Cats' eye diseases genetically linked to diseases in humans

COLUMBIA, Mo. About one in 3,500 people are affected with retinitis pigmentosa (RP), a disease of the retina's visual cells that eventually leads to blindness. Now, a University of Missouri researcher has identified a genetic link between cats and humans for two different forms of RP. This discov...

Scientists unlock possible aging secret in genetically altered fruit fly

Researchers genetically link Lou Gehrig's disease in humans to dog disease

COLUMBIA, Mo. An incurable, paralyzing disease in humans is now genetically linked to a similar disease in dogs. Researchers from the University of Missouri and the Broad Institute have found that the genetic mutation responsible for degenerative myelopathy (DM) in dogs is the same mutation that c...

Novel bioreactor enhances interleukin-12 production in genetically modified tobacco plants

WORCESTER, Mass. Dec. 3, 2008 Interleukin-12 is a naturally occurring protein essential for the proper functioning of the human immune system.

Scientists genetically engineer tomatoes with enhanced folate content

Leafy greens and beans aren't the only foods that pack a punch of folate, the vitamin essential for a healthy start to pregnancy. Researchers now have used genetic engineering--manipulating an organism's genes--to make tomatoes with a full day's worth of the nutrient in a single serving. The scie...

Researchers create genetically matched embryonic stem cells for transplantation

Researchers at Children's Hospital Boston report a new and efficient strategy, using eggs alone, for creating mouse embryonic stem cells that can be transplanted without the risk of rejection because the cells are compatible with the recipient's immune system. The findings will be published online ...

Researchers report technique for freezing and preserving genetically enhanced pig embryos

Researchers led by a University of Missouri-Columbia professor of reproductive biotechnology have reported success in freezing and preserving swine embryos that were created by in vitro techniques and that carried modified genetic material. After thawing and transfer to a surrogate mother, some of ...

How can identical twins be genetically different?

They sleep together, eat together, and most people find it impossible to tell them apart. Identical twins who grow up together share just about everything, including their genes. But sometimes only one twin will have health problems when genetics predicts both of them should. Scientists at the U...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

What makes dancers different than the rest of us? Genetic variants, says a researcher at the Hebrew University of Jerusalem. In a study published in the American journal, Public Library of Science Genetics, Psychology Prof. Richard P. Ebstein and his research associates have shown, through DNA...

Understanding how weeds are resistant to herbicides

...you have these genetic fingerprinting tools, which we're able to do because of this research, you can go look at these populations and see, are these genetically similar, which would suggest that it was a movement event. If they're completely different, then that would suggest that it's evolving independently."...
