Guizhi Fuling prescription (GFP), a prestigious prescription of traditional Chinese medicine (TCM) recorded in "Jingui Yaolue," was composed of five Chinese medicines, including Moutan Cortex, Paeoniae Radix Alba, Persicae Semen, Poria Coco…

Background: Endometriosis is a debilitating gynecological condition that manifests many common malignant features, including migration and invasion. Hypoxia is a hallmark of endometriosis, characterized by endometrial cell metastasis via ep…

Endometriosis (EMs) is an estrogen (E2)-dependent inflammatory disorder. Although EMs is considered a benign disease, it presents with malignant characteristics, such as migration and invasion. An increasing number of studies have shown tha…

Research questionWhat are the protein levels and localization of oestrogen receptors (including ERa, ERb and G protein-coupled oestrogen receptor [GPER]) and hypoxia-inducible factor-1alpha (HIF-1a) in normal control endometrium (COEM) and …

Endometriosis is an oestrogen-dependent disease, and epithelial-mesenchymal transition (EMT) is involved in the process of endometriosis. Whether oestrogen could induce EMT in endometriosis remains largely unknown. Here, we reported that up…

BACKGROUND: Endometriosis is a benign gynecological disorder which shares certain characteristics with malignant tumor like migration, invasion and proliferation. Glioma-associated oncogene homolog 1 (GLI1) has been implicated in some cance…

Endometriosis is a benign gynecologic disorder, and presents with malignant characteristics, such as migration and invasion. Hypoxia has been implicated in triggering epithelial-mesenchymal transition (EMT). Hypoxia is also known to induce …

Endometriosis is an estrogen-dependent benign gynecological disease that shares some common features of malignancy. Epithelial-mesenchymal transition (EMT) has been recognized as a core mechanism of endometriosis. MALAT1 is widely known as …

Endometriosis is a common gynecological disease characterized by diminished apoptosis, sustained ectopic survival of dysfunctional endometrial cells. Hypoxia has been implicated as a crucial microenvironmental factor that contributes to end…

Oestrogen has been reported to control the invasiveness of endometrial stromal cells in endometriosis. Notch signalling, a master regulator of cell invasion in tumours, is regulated by oestrogen in other diseases and hyperactivated in endom…

OBJECTIVE: To investigate whether G protein-coupled estrogen receptor (GPER, also known as GPR30 and GPER1) stabilizes hypoxia-inducible factor 1α (HIF-1α) in eutopic endometrium (EuEM) of endometriosis. DESIGN: Immunohistochemical analysi…

Endometriosis is a benign gynecological disease that shares some characteristics with malignancy like migration and invasion. It has been reported that both hypoxia-inducible factor-1α (HIF-1α) and autophagy were upregulated in ectopic endo…

STUDY HYPOTHESIS: Do estrogen and Wnt/β-catenin signaling promote vascular endothelial growth factor (VEGF) expression in endometriosis and how? STUDY FINDING: 17β-Estradiol (E2)-drives β-catenin triggered up-regulation of VEGF in effector…

STUDY QUESTION: How does hypoxia promote growth of lesions in the development of endometriosis? SUMMARY ANSWER: Hypoxia induces the epithelial-mesenchymal transition (EMT) of endometrial cells, resulting in changes in cellular characterist…

Extracellular matrix remodeling is necessary for ectopic endometrium implantation. Many studies have shown an increased expression of matrix metalloproteinase 9 (MMP9) in the ectopic endometrium of endometriosis. However, the signaling path…

Endometriosis is an estrogen-dependent disease that involves the adhesion, invasion, and angiogenesis of endometrial tissues outside of the uterine cavity. We hypothesized that a link exists between estrogen and beta-catenin (β-catenin) sig…

Endometriosis is a common benign gynecological disease defined as the presence of endometrial tissue outside the uterine cavity. The aim of this study was to identify the molecular mechanism underlying hypoxia-induced increases in invasive …

OBJECTIVE: To explore the relative factors influencing the recurrence of endometriosis. METHODS: Three hundred and fifty-six patients of endometriosis were treated with surgery and then followed up for 3 years. Seventy-five recurrent cases …

In order to investigate the mechanism of elevated vascular endothelial growth factor (VEGF) in peritoneal fluids from patients with endometriosis, macrophages were recovered from peritoneal fluids obtained at the time of diagnostic laparosc…

In order to study the angiogenesis in endometriosis, the samples of eutopic and ectopic endometria from patients with endometriosis were quantitatively analyzed by color morphometric image system (CMIS) for vascular surface area, and by exa…

Summary: In order to study the angiogenesis in endometriosis, the samples of eutopic and ectopic en-dometria from patients with endometriosis were quantitatively analyzed by color morphometric imagesystem (CMIS) for vascular surface area, a…

In order to evaluate the expression of HLA-DR antigen in glandular cells in eutopic and ectopic endometrium in patients with endometriosis, 19 infertile patients with endometriosis were analyzed immunohistochemically by labelled streptavidi…
