Gallium: A new antibacterial agent?

New antibacterial strategies are needed because more and more bacteria are antibiotic resistant and because antibiotics are not effective at eradicating chronic bacterial infections. In a new study, using Gallium (Ga) to limit the amount of iron (Fe) to which bacteria have access protected mice from both acute and chronic Pseudomonas aeruginonsa lung infections, leading to the suggestion that Ga might be a promising new therapeutic for the treatment of infection with P. aeruginonsa.

2. Novel gallium compound may offer treatment for lymphoma patients with resistant disease
   12-11-2006 · EurekAlert!
   Christopher Chitambar, M.D., a physician researcher at the Medical College of Wisconsin Cancer Center in Milwaukee, has identified a compound that may be effective in treating forms of non-Hodgkin's lymphoma (a cancer of the lymphatic system) that are resistant to certain therapies. The new agent could also offer the advantages of being administered orally, rather than intravenously, making it more convenient than intravenous agents.

   11-16-2006 · EurekAlert!
   Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food. Composed of apple puree and oregano oil, which is a natural antibacterial agent, the coating shows promise in laboratory studies of becoming long-lasting alternative to conventional produce washes, according to a team of scientists from the US Department of Agriculture (USDA) and the University of Lleida in Spain.

   Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi’s sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis. Researchers at the University of Helsinki have discovered that activation of the p53 pathway offers a novel effective treatment modality for KSHV-infected lymphomas.

   05-08-2007 · EurekAlert!
   Researchers at Washington University School of Medicine in St. Louis report they have developed an agent that protects cells from the lethal effects of radiation, regardless of whether it is given before or after exposure. Using this agent in mice, the investigators found that the treatment helped shield rapidly dividing cells that are most vulnerable to radiation-induced death, providing proof in principle that it is possible to fend off radiation damage.

   12-03-2007 · EurekAlert!
   Chronic sun exposure increases the risk of an individual developing skin cancer, because UV light from the sun can cause genetic mutations that enable skin cells to grow in an uncontrolled manner. Hope for a new sunscreen that can prevent and treat UV light-induced skin cancers has been provided by a new study that demonstrates that applying an agent known as CP-31398 to the skin of mice reduced a specific form of skin cancer.

    12-20-2007 · EurekAlert!
    The veil has finally been lifted on an enzyme that is critical to the process of DNA transcription and replication, and is a prime target of antibacterial and anticancer drugs. Researchers with the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeleyhave produced the first three-dimensional structural images of a DNA-bound Type II topoisomerase (topo II) that is responsible for untangling coiled strands of the chromosome during cell division.
