Abstract
We constructed a DNA damage-responsive transgene expression system mediated by the p53 promoter. We incorporated a transactivation system to generate transcriptional amplification via a positive feedback loop. Higher levels of DNA damage-responsive transgene expression were observed when transactivation was active.
Keywords:
DNA damage; Inducible gene expression; Tetracycline transactivator; p53 promoter.
