Abstract: In order to explore the relationship between miR-143 and its interacted lncRNA and its mechanism in the process of bovine myogenic differentiation, two predicted highly expressed(lncRNA lncRNA-HZ5 and lncRNA-HZ8)were chosen for further research. The relationship between miR-143 and predicted interacted lncRNA were identified by dual-luciferase assay and qRT-PCR detection, the influence of lncRNA on the protein level of miR-143’s target gene was detected by western blot. The results showed that lncRNA-HZ5 was directly regulated by miR-143 using dual-luciferase assay. The expression of lncRNA-HZ5 was significantly down-regulated when miR-143 was over expressed, and significantly up-regulated when miR-143 was inhibited. It was found that inhibition of lncRNA-HZ5 expression using siRNA could down-regulate miR-143 and up-regulate the protein level of miR-143’s target gene IGFBP5. The results showed that the miR-143 could interact with lncRNA-HZ5 in bovine skeletal muscle satellite cells, which indicated that miR-143 may regulate the bovine myogenic differentiation by interacting with lncRNA-HZ5.
