The genetic basis of inbreeding avoidance in house mice
11-08-2007 · EurekAlert!A new study appearing online on Nov. 8 in Current Biology, a publication of Cell Press, offers new insight into how wild house mice avoid mating with their relatives. The mice rely on a diverse set of specially evolved proteins in their urine, called major urinary proteins, to identify relatives and avoid mating with them.

- Genetic hearing loss may be reversible without gene therapy
02-22-2007 · EurekAlert!
A large proportion of genetically caused deafness in humans may be reversible by compensating for a missing protein. Researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30. The findings come 10 years after scientists first discovered that connexin26 mutations cause much of the deafness diagnosed at birth.

- Genetic 'roadblock' hoped to inspire future type 2 diabetes research
10-02-2007 · EurekAlert!
A team of Mount Sinai Hospital researchers has found that a 'genetic roadblock' identified in a recent study could pave the way toward novel treatments for type 2 diabetes. In the study, researchers from the Samuel Lunenfeld Research Institute of Mount Sinai Hospital found the first genetic evidence that the elimination of the gene for glycogen synthase kinase-3 in mice sensitizes the animals to insulin.

- Regulatory pathway in brain development possible basis for malformations
12-04-2006 · EurekAlert!
Researchers at UCSD School of Medicine have identified a genetic regulator of brain development that sheds new light on how immature neural cells choose between proliferation and differentiation. Defects in regulating this choice result in brain malformations. Their research will be published on line the week of December 4, in advance of publication in the Proceedings of the National Academy of Sciences (PNAS).

- UCSB study on sibling detection mechanism highlighted in Nature
02-15-2007 · EurekAlert!
A team of researchers at the University of California, Santa Barbara, has found evidence of a nonconscious mechanism in the human brain that identifies genetic siblings on the basis of cues that guided our hunter-gatherer ancestors. Their findings will be published in the Feb. 15 issue of the science journal Nature.

- Blind mice shed light on human sight loss
11-21-2007 · EurekAlert!
Mutant mice could provide genetic clues to understanding incurable human sight loss resulting from retinal degeneration. Research published in the online open access journal Genome Biology uncovers a role for microRNA in retinal disease, and may point the way to future therapies.

- Origin of inherited pain disorder pinpointed
12-06-2006 · EurekAlert!
The genetic basis for a rare inherited disorder that causes severe burning pain with no warning has been pinpointed by researchers. They found that paroxysmal extreme pain disorder (PEPD) is caused by specific mutations in porelike sodium channels in peripheral nerve cells -- a discovery that they said emphasizes the role of such channel disorders in inflammatory pain. Such findings of abnormal function in disease also provide insights into the normal function of such channels, they said.

- Biological markers of prostate cancer shed light on cancer burden faced by African-American men
11-29-2007 · EurekAlert!
Researchers based at Tulane University report the discovery of biological markers of prostate cancer which are involved in the growth of tumor cells, shedding light on the genetic basis for the prostate cancer burden faced by African-American men. The research is being presented today at the American Association for Cancer Research conference on The Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, being held Nov. 27-30.
