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., W: K. j8 b9 ?( a2 ^8 g
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.* p1 b- u! G, ]5 r
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. + F5 {$ j: y! }/ `; B8 l* x8 ]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.os.tvboxnow.com* h. p3 a3 k) o1 Q, o& S B
