- Promising approach to a more effective sunscreen
12-03-2007 · EurekAlert!
Chronic sun exposure increases the risk of an individual developing skin cancer, because UV light from the sun can cause genetic mutations that enable skin cells to grow in an uncontrolled manner. Hope for a new sunscreen that can prevent and treat UV light-induced skin cancers has been provided by a new study that demonstrates that applying an agent known as CP-31398 to the skin of mice reduced a specific form of skin cancer.

- Gender linked to development of skin cancer
04-01-2007 · EurekAlert!
Inherent gender differences -- instead of more sun exposure -- may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center.

- Research linking Ashkenazi Jews and breast cancer genes beset by problems
11-01-2006 · EurekAlert!
Genetic research over the past decade has linked Ashkenazi Jewish ethnicity to an increased risk for hereditary breast cancer, so much so that certain gene mutations have become known as "Jewish ancestral mutations." But a new study released in the November 2006 issue of the American Journal of Public Health challenges this population-based approach, warning that disparities in access to care and other unintended consequences for specific ethic groups can result, and may have already occurred.

- More Sun Exposure May Be Good for Some People
01-07-2008 · Brookhaven National Laboratory
A new study by scientists at Brookhaven and colleagues in Norway suggests that the benefits of moderately increased exposure to sunlight may outweigh the risk of developing skin cancer in populations deficient in vitamin D.

- Mutation of the COX2 gene can double or treble a woman's risk of ovarian cancer
09-25-2007 · EurekAlert!
Researchers in Portugal have discovered that a specific mutation of the COX2 gene seems to play a role in the onset of ovarian cancer, increasing women's susceptibility to developing the disease. Dr. Ana Carina Pereira told the European Cancer Conference that the discovery raises the possibility that it might be possible to use nonsteroidal anti-inflammatory drugs, such as aspirin and ibuprofen, which are used already for other conditions, to prevent ovarian cancer developing in women with the COX2 mutation.

- MIT: Prenatal arsenic exposure detected in newborns
11-22-2007 · EurekAlert!
MIT researchers have found that 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. In addition to establishing the potential harmful effects of these prenatal exposures, the new study also provides a possible method for screening populations to detect signs of arsenic contamination.

- Presence of gene mutation helps guide thyroid cancer treatment
09-05-2007 · EurekAlert!
A specific gene mutation may be useful in predicting the level of aggression of thyroid cancer and help guide treatment options and follow-up care, according to new study findings.

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.
