摘要:


文题释义:

类风湿关节炎:是一种慢性的自身免疫疾病,其特征是以小关节为主的关节炎症及周围组织的疼痛和肿胀,常与其他类风湿疾病,如系统性红斑狼疮和类风湿性心脏病等合并发生。随病情加重可逐步导致关节软骨破坏、关节畸形,严重影响患者的日常生活及生活质量。
分子对接技术:是一种用于确定药物分子与靶分子之间相互作用的方法。目前可研究中草药活性成分与生物靶点的相互作用,有助于揭示中草药的药理作用机制,如研究中药抗癌、抗炎和抗病毒活性的分子机制,并为中草药的药效预测、质量标准和药物设计提供依据。


背景:临床上补骨脂-淫羊藿治疗类风湿关节炎疗效明显,但两者所含有效成分复杂,在分子水平上治疗类风湿关节炎的作用机制仍不明确。

目的:基于网络药理学和分子对接技术建立胶原诱导型关节炎模型,验证补骨脂-淫羊藿治疗类风湿关节炎可能的作用靶点及通路,为以补骨脂-淫羊藿为主的临床方剂使用提供可靠的实验依据。
方法:借助中医药研究平台、中医百科全书和上海有机所的中药与化学成分数据库等检索并筛选有效成分,从PubChem平台获取3D分子式,通过PharmMapper和SwissTargetPrediction平台进行靶标预测;结合DrugBank、GeneCards、OMIM等基因数据库完成类风湿关节炎的疾病靶点获取,经Uniport数据库校准靶标,借助VENNY 2.1获取补骨脂-淫羊藿与疾病交集靶点并绘制韦恩图;采用STRING平台构建蛋白质互作网络图;使用Metascape平台进行基因本体论功能分析及京都基因与基因组百科全书分析,进行数据可视化,利用Cytoscape 3.9.0构建中药-成分-靶点-疾病-通路四重网络模型;运用AutoDock-Vina软件将主要有效成分与核心靶点进行分子对接验证,探索最佳结合靶点。建立Ⅱ型胶原+佐剂诱导型关节大鼠模型,用补骨脂-淫羊藿干预21 d后,观察其对相关通路靶点及炎性细胞因子的影响。

结果与结论:①筛选补骨脂与淫羊藿活性成分28个,与类风湿关节炎交集靶点共288个,主要成分有异补骨脂素、补骨脂定、淫羊藿苷等;交集靶点主要有丝氨酸/苏氨酸蛋白激酶1(AKT1)、肿瘤坏死因子、血管内皮生长因子A等;②基因本体论分析获得生物过程2 232条,主要与丝氨酸蛋白磷酸化、AKT正调控、活性氧代谢过程等功能有关;③京都基因与基因组百科全书富集分析结果202条,主要有PI3K/AKT信号通路和表皮生长因子受体信号通路等,可能通过调节滑膜细胞凋亡与增殖、抑制炎性因子等发挥治疗作用;④分子对接结果表明补骨脂-淫羊藿主要与AKT1及雌激素受体转录因子1结合活性最强,并形成稳定结构,与PI3K/AKT等凋亡增殖、炎性介导等调控信号通路密切相关;⑤补骨脂-淫羊藿可降低胶原诱导型关节炎大鼠模型血清中白细胞介素1β、白细胞介素6、肿瘤坏死因子α的表达;⑥补骨脂-淫羊藿可调低胶原诱导型关节炎大鼠模型关节滑膜中p-PI3K、p-AKT、p-FOXO1蛋白的表达;⑦结果证明,补骨脂-淫羊藿可能经PI3K/AKT/FOXO1信号通路抑制关节滑膜细胞增殖和抑制炎性因子表达等发挥治疗作用,这可能与类风湿关节炎关节炎症和骨破坏的发生密切相关,同时为临床的合理使用及新药开发提供了参考依据。

Abstract: BACKGROUND: In clinical practice, Cibotium barometz and Epimedium have shown significant efficacy in the treatment of rheumatoid arthritis, but the complex active ingredients contained in the two have an unclear mechanism of action at the molecular level for the treatment of rheumatoid arthritis.
OBJECTIVE: Based on network pharmacology and molecular docking technology, to establish a collagen-induced arthritis model and to verify the potential targets and pathways of Cibotium barometz and Epimedium in the treatment of rheumatoid arthritis, providing reliable experimental evidence for the use of clinical formulas with Cibotium barometz and Epimedium as the main components.
METHODS: Utilizing traditional Chinese medicine research platforms, traditional Chinese medicine encyclopedias, and databases of traditional Chinese medicine and chemical components from the Shanghai Institute of Organic, effective ingredients were retrieved and identified. 3D molecular formulas were obtained from the PubChem platform and target predictions were made using PharmMapper and SwissTargetPrediction. Disease targets for rheumatoid arthritis were obtained from gene databases such as DrugBank, GeneCards, and OMIM. The intersections of targets and Cibotium barometz and Epimedium were plotted using VENNY 2.1 after calibration with the Uniport database. A protein-protein interaction network graph was constructed using the STRING platform. Gene Ontology function analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the Metascape platform for data visualization. A four-layered network model of traditional Chinese medicine, ingredients, targets, diseases, and pathways was constructed using Cytoscape 3.9.0. The main effective ingredients were docked with core targets using AutoDock-Vina software to explore the best binding targets. A type II collagen+adjuvant-induced arthritis rat model was established, and the effects of Cibotium barometz and Epimedium on relevant pathway targets and inflammatory cell factors were observed after 21 days of intervention.
RESULTS AND CONCLUSION: A total of 28 active ingredients from Cibotium barometz and Epimedium were selected, yielding 288 intersection targets for rheumatoid arthritis. The main ingredients included isobavachalcone, cibotium, and epimedium. The main targets included protein kinase 1 for serine/threonine (AKT1), tumor necrosis factor, and vascular endothelial growth factor A. Gene ontology analysis yielded 2 232 biological processes, mainly related to serine protein phosphorylation, positive regulation of serine/threonine protein kinase, and reactive oxygen metabolism. Kyoto Encyclopedia of Genes and Genomes enrichment analysis yielded 202 pathways, mainly involving the PI3K/AKT signaling pathway and epidermal growth factor receptor signaling pathway, which may exert therapeutic effects by regulating synovial cell apoptosis and proliferation and suppressing inflammatory factors. Molecular docking results showed the strongest binding activity and stable structure of Cibotium barometz and Epimedium with AKT1 and estrogen receptor transcription factor 1, which was closely related to apoptosis and proliferation and inflammatory signaling pathways such as PI3K/AKT. Cibotium barometz and Epimedium reduced the expression of interleukin-1β, interleukin-6, and tumor necrosis factor-α in the serum of collagen-induced arthritis rat models. Cibotium barometz and Epimedium reduced the expression of p-PI3K, p-AKT, and p-FOXO1 in the synovium of collagen-induced arthritis rat models. The results indicate that the combination of Cibotium barometz and Epimedium may exert therapeutic effects by inhibiting the proliferation of synovial cells and suppressing the expression of inflammatory factors via the PI3K/AKT/FOXO1 signaling pathway. This may be closely related to the occurrence of inflammation and bone destruction in rheumatoid arthritis, and provides a reference for the rational use and development of new drugs in clinical practice.
