Transcriptional activation induced by the hTERT promoter.

<p>The pGL3-hTERT-Luc, pGL3-Basic or pGL3-Control plasmids were co-transfected with pRL-SV40 plasmid into each cell line. The relative luciferase activity was determined. All data of firefly luciferase activity were corrected for renilla luciferase activity to account for variation in transfection efficiency and expressed as a percentage of results using the positive control. Each transfection was conducted in triplicate, and data represent the mean±sd.
