Figure 8.

Effect of adding an EGFR siRNA to cetuximab on cell growth inhibition. Lung cancer cells were treated with cetuximab as mentioned in Figure 5. *P < 0.05 and **P < 0.01 compared to controls with only siRNA transfection. "black triangle" P < 0.05 and "double black triangles" P < 0.01 compared to agents plus control siRNA.
