AIM: To investigate the mechanisms of histone deacetylase (HDAC) 10 inhibitors (HDAC10Is) action in endometriosis and the target molecules of HDAC10Is. METHODS: We assessed the effects of HDAC10Is, tucidinostat and TH34, on the proliferati…

Objective: The microRNA hsa-miR-132-5p is upregulated in endometriotic cyst stromal cells (ECSCs). We investigate how hsa-miR-132-5p affects the progression of endometriosis. Methods: Normal endometrial stromal cells (NESCs) that have been …

Endometrioid adenocarcinoma of the uterine cervix is rare and difficult to distinguish from endometrial adenocarcinoma, particularly in large bulky cases. Herein, we report a rare case of a large endometrioid adenocarcinoma in a 58-year-old…

Both ovarian pregnancy and endometrioma can rupture and cause life-threatening hemoperitoneum. However, little is known about their coexistence. We report the case of a 34-year-old Japanese woman with a life-threatening hemoperitoneum in th…

MicroRNAs (miRs) play an important role in the pathophysiology of endometriosis; however, the role of miR-210 in endometriosis remains unclear. This study explores the role of miR-210 and its targets, IGFBP3 and COL8A1, in ectopic lesion gr…

Deep angiomyxoma is a rare, infiltrative, hormone-dependent, benign-mesenchymal neoplasm that occurs in the deep soft tissues of the perineal regions. In total, 33% females with newly diagnosed deep angiomyxoma will typically relapse within…

Endometriosis is a benign tumor that affect 6-10% women of reproductive age. To date, it is suggested that the aberrant microRNA (miRNA) expressions play important roles in the pathogenesis of endometriosis. Reviewing the literature, we fou…

Endometriosis is a common, estrogen-dependent benign tumor that affect 3-10% women of reproductive age, and is characterized by the ectopic growth of endometrial tissue, which is found primarily in the rectovaginal septum, ovaries, and pelv…

The aim of this publication is to disseminate the clinical practice guidelines for the treatment of intestinal, bladder/ureteral, thoracic and umbilical endometriosis, already published in Japanese, to non-Japanese speakers. For developing …

Although parasitic leiomyoma could be spontaneous or iatrogenic in origin, port-site implantation of parasitic leiomyoma is an iatrogenic benign sequela of laparoscopic surgery. A 30-year-old, primigravida Japanese woman was referred after …

Background: The heritable silencing of genes, without a change in their coding sequence, is due to epigenetic mechanisms. These mechanisms involve DNA methylation, the modification of histone, and non-coding RNA. Disrupting the balance of t…

Decidualization of the endometrium and endometriosis involves the morphological and biochemical reprogramming of the estrogen-primed proliferative stromal compartment under the continuing influence of progesterone. Here, we evaluated the in…

STUDY QUESTION: Is the micro-RNA (miRNA) miR-503, downregulated in endometriotic cyst stromal cells (ECSCs) and does this affect the cell cycle, cell proliferation, angiogenesis and contractility of these cells? SUMMARY ANSWER: miR-503 expr…

Background. Although radiation exposure is of great concern to expecting patients, little information is available on the fetal radiation dose associated with prophylactic internal iliac artery balloon occlusion (IIABO). Here we estimated t…

Accumulating evidence suggests that epigenetic aberrations play definite roles in the pathogenesis of endometriosis. These include aberrations in genomic DNA methylation, microRNA expression, and histone modification. The aberrant histone m…

STUDY QUESTION: What are the roles of the microRNA miR-210-an miRNA that is up-regulated in endometriotic cyst stromal cells (ECSCs)-in the pathogenesis of endometriosis? SUMMARY ANSWER: Up-regulated miR-210 expression in ECSCs is involved…

BACKGROUND: Glycosylation is one of the most common post-translational modifications of eukaryotic proteins and is known to undergo dynamic changes in a wide range of biological processes. To date, however, the glycan expression profiles in…

CONTEXT: Accumulating evidence suggests that various epigenetic aberrations play definite roles in the pathogenesis of endometriosis. OBJECTIVE: The objective of the study was to determine the epigenetically silenced genes by histone deace…
