Potential Molecular Mechanisms of Chaihu-Shugan-San in Treatment of Breast Cancer Based on Network Pharmacology

Abstract EN

Breast cancer is one of the most common cancers endangering women’s health all over the world.

Traditional Chinese medicine is increasingly recognized as a possible complementary and alternative therapy for breast cancer.

Chaihu-Shugan-San is a traditional Chinese medicine prescription, which is extensively used in clinical practice.

Its therapeutic effect on breast cancer has attracted extensive attention, but its mechanism of action is still unclear.

In this study, we explored the molecular mechanism of Chaihu-Shugan-San in the treatment of breast cancer by network pharmacology.

The results showed that 157 active ingredients and 8074 potential drug targets were obtained in the TCMSP database according to the screening conditions.

2384 disease targets were collected in the TTD, OMIM, DrugBank, GeneCards disease database.

We applied the Bisogenet plug-in in Cytoscape 3.7.1 to obtain 451 core targets.

The biological process of gene ontology (GO) involves the mRNA catabolic process, RNA catabolic process, telomere organization, nucleobase-containing compound catabolic process, heterocycle catabolic process, and so on.

In cellular component, cytosolic part, focal adhesion, cell-substrate adherens junction, and cell-substrate junction are highly correlated with breast cancer.

In the molecular function category, most proteins were addressed to ubiquitin-like protein ligase binding, protein domain specific binding, and Nop56p-associated pre-rRNA complex.

Besides, the results of the KEGG pathway analysis showed that the pathways mainly involved in apoptosis, cell cycle, transcriptional dysregulation, endocrine resistance, and viral infection.

In conclusion, the treatment of breast cancer by Chaihu-Shugan-San is the result of multicomponent, multitarget, and multipathway interaction.

This study provides a certain theoretical basis for the treatment of breast cancer by Chaihu-Shugan-San and has certain reference value for the development and application of new drugs.
