基于蛋白互作网络分析祛风湿药川乌的抗炎机制

炎症是风湿性疾病的重要危险因素之一。川乌是临床常用祛风湿药,具有显著抗炎作用,然其分子层面作用机制尚不清楚。为深入探索祛风湿药川乌抗炎作用的分子层面机制,该研究以川乌抗炎活性成分乌头碱、次乌头碱和新乌头碱为代表,通过数据库检索获得化合物的作用靶点及其蛋白质相互作用信息,构建川乌的蛋白互作网络。在此基础上,利用分子复合物检测算法(MCODE),对网络进行模块分析及功能注释,结果显示川乌抗炎作用机制主要与前列腺素代谢过程,趋化因子介导的白细胞趋化作用有关。该研究从分子网络水平系统探讨了川乌的抗炎机制,为川乌治疗风湿性疾病的研究提供科学依据。

Anti-inflammatory mechanism analysis of antirheumatic Chinese medicinal herb Aconiti Radix based on protein interaction network

Inflammation is one of the important risk factors of rheumatic diseases. Aconiti Radix is widely used for the treatment of rheumatism, which has significant anti-inflammatory effects. However, its anti-inflammatory mechanism on molecular level is still not clear. The purpose of this study is to illuminate the anti-inflammatory mechanism of Aconiti Radix based on the protein interaction network (PIN) analysis on molecular network level. The main anti-inflammatory components (aconitine, hypaconitine and mesaconitine) were chosen in this study to obtain the targets of the components and protein-protein information though databases retrieval and construct the PIN of Aconiti Radix. By a graph theoretic clustering algorithm molecular complex detection(MCODE), 13 modules were identified and analyzed by gene ontology(GO) enrichment. The results showed that the anti-inflammatory mechanism of Aconiti Radix was mainly associated with prostanoid metabolic process and leukocyte chemotaxis mediated by chemokines. In this study, the anti-inflammatory mechanism of Aconiti Radix was elucidated systematically from molecular network level, which provided the scientific basis for the treatment of rheumatic diseases.
