Circular RNAs (circRNAs) are covalently closed and single-stranded transcripts that are produced from precursor mRNA back splicing in eukaryotes. The improvements in high-throughput RNA sequencing and novel bioinformatics tools have led to the identification of thousands of circRNAs in various organisms. Recent findings have indicated that circRNAs may interact with RNA or proteins and serve as transcription or splicing regulators. Particularly, circRNAs have been found to interact with microRNA (miRNA) and function as miRNA sponges. Therefore, it is important to experimentally validate the predicted miRNA and detail binding sites for circRNA mechanism research.
The luciferase reporter assay is commonly used as a tool to study gene expression at the transcriptional level. It also can be utilized to investigate the regulation miRNA complementary to specific circRNA. As shown (Figure 1), the luciferase vector (such as psiCHECK2) is constructed by inserting the specific circRNA sequence in the 3' UTR into the promoter-driven luciferase reported gene. Cells are co-transfected with the luciferase reporter vector and the miRNA mimics in order to establish the characteristic of circRNA as miRNA sponges by comparing the luciferase activity with the negative controls. Similarly, mutant circRNA sequence could be cloned into luciferase vector to verify the detail binding sites interacted with miRNA.
