Figure 6From: Targeting the epidermal growth factor receptor in non-small cell lung cancer cells: the effect of combining RNA interference with tyrosine kinase inhibitors or cetuximab Effect of adding an EGFR siRNA to erlotinib on cell growth inhibition. Lung cancer cells were treated with erlotinib 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.Back to article page
