Fig. 6From: Salinomycin decreases feline sarcoma and carcinoma cell viability when combined with doxorubicinDose-dependent effects of doxorubicin and salinomycin in combination in B4 cells. In MTT cell viability assays, dose-dependent effects of doxorubicin were first observed at 46 μM when administered in combination with 2.5 μM of salinomycin. Dose-dependent effects of doxorubicin were first observed at 18.4 μM when administered in combination with 5 μM of salinomycin. Solid dark lines depict the mean generated from statistical modeling for the indicated conditions. Dotted lines represent the upper and lower 95% confidence intervals. P values from individual comparisons are described in the text and are available in Additional file 2Back to article page
