Abstract
MicroRNAs (miRNAs) are small non-coding endogenous RNAs (~22 nucleotides) that have a potent action in the post-transcriptional regulation of gene expression, repressing translation by pairing in the 3' untranslated region (3'UTR) of the messenger RNA (mRNA) target. MicroRNAs are involved in the control of several biological processes related to tumorigenesis, such as cell differentiation…
