美国科学家设计出一种“智能导弹”药物分子,能杀死癌细胞而不损害健康组织,用它治疗前列腺癌和乳腺癌的动物实验已经获得成功。这种“智能导弹”由两部分组成,一部分是负责使癌细胞自杀的蛋白质,另一部分是起“精确制导”作用的氨基酸短链,它能使药物准确作用于癌细胞。用 Scientists in the United States have designed a “smart missile” drug molecule that can kill cancer cells without harming healthy tissue. Animal experiments using it to treat prostate cancer and breast cancer have been successful. This “smart missile” consists of two parts, one part is the protein that is responsible for making cancer cells commit suicide, and the other part is a short chain of amino acids that plays a role of “precise guidance.” It can make drugs work accurately on cancer cells. use
