By inserting a version of GFP along with their gene of choice, they could easily see if they were successful because the organism would glow. It seems like once the scientists figured out how to make glow-in-the-dark animals, they wasted no time in making everything within reach into a Halloween decoration. I think the point I really wanted to make is that it doesn't always have to be that way. Nevertheless, there are other criticisms of the use of GM animals, as the watchdog group GeneWatch has pointed out. CNN explored these examples and some of the stickier ethical questions posed by engineering animals in an interview this week with Anthes. Continue I would hate to see these technologies rejected out of hand when there may be some useful applications. A cyborg beetle or a pet fish engineered to glow under ultraviolet light might sound like something you'd see in a movie about the future. Even outside of any ethical considerations, the alteration of a natural evolutionary cycle of an animal could have consequences we’ve not even considered. Pros and Cons of GMO. The substance that makes the cat glow is a version of the green fluorescent protein that lights up the crystal jelly, a type of jellyfish that lives off the West Coast of the United States. You have a lot of those factors wrapped together when you talk about something like genetic engineering. I like animals, and I don't want to see us creating rats that are just studded with tumors all the time, but if you told me that would actually yield a cure for cancer, it's hard to say no to that. Advertising Notice The ultimate goal of this line of research, though, is to figure out how to make humans resistant to HIV, the virus that causes human AIDS. Not every product will be harmful and dangerous, and some might actually be beneficial. And who are we to be, quote-unquote, playing God? These mutants are then used to test drugs that could counter these ailments in humans. Cloning, for example, falls into this discussion, as does "pharming," or genetically engineering animals for medicinal purposes. "These males produce offspring that do not develop fully. Vote Now! Advancements in prosthetics are giving new options to injured animals -- and occasionally benefiting humans, too. "Our scientific tools are new, but the ethical questions they raise are not," she says. In this latest bit of research, published in Nature Methods, the Mayo Clinic scientists inserted a version of the GFP gene along with a gene from the rhesus macaque that blocks the feline immunodeficiency virus (FIV)—the virus that causes feline AIDS—into the unfertilized eggs of a cat. As mentioned before, fluorescent Glofish purpose is to protect the environment from the pollution, this transgenic fish could determine when a waterway is contaminated by fluorescent, therefore if the fish is not fluorescent then the water is not contaminated. Its director Helen Wallace says the rise in the use of GM animals reveals a disturbing trend: the "genetification" of biology. "Too much food and exposure to pollutants are also clear causes of cancer and obesity, but these are being ignored because of our obsession with genetics. That the protection gene is expressed in the cat lymphoid organs, where AIDS virus spread and cell death mostly play out, is encouraging to us, however.”. These are all questions that come up again and again. Thus it may be possible one day to cook omelettes that could prevent us succumbing to disease, though most scientists envisage a slightly different route in which GM egg whites are dried out before their antibodies are removed and administered separately. Sometimes we want to change them just to look nice to us. With cats, for instance, there's one gene in particular that codes for a protein that is what a lot of humans react to. At the root of it is the fact that this is new and high-tech. Get the best of Smithsonian magazine by email. "We have created a strain of genetically modified male mosquitoes of the Aedes aegypti species, the one responsible for spreading dengue fever," he says. ", As Home Office statistics reveal a 10% rise in the use of genetically modified animals for research, scientists appear to be divided about their usefulness, The genetically modified piglet glows in the dark as the result of jellyfish genes introduced into its cells at the University of Missouri. "You can take a sample of cells from a green embryo and then put them into a normal embryo," says Sang. “We haven’t shown cats that are AIDS-proof,” study co-author Eric Poeschla told LiveScience. ", Alphey and his colleagues are working on techniques to prevent mosquitoes from spreading dengue fever, a severe, sometimes fatal viral illness that affects between 50 to 100 million people a year. For now at least, these cats are simply valuable research animals that might one day contribute to a greater understanding of certain illnesses and that understanding might lead to cures for cancer, diabetes and more I don't like the idea of testing cosmetics on animals, and I think a lot of people would agree with me. After those eggs were fertilized, they produced kitties that glowed green, showing that they also had the anti-FIV gene. Why? As Home Office statistics reveal a 10% rise in the use of genetically modified animals for … or and then, 'If it's unnatural, does that make it wrong?' List of the Pros of Transgenic Animals. Released into the wild, which we hope to do in a few years, these GM mosquitoes should eradicate A. aegypti populations and halt new dengue fever cases. But when the lights are out, the cat glows under an ultraviolet light thanks to a fluorescence gene in his cells. “We still have to do infection studies involving whole cats. "Frankenstein's Cat" author Emily Anthes with her dog, Milo. ", This point is acknowledged – partially – by genetic engineers. "There are undoubtedly some legitimate uses of GM animals but this blanket rise is worrying and bears little relation to reality," she says. Those are just two of the developments science journalist. But if that's the case, then the future is here. Of course, that's not any consolation for the animal. By contrast, a mammal foetus gestates inside the uterus of its mother, making it far harder for researchers to monitor physiological changes. So they block the appearance of new A. aegypti mosquitoes. That's probably one of the most -- if not the most -- common uses of genetic engineering, is scientists engineering rats and mice who suffer from various diseases that they then want to study to learn about cures or treatments for human disease. I think a genetically engineered hypoallergenic cat is something that there would be a lot of demand for, and something I could very easily envision being a hit on the marketplace. It's tricky, because it seems deeply unfair, and in some senses, it is. Are we sort of unleashing forces that we can't control? Sarah Zielinski is an award-winning science writer and editor. So the more we learn about genetic influences the more we will know about their environmental influences as well. “We want to see if we can protect the domestic cat against its AIDS virus, if we can protect any species, eventually including ours, against its own AIDS virus,” Poeschla told LiveScience. At the same time, there was a corresponding decrease in experiments on "natural" animals. The researchers still have more work to do to determine whether the anti-FIV gene works in the cats. And there will certainly be cases in which we want to make alterations that are not good for animals, are not good for humans, are not good for the environment, and we should absolutely reject those products. In other words, more and more scientists are now relying on the use of GM animals, as opposed to unmodified ones, for their research. That's a phrase you see all the time in the animal world. In other words, stem-cell science can get a boost from the glowing green chicken. As we have noted, the technique involves putting jellyfish genes into the DNA of a chick so that it makes a green, fluorescent protein.

Biotech's capabilities extend to pet owners. Cookie Policy Cat owners might find a glow-in-the-dark kitty to be fairly useful—you’ll never trip over the cat at night again—but the Mayo Clinic scientists who created this glowing cat had a bigger goal in mind: fighting AIDS. After all, who needs poultry that can shine a light on itself? If the idea of owning a cat that glows in the dark appeals to you, don't get your hopes up any time soon. Frankenstein's Cat: Cuddling up to Biotech's Brave New Beasts, Science journalist Emily Anthes explores biotech's innovations in a new book, She covers topics such as cloning and genetic engineering, Though the tools are new, Anthes says, the ethical questions are not. We don't want to see them suffer, and yet if their suffering gives us a cure for cancer, then maybe that's OK. "You can then watch and see what organ that group of cells develops into because that tissue will have a green fluorescence.
