There are various tools available for target micro RNA prediction.- miRDB is an online database for miRNA target prediction and functional annotations. All the targets in this case were predicted by a bioinformatics tool, Currently available and frequently used computational tools for miRNA target prediction, i.e., PicTar, TargetScan, DIANA-microT, miRanda, rna22 andPITA are outlined and various practical aspects of miRNA target analysis can be looked through internet as finding a suitable functional microRNA tool is really challenging
