We tested the hypothesis that endometriosis can be induced in baboons more successfully by intra-pelvic injection of the pellet of menstrual endometrium when compared to its supernatant. Menstrual endometrium, separated into pellet (n = 5) …

TRIzol treatment of secretory phase endometrium allows combined proteomic and mRNA microarray analysis of the same sample in women with and without endometriosis

TRIzol treatment of secretory phase endometrium allows combined proteomic and mRNA microarray analysis of the same sample in women with and without endometriosis

BACKGROUND: At present, the only way to conclusively diagnose endometriosis is laparoscopic inspection, preferably with histological confirmation. This contributes to the delay in the diagnosis of endometriosis which is 6-11 years. So far n…

ObjectiveTo test the hypothesis that specific proteins and peptides are expressed differentially in eutopic endometrium of women with and without endometriosis and at specific stages of the disease (minimal, mild, moderate, or severe) durin…

Although endometriosis is thought to be an environmental disorder initiated by dioxin exposure, this association is controversial. This study was performed to test the hypothesis that endometriosis occurs more often in women exposed to high…

BACKGROUND: According to mRNA microarray, proteomics and other studies, biological abnormalities of eutopic endometrium (EM) are involved in the pathogenesis of endometriosis, but the relationship between mRNA and protein expression in EM i…

BACKGROUND: Lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. The aim of this study was to evaluate the combined performance of six potential plasma biomarkers in …

PROBLEM: The lack of a reliable method for early non-invasive detection of endometriosis often results in delayed diagnosis. The aim of this study was to test the hypothesis that the plasma concentration of complement factor C3a (anaphylato…

A clear picture of the dynamic relationship between the endometrium and peritoneum is emerging as both tissues may participate in the spontaneous development of endometriosis. Various adhesion molecules, pro-inflammatory cytokines and chemo…

BACKGROUND: Endometriosis occurs in 10% of women and is currently diagnosed by invasive laparoscopic testing. We tested the hypothesis that endometrial gene expression in late secretory phase endometrium differs between patients with and wi…

ObjectiveTo evaluate the mechanism of action of recombinant human tumor necrosis factor (TNF)-binding protein-1 by assessing differential expression of messenger RNA (mRNA) for cytokines, matrix metalloproteinases, and growth and adhesion f…

ObjectiveTo examine messenger (m) RNA expression of aromatase, cytokines, and adhesion factors in women with and without endometriosis.DesignPatients with endometriosis were compared with control patients.SettingUniversity Hospital Gasthuis…

Endometriosis is a gynecological disorder characterized by the growth of endometrial tissue outside the uterine cavity. Although the prevalence of endometriosis is well documented in women living in developed countries, studies on the preva…

In women of reproductive age, health economic costs are estimated to be considerably higher for endometriosis than for conditions such as Crohn's disease, migraine and hypertension, and similar to the cost of diabetes. However, more awarene…

Endometriosis is an estrogen-dependent disease and estrogen-related pathways are imbalanced in women with endometriosis. One of the key enzymes in estrogen synthesis is aromatase. Inhibiting this pathway at several points is a promising ide…

Conclusions:The size of the 2 -5 mm follicle pool is an independent and important contributor to the FA of PCOS.This result could be explained by an exaggerated physiological inhibitory effect from this pool on the terminal follicle growth,…

Endometriosis is a common, estrogen-dependent, gynaecological disease, defined as the presence of endometrial-like tissue outside the uterus. Although several medications are used for treatment of the disease, they are associated with high …

Endometriosis is more frequently diagnosed in patients with infertility than in a normal population. The goal of this paper is to give an overview of the clinical and fundamental evidence for a possible link between endometriosis and (recur…

ObjectiveTo examine differential messenger RNA (mRNA) expression of relevant cytokines, metalloproteases, growth and adhesion factors in endometrium and peritoneum from women with endometriosis when compared with women without the disease d…

ObjectiveTo test the feasibility of ProteinChip (Ciphergen Biosystems, Inc., Fremont, CA) technology as a proteomic tool in discovering and identifying proteins that are differentially expressed in endometrium, endometriotic tissue, and nor…
