摘要: Background The neurotropic herpes simplex virus mutant HSV1716 lacks the gene encoding virulence factor ICP34.5 and cannot replicate in nondividing cells where proliferating cell nuclear antigen (PCNA) is not actively engaged cellular DNA synthesis. In brain, tumoral expression of PCNA therefore confers on it oncolytic specificity may determine its efficacy. Three phase I trials glioma patients one metastatic melanoma have established that safe replicates selectively tumour tissue. Here we examine situ profiles common human brain tumours their vitro permissivity for replication to ascertain suitability therapy.
