The functional effect of a specific miRNA is tightly linked to the transcriptome, thus having the potential to elicit distinct outcomes in different cellular states. Our recent discovery of a dual role of the miR-17-92 cluster, which shifts from oncogene to tumor suppressor during lymphoma progression, exemplifies the spatiotemporal plasticity of miRNAs.
