The role of genes of the Argonaute family in the effects of the RNA interference activator enoxacin on the lifespan of Drosophila melanogaster

Epigenetic mechanisms play a leading role in the regulation of gene expression and the coordination of biological processes, influencing the aging rate and the organism’s lifespan. An important role in the implementation of these mechanisms is played by small RNAs which suppress the activity of own targets through the RNA interference and provide the antiviral protection. Enoxacin is a unique inducer of RNA interference factors with potential geroprotective activity. Its effects have been identified to be mediated by miRNAs but other types of non-coding RNAs may also be involved. In this study, we have investigated the effect of enoxacin on the Drosophila melanogaster lifespan and first analyzed the contribution of Argonaute family genes to this effect which specifically ensure the biogenesis and functioning of miRNAs, siRNAs, and piRNAs.
