Abstract: The objective of the study was to construct the eukaryotic expression vector of bovine GDF-9 gene,and investigate its effect on the expression of expansion-related genes in transfected bovine cumulus cells.Eukaryotic expression vector plasmid pcDNA4 myc-his-GDF-9 was constructed by insert GDF-9 in the multiple cloning site.pcDNA4 myc-his-GDF-9 was transfected into bovine cumulus cells by liposome.The expression of GDF-9 gene was detected by Western blotting and the expression of the expansion-related genes in bovine cumulus cells was detected by qRT-PCR.The results showed that GDF-9 could express in transfected bovine cumulus cells and the expression of expansion-related genes PTGS2,PTX3 and HAS2 in transfected bovine cumulus cells were significantly increased (P< 0.05).In a conclusion,the bovine pcDNA4 myc-his-GDF-9 could effectively transfected into bovine cumulus cells,which could help to study farther functions of the GDF-9 gene.
