Big from Small: MicroRNA in Relation to Veterinary Sciences

Eukaryotic transcriptome sequence data reveals that majority of the genome is transcribed into distinct noncoding RNA species, called microRNAs (miRNA). The miRNA is subset of tiny noncoding RNAs, about 21–23 nucleotides long, that play a role in controlling cognate mRNA degradation by cleavage or inhibiting the translational process. miRNA is popularly referred to as “micromanager of gene regulation.” In humans, miRNA disruption is correlated to diseases like cancers. In addition, miRNA has important implications in diseases and biological processes such as development, memory establishment, cell proliferation, apoptosis, and infections. Knowledge acquired from understanding miRNA pathway should be exploited to design artificial miRNAs with potential uses in therapeutics and livestock development.
miRNAs are abundantly present in many organisms
The impact of miRNA-driven gene regulation is enormous; hence, it is a key field of study
In view of their involvements in diseases and biological processes, miRNAs offer opportunities to develop curative interventions.
