Abstract:

miR-423-5p has important biological functions in cells, for example, it can affect cell proliferation in myocytes. In this paper, homology analysis was performed based on the relevant information displayed on miRBase and NCBI websites using analysis software. Skeletal muscle, small intestine and heart tissues from adult Simmental cattle were taken for miR-423-5p expression assay using stem-loop real-time PCR, and the same assay was performed after differentiation of bovine skeletal muscle satellite cells (MDSCs) treated with different time. Finally, the possible binding target genes were predicted by online software (TargetScan, PicTar). The results showed that miR-423-5p had a high homology among species and significantly higher expressed in skeletal muscle than in other tissues. In MDSCs, miR-423-5p expression gradually increased as the differentiation time of cells increased. miR-423-5p contained potential binding sites on the 3'UTR of 12 gene mRNAs, some of the target genes were involved in cell proliferation, differentiation and apoptosis. The results suggested that miR-423-5p may be involved in cell growth metabolism and regulate cell proliferation and differentiation.
