美国科学家日前发现,癌细胞能够迅速增殖是因为它们唤醒了一种叫做“PKM2”的丙酮酸盐激酶。据日前出版的《新科学家》杂志报道,健康细胞是把大部分葡萄糖作为“燃料”用来产生能量;而美国哈佛医学院的科学家发现,在癌细胞中,葡萄糖却是主要用来产生脂肪和脱氧核糖核酸等生成新 American scientists have discovered recently that cancer cells proliferate rapidly because they wake up a pyruvate kinase called “PKM2.” According to a report published recently by the “New Scientist” magazine, healthy cells use most of their glucose as a fuel to generate energy. However, scientists at Harvard Medical School find that in cancer cells, glucose is mainly used to produce fat and DNA and other new generation
