Review of the Different Outcomes Produced by Genetic Knock Out of the Long Non-coding microRNA-host-gene MIR22HG versus Pharmacologic Antagonism of its Intragenic microRNA product miR-22-3p.

From a therapeutic viewpoint, genetic inactivation of a lncMIRHG and pharmaco-logic antagonism of the guide strand of its related intragenic miRNA produce different results. This should be expected as lncMIRHGs play dual roles, both as lncRNA and as a source for primary miRNA transcripts.
