NF-κB signaling was involved in Aurora-A-promoting radioresistance in HCC cells. a MTT assays were employed to evaluate survival fractions of the stably transfected HCC cells plus LPS and IR (4.0Gy). b A representative image of colony formation in the stably transfected HCC cells plus LPS and IR (4.0Gy) after 14 days. c Flow cytometric detection of apoptosis in the stably transfected HCC cells plus LPS and IR (4.0Gy). d Western blot detection of the expression of those proteins (p65, Bcl-2, Mcl-1, cleaved PARP and caspase-3) in the stably transfected HCC cells plus LPS. GAPDH was used as an internal control. Data represent the mean ± S.E. of three individual experiments with triplicates. *p < 0.05 and**p < 0.01
