Int Immunopharmacol 2024; 127:111406. [PMID: 38142643 DOI: 10.1016/j.intimp.2023.111406] [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: 10/04/2023] [Revised: 12/07/2023] [Accepted: 12/14/2023] [Indexed: 12/26/2023]
Abstract
Osteoarthritis (OA) causes severe and functional dysfunction due to abnormal inflammation. The objective of this study was to evaluate the effect of Harpagide (HPG) on TNF-α-induced inflammation in vitro and in vivo. The effect of HPG on the proliferation of rat chondrocytes was studied. The anti-inflammatory effect of HPG and its molecular mechanisms were elucidated by qPCR, Western blotting, flow cytometry, metabolome analysis in vitro. In addition, the OA rat model was established, and the effect of HPG on OA was verified in vivo. We revealed 10 μM HPG demonstrated biocompatibility. The results demonstrated that HPG restored the upregulation of MMP-13, COX2, IL-1β and IL-6 induced by TNF-α. Moreover, HPG reversed TNF-α induced degradation of the extracellular matrix of chondrocytes. TNF-α treatment induced down-regulation of the mRNA/protein levels of proliferative markers Bcl2, CDK1 and Cyclin D1 were also recovered. HPG can inhibit TNF-α-induced inflammatory response through glycolytic metabolic pathways. HPG can restore TNF-α-induced upregulation of GRP78/IRE1α, and downregulation of AMPK proteins. In vivo experiments demonstrated that after HPG treatment, the appearance and physiological structure of articular cartilage were more integrated with highly organized chondrocytes and rich cartilage matrix compared with OA group. Finally, the molecular docking of HPG and selected key factors in glycolysis results showed that HPG had good binding potential with PFKM, PFKP, PFKFB3, PKM, HK2, and PFKL. In conclusion, the results shown HPG protects and activates chondrocytes, inhibits TNF-α-induced inflammatory response by glycolysis pathway in rat articular chondrocytes, and plays a role in the treatment of OA.

Alpinetin Protects Chondrocytes and Exhibits Anti-Inflammatory Effects via the NF-κB/ERK Pathway for Alleviating Osteoarthritis. Inflammation 2021; 43:1742-1750.

Abstract
Osteoarthritis (OA) is a chronic degenerative joint disease which is greatly affected by the inflammatory response triggered by the NF-κB signaling pathway. Alpinetin (APT) is a natural flavonoid compound, which has been reported to have many important biological activities such as antibacterial, antitumor, and anti-inflammatory. However, the action of its effect on chondrocytes in OA has yet to be elucidated. In this study, we investigated APT's anti-inflammatory action. The effects of APT on cell viability and cytotoxicity of rat chondrocytes was investigated by CCK8. Western blotting, qRT-PCR, and immunofluorescent staining were used to elucidate the molecular mechanisms and signaling pathways of APT mediating anti-inflammatory effects on chondrocytes. An OA model was induced by destabilization of the medial meniscus (DMM) in rats, then APT was injected into the knee articular cavity to examine its anti-inflammatory effects in vivo. These results showed that APT could reduce the TNF-α-induced increase of MMP-13 and ADAMTS-5 and decrease of COL2A1 levels. APT antagonized TNF-α-induced down-regulation of BCL-2 and CDK1. Further studies have shown that APT simultaneously repressed cell nucleus translocation of p65 and the phosphorylation of IκB and activated the phosphorylation of ERK. In vivo, APT suppressed cartilage matrix degradation. In conclusion, APT appears to favorably modulate anti-inflammatory effects in chondrocytes making it a promising compound for OA treatment. Graphical Abstract Inhibitory effects of Alpinetin on TNF-α-induced NF-κB activation resulted in destruction of cartilage in rat OA chondrocytes in vitro. The TNF-α receptor were stimulated by TNF-α, activating the cytoplasmic IκBα kinases(IKKS), then IKKs will be phosphorylated, and subsequently degraded by the ubiquitin-proteasome system. NF-κB transfer to the nucleus and bind various NF-κB regulates the NF-κB recognition site in the promoter region. Which triggers the gene expression of pro-inflammatory and pro-apoptotic. However, Alpinetin could inhibits the NF-κB signaling pathway in different ways: APT inhibits IκBα phosphorylation, preventing phosphorylated ubiquitination of IκBα further. Moreover, APT blocks translocation of the activated NF-κB to the nucleus, to protect the cartilage tissue from damage.

Gene 2020; 766:145149. [PMID: 32971185 DOI: 10.1016/j.gene.2020.145149] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 09/03/2020] [Accepted: 09/11/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Crosstalk between posterior cruciate ligament fibroblasts (PCLfs) and synoviocytes (SCs) significantly modifies the homeostatic balance of the extracellular matrix (ECM) and appears to post a prominent affection for wound healing of PCL. Interleukin-1β (IL-1β) is regarded as a critical factor in acute inflammatory events during ligament injury. METHODS In order to confirm the capability of SCs the response of lysyl oxidases (LOXs) and matrix metalloproteinases (MMPs) to IL-1β, the complex cues of the joint cavity following PCL injury were simulated and the effect of IL-1β on the expression of LOXs and MMPs in PCLfs were investigated. PCLfs in both the mono- and co-culture conditions were treated with IL-1β. Cell lysates were collected from the PCLfs and LOXs and MMP-1, 2, 3 expression quantified using quantitative real-time PCR and western bolting. RESULTS The results indicated that injury alone elevated the expression of LOXs and MMP-1, 2 and 3. But IL-1β significantly decreased the LOX, LOXL1, and LOXL3 expression, and simultaneously increased MMP-1, 2 and 3 expressions in injured PCLfs. Furthermore, co-culture further suppressed LOXs, but stimulated MMP-1, 2 and 3 expressions when subjected to both mechanical injury and IL-1β treatment. This possibly suggests that a number of soluble factors are secreted that act as mediators that amplify the response of SCs. CONCLUSION The results indicated that the SCs could affect the IL-1β-induction of LOXs inhibition and MMPs accumulation, which may be the underlying mechanism of the the poor healing response following PCL injury.

Abstract
Purposes: To investigate the ability of synoviocytes (SCs) in regulating MMPs expression in the posterior cruciate ligament fibroblasts (PCLfs) after TNF-α treatment, to test whether a specific inflammation inhibitor Bay11-7082 can antagonize the expression of MMPs in PCLfs after injury. Methods: The microenvironment of knee joint cavity after PCL injury was mimicked in an in vitro co-culture system. The effects of TNF-α treatment on the expression of MMPs in PCL fibroblasts (PCLfs) were studied. The expression of MMPs mRNA and protein was detected by qRT-PCR and western blot. For the in vivo study, the Bay11-7082 inhibitor was injected into the knee joint cavity after injury, and then were performed on histological analysis. Results: In the mono-culture conditions, 6% mechanical injury upregulated the expression of MMP-2, whereas downregulated MMP-1 and -3, additionally 12% mechanical injury were upregulated all. However, in co-culture conditions, 6% and 12% both significantly increased MMPs expressions. Stretch injury and TNF-α treatment significantly upregulated expression of MMPs mRNA and protein levels in mono-cultured PCLfs. This effect was more significant in PCLfs Plus SCs co-culture system, in which the cells were treated by combination of stretch injury and TNF-α. In addition, Bay11-7082, a specific inflammation inhibitor, could significantly decrease the expression of MMPs induced by stretch injury and/or TNF-α treatment. Less infiltrated inflammatory cells and more integrated tissues were detected in injury PCL 2 weeks after Bay11-7082 treatment, compared to injury group. Immunofluorescent staining showed very low expression levels of MMPs in PCL of Bay11-7082-treated group, compared to the injury groups. Conclusions: SCs sever as the supporting cells that aggravate the TNF-α-induced MMPs accumulation in PCLfs. Inhibition of the expression of MMPs by Bay11-7082 is a promising way to facilitate the self-healing of PCL.

Abstract
Current study examined whether psoralen (PSO) exhibits anti-inflammatory responses, protection and activation of chondrocytes, and relieve osteoarthritis (OA). Rats chondrocytes and human synoviocytes were cultured in tumor necrosis factor-α (TNF-α) conditioned culture medium with/without PSO to test the cell morphologies and cytotoxicities in vitro. Cartilaginous extracellular matrix (ECM) and proliferative gene/protein expression levels were evaluated in chondrocytes. Meanwhile, matrix metalloproteinases (MMPs) and interleukins (ILs) gene/protein expression were analyzed in synoviocytes. SD rats of monosodium iodoacetate (MIA) induced OA model were used in order to assess the effects of PSO on attenuating degeneration of the articular cartilage in vivo. Results showed TNF-α conditioned culturing with/without PSO (1-100 µM) had no any toxicity on both the cell lines. PSO (10 µM) activated cartilaginous specific ECM expression along with up-regulation of proliferative genes at transcriptional levels. Interestingly, PSO significantly reversed TNF-α induced up-regulation of MMP13 and ILs synoviocytes in a dose-dependent manner (1 to 20 µM), while down-regulated cartilaginous ECM production. Following six weeks of PSO treatments to articular cartilage osteoarthritis, compared to MIA-induced group, the appearance and physiological structure of articular cartilage was more integrated with greatly organized chondrocytes and abundant cartilage matrix. In conclusion, PSO protects and activates chondrocytes, antagonizing the expression of MMPs and ILs secreted by synovial cells, and effectively attenuates MIA-induced OA.

Abstract
Exploring effective therapies for delaying calcific heart valve disease (CHVD) is the focus of current cardiovascular clinical and scientific research. In this study, human aortic valve interstitial cells (hVICs) were isolated from patients with CHVD. After expansion, cultured hVICs were induced with the tumor necrosis factor-alpha (TNF-α) with or without anthraquinone emodin (EMD) treatments. Cytotoxicity and flow cytometric analysis were used to assess cell growth, while Alizarin Red S staining was used to detect hVICs calcification. Furthermore, RNA-sequencing analysis was utilized to investigate changes in mRNA profiles of cells cultured in TNF-α conditioned medium with or without EMD. Western blotting and qRT-PCR analyses were used for the verification of key selected genes. Our results indicated that EMD had limited influence on hVIC morphology, whereas in a dose-dependent fashion, EMD interfered with hVIC growth under TNF-α conditioned cell culture. Additionally, hVICs treated with TNF-α plus EMD, presented a gradual decrease of positive Alizarin Red S staining, when compared with cells treated with TNF-α only. Notably, cells treated with TNF-α plus EMD showed 1874 differential expression genes (DEGs), among them, 1131 were upregulated and 743 were downregulated. These DEGs displayed an enrichment of biological functions and signaling pathways, among them, BMP2, RELA, TNF, and TRAF1, were found to be significantly suppressed by EMD and selected given their role in mediating hVIC calcification. In conclusion, our study shows that EMD inhibits TNF-α-induced calcification and phenotypical transformation of hVICs via the NF-κB signaling pathway, thereby preventing calcification events stimulated during acute inflammatory responses.
