Regulating Viral Replication using RNA Aptazymes
The biggest problem in cancer therapeutics is selectivity. Using oncolytic viral therapies, high selectivity can be achieved using the combination of selective infection and selective replication. Here, we want to address selective replication. For DNA viruses, this can be accomplished with promoters to control transcription and genome replication. However, for RNA viruses, this does not work. A potential solution to control replication for RNA viruses is the use of aptazymes. Aptazymes are self-cleaving units composed of a riboswitch and an aptamer….
