MicroRNAs in model and complex organisms

Abstract

Non-coding RNAs such as microRNAs (miRNAs) are very tiny ribonucleotides having an essential role in gene regulation at both post-transcriptional and translational levels. They are very conserved and expressed in worms, flies, plants, and mammals in a sequence-specific manner. Furthermore, it is now possible to clone miRNAs using the new genome editing tool CRISPR/cas9, which shows benefit in control of untargeted effect. In this special issue, we tried to cover researches associated with functional roles of miRNAs accross model and complex organisms.
