Anti-cancer Mechanism of "Clematis Radix et Rhizoma-Trichosanthis Radix" Based on Network Pharmacology / 中国实验方剂学杂志

ABSTRACT

Objective:To explore the potential targets and mechanism of action of "Clematis Radix et Rhizoma-Trichosanthis Radix" based on network pharmacology. Method:Chinese Medicine System Pharmacology Analysis Platform（TCMSP） was used to screen out active ingredients and corresponding target proteins of Clematis Radix et Rhizoma and Trichosanthis Radix according to oral bioavailability（OB） and drug likeness（DL），cancer disease targets were screened out using GeneCards and OMIM databases，R language software was used to screen out common targets of clematis，trichosanthin and cancer diseases， Cytoscape 3.7.2 software was used to construct a network map of "drug-active ingredient-disease-target"， STRING database was used to draw protein protein interaction（PPI）of common target proteins， R language software was used to perform enrichment analysis of gene ontology（GO） functions and Kyoto encyclopedia of genes and genomes（KEGG） channels on effective targets. Result:A total of 9 effective active ingredients were obtained from Clematis Radix et Rhizoma-Trichosanthis Radix powder pair. A total of 31 target genes were searched，and 814 relevant target genes were searched from cancer diseases. The two kinds of relevant target genes were matched to obtain 9 common target genes，which mainly involved endopeptidase，cysteine-type endopeptidase activities involving in the apoptosis process and cancer necrosis factor receptor superfamily binding and other biological processes，and played a role in the treatment of cancers by regulating apoptosis，measles，hepatitis B，kaposi sarcoma-associated herpesvirus infection，p53，interleukin-17（IL-17），tumor necrosis factor（TNF） and many other pathways. Conclusion:The mechanism of Clematis Radix et Rhizoma-Trichosanthis Radix in the treatment of cancer is preliminarily studied. Clematis Radix et Rhizoma-Trichosanthis Radix has multiple active ingredients and can play a role in treating cancer through multiple targets and multiple pathways.
