  • Structurally modified molecular decoys for the manipulation of cellular or viral replication and other uses relating thereto
    Publication number: 20030040613
    Abstract: Structurally modified, closed-ended nucleic acid decoys for the manipulation of cellular or viral replication processes are described. These decoys are resistant to cellular degradation, do not directly interact with host DNA and their structure does not require sophisticated knowledge of target DNA sequence. They have been demonstrated to be effective as transcription factor sequestration agents. By effectively competing for cellular transcription factors, these decoys will interfere with the normal transcription process, effectively turning off protein production and cellular replication. These decoys also have potential similar actions and effects in viruses. These decoys should have an impact in the treatment of cancer, AIDS, and other diseases.
