For each of them, direct interactions between 3'UTR and EBV miRNAs were confirmed by luciferase assay but no functional assay has been performed so far (Table 2).Table 2 Validated targets from high-throughput studies. Shown are cellular targets identified by photoactivatable ribonucleoside enhanced crosslinking and immunoprecipitation (PAR-CLIP), High-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP) or RNA immunoprecipitation and microarray (RIP-Chip) techniques. Validation of these targets was done using luciferase reporter assays.
We selected three 3'UTRs (GUF1, NAT12, and SCRN1) that were identified as high confidence targets for miR-BHRF1-1 for further analysis by luciferase reporter assays.
