Research Abstract

The expression profile of viral microRNAs in EBV-associated gastric carcinoma was analysed using quantitative RT-PCR analysis. Compared with the previous reports on the expression profile of other EBV-associated tumors, some viral microRNAs were specifically upregulated in EBV-associated gastric carcinoma. In vitro analysis revealed that one of these micro RNAs targets a gene that is known to facilitate apoptosis of the cells, and that it subsequently leads to the immortality of tumor cells.
