DNA damage-responsive transgene expression mediated by the p53 promoter with transcriptional amplification

J Biosci Bioeng. 2015 Oct;120(4):463-6. doi: 10.1016/j.jbiosc.2015.02.009. Epub 2015 Mar 12.

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.
