Dose dependent changes in the viability of soft tissue sarcoma cells in the presence of salinomycin, doxorubicin, and the combined treatment. The impact of salinomycin was analyzed at different concentrations as indicated (A). Cell viability of adherent growing SW872 (B), A204 (C) and HT-1080 (D) cells was measured by MTT assay 48 h post doxorubicin treatment. Error bars denote the standard error (n = 3). Student’s t-test was conducted to determine the significance (* p < 0.05, ** p < 0.01, *** p < 0.001).
