- Affymetrix 500K array used to identify memory gene
10-19-2006 · EurekAlert!
Affymetrix Inc., announced today that researchers at the Translational Genomics Research Institute in Phoenix, Ariz., have used the Affymetrix 500K Array to discover a gene -- called Kibra -- associated with memory performance in humans. The team's findings may be used to develop new medicines for memory-based diseases such as Alzheimer's and Parkinson's by providing scientists with a better understanding of how memory works at the molecular level.

- Research team identifies human 'memory gene'
10-19-2006 · EurekAlert!
Researchers at the Translational Genomics Research Institute (TGen) today announced the discovery of a gene that plays a significant role in memory performance in humans. The study details how researchers associated memory performance with a gene called Kibra in over 1,000 individuals -- both young and old -- from Switzerland and Arizona. This study is the first to describe scanning the human genetic blueprint at over 500,000 positions to identify cognitive differences between humans.

- Individual differences in a clock gene predict decline of performance during sleep deprivation
03-08-2007 · EurekAlert!
People are known to differ markedly in their response to sleep deprivation, but the biological underpinnings of these differences have remained difficult to identify. Researchers have now found that a genetic difference in a so-called clock gene, PERIOD3, makes some people particularly sensitive to the effects of sleep deprivation.

- Taking 'chips' to the next level of gene hunting
11-14-2006 · EurekAlert!
Researchers at the Johns Hopkins' High Throughput Biology Center have invented two new gene "chip" technologies that can be used to help identify otherwise elusive disease-causing mutations in the 97 percent of the genome long believed to be "junk."

- Researchers first to map gene that regulates adult stem cell growth
01-14-2007 · EurekAlert!
A new discovery in stem cell research may mean big things for cancer patients in the future. After being the first to genetically map and identify a gene that regulates adult stem cells, the researchers investigated the gene's protein product, Latexin, which can be used to ramp up the body's stem cell count. The team's findings are being published in Nature Genetics.

- Autism gene identified by researchers at Yale working with a global research consortium
03-13-2007 · EurekAlert!
Yale School of Medicine autism experts Fred Volkmar, M.D. and Ami Klin are part of a global research consortium from 19 countries to identify a gene and a region of a chromosome that may lead to autism in children.The findings are published online today in Nature Genetics and also will be published in the journal's March print edition.

- Under magnetic force, nanoparticles may deliver gene therapy
07-31-2007 · EurekAlert!
After binding DNA segments to tiny iron-containing spheres called nanoparticles, researchers have used magnetic fields to direct the nanoparticles into arterial muscle cells, where the DNA could have a therapeutic effect. Although the research, done in cell cultures, is in early stages, it may represent a new method for delivering gene therapy to benefit blood vessels damaged by arterial disease.

- Enzyme regulates brain pathology induced by cocaine, stress
11-07-2007 · EurekAlert!
Researchers have uncovered a key genetic switch that chronic cocaine or stress influences to cause the brain to descend into a pathological state. In studies with mice they showed how chronic cocaine changes gene activity to enhance the addictive reward from the drug. And they showed similarly how chronic stress induces the same kinds of changes that hypersensitizes the brain, causing depression-like symptoms.
