生物活性	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.

体内研究	In the present study, the effective dose of morphine caused a significant decrease in testis weight of mice compared to Saline group (p=0.00). Moreover, testis weight are significantly increase in treated animals with Genistein and Genistein plus morphine in all doses in comparison with morphine group (p=0.028). Morphine caused a significant decrease in the testosterone, LH and FSH hormones compared to saline group (p=0.00). In addition, the testosterone, LH and FSH hormones increased significantly in Genistein (p<0.05) and Genistein plus morphine in all groups administration compared to morphine group (p=0.024). Bisphenol A (BPA) treatment alone and combined with Genistein had no significant effect on the protein expression of LC3II and PPARα in liver of STD- or HFD-fed rats (P>0.05; P>0.05). Significant decreasing of the protein expression of PPARγ in liver is observed when Genistein is added to rats, compared to either HFD group or HFD-BPA group.
体外研究	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 [H]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.
