DNA sequences from BK virus have been detected by measurements of reassociation kinetics in DNA preparations isolated from five of 12 human tumor tissues and three of four human tumor cell lines; no DNA sequences from BK virus could be found using the same assay in DNA samples obtained from nontumor tissues removed from various patients. Whether or not this association is trivial, indicative of infection by BK virus, or correlative with the tumor state must await the testing of additional samples of normal and tumor tissues as well as a definition of the physical state of the genome of BK virus.
通过对从12个人类肿瘤组织中的5个以及4个人类肿瘤细胞系中的3个分离得到的DNA制剂进行重缔合动力学测量,已检测到BK病毒的DNA序列;而在从不同患者切除的非肿瘤组织获得的DNA样本中,使用相同检测方法未发现BK病毒的DNA序列。这种关联是微不足道、表明BK病毒感染还是与肿瘤状态相关,必须等待对更多正常和肿瘤组织样本进行检测以及对BK病毒基因组物理状态进行定义。
