MTT assay was conducted to evaluate cell viability after treatment. a IC50 value was determined by various concentrations of Temozolomide. b Cell viability of Temozolomide with or without miR-218 to investigate the synergistic effect. c Cell viability of Temozolomide at different concentrations with miR-218 to investigate the synergistic effect. All data was presented by mean ± SD of experiments done in triplicate wells. Contrasts were considered significant at P < 0.05. Sigmoidal fittings were performed by Graphpad Prism 5.01 software
