NCIt definition : The liposomal formulation of a c-raf-1 antisense oligonucleotide, with potential antineoplastic
activity. Liposomal c-raf antisense oligonucleotide targets the translation initiation
site of human c-raf-1 mRNA, thereby blocking the expression and production of Raf-1
protein and thus inhibit tumor cell growth and development. Raf-1 plays a key role
in the RAF/MEK/ERK signaling pathway, which regulates mammalian cell proliferation
and growth. The liposomal formulation increases the solubility of the c-raf antisense
oligonucleotide, thus improving its pharmacodynamic profile.;
