Genetically modified chickens may help with cancer
UK researchers have developed genetically modified
chickens that can lay eggs which contain the proteins required to develop
Birds at the Roslin
, near Edinburgh (Scotland), had been modified to lay eggs which
contain miR24â€”an antibody that has the potential to treat skin cancerâ€”and others
produce human interferon b-1a
â€”which can be used to stop viruses from
replicating in cells.
The institute claims it produced five generations of chickens that can
produce useful levels of proteins for the development of life-saving cancer
drugs in their eggs. The proteins are secreted into the egg whites, and can then
be extracted and purified.
"The idea of producing the proteins involved in treatments of flocks of
laying hens means they can produce in bulk, they can produce cheaply and indeed
the raw material for this production system is quite literally chicken
The Roslin Institute is the same research centre that first cloned a sheep,
