Abstract:Triplex forming oligos (TFOs) that target psoralen photoadducts to specific DNA sequences have generated interest as a potential agent in gene therapy. TFOs also offer an opportunity to study the mechanism of DNA repair in detail. In an effort to understand the mechanism of DNA repair at a specific DNA sequence in real-time, we have designed a plasmid containing a psoralen reaction site adjacent to a TFO binding site corresponding to a sequence within the human interstitial collagenase gene. Two 2-aminopurine … Show more
