Dose-response curve to drug treatment. Cytotoxicity of paclitaxel, docetaxel and doxorubicin at various concentrations for MCF-7CC, MCF-7TXT and MCF-7DOX cells was determined following 24 h drug treatment as described in Methods. The means of at least three independent experiments are plotted. The error bar is the standard error; most of them are smaller than the symbols of the plot.
