Abstract:
Background: Diabetic neuropathic pain seriously affects the quality of a patient’s life. To predict
molecular mechanism based on network pharmacology and verify the interaction between the active
ingredient of Astragalus membranaceus and Panax notoginseng coupled-herbs (AP) and target genes
related to Diabetic neuropathic pain (DNP) molecular docking assay was performed. AP and their target
genes related to DNP were analyzed based on network pharmacology followed by experimental validation.
Methods: TCMSP, PubMed and CNKI websites were used to acquire active components in AP. OMIM,
DrugBank database and DisGeNET database were used to collect and analyze target genes related to
DNP. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and gene ontology (GO) analysis
were conducted in the DAVID database. The protein-protein interaction (PPI) network model was constructed
by introducing the selected components-disease common target into the string database. Auto-
Dock Vina 1.1.2 was used to dock receptor proteins with small ligand molecules. VonFrey’s statement
was used to detect mechanical allodynia of DNP rats. Potential targets were detected by Western blot
assay.
Results: We decided that 22 and 9 chemical compositions possessed the fair ability of absorption, distribution,
metabolism and excretion in Astragalus membranaceus and Panax notoginseng, respectively.
These active compositions act on 70 target genes related to DNP. The core gene in the protein-protein
interaction network are CAT, ESR1, HMOX1, IL1β, IL6, NFE2L2, NOS2, PPARG, PTGS2 and TNF,
etc. Furthermore, GO, and KEGG pathway enrichment analyses indicated that DNP related target genes
regulated by AP exist in multiple signaling pathways, including insulin resistance, PI3K-Akt signaling,
HIF-1 signaling pathway, Fluid shear stress and atherosclerosis, and AGE-RAGE signaling pathway etc.
AP inhibited mechanical hyperalgesia and reduced SERPINE1, FN1, IL1β, and IL6 expression of diabetic
neuropathic rats in a dose-dependent manner.
Conclusion: We first confirm that AP possess an anti-DNP effect through multiple signaling pathways
based on network pharmacology. These results provide a theoretical basis for us to further research on the
molecular mechanism of AP in the treatment of DNP.
