Fig. 1. (A) Effects of genistein on cisplatin-induced cytotoxicity of CaSki cells. CaSki cells viability examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Representative results are shown as the mean±standard deviation (SD) of triplicates. Values with same superscripts are not significantly different (P<0.05). (B) Effects of genistein on cisplatin-induced cytotoxicity of HeLa cells. Representative results are shown as the mean±SD of triplicates. Values with same superscripts are not significantly different (P<0.05).
