生脉注射液干预LUAD/COVID-19的生物信息学与网络药理学研究
Journal: Basic Medical Theory Research DOI: 10.12238/bmtr.v7i5.16543
Abstract
目的:基于生物信息学分析与网络药理学,探索生脉注射液(SMI)抗LUAD/COVID-19的潜在作用机制。方法:首先通过生物信息学分析发现LUAD/COVID-19患者的临床特征,包括差异表达基因(DEGs)、生存率及预后情况;随后筛选出与SMI相关基因存在差异表达交集的基因;最终运用网络药理学和分子对接技术,深入探究SMI对抗LUAD/COVID-19的主要治疗靶点及其潜在作用机制。结果:共鉴定出905个LUAD/COVID-19差异表达基因,其中包含40个具有预后意义的基因和86个与SMI存在交集的基因。富集分析显示,这86个基因与新型冠状病毒肺炎(COVID-19)、HIF-1信号通路及脂质与动脉粥样硬化等疾病存在显著相关性。通过蛋白质相互作用网络分析,我们确定了8个核心基因(GAPDH、ALB、IL6、TLR4、FOS、ACE、ERBB2和CDK4)。分子对接实验表明,排名前三的GAPDH、ALB和IL6及其对应的SMI活性成分——腺苷、3,4-二羟基苯甲酸、水杨酸、(Z,S)-茉莉酮和茉莉酮——均展现出良好的结合活性。结论:基于生物信息学和网络药理学的研究表明,SMI的GAPDH、ALB和IL6是抗LUAD/COVID-19的潜在靶点。
