Fig. 5From: Targeting Rad50 sensitizes human nasopharyngeal carcinoma cells to radiotherapyAd-RAD50 enhanced the IR-induced cell growth suppression and IR sensitivity. a Cell growth suppression was measured by the MTT assay. NPC cells treated with Ad-RAD50 and 4Gy IR combination exhibited significant persistent proliferative suppression compared to all the other treatments. b and c Colony formation assay showed that Ad-RAD50 infection inhibited the cells survival fractions (* P < 0.05, ** P < 0.01)Back to article page
