Defective decidualization of endometrial stromal cells (ESCs) in endometriosis (EM) patients leads to inadequate endometrial receptivity and EM-associated infertility. Hypoxia is an inevitable pathological process of EM and participates in …

OBJECTIVE: The enigmatic nature of Endometriosis (EMS) pathogenesis necessitates investigating alterations in signaling pathway activity to enhance our comprehension of the disease's characteristics. METHODS: Three published gene expressio…

Abstract Purpose To test the expression profile of transient receptor potential channels (TRPs) in adenomyosis patients and evaluate the effects of primidone on tamoxifen-induced adenomyosis mice. Methods Eutopic endometrium from adenomyosi…

Endometriosis is a common gynecological disorder that causes female infertility. Our recent research found that excessive oxidative stress in ovaries of endometriosis patients induced senescence of cumulus granulosa cells. Here, we analyzed…

Endometrial hyperplasia is caused by an excess of estrogen unopposed by progesterone. Oral progestogens are traditionally used for endometrial hyperplasia without atypia. However oral progestogen is not always successful at causing regressi…

The mechanism by which endometriosis, a common gynecological disease characterized by chronic pelvic pain and infertility, causes infertility remains elusive. Luteinized unruptured follicle syndrome, the most common type of ovulatory dysfun…

BACKGROUND: RRM2 plays an important role in different malignant tumors, but there are few studies in breast cancer. Public databases were used to analyze the expression of RRM2 in breast cancer and its prognostic value. MATERIALS AND METHO…

BACKGROUND: Increasing evidence suggests a link between vitamin D and polycystic ovary syndrome (PCOS). However, whether vitamin D is related to hyperandrogenemia in PCOS is still inconclusive. The aim of our study is to elucidate the relat…

RESEARCH QUESTION: Could METTL3 and METTL14-mediated N6-methyladenosine (m6A) modification play possible cooperative roles in pathogenesis and progression of endometriosis? DESIGN: An investigation into m6A methylation profiles and the rol…

BACKGROUND: Postmenopausal bleeding and an endometrial thickness ≥ 5 mm on sonograms of menopausal women can indicate the presence of endometrial lesions. Diagnostic hysteroscopy is a powerful method for endometrial diseases. AIM: To inves…

BACKGROUND: While the majority of COVID-19 patients fully recover from the infection and become asymptomatic, a significant proportion of COVID-19 survivors experience a broad spectrum of symptoms lasting weeks to months post-infection, a p…

Central nervous system (CNS) disorders, such as ischemic stroke, Alzheimer's disease, Parkinson's disease, spinal cord injury, glioma, and epilepsy, involve oxidative stress and neuronal apoptosis, often leading to long-term disability or d…

INTRODUCTION: Cesarean scar pregnancy affects 6% of all ectopic pregnancies in women with prior cesarean section, and there is currently no consensus on the optimal treatment. Options of surgical treatment have a risk of intraoperative bloo…

OBJECTIVE: The principal purpose of this study was to compare reproductive outcomes for stimulated cycles (STC) and hormone replacement cycles (HRC) for endometrial preparation before frozen-thawed embryo transfer (FET) in young women with …

BACKGROUND: The optimal time at which to perform a frozen-thawed embryo transfer (FET) following a failed in-vitro fertilization-embryo transfer (IVF-ET) attempt remains elusive to most reproductive experts. Physicians often delay the intro…

Objective: The aim of this study is to investigate, in ovulatory patients, whether there is a difference in reproductive outcomes following frozen-thawed embryo transfer (FET) in natural cycles (NC) compared to modified natural cycles (mNC)…

Endometriosis affects about 10-15% women for reproductive age, but it is not currently curable and the underlying etiology for this disease is still not clear. In the present study, functions and mechanisms of miR-182 and RELA in endometrio…

The increasing number of patients with infertility is recognized as an emerging problem worldwide. However, little is known about the cause of infertility. At present, it is believed that infertility may be related to genetic or abnormal im…

BACKGROUND: Ovarian clear cell carcinoma (OCCC) arises from endometriosis and represents a difficult-to-treat gynaecological malignancy, in part, because its spatial intratumour heterogeneity and temporal evolutionary trajectories have not …

OBJECTIVE: The transcription factor Specificity protein 1 (Sp1) plays important roles in many critical biological functions; however, its expression and underlying functions in endometriosis remain undefined. Bioinformatics has suggested th…

RATIONALE: Recurrent massive hemorrhagic ascites secondary to endometriosis is extremely rare in the medical literature. PATIENT CONCERNS: We report the case of a 24-year-old nulliparous woman presenting with severe abdominal distention, m…

OBJECTIVE: To measure the expression of OATP4A1 and PGE2 in adenomyosis tissues, and to explore their roles in the incidence and development of adenomyosis-induced dysmenorrhea. METHODS: OATP4A1 mRNA and protein in the Aadenomyosis tissues…

Aim: Transfer RNA-derived fragments have been reported to play a vital role in disease progression, but their role in the pathogenesis of endometriosis remains unknown. Materials & methods: Small RNA sequencing was conducted in three paired…

AIM: Circular RNAs (circRNAs) with miRNA response elements (MREs) could function as competing endogenous RNA (ceRNA) in regulating gene expression. This study was carried out to identify the expression profile and role of circRNAs in endome…

The present study aimed to detect the expression of somatostatin (SS) and SS receptor (SSTR)1-5 in tissues from patients with endometriosis (EMS). Reverse transcription-quantitative polymerase chain reaction analysis was applied to examine …
