miRNAs (microRNAs) are a class of small endogenous non-coding RNAs, approximately 17-25 bp in length, which are able to participate in post-transcriptional regulation of genes by specifically binding to target mRNAs, causing their degradation or inhibiting their translation. miRNAs are involved in multiple regulatory pathways of genes, ranging from embryonic development, viral defense, hematopoietic processes, organ formation,
