人乳头瘤病毒(HPV)E7癌蛋白与腺病毒E1a、SV40大肿瘤抗原等蛋白在功能上具有相似性。作为HPV相关肿瘤中仅有的两种病毒蛋白之一,E7在病毒生命周期和致癌转化过程中发挥着核心作用。在HPV病毒的生命周期中,E7破坏了正常上皮细胞分化和增殖之间的密切联系,允许病毒在不再处于分裂群体中的细胞中复制。这一功能直接反映在E7的转化活性中,包括启动肿瘤和诱导基因组不稳定性。
The human papillomavirus (HPV) E7 oncoprotein shares functional similarities with such proteins as adenovirus E1A and SV40 large tumor antigen. As one of only two viral proteins always expressed in HPV-associated cancers, E7 plays a central role in both the viral life cycle and carcinogenic transformation. In the HPV viral life cycle, E7 disrupts the intimate association between cellular differentiation and proliferation in normal epithelium, allowing for viral replication in cells that would no longer be in the dividing population. This function is directly reflected in the transforming activities of E7, including tumor initiation and induction of genomic instability.
