According to Japanese media reports on September 18, Japanese scientists have succeeded in cultivating a new type of hen that can produce millions of dollars worth of "golden eggs" because it contains an expensive protein. It can be used to treat serious diseases such as cancer and hepatitis.

The scientists from the National Institute of Advanced Industrial Science and Technology and the Japan Institute of Biomedical Research have invented this novel "golden egg" production method. Scientists use new genome editing techniques to transform hens, and hens can produce eggs containing large amounts of interferon at a lower cost. Previously, the traditional method of artificial interferon beta based on colonic or cultured cells required the use of huge dedicated facilities at a very high cost.

The scientists first performed cell collection, and the cells from the cock embryos were eventually transformed into sperm. The scientist then implants a gene that produces human interferon beta. After completing the above procedure, the cells were returned to the embryos of other small cocks, and the hatched cocks were used to mate with the wild hens. The researchers found that eggs hatched by their female offspring contain high levels of human interferon beta, which can be found in proteins around the egg yolk.

This protein content in a single egg ranges from about 30 to 60 mg, considering the market price of human interferon beta, the value of each egg It is estimated to be between $530,000 and $2.6 million. Human interferon beta is a natural antiviral protein that is very expensive and is commonly used as a therapeutic agent for diseases such as cancer and hepatitis. Xiaobian searched the price of artificial interferon B on the domestic website and found that the price of a related drug of 1.5 mg was also three or four thousand.

Scientists are currently working with a Japanese reagent manufacturing company, Cosmo Bio, to explore the feasibility of commercializing hens to hatch antiviral proteins. Cosmo Bio plans to begin selling the protein produced by the company's internal hens early next year, mainly for medical research purposes, and hopes to commercialize it in the future.

Cosmo Bio's Kitahara Miyuki told the media: About interferon-beta protein, about 20 hens in our company can produce this kind of "gold" Eggs, so far, our hens are constantly producing eggs, just like normal hens. She emphasized the benefits of this technology and added that these hens can continue to lay eggs, so we can get a lot of recombinant protein stably. In addition, this mechanism will not kill hens.

More important The company said that if the drug is developed according to the new method, the price will be half or one-third of the traditional drug. This is really a boon for patients with serious diseases. Before it was officially sold as a drug, its Validity and safety must be confirmed. The company's next step is to make the test based on the protein produced by the hen and perform more tests.
