Mucosal high risk human papillomaviruses (HPVs) have been shown to be the major cause of cervical cancer. However, the reason why the low risk HPVs only cause proliferative but non-invasive lesions of infected epithelia remains elusive. Because p53 interacts with high risk HPVs E6 and plays a very important role in carcinogenesis, it is assumed that low risk HPVs E6 might interact with p53 in a different pattern. We used mammalian green fluorescent protein (GFP) tagged and polyhistidine (His) tagged proteins expression systems to express HPV-11E6 fusion proteins in wild-type (wt)p53 cell lines, such as 293T and MCF-7 cells to trace the traffic and location of E6s and p53. We showed that: (1) Following transfection, HPV-11E6 was predominantly expressed in the cytoplasm; (2)Using immunocytochemistry and Western blotting, endogenous wt p53 was shown to be trapped in cytoplasm by HPV-11E6 expression. (3) Apoptosis was increased in HPV-11E6 expressed cells. In conclusion, the entrapment of endogenous wt p53 in cytoplasm by the low risk HPV-11E6 may be one of the reasons why low risk HPV is not able to induce malignant transformation.
