美国科学家研发出能安全运送高剂量抗癌药物直接抵达癌细胞的纳米运输系统,可大幅提高癌症治疗效果。多种癌细胞会大量生成基质金属蛋白酶。该酶能够促进癌细胞扩散,进而导致机体死亡。据美国加利福尼亚大学圣地亚哥分校官网报道,正是利用了这种酶的分解特性,该校化学和生物化学教授内森·詹内斯基领导的研究团队,发明了一种能在基质金属蛋白酶存在情况下释放药物的纳
American scientists have developed a nano-transport system that can safely deliver high-dose anti-cancer drugs directly to cancer cells, which can greatly improve the effectiveness of cancer treatment. A variety of cancer cells produce large amounts of matrix metalloproteinases. The enzyme can promote cancer cell proliferation, which in turn leads to death of the body. According to the official website of the University of California, San Diego, it is the decomposition characteristics of this enzyme that take advantage of the fact that the research team led by Nathan Jenningsky, a professor of chemistry and biochemistry at the university, has invented a method that can detect the presence of matrix metalloproteinases Under the release of the drug satisfied
