皮肤β人乳头瘤病毒(βHPV)类型似乎与皮肤癌发生有关。然而,迄今为止,仅对少数 β HPV 进行了研究。在这里,我们比较了来自六种未表征的 β HPV(14、22、23、24、36,49)的 E6 和 E7 癌蛋白的特性。只有 HPV49 E6 和 E7 能够使原代人角质形成细胞永生化,并有效地解除 p53 和 pRb 途径的调节。此外,HPV49 E6 与致癌 HPV16 中的 E6 类似,可促进 p53 降解。
The cutaneous beta human papillomavirus (beta HPV) types appear to be involved in skin carcinogenesis. However, only a few beta HPVs have been investigated so far. Here, we compared the properties of E6 and E7 oncoproteins from six uncharacterized beta HPVs (14, 22, 23, 24, 36,49). Only HPV49 E6 and E7 immortalized primary human keratinocytes and efficiently deregulated the p53 and pRb pathways. Furthermore, HPV49 E6, similarly to E6 from the oncogenic HPV16, promoted p53 degradation.
