STUDY QUESTION: Does interleukin-32 (IL-32) play a role in the pathogenesis of endometriosis? SUMMARY ANSWER: IL-32 might be involved in the pathogenesis of endometriosis through increased viability, proliferation and invasion of endometria…

OBJECTIVE: To evaluate the efficacy and safety of dienogest treatment in patients who had received dienogest for 12 months or more to treat endometriosis. METHODS: We analyzed the clinical data of 188 women with endometriosis who had been t…

OBJECTIVE: Nuclear factor kappa-B (NF-κB) is a critical proinflammatory regulator that has been suggested to play a pivotal role in the pathogenesis and pathophysiology of endometriosis. In the present study, we aimed to evaluate whether th…

ObjectiveTo investigate the expression of p21-activated kinase 4 (Pak4) in both adenomyotic foci and the eutopic endometrium of women with adenomyosis, and whether the activities of matrix metalloproteinases (MMPs)-2 and -9 are regulated by…

CONTEXT: Although phthalates were shown to have several negative effects on reproductive function in animals, its role in the pathogenesis of endometriosis remains to be elucidated. OBJECTIVE: We aimed to investigate the in vitro and in viv…

This study was performed to investigate the expression of cathepsin B mRNA and protein in eutopic and ectopic endometrial tissues of patients with endometriosis and in normal endometrial tissues and to clarify the association between the ca…

PROBLEM: We evaluated whether the expression of NF-кB p65 subunit is increased in the eutopic endometrium and/or in the ovarian endometrioma of women with advanced stage endometriosis, and ascertained in vitro effects of proinflammatory cyt…

CONTEXT: Endometriosis is a common gynecological condition characterized by enhanced proliferation, adhesiveness, invasiveness, and survival of endometrial cells after retrograde menstruation. Originally identified as a cytoskeletal regulat…

Endometriosis is defined as the presence of functional endometrial tissue outside the uterus, causing diverse progressive symptoms such as infertility, pelvic pain, and dysmenorrhea. Although endometriosis has been described since the 1800s…

Uterus didelphys with unilateral obstructed hemivagina, and ipsilateral renal agenesis is a rare congenital anomaly due to Mllerian duct malformation. The most common clinical manifestation is dysmenorrhea, pelvic pain, vaginal or pelvic ma…

AIM: This study was performed to assess the expression levels of vascular endothelial growth factor receptor (VEGFR)-1, -2 and -3 mRNA in eutopic endometrial tissue and their effects on in vitro fertilization-embryo transfer (IVF-ET) outcom…

We evaluated whether the proinflammatory cytokines can regulate p21-activated kinase (Pak1) expression in endometrial cells as well as whether its expression is increased in endometriotic cysts. We found that interleukin-1β up-regulates Pak…

Based on the findings of several reports that have shown an increased plasma level of di-(2-ethylhexyl) phthalate (DEHP) in women with endometriosis, the present study was designed to evaluate whether in vitro treatment with DEHP can increa…

Endometriosis is a long term, disabling condition and a relatively common disease, affecting 5~15% of the adult female population.

AIM: The objective of the present study was to compare the levels of expression of epidermal growth factor (EGF), fibroblast growth factor-2 (FGF-2), and platelet-derived growth factor-A (PDGF-A) mRNA in the eutopic endometrium of women wit…

Objective: This study was designed to investigate the association between C(-634)G polymorphism in the promotor region of vascualr endothelial growth factor (VEGF) and endometriosis. Methods: The genomic DNA was extracted from 100 patients …

Objectives: The purpose of the present study is to evaluate the relationship between endometrial concentrations of estrogen receptor (ER) and progesterone receptor (PR), and sonographic endometrial findings in the preovulatory phase of mens…
