 Research in the Linus Pauling Institute at Oregon State University suggests that some natural food compounds, which previously have been studied for their ability to prevent cancer, may be able to play a more significant role in treating it "“ working side-by-side with the conventional drugs that are now used in chemotherapy.A new study just published in the International Journal of Cancer examined the activity of chlorophyllin and found that, on a dose-by-dose basis, it was 10 times...

Antioxidant supplements do not appear to increase risk of melanoma, as previously suspected, according to a new report.Findings in a recent randomized trial of antioxidants for cancer prevention seemed to suggest daily supplementation with nutritionally appropriate doses of vitamins C and E, beta-carotene, selenium and zinc increased the risk of melanoma in women four-fold.

A U.S. biologist says the accumulation of metals in plants may be a strategy to protect the plants from predators such as prairie dogs. Postdoctoral researcher John Freeman of Colorado State University and colleagues said certain plant species growing on soils with high metal content, such as arsenic, copper, selenium or lead, accumulate large quantities of metals in their leaves and stems. The purpose of that hyperaccumulation isn't fully known, but Freeman said it might increase a plant's...

Higher selenium levels in the blood may worsen prostate cancer in some men who have the disease, U.S. researchers said. Researchers at Dana-Farber Cancer Institute in Boston and the University of California, San Francisco, said a higher risk of more-aggressive prostate cancer was seen in men with a certain genetic variant found in about 75 percent of the prostate cancer patients in the study. In those subjects, having a high level of selenium in the blood was associated with a two-fold...

Prairie dogs may seem like harmless little creatures, but they can inflict serious injury on plants simply by snacking on them. Plants cannot flee from their furry predators, so how do they avoid becoming a prairie dog's lunch?Dr. John Freeman and colleagues explore the role of metal hyperaccumulation in plant defense in the June 2009 issue of the American Journal of Botany.
