当前科学家已首次获得具体证据,表明癌症是由正常细胞内染色体的正常基因的作用所致。尽管上述证据来自小鼠的试验,但支持了一种理论,即当细胞内被称作癌基因的特殊基因发生异常,就出现肿瘤。上述结果清楚地表明,癌瘤有代代相传的倾向。哈佛医学院遗传学教授Philip Leder于1984年9月在波士顿举行的“肿瘤的分子生物学会”上宣布了以上的实验结果。癌基因的概念可溯至七十年代中期,当时科学家证明,将实验室培育的细胞暴露于某些
For the first time, scientists have obtained concrete evidence that cancer is caused by the normal genes of chromosomes in normal cells. Although the above evidence comes from experiments in mice, it supports the theory that tumors appear when abnormal genes in a cell called an oncogene are abnormal. The above results clearly show that cancers have a tendency to pass on from generation to generation. Professor Philip Leder, Professor of Genetics at Harvard Medical School, announced the above experimental results at the “Molecular Biology Conference on Cancer” held in Boston in September 1984. The concept of oncogenes dates back to the mid-1970s, when scientists demonstrated exposure of laboratory-grown cells to certain
