[PMID: 37251843 PMCID: PMC10213199 DOI: 10.1016/j.heliyon.2023.e16143] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 04/21/2023] [Accepted: 05/06/2023] [Indexed: 05/31/2023] Open
Abstract
Ethnopharmacological relevance Jian-yan-ling (JYL) is a drug used in traditional Chinese medicine (TCM) prescriptions for the treatment of tumors after radiotherapy and chemotherapy, to effectively alleviate leukocytopenia. However, the genetic mechanisms underlying the function of JYL remain unclear. Aim of the study This study aimed to explore the RNA changes and potential biological processes related to the anti-aging or life-extending effects of JYL treatments. Materials and methods In vivo treatments were performed using Canton-S Drosophila corresponding to three groups: control, low-concentration (low-conc.), and high-concentration (high-conc.) groups. The low-conc. And the high-conc. Groups were treated with 4 mg/mL JYL and 8 mg/mL JYL, respectively. Thirty Drosophila eggs were placed in each vial, and the third instar larvae and adults 7 and 21 days post-eclosion were collected for RNA sequencing, irrespective of the gender.In vitro treatments were conducted using humanized immune cell lines HL60 and Jurkat, which were divided into 3 groups: control (0 μg/mL JYL), low-concentration (40 μg/mL JYL), and high-concentration (80 μg/mL JYL). The cells were collected after 48 h of each JYL drug treatment. Both the Drosophila and cell samples were analyzed using RNA sequencing. Results The in vivo experiments revealed 74 upregulated genes in the low-concentration group, and CG13078 was a commonly downregulated differential gene, which is involved in ascorbate iron reductase activity. Further analysis of the co-expression map identified the key genes: regulatory particle non-ATPase (RPN), regulatory particle triple-A ATPase (RPT), and tripeptidyl-peptidase II (TPP II). For the in vitro experiments, 19 co-differential genes were compared between different concentrations of the HL 60 cell line, of which three genes were upregulated: LOC107987457 (phostensin-like gene), HSPA1A (heat shock protein family A member 1 A), and H2AC19 (H2A clustered histone 19). In the HL 60 cell line, JYL activated proteasome-related functions. In the Jurkat cell line, there were no common differential genes despite the presence of a dosage-dependent trend. Conclusions The RNA-seq results showed that the traditional Chinese medicine JYL has longevity and anti-aging effects, indicating that further investigation is required.

[PMID: 36370296 DOI: 10.1007/s11033-022-08043-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 10/18/2022] [Indexed: 11/13/2022]
Abstract
BACKGROUND Synovial inflammation, characterized by the activation of synovial fibroblasts (SFs), is a crucial factor to drive the progression of rheumatoid arthritis (RA). Polyene phosphatidylcholine (PPC), the classic hepatoprotective drug, has been reported to ameliorate arthritis in animals. However, the molecular mechanism remains poorly understood. METHODS AND RESULTS: Using in vitro primary synovial fibroblast (SFs) culture system, we revealed that phosphatase and tension homolog deleted on chromosome 10 (PTEN), a tumor suppressor, mediates the anti-inflammatory effect of PPC in lipopolysaccharide (LPS)-stimulated primary SFs. PPC decreased the production of TNF-α and IL-6 production while elevating the level of IL-10 and TGF-β. Furthermore, PPC up-regulated the expression of PTEN, but inhibited the expression of p-AKT (ser473) and PI3K-p85α. Moreover, pre-treatment of SF1670 (the inhibitor of PTEN) or 740Y-P (the agonist of AKT/PI3K pathways) partially abrogated the anti-inflammatory effect of PPC. In addition, PPC could inhibit the expression of GLUT4, a key transporter of glucose that fuels the glycolysis, which is accompanied by the expression downregualtion of glycolytic enzymes PFKFB3 and PKM2. Furthermore, PPC could reduce ROS production and mitochondrial membrane potential in LPS-stimulated SFs and MH7A cell line. CONCLUSION The present study supported that PPC can alleviate synovial inflammation, which involves in the elevation of PTEN and blockage of glycolysis.

Abstract
Background RAF and ERK pathways are known to be activated in human rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS), which play an important role in the pathogenesis and destruction of RA. Gentisic acid (GA) was a natural product derived from plants, which has been reported can attenuate pressure overload‐induced cardiac hypertrophy and fibrosis in mice through inhibition of the ERK1/2 pathway. Whether GA can inhibit the occurrence and development of RA through RAF/ERK signaling pathway has not been reported. The purpose of this study is to determine whether GA may have a certain therapeutic effect on RA-FLS. Method Bovine type II collagen was used to establish a rat model of rheumatism. Enzyme-linked immunosorbent assay was used to detect inflammatory factors, anti-inflammatory mediators, and rheumatoid factor. Hematoxylin and eosin and TUNEL staining were used to detect the effect of GA on histochemical with rheumatoid arthritis. RAF, ERK, and p-ERK expressions in synovial tissue were measured by western blot and immunohistochemical. Besides, human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A was used to investigate the biological behavior influenced by GA. Apoptosis assay was performed to detect apoptosis of GA on MH7A cells. Transwell invasion assay was performed to detect the ability of cell migration. Result The result showed that GA could reduce joint swelling and inflammation. At the same time, it can also promote the apoptosis of synovial cells and down-regulate the RAF/ERK pathway. Conclusion GA may ameliorate inflammatory factors’ abnormality, synovial hyperplasia, and apoptosis of synovium via inhibiting the RAF/ERK signaling pathway.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease. Synovial hyperplasia and persistent inflammation serve as its typical pathological manifestations, which ultimately lead to joint destruction and function loss. Both clinical observations and metabolomics studies have revealed the prevalence of metabolic disorders in RA. In inflammatory immune microenvironments, energy metabolism is profoundly changed. Increasingly evidences suggest that this abnormality is involved in the occurrence and development of RA-related inflammation. Unsurprisingly, many energy metabolism sensors have been confirmed with immunoregulatory properties. As a representative, silent information regulator type 1 (Sirt1) controls many aspects of immune cells, such as cell lifespan, polarization, and secretion by functioning as a transcriptional regulator. Because of the profound clinical implication, researches on Sirt1 in the regulation of energy metabolism and immune functions under RA conditions have gradually gained momentum. This signaling balances glycolysis, lipid metabolism and insulin secretion orchestrating with other metabolism sensors, and consequently affects immune milieu through a so-called metabolism-immune feedback mechanism. This article reviews the involvement of Sirt1 in RA by discussing its impacts on energy metabolism and immune functions, and specially highlights the potential of Sirt1-targeting anti-rheumatic regimens. It also provides a theoretical basis for clarifying the mystery about the high incidence of metabolic complications in RA patients and identifying new anti-rheumatic reagents.

Association analysis of juvenile idiopathic arthritis genetic susceptibility factors in Estonian patients. Clin Rheumatol 2021; 40:4157-4165. [PMID: 34101054 PMCID: PMC8463396 DOI: 10.1007/s10067-021-05756-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 04/26/2021] [Accepted: 04/27/2021] [Indexed: 12/16/2022]
Abstract
Background Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic condition of childhood. Genetic association studies have revealed several JIA susceptibility loci with the strongest effect size observed in the human leukocyte antigen (HLA) region. Genome-wide association studies have augmented the number of JIA-associated loci, particularly for non-HLA genes. The aim of this study was to identify new associations at non-HLA loci predisposing to the risk of JIA development in Estonian patients. Methods We performed genome-wide association analyses in an entire JIA case–control sample (All-JIA) and in a case–control sample for oligoarticular JIA, the most prevalent JIA subtype. The entire cohort was genotyped using the Illumina HumanOmniExpress BeadChip arrays. After imputation, 16,583,468 variants were analyzed in 263 cases and 6956 controls. Results We demonstrated nominal evidence of association for 12 novel non-HLA loci not previously implicated in JIA predisposition. We replicated known JIA associations in CLEC16A and VCTN1 regions in the oligoarticular JIA sample. The strongest associations in the All-JIA analysis were identified at PRKG1 (P = 2,54 × 10−6), LTBP1 (P = 9,45 × 10−6), and ELMO1 (P = 1,05 × 10−5). In the oligoarticular JIA analysis, the strongest associations were identified at NFIA (P = 5,05 × 10−6), LTBP1 (P = 9,95 × 10−6), MX1 (P = 1,65 × 10−5), and CD200R1 (P = 2,59 × 10−5). Conclusion This study increases the number of known JIA risk loci and provides additional evidence for the existence of overlapping genetic risk loci between JIA and other autoimmune diseases, particularly rheumatoid arthritis. The reported loci are involved in molecular pathways of immunological relevance and likely represent genomic regions that confer susceptibility to JIA in Estonian patients.
Key Points • Juvenile idiopathic arthritis (JIA) is the most common childhood rheumatic disease with heterogeneous presentation and genetic predisposition. • Present genome-wide association study for Estonian JIA patients is first of its kind in Northern and Northeastern Europe. • The results of the present study increase the knowledge about JIA risk loci replicating some previously described associations, so adding weight to their relevance and describing novel loci. • The study provides additional evidence for the existence of overlapping genetic risk loci between JIA and other autoimmune diseases, particularly rheumatoid arthritis. |

Abstract
Activating transcription factor 2(ATF2), a transcription factor belonging to the AP-1 family, plays an important role in inflammation. However, its biological functions and underlying molecular mechanisms in rheumatoid arthritis (RA) remain unclear. Western blot and immunohistochemistry were used to identify the expression of ATF2 and Sprouty2(SPRY2) in RA synovial tissues. SW982 cells were stimulated by TNF-α to establish an in vitro RA fibroblast-like synoviocyte (RA-FLS) model. Transwell and monolayer wound-healing were used to detect cell migration and invasion. RNA interference (si-ATF2) and adenovirus vector (Ad-SPRY2) methods were employed to manipulate ATF2 or SPRY2 expression in SW982 cells. The protein expression and phosphorylation levels in SW982 cells were evaluated by western blot. ATF2 expression and phosphorylation were upregulated in the RA synovial tissues. In RA-FLS model, ATF2 expression and phosphorylation were increased in a time-dependent manner. ATF2 knockdown inhibited the migration and invasion of RA-FLS model, reducing the inflammatory factors, which was consistent with the influence on cell behaviors caused by SPRY2 overexpression. Moreover, SPRY2 overexpression inhibited the TNF-α-induced phosphorylation of ERK and ATF2 in SW982 cells. The high expression and phosphorylation of ATF2 promoted migration and invasion of RA-FLSs. SPRY2 might inhibited the inflammatory responses of RA-FLSs via suppressing ERK-ATF2 pathway.

Abstract
Rheumatoid arthritis (RA) is characterized by tumor-like expansion of the synovium and the subsequent destruction of adjacent articular cartilage and bone. The latest studies proved phosphatase and tension homolog deleted on chromosome 10 (PTEN) might contribute to the surviving, proliferation and pro-inflammatory cytokines in RA. The purpose of this study was to explore the function and underlying mechanisms of PTEN in RA pro-inflammatory cytokines and chemokines of fibroblast-like synoviocytes (FLSs). Increased level of PTEN was observed in adjuvant-induced arthritis (AIA) FLSs in comparison to normal rats. Increased concentrations of pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β), chemokines (CCL-2 and CCL-3), VCAM-1 and VEGF-α expression were observed in FLSs with PTEN inhibitor bpv or PTEN-RNAi. Moreover, co-incubation FLSs with overexpression vector with PTEN-GV141 reduced the expression of pro-inflammatory cytokines, chemokines, VCAM-1 and VEGF-α in AIA. Interestingly, we also found DNA methylation could regulate PTEN expression and activation of AKT signaling was with a change of PTEN. Altogether, our findings in the present study suggested that PTEN might play a pivotal role during pro-inflammatory cytokines and chemokines of FLSs through activation of AKT signaling pathway. In addition, PTEN expression may be regulated by DNA methylation in the pathogenesis of AIA.

Abstract
SCOPE Rheumatoid arthritis (RA) is an autoimmune disorder related to the inflammation of cartilage due to the infiltration of inflammatory cells. Sargassum serratifolium, a brown alga, possesses strong anti-inflammatory activities. METHODS AND RESULTS The effect of meroterpenoid-rich fraction from the ethanol extract of S. serratifolium (MES) on RA and its underlying mechanisms on the inhibition of RA using a collagen-induced arthritis (CIA) mouse model are examined. The results show that MES ameliorates paw swelling and reduces the arthritis score. MES considerably decreases the secretion of pro-inflammatory cytokines in the serum and joint tissue of mice. Histopathological analysis demonstrates that MES strongly inhibited bone damage and inflammatory cell intrusion in the joint tissue. The expression of inflammatory enzymes and adhesion molecules is significantly inhibited in the serum and joint tissue of MES-fed mice. In addition, MES downregulates the nuclear factor κB (NF-κB) signaling pathway by suppressing the phosphorylation of protein kinase B, c-Jun N-terminal kinase, and p38 mitogen-activated protein kinases. CONCLUSIONS MES supplementation remarkably reduces inflammatory response in CIA mouse model. These results indicate that MES can be used as a pharmaceutical agent against RA.

Abstract
Fibroblast-like synoviocytes (FLSs) play an essential role in rheumatoid arthritis (RA) by promoting synovitis, pannus growth and cartilage/bone destruction. Increased proliferation, migration and invasion of FLSs greatly contribute to RA initiation and progression. Dual-specificity tyrosine-regulated kinase 1A (Dyrk1A), a serine/threonine kinase, regulates MAPK pathway activation, and governs the proliferation and differentiation of neuronal progenitor cells and cancer cells. Till now, the expression and possible function of Dyrk1A in RA FLSs have not been explored. In this study, we detected an increased expression of Dyrk1A both in the synovial tissues of RA patients and in a TNF-α-induced FLSs activation model. CCK-8 and Edu assays revealed that Dyrk1A knockdown inhibited TNF-α-induced FLSs proliferation. Moreover, inhibiting Dyrk1A expression apparently prevented the migration and invasion capability of FLSs accompanied by a decreased MMP-3 and -9 expression. To investigate the molecular mechanism through which Dyrk1A modulates FLSs activities, we evaluated the effects of Dyrk1A on Spry2, a negativity modulator of ERK MAPK pathway. Western blot assay demonstrated that Dyrk1A silencing significantly increased Spry2 expression and suppressed the phosphorylation of ERK in TNF-α-treated FLSs. Taken together, our results indicated that Dyrk1A might promote FLSs proliferation, migration and invasion by suppressing Spry2 expression and activating the ERK MAPK signaling pathway in RA.

Abstract
The function of microRNA‑130a in development and progression of osteoarthritis was determined. In osteoarthritis patients, the serum levels of microRNA‑130a were decreased, compared with normal group. Overexpression of microRNA‑130a increased cell proliferation and decreased apoptosis of chondrocytes, and downregulation of microRNA‑130a also decreased cell proliferation and induced apoptosis in chondrocytes. Downregulation of microRNA‑130a promoted Bax and caspase‑3/9 protein expression, increased inflammation divisors and suppressed the PTEN/PI3K/Akt signaling pathway. PTEN inhibitor, VO‑Ohpic trihydrate increased the destructive effect of microRNA‑130a on cell proliferation of chondrocytes. PI3K inhibitor, wortmannin also increased the destructive effect of microRNA‑130a on osteoarthritis. In conclusion, microRNA‑130a is an important regulator of osteoarthritis in chondrocytes through PTEN/PI3K/Akt signaling pathway.

Effects of lentivirus-mediated ornithine decarboxylase gene on the proliferation and apoptosis of fibroblast-like synoviocytes in rats with arthritis. Life Sci 2018; 194:224-230. [PMID: 28986097 DOI: 10.1016/j.lfs.2017.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2017] [Revised: 09/23/2017] [Accepted: 10/02/2017] [Indexed: 11/24/2022]
Abstract
OBJECTIVE This study aimed to explore the effects of lentivirus-mediated ornithine decarboxylase (ODC) gene on the proliferation and apoptosis of fibroblast-like synoviocytes (FLSs) in rats with rheumatoid arthritis (RA). METHODS Twenty Lewis rats were randomized into control group (ten rats without processing) and RA group (ten rats of adjuvant-induced arthritis). The third-generation FLSs were randomized into test, control and blank groups. MTT assay and flow cytometry were employed to detect cell proliferation and apoptosis, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor α (TNF-α), interferon-γ (IFN-γ), and interleukin-2 (IL-2). RESULTS Lewis rats in the RA group became ill from 11days on and got seriously ill 18days after modeling. However, rats in the control group had no obvious change. MTT assay showed that the test group had higher cell proliferation than the blank and control groups (P1<0.001; P2<0.001). Flow cytometry revealed that the apoptosis of FLSs in the test group was significantly lower than that in the blank and control groups (P1<0.001; P2<0.001). ELISA showed that the test group had higher TNF-α, IFN-γ and IL-2 level than the control and blank groups (all P<0.001), but no significant difference was found between the control and blank groups (all P>0.05). CONCLUSION The results indicated that overexpression of ODC gene promotes the proliferation while suppressing apoptosis of FLSs in rats with RA.

Abstract
Fibroblast growth factor (FGF) and bone morphogenetic protein (BMP) play essential roles in bone formation and osteoblast activity through the extracellular signal-regulated kinase 1/2 (ERK1/2) and Smad pathways. Sprouty family members are intracellular inhibitors of the FGF signaling pathway, and four orthologs of Sprouty have been identified in mammals. In vivo analyses have revealed that Sprouty2 is associated with bone formation. However, the mechanism by which the Sprouty family controls bone formation has not been clarified. In this study, we investigated the involvement of Sprouty2 in osteoblast proliferation and differentiation. We examined Sprouty2 expression in MC3T3-E1 cells, and found that high levels of Sprouty2 expression were induced by basic FGF stimulation. Overexpression of Sprouty2 in MC3T3-E1 cells resulted in suppressed proliferation compared with control cells. Sprouty2 negatively regulated the phosphorylation of ERK1/2 after basic FGF stimulation, and of Smad1/5/8 after BMP stimulation. Furthermore, Sprouty2 suppressed the expression of osterix, alkaline phosphatase, and osteocalcin mRNA, which are markers of osteoblast differentiation. Additionally, Sprouty2 inhibited osteoblast matrix mineralization. These results suggest that Sprouty2 is involved in the control of osteoblast proliferation and differentiation by downregulating the FGF-ERK1/2 and BMP-Smad pathways, and suppresses the induction of markers of osteoblast differentiation.

Abstract
Astrocyte elevated gene-1 (AEG-1) was initially induced by HIV-1 infection and involved in tumor progression, migration and invasion as a nuclear factor-κB (NF-κB)-dependent gene. The present study we intended to investigate the protein expression of AEG-1 significantly associated with rheumatoid arthritis. Western blot analysis and immunohistochemistry demonstrated that AEG-1 was upregulated in synovial tissue of RA patients compared with the controls. Double immunofluorescent staining suggested that AEG-1 was expressed in fibroblast-like synoviocytes (FLS) of RA patients. Furthermore, the expression of AEG-1 in FLS was increased in time-dependent manner by TNF-α stimulation. Upon TNF-α-treated FLS, AEG-1 transferred from the cytoplasm to nucleus where it interacted with the p65 subunit of NF-κB, as examined by immunoprecipitation and immunofluorescent staining assay. Moreover, the inhibition of AEG-1 by RNA interference significantly suppressed TNF-α-induced IL-6 and MMP-3 expression, leading to attenuation of FLS migration and invasion and markedly decreased the phosphorylation of P65 and IκBα, as well as AKT in FLS. Collectively, Our findings provided evidence that AEG-1 contributed to the production of inflammatory cytokines, migration and invasion of RA FLS, and underscored the importance of AEG-1 in the inflammation process of RA.

Inhibition of Sprouty2 polarizes macrophages toward an M2 phenotype by stimulation with interferon γ and Porphyromonas gingivalis lipopolysaccharide. IMMUNITY INFLAMMATION AND DISEASE 2016; 4:98-110.

Abstract
Periodontitis is a chronic inflammatory disorder caused by specific bacteria residing in the biofilm, particularly Porphyromonas gingivalis (Pg). Sprouty2 (Spry2) functions as a negative regulator of the fibroblast growth factor (FGF) signaling pathway. We previously demonstrated that sequestration of Spry2 induced proliferation and osteogenesis in osteoblastic cells by basic FGF (bFGF) and epidermal growth factor (EGF) stimulation in vitro, but diminished cell proliferation in gingival epithelial cells. In addition, Spry2 knockdown in combination with bFGF and EGF stimulation increases periodontal ligament cell proliferation and migration accompanied by prevention of osteoblastic differentiation. In this study, we investigated the mechanisms through which Spry2 depletion by interferon (IFN) γ and Pg lipopolysaccharide (LPS) stimulation affected the physiology of macrophages in vitro. Transfection of macrophages with Spry2 small‐interfering RNA (siRNA) promoted the expression of genes characteristic of M2 alternative activated macrophages, induced interleukin (IL)‐10 expression, and enhanced arginase activity, even in cells stimulated with IFNγ and Pg LPS. In addition, we found that phosphoinositide 3‐kinase (PI3K) and AKT activation by Spry2 downregulation enhanced efferocytosis of apoptotic cells by increasing Rac1 activation and decreasing nuclear factor kappa B (NFκB) p65 phosphorylation but not signal transducer and activator of transcription 1 (STAT1) phosphorylation. Collectively, our results suggested that topical administration of Spry2 inhibitors may efficiently resolve inflammation in periodontal disease as macrophage‐based anti‐inflammatory immunotherapy and may create a suitable environment for periodontal wound healing. These in vitro findings provide a molecular basis for new therapeutic approaches in periodontal tissue regeneration.
