ABSTRACT:
Oligonucleotides are provided which are targeted to nucleic acids encoding human raf and capable of inhibiting raf expression. In preferred embodiments, the oligonucleotides are targeted to mRNA encoding human c-raf or human A-raf. The oligonucleotides may have chemical modifications at one or more positions and may be chimeric oligonucleotides. Methods of inhibiting the expression of human raf using oligonucleotides of the invention are also provided. The present invention further comprises methods of inhibiting hyperproliferation of cells and methods of treating abnormal proliferative conditions which employ oligonucleotides of the invention.
