Epstein-Barr virus with heterogeneous DNA disrupts latency.
By cloning the HR-1 Burkitt lymphoma line, we previously uncovered two distinct biological variants of nontransforming Epstein-Barr virus (EBV). The most commonly cloned variant has a low rate of spontaneous viral synthesis and is unable to induce early antigen in Raji cells (EAI-). A rare variant spontaneously releases virus which is capable of inducing early antigen in Raji cells (EAI+). Sinc...
متن کاملEpstein-Barr virus immortalization and latency.
Epstein-Barr virus infects human B lymphocytes. The interaction between the virus and these cells has been the subject of investigation for over three decades. Recent in vitro and in vivo studies, reviewed here, are revealing the mechanisms by which EBV induces and controls proliferation through the expression of six viral nuclear proteins and two plasma membrane proteins. This genetic program ...
متن کاملEpstein-Barr Virus DNA Replication
Epstein-Barr virus (EBV) and its close relatives are the only known viruses that have two fully independent systems for replicating their genomes, one that supports virus production during active or "lytic" infection, and a second one that operates during latent stages of infection to allow the circular viral genomes to be duplicated during each cell division cycle. Although EBV's system of lyt...
متن کاملGenome rearrangements activate the Epstein-Barr virus gene whose product disrupts latency.
A defective Epstein-Barr virus (EBV) containing a deleted and rearranged genome (het DNA) causes latent EBV to replicate. This activity maps to the 2.7-kilobase-pair WZhet fragment. The BZLF1 open reading frame, present within WZhet as well as in the standard viral BamHI Z fragment, encodes the protein ZEBRA, which induces viral replication. Using gene transfers into Burkitt lymphoma cells, we ...
متن کاملAssociation of Human Papilloma Virus and Epstein-Barr Virus with Ovarian Cancer in Shiraz, Southwestern Iran
Background & Objective: Ovarian cancer is one of the most common cancers amongst women. The association of Human papillomavirus (HPV) and Epstein-Barr virus (EBV) with ovarian cancer is inconclusive; therefore, the aims of this study were to evaluate the frequency of HPV and EBV in malignant, ...
