Notch1, Notch2, and Epstein-Barr virus-encoded nuclear antigen 2 signaling differentially affects proliferation and survival of Epstein-Barr virus-infected B cells.
The canonical mode of transcriptional activation by both the Epstein-Barr viral protein, Epstein-Barr virus-encoded nuclear antigen 2 (EBNA2), and an activated Notch receptor (Notch-IC) requires their recruitment to RBPJ, suggesting that EBNA2 uses the Notch pathway to achieve B-cell immortalization. To gain further insight into the biologic equivalence between Notch-IC and EBNA2, we performed ...
متن کاملActivated Notch1 modulates gene expression in B cells similarly to Epstein-Barr viral nuclear antigen 2.
Both Epstein-Barr viral nuclear antigen 2 (EBNA2) and activated Notch transactivate genes by interacting with the transcription factor RBP-Jkappa. The viral protein EBNA2 may hence be regarded as a functional equivalent of an activated Notch receptor. Until now, nothing has been known about the physiological role of Notch signaling in B cells. Here we investigated whether activated Notch can in...
متن کاملEpstein-Barr viral nuclear antigen 1 antisense oligodeoxynucleotide inhibits proliferation of Epstein-Barr virus-immortalized B cells.
The Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA-1) is a latent viral protein that is expressed in all EBV-immortalized lymphocytes and plays an essential role in immortalization y EBV. EBNA-1 protein is required for replication and maintenance of the episomal viral genome in latently infected, immortalized cells. Given the essential function of EBNA-1 in immortalization, we have examined t...
متن کاملU2 region of Epstein-Barr virus DNA may encode Epstein-Barr nuclear antigen 2.
Sequence analysis of the U2 regions of the B95-8 and AG876 Epstein-Barr virus (EBV) isolates reveals divergence within a long open reading frame previously identified as encoding 1.5 kilobases of the 3' end of a viral RNA expressed in latently infected, growth-transformed, B-lymphocyte cell lines. Differences among EBV isolates within the U2 open reading frame are shown to correlate with differ...
متن کاملTHE IN VITRO GROWTH PROPERTIES OF CELL LINES FROM EPSTEIN-BARR VIRUS-INDUCED TAMARIN TUMORS AND TAMARIN B CELLS TR ANSFORMED BY EPSTEIN BARR VIRUS
EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...
