Russian and Belarusian researchers join hands to cultivate genetically modified goats
Milk transfer protein is a very important protein in breast milk. When the baby is born, milk protein content in breast milk can reach 6 grams per liter. The protein has a strong anti-oxidation, can protect infants from disease interference, improve the baby's immune system, and plays an important role in infants' growth and development. The Institute of Genetics and Biotechnology of the Russian Academy of Sciences and the Animal Science Research Institute of the Belarusian National Academy of Sciences are actively collaborating to develop genetically engineered female goats containing human genes in order to obtain large quantities of transgenic goat milk containing milk-transport proteins. Researchers from Russia and Belarus have jointly developed a method for obtaining the structure of milk transfer protein genes and conducted experiments in rats. As a result, it was found that the milk secreted by the experimental mice contained a large amount of milk-transporting protein, which increased by 40 g each. At present, researchers are studying the technical process of implanting human milk transfer protein gene structures into goat fertilized eggs, and then transplant these fertilized egg cells into goats. If the experiment is successful, the transgenic goats produced will be able to secrete milk containing human milk proteins. The researchers said that the reason why goats were selected as experimental subjects was that goats were mild and their gestation period was short; in addition, the use of human proteins was safe and efficient, and did not cause allergic reactions. It is reported that researchers plan to transfer human breast milk to more than 100 goats to deliver protein and establish a pilot plant in Minsk, Belarus. It is planned that by 2007, the mass production of genetically modified goat milk will be realized. Relevant experts pointed out that if the experiment is successful, it will greatly improve the quality of goat milk. Goat milk will become an important material for the treatment of cardiovascular diseases, and it can also be the best milk product for artificial feeding of infants. It can also be delivered in milk. Protein based on the production of antimicrobial drugs.
