ABSTRACT
BACKGROUND AND PURPOSE:
FuZheng YiLiu Formula (FZYL) is a commonly used formula for postoperative estrogen receptor-positive (ER+) breast cancer and post-radiotherapy deficiency of both Qi and Yin. FZYL has been used in clinical practice for decades because of its ability to effectively improve the symptoms of deficiency in cancer patients. However, its mechanism needs to be further clarified. In this paper, we will observe the effect of FZYL on mice with ER+ breast cancer and explore the mechanism by which it improves the symptoms of ER+ breast cancer. MATERIALS ANDMETHODS:
A tumor xenograft mouse model was established to detect tumor growth in vivo in order to evaluate the pharmacological effects of FZYL on ER+ breast cancer. The main targets of FZYL were identified by extracting the FZYL components and the corresponding potential target genes of breast cancer from the established database and constructing a protein-protein interaction network of shared genes using the string database. GO functional annotation and KEGG pathway enrichment analysis were performed, and molecular docking, molecular dynamics simulations, western blotting analysis, and RT-qPCR were performed to confirm the validity of targets in the relevant pathways.RESULTS:
FZYL was able to significantly reduce the size of tumors in vivo and had a significant therapeutic effect on tumor xenograft mice. GO and KEGG pathway enrichment analyses indicated that the effects of FZYL may be mediated by oxidative stress levels, apoptotic signaling pathways, and cell cycle proliferation. By RT-qPCR and protein blotting assays, FZYL targeted the key targets of TP53, JUN, ESR1, RELA, MYC, and MAPK1 to exert its effects. The key active components of FZYL are quercetin, luteolin, stigmasterol, and glycitein. Molecular docking and molecular dynamics simulation results further demonstrated that the key active components of FZYL are stably bound to the core targets.CONCLUSION:
In this study, the potential active ingredients, potential core targets, key biological pathways, and signaling pathways involved in the treatment of breast cancer with FZYL were identified, providing a theoretical basis for further anti ER+ breast cancer research.
