自杀基因杀癌逄丽萍译金一人校鼠肝内癌的扩散能通过使肿瘤细胞自杀的一种实验性基因疗法而大为减小。其研究人员希望将这种方法适用于癌患者，使肝脏清除往往是致命的继发肿瘤。在查尔斯顿的马萨诸塞综合医院的泰珀及其同事已经发明了一种把“自杀基因”引入癌细胞的改进... The spread of suicide gene-killing tumors in liver cancer in mice has been greatly reduced by an experimental gene therapy that kills tumor cells. The researchers hope that this method will be applied to cancer patients, so that the removal of the liver is often a fatal secondary tumor. Tepper and his colleagues at the Massachusetts General Hospital in Charleston have invented an improvement in the introduction of “suicide genes” into cancer cells...
