 AB    Molecular biologists are beginning to apply the site-specific RNase
       properties of ribozymes to gene therapy for HIV infection and cancer.
       Requirements for substrate recognition and cleavage are being finely
       mapped. Methods of augmenting intracellular cleavage and of dissecting
       observed discrepancies between in vitro and cellular activity are being
       explored. Antiviral efficacy against HIV type 1 has been seen in tissue
       culture for both hammerhead and hairpin ribozymes, and a phase I
       clinical trial for ex vivo T-cell gene therapy is planned. Oncogene
       transcripts, such as the bcr/abl fusion messenger RNA and ras, have also
       been targeted with ribozymes.
