Mutant chickens lay eggs filled with cancer drugs
Scientists in Japan have genetically modified chickens to lay eggs containing drugs that have the potential to significantly reduce the cost of cancer treatment.
The eggs were developed using genome-editing technology to produce a protein called interferon, which is used to treat hepatitis, multiple sclerosis and malignant skin cancer.
Injecting it into cancer patients three times per week can prevent cancer cells from multiplying, while also boosting T cells to fight tumors. But the remedy is expensive: Current production of just a few micrograms of interferon costs between $250 and $900.
