Chart 1. Activation of hTERT promoter-driven SEAP expression by c-Myc. About 1×10⁷ hTERT-BJ1 cells were transfected with 13.5 μg each of plasmid pSEAP or pPhTERT-SEAP and of plasmid pMT2T or pMT2T-cMyc by electroporation. After 24 h, viable cells were harvested, and reinoculated at a density of 3×10⁵/mL, and the SEAP activity after 24 h at 37 □. The transfection efficiency of each experiment was determined by cotransfection with 1.5 μg of plasmid pCMVβ. The values were determined from three experiments. P<0.05 is presented by an asterisk.
