[PMID: 38726183 PMCID: PMC11079323 DOI: 10.1016/j.heliyon.2024.e30555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 04/26/2024] [Accepted: 04/29/2024] [Indexed: 05/12/2024] Open
Abstract
Background Rheumatoid arthritis (RA) is a chronic inflammatory disease that leads to progressive joint damage. Circular RNA (circRNA) can regulate the inflammatory response of fibroblast-like synoviocytes (FLSs) in RA, influencing the disease progression. Paeoniflorin (PF) is the main active ingredient extracted from Paeonia lactiflora and is known for its anti-inflammatory effect. This study aims to explore the potential mechanisms by which hsa_circ_009012 and PF regulate the inflammatory response in RA. Methods RNA expression of hsa_circ_009012, has-microRNA-1286 (miR-1286), toll-like receptor 4 (TLR4), NOD-like receptor thermal protein domain associated protein 3 (NLRP3) was assessed by real-time quantitative polymerase chain reaction (RT-qPCR) or western blotting (WB). Cell inflammation markers (TNF-α, IL-1β, IL-6) were assessed by RT-qPCR and immunofluorescence (IF). Counting Kit-8 (CCK-8) assay, flow cytometry, and transwell assay were utilized to test cell viability, cell cycle distribution, and migration. Results Hsa_circ_009012 was highly expressed in RA-FLS. Hsa_circ_009012 over-expression facilitated the inflammation in RA-FLS and was closely associated with the miR-1286/TLR4 axis. Paeoniflorin inhibited inflammation and the expression of hsa_circ_009012 and TLR4, while upregulating the expression of miR-1286 in RA-FLS. Moreover, the upregulation of hsa_circ_009012 reversed the repressive effect of paeoniflorin on RA-FLS progression. Conclusion Paeoniflorin inhibits the inflammation of RA-FLS via mediating the hsa_circ_009012/miR-1286/TLR4/NLRP3 axis.

Abstract
Long noncoding RNAs (lncRNAs) play important roles in numerous biological processes, including the immune system. Initial research in this area focused on cell-based studies, but recent advances underscore the profound significance of lncRNAs at the organismal level, providing invaluable insights into their roles in inflammatory diseases. In this rapidly evolving field, lncRNAs have been described with pivotal roles in the intestinal tract where they regulate intestinal homeostasis and inflammation by influencing processes such as immune cell development, inflammatory signaling pathways, epithelial barrier function, and cellular metabolism. Understanding the regulation and function of lncRNAs in this tissue may position lncRNAs not only as potential disease biomarkers but also as promising targets for therapeutic intervention in inflammatory bowel disease and related diseases.

Clin Rheumatol 2024; 43:147-157.

Abstract
PURPOSE SYVN1 is an endoplasmic reticulum (ER)-resident E3 ubiquitin ligase that has an essential function along with SEL1L in rheumatoid arthritis (RA) pathogenesis. This study aimed to investigate the changes in the expression of peripheral blood ncRNAs and SYVN1-SEL1L affected by DMARDs treatment. METHODS Twenty-five newly diagnosed RA patients were randomly assigned to receive conventional DMARDs (csDMARDs) and methylprednisolone for six months. The peripheral blood gene expression of SYVN1 and SEL1L and possible regulatory axes, NEAT1, miR-125a-5p, and miR-19b-3p, were evaluated before and after qRT-PCR. We also compared differences between the patients and healthy controls (HCs), and statistical analyses were performed to determine the correlation between ncRNAs with SYVN1-SEL1L and the clinical parameters of RA. RESULTS Expression of NEAT1 (P = 0.0001), miR-19b-3p (P = 0.007), miR-125a-5p (P = 0.005), and SYVN1 (P = 0.036) was significantly increased in newly diagnosed patients compared to HCs; also, miR-125a-5p, miR-19b-3p, and SYVN1 were significantly overexpressed after treatment (P = 0.001, P = 0.001, and P = 0.005, respectively). NEAT1 was positively correlated with SYVN1, and miR-125a-5p had a negative correlation with anti-cyclic citrullinated peptides. The ROC curve analysis showed the potential role of selected ncRNAs in RA pathogenesis. CONCLUSION The results indicate the ineffectiveness of the csDMARDs in reducing SYVN1 expression. The difference in expression of ncRNAs might be useful markers for monitoring disease activity and determining therapeutic responses in RA patients. Key Points • The expression of NEAT1 is significantly upregulated in RA patients compared to HC subjects. • miR-19b-3p, miR-125a-5p, and SYVN1 are significantly upregulated in RA patients compared to HC subjects. • The expression of miR-19b-3p and miR-125a-5p is significantly increased in RA patients after treatment with DMARDs and methylprednisolone. • NEAT1 is positively correlated with SYVN1.

[PMID: 38203588 PMCID: PMC10779327 DOI: 10.3390/ijms25010417] [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: 11/20/2023] [Revised: 12/22/2023] [Accepted: 12/26/2023] [Indexed: 01/12/2024] Open
Abstract
Circular RNAs (circRNAs) are noncoding molecules and are generated through back splicing, during which the 5' and 3' ends are covalently joined. Consequently, the lack of free ends makes them stable and resistant to exonucleases, and they become more suitable biomarkers than other noncoding RNAs. The aim of the study was to find an association between selected circRNAs and disease activity in patients with RA. A total of 71 subjects, 45 patients with RA and 26 healthy controls (HCs), were enrolled. In the RA group, 24 patients had high disease activity (DAS-28-ESR > 5.1) and 21 individuals were in remission (DAS-28-ESR ≤ 2.6). The cell line SW982 was used to evaluate the biological function of circ_0005567. The concentration of circ_0005567 in RA patients was elevated compared to HCs (median, 177.5 [lower-upper quartile, 83.13-234.6] vs. 97.83 [42.03-145.4], p = 0.017). Patients with high disease activity had a higher concentration of circ_0005567 than the control group (185.4 [112.72-249.25] vs. 97.83 [42.03-145.4], p = 0.015). In the cell line model, we found an association between circ_0005567 and miR-194-5p concentration and increased expression of mRNAs that may be related to cell proliferation. The plasma concentration of circ_0005567 may be a new potential biomarker associated with disease activity in patients with RA.

Efficient delivery of the lncRNA LEF1-AS1 through the antibody LAIR-1 (CD305)-modified Zn-Adenine targets articular inflammation to enhance the treatment of rheumatoid arthritis. Arthritis Res Ther 2023; 25:238. [PMID: 38062469 PMCID: PMC10702009 DOI: 10.1186/s13075-023-03226-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 11/29/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUNDS Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease characterized by synovial hyperplasia. Maintaining a balance between the proliferation and apoptosis of rheumatoid arthritis synovial fibroblasts (RASFs) is crucial for preventing the erosion of bone and cartilage and, ultimately, mitigating the progression of RA. We found that the lncRNA LEF1-AS1 was expressed at low levels in the RASFs and inhibited their abnormal proliferation by targeting PIK3R2 protein and regulating the PI3K/AKT signal pathway through its interaction with miR-30-5p. In this study, we fabricated a nano-drug delivery system for LEF1-AS1 using Zn-Adenine nanoparticles (NPs) as a novel therapeutic strategy against RA. METHODS The expression levels of LEF1-AS1, miR-30-5p, PIK3R2, p-PI3K, and p-AKT were detected in the primary RASFs and a human fibroblast-like synovial cell line (HFLS). Zn-Adenine nanoparticles (NPs) were functionalized with anti-CD305 antibody to construct (Zn-Adenine)@Ab. These NPs were then loaded with LEF1-AS1 to form (Zn-Adenine)@Ab@lncRNA LEF1-AS1. Finally, the (Zn-Adenine)@Ab@lncRNA LEF1-AS1 NPs were locally injected into a rat model with collagen-induced arthritis (CIA). The arthritic injuries in each group were evaluated by HE staining and other methods. RESULTS LEF1-AS1 was expressed at low levels in the primary RASFs. High expression levels of LEF1-AS1 were detected in the HFLS cells, which corresponded to a significant downregulation of miR-30-5p. In addition, the expression level of PIK3R2 was significantly increased, and that of p-PI3K and p-AKT were significantly downregulated in these cells. The (Zn-Adenine)@Ab@lncRNA LEF1-AS1 NPs significantly inhibited the proliferation of RASFs and decreased the production of inflammatory cytokines (IL-1β, IL-6, TNF-α). Intra-articular injection (IAI) of (Zn-Adenine)@Ab@lncRNA LEF1-AS1 NPs significantly alleviated cartilage destruction and joint injury in the CIA-modeled rats. CONCLUSIONS LEF1-AS1 interacts with miR-30-5p to inhibit the abnormal proliferation of RASFs by regulating the PI3K/AKT signal pathway. The (Zn-Adenine)@Ab NPs achieved targeted delivery of the loaded LEF1-AS1 into the RASFs, which improved the cellular internalization rate and therapeutic effects. Thus, LEF1-AS1 is a potential target for the treatment of RA.

Comprehensive analysis of serum exosome-derived lncRNAs and mRNAs from patients with rheumatoid arthritis. Arthritis Res Ther 2023; 25:201. [PMID: 37845777 PMCID: PMC10577909 DOI: 10.1186/s13075-023-03174-9] [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: 02/22/2023] [Accepted: 09/15/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Serum exosomes play important roles in intercellular communication and are promising biomarkers of several autoimmune diseases. However, the biological functions and potential clinical importance of long non-coding RNAs (lncRNAs) and mRNAs from serum exosomes in rheumatoid arthritis (RA) have not yet been studied. METHODS Serum exosomal lncRNAs and mRNAs were isolated from patients with RA and osteoarthritis (OA) and healthy controls. The differentially expressed lncRNAs (DE-lncRNAs) and mRNA profiles in the serum exosomes of patients with RA were analysed using high-throughput sequencing, and their functions were predicted using Gene Ontologyenrichment, Kyoto Encyclopedia of Genes and Genomes pathway, and gene set enrichment analysis. We constructed a DE-lncRNA-mRNA network and a protein-protein interaction network of differentially expressed mRNAs (DE-mRNAs) in RA using the Cytoscape software. The expression of several candidate a DE-lncRNAs and DE-mRNAs in the serum of patients with RA, patients with OA, and healthy controls was confirmed by qRT-PCR. We assessed the diagnostic ability of DE-lncRNAs and DE-mRNAs in patients with RA using receiver operating characteristic analysis. Furthermore, we analysed the characteristics of immune cell infiltration in RA by digital cytometry using the CIBERSORT algorithm and determined the correlation between immune cells and several DE-lncRNAs or DE-mRNAs in RA. RESULTS The profiles of serum exosomal lncRNAs and mRNAs in patients with RA were different from those in healthy controls and patients with OA. The functions of both DE-lncRNAs and DE-mRNAs in RA are associated with the immune response and cellular metabolic processes. The RT-PCR results show that NONHSAT193357.1, CCL5, and MPIG6B were downregulated in patients with RA. The combination of three DE-mRNAs, CCL5, MPIG6B, and PFKP, had an area under the curve of 0.845 for differentiating RA from OA. Digital cytometry using the CIBERSORT algorithm showed that the neutrophil counts were higher in patients with RA than those in healthy controls and patients with OA. CONCLUSIONS These findings help to elucidate the role of serum exosomal lncRNAs and mRNAs in the specific mechanisms underlying RA.

Abstract
Circular RNAs have been demonstrated to play a critical role in the progression of autoimmune diseases. This study aimed to investigate the function of circ_0000479 in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs). Circ_0000479 was found to be upregulated in RA-FLSs. Flow cytometry analysis, cell counting Kit-8, transwell, wound-healing and enzyme-linked immunosorbent assays were conducted to evaluate RA-FLS apoptosis, proliferation, invasion, migration and inflammation. The results confirmed that circ_0000479 knockdown suppressed pathogenic properties of RA-FLSs. Through bioinformatics analysis and screening, we obtained 18 miRNAs that can bind to circ_0000479, of which miR-766 was most significantly up-regulated after circ_0000479 knockdown. MiR-766 was confirmed to be down-regulated in RA-FLSs and the combination between circ_0000479 and miR-766 was verified by dual-luciferase reporter assays. Moreover, the inhibitory effect of circ_0000479 knockdown in RA-FLS progression was attenuated by miR-766 inhibitor. By intersecting the target genes of miR-766 with the up-regulated genes in RA, we obtained 8 genes, of which FKBP5 was most significantly down-regulated after miR-766 overexpression. The results of dual-luciferase reporter assays also verified that FKBP5 was the target gene of miR-766. In addition, FKBP5 overexpression abated the inhibition of RA-FLS progression caused by circ_0000479 silencing. In summary, circ_0000479 binds to miR-766 to promote RA progression via FKBP5.

Rheumatoid arthritis and non-coding RNAs; how to trigger inflammation. Life Sci 2023; 315:121367.

Abstract
Rheumatoid arthritis (RA) is a systemic and chronic inflammatory disease categorized by continuous synovitis in the joints and systemic inflammatory responses that can cause lifelong disability. The major cause of RA is the dysregulation of the immune response. The development of RA disease includes multiplex association of several interleukins and cells, which leads to synovial cell growth, cartilage and bone damage. The primary stage of RA disease is related to the modification of both the innate and adaptive immune systems, which leads to the formation of autoantibodies. This process results in many damaged molecules and epitope spreading. Both the innate (e.g., dendritic cells, macrophages, and neutrophils) and acquired immune cells (e.g., T and B lymphocytes) will increase and continue the chronic inflammatory condition in the next stages of the RA disease. In recent years, non-coding RNAs have been proved as significant controllers of biological functions, especially immune cell expansion and reactions. Non-coding RNAs were primarily containing microRNA (miRNA), long non-coding RNA (lncRNA), and circular RNA (circRNA). Various studies confirmed non-coding RNAs as hopeful markers for diagnosing and curing RA. This review will describe and cover existing knowledge about RA pathogenesis, which might be favorable for discovering possible ncRNA markers for RA.

Abstract
The dysregulation of microRNAs plays a critical role in the development of rheumatoid arthritis (RA). This study aims to explore the functional significance of miR-326 in RA. The RT-qPCR results showed that miR-326 was downregulated in synovial tissues of RA patients and RA fibroblast-like synoviocytes (RA-FLS). We found that miR-326 could target and reduce the expression of inhibitor of DNA binding 1 (Id1). MTT assay and flow cytometry were conducted to explore the biological function of miR-326. Our data revealed that the upregulation of miR-326 suppressed cell proliferation and induced apoptosis in RA-FLS. In collagen-induced arthritis mice, intraarticular injection of lentivirus carrying miR-326 overexpression vectors could reduce the arthritis score and attenuate synovial inflammation and cartilage destruction. We also found that long non-coding RNA-Ewing sarcoma-associated transcript 1 (lncRNA-EWSAT1) was significantly increased in RA synovial tissues and RA-FLS. The RNA immunoprecipitation and RNA pull-down assay indicated that lncRNA-EWSAT1 directly bound and negatively regulated the expression of miR-326. Knockdown of lncRNA-EWSAT1 could upregulate miR-326 expression and attenuate its proliferation inhibition and apoptosis induction effect in RA-FLS. In conclusion, the lncRNA-EWSAT1/miR-326 axis might provide a novel therapeutic target in the treatment of RA.

Abstract
In recent years, diagnostic and therapeutic approaches for rheumatoid arthritis (RA) have continued to improve. However, in the advanced stages of the disease, patients are unable to achieve long-term clinical remission and often suffer from systemic multi-organ damage and severe complications. Patients with RA usually have no overt clinical manifestations in the early stages, and by the time a definitive diagnosis is made, the disease is already at an advanced stage. RA is diagnosed clinically and with laboratory tests, including the blood markers C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) and the autoantibodies rheumatoid factor (RF) and anticitrullinated protein antibodies (ACPA). However, the presence of RF and ACPA autoantibodies is associated with aggravated disease, joint damage, and increased mortality, and these autoantibodies have low specificity and sensitivity. The etiology of RA is unknown, with the pathogenesis involving multiple factors and clinical heterogeneity. The early diagnosis, subtype classification, and prognosis of RA remain challenging, and studies to develop minimally invasive or non-invasive biomarkers in the form of biofluid biopsies are becoming more common. Non-coding RNA (ncRNA) molecules are composed of long non-coding RNAs, small nucleolar RNAs, microRNAs, and circular RNAs, which play an essential role in disease onset and progression and can be used in the early diagnosis and prognosis of RA. In this review of the diagnostic and prognostic approaches to RA disease, we provide an overview of the current knowledge on the subject, focusing on recent advances in mRNA-ncRNA as diagnostic and prognostic biomarkers from the biofluid to the tissue level.

Abstract
Rheumatoid arthritis (RA) is a systemic disease dominated by inflammatory synovitis. RA synovial macrophages tend undergo M1-type macrophage polarization. Then, polarized M1-type macrophages secrete abundant pro-inflammatory cytokines, causing joint and cartilage destruction. N6-methyladenosine (m6A) methylation modification, circular RNA (circRNA), microRNA (miRNA), messenger RNA (mRNA), etc. are involved in the inflammatory response of RA. We found that there is an imbalance of inflammatory polarization in RA, which is manifested by a sharp increase in inflammatory markers and a high inflammatory response. Here, we show that RA was closely associated with low expression of circ_0066715. The overexpression of circ_0066715 significantly increased the ETS1 levels in RA-FLS cells, decreased cytokine secretion by M1-type macrophages, elevated M2-type cytokines, and inhibited FLS proliferation. Interestingly, the overexpression of miR-486-5p significantly suppressed the attenuation of the cell function and the effect on M1 macrophage polarization caused by circ_0066715 positive expression. WTAP may be involved in the methylation process of ETS1 in RA. ETS1 m6A methylation levels were altered upon WTAP intervention. The overexpression or interference of circ_0066715 decreased or increased WTAP expression. Our findings provide a novel circRNA/miRNA/mRNA regulatory axis and m6A regulatory mechanism involved in the process of RA macrophage polarization, thereby providing a powerful diagnostic and therapeutic strategy for RA treatment.

Abstract
Bone is a connective tissue that has important functions in the human body. Cells and the extracellular matrix (ECM) are key components of bone and are closely related to bone-related diseases. However, the outcomes of conventional treatments for bone-related diseases are not promising, and hence it is necessary to elucidate the exact regulatory mechanisms of bone-related diseases and identify novel biomarkers for diagnosis and therapy. Circular RNAs (circRNAs) are single-stranded RNAs that form closed circular structures without a 5' cap or 3' tail and polycyclic adenylate tails. Due to their high stability, circRNAs have the potential to be typical biomarkers. Accumulating evidence suggests that circRNAs are involved in bone-related diseases, including osteoarthritis, osteoporosis, osteosarcoma, multiple myeloma, intervertebral disc degeneration, and rheumatoid arthritis. Herein, we summarize the recent research progress on the characteristics and functions of circRNAs, and highlight the regulatory mechanism of circRNAs in bone-related diseases.

Abstract
BACKGROUNDS Rheumatoid arthritis (RA) is a chronic inflammatory and autoimmune disease. Current studies suggest that long noncoding RNAs (lncRNAs) may be key regulators in pathogenesis. METHODS Analyzed lncRNAs and mRNAs using microarrays to find key differentially expressed lncRNAs in RA. GO and KEGG enrichment analysis together with coding non-coding co-expression (CNC) network was used for comprehensive analysis. Verify that their expression levels are consistent with the chip results by qRT-PCR. RESULTS There are 268 differentially expressed lncRNAs (DELs) and 286 differentially expressed mRNAs (DEMs). We found 8 core lncRNAs through the CNC network. Eight highly significantly differentially expressed lncRNAs corrected with microarray profiles. The functions and associated pathways of significantly differentially expressed lncRNAs were predicted by GO and KEGG analysis. They may be involved in the pathogenesis of RA. CONCLUSION The differential expression profiles of lncRNAs and mRNAs in the collagen-induced arthritis rat model preliminarily predicted functions through comprehensive analysis. However, its exact role and specific mechanism remain to be further studied.

Abstract
Circular RNA_0004712 (circ_0004712) is reported to be up-regulated in rheumatoid arthritis (RA) patients. Nevertheless, its role and mechanism in RA pathology remain to be clarified. RNA and protein expression was determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot assay. Cell viability, proliferation, apoptosis, migration, and inflammation were assessed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, 5-ethynyl-20-deoxyuridine assay, flow cytometry, scratch test, and enzyme-linked immunosorbent assay. The target correlation between microRNA-633 (miR-633) and circ_0004712 or TNF receptor associated factor 6 (TRAF6) was verified by dual-luciferase reporter assay and RNA immunoprecipitation assay. Circ_0004712 was up-regulated in RA synovial tissues and RA fibroblast-like synoviocytes (RA-FLSs). Circ_0004712 silencing suppressed the viability, proliferation, migration and inflammatory response and facilitated the apoptosis of RA-FLSs. miR-633 was confirmed to be a direct target of circ_0004712, and miR-633 knockdown reversed circ_0004712 silencing-mediated protective effects on the dysfunction and inflammation of RA-FLSs. TRAF6 was a direct target of miR-633, and miR-633 overexpression suppressed the aggressive changes of RA-FLSs by down-regulating TRAF6. Circ_0004712 could up-regulate TRAF6 expression by sponging miR-633 in RA-FLSs. Circ_0004712 interference inactivated nuclear factor (NF)-κB signaling by targeting miR-633/TRAF6 axis. Circ_0004712 silencing inhibited the aggressive changes of RA-FLSs by targeting miR-633/TRAF6 axis and NF-κB signaling, which provided new targets for RA therapy.

Abstract
BACKGROUND Circular RNAs (circRNAs) are demonstrated to play vital roles in human diseases, including rheumatoid arthritis (RA). Therefore, this research aimed to explore the effects of hsa_circRNA_0025908 (circ_0025908) on RA. METHODS RNA expression of circ_0025908, microRNA-650 (miR-650), and Signal peptide-CUBepidermal growth factor-like containing protein 2 (SCUBE2) were assessed by real-time quantitative polymerase chain reaction; protein expression of SCUBE2, apoptosis- and invasion-related proteins was evaluated by western blot assay. Functional assays were performed using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazol-3-ium bromide, 5-ethynyl-2'-deoxyuridine, transwell, flow cytometry, and enzyme linked immunosorbent assay assays. Dual-luciferase reporter, RNA immunoprecipitation, and RNA pull-down assays confirmed the interaction relationship among circ_0025908, miR-650, and SCUBE2. RESULTS Circ_0025908 was overexpressed in synovial tissues and fibroblast-like synoviocytes (FLS) from RA patients. Inhibition of circ_0025908 repressed proliferation, migration, invasion, inflammation, and cell cycle progression, while induced apoptosis in the FLS isolated from RA patients (FLS-RA), accompanied with increased Bax, cleaved caspase-3 and E-cadherin, but declined Bcl-2, N-cadherin and Vimentin. MiR-650 was a target of circ_0025908, and SCUBE2 was a target for miR-650. Silencing of miR-650 could overturned above effects of circ_0025908 knockdown in FLS-RA, whereas its overexpression could mimic those effects by downregulating SCUBE2. Additionally, SCUBE2 expression could be positively regulated by circ_0025908 and inversely regulated by miR-650. Notably, Pearson's correlation analysis confirmed the linear correlation among circ_0025908, miR-650 and SCUBE2 in these RA tissues. CONCLUSION Circ_0025908 inhibition can suppress FLS-RA dysfunctions through targeting miR-650/SCUBE2 axis, suggesting a new potential therapeutic clue for RA patients.

Abstract
BACKGROUND Circular RNAs (circRNAs) can play a critical role in rheumatoid arthritis (RA) pathogenesis by involving gene regulation by competing for shared microRNAs (miRNAs), a family of small noncoding RNAs. MiR-130a-3p is a disease-related miRNA and Kruppel-like factor 9 (KLF9) is a zinc finger transcription factor, which are involved in RA pathogenesis. Here, we identified the action of circRNA circ_0130438 in regulating fibroblast-like synoviocytes (FLSs) stimulated by tumor necrosis factor α (TNF-α). METHODS The direct relationship between miR-130a-3p and circRNA circ_0130438 or KLF9 was predicted by bioinformatics analysis and examined by a dual-luciferase reporter or RNA immunoprecipitation (RIP) assay. CircRNA circ_0130438, miR-130a-3p and KLF9 factor expression levels were gauged by a quantitative real-time PCR (qRT-PCR) or a western blot method. Cell proliferation ability was analyzed by a 5-Ethynyl-2'-Deoxyuridine (EdU) staining assay. The transwell assay was used to evaluate cell migration and invasion capacities. The production levels of interleukin-1β (IL)-1β, IL-6 and IL-8 were assessed by enzyme-linked immunosorbent assay (ELISA). RESULTS The level of circRNA circ_0130438 was reduced in RA tissues (P = 0.0001) and FLSs isolated from RA tissues (P = 0.0001) compared with corresponding normal controls. Exposure of human fibroblast-like MH7A synoviocytes to TNF-α suppressed circRNA circ_0130438 expression (P < 0.0001). In contrast, the elevated expression of circRNA circ_0130438 suppressed the TNF-α-induced proliferation (P = 0.0047) and migration (P = 0.0023) of MH7A cells, as well as their pro-inflammatory cytokines (IL-1β, IL-6 and IL-8) production (P < 0.0001, P < 0.0001 and P < 0.0001). The circRNA circ_0130438 contained a miR-130a-3p binding site. Furthermore, the increase of miR-130-3p in TNF-α-stimulated MH7A cells reversed the effects of circRNA circ_0130438 elevation on cell proliferation (P = 0.0006), migration (P = 0.0406) and pro-inflammatory cytokines (IL-1β, IL-6 and IL-8) production (P = 0.0036, P < 0.0001 and P = 0.0004), indicating that miR-130a-3p was a functional mediator of circRNA circ_0130438 regulation. We also documented that KLF9 was a direct target and downstream effector of miR-130a-3p. Importantly, circRNA circ_0130438 enhanced KLF9 expression (P < 0.0001) in TNF-α-stimulated MH7A cells by functioning as a competing endogenous RNA (ceRNA) for miR-130a-3p (P = 0.0004). CONCLUSION Our findings demonstrate that the elevated expression of circRNA circ_0130438 suppresses TNF-α-induced migration, proliferation and pro-inflammatory cytokines (IL-1β, IL-6 and IL-8) production of human MH7A cells by enhancing KLF9 expression by operating as a ceRNA for miR-130a-3p.

Abstract
Rheumatoid arthritis (RA) is one of the most common autoimmune diseases that affect synovitis, bone, cartilage, and joint. RA leads to bone and cartilage damage and extra-articular disorders. However, the pathogenesis of RA is still unclear, and the lack of effective early diagnosis and treatment causes severe disability, and ultimately, early death. Accumulating evidence revealed that the regulatory network that includes long non-coding RNAs (lncRNAs)/circular RNAs (circRNAs), micro RNAs (miRNAs), and messenger RNAs (mRNA) plays important roles in regulating the pathological and physiological processes in RA. lncRNAs/circRNAs act as the miRNA sponge and competitively bind to miRNA to regulate the expression mRNA in synovial tissue, FLS, and PBMC, participate in the regulation of proliferation, apoptosis, invasion, and inflammatory response. Thereby providing new strategies for its diagnosis and treatment. In this review, we comprehensively summarized the regulatory mechanisms of lncRNA/circRNA-miRNA-mRNA network and the potential roles of non-coding RNAs as biomarkers and therapeutic targets for the diagnosis and treatment of RA.

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.

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.

Long non-coding RNA RP11-342L8.2, derived from RNA sequencing and validated via RT-qPCR, is upregulated and correlates with disease severity in psoriasis patients. Ir J Med Sci 2022; 191:2643-2649. [PMID: 35028895 DOI: 10.1007/s11845-021-02882-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Accepted: 12/01/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVE This study aimed to explore the dysregulated long non-coding RNA (lncRNA) expression profile in psoriatic tissue vs. normal skin tissue via RNA sequencing (RNA-seq), then further sort candidate lncRNAs to be validated by reverse transcription quantitative polymerase chain reaction (RT-qPCR), in order to investigate the comprehensive linkage of lncRNA with psoriasis. METHODS Twenty-five psoriasis patients were consecutively enrolled, with their psoriatic and surrounding normal skin tissues obtained. Ten pairs of psoriatic and normal tissues were proposed to RNA-seq. Then, top 6 differentially expressed lncRNAs (DElncRNA) were sorted as candidate lncRNAs for validation by RT-qPCR in 25 pairs of samples. RESULTS Principal component analysis (PCA) exhibited that lncRNA profile clearly distinguished psoriatic tissue from normal tissue, so did heatmap. Volcano plot disclosed 412 upregulated and 625 downregulated DElncRNAs in psoriatic tissue vs. normal tissue. Gene Ontology (GO) and Kyoko Encyclopedia of Genes and Genomes (KEGG) enrichment analyses exhibited that these DElncRNAs were mainly enriched in immune, inflammation, or proliferation-related biological processes and pathways such as neutrophil degranulation, regulation of immune response, positive regulation of cell proliferation, and MAPK signaling pathway. By RT-qPCR validation, lncRNAs RP11-22A3.2, RP11-342L8.2, and CTD-2006H14.2 were increased (all P < 0.001), while lncRNAs AP000442.4, CCDC144NL-AS1, and MIR663AHG were decreased (all P < 0.01) in psoriatic tissue vs. normal tissue. Interestingly, psoriatic lncRNA RP11-342L8.2 was also observed to positively correlated with psoriasis area and severity index (PASI) (r = 0.405, P = 0.045). CONCLUSION Our present study exhibits some evidence for the landscape of lncRNAs implicated in psoriasis.

Abstract
Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are two common multisystem autoimmune diseases that share, among others, many clinical manifestations and serological features. The role of long non-coding RNAs (lncRNAs) has been of particular interest in the pathogenesis of autoimmune diseases. Here, we aimed to summarize the roles of lncRNAs as emerging novel biomarkers and therapeutic targets in SLE and RA. We conducted a narrative review summarizing original articles on lncRNAs associated with SLE and RA, published until November 1, 2021. Based on the studies on lncRNA expression profiles in samples (including PBMCs, serum, and exosomes), it was noted that most of the current research is focused on investigating the regulatory mechanisms of these lncRNAs in SLE and/or RA. Several lncRNAs have been hypothesized to play key roles in these diseases. In SLE, lncRNAs such as GAS5, NEAT1, TUG1, linc0949, and linc0597 are dysregulated and may serve as emerging novel biomarkers and therapeutic targets. In RA, many validated lncRNAs, such as HOTAIR, GAS5, and HIX003209, have been identified as promising novel biomarkers for both diagnosis and treatment. The shared lncRNAs, for example, GAS5, may participate in SLE pathogenesis through the mitogen-activated protein kinase pathway and trigger the AMP-activated protein kinase pathway in RA. Here, we summarize the data on key lncRNAs that may drive the pathogenesis of SLE and RA and could potentially serve as emerging novel biomarkers and therapeutic targets in the coming future.

ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1368. [PMID: 34733920 PMCID: PMC8506560 DOI: 10.21037/atm-21-1362] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 06/20/2021] [Indexed: 01/01/2023]
Abstract
Background Fibroblast-like synoviocytes (FLSs), which can migrate and directly invade the cartilage and the bone, are crucial players in joint damage in rheumatoid arthritis (RA). Nevertheless, the detailed mechanisms underlying the aberrant activation of RA FLSs remain unclear. Several studies have attempted to explore the relationship between long non-coding RNAs (lncRNAs) and RA pathology; however, the role of lncRNAs in RA is unknown. The present study aimed to determine the functions of tumor necrosis factor-α and heterogeneous nuclear ribonucleoprotein L-related immunoregulatory lincRNA (THRIL) in RA FLSs migration and invasion. Methods Small interfering RNA targeting THRIL or lentivirus overexpressing THRIL was used to knockdown or overexpress THRIL. Quantitative reverse transcription polymerase chain reaction (PCR) was employed for the detection of RNA expression. The proliferation rate of RA FLSs was measured using a 5-ethynyl-2'-deoxyuridine (EdU) incorporation assay. Migration and invasion were detected using a transwell chamber. Downstream targets were identified using a human cell cycle real-time PCR array and a human cell motility real-time PCR array. Results A significant decrease in THRIL expression was found in RA FLSs compared with cells from healthy control (HC)patients. THRIL is mainly localized in the nucleus. Knockdown of THRIL increased the proliferation, migration, and invasion of RA FLSs. In contrast, THRIL overexpression had the opposite effect. THRIL knockdown increased interleukin-1β (IL-1β)-triggered expression of matrix metalloproteinase (MMP)-1, MMP-3, and MMP-13. THRIL overexpression led to a significant decrease in MMP-13 expression in response to stimulation with IL-1β. Furthermore, we observed that the expression levels of cyclin-dependent kinase 1 (CDK1) and G2 and S phase-expressed-1 (GTSE1), both of which are associated with cellular mobility and proliferation, were downregulated with THRIL overexpression. Conclusions Reduced expression of lncRNA THRIL represses the proliferation, migration, and invasion of RA FLSs, suggesting that lncRNA THRIL might be a potential target for RA therapy.

Abstract
BACKGROUND Circular RNA (circRNA) is a type of closed circular noncoding RNA (ncRNA), mostly formed by back-splicing or alternative splicing of pre-messenger RNA (mRNA). The aim of this study was to explore the expression profile of circRNA in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and discover potential molecular markers of AS. METHODS The circRNA microarray technology was used to detect the expression of circRNAs in the peripheral blood of 6 patients with AS and 6 healthy controls (HC). To screen the differentially expressed circRNAs by fold change (FC) and P value, these differentially expressed circRNAs were analyzed by bioinformatics. In 60 cases of AS and 30 cases of HC, 4 circRNAs were subjected to real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and their correlation with various clinical indicators was analyzed. Finally, the receiver operating characteristic (ROC) curve was used to analyze their potential as AS diagnostic markers. RESULTS The microarray results showed that there were 1369 significantly differently expressed (P < 0.05, FC > 1.5) circRNAs between the AS and HC groups (675 upregulated and 694 downregulated). The results of bioinformatics analysis suggested that they were mainly involved in "enzyme binding," "adenosine ribonucleotide binding," "MAPK signaling pathway", etc. The RT-qPCR results showed that the expressions of hsa_circRNA_001544 (U = 486.5, P < 0.05) and hsa_circRNA_102532 (U = 645, P < 0.05) were significantly different between the AS group and the HC group. The AS group was further divided into two subgroups: active AS (ASA) and stable AS (ASS). After analysis, it was found that compared with the HC group, hsa_circRNA_001544 was significantly increased in both ASA (U = 214, P < 0.05) and ASS groups (U = 273, P < 0.05), while hsa_circRNA_008961 (U = 250, P < 0.05) and hsa_circRNA_102532 (U = 295, P < 0.05) were only significantly increased in the ASA group. Furthermore, hsa_circRNA_012732 was significantly different between the ASA and ASS groups (U = 194, P < 0.05), and there was no statistical significance among the remaining groups. Correlation analysis results showed that hsa_circRNA_012732 was negatively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), high-sensitivity C-reactive protein (hsCRP), and globulin (GLOB) and positively correlated with lymphocyte count (LY), mean corpusular volume, and albumin (ALB), and hsa_circRNA_008961 was negatively correlated with platelet (PLT) count. ROC curve analysis showed that hsa_circRNA_001544 (95% CI = 0.610-0.831, P < 0.05) and hsa_circRNA_102532 (95% CI = 0.521-0.762, P < 0.05) were statistically significant, and their area under curve (AUC) values were 0.720 and 0.642, respectively. CONCLUSIONS There are differentially expressed circRNAs in PBMCs of AS patients, and they may be involved in the occurrence and development of AS. Among these differentially expressed circRNAs, hsa_circRNA_012732 has the potential to become an indicator of disease activity, and hsa_circRNA_001544 has the potential to become a molecular marker for AS diagnosis.

Abstract
Objectives In recent years, long non‐coding RNAs (lncRNAs) have been found to play a role in the occurrence, progression and prognosis of chronic musculoskeletal disorders. Design and methods Literature exploring on PubMed was conducted using the combination of keywords 'LncRNA' and each of the following: 'osteoarthritis', 'rheumatoid arthritis', 'osteoporosis', 'osteogenesis', 'osteoclastogenesis', 'gout arthritis', 'Kashin‐Beck disease', 'ankylosing spondylitis', 'cervical spondylotic myelopathy', 'intervertebral disc degeneration', 'human muscle disease' and 'muscle hypertrophy and atrophy'. For each disorder, we focused on the publications in the last five years (5/1/2016‐2021/5/1, except for Kashin‐Beck disease). Finally, we excluded publications that had been reported in reviews of various musculoskeletal disorders during the last three years. Here, we summarized the progress of research on the role of lncRNA in multiple pathological processes during musculoskeletal disorders. Results LncRNAs play a crucial role in regulating downstream gene expression and maintaining function and homeostasis of cells, especially in chondrocytes, synovial cells, osteoblasts, osteoclasts and skeletal muscle cells. Conclusions Understanding the mechanisms of lncRNAs in musculoskeletal disorders may provide promising strategies for clinical practice.

Abstract
Fibrosis is a typical aging-related pathological process involving almost all organs. It is usually initiated by organic injury and leads to the gradual decline of organ function or even loss. Circular RNAs (circRNAs) are being hailed as a newly rediscovered class of covalently closed transcripts without a 5' cap or 3' tail which draw increasing attention. In particular, circRNAs have been identified to be involved in the multifaceted processes of fibrosis in various organs, including the heart, liver, lung, and kidney. As more and more circRNAs are functionally characterized, they have become novel therapies for fibrosis. In this review, we systematically summarized current studies regarding the roles of circRNAs in fibrosis and shed light on the basis of circRNAs as a potential treatment for fibrosis.

Abstract
INTRODUCTION Juvenile idiopathic arthritis (JIA) is a chronic disease characterized by persistent joint inflammation. JIA is the most common pediatric chronic rheumatic disease and no curative therapy is currently available. Methotrexate (MTX) is an important treatment for JIA even though a high inter-individual variability in response is observed in patients. Among the factors of this variability, genetics and epigenetics might play an important role. AREAS COVERED This review summarizes the results of pharmacogenetic and pharmacoepigenetic studies regarding MTX response in JIA. Studies considering epigenetic factors in JIA patients are still very limited, therefore this review includes also studies performed in adult patients with rheumatoid arthritis. Moreover, the relevance of biomarkers measured in blood or urine of JIA patients in relation to MTX treatment is discussed. EXPERT OPINION Nowadays, even though many pharmacogenomics studies have been published, a specific genetic marker predictor of MTX efficacy or adverse events has not yet been identified. Encouraging results are available and great expectations rely on the study of epigenetics. Future studies are needed in order to identify genetic and epigenetic biomarkers that can be implemented in the clinical practice.

Abstract
Rheumatoid arthritis (RA), recognized as a common chronic autoimmune disease, is characterized by the excessive proliferation and inflammatory infiltration of fibroblast-like synoviocytes (FLS). In this study, our purpose is to elucidate the mechanisms of triptolide (TPL) in the treatment of RA by regulating the long non-coding RNA (lncRNA) ENST00000619282, which promoted apoptosis and reduced inflammatory infiltration of FLS in RA (RA-FLS). RA-FLS was treated with different concentrations of TPL at different time points. CCK-8 assay, ELISA, RT-qPCR, immunofluorescence, TUNEL assay, and the transmission electron microscopy were used to measure the changes of cell viability, apoptosis, and the release of inflammatory cytokines. Next, the involvement of ENST00000619282 in TPL-mediated protection against RA was explored. ENST00000619282 expression was significantly increased in the peripheral blood mononuclear cells (PBMCs) of RA patients. ENST0000061928 expression in RA PBMCs was positively associated with ESR, RF, CCP, and DAS28, while TPL treatment led to a downregulation of ENST00000619282. In addition, ENST00000619282 was significantly increased in RA-FLS. Furthermore, overexpression of ENST00000619282 elevated the levels of pro-apoptotic and pro-inflammatory factors, while reduced the levels of anti-apoptotic proteins and antiinflammatory factors. Besides, TPL treatment could reverse these effects by ENST00000619282 overexpression. The anti-RA potential of TPL might be achieved by downregulating ENST00000619282, thereby promoting apoptosis, and reducing the inflammatory response in RA.

Abstract
BACKGROUND Circular RNAs (circRNAs) are associated with rheumatoid arthritis (RA) development. The purpose of this study is to explore the function and mechanism of circRNA fragile mental retardation 2 (circ-AFF2) in the processes of rheumatoid arthritis fibroblast-like synoviocytes (RAFLSs). METHODS Circ-AFF2, microRNA (miR)-650, and 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) levels were determined in synovial tissues of RA and RAFLSs by quantitative reverse transcription polymerase chain reaction or Western blotting. Cell proliferation, inflammatory response, apoptosis, caspase3 activity, migration, invasion, and epithelial-mesenchymal transition (EMT) were investigated using Cell Counting Kit-8 (CCK-8), enzyme-linked immunosorbent assay (ELISA), flow cytometry, Transwell, and Western blotting analyses. Dual-luciferase reporter, RNA immunoprecipitation (RIP), and pull-down assays were performed to assess the binding relationship. RESULTS Circ-AFF2 expression level was enhanced in synovial tissues of RA and RAFLSs. Circ-AFF2 overexpression facilitated cell proliferation, inflammatory response, migration, invasion, and EMT and repressed apoptosis in RAFLSs. Circ-AFF2 downregulation played an opposite role. Circ-AFF2 targeted miR-650, and miR-650 downregulation reversed the effect of circ-AFF2 interference on RAFLS processes. CNP was targeted by miR-650, and circ-AFF2 increased CNP expression by regulating miR-650. MiR-650 overexpression constrained cell proliferation, inflammatory response, migration, invasion, and EMT and contributed to apoptosis by decreasing CNP in RAFLSs. CONCLUSION Circ-AFF2 promoted proliferation, inflammatory response, migration, and invasion of RAFLSs by modulating the miR-650/CNP axis.
