摘要:目的:通过网络药理学联合实验验证探讨当归黄芪超滤物(RAS-AM)治疗放射性心肌纤维化(RIMF)可能的作用靶点和机制。方法:使用TC-MSP数据库、TCM@TAIWAN台湾中医药资料库和TCMID中医药数据库筛选RAS-AM的成分和靶点,并使用Swiss Target Prediction数据库进行靶点预测。从GeneCards和OMIM数据库获得RIMF疾病靶点,疾病和药物的交集靶点通过韦恩在线工具获得,交集靶点通过STRING数据库获得蛋白互作关系(PPI),使用Cytoscape3.9.1软件构建“药物-成分-靶点-疾病”的可视化网络拓扑关系图。通过David数据库对核心靶点进行GO和KEGG富集分析,利用微生信平台作图。实验验证:将60只Wi-star大鼠随机分为空白组、模型组、阳性药物组(1.0mg/kg)、RAS-AM低剂量组(150mg/kg)、RAS-AM中剂量组(300 mg/kg)、RAS-AM高剂量组(600 mg/kg),采用38Gy剂量辐射诱导建立RIMF模型,灌胃给药4周,同时观察大鼠一般情况。大鼠取血和心脏后,HE染色观察心肌组织形态学改变,ELISA法和Western blot法检测网络药理学预测的关键靶点。结果:网络药理学分析得到RAS-AM活性成分34个,靶点705个,共有靶点154个,以IL-6、VEGFA、MMP-2、MMP-9、ACE为前五的核心靶点;GO富集分析共筛选出153个条目,KEGG富集有25条通路。实验部分:HE染色结果显示各用药组心肌细胞变性、坏死好转,心肌间质中炎症细胞浸润减轻,心肌间质纤维结缔组织增生减少。ELISA与Westernblot结果显示,与空白组比较,模型组IL-6、VEGFA、MMP-9表达均升高(P<0.05,P<0.01);与模型组比较,各用药组IL-6、VEGFA、MMP-9表达均不同程度降低(P<0.05),呈剂量依赖性。结论:RAS-AM;可能通过下调IL-6、VEGFA蛋白、MMP-9蛋白等为代表的核心靶点和调控炎症通路、胶原分解等过程,多途径协同以抗RIMF。
AIM:To explore the potential targets and mechanisms of Angelica sinensis and Astraga-lus membranaceus ultrafiltration(RAS-AM)in the treatment of radiation induced myocardial fibrosis(RIMF)through network pharmacology combined experimental validation.METHODS:Using the TC-MSP database TCM@TAIWAN The Taiwan Tradition-al Chinese Medicine Database and TCMID Tradition-al Chinese Medicine Database screen the compo-nents and targets of RAS-AM,and use the Swiss Target Prediction database for target prediction.Obtain RIMF disease targets from Gene Cards and OMIM databases,obtain intersection targets of dis-eases and drugs through Wayne's online tool,ob-tain protein interaction relationships(PPIs)through STRING database,and use Cytoscape 3.9.1 soft-ware to construct a visualized network topology di-agram of"drug component target disease".Con-ways.Experimental part:HE staining results showed that the degeneration and necrosis of myo-cardial cells improved in each medication group,the infiltration of inflammatory cells in the myocar-dial interstitium decreased,and the proliferation of fibrous connective tissue in the myocardial intersti-tium decreased.ELISA and Western blot results showed that compared with the normal group,the expression of IL-6,VEGFA,and MMP-9 in the mod-el group increased.Compared with the model groupthe expression of IL-6,VEGFA,and MMP-9 in each medication group decreased to varying de-grees,in a dose-dependent manner.CONCLUSION:RAS-AM may inhibit RIMF by downregulating core targets such as IL-6,VEGFA protein,MMP-9 pro-tein,and regulating inflammatory pathways,colla-gen degradation,and other processes.
