Fig. 6: DDR1-IN-1 induced synergistic cell death with other anti-MPNST agents.

S462 MPNST cells were treated with 5 μM DDR1-IN-1 combined with 0-100 μM doxorubicin (A), etoposide (B), PD0325901 (C), or SHP099 (D) for 48 hours. Cell viability was evaluated through the MTT assay and the IC50 was calculated. The cell viability of cells exposed to 5 μM DDR1-IN-1 and/ or 10 μM anti-MPNST agents were plotted as bar charts as indicated, and the p-value was demonstrated (n = 3). *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
