DNA damage produced by 125I-triplex-forming oligonucleotides as a measure of their successful delivery into cell nuclei.


Decay of an Auger-electron-emitting radioisotope can knock out a targeted gene by producing DNA strand breaks within its sequence. For delivery of Auger emitters to genomic targets we used triplex-forming oligonucleotides (TFOs) that bind specifically to their target sequences by forming hydrogen bonds within the major groove of the target duplex. We named… (More)
