Brazilian Research: Genetically Engineered Cow Produces Human Insulin, Potential Diabetes Cure

Researchers in Brazil have genetically modified cows to produce human insulin in their milk, potentially offering a breakthrough in diabetes treatment by alleviating insulin scarcity and making it more affordable. The study, led by a professor at the University of Illinois, successfully integrated a human DNA segment into cows' embryos, resulting in the production of milk containing both proinsulin and insulin. The goal is to create a herd of transgenic cows that can outpace current insulin production without the need for high-tech facilities, aiming to produce one gram of insulin per liter of milk.
