OBJECTIVE: To investigate the role of DNA methylation in the regulation of matrix metalloproteinase 9 (MMP-9) gene expression in endometriosis. METHODS: MMP-9 gene methylation status in eutopic and ectopic endometria were analyzed by methy…

During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of …

OBJECTIVE: To investigate the effects of oxytocin on high-intensity focused ultrasound (HIFU) ablation for the treatment of adenomyosis. MATERIALS AND METHODS: Eighty-six patients with adenomyosis from three hospitals were randomly assigne…

UNLABELLED: Steroidogenic factor 1 (SF-1), a transcriptional factor essential for estrogen biosynthesis, is undetectable in endometrial stromal cells and aberrantly expressed in endometriotic stromal cells. OBJECTIVE: We tried to gain furt…

Activating mutations of Kras oncogene and deletions of Pten tumor suppressor gene play important roles in cancers of the female genital tract. We developed here new preclinical models for gynecologic cancers, using conditional (Cre-loxP) mi…

Malignant germ cell tumors of the ovary are very rare and account for about 2-5% of all ovarian tumors of germ origin. Most patients are adolescent and young women, approximately two-thirds of them are under 20 years of age, occasionally in…

OBJECTIVE: To study pregnancy outcome and recurrence in patients with different type of endometriosis related infertility treated by conservative surgery. METHODS: From January 2005 to December 2010, 79 patients with endometriosis related …

OBJECTIVE: To evaluate the effects of ultrasound-guided high-intensity focused ultrasound (HIFU) on adenomyosis. METHODS: In a retrospective analysis, data were reviewed from 202 patients with adenomyosis who underwent ultrasound-guided HI…

Despite being a histologically dynamic organ, mechanisms coordinating uterine regeneration during the menstrual/estrous cycle and following parturition are poorly understood. In the current study, we hypothesized that endometrial epithelial…

STUDY QUESTION: Is Nometastatic gene 23-H1 (NME1, also known as nm23-H1) involved in regulating the biological behavior of endometrial stromal cells (ESCs), and does it participate in the pathogenesis of endometriosis? SUMMARY ANSWER: NME1…

Programmed cell death 6 (PDCD6), a calcium binding protein of the penta EF-hand protein family, and its receptors are involved in regulation of apoptosis pathways. To evaluate the relationship between genetic polymorphisms of PDCD6 gene and…

OBJECTIVE: Transforming growth factor-1 (TGF-β1), vascular endothelial growth factor (VEGF), and interleukin-10 (IL-10) may be critical cytokines in the microenvironment of a tumor, playing roles in immune suppression. This study was conduc…

PURPOSE: To test the feasibility of MRI-guided high intensity focused ultrasound ablation for adenomyosis. MATERIALS AND METHODS: Patients with symptomatic adenomyosis were treated with MRI-guided high intensity focused ultrasound (MRIgHIF…

BACKGROUND: Ovarian cysts are a common cause for gynecological surgery. However, some cysts are a direct result of endocrine disorders and do not require surgery. This report describes an unusual case in which persistent ovarian cysts are a…

The discovery of microRNAs (miRNAs) represents one of the most significant advances in biological and medical sciences in the last decade. Hundreds of miRNAs have been identified in plants, viruses, animals and human beings, and these tiny,…

Formaldehyde, the recently classified carcinogen and ubiquitous environmental contaminant, has long been suspected of causing adverse reproductive and developmental effects, but previous reviews were inconclusive, due in part, to limitation…

The contribution of the stromal microenvironment to the progression of endometrial cancer has not been well explored. We have conditionally expressed a mutant allele of adenomatous polyposis coli (APC(cKO)) in murine uterine stroma cells to…

Numerous proinflammatory cytokines, such as TNFalpha and IL-6, which are nuclear factor kappaB (NF-kappaB) target genes, have been shown to promote proliferation in endometriotic cells, and several other genes involved in promoting growth a…

The objective of this study was to prepare a novel mifepristone-loaded PCL/Pluronic F68 implant to achieve long-term treatment of endometriosis. PCL/Pluronic F68 compound (90/10, w/w) with viscosity average molecular weight of 65,000 was su…

INTRODUCTION: An excessive inflammatory response is thought to account for the pathogenesis of sepsis and multiple organ dysfunction syndrome (MODS) after severe trauma. The interleukin-10 (IL-10) is a potent anti-inflammatory cytokine. The…

Leiomyomas and other mesenchymally derived tumors are the most common neoplasms of the female reproductive tract. Presently, very little is known about the etiology and progression of these tumors, which are the primary indication for hyste…

OBJECTIVE: To investigate the effects of testosterone and metformin on glucose metabolism in endometrium. DESIGN: In vitro experiment. SETTING: Reproductive and Genetic Center, Obstetrics and Gynecology, The First Hospital of Peking Unive…

BACKGROUND: The pathogenesis of endometriosis remains poorly defined. The aberrant angiogenesis that occurs in eutopic endometrium may play a role in the lesion formation and survival. The difference in gene expression profile between human…

Many chemokines likely contribute to the pathogenesis of endometriosis. The authors hypothesize that the broad-spectrum chemokine inhibitor NR58-3.14.3 may prevent ectopic human endometrium implantation and growth. After placing human endom…
