Resveratrol is a natural polyphenol in lots of foods and traditional Chinese medicines, which has shown promising treatment for neurodegenerative diseases (NDs). However, the molecular mechanisms of its action have not been systematically studied yet. In order to elucidate the network pharmacological prospective effects of resveratrol on NDs, we assessed of pharmacokinetics (PK) properties of resveratrol, studied target prediction and network analysis, and discussed interacting pathways using a network pharmacology method. Main PK properties of resveratrol were acquired. A total of 13,612 genes related to NDs, and 138 overlapping genes were determined through matching the 175 potential targets of resveratrol with disease-associated genes. Gene Ontology (GO) function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed to obtain more in-depth understanding of resveratrol on NDs. Accordingly, nodes with high degrees were obtained according using a PPI network, and AKT1, TP53, IL6, CASP3, VEGFA, TNF, MYC, MAPK3, MAPK8, and ALB were identified as hub target genes, which showed better affinity with resveratrol in silico studies. In addition, our experimental results demonstrated that resveratrol markedly enhanced the decreased levels of Bcl-2 and significantly reduced the increased expression of Bax and Caspase-3 in hippocampal neurons induced by glutamate exposure. Western blot results confirmed that resveratrol inhibited glutamate-induced apoptosis of hippocampal neurons partly by regulating the PI3K/AKT/mTOR pathway. In conclusion, we found that resveratrol could target multiple pathways forming a systematic network with pharmacological effects.
白藜芦醇是许多食物和传统中药中的一种天然多酚,已显示出对神经退行性疾病(NDs)有良好的治疗前景。然而,其作用的分子机制尚未得到系统研究。为了阐明白藜芦醇对NDs的网络药理学潜在作用,我们评估了白藜芦醇的药代动力学(PK)特性,研究了靶点预测和网络分析,并使用网络药理学方法探讨了相互作用途径。获得了白藜芦醇的主要PK特性。通过将白藜芦醇的175个潜在靶点与疾病相关基因进行匹配,确定了总共13612个与NDs相关的基因和138个重叠基因。进行了基因本体论(GO)功能分析和京都基因与基因组百科全书(KEGG)通路富集分析,以更深入地了解白藜芦醇对NDs的作用。因此,使用蛋白质-蛋白质相互作用(PPI)网络获得了高度节点,并将AKT1、TP53、IL6、Casp3、VEGFA、TNF、MYC、MAPK3、MAPK8和ALB确定为枢纽靶基因,这些基因在计算机模拟研究中显示出与白藜芦醇有更好的亲和力。此外,我们的实验结果表明,白藜芦醇显著提高了谷氨酸暴露诱导的海马神经元中Bcl-2降低的水平,并显著降低了Bax和Caspase-3增加的表达。蛋白质免疫印迹结果证实,白藜芦醇部分通过调节PI3K/AKT/mTOR通路抑制谷氨酸诱导的海马神经元凋亡。总之,我们发现白藜芦醇可以靶向多个途径,形成一个具有药理作用的系统网络。
