Chemical switch triggers critical cell activities
01-16-2007 · EurekAlert!The freeze-frame image of a molecular relay race, in which one enzyme passes off a protein like a baton to another enzyme, has solved a key mystery to how cells control some vital functions, according to investigators at St. Jude Children's Research Hospital. A report on this work appears in the January 14 advanced online publication issue of Nature.

- Cold Spring Harbor Laboratory scientists discover new gene that prevents multiple types of cancer
02-09-2007 · EurekAlert!
A decades-old cancer mystery has been solved by researchers at Cold Spring Harbor Laboratory (CSHL). "We not only found a critical tumor suppressor gene, but have revealed a master switch for a tumor suppressive network that means more targeted and effective cancer therapy in the future," said CSHL Associate Professor Alea Mills, Ph.D. The study, headed by Mills, was published in the February issue of Cell.

- Soda warning? New study supports link between diabetes, high-fructose corn syrup
08-23-2007 · EurekAlert!
Researchers have found new evidence that soft drinks sweetened with high-fructose corn syrup may contribute to the development of diabetes, particularly in children. Drinks containing the syrup had high levels of reactive compounds that have been shown by others to have the potential to trigger cell and tissue damage that could cause the diabetes, a growing epidemic. The study will be presented in August at the American Chemical Society national meeting in Boston.

- SIV infection of natural hosts provides new insights into HIV disease complexity
09-06-2007 · EurekAlert!
Three related papers published in the Sept. 1 edition of the Journal of Immunology provide key new insights into the complexity of HIV/AIDS. Don Sodora, Ph.D., a principal investigator in SBRI's Viral Vaccines Program who recently joined SBRI from the University of Texas, Southwestern Medical Center, is senior author on one of three papers that collectively show CD4 T-cell depletion, a critical symptom of AIDS, is likely a part of a multifaceted scenario that triggers disease rather than the only cause.

- First Major Study Of Mammalian 'Disorderly' Proteins
10-10-2006 · ScienceDaily
Investigators at St. Jude Children's Research Hospital turned up the heat on "disorderly" proteins and confirmed that most of these unruly molecules perform critical functions in the cell. The St. Jude team completed the first large-scale collection, investigation and classification of these so-called intrinsically unstructured proteins (IUPs), a large group of molecules that play vital roles in the daily activities of cells.

- Low dose of serotonin-acting chemical improves blood sugar tolerance
11-06-2007 · EurekAlert!
An appetite-suppressing chemical also improves glucose tolerance and lowers insulin levels in obese and diabetic mice, researchers report in the November issue of Cell Metabolism, a publication of Cell Press. Importantly, the researchers found, those effects of the drug occurred at a low dose that had no influence on feeding behavior, body weight, activity level, or energy expenditure.

- Protein maintains cross talk between cells that control hair growth
02-14-2008 · EurekAlert!
Researchers at Rockefeller University have identified a signaling molecule that is critical for a type of skin cell, called dermal papilla, to ratchet up or clamp down the activity of genes that give them their molecular identity. Without these signals, these skin cells lose their hair-inducing properties -- findings that may provide a new understanding of how stem cells differentiate.

- Low doses of a red wine ingredient fight diabetes in mice
10-02-2007 · EurekAlert!
Even relatively low doses of resveratrol -- a chemical found in the skins of red grapes and in red wine -- can improve the sensitivity of mice to the hormone insulin, according to a report in the October issue of Cell Metabolism, a Cell Press publication. As insulin resistance is often characterized as the most critical factor contributing to the development of type 2 diabetes, the findings "provide a potential new therapeutic approach for preventing or treating" both conditions, the researchers said.

- New technique captures chemical reactions in a single living cell at unprecedented resolution
11-19-2007 · EurekAlert!
A team of UC Berkeley bioengineers have developed a technique that for the first time enables the detection of chemical signals from biomolecules in a single living cell with unprecedented resolution. By coupling metallic nanoparticles with biomolecules, researchers can obtain information critical to cell-based drug discovery, early disease detection and biomedical diagnostics.

- Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms
08-13-2007 · EurekAlert!
New evidence indicates that the loss of two types of brain cells -- not just one as previously thought -- may trigger the onset of symptoms associated with Parkinson's disease. The evidence, based on mouse models, shows a link between the loss of both norepinephrine and dopamine neurons and the delayed onset of symptoms associated with Parkinson's disease. It was originally thought that the loss of only dopamine neurons triggered symptoms. Dopamine is a neurotransmitter critical for coordinating movement.
