micro RNA application to livestock

Post-transcriptional gene regulation guided by micro RNAs has emerged as one of the major gene regulatory mechanisms in higher eukaryotes, micro RNAs regulate gene translation through the recognition of complementary sequences between micro RNAs and their target genes. Recent studies in livestock have revealed that many micro RNAs are species- and tissue-speci?c, indicating that micro RNAs play important roles in essential physiological processes in livestock, such as metabolism, and muscle and organ development. It is anticipated that many micro RNAs will be linked to phenotypic differences or quantitative trait variations of livestock. The role of micro RNA in developmental decisions that affect animal biology is of significant interest, yet the current literature on livestock models is limited. In this review, we summarize the current micro RNA studies undertaken in livestock.
