Scientists have done a genetic modification of the chickens in order to set up eggs containing high quality drugs in the fight against cancer and arthritis, during the last medical advance.
Scientists at the Roslyn Institute of the University of Edinburgh believe that new technology can offer a cost-effective way to produce drugs in the near future.
By genetically modifying the chicken to produce drugs in the eggs, scientists discovered that the drugs worked like those produced using conventional methods.
Surprisingly, only three eggs were sufficient to produce the prescribed doses of the drug, and genetically modified chickens were able to put 300 eggs a year.
Professor Helen Sang stated that the team did not produce drugs for patients, but that the study provides preliminary evidence of the viability of the system and the possibility of configuring it to produce drugs. other therapeutic proteins.
The results of the study indicate that "chicken is commercially viable for the production of high quality drugs for research studies and other applications of biotechnology".
Eggs are already used in the culture of viruses used as vaccines, as in the influenza vaccine.
But in the new study, this sounds different because therapeutic proteins are encoded in chicken DNA and produced in egg whites.
The team of scientists was initially interested in a therapeutically important immune system protein called IFNalpha2a, with powerful antiviral and anticancer effects, as well as its human and porcine version, called macrophage-CSF, which stimulates repairing damaged tissues.
"We are excited to be developing this technology to the maximum of its potential, not only for future human treatments, but also for research and animal health," said Dr. Lisa Heron, Head of Roslin's Bioscience Unit. technologies.
