We already knew about presence of genetically modified ingredients in our food and also that animals were being gene-edited feed, but now animals too are being altered for human benefit. Researchers have modified the gene of chickens so as to make them lay eggs that will have drugs to treat patients with cancer and arthritis. The researchers have ensured the egg whites have two proteins that are essential to the immune system and have therapeutic potential.
IFNalpha2a, which has powerful antiviral and anti-cancer effects and macrophage-CSF, which is being developed as a therapy that stimulates damaged tissues to repair themselves. Researchers found that this method is expected to be 100 times cheaper than producing the drugs in factories and chickens are best suited to produce the drug.
