【摘要】 目的利用系统药理学的方法探讨续断治疗骨质疏松的可能作用机制。方法使用中药系统药理学数据库(TCMSP)获得续断的药物成分,筛选活性成分,预测靶蛋白。在TTD和CTD数据库查询骨质疏松对应靶蛋白,构建药物-靶蛋白-疾病相互作用网络。借助DAVID数据库对核心靶蛋白作用通路进行分析。利用String数据库构建主要信号通路的蛋白质相互作用网络。结果获得7个续断活性成分及其63个靶蛋白,筛选到骨质疏松疾病靶蛋白118个,得到续断与骨质疏松交叉作用蛋白118个,进而富集到与细胞增殖分化及免疫功能等相关的24条信号通路,其中PI3K-AKT信号通路包含有最多数量的相关基因。String数据库分析表明AKT1、MAPK1、MAPK3在信号通路中出现的频率较高。结论续断可能主要通过AKT1、MAPK1、MAPK3影响PI3K-AKT信号通路治疗骨质疏松。更多还原

【Abstract】 Objective To explore the possible mechanism of Dipsaci Radix in the treatment of osteoporosis based on systems pharmacology method. Methods The drug components of Dipsaci Radix were obtained from TCMSP database to screen active ingredients and predict target protein. The target protein of osteoporosis was searched in the TTD and CTD database in order to build Drug-Target protein-Disease interaction Network. Then, the analysis on the role of core target protein pathways were performed by DAVID tool. The protein interaction network of primary signal pathways was built in String database. Results Seven active ingredients of Dipsaci Radix and their 63 target proteins were obtained, 118 targets of osteoporosis were selected, and 118 cross-acting proteins between Dipsaci Radix and osteoporosis were obtained. Then 24 signaling pathways related to cell proliferation and differentiation and immune function were enriched, wherein PI3 K-AKT signaling pathway contained the largest number of related genes. String database analysis showed that AKT1, MAPK1, and MAPK3 protein appeared frequently in signal pathways. Conclusion Dipsaci Radix may affect the PI3 K-AKT signaling pathway mainly through AKT1, MAPK1, and MAPK3 for the treatment of osteoporosis. This study provides a new idea for the further mechanism study on the treatment of osteoporosis of Dipsaci Radix.更多还原
