PURPOSE: Endometriosis (EMS) is a chronic gynecological disorder with unclear pathogenesis. While the vaginal and gut microbiomes are known to influence EMS, few studies have analyzed both microbiomes integrally. This study aims to characte…

BACKGROUND: Endometriosis (EM) is a chronic gynecological disorder that affects 5% to 10% of women of childbearing age, often causing pelvic pain and infertility. Fibrosis is a hallmark of EM progression, yet its underlying molecular driver…

Ovarian cancer, a group of heterogeneous diseases, presents with extensive characteristics with the highest mortality among gynecological malignancies. Accurate and early diagnosis of ovarian cancer is of great significance. Here, we presen…

BACKGROUND: Preeclampsia is a pregnancy-specific clinical syndrome and can be subdivided into early-onset preeclampsia (EOPE) and late-onset preeclampsia (LOPE) according to the gestational age of delivery. Patients with preeclampsia have a…

Abstract Background: The presence of ectopic functional endometrial glands and stroma in the myometrium of the uterine cavity is considered as adenomyosis. Various inflammatory, vascular and mechanical factors are involved in the symptoms …

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common pathological type of thyroid cancer. The effect of traditional anti-tumor therapy is not ideal for the patients with recurrence, metastasis and radioiodine resistance. The abn…

Endometriosis is a common estrogen-dependent chronic inflammatory disease that leads to infertility in women of reproductive age. Perhaps infertility reflects the reduced expression of integrin αvβ3 and HOXA10 in endometriosis. Previous stu…

AIM: Study the effect of low-dose aspirin on the endometrial receptivity in endometriosis rat models. MATERIALS AND METHODS: This study is to explore the expressions of progesterone receptor and LIF among three groups of endometriosis rat …

The T cell immunoglobulin mucin molecule 3 (TIM-3), as a negative regulatory immune checkpoint, plays an important role in cellular immunity by binding to its ligand galectin-9 (Gal-9). Under abnormal conditions, this pathway can regulate t…

Expression of autophagy-related proteins, microtubule-associated protein light chain 3 (LC3) and Beclin1, and matrix metalloproteinase-2 (MMP-2) was investigated in serum and peritoneal fluid of patients with endometriosis (EM). The messeng…

The programmed death-1 (PD-1)/PD-L1 pathway plays important roles in immune responses and peripheral tolerance. Under pathological conditions, this pathway can suppress protective T cell responses and induce immune system disorders. Endomet…

The aim of this study was to investigate the role of microRNA-21 (miR-21) in the regulation of phosphatase and tensin homolog deleted from chromosome-10 (PTEN) expression and proliferation of endometrioid endometrial cancer (EEC) cells. We …

Stathmin was identified as an endometriosis-related protein by comparative proteomics in our previous study. As a microtubule-destabilizing factor, stathmin was shown to participate in the relay and integration of diverse intracellular sign…

OBJECTIVE: To examine the expression of gremlin-1 (GREM1) on the levels of messenger RNA (mRNA) and protein in eutopic endometrium and its serum level in patients with endometriosis. DESIGN: Prospective, experimental study using reverse-tr…

BACKGROUND: Annexin-1 was identified as an endometriosis-related protein by comparative proteomics in previous study. As an endogenous anti-inflammatory mediator, Annexin-1 has been shown to regulate the immune response, cell proliferation …

OBJECTIVE: To investigate the clinical features and management of ureteral endometriosis. METHODS: Patients surgically and histologically diagnosed as ureteral endometriosis from January 2001 to January 2007 in Peking Union Medical College…
