Genes offer researchers a 'crystal ball' to help them prevent, diagnose and treat cancer
11-12-2006 · EurekAlert!The science of cancer prevention has advanced to the point where researchers now say they can detect "cancer genes" in the breath of smokers, and can test the presence of two proteins in men they say will predict development of prostate cancer a decade in advance.

- Jefferson scientists uncover gene mutation that cuts colon polyps, may suppress cancer
03-21-2007 · EurekAlert!
Scientists have found a gene mutation that can dramatically reduce the number of colon polyps that develop, potentially cutting the risk of cancer. Researchers studying mice prone to develop polyps discovered that animals carrying the damaged gene had about 90 percent fewer polyps in the small intestine and colon. Because people with large numbers of polyps are at higher risk for colon cancer, the finding may provide new ways to diagnose, prevent and treat it.

- Firefly genes allow testing of new therapy against lymphoma
12-19-2007 · EurekAlert!
Researchers here have figured out a way to use a firefly gene to let them see just how effective a new drug combination actually is against some forms of cancer and its serious complication. The new study looked at ATLL, adult T cell lymphoma and leukemia, a form of cancer where it is particularly hard to gauge the disease's progress, and where the patients' prognosis is generally poor. There is now no widely effective therapy available to treat this disease successfully.

05-18-2007 · EurekAlert!
Investigators at St. Jude Children's Research Hospital have gained some of the first major insights into how certain genes known to prevent cancer also guide the normal development of the nervous system before birth and during infancy by repairing DNA damage.

- Prenatal arsenic exposure can alter genes
11-22-2007 · Massachusetts Institute of Technology (MIT)
The children of mothers whose water supplies were contaminated with arsenic during their pregnancies harbored gene expression changes that may lead to cancer and other diseases later in life, MIT researchers reported in a new study.

- Researchers find suntan's 'master regulator'
03-08-2007 · EurekAlert!
A gene known to prevent cancer also acts as a master regulator of the suntan response, researchers report in the March 9, 2007 issue of Cell, published by Cell Press. The team discovered in studies of mice and human skin that p53, a gene best known for keeping tumors at bay, is ultimately responsible for activating the tanning machinery that darkens the skin of so many sun-seeking beachgoers, thereby protecting them from sunburns.

07-24-2007 · EurekAlert!
Surprising findings by Queen's University researchers have shed new light on how the "sunshine vitamin" D -- increasingly used to treat and prevent cancer and other diseases -- is broken down by our bodies.

- DNA computing targets West Nile Virus, other deadly diseases
10-16-2006 · EurekAlert!
Researchers say that they have developed a DNA-based computer that could lead to faster, more accurate tests for diagnosing West Nile Virus and bird flu. Representing the first 'medium-scale integrated molecular circuit,' it is the most powerful computing device of its type to date, they say. In the future, the new technology could be used to develop instruments that can simultaneously diagnose and treat cancer, diabetes or other diseases, the scientists suggest.

01-18-2007 · EurekAlert!
DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

- Australian researchers develop treatment to treat obesity
11-06-2007 · EurekAlert!
A team of Australian researchers have developed a novel way to control the extreme weight loss, common in late-stage cancer, which often speeds death. The findings published today in Nature Medicine suggest it may soon be possible to prevent this condition, giving people the strength to survive treatment and improve their chances of recovery.
