<p>The K-RAS oncogene is a member of the highly conserved RAS gene family, whose protein products are believed to play a significant role in signal transduction and the regulation of cellular proliferation. Mutation-activated K-RAS is found in 30-50% of both advanced and early stage ovarian cancers. The present invention relates to a method for modulating mutation-activated K-RAS esxpression in ovarian, colon, lung, thyroid, prostate, skin, and hematologic cancer cells by administering an effective amount of an oligonucleotide targeted ageinst a portion of mRNA for human K-RAS. Oligonucleotides are provided that are specifically hybridizable with mRNA encoding mutation-activated human K-RAS. Such oligonucleotides can be used for therapeutics and diagnostics as well as for research purposes. The present invention further encompasses pharmaceutical compositions comprising the antisense oligonucleotides of the invention.</p> |
