Silencing UBQLN2 Enhances the Radiosensitivity of Esophageal Squamous Cell Carcinoma (ESCC) via Activating p38 MAPK

Figure 2

The expression level of UBQLN2 protein in esophageal squamous cell carcinoma (ESCC) cells. (a) The protein expression level of UBQLN2 in four ESCC cell lines and the normal esophageal epithelial cell line Het-1A was detected by Western blotting. (b) The expression of UBQLN2 protein in UBQLN2-siRNAs transfected Ec109 cells was detected by Western blotting. The transfection effect of UBQLN2-siRNA was confirmed by Western blotting at protein levels in Ec109 (c) and KYSE-30 (d) cells. All results are presented as the mean ± SEM from three repeated experiments.  < 0.05,  < 0.01,  < 0.001, and  < 0.0001 of the Student's t-test or analysis of variance (ANOVA).
