Abstract:
Objective:To evaluate the therapeutic effects of Epimedium brevicornu Maxim. (EBM, Yin Yang Huo) on breast cancer using network pharmacology and in vitro validation. It also aimed to explore the novel targets and mechanisms of EBM in the treatment of breast cancer to facilitate the discovery of new drugs and their clinical application.
Methods:Network pharmacology was used to identify and screen the components and targets of EBM for breast cancer treatment. Molecular docking was further screened the effective components and targets of EBM. Wound-healing assays and flow cytometry analysis were used to detect the ability of two compounds to intervene in the migration and apoptosis of MDA-MB-231 cells, and their mechanism of action was further explored using western blotting experiments.
Results:EBM contained 19 active components. Among them were β-anhydroicaritin (Anhy) and isoliquiritigenin (Iso), which were selected for in vitro experiments. Treatment resulted in a dose-dependent suppression of MDA-MB-231 cell viability, with an IC50 of 23.73 μmol/L for Iso and 21.28 μmol/L for Anhy. In the wound healing assay, cells in Anhy and Iso groups exhibited considerable inhibition of migration at 48 h. In flow cytometry analysis, treatment with Iso (20 μmol/L) for 96 h resulted in significantly higher levels of both early and late apoptosis in the Iso group than that in the control group (P = .004 and P = .014, respectively). Additionally, both Iso (20 μmol/L) and Anhy (10 and 20 μmol/L) induced cell necrosis at 96 h. Western blotting revealed that Anhy and Iso increased the expression of Bax and TBK1/NAK.
Conclusion:These findings suggested that Anhy and Iso, the two components of EBM, inhibit MDA-MB-231 cell proliferation and migration of and induce their apoptosis, providing substantial support for future studies on breast cancer.
