Epigenetic changes play significant roles in cancer development. UHRF1, an epigenetic regulator, has been shown to be overexpressed and to coordinate tumor suppressor gene (TSG) silencing in several cancers. In a previous study, we found th…

OBJECTIVE(S): This study aims to identify a critical molecule that potentially participates in endometriosis pathogenesis and characterize its correlation with dysmenorrhea and recurrence. STUDY DESIGN: We utilized a bioinformatics-based s…

Few reports have explored laparoscopic adnexal tumorectomy as a treatment for large and symptomatic ovarian leiomyomas during pregnancy. The current study presents the case of a patient with a large and symptomatic ovarian leiomyoma at 14 w…

Dual-specificity phosphatase 6 (Dusp6), Sprouty4, and similar expression to FGF (Sef) are negative modulators of FGF2/ERK1/2 signaling. The objective of the study was to evaluate the expressions of Dusp6, Sprouty4, and Sef in eutopic endome…

Phosphatase and tensin homolog (PTEN) and protein phosphatase type 2A (PP2A) are negative modulators of PI3K/AKT/survivin signaling. To evaluate immunoexpression of PTEN, PP2A and survivin in adenomyosis, ectopic lesions from 28 patients wi…

OBJECTIVE: To establish a gas chromatography/mass spectrometry (GC/MS)-based metabolomics method to compare the metabolites in the follicular fluid (FF) from patients with in vitro fertilization (IVF) and repeated IVF failure (RIF). METHOD…

OBJECTIVE: To assess the association of a single nucleotide polymorphism(SNP) in tumor suppressor gene P53 with the risk of endometriosis (EM) in Han Chinese women. METHODS: For 460 EM patients, 113 patients with endometrial carcinoma and …

STUDY QUESTION: What is the expression pattern and functionality of caveolin 1 (CAV1) in the endometrium of patients with adenomyosis? SUMMARY ANSWER: The stromal CAV1 expression is down-regulated that leads to the release of a variety of …

OBJECTIVE: To investigate the association of tumor necrosis factor-alpha (TNF-α) gene promoter region -1031T/C and its combination with interleukin-6 (IL-6) gene promoter region -634C/G single nucleotide polymorphisms (SNP) with the genetic…

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 …

Adenomyosis is a common estrogen-dependent disorder of females characterized by a downward extension of the endometrium into the uterine myometrium and neovascularization in ectopic lesions. It accounts for chronic pelvic pain, dysmenorrhea…

OBJECTIVE: To investigate the association of single nucleotide polymorphisms in cytochrome P450 17 (CYP17) and estrogen receptor alpha (ERα ) genes with the risk of endometriosis among southern Chinese women. METHODS: Two SNPs rs743572 (CY…

OBJECTIVE: To investigate the association of interleukin 6 gene (IL-6) promoter region 634C/G (rs1800796) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (Ems) in south Han Chinese women. METHODS: A ca…

Intravenous leiomyomatosis is a rare variant of leiomyoma that could result in death. Early and accurate diagnosis and appropriate treatment strategies play a dominant role in good prognosis. Eighteen cases of Intravenous leiomyomatosis , a…

OBJECTIVE: To explore the association between the arylhydrocarbon receptor gene (AhR) 1661G/A or arylhydrocarbon nuclear translocatorgene (ARNT) 567G/C polymorphism and endometriosis in southern Han Chinese women. METHODS: The polymorphism…

OBJECTIVE: To explore the stroma-epithelium interactions in endometriosis and to identify the possible signalling pathways involved in this cross-talk. DESIGN: Laboratory study via primary cultured endometrial stromal and epithelial cells.…

We describe for the first time the chemopreventive effects of S-(-)equol and R-(+)equol, diastereoisomers with contrasting affinities for estrogen receptors (ERs). S-(-)equol, a ligand for ERbeta, is an intestinally derived metabolite forme…

UNLABELLED: The objective of this study was to explore the mechanism of phosphatase and tensin homolog (PTEN) loss in endometriosis. We found that aberrant PTEN expression and mitogen-activated protein kinases (MAPK)/ERK, phosphoinositide 3…

In normal endometrium, stromal factors regulate the growth of epithelial cells. However, epithelial cells in endometriotic lesions display increased proliferation and decreased apoptosis. This work tested the hypothesis that in endometriosi…

BACKGROUND: The nonsteroidal estrogen equol occurs as diastereoisomers, S-(-)equol and R-(+)equol, both of which have significant biological actions. S-(-)equol, the naturally occurring enantiomer produced by 20-30% of adults consuming soy …

OBJECTIVE: To compare the expression of human leukocyte antigen-G (HLA-G) in endometrial samples from patients with and without adenomyosis. DESIGN: Laboratory study using human tissue. SETTING: University hospital. PATIENT(S): Thirty-fo…

The matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) may contribute to the development of adenomyosis. The aim of the present study was to investigate whether three single nucleotide polymorphisms (SNPs) i…

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…
