However, the effects of fisetin on breast cancer have rarely been reported and the underlying mechanism is still undefined. The present study explored the anticancer effects of fisetin on mammary carcinoma cells and the underlying mechanisms. Following treatment with fisetin, viability of 4T1, MCF7 and MDAMB231 cells were measured by MTT assay. The inhibitory effects of fisetin on proliferation, migration and invasion were evaluated in 4T1 cells using proliferation array, woundhealing assay, and HUVECCcell barrier based on electrical cellsubstrate impedance sensing platform. Cell apoptosis was analyzed by flow cytometry, and western blotting analysis was performed to identify target molecules. A 4T1 orthotopic mammary tumor model was used to assess the fisetininhibition on tumor growth invivo. Test kits were used to examine the liver and kidney function of tumorbearing mice. The results suggest that fisetin suppressed the proliferation of breast cancer cells, suppressed the metastasis and invasiveness of 4T1 cells, and induced the apoptosis of 4T1 cells invitro. The potent anticancer effect of fisetin was associated with the regulation of the phosphatidylinositol3kinase/protein kinaseB/mammalian target of rapamycin pathway. Invivo experiments demonstrated that fisetin suppressed the growth of 4T1 cellderived orthotopic breast tumors and enhanced tumor cell apoptosis, and the evaluated alanine amino transferase and aspartate amino transferase levels in serum of tumorbearing mice suggested that fisetin may lead to side effects on liver biochemical function. The present study confirms that fisetin exerted an antimammary carcinoma effect. However, invivo experiments also revealed that fisetin had low solubility and low bioavailability. Further investigation is required to determine the clinical value of fisetin.", }
