Researchers identify gene that plays key role in size of dogs
04-05-2007 · EurekAlert!An international team of scientists, including researchers from Cornell University, have found a mutation in a single gene that plays a key role in determining body-size differences within and among dog breeds and probably is important in determining the size of humans as well.

- Pioneering study looks at p53's role in tumor-stroma interactions
10-25-2006 · EurekAlert!
Researchers have conducted the first comprehensive study of the role an important tumor suppressor gene plays in cancer development. P53 is known as a major tumor suppressor that is frequently mutated in human cancer. In this study, researchers used novel proteomic techniques to identify the proteins secreted by cells specifically in response to p53. The findings suggest a newfound role for wt-p53 in the control of the tumor's ability to communicate with the normal stromal cells surrounding it.

- Researchers identify genetic mutation that may alter tumor cell proliferation
07-04-2007 · EurekAlert!
Researchers from Eli Lilly & Company and the Phoenix-based Translational Genomics Research Institute today announced finding a novel recurring mutation of the gene AKT1 in breast, colorectal and ovarian cancers. The altered form of AKT1 appears to cause tumor cell proliferation and may play a role in making cells resistant to certain types of therapies. The findings are reported in an advance online publication of the journal Nature.

- Lessons in wood formation from Arabidopsis
03-01-2007 · EurekAlert!
In two separate studies published in The Plant Cell, researchers identify key transcription factors that control the expression of genes related to secondary wall formation in the model herbaceous plant Arabidopsis. The presence of similar genes and pathways in tree species suggests that they may play a role in the regulation of wood formation in trees.

- Scientists identify a candidate gene for osteoporosis
03-28-2007 · EurekAlert!
Researchers report the identification of a gene that may play a role in susceptibility to osteoporosis -- the crippling disease that leads to bone fractures, especially of the hip and spine. The study, conducted by scientists at the Musculoskeletal Diseases Center of the Jerry L. Pettis Memorial Veteran's Affairs Medical Center at Loma Linda, shows convincing evidence that a gene called DARC negatively regulates bone density in mice.

- Gene found to play a suppressor role in skin cancer development
02-06-2008 · EurekAlert!
Researchers at the Burnham Institute for Medical Research have provided genetic evidence that Activating Transcription Factor 2 plays a suppressor role in skin cancer development. ATF2 is a protein that regulates gene transcription, the first step in the translation of genetic code, in response to extracellular stresses such as ultraviolet light and ionizing radiation. This function of ATF2 in stress and DNA damage response suggests it may also play a role in tumor formation.

- 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.

- Researchers identify molecules with interesting anti-clotting properties
11-08-2007 · EurekAlert!
Virginia Commonwealth University researchers have discovered a new mechanism to inhibit key enzymes that play a major role in clotting disorders, which could lead to novel therapies to treat clots in the lungs and those localized deep in the body in areas such as the legs.

- Researchers identify cell pathway in colon cancer
02-20-2007 · EurekAlert!
Researchers have identified a cell pathway which plays a critical role in the development of colon cancer. This pathway may also play a role in the development of lung and stomach cancers. Investigators say they have identified STAT3 {signal transducer and activator of transcription 3}, as a target regulated by PTPRT {Receptor Protein tyrosine phosphatase T}, which was previously identified to be mutated in colon, lung and stomach cancer patients.

- Sour taste make you pucker? It may be in your genes
07-11-2007 · EurekAlert!
Scientists at the Monell Chemical Senses Center report that genes play a large role in determining individual differences in sour taste perception. The findings may help researchers identify the still-elusive taste receptor that detects sourness in foods and beverages, just as recent gene studies helped uncover receptors for sweet and bitter taste.
