circRNAs (circular RNAs) play important roles in the development of endometriosis. This study aimed to explore the functions of circRNAs on endometriosis. Two ectopic, two paired eutopic, and two normal endometrial tissue samples were collected for RNA-seq to obtain circRNA profiles and construct a circRNA-miRNA-mRNA network. The validation of 9 circRNAs in 15 patients was assessed by qRT-PCR. We selected hsa_circ_0008433 as the potential biomarker, followed by examining cell proliferation, colony formation, migration, angiopoiesis, cell cycle, and apoptosis. Furthermore, the expression of apoptosis-related proteins was detected using immunofluorescence (IF) and Western blotting. Bioinformatic analysis was used to select the potential target miRNA and genes of hsa_circ_0008433. A total of 209 upregulated and 117 downregulated differentially expressed circRNAs were identified from the eutopic and ectopic endometrial tissue samples. Eight circRNA levels were significantly increased in ectopic endometrial tissue sample compared with eutopic endometrial tissue. The hsa_circ_0008433 knockdown inhibited endometrial stromal cell proliferation, migration, colony formation, and angiopoiesis; promoted cell apoptosis; and downregulated Ki67 and PCNA expression levels. Moreover, the hsa_circ_0008433 knockdown increased Bax and E-CAD expression and decreased Bcl2, CDKN1B, and CyclinD1 levels. Ten potential target miRNAs of hsa_circ_0008433 were selected, and six of them occur significantly aberrant in hsa_circ_0008433-expressing cells. Increased hsa_circ_0008433 levels regulate epithelial mesenchymal transition (EMT) in endometriosis through the circRNA-miRNA-mRNA axis.Extravillous trophoblast remodeling of the uterine spiral arteries is essential for promoting blood flow to the placenta and fetal development, but little is known about the regulation of this process. A defect in spiral artery remodeling underpins adverse conditions of human pregnancy, notably early-onset preeclampsia and fetal growth restriction, which result in maternal and fetal morbidity and mortality. Many in vitro studies have been conducted to determine the ability of growth and other factors to stimulate trophoblast cells to migrate across a synthetic membrane. Clinical studies have investigated whether the maternal levels of various factors are altered during abnormal human pregnancy. Animal models have been established to assess the ability of various factors to recapitulate the pathophysiological symptoms of preeclampsia. This review analyzes the results of the in vitro, clinical, and animal studies and describes a nonhuman primate experimental paradigm of defective uterine artery remodeling to study the regulation of vessel remodeling.The purpose of this study is to determine the factors associated with adverse maternal outcomes in pregnancies complicated by gestational diabetes mellitus (GDM) in urban Fiji. This cross-sectional study used data from existing records of singleton pregnant women with GDM attending the Colonial War Memorial Hospital (CWMH) Suva Fiji between June 2013 and May 2014. Data retrieved included demographic data, antenatal and intrapartum care data, route of delivery, treatment modality, and maternal risk factors. The prevalence of GDM is 3.0%, n = 255/8698, and the most frequent maternal complications were induction of labor (66%), C-section (32%), and preeclampsia (19%), and 25% had babies with birthweight > 4 kg. Older women (≥ 36 years) and those treated with insulin were 5.2 times and 10.7 times, respectively, more likely to have labor induction during childbirth compared with younger women and those on dietary management. Family history of diabetes was associated with 2.4× and/or 2.5× higher odds of cesarean delivery and/or develop hypertension in pregnancy, respectively. Parity > 5 children and diagnoses of GDM after the first trimester reduced the odds of cesarean delivery. The odds of developing preeclampsia in GDM was 3.4 times higher (95% confidence interval (CI) of adjusted odds ratio (aOR) 1.03, 18.78) among obese women than normal-weight women, and married women were less likely to have babies with birthweight > 4 kg. The prevalence of and adverse outcomes among women with GDM attending antenatal public health care in Suva Fiji were higher than previously reported from the hospital. Older and multiparous women with GDM, those insulin treated, and with a strong family history and high body mass index (BMI) need special attention and better monitoring by health care personnel to reduce adverse outcomes during pregnancy.Anti-phosphatidylethanolamine antibody (aPE), an anti-phospholipid autoantibody (aPL), has been proposed as a factor in recurrent pregnancy loss (RPL). However, conflicting views exist on the pathogenicity of RPL, and aPE has not yet been included in the classification criteria for antiphospholipid syndrome (APS). Here, we aimed to determine the clinical importance of examining aPE. aPE (IgG, IgM) was measured in 1705 patients with a history of RPL and re-examined after a 12-week interval in patients who tested positive. Persistent positive patients were administered low-dose aspirin during the subsequent pregnancy and clinical outcomes depending on the presence, type, and persistence of aPE were evaluated. Androgen Receptor inhibitor Among the patients positive for aPE IgG and aPE IgM in the first examination (n = 117; 6.87%, and n = 235; 13.6%, respectively), 31.5% and 37.6% were negative upon re-examination, respectively. Moreover, among the cases with known pregnancy outcome, the miscarriage rate in the cumulative positive aPE group was 32.6% (29/89), which did not differ significantly from that of the aPE negative group (27.7%; 80/209; P = 0.178). Alternatively, the miscarriage rate in the persistently positive group was 40.7% (22/54), which was significantly higher than that in the transient positive group, 20.0% (7/35) (P = 0.041). Particularly, this difference become more significant when focusing on aPE IgM, 46.9% (15/32) in the persistent, compared with 16.7% (4/24) in the transient positive group (P = 0.024). aPE IgM is suggested to serve as a pathogenic aPL together with anti-cardiolipin antibodies and lupus anticoagulants, particularly if these factors persist over an extended period of time.
