高危人乳头瘤病毒(HPV)导致宫颈癌和其他肛门生殖器癌,并且它们也与头颈部鳞状细胞癌(HNSCC)的一个子集有病因联系。我们先前建立了HPV相关HNSCC模型,其中我们用化学致癌物4-硝基喹啉-1-氧化物(4-NQO)处理表达乳头瘤病毒癌蛋白的转基因小鼠。我们发现HPV-16 E7癌蛋白在引起HNSCC中是高度有效的,并且其优势掩盖了E6的任何潜在致癌作用,E6是人类癌症中通常表达的第二种乳头瘤病毒癌蛋白。在目前的研究中,我们缩短了4-NQO治疗的持续时间,以降低癌症的发病率,并发现E6和E7在引起HNSCC方面具有惊人的协同作用。在HNSCC模型中比较野生型与突变型E6基因的致癌特性,发现了E6的一些而不是其他细胞靶点在宫颈癌中的作用。
High-risk human papillomaviruses (HPVs) contribute to cervical and other anogenital cancers, and they are also linked etiologically to a subset of head and neck squamous cell carcinomas (HNSCC). We previously established a model for HPV-associated HNSCC in which we treated transgenic mice expressing the papillomaviral oncoproteins with the chemical carcinogen 4-nitroquinoline-1-oxide (4-NQO). We found that the HPV-16 E7 oncoprotein was highly potent in causing HNSCC, and its dominance masked any potential oncogenic contribution of E6, a second papillomaviral oncoprotein commonly expressed in human cancers. In the current study, we shortened the duration of treatment with 4-NQO to reduce the incidence of cancers and discovered a striking synergy between E6 and E7 in causing HNSCC. Comparing the oncogenic properties of wild-type versus mutant E6 genes in this model for HNSCC uncovered a role for some but not other cellular targets of E6 previously shown to contribute to cervical cancer.
