We wished to ascertain if there is an association between neutrophil extracellular traps and endometriosis (EMS). We collected the lesional tissues and normal endometrium of 30 patients suffering from endometriosis. Samples were also taken from healthy controls. Blood from the peripheral circulation was collected to isolate serum and neutrophils. A mouse model of endometriosis was also created. Expression of citrullinated histone and the myeloperoxidase level in tissue were measured by immunofluorescence staining and western blotting. The myeloperoxidase level in peripheral blood serum was measured by enzyme-linked immunosorbent assay. Staining (Trypan Blue) and flow cytometry were used to measure the apoptosis of neutrophils in peripheral blood. BALB/C mice were modeled by allotransplantation, and the experimental parameters noted above quantified. The myeloperoxidase content in the peripheral blood of patients with endometriosis was increased compared with that in healthy controls. Flow cytometry showed that the percent apoptosis of neutrophils in patients with endometriosis was lower than that in healthy controls. Expression of citrullinated histone was higher in the endometriosis group in humans and mice compared with respective controls according to immunofluorescence staining and western blotting. Our data suggest that a high concentration of neutrophil extracellular traps was observed in humans and mice suffering from endometriosis.
我们希望确定是否有中性粒细胞胞外陷阱和子宫内膜异位症(EMS)之间的联系。我们收集了30例子宫内膜异位症患者的病变组织和正常子宫内膜。样本也取自健康对照。采集外周循环血液,分离血清和中性粒细胞。建立了子宫内膜异位症小鼠模型。免疫荧光染色和免疫印迹法检测各组瓜氨酸组蛋白表达及髓过氧化物酶水平。采用酶联免疫吸附法测定外周血髓过氧化物酶水平。采用台盼蓝染色和流式细胞术检测外周血中性粒细胞凋亡情况。采用同种异体移植建立BALB/C小鼠模型,并对上述实验参数进行量化。子宫内膜异位症患者外周血髓过氧化物酶含量明显高于健康对照组。流式细胞术显示,子宫内膜异位症患者的中性粒细胞凋亡百分比低于正常对照组。免疫荧光染色和western blot结果显示,人和小鼠子宫内膜异位症组瓜氨酸组蛋白的表达均高于对照组。我们的数据表明,在患有子宫内膜异位症的人和小鼠中观察到高浓度的中性粒细胞胞外陷阱。

Backgrounds

Recent studies have found Several lncRNAs were proved differential expression in diminished ovarian reserve (DOR) patients, however, the mechanism of DOR caused by lncRNAs is still largely unclear.

Methods

High throughput sequencing was performed in ovarian GCs extracted from women with normal ovarian function and women with DOR. Bioinformation analysis was used to analyze the sequencing data and identify the differential expression of lncRNAs. Quantitative RT-PCR (qRT-PCR) was used to verify the sequencing results.
Situ fluorescence hybridization (FISH) followed by confocal microscopy and qRT-PCR were used to explore the location and expression of LncRNA-THBS4 in GCs. The significantly enriched signaling pathways of LncRNA-THBS4 were identified by KEGG.
The study used RNA interference technology to decipher LncRNA-THBS4 function by silencing LncRNA-THBS4 in GCs. Western blot and qRT-PCR were used to explore the mRNA and protein expressions of key factors of PI3Ks pathway. The pro-apoptotic protein and anti-apoptotic protein were detected by western blot. The proliferation and apoptosis of GCs were detected by MTT assay and Flow cytometry.

Results

197 lncRNAs with significant differences in expression levels were detected between control and DOR group by high throughput sequencing. The study found the expression of LncRNA-THBS4 in GCs was positively correlated with Anti-Mullerian hormone (AMH) (p = 0.0020, r = 0.4742)、antral follicle count (AFC) (p = 0.0007, r = 0.5130)、good embryo rate (p = 0.0006, r = 0.5210), negatively correlated with basal FSH level (p = 0.0007, r = -0.5152). LncRNA-THBS4 was mainly localized in the cytoplasm of GCs. LncRNA-THBS4 silencing could inhibit the PI3Ks pathway; decrease the levels of anti-apoptotic protein, inhibit the proliferation of GCs; increase the levels of apoptosis protein, enhance the apoptosis of GCs.

Conclusions

The expression level of lncRNA-THBS4 is correlated with ovarian function indicators and pregnancy outcomes in women. LncRNA-THBS4 may participate in the pathogenesis of DOR by affecting the proliferation and apoptosis of GCs via regulating PI3K/AKT/mTOR signaling pathway.
背景:近期研究发现多种lncRNAs在卵巢储备功能减退(DOR)患者中被证实存在差异表达,但lncRNAs引起DOR的机制仍不清楚。方法:对卵巢功能正常妇女和DOR妇女卵巢GCs进行高通量测序。利用生物信息分析对测序数据进行分析,鉴定lncrna的差异表达。采用定量RT-PCR (qRT-PCR)对测序结果进行验证。采用原位荧光杂交(FISH)、共聚焦显微镜和qRT-PCR技术研究LncRNA-THBS4在GCs中的定位和表达。通过KEGG鉴定了LncRNA-THBS4显著富集的信号通路。本研究利用RNA干扰技术,通过沉默GCs中的LncRNA-THBS4来破译LncRNA-THBS4的功能。采用Western blot和qRT-PCR检测pi3k通路关键因子的mRNA和蛋白表达情况。western blot检测促凋亡蛋白和抗凋亡蛋白的表达。采用MTT法和流式细胞术检测GCs的增殖和凋亡情况。结果:通过高通量测序,在对照组和DOR组中检测到197个表达水平有显著差异的lncrna。研究发现LncRNA-THBS4在gc的表达呈正相关,她们血液中的抗苗勒氏管激素(抗苗勒氏管激素)(p = 0.0020 r = 0.4742),窦的卵泡数(亚)(p = 0.0007 r = 0.5130),好的胚胎率(p = 0.0006 r = 0.5210),基础FSH水平呈负相关(p = 0.0007 r = -0.5152)。LncRNA-THBS4主要定位于GCs的细胞质中。LncRNA-THBS4沉默可抑制PI3Ks通路;降低抗凋亡蛋白水平,抑制细胞增殖;增加凋亡蛋白水平,促进细胞凋亡。结论:lncRNA-THBS4的表达水平与女性卵巢功能指标及妊娠结局相关。LncRNA-THBS4可能通过调控PI3K/AKT/mTOR信号通路影响GCs的增殖和凋亡,参与DOR的发病机制。

Background

Existing literature supports the association between atypical phospholipid antibodies - anti-phosphatidylserine/prothrombin antibodies (aPS/PT) and adverse pregnancy outcomes. This study aimed to investigate the relationship between aPS/PT and premature rupture of membranes (PROM).

Methods

A retrospective cohort study analysis was conducted on 408 pregnant women who had experienced at least one unexplained miscarriage. They were tested for aPS/PT IgM and IgG, and clinical data, test results, and follow-up pregnancy outcomes were collected.

Results

A positive correlation was observed between aPS/PT IgM or IgG and PROM in both single-factor and multi-factor regression analysis. After adjusting for potential confounders, the odds ratio (OR) values for aPS/PT IgM and aPS/PT IgG were 1.03 (95 % CI: 1–1.05, P = 0.025) and 1.03 (95 % CI: 1.01–1.06, P = 0.016) respectively. When aPS/PT was divided in three groups, djusted OR values for aPS/PT IgG of the third tertiles compared to the first tertiles (were 2.11(95 % CI: 1.11–4, P = 0.022). Subgroup analysis supported these findings. Curve fitting revealed a linear relationship between aPS/PT IgM and aPS/PT IgG with PROM.

Conclusion

This study suggests that aPS/PT IgG and aPS/PT IgM are independent risk factors for premature rupture of membranes, with aPS/PT IgG showing a higher significance compared to aPS/PT IgM.
背景:现有文献支持非典型磷脂抗体-抗磷脂酰丝氨酸/凝血酶原抗体(aPS/PT)与不良妊娠结局之间的关联。本研究旨在探讨aPS/PT与胎膜早破(PROM)的关系。方法:对408例至少发生过一次不明原因流产的孕妇进行回顾性队列研究。对她们进行aPS/PT、IgM和IgG检测,收集临床资料、检测结果和随访妊娠结局。结果:单因素和多因素回归分析均显示aPS/PT IgM或IgG与PROM呈正相关。在调整潜在混杂因素后,aPS/PT IgM和aPS/PT IgG的比值比(OR)值分别为1.03(95 % CI: 1-1.05, P = 0.025)和1.03(95 % CI: 1.01-1.06, P = 0.016)。将aPS/PT分为三组,第三分位的aPS/PT IgG与第一分位的比较,调整OR值为2.11(95 % CI: 1.11-4, P = 0.022)。亚组分析支持这些发现。曲线拟合显示aPS/PT IgM和aPS/PT IgG与PROM呈线性关系。结论:本研究提示aPS/PT IgG和aPS/PT IgM是早破膜的独立危险因素,且aPS/PT IgG比aPS/PT IgM具有更高的意义。
