Abstract
Background: Allergic asthma is an inflammatory disease of the airways that causes great distress to the patient's normal life. Astragalus Polysaccharide (APS) is the main active ingredient in the traditional Chinese medicine Astragalus mongholicus Bunge, which has the effect of regulating immune function.
Objective: This study aimed to evaluate the effect of APS on allergic asthma and investigate its potential mechanism of action.
Methods: This study utilized network pharmacology to predict the relevant targets and signaling pathways of APS treatment for allergic asthma. Subsequently, an animal model was established using Ovalbumin (OVA) induction. The efficacy of APS was verified using histopathologic staining and Airway Hyperresponsiveness (AHR) assay. Signaling pathways were examined using Western Blot (WB). Finally, bioinformatics analysis was utilized to explore the correlation between the progression of allergic asthma and signaling pathways.
Results: Network pharmacology analysis identified 15 intersection targets significantly enriched in the PI3K/AKT signaling pathway. The results of molecular docking showed that small molecule drugs have a strong binding ability to target proteins. The experiments confirmed APS successfully suppressed the pathological symptoms in allergic asthma model mice. Subsequently, WB provided evidence supporting that APS has potential therapeutic effects mediated through the PI3K/AKT signaling pathway. The bioinformatics results confirmed that disease progression in allergic asthma patients does correlate with the PI3K/AKT signaling pathway.
Conclusion: Our study suggests that APS may treat allergic asthma by targeting the PI3K/AKT signaling pathway. This provides a basis for preliminary research on the clinical application of APS for treating allergic asthma.
背景:过敏性哮喘是一种严重影响患者正常生活的气道炎症性疾病。黄芪多糖(Astragalus polysaccharides, APS)是中药黄芪的主要活性成分,具有调节免疫功能的作用。目的:评价黄芪多糖对变应性哮喘的治疗作用,探讨其可能的作用机制。方法:利用网络药理学方法预测黄芪多糖治疗过敏性哮喘的相关靶点和信号通路。随后,采用卵清蛋白(OVA)诱导建立动物模型。采用组织病理学染色和气道高反应性(AHR)试验验证黄芪多糖的疗效。采用Western Blot (WB)检测信号通路。最后,利用生物信息学分析探讨变应性哮喘进展与信号通路的相关性。结果:网络药理学分析发现15个交叉靶点在PI3K/AKT信号通路中显著富集。分子对接结果表明,小分子药物对靶蛋白具有很强的结合能力。实验证实黄芪多糖成功抑制了变应性哮喘模型小鼠的病理症状。随后,WB提供的证据支持APS通过PI3K/AKT信号通路介导具有潜在的治疗作用。生物信息学结果证实过敏性哮喘患者的疾病进展确实与PI3K/AKT信号通路相关。结论:本研究提示黄芪多糖可能通过靶向PI3K/AKT信号通路治疗变应性哮喘。为黄芪多糖治疗过敏性哮喘临床应用的初步研究奠定了基础。
