Abstract
Micro-RNAs (miRNAs) are an emerging class of small non-coding RNAs of 17 to 25 nucleotides in length implicated in a wide variety of cellular processes. MiRNAs posttranscriptionally repress gene expression by recognizing complementary target sites in the 3´ untranslated region (UTR) of target messenger RNAs (mRNA). Currently, although the number of genes known to be involved in muscle dis…
