Abstract
microRNAs (miRNAs) comprise a class of non-coding RNAs (ncRNAs) that are involved in the regulation of gene expression. Experimental evidences support that miRNAs may act as inhibitors of the translation process, or to promote protein degradation or also in the target mRNA degradation. Although the mechanism is not fully elucidated, indeed miRNAs play important roles in a number of biolo…
