Abstract
Menstrual blood, containing high iron levels, can undergo retrograde transport into the abdominal cavity. Excess iron causes oxidative stress and inflammation. Iron metabolism is regulated by hepcidin, and serum hepcidin levels are increased in patients with endometriosis; however, the functions of hepcidin in normal endometrium remain unclear. We therefore aimed to examine hepcidin concentrations in patients with endometriosis and to determine if iron accumulation and hepcidin increased the production of reactive oxygen species (ROS) and inflammation in normal endometrial cells. We determined hepcidin levels in peritoneal fluid and menstrual blood from patients with and without endometriosis (25/16 and 15/15 patients, respectively). We also examined the effects of hepcidin on ferroportin expression, iron accumulation, and ROS generation in normal endometrial stromal cells (NESCs) from 20 women who underwent surgery for uterine leiomyoma, using immunohistochemistry and immunofluorescence analyses and analyzed its effect on the expression of inflammatory cytokines by real-time polymerase chain reaction. There was no significant difference in iron concentrations in menstrual blood or peritoneal fluid between women with and without endometriosis; however, women with endometriosis had significantly higher hepcidin levels in menstrual blood. Hepcidin reduced the expression of ferroportin in NESCs and promoted the accumulation of ferrous iron. Hepcidin plus ferrous iron increased the production of ROS and inflammatory cytokines compared with ferrous iron alone. These results indicate that women with endometriosis have high hepcidin levels in menstrual blood, leading to increased iron production, oxidative stress, and inflammation, which may, in turn, promote the development of endometriosis.

Abstract
Objectives The effects of laparoscopic surgical management in women with stage III/IV endometriosis remain controversial. The standard extent of resection for stage III/IV endometriosis with deep endometriosis to treat endometriosis-associated infertility is debatable. This study aimed to assess the postoperative pregnancy outcomes following a routine surgical intervention for stage III/IV endometriosis patients. Materials and Methods Patients with stage III/IV endometriosis who underwent conservative laparoscopic surgery at our hospital between January 2010 and December 2018 were retrospectively analyzed. Statistical analyses were performed to determine the correlations between endometriosis features and postoperative pregnancy outcomes. Results Of 256 patients enrolled, 94 wished to conceive. Exclusion criteria: ≥40 years, adenomyosis, partners with infertility issues. Finally, 71 women were included. The overall postoperative pregnancy rate was 76.1% (n = 54): 49 and five from non-assisted reproductive technology (ART) and ART, respectively. The postoperative pregnancy rate in patients diagnosed with infertility presurgery (40/71) was 70.0% (n = 28): 24 (non-ART) and four (ART). The endometriosis fertility index (EFI) score was higher in the pregnant than in the nonpregnant group (P = 0.03). The EFI score and surgical score of EFI were higher in the non-ART than in the ART group (P = 0.04; P = 0.02); in the infertile group, they were higher in the pregnant than in the nonpregnant group (P = 0.018; P = 0.027). Conclusion Our postoperative pregnancy rate after conservative laparoscopic surgery for patients with stage III/IV endometriosis compared favorably with previous reports. EFI was a significant predictor of postoperative pregnancy. Our surgical approach to maintain a high surgical score of EFI might help treat endometriosis-associated infertility.

Abstract
Although nutrient status plays an important role in cell metabolism, its significance in endometriosis is obscure. Herein, we investigated the effects of a low-nutrient microenvironment on endometriosis. Stromal cells (SCs) from ovarian endometrioma (OESCs) or normal endometrium without endometriosis (NESCs) were isolated and cultured. A low-nutrient microenvironment was replicated by replacing the culture medium with Hank's balanced salt solution. OESC and NESC proliferation under the low-nutrient condition was measured. The expression of exacerbating factors in endometriosis under the low-nutrient condition was examined at the mRNA and protein levels. OESCs showed higher proliferation than NESCs under the low-nutrient condition. In OESCs, the low-nutrient condition upregulated the mRNA expression of vascular endothelial growth factor (VEGF), interleukin-6 and -8, aromatase, Bcl-2, and peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) and downregulated that of BAX and induced transcription of PI.3, PII, and exon II. Western blotting revealed elevated VEGF and PGC-1α expression under the low-nutrient condition in OESCs. These changes coincided with the elevated expression of PGC-1α, which was reduced at the mRNA level upon nutrient status rescue. Endometriosis is exacerbated by altered angiogenesis, inflammation, anti-apoptosis, and local estrogen production while trying to survive under a low-nutrient microenvironment; it may be attributed to PGC-1α-mediated metabolic mechanisms.

Abstract
CONTEXT Progesterone resistance including progesterone receptor (PR) deficiency contributes to the pathophysiology of endometriosis; however, whether the PR expression levels in ovarian endometrioma (OE) correlate with the postoperative recurrence of endometriosis remains unclear. OBJECTIVE This study aimed to investigate the association between PR expression levels in OE and the recurrence of endometriosis. METHODS OE specimens were obtained from 132 patients who underwent conservative surgery for endometriosis. The PR expression levels were evaluated using the H score after immunohistochemical staining. RESULTS Of the 132 patients, 36 (27.3%) experienced recurrence and 96 (72.7%) did not. No differences were observed in the patient characteristics between the recurrence and nonrecurrence groups except for follow-up period. PR immunoreactivity in the epithelial cells (ECs) was statistically significantly lower in the recurrent group than in the nonrecurrent group (P < .01); however, this change was not observed in the stromal cells. Moreover, multivariable logistic regression analysis revealed that the H score of PR in ECs was an independent factor and was statistically significantly associated with the recurrence of endometriosis (P = .01). Furthermore, we divided the patients into PR-negative or PR-positive groups. The cumulative recurrence rate in the negative PR group was statistically significantly higher than that in the positive PR group (P = .046). CONCLUSION Low PR expression levels in OE-ECs may predict the recurrence of endometriosis. The PR status in OE-ECs is associated with the pathophysiology of the recurrence of endometriosis, and optimized postoperative management for endometriosis may be provided by referring to the PR status.

Abstract
PROBLEM Innate lymphoid cells (ILCs), a recently discovered family of innate immune cells, are responsible for the early immune response, and control both innate and adapted immune system via cytokine secretion. The role of ILCs in endometriosis has not been investigated; therefore, here, we aimed to investigate how the proportion of ILCs changes in endometriosis. METHOD OF STUDY The percentage of each ILC group in CD45+ cells was examined in the peripheral blood, peritoneal fluid, endometrium, and ovarian endometrioma obtained from women with and without endometriosis (ERB-C-1216) using flow cytometry. RESULTS Specimens were obtained from 19 women with endometriosis and 15 without endometriosis. In the endometrium, patients with endometriosis had lower proportion of ILC2 and 3 compared to control specimens (ILC2: .02±.01% vs .07±.03%; P < .05, ILC3: .31±.14% vs 1.10±.93%; P < .05). There was no significant change in the peripheral blood or the peritoneal fluid between the two groups. Additionally, ovarian endometrioma increased the proportion of ILCs (ILC1: .92±1.12%, ILC2: .08±.08%, ILC3: .70±.39%) compared to the endometrium samples of patients with endometriosis each with P < .05. Immunohistochemistry of IL-1β and IL-23, which are ILC3-inducing factors, showed no significant change in the H-score of the epithelium of the two groups, but a significant increase was found in ovarian endometrioma. CONCLUSION The proportion of ILC2 and 3 was reduced in the endometrium of patients with endometriosis, and ILCs were increased in ovarian endometrioma. Our findings may indicate a new immunological approach to understand the pathophysiology of endometriosis.

Abstract
PROBLEM Inflammation and immune responses play crucial roles in the development of endometriosis. Although interleukin-9 (IL-9) has a pro-inflammatory function in chronic inflammatory diseases, its function in endometriosis remains unknown. Here, we aimed to investigate the significance of IL-9 and IL-9-producing lymphocytes in endometriosis. METHOD OF STUDY Specimens were obtained from patients with and without endometriosis. Peritoneal fluid (PF), peripheral blood (PB), and ovarian endometrioma (OE) tissues were analyzed for the proportion of CD4+ IL-9+ lymphocytes and IL-9 concentration using flow cytometry and enzyme-linked immunosorbent assay. OE, endometrium with endometriosis (EE), and normal endometrium (NE) were analyzed for IL-9 receptor (IL-9R) expression using immunohistochemical staining. IL-9-dependent changes in Interleukin-8 (IL-8) expression in endometrial stromal cells from OE (OESCs) were evaluated using real-time PCR. RESULTS The proportion of CD4+ IL-9+ lymphocytes was higher in the PF, but not the PB, of patients with endometriosis than individuals without endometriosis (p < .05). However, IL-9 levels in the PF did not differ between those with and without endometriosis. We detected CD4+ IL-9+ lymphocytes in OE tissues and IL-9R in OE tissues and OESCs. In OESC culture, IL-9 significantly elevated IL-8 expression in a dose-dependent manner (p < .05), which was nullified by the addition of the anti-IL-9 receptor antibody. Furthermore, IL-9 additively stimulated IL-8 expression in the presence of TNF-α (p < .05). CONCLUSION Our findings show that IL-9 produced by helper T cells induces IL-8 expression, suggesting that IL-9 plays an important role in the development of endometriosis by stimulating IL-8 expression.

Abstract
Ovarian leiomyomas are very rare. We report the case of a primary ovarian leiomyoma accompanied by multiple uterine leiomyomas. A 50-year-old woman was referred to our department for heavy menstruation, and a hot spot in the uterine lumen was observed on positron emission tomography-computed tomography (PET-CT). Cervical and endometrial cytology and tumor marker tests were negative. Pelvic magnetic resonance imaging revealed an endometrial polyp and submucosal leiomyoma in the uterine lumen and a 5-cm right ovarian tumor. Laparoscopic total hysterectomy, right salpingo-oophorectomy, and left salpingectomy were performed for radical treatment. Histopathology showed that ovarian tumors contained interlacing bundles of fusiform cells encircled by normal ovarian tissue. Immunohistochemical staining showed strong and diffuse positive staining for α-smooth muscle actin. We diagnosed the tumor as a primary ovarian leiomyoma because the leiomyoma was localized in the ovary and was larger than the size of uterine leiomyomas. No metastatic lesion was found on PET-CT. There was no tumor recurrence at the 6-month follow-up.

Abstract
Laparoscopic surgery has become the gold standard treatment for endometriosis. Surgical treatment of deep endometriosis with colorectal involvement is challenging. It requires complete surgical excision of lesions despite a high risk of complications that include rectal injury, rectovaginal fistula and pelvic abscess. An intraoperative air leak test allows detection of rectal injury and reduces postoperative complications. We report a case of successful management of rectal injury during laparoscopic surgery using a rectal probe even though air leak tests were negative. A 45-year-old woman with severe endometriosis and rectal involvement underwent total laparoscopic hysterectomy combined with rectal shaving. A pinhole injury that reached the rectal muscularis layer without breaching the mucosal layer was identified using a rectal probe after negative air leak tests. The injury was repaired uneventfully. Our experience suggests that using a rectal probe could be helpful for early detection and safe repair of rectal injury during surgery.

Abstract
Objective Chronic inflammation in endometriosis is associated with increased risk of future cardiovascular disease; however, no studies have investigated the cardiovascular risk of women who have undergone hormonal therapy for endometriosis. We investigated atherosclerosis-related biomarkers in women with and without endometriosis and the effects of dienogest (DNG) and oral contraceptive (OC) therapies. Study design In this cross-sectional study, 109 women with endometriosis and 42 control women without endometriosis were enrolled. The endometriosis group was divided into the untreated (n = 34), DNG therapy (n = 33), and OC therapy (n = 42) groups. Lipid profile serum levels, inflammatory marker such as high-sensitivity C-reactive protein, oxidative stress markers such as oxidized low-density lipoprotein and diacron-reactive oxygen metabolites, and atherosclerosis indicators (cardio-ankle vascular index [CAVI] and ankle-brachial pressure index [ABI]) were measured. Results The median treatment duration was 28 months in the DNG group and 32.5 months in the OC group. Triglyceride levels were higher in the OC group than in the other three groups (P < 0.05). Regarding markers of inflammation and oxidative stress, log high-sensitivity C-reactive protein and diacron-reactive oxygen metabolites levels were higher in the untreated group than in the control group (P < 0.05), and these markers were further increased in the OC group (log high-sensitivity C-reactive protein: P < 0.05; diacron-reactive oxygen metabolites: P < 0.01), but not in the DNG group. There was no difference in the CAVI and ABI among all groups. Spearman correlation revealed a positive correlation between duration of OC therapy and CAVI (ρ = +0.49; P = 0.002), but no correlation between the duration of DNG therapy and CAVI (ρ = –0.04; P = 0.81). Conclusions Inflammation and oxidative stress markers are increased in women with untreated endometriosis. Treatment with OC, but not with DNG, further increases these levels. There was a positive association between the duration of OC administration and atherosclerosis risk for women with endometriosis. Our results suggest that DNG could be administered to endometriosis without the increased atherosclerosis risk and short-term OC administration for endometriosis is not harmful, however, atherosclerosis risk should be strictly observed.

Abstract
A tumor metastasis within another tumor is known as tumor-to-tumor metastasis (TTM). We report a 43-year-old woman who presented with hypermenorrhea and an abdominal mass. She had history of a soft tissue tumor on her left ankle at 38 years of age. Laboratory data showed slight elevation of CA125 and no other abnormal findings and magnetic resonance imaging revealed a circumscribed margin mass in the uterine fundus. We diagnosed the mass as benign leiomyoma and performed total laparoscopic hysterectomy. Postoperative pathological examination revealed TTM of synovial sarcoma within the uterine leiomyoma. A database search identified 29 cases of TTM within uterine leiomyoma. The donor tumor was mostly breast cancer (in 23 cases). To the best of our knowledge, this is the first report of a sarcoma TTM to a uterine leiomyoma. Despite the difficulty of preoperative diagnosis, TTM should be considered during the treatment approach for a patient with leiomyoma and a history of malignant tumors.

Abstract
Background The Vagi-Pipe® is a useful device for performing a total laparoscopic hysterectomy. The conventional model of the Vagi-Pipe® is unable to grasp the uterus during colpotomy for recovery of the resected uterus. However, the modified C-Type Vagi-Pipe® model has a shape that allows insertion into the vagina without removing the uterus manipulator. In this study, we will prospectively investigate the safety and efficacy of the C-Type Vagi-Pipe® in total laparoscopic hysterectomies. Materials and methods In total, 25 female subjects aged between 20 and 60 years with uterine fibroids or adenomyosis will be included. Patients with complications regarded as unsuitable for this study by the investigators will be excluded. The C-Type Vagi-Pipe® will be used rather than the conventional Vagi-Pipe® when performing a total laparoscopic hysterectomy. The primary endpoint will be safety and the secondary endpoints will be operation time, bleeding volume, and presence of complications. Ethics and dissemination The protocol was approved by the institutional review boards. Written informed consent will be obtained from all patients before registration in accordance with the Declaration of Helsinki. Results of the study will be disseminated via publications in peer-reviewed journals.

Abstract
Prolapsed uterine fibroids are pedunculated submucous fibroids that prolapse through the cervical canal. Herein, we describe the laparoscopic treatment of massive prolapsed submucous fibroids. A 47-year-old woman had experienced frequent urination and abnormal vaginal bleeding for 7 years. She presented with persistent lower abdominal pain. The uterine fundus was palpable at 3 cm above the umbilicus. Vaginal examination revealed a dark purple and easily bleeding mass in her vagina. Pelvic magnetic resonance imaging revealed a large mass prolapsing from the uterine endometrium, which occupied the cervical canal and vagina, without evidence of malignancy. Under a preoperative diagnosis of uterine fibroids with edematous degeneration, we performed laparoscopic uterine artery cutting, transvaginal removal of the fibroid by twisting, and total laparoscopic hysterectomy. Histopathological examination revealed leiomyoma with partial ischemia. Six days postoperatively, the patient was discharged without complications. This approach may be appropriate for the treatment of massive prolapsed submucous fibroids.

Abstract
Malignant hyperthermia (MH) is a life-threatening clinical syndrome of hypermetabolism involving skeletal muscle. Susceptibility to MH is inherited in an autosomal dominant manner. Its common trigger is exposure to volatile anesthetic agents or depolarizing muscle relaxants. Deep neuromuscular blockade using muscle relaxants can improve the quality of surgical conditions and prevent cardiorespiratory adverse events during laparoscopic surgery. Here we report a case of successful laparoscopic surgery under anesthetic management without neuromuscular blockade in an MH-susceptible patient. A 22-year-old woman with a family history of MH underwent laparoscopic excision of ovarian endometrioma under total intravenous anesthesia and a posterior transversus abdominis plane block. The surgery was completed uneventfully. Our experience suggests that this type of anesthetic management is useful when performing laparoscopic surgery in MH-susceptible patients.

Abstract
AIM We aimed to evaluate whether hormonal therapy immediately after postsurgical recurrence of ovarian endometrioma controls disease progression and can be an alternative therapeutic option to avoid multiple repeat surgeries. METHODS We enrolled 146 patients treated for endometrioma at the University Hospital of Kyoto Prefectural University of Medicine between 2009 and 2015. After laparoscopic cystectomy using the stripping technique, opening of cul-de-sac obliterations and complete resection of the deep infiltrating endometriosis lesions, the patients either received no treatment (n = 83), oral contraceptives (OC; n = 32) or dienogest (DNG; n = 27), depending on their medical history. Four patients were excluded because they changed their regimens during the follow-up period. All patients were followed up every 3 months. Patients who developed recurrence of endometrioma immediately received DNG, OC or gonadotropin-releasing hormone agonist. RESULTS Overall, 16 patients developed a recurrence of the endometrioma (12 in the nontreatment group, three in the OC group and one in the DNG group). The 11 patients with recurrence were treated with DNG immediately after the diagnosis of recurrent endometrioma. Among them, seven patients continued treatment with DNG (2 mg) for 24 months. After 24 months of treatment with DNG, complete resolution of recurrent endometrioma was achieved in four (57.1%) of seven patients. There was no improvement in the three patients who received OC and one patient who underwent secondary surgery. CONCLUSION DNG therapy early after recurrence of postsurgical endometrioma appears to be viable for reducing the risk of repeated surgery.

Abstract
Endometriosis is an estrogen-dependent disease, and isoflavones interact with estrogen receptors. The purposes of this study are to investigate the in vitro and in vivo effects of daidzein-rich isoflavone aglycones (DRIAs), dietary supplements, on cellular proliferation in endometriosis. Stromal cells isolated from ovarian endometrioma (OESCs) and normal endometrium (NESCs) were cultured with DRIAs, i.e., each of the DRIA components (daidzein, genistein, or glycitein), or isoflavone glycosides (IG; DRIA precursors). A mouse model of endometriosis was established by transplanting donor-mouse uterine fragments into recipient mice. Our results showed that DRIAs (0.2-20 μM) inhibited the proliferation of OESCs (P < 0.05 for 0.2 μM; P < 0.01 for 2 and 20 μM) but not of NESCs. However, daidzein, genistein, glycitein, and IG did not inhibit their proliferation. DRIA-induced suppression was reversed by inhibition of the estrogen receptor (ER)β by an antagonist, PHTPP, or by ERβ siRNA (P < 0.05), but not by MPP, an ERα antagonist. In OESCs, DRIAs led to reduced expression of IL-6, IL-8, COX-2, and aromatase, as well as reduced aromatase activity, serum glucocorticoid-regulated kinase levels, and PGE2 levels (P < 0.05). Western blot and immunofluorescence assays revealed that DRIAs inhibited TNF-α-induced IκB phosphorylation and p65 uptake into the nuclei of OESCs. In the mouse model, a DRIA-containing feed significantly decreased the number, weight, and Ki-67 proliferative activity of endometriosis-like lesions compared to in mice fed with an IG-containing feed and the control feed (P < 0.01). In conclusion, DRIAs inhibit cellular proliferation in endometriosis, thus representing a potential therapeutic option for the management of endometriosis.

Abstract
OBJECTIVE To determine the effectiveness of a 24/4-day regimen of a low-dose combination drospirenone-ethinylestradiol oral contraceptive in alleviating perimenstrual symptoms among Japanese women with endometriosis. METHODS The present prospective, non-randomized study enrolled women diagnosed with endometriosis radiographically or surgically at the Kyoto Prefectural University of Medicine hospital, Japan, between December 1, 2010 and August 31, 2013. Patients received treatment with oral drospirenone-ethinylestradiol for six treatment cycles. Dysmenorrhea, chronic pelvic pain, and dyspareunia severity were assessed using visual analog scale scores after three and six treatment cycles, and changes in perimenstrual symptoms were assessed using the menstrual distress questionnaire (MDQ) scores. RESULTS In total, 46 patients were recruited for the study. Dysmenorrhea, chronic pelvic pain, and dyspareunia were all significantly reduced after both three and six treatment cycles in comparison with baseline (P<0.001 for all comparisons). After six treatment cycles, significant reductions were observed for all menstrual MDQ measures and for the premenstrual water retention and negative-effect MDQ measures (all P<0.05). CONCLUSIONS Combination drospirenone-ethinylestradiol was effective in the treatment of dysmenorrhea, chronic pelvic pain, dyspareunia, and somatic/psychological symptoms in Japanese women with endometriosis.

Abstract
Among diseases causing acute lower abdominal pain in women, isolated fallopian tube torsion is very rare, with an annual prevalence of 1 in 1.5 million. Because it has fewer findings on imaging compared to adnexal torsion, the correct diagnosis can rarely be made before an operation. We present a case of isolated fallopian tube torsion that was suspected preoperatively by its clinical course and findings on computed tomography. A 24-year-old woman repeatedly experienced acute colicky pain in the right lower back. Transvaginal ultrasonography and magnetic resonance imaging showed a right pelvic cystic lesion with intact ovaries; these findings led us to schedule a laparoscopic examination. However, the patient presented to the emergency room with acute severe right back pain. The preoperative diagnosis considering the computed tomography findings and clinical course was consistent with fallopian tube torsion. An earlier diagnosis may have helped to preserve the fallopian tube and future fertility.

Abstract
Endometriosis is an estrogen-dependent disease. Abnormally biosynthesized estrogens in endometriotic tissues induce the growth of the lesion and worsen endometriosis-associated pelvic pain. Dienogest (DNG), a selective progesterone receptor agonist, is widely used to treat endometriosis and efficiently relieves the symptoms. However, its pharmacological action remains unknown. In this study, we elucidated the effect of DNG on enzymes involved in local estrogen metabolism in endometriosis. Surgically obtained specimens of 23 ovarian endometriomas (OE) and their homologous endometrium (EE), ten OE treated with DNG (OE w/D), and 19 normal endometria without endometriosis (NE) were analyzed. Spheroid cultures of stromal cells (SCs) were treated with DNG and progesterone. The expression of aromatase, 17β-hydroxysteroid dehydrogenase 1 (HSD17β1), HSD17β2, HSD17β7, HSD17β12, steroid sulfatase (STS), and estrogen sulfotransferase (EST) was evaluated by real-time quantitative PCR. The activity and protein level of HSD17β1 were measured with an enzyme assay using radiolabeled estrogens and immunohistochemistry respectively. OESCs showed increased expression of aromatase, HSD17β1, STS, and EST, along with decreased HSD17β2 expression, when compared with stromal cells from normal endometria without endometriosis (NESCs) (P<0.01) or stromal cells from homologous endometrium (EESCs) (P<0.01). In OESCs, DNG inhibited HSD17β1 expression and enzyme activity at 10(-7) M (P<0.01). Results of immunohistochemical analysis displayed reduced HSD17β1 staining intensity in OE w/D (P<0.05). In conclusion, DNG exerts comprehensive inhibition of abnormal estrogen production through inhibition of aromatase and HSD17β1, contributing to a therapeutic effect of DNG on endometriosis.

Abstract
OBJECTIVE To demonstrate the effects of the selective G protein-coupled estrogen receptor 1 (GPER) agonist G-1 in human ovarian endometriotic stromal cells (ESCs). DESIGN Experimental in vitro study. SETTING University hospital. PATIENT(S) A total of 33 patients with ovarian endometrioma. INTERVENTION(S) Endometriotic stromal cells from ovarian chocolate cysts were treated with the GPER agonist G-1. MAIN OUTCOME MEASURE(S) The primary outcomes were cell proliferation, measured using the WST-8 assay; cell cycle, as analyzed using flow cytometry, fluorescent immunocytochemistry, and cytotoxicity; caspase activity, as measured by fluorescent and luminescent enzyme assays; and protein expression levels, as determined by Western blot analysis. RESULT(S) G-1 suppressed ESC proliferation in a concentration-dependent manner. The inhibitory effect was not blocked when GPER signaling pathways, including the GPER itself, were inhibited. G-1 induced cell cycle arrest and accumulation in the sub-G1 phase in ESCs. Immunofluorescence analysis demonstrated that G-1 interrupted microtubule assembly at the mitotic phase. G-1 also induced caspase-3-dependent apoptosis without significant cytotoxicity. CONCLUSION(S) G-1 suppressed proliferation and induced apoptosis in ESCs, suggesting the potential use of this compound as a therapeutic drug for the treatment of endometriosis.

Abstract
CONTEXT Endometriosis is an estrogen-dependent disease, and estrogen is overproduced by abnormally elevated aromatase in endometriotic tissues. Peroxisome proliferator-activated receptor gamma, coactivator 1α (PGC-1α) is a transcriptional coactivator-modulating steroid hormone. OBJECTIVE To investigate the effect of PGC-1α on aromatase activity in endometriosis. DESIGN Specimens from ovarian endometrioma (OE), endometrium with endometriosis (EE), and normal endometrium (NE) were analyzed for PGC-1α and aromatase expression. PGC-1α-dependent changes in aromatase expression in primary cultured stromal cells (SCs) were identified using luciferase and enzymatic assays, exon I-specific RT-PCR, and real-time PCR. Environmental stimulus-induced changes in PGC-1α were also examined. RESULTS PGC-1α was more highly expressed in OE than in EE and NE (P < .01). In OE, PGC-1α was coexpressed with aromatase, and their mRNA expressions were also correlated (r = 0.56, P = .02). PGC-1α was recruited to the nuclear receptor half-site between PI.3 and PII in the aromatase promoter. PGC-1α overexpression enhanced aromatase promoter activity (P < .01), mRNA expression (P < .05), and enzymatic activity (P < .01) in SCs from OE, but not in SCs from EE or NE. The levels of PI.3, PII, and exon II mRNA increased and transcriptional enhancement was abolished by mutation of the PGC-1α-interacting site. PGC-1α expression was enhanced in SCs from OE by tumor necrosis factor (TNF)-α (P < .05) but not by hypoxia or 17β-estradiol. CONCLUSIONS PGC-1α stimulated by TNF-α regulates aromatase expression and activity to promote local estrogen biosynthesis in OE, suggesting that PGC-1α is a promising candidate for novel targeted therapies in endometriosis treatment.

Abstract
OBJECTIVE To examine whether long-term administration of dienogest following gonadotropin-releasing hormone agonist (GnRH-a) therapy would prolong the relief of pelvic pain while reducing the amount of irregular uterine bleeding. STUDY DESIGN This was a prospective, non-randomized clinical trial. Among the patients suffering from chronic pelvic pain associated with recurrent endometriosis, Group G (n=38) received GnRH-a for 4-6 months and then dienogest (1 mg/day) for 12 months. The dose of dienogest was increased to 1.5 or 2 mg/day when a patient had uncontrollable uterine bleeding {n=15 (39%)}. Group D (n=33) received only dienogest (2 mg/day) for 12 months. Pelvic pain was assessed using a visual analog scale (VAS). Uterine bleeding was semi-quantified using a pictorial blood loss assessment chart (PBAC). RESULTS In Group G, GnRH-a significantly reduced the VAS score for pelvic pain, and alleviation was maintained during the 12-month therapy with dienogest. There was no significant difference in pain reduction between Group G and Group D. The PBAC score during the first 6 months on dienogest was significantly smaller in Group G than in Group D. CONCLUSION Treatment with a GnRH-a followed by long-term dienogest therapy maintains the relief of endometriosis-associated pelvic pain achieved with GnRH-a therapy for at least 12 months. This regimen reduces the amount of irregular uterine bleeding that often occurs during the early phase of dienogest therapy.

Abstract
BACKGROUND To investigate whether polymorphisms of CYP17 and CYP19 genes are associated with the risk of endometriosis, we analysed the frequency and distribution of a single nucleotide polymorphism at the 5' untranslated region of the CYP17 gene, and a tetranucleotide (TTTA) tandem repeat polymorphism and a 3 bp insertion (I)/deletion (D) polymorphism in intron 4 of the CYP19 gene. METHODS We studied 140 patients with endometriosis, 67 with adenomyosis and/or leiomyomas and 177 healthy control women. RESULTS The distribution of the genotypes of CYP17 and alleles of the TTTA repeat polymorphism of CYP19 were not significantly different between the groups. In contrast, an increased frequency of the D/D genotype was observed in the endometriosis group as compared with the control group (D/D genotype versus I/I plus I/D genotypes; corrected P = 0.024). This was more evident in the endometriosis subgroups with chocolate cysts (corrected P = 0.043) and at severe clinical stages (corrected P = 0.035). CONCLUSIONS The results suggest that the 3 bp I/D polymorphism of the CYP19 gene may be weakly associated with the susceptibility of endometriosis in a Japanese population.

Abstract
PROBLEM Interleukin-10 (IL-10) is an important immunomodulatory cytokine. The aim of this study was to investigate whether polymorphisms of the IL-10 gene promoter polymorphisms may be responsible in part for genetic susceptibility to endometriosis. METHODS OF STUDY Polymorphisms at position -1082 and -592 in the IL-10 promoter region were determined in 196 patients with endometriosis and 160 fertile healthy women by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). RESULTS There were no statistically significant differences in the genotype and allele frequencies of IL-10 promoter polymorphism between the endometriosis and control groups. However, when subgrouped according to clinical features, the frequencies of the -592*CC genotype and -592*C allele were significantly increased in patients with autoantibodies to carbonic anhydrase II (anti-CA II ab) compared with controls. CONCLUSION IL-10 promoter polymorphisms were associated with the production of anti-CA II ab in patients with endometriosis, suggesting a role in the genetic susceptibility for endometriosis.

Abstract
An immunohistochemical study was made of a case of serous cystadenocarcinoma that had been shown to have arisen from ovarian endometriosis. Aromatase cytochrome P450 (P450arom), an enzyme responsible for estrogen biosynthesis, was localized in the epithelial linings of the endometriosis and faintly in the transitional part, whereas it was not expressed in the carcinoma tissue. In contrast, estrogen receptors, progesterone receptors, and apoptosis-associated proteins, Fas, Fas ligand, and Bax were expressed in both endometriosis and carcinoma tissues of the tumor, whereas Bcl-2 was not expressed in either tissue of the tumor. It was suggested that the undifferentiated shift of the histologic grade might result in the loss of P450arom and that the malignant transformation was not caused by an altered balance of apoptosis-associated proteins. Accumulation of these studies may lead to a better understanding of the nature of malignant transformation of ovarian endometriosis.

Abstract
Leptin is secreted by adipocytes and regulates appetite through interaction with hypothalamic leptin receptors (OB-R). Leptin is involved in the stimulation of reproductive functions, and local expression of leptin and OB-R in the ovary, oocyte, embryo, and placenta might play a role in early development. The mRNA and protein of the long form leptin receptor (OB-R(L)) but not of leptin are expressed in the human endometrium and the abundance of OB-R mRNA expression varies during the menstrual cycle with a peak in the early secretory phase. We examined the steroidal regulation of OB-R(L) mRNA expression. Northern blot analyses showed that in organ-cultured proliferative endometrial specimens, oestradiol (10(-9) and 10(-8) mol/l) had no acute effect on the OB-R(L) mRNA expression, whereas oestradiol plus progesterone (10(-8), 10(-7) and 10(-6) mol/l) or medroxyprogesterone acetate (10(-8) and 10(-7) mol/l) suppressed the expression by approximately 50%. This progestin-induced suppression was blocked by a concomitant addition of mifepristone. Additionally, incubation of endometrial specimens in the presence of leptin resulted in the phosphorylation of its intracellular target, STAT3 (signal transducer and activator of transcription 3). These results indicate that, in the human endometrium, progestins act via the progesterone receptors to suppress functional OB-R(L) mRNA expression, and may thereby alter the sensitivity of the endometrium to leptin.

Endometriosis, adenomyosis and leiomyomata develop in women of reproductive age and regress after menopause or ovariectomy, suggesting that they grow in an oestrogen-dependent fashion. We investigated whether polymorphism in the oestrogen receptor-alpha (ERalpha) gene is related to oestrogen-dependent benign uterine disease. A total of 203 women with regular menstrual cycles underwent laparotomy or laparoscopy and were diagnosed histologically with endometriosis, adenomyosis and/or leiomyomata. Patients with cervical carcinoma in situ, tubal occlusion or adhesion but no other gynaecological disease were considered to be disease-free. A total of 179 women undergoing annual health examination were grouped as reference population. The distribution of PVUII genotypes (PP, Pp, and pp) of the ERalpha gene was different between each pair of the four groups of endometriosis, adenomyosis/leiomyomata, disease-free, and reference population (P = 0.022-0.0005), except between the former two groups. The PP genotype was less frequent in the groups of endometriosis (P = 0.0002) and adenomyosis/leiomyomata (P = 0.002) as compared to that in the disease-free group. In the endometriosis group, there was no difference in the distribution of PVUII genotypes due to complicating diseases (adenomyosis and/or leiomyomata) or severity of the clinical stages. These results suggest that the PVUII polymorphism of the ERalpha gene is associated with the risk for endometriosis, adenomyosis, and leiomyomata.

Abstract
In the human endometrium, inactivation of 17beta-estradiol to estrone is catalyzed by 17beta-hydroxysteroid dehydrogenase type 2 (17betaHSD2). Previous studies have shown that the 17betaHSD2 activity in the endometrium is elevated during the secretory phase, as compared with the level during the proliferative phase, and that the elevation is in response to progesterone via the progesterone receptors. Recently, it has been demonstrated that aromatase cytochrome P450, the enzyme responsible for estrogen biosynthesis, is not present in the endometrium obtained from normal menstruating women with cervical cancer in situ showing no other gynecological disease (defined as "disease free"), but present in the endometrium obtained from patients with endometriosis, adenomyosis, and/or leiomyomas (defined as "diseased"). However, the previous 17betaHSD studies have been performed without distinguishing between disease-free and diseased endometria. We, therefore, analyzed 17betaHSD2 distinguishing between disease-free and diseased endometria. During the proliferative phase, the abundance of messenger RNA (mRNA) and activity of 17betaHSD2 were comparable in both disease-free and diseased endometrium. However, during the secretory phase, while the abundance of mRNA and activity of 17betaHSD2 increased 4- to 6-fold in diseased endometrium, the 17betaHSD2 remained unchanged in the disease-free endometrium. Kinetic studies showed that the Km was identical among the four groups of endometria, suggesting that the elevation of 17betaHSD2 simply resulted from increased mRNA transcription. Organ culture of proliferative endometria in the presence of progestins resulted in the stimulation of 17betaHSD2 in diseased endometria via the progesterone receptors, whereas disease-free endometrium was not stimulated by progestins. These results suggest that the previous paradigm that 17betaHSD2 activity in the endometrium is elevated during the secretory phase is confined to diseased endometrium but not to disease-free endometrium and that the estrogen metabolism is altered in the endometria of the patients with estrogen-dependent benign diseases.

Abstract
Endometriotic implants, like other estrogen-dependent tumors, contain both estrogen receptors and aromatase cytochrome P450 (P450arom), suggesting that at a local level, endometriotic implants produce estrogens, which may be involved in tissue growth through interaction with the estrogen receptors. P450arom is also expressed in the eutopic endometria of patients with endometriosis, adenomyosis, and/or leiomyomas, whereas neither P450arom protein nor mRNA is expressed in the eutopic endometria of normal menstruating women with cervical carcinoma in situ yet showing no other gynecological disease (disease-free). Examination of P450arom expression in endometrial biopsy specimens enables the physician to discriminate between the presence and absence of endometriosis, and may be used as an initial screening at outpatient infertility clinics.

Abstract
Leptin is secreted by adipocytes and regulates appetite through interaction with hypothalamic leptin receptors (OB-R). Accumulated evidence shows that leptin is involved in the stimulation of reproductive functions and that local expression of leptin and OB-R in the ovary, oocyte, embryo, and placenta plays a role in early development. To investigate the role of leptin in implantation, we examined the expression of OB-R and leptin in the human endometrium. Northern and Western blot analyses and RT-PCR showed that the long form of OB-R (OB-R(L)) messenger ribonucleic acid (mRNA) and protein were expressed. In contrast, leptin mRNA or protein was not detected. All of the splice variants of OB-R (OB-R(T)) and OB-R(L) transcripts were expressed in 90% and 84% of the cases, respectively. OB-R mRNA expression peaked in the early secretory phase. Decidual tissue of early gestation also expressed OB-R(T) and OB-R(L). Their incidence and abundance were comparable among endometria with benign uterine diseases and disease-free endometria and were not related to a body mass index within the normal range. The present results indicate that OB-R, but not leptin, is expressed in the human endometrium.

Abstract
OBJECTIVE To evaluate the clinical usefulness of examining endometrial biopsy specimens for aromatase cytochrome P-450 as a diagnostic test for endometriosis. DESIGN Retrospective, case-controlled study. SETTING Department of Obstetrics and Gynecology, Kyoto Prefectural University of Medicine, Kyoto, Japan. PATIENT(S) One hundred five women of reproductive age with normal menstrual cycles underwent endometrial biopsy laparotomy or laparoscopy, and examination of their tissue revealed endometriosis, adenomyosis, and/or leiomyomas. Patients who had cervical carcinoma in situ but no other gynecologic disease were considered to be disease-free. INTERVENTION(S) Endometrial biopsy specimens were collected. MAIN OUTCOME MEASURE(S) The expression of aromatase cytochrome P-450 was examined by reverse transcription-polymerase chain reaction and immunohistochemical analysis. The distribution and intensity of the immunostaining was assessed using a semiquantitative index designed H-score. RESULT(S) Immunostaining for aromatase cytochrome P-450 was detected in biopsy specimens obtained from patients with endometriosis, adenomyosis, and/or leiomyomas but not in specimens obtained from disease-free patients (H-score <20), with a sensitivity and specificity of 91% and 100%, respectively. CONCLUSION(S) The expression of aromatase cytochrome P-450 in biopsy specimens of eutopic endometrium distinguishes between disease-free women and women with endometriosis, adenomyosis, and/or leiomyomas. This technique can be used at outpatient infertility clinics as an initial screening procedure to rule out the presence of estrogen-dependent disease.

Abstract
Leptin, the obese (ob) gene product, is secreted by adipocytes and regulates appetite through interaction with hypothalamic leptin receptors. Leptin may also have a stimulatory effect on reproductive function. Furthermore, leptin receptor mRNA is expressed in the ovary, suggesting a direct effect on its function. The present study examines the direct role of leptin on the oestrogen-producing activity in human luteinized granulosa cells. The cells were obtained from in-vitro fertilization pre-ovulatory follicles, precultured for 24 h in the presence of 5% charcoal-treated serum, and incubated for 48-96 h in a serum-free medium containing recombinant human leptin, follicle stimulating hormone (FSH), and/or insulin-like growth factor-I (IGF-I). A single addition of leptin (0. 5-10 ng/ml) stimulated aromatase activity with the incubation time of up to 96 h. The addition of leptin (1 ng/ml) further augmented the stimulation by a single addition of FSH (100 ng/ml) or IGF-I (100 ng/ml), or a combination of both. A single addition of leptin (1 ng/ml) or a combination of leptin (1 ng/ml), FSH (100 ng/ml), and IGF-I (100 ng/ml) gave rise to an increase in each parameter of oestrogen-producing activity measured, i.e. P450arom mRNA level, P450arom protein level, aromatase specific activity, and the oestradiol concentration in the culture supernatant. However, the production of progesterone did not change. These results indicate that leptin stimulates oestrogen production by increasing P450arom mRNA and P450arom protein expression and, consequently, aromatase activity by its direct action on the human luteinized granulosa cells.
