Fig. 1From: Aurora-a confers radioresistance in human hepatocellular carcinoma by activating NF-κB signaling pathwayEstablishment of radioresistant HCC cells. a A representative image of colony formation in parental and their radioresistant HCC cells treated with various dose of IR (0.0, 4.0 and 6.0 Gy) after 14 days. b The results of colony formation. c Survival fractions of parental and their radioresistant HCC cells were obtained from the results of the colony-forming assays. d Flow cytometric detection of apoptosis in parental and their radioresistant HCC cells treated with various dose of IR (0.0, 4.0 and 6.0 Gy). Data represent the mean ± S.E. of three individual experiments with triplicates. *p < 0.05 and**p < 0.01Back to article page
