Analysis of JC virus DNA replication using a quantitative and high-throughput assay.

abstract：:We recently reported the phenomenon of retroviral insertion into a herpesvirus (Isfort et al., (1992) Proc. Natl. Acad. Sci. USA 89, 991-995). We have now isolated Marek's disease virus (MDV) clones that carry retroviral inserts. Retroviral LTR insertion has the potential to activate or inactivate herpesvirus genes le...
