The Epstein-Barr virus (EBV)-encoded latency protein Epstein-Barr nuclear antigen 2 (EBNA2) is a nuclear transcriptional activator that is essential for EBV-induced cellular transformation. In a previous study, we demonstrated that EBNA2 interacts with signal transducer and activator of transcription 3 (STAT3), a signal transducer for an interleukin (IL)-6 family cytokine, and enhances its tran...
The crystal structure of the DNA-binding and dimerization domains of the Epstein-Barr virus nuclear antigen 1 (EBNA1), which binds to and activates DNA replication from the latent origin of replication in Epstein-Barr virus, was solved at 2.5 A resolution. EBNA1 appears to bind DNA via two independent regions termed the core and the flanking DNA-binding domains. The core DNA-binding domain, whi...
Epstein-Barr virus is associated with several human malignancies including Burkitt's lymphoma, nasopharyngeal carcinoma, and Hodgkin's disease (HD). To examine the effect of Epstein-Barr virus nuclear antigen 1 (EBNA-1) in the pathogenesis of HD, we transfected the gene into the HD cell line L428. EBNA-1 expression was associated with significantly enhanced CD25 expression (interleukin 2 [IL-2]...
Multiple methods, pedigree analysis, clinical evaluation, and Epstein-Barr virus (EBV)-specific serology, EBV DNA hybridization of tissues to probe for viral genome, staining of touch imprints for EBV nuclear-associated antigen, establishment of spontaneous infected B-cell lines from peripheral blood or tissues, examination of peripheral blood smears, and hematopathology studies, were used to s...
