Background:According to traditional Chinese medicine (TCM),drugs supplementing the vital energy,Qi,can eliminate tumors by restoring host immunity.The objective of this study is to investigate the underlying immune mechanisms of anti-tumor activity associated with Qi-supplementing herbs,specifically the paired use of Huangqi and Danggui.Methods:Analysis of compatibility regularity was conducted to screen the combina-tion of Qi-supplementing TCMs.Using the MTT assay and a transplanted tumor mice model,the anti-tumor effects of combination TCMs were investigated in vitro and in vivo.High content analysis and flow cytometry were then used to evaluate cel-lular immunity,followed by network pharmacology and molecular docking to dissect the significant active compounds and potential mechanisms.Finally,the anti-tumor activity and the mechanism of the active ingredients were verified by molecular experiments.Results:There is an optimal combination of Huangqi and Danggui that,administered as an aqueous extract,can activate immunity to suppress tumor and is more effec-tive than each drug on its own in vitro and in vivo.Based on network pharmacology analysis,PIK3R1 is the core target for the anti-tumor immunity activity of combined Huangqi and Danggui.Molecular docking analysis shows 6 components of the com-bined Danggui and Huangqi extract (quercetin,jaranol,isorhamnetin,kaempferol,calycosin,and suchilactone) that bind to PIK3R1.Jaranol is the most important com-ponent against breast cancer.The suchilactone/jaranol combination and,especially,the suchilactone/kaempferol combination are key for immunity enhancement and the anti-tumor effects of the extract.Conclusions:The combination of Huangqi and Danggui can activate immunity to sup-press breast cancer and is more effective than the individual drugs alone.
