Li Z, Zhu X, Li C, Tang R, Zou Y, Liu S. Integrated serum metabolomics, 16S rRNA sequencing and bile acid profiling to reveal the potential mechanism of gentiopicroside against nonalcoholic steatohepatitis in lean mice. JOURNAL OF ETHNOPHARMACOLOGY 2024; 334:118526. [PMID: 38972531 DOI: 10.1016/j.jep.2024.118526] [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: 04/15/2024] [Revised: 07/02/2024] [Accepted: 07/04/2024] [Indexed: 07/09/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lean nonalcoholic steatohepatitis (NASH) poses a serious threat to public health worldwide. Herbs of the genus Gentiana have been used for centuries to treat hepatic disease or have been consumed for hepatic protection efficiency. Gentiopicroside (GPS), the main bioactive component of Gentiana herbs, has been shown to be beneficial for protecting the liver, improving intestinal disorders, modulating bile acid profiles, ameliorating alcoholic hepatosteatosis, and so on. It is plausible to speculate that GPS may hold potential as a therapeutic strategy for lean NASH. However, no related studies have been conducted thus far. AIM OF THE STUDY The present work aimed to investigate the benefit of GPS on NASH in a lean mouse model. MATERIALS AND METHODS NASH in a lean mouse model was successfully established via a published method. GPS of 50 and 100 mg/kg were orally administered to verify the effect. Untargeted metabolomics, 16S rDNA sequencing and bile acid (BA) profiling, as well as qPCR and Western blotting analysis were employed to investigate the mechanism underlying the alleviating effect. RESULTS GPS significantly reduced the increase in serum biochemicals and liver index, and attenuated the accumulation of fat in the livers of lean mice with NASH. Forty-two potential biomarkers were identified by metabolomics analysis, leading to abnormal metabolic pathways of primary bile acid biosynthesis and fatty acid biosynthesis, which were subsequently rebalanced by GPS. A decreased Firmicutes/Bacteroidetes (F/B) ratio and disturbed BA related GM profiles were revealed in lean mice with NASH but were partially recovered by GPS. Furthermore, serum profiling of 23 BAs confirmed that serum BA levels were elevated in the lean model but downregulated by GPS treatment. Pearson correlation analysis validated associations between BA profiles, serum biochemical indices and related GM. qPCR and Western blotting analysis further elucidated the regulation of genes associated with liver lipid synthesis and bile acid metabolism. CONCLUSIONS GPS may ameliorate steatosis in lean mice with NASH, regulating the metabolomic profile, BA metabolism, fatty acid biosynthesis, and BA-related GM. All these factors may contribute to its beneficial effect.

[PMID: 38917754 DOI: 10.1016/j.biopha.2024.116952] [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: 05/01/2024] [Revised: 06/10/2024] [Accepted: 06/15/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND Non-alcoholic steatohepatitis (NASH) and liver fibrosis are progressive conditions associated with non-alcoholic fatty liver disease (NAFLD), characterized by hepatocyte pyroptosis and hepatic stellate cell (HSC) activation. Gentiopicroside (GPS) has emerged as a potential treatment for NASH, yet its underlying mechanism remains unclear. AIM To confirm that GPS can improve NASH and liver fibrosis by blocking the NLRP3 signaling pathway STUDY DESIGN: Initially, different animal models were used to study the effects and mechanisms of GPS on NASH and fibrosis. Subsequent in vitro experiments utilized co-cultures and other techniques to delve deeper into its mechanism, followed by validation of the findings in mouse liver tissues. METHODS C57BL/6 mice were fed high-fat, high-cholesterol (HFHC), or methionine-choline-deficient (MCD) diets to induce NASH and fibrosis. RAW264.7 cells and born marrow bone marrow-derived macrophages (BMDMs) were stimulated with LPS and ATP to induce inflammation, then co-cultured with primary hepatocytes and HSCs, treated with GPS, and its efficacy and mechanism were analyzed. RESULTS In vivo, GPS alleviated NASH and liver fibrosis by inhibiting the NLRP3 pathway. In vitro, GPS attenuated inflammation induced by BMDMs by inhibiting TLR4 and NLRP3 signaling pathways, and Co-culture studies suggested that GPS reduced hepatocyte pyroptosis and HSC activation, which was also confirmed in liver tissues CONCLUSION: GPS improves NASH and liver fibrosis by inhibiting the TLR4 and NLRP3 signaling pathways. The specific mechanism may be related to the suppression of macrophage-mediated inflammatory responses, thereby reducing hepatocyte pyroptosis and HSC activation.

Inflammation 2024:10.1007/s10753-024-02060-z. [PMID: 38874810 DOI: 10.1007/s10753-024-02060-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/08/2024] [Accepted: 05/21/2024] [Indexed: 06/15/2024]
Abstract
Previous studies have verified that celastrol (Cel) protects against rheumatoid arthritis (RA) by inhibiting the NLRP3 inflammasome signaling pathway, but the molecular mechanism by which Cel regulates NLRP3 has not been clarified. This study explored the specific mechanisms of Cel in vitro and in vivo. A type II collagen-induced arthritis (CIA) mouse model was used to study the antiarthritic activity of Cel; analysis of paw swelling, determination of the arthritis score, and pathological examinations were performed. The antiproliferative and antimigratory effects of Cel on TNF-α induced fibroblast-like synoviocytes (FLSs) were tested. Proinflammatory factors were evaluated using enzyme-linked immunosorbent assay (ELISA). The expression of NF-κB/NLRP3 pathway components was determined by western blotting and immunofluorescence staining in vitro and in vivo. The putative binding sites between Cel and Hsp90 were predicted through molecular docking, and the binding interactions were determined using the Octet RED96 system and coimmunoprecipitation. Cel decreased arthritis severity and reduced TNF-α-induced FLSs migration and proliferation. Additionally, Cel inhibited NF-κB/NLRP3 signaling pathway activation, reactive oxygen species (ROS) production, and proinflammatory cytokine secretion. Furthermore, Cel interacted directly with Hsp90 and blocked the interaction between Hsp90 and NLRP3 in FLSs. Our findings revealed that Cel regulates NLRP3 inflammasome signaling pathways both in vivo and in vitro. These effects are induced through FLSs inhibition of the proliferation and migration by blocking the interaction between Hsp90 and NLRP3.

Abstract
Antibiotic related intestinal injury in early life affects subsequent health and susceptibility. Here, we employed weaned piglets as a model to investigate the protective effects of baicalin against early-life antibiotic exposure-induced microbial dysbiosis. Piglets exposed to lincomycin showed a marked reduction in body weight (p < 0.05) and deterioration of jejunum intestinal morphology, alongside an increase in antibiotic-resistant bacteria such as Staphylococcus, Dolosicoccus, Escherichia-Shigella, and Raoultella. In contrast, baicalin treatment resulted in body weights, intestinal morphology, and microbial profiles that closely resembled those of the control group (p > 0.05), with a significant increase in norank_f_Muribaculaceae and Prevotellaceae_NK3B31_group colonization compared with lincomycin group (p < 0.05). Further analysis through fecal microbial transplantation into mice revealed that lincomycin exposure led to significant alterations in intestinal morphology and microbial composition, notably increasing harmful microbes and decreasing beneficial ones such as norank_Muribaculaceae and Akkermansia (p < 0.05). This shift was associated with an increase in harmful metabolites and disruption of the calcium signaling pathway gene expression. Conversely, baicalin supplementation not only counteracted these effects but also enhanced beneficial metabolites and regulated genes within the MAPK signaling pathway (MAP3K11, MAP4K2, MAPK7, MAPK13) and calcium channel proteins (ORA13, CACNA1S, CACNA1F and CACNG8), suggesting a mechanism through which baicalin mitigates antibiotic-induced intestinal and microbial disturbances. These findings highlight baicalin's potential as a plant extract-based intervention for preventing antibiotic-related intestinal injury and offer new targets for therapeutic strategies.

Abstract
OBJECTIVE To investigate the inhibitory effect of Celastrus orbiculatus extracts (COE) on the proliferation of lymphoma cells and the immune regulation ability on inflammation and thrombophilia in vivo. METHODS The 38B9 lymphoma cells were treated with COE (160 µ g/mL) and CTX (25 µ mol/L). The apoptosis rate and cell cycle of each group were detected by flow cytometry. The secretion of inflammatory factors, including interleukin (IL)-6, IL-10, and tumor necrosis factor α (TNF-α), in cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA). In vivo, BALB/c mice were subcutaneously injected with 38B9 lymphoma cells to establish lymphoma model. COE (3 mg·kg-1·d-1) and CTX (40 mg·kg-1·d-1) were administered to the model mice, respectively. The expression of plasma inflammatory factors (IL-6, IL-10 and TNF-α) and thrombus indexes, including D-dimer (D-D), von Willebrand factor (vWF) and tissue factor (TF), were detected by ELISA before tumor bearing (1 d), after tumor formation (14 d) and after intervention (21 d). PicoGreen dsDNA was used to detect the level of serum neutrophil extracellular traps (NETs). Flow cytometry was used to detect the expression of platelet activation marker calcium-dependent lectin-like receptor 2 (CLEC-2). The tumor growth and survival of mice were recorded. RESULTS The 38B9 lymphoma cells were apoptotic after the intervention of COE and CTX. The ratio of G2-M phase cells decreased in COE intervented cells compared with the control cells (P<0.05), and S phase cells decreased in CTX intervented cells (P<0.05). Also, the secretion level of IL-6 was significantly reduced after COE or CTX intervention (P<0.05), and IL-10 was significantly increased (P<0.05). Furthermore, the tumor mass was reduced, and the median survival time was longer in COE and CTX intervented tumor-bearing mice than in non-intervented mice. The significantly lower levels of TNF-α, IL-6, NETs, TF, DD and CLEC-2, as well as higher IL-10 were observed in COE and CTX treatment mice in comparision with the control mice (P<0.05). CONCLUSION COE has a mild and stable anti-tumor effect, which can reduce the secretion of inflammatory factors by lymphoma cells and regulate thrombophilic state caused by tumor inflammatory microenvironment.

Mechanisms of NLRP3 inflammasome in rheumatoid arthritis and osteoarthritis and the effects of traditional Chinese medicine. JOURNAL OF ETHNOPHARMACOLOGY 2024; 321:117432. [PMID: 37992880 DOI: 10.1016/j.jep.2023.117432] [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: 06/10/2023] [Revised: 11/06/2023] [Accepted: 11/13/2023] [Indexed: 11/24/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE It has been widely reported that various anti-rheumatic traditional Chinese medicines (TCMs) ameliorate rheumatoid arthritis (RA) and osteoarthritis (OA) through regulating the abnormal production, assembly, and activation of the NOD-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome. These TCMs include monomers isolated from Chinese herbs, extracts of Chinese herbs, and Chinese medical formulae with a lengthy application history. AIM OF THE STUDY This review aimed to summarize and analyze the published articles about the NLRP3 inflammasome and its role in the pathogenesis of RA and OA. We also reviewed existing knowledge on the therapeutic mechanism of TCMs in RA and OA via the regulation of the NLRP3 inflammasome. MATERIALS AND METHODS We searched for relevant articles with the keywords "NLRP3 inflammasome", "traditional Chinese medicine," "Chinese herbal drugs," "rheumatoid arthritis," and "osteoarthritis." The information retrieval was conducted in medical Chinese and English databases from the date of construction to April 19, 2023, including PubMed, MEDLINE, Web of Science, Scopus, Ovid, China National Knowledge Infrastructure (CNKI), Chinese Biomedicine Literature Database (CBM), Chinese Science and Technology Periodicals Database (VIP), and China Online Journals (COJ). RESULTS According to retrieval results, 35 TCMs have been demonstrated to relieve RA by targeting the NLRP3 inflammasome, including six traditional Chinese prescriptions, seven extracts of Chinese herbs, and 22 monomers extracted from traditional Chinese herbs and formulae. Additionally, 23 TCMs have shown anti-OA effects with abilities to modulate the NLRP3 inflammasome, including five traditional Chinese prescriptions, one extract of Chinese herbs, and 17 monomers from Chinese herbs. CONCLUSIONS We summarized mechanism research about the pivotal roles of the NLRP3 inflammasome in the pathogenesis of RA and OA. Moreover, a review of TCMs with targets of the NLRP3 inflammasome in RA and OA treatment was also conducted. Our work is conducive to a better application of TCMs in complementary and alternative therapies in RA and OA.

Abstract
Gentiopicroside (GPS), a single compound isolated from Gentiana lutea L. and the crucial representative of secoiridoid constituent, has been permitted for centuries in traditional Chinese medicine. GPS and its metabolites have been increasingly used in the search for clinical management with therapeutic properties and fewer side effects. The objective of this review was to provide a comprehensive overview of the involvement of molecular pathways in the therapeutic effects of GPS on human diseases and chronic conditions. This study presents a meticulously conducted comprehensive search of the PubMed and Google Scholar databases (from 1983 to 2023), aimed at identifying articles relating to regulatory mechanisms of GPS on human diseases and the pharmacokinetics of GPS. The inclusion criteria were meticulously and precisely defined to encompass original research papers that explicitly focused on elucidating the regulatory mechanisms of GPS in various human diseases through in vitro and animal studies. Notably, these studies were mandated to integrate specific genetic markers or pathways as essential components of their research inquiries. The evaluated pharmacokinetic parameters included maximum plasma concentration (Cmax), time to reach maximum plasma concentration (Tmax), area under the curve (AUC), clearance, and plasma half-life (t1/2). Subsequently, through a rigorous screening process of titles and abstracts, studies conducted in vitro or on animals, as well as those reporting pharmacokinetic data related to drugs other than GPS or language barriers, were systematically excluded. Drawing from the data and studies pertaining to this review, we conducted a thorough and informative analysis of the pharmacological characteristics and biological functions of GPS. These encompassed a wide range of effects, including hepatoprotective, anti-inflammatory, antifibrotic, antioxidant, analgesic, antitumor, and immunomodulatory properties. The analysis provided a comprehensive and insightful understanding of GPS's pharmacological profile and its diverse activities. Enhancing theoretical and experimental methodologies could prove advantageous in expanding the clinical applications of GPS. This could involve optimizing the bioavailability and pharmacokinetics of GPS, uncovering additional biomarkers and potential biotransformation pathways, and investigating its combined effects with standard-of-care medications.

Abstract
Ten lignans, including six previously undescribed phenolic ester glycosyl lignans (1-6), were isolated from a well-known traditional Chinese medicine, Qin-Jiao, which is the dry root of Gentiana macrophylla Pall. (Gentianaceae). Their structures were determined by spectroscopic and chemical methods, especially 2D NMR techniques. Quantum chemical calculations of theoretical ECD spectra allowed the determination of their absolute configurations. Refer to its traditional applications for the treatment of rheumatic arthralgia and hepatopathy, these compounds were evaluated on a TNF-α induced MH7A human synoviocyte inflammation model and a D-GalN induced AML12 hepatocyte injury model. Compounds 1, 2, 5, and 6 significantly reduced the release of proinflammatory cytokine IL-1β in MH7A cells at 15 μM and they also could strongly protect AML12 cells against D-GalN injury at 30 μM. Flow cytometry and Western blot analysis showed that compound 5 ameliorated D-GalN induced AML12 cell apoptosis by upregulating the expression of anti-apoptotic Bcl-2 protein and down-regulating the expression of pro-apoptotic Bax protein.

Abstract
Gentianae Macrophyllae Radix (GMR) is a traditional Chinese herb with the function of dispelling wind and dampness, and removing damp heat. Currently, it is reported in the literature that GMR mainly contains iridoids and secoiridoids, in addition to triterpenoids, flavonoids, lignans, steroids, alkaloids and other chemical components. Among them, iridoids and secoiridoids are the main active ingredients of GMR. Modern pharmacological studies have shown that GMR has pharmacological effects such as anti-inflammatory, anti-tumor, hepatoprotective, immunomodulatory and cardioprotective. In clinical practice, GMR is mainly used to treat rheumatoid arthritis, ulcerative colitis, stroke and other related diseases with good therapeutic effects. Currently, there are few literature reports on the GMR research progress. Therefore, this paper provides a review of the chemical composition, pharmacological activity and clinical applications of GMR to provide some scientific basis for the further development of plant resources.

Abstract
Four previously undescribed terpenoid glucosides, including one sesquiterpenoid di-glucoside (1), two new iridoid glucosides (2, 3), and a new triterpenoid tri-glucoside (4), were isolated from a 70% ethanol extract of the root of Gentiana macrophylla (Gentianaceae), along with eight known terpenoids. Their structures were determined by spectroscopic techniques, including 1D, 2D NMR, and HRMS (ESI), as well as chemical methods. The absolute configuration of compound 1 was determined by quantum chemical calculation of its theoretical electronic circular dichroism (ECD) spectrum. The sugar moieties of all the new compounds were confirmed to be D-glucose by GC analysis after acid hydrolysis and acetylation. Anti-pulmonary inflammation activity of the iridoids were evaluated on a TNF-α induced inflammation model in A549 cells. Compound 2 could significantly alleviate the release of proinflammatory cytokines IL-1β and IL-8 and increase the expression of anti-inflammatory cytokine IL-10.

Abstract
BACKGROUND Rheumatoid arthritis (RA), is a typical autoimmune disease affecting nearly 1% of the world's population. The dysfunctional hyperproliferation of synovial fibroblast (SF) in articular cartilage of RA patients is considered as the essential etiology. Traditional chemotherapeutic agents for RA treatment are imperfect for their high cost and unpredictable side-effects. L. ruthenicum anthocyanins (LRAC) is a natural product that of potential for therapeutic application against RA. METHODS LRAC was characterized by UPLC-MS/MS. Bioinformatics analyses based on network pharmacology were applied to predict the potential targets of LRAC, and to select DEGs (differentially expressed genes) caused by RA pathogenesis from GSE77298. Interactions between LRAC and the predicted targets were evaluated by molecular docking. Effects of LRAC on SFs from RA patients were examined by in vitro assays, which were analyzed by flow cytometry and western blotting (WB). RESULTS LRAC was able to inhibit the abnormal proliferation and aggressive invasion of SFs from RA patients. LRAC was mainly constituted by petunidin (82.7%), with small amount of delphinidin (12.9%) and malvidin (4.4%) in terms of anthocyanidin. Bioinformatics analyses showed that in 3738 RA-related DEGs, 58 of them were collectively targeted by delphinidin, malvidin and delphinidin. AR, CDK2, CHEK1, HIF1A, CXCR4, MMP2 and MMP9, the seven hub genes constructed a central network mediating the signal transduction. Molecular docking confirmed the high affinities between the LRAC ligands and the protein receptors encoded by the hub genes. The in vitro assays validated that LRAC repressed the growth of RASF by cell cycle arresting and cell invasion paralyzing (c-Myc/p21/CDK2), initiating cell apoptosis (HIF-1α/CXCR4/Bax/Bcl-2), and inducing pyroptosis via ROS-dependent pathway (NOX4/ROS/NLRP3/IL-1β/Caspase-1). CONCLUSION LRAC can selectively inhibit the proliferation of RASFs, without side-effecting immunosuppression that usually occurred for RA treatment using MTX (methotrexate). These findings demonstrate the potential application of LRAC as a phytomedicine for RA treatment, and provide a valid approach for exploring natural remedies against autoimmune diseases.

Fractionated whole body γ-irradiation aggravates arthritic severity via boosting NLRP3 and RANKL expression in adjuvant-induced arthritis model: the mitigative potential of ebselen. Inflammopharmacology 2023:10.1007/s10787-023-01238-5. [PMID: 37131046 DOI: 10.1007/s10787-023-01238-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Accepted: 04/16/2023] [Indexed: 05/04/2023]
Abstract
Rheumatoid arthritis (RA) is an autoimmune chronic inflammatory disease associated with oxidative stress that causes excruciating pain, discomfort, and joint destruction. Ebselen (EB), a synthesized versatile organo-selenium compound, protects cells from reactive oxygen species (ROS)-induced injury by mimicking glutathione peroxidase (GPx) action. This study aimed to investigate the antioxidant and anti-inflammatory effects of EB in an arthritic irradiated model. This goal was achieved by subjecting adjuvant-induced arthritis (AIA) rats to fractionated whole body γ-irradiation (2 Gy/fraction once per week for 3 consecutive weeks, for a total dose of 6 Gy) and treating them with EB (20 mg/kg/day, p.o) or methotrexate (MTX; 0.05 mg/kg; twice/week, i.p) as a reference anti-RA drug. The arthritic clinical signs, oxidative stress and antioxidant biomarkers, inflammatory response, expression of NOD-like receptor protein-3 (NLRP-3) inflammasome, receptor activator of nuclear factor κB ligand (RANKL), nuclear factor-κB (NF-κB), apoptotic indicators (caspase 1 and caspase 3), cartilage integrity marker (collagen-II), and histopathological examination of ankle joints were assessed. EB notably improved the severity of arthritic clinical signs, alleviated joint histopathological lesions, modulated oxidative stress and inflammation in serum and synovium, as well as reduced NLRP-3, RANKL, and caspase3 expression while boosting collagen-II expression in the ankle joints of arthritic and arthritic irradiated rats with comparable potency to MTX. Our findings suggest that EB, through its antioxidant and anti-inflammatory properties, has anti-arthritic and radioprotective properties in an arthritic irradiated model.

Int Immunopharmacol 2023; 119:110231. [PMID: 37130441 DOI: 10.1016/j.intimp.2023.110231] [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: 03/22/2023] [Revised: 04/19/2023] [Accepted: 04/20/2023] [Indexed: 05/04/2023]
Abstract
Macrophage polarization is decisive for homeostasis maintenance and tissue repair. Anti-inflammatory properties of curcumin (CUR) have been demonstrated in several studies. It used in the treatment of bone disorders includingrheumatoid arthritis. The present study aims to explore the potential mechanisms of curcumin on macrophage polarization, expression, activation, and cytokine secretion in adjuvant-induced arthritis as well as its possible role in enhancing the therapeutic action of methotrexate (MTX) together with minimizing MTX initiated side-effects. Rats were divided into eight groups as follows; Control group, MTX group: was weekly injected with MTX, CUR group: was treated with a daily oral dose of curcumin, MTX + CUR group: was treated with both methotrexate and curcumin, Adjuvant arthritis group (AIA): was injected with complete Freund's adjuvant for arthritis induction, AIA/MTX group: arthritic rats treated with methotrexate, AIA/CUR group: arthritic rats treated with curcumin and AIA/MTX + CUR: arthritic rats treated with both methotrexate and curcumin. Paw swelling, haematological analysis, immunological studies, histological observations and quantitative immunohistochemical investigations were performed. The present results showed that treating arthritic rats with curcumin either alone or in combination with methotrexate resulted in amelioration in paws inflammation, growth rate, absolute and relative spleen weights, and haematological analyses. Antinuclear antibodies, IL-1β, IL-8, IL-10, NF-kB levels, and CD68 + joint expression were also ameliorated. The microscopic examination of joint and spleen showed more improvement as apparently normal tissues in treated groups. It can be concluded that curcumin seems to be most promising in regulating macrophage expression, activation, cytokine secretion, and polarization, thus providing a novel insight in the application of curcumin-based treatments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euphorbium is the resinous secretion of Euphorbia resinifera Berg. According to the record, Euphorbium was first used by Roman doctors to treat the emperor's joint pain. In China, it is applied in folk medicine to treat damp-cold or mucous diseases, such as arthralgia and ascites, etc. This herb is used for rheumatoid arthritis and skin tumors in the folklore of northeastern Brazil. Triterpenes are mainly characteristic constituents of Euphorbium, and possibly possess anti-rheumatoid arthritis. AIM OF THE STUDY To explore the preventive effect of Euphorbium total triterpenes (TTE) on Freund's complete adjuvant (FCA) induced arthritis in rats and its mechanism. MATERIAL AND METHODS TTE was extracted and isolated from Euphorbium, and its components were analyzed by HPLC. The safety of TTE was evaluated by an acute toxicity test in mice. Arthritis was induced in rats by injecting 0.2 mL FCA into the right hind paw toe, except for the control group, which was given the same volume of physiological saline. Tripterygium Glycosides (TG, 7.5 mg/kg) and TTE (32, 64 and 128 mg/kg) were administered by gavage for 30 days. Body weights, paw swelling, and arthritic scores were measured during the experiment process. After 30 days, blood and joints were harvested to determine various indicators of arthritis. RESULTS The contents of euphol and euphorbol in TTE were 47.03% and 18.77% respectively, and the maximal feasible dose of TTE in mice is 12 g/kg. The experimental results showed that arthritis indicators in rats deteriorated after FCA inducement compared with the control group. After treatment with TTE, the swelling degree and histopathological change of the hind paws in rats were significantly improved as well as arthritic score; the serum TNF-α, CRP, IL-1β, IL-6, IL-18 and RF levels in rats were significantly reduced; The expression of PI3K, AKT, P-AKT, Bcl-2, NF-κB, NLRP3 and Pro-caspase-1 protein in joint tissue were down-regulated, and the expression of Bax protein was up-regulated. CONCLUSION The results suggested that TTE possessed anti-arthritis effects, and its mechanism may be related to its anti-inflammatory and immunomodulatory properties, as well as regulation of PI3K/AKT/Bax and NF-κB/NLRP3 signaling pathway.

Phytochemistry, Pharmacology and Molecular Mechanisms of Herbal Bioactive Compounds for Sickness Behaviour. Metabolites 2022; 12:metabo12121215. [PMID: 36557252 PMCID: PMC9782141 DOI: 10.3390/metabo12121215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 11/24/2022] [Accepted: 11/25/2022] [Indexed: 12/07/2022] Open
Abstract
The host's response to acute infections or tissue injury is a sophisticated and coordinated adaptive modification called sickness behaviour. Many herbs have been studied for their ability to protect animals against experimentally induced sickness behaviour. However, there is a lack of knowledge and experimental evidence on the use of herbal bioactive compounds (HBACs) in the management of sick behaviour. The goal of this review is to provide a concise summary of the protective benefits and putative mechanisms of action of phytochemicals on the reduction of lipopolysaccharide (LPS)-induced sickness behaviour. Relevant studies were gathered from the search engines Scopus, ScienceDirect, PubMed, Google Scholar, and other scientific databases (between 2000 and to date). The keywords used for the search included "Lipopolysaccharide" OR "LPS" OR "Sickness behaviour" OR "Sickness" AND "Bioactive compounds" OR "Herbal medicine" OR "Herbal drug" OR "Natural products" OR "Isolated compounds". A total of 41 published articles that represented data on the effect of HBACs in LPS-induced sickness behaviour were reviewed and summarised systemically. There were 33 studies that were conducted in mice and 8 studies in rats. A total of 34 HBACs have had their effects against LPS-induced changes in behaviour and biochemistry investigated. In this review, we examined 34 herbal bioactive components that have been tested in animal models to see if they can fight LPS-induced sickness behaviour. Future research should concentrate on the efficacy, safety, and dosage needed to protect against illness behaviour in humans, because there is a critical shortage of data in this area.

Investigation of the mechanism of Isobavachalcone in treating rheumatoid arthritis through a combination strategy of network pharmacology and experimental verification. JOURNAL OF ETHNOPHARMACOLOGY 2022; 294:115342. [PMID: 35525528 DOI: 10.1016/j.jep.2022.115342] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 03/12/2022] [Accepted: 05/01/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Isobavachalcone (IBC) is a natural chalcone compound widely distributed in traditional Chinese medicine Psoralea corylifolia L., and Tibetan medicine Abelmoschus manihot (L.) Medik. Etc.. Among them, Psoralea corylifolia has the effect of tonifying the kidney and strengthening Yang, and it is recorded in the Medicinal theory that it can be used in managing rheumatism and arthralgia. In addition, It has been included in many prescriptions in traditional Chinese medicine as the main herb for managing rheumatoid arthritis (RA). Similarly, Abelmoschus manihot is a common Tibetan medicinal herb and is a common medicinal material in Tibetan medicine and reported in ancient medicinal books such as Jing Zhu Ben Cao and Si Bu Yi Dian to possess the effect of Ganhuangshui and thus can be used in treating Huangshui diseases (such as RA). Previous research has demonstrated IBC to possess numerous biological activities, including anti-cancer, anti-inflammatory, antibacterial and immunomodulatory. Nevertheless, its efficacy and potential mechanism in treating rheumatoid arthritis are yet to be investigated. AIM OF THE STUDY This study aimed at investigating the therapeutic efficacy and mechanism of IBC in treating RA through a combined strategy of network pharmacology, in vitro, and in vivo evaluation. MATERIALS AND METHODS The Swiss Target Prediction and GeneCards databases were consulted to predict the potential targets of IBC and RA. Additionally, the potential targets for IBC in treating RA were predicted by consulting databases such as String, Cytoscape, MCODE, and Cytohubba. R software was utilized for enrichment analysis of GO and KEGG pathways, followed by in vitro experimentation using cell lines and in vivo experimentation using animals to explore the potential mechanism of IBC in RA treatment. RESULTS By integrating the results of network pharmacological analysis, 17 genes were found to be strongly associated with RA, such as TNF, MAPK13, EGFR, PTGS2, MMP3, etc. The enrichment analysis indicated that IBC possessed tremendous therapeutic efficacy in managing RA through PI3K-AKT, rheumatoid arthritis, and TNF signaling pathways. The in vitro experimentation indicated that IBC inhibited the proliferation, migration, and invasion, and promoted apoptosis and inhibition of inflammation of MH7A cell lines stimulated with TNF-α. The IBC might also have an increasing effect on the intracellular ROS and reducing effect on the mitochondrial membrane potential. The western blotting results indicated that IBC markedly inhibited the expression of p-PI3K, p-AKT, p-JAK1, p-STAT3 and SOCS3 proteins in TNF-α stimulated MH7A cells. Furthermore, we found that IBC also significantly reduced paw swelling and arthritis severity in CIA model rats through in vivo animal studies. CONCLUSIONS In short, this study explored the effect of IBC by combining network pharmacology prediction with in vitro and in vivo experimentation. The results indicated that IBC exerts its anti-rheumatoid arthritis effect by regulating cell proliferation and survival via PI3K/AKT and JAK/STAT signaling pathways. This may open a new horizon and provide a theoretical foundation for further development and utilization of IBC in RA management.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease involving joints, with clinical manifestations of joint inflammation, bone damage and cartilage destruction, joint dysfunction and deformity, and extra-articular organ damage. As an important source of new drug molecules, natural medicines have many advantages, such as a wide range of biological effects and small toxic and side effects. They have become a hot spot for the vast number of researchers to study various diseases and develop therapeutic drugs. In recent years, the research of natural medicines in the treatment of RA has made remarkable achievements. These natural medicines mainly include flavonoids, polyphenols, alkaloids, glycosides and terpenes. Among them, resveratrol, icariin, epigallocatechin-3-gallate, ginsenoside, sinomenine, paeoniflorin, triptolide and paeoniflorin are star natural medicines for the treatment of RA. Its mechanism of treating RA mainly involves these aspects: anti-inflammation, anti-oxidation, immune regulation, pro-apoptosis, inhibition of angiogenesis, inhibition of osteoclastogenesis, inhibition of fibroblast-like synovial cell proliferation, migration and invasion. This review summarizes natural medicines with potential therapeutic effects on RA and briefly discusses their mechanisms of action against RA.

Abstract
Control of excessive mitochondrial oxidative stress could provide new targets for both preventive and therapeutic interventions in the treatment of chronic inflammation or any pathology that develops under an inflammatory scenario, such as rheumatoid arthritis (RA). Increasing evidence has demonstrated the role of mitochondrial alterations in autoimmune diseases mainly due to the interplay between metabolism and innate immunity, but also in the modulation of inflammatory response of resident cells, such as synoviocytes. Thus, mitochondrial dysfunction derived from several danger signals could activate tricarboxylic acid (TCA) disruption, thereby favoring a vicious cycle of oxidative/mitochondrial stress. Mitochondrial dysfunction can act through modulating innate immunity via redox-sensitive inflammatory pathways or direct activation of the inflammasome. Besides, mitochondria also have a central role in regulating cell death, which is deeply altered in RA. Additionally, multiple evidence suggests that pathological processes in RA can be shaped by epigenetic mechanisms and that in turn, mitochondria are involved in epigenetic regulation. Finally, we will discuss about the involvement of some dietary components in the onset and progression of RA.

Abstract
Rheumatoid arthritis (RA) is a systemic chronic disease characterized by inflammation and synovitis. More effective treatment methods with less side effects need to be developed. In this context, current study investigated the therapeutic effects of safranal in a model of complete Freund's adjuvant (CFA)-induced RA. The control group was given 1 ml of saline orally starting from the 8th day, and 0.2 ml of CFA was given to the RA, RA + Safranal and RA + Methotrexate (MTX) groups on the 0th day of the experiment. Starting from the 8th day of the experiment, 1 ml of saline was given to the RA group, safranal was given at 200 mg/kg of body weight to the RA + MTX group, and 3 mg/kg of MTX to the RA + MTX group twice a week. The results showed that weight gain decreased in the RA group compared to the control group while arthritis index score, thymus index, and planter temperature were found to be increased. Additionally, a deterioration in blood parameters, an increase in alanine aminotransferase, aspartate aminotransferase, urea, creatinine, C-reactive protein, and malondialdehyde levels, and a decrease in reduced glutathione levels and glutathione peroxidase and catalase (CAT) activities were seen while tumor necrosis factor-α, interleukin-6 (IL-6), cyclooxygenase-2, nuclear factor kappa B levels were found to be increased. However, the safranal had a regulatory effect on all the values, except IL-6 and CAT, and blood parameters. Moreover, histopathological examination revealed that safranal reduced inflammatory cell infiltration and edema.

Abstract
OBJECTIVE Over the years, microRNAs (miRNAs) have been involved in the pathogenesis of rheumatoid arthritis (RA). We aim to investigate the role of human umbilical cord mesenchymal stem cells (HUCMSCs)-derived exosomal miR-140-3p in RA development. METHODS Exosomes(exo) were isolated from human umbilical cord-derived mesenchymal stem cells (HUCMSCs), and this isolation was followed by the transfer of miR-140-3p. RA rat models were constructed by collagen II adjuvant and respectively treated with HUCMSCs-exo or HUCMSCs-exo carrying miR-140-3p mimic/inhibitor, and expression of miR-140-3p and serum- and glucocorticoid-inducible kinase 1 (SGK1) was assessed. Then, RA score and inflammation scoring, fibrosis degree and apoptosis, serum inflammatory response and oxidative stress in joint tissues were determined. The RA synovial fibroblasts (RASFs) were extracted from rats and identified. Conducted with relative treatment, the migration, proliferation and apoptosis in RASFs were determined. RESULTS MiR-140-3p was decreased while SGK1 was increased in RA rats. HUCMSCs-exo or upregulated exosomal miR-140-3p improved pathological changes and suppressed inflammation, oxidative stress and fibrosis in RA rats, and also constrained and RASF growth. Overexpression of SGK1 reversed the inhibition of RASF growth caused by overexpression of miR-140-3p. CONCLUSION Upregulated exosomal miR-140-3p attenuated joint injury of RA rats by silencing SGK1. This research provided further understanding of the role of exosomal miR-140-3p in RA development.

Abstract
In the last several decades, apoptosis interference has been considered clinically irrelevant in the context of renal injury. Recent discovery of programmed necrotic cell death, including necroptosis, ferroptosis, and pyroptosis refreshed our understanding of the role of cell death in kidney disease. Pyroptosis is characterized by a lytic pro- inflammatory type of cell death resulting from gasdermin-induced membrane permeabilization via activation of inflammatory caspases and inflammasomes. The danger-associated molecular patterns (DAMPs), alarmins and pro-inflammatory cytokines are released from pyroptotic cells in an uncontrolled manner, which provoke inflammation, resulting in secondary organ or tissue injuries. The caspases and inflammasome activation-related proteins and pore-forming effector proteins known as GSDMD and GSDME have been implicated in a variety of acute and chronic microbial and non-microbial kidney diseases. Here, we review the recent advances in pathological mechanisms of pyroptosis in kidney disease and highlight the potential therapeutic strategies in future.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease with challenging therapeutic potential due to the implication of cross-talking intracellular pathways in the pathogenesis of the disease. This study aimed to evaluate the effects of the combination therapy of atorvastatin and quercetin on glycogen synthase kinase-3 beta/ nuclear factor kappa-B/ nucleotide-binding oligomerization domain-like receptor family pyrin domain containing-3 or inflammasome (GSK-3β/NF-KB/NLRP-3) pathway as well as on microRNAs 26b and 20a (miR-26b, miR-20a) and to investigate the possible beneficial outcomes of the combination to offer a better treatment option than methotrexate (MTX) in adjuvant-induced arthritis (AIA). Assessment of arthritis progression, serum inflammatory, and oxidative parameters were done. The tibiotarsal tissue expression of the inflammatory parameters was evaluated. Western blot analysis was done to assess the expression level of the important members in the GSK-3β/NF-κB/NLRP-3 pathway. Furthermore, the expression level of both microRNAs and serum level of transaminases were determined. All treatments, especially the combination regimen, abated arthritis progression, the elevated serum level of inflammatory and oxidative stress parameters in arthritic rats. Moreover, They down-regulated the gene expression of the important members of the aforementioned signaling pathway, amended the tissue levels of inflammatory parameters and elevated the expression level of miR-26b and miR-20a. Finally, we concluded that the combination therapy modulated miR-26b and miR-20a as well as GSK-3β/NF-κB/NLRP-3 pathway, provided additive anti-inflammatory and anti-oxidant effects and offered an additional hepatoprotective effect as compared to untreated arthritic rats and MTX-treated groups, suggesting its promising role to be used as replacement therapy to MTX in RA.

Abstract
Acute gouty arthritis is a self-limiting inflammatory disease resulting from the deposition of monosodium urate (MSU) crystals. It has been shown that Gentiopicroside (GPS) possesses anti-inflammatory and analgesic functions. The aim of this study was to parse out whether GPS has an effect on acute gouty arthritis. We established an acute gouty arthritis model by the injection of MSU into the paw, and found that GPS relieves MSU-induced mechanical, thermal hyperalgesia, and paw swelling. Furthermore, GPS down-regulated the release of pro-inflammatory cytokines in paw tissues, including IL-1β, IL-6, IL-18, and TNF-α. The results of H&E staining and MPO activity measurement showed that GPS inhibits neutrophil infiltration. And the over-expressions of NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), and Caspase-1 induced by MSU were inhibited by treatment with GPS. These results revealed that GPS can treat acute gouty arthritis based on anti-inflammatory and analgesic properties in vivo, which might be ascribed to the inhibition on NLRP3 inflammasome. Furthermore, we performed in vitro study to confirm the results of in vivo study. Consistently, the results proved that GPS could inhibit the activation of NLRP3 inflammasome in RAW264.7 macrophages stimulated by LPS-MSU. In conclusion, this study provides an experimental basis for the application of GPS and expands the potential value of GPS in the therapy of acute gouty arthritis.

Abstract
In the pathogenesis of rheumatoid arthritis (RA), rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) have tumor-like characteristics, mainly manifested by hyperproliferation and resistance to apoptosis and then it will erode the bone and cartilage, eventually leading to joint destruction. Paris saponin VII (PS VII) is an active compound derived from a traditional herbal medicine named Trillium tschonoskii Maxim, which has anti-tumor, analgesic, and immunomodulatory effects. However, its anti-RA effect has not yet been reported. This study was to investigate the effect of PS VII on two rheumatoid arthritis fibroblast-like synoviocytes lines (RA-FLS and MH7A) and adjuvant-induced arthritis (AIA) in rats. In vitro, the effects of PS VII on the proliferation, cell cycle, and apoptosis of RA-FLS and MH7A cells were detected by MTT, flow cytometry, and western blot analysis. In vivo, the effect of PS VII on the weight of the rat, paw swelling, ankle joint diameter, arthritis index, serum inflammatory cytokines (TNF-α, IL-6, and IL-1β), histopathological assessment and apoptosis proteins in the synovial tissues were evaluated in AIA rats. The in vitro studies showed that PS VII inhibited the proliferation of RA-FLS and MH7A cells, induced S phase arrest and triggered cell apoptosis mainly through the mitochondrial apoptotic pathway and the regulation of JNK and p38 MAPK pathways. The in vivo studies revealed that PS VII could improve ameliorate body weight, paw swelling, ankle joint diameter, reduce the spleen and thymus index, suppress the production of TNF-α, IL-6 and IL-1β, improve histopathological changes and regulate the expressions of apoptosis proteins in AIA Rats. In conclusion, PS VII could inhibit the proliferation and trigger apoptosis of RA-FLS and MH7A cells by regulating the mitochondrial apoptosis pathway and the JNK and p38 MAPK pathways, and alleviate the symptoms of RA, signifying it to be one of the potential anti-RA therapeutics.

Abstract
Background: Mycobacterium vaccae vaccine, a composition of Mycobacterium proteins, has been known to have bidirectional immunomodulatory functions. Recent studies have shown that M. vaccae has a therapeutic potential for treating asthma. However, little is known regarding the effect of M. vaccae aerosol inhalation during allergen sensitization or challenge on asthma. The purpose of this study was to explore the effect and the underlying mechanism of M. vaccae aerosol inhalation during allergen sensitization or challenge on airway inflammation in an asthma mouse model. Methods: Asthma mouse models were established. Mice received aerosol inhalation with M. vaccae once daily during allergen sensitization or challenge for 5 days successively. Airway responsiveness, bronchoalveolar lavage fluid (BALF) cell count, histology, and cytokine concentrations (IL-4, IFN-γ, IL-10, and IL-17) were measured. The relative mRNA expression of ASC, caspase-1, TNF-α, and IL-1β was also determined. Expression of pulmonary NLRP3 and nuclear factor kappa B (NF-κB) protein was measured using immunohistochemistry and Western blot. Results: M. vaccae aerosol inhalation suppressed airway hyperresponsiveness and inflammation, reduced levels of IL-4, upregulated expression of IFN-γ and IL-10 in BALF, inhibited mRNA expression of pulmonary ASC, caspase-1, TNF-α, and IL-1β, and also inhibited expression of pulmonary NLRP3 and NF-κB protein during allergen sensitization or challenge. Conclusion: M. vaccae aerosol inhalation can suppress airway hyperresponsiveness and inflammation during allergen sensitization or challenge, and may be a promising approach for asthma therapy.

Abstract
Anti-inflammatory potential of orally administrated bioflavonoid-robinin, active sub-stance of original drug Flaroninum™ (FL), was investigated in the combination with methotrexate (MTX) and in monotherapy in rats suffering from adjuvant-induced arthritis (AA). Robinin (kaempferol-3-O-robinoside-7-O-rhamnoside) was isolated from the aerial parts of Astragalus falcatus Lam. The monotherapy with robinin was not efficient in alleviating symptoms of AA. The combination of MTX with robinin was similarly active as MTX alone in reducing the hind paw volume and change of body weight during the whole experiment. The combination, however, reduced plasma levels of Interleukin-17Aand activity of gamma-glutamyl transferase in joint more efficiently then MTX alone. Our results demonstrate that the novel combination of robinin and MTX mildly improved the reduction of inflammation in experimental arthritis.

Abstract
Rheumatoid arthritis (RA) is featured by a variety of physical symptoms and fibroblast-like synoviocytes (FLSs) abnormal proliferation. Increasing evidence has demonstrated that traditional Chinese medicine exerts an important role in RA treatment. New bitongling (NBTL) as one of the traditional Chinese medicine has been reported to be involved in the progression of RA, but the exact mechanism is unclear. In our study, we intended to investigate the effect of NBTL on RA to identify the mechanisms related to JAK2/STAT3 signaling pathway. Extracts of Tripterygium wilfordii (TW), a traditional Chinese herbal medicine, have been widely used for treating RA in China for several decades, so, TW was used as a positive control drug for TBNL. RA rats were constructed by immunization with collagen type II to evaluate the action of NBTL in vivo. Body weight and arthritic index were evaluated. Hematoxylin and Eosin staining was performed to analysis the morphological changes of ankle joints tissue. TUNEL and flow cytometry were performed to examine cell apoptosis, while CCK8 and Ethynyl-2'-deoxyuridine (EdU) were performed to examine cell proliferation. In addition, the markers of inflammation were detected by Western blot, ELISA, and RT-qPCR. Firstly, we find that rats treated with NBTL or TW not only reduced swelling degree and bone destruction, but also repressed IL-1 β and IL-6 levels. In addition, NBTL and TW could increase the weight of rats, and promote the level of IL-10 and IL-4 in vivo. Furthermore, NBTL inhibited inflammation of FLS, induced cell apoptosis and hindered cell proliferation, which was reversed by dipeptidyl peptidase (DPP), a JAK2/STAT3 pathway activator. Taken together, NBTL potentially retarded RA via JAK2/STAT3 pathway, highlighting novel mechanisms associated with RA.

Abstract
Koumine (KM), one of the primary constituents of Gelsemium elegans, has been used for the treatment of inflammatory diseases such as rheumatoid arthritis, but whether KM impacts the activation of the NOD-like receptor protein 3 (NLRP3) inflammasome remains unknown. This study aimed to explore the inhibitory effect of KM on NLRP3 inflammasome activation and the underlying mechanisms both in vitro using macrophages stimulated with LPS plus ATP, nigericin or monosodium urate (MSU) crystals and in vivo using an MSU-induced peritonitis model. We found that KM dose-dependently inhibited IL-1β secretion in macrophages after NLRP3 inflammasome activators stimulation. Furthermore, KM treatment efficiently attenuated the infiltration of neutrophils and suppressed IL-1β production in mice with MSU-induced peritonitis. These results indicated that KM inhibited NLRP3 inflammasome activation, and consistent with this finding, KM effectively inhibited caspase-1 activation, mature IL-1β secretion, NLRP3 formation and pro-IL-1β expression in LPS-primed macrophages treated with ATP, nigericin or MSU. The mechanistic study showed that, KM exerted a potent inhibitory effect on the NLRP3 priming step, which decreased the phosphorylation of IκBα and p65, the nuclear localization of p65, and the secretion of TNF-α and IL-6. Moreover, the assembly of NLRP3 was also interrupted by KM. KM blocked apoptosis-associated speck-like protein containing a CARD (ASC) speck formation and its oligomerization and hampered the NLRP3-ASC interaction. This suppression was attributed to the ability of KM to inhibit the production of reactive oxygen species (ROS). In support of this finding, the inhibitory effect of KM on ROS production was completely counteracted by H2O2, an ROS promoter. Our results provide the first indication that KM exerts an inhibitory effect on NLRP3 inflammasome activation associated with blocking the ROS/NF-κB/NLRP3 signal axis. KM might have potential clinical application in the treatment of NLRP3 inflammasome-related diseases.

Mol Pain 2021; 17:17448069211041847. [PMID: 34433333 PMCID: PMC8404669 DOI: 10.1177/17448069211041847] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 06/08/2021] [Accepted: 08/07/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND It has been increasingly reported that microRNAs (miRNAs) are related to rheumatoid arthritis (RA) pathogenesis. This present research was conducted to analyze the functions of miR-137 and the underlying molecular mechanism in RA progression. METHODS Differentially expressed miRNAs in RA patients were analyzed using microarray-based analyses. Next, experiments involving miR-137 overexpression were performed to analyze the role of miR-137 in human fibroblast-like synoviocytes-RA (HFLS-RA) using cell counting kit-8 (CCK-8) assay, EdU staining, Transwell assay and flow cytometry, respectively. The function of miR-137 in inflammation was determined using ELISA. The binding relationship between miR-137 and LSD1 was confirmed by dual-luciferase reporter gene assay and ChIP test. Besides, a rat model with RA was established for in vivo experiments. RESULTS miR-137 was downregulated in RA tissues and cells, which was negatively correlated with inflammatory factors. Upregulated miR-137 suppressed growth, migration and invasion of HFLS-RA, but promoted apoptosis. Lysine-specific demethylase-1 (LSD1) was a target of miR-137 and could be negatively regulated by miR-137. Moreover, LSD1 could activate REST through demethylation, while the REST/mTOR pathway induced levels of pro-inflammatory factors in RA. We observed the similar results in our in vivo study. CONCLUSION This study suggested that miR-137 reduced LSD1 expression to inhibit the activation of REST/mTOR pathway, thus preventing against inflammation and ameliorating RA development. Our research may offer new insights into treatment of RA.

Abstract
Continuous stimulation of inflammation is harmful to tissues of an organism. Inflammatory mediators not only have an effect on metabolic and inflammatory bone diseases but also have an adverse effect on certain genetic and periodontal diseases associated with bone destruction. Inflammatory factors promote vascular calcification in various diseases. Vascular calcification is a pathological process similar to bone development, and vascular diseases play an important role in the loss of bone homeostasis. The NLRP3 inflammasome is an essential component of the natural immune system. It can recognize pathogen-related molecular patterns or host-derived dangerous signaling molecules, recruit, and activate the pro-inflammatory protease caspase-1. Activated caspase-1 cleaves the precursors of IL-1β and IL-18 to produce corresponding mature cytokines or recognizes and cleaves GSDMD to mediate cell pyroptosis. In this review, we discuss the role of NLRP3 inflammasome in bone diseases and vascular calcification caused by sterile or non-sterile inflammation and explore potential treatments to prevent bone loss.
