基于网络药理学和体外实验探讨中药复方YA3D7抗阿尔茨海默病的作用机制
Exploring the mechanism of action of the traditional Chinese medicine compound YA3D7 against Alzheimer's disease based on network pharmacology and in vitro experiments
目的 运用网络药理学的方法,结合体外实验技术,探究中药复方YA3D7(川芎、当归、白术、茯苓、生姜)抗阿尔茨海默病(Alzheimer's Disease,AD)的作用机理。 方法 运用网络药理学的相关数据库和软件工具,构建疾病-药物共同基因靶点的韦恩图,并对交集基因进行京都基因与基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)富集分析及分子对接研究;体外细胞实验评估YA3D7对BV2细胞增殖能力的影响,检测YA3D7的抗氧化效能及羟自由基清除能力,并通过实时荧光定量PCR法检测M1型小胶质细胞标志物诱导型一氧化氮合酶(inducible nitric oxide synthase,iNOS)、分化簇86分子(cluster of differentiation 86,CD86)的mRNA表达情况。 结果 确定了复方YA3D7各成分与AD的130个交集靶点,KEGG富集分析结果显示,YA3D7干预AD主要与磷脂酰肌醇 3-激酶(phosphatidylinositol 3-kinase, PI3K)/蛋白激酶B(protein kinase B, Akt)、丝裂原活化蛋白激酶(mitogen-activated protein kinase, MAPK)等线粒体相关通路有关。体外细胞增殖实验结果显示,YA3D7浓度在50 μg/mL时BV2细胞增殖能力最强(P<0.05);YA3D7在不同浓度梯度下分别表现出总抗氧化能力和羟自由基清除能力的剂量依赖性增强(P<0.05);YA3D7处理显著降低了Aβ25-35诱导的BV2细胞中iNOS、CD86的表达(P<0.05)。 结论 YA3D7可通过多途径、多靶点、多通路对AD发挥干预作用,为深入探究其在干预AD中的应用提供了理论依据。
Objective This study employs network pharmacology approaches combined with in vitro experimental techniques to explore the mechanism of action of the traditional Chinese medicine compound YA3D7 (Chuanxiong, Danggui, Baizhu, Fuling, and Shengjiang) against Alzheimer's Disease (AD). Methods Using relevant databases and software tools in network pharmacology, a Venn diagram of common gene targets between the disease and the drug was constructed. Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis and molecular docking studies were performed on the intersecting genes. In vitro cell experiments were conducted to evaluate the effect of YA3D7 on the proliferation capacity of BV2 cells, detect the antioxidant efficacy and hydroxyl radical scavenging ability of YA3D7, and measure the mRNA expression levels of M1 microglial markers—inducible nitric oxide synthase (iNOS) and cluster of differentiation 86 (CD86)—by real-time fluorescent quantitative PCR. Results A total of 130 intersecting targets related to both YA3D7 components and AD were identified. KEGG enrichment analysis showed that YA3D7 for the intervention of AD was primarily associated with mitochondrial-related pathways, such as the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) pathways. In vitro cell proliferation assays confirmed that BV2 cells exhibited the highest proliferative capacity at a YA3D7 concentration of 50 μg/mL (P<0.05). YA3D7 demonstrated dose-dependent enhancement of total antioxidant capacity and hydroxyl radical scavenging ability across different concentration gradients (P<0.05). Intervention with YA3D7 significantly reduced the expression of iNOS and CD86 in Aβ25-35-induced BV2 cells (P<0.05). Conclusion YA3D7 can play an intervention role in AD through multi-pathway, multi-target, and multi-signaling mechanisms, providing a theoretical foundation for further exploration of its application in AD intervention.
