  • 摘要: 以岩青兰化学成分为基础, 生信分析筛选岩青兰改善老年糖尿病小鼠脑神经病变的关键靶点及通路, 并通过小鼠实验进行验证, 明确其作用机制。通过Gene Cards搜集神经炎症靶点, GEO数据库筛选老年糖尿病患者脑相关差异基因(DEGs); 用Venny软件得到岩青兰的核心成分靶点与神经炎症交集靶点为56个、与DEGs交集靶点31个; 通过STRING数据库构建蛋白相互作用(PPI) 网络, 利用Cytoscape软件进行PPI及药物-成分-靶点网络的可视化处理, 并通过Maximum Clique Centrality (MCC) 筛选Top10核心靶点; 用DAVID数据库进行GO (gene ontology) 功能富集和KEGG (Kyoto encyclopedia of genes and genomes) 通路分析, 发现岩青兰主要通过神经炎症相关的丝裂原活化蛋白激酶(MAPK)、核转录因子(NF-κB) 等通路蛋白改善老年糖尿病神经病变; 使用分子对接软件对核心活性成分与核心靶点进行对接发现岩青兰中的绿原酸、香叶木素、山柰酚与蛋白激酶B (AKT1)、白细胞介素-1β (IL-1β)、B淋巴细胞瘤2 (BCL2)、血红素加氧酶1 (HMOX1) 等靶点均有较好的结合活性。动物实验显示, 岩青兰可以降低小鼠血糖、血脂水平, 改善肝脏组织细胞排列紊乱, 脂肪空泡的现象, 减少血清促炎细胞因子的水平; 下调脑肿瘤坏死因子α (TNF-α)、IL-1β、Toll样受体4 (TLR4)、核NF-κB蛋白的表达, 抑制小鼠脑离子钙结合衔接分子1 (Iba-1) 的过度激活, 降低NOD样受体热蛋白结构域蛋白3 (NLRP3) 炎症小体的激活。该研究初步揭示了岩青兰对老年糖尿病脑神经病变的治疗作用可能与调控TLR4/NF-κB、抑制炎症小体等炎症信号通路有关。本实验经过沈阳药科大学伦理委员会批准(No. SYPU-IACOC-2024-1016-103)。

     

    Abstract: Through network pharmacology and molecular docking technology, combined with in vivo experiment verification through aged db/db mice, we explored the anti-neuroinflammation mechanism of Dracocephalum rupestre Hance in aging type 2 diabetes. Neuroinflammatory targets were collected through Gene Cards, and nerve related differential genes (DEGs) in elderly patients with diabetes were screened by GEO NCBI database; 56 component targets and 31 component targets were obtained by Venny 2.1.0 software from core component targets of Dracocephalum rupestre Hance between neuroinflammatory targets and DEGs; protein-protein interaction (PPI) networks were constructed using STRING database, visualize PPI and medicine-composition-target network through Cytoscape software, and the Top 10 core targets were elected using Maximum Clique Centrality (MCC); GO (gene ontology) functional enrichment and KEGG (kyoto encyclopedia of genes and genes) pathway analysis were conducted by DAVID database. It was found that the neuroprotection effect of Dracocephalum rupestre Hance mainly include alleviated aging diabetes neuroinflammation through regulated MAPK, NF-κB and other pathway proteins. Molecular docking results showed that the core active ingredients of Dracocephalum rupestre Hance, chlorogenic acid, diosmetin, and kaempferol, have good binding activity with targets AKT1, IL-1β, BCL2, and HMOX1. In vivo experiments showed that Dracocephalum rupestre Hance can reduce blood glucose and lipid levels in aging db/db mice, ameliorate the disorder of liver tissue cell arrangement and lipid vacuoles, and reduce the level of serum pro-inflammatory cytokines; down-regulate the expression of brain TNF-α, IL-1β, TLR4, and nuclear NF-κB; inhibit the overactivation of Iba-1 in mouse brain. What's more, Dracocephalum rupestre Hance could decreased the activation of NLRP3 inflammasome. This study preliminarily revealed that the therapeutic effect of Dracocephalum rupestre Hance on aging diabetes encephalopathy may be related to improve the neuroinflammatory signal pathway, such as the regulation of TLR4/NF-κB, inhibition of NLRP3 inflammasome, etc. This experiment was approved by the Medical Ethics Committee of Shenyang Pharmaceutical University (No. SYPU-IACOC-2024-1016-103).
