A procedure is described permitting the detection of viral-specific RNA in a mouse mammary tumor. The method involves molecular hybridization with radioactively labeled DNA complementary to the RNA of the mouse mammary-tumor virus. RNA homologous to that of the mammary agent has been found in both the nuclear and polyribosomal fractions of tumor cells. The results imply that the oncogenic information is serving as messenger RNA that directs the synthesis of proteins required for virus production, and perhaps for the maintenance of the neoplastic state. The technology developed is immediately applicable to tumors of human origin.
本文描述了一种用于检测小鼠乳腺肿瘤中病毒特异性RNA的方法。该方法涉及用与小鼠乳腺肿瘤病毒RNA互补的放射性标记DNA进行分子杂交。在肿瘤细胞的核和多核糖体部分均发现了与乳腺病原体RNA同源的RNA。结果表明,致癌信息作为信使RNA指导病毒产生所需蛋白质的合成,或许也指导维持肿瘤状态所需蛋白质的合成。所开发的技术可立即应用于人类起源的肿瘤。
