Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...rding to new research in mice conducted by medical geneticists at Duke University Medical Center. Infants born with the inherited muscular disorder called Pompe disease usually die before they reach the age of two. The researchers also said their approach of targeting corrective genes to muscles may have applica...

Critical role in programmed cell death identified

Dartmouth Medical School geneticists have found links in the cell death machinery of worms and mammals, opening new avenues for studying and targeting a process vital to development and implicated in cancer and autoimmune diseases. The work, reported in the February 17 issue of Nature,...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

... said that techniques now being developed by plant geneticists -- such as modifying chloroplast DNA rather than nuclear DNA -- will eventually reduce the need for such constant monitoring. Since chloroplast DNA is maternally inherited, there is little risk of pollen transfer, said Terry. Terry said it's worth p...

Insight into DNA's 'weakest links' may yield clues to cancer biology

...ions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them. The findings, published in the March 11, 2005, issue of C...

Maine Researchers Find Exceptions to Old Rules of Genetic Inheritance

...ng majority of males are sterile. Until now, most geneticists suspected that both transmission ratio distortion and sterility were due to the same mutations in a small number of genes residing in the t haplotype. The hypothesis was logical since the phenomena of transmission ratio distortion and sterility alway...

15-year hunt finds cause of pseudothalidomide syndrome

... time." A few years later, in 1995, two Colombian geneticists started their quest to fully understand Roberts syndrome. Without their push, the gene for Roberts might still be unknown. Colombian Hugo Vega had noticed an unusual number of patients with Roberts syndrome in the clinic at the University of Bogotá....

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scienti...ribe MADM as "an elegant method" that brings mouse geneticists "one step closer to the enviable experimental facility available to invertebrate geneticists." Ther...

New technique could alter field of mouse genetics

...ks," Xu said, "but this system is a dream tool for geneticists working with vertebrates and mammals." PiggyBac inserts randomly into the genome, with a clear preference for genes. This bodes well for its use in mutating genes and for identifying unrecognized genes in places of the genome that have been especial...

New technique multiplies life span in simple organisms

Same-sex mating by fungi spawned infection outbreak, evidence suggests

... British Columbia, Howard Hughes Medical Institute geneticists at Duke University Medical Center have reported. The fungus, Cryptococcus gattii, is normally restricted to the tropics and subtropics. The researchers said their findings provide important additional insight into the origin of the Vancouver Island ...

Gene increases risk of tuberculosis

...the scene. In an accompanying commentary article, geneticists Alexandre Alcais, Jean-Laurent Casanova and their colleagues at the University of Paris note that this is the largest genetic impact on adult TB that has ever been described. ...

MIT: Oceans are a major gene swap-meet for plankton

... swapped in and swapped out, known among molecular geneticists as "hot spots" for gene exchange. The distributors or carriers of new genes, they suspect, are the massive numbers of viruses also known to exist in seawater, some of which are adept at infecting ocean microbes such as Prochlorococcus. Such viruses,...

Ancient DNA provides clues to the evolution of social behavior

...nt and modern DNA with population models will help geneticists understand the role population size and structure play in the maintenance of genetic diversity. ''I think eventually this will feed back into modifying our understanding of population genetic theory and how sensitive it is to real-life events,'' Had...

HortResearch science reveals the natural potential of apples

... Speaking at a gathering of the world's top fruit geneticists in Hawke's Bay, New Zealand, HortResearch Chief Scientist Dr Ian Ferguson said the technology held the capacity to revolutionise the apple industry. "By understanding fruit at a genetic level we are able to unlock the true potential of nature and pr...

Researchers discover a new genetic cause of Alzheimer's disease

...might also play a role in Alzheimer's disease. The geneticists from Antwerp systematically studied the hereditary code that is responsible for controlling the expression of the gene (= promoter). Biological processes in our body are strictly regulated, primarily by closely controlling the amount of each protein ...

Paleontologists learn how not to become a fossil

...r kin), because they serve paleontologists the way geneticists use mice or fruit flies as model systems. Jablonski called the clam "a real bellweather" for understanding many long-term changes in biodiversity. Said Kidwell: "This group is hughly important out there in the modern seas, constituting a big fractio...

Study finds 60 new genes controlled by DNA snippet

...y functional regulatory elements as we can to help geneticists pinpoint a growing number of disease-causing mutations." Study Details In Miano's study, the regulatory sequence under examination was the CArG box. The nucleotide building blocks of DNA chains may contain any one of four nucleobases: adenine (A),...

Novel connection found between biological clock and cancer

Dartmouth Medical School geneticists have discovered that DNA damage resets the cellular circadian clock, suggesting links among circadian timing, the cycle of cell division, and the propensity for cancer. Their work, reported June 29 in Science Express, the advance electronic publicat...
