Fig. 2: Overexpression of LUC7L2 promoted radioresistance of NPC cells.

A Comparison of LUC7L2 expression levels in CNE2 and CNE2IR cells. β-actin served as a loading control. B Western blot validation on the establishment of CNE2 cell line with stable LUC7L2 overexpression. β-actin served as a loading control. C Overexpression of LUC7L2 promoted CNE2 radioresistance. LUC7L2 (6 Gy) vs. NEG (6 Gy), n = 5, P < 0.001. D Clonogenic survival analysis on the radioresistance of CNE2 NEG and CNE2 LUC7L2. The colony formation in CNE2 NEG or CNE2 LUC7L2 without IR was regarded as 100%, respectively. LUC7L2 (6 Gy) vs. NEG (6 Gy), n = 3, P < 0.05.
