Abstract
Premature ovarian failure (POF) represents the pathological aging of the ovary. The tRNA-derived small fragments (tsRNAs) play significant roles in diseases; however, whether tsRNAs are involved in POF remains unknown. The cell and mice models of POF were established, and the tsRNAs profile in the ovarian tissues of POF mice was revealed through sequencing. The functions of tsRNA-3043a and its target gene FLT1 in POF cells and mice were detected. POF mice were characterized by a decreased number of normal follicles, ovarian weight, SOD level, and serum contents of E2, LH, and FSH. A total of 81 tsRNAs were aberrantly expressed in the ovarian tissue of POF mice. The expression of tsRNA-3043a was up-regulated in POF mice. tsRNA-3043a mimics inhibited the proliferation and promoted apoptosis, lipid accumulation, and cellular senescence of ovarian granulosa KGN cells, as well as altered the transcriptome. tsRNA-3043a inhibitor had the opposite effect. tsRNA-3043a targets and binds to FLT1. Overexpression of FLT1 protected KGN cells from pathological aging. tsRNA-3043a promotes the progression of POF by inhibiting FLT1 in vitro and in vivo. tsRNA-3043a targets FLT1 and promotes apoptosis and senescence of ovarian granulosa cells, leading to the progression of POF. This study provides a new target for pharmacological intervention in POF.

Cancer Sci 2024. [PMID: 39318101 DOI: 10.1111/cas.16350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 09/04/2024] [Accepted: 09/07/2024] [Indexed: 09/26/2024] Open
Abstract
It is recognized that lncRNA BBOX1-AS1 exerts a crucial oncogenic property in several cancer types. However, the functions and underlying mechanisms of BBOX1-AS1 in the epithelial-mesenchymal transition (EMT) process of gastric cardia adenocarcinoma (GCA) have remained unclarified. The findings of this study demonstrated that GCA tissues had elevated BBOX1-AS1 expression levels, which was associated with a worse prognosis in GCA patients. BBOX1-AS1 dramatically enhanced cell proliferation, invasion, and TGF-β1-induced the EMT process in vitro. Further mechanism analysis revealed that BBOX1-AS1 could combine with CtBP2 and strengthen the interaction of CtBP2 and ZEB1. BBOX1-AS1 might regulate the E-cadherin expression through CtBP2/ZEB1 transcriptional complex-mediated transcriptional repression, further affecting the activation of the Wnt/β-catenin pathway and the EMT process. Overall, our findings demonstrate that BBOX1-AS1 might act as an lncRNA associated with EMT for facilitating GCA advancement via interaction with CtBP2 to facilitate the activation of Wnt/β-catenin pathway and the EMT process, which indicated that it might function as an exploitable treatment target for GCA patients.

Circ_0043314 Modulates Proliferation and Apoptosis of Ovarian Granulosa Cells in Polycystic Ovarian Syndrome via the MicroRNA-146b-3p/Apelin 13 Axis. Gynecol Obstet Invest 2024:1-12. [PMID: 39008951 DOI: 10.1159/000540097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 06/09/2024] [Indexed: 07/17/2024]
Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women. At present, the pathogenesis has not been clarified, and the clinical application of drugs and lifestyle intervention may not prevent disease progression. This study aimed to investigate how circ_0043314 regulates ovarian granulosa cell biological functions to provide a theoretical basis for the treatment of patients with PCOS. MicroRNA (miR)-146b-3p/Apelin 13 axis was used to investigate the mechanism by which circ_0043314 regulated ovarian granulosa cell proliferation and apoptosis in PCOS via miR-146b-3p/Apelin 13 axis. Participants/Materials, Methods: Ovarian tissues (cortical tissues) from 35 PCOS patients and 35 normal controls, as well as HEK293T and human ovarian granulosa cell line (KGN, COV434), were included in this study. We examined the expression levels of circ_0043314, miR-146b-3p, and Apelin 13 in PCOS tissues. Ovarian granulosa cells were transfected with corresponding plasmids to clarify the influence of circ_0043314, miR-146b-3p, or Apelin 13 on proliferation and apoptosis of ovarian granulosa cells through MTT and flow cytometry assays. Moreover, the relationships among circ_0043314, miR-146b-3p, and Apelin 13 were analyzed through dual-luciferase and RNA immunoprecipitation assays. RESULTS Circ_0043314 and Apelin 13 were highly expressed and miR-146b-3p was lowly expressed in ovarian tissues of PCOS compared with non-PCOS controls. Downregulation of circ_0043314 or upregulation of miR-146b-3p hindered ovarian granulosa cell proliferation and advanced its apoptosis. Downregulation of miR-146b-3p reversed the impacts of downregulation of circ_0043314, and overexpression of Apelin 13 counteracted the influences of upregulation of miR-146b-3p in ovarian granulosa cells. Mechanically, circ_0043314 could bind to miR-146b-3p, and miR-146b-3p directly targeted and modulated Apelin 13 expression. LIMITATIONS This study was limited by the lack of animal experiments. CONCLUSION Our data demonstrated that circ_0043314 enhances ovarian granulosa cell proliferation and suppresses its apoptosis via miR-146b-3p/Apelin 13 axis.

Abstract
Recent research findings have highlighted the pivotal roles played by lncRNAs in both normal human development and disease pathogenesis. LncRNAs are expressed in oocytes and early embryos, and their expression levels change dynamically once the embryonic genome is activated during early human embryonic development. Abnormal expression of lncRNAs was found in follicular fluid, granulosa cells and oocytes of patients, and these lncRNAs were related to cell proliferation and apoptosis, nuclear maturation and follicle development. The expression levels of some lncRNAs in cumulus cells demonstrate correlations with the quality of oocytes and early embryos. This paper aims to present a comprehensive overview of the influence of LncRNAs on the developmental process of human oocytes as well as their involvement in certain infertility-related diseases.

Anal Cell Pathol (Amst) 2023; 2023:4500810. [PMID: 38077523 PMCID: PMC10710365 DOI: 10.1155/2023/4500810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 11/03/2023] [Accepted: 11/13/2023] [Indexed: 12/18/2023] Open
Abstract
Background In the present study, we aimed to find out whether luteolin (Lut) pretreatment could ameliorate myocardial ischemia/reperfusion (I/R) injury by regulating the lncRNA just proximal to XIST (JPX)/microRNA-146b (miR-146b) axis. Methods We established the models in vitro (HL-1 cells) and in vivo (C57BL/6J mice) to certify the protection mechanism of Lut pretreatment on myocardial I/R injury. Dual luciferase reporter gene assay was utilized for validating that JPX could bind to miR-146b. JPX and miR-146b expression levels were determined by RT-qPCR. Western blot was utilized to examine apoptosis-related protein expression levels, including cleaved caspase-9, caspase-9, cleaved caspase-3, caspase-3, Bcl-2, Bax, and BAG-1. Apoptosis was analyzed by Annexin V-APC/7-AAD dualstaining, Hoechst 33342 staining, as well as flow cytometry. Animal echocardiography was used to measure cardiac function (ejection fraction (EF) and fractional shortening (FS) indicators). Results miR-146b was demonstrated to bind and recognize the JPX sequence site by dual luciferase reporter gene assay. The expression level of miR-146b was corroborated to be enhanced by H/R using RT-qPCR (P < 0.001 vs. Con). Moreover, JPX could reduce the expression of miR-146b, whereas inhibiting JPX could reverse the alteration (P < 0.001 vs. H/R, respectively). Western blot analysis demonstrated that Lut pretreatment increased BAG-1 expression level and Bcl-2/Bax ratio, but diminished the ratio of cleaved caspase 9/caspase 9 and cleaved caspase 3/caspase 3 (P < 0.001 vs. H/R, respectively). Moreover, the cell apoptosis change trend, measured by Annexin V-APC/7-AAD dualstaining, Hoechst 33342 staining, along with flow cytometry, was consistent with that of apoptosis-related proteins. Furthermore, pretreatment with Lut improved cardiac function (EF and FS) (P < 0.001 vs. I/R, respectively), as indicated in animal echocardiography. Conclusion Our results demonstrated that in vitro and in vivo, Lut pretreatment inhibited apoptosis via the JPX/miR-146b axis, ultimately improving myocardial I/R injury.

Abstract
Gamma-butyrobetaine hydroxylase 1 antisense RNA 1 (BBOX1-AS1), located on human chromosome 11 p14, emerges as a critical player in tumorigenesis with diverse oncogenic effects. Aberrant expression of BBOX1-AS1 intricately regulates various cellular processes, including cell growth, epithelial-mesenchymal transition, migration, invasion, metastasis, cell death, and stemness. Notably, the expression of BBOX1-AS1 was significantly correlated with clinical-pathological characteristics and tumor prognoses, and it could also be used for the diagnosis of lung and esophageal cancers. Through its involvement in the ceRNA network, BBOX1-AS1 competitively binds to eight miRNAs in ten different cancer types. Additionally, BBOX1-AS1 can directly modulate downstream protein-coding genes or act as an mRNA stabilizer. The implications of BBOX1-AS1 extend to critical signaling pathways, including Hedgehog, Wnt/β-catenin, and MELK/FAK pathways. Moreover, it influences drug resistance in hepatocellular carcinoma. The present study provides a systematic review of the clinical significance of BBOX1-AS1's aberrant expression in diverse tumor types. It sheds light on the intricate molecular mechanisms through which BBOX1-AS1 influences cancer initiation and progression and outlines potential avenues for future research in this field.

Abstract
Ten percent of people who are of reproductive age experience infertility. Sometimes the most effective therapies, including technology for assisted reproduction, may lead to unsuccessful implantation. Because of the anticipated epigenetic alterations of in vitro as well as in vitro fertilization growth of embryos, these fertility techniques have also been linked to unfavorable pregnancy outcomes linked to infertility. In this regard, a variety of non-coding RNAs such as long noncoding RNAs (lncRNAs) act as epigenetic regulators in the various physiological and pathophysiological events such as infertility. LncRNAs have been made up of cytoplasmic and nuclear nucleotides; RNA polymerase II transcribes these, which are lengthier than 200 nt. LncRNAs perform critical roles in a number of biological procedures like nuclear transport, X chromosome inactivation, apoptosis, stem cell pluripotency, as well as genomic imprinting. A significant amount of lncRNAs were linked into a variety of biological procedures as high throughput sequencing technology advances, including the development of the testes, preserving spermatogonial stem cells' capacity for differentiation along with self-renewal, and controlling spermatocyte meiosis. All of them point to possible utility of lncRNAs to be biomarkers and treatment aims for female infertility. Herein, we summarize various lncRNAs that are involved in female infertility.

Abstract
Long non-coding RNAs (lncRNAs) are transcripts that contain more than 200 nucleotides. Despite the fact that they cannot encode proteins, many studies have identified roles they play in human cancers through diverse mechanisms. BBOX1-AS1, an oncogenic lncRNA, has recently been demonstrated to participate in tumorigenesis and progression of numerous cancers. Experimental evidence has determined that it participates in diverse biological process, including cell proliferation, invasion, migration, and apoptosis. The dysregulation of BBOX1-AS1 exerts its oncogenicity by acting as a competitive endogenous RNA (ceRNA) or by directly impacting downstream molecules and signaling pathways. Here we summarize the current understanding of the biological functions and clinical significance of BBOX1-AS1 for human cancers.

Therapeutic effects of human umbilical cord mesenchymal stem cell-derived extracellular vesicles on ovarian functions through the PI3K/Akt cascade in mice with premature ovarian failure.

Abstract
Premature ovarian failure (POF) mainly refers to ovarian dysfunction in females younger than forty. Mesenchymal stem cells (MSCs) are considered an increasingly promising therapy for POF. This study intended to uncover the therapeutic effects of human umbilical cord MSC-derived extracellular vesicles (hucMSCEVs) on POF. hucMSCs were identified by observing morphology and examining differentiation capabilities. EVs were extracted from hucMSCs and later identified utilizing nanoparticle tracking analysis, transmission electron microscopy, and Western blotting. POF mouse models were established by injecting D-galactose (Dgal). The estrous cycles were assessed through vaginal cytology, and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-mullerian hormone (AMH), estradiol (E2), and progesterone (P) were measured by ELISA. The human ovarian granulosa cell line KGN was used for in vitro experiments. The uptake of hucMSC-EVs by KGN cells was detected. After D-gal treatment, cell proliferation and apoptosis were assessed via CCK-8 assay and flow cytometry. The PI3K/Akt pathway-related proteins were determined by Western blotting. Our results revealed that POF mice had prolonged estrous cycles, increased FSH and LH levels, and decreased AMH, E2, and P levels. Treatment with hucMSC-EVs partially counteracted the above changes. D-gal treatment reduced proliferation and raised apoptosis in KGN cells, while hucMSC-EV treatment annulled the changes. D-gal-treated cells exhibited downregulated p-PI3K/PI3K and p-Akt/Akt levels, while hucMSC-EVs activated the PI3K/Akt pathway. LY294002 suppressed the roles of hucMSC-EVs in promoting KGN cell proliferation and lowering apoptosis. Collectively, hucMSC-EVs facilitate proliferation and suppress apoptosis of ovarian granulosa cells by activating the PI3K/Akt pathway, thereby alleviating POF.

Abstract
CONTEXT Primary ovarian insufficiency (POI) is a heterogeneous disease with an unknown underlying trigger or root cause. Recently many studies evaluated noncoding RNAs (ncRNAs), especially microRNAs (miRNAs), long noncoding RNA (lncRNAs), circular RNAs (circRNAs), and small interfering RNAs (siRNAs) for their associations with POI. EVIDENCE ACQUISITION In this review, we outline the biogenesis of various ncRNAs relevant to POI and summarize the evidence for their roles in the regulation of disease occurrence and progression. Articles from 2003 to 2022 were selected for relevance, validity, and quality from results obtained in PubMed and Google Scholar using the following search terms: noncoding RNAs; primary ovarian insufficiency; premature ovarian failure; noncoding RNAs and primary ovarian insufficiency/premature ovarian failure; miRNAs and primary ovarian insufficiency/premature ovarian failure; lncRNAs and primary ovarian insufficiency/premature ovarian failure; siRNAs and primary ovarian insufficiency/premature ovarian failure; circRNAs and primary ovarian insufficiency/premature ovarian failure; pathophysiology; and potential treatment. All articles were independently screened for eligibility by the authors. EVIDENCE SYNTHESIS This review summarizes the biological functions and synthesis of miRNAs, lncRNAs, siRNAs, and circRNAs in POI and discusses the findings of clinical and in vitro and in vivo studies. Although there is variability in the findings of individual studies, overall the available literature justifies the conclusion that dysregulated ncRNAs play significant roles in POI. CONCLUSION The potential of ncRNAs in the treatment of POI requires further investigation, as ncRNAs derived from mesenchymal stem cell-secreted exosomes play pivotal roles and have considerable therapeutic potential in a multitude of diseases.

Abstract
Aims: To explore whether the expression of pyroptosis-related lncRNAs makes a difference in the prognosis and antitumor immunity of cutaneous melanoma (CM) patients. Methods: A series of analyses were conducted to establish a prognostic risk model and validate its accuracy. Immune-related analyses were performed to further assess the associations among immune status, tumor microenvironment and the prognostic risk model. Results: Eight pyroptosis-related lncRNAs relevant to prognosis were ascertained and applied to establish the prognostic risk model. The low-risk group had a higher overall survival rate. Conclusion: The established prognostic risk model presents better prediction ability for the prognosis of CM patients and provides new possible therapeutic targets for CM.

[PMID: 36634743 DOI: 10.1016/j.yexcr.2023.113473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 01/03/2023] [Accepted: 01/08/2023] [Indexed: 01/11/2023]
Abstract
Long non-coding RNA (lncRNA) anomalies cause early ovarian failure. LncRNA nuclear enriched abundant transcript 1 (NEAT1) was down-regulated in premature ovarian failure (POF) mice and connected to the illness, however, the mechanism remained unclear. The levels of gene and protein were measured by using quantitative real-time polymerase chain reaction, Western blot, and immunofluorescence. Follicle stimulating hormone (FSH), estradiol (E2), and luteinizing hormone (LH) levels were determined using enzyme-linked immunosorbent assay (ELISA). 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and flow cytometry were used to determine cell viability and apoptosis. The interaction of NEAT1, miR-654, and stanniocalcin-2 (STC2) was verified by dual-luciferase reporter assay or RNA binding protein immunoprecipitation (RIP) assays. The results showed NEAT1 and STC2 down-regulated, while miR-654 up-regulated in POF mice. Overexpression of NEAT1 reduced apoptosis and autophagy in cyclophosphamide (CTX)-treated ovarian granulosa cells (OGCs), and Bax, cleaved-caspase3, LC3B, LC3II/LC3I ratio were decreased and Bcl-2 and p62 were raised. NEAT1 suppressed miR-654 expression by directly targeting miR-654. The inhibition of NEAT1 overexpression on apoptosis and autophagy in OGCs was reversed by miR-654 mimics. STC2 was a target gene of miR-654, and miR-654 inhibitor reduced the apoptosis and autophagy by regulating the STC2/MAPK axis. To sum up, NEAT1 reduced miR-654 expression and modulated the STC2/MAPK pathway to decrease apoptosis and autophagy in POF, indicating a potential therapeutic target.

Abstract
Premature ovarian failure (POF), or premature ovarian insufficiency (POI), is a multifactorial and heterogeneous disease characterized by amenorrhea, decreased estrogen levels and increased female gonadotropin levels. The incidence of POF is increasing annually, and POF has become one of the main causes of infertility in women of childbearing age. The etiology and pathogenesis of POF are complex and have not yet been clearly elucidated. In addition to genetic factors, an increasing number of studies have revealed that epigenetic changes play an important role in the occurrence and development of POF. However, we found that very few papers have summarized epigenetic variations in POF, and a systematic analysis of this topic is therefore necessary. In this article, by reviewing and analyzing the most relevant literature in this research field, we expound on the relationship between DNA methylation, histone modification and non-coding RNA expression and the development of POF. We also analyzed how environmental factors affect POF through epigenetic modulation. Additionally, we discuss potential epigenetic biomarkers and epigenetic treatment targets for POF. We anticipate that our paper may provide new therapeutic clues for improving ovarian function and maintaining fertility in POF patients.

Human Umbilical Cord Mesenchymal Stem Cells Improve Premature Ovarian Failure through Cell Apoptosis of miR-100-5p/NOX4/NLRP3. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3862122. [PMID: 35845923 PMCID: PMC9283025 DOI: 10.1155/2022/3862122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 06/02/2022] [Accepted: 06/07/2022] [Indexed: 11/17/2022]
Abstract
Premature ovarian failure refers to a series of symptoms of perimenopausal hot flashes, night sweats, decreased libido, vaginal dryness, insomnia, reduced menstruation, sparse hair, even amenorrhea, and even infertility before the age of 40 due to the decline of ovarian function. Premature ovarian failure is a common and difficult disease in gynecology. Its prevalence is increasing gradually, and the trend is younger. The aim of this experiment was to elucidate the role of human umbilical cord mesenchymal stem cells (HUCMSCs) in premature ovarian failure and its mechanism. HUCMSCs, KGN cells, and HEK293T cells were used in this experiment. Quantitative PCR and microarray analysis, ELISA inflammation and oxidative stress kits, RNA pull-down assay, luciferase reporter assay, proliferation assay, EDU staining, and Western blot analysis were used. In an in vitro model of premature ovarian failure, HUCMSCs attenuated inflammatory response, oxidative stress, and apoptosis. HUCMSCs ameliorated the premature ovarian failure model. The miR-100-5p expression was induced by HUCMSCs through methylation. miR-100-5p regulation influenced the role of HUCMSCs in an in vitro model of premature ovarian failure. HUCMSCs inhibited the in vitro expression of NOX4, NLRP3, and GSDMD proteins in the model. NOX4/NLRP3 signaling pathway affects the role of HUCMSCs in an in vitro model of premature ovarian failure through miR-100-5p. This experiment elucidated the role of HUCMSCs in premature ovarian failure and its mechanism, with a view to providing a clinical reference.
