Abstract

Objective: To study the mechanism of genistein derivatives apoptosis in U87-MG cells. Methods: The experiments were divided into a control group and genistein derivative groups(10,20,40 μmol·L-1). In vitro anti-proliferative activity of cells was evaluated by MTT. Apoptosis of cells was characterized by flow cytometry. Quantitative fluorescent PCR instrument was used to detect the levels of Bax mRNA,Bcl-2 mRNA,Cyt c and Caspase-3 mRNA in the cells. Laser confocal was applied to detect the mitochondrial membrane potential changes. Reactive oxygen content,microplate reader are used to detect the activity of Caspase-3 enzyme. Results: As the concentration of genistein derivatives increases,the inhibitory effect on U87-MG cells increases. And the amount of cell apoptosis is concentration-dependent,with an IC50 of 20.23 μmol·L-1. Quantitative fluorescence PCR results -1 showed that the gene expression level of Bax mRNA,Bcl-2 mRNA and Caspase-3 mRNA increased significantly (P<0.05). When the concentration is 20 μmol·L-1,the mitochondrial membrane potential decreases significantly. The generation of reactive oxygen species was also dependent on the concentration of the drug with the apoptosis of cells. The activity of the Caspase-3 enzyme reached the extreme Significant level(P<0.01)when the drug concentration was 40 μmol·L-1. Conclusion: The genistein derivative(Ged)can inhibit the proliferation of U87- MG cells,enhance the generation of reactive oxygen clusters,and reduce the mitochondrial membrane potential. With the increase of the amount of apoptosis,the activity of Caspase-3 enzyme increases. The genistein derivatives have strong anticancer activities.
