUND: The survival of endometriotic cells in the ectopic site has been investigated from the aspect of susceptibility of endometriotic tissues to apoptosis. In order to investigate the nature of abnormal survival of endometriotic cell…
