Adenovirus and minute virus of mice DNAs are localized at the nuclear periphery.
The localization of adenovirus 2 (Ad2) and Minute Virus of Mice (MVM) DNAs was studied in situ in infected HeLa cell nuclei using fluorescent DNA probes and confocal microscopy. Ad2 DNA was found in multiple foci which were localized along the periphery of the infected cell nuclei. MVM DNA was found in HeLa cell nucleoli which are associated with the nuclear envelope, and when co-infected with Ad2 MVM DNA was compartmentalized to multiple foci which again were localized at the nuclear periphery. The data are discussed in terms of a model for the role of intranuclear compartmentalization in eukaryotic DNA structure and function.
