Genistein, a soy isoflavone, is a multiple tyrosine kinases (e.g., EGFR) inhibitor which acts as a chemotherapeutic agent against different types of cancer, mainly by altering apoptosis, the cell cycle, and angiogenesis and inhibiting metastasis.

| Invitro | Genistein inhibits serum-stimulated growth of MCF-7 and T47D ER+ cells with IC50 values of 7.6 and 8.7 μg/mL by dye exclusion, respectively, and 8.7 and 10.6 μg/mL by [3H]thymidmne incorporation, respectively. These values are similar to the IC50 values of 9.4 and 7 μg/mL for MCF-7 and T47D ER+ cells, respectively, obtained with the MTT assay. Additionally, Genistein at concentrations up to 20 μg/mL does not alter MTT mitochondrial reduction when compared to control cells in an 8 h incubation period. Furthermore, neither biochanin A or daidzein are found to interfere with the MTT assay at IC50 concentrations. Therefore, the MTT assay is valid for determining growth inhibition by Genistein at concentrations under 20 μg/mL in the systems studied[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||
