人类乳头瘤病毒的贝塔属感染皮肤角质形成细胞。它们的复制依赖于活跃的增殖细胞,因此,它们与细胞对这些细胞经常遇到的DNA损伤的反应相冲突。这篇综述集中在其中一种病毒(HPV8),它通过表达一种蛋白质(HPV8 E6)来破坏组蛋白乙酰转移酶p300的稳定,从而对抗细胞对DNA损伤和有丝分裂错误的反应。P300的丢失导致细胞信号的广泛失调,从而降低了基因组的稳定性。除了讨论p300失稳引起的表型外,该综述还讨论了来自其他β-HPV的E6对p300失稳的程度,并提供了使用突变体解剖HPV8E6生物学的讨论。
The beta genus of human papillomaviruses infects cutaneous keratinocytes. Their replication depends on actively proliferating cells and, thus, they conflict with the cellular response to the DNA damage frequently encountered by these cells. This review focus on one of these viruses (HPV8) that counters the cellular response to damaged DNA and mitotic errors by expressing a protein (HPV8 E6) that destabilizes a histone acetyltransferase, p300. The loss of p300 results in broad dysregulation of cell signaling that decreases genome stability. In addition to discussing phenotypes caused by p300 destabilization, the review contains a discussion of the extent to which E6 from other β-HPVs destabilizes p300, and provides a discussion on dissecting HPV8 E6 biology using mutants.
