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.”
