Talcum powder stunts growth of lung tumors

University of Florida researchers say talc is an exciting new therapeutic agent for a cancer largely considered incurable. Talc stimulates healthy cells to produce endostatin, a hormone considered valuable for treating metastatic lung cancer.

1. 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.

   Scientists at the University of North Carolina at Chapel Hill School of Medicine and Harvard Medical School have found that a mutated tumor suppressor gene, LKB1, may result in lung tumors that are more aggressive and more likely to spread throughout the body.

3. Flaxseed stunts the growth of prostate tumors
   06-02-2007 · EurekAlert!
   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.

   11-13-2007 · EurekAlert!
   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.

5. Study suggests existing drugs may be useful in treating brain tumors
   10-15-2007 · EurekAlert!
   Scientists have shown how developing brain tumors can turn an encounter with a signaling molecule from a fatal experience for the tumor cells into a cue for their own growth and multiplication. The transformation relies on two molecules that can be modified with existing drugs, opening the possibility of using them to treat brain tumors.

   01-09-2008 · EurekAlert!
   The drug sirolimus, normally used to help transplant patients fight organ rejection, may eventually be used as a less invasive treatment for a tumor called angiomyolipomata in patients with tuberous sclerosis complex or lymphangioleiomyomatosis who would otherwise face surgery. The finding is reported by investigators from Cincinnati Children's Hospital Medical Center and the University of Cincinnati College of Medicine in the Jan. 10 edition of the New England Journal of Medicine.

9. Jefferson scientists find tumor suppressor gene protects against pre-cancerous development
   11-01-2006 · EurekAlert!
   Cell biologists have provided further evidence that a gene thought to play a role in suppressing tumors actually protects against the development of pre-cancerous cell growth as well. The researchers say that the gene, caveolin-1, which they found in two major types of breast cells, could be a potential target for future drugs aimed at preventing breast cancer. The work also suggests a potentially important role of the tumor "microenvironment" in the cancerous process.

    08-15-2007 · EurekAlert!
    Researchers at Mayo Clinic Jacksonville, have found that a key gene is often "silenced" in clear cell renal cell carcinoma, the most common type of kidney cancer, and when they restored that gene in human kidney cancer cells in culture and animal experiments, tumors stopped growing and many disappeared.
