Reprod Biol Endocrinol 2022; 20:64. [PMID: 35379225 PMCID: PMC8978357 DOI: 10.1186/s12958-022-00928-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 03/13/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Our previous two-dimensional electrophoresis experiment showed that the expression of LASP1 in patients with endometriosis was significantly higher than that of control endometrium. However, the molecular mechanism by which LASP1 is regulated in endometriosis/adenomyosis is unknown. METHODS Herein, qPCR was performed to analyze the expression levels of LASP1 and miR-218-5p between endometriosis (Ems) cells and control cells. Fluorescence in situ hybridization was carried out to measure the expression level of miR-218-5p in ectopic endometrium versus normal endometrium. After miR-218-5p mimic or inhibitor were transfected, the transwell experiment was carried out to see the effect of miR-218-5p on the migration of endometrial stromal cells (ESCs). EdU was used to measure cell proliferation rate. Dual-luciferase reporter assay was used to verify the binding of hsa-miR-218-5p to the 3'UTR of LASP1. Western blot and immunofluorescence analysis were carried out to identify the protein expression pattern of LASP1 and EMT markers in endometrial tissue. RESULTS The miR-218-5p is mainly secreted from blood vessels and expressed in the muscle layer around the endometrium, which inhibits the expression level of LASP1 by binding the 3'UTR region of LASP1 in normal ESCs. Overexpression of miR-218-5p impedes the epithelial-to-mesenchymal transition (EMT) and prevents the migration of ESCs and the expression of Vimentin in Ems. CONCLUSIONS Our findings revealed that miR-218-5p in endometrial microenvironment prevents the migration of ectopic endometrial stromal cells by inhibiting LASP1.

Abstract
Myocardial infarction is one of the major causes of mortality worldwide and is a main cause of heart failure. This disease appears as a final point of atherosclerotic plaque progression, destabilization, and rupture. As a consequence of cardiomyocytes death during the infarction, the heart undergoes unfavorable cardiac remodeling, which results in its failure. Therefore, therapies aimed to limit the processes of atherosclerotic plaque progression, cardiac damage during the infarction, and subsequent remodeling are urgently warranted. A hopeful therapeutic option for the future medicine is targeting and regulating non-coding RNA (ncRNA), like microRNA, circular RNA (circRNA), or long non-coding RNA (lncRNA). In this review, the approaches targeted at ncRNAs participating in the aforementioned pathophysiological processes involved in myocardial infarction and their outcomes in preclinical studies have been concisely presented.

Abstract
Transforming growth factor-beta 1 (TGF-β1) plays important roles in the endothelial-to-mesenchymal transition (EndMT). Recently, long noncoding RNAs (lncRNAs) have been identified to be involved in the physiological and pathological processes of human diseases. However, the role of endothelial lncRNAs in the TGF-β1-mediated control of angiogenesis and its underlying mechanism remains largely unclear. In this study, we first demonstrated that TGF-β1 induced EndMT; promoted cell viability, proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs). Second, our study displayed that TGF-β1 upregulated the lncRNA UCA1 expression in HUVECs, knocked down UCA1 with small interfering RNAs, and inhibited the function of TGF-β1 in HUVECs. Third, our study showed that UCA1 was located in the cytoplasm and absorbed miR-455 in TGF-β1-treated HUVECs. Further, the miR-455 inhibitor restored the role of the inhibited UCA1 in HUVECs treated with TGF-β1. Fourth, our study revealed that miR-455 inhibited ZEB1 expression, and overexpression of ZEB1 restored the role of miR-455 in HUVECs treated with TGF-β1. Finally, our study revealed that UCA1 exerted its role via regulating the UCA1/miR-455/ZEB1 regulatory axis in HUVECs treated with TGF-β1. Collectively, our study identified the role of the UCA1/miR-455/ZEB1 pathway in HUVECs treated with TGF-β1 and indicated the potential therapeutic role of this regulatory axis in angiogenesis.

Abstract
Renal fibrosis is a key factor in chronic kidney disease (CKD). Long non-coding RNAs (lncRNAs) play important roles in the physiological and pathological progression of human diseases. However, the roles and underlying mechanisms of lncRNAs in renal fibrosis still need to be discovered. In this study, we first displayed the increased lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) expression in renal fibrosis in patients with obstructive nephropathy (ON). Then we found that transforming growth factor beta 1 (TGF-β1) induced epithelial-mesenchymal transition (EMT) and extracellular matrix (ECM) protein deposition, which promoted the viability, proliferation and migration of human renal proximal tubular epithelial (HK2) cells. Next, MALAT1/miR-145/focal adhesion kinase (FAK) pathway was confirmed to play an importment role in TGF-β1-induced renal fibrosis. In addition, the MALAT1/miR-145/FAK pathway was involved in the effect of dihydroartemisinin (DHA) on TGF-β1-induced renal fibrosis in vitro and in vivo. Furthermore, m6A methyltransferase methyltransferase-like 3 (METTL3) was shown to be the main methyltransferase of m6A modification on MALAT1.

Abstract
Glaucoma filtration surgery (GFS) is a classic surgical method used to treat glaucoma, the second leading cause of blindness. Scar formation caused by excessive Tenon's capsule fibroblast activation leads to surgical failure. However, the mechanism underlying this activation is largely unknown. In this study, we first isolated primary human Tenon's capsule fibroblasts (HTFs) and found that TGF-β promoted the viability, proliferation and extracellular matrix (ECM) deposition of HTFs. Then, we showed that TGF-β promoted the expression of H19 in HTFs and that suppression of H19 inhibited the effect of TGF-β on HTFs. Furthermore, we revealed that H19 exerted its effects by interacting with miR-200a in TGF-β-treated HTFs. Additionally, we showed that β-catenin was a target of miR-200a in TGF-β-treated HTFs. We also demonstrated that H19 acted by modulating the H19/miR-200a/β-catenin regulatory axis in TGF-β-treated HTFs. Ultimately, we found that the components of the H19/miR-200a/β-catenin regulatory axis were aberrantly expressed in a rat model of GFS. Our results show that H19 indeed acts by modulating β-catenin expression via miR-200a in TGF-β-treated HTFs, thus providing a novel rationale for the development of H19-based strategies to attenuate scar formation after GFS.

Abstract
Kidney fibrosis is usually the final manifestation of a wide variety of renal diseases. Recent years, research reported that long non-coding RNAs (lncRNAs) played important roles in a variety of human diseases. However, the role and underlying mechanisms of lncRNAs in kidney fibrosis were complicated and largely unclear. In our study, we constructed the cell model of renal fibrosis in HK2 cells using transforming growth factor β1 (TGF-β1) and found that lncRNA maternally expressed gene 3 (MEG3) was downregulated in TGF-β1-induced renal fibrosis. We then found that overexpressed MEG3 inhibited the TGF-β1-induced promotion of epithelial-mesenchymal transition, cell viability, and proliferation. Furthermore, we demonstrated that DNA methyltransferases 1 (DNMT1) regulated the MEG3 expression by altering the CpGs methylation level of MEG3 promoter in TGF-β1-induced renal fibrosis. In addition, we further revealed that miR-185 could regulate the DNMT1 expression and thus, modulate the MEG3 in TGF-β1-induced renal fibrosis. Ultimately, our study illustrated that the modulation of the miR-185/ DNMT1/ MEG3 pathway exerted important roles in TGF-β1-induced renal fibrosis. In summary, our finding displayed a novel regulatory mechanism for TGF-β1-induced renal fibrosis, which provided a new potential therapeutic target for renal fibrosis.

Abstract
Cystitis glandularis (CG) is an unusual proliferative disorder of the urinary bladder. Increasing evidences demonstrated that long non-coding RNAs (lncRNAs) play important roles in a variety of cellular progresses. However, there are rarely reports about the role and underlying molecular mechanism of lncRNAs in CG. In this study, we firstly isolated the primary cells from the tissues of CG and adjacent normal tissues, and found that UCA1 was up-regulated in the primary CG cells (pCGs). Then, we showed that knock out of UCA1 reduced the cell viability, inhibited the cell proliferation and restrained the migration potential and overexpression of UCA1 promoted that in pCGs. Furthermore, we demonstrated that UCA1 played its role via sponging of the miR-204 in pCGs. In addition, we illustrated that miR-204 exerted its function via targeting CYCLIN D2 (CCND2) 3'UTR at mRNA level in pCGs. Ultimately, we revealed the role and regulation of UCA1/miR-204/CCND2 regulatory axis in pCGs. In summary, our study, for the first time, revealed the role and underlying mechanism of an lncRNA UCA1 in CG, providing a potential biomarker and therapeutic target for human CG.

Abstract
Colorectal cancer (CRC) is the one of the most common malignant tumors worldwide. Recent years, widespread long non-coding RNAs (lncRNAs) have been discovered and are known to regulate gene expression in cancers. However, the roles and underlying mechanisms of lncRNA in CRC remain largely unclear. Here, we firstly revealed that repression of lncRNA nuclear paraspeckle assembly transcript 1 (NEAT1) inhibited cell proliferation and migration in HCT116 cells and overexpression of NEAT1 promoted cell proliferation and migration in SW480 cells using CCK8 assay and transwell assay. Then, we found that suppression of NEAT1 increased the miR-196a-5p expression in HCT116 cells, while elevation of NEAT1 decreased the miR-196a-5p expression in SW480 cells using qPCR assay. Furthermore, miR-196a-5p could bind to the predicted binding site of NEAT1. We then found that miR-196a-5p was involved in the role of NEAT1 in CRCs. In addition, we demonstrated that miR-196a-5p mimics inhibited the glial cell-derived neurotrophic factor (GDNF) expression in HCT116 cells and meanwhile, miR-196a-5p inhibitor promoted GDNF expression in SW480 cells using qPCR and western blot analysis. Then, we proved that miR-196a-5p exerted its function via regulating GDNF expression in CRCs. Ultimately, our study demonstrated that NEAT1 exerted its role via miR-196a-5p/GDNF axis in CRCs. In summary, this work provided the first evidence of a NEAT1/miR-196a-5p/GDNF regulatory pathway in CRC.

Abstract
Excessive adiposity has long been proved to be associated with greater incidence and mortality of breast cancer in post-menopausal women. However, the effects and underlying mechanisms of human adipocytes on breast cancer cells remain largely unknown. In recent years, several reports have revealed the oncogenic role of long non-coding RNA PVT1 in breast cancer. Here, we aimed to investigate the role and underlying mechanisms of PVT1 in triple-negative breast cancer (TNBC) cells cultured with mature adipogenic medium. At first, we successfully induced adipogenic differentiation from human adipose-derived mesenchymal stem cells and collected the mature adipogenic medium to mimic excessive adiposity. Our results demonstrated that the mature adipogenic medium promoted the epithelial-mesenchymal transition, enhanced the cell viability and migration potential of TNBC cells. In addition, we proved that mature adipogenic medium affected the PVT1 expression and inhibition of the PVT1 disturbed the role of mature adipogenic medium in TNBC cells. Finally, we illustrated that repression of p21 restored the phenotype caused by PVT1 knockdown in TNBC cells treated with mature adipogenic medium. Taken together, our results demonstrated that PVT1 affected the role of mature adipogenic medium in TNBC cells via modulating p21 expression.

Abstract
Increasing epidemic of type 2 diabetes mellitus (T2DM) and its comorbidities makes it urgent to understand the pathogenesis and regulatory mechanism. However, little is known about the regulatory role of lncRNAs in diabetes. Here, we constructed a T2DM‐related competitive endogenous RNA (ceRNA) network (DMCN) to explore biological function of lncRNAs during the development of diabetes mellitus. This network contained 351 nodes including 98 mRNAs, 86 microRNAs and 167 lncRNAs. Functional analysis showed that the mRNAs in DMCN were annotated into some diabetes‐related pathways. Furthermore, mTOR‐centred subnetwork was extracted and ncRNA‐involved mTOR pathway was established. Finally, we validated that NEAT1 was potentially communicated with mTOR signalling target protein mLST8 via the association with miR‐181b. These findings provide significant insight into lncRNA regulatory network in T2DM.

Abstract
Thyroid cancer (TC) is the most common endocrine malignancy. Lack of effective early diagnostic tools is one of the clinical obstacles for TC treatment. Thus, enhanced comprehension of the molecular changes in TC tumorigenesis is urgently needed to develop novel strategies for the diagnosis and treatment of TC. Long non-coding RNAs (lncRNAs) manage fundamental biochemical and cellular processes in tumorigenesis and development. One of the best-described lncRNAs, HOX transcript antisense RNA (HOTAIR), functions as a regulatory molecule in a wide variety of biological processes, and represses gene expression through recruitment of the chromatin modifying complex. However, the function of HOTAIR in TC remains unclear. In the current study, the expression of HOTAIR is elevated in TC and correlates with metastasis and poor prognosis. Furthermore, the expression of HOTAIR is significantly upregulated in human thyroid carcinoma cells compared with normal human thyroid cells. Furthermore, knockdown of HOTAIR significantly inhibited cell growth and invasion in TPC-1 and SW579 human thyroid carcinoma. In summary, HOTAIR is a promising novel biomarker in patients with TC.

Abstract
Long noncoding RNAs (lncRNAs) represent a category of noncoding RNAs with the potential for genetic and epigenetic regulations. As important regulators of gene expression, increasing evidence has proven that lncRNAs play a significant regulatory role in various cardiovascular pathologies. In particular, lncRNAs have been proved to be participating in gene regulatory mechanisms involved in heart growth and development that can be exploited to repair the injured adult heart. Furthermore, lncRNAs have been revealed as possible therapeutic targets for heart failure with different causes and in different stages. In the journey from a healthy heart to heart failure, lncRNAs have been shown to participate in almost every landmark of heart failure pathogenesis including ischemic injury, cardiac hypertrophy, and cardiac fibrosis. Furthermore, the manipulation of lncRNAs palliates the progression of heart failure by attenuating ischemic heart injury, cardiac hypertrophy and cardiac fibrosis, as well as facilitating heart regeneration and therapeutic angiogenesis. This review will highlight recent updates regarding the involvement of lncRNAs in cardiac hypertrophy and heart failure and their potential as novel therapeutic targets. This article is part of a Special Issue entitled: Genetic and epigenetic control of heart failure - edited by Jun Ren & Megan Yingmei Zhang.

Abstract
Making quick promises of major biomedical breakthroughs based on exciting discoveries at the bench is tempting. But the meandering path from fundamental science to life-saving clinical applications can be fraught with many hurdles. Epigenetics, the study of potentially heritable changes of gene function without modification of the underlying DNA sequence, has dominated the biological research field during the last decade and encountered a large public success. Driven by the unfolding of molecular biology and recent technological progress, the term has evolved significantly and shifted from a conceptual framework to a mechanistic understanding. This shift was accompanied by much hype and raised high hopes that epigenetics might hold both the key to deciphering the molecular underpinning of complex, non-Mendelian diseases and offer novel therapeutic approaches for a large panel of pathologies. However, while exciting reports of biological phenomena involving DNA methylation and histone modifications fill up the scientific literature, the realistic clinical applications of epigenetic medicines remain somewhat blurry. Here, we discuss the state of the art and speculate how epigenetics might contribute to prognostic and therapy approaches in the future.

Abstract
In this review we highlight the role of non-coding RNAs in the development and progression of cardiac pathology and explore the possibility of disease-associated RNAs serving as targets for cardiac-directed therapeutics. Contextually, we focus on the role of stress-induced hypoxia as a driver of disease development and progression through activation of hypoxia inducible factor 1α (HIF1α) and explore mechanisms underlying HIFα function as an enforcer of cardiac pathology through direct transcriptional coupling with the non-coding transcriptome. In the interest of clarity, we will confine our analysis to cardiac pathology and focus on three defining features of the diseased state, namely metabolic, growth and functional reprogramming. It is the aim of this review to explore possible mechanisms through which HIF1α regulation of the non-coding transcriptome connects to spatiotemporal control of gene expression to drive establishment of the diseased state, and to propose strategies for the exploitation of these unique RNAs as targets for clinical therapy.

Abstract
miRNAs are small non-coding RNAs (ncRNAs), which regulate gene expression. Here, the authors describe the contribution of miRNAs to cardiac biology and disease. They discuss various strategies for manipulating miRNA activity including antisense oligonucleotides (antimiRs, blockmiRs), mimics, miRNA sponges, Tough Decoys and miRNA mowers. They review developments in chemistries (e.g., locked nucleic acid) and modifications (sugar, 'ZEN', peptide nucleic acids) and miRNA delivery tools (viral vectors, liposomes, nanoparticles, pHLIP). They summarize potential miRNA therapeutic targets for heart disease based on preclinical studies. Finally, the authors review current progress of miRNA therapeutics in clinical development for HCV and cancer, and discuss challenges that will need to be overcome for similar therapies to enter the clinic for patients with cardiac disease.
