Abstract

Import of viral DNA into the nucleus is essential for the successful replication of DNA tumour viruses. To achieve this goal, viruses have adapted strategies to traverse the barriers between the plasma membrane and the nucleus of a host cell. Two DNA tumour viruses, simian virus 40 and adenovirus, achieve the nuclear-entry step in slightly different ways. SV40 DNA enters the nucleus through the nuclear pore complexes (NPCs) in apparently intact virions. By contrast, adenovirus particles dissociate near the NPC before the viral DNA is imported into the nucleus. In both cases, karyophilic protein components of the viruses appear to mediate nuclear entry of the viral genomes. In this article, we discuss how an understanding of the cell biology of virus entry can help us understand the process of nuclear transport.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
