Cyclooxegenase-2 expression was evaluated by immunohistochemistry in endometrioma tissue samples taken from 109 patients, of whom 53 had recurrence by 30 months after surgery and 56 did not. Cyclooxegenase-2 overexpression, along with previ…

Although it is generally accepted that endometriosis is responsible for dysmenorrhea, as well as other symptoms such as infertility, the precise relationship between the severity of dysmenorrhea and various characteristics of disease, such …

BACKGROUND: Endometriosis is a benign, common gynecological disorder affecting mostly women of reproductive age. It is associated with dysmenorrhea, pelvic pain, and subfertility. The current non-surgical medical treatment is not satisfacto…

OBJECTIVE: Following our observation that histone deacetylase inhibitors (HDACIs) trichostatin A (TSA) and valproic acid (VPA) can suppress proliferation of endometrial stromal cells, we sought to determine whether TSA and VPA do so by indu…

OBJECTIVE: This study was undertaken to evaluate the immunoreactivity of progesterone receptor isoform B and nuclear factor kappa-B p65 subunit in ovarian endometrioma tissue samples harvested at the time of surgery and their relationship w…

OBJECTIVE: To identify possible sources of heterogeneities in the estimation of the proportion of bilateral cases and of left-sided cases of endometriotic lesions. DESIGN: We included 20 studies that reported estimated proportions, and exa…

AIM: To investigate patterns of and factors that may influence age at the first surgery (AATFS) for ovarian endometrioma. METHODS: Five hundred and ninety-two consecutive patients with ovarian endometriomas who underwent surgery at the Sha…

OBJECTIVE: To examine whether trichostatin A (TSA), a histone deacetylase inhibitor (HDACI), can induce up-regulation of peroxisome proliferator-activating receptor gamma (PPAR gamma) and to see whether LG100268, a retinoid X receptor (RXR)…

OBJECTIVE: To identify factors associated with the risk of developing dysmenorrhea or the severity of dysmenorrhea in women with surgically confirmed ovarian endometriomas. STUDY DESIGN: 710 patients with surgically diagnosed ovarian endom…

The knockdown of PR-B by siRNA resulted in a significant increase in proliferation in an immortalized endometrial stromal cell line. This suggests that PR-B knockdown might be responsible, at least in part, for increased proliferation and r…

Endometriosis is a poorly understood gynaecologic disorder that is associated with infertility. In this study, we examined the expression of HOXA10 in the eutopic endometrium of baboons with induced endometriosis. A decrease in HOXA10 mRNA …

Following on the heels of the discovery that endometriosis is an epigenetic disease, we conducted a pilot study on the off-label use of valproic acid to treat adenomyosis. We found that by the end of the 3-month treatment, all three recruit…

BACKGROUND: Decades of research suggest that endometriosis is a complex disorder, with varying severity, onset and progression. Many genes have been associated with endometriosis through a number of studies and now microarray analyses have …

OBJECTIVE: To identify risk factors for and the patterns of recurrence of endometrioma and of dysmenorrhea in women with ovarian endometrioma. METHODS: We evaluated 710 consecutive patients operated on for ovarian endometriomas who were fo…

The promoter of P receptor isoform B (PR-B) has recently been shown to be hypermethylated in endometriotic tissues, but one question remains as what causes the aberrant methylation. We show that sustained stimulation of an epithelial-like e…

OBJECTIVE: Over-production of cyclooxygenase-2 (COX-2) plays an important role in the positive feedback loop that leads to proliferation and inflammation in endometriosis. Following our observation that histone deacetylase inhibitors (HDACI…

PURPOSE OF REVIEW: There is a growing interest in the search for genetic variants that predispose women to endometriosis, yet little headway has been made in the identification of such variants, and published studies are often conflicting. …

The objective of this study is to determine whether trichostatin A (TSA) can suppress the invasiveness of 2 endometriotic cell lines known to be invasive and E-cadherin negative. The membrane invasion culture system was used to assess cell …

In 1999, a phase II clinical trial on the use of fulvestrant to treat endometriosis was launched; yet after 7 years there is still no report on its outcome. In 2005, another trial on the use of raloxifene to treat endometriosis was terminat…

OBJECTIVE: Since endometriosis is a persistent disease with substantial gene dysregulation, there must be cellular memory of some sort that constitutes a unique cell identity for endometriotic cells. Epigenetic regulation, especially throug…

BACKGROUND/AIMS: Ectopic and eutopic endometria of women with endometriosis have been shown to contain genomic alterations. In this study, we sought to identify genomic alterations in both ectopic and eutopic endometria of 5 women with endo…

BACKGROUND: All current major medications in treating endometriosis are effective in treating pain, most likely through suppression of proliferation of the implants, yet their effectiveness is relatively short term and they all have many un…

Endometriosis, defined as the ectopic presence of endometrial glandular and stromal cells outside the uterine cavity, is a common benign gynecological disorder with an enigmatic pathogenesis. Many genes and gene products have been reported …

The physiological effects of progesterone (P) are mediated by two isoforms of progesterone receptors (PRs): PR-A and PR-B. Progestins have long been used in the treatment of endometriosis but unfortunately the relief of pain is relatively s…

OBJECTIVE: To identify possible sources of heterogeneity in estimates of the prevalence of endometriosis in previously fertile women and in women with infertility. DESIGN: A pooled analysis of previously published studies reporting prevale…
