Recently, a Schwartz attenuated strain of MV containing a transgene encoding the suicide gene super cytosine deaminase (MV-SCD) has been studied to kill sarcoma tumor cell lines that are sensitive to MV infection, but where the MV fail to replicate due to innate antiviral mechanism, such as IFN-stimulated genes [64]. The gene discussed is IFNA1; the disease is neoplasm.
