Regulation of miR-133b/EGFR axis in related signaling pathways of ESCC cells. a, c The protein levels of ITGB4, p-FAK, FAK, Grb2, p-AKTThr308, p-AKTSer473, p-ERK1/2, and ERK1/2 in KYSE150 and ECa109 cells were assessed by western blotting. b, d 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
