- Study offers innovative profile of enzyme that aids tumor growth
10-20-2006 · EurekAlert!
Using an innovative profiling strategy, scientists at the Scripps Research Institute have characterized an enzyme that is "highly elevated" in aggressive human tumor cells. When the enzyme, KIAA1363, was inactivated, it impaired tumor growth and migration in both ovarian and breast cancer cells, suggesting that inhibitors of this enzyme may prove valuable in the treatment of multiple types of cancer.

- Low folate diets found to increase risk of colorectal cancer
11-02-2006 · EurekAlert!
A new study by scientists at the MUHC has revealed that a diet low in folate may increase the risk of developing colorectal cancer. Published in the scientific journal Cancer Research today, the study not only illustrates a way to prevent the disease but also provides further insight into the mechanisms of the disease, which could lead to novel therapies.

- Growth factor signals influence balance between normal growth and cancerous growth
11-09-2006 · EurekAlert!
Too much of a signaling protein called insulin-like growth factor-I (IGF-I) may fan the flames of cancer, while too little of the protein may cause short stature, dementia and osteoporosis. New research investigates how the growth hormone/IGF system is affected by the important tumor suppressor gene p53. This interplay of two signaling pathways reinforces questions about the long-term risks of prescribing growth hormone, while suggesting a future new avenue for cancer therapy.

- Malaria may fuel spread of HIV in sub-Saharan Africa
12-07-2006 · EurekAlert!
Malaria may be fueling the spread of HIV in areas of sub-Saharan Africa where there is a substantial overlap between the two diseases, while HIV may be playing a role in boosting adult malaria-infection rates in some parts of the region, according to a new study by researchers at Fred Hutchinson Cancer Research Center and the University of Washington.

- First familial pancreatic cancer gene identified
12-11-2006 · EurekAlert!
At least 10 percent of pancreatic cancers are thought to be familial, i.e., caused by inherited genetic mutations. The responsible genes have so far remained elusive, but one of the research teams that had been on a pancreatic cancer gene hunt for years now reports success: Teri Brentnall (University of Washington), David Whitcomb (University of Pittsburgh), and colleagues publish the identification of the palladin gene as the one mutated in a large family they had been studying for a while.

- Two studies: Speeding development of novel tracer for prostate cancer
01-02-2007 · EurekAlert!
The collaborative work being performed by professionals across medical disciplines in the promising area of molecular imaging -- from research scientists to nuclear medicine physicians, urologists, radiochemists and even veterinarians -- provides encouraging news in fighting prostate cancer. This type of progressive -- or translational -- research can be seen in two papers published in the January issue of the Journal of Nuclear Medicine.

- Chemicals in brown algae may protect against skin cancer
01-25-2007 · EurekAlert!
Substances extracted from a marine seaweed may protect against skin cancer caused by too much sun, new research suggests. The animal study indicates that chemicals called brown algae polyphenols (BAPs), which are found in a type of brown marine seaweed, might protect against skin cancers caused by ultraviolet B (UVB) radiation.

- Leukemia drug turns mini-molecules up, cancer genes down
03-01-2007 · EurekAlert!
New research shows that a form of vitamin A used to treat acute promyelocytic leukemia induces changes in an unusual class of small molecules called microRNAs (miRNAs) in the leukemic cells. The study also shows that three of these miRNAs inhibit the action of two genes important for cancer development, helping to explain how the drug works.
