MicroRNAs (miRNAs) regulate gene expression by targeting mRNA at specific sites in the 3 ́UTR, thereby inducing cleavage of the targets or inhibiting translation. The interaction of the miRNA with the target is mediated by an RNA-induced silencing complex (RISC), and depends on the sequence complementarity and the total number of binding sites in a given 3 ́UTR. Thus, to understand the roles of miRNA in complex biological processes, it is important to experimentally assess the functional relevance of the predicted miRNA targeting sites.
Cell assays based on the luciferase reporter gene can be adapted for testing the effect of miRNA-mediated, post-transcriptional regulation on target genes. As shown (Figure 1), the experimental procedure first consists in cloning both the wild-type and mutant forms of the 3'UTR of the miRNA predicted mRNA target downstream of a firefly luciferase reporter. Next, each construct is co-transfected together with the miRNA into suitable cell line, and the reporter expression is monitored. Changes in luciferase levels will indicate whether or not a miRNA can bind to the UTR and regulate its expression.
