Sophoridine exerts anti-arthritic effects on fibroblast-like synoviocytes and collagen-induced arthritis in rats. Phytother Res 2024.

Abstract
The discovery of alternative medicines with fewer adverse effects is urgently needed for rheumatoid arthritis (RA). Sophoridine (SR), the naturally occurring quinolizidine alkaloid isolated from the leguminous sophora species, has been demonstrated to possess a wide range of pharmacological activities. However, the effect of SR on RA remains unknown. In this study, the collagen-induced arthritis (CIA) rat model and tumor necrosis factor alpha (TNFα)-induced fibroblast-like synoviocytes (FLSs) were utilized to investigate the inhibitory effect of SR on RA. The anti-arthritic effect of SR was evaluated using the CIA rat model in vivo and TNFα-stimulated FLSs in vitro. Mechanistically, potential therapeutic targets and pathways of SR in RA were analyzed through drug target databases and disease databases, and validation was carried out through immunofluorescence, immunohistochemistry, and Western blot. The in vivo results revealed that SR treatment effectively ameliorated synovial inflammation and bone erosion in rats with CIA. The in vitro studies showed that SR could significantly suppress the proliferation and migration in TNFα-induced arthritic FLSs. Mechanistically, SR treatment efficiently inhibited the activation of MAPKs (JNK and p38) and NF-κB pathways in TNFα-induced arthritic FLSs. These findings were further substantiated by Immunohistochemistry results in the CIA rat. SR exerts an anti-arthritic effect in CIA rats through inhibition of the pathogenic characteristic of arthritic FLSs via suppressing NF-κB and MAPKs (JNK and p38) signaling pathways. SR may have a great potential for development as a novel therapeutic agent for RA treatment.

Ye P, Wang QH, Liu CS, Li GH, Olatunji OJ, Lin JT, Zuo J. SIRT1 inhibitors within Qing-Luo-Yin alleviated white adipose tissues-mediated inflammation in antigen-induced arthritis mice. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 122:155132. [PMID: 37844379 DOI: 10.1016/j.phymed.2023.155132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/17/2023] [Accepted: 10/03/2023] [Indexed: 10/18/2023]
Abstract
BACKGROUND White adipose tissues (WAT) release large amounts of inflammatory mediators, which are responsible for the pathology of rheumatoid arthritis (RA). PURPOSE The current study investigated the involvement of WAT in the treatments of antigen-induced arthritis (AIA) mice with the herbal formula Qing-Luo-Yin (QLY). METHODS Cytokines and biochemical/metabolic indicators were determined by ELISA and colorimetry methods, respectively. Monocytes were analyzed by flow cytometry. Tissues were subjected to PCR, western-blot and histological analyses. Pre-adipocytes were cultured in the different mouse serum from the in vivo experiment, and some of them were treated by certain compounds or/and lipopolysaccharide. Afterwards, the catalytic activity and thermostability of SIRT1 were tested. Gene/protein expression and cytokine production were investigated too. NAMPT and SIRT1 were silenced in some cells by siRNA. RESULTS AIA mice suffered from inflammatory adipokines-mediated metabolism and immune disorders. Besides joint protective effects, QLY therapies favored adipocyte differentiation and suppressed inflammatory adipokines release. The up-regulation of fatty acid oxidation and inflammatory monocyte polarization was therefore inhibited in peripheral tissues. PPARγ expression was generally promoted by QLY. Whereas, SIRT1 activity was always impaired, indicated by the declined NAD+ levels and the increased ace-p65 expression. QLY effectively inhibited eNAMPT release in AIA mouse serum-cultured pre-adipocytes. This effect was antagonized by resveratrol (a SIRT1 agonist) and overshadowed by NAMPT silencing. QLY-related compounds berberine, dioscin and sophocarpine showed high binding affinities to SIRT1, stabilized this protein, and inhibited its deacetylation activity in vitro. Their effects on ace-p65 expression were weakened when SIRT1 was silenced. CONCLUSION SIRT1 inhibitors in QLY reduced eNAMPT production and up-regulated PPARγ in AIA mice, leading to inflammation remission. These clues show that except for the well-known anti-inflammatory functions, SIRT1 participates in inflammatory reactions too and could be a potential anti-rheumatic target.

Abstract
BACKGROUND Autoimmune diseases are diseases caused by tissue damage caused by the body's immune response to autoantibodies. Circular RNAs (CircRNAs) are a kind of special endogenous non-coding RNA that play a biological role by regulating gene transcription. METHODS In this work, we searched the PubMed, Web of Science (SCIE), National Science and Technology Library (NSTL), and ScienceDirect Online (SDOL) databases to summarize the impact of circRNAs on autoimmune diseases, especially the results of circRNAs in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). RESULTS The study on the function of circRNAs and autoimmune diseases further deepened our understanding of the development and pathogenesis of autoimmune diseases. CircRNAs may act as miRNA sponges to regulate biological processes and affect the occurrence and development of autoimmune diseases. CircRNAs are closely related to the pathogenesis of RA and SLE and may become potential biomarkers for the diagnosis and treatment of RA and SLE. CONCLUSION CircRNAs play an important role in the pathogenesis of RA, SLE and other autoimmune diseases, and are expected to provide new biomarkers for the diagnosis and treatment of autoimmune diseases. However, the function and mechanism of circRNAs in autoimmune diseases need more comprehensive research.

Abstract
Intestinal fibrosis is one of the common pathophysiological processes in inflammatory bowel diseases (IBDs). Previously it has been demonstrated that epithelial-mesenchymal transition (EMT) can contribute to the development of intestinal fibrosis. Here we report that conditional ablation of SIRT1, a class III lysine deacetylase, in intestinal epithelial cells exacerbated 2, 4, 6-trinitro-benzene sulfonic acid (TNBS) induced intestinal fibrosis in mice. SIRT1 activity, but not SIRT1 expression, was down-regulated during EMT likely due to up-regulation of its inhibitor deleted in breast cancer 1 (DBC1). TGF-β augmented the recruitment of KDM4A, a histone H3K9 demethylase, to the DBC1 promoter in cultured intestinal epithelial cells (IEC-6) leading to DBC1 trans-activation. KDM4A depletion or inhibition abrogated DBC1 induction by TGF-β and normalized SIRT1 activity. In addition, KDM4A deficiency attenuated TGF-β induced EMT in IEC-6 cells. In conclusion, our data identify a KDM4-DBC1-SIRT1 pathway that regulates EMT to contribute to intestinal fibrosis.

Abstract
Swelling and the progressive destruction of articular cartilage are major characteristics of rheumatoid arthritis (RA), a systemic autoimmune disease that directly affects the synovial joints and often causes severe disability in the affected positions. Recent studies have shown that type B synoviocytes, which are also called fibroblast-like synoviocytes (FLSs), as the most commonly and chiefly resident cells, play a crucial role in early-onset and disease progression by producing various mediators. During the pathogenesis of RA, the FLSs' phenotype is altered, and represent invasive behavior similar to that observed in tumor conditions. Modified and stressful microenvironment by FLSs leads to the recruitment of other immune cells and, eventually, pannus formation. The origins of this cancerous phenotype stem fundamentally from the significant metabolic changes in glucose, lipids, and oxygen metabolism pathways. Moreover, the genetic abnormalities and epigenetic alterations have recently been implicated in cancer-like behaviors of RA FLSs. In this review, we will focus on the mechanisms underlying the transformation of FLSs to a cancer-like phenotype during RA. A comprehensive understanding of these mechanisms may lead to devising more effective and targeted treatment strategies.

Abstract
Objective The disruption of metabolic events and changes to nutrient and oxygen availability due to sustained inflammation in RA increases the demand of bioenergetic and biosynthetic processes within the damaged tissue. The current study aimed to understand the molecular mechanisms of SLC7A5 (amino acid transporter) in synoviocytes of RA patients. Methods Synovial tissues were obtained from OA and RA patients. Fibroblast-like synoviocytes (FLS) were isolated, and SLC7A5 expression was examined by using RT-qPCR, immunofluorescence, and Western blotting. RNAi and antibody blocking treatments were used to knockdown SLC7A5 expression or to block its transporter activities. mTOR activity assay and MMP expression levels were monitored in RA FLS under amino acid deprivation or nutrient-rich conditions. Results RA FLS displayed significantly upregulated expression of SLC7A5 compared to OA FLS. Cytokine IL-1β was found to play a crucial role in upregulating SLC7A5 expression via the NF-κB pathway. Intervening SLC7A5 expression with RNAi or blocking its function by monoclonal antibody ameliorated MMP3 and MMP13 protein expression. Conversely, upregulation of SLC7A5 or tryptophan supplementation enhanced mTOR-P70S6K signals which promoted the protein translation of MMP3 and MMP13 in RA FLS. Conclusion Activated NF-κB pathway upregulates SLC7A5, which enhances the mTOR-P70S6K activity and MMP3 and MMP13 expression in RA FLS.

Abstract
Circular RNAs (circRNAs) have been demonstrated to play crucial roles in the development and progression of various types of cancers by serving as microRNA sponges to regulate the expression of target genes. Although in-depth studies of circRNAs have been conducted, their functional and pathological significance in autoimmune diseases, including rheumatoid arthritis (RA), remains unclear. Our previous study verified that hsa_circ_0088036 (circ0088036) is significantly elevated in peripheral blood mononuclear cells from patients with RA. The present study aimed to explore the roles of circ0088036 in the pathogenesis of RA. The circ0088036/miR-140-3p/silent information regulator 1 (SIRT 1) axis was predicted by bioinformatics tools. Circ0088036 was found to be aberrantly upregulated in fibroblast-like synoviocytes (FLSs) in RA compared with FLSs in osteoarthritis (OA). Functionally, upregulated circ0088036 promoted the proliferation and migration of RA-FLSs. Mechanistically, circ0088036 acted as a miR-140-3p sponge to upregulate SIRT 1 expression, subsequently promoting RA progression. In conclusion, this study revealed that circ0088036 may play an essential role in promoting synovial pathogenesis via the circ0088036/miR-140-3p/SIRT 1 axis in RA, providing new insight into circRNAs during RA progression.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints and joint destruction. Monocyte chemoattractant protein 1 (MCP‑1) is highly expressed in the joints of patients suffering from RA. The present study aimed to evaluate the effects of MCP‑1 on the phenotype of fibroblast‑like synoviocytes (FLSs) and their differentiation potential towards vascular endothelial cells. The expression of MCP‑1 in collagen‑induced arthritis (CIA) rats was investigated by PCR, ELISA and immunohistology. Cell proliferation induced by MCP‑1 was measured using a Cell Counting Kit‑8 (CCK‑8) and 5‑Bromo‑2‑deoxyuridine ELISA assay. In addition, the effects of MCP‑1 on the migration of FLSs was examined using a Transwell assay. Activation of PI3K and P38 were investigated by western blotting following MCP‑1 treatment. The vascular endothelial cell markers, tumor necrosis factor alpha (TNF‑α) and interleukin‑1 beta (IL‑β), were also examined by western blotting. LY294002 [PI3K inhibitor, (LY)] and SB203580 [P38 inhibitor, (SB)] were used to examine the proliferative and pro‑differentiation effect of PI3K and P38. The present findings showed that the expression level of MCP‑1 in the synovium of CIA rats was significantly higher compared with controls. The present in vitro study suggested that MCP‑1 increased the FLSs cell numbers with a maximal effect at 200 ng/ml, and induced the maximal phosphorylation of PI3K at 15 min and P38 at 30 min. In addition, MCP‑1 stimulation significantly increased the migration of FLSs. Furthermore, MCP‑1‑induced the expression of vascular endothelial growth factor and CD31 in FLSs. Suppression of PI3K and P38 was found to reduce MCP‑1 induced FLSs proliferation and migration, and decreased the expression levels of angiogenesis markers increased following MCP‑1 treatment. MCP‑1 was also found to increase the expression levels of both TNF‑α and IL‑β. Therefore, MCP‑1 could promote the proliferation and migration of FLSs, and was found to increase the expression levels of various angiogenesis markers via PI3K/P38, suggesting a role for this pathway in synovium hyperplasia in RA.

Long non-coding RNA PVT1 knockdown suppresses fibroblast-like synoviocyte inflammation and induces apoptosis in rheumatoid arthritis through demethylation of sirt6. J Biol Eng 2019; 13:60.

Abstract
Background As a type of chronic autoimmune joint disease, rheumatoid arthritis (RA) is a disorder, characterized by a variety of physical symptoms as well as RA fibroblast-like synoviocyte (RA-FLS) proliferation. More recently, long non-coding RNAs (lncRNAs) have been implicated in the progression of various diseases including the progression of RA. Hence, the aim of the current study was to investigate the role by which the lncRNA, plasmacytoma variant translocation 1 (PVT1), influences RA-FLSs and its ability to modulate the methylation of sirtuin 6 (sirt6). Methods RA rat models were initially established to determine the expression of PVT1 and sirt6 in synovial tissues and RA-FLSs. Elevation or depletion of PVT1 or sirt6 was achieved by means of transformation with plasmids in order to investigate their effects on RA-FLS proliferation, inflammation and apoptosis. The localization of PVT1 and its binding ability to the sirt6 promoter region were also explored in an attempt to elucidate the correlation between PVT1 and sirt6 methylation. Results High expression of PVT1 and low expression of sirt6 were detected in the synovial tissues and RA-FLSs of the rat models. RA-FLSs treated with sh-PVT1 or oe-sirt6 exhibited suppressed cell proliferation, inflammation and induced apoptosis. PVT1 was predominately localized in the nucleus while evidence was obtained indicating that it could bind to the sirt6 promoter to induce sirt6 methylation, thus inhibiting sirt6 transcription. PVT1 knockdown was observed to restore sirt6 expression through decreasing sirt6 methylation, thereby alleviating RA. Conclusion The key findings of the study provide evidence suggesting that, PVT1 knockdown is able to restrain RA progression by inhibiting sirt6 methylation to restore its expression.
