Most people eat chicken eggs for their high protein content and healthy fats – but in the future eggs could ward off diseases, such as cancer and hepatitis. That’s because researchers at Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have genetically engineered chickens to lay eggs that contain drugs capable of boosting the immune system. The controversial technique was developed to make pharmaceutical drugs more affordable and, as a result, more accessible.
The researchers used gene editing technology to make chickens produce “interferon beta.” This protein is a “powerful tool” for treating skin cancer and hepatitis, reports Phys.org. The team produced cells that were used to fertilize eggs and breed hens that inherited the genes. A few rounds of cross-breeding yielded chickens capable of laying eggs containing the disease-fighting drugs.
As soon as next year, a joint research company will sell the drug to pharmaceutical companies so they can perform research on it at a reduced cost. “This is a result that we hope leads to the development of cheap drugs,” said Professor Hironobu Hojo, from Osaka. “In the future, it will be necessary to closely examine the characteristics of the agents contained in the eggs and determine their safety as pharmaceutical products.”
