Wheat can fatally starve insect predators
01-10-2007 · EurekAlert!
A newly identified wheat gene produces proteins that appear to attack the stomach lining of a crop-destroying fly larvae so that the bugs starve to death. The gene's role in creating resistance to Hessian flies was a surprise to U.S. Department of Agriculture and Purdue University researchers, discoverers of the gene and its function.

Severe form of 'enlarged prostate' disease discovered
02-05-2007 · EurekAlert!
Millions of middle-aged and older men experience the symptoms of an enlarged prostate multiple times during the day and night. What they may not know is that the disease known as BPH (benign prostatic hyperplasia), marked by urgency and frequent urination, is not one but at least a pair of disorders, and that one of the pair -- tied to a newly identified gene -- has far more serious implications.

Genetic mutation explains form of brittle bone disease
10-19-2006 · EurekAlert!
A newly identified gene mutation helps explain a subset of cases of osteogenesis imperfecta, or brittle bone disease, whose origin had until now remained mysterious. Identifying the new mutation is important because children with the disorder, whose bones break easily, are sometimes mistaken as victims of child abuse -- particularly those who do not carry the genetic mutation known to cause most cases of brittle bone disease.

Newly identified mechanism for silencing genes points to possible anti-cancer strategies
05-16-2007 · EurekAlert!
Scientists are only beginning to appreciate the extraordinary degree of control exercised over every step of the gene-to-protein production process. Only about 10 percent of human genes, for example, are active in a given cell at a given time, with the remaining 90 percent silenced by a various mechanisms. In a just-published study in Nature, scientists report an important new gene-silencing mechanism that points to promising potential targets for anti-cancer interventions.

New gene may offer clues to infertility in both cows and women
10-29-2007 · EurekAlert!
A newly identified gene that controls embryo development in cows may someday offer clues into the cause of infertility in women. A team of researchers from Michigan State University led by George Smith, associate professor of animal science, has discovered that the new egg-specific gene, JY-1, is necessary for embryonic development in dairy cows. The research is reported in the Oct. 29 online issue of the Proceedings of the National Academy of Sciences.

MGH Cancer Center researchers find new gene associated with Wilms tumor
01-04-2007 · EurekAlert!
Researchers at the Massachusetts General Hospital Cancer Center have discovered a novel gene mutation associated with Wilms tumor, the most common pediatric kidney cancer. The newly identified gene is mutated in about 30 percent of cases of Wilms tumor and is located on the sex-determining X chromosome, which means that a single altered copy would be sufficient for tumor formation.

Depression often untreated in Parkinson's disease patients
07-09-2007 · EurekAlert!
While depression appears to be common in early Parkinson's disease (PD), it is often not treated or diagnosed, according to newly released research. A contingent of researchers from across North America found that just over 27 percent of PD subjects screened positive for depression, while 40 percent of subjects' depression went untreated. This study, is the first to systematically examine the impact of depressive symptoms in early, untreated PD.
