Triplex-directed modification of genes and gene activity.

Oligonucleotides offer enormous potential for manipulating gene function in cells and, as such, constitute a promising new class of pharmaceutical agents. Oligonucleotides that form triple helices (triplexes) at specific DNA sequences in defined genes can be used to reduce transcription selectively, to introduce site-specific mutations or to stimulate gene-specific targeted recombination.
