Generation of cloned transgenic pigs rich in omega-3 fatty acids

Nat Biotechnol. 2006 Apr;24(4):435-6. doi: 10.1038/nbt1198. Epub 2006 Mar 26.


Meat products are generally low in omega-3 (n-3) fatty acids, which are beneficial to human health. We describe the generation of cloned pigs that express a humanized Caenorhabditis elegans gene, fat-1, encoding an n-3 fatty acid desaturase. The hfat-1 transgenic pigs produce high levels of n-3 fatty acids from n-6 analogs, and their tissues have a significantly reduced ratio of n-6/n-3 fatty acids (P < 0.001).
