| Outline of Final Research Achievements |
Retroviral replicating vectors (RRV) have demonstrated efficient tumor transduction and dramatic survival benefit when employed for suicide gene in a variety of cancer models. In order to increase transduction efficiency and enhance therapeutic effect, we have created two different RRVs (AMLV and GALV) that use different receptors. Using these vectors, we showed a potential feasibility of a personalized virotherapy on the basis of the cellular receptor expression profiles, and also a dual-vector suicide gene therapy using two different RRVs carrying different suicide genes. Furthermore, we also showed the potential utility of tumor-homing mesenchymal stem cells to deliver RRV more efficiently and further enhance the efficacy of RRV-mediated gene therapy for systemic and metastatic cancers.
