Abstract:
Background: Huangqi-Shanzhuyu (HS), a classic combination of Chinese herbal
formulae, has been widely used for the treatment of diabetic nephropathy (DN). However, its
pharmacological mechanism of action is still unclear.
Methods: The active ingredients of HS and their potential targets were identified through the
Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP)
and the DN-related targets were determined from GeneCards, Online Mendelian Inheritance in
Man (OMIM), PharmGkb, and Therapeutic Target Database (TTD). The Cytoscape software
was used to construct a herb-disease-target network and screen core genes. STRING was employed
to generate a protein-protein interaction (PPI) network. Gene Ontology and Kyoto Encyclopedia
of Genes and Genomes (KEGG) enrichment analyses were performed to predict the
mechanism of action of HS in DN. Animal experiments and molecular docking were used to verify
the potential mechanism.
Results: In total, 40 active ingredients and 180 effective targets of HS in DN were identified and
1115 DN-related targets were retrieved. From the PPI network, VEGFA, AKT1, IL6, IL1B,
TP53, MMP9, PTGS2, CASP3, EGF and EGFR were identified as core genes. The anti-DN
mechanism mainly involved multiple signaling pathways such as AGEs-RAGE. Animal experiments
and molecular docking analysis confirmed that HS downregulated the expression of IL-1
and IL-6 via kaempferol-mediated inhibition of JNK1 phosphorylation.
Conclusion: HS exhibits a therapeutic effect in DN through its multiple ingredients that act on
several targets and multiple signaling pathways, including AGEs-RAGE.
