Antimessenger oligodeoxyribonucleotides: an alternative to antisense RNA for artificial regulation of gene expression--a review.
Synthetic oligodeoxyribonucleotides (oligos) are now widely used as artificial regulators for gene expression both in cell-free media and in cultured cells. We describe the biological consequence of the various chemical modifications that have been introduced into the molecules to improve their resistance against nuclease attack, their affinity for the target mRNA and their uptake by cells. We also describe the rising generation of antimessenger oligos. Covalently linked to reactive groups these molecules direct irreversible modifications of the complementary nucleic acids. We anticipate that these oligos will be targeted to double-stranded nucleic acids to interfere with gene expression at the DNA level.
