Bax, Bcl-2, Caspase-3 and Survivin mRNA expression analysis following treatment of EJ cells with TAT-Apoptin (0.1, 0.5, 1, 10, 50 and 100 μg/ml) for 48 h. The differences in expression after treatment with the various concentrations of TAT-Apoptin were calculated using the ANOVA method. The level of mRNA expression of Bcl-2 (F=30.181, P=0.000) and Survivin (F=102.542, P=0.000) in EJ cells was significantly decreased, while that of Bax (F=33.304, P=0.000) and Caspase-3 (F=464.560, P=0.000) increased significantly with increasing concentration of TAT-Apoptin. ANOVA, analysis of variance.
