Diet and exercise key to surviving breast cancer, regardless of obesity, new UCSD study says
06-08-2007 · EurekAlert!
Breast cancer survivors who eat a healthy diet and exercise moderately can reduce their risk of dying from breast cancer by half, regardless of their weight, suggests a new longitudinal study from the Moores Cancer Center at the University of California, San Diego.

Dragons of hope: Boat racing improves lives of breast cancer survivors
02-01-2008 · EurekAlert!
Breast cancer survivors who participated in dragon boat racing reported significantly improved physical and mental health and coped better with post-recovery trauma, according to a study conducted by Dr. Catherine Sabiston of McGill's Department of Kinesiology and Physical Education. The results of her research -- conducted in Vancouver while she was a PhD student at the University of British Columbia -- were published in the Journal of Sport & Exercise Psychology at the end of 2007.

Yearly mammograms protect breast cancer survivors
07-20-2007 · EurekAlert!
Older women with breast cancer often receive less care than do younger ones. Now a study in the July 20, 2007 Journal of Clinical Oncology shows older women who get yearly mammograms after treatment of early-stage breast cancer are less likely to die from breast cancer. Researchers examined five years of follow-up on 2,000 patients age 65 and older with early-stage breast cancer at six systems in the Cancer Research Network, including Group Health.

Jefferson oncologists show breast cancers to be more aggressive in African-American women
07-09-2007 · EurekAlert!
A study of more than 2,200 women shows that African-Americans have more advanced breast cancer at the time of diagnosis than Caucasians. African-American women tend to have breast cancer tumor types that are more aggressive and have poorer prognoses. The findings are in line with other recent studies, and provide more evidence of the continuing need for early breast cancer screening for African-American women and the development of individual treatment strategies.

Study identifies women with breast cancer most likely to benefit from aromatase inhibitor
10-23-2006 · EurekAlert!
While some breast cancer survivors could benefit from adding aromatase inhibitors to the standard five years of tamoxifen, a new study shows the additional therapy should be weighed carefully for each individual. Tthe study's authors say potential improvement in cancer-free survival beyond five years with the added therapy may be less than two percent for most patients.

Adult survivors of childhood leukemia exercise less, worsening high risk for obesity and illness
07-23-2007 · EurekAlert!
Overcoming pediatric cancer may only mark the beginning of a young survivor’s lifelong battle to stay healthy. While survivors of childhood acute lymphoblastic leukemia (ALL) face an increased risk of developing serious health complications as a result of their cancer treatment, for a variety of reasons many avoid simple exercise and healthy lifestyle changes that could reverse the damage, according to a team of researchers based at Memorial Sloan-Kettering Cancer Center.

OHSU Cancer Institute shows findings of immunotherapy vaccine in prostate cancer patients
06-02-2007 · EurekAlert!
The study showed that sipuleucel-T did not significantly delay the time it took for a patient's PSA to reach a value of 3 ng/ml, the primary endpoint of the study, but it did show a prolongation in prostate-specific antigen doubling time (PSADT).

New study reveals for first time how BRCA1 mutations cause breast cancer
12-09-2007 · EurekAlert!
An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer. Findings show that one way BRCA1 mutations cause cancer is by knocking out a powerful tumor suppressor gene known as PTEN.

Advance in understanding of blood pressure gene could lead to new treatments
02-04-2007 · EurekAlert!
Research by scientists at UCL (University College London) has clearly demonstrated for the first time the structure and function of a gene crucial to the regulation of blood pressure. The discovery could be important in the search for new treatments for illnesses such as heart disease, the UK's biggest killer. In a paper published online today in Nature Medicine, the team, led by Professor Patrick Vallance and Dr James Leiper, UCL Department of Medicine, reveal the role of the human gene dimethylarginine dimethylaminohydrolase (DDAH), showing that loss of DDAH activity disrupts nitric oxide (NO) production. NO is critical in the regulation of blood pressure, nervous system functions and the immune system. The role of DDAH is to break down modified amino acids (Asymmetric dimethylarginine (ADMA) and monomethyl arginine (L-NMMA)) that are produced by the body and have been shown to inhibit NO synthase. These molecules accumulate in various disease states including diabetes, renal failure and pulmonary and systemic hypertension, and their concentration in plasma (the fluid component of blood) is strongly predicative of cardiovascular disease and death. In a healthy human body, the majority of ADMA is eliminated through active metabolism by DDAH. Scientists have hypothesised that if DDAH function is impaired, NO production is reduced, and that this could be an important feature of increased cardiovascular risk. To examine this pathway in more detail, the researchers deleted the DDAH gene in mice. These mice went on to develop hypertension, or high blood pressure. They also designed specific inhibitors (small molecules) which bind to the active site of human DDAH. These small molecule inhibitors also induced hypertension in mice, confirming the importance of DDAH in the regulation of blood pressure. Dr Leiper, UCL Medicine, said: “These genetic and chemical approaches to disrupt DDAH showed remarkably consistent results, and provide compelling evidence that loss of DDAH function increases the concentration of ADMA and thereby disrupts vascular NO signalling. “There has been considerable scientific interest in this pathway and the role of ADMA as a novel risk factor, but so far there's been little evidence to support the idea that it's a cause of disease, rather than just a marker. Genes and their pathways are crucial to our understanding of cardiovascular disease and a better understanding of DDAH-1 could lead to important new treatments. “It could help us to establish if genetic variation predisposes certain people to these diseases, or whether environmental factors exert some of their effects through modulation of DDAH activity. “Our research also shows that this pathway could be harnessed therapeutically to limit production of NO in certain situations where too much nitric oxide is a bad thing; for example, hypotension and septic shock. These are some of the biggest problems in intensive care medicine and there is a huge unmet need for drug treatments.” The study, which was carried out at UCL's Rayne Institute, was funded by grants from the British Heart Foundation, the Wellcome Trust and the Medical Research Council. Professor Jeremy Pearson, Associate Medical Director of the British Heart Foundation, said: "The unexpected finding in the 1980s that a simple gas, nitric oxide (NO), is made by cells in the blood vessel wall and is a powerful control of blood vessel relaxation led to the award of the Nobel Prize in 1998 to its discoverers. "More recently, there has been increasing evidence that impairment of NO production is likely to be an important factor in the development of heart and circulatory disease, but the mechanisms responsible are not fully understood. "This study suggests for the first time that the loss of the activity of the enzyme DDAH-1 leads to reduced NO production and may cause heart and circulatory disease. These findings are likely to be important in the search for new ways to optimise the health of our blood vessels." ### Notes for Editors 1.

Stanford scientists make major breakthrough in regenerative medicine
04-24-2007 · EurekAlert!
Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine -- a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.
