Glowing dogs a medical breakthrough?

Seoul, SOUTH KOREA The four dogs, all named "Ruppy", a combination of "ruby" and "puppy", look like normal beagles in daylight. But, under ultraviolet light, their nails and abdomens have a red glow.

The research team from /*Seoul National University*/ called the dogs the first transgenic dogs carrying fluorescent genes.

Scientists took skin cells from a beagle, inserted fluorescent genes into the cells and eggs that were implanted into a mixed-breed dog.

Six female beagles were born in December 2007, only four survived.

Researchers say the process could help find new treatments for genetic diseases such as /*Parkinson's*/ disease.

A South Korean scientist created glowing cats two years ago based on similar cloning techniques.
