Background:

MicroRNAs (miRNAs) are small noncoding RNAs regulating gene expression in plants and animals.
miRNAs function by binding to target messenger RNAs (mRNAs), influencing translation and stability.
Identifying specific miRNA-mRNA interactions is essential for understanding miRNA biological roles.

Purpose of the Study:

To develop and validate a novel reporter assay for identifying miRNA targets.
To establish a robust method for determining bona fide miRNA binding sites in mRNAs.
To facilitate the experimental validation of bioinformatically predicted miRNA-mRNA interactions.

Main Methods:

A fluorescence intensity-based reporter assay was developed.
Transient delivery techniques in zebrafish were employed for assay component introduction.
