ANTI-NEOPLASTIC VIRUSES

摘要

A viral DNA construct encoding for a parvovirus that is capable of replication in a human or animal tumour cell is provided. The viral DNA consturct having one or more selected transcription factor binding sites operatively positioned such as to promote expression of open reading frames encoding non-structural viral proteins, wherein the selected transcription factor binding sites are for a transcription factor the level or activity of which is increased in a human or animal tumour cell relative to that of a normal human or animal cell of the same type.
