Antioxidant found in many foods and red wine is potent and selective killer of leukemia cells

04-23-2007 · EurekAlert!

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine. These findings, which were published online March 20 in the Journal of Biological Chemistry and will be in press May 4, offer hope for a more selective, less toxic therapy for leukemia.

  1. Red alert: Wild strawberries may reduce cancer risk
    12-02-2007 · EurekAlert!
    We've all seen the term "super food" used to describe those nutrition-loaded edibles that promote health and discourage disease. Powerhouse foods high in antioxidants and phytochemicals that block the development of cancer cells have been touted as nature's way to fight off the potentially devastating disease.

  2. New discovery could reduce the health risk of high-fat foods
    01-02-2008 · EurekAlert!
    Just as additives help gasoline burn cleaner, a research report published in the January 2008 print issue of The FASEB Journal shows that the food industry could take a similar approach toward reducing health risks associated with fatty foods. These "meal additives" would be based on work of Israeli researchers who discovered that consuming polyphenols (natural compounds in red wine, fruits, and vegetables) simultaneously with high-fat foods may reduce health risks associated with these foods.

  3. Novel 3-D cell culture model shows selective tumor uptake of nanoparticles
    08-23-2007 · EurekAlert!
    A novel cell culture model consisting of an aggregate of brain tumor cells growing on normal thin slices of brain tissue has been developed to investigate tumor properties and therapy. The tumor cells showed a similar invasion pattern to that seen when growing in patients. When nanoparticles made from a new type of polymer were added to the co-culture, the nanoparticles were taken up more by the tumor cells than the normal brain cells.

  4. A type of antioxidant may not be as safe as once thought
    09-04-2007 · EurekAlert!
    According to new research at the University of Virginia Health System, N-acetylcysteine (NAC), an antioxidant commonly used in nutritional and body-building supplements, can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen. This leads to pulmonary arterial hypertension (PAH), a serious condition characterized by high blood pressure in the arteries that carry blood to the lungs.

    07-16-2007 · EurekAlert!
    Exploiting interactions between food and drugs could dramatically lower the costs of some anti-cancer drugs -- and many other medications. Certain foods aid absorption or delay breakdown of these drugs. Two cancer-pharmacology specialists suggest the "Value Meal," a novel way to decrease costs and increase benefits from these effective but expensive drugs.

    Yale researchers now have some answers about how the bacterium that is the leading cause of food-borne illness in the United States enters cells of the gut and avoids detection and destruction, according to a presentation at the annual meeting of the American Society for Cell Biology in San Diego in December.

  7. Despite their heft, many dinosaurs had surprisingly tiny genomes
    03-07-2007 · EurekAlert!
    They might be giants, but many dinosaurs apparently had genomes no larger than that of a modern hummingbird. So say scientists who've linked bone cell and genome size among living species and then used that new understanding to gauge the genome sizes of 31 species of extinct dinosaurs and birds, whose bone cells can be measured from the fossil record.

  8. Progress toward a targeted therapy for a specific form of leukemia
    04-15-2007 · EurekAlert!
    Leukemia strikes some 700 Belgians each year. Scientists are still searching for the cause of many forms of leukemia, including T cell acute lymphoblastic leukemia, or T-ALL. Now, VIB researchers connected to the Katholieke Universiteit Leuven have identified a new player in the development of some 10 percent of the T-ALL cases: MYB.

    04-24-2007 · EurekAlert!
    A study carried out by researchers from the University of Granada's Institute of Biotechnology proves that consuming melatonin neutralizes oxidative damage and delays the neurodegenerative process of ageing. In this study researchers used normal and genetically-modified mice which were subjected to accelerated cell aging, although their results can also be applied to humans.

  10. Pathway to cell death redefined in landmark study
    09-20-2007 · EurekAlert!
    Researchers from the University of Pittsburgh School of Medicine have determined that an intracellular protein called serpin-6 is crucial to the repair and survival of cell injury. Controlling the process could pave the way to new treatments for cancer, stroke, heart disease, neurological disorders and other killer illnesses. Using a primitive animal model, the scientists also have made cascade of cell death and the role of serpin-6 in saving cells dramatically -- and explosively -- visible.
