Using luciferase reporter assays, we showed that mdv1-miR-M4-5P and miR-155 efficiently targeted a common set of 3'untranslated regions (3'UTR) of six cellular genes (GPM6B, RREB1, c-Myb, MAP3K7IP2, PU.1[SPI1] and C/EBP).
An overview of known targets of cellular or viral targets is given in tables 2 and 3.Table 2 Cellular Targets of viral miRNAs.Table 3 Viral Targets of viral miRNAs.
As may be observed, we detected significant and selective repression of FLuc expression mediated by these 3'UTRs that was partially or entirely alleviated by mutation of the predicted miR-M4/miR-155 target sites.
