Background/aimOvarian cancer is asymptomatic in its early stages, and often diagnosed at advanced stages, leading to a high recurrence rate. In recent years, exosomes have been shown to be useful for early-detection, prognosis prediction, a…

Introduction and importanceA case of Low-grade endometrial stromal sarcoma (LG-ESS) invading the great vessels is rare.Case presentationA 34-year-old female who had no past history presented to a previous hospital with abdominal distension.…

OBJECTIVE: This study elucidated the efficacy of Relugolix (REL) on the reduction of uterine volume and clinical symptoms for the treatment of adenomyosis. METHODS: We conducted a retrospective cohort study of patients who received REL (40…

BACKGROUND: MicroRNAs (miRNAs) have been implicated to play a vital role in development, differentiation, cell proliferation and apoptosis. However, which miRNAs are actually associated with endometriosis-associated ovarian cancer remains c…

Uterine leiomyoma is the most common benign tumour in women, and an appropriate animal model for leiomyoma would be useful for exploring new therapeutic strategies. Therefore, we have been challenged to develop a new simple mouse model for …

INTRODUCTION: The aim of this study was to investigate the effect of laparoscopic endometriotic cystectomy and vaporization on ovarian reserve. METHODS: We prospectively analyzed the serum level of anti-Mullerian hormone (AMH) in 62 patient…

Aim: To investigate which risk factors contribute to a lower oocyte retrieval ratio in women who are receiving controlled ovarian hyperstimulation. Methods: The authors retrospectively analyzed 329 in vitro fertilization (IVF) cycles under …

The pathogenesis of endometriosis, a chronic painful gynecological disease characterized by the presence of endometrial tissue located outside of the uterus and often adhering to the peritoneum, is known to be estrogen dependent. However, t…

Purpose: To investigate the effect of moderate to severe endometriosis on mRNA expression of growth differentiation factor-9 (GDF-9) in the granulosa cells of mature follicles. Methods: Follicular fluid (FF) was obtained from 13 patients wi…

Although endometriosis is suspected to be a cause of premature ovarian insufficiency (POI), the mechanism(s) underlying this process have not been elucidated. Recently, androgens were shown to promote oocyte maturation and to play a role in…

PURPOSE: We performed TaqMan genotyping assays of anti-Mullerian hormone (AMH) and anti-Mullerian hormone receptor type II (AMHRII) single nucleotide polymorphisms (SNPs) in order to investigate how their frequency and distribution affect i…

Study objectiveTo evaluate how endometriotic cystectomy and vaporization affect ovarian reserve after conservative surgery.DesignProspective study (Canadian Task Force classification II-1).SettingHokusetsu General Hospital.PatientsNinety-ni…

Dienogest, a synthetic progestin, has been shown to be effective against endometriosis, although it is still unclear as to how it affects the ectopic endometrial cells. Decorin has been shown to be a powerful endogenous tumor repressor acti…

PurposeExamination of the mitochondrial mRNA expression in granulosa cells from an unspecified population of infertile patients to evaluate whether recombinant follicle stimulating hormone (recFSH) is more effective in producing higher qual…

INTRODUCTION: GPR30 is a seven-transmembrane G protein-coupled estrogen receptor that regulates endometrial cellular responses to estrogen. GPR30 is often highly expressed in cancer cells from aggressive tumors. The aim of this study was to…

UnlabelledObjectivesG protein-coupled receptor 30 (GPR30) is a 7-transmembrane estrogen receptor that functions alongside traditional estrogen receptors to regulate the cellular responses to estrogen. Recent studies suggest that GPR30 expre…

OBJECTIVE: To evaluate how endometriosis affects the expression of estrogen and progesterone receptors mRNA in granulosa cells. DESIGN: Prospective study. SETTING: IVF-ET program at Osaka Medical College. PATIENT(S): Eighteen patients wi…

This study examines the role of vascular endothelial growth factor (VEGF) as a therapeutic target in clear cell carcinoma (CCC) of the ovary, which has been regarded as a chemoresistant histologic subtype. Immunohistochemical analysis using…

The expression of mitochondrial genes in granulosa cells was quantitated by real-time polymerase chain reaction. The expression ratio of mitochondrial genes in granulosa cells of patients with severe endometriosis showed no statistically si…

Survivin is a novel inhibitor of apoptosis (IAP), and the two splice variants of survivin (survivin-2B and survivin-EX3) have been identified. Gene expression levels of survivin, survivin-2B and survivin-EX3 in 56 ectopic (16 peritoneal red…

Angiogenesis is essential for the pathogenesis of endometriosis. Gene expression levels of vascular endothelial growth factor (VEGF) A and C in 10 eutopic endometrial, 23 normal peritoneal, and 62 endometriotic tissues surgically obtained f…

Various types of cell adhesion molecules and matrix metalloproteinases (MMPs) seem to play an important role in the invasion process of endometriosis; however, limited investigation has focused on their gene expression in human peritoneal e…

ObjectiveTo evaluate how endometriosis affects expression of vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) in granulosa cells.DesignProspective study.SettingIVF-ET program at Osaka Medical College.Patient(s)Seventeen pa…

Survivin is a novel inhibitor of apoptosis and is expressed during fetal development and in cancer tissues, but its expression has not been reported in normal adult tissues or benign diseases. We investigated survivin gene and protein expre…
