Both environmental and genetic factors interact and play a critical role in the pathogenesis of endometriosis. We analyzed the plasma levels of 12 polychlorinated biphenyl (PCB) congeners with genetic polymorphisms of glutathione-S-transfer…

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…

PURPOSE: Progesterone resistance is thought to be a major factor that contributes to progression of endometriosis. However, it is not clear what causes progesterone resistance in endometriosis. This study aimed to assess whether cytokines o…

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…

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

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…

OBJECTIVE: To identify the most important factor in predicting ovarian reserve after laparoscopic ovarian cystectomy and to evaluate whether there is any difference in the postoperative decline of ovarian reserve between women with endometr…

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…

We performed the present prospective case-control study to evaluate whether the plasma concentrations of phthalate esters are elevated in women with advanced-stage endometriosis in a Korean population. Measuring plasma levels of monoethylhe…

The present study was designed to evaluate whether the expression of p21-activated kinase 1 (Pak1), which recently has been shown to be increased in the eutopic endometrium of women with endometriosis, is also increased in adenomyotic nodul…

BACKGROUND: P21-activated kinase 1 (Pak1) integrates various signaling pathways that are vital to cell survival and function. This study was performed to evaluate whether sex steroids may regulate the expression of Pak1 in endometrial cells…

PROBLEM: The intracellular antioxidant system, based on glutathione (GSH), plays a key role in endometrial detoxification reactions and has been proposed to be involved in the pathogenesis endometriosis. This study was designed to evaluate …

Angiogenin, a potent inducer of angiogenesis, is expressed in human endometrium. This study was performed to compare the expression of angiogenin mRNA level in the eutopic endometrium from women with and without endometriosis. Thirty-two wo…

Objective: 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, to compare the expression respect…
