人乳头瘤病毒(HPV)引起大量的人类疾病,从良性疾病如疣到恶性癌症,包括宫颈癌、头颈癌和非黑色素瘤皮肤癌。我们对HPV诱导的恶性疾病建模的能力受到物种特异性障碍的阻碍,并且临床前动物模型的开发一直具有挑战性。最近发现的鼠乳头状瘤病毒,MmuPV1,感染实验室小鼠,并导致相同范围的恶性肿瘤引起的HPV提供了乳头状瘤病毒领域的机会,以测试机制的假设,在一个遗传操纵的实验室动物物种的背景下,自然感染。由高危HPV编码的E6和E7蛋白是与人类癌症相关的HPV基因型,是以多种方式促成HPV诱导的癌症的多功能蛋白。在这篇综述中,我们描述了MmuPV1编码的E6和E7蛋白的已知活动,以及这些活动如何与粘膜和皮肤高危HPV基因型编码的HPV E6和E7癌蛋白的活动相关。
Human papillomaviruses (HPVs) cause a substantial amount of human disease from benign disease such as warts to malignant cancers including cervical carcinoma, head and neck cancer, and non-melanoma skin cancer. Our ability to model HPV-induced malignant disease has been impeded by species specific barriers and pre-clinical animal models have been challenging to develop. The recent discovery of a murine papillomavirus, MmuPV1, that infects laboratory mice and causes the same range of malignancies caused by HPVs provides the papillomavirus field the opportunity to test mechanistic hypotheses in a genetically manipulatable laboratory animal species in the context of natural infections. The E6 and E7 proteins encoded by high-risk HPVs, which are the HPV genotypes associated with human cancers, are multifunctional proteins that contribute to HPV-induced cancers in multiple ways. In this review, we describe the known activities of the MmuPV1-encoded E6 and E7 proteins and how those activities relate to the activities of HPV E6 and E7 oncoproteins encoded by mucosal and cutaneous high-risk HPV genotypes.
