The rodent established cell lines LTk- and NIH 3T3 have been used as recipients in gene transfer experiments to study the effect of interferon treatment on the genetic and oncogenic transformation by several genes of viral and cellular origin. Our results show that interferon severely inhibits, to a similar extent, the stable transformation of Ltk- and NIH 3T3 cells by the chicken thymidine kinase (tk) gene, Ecogpt gene, simian virus 40, v-Ha-ras, and human c-Ha-ras and c-Ki-ras oncogenes. These results are consistent with an inhibition by interferon at the level of stabilization or integration, or both, of exogenous DNA sequences in the recipient cells, with an apparent effect on gene expression.
啮齿动物建立的细胞系LTk-和NIH 3T3已被用作基因转移实验的受体,以研究干扰素处理对几种病毒和细胞来源基因的遗传和致癌转化的影响。我们的结果表明,干扰素在相似程度上严重抑制鸡胸苷激酶(tk)基因、Ecogpt基因、猿猴病毒40、v-Ha-ras、人c-Ha-ras和c-Ki-ras癌基因对Ltk-和NIH 3T3细胞的稳定转化。这些结果与干扰素在受体细胞中外源DNA序列的稳定或整合水平或两者水平上的抑制作用一致,对基因表达有明显影响。
