Estimating the term…
It is possible to radiosensitize tumor cells by administration of compositions containing the Human antisense c-raf-1 oligodeoxyribonucleotide (ODN/oligo) sequence: 5′-GTGCTCCATTGATGC-3′ (seq. #1) wherein only the end bases are phosphorylated is a preferred embodiment. Antisense sequences of up to 40 bases which containing this sequence may be used in accord with the teachings of this disclosure. Compositions comprising a cationic liposome of dimethyldioctadecyl ammonium bromide, phosphatidylcholine and cholesterol may be used as a carrier system. The liposomes provide a new carrier system that is particularly useful for administration of sequences for therapy.
A composition comprising a cationic liposome containing a cationic lipid, phosphatidylcholine and cholestrol.
A method of radiosensitizing tumor tissue by administration of a radiosensitizing effective amount of at least one antisense oligonucleotide of no more than 40 bases containing the sequence 5′-GTGCTCCATTGATGC-3′.
A composition of matter comprising liposomes containing the sequence 5′-GTGCTCCATTGATGC-3′ in a pharmaceutically acceptable carrier.
