Complementary DNA (cDNA) specific for chick globin mRNA sequences fails to hybridize to total RNA extracted from chicken fibroblasts. After infection by Rous sarcoma virus, RNA complementary to globin cDNA is detectable in 100-500 copies per cell. Infection of fibroblasts with the transformation defective (td) deletion mutant of Rous sarcoma virus leads to normal virus production, but not to host cell transformation or accumulation of RNA sequences complementary to globin cDNA. Our evidence shows that the globin genes activated by Rous sarcoma virus are those specified by embryonic chick red cells; adult-specific globin sequences were not detected.
对鸡珠蛋白mRNA序列具有特异性的互补DNA(cDNA)无法与从鸡成纤维细胞中提取的总RNA杂交。经劳氏肉瘤病毒感染后,每个细胞中可检测到100 - 500个拷贝的与珠蛋白cDNA互补的RNA。用劳氏肉瘤病毒的转化缺陷(td)缺失突变体感染成纤维细胞,可导致正常的病毒产生,但不会导致宿主细胞转化或与珠蛋白cDNA互补的RNA序列积累。我们的证据表明,劳氏肉瘤病毒激活的珠蛋白基因是胚胎期鸡红细胞所特有的基因;未检测到成年期特异性珠蛋白序列。
