Epstein-Barr Nuclear Antigen 1 Contributes to Nasopharyngeal Carcinoma through Disruption of PML Nuclear Bodies
Latent Epstein-Barr virus (EBV) infection is strongly associated with several cancers, including nasopharyngeal carcinoma (NPC), a tumor that is endemic in several parts of the world. We have investigated the molecular basis for how EBV latent infection promotes the development of NPC. We show that the viral EBNA1 protein, previously known to be required to maintain the EBV episomes, also cause...
متن کاملStudy of Epstein-Barr virus nuclear antigen (EBNA-1) variations: V-val type preferentially exists in biopsies of nasopharyngeal carcinoma from Vietnamese patients
Background: Epstein-barr virus nuclear antigen 1 (EBNA1) plays a crucial role in Nasopharyngeal carcinoma (NPC), the most common cancer of head and neck cancer in Asian countries with high incidents. Sequence variations are of high frequency within the functionally important domains of EBNA-1, which have been classified into five subtypes: Phenotype (P)-ala, P-thr, V-val, V-leu and V-pro and ar...
متن کاملThe Epstein-Barr virus-encoded nuclear antigen EBNA-5 accumulates in PML-containing bodies.
EBNA-5 is one of the Epstein-Barr virus (EBV)-encoded nuclear proteins required for immortalization of human B lymphocytes. In the nuclei of EBV-transformed lymphoblastoid cell lines EBNA-5 is preferentially targetted to distinct nuclear foci. Previously we have shown (W.Q. Jiang, L. Szekely, V. Wendel-Hansen, N. Ringertz, G. Klein, and A. Rosen, Exp. Cell Res. 197:314-318, 1991) that the same ...
متن کاملEpstein-Barr Virus Nuclear Antigen 1
Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA1)--the one EBV antigen that is expressed in all EBV-associated malignancies--has long been thought to go undetected by the cell-mediated immune system. However, recent studies show that EBNA1 can be presented to both CD4+ and CD8+ T cells, making it a potential new target for immunotherapy of EBV-related cancers.
متن کاملEvaluation of antibodies against different Epstein-Barr virus nuclear antigen 1 peptides in diagnosis of nasopharyngeal carcinoma.
Epstein-Barr virus nuclear antigen 1 (EBNA1) is a protein expressed consistently in nasopharyngeal carcinoma (NPC). Although antibody levels against three different EBNA1 peptides were all high in NPC patients, the correlation between any two biomarkers was low. Therefore, the selection of distinct EBNA1 peptides could render different results in serological detection for individuals with NPC.
