Effect of S100A7 overexpression on cytotoxicity of breast tumor MDA-MB-468 cell lines. MDA-MB-468 cells were stably transfected with pc.DNA3.1-S100A7 cells. Cell viability was determined by the MTT assay. The growth rate of the pc.DNA3.1-S100A7 transfected MDA-MB-468 cells was significantly increased in the MTT assay. Each bar represents mean ± SE (n = 3); **, P <0.01. MTT, 3-(4,5-dimethythiazol-2-yl)-2,5-diphenyl tetrazolium bromide.
