美国《科学》杂志近日发表一篇论文,介绍了一种全新的癌症靶向治疗方法,有可能遏制骨肉瘤、脑瘤以及某些胰腺肿瘤的生长,不过这种方法还有待通过临床研究来验证。这项研究通过阻断癌细胞用以维持增殖能力的信号通路,来达到抑制几种侵袭性肿瘤生长的目的。发现可预示癌细胞弱点的遗传标记物,开发针对这些弱点的新药,是当前癌症研究的一个焦点。论文共同通讯作者、马萨诸塞综合医院癌症中心科研副主任邹力告诉新华社记者,正常细胞如果不断分裂,其染色体末端会越来越短,最终 A recent paper published in the journal Science in the United States describes a new cancer-targeted therapy that may limit the growth of osteosarcomas, brain tumors and certain pancreatic tumors, but this remains to be confirmed by clinical studies . This study achieved the goal of inhibiting the growth of several aggressive tumors by blocking the signaling pathways that cancer cells use to maintain their ability to proliferate. Discovering genetic markers that can predict cancer cell weakness, and developing new drugs targeting these vulnerabilities, are a current focus of cancer research. Zhaoli, deputy director of research at the Massachusetts General Hospital Cancer Center told the Xinhua News Agency that if the normal cells continue to divide, their chromosome ends will be shorter and shorter, eventually
