Levels of miR-133b, EGFR, ITGB4, and FAK in ESCC tissue samples. a The level of miR-133b, and mRNA levels of EGFR and ITGB4 in 30 pairs of ESCC tissues and corresponding adjacent normal tissues were detected by RT-qPCR. b The protein levels of EGFR, ITGB4, p-FAK, and FAK in ESCC tissues and adjacent normal tissues were evaluated by western blotting assay. c The gray-scale value of the bands were quantitatively analyzed. The experimental data were representative of three independent experiments. Results were expressed as mean ± SD. *P < 0.05, **P < 0.01 and ***P < 0.001
