Abstract: We describe the construction of a self-replicating form of microRNA (miRNA) and demonstrate its amplification and biological activity in cultured cells. In typical embodiments, a miRNA sequence of interest is flanked by self-cleaving ribozymes and added to RNAl of the Nodamura virus, which is directly translated to generate an RNA-dependent-RNA-polymerase that replicates it strongly along with the doubly-self-cleaving ribozyme cassette containing the miRNA. In the specific case of miR-34a flanked by Hammerhead and Tetrahymena ribozymes, BHK-21 cells transfected with the replicon form of this cassette are shown to generate up to one million copies/cell of the miRNA. The biological activity of this amplified miR-34a is demonstrated by the essentially complete apoptosis of cultured prostate cancer cells transfected with the replicon.
