Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) are essential components required for normal cellular function and have been shown to have important therapeutic and nutritional benefits in humans. But humans or mammals cannot naturally produce ω-3 PUFAs, due to the lack of the ω-3 fatty acid desaturase gene (fat-1 gene). Previously, fat-1 gene has been cloned from Caenorhabditis elegans and transferred into mice, pigs and sheep, but not yet into beef cattle. We attempt to transfer it into beef cattle. The object of this paper is to edit the fat-1 gene from C. elegans to express more efficiently in beef cattle and verify its biological function in mice model. As a result, the fat-1 gene from C. elegans was modified by synonymous codon usage and named it Bfat-1. We have demonstrated that degree of codon bias of Bfat-1 gene was increased in beef cattle. Moreover, Bfat-1 gene could be transiently expressed in mouse liver and muscle, the ω-6/ω-3 PUFAs ratio of 18 and 20 carbon was decreased significantly in liver (P |
