摘要:
目的 探讨益骨汤防治骨质疏松的物质基础及其靶标,阐明益骨汤防治骨质疏松症的潜在靶点和作用机制。 方法 通过TCMSP等数据库筛选益骨汤组分中的活性成分及其作用靶点。通过OMIM、GeneCards等数据库预测益骨汤治疗骨质疏松症的相关靶点,构建“药物-成分-靶点-疾病”网络。利用Cytoscape软件构建益骨汤组分治疗骨质疏松症的成分作用靶点网络,采用STRING数据库构建PPI网络,利用通过生物学信息注释数据库分析靶点的GO富集和KEGG信号通路。 结果 共纳入益骨汤6味中药相关的有效活性成分159个,589个药物靶标,按照君臣佐使配对,其中334个靶点有相互作用关系;蛋白互作分析提示INS、AKT1、IL6、MAPK3、VEGFA等为蛋白互作网络中的核心靶点;靶标富集结果显示3 148个GO术语被显著富集(均P < 0.05);PI3K-Akt信号通路、MAPK信号通路、cGMP-PKG信号通路、Wnt信号通路、破骨细胞分化等175个信号通路被显著富集(均P < 0.05)。 结论 中药复方君臣佐使配伍可以转换为靶标相互作用的化合物形式,阐明益骨汤的物质基础及配伍机制。益骨汤组分靶标和通路不仅具有调节成骨细胞和破骨细胞功能的双重作用,还通过影响和干预骨微循环境,体现补肾健脾活血法治疗骨质疏松的物质基础,符合骨质疏松的病理生理机制。 Abstract:Objective To investigate the molecular basis of Yigu Decoction (YGD) and its predictive targets and clarify the potential targets and mechanisms of YGD in the treatment of osteoporosis. Methods The active components and their targets corresponding to the herbs by traditional Chinese medicine systems pharmacology database (TCMSP) were determined via network pharmacology. The relevant targets of YGD in the treatment of osteoporosis were predicted using OMIM and GeneCards databases. A network of 'drug component-target disease' was constructed. A component-based target network for the treatment of osteoporosis with YGD components was constructed using Cytoscape software. A protein-protein interaction (PPI) network was constructed using STRING database. Gene Ontology (GO) enrichment and KEGG signalling pathways of the targets were analysed using a biological information annotation database. Results A total of 159 effective active components and 589 drug targets related to six herbs were found in YGD. Protein interaction analysis suggested that INS, AKT1, IL6, MAPK3 and VEGFA were the core targets of protein interaction network. A total of 334 targets were retrieved according to their orders, which were further enriched in 3 148 GO terms (all P < 0.05). A total of 175 signalling pathways were significantly enriched (all P < 0.05), including the PI3K-Akt signalling pathway, the MAPK signalling pathway, the cGMP-PKG signalling pathway, the Wnt signalling pathway and osteoclast differentiation. Conclusion The herbs, compounds and targets related to the compounds of YGD are effective carriers for YGD according to their orders. The targets and pathways of YGD not only regulate the functions of osteoblasts and osteoclasts but also intervene in bone microcirculation, which reflect the material basis of the treatment of osteoporosis by Bushen Jianpi Huoxue and conforms to the pathophysiological mechanism of osteoporosis. -
