Sour taste make you pucker? It may be in your genes

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.

1. 'Jumping genes' could make for safer gene delivery system
   09-26-2007 · EurekAlert!
   To move a gene from point A to point B, scientists and gene therapists have two proven options: a virus, which can effectively ferry genes of interest into cells, and a plasmid, an engineered loop of DNA that can do the same thing, albeit usually only on a short-term basis.

2. One gene 90 percent responsible for making common parasite dangerous
   12-14-2006 · EurekAlert!
   More than a decade of searching for factors that make the common parasite Toxoplasma gondii dangerous to humans has pinned 90 percent of the blame on just one of the parasite's approximately 6,000 genes. The finding, presented in this week's issue of Science, should make it easier to identify the parasite's most virulent strains and treat them.

3. 2 heads are better than 1: 2 dysfunctional DNA repair pathways kill tumor cells
   04-12-2007 · EurekAlert!
   Individuals who inherit one mutant copy of any one of about 12 genes that make the proteins of the Fanconi Anemia pathway are at increased risk of developing cancer. This occurs when the remaining "good" copy of the gene becomes mutated in a specific cell type. However, hope of a new treatment for these cancers has now been provided by a new study indicating that inhibiting the protein ATM can kill these cancer cells.

4. Identifying the mechanism behind a genetic susceptibility to type 2 diabetes
   08-01-2007 · EurekAlert!
   Type 2 diabetes is reaching epidemic proportions in the developed world. Determining if and how certain genes predispose individuals to type 2 diabetes is likely to lead to the development of new treatment strategies for individuals with the disease. A new study now shows that certain variants of the gene TCF7L2 make individuals more susceptible to type 2 diabetes and provides a mechanism by which these genetic variants might cause susceptibility to the disease.

    05-04-2007 · EurekAlert!
    Whippets are bred for speed and have been clocked at speeds approaching 40 miles per hour. Scientists at the National Human Genome Research Institute have now discovered a genetic mutation that helps to explain why some whippets run even faster than others. Published in the open-access journal PLoS Genetics, their findings will make for a fascinating experiment in applied genetics.
