These cells were grown in an incubator in media containing the gene for AT III. Cloning is desirable because it would increase the efficiency rate. “It falls right into people’s worst assumptions about how this technology can be used,” Van Eenennaam says. Copyright © 2005 - 2020 Royan Institute. ... Hanna, the first cloned goat was born. Our transgenic goats are very strictly regulated. "The technology used to clone the three Genzyme goats is one of the first applications of the nuclear transfer (cloning) procedure to produce transgenic goats for the pharmaceutical industry, said Richard Denniston, a researcher with the LSU Agricultural Center. The resulting cloned embryo is then transferred into a recipient female that carries the clone to term.". "That’s what really made big news, taking a cell from an adult animal," he said. The spider silk proteins then have to be purified (link this to Heather Rothfuss write-up once completed) from the other milk proteins, a process that is challenging! They asked us to, and we did," he said. Four different molecular building blocks of the DNA material are put in a vial, and a gene is built synthetically. If a female is produced, she will produce milk with the AT III protein, which can be extracted from the milk for pharmaceutical use. The first transgenic mouse was created in 1985, followed a few years later by genetically modified rabbits, pigs, sheep, and cattle. The protein, anti-thrombin III (AT III), is now in the third phase of human clinical trials. Bonyana and Tamina were also first cloned calves produced in Royan Institute in 2009 and were died due to an infectious disease in a couple of days. Transgenic Goats. While much of the research was done at LSU in Baton Rouge, the goats made their appearance last fall at the Genzyme farm in Massachusetts. LSU researchers have for the past six years carried a collaborative research program with Genzyme, which may become the first company to have a transgenic product on the market. A third source is a developing fetus. "Genzyme takes the gene for anti-thrombin III. Royan TGF91 and Royan TGF92, the two transgenic goats were also named "Shangoul" and "Mangoul", names of the … They get a 30-day fetus, culture fiborblast cells, insert the gene for AT III into fiborblast cells, do nuclear transfer, send embryos to us, and we transfer them into recipients.". Though she’s a million-dollar goat, she doesn’t look any different from the other goats she hangs out with. The transgenic goat clones born from the joint LSU/Genzyme project were produced by taking fibroblast cells from a 30-day female goat fetus. The reason is that very little is known about the safety of transgenic animals. The main purpose of producing transgenic animals is to produce animals that contain the gene for secretion of some proteins in their milk which can be used in treatment of human diseases. Then you can make millions of copies of that," he explained. During the first cell divisions, the gene may become attached to the genetic material of the embryo. An article in the May issue of Nature Biotechnology will announce the breakthrough. The agricultural applications of this technique are widespread. All Rights Reserved. Researchers at Tufts University School of Veterinary Medicine also participated in the research. She is different, though, because her milk contains a therapeutic protein that could be extracted to make a drug for patients undergoing coronary bypass surgery. During a news conference on Saturday, Jan. 30th, Hamid Gourabi, the head of Royan Institute said: Following 3 years of research on transgenic animals, the institute has succeeded in producing of two transgenic goats containing coagulation factor IX in their milk which is an important drug using in treatment of hemophilia patients. Em- The drug works in conjunction with heparin, which prevents blood from clotting. Iran's First Transgenic Goats Produced in Royan Institute. Not all pregnancies are successful, but 100 percent of the births will be females with the gene for AT III," Denniston said. Now you’ve got an animal that is very valuable. How do you produce these animals as quickly as possible? Using the cloning process in conjunction with transgenics improves the overall efficiency of producing transgenic animals, Denniston said. LSU’s contract with Genzyme has brought LSU approximately $850,000 in research funds, and LSU’s reproductive physiology laboratory will continue working with the nuclear transfer process as a tool for pharmaceuticals, agricultural applications and propagation of endangered species. When you insert the AT III protein into 1,000 fertilized eggs and transfer 100 embryos, you can expect one transgenic offspring. These cloned embryos were then transferred into a recipient goat. "The market for AT III is $200 million. Production of transgenic founder goats involves introducing and stably integrating an engineered piece of DNA into the genome of the animal. "The Massachusetts farm has more than 1,500 goats under the watchful eye of the FDA. Before using our website, please read our Privacy Policy. They produce the gene in a lab in Framingham. Transgenics is the process of taking DNA from one species and implanting it into the genetic structure of another. Customized by, Cell Journal(Yakhteh) and International Journal of Fertility and Sterility, Current Issues, The Current Issue of Cell Journal(Yakhteh), The Current Issue of International Journal of Fertility and Sterility (IJFS), Professor Hossein Baharvand Laureates 2019 Mustafa Prize, Endocrinology and Female Infertility Clinic, Ethical Codes for Medical Research on Human in Iran. Genzyme has received a patent on the protein. Genzyme does the molecular work. Transgenic animals have numerous applications in agriculture, medicine, and industry. Once researchers identify the code, they can punch it into a DNA sequencer. They have largely now been brought to the United States (thanks to an exemption by the USDA). Even with the cost being a half to $1 millon per animal, the potential earnings from the pharmaceutical product are enormous," the LSU researcher said. These goats express one of two spider silk proteins in their milk; Major ampullate silk protein 1 (MaSp1) or major ampullate silk protein 2 (MaSp2).
