Marked differences were found in the susceptibility of human fibroblasts to transformation by simian virus 40 (SV40). Highly susceptible cell strains were derived from patients with diseases associated with chromosomal abnormalities and a high incidence of tumors. In the present study, SV40 transformation-susceptible cell strains were not found to have a generalized increase in viral sensitivity. The differences in transformation frequency among cell strains with whole virus are eliminated by the use of isolated SV40 deoxyribonucleic acid, suggesting that the relative resistance of most cell strains to transformation by whole virus is due to a block at an early step in infection.
在人成纤维细胞对猿猴病毒40(SV40)转化的易感性方面发现了显著差异。高度易感细胞株源自患有与染色体异常和高肿瘤发病率相关疾病的患者。在本研究中,未发现对SV40转化易感的细胞株普遍提高了病毒敏感性。使用分离的SV40脱氧核糖核酸可消除全病毒处理的细胞株间转化频率的差异,这表明大多数细胞株对全病毒转化的相对抗性是由于感染早期的一个阻断步骤所致。
