Abstract MicroRNAs miRNAs are small RNAs of 2l-25 nucleotides that specifically regulate cellular gene expression at the post-transcriptional level. miRNAs are derived from the maturation by cellular RNases III of imperfect stem loop structures of 70 nucleotides. Evidence for hundreds of miRNAs and their corresponding targets has been reported in the literature for plants insects invertebrate animals and mammals. While not all of these miRNA target pairs have been functionally verified some clearly serve roles in regulating normal development and physiology. Recently it has been queried whether the genome of human viruses like their cellular counterpart also encode miRNA. To date there has been only one report pertaining to this question. The Epstein-Barr .
