Abstract

Syrian hamster embryo cells were transformed to a neoplastic phenotype after exposure to herpes simplex virus type 2 (S-1) DNA at concentrations (less than or equal to 0.01 microgram per 60-mm dish) at which infectivity was no longer demonstrable. Transformed cells manifested in vitro phenotypic properties characteristic of the neoplastic state, expressed herpes simplex virus-specific antigens, and induced invasive tumors in vivo. Transfection and transformation of Syrian hamster embryo cells with herpes simplex virus type 2 DNA or its fragments is a suitable system for investigating the structure and function of herpes simplex virus-transforming gene(s).

摘要

叙利亚仓鼠胚胎细胞在暴露于2型单纯疱疹病毒(S-1)DNA后,被转化为肿瘤表型,此时DNA浓度(小于或等于每60毫米培养皿0.01微克)已无法检测到感染性。转化后的细胞表现出肿瘤状态特有的体外表型特征,表达单纯疱疹病毒特异性抗原,并在体内诱发侵袭性肿瘤。用2型单纯疱疹病毒DNA或其片段转染和转化叙利亚仓鼠胚胎细胞,是研究单纯疱疹病毒转化基因结构和功能的合适系统。
