Abstract
BACKGROUND Human aortic vascular smooth muscle cells (HA-VSMCs) play vital roles in the pathogenesis of vascular diseases. Circular RNAs (circRNAs) have been reported to regulate the biological functions of HA-VSMCs. In this study, the functions of circRNA pecanex homolog (circPCNX) in platelet-derived growth factor-BB (PDGF-BB)-induced HA-VSMCs were investigated. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the expression of circPCNX, DNA methyltransferase 1 (DNMT1), and microRNA-1278 (miR-1278). 5'-Ethynyl-2'-deoxyuridine (EdU) assay, flow cytometry analysis, wound healing assay, and transwell assay were used to examine cell proliferation, cell cycle, and migration. Western blot assay was utilized to measure protein levels. RNA immunoprecipitation (RIP) assay, RNA pull down assay, and dual-luciferase reporter assay were adopted to analyze the relationships among circPCNX, miR-1278, and DNMT1. RESULTS CircPCNX was upregulated in PDGF-BB-treated HA-VSMCs in a dose- or time-dependent manner. CircPCNX knockdown alleviated PDGF-BB-induced cell proliferation, cell cycle progression, and migration in HA-VSMCs. CircPCNX knockdown could reverse PDGF-BB-induced HA-VSMC progression by regulating DNMT1. Moreover, circPCNX was identified to regulate DNMT1 expression by sponging miR-1278. Inhibition of miR-1278 reversed circPCNX knockdown-mediated effects on cell proliferation and migration in PDGF-BB-induced HA-VSMCs. MiR-1278 overexpression suppressed PDGF-BB-stimulated HA-VSMC proliferation and migration by targeting DNMT1. CONCLUSION CircPCNX promoted PDGF-BB-induced HA-VSMC proliferation and migration by elevating DNMT1 expression through sponging miR-1278.

[PMID: 37445481 DOI: 10.3390/jcm12134446] [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: 05/21/2023] [Revised: 06/26/2023] [Accepted: 06/29/2023] [Indexed: 07/15/2023] Open
Abstract
Much attention has been paid lately to harnessing the diagnostic and therapeutic potential of non-coding circular ribonucleic acids (circRNAs) and micro-RNAs (miRNAs) for the prevention and treatment of cardiovascular diseases. The genetic environment that contributes to atherosclerosis pathophysiology is immensely complex. Any potential therapeutic application of circRNAs must be assessed for risks, benefits, and off-target effects in both the short and long term. A search of the online PubMed database for publications related to circRNA and atherosclerosis from 2016 to 2022 was conducted. These studies were reviewed for their design, including methods for developing atherosclerosis and the effects of the corresponding atherosclerotic environment on circRNA expression. Investigated mechanisms were recorded, including associated miRNA, genes, and ultimate effects on cell mechanics, and inflammatory markers. The most investigated circRNAs were then further analyzed for redundant, disparate, and/or contradictory findings. Many disparate, opposing, and contradictory effects were observed across experiments. These include levels of the expression of a particular circRNA in atherosclerotic environments, attempted ascertainment of the in toto effects of circRNA or miRNA silencing on atherosclerosis progression, and off-target, cell-specific, and disease-specific effects. The high potential for detrimental and unpredictable off-target effects downstream of circRNA manipulation will likely render the practice of therapeutic targeting of circRNA or miRNA molecules not only complicated but perilous.

Abstract
Background Intra-articular inflammation and cartilage degradation are the major pathological characteristics of osteoarthritis (OA). Mounting studies have revealed that circular RNAs (circRNAs) act as an important regulatory role in inflammatory diseases and are frequently dys-expressed in OA cartilage tissues. Objective Here, a dys-regulated cicrRNA (has_circ_0017636, termed circSFMBT2-OA) was identified, and its role in regulating lipopolysaccharide (LPS)-induced chondrocyte injury was next investigated. Methods CHON-001 chondrocytes were treated with LPS, and then the levels of circSFMBT2-OA, cartilage-related genes, and pro-inflammatory cytokines were measured using quantitative real-time PCR (qRT-PCR) and Western blot analysis. CHON-001 cell viability, proliferation, and apoptosis were assayed using Cell Counting Kit-8 (CCK-8), 5-Ethynyl-2'-deoxyuridine (EDU), and terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) assay, respectively. Results CircSFMBT2-OA level was significantly down-regulated in OA cartilage tissues and LPS-treated CHON-001 cells. Functionally, circSFMBT2-OA overexpression accelerated cell proliferation, and suppressed cell apoptosis, pro-inflammatory cytokines production, matrix-degrading enzymes expression, and ECM degradation in CHON-001 cells. Inversely, circSFMBT2-OA depletion decreased cell viability and increased matrix-degrading enzymes expression and ECM degradation. Mechanistically, circSFMBT2-OA inhibited LPS-induced NF-κB/NOD-like receptor family pyrin domain containing protein 3 (NLRP3) inflammasome activation in CHON-001 cells. Consequently, NLRP3 activator reversed the effect of circSFMBT2-OA on repressing LPS-induced CHON-001 cell injury. Conclusion These data reveal a vital effect of a novel circSFMBT2-OA on repressing OA progression and provide a promising target to treat OA.

Abstract
Circular RNAs (circRNAs) are a class of non-coding RNAs that have cell-type-specific expression and are relevant in cardiovascular disease. Aortic smooth muscle cells (SMCs) play a crucial role in cardiovascular disease. In this study, we employed a systems genetics approach to identify SMC circRNA transcripts and their relevance in cardiovascular traits across the genome. We quantified circRNA expression across 151 quiescent and proliferative human aortic SMCs from donors of various genetic ancestries. We identified 1,589 expressed circRNAs. Between quiescent and proliferative SMCs, we identified 173 differentially expressed circRNAs. To characterize the genetic regulation of circRNA expression, we associated the genotypes of 6.3 million single nucleotide polymorphisms (SNPs) with circRNA abundance and found 96 circRNAs that were associated with genetic loci. Three SNPs were associated with circRNA expression in proliferative SMCs but not quiescent SMCs. We identified six SNPs that had distinct association directions with circRNA isoforms from the same gene. Lastly, to identify the relevance of circRNAs in cardiovascular disease, we overlapped genetic loci associated with circRNA expression with vascular disease-related genome-wide association studies loci. We identified 14 blood pressure, one myocardial infarction, and three coronary artery disease loci, which were associated with a circRNA transcript but not an mRNA transcript. Overall, our results provide insight into the genetic basis of vascular disease traits mediated by circRNA expression.

Abstract
Atherosclerosis is the major pathophysiological basis of cerebrovascular and cardiovascular diseases. Vascular smooth muscle cells (VSMCs) constitute the main structure of vasculature and play important roles in maintaining vascular tone and blood pressure. Many biological processes and cellular signaling events involved in atherosclerogenesis have been shown to converge on deregulating VSMC functions. However, the molecular mechanisms underlying dysfunctional VSMC in atherosclerosis are still poorly defined. Recent evidence revealed that circular RNAs (circRNAs) are closely related to diseases such as degenerative diseases, tumor, congenital diseases, endocrine diseases and cardiovascular diseases. Several studies demonstrated that circRNAs (e.g., circACTA2, Circ-SATB2, circDiaph3, circ_0020397, circTET3, circCCDC66) played critical roles in the regulation of VSMC proliferation, migration, invasion, and contractile-to-synthetic phenotype transformation by sponging microRNAs (e.g., miR-548f-5p, miR-939, miR-148a-5p, miR-138, miR-351-5p, miR-342-3p). This review describes recent progress in the profiling of circRNAs by transcriptome analysis in VSMCs and their molecular functions in regulating VSMC proliferation and migration.

Abstract
Abdominal aortic aneurysm (AAA) is a life-threatening disorder and, therefore, investigation into its underlying mechanisms in light of the competing endogenous RNAs (ceRNAs) hypothesis has gradually increased. However, there is still lacking systematic analysis on AAA-associated circular RNA (circRNA)-microRNA (miRNA/miR)-messenger RNA (mRNA) interaction networks based on bioinformatics methods. The present study attempted to identify novel molecular biomarkers for AAA by profiling circRNA-miRNA-mRNA networks using three public microarray datasets (GSE7084, GSE57691 and GSE144431). A total of 135 differentially expressed genes (DEGs) and 142 differentially expressed circRNAs were detected using the limma R package with the statistical threshold of P<0.05 and |log2fold change (FC)| >1.5. In addition, 12 circRNA-miRNA-mRNA axes were identified to construct upregulated and downregulated ceRNA networks using Cytoscape. Based on molecular complex detection algorithm, (hsa_circ_0057691/0092108/0006845/0082182)- miR-330-5p-calponin 1 (CNN1) and (hsa_circ_0061482/0011450/0008351/0004121)-miR-326-CD8a molecule (CD8A) were recognized as the center axes in ceRNA networks. Reverse transcription-quantitative PCR results verified the significant downregulation of CNN1 and upregulation of CD8A in human AAA tissues (P<0.05). In addition, four upregulated circRNA/mRNA axes, and five downregulated circRNA/mRNA axes were revealed to have possible biological functions in the pathogenesis of AAA using the Cytoscape software. Receiver operating characteristic analysis demonstrated the accuracy of these nine DEGs involved in these axes for AAA diagnosis with area under the curves >0.80. The present study revealed novel circRNA-miRNA-mRNA networks associated with AAA, especially for CNN1 and CD8A axes with the potential function of ‘focal adhesion’ and ‘immune response’, respectively. Overall, the present findings may provide evidence to explore the implicated ceRNAs in the molecular mechanisms and as novel biomarkers for AAA.

Abstract
With the rapid development of sequencing technologies, the characteristics and functions of circular RNAs (circRNAs) in different tissues, and their underlying pathophysiological mechanisms, have been identified. circRNAs are significantly enriched in the brain and are continually expressed from the embryonic stage to the adult stage in rats. Previous studies have reported that certain circRNAs are differentially expressed in glioma and regulate a number of biological processes, such as cell proliferation, metastasis and oncogenesis of glioma. Furthermore, certain circRNAs have been associated with tumor size, World Health Organization tumor grade and poor prognosis in patients with glioma. It has been hypothesized that circRNAs may be involved in the onset and progression of glioma through transcriptional regulation, protein translation and binding to microRNAs. These properties and functions suggest the potential of circRNAs as prognostic biomarkers and therapeutic targets for glioma. For the present review, published studies were examined from PubMed, Embase, Cochrane Central and the reference lists of the retrieved articles. The aim of the present review was to summarize the progress of circRNA research in glioma, discuss the potential diagnostic and prognostic values, and the roles of circRNAs in glioma, and provide a novel theoretical basis and research concepts for the prediction, diagnosis and treatment of glioma.

[PMID: 33380803 PMCID: PMC7767728 DOI: 10.2147/ott.s281095] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 11/20/2020] [Indexed: 12/14/2022] Open
Abstract
Purpose Non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer cases and remains the primary cause of cancer-related deaths worldwide. Fentanyl is a commonly utilized anesthetic during the process of tumor resection, and exhibits inhibitory effects on the progression of numerous cancer types, including pancreatic cancer, colorectal cancer and gastric cancer. However, the effects of fentanyl on the cell viability and invasion of NSCLC has not been investigated. Current study aimed to investigate the effects and the mechanisms underlying the effects of fentanyl on NSCLC. Methods The expression of μ-opioid receptor (MOR) was proved by flow cytometry. The expression of microRNA-331-3p (miR-331-3p) and histone deacetylase 5 (HDAC5) in NSCLC tissues and cell lines are evaluated by reverse transcription-quantitative PCR (RT-qPCR) and Western blot, respectively. Cell viability and invasion are measured by cell counting kit-8 (CCK-8) assay and transwell assay, respectively. The interaction between miR-331-3p and 3ʹ-untranslated region (UTR) of HDAC5 is predicted by TargetScan 7.1 (http://www.targetscan.org/vert_71/), validated by dual luciferase assay, RT-qPCR and Western blot. Results There was lower miR-331-3p expression and higher HDAC5 expression in NSCLC cell lines A549 and CALU-1 compared with BEAS-2B, which was reversed by fentanyl administration. miR-331-3p targeted 3ʹ-UTR of HDAC5 in NSCLC cell lines A549 and CALU-1. miR-331-3p inhibitor partially abrogated the inhibitory effects of fentanyl on NSCLC cell viability and invasion by targeting HDAC5. In addition, there was higher HDAC5 expression and lower miR-331-3p expression in tumor tissues which were isolated from patients with NSCLC compared to the adjacent normal tissues, and miR-331-3p was negatively correlated with HDAC5 in NSCLC tumor tissues. Conclusion Fentanyl inhibits the viability and invasion of NSCLC cells by induction of miR-331-3p and reduction of HDAC5.
