Albiflorin inhibits osteoclastogenesis and titanium particles-induced osteolysis via inhibition of ROS accumulation and the PI3K/AKT signaling pathway. Int Immunopharmacol 2024; 142:113245. [PMID: 39340985 DOI: 10.1016/j.intimp.2024.113245] [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: 06/22/2024] [Revised: 09/18/2024] [Accepted: 09/20/2024] [Indexed: 09/30/2024]
Abstract
Periprosthetic osteolysis (PPO), caused by wear particles, is a significant complication of total joint replacement, leading to prosthesis failure. Previous research has highlighted the crucial role of osteoclast-induced bone destruction in PPO progression. Albiflorin (AF), a monoterpene glycoside from Paeonia lactiflora, is a key active ingredient known for its antioxidant and anti-inflammatory properties. Although AF has shown promise in treating various conditions, its impact on osteoclasts and PPO remains unexplored. Our study revealed that AF could effectively inhibit osteoclast differentiation to reduce overactivated bone resorption and effectively inhibit the accumulation of reactive oxygen species (ROS) induced by wear particles. In vitro experiments also confirmed that AF could effectively inhibit the PI3K/AKT signaling pathway and inhibit inflammation to regulate osteoclast generation. Studies in animal models have also verified the antioxidant and anti-inflammatory properties of AF. In summary, the above studies indicate that AF inhibits osteoclastogenesis via inhibiting ROS accumulation and the PI3K/AKT signaling pathway, which may be a potential therapeutic method for PPO.

Chen X, Liu J, Wang G, Sun Y, Ding X, Zhang X. Validation of Jianpi Qingre Tongluo Recipe in Reducing Inflammation and Dyslipidemia in Osteoarthritis via Lnc RNA HOTAIR/APN/PI3K/AKT. Int J Gen Med 2024; 17:3293-3318. [PMID: 39081673 PMCID: PMC11288358 DOI: 10.2147/ijgm.s466148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Accepted: 07/20/2024] [Indexed: 08/02/2024] Open
Abstract
Objective Jianpi Qingre Tongluo Recipe (JQP) has been widely used in clinical practice, and its anti-Osteoarthritis (OA) effectiveness and specific mechanism have been concerned. This study aims to explore the clinical effect of JQP in reducing inflammation and dyslipidemia in OA and the molecular mechanism. Methods The clinical efficacy of JQP in OA treatment was assessed through data mining. Through the network pharmacology technology, the interactive network of "active component-target-disease" was developed, the interaction relationship of the related proteins was analyzed, and enrichment analysis of gene pathway biological process was conducted. Molecular docking was carried out with PyMOL and AutodockTools-1.5.7. Finally, cell experiments were used to verify JQP's delay of immune inflammation in OA. Results We found that JQP could ameliorate the immune inflammatory and lipid metabolism indicators; reduce VAS and SAS score in OA. A total of 98 genes overlapped between target genes of JQP and OA. TNF, IL-6, IL-1β, and AKT1 shared the highest centrality among all target genes. KEGG analysis unveiled that 98 intersection genes were predominantly enriched in PI3K/AKT pathway in the anti-OA system. In vitro, after peripheral blood mononuclear cell (PBMC) stimulation, inflammatory cytokines imbalances and the expressions of adiponectin (APN) were decreased in osteoarthritis-chondrocytes (OA-CH). Furthermore, JQP-containing serum protected OA-CHs through down-regulating HOTAIR levels, thereby up-regulating APN and depressing PI3K/AKT pathway. Conclusion This study suggests that JQP might reduce inflammation and improve lipid metabolism of OA by regulating HOTAIR/APN/PI3K/AKT. Our results bring a new solution for OA.

[PMID: 38907263 PMCID: PMC11193218 DOI: 10.1186/s13018-024-04850-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Accepted: 06/13/2024] [Indexed: 06/23/2024] Open
Abstract
BACKGROUND Long non-coding RNAs (LncRNAs) are recognized as a pivotal element in the processes of fracture healing and the osteogenic differentiation of stem cells. This study investigated the molecular mechanism and regulatory significance of lncRNA MAGI2-AS3 (MAGI2-AS3) in fracture healing. METHODS Serum levels of MAGI2-AS3 in patients with normal and delayed fracture healing were verified by RT-qPCR assays. The predictive efficacy of MAGI2-AS3 for delayed fracture healing was analyzed by ROC curve. Osteogenic markers were quantified by RT-qPCR assays. MC3T3-E1 cell viability was detected using CCK-8 assay, and flow cytometry was utilized to measure cell apoptosis. The dual-luciferase reporter gene assay was used to determine the targeted binding between MAGI2-AS3 and miR-223-3p. RESULTS Serum MAGI2-AS3 expression was decreased in patients with delayed fracture healing compared with patients with normal healing. Elevated MAGI2-AS3 resulted in an upregulation of the proliferative capacity of MC3T3-E1 cells and a decrease in mortality, along with increased levels of both osteogenic markers. However, after transfection silencing MAGI2-AS3, the trend was reversed. Additionally, miR-223-3p was the downstream target of MAGI2-AS3 and was controlled by MAGI2-AS3. miR-223-3p mimic reversed the promoting effects of MAGI2-AS3 overexpression on osteogenic marker levels and cell growth, and induced cell apoptosis. CONCLUSION The upregulation of MAGI2-AS3 may expedite the healing of fracture patients by targeting miR-223-3p, offering a novel biomarker for diagnosing patients with delayed healing.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 321:117515. [PMID: 38042386 DOI: 10.1016/j.jep.2023.117515] [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: 09/23/2023] [Revised: 11/19/2023] [Accepted: 11/25/2023] [Indexed: 12/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Taohong Siwu decoction (TSD) is a classic traditional Chinese medicine (TCM) prescription used to promote the blood circulation and alleviate blood stasis. TSD consists of Paeonia lactiflora Pall., Conioselinum anthriscoides (H. Boissieu) Pimenov & Kljuykov, Rehmannia glutinosa (Gaertn.) DC., Prunus persica (L.) Batsch, Angelica sinensis (Oliv.) Diels, and Carthamus creticus L. in the ratio of 3:2:4:3:3:2. Studies on the effects of TSD on myocardial ischemia-reperfusion injury (MIRI) from the perspective of autophagy and pyroptosis have not been reported. AIM OF THE STUDY Investigate the effect of TSD on MIRI and explore the underlying mechanisms. MATERIALS AND METHODS We searched the main components and corresponding potential targets of TSD on The Pharmacology of Traditional Chinese Medicine Systems database for target prediction. We identified targets for MIRI on Online Mendelian Inheritance in Man and GeneCards databases. The intersection of the compound target and disease target was obtained and a protein-protein interaction network constructed. We undertook enrichment analyses using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases. The results of network pharmacology were verified by in vivo experiments in mice. RESULTS In mice, TSD significantly reduced the volume of the myocardial infarct, significantly reduced serum levels of cardiac troponin-nI (CTnI), creatine kinase-myocardial band (CK-MB), malonaldehyde (MDA), interleukin (IL)-6, increased the activity of superoxide dismutase (SOD) and IL-10 level, reduced the level of pyroptosis in myocardial tissue, increased the number of autophagosomes, and significantly reduced the fluorescence intensity of apoptosis-associated speck-like protein (ASC), Nod-like receptor protein 3 (NLRP3), and caspase-1. TSD administration increased the protein expression of microtubule-associated protein light chain 3 (LC3), but reduced the protein expression of p62, NLRP3, ASC, caspase-1, cleaved caspase-1, pro-caspase-1, gasdermin D (GSDMD), GSDMD-N-terminal, IL-18, and IL-1β. Administration of 3-Methyladenin could reverse the effect of TSD in inhibiting inflammation and the release of proinflammatory factors. CONCLUSION TSD treatment alleviated MIRI by promoting autophagy to suppress activation of the NLRP3 inflammasome and reducing the release of proinflammatory factors.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xinfeng capsule is a traditional Chinese medicine compound, which has been clinically used for more than 20 years in the treatment of rheumatoid arthritis (RA), ankylosing spondylitis, osteoarthritis and its extracurricular lesions. However, the molecular role of XFC in the treatment of RA remains unclear. OBJECTIVE This study aims to explore the efficacy and potential mechanism of XFC through retrospective data mining analysis, animal experiments and cell experiments. METHODS The effect of XFC on clinical laboratory indexes of RA patients was observed using data mining techniques combined with association rule analysis and a random walk model. Afterwards, a rat model of adjuvant arthritis (AA) was established with Freund's complete adjuvant, followed by the observation of pathological changes in synovial tissues and the ultrastructure of synoviocytes. A RA cell model was constructed by inducing fibroblast-like synoviocytes (FLSs) with tumor necrosis factor-alpha (TNF-α) to assess the effects of XFC-containing serum on inflammation and oxidative stress through long non-coding RNA LINC00638. RESULTS In retrospective data mining, XFC effectively reduced immune inflammation and increase the level of antioxidant enzymes in RA patients. Subsequently, animal experiments showed that XFC significantly repressed immune inflammation, oxidative stress, synovial hyperplasia, and cartilage destruction, while improving the ultrastructure of synoviocytes in AA rats. XFC-containing serum diminished the proliferation of TNF-α-induced RA-FLSs, increased LINC00638 expression (P<0.01), decreased interleukin-6 (IL-6), IL-17, reactive oxygen species (ROS) and reactive nitrogen species (RNS) levels (P<0.01), and increased the protein expression of nuclear factor erythrocyte 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), and superoxide dismutase 2 (SOD2) (P<0.01). Furthermore, rescue experiments manifested that XFC-containing serum reversed the effects of silencing LINC00638 on inflammation and oxidative stress in RA-FLSs. CONCLUSION XFC inhibits inflammation and oxidative stress in RA by up-regulating LINC00638 and activating Nrf2/HO-1 pathway.

Taohong Siwu Decoction Promotes Osteo-Angiogenesis in Fractures by Regulating the HIF-1α Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6777447. [PMID: 36193143 PMCID: PMC9526655 DOI: 10.1155/2022/6777447] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 08/02/2022] [Accepted: 08/13/2022] [Indexed: 11/17/2022]
Abstract
Background Vascular damage is a major consequence of bone fracture. Taohong Siwu decoction (TSD) can raise the expression of vascular endothelial growth factor (VEGF) in fracture healing. However, its molecular mechanism in promoting angiogenesis is still unknown. The aim of this study was to investigate the potential mechanisms of TSD in the regulation of osteo-angiogenesis in fracture healing. Methods A rat tibial fracture model was established. After low- (4.5 g·kg−1), medium- (9 g·kg−1), and high-dose TSD (18 g·kg−1) and panax notoginsenoside (25 mg kg−1) treatment, hematoxylin-eosin staining was employed to visualize pathological changes in bone tissues. The levels of cytokines (interleukin (IL)-2, tumor necrosis factor-α (TNF-α), IL-6, and IL-1β), thromboxane B2 (TXB2), and 6 ketone prostaglandin F1α (6-Keto-PGF1α) were quantified by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence was used to identify the rat aortic endothelial cells (RAECs). Control serum, 10% TSD-containing serum, and 10% TSD-containing serum combined with hypoxia-inducible factor-1α (HIF-1α) inhibitor were used to treat the RAECs and rat osteoblasts. Transwell migration assay was utilized to examine the migration of the RAECs. The Matrigel tubulogenesis assay was used for the assessment of angiogenesis. The expression of angiogenesis- (von Hippel-Lindau tumor suppressor (VHL), HIF-1α, VEGF, angiopoietin-2 (Ang-2), and pVHL) and osteogenesis-related (alkaline phosphatase (ALP), runt-related transcription factor 2 (Runx2), and osteopontin-1 (OPN-1)) protein and gene was detected by western blot and quantitative real-time PCR (qRT-PCR). Results Compared with the model group, TSD increased the trabecular bone areas, numbers, and thicknesses in fractured rats. In the plasma, the levels of cytokines and TXB2 in the middle- and high-dose TSD group were significantly lower than those in the model group (P < 0.01). The 6-keto-PGF1α content was increased by middle- and high-dose TSD intervention (P < 0.01). Compared to the control serum group, the angiogenesis and migration of the RAECs were enhanced in the TSD group (P < 0.001). The expression of HIF-1α, VEGF, and Ang-2 in the TSD group upregulated significantly (P < 0.001). VHL and pVHL were inhibited under TSD-containing serum treatment (P < 0.001). ALP, Runx2, and OPN-1 were increased obviously in the TSD group (P < 0.001). Nevertheless, the HIF-1α inhibitor reversed these changes (P < 0.001). Conclusion TSD promotes angiogenesis and osteogenesis by regulating the HIF-1α signaling pathway. Meanwhile, it can effectively reduce the risk of inflammation and improve blood circulation.

Abstract
AIMS This study aimed to explore the effect of Taohong Siwu Decoction (THSWD) on Bone marrow mesenchymal stem cells (BMSCs) at the cellular level and the possible mechanism of systemic regulation of gut microbiota on fracture recovery. METHODS AND RESULTS Cell Counting Kit-8 (CCK-8) experiments show that THSWD effectively promotes the proliferation of BMSCs. Transwell and wound healing assays show that THSWD effectively promotes the invasion and migration of BMSCs. Alizarin red staining showed that the THSWD model enhanced the osteogenic differentiation of BMSCs. Moreover, the effect of THSWD on BMSCs is time- and concentration-dependent. RT-qPCR and Western blot results showed that THSWD treatment up-regulated the expression of vascular endothelial growth factor (VEGF) and focal adhesion kinase (FAK) at mRNA and protein levels, respectively. Hematoxylin-eosin and crocin O-quick green staining showed that rats with right femoral shaft fractures, after 14 days of THSWD treatment, the area of callus and cartilage regeneration at the fracture site increased significantly. Gut microbiota was changed in fractured rats, such as the abundance of Bacteroidetes and Firmicutes was increased. THSWD showed positive regulation of both to a certain extent. CONCLUSION THSWD up-regulates VEGF and activates the FAK signaling pathway to enhance the development and differentiation of BMSCs, and systematically regulates the gut microbiota to promote fracture healing. SIGNIFICANCE AND IMPACT OF STUDY This study provides new insights on the cellular and systemic level to understand the mechanism of THSWD in the treatment of fractures.
