Examples can be sought in studies involving measles virus expressing NIS (sodium iodide symporter) which in combination with radioisotope of iodine (131I), sequesters it in the tumor and leads to lysis of radiosensitive cancer cells as seen in case of preclinical models of multiple myeloma (27), prostate cancer, glioblastoma multiforme, and medulloblastoma (28). The gene discussed is SLC5A5; the disease is prostate carcinoma.
