Casting out devils
Salmonella are regarded as bad guys. Hardly a summer passes without severe salmonella infections via raw egg dishes or chicken that find their way into the media. But salmonella not only harm us – in future they may even help to defend us against cancer. The bacteria migrate into solid tumors and make it easier to destroy them.
Natural compounds, chemotherapeutic drugs may become partners in cancer therapy
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.
Fine-tuning an anti-cancer drug
Cancer remains a deadly threat despite the best efforts of science. New hopes were raised a few years ago with the discovery that the uncontrolled growth of cancer cells could be thwarted by blocking the action of proteasomes. Biochemists at the Technische Universitaet Muenchen (TUM) have illuminated a reaction pathway that does just that, in collaboration with researchers from Nereus Pharmaceuticals, based in San Diego, California. In the current issue of the Journal of Medicinal Chemistry, they report insights that could potentially lead to the development of custom-tailored anti-cancer drugs.
New Hope for Deadly Childhood Bone Cancer
Researchers at Huntsman Cancer Institute (HCI) at the University of Utah have shed new light on Ewing’s sarcoma, an often deadly bone cancer that typically afflicts children and young adults. Their research shows that patients with poor outcomes have tumors with high levels of a protein known as GSTM4, which may suppress the effects of chemotherapy. The research is published online today in the journal Oncogene.
Nano-bio material kills cancer cells, leaves healthy cells unharmed
Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to soft biological material.
