A new plasmid-based microRNA inhibitor system (PMIS) effectively inhibits microRNA (miR) activity in cells and mice. In this study, researchers generated a novel RNA-based hairpin molecule carrying an anti-sense miR seed sequence that effectively knocks down endogenous miRs and mitigates their effects on messenger RNA in the cell. By using a native RNA-based molecule for miR knockdown, the PMIS platform avoids many of the traditional pitfalls associated with miR inhibition using synthetic oligonucleotides.
