ObjectivesOmega-3 polyunsaturated fatty acids (n-3 PUFAs) are beneficial to human health. However, the n-3 PUFAs contents of the livestock meat that we consume daily are relatively low. Utilization of transgenic technology to increase n-3 PUFAs contents in livestock may solve this problem.ResultsThe omega-3 fatty acid desaturase (FAD3), encoded byfat1gene derived fromCaenorhabditis elegans(C. elegans), converts omega-6 polyunsaturated fatty acids (n-6 PUFAs) to n-3 PUFAs. In the study, a plasmid containing the codon-optimizedC. elegansfat1gene (mfat1) was constructed and used to produce transgenic beef cattle by somatic cell nuclear transfer. Fourteen transgenic calves were obtained, and the ratio of n-6 to n-3 PUFAs in the transgenic calves decreased from 5.33: 1 to 0.95: 1 compared with negative controls.ConclusionsOur results demonstrated that the codon-optimizedC. elegansmfat1gene can be functionally expressed in the beef cattle and converts n-6 PUFAs to n-3 PUFAs.
