- Novel regulation of the common tumor suppressor PTEN
01-11-2007 · EurekAlert!
PTEN is one of the most commonly mutated tumor suppressor genes. It is an antagonist for many cellular growth, proliferation and survival processes. When mutated or deleted, it causes cancers of the prostate, breast, colon and brain. Researchers led by scientists at Memorial Sloan-Kettering Cancer Center have now identified fundamentally novel regulatory mechanisms of PTEN function. The findings from two related studies are published in the Jan. 12 issue of Cell.

- A genetic 'gang of 4' drives spread of breast cancer
04-11-2007 · EurekAlert!
Studies of human tumor cells implanted in mice have shown that the abnormal activation of four genes drives the spread of breast cancer to the lungs. The new studies by Howard Hughes Medical Institute researchers reveal that the aberrant genes work together to promote the growth of primary breast tumors. Cooperation among the four genes also enables cancerous cells to escape into the bloodstream and penetrate through blood vessels into lung tissues.

- Signal protein shows promise for blocking tumor promoters in skin cells
11-03-2006 · EurekAlert!
A protein with the ironic name "Srcasm" can counteract the effects of tumor-promoting molecules in skin cells. Using animal models, the researchers discovered that Srcasm acts like a brake in epithelial cells, preventing uncontrolled cell growth caused by a family of proteins called Src kinases. This finding, published online in the Journal of Biological Chemistry, suggests a target for future gene therapy to treat skin, head, neck, colon and breast cancers.

- Targeting surgar on blood vessels may inhibit cancer growth
05-07-2007 · EurekAlert!
In a study that could point to novel therapies to prevent cancer spread, or metastasis, researchers at the University of California, San Diego, School of Medicine have targeted a sugar that supports blood vessel growth in the tumor. Their findings will be published in the May 7 online issue of Journal of Cell Biology.

- Blueberries contain chemical that may help prevent colon cancer
03-25-2007 · EurekAlert!
A compound in blueberries shows promise of preventing colon cancer in animals, according to a joint study by scientists at Rutgers University and the US Department of Agriculture. The compound, pterostilbene, is a potent antioxidant that could be developed into a pill with the potential for fewer side effects than some commercial drugs that are currently used to prevent the disease. The study will be presented in March during the American Chemical Society national meeting.

- Novel medication improves ovarian cancer treatment
10-31-2007 · EurekAlert!
A new study appearing in International Journal of Gynecological Cancer states that Bevacizumab, a biologic anticancer agent that prevents tumor growth by interfering with the formation of new blood vessels, may have the potential to improve the efficacy of standard combination chemotherapy in ovarian cancer.

- Enhanced DNA-repair mechanism can cause breast cancer
10-15-2007 · EurekAlert!
Although defects in the "breast cancer gene," BRCA1, have long been known to increase the risk for breast cancer, exactly how the defects lead to tumor growth has remained a mystery. Now scientists provide insight into how the normal BRCA1 gene suppresses the growth of tumors as well as the nature of the genetic instability that leads to cancer when BRCA1 is defective.
