We recently reported that Slit/Roundabout (ROBO) 1 pathway may be a constituent biomarker for recurrence of endometriosis, likely through promoting angiogenesis. In this study, we sought to determine as whether Slit2 overexpression can faci…

Pains of various kinds--dysmenorrhea, chronic pelvic pain, and dyspareunia--are the major complaints from women with endometriosis, representing the most debilitating nature of the disease. Despite extensive research, our understanding as h…

BACKGROUND: Mounting evidence shows that nuclear factor-κB (NF-κB) plays an important role in endometriosis. We therefore evaluated the therapeutic potential of andrographolide, an NF-κB inhibitor. METHODS: Primary cell cultures were perfo…

Accumulating evidence suggests that endometriosis is an epigenetic disease. This study was designed to evaluate the effect of valproic acid (VPA) and progesterone (P4) in a rat model of endometriosis on serum tumor necrosis factor-α (TNF-α)…

Adenomyosis is a tough disease to manage nonsurgically. Levo-tetrahydropalmatine (l-THP), a known analgesic, and andrographolide, a nuclear factor kappa B (NF-κB) inhibitor, are both active ingredients extracted from Chinese medicinal herbs…

Emerging evidence suggests that adenomyosis, like endometriosis, may also be an epigenetic disease. In this study, we evaluated the effect of valproic acid (VPA) in ICR mice with adenomyosis, induced by neonatal dosing with tamoxifen. For a…

OBJECTIVE(S): To determine whether nuclear factor-kappaB (NF-kappaB) is constitutively and tumor necrosis factor (TNF)-dependently activated in endometriotic cells, whether trichostatin A (TSA) can suppress NF-kappaB activation and suppress…

BACKGROUND: Heavy menstrual bleeding and dysmenorrhea are two top complaints from women with symptomatic adenomyosis, yet their etiology is poorly understood. Tissue factor (TF) has been shown to be upregulated in endometriosis and at the e…

Although pains of various kinds top the list of complaints from women with endometriosis and are the most debilitating of the disease, little is known about the mechanism/mechanisms of endometriosis-associated pains. To test the hypothesis …

OBJECTIVE: We sought to investigate the expression and localization of oxytocin receptor (OTR) and transient receptor potential vanilloid type 1 (TRPV1) in women with and without adenomyosis. STUDY DESIGN: Ectopic and homologous eutopic en…

Compared with normal endometrium, SLIT expression was statistically significantly higher in ectopic endometrium from women with adenomyosis, while roundabout 1 (ROBO1) immunoreactivity and microvessel density (MVD) level were statistically …

One primary goal of medical treatment of endometriosis is to alleviate pain and there is a pressing need for new therapeutics for endometriosis with better efficacy and side-effect profiles. Levo-tetrahydropalmatine (l-THP) has been used as…

Adenomyosis is a fairly common gynecologic disease with unknown pathogenesis. We sought to investigate as to whether the promoter of progesterone receptor isoform B (PR-B) is hypermethylated in adenomyosis and to investigate the treatment o…

p50 is a member of the NF-kappaB family known to be involved in endometriosis. To gain insight into the roles of p50 in the development of endometriosis, we cross-transplanted endometrial fragments from p50 knockout mice to wild-type mice a…

BACKGROUND: The aim of this study was to evaluate the effect of trichostatin A (TSA) in a mouse model of endometriosis on serum tumour necrosis factor alpha (TNFalpha) levels, hotplate latency, lesion size and immunoreactivity to Trpv1, Pkc…

China was the first country in the world that approved mifepristone (RU-486) for abortion. A total of 6 years after the report published in the Western world indicated that mifepristone may also be effective in treating endometriosis, the f…

Adenomyosis is a difficult disease to manage and currently there is no investigative drug for adenomyosis on the horizon. We have previously reported in a pilot study that valproic acid (VPA) appears to be effective in treating adenomyosis.…

In response to the pressing need for more efficacious and safer therapeutics for endometriosis, there have been numerous reports in the last decade of positive results from animal and in vitro studies of various compounds as potential thera…

OBJECTIVE: To investigate clinicopathological features of endometriosis-associated epithelial ovarian carcinoma. METHODS: Retrospective follow-up study, clinicopathological data from patients with ovarian epithelial carcinoma were retrieve…

Endometriosis is a common gynecologic disorder with an enigmatic etiopathogenesis. Although it has been proposed that endometriosis is a hormonal disease, an autoimmune disease, a genetic disease, and a disease caused by exposure to environ…

Compared with normal endometrium, progesterone receptor isoform B (PR-B) and IkappaBalpha immunoreactivity were statistically significantly reduced in ectopic as well as eutopic endometrium from women with adenomyosis while nuclear p65, p50…

While surgery is currently the treatment of choice for endometriosis, recurrence remains a serious problem, and its prevention is an unmet clinical need. SLIT, a secreted protein that functions through the Roundabout (ROBO) receptor as a re…

A 1993 study reporting the link between exposure to dioxin and the risk of developing endometriosis in rhesus monkeys prompted many investigators to look suspiciously at dioxin. Since 1993, many in vitro, animal and epidemiological studies …

BACKGROUND Although surgery is currently the treatment of choice for managing endometriosis, recurrence poses a formidable challenge. To delay or to eliminate the recurrence is presently an unmet medical need in the management of endometrio…

Treatment of immortalized stromal-like and epithelial-like endometriotic cells with capsaicin resulted in inhibition of proliferation in a concentration-dependent manner. In addition, endometriotic cells are more sensitive to capsaicin trea…
