[PMID: 38750783 DOI: 10.1016/j.exer.2024.109929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 04/18/2024] [Accepted: 05/12/2024] [Indexed: 06/02/2024]
Abstract
Optic nerve injuries are severely disrupt the structural and functional integrity of the retina, often leading to visual impairment or blindness. Despite the profound impact of these injuries, the molecular mechanisms involved remain poorly understood. In this study, we performed a comprehensive whole-transcriptome analysis of mouse retina samples after optic nerve crush (ONC) to elucidate changes in gene expression and regulatory networks. Transcriptome analysis revealed a variety of molecular alterations, including 256 mRNAs, 530 lncRNAs, and 37 miRNAs, associated with metabolic, inflammatory, signaling, and biosynthetic pathways in the injured retina. The integrated analysis of co-expression and protein-protein interactions identified an active interconnected module comprising 5 co-expressed proteins (Fga, Serpina1a, Hpd, Slc38a4, and Ahsg) associated with the complement and coagulation cascades. Finally, 5 mRNAs (Fga, Serpinala, Hpd, Slc38a4, and Ahsg), 2 miRNAs (miR-671-5p and miR-3057-5p), and 6 lncRNAs (MSTRG. 1830.1, Gm10814, A530013C23Rik, Gm40634, MSTRG.9514.1, A330023F24Rik) were identified by qPCR in the injured retina, and some of them were validated as critical components of a ceRNA network active in 661W and HEK293T cells through dual-luciferase reporter assays. In conclusion, our study provides comprehensive insight into the complex and dynamic biological mechanisms involved in retinal injury responses and highlights promising potential targets to enhance neuroprotection and restore vision.

[PMID: 38727958 DOI: 10.1007/s11033-024-09510-9] [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: 01/18/2024] [Accepted: 04/02/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND MicroRNAs are differentially expressed in periodontitis tissues. They are involved in cellular responses to inflammation and can be used as markers for diagnosing periodontitis. Microarray analysis showed that the expression level of microRNA-671-5p in periodontal tissues of patients with periodontitis was increased. In this study, we investigated the mechanism of action of microRNA-671-5p in human periodontal ligament stem cells (hPDLSCs) under inflammatory conditions. METHODS AND RESULTS HPDLSCs were treated with lipopolysaccharide (LPS) to establish an inflammation model. The cell survival rate was determined using the cell counting kit-8 (CCK8). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blot analyses were used to detect the expression of microRNA-671-5p and dual-specificity phosphatase (DUSP) 8 proteins, respectively, Interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were detected using qRT-PCR and Enzyme-linked immunosorbent assay (ELISA). A dual-luciferase reporter system was employed to determine the relationship between micoRNA-671-5p and DUSP8 expression. Activation of the p38 mitogen-activated protein kinase (MAPK) signaling pathway was confirmed using western blot analysis. Following the treatment of hPDLSCs with LPS, the expression levels of microRNA-671-5p in hPDLSCs were increased, cell viability decreased, and the expression of inflammatory factors displayed an increasing trend. MicroRNA-671-5p targets and binds to DUSP8. Silencing microRNA-671-5p or overexpressing DUSP8 can improve cell survival rate and reduce inflammatory responses. When DUSP8 was overexpressed, the expression of p-p38 was reduced. CONCLUSIONS microRNA-671-5p targets DUSP8/p38 MAPK pathway to regulate LPS-induced proliferation and inflammation in hPDLSCs.

[PMID: 36039693 DOI: 10.1080/00207454.2022.2118598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/27/2022] [Accepted: 08/22/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND The regulatory potency of circular RNA (circRNA) has been acknowledged in multiple human diseases, including ischaemic stroke (IS). However, only a few circRNAs were investigated in this disorder. We aimed to uncover the role of circ_0001360 in cell models of IS in vitro. METHODS SK-N-SH cells were subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) to simulate IS pathology conditions in vitro. Quantitative real-time PCR (qPCR) and western blot were applied for expression detection. Cell viability, proliferation and apoptosis were investigated by CCK-8, EdU and flow cytometry assays. The predicted binding of miR-671-5p to circ_0001360 or BMF 3'UTR was validated by dual-luciferase reporter and RIP assays. Proteins on the NF-κB pathway were quantified by western blot to assess NF-κB pathway activity. RESULTS Circ_0001360 was upregulated in SK-N-SH cells after OGD/R treatment. OGD/R provoked SK-N-SH cell growth impairment, apoptosis and inflammation, while circ_0001360 knockdown relieved these injuries. Circ_0001360 targeted miR-671-5p, and miR-671-5p deficiency recovered SK-N-SH cell injury that was repressed by circ_0001360 knockdown. MiR-671-5p directly combined with BMF and repressed BMF expression. Accordingly, circ_0001360 targeted miR-671-5p to regulate the expression of BMF. Circ_0001360 knockdown weakened the phosphorylated levels of P65 and IκBα, while further miR-671-5p deficiency or BMF overexpression restored their expression levels. CONCLUSION Circ_0001360 contributed to OGD/R-caused SK-N-SH cell injury via targeting the miR-671-5p/BMF network and activating the NF-κB pathway, thus participating in the development of IS.

Abstract
Neurological disorders such as stroke, multiple sclerosis, as well as the neurodegenerative diseases Parkinson's or Alzheimer's disease are accompanied or even powered by danger associated molecular patterns (DAMPs), defined as endogenous molecules released from stressed or damaged tissue. Besides protein-related DAMPs or "alarmins", numerous nucleic acid DAMPs exist in body fluids, such as cell-free nuclear and mitochondrial DNA as well as different species of extracellular RNA, collectively termed as self-extracellular nucleic acids (SENAs). Among these, microRNA, long non-coding RNAs, circular RNAs and extracellular ribosomal RNA constitute the majority of RNA-based DAMPs. Upon tissue injury, necrosis or apoptosis, such SENAs are released from neuronal, immune and other cells predominantly in association with extracellular vesicles and may be translocated to target cells where they can induce intracellular regulatory pathways in gene transcription and translation. The majority of SENA-induced signaling reactions in the brain appear to be related to neuroinflammatory processes, often causally associated with the onset or progression of the respective disease. In this review, the impact of the diverse types of SENAs on neuroinflammatory and neurodegenerative diseases will be discussed. Based on the accumulating knowledge in this field, several specific antagonistic approaches are presented that could serve as therapeutic interventions to lower the pathological outcome of the indicated brain disorders.

Abstract
Blood-brain barrier (BBB) disruption can induce further hemorrhagic transformation in ischemic stroke (IS). miR-671-5p, a micro-RNA, is abundant in the cortex of mammalian brains. Herein, we investigated the roles and potential mechanisms for the effects of miR-671-5p on BBB permeability in IS. Results showed that miR-671-5p levels were significantly downregulated in the cerebral cortex of middle cerebral artery occlusion/reperfusion (MCAO/R) C57/BL6 mice in vivo. miR-671-5p agomir administration via right intracerebroventricular injection significantly reduced infarct volume, improved neurological deficits, the axon of neurons and nerve fiber, attenuated cell injury and apoptosis, as well as reduced BBB permeability in MCAO/R mice. Treatment with miR-671-5p agomir alleviated tight junction proteins degradation, including claudin, occludin, and ZO-1 in MCAO/R mice, and these effects were reversed following NF-κB overexpression. Bend.3 brain endothelial cells were subjected to oxygen and glucose deprivation/reoxygenation (OGD/R) treatment in vivo, and then miR-671-5p agomir was transfected into the cells. This resulted in reduction of cytotoxicity, improved cell viability, trans-endothelial electrical resistance, reduced fluorescein sodium permeability, and inhibited tight junction degradation in Bend.3 OGD/R cells. However, these effects were reversed following NF-κB overexpression. These results demonstrated that upregulation of miR-671-5p in IS models in vivo and in vitro alleviated BBB permeability by targeting NF-κB/MMP-9. In summary, miR-671-5p is a potential therapeutic target for protecting BBB permeability in IS to minimize cerebral hemorrhage transformation.

Abstract
Bone metabolism consists of bone formation and resorption and maintains a dynamic balance in vivo. When bone homeostasis is broken, it can manifest as osteoarthritis (OA), rheumatoid arthritis (RA), osteosarcoma (OS), etc. MiR-671, an important class of non-coding nucleotide sequences in vivo, is regulated by lncRNA and regulates bone metabolism balance by regulating downstream target proteins and activating various signaling pathways. Based on the structure and primary function of miR-671, this paper summarizes the effect and mechanism of miR-671 in bone-related inflammation and cancer diseases, and prospects the application possibility of miR-671, providing reference information for targeted therapy of bone-related disorders.

Abstract
miR-671 is encoded by a gene on 7q36.1 and contributes to the pathogenesis of a variety of disorders, including diverse types of cancers, atherosclerosis, ischemic stroke, liver fibrosis, osteoarthritis, Parkinson's disease, rheumatoid arthritis, acute myocardial infarction and Crohn's disease. In the context of cancer, different studies have revealed opposite roles for this miRNA. In brief, it has been shown to be down-regulated in pancreatic ductal carcinoma, ovarian cancer, gastric cancer, osteosarcoma, esophageal squamous cell carcinoma and myelodysplastic syndromes. Yet, miR-671 has been up-regulated in glioma, colorectal cancer, prostate cancer and hepatocellular carcinoma. Studies in breast, lung and renal cell carcinoma have reported inconsistent results. The current review aims at summarization of the role of miR-671 in these disorders focusing on its target mRNA in each context and dysregulated signaling pathways. We also provide a summary of the role of this miRNA as a prognostic factor in malignancies.

A systematic review of the research progress of non-coding RNA in neuroinflammation and immune regulation in cerebral infarction/ischemia-reperfusion injury. Front Immunol 2022; 13:930171. [PMID: 36275741 PMCID: PMC9585453 DOI: 10.3389/fimmu.2022.930171] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 08/08/2022] [Indexed: 11/15/2022] Open
Abstract
Cerebral infarction/ischemia-reperfusion injury is currently the disease with the highest mortality and disability rate of cardiovascular disease. Current studies have shown that nerve cells die of ischemia several hours after ischemic stroke, which activates the innate immune response in the brain, promotes the production of neurotoxic substances such as inflammatory cytokines, chemokines, reactive oxygen species and − nitrogen oxide, and mediates the destruction of blood-brain barrier and the occurrence of a series of inflammatory cascade reactions. Meanwhile, the expression of adhesion molecules in cerebral vascular endothelial cells increased, and immune inflammatory cells such as polymorphonuclear neutrophils, lymphocytes and mononuclear macrophages passed through vascular endothelial cells and entered the brain tissue. These cells recognize antigens exposed by the central nervous system in the brain, activate adaptive immune responses, and further mediate secondary neuronal damage, aggravating neurological deficits. In order to reduce the above-mentioned damage, the body induces peripheral immunosuppressive responses through negative feedback, which increases the incidence of post-stroke infection. This process is accompanied by changes in the immune status of the ischemic brain tissue in local and systemic systems. A growing number of studies implicate noncoding RNAs (ncRNAs) as novel epigenetic regulatory elements in the dysfunction of various cell subsets in the neurovascular unit after cerebral infarction/ischemia-reperfusion injury. In particular, recent studies have revealed advances in ncRNA biology that greatly expand the understanding of epigenetic regulation of immune responses and inflammation after cerebral infarction/ischemia-reperfusion injury. Identification of aberrant expression patterns and associated biological effects of ncRNAs in patients revealed their potential as novel biomarkers and therapeutic targets for cerebral infarction/ischemia-reperfusion injury. Therefore, this review systematically presents recent studies on the involvement of ncRNAs in cerebral infarction/ischemia-reperfusion injury and neuroimmune inflammatory cascades, and elucidates the functions and mechanisms of cerebral infarction/ischemia-reperfusion-related ncRNAs, providing new opportunities for the discovery of disease biomarkers and targeted therapy. Furthermore, this review introduces clustered regularly interspaced short palindromic repeats (CRISPR)-Display as a possible transformative tool for studying lncRNAs. In the future, ncRNA is expected to be used as a target for diagnosing cerebral infarction/ischemia-reperfusion injury, judging its prognosis and treatment, thereby significantly improving the prognosis of patients.

Abstract
The competing endogenous RNA (ceRNA) activity of long non-coding RNAs (lncRNAs) has profound effects in pathological disorders, including Parkinson's disease. Here, we focused on the LINC00943-mediated ceRNA network for the regulation of LINC00943 in MPP+ toxicity in SK-N-SH cells. SK-N-SH cells were exposed to 1-methyl-4-phenylpyridinium (MPP+). LINC00943, miR-671-5p and ELAV like RNA binding protein 1 (ELAVL1) were quantified by real-time quantitative PCR (RT-qPCR) or western blot. Cell viability and apoptosis were gauged by Cell Counting Kit-8 (CCK-8) assay and flow cytometry, respectively. Direct relationship between miR-671-5p and LINC00943 or ELAVL1 was confirmed by dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. Our data validated that LINC00943 regulated MPP+-evoked injury in SK-N-SH cells. LINC00943 regulated miR-671-5p expression by binding to miR-671-5p. Moreover, miR-671-5p was identified as a molecular mediator of LINC00943 in regulating SK-N-SH cell injury induced by MPP+. MiR-671-5p targeted and inhibited ELAVL1, and miR-671-5p-mediated inhibition of ELAVL1 impacted MPP+-evoked SK-N-SH cell injury. Furthermore, LINC00943 involved the post-transcriptional regulation of ELAVL1 through miR-671-5p competition. Our present study has established a novel mechanism, the LINC00943/miR-671-5p/ELAVL1 ceRNA crosstalk, for the regulation of LINC00943 on MPP+ toxicity in SK-N-SH cells.

Long Non-coding RNA ANRIL Downregulation Alleviates Neuroinflammation in an Ischemia Stroke Model via Modulation of the miR-671-5p/NF-κB Pathway. Neurochem Res 2022; 47:2002-2015. [PMID: 35359242 DOI: 10.1007/s11064-022-03585-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 02/17/2022] [Accepted: 03/17/2022] [Indexed: 10/18/2022]
Abstract
The aim of this study was to investigate the role and underlying mechanism of the long non-coding RNA ANRIL (antisense noncoding RNA in the INK4 locus, ANRIL) in ischemia stroke (IS) injury. Downregulation of ANRIL by right intracerebroventricular injected si-ANRIL in middle cerebral artery occlusion-reperfusion (MCAO/R) C57/BL6 mice and by transferring si-ANRIL in oxygen glucose deprivation/reperfusion (OGD/R) HT22 cells. The results showed that ANRIL levels increased in IS model, downregulation of ANRIL reduced infract area, neurological deficit scores and injured cells, and prolong fall latency time in MCAO/R mice, improved cell viability and reduced cell cytotoxicity in OGD/R cells. Fluorescence in Situ Hybridization detected that there were both ANRIL and miR-671-5p in neurons; miranda v3.3a and dual luciferase reporter assay demonstrated that miR-671-5p was one of direct target of ANRIL; and our previously published research demonstrated that NF-κB was one of direct target of miR-671-5p. Downregulation of ANRIL alleviated neuroinflammation and reduced p-NF-κB, NF-κB, pro-inflammatory cytokines (IL-1β, IL-6, TNF-a), and iNOS, which diminished by miR-671-5p antagomir both in in vivo and in vitro IS models. Downregulation of ANRIL alleviated disruption of blood brain barrier, and protected against tight junction (ZO-1, occludin and claudin 5) disorder in MCAO/R mice. This work clarified that downregulation of ANRIL reduced neuroinflammation by negatively regulating miR-671-5p to inhibit NF-κB in IS models, which provided a theoretical foundation for the protective effect of downregulating ANRIL for IS patients.

Circ_0001947 promotes cell proliferation, invasion, migration and inflammation and inhibits apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes through miR-671-5p/STAT3 axis. J Orthop Surg Res 2022; 17:54. [PMID: 35093109 PMCID: PMC8800221 DOI: 10.1186/s13018-022-02939-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 01/13/2022] [Indexed: 12/14/2022] Open
Abstract
Background Circular RNAs (circRNAs) have emerged as vital regulators in the development of rheumatoid arthritis (RA). In this study, we aimed to explore the functions and mechanisms of circ_0001947 in RA. Methods The expression of circ_0001947, microRNA-671-5p (miR-671-5p) and signal transducer and activator of transcription 3 (STAT3) was determined by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. Cell Counting Kit-8 (CCK-8) assay, 5′-ethynyl-2′-deoxyuridine (EdU) assay, flow cytometry analysis, transwell assay and wound-healing assay were performed to assess cell proliferation, apoptosis, invasion and migration. The concentrations of inflammatory factors were examined with enzyme-linked immunosorbent assay (ELISA) kits. Dual-luciferase reporter assay was used to analyze the relationships of circ_0001947, miR-671-5p and STAT3. Results Circ_0001947 was upregulated in RA patients and RA-FLSs. Knockdown of circ_0001947 repressed cell proliferation, invasion, migration and inflammatory response and facilitated apoptosis in RA-FLSs. Circ_0001947 served as the sponge for miR-671-5p and the inhibitory effect of circ_0001947 in RA-FLS progression was reversed by miR-671-5p inhibition. STAT3 was the target gene of miR-671-5p. MiR-671-5p overexpression restrained RA-FLS growth, invasion, migration and inflammation and promoted apoptosis, but STAT3 upregulation reversed the impacts. Conclusion Circ_0001947 contributed to the progression of RA-FLSs by elevating STAT3 through adsorbing miR-671-5p. Circ_0001947 is abnormally upregulated in RA synovial tissues and RA-FLSs. Circ_0001947 silencing inhibits cell proliferation, invasion, migration and inflammatory response and induces apoptosis in RA-FLSs. Circ_0001947 sponges miR-671-5p, which directly interacts with STAT3. Circ_0001947 regulates RA-FLS progression via miR-671-5p/STAT3 axis.
