Abstract
OBJECTIVE To investigate the regulation effects of main active components in Honghua Injection on cerebrovascular disease network. METHODS Cerebrovascular disease network was constructed using genes from public database RGD based on the protein-protein interaction (PPI) relationship databases HPRD and BioGRID. Then targets of five main active components in Honghua injection was retrieved from PubMed. Component-target relationships were extracted and associated with PPI in cerebrovascular disease. Component-target network was constructed with Cytoscape 3.1.0 . Network analysis technologies were applied to find critical targets, biological pathways and potential synergistic effects among components. RESULTS The component-target network contains 940 nodes and 2 360 edges. MCODE analysis extracted 28 clusters in which 18 clusters had at least 3 nodes. There were 6 clusters with score ≥3, and they were further investigated using BinGO analysis. The results showed that the main biological processes included regulation of macromolecule biosynthetic and metabolic processes, neurogenesis, apoptosis, angiogenesis, immune-inflammation reaction, response to hypoxia stress. Our study also indicated that Hydroxysafflor yellow A and Quercetin may show their cerebrovascular-protective potential based on their synergistic anti-apoptosis effects. CONCLUSION From the view of molecular network, our study applied network pharmacology METHODS and technologies to reveal the multi-target, multi-pathway mode of action of Honghua injection on anti-cerebrovascular disease effects, and the synergistic effects among Hydroxysafflor yellow A and quercetin.
