Abstract:

To study the target genes of miR-144 and their expression patterns in different tissues of cattle, and to predict the regulatory mechanism of miR-144 on muscle growth and development, the conservation, potential target genes and their enrichment pathways of miR-144 among different species were analyzed, and expression of miR-144 in different tissues of cattle was detected by qRT-PCR. The results showed that mature sequence of miR-144 was highly conserved among species; Enrichment analysis showed that target genes were significantly enriched in vascular smooth muscle contraction, cGMP-PKG, cAMP and other pathways related to muscle development. qRT-PCR results showed that miR-144 had the highest expression in liver and the lowest expression in subcutaneous fat; There was no significant difference(P>0.05) in the expression of miR-144 in leg muscle and heart, but the expression of miR-144 in liver was significantly (P<0.05) higher than that in leg muscle and heart; The expression of miR-144 in longissimus dorsi was significantly (P<0.05) higher than that in rumen and subcutaneous adipose, but there was no significant difference (P>0.05) between rumen and subcutaneous adipose.

Key words: miR-144, tissue expression, target gene prediction, qRT-PCR, enrichment pathway
