B
SEOUL: South Korean scientists have cloned cats that glow red
in the dark, an achievement that could help develop cures for human genetic
diseases, the Science and Technology Ministry said.
Three Turkish
angora cats were born in January and February through cloning with a gene that
produces a red florescent (荧光的) protein that makes them
glow in the dark. One died at birth, but the two others survived, the ministry
said.
The ministry
claimed it was the first time cats with modified genes had been cloned.
Scientists from Gyeongsang National
University took skin
cells from a cat and inserted the florescent gene into them before
transplanting the genetically modified cells into eggs.
The development
means other genes can also be inserted in the course of cloning, leading to a
way to produce lab cats with genetic diseases, including those of humans, to
help develop new treatments, the ministry said.
“Cats have
similar genes to those of humans,” veterinary professor Kong Ⅱ-keun of Gyeongsang National
University said.
“We can make
genetically modified cats that can be used to develop new cures for genetic
diseases.”
Keitaro Kato, a geneticist at Kinki
University in western Japan
who has cloned fish, said the research could be significant if it eventually
helps treat people with genetic diseases.
“People with
genetic disorders usually have to receive treatment throughout their lives that
is very hard on them,” Kato said.
“If these results
can help to make their lives easier, then I think it’s a wonderful thing.”
