Malignant transformation of adenomyosis is rare, with endometrioid carcinoma being the most common histological type. Herein, we report the first extremely aggressive case of undifferentiated carcinoma arising from adenomyosis. A 59-year-ol…

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 …

Read the full review for this Faculty Opinions recommended article: Relugolix, an oral gonadotropin-releasing hormone receptor antagonist, reduces endometriosis-associated pain in a dose-response manner: a randomized, double-blind, placebo-…

It is suggested that aberrantly expressed microRNAs are involved in the pathogenesis of endometriosis. Our previous study demonstrated that expression of the microRNA hsa-miR-199a-3p is attenuated in human endometriotic cyst stromal cells (…

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…

Endometriosis is a chronic inflammatory disease which is associated with aberrant chemokine expression. We have established a three-dimensional (3D) floating collagen gel culture of human endometriotic cyst stromal cells (ECSCs) as an in vi…

OBJECTIVE: To demonstrate the feasibility of studying exosomes directly from peritoneal fluid, we isolated exosomes from endometriosis patient samples and from controls, and characterized their cargo.DESIGN: Case-control experimental study.…

BACKGROUND: A number of microRNAs are aberrantly expressed in endometriosis and are involved in its pathogenesis. Our previous study demonstrated that has-miR-100-5p expression is enhanced in human endometriotic cyst stromal cells (ECSCs). …

A number of genes involved in the pathogenesis of endometriosis are silenced by the hypermethylation of their promoter regions. We assessed the effect and mechanism of the DNA demethylating agent 5-aza-2'-deoxycytidine (5-aza-dC) (10 μM) on…

Endometriosis exhibits unique characteristics, such as fibrosis, resistance to apoptosis, and promotion of cell proliferation; however, its pathophysiology is not fully understood. Recurrence rates after treatment are high, and the progress…

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…

BACKGROUND: We previously showed that microRNA-503 (miR-503) transfection into endometriotic cyst stromal cells (ECSCs) induced cell cycle arrest at the G0/G1 phase by suppressing cyclin D1. This finding prompted us to evaluate the potentia…

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…

To evaluate the involvement of chemokines in the pathogen-esis of endometriosis, we investigated the expression of CXC chemokines in cultured ovarian endometriotic cyst stromal cells (ECSC), endometrial stromal cells with endometriosis (ESC…

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…

miR-196b targets c-myc and Bcl-2 expression, inhibits proliferation and induces apoptosis in endometriotic stromal cells
