Antisense–ribozyme technology has evolved from being a tool in molecular biology to being used as a therapeutic agent in human disease. There is enormous potential in antisense and ribozyme therapy, but significant pitfalls and obstacles have yet to be overcome.

Keywords: phosphorothioate oligodeoxynucleotides; cationic liposomes; retroviral vector; adenoviral vector; multidrug resistance; biological therapy

Figure 1. Conserved sequences of the hammerhead ribozyme and position relative to its target ribonucleic acid (RNA). The conventional numbering system for the specific bases has been included. Required bases have been identified; other variable bases have been designated as ‘N’. Cleavage occurs 3¢ to the N at position 17.
Figure 2. Consensus sequences of the hairpin ribozyme and position relative to its substrate.
