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. 5 g- r1 W' X0 M# c9 c3 Ywww2.tvboxnow.comRabbits 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. . K$ C3 I& { |6 owww2.tvboxnow.comThe 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. 8 ?5 J1 W( h$ C0 |3 \! aFor 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./ X9 M9 {1 r5 F- W. f
