Abstract: This study aims to construct the expression plasmid of BMP4 gene in AoHan sheep and explore the change of gene expression after transfection of fibroblasts. 30-day old AoHan sheep embryos were selected as the research subject. Firstly, a pair of primers was designed by reverse transcribing RNA into cDNA based on the sequence of BMP4 in GenBank. The BMP4 gene fragment was amplified by PCR reaction, and was ligated into pEASYTM-T1 vector to construct pEASYTM-T1-BMP4 recombinant plasmid, which was transformed into E.coli DH5α competent cells to extract the plasmid for restriction enzyme digestion. Then the fibroblasts of AoHan sheep were isolated and cultured, and the constructed plasmid pcDNA3.1-BMP4 was transfected into fibroblasts. The expression of BMP4 gene in fibroblasts was detected by quantitative PCR and Western Blot. The results showed that plasmid pcDNA3.1-BMP4 was successfully constructed by restriction enzyme digestion and sequencing, and BMP4 gene expression was significantly increased after transfection of fibroblasts. The expression level of transfection group was significantly higher than that of the control group. The plasmid was constructed and transfected into fibroblasts successfully. The result can be a basis for further study of its function.
