目的Omega-3多不饱和脂肪酸(n-3 PUFAs)对人体健康有益。然而,我们日常食用的畜禽肉中n-3 PUFAs的含量相对较低。利用转基因技术提高家畜n-3 PUFAs含量可能解决这一问题。elegans)将ω-6多不饱和脂肪酸(n-6 PUFA)转化为n-3 PUFA。在这项研究中,含有密码子优化的C.本研究构建了elegansfat 1基因(mfat 1),并利用体细胞核移植技术制备了转基因肉牛。获得14头转基因犊牛,与阴性对照相比,转基因犊牛中n-6与n-3 PUFAs的比例从5.33:1下降到0.95:1。elegansmfat 1基因在肉牛中可功能性表达,并将n-6 PUFAs转化为n-3 PUFAs。
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.
