DOLLY SCIENTISTS CREATE CANCER-FIGHTING
CHICKEN EGGS

9:48 Sunday 3 December 2000

Scientists who cloned Dolly the Sheep have created designer chickens
whose eggs may help produce drugs to fight cancer.

They have altered the hens' genetic make-up so the whites of their eggs are
rich in tailored proteins which will form the basis of new drugs that could be
commercially available within two years, according to the Mail on Sunday.

Proteins in egg-white are produced according to instructions encoded in the
hen's genes. Altering the genetic material in a single cell nucleus can breed a
chicken which will lay eggs full of the right proteins.

One of the genetically-modified chickens, named Britney, will be unveiled by
the Roslin Institute, which cloned Dolly, at Edinburgh Castle on Wednesday.

Each chicken should lay about 250 eggs per year producing huge quantities
of the necessary proteins.

Until now, producing even small quantities of usable proteins in the laboratory
has proved difficult and expensive. This has hampered the development of
new drugs to treat various illnesses including ovarian cancer and breast
cancer.

But each egg from Britney and the rest of the flock will contain 100mg or
more of the proteins which can be easily extracted.

Britney was developed over two years by US biotech company Viragen and
the Roslin Institute in Edinburgh.
