With gentle cell extraction techniques, various DNA components in the HeLa cells after 6 h of adenovirus infection have been obtained. Adenovirus, early transcribed regions (E2a, E1b) and a late transcribed region (L2) were used as probes in Southern hybridization, respectively. The experiment showed that only actively transcribed adenovirus DNA fragments would tightly bind to the nuclear matrix of host cells. We inferred that the nuclear matrix of host cells plays an important role in viral DNA transcription.
采用温和的细胞提取技术,获得了腺病毒感染6小时后HeLa细胞中的各种DNA成分。分别以腺病毒、早期转录区域(E2a、E1b)和晚期转录区域(L2)作为探针进行Southern杂交。实验表明,只有活跃转录的腺病毒DNA片段会紧密结合到宿主细胞的核基质上。我们推断宿主细胞的核基质在病毒DNA转录中起重要作用。
