J Cell Mol Med 2024; 28:e18476. [PMID: 38842136 PMCID: PMC11154837 DOI: 10.1111/jcmm.18476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 05/15/2024] [Accepted: 05/22/2024] [Indexed: 06/07/2024] Open
Abstract
Osteoarthritis (OA) is a complicated disease that involves apoptosis and mitophagy. MST1 is a pro-apoptotic factor. Hence, decreasing its expression plays an anti-apoptotic effect. This study aims to investigate the protective effect of MST1 inhibition on OA and the underlying processes. Immunofluorescence (IF) was used to detect MST1 expression in cartilage tissue. Western Blot, ELISA and IF were used to analyse the expression of inflammation, extracellular matrix (ECM) degradation, apoptosis and mitophagy-associated proteins. MST1 expression in chondrocytes was inhibited using siRNA and shRNA in vitro and in vivo. Haematoxylin-Eosin, Safranin O-Fast Green and alcian blue staining were used to evaluate the therapeutic effect of inhibiting MST1. This study discovered that the expression of MST1 was higher in OA patients. Inhibition of MST1 reduced inflammation, ECM degradation and apoptosis and enhanced mitophagy in vitro. MST1 inhibition slows OA progression in vivo. Inhibiting MST1 suppressed apoptosis, inflammation and ECM degradation via promoting Parkin-mediated mitophagy and the Nrf2-NF-κB axis. The results suggest that MST1 is a possible therapeutic target for the treatment of osteoarthritis as its inhibition delays the progression of OA through the Nrf2-NF-κB axis and mitophagy.

Oxysophoridine inhibits oxidative stress and inflammation in hepatic fibrosis via regulating Nrf2 and NF-κB pathways. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155585. [PMID: 39068811 DOI: 10.1016/j.phymed.2024.155585] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 03/28/2024] [Accepted: 04/01/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Hepatic fibrosis (HF) runs through multiple stages of liver diseases and promotes these diseases progression. Oxysophoridine (OSR), derived from Sophora alopecuroides l., is a bioactive alkaloid that has been reported to antagonize alcoholic hepatic injury. However, whether OSR suppresses HF and the mechanisms involved in Nrf2 remain unknown. PURPOSE Since the dysregulation of inflammation and oxidative stress is responsible for the excessive accumulation of extracellular matrix (ECM) and fibrosis in the liver. We hypothesized that OSR may attenuate HF by inhibiting inflammation and oxidative stress through activating Nrf2 signaling. METHODS In this study, we employed LPS-stimulated HSC-T6 cells, RAW264.7 cells, and a CCl4-induced C57BL/6 mouse fibrotic model to evaluate its suppressing inflammation and oxidative stress, as well as fibrosis. RESULTS The result showed that OSR significantly reduced α-SMA and TGF-β1 at a low dose of 10 μM in vitro and at a dose of 50 mg/kg in vivo, which is comparable to Silymarin, the only Chinese herbal active ingredient that has been marketed for anti-liver fibrosis. Moreover, OSR effectively suppressed the expression of iNOS at a dose of 10 μM and COX-2 at a dose of 40 μM, respectively. Furthermore, OSR demonstrated inhibitory effects on the IL-1β, IL-6, and TNF-α in vitro and almost extinguished cytokine storm in vivo. OSR exhibited antioxidative effects by reducing MDA and increasing GSH, thereby protecting the cell membrane against oxidative damage and reducing LDH release. Moreover, OSR effectively upregulated the protein levels of Nrf2, HO-1, and p62, but decreased p-NF-κB p65, p-IκBα, and Keap1. Alternatively, mechanisms involved in Nrf2 were verified by siNrf2 interference, siNrf2 interference revealed that the anti-fibrotic effect of OSR was attributed to its activation of Nrf2. CONCLUSION The present study provided an effective candidate for HF involved in both activation of Nrf2 and blockage of NF-κB, which has not been reported in the published work. The present study provides new insights for the identification of novel drug development for HF.

Abstract
PURPOSE This study aimed to evaluate the protective effects of gentiopicroside against lipopolysaccharide-induced chondrocyte inflammation. METHODS SW 1353 chondrosarcoma cells were stimulated with LPS (5 μg/ml) for 24 h and treated with different concentrations of gentiopicroside (GPS) for 24 h. The toxic effects of GPS on chondrocytes were determined using a CCK-8 assay and EdU staining. Western blotting, qPCR, and immunofluorescence analysis were used to examine the protective effect of GPS against the inflammatory response in chondrocytes induced by lipopolysaccharide (LPS). One-way ANOVA was used to compare the differences between the groups (significance level of 0.05). RESULTS The CCK-8 results showed that 10, 20 and 40 μM GPS had no significant toxic effects on chondrocytes; GPS effectively reduced the production of IL-1β and PGE2, reversed LPS-induced extracellular matrix degradation in cartilage by inhibiting the Stat3/Runx2 signaling pathway, and suppressed the hypertrophic transformation of SW 1353 chondrosarcoma cells. CONCLUSION Our study demonstrated that GPS significantly inhibited the LPS-induced inflammatory response and hypertrophic cellular degeneration in SW 1353 chondrosarcoma cells and is a valuable traditional Chinese medicine for the treatment of knee osteoarthritis.

Abstract
Osteoarthritis (OA) is the most common type of arthritis and is an age-related joint disease that is particularly prevalent in subjects over 65 years old. The chronic rise of senescent cells has a close correlation with age-related diseases such as OA, and the senescence-associated secretory phenotype (SASP) is implicated in OA cartilage degeneration pathogenesis. Sirtuin 6 (SIRT6) is likely to be a key senescence-related regulator. Fisetin (FST) is a natural flavonol of the flavonoid family that is recommended as a senolytic drug to extend health and lifespan. However, the potential chondroprotective effects of FST on OA rats are largely unclarified. The aim of this study is to investigate the ameliorative effects of FST on OA joint cartilage and the relationship with SIRT6 and the detailed mechanisms from anti-inflammatory and anti-senescent perspectives. Rats were subjected to destabilization of the medial meniscus (DMM) surgery as a means of inducing the experimental OA model in vivo. Chondrocytes treated with IL-1β were utilized for mimicking the OA cell model in vitro. Intra-articular injection of FST, OSS_128,167 (OSS, SIRT6 inhibitor), and MDL800 (MDL, SIRT6 agonist) in vivo or administering them in IL-1β-induced rat chondrocytes in vitro were performed in order to determine the effects FST has on OA and the link with SIRT6. This study found SIRT6 level to be negatively correlated with OA severity. SIRT6 downregulation was validated in the joint cartilages of DMM rats and IL-1β-treated chondrocytes. It was also notably demonstrated that FST can activate SIRT6. Both the administration of FST and activation of SIRT6 using MDL were found to rescue cartilage erosion, decrease extracellular matrix (ECM) degradation, prevent cartilage from apoptosis, and improve detrimental senescence-related phenotype. The alleviative effects of FST against inflammation, ECM degradation, apoptosis, and senescence in IL-1β-stimulated chondrocytes were also confirmed. SIRT6 loss occurs in articular cartilage in OA pathogenesis, which is linked to aging. FST attenuates injury-induced aging-related phenotype changes in chondrocytes through the targeting of SIRT6.
