Zhang L, Liu H, Xiong W, He H, Fu T, Long X, Li X, Liang J, Ding H, Xu Y, Liu Y, Dai X. CircFOXO3 mediates hypoxia-induced autophagy of endometrial stromal cells in endometriosis. FASEB J 2024; 38:e23515. [PMID: 38470367 DOI: 10.1096/fj.202301654rr] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 02/02/2024] [Accepted: 02/12/2024] [Indexed: 03/13/2024]
Abstract
Endometriosis is a benign gynecological disease that shares some common features of malignancy. Autophagy plays vital roles in endometriosis and influences endometrial cell metastasis, and hypoxia was identified as the initiator of this pathological process through hypoxia inducible factor 1 alpha (HIF-1α). A newly discovered circular RNA FOXO3 (circFOXO3) is critical in cell autophagy, migration, and invasion of various diseases and is reported to be related to hypoxia, although its role in endometriosis remains to be elucidated up to now. In this study, a lower circFOXO3 expression in ectopic endometrium was investigated. Furthermore, we verified that circFOXO3 could regulate autophagy by downregulating the level of p53 protein to mediate the migration and invasion of human endometrial stromal cells (T HESCs). Additionally, the effects of HIF-1α on circFOXO3 and autophagy were examined in T HESCs. Notably, overexpression of HIF-1α could induce autophagy and inhibit circFOXO3 expression, whereas overexpressing of circFOXO3 under hypoxia significantly inhibited hypoxia-induced autophagy. Mechanistically, the direct combination between HIF-1α and HIF-1α-binding site on adenosine deaminase 1 acting on RNA (ADAR1) promoter increased the level of ADAR1 protein, which bind directly with circFOXO3 pre-mRNA to block the cyclization of circFOXO3. All these results support that hypoxia-mediated ADAR1 elevation inhibited the expression of circFOXO3, and then autophagy was induced upon loss of circFOXO3 via inhibition of p53 degradation, participating in the development of endometriosis.

METTL3-regulated m6A modification impairs the decidualization of endometrial stromal cells by regulating YTHDF2-mediated degradation of FOXO1 mRNA in endometriosis-related infertility. Reprod Biol Endocrinol 2023; 21:99. [PMID: 37891533 PMCID: PMC10605339 DOI: 10.1186/s12958-023-01151-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 10/13/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Endometriosis-related infertility is a common worldwide reproductive health concern. Despite ongoing research, the causes of infertility remain unclear. Evidence suggests that epigenetic regulation is crucial in reproduction. However, the role of N6-methyladenosine (m6A) modification of RNA in endometriosis-related infertility requires further investigation. METHODS We examined the expression of m6A and methyltransferase-like 3 (METTL3) in endometrial samples taken from normal fertile women in the proliferative phase (the NP group) or the mid-secretory phase (the NS group) or from women with endometriosis-related infertility at the mid-secretory phase (the ES group). We treated primary endometrial stromal cells (ESCs) with medroxyprogesterone acetate and 8-Bromo-cyclic adenosine monophosphate for in vitro decidualization and detected the expression of m6A, METTL3, and decidual markers. We analyzed the expression of m6A, METTL3, and forkhead box O1 (FOXO1) in ESCs from normal fertile women (the ND group) or women with endometriosis-related infertility (the ED group). We also assessed the expression of m6A, METTL3, and decidual markers, as well as the embryo adhesion rate, upon METTL3 overexpression or knockdown. Additionally, we investigated the role of METTL3 in embryo implantation in vivo by applying mice with endometriosis. Furthermore, we performed RNA stability assays, RNA immunoprecipitation (RIP), and methylated RIP assays to explore the mechanisms underlying the regulation of FOXO1 by METTL3-mediated m6A. RESULTS The expression of m6A and METTL3 was reduced only in the NS group; the NP and ES groups demonstrated increased m6A and METTL3 levels. m6A and METTL3 levels decreased in ESCs with prolonged decidual treatment. Compared to the ND group, m6A and METTL3 levels in the ED group increased after decidual treatment, whereas the expression of FOXO1 decreased. METTL3 overexpression suppressed the expression of decidual markers and embryo implantation in vitro; METTL3 knockdown exhibited the opposite effect. Inhibition of METTL3 promoted embryo implantation in vivo. Furthermore, we observed that METTL3-mediated m6A regulated the degradation of FOXO1 mRNA through YTHDF2, a m6A binding protein. CONCLUSIONS METTL3-regulated m6A promotes YTHDF2-mediated decay of FOXO1 mRNA, thereby affecting cellular decidualization and embryo implantation. These findings provide novel insights into the development of therapies for women with endometriosis-related infertility.

Abstract
In brief Inflammation and abnormal immune response are the key processes in the development of endometriosis (EMs), and m6A modification can regulate the inflammatory response. This study reveals that METTL3-mediated N6-methyladenosine (m6A) modification plays an important role in EMs. Abstract m6A modification is largely involved in the development of different diseases. This study intended to investigate the implication of m6A methylation transferase methyltransferase like 3 (METTL3) in EMs. EMs- and m6A-related mRNAs and long non-coding RNAs were identified through bioinformatics analysis. Next, EM mouse models established by endometrial autotransplantation and mouse endometrial stromal cell (mESC) were prepared and treated with oe-METTL3 or sh-MIR17HG for pinpointing the in vitro and in vivo effects of METTL3 on EMs in relation to MIR17HG through the determination of mESC biological processes as well as estradiol (E2) and related lipoprotein levels. We demonstrated that METTL3 and MIR17HG were downregulated in the EMs mouse model. Overexpression of METTL3 suppressed the proliferation, migration, and invasion of mESCs. In addition, METTL3 enhanced the expression of MIR17HG through m6A modification. Moreover, METTL3 could inhibit the E2 level and alter related lipoprotein levels in EMs mice through the upregulation of MIR17HG. The present study highlighted that the m6A methylation transferase METTL3 prevents EMs progression by upregulating MIR17HG expression.

Silencing of circ_0007299 suppresses proliferation, migration, and invasiveness and promotes apoptosis of ectopic endometrial stromal cells in endometriosis via miR-424-5p-dependent modulation of CREB1. Arch Gynecol Obstet 2023; 307:149-161. [PMID: 35708784 DOI: 10.1007/s00404-022-06650-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 05/26/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The abnormality of endometrial stromal cells (ESCs) can contribute to endometriosis pathogenesis. Circular RNAs (circRNAs) possess critical roles in endometriosis pathogenesis. Here, we defined the activity and mechanism of human circ_0007299 in the regulation of ectopic ESCs in vitro. METHODS Circ_0007299, miR-424-5p and cAMP response element-binding protein 1 (CREB1) were quantified by qRT-PCR or immunoblotting. Cell viability, proliferation, apoptosis, invasion and motility were gauged by CCK-8, 5-Ethynyl-2'-Deoxyuridine (EdU), flow cytometry, transwell, and wound-healing assays, respectively. Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays were used to verify the direct relationship between miR-424-5p and circ_0007299 or CREB1. RESULTS Our data showed that circ_0007299 was upregulated in human ectopic endometrium tissues and ectopic ESCs. Silencing endogenous circ_0007299 impeded the proliferation, invasiveness, and motility and enhanced apoptosis of ectopic ESCs. Mechanistically, circ_0007299 regulated miR-424-5p expression. Moreover, circ_0007299 silencing impeded the proliferation, invasiveness, and motility and enhanced apoptosis of ectopic ESCs via its regulation on miR-424-5p. CREB1 was identified as a direct miR-424-5p target, and miR-424-5p overexpression suppressed ectopic ESC proliferation, migration, and invasiveness and promoted apoptosis by downregulating CREB1. Furthermore, circ_0007299 positively modulated CREB1 expression through miR-424-5p competition. CONCLUSION Our findings establish that circ_0007299 silencing impedes the proliferation, invasiveness, and motility and promotes apoptosis of ectopic ESCs at least in part via miR-424-5p-dependent modulation of CREB1.

Abstract
Increasing evidences have proved that circRNA plays a significant role in the development of many diseases. In addition, many researches have shown that circRNA can be considered as the potential biomarker for clinical diagnosis and treatment of disease. Some computational methods have been proposed to predict circRNA-disease associations. However, the performance of these methods is limited as the sparsity of low-order interaction information. In this paper, we propose a new computational method (KGANCDA) to predict circRNA-disease associations based on knowledge graph attention network. The circRNA-disease knowledge graphs are constructed by collecting multiple relationship data among circRNA, disease, miRNA and lncRNA. Then, the knowledge graph attention network is designed to obtain embeddings of each entity by distinguishing the importance of information from neighbors. Besides the low-order neighbor information, it can also capture high-order neighbor information from multisource associations, which alleviates the problem of data sparsity. Finally, the multilayer perceptron is applied to predict the affinity score of circRNA-disease associations based on the embeddings of circRNA and disease. The experiment results show that KGANCDA outperforms than other state-of-the-art methods in 5-fold cross validation. Furthermore, the case study demonstrates that KGANCDA is an effective tool to predict potential circRNA-disease associations.

Vascul Pharmacol 2021; 142:106932.

Abstract
17β-estradiol (E2) plays a key role in endometriosis through regulation of angiogenesis. Smad1 has been reported to be up-regulated in patients with endometriosis. However, the role of Smad1 in E2-mediated angiogenesis during the development of endometriosis remains to be determined. This study aimed to explore the role of Smad1 in E2-mediated angiogenesis during endometriosis and its underlying mechanisms. Immunofluorescence staining and Western blotting were performed to examine the expression of p-Smad1 in ectopic and control endometrium. Western blotting was used to examine activation of Smad1 signaling in NMECs, EMECs and HUVECs. Tube formation assay was performed to examine the effect of E2 on angiogenesis. Cell proliferation and migration was determined using in real-time by xCELLigence RTCA DP instrument. We found that the expression of p-Smad1 was significantly up-regulated in ectopic endometrium and ectopic intima microvascular endothelial cells. E2 non-genomically stimulated phosphorylation of Smad1 in HUVECs. c-Src and p44/42 MAPK(ERK1/2) signaling pathways are required for E2's induction on Smad1 phosphorylation. Moreover, caveolae is involved in E2-induced Smad1 phosphorylation in vascular endothelial cells. E2 promoted tube formation of vascular endothelial cells through c-Src/ERK1/2/Smad1 signaling pathway. Knockdown of Smad1 expression attenuated E2-induced proliferation and migration of HUVECs. In conclusion, E2 promotes proliferation, migration and tube formation of HUVECs through c-Src/ERK1/2/Smad1 signaling pathway. Our data shed new lights on the mechanisms through which E2 contributes to endometriosis, and may provide novel strategies to treat endometriosis.

Abstract
The occurrence of radioresistance is a clinical obstacle to endometrial cancer (EC) treatment and induces tumor relapse. In this study, we found that tumor-associated macrophages (TAMs) enriched in EC specimens were determined to present an M2-like phenotype. In vitro, the coculture of M2-polarized macrophages significantly downregulated the radiosensitivity of EC cells by releasing exosomes. Hsa_circ_0001610 was found to be abundant in exosomes derived from M2-polarized macrophages (EXOs), and hsa_circ_0001610 knockdown eliminated the reduction effect of EXOs on the radiosensitivity of EC cells. The following mechanism research revealed that hsa_circ_0001610 functioned as the competing endogenous RNA of miR-139-5p, thereby upregulating cyclin B1 expression, which is a vital pusher of radioresistance in several types of cancer by regulating the cell cycle. Hsa_circ_0001610 overexpression reduced the radiosensitivity of EC cells, which was then reversed by miR-139-5p overexpression. In vivo, the promotion effect of EXOs on xenograft tumor growth in nude mice treated with irradiation was further reinforced after hsa_circ_0001610 overexpression. In conclusion, TAM-derived exosomes transferred hsa_circ_0001610 to EC cells, and the overexpressed hsa_circ_0001610 in EC cells released cyclin B1 expression through adsorbing miR-139-5p, thereby weakening the radiosensitivity of EC cells.

Abstract
Endometriosis is a common gynecological disease, affecting up to 10% of women of reproductive age and approximately 50% of women with infertility. Circular RNAs (circRNAs) have been shown to be involved in a number of diseases. Dysregulated expression of circRNAs in endometriosis has been reported, and circ_0000673 was significantly downregulated. However, the details of its role in the pathogenesis of endometriosis are still poorly understood. We investigated the location and effects of the downregulation of circ_0000673 in endometriosis. We demonstrated that knockdown of circ_0000673 significantly increased the proliferation and migration of eutopic and normal endometrial cells. Bioinformatics analysis predicted that circ_0000673 might act as a sponge for miR-616-3p. We found that the effect of circ_0000673 knockdown could be recovered by miR-616-3p inhibitor and enhanced by miR-616-3p mimics. qPCR and western blot assays showed that circ_0000673 knockdown could decrease the expression of PTEN and increase the expression of PI3K and p-AKT. PTEN was confirmed to be a target of miR-616-3p. These results demonstrated that the downregulation of circ_0000673 could promote the progression of endometriosis by inactivating PTEN via the deregulation of miR-616-3p.

Abstract
Aim: To explore the circular RNA (circRNA) profile in cumulus cells from endometriosis-associated infertility patients. Methods: The expression of circRNAs was profiled by high-throughput sequencing. Sanger sequencing was performed to identify the backsplicing site. Six candidate circRNAs and their parental genes were measured in 30 samples by quantitative reverse transcription-polymerase chainreaction (qRT-PCR). Bioinformatics analysis was performed to predict the functions. Results: A total of 55 upregulated and 41 downregulated differentially expressed circRNAs were detected. Kyoto Encyclopedia of Genes and Genomes data indicated that these target genes were mainly involved in cumulus cell growth- and differentiation-related pathways. Hsa_circ_0072391, hsa_circ_0007299 and hsa_circ_0057799 were significantly increased, and hsa_circ_001533 was significantly decreased in endometriosis-associated infertility patients. Conclusion: The differentially expressed circRNAs might be potentially involved in pathophysiology of endometriosis-associated infertility.
