Immunization of crossbred and F1 mice with combined killed and live Gross leukemia virus AKR type-C viral vaccines suppressed endogeneous N-type AKR virus up to 10,000-fold for significant periods during early life. Since several previous studies in the same and similar crossbred systems revealed direct correlations between low and high levels of type-C virus early in life with low and high incidences of leukemia and other cancers later in life, we believe that prospects for suppression of spontaneous neoplasms are good; however, 8-14 months will be required to achieve the final results. Should cancers be prevented by serotype-specific vaccines, such evidence would provide conclusive proof of endogenous viral etiology.
用灭活和活的格罗斯白血病病毒AKR-C型病毒联合疫苗对杂交和F1代小鼠进行免疫接种,在其生命早期的相当长一段时间内,可将内源性N型AKR病毒抑制达10000倍。由于此前在相同及类似杂交系统中的多项研究表明,生命早期C型病毒水平的高低与后期白血病及其他癌症的发病率高低直接相关,我们认为抑制自发肿瘤的前景良好;然而,要取得最终结果还需要8至14个月。如果血清型特异性疫苗能够预防癌症,此类证据将为内源性病毒病因提供确凿证明。
