Researchers at Johns Hopkins and Ohio State University have found that the number of copies of a particular gene can affect the severity of colon cancer in a mouse model. Publishing in the Jan. 3 issue of Nature, the research team describes how trisomy 21, or Down syndrome in humans, can repress tumor growth.

While investigating how the hormone orexin might control sleep and hunger, researchers at UT Southwestern Medical Center have discovered, to their surprise, that it activates a protein, HIF-1, long known to stimulate cancerous tumor growth.

Zinc, an important trace element for healthy growth and development, can be related to pancreatic cancer.

A diet low in carbohydrates may help stunt the growth of prostate tumors, according to a new study led by Duke Prostate Center researchers. The study, in mice, suggests that a reduction in insulin production possibly caused by fewer carbohydrates may stall tumor growth

Scientists at Sunnybrook have new information that may help to improve the use of anti-cancer drugs designed to block the growth of new blood vessels in tumors, a process called angiogenesis that is critical to tumor growth.

So vital is the p53 tumor suppressor gene in controlling cancer that its dysfunction is linked to more than half of human cancers. At the same time, the gene’s capacity for shutting down cell growth, even causing cells to commit suicide if necessary, is so absolute that it must be tightly regulated to maintain the optimal balance between protecting against cancer and permitting normal growth.

Fat in the stomach may cause vitamin C to promote, rather than prevent, the formation of certain cancer causing chemicals, reveals research published ahead of print in the journal Gut.

A University of Bath researcher has been awarded more than £1 million to study a group of molecules involved in the growth of tumours.

New data produced by Andrei Thomas-Tikhonenko and colleagues at the University of Pennsylvania, Philadelphia, provides a molecular mechanism by which a protein known as PAX5 promotes the growth of a number of types of lymphoma.

Based on their surprising discovery that an obesity drug can kill cancer cells, scientists at Wake Forest University School of Medicine have made a new finding about the drug’s effects and are working to design more potent cancer treatments.

Using mathematical theory, UC Irvine scientists have shed light on one of cancer's most troubling puzzles - how cancer cells can alter their own genetic makeup to accelerate tumor growth. The discovery shows for the first time why this change occurs, providing insight into how cancerous tumors thrive and a potential foundation for future cancer treatments.

Flaxseed, an edible seed that is rich in omega 3-fatty acids and fiber-related compounds known as lignans, is effective in halting prostate tumor growth, according to a study led by Duke University Medical Center researchers. The seed, which is similar to a sesame seed, may be able to interrupt the chain of events that leads cells to divide irregularly and become cancerous.
