Micro RNA s mir‐184 and let‐7 alter Drosophila metabolism and longevity

MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression associated with many complex biological processes. By comparing miRNA expression between long-lived cohorts of Drosophila melanogaster that were fed a low-nutrient diet with normal-lived control animals fed a high-nutrient diet, we identified miR-184, let-7, miR-125, and miR-100 as candidate miRNAs involved in modulating aging. We found that ubiquitous, adult-specific...
