Growth-promoting properties of Epstein-Barr virus EBER-1 RNA correlate with ribosomal protein L22 binding.
The Epstein-Barr virus (EBV)-encoded RNAs, EBER-1 and EBER-2, are highly abundant noncoding nuclear RNAs expressed during all forms of EBV latency. The EBERs have been shown to impart significant tumorigenic potential upon EBV-negative Burkitt lymphoma (BL) cells and to contribute to the growth potential of other B-cell lymphoma-, gastric carcinoma-, and nasopharyngeal carcinoma-derived cell li...
متن کاملBinding of Epstein-Barr virus small RNA EBER-1 to the double-stranded RNA-activated protein kinase DAI.
Epstein-Barr virus encodes two small RNAs, EBER-1 and -2, that are abundantly expressed in latently infected cells. Recent evidence suggests a role for EBER-1 in regulation of translation since this RNA is able to prevent the inhibition of protein synthesis by double-stranded RNA in rabbit reticulocyte lysates. We show here that EBER-1 that has been synthesized in vitro forms a complex with the...
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...
متن کاملClusters of Basic Amino Acids Contribute to RNA Binding and Nucleolar Localization of Ribosomal Protein L22
The ribosomal protein L22 is a component of the 60S eukaryotic ribosomal subunit. As an RNA-binding protein, it has been shown to interact with both cellular and viral RNAs including 28S rRNA and the Epstein-Barr virus encoded RNA, EBER-1. L22 is localized to the cell nucleus where it accumulates in nucleoli. Although previous studies demonstrated that a specific amino acid sequence is required...
متن کاملReplacement of the Epstein-Barr virus plasmid with the EBER plasmid in Burkitt's lymphoma cells.
Transfection of an Epstein-Barr virus (EBV)-encoded plasmid containing EBER caused a substantial decrease in the level of plasmid containing EBV in Akata and Mutu Burkitt's lymphoma (BL) lines, but failed to do so in other BL lines. The results suggest that EBER could replace the role of EBV, but other EBV products also play a role in the growth of BL.
