Abstract

Oligonucleotides can be used to inhibit the binding of basic fibroblast growth factor to cells. Though standard phosphodiester oligonucleotides show a slight inhibition of binding, the oligonucleotides with phosphorothioate internucleoside linkages have inhibition levels equivalent to that of the polyanion heparin. Variations in sequence of the oligonucleotides does lead to differences in the inhibitory action of the oligonucleotides. This inhibition of basic fibroblast growth factor by phosphorothioate oligonucleotides may account for much of the published data on inhibition of various genes by proposed antisense oligonucleotides and needs to be taken into account when considering the mechanism of action of oligonucleotides in biological systems.
