摘要:

本研究旨在探究小檗碱(berberine,BBR)抗金黄色葡萄球菌(Staphylococcus aureusS. aureus)感染的作用靶点及分子机制。首先基于网络药理学筛选BBR与S. aureus感染的共同靶点;构建PPI网络并进行GO/KEGG富集分析;通过分子对接验证BBR与核心靶点的结合活性;通过构建小鼠感染模型,利用组织切片观察肝脏和脾脏的病理变化,并通过qPCR验证筛选靶标基因的mRNA的表达量。结果表明:1)成功筛选出BBR与S. aureus之间共有109个交集靶点,通过网络药理学的分析最终获得了251个GO条目和62个KEGG条目,主要富集在MAPK、PI3K-Akt、GnRH等通路上,分子对接结果显示,BBR与交集靶点中Casp3和Jun等6个蛋白具有较好的结合能;2)BBR可缓解S. aureus的感染引起的肝脏组织病变;同时可显著上调小鼠肝脏中Casp3 mRNA的转录量,Jun mRNA的转录量。综上所述,本研究初步筛选出BBR发挥抗S. aureus的潜在靶点为Casp3和Jun,同时构建S. aureus感染小鼠模型,进一步证实BBR可通过调控Casp3和Jun的mRNA转录,缓解肝和脾的病变,本研究结果为BBR抗S. aureus感染药物的开发和应用提供理论依据。

Abstract:

The aim of this study was to investigate the target and and molecular mechanism of action of berberine (BBR) against Staphylococcus aureusS. aureus) infection. This experiment first screened common targets of BBR and S. aureus infection based on network pharmacology, constructed a PPI network, and performed GO/KEGG enrichment analysis. The binding activity of BBR and core targets was verified through molecular docking. Finally, a mouse infection model was constructed to observe pathological changes in the liver and spleen using tissue sections, and qPCR was used to validate the expression levels of the selected target genes’ mRNA. The results showed that: 1) A total of 109 common target points between BBR and S. aureus were successfully screened. Through network pharmacology analysis, 251 GO entries and 62 KEGG entries were ultimately obtained, mainly enriched in the MAPK, PI3K-Akt, and GnRH pathways. Molecular docking results showed that BBR had good binding energy with six proteins, including Casp3 and Jun, among the intersection targets. 2) BBR can alleviate liver tissue lesions caused by S. aureus infection; at the same time, it can significantly upregulate the expression of Casp3 mRNA and Jun mRNA in mouse liver. In summary, this study preliminarily identified Casp3 and Jun as potential targets for BBR’s anti-S. aureus activity. Additionally, a mouse model of S. aureus infection was established to further confirm that BBR can alleviate liver and spleen lesions by regulating the mRNA expression of Casp3 and Jun. The findings of this study provide a theoretical basis for the development and application of BBR as an anti-S. aureus infection drug.
