The alpha-gal-free pig has one express purpose for now: to develop medical products, like blood thinners, that won't set off adverse reactions. United Therapeutics Corp. has a proprietary process for snipping the DNA, but an industry observer says it likely works by removing the gene that makes alpha-gal and stanching that space with a “blank” genetic placeholder instead, AP reports.
For humans with similar and devastating food allergies, a new pig with a vanquished allergen could mean better options and easier decisions. This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.
Under current rules, the genetically enhanced animals would be allowed to compete at all international events, including the Olympics. By editing this tag, scientists are able to target specific regions of DNA and make precise cuts, wherever they like.
Experts from Sharon Biotech, a specialist equine cloning facility based in Buenos Aires, have focused on the misstating gene sequence which controls and limits the growth of muscles. The process has already created healthy embryos, and they are expected to be implanted into surrogate mothers within two years.
'Additionally, as progeny of cloned horses will be produced by conventional reproductive methods, such as natural covering or artificial insemination, maintaining fair play is protected. Cloning however, does not improve the lineage of a horse and 'improve' it in any way, it simply produces a genetically identical copy of the original.
This new development would allow breeders and trainers to 'customize' the DNA of their horses in order to produce an animal with the most desirable traits. Currently, there are no rules in place to stop genetically modified animals from competing in any international competitions, including the Olympics.
The animals would be stronger, faster and able to jump higher, scientists hope Credit: Sharon Biotech FollowGenetically engineered horses designed to be faster, stronger and better jumpers will be born in 2019 after a breakthrough by the same laboratory which clones polo ponies.
Scientists in Argentina successfully used a powerful DNA editing technique called CRISPR to rewrite the genomes of cloned horses. The team focussed on boosting the misstating gene sequence which is crucial to muscle development, endurance and speed.
Last year, Adolfo Cambial rode six horses cloned from the same mare, to help his team win the Argentinian open. “Additionally, as progeny of cloned horses will be produced by conventional reproductive methods, such as natural covering or artificial insemination, maintaining fair play is protected.
Warm blood fragile foal syndrome is a severe, usually fatal, genetic disease that manifests itself after birth in affected horses. Under force, for instance, the skin tears from the tissue underneath and the joints can suffer dislocation.
A research team from the Universities of Göttingen and Halle has now been able to prove that the disease did not stem from the English thoroughbred stallion Dark Ronald XX, which had been the assumption until now. It is called PLOD1 and normally ensures that collagen molecules in the skin and connective tissue can bind to form a stable network.
Since the spread of the genetic defect is also a problem in horse-breeding in Germany, the Veracity Informationssysteme Tierhaltung (IT-Solutions for Animal Production) in Verde 2019 determined the possible origin of the genetic defect from the test results of around 2,000 horses and their pedigree records. “We have now succeeded in proving that Dark Ronald XX was not a carrier of the PLOD1 mutation and can therefore be excluded as the original source of this genetic defect,” says Professor Bertram Being, Director of the Institute of Veterinary Medicine at the University of Göttingen and lead author of the study.
Doubts about whether the mutation descended from Dark Ronald XX were already expressed in 2019, and further investigation reveals a Hanoverian stallion born in 1861. Dark Ronald XX was an important thoroughbred stallion who had a great influence on German horse-breeding.
He was sold to Germany in 1913 and was used as a stud -- a stallion with highly prized heritable characteristics -- first in Granite and later in Altered. In 1928, he was brought to the veterinary clinic of the University of Halle for treatment due to intestinal colic and this is where he died.
Since then his remains -- such as skeleton, heart and skin -- have been kept in one of the natural science collections of the Martin Luther University Halle-Wittenberg. “This is most fortunate, as it has allowed us to examine Dark Ronald XX directly for the presence of the PLOD1 mutation,” says Being.

The mosquito is also approved to be released into Harris County, Texas, beginning in 2021, according to Oxide, the US-owned, British-based company that developed the genetically modified organism (GMO). “This is an exciting development because it represents the ground-breaking work of hundreds of passionate people over more than a decade in multiple countries, all of whom want to protect communities from dengue, Zika, yellow fever, and other vector-borne diseases,” Oxide CEO Grey Grandson said in a statement.
In 2009 and 2010, local outbreaks of dengue fever, which is spread by the Andes Egypt, left the Florida Keys Mosquito Control District desperate for new options. The company had developed a male mosquito named OX513A, programmed to die before adulthood unless it was grown in water that contained the antibiotic tetracycline.
OX513A had been field tested in the Cayman Islands, Panama and Brazil, with Oxide reporting a large success rate with each release. But when word spread in the Florida Keys that the mosquito was on the way, public backlash was swift: More than 100,000 people signed a Change.org petition against the proposal; that number has grown to more than 242,000 today.
The EPA spent years investigating the mosquito's impact on both human health and the environment, allowing time for public input. However, environmental groups worry that the spread of the genetically modified male genes into the wild population could potentially harm threatened and endangered species of birds, insects and mammals that feed on the mosquitoes.
Once again, the Trump administration is callously disregarding scientific experts and the will of communities to force this risky experiment through,” said Dana Perls, program manager for the food and technology campaign of Friends of the Earth, in a statement. Approved by the Environment Protection Agency this week, the pilot project is designed to test if the genetically modified mosquito is a viable alternative to spraying insecticides to control the Andes Egypt.
