Antisense Therapy for Cancer
Antisense therapy is a novel new means of drug action. Antisense is a short section of nucleic acid (an "oligonucleotide")that is complimentary in structure to a cancer gene or its RNA transcript.Antisense combines with the cancer gene and thereby prevents the formation of a protein that is usually involved in runaway cell division.
