South Korean Experts Claim to Have Cloned Glowing Dogs
Glowing dogs: SKorean scientists say cloned beagles turn red under UV rays

By HYUNG-JIN KIM Associated Press Writer

SEOUL, South Korea

South Korean scientists say they have engineered four beagles that glow red using cloning techniques that could help develop cures for human diseases. The four dogs, all named "Ruppy" — a combination of the words "ruby" and "puppy" — look like typical beagles by daylight.

But they glow red under ultraviolet light, and the dogs' nails and abdomens, which have thin skins, look red even to the naked eye.

Seoul National University professor Lee Byeong-chun, head of the research team, called them the world's first transgenic dogs carrying fluorescent genes, an achievement that goes beyond just the glowing novelty.

"What's significant in this work is not the dogs expressing red colors but that we planted genes into them," Lee told The Associated Press on Tuesday.

His team identified the dogs as clones of a cell donor through DNA tests and earlier this month introduced the achievement in a paper on the Web site of the journal "Genesis."

Scientists in the U.S., Japan and in Europe previously have cloned fluorescent mice and pigs, but this would be the first time dogs with modified genes have been cloned successfully, Lee said.

He said his team took skin cells from a beagle, inserted fluorescent genes into them and put them into eggs before implanted them into the womb of a surrogate mother, a local mixed breed.

Six female beagles were born in December 2007 through a cloning with a gene that produces a red fluorescent protein that make them glow, he said. Two died, but the four others survived.

The glowing dogs show that it is possible to successfully insert genes with a specific trait, which could lead to implanting other, non-fluorescent genes that could help treat specific diseases, Lee said.

The scientist said his team has started to implant human disease-related genes in the course of dog cloning, saying that will help them find new treatments for genetic diseases such as Parkinson's. He refused to provide further details, saying the research was still under way.

A South Korean scientist who created glowing cats in 2007 based on a similar cloning technique said that Lee's puppies are genuine clones, saying he had seen them and had read about them in the journal.

"We can appraise this is a step forward" toward finding cures for human diseases, said veterinary professor Kong Il-keun at South Korea's Gyeongsang National University. "What is important now is on what specific diseases (Lee's team) will focus on."

Lee was a key aide to disgraced scientist Hwang Woo-suk, whose breakthroughs on stem cell research were found to have been made using faked data. Independent tests, however, later proved the team's dog cloning was genuine.

I think this is outrageous.

Yeah.. also started a thread a week ago, and i got redirected to a thread which is like half month old.

Sometimes news come in too late.

I'm glad it was reposted because I have never seen any of the other ones.

The guy says it proves helpful for other diseases, then why doesn't he just work on those and stop messing around with useless crap like a glow in the dark pooch?

The glowing is used as a marker to indicate that their desired gene is there. Whithout that they may not know if the subject has the disease, corrected genes, or whatever else they're attempting to merge into the animal. Just because you don't understand it doesn't mean it's just useless crap.

Forget what I was about to say....I'm not in the mood for an argument. As for you...assuming things isn't a good practice. I never said I didn't understand what it was for. Yes, it's crap.

I know I'm in the minority here, but I think this is a good thing. This will prove to be very useful in identifying genes that cause certain diseases. And with all the publicity these pups are getting, I'm sure they're being treated very well.
