摘要: 目的: 联合采用网络药理学和分子对接技术,预测泼尼松治疗口腔扁平苔藓(oral lichen planus, OLP)的潜在靶点和分子机制。方法: (1)结合多种数据库预测泼尼松潜在作用靶点;(2)筛选OLP 相关疾病靶点;(3)构建药物和疾病交集靶点的PPI网络;(4)筛选网络中前20个关键靶点进行GO和KEGG富集分析;(5)分子对接分析。结果: (1)从多种数据库挖掘得到189个泼尼松潜在靶点;(2)获得552个OLP相关疾病靶点;(3)从构建的PPI网络筛选获得前20个关键靶蛋白;(4)对20个关键靶点的GO分析和KEGG分析结果表明,泼尼松可能通过调节PI3K-Akt、雌激素、丙型肝炎等信号通路发挥治疗作用;(5)分子对接分析结果表明,FN1、UBC和EGFR和泼尼松有良好的结合潜力。结论: 本研究预测获得泼尼松对OLP发挥治疗作用的潜在关键靶点及分子机制,这对促进靶向药物的研发及临床应用具有重要意义。

Abstract: Objective: To explore the potential targets and molecular mechanisms of prednisone for oral lichen planus (OLP) by applying network pharmacology and molecular docking technology. Methods: (1) The potential targets of prednisone were predicted in multiple databases. (2) OLP-related targets were screened. (3) The PPI network was constructed for the intersection targets of drugs and diseases. (4) GO and KEGG enrichment analyses were performed for the top 20 targets in the PPI network. (5) Molecular docking was performed. Results: (1) A total of 189 potential targets of prednisone were obtained from various databases. (2) 552 OLP-related disease targets were found. (3) The top 20 key targets were screened from the PPI network. (4) GO and KEGG analysis of the 20 key targets indicated that prednisone may play a therapeutic role by regulating the PI3K-Akt signaling pathway, estrogen signaling pathway, hepatitis C pathway, et al. (5) Molecular docking showed that FN1, UBC, and EGFR had good binding potential with prednisone. Conclusion: The predicted potential key targets and molecular mechanisms of prednisone in treating OLP are of great significance for the development of new targeted drugs and clinical applications.
