Figure 1From: Silencing of insulin-like growth factor-1 receptor enhances the radiation sensitivity of human esophageal squamous cell carcinoma in vitro and in vivoTransfection efficiency of IGF-1r siRNA in vitro . (A) IGF-1r protein expression was analyzed by Western blotting after transfection with IGF-1r siRNA for 72 hours in TE-1 and Eca-109 cells. (B) The transfection efficiency of IGF-1r siRNA was observed by fluorescence microscopy after 72 hours in TE-1 and Eca-109 cells. β-actin was used as a loading control.Back to article page
