T-antigen expression in proliferating and non-proliferating simian virus 40-transformed mouse cells.

abstract：:The oncolytic herpes simplex virus (HSV) that has been approved for clinical practice and those HSVs in clinical trials are attenuated viruses, often with the neurovirulence gene γ134.5 and additional genes deleted. One strategy to engineer nonattenuated oncolytic HSVs consists of retargeting the viral tropism to a ca...
