* D$ V% }1 ^2 }A glowing bunny sounds like a creature from Jefferson Airplane’s psychedelic-laced song, “White Rabbit,” but real fluorescent rabbits were recently born at the University of Istanbul, Turkey. F D [% O3 |. B公仔箱論壇Rabbits join a growing list of fluorescent fur-bearers. Genetic engineers have created glowing dogs, cats, pigs and mice by inserting a gene from a jellyfish into the mammals’ DNA. The jellyfish gene codes for a protein that emits light when exposed to ultraviolet light. ; t' g6 ]2 G. U6 y( P7 W! ~The jellyfish gene adds an obvious physical change to an engineered animal. This allows scientists to know that genetic material successfully transferred into a new organism. & @: ^' O; R) Y$ T公仔箱論壇For example, when Mayo Clinic researchers genetically engineered cats to carry a protein that defends the animals from infection by the feline immunodeficiency virus (FIV, the cat version of HIV), the scientists added the fluorescent gene along with the FIV-resistance gene. That way they knew that any cat that fluoresced also carried protein protection against FIV, a trait that would otherwise be invisible.公仔箱論壇5 @3 Q% Q1 _9 r$ M# a, s8 F% X
