EGFR-siRNA treatment reduces EGFR protein expression. (A) EGFR and β-tubulin protein expression in the various groups was detected by western blotting. (B) Semi-quantitative analysis of the EGFR protein expression comparing EGFR to β-tubulin. Data are presented as the mean ± standard deviation of three experiments; *P<0.0001 vs. Control). NC, negative interference siRNA; PC, positive interference siRNA; Control, blank control group (untransfected); EGFR, epidermal growth factor receptor; siRNA, small interfering RNA.
