BostonBTS writes "Researchers from TransMolecular, Inc. have used chlorotoxin -- a component of giant yellow scorpion venom -- to target radioactive treatments for the deadly brain cancer glioma. From the article: 'In the study, 18 patients first had surgery to remove malignant gliomas, a lethal kind of brain tumor. Then doctors injected their brains with a solution of radioactive iodine and TM-601, the synthetic protein. The solution bound almost exclusively to leftover tumor cells, suggesting that it could be combined with chemotherapy to fight cancer. Furthermore, two study patients were still alive nearly three years after the treatment.' Their paper is slated for publication in the August issue of the Journal of Clinical Oncology."
