Abstract
Previous studies indicated that miR-29c is important for muscle development in mice and human, but its role in pigs is unknown. In this study, we detected the expression of miR-29c in Meishan longissimus lumborum (LL) muscle. The results showed that miR-29c was gradually upregulated during development of skeletal muscle in pig. Moreover, the expression of and genes, which were confirmed to be targeted by miR-29c in mice, was decreased along with muscle development. Furthermore, the expression level of miR-29c was significantly higher in adult Meishan pigs than Large White pigs, while the expression of and genes was significantly lower in Meishan pigs. These results indicated that the expression pattern of miR-29c was opposite to that of and genes in pigs. Also, the luciferase assay indicated that miR-29s can target the gene in pigs. In addition, we identified a T to C mutation in the primary transcript of miR-29c, which was associated with the postmortem muscle pH in pigs. Based on these results, we concluded that miR-29c is also important in skeletal muscle development of pigs.
