Formation of hybrids between viral deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) was used to detect virus-specific RNA in the nuclei and polyribosomes of transformed and tumor cells induced by "highly" oncogenic human adenovirus (Ad) types 12, 18, and 31. The presence of virus-specific RNA in the cell nucleus, and the inhibitory effect of actinomycin D on its synthesis, suggest that adenovirus-specific RNA is transcribed from a DNA template in the nucleus. Ad 12, 18, and 31 virus-specific RNA did not hybridize significantly with the DNA of the "weakly" oncogenic adenovirus group (Ad 3, 7, 11, 14, 16, and 21) or with that of nononcogenic Ad 2 and 4. Labeled RNA from Ad 12, 18, and 31 tumor cells hybridized with heterologous Ad 12, 18, and 31 DNA 30 to 60% as efficiently as with homologous DNA. Thus, common viral genes are transcribed in tumor cells induced by Ad 12, 18, and 31.
利用病毒脱氧核糖核酸(DNA)与核糖核酸(RNA)形成杂交体的方法,来检测由“高”致癌性人腺病毒12型、18型和31型诱导的转化细胞和肿瘤细胞核及多核糖体中的病毒特异性RNA。细胞核中存在病毒特异性RNA,以及放线菌素D对其合成的抑制作用,表明腺病毒特异性RNA是从细胞核中的DNA模板转录而来。腺病毒12型、18型和31型的病毒特异性RNA与“低”致癌性腺病毒组(腺病毒3型、7型、11型、14型、16型和21型)的DNA或非致癌性腺病毒2型和4型的DNA均未发生明显杂交。来自腺病毒12型、18型和31型肿瘤细胞的标记RNA与异源腺病毒12型、18型和31型DNA杂交的效率,为与同源DNA杂交效率的30%至60%。因此,腺病毒12型、18型和31型诱导的肿瘤细胞中会转录共同的病毒基因。
