Small non-coding RNAs have emerged as potent regulators of gene expression. Of the three classes - microRNA (miRNA), endogenous small interfering RNA (endo-siRNA) and Piwi-interacting RNA (piRNA), miRNA is the better understood system. Its main function is post-transcriptional repression of target genes. miRNAs are transcribed from individual genes or from the introns of intron-containing genes. The resulting primary miRNA transcript (pri-miRNA) contains a hairpin-loop structure with single str
