SINGAPORE (Reuters) – Scientists in China have demonstrated how arsenic -- a favorite murder weapon in the Middle Ages -- destroys deadly blood cancer by targeting and killing specific proteins that keep the cancer alive.
"Our study showed how arsenic directly targets these proteins and kills them," lead researcher Zhang Xiaowei at the State Key Laboratory of Medical Genomics in Shanghai, China, told Reuters.
"Unlike chemotherapy, the side effects of arsenic (in treating acute promyelocytic leukemia) are very low. There is no hair loss or suppression of bone marrow (function). We are interested in finding out how arsenic can be used in other cancers," Zhang said by telephone.
