Cytotoxicity of GA in MCF-7 cells with low vimentin expression. A, Western blotting assay of levels of vimentin in HeLa cells and MCF-7 cells with or without GA treatment (2 μm GA for 3 h or 24 h). B, Western blotting assay with increased exposure time to detect vimentin in MCF-7 cells with or without GA treatment (2 μm GA for 3 h). C, Effects of GA on viability of HeLa cells or MCF-7 cells. Cells were treated with different doses of GA for 72 h and cell viability was determined by MTT assay. Data were statistical results of three independent experiments (n = 3, mean ± S.E.).
